DETAILED DESCRIPTION OF EMBODIMENTS

[0043] Specific embodiments of the present application will now be described in detail with reference to the figures. The embodiments described herein are only preferred embodiments according to the present application. Those skilled in the art can envision other modes capable of implementing the present application on the basis of the preferred embodiments, and said other modes also fall within the scope of the present application.

[0044] The cable laying device 100 as disclosed in the present application can reach the technical effects of applying mechanical devices to transport and lay cables as shown in FIG. 1, thereby reducing labor cost during oil field operations as well as avoiding severe cable damage during manual cable hauling. Besides, the cable laying device 100 disclosed in the present application can be adapted to different laying conditions defined by different electrical equipment, thereby improving the efficiency during cable laying. Specifically, as shown in FIG. 1, the cable laying device can lay the cables, in the way of mechanical driving, to a certain height, at a certain angle as well as in a certain length to a position which is most convenient for electrical equipment.

[0045] Referring to FIG. 1 and FIG. 2, it can be seen that the cable laying device 100 comprises: a cable laying part having a base section 11 and a length adjustable extension section 12; a turnover mechanism 20 and a positioning adjustment mechanism 30. Specifically, the base section 11 and the extension section 12 are such connected with each other at their longitudinal ends that they are moveable relative to each other, and can accommodate, transport and lay cables. Specifically, depending on the application, the extension section can be provided at one or both longitudinal ends of the base section. In this case, the extension section 12 can be extended from the base section 11 according to the working environment of the electrical equipment. In order to further achieve the flexibility in use, the cable laying device 100 further comprises a positioning adjustment mechanism 30 including a rotating assembly 31 which can be connected to the base section 11, i.e. at a position such as one longitudinal end or a certain longitudinal position of the base section 11, so that the base section 11 or the cable laying part can rotate driven by the rotating assembly, thus the cable laying device can be applied at different installation positions of electrical equipment. The cable laying device 100 comprises a turnover mechanism 20, wherein the turnover mechanism 20 connects the base section 11 with the extension section 12, so that the extension section 12 can be driven to turn over in different angles from the base section 11 depending on the requirements, thereby realizing different heights and lengths of the whole cable laying part and hence different cable laying solutions.

[0046] It needs to be explained here that in the present application, the “longitudinal position” of the base section 11 refers to the position along the length direction of the base section 11 or the extension section 12.

[0047] Optionally, in order to enable the cable laying device 100 to be better applicable to electrical equipment of different heights, the positioning adjustment mechanism 30 may also have a lifting unit 32 for adjusting the height of the cable laying part. Here, in order to avoid the interference with the rotating movement of the cable laying part, the rotating assembly 31 can be arranged at the lifting unit 32 and the lifting unit 32 is connected to the cable laying part or the base section 11 via the rotating assembly 31. The rotating assembly 31 can drive the base section or the cable laying part to rotate around the lifting unit 32.

[0048] To be specific, optionally, the rotating assembly 31 may be configured as a gear transmission assembly known in the prior art, wherein the gear transmission assembly may be driven by an external motor or other driving mechanism, and its output part may be configured to connect with and drive the base section 11 into rotating.

[0049] Optionally, as shown in FIG. 3, the turnover mechanism 20 that drives the extension section 12 to perform turnover movement may comprise a turnover driving part 21 and a bar transmission assembly 22 driven by the turnover driving part 21. Specifically, the bar transmission assembly 22 includes a first bar element 221 and a second bar element 222, wherein one end of the first bar element 221 is connected to the base section 11, and the other end is pivotally connected to the second bar element 222, meanwhile, the other end of the second bar element 222 is connected to the extension section 12, and the base section and the extension section are connected with each other via a pivot shaft 13, so that the first bar element 221, the second bar element 222, the base section 11 and the extension section 12 can form a four-bar linkage mechanism. In this case, the turnover driving part 21 connects and drives the pivot shaft between the first bar element 221 and the second bar element 222 to perform linear reciprocating movement, so that the second bar element 222 drives the extension section 12 to perform turnover movement.

[0050] Alternatively, the turnover driving part 21 may also be connected to and drive the first bar element 221 which is connected with the base section 11 to reciprocatingly rotate, so as to enable the second bar element 222 to drive the extension section 12 for performing turnover movement.

[0051] Within the scope of the present application, optionally, the turnover driving part 21 may be configured to comprise a turnover driving hydraulic cylinder, wherein the piston 211 of which may be connected with the bar transmission assembly i.e. the pivot shaft between the first bar element 221 and the second bar element 222 or the first bar element 221, so as to drive the bar transmission assembly 22.

[0052] Within the scope of the present application, optionally, in order to achieve a more stable and balanced turnover movement, the turnover mechanism 20 may be arranged along the longitudinal direction of the pivot shaft 13 between the base section 11 and the extension section 12, for example, may be arranged in pairs at longitudinal ends of the pivot shaft 13.

[0053] Since that, during operation of the cable laying device 100, the cable laying part is often held in a certain height in the form of an elongated load-bearing part, in order to stabilize the height of the elongated cable laying part, the cable laying device 100 disclosed in the present application may optionally further include a height-holding mechanism 40, which may be arranged together with the lifting unit 32 of the positioning adjustment mechanism 30 and maintain the desired height of the cable laying part. Specifically, the height-holding mechanism 40 may be configured to connect to the positioning adjustment mechanism 30 at one end while connect to the base section 11 at the other end, specifically connect at a longitudinal position other than the installation position of the positioning adjustment mechanism 30 or the rotating assembly 31 of the base section 11, and hold the height of the cable laying part. That is, the height-holding mechanism 40 may be arranged along the longitudinal tilted direction relative to the cable laying part.

[0054] In this case, optionally, the positioning adjustment mechanism 30 may be provided at one longitudinal end of the cable laying part or the base section 11, while the height-holding mechanism 40 can support the cable laying part at another longitudinal position of the base section 11, thereby improving the stability of the cable laying part. For example, it can be considered that the height-holding mechanism 40 may comprise a hydraulic cylinder, wherein a piston is connected with the base section 11 and supports the cable laying part through telescopic movement.

[0055] In order to more conveniently transport the cable laying device 100, the cable laying device 100 can also comprise a carrying mechanism 50. It can be considered that the carrying mechanism 50 includes a semi-trailer, a vehicle-mounted structure or a skid-mounted structure, on the chassis 51 of which the positioning adjustment mechanism 30 can be fixedly arranged.

[0056] In the case where there exists a carrying mechanism 50 or a semi-trailer, a vehicle-mounted structure or a skid-mounted structure, when the cable laying part is rotated 90 degrees or more relative to the carrying mechanism 50, it is possible that the center of gravity of the entire cable laying device 100 deviates from the carrying mechanism 50 and moves toward the cable laying part. Therefore, in order to maintain the stability of the carrying mechanism 50 in the above operating conditions, the cable laying device 100 may optionally include a lifting leg assembly 60, which comprises at least one lifting leg 61 that supports and stabilizes the carrying mechanism 50 via lifting motion or telescopic movement. The lifting legs may be connected at both lateral sides of the chassis 51 of the semi-trailer, vehicle-mounted structure or skid-mounted structure (as shown in FIG. 1 or 2). Depending on the degree the cable laying part have rotated relative to the chassis 51, the lifting leg is configured to be able to rotate into different angles relative to the chassis 51, thereby achieving optimal supporting for the carrying mechanism 50.

[0057] Furthermore, within the scope of the present application, the connection direction between the extension section 12 and the base section 11 is not limited. That is, at the longitudinal ends of the extension section 12 and the base section 11, the extension section 12 may include an extension section connected to the longitudinal extension surface of the base section 11 or an extension section connected to the lateral side surface of the base section 11. In other words, when the extension section 12 is connected at the longitudinal extension surface of the base section 11, the extension section 12 can lie on the longitudinal extension surface of the base section 11 when it is not “extended” or “turned over”, while when the extension section 12 is connected at both lateral sides of the base section 11, the extension section 12 can abut against the lateral sides of the base section 11 when it is not “extended” or “turned over”.

[0058] The cable laying device disclosed by the present application can conveniently and efficiently realize electricity supply to a plurality of electrical equipment. As shown in FIG. 1, depending on the location of the electrical equipment and site restrictions, the cable laying device can enable the cable laying part or the base section as well as the extension section to rotate by a certain angle (e.g., 90 degrees in FIG. 1) by means of the rotating assembly, and adjust the height of the cable laying part by using the lifting unit, so that the rotating position and height of the cable laying part can be more suitable for connecting the electrical equipment. In addition, according to the number of electrical equipment and the height of their connectors, the extension section of the cable laying part can correspondingly turn over a certain angle relative to the base section to form a certain inclination, so as to supply the electrical equipment with electricity. Therefore, the cable laying device disclosed by the present application can not only reach a high cable laying efficiency, but also reduce the abrasion of the cables through the cable carrying and protecting effects accomplished by the cable laying part.

As described above, various alternatives and modifications of the present application will be apparent to those of ordinary skill in the art.
