[0002] In modern society, power supply is an important foundation for maintaining the normal operation of life and work. And high - altitude wire erection in power construction is an important link in power supply, which involves the layout, installation and maintenance of power lines. In this process, the use of wire - walking pulleys is essential; a wire - walking pulley is a device specifically used for laying power cables. Its main function is to reduce the friction of the cable during the laying process, prevent the cable from being damaged, and at the same time improve the construction efficiency; the usage method of the wire - walking pulley is as follows: First, fix the cable on the wire - releasing pulley, and then pull out the cable through a traction device. During the process of pulling out the cable, the wire - walking pulley will rotate automatically to reduce the friction between the cable and the pulley. When the cable is completely pulled out, the position of the wire - releasing pulley can be adjusted to arrange the cable to the required position.

[0003] Generally, a double - wheel wire - walking pulley is needed for wire erection between relatively high electric towers. The existing double - wheel wire - walking pulleys are usually disassembled into many parts for convenient transportation during transportation and then installed on site, which delays the project progress of on - site construction workers. In view of the above situation, we have introduced an efficient double - wheel wire - walking pulley. Content of the Utility Model

Specific embodiments

[0020] The following will be combined with the attached Figures 1 to 3 The present utility model will be described in detail. The technical solutions in the embodiments of the present utility model are clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0021] The present utility model provides an efficient double-wheel wire-walking pulley through improvement, such as Figures 1 - 3As shown in the figure, it includes two wire laying pulleys 100. The two wire laying pulleys 100 are arranged between two installation mechanisms 200. Each of the two installation mechanisms 200 includes a connecting plate 210, a first limiting plate 220, a second limiting plate 230, and four fixing blocks 240. The top of the connecting plate 210 is connected to the center of the bottom of the first limiting plate 220, and the bottom of the connecting plate 210 is connected to the center of the top of the first limiting plate 220. Baffles 600 are provided on both sides of the top of the two second limiting plates 230. A chute 211 is formed on the surface of the connecting plate 210. The installation mechanism 200 further includes installation shafts 250 inserted through both ends of the inner wall of the chute 211. The other ends of the surfaces of the two installation shafts 250 are respectively inserted and connected to the chutes 211 formed on the surface of another connecting plate 210. The two pulleys are respectively inserted through the centers of the two installation shafts 250. Threads 251 with the same shape but opposite directions are respectively provided on both sides of the two installation shafts 250 located on both sides of the two limiting plates. The eight fixing blocks 240 are respectively inserted through the positions where the threads 251 are formed on the two installation shafts 250. The eight fixing blocks 240 are respectively slidably arranged between the two first limiting plates 220 and the second limiting plates 230.

[0022] In this embodiment: Before transportation, the two installation shafts 250 move towards each other along the chutes 211 formed on the surface of the connecting plate 210, driving the two wire laying pulleys 100 respectively inserted on the two installation shafts 250 to move towards each other. Then, by rotating the two installation shafts 250, the four fixing blocks 240 respectively inserted on the two installation shafts 250 move towards each other in pairs to clamp and fix the connecting plate 210, thereby limiting the installation shafts 250, making the distance between the two wire laying pulleys 100 shorter and reducing the volume for convenient transportation. When arriving at the installation site, rotate the two installation shafts 250 in the reverse direction, driving the four fixing blocks 240 respectively inserted on the two installation shafts 250 to move away from each other in pairs, releasing the limit fixation of the installation shafts 250, resetting the two wire laying pulleys 100, and then by rotating the installation shafts 250, the fixing blocks 240 threadedly connected to both sides of the connecting plate 210 move towards the connecting plate 210 along the first limiting plate 220 and the second limiting plate 230 until they clamp the connecting plate 210 to position and fix the wire laying pulley 100.

[0023] In the above implementation manner, in order to reduce the sliding and dislocation of the cable during the traction process, the following method can be adopted for implementation:

[0024] Reference Figure 1, in a preferred embodiment, mounting seats 400 are provided at both ends of the top of the two first limiting plates 220, and both ends of the bottoms of the two mounting seats 400 are respectively connected to both ends of the top of the two first limiting plates 220. A fixing mechanism 500 is provided at the top of the two mounting seats 400. The fixing mechanism 500 includes two connecting seats 510, two fixing springs 520, two shock-absorbing springs and a fixing seat 530. The two connecting seats 510 are respectively arranged at the tops of the two mounting seats 400. One ends of the two fixing springs 520 are respectively connected to the opposite sides of the two connecting seats 510. The other ends of the two fixing springs 520 are respectively connected to both ends of the bottom of the fixing seat 530. The two shock-absorbing air bags 540 are respectively arranged in the two fixing springs 520. The tops of the two shock-absorbing air bags 540 are respectively connected to both ends of the bottom of the fixing seat 530. The bottoms of the two shock-absorbing air bags 540 are connected to the positions of the two connecting seats 510 close to the fixing springs 520 respectively.

[0025] In this embodiment, during the cable laying process, the traction equipment on the ground pulls the cable through the cable laying pulley 100. The two fixing springs 520 and the shock-absorbing air bags 540 arranged in the fixing springs 520 can provide a force opposite to the movement direction of the cable, offset the pulling force of the ground traction equipment on the cable, ensure the stability of the cable laying pulley 100, reduce the situation of sliding dislocation of the cable during traction, and have a good fixing effect.

[0026] Reference Figures 1 - 3 , in the first embodiment, in order to enable the two mounting shafts 250 to quickly reach both ends of the sliding grooves 211 during installation, reset springs 260 are provided in both sliding grooves 211. When the two mounting shafts 250 are located at both ends of the sliding grooves 211, the reset springs 260 are in a compressed state; during transportation, the two mounting shafts 250 move towards each other along the sliding grooves 211, squeeze the reset springs 260, and then limit and fix the mounting shafts 250. When reaching the construction site, rotate the mounting shafts 250 to release the extrusion of the connecting plate 210 by the fixing blocks 240. The reset springs 260 recover and elongate under their own elastic force, drive the two mounting shafts 250 to quickly reach both ends of the sliding grooves 211, and then limit and fix the mounting shafts 250 again. The operation is convenient and time-saving.

[0027] Reference Figure 1 , in the first embodiment, in order to facilitate the rotation of the mounting shafts 250, mounting handles 300 are provided at one ends of the two mounting shafts 250. By rotating the mounting handles 300, the mounting shafts 250 can be quickly limited and the limit can be released, which is convenient and fast.
