Description

Technical Field

[0001] The utility model relates to the technical field of cable laying, in particular to a cable laying structure which is easy to adjust. Background Art

[0002] Cables are laid in cable trenches and tunnels and are generally fixed with brackets. Commonly used brackets include angle steel brackets and prefabricated brackets. There are 7 different models and specifications of angle steel brackets used in cable trenches. The vertical distance between bracket layers is 300mm for installing 35kV cables, and 120mm is for installing control cables.

[0003] At the construction site of the power distribution network, temporary construction electricity is involved. The commonly used temporary cable laying method is to adopt the method of manual lifting. If the cable falls accidentally, because the cable is heavy, the downward impact force is also large. If there are sharp objects on the ground, it is likely to damage the outside of the cable, causing wear and tear, affecting the cable construction. At present, there are also support frames for cable support, but most of them are not equipped with buffer devices, and cannot buffer the impact force when the cable falls, and cannot make appropriate adjustments to the height according to the terrain.

[0005] In order to achieve the above-mentioned purpose of facilitating height adjustment, a cable laying structure that is easy to adjust includes a placement seat, a base is fixedly installed on the bottom of the placement seat, an adjustment device is fixedly installed on the outer side of the placement seat, the adjustment device includes a motor, a threaded rod, a movable rod, a hinged seat, a slider, a clamping block and a lifting plate, a threaded rod is fixedly installed on the output shaft of the motor, the outer side of the threaded rod is threadedly connected to the movable rod, the bottom of the movable rod is hinged with an hinged seat, the bottom of the hinged seat is fixedly installed with a slider, the outer side of the slider is fixedly installed with a clamping block, and the side of the movable rod away from the slider is hinged with a lifting plate.

[0006] Furthermore, the number of the sliders and the number of the clamping blocks are both two, and a slide groove matched with the slider is opened on the inner side of the placement seat, and the slider can ensure the stability of the left and right movement of the movable rod.

[0007] Furthermore, a support column is fixedly installed on the top of the placement seat, a protection box is fixedly installed on the outside of the support column, the motor is fixedly installed on the inside of the protection box, a movable cover is fixedly installed on the outside of the support column, and a plurality of heat dissipation holes are opened on the inside of the protection box to avoid generating a large amount of heat during the operation of the motor.

[0008] Furthermore, the lifting plate is fixedly mounted on the outside of the movable sleeve, and a limit plate is fixedly mounted on the top of the support column, and the limit plate can limit the distance of the up and down movement of the lifting plate.

[0009] Furthermore, a damper is fixedly installed on the top of the lifting plate, and a support frame is fixedly installed on the top of the damper. There are four dampers, which are convenient for reducing the shaking of the cable during the installation process.

[0011] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0012] The cable laying structure which is easy to adjust starts the motor first, and its output shaft drives the threaded rod to rotate. The rotation of the threaded rod drives the movable rod to move left and right. Then the left and right movement of the movable rod drives the lifting plate to move up and down. The up and down movement of the lifting plate drives the cable inside the fixed cylinder to move up and down, so as to achieve the purpose of facilitating the adjustment of the support height. When the connecting rod slides downward under the action of pressure, the compression spring will be compressed, and the compression spring will also provide a rebound force. Finally, the compression spring will slow down the speed of the connecting rod sliding downward and reduce the impact force. When supporting the cable, it can alleviate the force and speed of the cable when it descends, so as to avoid the cable being damaged due to the impact force, thereby ensuring the progress of the cable laying construction.
