Description

Technical Field

[0001] This utility model belongs to the technical field of automotive repair equipment, and relates to an auxiliary device for disassembling brake chambers. Background Technology

[0002] The brake chamber is a critical component of the automotive braking system, and its proper functioning is essential for vehicle safety. After a certain period of vehicle use, the brake chamber needs to be disassembled for repair or parts replacement. However, the return spring inside the brake chamber is in a compressed state, storing a significant amount of elastic potential energy. Currently, in actual repair work, operators often rely on experience to manually press down on the chamber housing for disassembly. During disassembly, without a suitable restraint device to control the spring force, the chamber housing can easily spring open suddenly under the spring force, damaging the chamber components and potentially causing serious injury to the operator. Utility Model Content

[0003] This utility model provides a brake chamber disassembly device to solve the safety hazards existing in the current brake chamber disassembly process.

[0004] To solve the above problems, the technical solution adopted by this utility model is as follows: A frame comprising an air chamber positioning plate, a manual reversing valve, and a pneumatic triplet is included. The air chamber positioning plate has a through hole and multiple positioning holes. The brake air chamber is positioned and fixed through the through hole and the multiple positioning holes. The push rod of the brake air chamber extends from top to bottom into the through hole, and two mounting bolts of the brake air chamber are respectively screwed into two of the positioning holes, thus fixing the brake air chamber onto the air chamber positioning plate. Multiple columns are provided at the bottom of the air chamber positioning plate, and a cylinder mounting plate is provided between the lower parts of the multiple columns. A cylinder is mounted on a cylinder mounting plate. The piston rod of the cylinder extends to the through hole and is equipped with a push rod connecting block. The push rod connecting block is used to connect with the brake chamber push rod. The cylinder is connected to the manual reversing valve. The manual reversing valve is connected to the pneumatic triplet. The pneumatic triplet is connected to a compressed air supply source. The airflow provided by the compressed air supply source first enters the pneumatic triplet, is filtered (to remove moisture and impurities), and then flows to the manual reversing valve after pressure regulation. The manual reversing valve changes the airflow direction by manual operation, thereby controlling the extension and retraction of the piston rod of the cylinder.

[0005] A more specific technical solution than the above-mentioned technical solution is that the bottom of the air chamber positioning plate is provided with two columns, and the two columns are respectively connected to both ends of the cylinder mounting plate.

[0006] Furthermore, the frame is constructed from aluminum profiles, providing sufficient strength and stability.

[0007] Furthermore, the bottom of the frame is equipped with multiple casters.

[0008] Furthermore, the bottom of the frame is equipped with four casters.

[0009] Due to the adoption of the above technical solution, this utility model has the following beneficial effects compared with the prior art: The utility model has a reasonable structural design and simple operation process. Operators can use it proficiently after simple training, which improves the efficiency of brake chamber disassembly and reduces maintenance time and cost; by pulling the brake chamber push rod with a cylinder, the elastic force of the spring in the brake chamber is effectively controlled, preventing the brake chamber shell from popping open during disassembly, greatly reducing the risk of injury to operators, ensuring personal safety, and also reducing the possibility of damage to equipment parts; by arranging multiple positioning holes on the air chamber positioning plate, it can be used for the disassembly of brake chambers of various specifications and models, and can meet the disassembly needs of brake chambers of various vehicle models.

[0013] The present invention will be further described in detail below with reference to the accompanying drawings and examples: like Figure 1 and Figure 2The brake chamber disassembly device shown includes a frame 2 with a chamber positioning plate 1, a manual reversing valve 7, and a pneumatic triplet 8. The frame 2 is constructed of aluminum profiles assembled with bolts. Four casters 9 are mounted on the bottom of the frame 2 via bolt assemblies. The chamber positioning plate 1 has one through hole 10 and four sets of positioning holes 11. The distance between each set of positioning holes 11 is the same as the distance between two mounting bolts on existing brake chambers 12. The push rod of the brake chamber 12 extends from top to bottom into the through hole 10. Two mounting bolts of the brake chamber 12 are screwed into one set of positioning holes 11, thus fixing the brake chamber 12 onto the chamber positioning plate 1. Two columns 3 are fixed to the bottom of the chamber positioning plate 1 via bolt assemblies. The two columns 3 are connected to both ends of a cylinder mounting plate 4 via bolt assemblies. A cylinder 5 is mounted on the cylinder mounting plate 4. The cylinder body is fixedly mounted on the cylinder mounting plate 4 by bolt assembly. The piston rod of the cylinder 5 can extend to the through hole 10 in a straight line in the vertical direction. The end of the piston rod of the cylinder 5 is provided with a push rod connecting block 6. The push rod connecting block 6 is used to connect with the push rod of the brake chamber 12. One end of the push rod connecting block 6 is connected to the piston rod of the cylinder 5 by bolt assembly, and the other end of the push rod connecting block 6 is connected to the push rod of the brake chamber 12 by bolt assembly. The cylinder 5 is connected to the manual reversing valve 7. The manual reversing valve 7 is connected to the pneumatic triplet 8. The pneumatic triplet 8 is connected to the compressed air supply source. In this example, the compressed air supply source is an air compressor. The airflow provided by the air compressor first enters the pneumatic triplet 8. After being filtered and pressure regulated, the airflow flows to the manual reversing valve 7. The manual reversing valve 7 changes the direction of the air path by manual operation, thereby controlling the extension and retraction of the piston rod of the cylinder 5.

[0014] In use, place and fix the brake chamber 12 on the chamber positioning plate 1, rotate the manual reversing valve 7 to extend the piston rod of the cylinder 5 towards the push rod of the brake chamber 12, and connect the push rod connecting block 6 to the push rod of the brake chamber 12. Then rotate the manual reversing valve 7, the piston rod of the cylinder 5 retracts and applies a pulling force, pulling the push rod of the brake chamber 12 out, compressing and maintaining the spring inside the brake chamber 12, thereby overcoming the spring force. At this time, the housing of the brake chamber 12 can be disassembled. Since the spring force is counteracted by the cylinder 5, the housing of the brake chamber 12 will not pop open, and the operator can safely and smoothly carry out subsequent disassembly and maintenance work.
