Problems solved by technology

[0003] 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 method 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
[0004] 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 trench cover plate lifting device. The trench cover plate lifting device comprises a transporting vehicle (1) and a transporting vehicle back frame (2). The transporting vehicle back frame (2) is connected with the transporting vehicle (1). The trench cover plate lifting device is characterized by further comprising a rotating device (3), a winch (4), a lifting arm (5), an oil cylinder (6), a plate clamping device (7), a hydraulic station (9) and a steel wire rope (101). According to the trench cover plate lifting device, automatic lifting of cable trench cover plates is achieved through combined use of the rotating device, the winch, the lifting arm, the oil cylinder and the plate clamping device, the human cost is reduced, and the working intensity is relieved; the transporting vehicle and the transporting vehicle back frame can contain trench cover plates with different sizes through matching of dovetail grooves and dovetail keys, the application range is wider, and meanwhile, the sliding risk of the trench cover plates is reduced; the trench cover plates with different sizes can be clamped through the plate clamping device, the application range is expanded, and the stability is improved; and the trench cover plates can be automatically knocked by using a knocking device, so that the efficiency of the whole device is improved.

Description
