Background
The cable trench is used for laying underground places of cables, and the cable trench cover plate needs to meet certain pressure bearing, so that the volume and the weight of the cable trench cover plate are large. When a transformer substation is newly built in a power system or a technical improvement project is performed, cable laying operation is often involved, a cable trench cover plate is firstly completely lifted and moved beside a cable before cable laying, and then the cable trench cover plate is covered again after the cable laying is completed. Because the gaps around the cable trench cover plate are small, the weight of the cable trench cover plate is heavy, the cable trench cover plate can drop into a trench and damage a running cable in the trench due to carelessness during moving, accidents are caused, and the labor intensity of manual operation is high and the work efficiency is low.
When the cable is laid or overhauled in a small range, a large amount of manpower and material resources are consumed when large-scale hoisting equipment such as a forklift or a crane is used, and the construction is not economical.
SUMMERY OF THE UTILITY MODEL
The utility model aims to overcome the above-mentioned defect that current cable trench cover exists, provide a novel rocking arm formula cable trench cover, simple structure, reasonable in design, through the articulated front and back apron that sets up of trailing rail cooperation, the apron is opened more conveniently, the operator of being convenient for is under construction.
The utility model discloses an adopt following technical scheme to realize:
a novel rocker arm type cable trench cover plate comprises a cover plate seat, wherein the rear end of the cover plate seat is hinged with a front cover plate, and the rear end of the front cover plate is hinged with a rear cover plate through a hinge arranged at the bottom; and supporting rails matched with the side edges of the bottom parts of the front cover plate and the rear cover plate are arranged on the two sides of the front cover plate and the rear cover plate, and the supporting rails are fixedly arranged on the cover plate seat.
Preferably, two sides of the rear end of the rear cover plate are rotatably connected with bearing rollers, the bearing rollers are fixed on the rear cover plate through a fixed shaft, and a bearing retainer ring is arranged between the bearing rollers and the rear cover plate; the bearing roller is adapted to the support rail and can roll along the support rail. The bearing idler wheel can roll along the supporting rail, so that the front cover plate and the rear cover plate can be opened in a rolling mode, and labor is saved for opening the front cover plate and the rear cover plate.
Further preferably, the top of the rear end of the front cover plate is hinged with a handle, and the handle is rotatably arranged in a groove in the top surface of the front cover plate.
Further preferably, a sealing strip is arranged between the front cover plate and the rear cover plate to prevent water from flowing into the space between the front cover plate and the rear cover plate to corrode the hinge.
The utility model has the advantages that:
(1) the novel rocker arm type cable trench cover plate of the utility model divides the cover plate into a front cover plate and a rear cover plate, the front cover plate and the rear cover plate are hinged, and the front cover plate and the rear cover plate are simultaneously matched with the support rail at the bottom, so that the cover plate can be conveniently opened, an operator can enter the cable trench to carry out operation, or the front cover plate and the rear cover plate can be maintained;
(2) the novel rocker arm type cable trench cover plate is provided with the bearing idler wheel, and the bearing idler wheel is matched with the support rail in a rolling way, so that the front cover plate and the rear cover plate can be opened more conveniently;
(3) a novel rocking arm formula cable trench apron, be provided with the sealing strip, prevent that water from flowing into and corroding the hinge between front shroud and the back shroud.
