DETAILED DESCRIPTION

[0034] The present disclosure relates to a hose reel for winding or unwinding a flexible hose having a flexible cord embedded therein. Here, the hose reel is configured to unwind the flexible hose wound on a winding shaft of a rotating disk inside a basket of the hose reel and push the same into a drain pipe while rotating the flexible cord using the rotational force of a rotating means disposed on the rotating disk of the hose reel to rotate together with the rotating disk so as to rotate a tool fixed to the flexible cord protruding from the leading end of the flexible hose, thereby unclogging the drain pipe.

[0035] The rotating means according to the present disclosure is operated by means of a torque impact switch or a remote control carried by a user (e.g., a mechanic) to control the operation and the RPM of the rotating means. Thus, the operation may be performed by a single mechanic alone, even when not working in close proximity to the hose reel.

[0036] In the hose reel according to the present disclosure, a cylindrical basket is fixed within a prefabricated rectangular frame, the flexible hose inserted in a withdrawal hole of the basket is wound on or unwound from the winding shaft of the rotating disk fitted in the basket to rotate, and the flexible cord embedded in the flexible hose protrudes above the rotating disk to receive a rotational force from the rotating means. A height-adjustable base member is disposed on the rotating disk. A torque impact wrench serving as the rotating means is fixed to the base member, and the shaft fixed to the flexible cord is fitted into a chuck of the torque impact wrench. Accordingly, the flexible cord is rotated using the torque impact wrench serving as the rotating means. In this process, the torque impact wrench may be controlled by means of a torque impact switch or a remote control.

[0037] The hose reel according to the present disclosure is fixedly inserted into the prefabricated rectangular frame, and the operation of the hose reel is enabled by the rectangular frame. However, due to the base member protruding in one direction, the operation is not stable and may fall during the transportation and operation, and a protruding work member may have a negative effect on the operation. In order to overcome these problems, another rectangular frame may be fitted to the rectangular frame to which the basket is fixedly fitted. Thus, the base member may also be protected using the rectangular frame. Auxiliary equipment necessary for the operation may be received in the other rectangular frame for transportation.

[0038] Hereinafter, embodiments of the present disclosure will be described in detail with reference to the accompanying drawings.

[0039] According to the present disclosure, a cylindrical basket 20 having a floor may include a support rod 21 erected in the center of the basket 20. The rectangular frame 10 may be formed by assembling known structures, with the basket 20 being disposed therein. The basket 20 disposed within the rectangular frame 10 may be fixed. Separate rectangular frames continuous from both sides of the rectangular frame 10 may be constructed by assembling the known structures. Within such a rectangular frame, the basket for receiving the auxiliary equipment may be fixedly disposed.

[0040] The upper end of said basket 20 is closed with a rotating disk 30. The winding shaft 31 projects from the center of the lower surface of the rotating disk 30. The rotating disk 30 rotates in a position in which the said winding shaft 31 is fitted around the support rod 21 of the basket 20. In the central portion of the rotating disk 30, a fixing bolt 32 extends through the basket 20 and is fastened to the rotating disk 30, so that the rotating disk 30 may only rotate in the coupled position.

[0041] The flexible hose 1 is wound on the winding shaft 31 of the rotating disk 30. One leading end of the flexible hose 1 wound on the winding shaft 31 is fixed to the rotating disk 30 by means of a fastener 40, and a flexible cord 2 embedded in the flexible hose 1 fixed to the fastener 40 protrudes above the rotating disk 30 through the fastener 40. The flexible cord 2 protruding above the rotating disk 30 is rotatably fitted into a support 46 and is fixed to a shaft 47 protruding above the support 46. The support 46 and the fastener 40 are configured to be coupled to each other by means of a one-touch socket 45. Accordingly, in a state in which the one-touch socket 45 is fastened, when the shaft 47 is rotated, the flexible cord 2 rotates. In a state in which the support 46 and the fastener 40 are separated by means of the one-touch socket 45, oil is injected into the fastener 40 to reduce the resistance of the flexible cord 2 rotating within the flexible hose 1. The flexible cord 2 may be easily replaced as necessary.

[0042] Here, the fastener 40 serves to fix the flexible hose 1 to the rotating disk 30. The shaft 47 is coupled to the support 46 in a rotatable manner so as to protrude therefrom. The flexible cord 2 extending through and protruding from the fastener 40 is fixed to the shaft 47. In a position above the rotating disk 30, corresponding ends of the support 46 and the fastener 40 are coupled to the one-touch socket 45. Accordingly, the support 46 and the fastener 40 may be easily coupled to or decoupled from each other by means of the one-touch socket 45.

[0043] The flexible hose 1 wound on the winding shaft 31 rotating together with the rotating disk 30 is withdrawn through one of withdrawal holes formed in corners of the rectangular frame 10. A tool 3 is fixed to the leading end of the flexible cord 2 embedded in the flexible hose 1. Accordingly, when the flexible cord 2 is rotated by means of the shaft 47, the tool 3 is rotated. In this state, when the flexible hose 1 is pushed into the drain pipe, the rotating tool 3 may clear a clog in the drain pipe.

[0044] The structure for providing the flexible hose 1 with flexibility and preventing the flexible hose 1 from being damaged using the flexible cord 2 during rotation of the flexible cord 2 embedded in the flexible hose 1 according to the present disclosure is disclosed in Korean Patent Application No. 10-2022-0170140 filed by the applicant.

[0045] In the hose reel according to the present disclosure, the flexible hose 1 is wound or unwound by rotating the rotating disk 30. After the tool 3 fixed to the flexible cord 2 embedded in the flexible hose 1 is pushed into the drain pipe, the shaft 47 protruding above the rotating disk 30 is rotated by means of the torque impact wrench 60 so as to rotate the tool 3, thereby clearing the drain pipe. In this process, the flexible hose 1 is pushed in or withdrawn.

[0046] According to the present disclosure, a base member 50 is fixed to the upper portion of the rotating disk 30, and the height of the base member 50 is adjusted. The torque impact wrench 60 is located on the upper portion of the base member 50 and is fixed by means of a fixing member 55 such that the chuck 61 of the torque impact wrench 60 is fixed in a downward orientation. Thus, torque impact wrench 60 is fixed, with the chuck 61 being fitted to the shaft 47. Here, the torque impact wrench 60 is fixed, with the chuck 61 of the torque impact wrench 60 being fitted to the shaft 47, by adjusting the height of the base member 50.

[0047] Here, the base member 50 may be fixed by disposing legs in three or four directions in order to firmly fix the torque impact wrench 60 rotating. the chuck 61 The height of the base member 50 may be adjusted by means of a variable method such as screw turning method or a link adjustment method. The base member 50 may be easily realized by a person having ordinary knowledge in the art, even with structural differences, as long as the base member 50 supports the torque impact wrench 60, which is the basic function of the base member 50, and is height adjustable.

[0048] In addition, as illustrated in the figures, after full threaded bolts 51 are fixed on the upper portion of the rotating disk 30 in a rectangular arrangement, the base member 50 according to the present disclosure may be fixed by means of the full threaded bolts 51.

[0049] According to the present disclosure, an operation switch of the torque impact wrench 60 may be fixed so as to be pressed by a C-shaped adjustment member 65, in which the degree of pressing of the operation switch may be adjusted according to the degree of tightening an adjustment screw provided on one side of the adjustment member 65.

[0050] That is, after the adjustment member 65 is disposed so as to press the operation switch of the torque impact wrench 60, the operation and RPM control of the torque impact wrench 60 may be performed by pressing the operation switch of the torque impact wrench 60 according to the degree of tightening of the adjustment screw on one side of the adjustment member 65. Because pressure by which the adjustment member 65 presses the operation switch of the torque impact wrench 60 may be adjusted, the RPM of the torque impact wrench 60 may be adjusted to an intended state without a separate operation, and the adjusted state of the adjustment member 65 may be maintained unless the adjustment screw is unscrewed.

[0051] Accordingly, a mechanic may work alone to clear a drain pipe by pushing the tool 3 into a drain pipe while holding the flexible hose 1 in a state in which the flexible cord 2 is rotated at an intended speed by the RPM control of the torque impact wrench 60 using the adjustment member 65 as described above. Because the tool 3 rotates at the RPM previously adjusted using the adjustment member 65, the mechanic may work alone without separately controlling the RPM of the tool 3 during the operating process. However, this method may make it difficult to control the RPM of the torque impact wrench 60 during the operating process.

[0052] In order to overcome this problem, the torque impact may be controlled using a manual switch 71 using a controller 70 or be controlled remotely using the remote control 75. After a battery is removed from the torque impact wrench 60, the controller 70 according to the present disclosure is fastened to a battery mounting portion of the torque impact wrench 60, and the power supply battery is coupled to the controller 70. The controller 70 may have a function of turning on and off power transmitted from the battery to the torque impact wrench 60, a function of simply controlling the RPM of the manual switch 71 disposed on a side thereof, and a function of working in concert with the remote control 75 carried by the mechanic, thereby allowing the mechanic to perform on/off and RPM controls using the remote control 75.

[0053] That is, according to the present disclosure, the battery is removed from the torque impact wrench 60, the controller 70 is fastened to the torque impact wrench 60, the battery is connected to the controller 70 to supply power, and then the switch of the torque impact wrench 60 is turned on. In this state, the on/off and RPM controls of the torque impact wrench 60 are performed using the controller 70 by performing on/off control on power application to the torque impact wrench 60 using the controller 70.

[0054] The controller 70 is configured to control the operation and RPM of the torque impact wrench 60 using the torque impact switch 71 disposed on a side thereof or control the operation and RPM of the torque impact wrench 60 using the remote control 75. In a case where the torque impact switch 71 is used, the mechanic is close to the hose reel. In a case where the remote control 75 is used, the mechanic works alone while being spaced apart from the hose reel.

[0055] According to the present disclosure, when the controller 70 is fastened to the battery mounting portion of the torque impact wrench 60, the battery is connected to the controller 70, and then the switch of the torque impact wrench 60 is set to an on position as described above, the operation and RPM control of the torque impact wrench 60 may be performed by the torque impact switch 71 and the remote control 75. Accordingly, the mechanic may maintain the torque impact wrench 60 in the optimal working environment by selectively using the manual switch 71 or the remote control 75.

[0056] The remote control 75 carried by the mechanic may perform the on/off and RPM controls on the torque impact wrench 60 by means of the remote control 75. In a case where the mechanic works alone, the mechanic may operate the torque impact wrench 60 using the remote control 75 while pushing the flexible hose 1 into the drain pipe by holding the leading end of the flexible hose 1, thereby allowing the tool 3 to rotate to clear the drain pipe. Accordingly, the mechanic may work alone by adjusting the RPM of the torque impact wrench 60.

[0057] As set forth above, according to the present disclosure, the mechanic may operate the hose reel while controlling the RPM of the torque impact wrench 60 by pushing the tool 3 into the drain pipe at a position spaced apart from the hose reel. Accordingly, the mechanic may operate the hose reel alone in a simple manner, and labor costs may be reduced.
