Description

Technical Field

[0001] The utility model belongs to the technical field of power cable traction equipment, in particular to a power cable installation traction device. Background Art

[0002] When installing and laying power cables, it is difficult to move the cables manually due to the length of the cables and their own materials. Or, during the laying process, the cables pass through multiple obstacles, which increases the resistance to the movement of the cables. However, they can withstand short-term pulling by human power, but they cannot withstand long-term pulling by human power. Even if the cables are pulled relatively easily, they cannot withstand long-term pulling by human power.

[0003] The position of the current traction equipment drive wheel is locked and cannot be adjusted. However, in actual applications, when encountering special positions or narrow positions, the drive wheel needs to be adjusted to complete the traction work, and small traction parts need to be replaced;

[0004] On the other hand, it is easy to cause derailment during traction;

[0005] Therefore, the utility model designs a power cable installation and traction device to solve the technical problems existing in the prior art. Utility Model Content

[0009] A fixed bracket is arranged on the support plate, an adjusting bracket is slidably arranged on the fixed bracket, the adjusting bracket is driven by a power device, and a second roller is rotatably connected to the adjusting bracket.

[0010] Preferably, the two groups of movable brackets are provided with a first sliding groove, the first sliding grooves are slidably connected with a first sliding block, the two groups of first sliding blocks are rotatably connected with a first roller, and the first sliding blocks and the first sliding grooves are provided with an array of springs.

DETAILED DESCRIPTION

[0020] The above and other technical contents, features and functions of the present invention are described in detail below with reference to the attached Figure 1-3 The detailed description of the embodiments will clearly show that the structural contents mentioned in the following embodiments are all based on the drawings in the specification.

[0021] Various exemplary embodiments of the present utility model will be described below with reference to the accompanying drawings.

[0022] Embodiment 1, a power cable installation and traction device, comprising a support plate 1 and a bidirectional telescopic rod 2, characterized in that:

[0023] A bidirectional telescopic rod 2 is provided at the bottom of the support plate 1, two groups of mobile brackets 3 are slidably connected to the support plate 1, the two groups of mobile brackets 3 are fixedly connected to the output ends of the bidirectional telescopic rod 2, and the two groups of mobile brackets 3 are provided with first rollers 4;

[0024] The support plate 1 is provided with a fixed bracket 5, and an adjusting bracket 6 is slidably provided on the fixed bracket 5. The adjusting bracket 6 is driven by a power device, and a second roller 7 is rotatably connected to the adjusting bracket 6.

[0025] The power device comprises a one-way telescopic rod 12 provided on a fixed bracket 5, and the output end of the one-way telescopic rod 12 is fixedly connected to the adjustment bracket 6;

[0026] A base 13 is provided at the bottom of the support plate 1 , and an anti-slip pad is provided on the base 13 .

[0027] When in use, during traction, the cable is passed between one set of first rollers 4 and the auxiliary roller 11, bypasses the second roller 7, passes between another set of first rollers 4 and the auxiliary roller 11, and is connected to the take-up assembly;

[0028] If the cable is loose or too tight, the one-way telescopic rod 12 is adjusted to make the adjustment bracket 6 move downward or upward along the fixed bracket 5, driving the second roller 7 to move downward or upward, so as to adjust the cable to be tightened, thereby avoiding derailment caused by looseness or excessive friction caused by the cable being too tight, thereby damaging the roller;

[0029] If the positions of the two groups of first rollers 4 need to be adjusted, the two groups of movable brackets 3 can be driven to move by starting the two-way telescopic rod 2, thereby realizing the adjustment function and improving the use range of the equipment.

[0030] Embodiment 2, on the basis of embodiment 1, the two groups of movable brackets 3 are provided with first sliding grooves 8, the first sliding grooves 8 are slidably connected with first sliding blocks 9, the two groups of first sliding blocks 9 are rotatably connected with first rollers 4, and the first sliding blocks 9 and the first sliding grooves 8 are provided with arrays of springs 10;

[0031] When in use, since an auxiliary roller 11 is provided at the bottom of the movable bracket 3, the cable passes between the first roller 4 and the auxiliary roller 11. Under the action of the auxiliary roller 11, the friction force is further reduced, thereby improving the smoothness of the retracting and releasing of the cable;

[0032] When the cable is retracted or released, since the array of springs 10 is disposed in the first sliding block 9 and the first sliding groove 8 , the first roller 4 can be tightly fitted to the cable under the action of the array of springs 10 .

[0033] The above description is only for illustrating the present invention, and it should be understood that the present invention is not limited to the above embodiments, and various variations that conform to the concept of the present invention are within the protection scope of the present invention.
