Description

Technical Field

[0001] This utility model relates to the field of bridge cranes, and more specifically, to a track cleaning mechanism for bridge cranes. Background Technology

[0002] Bridge cranes, also known as "bridge cranes," are lifting equipment that spans across workshops, warehouses, and material yards for material handling. The bridge frame is directly supported at both ends by elevated rails via a running device. Bridge cranes are available in single-trolley and double-trolley types, and consist of a bridge frame, lifting trolley, trolley traveling mechanism, and electrical equipment. Their ends rest on tall concrete pillars or metal supports, resembling a bridge. The bridge frame is a combination of box-section main beams and end beams, running longitudinally along rails laid on elevated structures on both sides. This allows for full utilization of the space beneath the bridge frame for material handling, without obstruction from ground equipment.

[0003] During operation, dust and impurities accumulate on the rails of bridge cranes, requiring regular cleaning. Currently, most cleaning is done manually, but the concave sides of the rails make manual cleaning inconvenient, resulting in low efficiency and high labor costs. Therefore, we propose an improved rail cleaning mechanism for bridge cranes. Utility Model Content

[0004] The purpose of this utility model is to address the issue that dust and impurities accumulate on the rails of existing bridge cranes during use, requiring regular cleaning. Currently, most of these cleanings are done manually, but the sides of the rails are concave, making manual cleaning inconvenient, inefficient, and labor-intensive.

[0005] To achieve the above-mentioned objectives, this utility model provides the following technical solution:

[0006] A track cleaning mechanism for bridge cranes is proposed to improve the aforementioned problems.

[0007] The application is as follows:

[0008] The device includes a mounting box with two rotatably connected wheels inside. A drive assembly is mounted on the mounting box. Mounting brackets are fixedly mounted on both side walls of the mounting box. A first motor is fixedly mounted on the side wall of each mounting bracket. A first bidirectional screw is fixedly mounted on the output end of the first motor. A U-shaped bracket is threaded onto the first bidirectional screw. A socket is fixedly mounted on the bottom of the U-shaped bracket, and a limit guide block is inserted into the socket. A connecting plate is fixedly mounted on the front of the mounting box. A U-shaped seat is fixedly mounted on the bottom of the connecting plate. A second motor is fixedly mounted on the side wall of the U-shaped seat. A second bidirectional screw is fixedly mounted on the output end of the second motor. An L-shaped bracket is threaded onto the second bidirectional screw, and a cleaning assembly is mounted on the L-shaped bracket.

[0009] As a preferred technical solution of this application, the drive assembly includes a third motor fixedly mounted on the mounting box, a first synchronous pulley fixedly mounted on the output end of the third motor, a second synchronous pulley fixedly mounted in the middle of the two moving pulleys, and the second synchronous pulley and the first synchronous pulley are connected by a synchronous belt.

[0010] As a preferred technical solution of this application, the cleaning component includes a fourth motor fixedly mounted on an L-shaped frame, and the output end of the fourth motor is connected to a cleaning brush.

[0014] As a preferred technical solution of this application, the U-shaped frame is slidably connected to the bottom of the mounting bracket via a slider, and the L-shaped frame is slidably connected to the bottom of the U-shaped base via a slider.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] In the scheme of this application:

[0017] 1. By using adjustable and replaceable limit guide blocks and cleaning brushes, the width of this cleaning device can be freely adjusted, enabling it to clean tracks of different sizes and adapt to various bridge crane tracks, thus making it more widely used.

[0018] 2. The first synchronous pulley is driven to rotate by the third motor, and the first synchronous pulley drives the second synchronous pulley to rotate via the synchronous belt. The second synchronous pulley drives the double moving pulley to rotate, and the double moving pulley rolls on the track, causing the cleaning mechanism to move and clean the inside of the track side wall. This achieves specialized cleaning of the track side wall and solves the problem in the prior art that the sides of the track are concave, making it inconvenient for manual cleaning, which is not only inefficient but also labor-intensive.

A first bidirectional screw 5 is fixedly mounted on the output end of the first motor 4. The first motor 4 drives the first bidirectional screw 5 to rotate. A U-shaped frame 6 is threadedly connected to the first bidirectional screw 5. The rotation of the first bidirectional screw 5 drives the U-shaped frame 6 to move. A socket 7 is fixedly mounted at the bottom of the U-shaped frame 6. The U-shaped frame 6 drives the socket 7. A limit guide block 8 is inserted into the socket 7. The socket 7 drives the limit guide block 8 to move, causing the limit guide block... 8 is located inside the side wall of the track to prevent the device from shifting when moving; a connecting plate 9 is fixedly installed on the front of the mounting box 1, a U-shaped seat 10 is fixedly installed on the bottom of the connecting plate 9, a second motor 11 is fixedly installed on the side wall of the U-shaped seat 10, a second bidirectional screw 12 is fixedly installed on the output end of the second motor 11, the second motor 11 drives the second bidirectional screw 12 to rotate, an L-shaped frame 13 is threadedly connected to the second bidirectional screw 12, the rotation of the second bidirectional screw 12 drives the L-shaped frame 13 to move, a cleaning component is provided on the L-shaped frame 13, the L-shaped frame 13 drives the cleaning component, so that the track side wall is cleaned, and the width is freely adjustable, which can clean tracks of different sizes, and is compatible with various bridge crane tracks, making it more widely used.

[0036] The drive assembly includes a third motor 20 fixedly mounted on the mounting box 1. A first synchronous pulley 21 is fixedly mounted on the output end of the third motor 20. The third motor 20 drives the first synchronous pulley 21 to rotate. A second synchronous pulley 22 is fixedly mounted in the middle of the double moving wheels 2. The second synchronous pulley 22 is connected to the first synchronous pulley 21 by a synchronous belt 23. The first synchronous pulley 21 drives the second synchronous pulley 22 to rotate through the synchronous belt 23. The second synchronous pulley 22 drives the double moving wheels 2 to rotate, and the double moving wheels 2 roll on the track.

[0037] The cleaning assembly includes a fourth motor 14 fixedly mounted on an L-shaped frame 13. The output end of the fourth motor 14 is connected to a cleaning brush 15. A threaded rod 16 is fixedly mounted on the output end of the fourth motor 14. The fourth motor 14 drives the threaded rod 16 to rotate. The cleaning brush 15 is threadedly connected to the threaded rod 16. The rotation of the threaded rod 16 drives the cleaning brush 15 to rotate.

[0038] A slot 18 is provided on the socket 7, and a plug 19 is fixedly installed on the back of the limiting guide block 8. Remove the limiting guide block 8 so that the plug 19 is disengaged from the slot 18, and then replace it with a limiting guide block 8 of appropriate size.

[0039] Specifically, when using the track cleaning mechanism of this bridge crane: place the cleaning mechanism on the bridge crane track, ensuring the double moving wheels 2 are on the track. Then, start the first motor 4, which drives the first bidirectional screw 5 to rotate. The rotation of the first bidirectional screw 5 moves the U-shaped frame 6, which in turn moves the socket 7. The socket 7 then moves the limiting guide block 8, positioning the limiting guide block 8 within the track sidewall to prevent the device from shifting during movement.

[0040] Then, the second motor 11 is started, driving the second bidirectional screw 12 to rotate. The rotation of the second bidirectional screw 12 drives the L-shaped frame 13 to move. The L-shaped frame 13 drives the cleaning brush 15 below, so that the cleaning brush 15 is located inside the side wall of the track. Next, the fourth motor 14 is started, driving the threaded rod 16 to rotate. The rotation of the threaded rod 16 drives the cleaning brush 15 to rotate (the direction of rotation of the threaded rod 16 and the cleaning brush 15 when they are threadedly connected is opposite to the direction of rotation of the threaded rod 16 driven by the fourth motor 14).

[0041] Next, the third motor 20 is started, which drives the first synchronous pulley 21 to rotate. The first synchronous pulley 21 drives the second synchronous pulley 22 to rotate through the synchronous belt 23. The second synchronous pulley 22 drives the double moving wheels 2 to rotate. The double moving wheels 2 then roll on the track, causing the cleaning mechanism to move and clean the inside of the track side wall.

[0042] When the width of this cleaning mechanism needs to be adjusted, remove the cleaning brush 15 and replace it with a cleaning brush 15 of the appropriate size. Then remove the bolts on the side wall of the socket 7, and then remove the limit guide block 8 to disengage the plug 19 from the slot 18. Finally, replace the limit guide block 8 with one of the appropriate size.

[0043] All technical features in this embodiment can be freely combined according to actual needs.

[0044] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
