Description

Technical Field

[0001] The utility model belongs to the technical field of pipe water pressure testing, and in particular relates to a sealing mould positioning device for pipe water pressure testing equipment. Background Art

[0002] The traditional method for testing pipes using water pressure is to seal the ends of the pipes, fill the pipes with pressurized water to the required pressure, and maintain the pressure for a specified time. During this period, the pipes are inspected to see if they deform under pressure or if there are any leaks to determine if they are qualified. This method can detect defects in the pipes that are not easily visible to the naked eye, such as microcracks and small pores. The existing water pressure testing equipment adopts two sets of sealing molds for pipe head connection sealing located on the same straight line to connect with the end of the pipe. After the end face tightening cylinder piston rod is extended, the end of the pipe is pressed against the sealing ring of one of the sealing molds, and the other end of the pipe is pressed against the sealing ring of another sealing mold with a fixed position, thereby achieving sealing of the pipe end; this structure is only suitable for water pressure sealing tests of fixed-length straight pipes, because the size of fixed-length pipes is fixed, so the bracket supporting the sealing mold is a welded fixed structure. However, if a water pressure test is performed on random-size pipes, due to the large length range of random-size pipes, the bracket of the sealing mold needs to be frequently de-welded, which is time-consuming and labor-intensive, very inconvenient, and repeated de-welding is labor-intensive. Therefore, it is necessary to propose improvements to the above problems. Utility Model Content

[0003] The technical problem solved by the present invention is to provide a sealing mold adjusting device for pipe water pressure testing equipment, which realizes the adjustment of the position of the sealing mold by arranging a seat plate on the frame of the water pressure testing equipment, which is adjustably fixed to the frame by a locking connection component, and supports and fixes the sealing mold by a support seat arranged on the seat plate, thereby solving the disadvantage that fixed-length water pressure testing equipment cannot perform sealing tests on random-length pipe fittings, and meets the sealing and fixing requirements of water pressure tests on random-length pipe fittings. The utility model has a simple structure, reasonable design, convenient and quick adjustment of the sealing mold position, time-saving and labor-saving disassembly and assembly, low cost, large sealing and fixing range of random-length pipe fittings, and high use value.

[0004] The technical solution adopted by the utility model is as follows: a sealing mold positioning device for pipe water pressure testing equipment includes a seat plate, a support seat for supporting the sealing mold is fixed on the upper surface of the seat plate, the bottom guide of the seat plate is adapted to the frame of the water pressure testing equipment, and the position of the sealing mold is adjusted by moving the seat plate along the length direction of the frame. The seat plate adjusted into place is detachably fixed to the frame through a locking connection assembly.

[0005] Among them, two guide plates are fixed on both sides of the bottom surface of the seat plate, which are arranged in parallel and form a U-shaped groove with the seat plate, and the upper ends of the frame plates on both sides of the frame are adapted to the U-shaped grooves on the corresponding sides to realize the guided sliding connection between the seat plate and the frame.

[0006] Furthermore, two long mounting holes are formed on both sides of the seat plate surface and are arranged parallel to its width direction, and the insertion part of the upper edge of the guide plate whose length is shorter than the lower end length is inserted into the long mounting hole and is welded and fixed to the edge of the long mounting hole as a whole.

[0007] Furthermore, the locking connection assembly includes multiple sets of connecting bolts and locking nuts, and a number of through holes are evenly distributed on the frame plates on both sides of the frame along their length direction, and a plurality of connecting holes corresponding to the positions of the through holes are evenly distributed on the surface of the guide plate. The multiple connecting bolts respectively pass through the corresponding connecting holes and through holes and are adapted to be connected with the locking nuts to realize adjustable position fixation between the seat plate and the frame.

[0008] Furthermore, the support seat includes a vertically arranged support plate and a rib plate symmetrically fixed on the side wall of the support plate. A U-shaped opening groove with an opening facing upward is formed on the surface of the support plate, and the sealing mold is adapted to be clamped in the U-shaped opening groove.

[0009] The advantages of this utility model compared with the prior art are:

[0010] 1. This technical solution achieves adjustment of the position of the sealing mold by providing a base plate on the frame of the hydraulic test equipment that is adjustably fixed to the frame by a locking connection assembly.

[0011] 2. This technical solution adopts the method of setting two sets of guide plates on the bottom surface of the seat plate, which are respectively inserted into the frame plates on both sides of the frame, to provide conditions for the sliding adjustment of the seat plate along the length direction of the frame;
