Description

Technical Field

[0001] This utility model relates to the field of safety devices for lifting equipment, and in particular to a track cleaner for cranes. Background Technology

[0002] According to the relevant requirements of TSG 51—2023 "Safety Technical Specifications for Special Equipment", when the crane's trolley and crane move to the vicinity of the track end, firstly, the safety impact ruler will collide with the limit switch to cut off the power; secondly, the buffer will collide with the track beam end to stop and decelerate; finally, the wheels will collide with the crescent-shaped stop at the track end to stop and prevent the crane from derailing. Traditional track sweepers have the following technical defects: 1. A straight crossbar structure is adopted, which directly collides with the crescent-shaped stop when the equipment runs to the end of the track; 2. Collisions and impacts can cause the sweeper to deform and malfunction, requiring frequent replacements and increasing labor and material costs; 3. The existing structure cannot effectively avoid the crescent-shaped stop, affecting the normal operation of the equipment; 4. High maintenance costs and long downtime for repairs.

[0003] Currently, most sweepers widely used in the domestic crane industry are integral welded structures, lacking flexible adjustment or avoidance designs, and cannot adapt to end-stop collision conditions. Although some improvement schemes have attempted to optimize the structure, they have still failed to solve the problem of rigid collision with the crescent-shaped stop.

[0004] Therefore, there is an urgent need to develop a new type of track cleaning device that can effectively remove track debris and automatically avoid crescent-shaped stops when approaching the end, thereby improving equipment reliability and operational safety, reducing maintenance costs and downtime, and meeting the safety requirements of special equipment. Utility Model Content

[0005] This utility model provides a track cleaner for cranes, which solves the problem of frequent damage to traditional cleaners through a concave crossbar design.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A track cleaner for cranes includes a vertical angle steel fixed to the end of the end beam of the crane track cleaner and a horizontal angle steel connected to the vertical angle steel. The horizontal angle steel has a concave structure to accommodate a crescent-shaped stop at the end of the track. The inner dimension of the concave horizontal angle steel is 20mm larger than the maximum outer dimension of the crescent-shaped stop, so that when the crane track cleaner runs to the end of the track, a 50mm longitudinal safety gap is formed between the horizontal angle steel and the crescent-shaped stop to avoid direct collision.

[0007] Furthermore, the vertical angle steel is fixed to the end of the end beam with high-strength bolts, and the horizontal angle steel and the vertical angle steel are fully welded together to enhance the overall structural strength.

[0008] Furthermore, the opening of the concave crossbar angle steel faces the running direction of the crane rail sweeper, and after installation, the bottom edge is 10mm away from the rail surface, ensuring effective cleaning of rail debris while avoiding equipment interference.

[0009] Furthermore, buffer pads are installed on the inner wall of the crossbar angle steel.

[0010] Furthermore, the bottom of the crossbar angle steel is provided with an elastic scraper, which is made of rubber or polyurethane.

[0011] Furthermore, guide ramps are added to both sides of the opening of the concave crossbar angle steel to guide the crescent-shaped stop into the groove in extreme cases, reducing the risk of collision.

[0012] The beneficial effects of this utility model are as follows: This invention avoids direct collision with the crescent-shaped stop, extending service life by 3 times; reduces equipment downtime and improves production efficiency; reduces maintenance costs by more than 60%; has a simple and reliable structure and is easy to install; ensures the safety of the crane's trolley and crane running track areas; and is suitable for various specifications of track systems.
