Description

Technical Field

[0001] This utility model relates to the field of wire transmission technology, specifically to a stop mechanism for a wire-laying pulley. Background Technology

[0002] A cable laying pulley (also known as a cable laying device or pulley) is a device used for laying cables or wires, typically for installing or maintaining power lines, communication lines, oil pipelines, etc. It helps guide and adjust the laying of cables, reduces friction and wear, and improves work efficiency.

[0003] The stopping mechanism of a line-feeding pulley is a safety device, usually used to prevent the pulley from accidentally sliding or falling off during use. Most commonly used stopping mechanisms for line-feeding pulleys are mechanical locks, which fix the position of the line-feeding pulley by inserting a pin into the corresponding pin hole after the line-feeding pulley moves to the required position. However, this method makes it impossible to pull out the pin, requiring manual removal, which is time-consuming and laborious. Some methods use electromagnetic locking, which solves the problem of manual pin removal, but the stability of electromagnetic locking is easily affected by the external environment, thus having certain shortcomings.

[0004] In conclusion, it is necessary to invent a stopping mechanism for a line-feeding pulley. Utility Model Content

[0005] Therefore, this utility model provides a stop mechanism for a line-feeding pulley to solve the problem that this method would prevent the device from pulling out the pin, resulting in the need for manual removal of the pin, which is time-consuming and laborious.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a stop mechanism for a line-feeding pulley, comprising a horizontal plate, side plates fixed on both sides of the bottom of the outer wall of the horizontal plate, a connecting shaft rotatably connected to the inner wall of the side plates, pulleys for line feeding rotatably connected to both sides of the outer wall of the connecting shaft, and a stop component provided at the top of the outer wall of the horizontal plate and above the connecting shaft.

[0007] Preferably, a bearing seat is provided on the inner wall side of the cross plate and at the position corresponding to the connecting shaft, and the outer wall side of the connecting shaft is connected to the bearing seat.

[0008] Preferably, a hook is fixed at the center of the top of the outer wall of the horizontal plate, and auxiliary wheels are provided on both sides of the outer wall of the horizontal plate, with the side ends of the auxiliary wheels fixed to both ends of the connecting shaft.

[0009] Preferably, the stop component includes an electrically controlled push rod, which is fixed to the bottom of the outer wall of the horizontal plate and located above the connecting shaft. An electrical control box is provided at the bottom of the outer wall of the horizontal plate and on one side of the electrically controlled push rod.

[0010] Preferably, an upper pressure plate is fixed to the bottom output end of the electrically controlled push rod, and a bottom pressure plate is provided below the bottom end of the outer wall of the upper pressure plate. The bottom corners of the outer wall of the upper pressure plate are fixedly connected to the corresponding positions of the top end of the outer wall of the bottom pressure plate by elastic telescopic rods.

[0011] Preferably, an electromagnet is fixed at the center of the bottom of the outer wall of the upper pressure plate, and an iron plate is fixed at the top of the outer wall of the bottom pressure plate at a position corresponding to the electromagnet. The electromagnet and the iron plate are magnetically connected.

[0012] Preferably, an arc-shaped locking block is provided below the outer wall of the bottom pressure plate, and the bottom end of the outer wall of the bottom pressure plate and the arc-shaped locking block are fixedly connected by a fixing block.

[0013] Preferably, the top of the outer wall of the connecting shaft is fixed with an anti-slip layer, and the bottom of the inner wall of the arc-shaped block abuts against the outer wall of the anti-slip layer.

[0014] The beneficial effects of this utility model are:

[0015] In this invention, an electrically controlled push rod and an electrically controlled box are installed at the top of the outer wall of the horizontal plate. By controlling the extension of the electrically controlled push rod, the arc-shaped locking block moves downward and locks against the outer wall of the connecting shaft. This prevents the connecting shaft from rotating, thereby fixing the position of the wire feeding trolley. The cooperation between the electrically controlled push rod and the arc-shaped locking block allows personnel to easily fix or loosen the connecting shaft while ensuring the fixing strength of the connecting shaft, preventing the wire feeding trolley from slipping after fixing.

Detailed Implementation

[0021] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0022] See attached document Figures 1-4 This utility model provides a stop mechanism for a line-laying pulley, comprising a horizontal plate 100, with side plates 110 fixed to both sides of the bottom end of the outer wall of the horizontal plate 100. A connecting shaft 200 is rotatably connected to the inner wall of the side plates 110, and pulleys 120 for line laying are rotatably connected to both sides of the outer wall of the connecting shaft 200. The inner wall of the pulleys 120 is connected to the outer wall of the connecting shaft 200 via bearings. Axles are provided at the inner side ends of the horizontal plate 100 and at positions corresponding to the connecting shaft 200. The outer wall side of the bearing seat and the connecting shaft 200 are both connected to the bearing seat. A hook 130 is fixed at the center of the top of the outer wall of the horizontal plate 100. Auxiliary wheels 140 are provided on both sides of the outer wall of the horizontal plate 100. The side ends of the auxiliary wheels 140 are fixed to both ends of the connecting shaft 200. The side plate 110 can move on the tower through the auxiliary wheels 140. The auxiliary wheels 140 can be mechanically fixed by fixing the connecting shaft 200, so that the side plate 110 can be fixed at a suitable position on the tower.

[0023] A stop component is provided at the top of the outer wall of the horizontal plate 100 and above the connecting shaft 200. The stop component includes an electrically controlled push rod 300, which is fixed to the bottom of the outer wall of the horizontal plate 100 and above the connecting shaft 200. An electrical control box 310 is provided at the bottom of the outer wall of the horizontal plate 100 and to one side of the electrically controlled push rod 300. The electrical control box 310 can control the operation of the electrically controlled push rod 300 and the electromagnet 321. An upper pressure plate is fixed to the bottom output end of the electrically controlled push rod 300. 320. A bottom pressure plate 330 is provided below the bottom edge of the outer wall of the upper pressure plate 320. The bottom corners of the outer wall of the upper pressure plate 320 are fixedly connected to the corresponding positions of the top edge of the outer wall of the bottom pressure plate 330 via elastic telescopic rods 350. The elastic telescopic rods 350 can connect the upper pressure plate 320 and the bottom pressure plate 330, and can also shorten the distance between the upper pressure plate 320 and the bottom pressure plate 330 when needed. An electromagnet 321 is fixed at the center of the bottom edge of the outer wall of the upper pressure plate 320. Iron plates are fixed to the top of the outer wall of the bottom pressure plate 330 and at positions corresponding to the electromagnet 321. The electromagnet 321 is magnetically connected to the iron plates. When the electromagnet 321 contacts the iron plates, a person can energize the electromagnet 321 to make it magnetically fixed to the iron plates. This can fix the electric push rod 300 to the arc-shaped locking block 340. An arc-shaped locking block 340 is provided at the bottom of the outer wall of the bottom pressure plate 330. The bottom end of the outer wall of the bottom pressure plate 330 and the arc-shaped locking block 340 are fixedly connected by a fixing block. The top of the outer wall of the connecting shaft 200 is fixed with an anti-slip layer 210. The bottom of the inner wall of the arc-shaped block 340 abuts against the outer wall of the anti-slip layer 210. The arc-shaped block 340 can abut against the outer wall of the connecting shaft 200. The anti-slip layer 210 can improve the fixing effect with the outer wall of the arc-shaped block 340, thus preventing the connecting shaft 200 from rotating and fixing the position of the wire feeding trolley. The anti-slip layer 210 can be a high-friction coating, such as a polyurethane coating.

[0024] The usage process of this utility model is as follows: Those skilled in the art can assemble the device according to the above description, then connect all electrical equipment to an external power supply and connect the control box 310 to facilitate personnel operation. After completion, personnel can use the pulley 120 to lay the wire. When it is necessary to fix the position of the wire laying trolley, personnel can control the control box 310, causing the control box 310 to control the output end of the electric control push rod 300 to extend, so that the upper pressure plate 320 can drive the bottom pressure plate 330 and the arc-shaped locking block 340 to move downwards, causing the arc-shaped locking block 340 to... The 40 abuts against the top of the outer wall of the connecting shaft 200. As the electric push rod 300 extends, the elastic telescopic rod 350 retracts, allowing the electromagnet 321 to move downwards and abut against the iron plate. When the electromagnet 321 contacts the iron plate, the pre-energized electromagnet 321 can magnetically attract and fix itself to the iron plate. This fixes the electric push rod 300 and the arc-shaped locking block 340, thereby restricting the connecting shaft 200 and preventing the connecting shaft 200 and the auxiliary wheel 140 from rotating. This fixes the position of the wire feeding trolley and prevents it from moving.

[0025] The above description is merely a preferred embodiment of this utility model. Any person skilled in the art may modify this utility model or modify it into an equivalent technical solution using the technical solutions described above. Therefore, any simple modifications or equivalent substitutions made based on the technical solutions of this utility model are within the scope of protection claimed by this utility model.
