Detailed ways

The present application will be further described in detail below in conjunction with Figure 1.

The embodiment of the present application discloses a wire-laying auxiliary device for power cable construction. Referring to Figure 1, an auxiliary device for laying out wires for power cable construction includes a frame 1 fixed vertically on the ground. The frame 1 is arranged in a triangular shape, and a rotating drum 11 is rotatably connected to the frame 1. The rotating drum 11 is The rotation axis is horizontal, and the cables are wound around the drum 11 in an orderly manner along the length direction of the drum 11. The frame 1 is also fixedly connected with a limit plate 12. There are two sets of limit plates 12, and the two sets of limit plates 12 are arranged oppositely. At both ends of the rotating drum 11, the limiting plates 12 limit the cables, and the limiting plates 12 are also provided with a resisting component 2 for stably resisting the cables;

The contact assembly 2 includes a contact rod 21 slidably disposed on the limiting plate 12 and an adjustment member 24 for slidingly adjusting the contact rod 21. The layout direction of the contact rod 21 is parallel to the axis direction of the rotating drum 11, and The sliding direction of the contact rod 21 is consistent with the radial direction of the limiting plate 12, and there is a gap between the contact rod 21 and the drum 11 for the cable to pass through, and the contact rod 21 and the cable are movable and fit.

When unwinding the cable, the technician pulls the end side of the cable to detach the cable from the drum 11, driving the drum 11 to rotate, and the cable passes through the gap between the abutment rod 21 and the drum 11. At this time, the cable comes into contact with the drum 11. The connecting rod 21 is tightly against the cable, so that the uncoiled cable from the drum 11 is not easy to be uncoiled or uncoiled, thereby reducing the subsequent technicians' storage and rewinding operations of the uncoiled cable; at the same time, the adjusting member 24 is provided to abut against The rod 21 is slidably adjusted. After the cable is uncoiled, the thickness of the cable and the drum 11 becomes thinner. The adjusting key slides and adjusts the contact rod 21, thereby stably tightening the cables of different thicknesses, and then unwinding the entire cable. During the process, the unwound cable is kept firmly pressed to improve the stability of the cable being wound on the drum 11.

Referring to Figure 1, in order to further improve the stability of the cable when unwinding, two sets of abutment rods 21 are provided, and the two sets of abutment rods 21 are spaced apart along the circumferential direction of the drum 11, and the two sets of abutment rods 21 are parallel. layout.

Since the thickness of the cable and the drum 11 will become thinner when the cable is being paid out, in order to facilitate stable compression of the cable when the cable is being paid out, a sliding groove 22 is provided on the limiting plate 12, and the sliding groove 22 is provided along the limit. The position plate 12 is opened in the radial direction, and both ends of the abutting rod 21 are fixedly connected with sliding blocks 23. The two sliding blocks 23 correspond to the two sliding grooves 22 one by one. The sliding blocks 23 are slidably arranged on the sliding grooves 22. In the groove 22 , the sliding direction of the sliding block 23 is consistent with the layout direction of the sliding groove 22 .

At the same time, in order to facilitate the adjustment of the sliding block 23, the adjusting member 24 is an adjusting spring 241. One end of the adjusting spring 241 is fixed on the inner wall of the sliding groove 22 close to the axis of the limiting plate 12, and the other end of the adjusting spring 241 is connected to the axis of the limiting plate 12. The side wall of the sliding block 23 close to the axis of the limiting plate 12 is fixedly connected, and the adjusting spring 241 in the initial state is in a stretched state; at the same time, the limiting rod 25 is fixedly connected in the sliding groove 22, and the layout direction of the limiting rod 25 is consistent with the sliding groove 22. The opening direction of the shifting groove 22 is consistent, and the limiting rod 25 penetrates the sliding block 23 and is slidingly adapted to the sliding block 23; therefore, when the cable is not being unwound, under the action of the elastic restoring force of the adjusting spring 241, it abuts The rod 21 always has a tendency to approach the outer peripheral wall of the drum 11, thereby achieving a stable hold on the cable, reducing the loose winding of the cable, and improving the stability of the cable; at the same time, when the cable is being paid out, the cable and the drum 11 At this time, under the elastic restoring force of the adjusting spring 241 of the abutting rod 21, as the thickness of the cable and the drum 11 becomes thinner, the sliding block 23 slides under the elastic restoring force of the adjusting spring 241. It slides in the groove 22, and at the same time, the limiting rod 25 makes the sliding block 23 more stable, and the abutting rod 21 approaches the outer peripheral wall of the rotating drum 11, thereby achieving stable resistance during the entire cable unwinding process, thereby making the Unwinding of cables is unlikely to occur during the unwinding process.

During the cable unwinding process, the abutment rod 21 is in stable contact with the cable. When rotating, the cable and the abutment rod 21 are prone to rigid friction, which reduces the surface quality of the cable. Therefore, in order to improve this problem, the abutment rod 21 is placed close to the cable and the cable is unwound. A contact roller 3 is rotatably connected to the contact rod 21 at one end. The rotation axis of the contact roller 3 is consistent with the length direction of the contact rod 21. A contact pad 33 is fixedly bonded to the upper circumferential side of the contact roller 3. The resistance pad 33 of the present application is one or more of a rubber pad, a sponge pad, and a PVC pad, and the resistance pad 33 fits the end side of the cable being laid out; when the technician pays out the cable, The cable is in contact with the contact roller 3.

At the same time, in order for the contact roller 3 to stably reduce the wear of the cable, a receiving groove 31 is provided on the outer peripheral wall of the contact roller 3. The receiving groove 31 is arranged in an arc shape, and the roller diameter at both ends of the contact roller 3 is larger than that of the contact roller 3. The diameter of the middle part of the roller 3 and the inner wall of the accommodating groove 31 are in contact with the peripheral side of the cable; therefore, during the cable unwinding process, under the limitation of the accommodating groove 31, the cable is always located in the accommodating groove 31 and in contact with the accommodating groove 31. The inner walls of the groove 31 are in tight contact with each other, so that the cable can be laid out stably and be less likely to be scratched and worn.

And since technicians usually wind the cable along the length direction of the drum 11, during the unwinding and unwinding process, the cable at the unwinding end will also move along the length direction of the drum 11, so in order to achieve The contact roller 3 stably limits the cable at one end of the payout. The contact rod 21 is provided with a two-way thread 32, and the pitch of the two-way thread 32 is consistent with the diameter of the cable. The contact roller 3 is threaded and assembled on the contact rod 21 During the cable pay-out process, the cable is in contact with the contact roller 3 and drives the contact roller 3 to rotate. During the cable pay-out process, the cable moves along the length of the drum 11, and the cable simultaneously carries the contact roller 3 with it. The rotation causes the contact roller 3 to move along the length direction of the contact rod 21 to achieve stable limiting and tightening of the cable during the entire unwinding or winding process. The structure is simple and does not require additional operations by technicians.

The implementation principle of the unwinding auxiliary device for power cable construction in the embodiment of the present application is as follows: during the cable unwinding process, the abutment rod 21 stably tightens the uncoiled cable so that the cable is less likely to uncoil, while the other The abutting roller 3 on the abutting rod 21 limits the end side of the cable payout, reducing the rigid friction between the limiting rod 25 and the cable, and at the same time limiting the position of the cable to reduce the cable from being detached from the abutting roller 3. This allows the cable to be laid out stably and facilitates the cable take-up operation after the construction is completed.

The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application shall be covered by the scope of protection of the present application. Inside.
