Abstract

The invention discloses a cable trench cover plate dismounting device. A stand column is arranged on the upper portion of a base; a first lifting arm is hinged to the upper end of the stand column; a hydraulic cylinder is hinged to the lower portion of one side of the stand column; a first lifting bracket is connected to the lower portion of a first lifting hook through a first lifting chain and comprises a second lifting arm and second lifting brackets arranged at the two ends of the second lifting arm; a clamping hook is disposed on the lower portion of a second lifting chain; and the upper portion of the clamping hook is connected with the second lifting chain through a third lifting hook. During use, the dismounting device is moved onto the upper portion of a cable trench cover plate, the hydraulic cylinder is controlled to contract to enable the first lifting arm to descend, after the clamping hook is inserted into a water leakage hole of the cable trench cover plate, the clamping hook is rotated by 90 degrees to enable the two sides of the clamping hook to hook the cable trench cover plate, and then the hydraulic cylinder is controlled to extend to enable the first lifting arm to ascend so as to hoist the cable trench cover plate, one person can finish the dismounting operation, so that the dismounting cost of the cable trench cover plate is reduced, and the dismounting safety of the cable trench cover plate is ensured.

Description

technical field [0001] The invention belongs to the technical field of electric power construction, in particular to a device for disassembling and assembling cable trench cover plates. Background technique [0002] The cable is the main artery of the substation. The normal operation of the cable is related to the safety of the entire power grid and is the top priority in the operation and maintenance of the substation. One of the difficulties in cable operation and maintenance is the removal of the cable trench cover. The cable trench is usually constructed of reinforced concrete, which is bulky and heavy. In the investigation involving the cable trench cover, a lot of manpower and material resources are required. Usually, in the investigation of cable trenches, two to three people are required to remove the cover plates, and four to six people are required to move a large number of cover plates such as cable trench cleaning and cable fire protection renovation. Moreover,...
