Description

Technical Field

[0001] This utility model belongs to the field of bridge crane auxiliary equipment inspection and maintenance technology, and relates to a bridge crane track beam sliding hanging point device. Background Technology

[0002] Bridge cranes are important tools and equipment for realizing the mechanization and automation of production processes in modern industrial production and lifting and transportation. When the equipment is under maintenance, workers need to perform high-altitude operations on the side of the track beam. Since the track beam of the bridge crane is located at a high position and one side is an open surface, the safety of workers cannot be guaranteed during maintenance operations. At the same time, when working on the open surface of the bridge crane, a cage needs to be used for maintenance operations on the open surface. Moving and changing the attachment points of personnel is cumbersome and poses safety hazards, which increases time costs and safety risks, resulting in low work efficiency. Summary of the Invention

[0003] The technical problem to be solved by this utility model is to provide a sliding hanging point device for bridge crane track beams. The device has sliding flexibility through the cooperation of the trolley shell and the sliding mechanism. When it reaches the working area, the limiting pressure plate is attached to the bridge crane track to fix the device as a whole. The upper U-shaped hanging ring provides a stable hanging point for workers' safety ropes and safety belts, which ensures the safety of workers, improves the convenience of the device, and reduces manual movement time and labor intensity.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a bridge crane track beam sliding hanging point device, which includes a trolley housing, a sliding mechanism, and a limiting pressure plate; multiple sliding mechanisms are connected to the first shaft hole inside the trolley housing through rolling shafts, and the limiting pressure plate is symmetrically connected to both sides of the trolley housing and connected to the ear plate.

[0005] The upper surface of the trolley housing is provided with an inverted U-shaped hanging ring, and ear plates are provided on both sides of the trolley housing. The ear plates are provided with a second shaft hole, and the trolley housing is provided with a first shaft hole symmetrically on both sides.

[0006] The trolley housing has a U-shaped groove structure with the opening facing downwards.

[0007] The sliding mechanism includes a wheel, a rolling shaft, and a bushing; the wheel and the rolling shaft are nested together, and the bushing is nested together with the rolling shaft and connected to one side of the wheel.

[0008] The rolling shaft has shoulders at both ends, and the inner side of the shoulders is connected to one side of the trolley housing.

[0009] The limiting pressure plate includes a fixed pressure plate, a rotating shaft, a shaft tube, a pressure plate positioning block, bolts, and threaded holes; one end of the fixed pressure plate is provided with a shaft tube, the rotating shaft is nested with the shaft tube, the upper end of the shaft tube is provided with a pressure plate positioning block, and the pressure plate positioning block is provided with a threaded hole that is threadedly engaged with the bolt.

[0010] The fixed pressure plate is an arc-shaped flat plate. One end of the fixed pressure plate is connected to the side of the shaft tube, and it is connected to both sides of the frame through a rotating shaft.

[0011] The main beneficial effects of this utility model are as follows:

[0012] By connecting the trolley housing with the sliding mechanism and the limiting pressure plate, the entire device can achieve a sliding effect while also allowing the limiting pressure plate to fit and be fixed to the bridge crane track, thus improving convenience and operator safety.

[0013] The U-shaped hanging ring allows workers and equipment to be lifted and placed on the bridge crane track, while also providing a stable anchor point for personnel working on the free surface.

[0014] The sliding mechanism connects the bushing to the wheel, making it less likely for the wheel to move laterally when rotating, thus preventing it from sliding off the bridge crane track and increasing the stability of the sliding mechanism during movement, making it less prone to shaking.

[0015] The limiting pressure plate's arc-shaped surface fits into the bridge crane's track beam, and the pressure plate's positioning block is parallel to the side of the trolley's housing. Rotating the bolts causes the bolt end face to contact the side of the trolley's housing for fixation, increasing the device's stability, preventing it from tilting or slipping, and ensuring the safety of manual operations.

Detailed Implementation

[0026] like Figures 1-8 A sliding attachment point device for a bridge crane track beam includes a trolley housing 1, sliding mechanisms 2, and limiting pressure plates 3. Multiple sliding mechanisms 2 are connected to the first shaft hole 13 inside the trolley housing 1 via rolling shafts 22. The limiting pressure plates 3 are symmetrically connected to both sides of the trolley housing 1 and connected to ear plates 12. This device provides both sliding effect and stability, serving as a safety rope attachment point and increasing safety.

[0027] Furthermore, the upper surface of the trolley housing 1 is provided with an inverted U-shaped hanging ring 11, and ear plates 12 are provided on both sides of the trolley housing 1. The ear plates 12 are provided with second shaft holes 14, and the trolley housing 1 is symmetrically provided with first shaft holes 13 on both sides. The shaft holes are connected to the rolling shaft 22 to prevent it from shaking during movement, thereby improving the stability of the device during movement.

[0028] Furthermore, the trolley housing 1 has a U-shaped groove structure with the opening facing downwards. This allows the inner side of the device to connect with the sliding mechanism 2 while improving the overall connection effect of the device.

[0029] Furthermore, the sliding mechanism 2 includes a wheel 21, a rolling shaft 22, and a bushing 23; the wheel 21 is nested with the rolling shaft 22, and the bushing 23 is nested with the rolling shaft 22 and connected to one side of the wheel 21. The bushing 23 is connected to the wheel 21 to prevent it from shaking during movement.

[0030] Furthermore, the rolling shaft 22 is provided with shoulders 221 at both ends, and the inner side of the shoulders 221 is connected to one side of the trolley housing 1. The protrusions at both ends of the rolling shaft 22 prevent lateral movement of the sliding mechanism 2 during movement, thereby improving the stability of the movement.

[0031] Furthermore, the limiting pressure plate 3 includes a fixed pressure plate 31, a rotating shaft 32, a shaft tube 33, a pressure plate positioning block 34, a bolt 35, and a threaded hole 36. One end of the fixed pressure plate 31 has a shaft tube 33, and the rotating shaft 32 is nested within the shaft tube 33. The upper end of the shaft tube 33 has a vertically positioned pressure plate positioning block 34, and the pressure plate positioning block 34 has a threaded hole 36 that engages with the bolt 35. In use, by rotating the fixed pressure plate 31, the pressure plate positioning block 34 is made parallel to the trolley housing 1, and the bolt 35 is rotated so that its end face contacts the trolley housing 1 for locking. This reduces the risk of the device tipping over when locked, increasing the overall stability of the device.

[0032] Furthermore, the fixed pressure plate 31 is an arc-shaped flat plate. One end of the fixed pressure plate 31 is connected to the side of the shaft tube 33, and it is connected to both sides of the frame through the rotating shaft 32. This makes the fixed pressure plate 31 and the device a whole, improving the contact effect between the fixed pressure plate 31 and the bridge crane track, and enhancing the safety of the device.

The embodiments and features described in this application can be arbitrarily combined without conflict. The protection scope of this utility model should be defined as the technical solution described in the claims, including equivalent substitutions of the technical features described in the claims. That is, equivalent substitutions and improvements within this scope are also within the protection scope of this utility model.
