Cable trench cover plate opening device

Abstract

The invention discloses a cable trench cover plate opening device which comprises a vehicle body and a hanging plate, wherein a stand column is arranged on one side of the upper portion of a chassis, a pinch bar is hinged to the upper end of the stand column, a hydraulic cylinder is hinged to one side of the stand column, a connecting rod is hinged to the other end of the pinch bar, the hanging plate is arranged on the lower portion of the connecting rod, hanging rods are arranged on the lower portions of supporting arms, the outer portion of each hanging rod is connected with a sliding sleeve in a sliding mode, a first abutting plate is arranged on one side of the lower portion of each hanging rod, the lower end of each first abutting plate is hinged to a second abutting plate through a second pin shaft, the lower end of each hanging rod is movably installed on the corresponding second pin shaft through a shaft sleeve, one side of each sliding sleeve is hinged to a first connection rod, the lower end of each first connection rod is hinged to the inner wall of the corresponding first abutting plate, the other side of the sliding sleeve is provided with a second connection rod, and the lower end of each second connection rod is hinged to the inner wall of the corresponding second abutting plate. According to the cable trench cover plate opening device, the hanging plate is arranged on the front portion of the vehicle body, the hanging rods are arranged on the lower portion of the hanging plate, the first abutting plates and the second abutting plates are arranged on the lower portions of the hanging rods, a cable trench cover plate is pried through the first abutting plates and the second abutting plates, and damage to the cable trench cover plate is avoided.

Description

technical field [0001] The invention belongs to the technical field of electric power maintenance, and in particular relates to an opening device for a cable trench cover. Background technique [0002] The cable trench is a channel with a cover plate. The shape of the cover plate is generally rectangular and the thickness is uniform. When laying and maintaining cables, the cover plate must be uncovered. The traditional method of uncovering the cover plate is that the operator holds a crowbar to pry into the cover plate into the rectangular hole on the cover, and then forcefully pry the cover off. [0003] Because the rectangular holes on the cover plate are located on both sides of the cover plate, if the traditional method is used to remove the cover, no matter which end the operator pries, it will be more difficult, requiring more effort, which is time-consuming and laborious. In addition, prying the cover plate with a crowbar , The rectangular hole of the cover plate is ...

Problems solved by technology

[0003] Because the rectangular holes on the cover plate are located on both sides of the cover plate, if the traditional method is used to remove the cover, no matter which end the operator pries, it will be more difficult, requiring more effort, which is time-consuming and laborious. In addition, prying the cover plate with a crowbar , the rectangular hole of the cover plate is a fulcrum with a large force, which is easy to cause the rectangular hole to be enlarged, or the cover plate is worn, which will affect the cover plate to cover the cable trench again
