Description

Technical Field

[0001] This utility model relates to the field of pneumatic braking technology, and in particular to a pneumatic braking structure for an impact platform. Background Technology

[0002] A pneumatic brake structure is a support device for braking a pneumatic impact collision platform. Pneumatic impact collision platforms often use hydraulic braking mechanisms. High-pressure hydraulic oil is injected into pistons on both sides of the platform through a booster cylinder, which pushes the pistons to clamp the column and achieve the braking effect. With the continuous development of technology, people have increasingly higher requirements for the manufacturing process of pneumatic brake structures.

[0003] Existing braking structures have certain drawbacks. Hydraulic brakes are relatively complex, requiring the assembly of parts such as pistons, seals, guide seats, and platforms, making installation complicated and difficult. Hydraulic brakes operate at high pressures, and if the seals are not installed correctly or age, hydraulic oil leakage can easily occur, reducing braking force and polluting the workshop environment. Pneumatic impact test benches primarily use compressed gas as their power source. Using a booster cylinder for the brake increases the use of hydraulic oil, increasing the complexity of maintenance and requiring consideration of hydraulic oil deterioration and replacement. Therefore, we propose a pneumatic braking structure for the impact test bench. Utility Model Content

[0004] Technical problem solved: In view of the shortcomings of the prior art, this utility model provides a pneumatic brake structure for an impact platform. There is a cavity between the brake cylinder and the brake rubber. Air is supplied into the cavity through the air passage interface on the brake cylinder, which compresses the brake rubber, causing it to expand and deform and clamp the column to achieve the braking action. When the brake is released, the compressed gas is released from the air passage interface, and the brake rubber retracts and loses its clamping force. The pneumatic brake structure can move up and down along the column, which can effectively solve the problems in the background art.

[0005] Technical Solution: To achieve the above objectives, the technical solution adopted by this utility model is as follows: a pneumatic brake structure for an impact platform, comprising a column and a brake cylinder, wherein the column is located in the middle of the brake cylinder, an upper brake mounting plate is installed on the top of the brake cylinder at a position on the outer wall of the column, a lower brake mounting plate is installed on the bottom of the brake cylinder at a position on the outer wall of the column, a brake rubber is provided inside the brake cylinder in close contact with the outer wall of the column, an air passage interface is provided in the middle of the outer wall of the brake cylinder, and a cavity is provided between the inside of the brake cylinder and the brake rubber.

[0006] Preferably, there is a cavity between the brake cylinder and the brake rubber, and the cavity is supplied with air through the air passage interface on the brake cylinder, and the brake rubber is compressed and controlled by the gas.

[0007] Preferably, during braking, the air inlet receives air and compresses the brake rubber, which then expands and deforms to grip the column, thus achieving the braking action.

[0008] Preferably, when the brake is released, compressed gas is released at the air inlet, and the brake rubber retracts and loses its grip on the column, thus releasing the brake.

[0009] Preferably, the gas line interface is connected to a gas compressor, and a gas line pipe, a gas line connector and a flange are connected between the gas line interface and the gas compressor. A sealing ring is positioned on the inner side of both the gas line connector and the flange. The gas line connector is located inside the gas line interface, and the flange is located outside the gas line interface.

[0010] Preferably, the gas compressor controls the input and release of compressed air at the gas line interface through a gas line pipe, and is sealed by a gas line connector, flange and sealing ring.

[0011] Beneficial Effects: Compared with the prior art, this utility model provides a pneumatic brake structure for an impact platform, which has the following beneficial effects: This pneumatic brake structure for an impact platform reduces the involvement of hydraulic oil, using only compressed air to provide power and braking force, thus optimizing the cleanliness of the equipment; the original hydraulic brake required the piston to be installed in the guide seat, which was cumbersome and difficult, while the pneumatic brake greatly optimizes the installation process; the pneumatic brake, as a separate component, can be built into the sides of the platform or placed on top of the platform, making the connection method more flexible and versatile. The brake cylinder and the brake rubber have a cavity inside, and air is supplied into the cavity through the air passage interface on the brake cylinder, squeezing the brake rubber, causing the brake rubber to expand and deform and clamp the column, thus achieving the braking action. When the brake is released, the compressed gas is released from the air passage interface, the brake rubber retracts and loses its clamping force, and the pneumatic brake structure can move up and down along the column. The entire pneumatic brake structure is simple in structure, easy to operate, and has a better effect than the traditional method. Attached Figure Description

[0018] like Figure 1 , 2 As shown, a pneumatic brake structure for an impact platform includes a column 1 and a brake cylinder 2. The column 1 is located in the middle of the brake cylinder 2. An upper brake mounting plate 5 is installed on the top of the brake cylinder 2 at the position of the outer wall of the column 1, and a lower brake mounting plate 6 is installed on the bottom of the brake cylinder 2 at the position of the outer wall of the column 1. A brake rubber 4 is provided inside the brake cylinder 2 in close contact with the outer wall of the column 1. An air passage interface 3 is provided in the middle of the outer wall of the brake cylinder 2. A cavity 7 is provided between the brake cylinder 2 and the brake rubber 4. Air is supplied into the cavity through the air passage interface on the brake cylinder, which compresses the brake rubber, causing it to expand and deform, and then grip the column to achieve the braking action. When the brake is released, the compressed gas is released from the air passage interface, and the brake rubber retracts and loses its gripping force. The pneumatic brake structure can move up and down along the column.

[0019] Furthermore, there is a cavity 7 between the brake cylinder 2 and the brake rubber 4, and air is supplied into the cavity 7 through the air passage interface 3 on the brake cylinder 2, and the air compresses and controls the brake rubber 4.

[0020] Furthermore, during braking, the air inlet 3 receives air and compresses the brake rubber 4. After the brake rubber 4 expands and deforms, it grips the column 1 to achieve the braking action.

[0021] Furthermore, when the brake is released, compressed gas is released at the air inlet 3, and the brake rubber 4 retracts and loses its grip on the column 1, thus releasing the brake.

[0022] Furthermore, the gas interface 3 is connected to a gas compressor 8, and a gas pipe 9, a gas connector 10, and a flange 11 are connected between the gas interface 3 and the gas compressor 8. A sealing ring 12 is positioned on the inner side of both the gas connector 10 and the flange 11. The gas connector 10 is located inside the gas interface 3, and the flange 11 is located outside the gas interface 3.

[0023] Furthermore, the gas compressor 8 controls the input and release of compressed air at the gas interface 3 through the gas pipe 9, and is sealed through the gas connector 10, flange 11 and sealing ring 12.

[0024] Working principle: This utility model includes a column 1, a brake cylinder 2, an air passage interface 3, a brake rubber 4, an upper brake mounting plate 5, a lower brake mounting plate 6, a cavity 7, a gas compressor 8, an air passage pipe 9, an air passage connector 10, a flange 11, and a sealing ring 12. To reduce the use of air, hydraulic, and electrical components on the pneumatic impact collision platform, the original hydraulic brake was changed to a pneumatic brake, optimizing the complexity of brake installation and improving the operability of maintenance. The brake cylinder and the brake rubber share a cavity. Air is supplied to the cavity through the air passage interface on the brake cylinder, compressing the brake rubber and causing it to expand. After deformation, it grips the column to achieve the braking action. When the brake is released, compressed gas is released from the air circuit interface, and the brake rubber retracts and loses its gripping force. The pneumatic brake structure can move up and down along the column, reducing the involvement of the original hydraulic oil and using only compressed air to provide power and braking force, thus optimizing the cleanliness of the equipment. The original hydraulic brake required the piston to be installed in the guide seat, which was a complicated and difficult installation process. The installation process has been greatly optimized after the adjustment to the pneumatic brake. As a separate component, the pneumatic brake can be built into the sides of the table or placed on top of the table, making the connection method more flexible and versatile.
