Description

Technical Field

[0001] The utility model belongs to the technical field of electric power construction, and particularly relates to a nylon pulley for installing iron tower electric power lines. Background Technique

[0002] With the development of the national economy, the national power grid system has been relatively mature, and there are more and more cases where newly built transmission lines cross existing lines. During the construction process, after using an unmanned aerial vehicle to set up a traction rope, it is also necessary to use a nylon pulley to assist in installing an insulating protection net and cables. Since the nylon pulley has insulation properties, it can move safely along the cable.

[0003] However, since the nylon pulley needs to assist in cable installation, in order to reduce the pressure exerted by the cable on it, the overall length of the pulley is generally designed to be longer. At present, the vast majority of nylon pulleys have a fixed length, which makes it necessary to use a large truck during transportation, not only increasing the transportation cost, but also in some relatively remote areas, due to the uneven road quality, large trucks may not be able to transport the nylon pulley to the designated location.

[0004] Therefore, we propose a nylon pulley for installing iron tower electric power lines to solve the above problems. Content of the Utility Model

[0005] The purpose of the utility model is to solve the problem that the fixed nylon pulley in the prior art is not convenient for transportation, and a nylon pulley for installing iron tower electric power lines is proposed.

[0006] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0007] A nylon pulley for installing iron tower electric power lines, comprising a pulley body, the pulley body includes a central rod, two rotating plates, two fixing plates and two pulley components. The two fixing plates are respectively fixedly connected to the bottoms of the two pulley components, the two rotating plates are respectively hinged to the two fixing plates, the central rod is fixedly arranged between the two rotating plates, a first clamping rod is fixedly arranged on the side wall of the fixing plate facing the hinged position, a second clamping rod is fixedly arranged on the side wall of the fixing plate facing away from the hinged position, a through hole is opened in the side wall of the rotating plate, and a limiting mechanism for fixing the rotating plate is arranged in the through hole.

[0008] Preferably, a rotating sleeve rod is movably sleeved outside the central rod, and the rotating sleeve rod is made of insulating material.

[0009] Preferably, the longitudinal section of the first clamping rod is in the shape of "L", a first clamping groove is opened at the top of the vertical end of the first clamping rod, and the side of the first clamping rod facing away from the hinged position is arc-shaped.

[0011] Preferably, the limiting mechanism includes a block, a spring and two movement rods, movement holes are respectively opened on the side walls on both sides of the through hole, the two movement rods are respectively abutted against the inner walls of the two movement holes, the two movement rods are respectively fixedly connected to the side walls on both sides of the block, the block is abutted against the inner wall of the second slot, one end of the spring is fixedly connected to the bottom wall of the through hole, and the other end is fixedly connected to the bottom wall of the block.

DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0020] like Figure 1 and Figure 2 As shown, a nylon pulley for installing an iron tower power line includes a pulley body, the pulley body includes a center rod 1, two rotating plates 2, two fixed plates 3 and two pulley components 4, the two fixed plates 3 are respectively fixedly connected to the bottom of the two pulley components 4, the pulley components 4 are an indispensable component of the nylon pulley, and therefore the detailed structure is not repeated, the two rotating plates 2 are respectively hinged to the two fixed plates 3, the center rod 1 is fixedly arranged between the two rotating plates 2, a rotating sleeve rod 8 is movably sleeved outside the center rod 1, and the rotating sleeve rod 8 is made of insulating material. The insulating material can protect the safety of the pulley body during the cable laying process, and the rotating sleeve rod 8 can ensure that the cables can pass through the pulley body more smoothly during the cable laying process.

[0021] A first clamping rod 5 is fixedly installed on the side wall of the fixed plate 3 facing the hinged position. The longitudinal section of the first clamping rod 5 is "L"-shaped. A first clamping groove 9 is opened at the top of the vertical end of the first clamping rod 5. The bottom of the first clamping groove 9 is also arc-shaped in order to better cooperate with the clamping block 11. The first clamping rod 5 is arc-shaped on the side facing away from the hinged position.

[0022] A second clamping rod 6 is fixedly installed on the side wall of the fixed plate 3 facing away from the hinged position. The longitudinal section of the second clamping rod 6 is a "U" shape with an opening facing the left, that is, the opening faces the hinged position of the fixed plate 3 and the rotating plate 2. One end of the second clamping rod 6 is fixedly connected to the side wall of the fixed plate 3, and the other end extends into the through hole 7. A second clamping groove 10 is provided on the side wall of the second clamping rod 6 facing the bottom wall of the through hole 7. The opening directions of the first clamping groove 9 and the second clamping groove 10 are different, but the sizes are the same. The opening of the first clamping groove 9 faces upward, and the opening of the second clamping groove 10 faces downward. The other parts are exactly the same. The top of the second clamping groove 10 is an arc-shaped design, and the side wall of the second clamping rod 6 facing the rotating plate 2 is an arc-shaped design.

[0023] Reference Figure 3 , a through hole 7 is provided on the side wall of the rotating plate 2, and the length and width of the through hole 7 are both located between the first clamping rod 5 and the second clamping rod 6, so that both the first clamping rod 5 and the second clamping rod 6 can easily pass through the through hole 7, and a limiting mechanism for fixing the rotating plate 2 is installed in the through hole 7, and the limiting mechanism includes a clamping block 11, a spring 12 and two movement rods 13, and movement holes 14 are provided on the side walls of the through hole 7 on both sides, and the two movement rods 13 are respectively against the inner walls of the two movement holes 14, and the two movement rods 13 are respectively fixedly connected to the side walls of the clamping block 11 on both sides. The clamping block 11 is against the inner wall of the second clamping groove 10, and both sides of the top of the clamping block 11 are arc-shaped. The size of the clamping block 11 is consistent with the size of the first clamping groove 9 and the second clamping groove 10. One end of the spring 12 is fixedly connected to the bottom wall of the through hole 7, and the other end is fixedly connected to the bottom wall of the clamping block 11. The force applied by the spring 12 to the clamping block 11 will make the clamping block 11 always have a force away from the bottom wall of the through hole 7.

[0024] The working principle is as follows: The trolley body is in a folded state during transportation. After reaching the designated position, the staff can slide the moving rod 13 along the moving hole 14, so that the clamping block 11 disengages from the first clamping groove 9. At the same time, this operation is performed on both ends of the rotating plate 2, so that the rotating plate 2 can be disengaged from the restriction of the first clamping rod 5. Then, the rotating plate 2 can be rotated to the vertical state. At this time, the second clamping rod 6 will be inserted into the through hole 7. Due to the arc design at the top of the clamping block 11 and the arc design in front of the second clamping rod 6, the second clamping rod 6 will squeeze the clamping block 11 downward. Then, under the action of the spring 12, the clamping block 11 will be stuck into the second clamping groove 10 of the second clamping rod 6, thereby fixing the position of the rotating plate 2. At this time, the staff can use the trolley body to carry out the work of erecting cables.

[0025] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
