Description

Technical Field

[0001] The utility model relates to the technical field of overhead line guide devices, in particular to a guide device for an overhead line. Background Art

[0002] Overhead lines refer to transmission lines that are installed on electric poles on the ground. During overhead line construction, workers need to adjust the direction of the line to ensure that the transmission lines are not interfered with by the outside world, thereby ensuring the stability and safety of power transmission. Electric workers usually use fixed pulleys to guide overhead lines.

[0003] When workers use fixed pulleys to guide transmission lines, they mainly use the fixed pulleys to support and steer the transmission lines, thereby achieving the guiding effect. However, when guiding the transmission lines, workers need to pull the transmission lines to ensure that the fixed pulleys can guide the transmission lines. Otherwise, the tension of the transmission lines will disappear and they will not be able to stabilize on the fixed pulleys, which will affect the guiding effect. To this end, we propose a guide device for overhead lines to solve the above problems. Utility Model Content

[0004] The utility model aims to provide a guide device for overhead lines, which solves the problem that when guiding the transmission wire, once the tension of the transmission wire disappears, the fixed pulley cannot stably guide the transmission wire.

[0021] In the description of this utility model, it should be noted that, unless otherwise expressly specified or limited, the terms "installed," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections; direct connections, indirect connections through an intermediate medium, and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on specific circumstances.

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] See also Figure 1-5 In the utility model, a guide device for an overhead line includes an L-shaped plate 1. Two elastic plates 5 are fixedly connected to the bottom surface of the L-shaped plate 1. The side surfaces of the two elastic plates 5 that are close to each other are fixedly connected to an arc plate 6. The elastic plates 5 can be used to adjust the distance between the two arc plates 6, which can be suitable for poles of different thicknesses. The left and right sides of each arc plate 6 are fixedly connected to connecting blocks 7. Each group of connecting blocks 7 is connected by bolts. The connection between the connecting blocks 7 by bolts can stabilize the arc plates 6 on the boom, thereby facilitating the staff to guide the transmission lines.

[0024] A support assembly 2 is installed at the top of the L-shaped plate 1. The support assembly 2 includes a frame plate 201 installed at the top of the L-shaped plate 1. Two support wheels 202 are installed at the top of the frame plate 201. The two support wheels 202 can be used to position the transmission line, making it convenient for staff to change the horizontal angle of the transmission line.

[0025] An angle adjustment assembly 3 is installed on the back of the L-shaped plate 1. The angle adjustment assembly 3 includes a horizontal plate 301 installed on the back of the L-shaped plate 1. Two vertical plates 302 are fixedly connected to the upper surface of the horizontal plate 301. The two vertical plates 302 are connected to a threaded rod 303 on one side close to each other. The threaded rod 303 can be supported and stabilized by the vertical plate 302.

[0026] The outer surface of the threaded rod 303 is threadedly connected to a moving block 304, and the upper surface of the moving block 304 is connected to the bottom surface of the support plate 401. When the threaded rod 303 is rotated, the moving block 304 can move on the threaded rod 303, and the moving block 304 can drive the support plate 401 to move.

[0027] The front end of the threaded rod 303 passes through the vertical plate 302 adjacent thereto and is fixedly connected to a turning handle 307 , which allows a worker to conveniently turn the threaded rod 303 .

[0028] A stabilizing groove 305 is provided on the upper surface of the horizontal plate 301, and a stabilizing block 306 is slidably connected to the inner wall of the stabilizing groove 305. The top of the stabilizing block 306 is connected to the bottom surface of the moving block 304. The cooperation between the stabilizing block 306 and the stabilizing groove 305 can stabilize the moving block 304 and prevent the moving block 304 from deflecting when moving.

[0029] A pulling assembly 4 is installed above the angle adjustment assembly 3. The pulling assembly 4 includes a support plate 401. A motor 402 is installed on the upper surface of the support plate 401. The output end of the motor 402 is fixedly connected to a first guide wheel 403. The motor 402 can drive the first guide wheel 403 to rotate. A second guide wheel 404 is installed on the upper surface of the support plate 401. The first guide wheel 403 and the second guide wheel 404 can be used to clamp the transmission line. When the support plate 401 moves, it will drive the first guide wheel 403 and the second guide wheel 404 to move, and the transmission line will gradually tilt in the horizontal direction, so that the transmission line can be guided at multiple angles.

[0030] Gears 405 are installed on the top of the first guide wheel 403 and the top of the second guide wheel 404. The two gears 405 are engaged with each other. The first guide wheel 403 can drive the two gears 405 to rotate towards each other. At the same time, the first guide wheel 403 and the second guide wheel 404 will rotate towards each other, which will pull the transmission wire and enable the transmission wire to be stabilized on the support wheel 202, the first guide wheel 403 and the second guide wheel 404, thereby ensuring the guiding effect of the transmission wire.

[0031] The working principle of the present invention is as follows: when in use, the L-shaped plate 1 is fixed to the electric pole by using the curved plate 6, and then the transmission wire is first passed between the two support wheels 202, and then passed between the first guide wheel 403 and the second guide wheel 404, and then the threaded rod 303 is rotated, the moving block 304 will move on the threaded rod 303, and at the same time the moving block 304 will drive the support plate 401, and the first guide wheel 403 and the second guide wheel 404 will drive the transmission wire to move, thereby deflecting the transmission wire to a suitable line-laying angle, and finally starting the motor 402 to work, the motor 402 will drive the first guide wheel 403 to rotate, and at the same time the two gears 405 will rotate in opposite directions, and the first guide wheel 403 and the second guide wheel 404 will rotate in opposite directions to pull and transport the transmission wire, and the transmission wire located between the frame plate 201 and the support plate 401 will generate a certain tension, which can make it stable on the support wheel 202, the first guide wheel 403 and the second guide wheel 404, thereby ensuring the effect of guiding the transmission wire.
