[0031] There are two groups of running wheels 203, each group of running wheels 203 is provided with two, and the two groups of running wheels 203 are symmetrically distributed;

[0032] There are two sets of driving bevel gears 207 and driven bevel gears 209, and the two sets of driving bevel gears 207 and driven bevel gears 209 are the same in size and shape, and the two sets of driving bevel gears 207 and driven bevel gears 209 are meshed with the linkage bevel gear 208;

[0033] There are three groups of limit blocks 211, each group of limit blocks 211 has two limit blocks, and the cross-sections of the three groups of limit blocks 211 are all annular;

[0034] Specifically, Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, when in use, the adjusting motor 212 is started to drive the adjusting rod 210 to rotate, and then the linkage bevel gear 208 is driven to rotate. On the one hand, the sliding block 206 is driven to move downward under the action of the active bevel gear 207 and the active shaft 205, and the sealing gasket 8 is driven to move downward synchronously under the action of the pressure plate 7, so that the sealing gasket 8 and the valve are fitted with each other.

[0038] Specifically, Figure 1 , Figure 5 As shown, when in use, by providing three fixed pipes 5, multiple valves can be pressure tested synchronously, thereby improving its flexibility.

[0039] Working principle: When the utility model is used, first, the assembled pressure test platform 1 is moved to the designated location through the walking wheel 203, and the valve to be pressure tested is placed on the top of the pressure test platform 1, and the adjusting motor 212 is started to drive the adjusting rod 210 to rotate, and the adjusting rod 210 drives the linkage bevel gear 208 to rotate synchronously while the adjusting rod 210 rotates. Since the linkage bevel gear 208 and the active bevel gear 207 are meshed with each other, the linkage bevel gear 208 drives the active bevel gear 207 to rotate synchronously while the active bevel gear 207 rotates. When the driving shaft 205 moves, it drives the driving shaft 205 to make synchronous rotational movement, thereby driving the sliding block 206 to slide inside the guide groove 9. The guide groove 9 can limit the moving sliding block 206 on the one hand to avoid its position deviation, and can also guide the moving sliding block 206 on the other hand, so that the sliding block 206 moves more stably. When the sliding block 206 moves downward, it drives the pressing plate 7 to make synchronous downward movement until one side of the sealing gasket 8 and one side of the valve are in contact with each other. The valve is automatically sealed through the above operation, thereby improving its working efficiency.

[0040] Then, in the process of starting the adjusting motor 212, the adjusting rod 210 is driven to rotate, thereby driving the linked bevel gear 208 to perform a synchronous rotational movement. Since the linked bevel gear 208 and the driven bevel gear 209 are meshed with each other, the linked bevel gear 208 rotates and drives the driven bevel gear 209 to perform a synchronous rotational movement. By setting a limiting block 211, the linked bevel gear 208 and the driven bevel gear 209 that move for a long time can be limited to avoid their positional deviation. While the driven bevel gear 209 rotates, it drives the driven shaft 201 to perform a synchronous rotational movement, thereby driving the moving block 202 to perform an upward movement. While the moving block 202 moves upward, it drives the moving plate 204 to perform a synchronous upward movement, thereby driving the walking wheel 203 to perform a synchronous upward movement until the walking wheel 203 is away from the ground, thereby improving the stability of the pressure test platform 1 during use, avoiding the shaking phenomenon during use, thereby improving the accuracy of the pressure test.
