Description

Technical Field

[0001] This utility model belongs to the field of brakes, specifically relating to a bidirectional braking shoe for running wheels. Background Technology

[0002] The bidirectional braking shoe for traveling wheels is a common device in port equipment, mechanical engineering, mining machinery, and industrial transmission systems. It is mainly used for braking control of traveling wheels and slewing wheels, and plays an important role, especially in traveling equipment or heavy machinery.

[0003] Existing travel wheel brake shoes suffer from insufficient braking performance and slow response, requiring manual on-site intervention. This is especially problematic during severe weather, which can easily cause displacement during equipment movement and rotation, leading to equipment damage and affecting stability. Utility Model Content

[0004] This utility model addresses the shortcomings of existing equipment by providing a bidirectional braking shoe for the running wheel. The specific technical solution is as follows:

[0005] A bidirectional braking shoe for running wheels includes a brake box and a shoe. Two brake boxes are symmetrically arranged, and a connecting rod is fixed between the two brake boxes. A cylinder for driving is installed inside the brake box. A first rotating shaft connected to the brake box is installed at the upper end of the cylinder, and a second rotating shaft is installed at the lower end of the cylinder. A wheel frame is fixed at the lower end of the brake box. A driving part is integrally formed at the end of the shoe and is rotatably connected to the second rotating shaft. A rotating part is integrally formed at the connection between the shoe and the driving part and is rotatably connected to the wheel frame. A brake pad for braking the running wheels is fixed on the surface of the shoe. A scraper for scraping impurities from the rail surface is integrally formed on the lower surface of the shoe away from the driving part.

[0006] A magnetic positioning element is provided between the iron shoe and the brake pad.

[0007] The magnetic positioning component includes a limit rod integrally formed on the surface of the brake pad, a limit slot opened on the surface of the shoe, a magnet block glued and fixed in the limit slot, and the limit rod inserted into the limit slot and fixed to the magnet block by magnetic force.

[0008] There are three integrally formed limit rods on the surface of the brake pad and three limit slots on the surface of the brake shoe, with each limit rod and limit slot corresponding to the other.

[0009] The surface of the brake pad that contacts the running wheel is curved, and grooves are formed on the curved surface of the brake pad.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] 1. Two symmetrically arranged brake boxes, connected by a connecting rod, facilitate bidirectional braking of the running wheels, improving braking performance during dual braking. A cylinder is rotatably mounted within the brake box via a first rotating shaft, with its lower end connected to the drive unit via a second rotating shaft. A wheel frame fixed at the lower end of the brake box is rotatably connected to the rotating unit. When the cylinder is connected to an external air source, the cylinder's extension / retraction end rotates the drive unit around the rotating unit, causing the brake shoe to move closer to or away from the running wheel, ensuring the brake pads are in close contact with the wheel for braking. The cylinder's extension / retraction can adjust the brake pad contact force and braking time as needed, improving system response speed and accuracy. An integrally formed scraper on the lower surface of the brake shoe away from the drive unit allows it to contact the guide rail when the cylinder retracts and the brake pads move away from the running wheel. This scraper removes impurities from the guide rail surface, preventing wheel vibration caused by impurity buildup.

[0012] 2. The magnetic positioning component between the brake shoe and the brake pad facilitates the fixing of the brake pad to the brake shoe, enabling quick disassembly and replacement of the brake pad. The magnetic positioning component includes a limiting rod integrally formed on the surface of the brake pad and a limiting slot opened on the surface of the brake shoe. When the limiting rod is inserted into the limiting slot, it is fixed by a magnet that is bonded and fixed inside the limiting slot, thus fixing the brake pad to the brake shoe by magnetic force.

[0018] The technical solution of this utility model will now be described with reference to the accompanying drawings and embodiments.

[0019] Please see Figure 1-4 This embodiment provides the following technical solution: a bidirectional braking shoe for running wheels, including a brake box 2 and a shoe 7. Two brake boxes 2 are symmetrically arranged, and a connecting rod 1 is fixed between the two brake boxes 2. A cylinder 3 for driving is provided inside the brake box 2. A first rotating shaft 4 rotatably connected to the brake box 2 is installed at the upper end of the cylinder 3, and a second rotating shaft 5 is installed at the lower end of the cylinder 3. A wheel frame 6 is fixed at the lower end of the brake box 2. A driving part 9 is integrally formed at the end of the shoe 7, and the driving part 9 is rotatably connected to the second rotating shaft 5. A rotating part 8 is integrally formed at the connection between the shoe 7 and the driving part 9, and the rotating part 8 is rotatably connected to the wheel frame 6. A brake pad 10 for braking the running wheels is fixed on the surface of the shoe 7. A scraper 15 for scraping impurities on the rail surface is integrally formed on the lower surface of the shoe 7 away from the driving part 9.

[0020] In this embodiment, two symmetrically arranged brake boxes 2 are connected by a connecting rod 1, which facilitates the bidirectional braking shoe to achieve dual-side braking of the running wheels, improving the braking performance of the running wheels when performing dual braking. A cylinder 3 is rotatably mounted inside the brake box 2 via a first rotating shaft 4. Simultaneously, the lower end of the cylinder 3 is rotatably connected to the drive unit 9 via a second rotating shaft 5. The wheel frame 6 fixed at the lower end of the brake box 2 is rotatably connected to the rotating unit 8, thus facilitating the extension and retraction of the cylinder 3 when it is connected to an external air source. The drive unit 9 rotates around the rotating unit 8, causing the iron shoe 7 to move closer to or away from the running wheel along with the brake pad 10. The brake pad 10 is in close contact with the running wheel to achieve the purpose of braking. The scraper 15 integrally formed on the lower surface of the iron shoe 7 away from the drive unit 9 causes the scraper 15 integrally formed on the lower surface of the iron shoe 7 to contact the guide rail when the cylinder 3 retracts and the brake pad 10 moves away from the running wheel. This makes it easier for the scraper 15 to scrape away impurities on the surface of the guide rail, avoiding the problem of the running wheel bumping on the track caused by the accumulation of impurities on the guide rail surface.

[0021] In this embodiment, a magnetic positioning component is provided between the iron shoe 7 and the brake pad 10. The magnetic positioning component includes a limiting rod 11 integrally formed on the surface of the brake pad 10, a limiting slot 12 is opened on the surface of the iron shoe 7, a magnet block 13 is bonded and fixed in the limiting slot 12, and the limiting rod 11 is inserted into the limiting slot 12 and fixed with the magnet block 13 by magnetic force.

[0022] In this embodiment, a magnetic positioning component is provided between the shoe 7 and the brake pad 10, which facilitates the fixing of the brake pad 10 to the shoe 7 via the magnetic positioning component, and facilitates the quick disassembly and replacement of the brake pad 10. The magnetic positioning component includes a limiting rod 11 integrally formed on the surface of the brake pad 10 and a limiting slot 12 opened on the surface of the shoe 7. When the limiting rod 11 is inserted into the limiting slot 12, the limiting rod 11 is fixed by a magnet block 13 bonded and fixed in the limiting slot 12, so that the brake pad 10 is fixed to the shoe 7 by magnetic force.

[0023] In this embodiment, three limiting rods 11 integrally formed on the surface of the brake pad 10 are provided, and three limiting slots 12 are provided on the surface of the iron shoe 7. The limiting rods 11 and the limiting slots 12 correspond one-to-one, which increases the stability of the brake pad 10 installed on the surface of the iron shoe 7.

[0024] In this embodiment, the surface of the brake pad 10 that contacts the running wheel is curved, and a groove 14 is provided on the curved surface of the brake pad 10 to facilitate the brake pad 10 to fit tightly against the running wheel. At the same time, the groove 14 provided on the curved surface of the brake pad 10 increases the surface roughness of the brake pad 10, which facilitates braking of the running wheel.
