[0002] Power cable: It is a cable used to transmit and distribute electrical energy. Power cables are commonly used in urban underground power grids, power station lead-out lines, internal power supply of industrial and mining enterprises, and underwater transmission lines across rivers and seas. In power lines, the proportion of cables is gradually increasing. Currently, cable alignment devices are mostly used to complete the cable core alignment work.

[0003] Jianjingsuo disclosed a copper cable production docking device in the authorization announcement number: CN218732328U, including a box body, a placement opening at one end of the box body, an adjustment component at one end of the placement opening, a fixing component at one side of the adjustment component, a placement plate at the middle of the box body, a first placement block at one end of the placement plate, the first placement block has a conveying opening near both sides of the box body, and a conveying component is provided on one side of the conveying opening, which can avoid the problem of manual winding, and can also ensure work efficiency and adjust cables of different diameters as needed, and can also prevent the cables from being offset, thereby better ensuring the docking effect.

[0004] Although the above solution can ensure work efficiency and adjust cables of different diameters as needed, and can also prevent cable deviation, the length of the cable needs to be constantly adjusted during the docking process, which results in low work efficiency. Therefore, we propose a docking device for power cables. Utility Model Content

[0005] The main purpose of the utility model is to provide a docking device for power cables, which solves the problem of low work efficiency due to the need to constantly adjust the length of the cables during the docking process by providing an adjusting unit and a fixing unit.

[0006] To achieve the above objectives, the present invention provides the following technical solutions:

[0007] A power cable docking device comprises a main body unit, an adjustment unit arranged in the main body unit, a fixing unit arranged above the adjustment unit, and a covering unit arranged on the side of the main body unit;

[0008] The adjustment unit includes a hydraulic telescopic rod mounted on the bottom wall of the main unit, a fixed seat mounted on the telescopic end of the hydraulic telescopic rod, a threaded shaft movably arranged inside the fixed seat and having two sections of threads with opposite rotation directions, a moving member mounted on the side surface of the threaded shaft, and a drive motor mounted on the input end of the threaded shaft;

[0009] The fixing unit includes a U-shaped seat installed on the top of the moving member, an arc-shaped support plate installed on the inner bottom wall of the U-shaped seat, and a clamping member arranged inside the U-shaped seat and above the arc-shaped support plate.

[0010] Preferably, the main body unit includes a box body, and locking universal wheels installed at the bottom of the box body.

[0011] Preferably, the box body further includes a traveling handrail installed on the side wall of the box body.

[0012] Preferably, the adjusting unit further includes a limit washer installed on the inner side wall of the fixed seat, and the limit washer is sleeved on the peripheral side of the threaded shaft.

[0013] Preferably, the clamping member includes a moving through hole opened at the top of the U-shaped seat, a moving rod movably penetrating and arranged in the moving through hole, an arc-shaped clamping plate installed at the bottom of the moving rod, a stretching plate installed at the top of the moving rod, and a connecting spring sleeved on the peripheral side of the moving rod and fixedly connected to the arc-shaped clamping plate at one end and the inner bottom wall of the U-shaped seat at the other end.

[0014] Preferably, there are two sets of overall structures composed of the moving member and the fixing unit, and the two sets of overall structures composed of the moving member and the fixing unit are symmetrically arranged with respect to the bisecting plane of the threaded shaft.

[0015] Preferably, the covering unit includes a U-shaped seat installed on the side wall of the box body, a covering plate movably installed in the U-shaped seat, and an opening and closing handle installed on the covering plate.

[0016] Compared with the prior art, the utility model has the following beneficial effects:

[0017] In the utility model, through the arranged adjusting unit and fixing unit, when clamping is required before cable docking, first pull up the stretching plate, so that the moving rod drives the arc-shaped clamping plate to move upward and compresses the connecting spring. Until after the cable is placed inside the arc-shaped support plate, the force applied to the stretching plate is removed. Under the elastic force of the connecting spring, the arc-shaped clamping plate stops after fitting with the side wall of the cable, thus realizing stable clamping of cables with different specifications and thicknesses; when the clamping of the cable is completed, the driving motor drives the threaded shaft to rotate. Due to the threads with opposite helix directions at both ends opened on the threaded shaft, the moving member can drive the cables in the two U-shaped seats to approach each other until they stop after the ends contact, thus realizing convenient docking of the cables, avoiding the length adjustment of the cables, and improving the work efficiency.
