Problems solved by technology

[0002] At present, the lifting tools of the cable trench cover basically use the principle of leverage. When lowering the cover, it often requires the cooperation of multiple people. One of them controls the lifting truck of the cable trench cover, and the others cooperate to adjust the lowering position of the cover. At the same time, the lowered cover plate needs to adjust the gap with another cover plate (requires no gap), generally need to use tools such as crowbar, this way is easy to cause damage to the cover plate
At the same time, due to its own structural reasons, the cable trench cover lifting truck can only transport one cover at a time. After the installation is completed, another cover needs to be installed and fixed at the corresponding stacking position, and then the crane is pushed to the designated working position. Collaborate to complete the installation, but only a small number of people are on duty during the actual work, unable to complete the daily maintenance of the cable trench
[0003] The Chinese invention patent with the application number 201310503367.0 discloses a cable trench cover lifting device, including a lever, a lever sleeve, a bearing, a load-bearing bracket, a universal wheel, a grab hook and a chain; the lever is movably connected to the bearing through the lever sleeve , the bottom end of the bearing is fixed on the load-bearing bracket; each corner of the bottom end of the load-bearing bracket is provided with a universal wheel; one end of the lever is fixedly connected to N chains, N≥2, and the other end of each chain is A grabbing hook is provided; the cable trench cover lifting device of the present invention uses the principle of leverage to hook the cable cover, and uses the flexible steering function of the universal wheel to place the lifting cover aside. Although this device can lift the cable trench cover The purpose of the board, but the degree of automation of the whole device is not high

Abstract

The invention discloses a substation indoor cable trench cover plate hoisting device which comprises a transporting cart (1) and a transporting cart rear rack (2), wherein the transporting cart rear rack (2) is connected with the transporting car (1). The hoisting device is characterized by further comprising a rotation device (3), a winch (4), a hoisting arm (5), an oil cylinder (6), a clamping board device (7), a hydraulic pressure station (9) and a steel wire rope (101). According to the hoisting device, the rotation device, the winch, the hoisting arm, the oil cylinder and the clamping board device are used in a combined manner, so that automatic hoisting of a cable trench cover plate is achieved and human cost and work intensity are reduced; the transporting cart and the transporting car rear rack can accommodate trench cover plates with various sizes through the coordination of dovetail grooves and dovetail keys, the range of application is wider, and meanwhile the risk that the trench cover plate falls down is reduced; the clamping board device can clamp and hold the trench cover plates with various sizes, and the application range and stability are improved; and the use of a knocking device can achieve automatic knocking on the trench cover plates, and the efficiency of the entire hoisting device is improved.
