[0028] Among them, the number of the clamping components 10 is multiple. The multiple clamping components 10 are distributed in an equidistant linear array inside the main frame 1. The number of the jacking components 11 is multiple. Inside the main frame 1, there is a pipeline 15 to be pressure-tested movably connected.

[0029] The multiple number of the clamping components 10 can improve the clamping effect on the pipeline 15 to be pressure-tested. The jacking component 11 can jack out the pipeline 15 to be pressure-tested.

The outside of the pushing cylinder 41 and the outside of the sealing head body 5 are fixedly connected.

[0031] Starting the pushing cylinder 41 can make the sealing head body 5 move left and right, and then the two ends of the pipeline 15 to be pressure-tested can be sealed.

[0032] Among them, the clamping component 10 includes two positioning plates 101 fixedly connected to the inside of the main frame 1. On the outside of the positioning plates 101, there are fixed limit rods 102. On the outside of the limit rods 102, there are two slidable clamping plates 103. At the bottom of the clamping plates 103, there are fixed moving racks 104. Inside the main frame 1, there is a connecting gear 105 rotatably connected.

[0033] Activating the clamping cylinder 106 can cause one of the clamping plates 103 to move, which in turn can cause the moving rack 104 to move, driving the connecting gear 105 to rotate. Through the moving rack 104, the other clamping plate 103 will be driven to move, and then the pipeline 15 to be pressure-tested can be clamped.

[0034] Among them, the jacking assembly 11 includes a jacking cylinder 111 fixedly connected to the outside of the main frame 1.

[0038] Working principle:

[0039] After moving the pipeline 15 to be pressure-tested to the inside of the main frame 1, activating the first cylinder 141 and the second cylinder 143 can cause the arc-shaped plate 144 to move, and the pipeline 15 to be pressure-tested can be pre-fixed through the arc-shaped plate 144;

[0040] Activating the clamping cylinder 106 can cause one of the clamping plates 103 to move, which in turn can cause the moving rack 104 to move, driving the connecting gear 105 to rotate. Through the moving rack 104, the other clamping plate 103 will be driven to move, and then the pipeline 15 to be pressure-tested can be clamped;

[0041] After clamping, activating the pushing cylinder 41 can cause the sealing head body 5 to move left and right, and then the two ends of the pipeline 15 to be pressure-tested can be sealed. Subsequently, the hydraulic pump station 3 is started, and water will be introduced into the inside of the sealing head body 5 through the water injection pipe 8 and then into the inside of the pipeline 15 to be pressure-tested. At the same time, the exhaust valve 6 can discharge the gas inside the pipeline 15 to be pressure-tested. After the discharge is completed, the high-pressure pump 2 is started, and then the pipeline 15 to be pressure-tested can be pressure-tested.
