Technical Field:
[0001] The utility model relates to the technical field of power supply maintenance equipment, in particular to an auxiliary installation device for high-voltage cable terminal joints. Background Art:
[0002] When preventive tests and fault maintenance are carried out on high-voltage cable lines, it is necessary to disassemble and assemble the cable terminal joints in the cable chamber. Due to the large weight of the cable itself, it is very inconvenient to rely on manual lifting and moving traditionally. Moreover, the space in the cable trench and the cable chamber is narrow, making it difficult for operators to exert force, resulting in low work efficiency and high labor intensity for personnel. The existing solution is to use a crane or a small hoist for auxiliary operation, but it is necessary to operate under the boom, which is prone to accidents such as boom overturning or traction rope breakage, and there are potential safety hazards. Content of the Utility Model:
[0003] The purpose of the utility model is to provide an auxiliary installation device for high-voltage cable terminal joints to solve the problems existing in the prior art.

A thrust bearing is installed between the top plate and the bottom plate. A support is fixedly provided on the top surface of the top plate, and the support is detachably connected to the cable clamping mechanism through two bolts.
[0006] Further, the cable clamping mechanism includes clamping belts and clamping bolts. Two clamping belts are overlapped. One end of the two clamping belts is detachably connected to the support through a bolt passing through the two clamping belts, and the other ends of the two clamping belts extend out of the rotary support and are provided with two clamping bolts.
[0007] Further, clamping blocks are respectively provided on both sides of the clamping belts at the positions where the clamping bolts are passed through. The two clamping belts are clamped between the two clamping blocks.
[0008] Further, a telescopic leg is hinged on each side of the base. The telescopic leg includes a telescopic rod and a foot. One end of the telescopic rod is hinged to the base, and the other end of the telescopic rod is hinged to a foot.

[0010] Advantages of the present utility model: The electric push rod drives the rotary support and the cable clamping mechanism to move up and down, so that the cable can be lifted and moved, replacing the manual dragging and lifting operations, and reducing the labor intensity. At the same time, it is also provided with telescopic legs with adjustable lengths, which can be set in the cable chamber and cable trench, solving the problem of inconvenient operation in a narrow space.

[0017] Such as Figure 1As shown in the figure, an auxiliary installation device for a high-voltage cable terminal joint includes a base 1, an electric push rod 2, a rotary support 3, and a cable clamping mechanism 4. An electric push rod 2 is vertically and fixedly installed on the base 1. The top of the telescopic end of the electric push rod 2 is fixedly connected to the rotary support 3. The electric push rod 2 can drive the rotary support 3 and the cable clamping mechanism 4 at its top to move up and down. The rotary support 3 includes a bottom plate 301, a thrust bearing 302, a top plate 303, and a support 304. The bottom plate 301 is fixedly connected to the telescopic end of the electric push rod 2. The bottom plate 301 is horizontally arranged. A thrust bearing 302 is installed between the top plate 303 and the bottom plate 301, enabling the top plate 303 to rotate freely in the horizontal plane. A support 304 is fixedly provided on the top surface of the top plate 303. The support 304 is detachably connected to the cable clamping mechanism 4 through two bolts. The support 304 can rotate freely around the axis of the thrust bearing 302, so that the cable clamping mechanism 4 can rotate freely in the horizontal plane, which is convenient for adjusting the position of the cable joint when clamping the cable.
[0018] As Figure 2 shown: The cable clamping mechanism 4 includes clamping strips 401 and clamping bolts 402. Two clamping strips 401 are overlapped. One end of the two clamping strips 401 is detachably connected to the support 304 through a bolt passing through the two clamping strips 401. The other ends of the two clamping strips 401 extend out of the rotary support 3 and are provided with two clamping bolts 402. A cable is to be passed between the two clamping bolts 402 and between the two clamping strips 401. During use, first loosen the two clamping bolts 402, pass the cable between the two clamping strips 401, and then tighten the two clamping bolts 402 respectively to clamp and fix the cable. The clamping strips 401 are made of cloth-based fiber rubber belts, which can generate a large frictional force with the outer skin of the cable and can also resist tearing. When the electric push rod 2 drives the cable clamping mechanism 4 to rise, it can drive the cable to rise upward together.
[0019] At the same time, to ensure that the clamping strips 401 can stably clamp and fix the cable, clamping blocks 403 are respectively provided on both sides of the positions where the clamping bolts 402 are passed through on the clamping strips 401. The two clamping strips 401 are clamped between the two clamping blocks 403. The clamping blocks 403 can increase the contact area between the clamping bolts 402 and the clamping strips 401, reduce the pressure, and prevent the clamping strips 401 from tearing at the openings.
[0020] As Figure 3As shown in the figure: during use, the bottom of the base 1 is placed in the ground of the cable trench or cable chamber. If the ground is uneven, it may tip over during jacking. To enhance the stability of the base 1, a telescopic support leg 5 is hinged on each side of the base 1. The telescopic support leg 5 includes a telescopic rod 501 and a foot 502. One end of the telescopic rod 501 is hinged to the base 1, and the other end of the telescopic rod 501 is hinged with a foot 502. During use, the length and angle of the telescopic support leg 5 can be adjusted according to the on-site terrain, so that the base 1 is stably fixed on the ground.
[0021] During on-site operation, there is usually a partition layer or a large height difference between the cable trench or cable chamber and the power distribution cabinet above. Two separate operations are required. To facilitate remote control of the lifting and lowering of the cable joint by personnel on the power distribution cabinet layer, a wireless control device can be installed. The wireless control device is electrically connected to the electric push rod 2. The wireless control device is an existing control module, such as a Bluetooth or 433 control module, which is divided into a receiving end and a transmitting end. The receiving end is electrically connected to the electric push rod 2 and can send forward and reverse, on-off signals to control the lifting, lowering, starting and stopping of the electric push rod 2. The receiving end communicates with the transmitting end through wireless communication. The transmitting end can control the receiving end to send control signals. Its specific structure and working principle are well-known technologies to those skilled in the art, so they will not be elaborated here.
