Description

Technical Field

[0001] This utility model relates to the field of monorail braking technology in coal mines, and in particular to a tool for disassembling and assembling a monorail braking device for coal mines. Background Technology

[0002] Monorail locomotives are the main auxiliary transportation equipment in coal mines. The braking device of a monorail locomotive is a key safety component. This braking device mainly consists of springs and hydraulic cylinders. When the monorail locomotive starts and the control handle is opened, the brake cylinder will contract and tighten the spring, thus releasing the locomotive's brake and allowing the monorail locomotive to run. When the monorail locomotive malfunctions and stops, the lack of hydraulic pressure in the brake cylinder causes the spring to automatically reset, and the brake, under the action of the spring, holds the rail, bringing the monorail locomotive to a smooth stop.

[0003] During operation, the braking system of a monorail crane may frequently activate, or problems such as track quality or driver error may cause spring breakage or hydraulic cylinder leakage. Failure to replace these issues promptly will severely impact the braking performance and safety of the monorail. Furthermore, the high elasticity of the brake cylinder springs makes them difficult to control, and replacing broken springs or damaged cylinders can easily injure workers. Therefore, this invention proposes a tool for disassembling and assembling the braking system of a monorail crane used in coal mines to address the shortcomings of existing technologies. Utility Model Content

[0004] To address the aforementioned problems, the purpose of this utility model is to provide a tool for disassembling and assembling a braking device for a monorail crane in a coal mine. By disassembling the bracket to position the braking device, a pneumatic oil pump provides braking force to the cylinder, causing the push frame installed at the output end of the cylinder to compress the brake cylinder spring of the braking device. This exposes the position of the brake cylinder fixing nut located inside the brake cylinder spring, allowing for the disassembly or installation of the brake cylinder and brake cylinder spring.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A tool for disassembling and assembling a braking device for a monorail crane in a coal mine includes a storage frame, a pneumatic oil pump, a shut-off valve, a hydraulic cylinder, and a disassembly bracket. The storage frame houses the pneumatic oil pump, and the output end of the pneumatic oil pump is equipped with a flexible oil pipe. A shut-off valve is installed on the flexible oil pipe. The disassembly bracket is equipped with a hydraulic cylinder, one end of which is connected to the oil inlet of the hydraulic cylinder. The output end of the hydraulic cylinder is located inside the disassembly bracket and is equipped with a pusher. The internal width of the disassembly bracket is adapted to the diameter of the brake cylinder spring. The disassembly bracket is equipped with a positioning component, and the disassembly bracket can be detachably assembled with the storage rack through the positioning component.

[0006] A further improvement is that: one end of the disassembly bracket is symmetrically provided with sliding holes, a sliding rod is slidably provided inside the sliding holes, a support seat is slidably provided on the outside of the oil cylinder, and one end of the sliding rod is connected to one side wall of the support seat.

[0007] A further improvement is that the storage rack is equipped with casters at the four corners of its bottom, and the casters are equipped with brake pads.

[0008] A further improvement is that a positioning rod is detachably installed on one side inside the disassembly bracket. The diameter of the positioning rod is adapted to the diameter of the mounting hole at the tail end of the brake cylinder spring, and the upper end of the positioning rod extends out of the disassembly bracket.

[0009] A further improvement is that the positioning component includes side beams and positioning holes. Side beams are provided on both sides of the disassembly bracket, and positioning holes are symmetrically provided on the side beams. The top of the storage rack is provided with positioning pins that are adapted to the positioning holes.

[0010] Further improvements include: a handle is provided between the two positioning holes on the side beam, and a storage groove adapted to the size of the shut-off valve is provided on one side wall of the storage rack.

[0011] The beneficial effects of this utility model are as follows: This utility model, by setting up a disassembly and assembly tool consisting of a storage rack, a pneumatic oil pump, a shut-off valve, an oil cylinder, and a disassembly bracket, can position the braking device by disassembling the bracket. Then, the pneumatic oil pump provides braking force to the oil cylinder, causing the push frame installed at the output end of the oil cylinder to compress the brake cylinder spring of the braking device. This exposes the position of the brake cylinder fixing nut located inside the brake cylinder spring for disassembly or installation. Then, the brake cylinder and brake cylinder spring can be disassembled and assembled. The shut-off valve can lock the piston rod of the oil cylinder to prevent pressure leakage, ensuring the safe disassembly or installation of the brake cylinder and brake cylinder spring. This utility model enables the disassembly bracket to be stored as a whole on a storage rack by setting a positioning component. After storage, the tools are integrated into a small size, making them easy to move and store. Attached Figure Description

[0014] To deepen the understanding of this utility model, the following detailed description will be provided in conjunction with embodiments. These embodiments are only used to explain this utility model and do not constitute a limitation on the scope of protection of this utility model.

[0015] according to Figure 1-2 As shown in the figure, this embodiment proposes a disassembly and assembly tool for a monorail crane braking device in a coal mine, including a storage frame 1, a pneumatic oil pump 2, a shut-off valve 3, a cylinder 4, and a disassembly bracket 5. The pneumatic oil pump 2 is installed inside the storage frame 1, and a flexible oil pipe 6 is provided at the output end of the pneumatic oil pump 2. The shut-off valve 3 is provided on the flexible oil pipe 6. The cylinder 4 is installed on the disassembly bracket 5. One end of the flexible oil pipe 6 is connected to the oil inlet of the cylinder 4. The output end of the cylinder 4 is located inside the disassembly bracket 5 and a pusher 7 is installed thereon. The internal width of the disassembly bracket 5 is adapted to the diameter of the brake cylinder spring 8. The disassembly bracket 5 is provided with a positioning component, and the disassembly bracket 5 can be detachably assembled and disassembled with the storage frame 1 through the positioning component.

[0016] This utility model discloses a tool for disassembling and assembling the braking device of a monorail crane used in coal mines. When disassembling or assembling the braking device, the device is placed inside the disassembly bracket 5. After starting the pneumatic oil pump 2, it supplies hydraulic oil to the cylinder 4. The piston rod (output end) of the cylinder 4 extends, driving the push frame 7 to move and compress the brake cylinder spring 8. When the brake cylinder spring 8 is compressed, the brake cylinder fixing nut is exposed, facilitating the disassembly and assembly of the braking device. To prevent pressure leakage from the cylinder 4, after the piston rod (output end) extends to a suitable position, the piston rod of the cylinder 4 is locked by closing the shut-off valve 3.

[0017] The disassembly bracket 5 has symmetrical sliding holes at one end, and a sliding rod 9 is slidably mounted inside the sliding holes. A support seat 10 is slidably mounted on the outside of the hydraulic cylinder 4, and one end of the sliding rod 9 is connected to one side wall of the support seat 10. By providing a sliding support seat 10, the hydraulic cylinder 4 can be supported from different positions, ensuring the balance between the hydraulic cylinder 4 and the disassembly bracket 5.

[0018] The storage rack 1 is equipped with four casters 11 at the bottom corners, and each caster 11 has a brake pad. By providing the casters 11, the storage rack 1 of this invention is easy to move, improving its flexibility of use.

[0019] A positioning rod 12 is detachably installed on one side inside the disassembly bracket 5. The diameter of the positioning rod 12 is adapted to the diameter of the mounting hole at the tail end of the brake cylinder spring 8, and the upper end of the positioning rod 12 extends out of the disassembly bracket 5. By setting the positioning rod 12, the position of the brake cylinder spring 8 inside the disassembly bracket 5 can be limited, which facilitates the stable compression of the brake cylinder spring 8 by the push frame 7.

[0020] The positioning assembly includes side beams 13 and positioning holes 14. Side beams 13 are provided on both sides of the disassembly bracket 5, and positioning holes 14 are symmetrically provided on the side beams 13. Positioning pins 15, adapted to the positioning holes 14, are provided on the top of the storage rack 1. A further improvement is that a handle 16 is provided between the two positioning holes 14 on the side beams 13, and a storage groove 17, adapted to the size of the shut-off valve 3, is provided on one side wall of the storage rack 1. After use, the disassembly bracket 5 is lifted by the handle 16, and the positioning holes 14 on the side beams 13 of the disassembly bracket 5 are aligned with the positioning pins 15 on the top of the storage rack 1. The disassembly bracket 5 is then placed on the storage rack 1, and the shut-off valve 3 can be stored in the storage groove 17, making the entire tool a single unit, facilitating overall movement via the casters 11.

[0021] This utility model, through the provision of a disassembly and assembly tool consisting of a storage rack 1, a pneumatic oil pump 2, a shut-off valve 3, an oil cylinder 4, and a disassembly bracket 5, allows for the positioning of the braking device via the disassembly bracket 5. The pneumatic oil pump 2 then provides braking force to the oil cylinder 4, causing the pusher bracket 7 mounted on the output end of the oil cylinder 4 to compress the brake cylinder spring 8 of the braking device. This exposes the position for disassembling or installing the brake cylinder fixing nut located inside the brake cylinder spring 8. The brake cylinder and brake cylinder spring 8 can then be disassembled and assembled. The shut-off valve 3 locks the piston rod of the oil cylinder 4 to prevent pressure leakage, ensuring the safe disassembly or installation of the brake cylinder and brake cylinder spring 8. Furthermore, the positioning component allows the disassembly bracket 5 to be stored as a whole on the storage rack 1. After storage, the tool is integrated and compact, facilitating movement and storage.
