[0002] A sealing test equipment is an instrument specifically used to detect the sealing performance of components or systems. The equipment usually includes a fixed seat and a pressure test mechanism.

[0003] During the test, the train brake cylinder is placed on the fixed seat of the test equipment, and it is ensured that it is stable without shaking. Then the test equipment is started, and a preset test pressure is applied to the brake cylinder through the pressure test mechanism. During the test, the detection element will monitor the sealing performance of the brake cylinder in real time, including parameters such as pressure change and leakage volume. If there is leakage in the brake cylinder, the detection element will issue an alarm in time or record relevant data to complete the detection of the train brake cylinder.

[0004] However, during the process of implementing the technical solution of the present invention in the embodiments of the present application, the inventors of the present application found that the above technology has at least the following technical problems:

Specific Embodiments

[0039] The following is a description of the preferred embodiments of the present utility model with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present utility model and are not used to limit the present utility model.

[0040] Among them, the same reference numerals in the accompanying drawings all refer to the same components. Embodiment

[0041] As Figure 1-5 shown, the present utility model provides a train brake cylinder sealing performance test equipment, including the main body 1 of the test equipment.

The fixed seat 4 is arranged on the top surface of the workbench 3, and the pressure test mechanism 2 is arranged on the top surface of the workbench 3. The pressure test mechanism 2 includes:

[0042] a cylinder block 5, having an accommodating space 501 and a cylinder bore 502. The cylinder block 5 is arranged on one side of the pressure test mechanism 2, and the cylinder bore 502 is arranged at the center of one side of the cylinder block 5;

[0043] The mounting plate 6 is welded to one side of the bottom surface inside the cylinder block 5.

[0044] The upper plates 7, and two groups of upper plates 7 are welded to one side of the mounting plate 6.

[0045] The rubber columns 8, which have damping springs 801, and two groups of rubber columns 8 are fixedly connected to the centers of the two groups of upper plates 7, and the damping springs 801 are attached to the outer surfaces of the rubber columns 8.

[0046] The lower plates 9, and two groups of lower plates 9 are arranged on the other side surfaces of the two groups of rubber columns 8.

[0047] Among them, the two groups of upper plates 7 and the two groups of lower plates 9 are arranged in parallel.

[0048] The buckle plate 10, which has a groove 101, and the buckle plate 10 is arranged on the bottom surfaces of the two groups of lower plates 9, and the groove 101 is arranged at the center of the buckle plate 10.

[0049] The rubber pad 11, and the rubber pad 11 is arranged inside the groove 101.

[0050] The movable rod 12, and the movable rod 12 is arranged inside the accommodation space 501.

[0051] Among them, the top of the movable rod 12 is buckled and fixed inside the groove 101, the top of the movable rod 12 is attached to the rubber pad 11, and the other side of the movable rod 12 passes through the cylinder hole 502.

[0052] Specifically, as Figure 1-5 shown, the mounting plate 6 is used to mount the upper plate 7, the upper plate 7 is used to mount the rubber columns 8 and the damping springs 801, the lower plate 9 is used to mount the rubber columns 8 and the damping springs 801, and at the same time the buckle plate 10 is mounted. The rubber columns 8 and the damping springs 801 are used to slow down the force generated when the movable rod 12 hits the buckle plate 10. When the movable rod 12 moves up and down inside the cylinder block 5, the bottom of the movable rod 12 will hit the groove 101 inside the buckle plate 10, thereby squeezing the buckle plate 10 towards the rubber columns 8 and the damping springs 801. After the rubber columns 8 and the damping springs 801 are subjected to force, they will undergo horizontal deformation, converting the larger force into a smaller force, and then returning to the static state to complete the shock absorption process. At the same time, the rubber pad 11 arranged inside the groove 101 can slow down the friction generated when the movable rod 12 hits the buckle plate 10 and reduce the loss of the movable rod 12.

[0053] The upper plates 7 and the lower plates 9 have the same size. The rubber columns 8 are arranged at the central parts of the upper plates 7 and the lower plates 9, and the rubber columns 8 are perpendicular to the upper plates 7 and the lower plates 9.

[0060] Specifically, as Figure 1-5 shown, the first connecting plate 14 is used to fixedly connect the fixing base 4 to the surface of the workbench 3. The mounting block 142 is used to snap-fix the first connecting plate 14 to the second connecting plate 15. The mounting groove 152 is used to mount the mounting block 142. The first jack 141 and the second jack 151 are used to mount the bolt 16. The bolt 16 is used to insert into the first jack 141 and the second jack 151 to threadedly fix the first connecting plate 14 to the second connecting plate 15, thereby fixing the fixing base 4 to the workbench 3.

[0061] The first connecting plate 14 and the second connecting plate 15 have the same dimensions, and the mounting block 142 and the mounting groove 152 have the same dimensions, both of which are rectangularly arranged.

[0062] The first jack 141 and the second jack 151 are internally threaded. The first jack 141 and the second jack 151 have the same aperture, and the shaft diameter of the bolt 16 is the same as the aperture of the first jack 141 and the second jack 151.

[0063] Instructions for use: After the device is started, the movable rod 12 in the pressure testing mechanism will move inside the cylinder block 5. The bottom of the movable rod 12 will hit the groove 101 inside the buckle plate 10, thereby squeezing the buckle plate 10 towards the rubber column 8 and the damping spring 801. After the rubber column 8 and the damping spring 801 are subjected to force, they will produce horizontal deformation, converting the larger force into a smaller force, and then returning to the static state to complete the shock absorption treatment. At the same time, the rubber pad 11 provided inside the groove 101 can slow down the friction generated when the movable rod 12 hits the buckle plate 10 and reduce the loss of the movable rod 12; when it is necessary to disassemble and replace the fixing seat 4, take out the bolt 16 from the first jack 141 and the second jack 151, and then remove the fixing seat 4 from the top surface of the workbench 3 to complete the portable disassembly of the fixing seat 4.
