[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] Reference Figure 1-Figure 3 A clamping device for pipeline pressure testing includes a workbench 1 with four legs fixed at the bottom, a support plate 2 fixedly connected to the top of the workbench 1, a pair of movable seats 3 are arranged above the workbench 1, disassembly plates 4 are relatively fixed on the movable seats 3, and arc-shaped pressure plates 5 are fixedly installed on opposite sides of the two disassembly plates 4; it should be noted that the arc-shaped pressure plate 5 is provided with an inner cavity, and a pressure sensor for monitoring pressure is installed in the inner cavity. After the arc-shaped pressure plate 5 is squeezed, the pressure is transmitted to the pressure sensor, thereby detecting the pressure.

[0023] The workbench 1 is provided with a moving structure for driving the moving seat 3 to move.

[0024] The movable structure includes a pair of slides 6 opened on the workbench 1, a pair of mounting ears 7 are fixedly connected to the bottom of the workbench 1, the two mounting ears 7 are rotatably connected to the same bidirectional screw 8 on the opposite side walls, a pair of sleeve blocks 9 are threadedly connected to the bidirectional screw 8, an L-shaped rod 10 is fixedly connected to the sleeve block 9, and the L-shaped rod 10 is slidably connected to the slide 6, and a motor 11 for driving the bidirectional screw 8 to rotate is fixed on the mounting ears 7; the purpose of the sliding connection between the L-shaped rod 10 and the slide 6 is to ensure that the sleeve block 9 can stably move along the axial direction of the bidirectional screw 8.

[0025] The L-shaped rod 10 is provided with a driving member for driving the moving seat 3 to move vertically.

[0026] The driving member includes a rotating rod 12 rotatably connected to the top of one of the L-shaped rods 10, a limiting rod 13 fixedly connected to the top of the other L-shaped rod 10, the rotating rod 12 is threadedly connected to the moving seat 3, and the limiting rod 13 is vertically slidably connected to the moving seat 3. The rotating rod 12 is provided with threads to facilitate the threaded connection between it and the moving seat 3.

[0027] A turning handle 14 is fixedly connected to the top of the rotating rod 12 for the convenience of workers to rotate the rotating rod 12 .

[0028] The two disassembly and assembly plates 4 are both fixedly connected with an insertion rod 15 on the back side. The insertion rod 15 slides transversely and penetrates the movable seat 3. The insertion rod 15 is threadedly connected with an anti-slip ring 16.

[0029] The limiting rod 13 and the rotating rod 12 are symmetrically arranged, and the limiting rod 13 and the rotating rod 12 are respectively arranged above two different sliding openings 6. This ensures that the force of the moving seat 3 is balanced when moving, and prevents the rotation of the rotating rod 12 from causing the moving seat 3 to deviate.

[0030] The functional principle of the utility model can be explained through the following operation modes:

[0031] When using the device, first, place the pipe to be tested on the support plate 2, and the staff rotates the handle 14 according to the actual size of the pipe and the diameter of the pipe opening, and the handle 14 drives the rotating rod 12 to rotate, and the rotating rod 12 drives the moving seat 3 to move vertically, thereby realizing the vertical movement of the arc-shaped pressing plate 5;

[0032] After the arc pressure plate 5 moves vertically to a suitable position, the motor 11 is started, and the motor 11 drives the bidirectional screw 8 to rotate, and the bidirectional screw 8 drives the two sleeve blocks 9 to move relative to each other, and the two sleeve blocks 9 drive the L-shaped rod 10 to move relative to each other. The movement of the L-shaped rod 10 enables the two arc pressure plates 5 to move relative to each other until they fit with the outer wall of the pipeline. After the arc pressure plate 5 fits with the outer wall of the pipeline, it continues to move, and the pressure sensor in the arc pressure plate 5 thereby realizes pressure testing.

Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
