Abstract

An integral rescue accessory for forcible entry and core drill may include hydraulic wall saws, a rotating platform, and a coring claw. Two hydraulic wall saws are symmetry installed on rotating platform. The wall saws cut linearly with the rotation of rotating platform to open a rectangular tunnel on a reinforced concrete wall or floor. After the cutting process, coring process is finished by the wall saws and claw inclinedly mounted to ensure the security of rescue. The whole accessory is installed on a large engineering machine through a hydraulic joint. The present disclosure can transfer general large mechanical equipment into dedicated large mechanical equipment quickly.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0019] The preferred embodiments will be described accompanied by appended drawing.

[0020] As shown in the figure, an integral rescue accessory for forcible entry and core drill may include hydraulic wall saws (A), a rotating platform, and a coring claw (B).

[0021] The hydraulic wall saws (A) may include: diamond saw blade (1), a wall saws support frame (9), a wall saws linear slider (10), a hydraulic motor (11), a hydraulic arm (12), a wall saws mounting (13), a wall saws guide roller (14), a wall saws travel motor (15), a wall saw hydraulic joint (16) and a spline (17). The diamond saw blade (1) is driven by a hydraulic motor (11) to proceed cutting down through swinging the hydraulic arm (12). The whole mainframe of hydraulic wall saws is installed on the linear slider (10), and it is driven by wall saws travel motor (15), guide roller (14) is guiding along the spline (17) to proceed straight-line cutting. Wall saws support frame (9) and wall saws mounting (13) are installed with a certain angle to make the angle between diamond saw blade (1) and cutting plane normal be 10.

[0022] The rotating platform may include a general hydraulic joint (3), a rack (4), a rotating platform (7), a turntable (8) and a servomotor (22). The top of rack connects with a general hydraulic joint (3) configured to cut with a large-scale engineering equipment, and the bottom of rack connects with rotating platform (7).

[0023] The coring claw including a claw hydraulic drive cylinder (2), a claw connector (5), a claw (6), a claw mounting bracket (18), a hydraulic drive cylinder mounting bracket (19), a claw arranging slider (20), and a claw linear guideway (21). Two claw mounting brackets (18) are arranged on the turntable (8), and claw hydraulic drive cylinder (2) is arranged on two claw mounting brackets (18). Claw hydraulic drive cylinder (2) connects with a claw (6) through claw connector (5). The extension and recovery of the claw (6) are driven by telescoping of the hydraulic cylinder. Claw (6) is arranged on claw arranging slider (20) which can slide along the claw linear guideway (21). Claw mounting bracket (18) is designed with a certain angle which also makes the angle between claw (6) and cutting plane normal is 10 so that the claw can extend into the kerf to finish grabbing.

[0024] After completing cutting cut of one rectangular side by the hydraulic wall saw blade, the rotating platform rotates 90 to finish cutting on the other side. At the same time, the claw extends into the gap to hold the coring of concrete that had been cut. After all the cutting work is done, the saw blades are taken back through the cantilever. The coring of concrete is lifted by a mechanical arm of the large engineering machine, the claw is taken back, the coring of concrete slips off, and the entire process of drilling and coring is finished.

[0025] Rescue work is done by connecting hydraulic joint (3) with a hydraulic system of the engineering machine.
