Description
Technical Field
The invention relates to a foldable cable support, and belongs to the technical field of laying of power cables in cable trenches.
Background
The cable tunnel and the cable trench are main channels for city power supply, and cable supports made of angle iron are adopted for erecting cables for a long time. The angle iron bracket is usually formed by connecting or splicing angle iron sections through welding or fasteners. The cable support is suitable for being welded with a trench wall embedded part, the welded part is anticorrosive, the installation is firm, the horizontal and vertical directions are realized, the same-layer horizontal struts of the supports are arranged on the same horizontal plane, the height deviation is less than or equal to 5mm, and the cable support arranged in a cable trench with a slope or on a building has the same slope as that of the cable trench or the building. The distance from the uppermost layer and the lowermost layer of the cable support to the top of the trench, the floor or the bottom of the trench and the ground is in accordance with the regulations of the Cable line construction and acceptance Specification of Electrical apparatus installation engineering (GB 50168).
Before the cable lays, the cable support has already been installed fixedly in the cable pit and has accomplished for originally narrow cable pit in the residual space more narrowly, further lay in place and personnel's removal in the ditch for the cable has brought obstacle and inconvenience. The technical difficulty of cable laying is increased due to the problems of the existing cable bracket, and unnecessary working hours are increased; moreover, when emergency repair of cable faults is carried out in the cable trench, due to the limitation of space, some fault troubleshooting equipment is difficult to enter the cable trench; narrow and small space has restricted the translation rate of maintainer in the channel, and this has all prolonged the investigation and the repair time of cable fault, and then has prolonged the power transmission time, has brought unnecessary economic loss for power consumption enterprise and customer.
Disclosure of Invention
The invention aims to provide a foldable cable support, which designs an originally fixed horizontal cable support into a foldable type, and can upwards rotate and retract a horizontal cable support rod to be vertical to the ground before cable laying or during cable fault maintenance, so that the moving space in a cable channel is furthest expanded, and convenience is provided for moving maintenance personnel in the channel and entering maintenance equipment.
The foldable cable support is arranged in a cable channel and comprises a cable support body, wherein the cable support body is fixedly provided with a connecting rod parallel to the wall of the cable channel, the connecting rod is connected with a cable supporting rod vertical to the wall of the cable channel through a rotating shaft, a limiting block is arranged above the cable supporting rod at a non-cantilever end on one side of the rotating shaft, and the limiting block is fixed on the cable support body; the surface of the cable support body fixed with the cable channel wall is provided with a support fixing bolt.
The cable support body is fixed on the inner wall of the cable channel through the support fixing bolt, and in a working state, the cable support rod is in a horizontal state, the cable support rod at the non-cantilever end on one side of the rotating shaft is limited by the limiting block, so that the cable support rod is kept horizontal, and a cable is arranged above the cable support rod; when overhauls or other reasons need great space, upwards rotates the cable supporting rod around the pivot, and the upper surface of transposition cable supporting rod contacts with the stopper, and the cable supporting rod upwards rotates 90 and ground vertical state promptly. And under the limiting effect of the limiting block, the cable supporting rod can only complete 90-degree rotation at most.
Preferably, the cable support body be equipped with 2 layers or more than 2 layers of cable support pole, the connecting rod length that next layer cable support pole is connected is greater than the sum of the connecting rod length that last layer cable support pole is connected and the width of cable support pole to the relevant position of every layer of cable support pole top all is equipped with the stopper. Generally, a plurality of groups of cables need to be transported in the same cable channel, so that a plurality of layers of cable support rods are needed to play a role in supporting and transporting. The connecting rod length that next layer cable support pole is connected is greater than the total of the connecting rod length that last layer cable support pole is connected and the width of cable support pole, can effectively prevent that every layer of cable support pole from disturbing each other when upwards rotatory folding to can make cable support pole upwards rotatory folding to the maximum angle, furthest is cable channel release space.
Preferably, the upper surface of the cable support rod below the limiting block is provided with a clamping groove, the shape of the clamping groove is matched with that of the limiting block, and the upper end of the limiting block is higher than the upper surface of the cable support rod. The lower part gomphosis of stopper is in the draw-in groove to the upper end of stopper is higher than cable support pole upper surface, can make the stopper play better limiting displacement.
Preferably, the middle section part undercut of cable supporting rod be the concave surface, make things convenient for placing of cable, can effectively prevent the cable landing.
Preferably, the concave surface part of the cable supporting rod is provided with a through hole, so that rainwater and the like can be drained in time, the air permeability is increased, and the heat dissipation of the cable is facilitated.
Preferably, the cable support pole below set up and support the angle iron, the extending direction that supports the angle iron is parallel with the connecting rod, plays effective supporting role to the cable support pole.
The pivot has certain damping, and only when the exogenic action, the cable supporting rod just can rotate around the pivot, consequently, when the cable supporting rod changes to perpendicular with ground, if do not have exogenic action cable supporting rod then can not oneself change to the horizontality.
Compared with the prior art, the invention has the beneficial effects that:
(1) the invention enhances the safety of the laying work of the power cable in the cable channel. The brackets in a conventional cable channel extend inward from the channel wall and are easily scratched by the extending cable brackets when a service person moves in the channel. In the patent, the support can be completely folded upwards when necessary, so that the safety of a maintainer moving in a channel is greatly improved;
(2) the working efficiency is improved, and the working hours are saved. Firstly, the larger in-ditch space after the support is retracted improves the moving speed of the maintainers in the ditch, and meanwhile, after the space is enough, the maintainers which cannot enter the ditch originally due to the volume can move and be used in the cable ditch, so that the working efficiency of the operation in the cable ditch is further improved;
(3) has certain economic benefit. The improvement of the efficiency of the overhauling construction operation in the cable inevitably reduces the preparation time of power transmission, accelerates the power transmission speed and reduces the economic loss of power utilization enterprises caused by delaying the power transmission.
