Description

Technical Field

[0001] This utility model relates to the field of testing machine technology, specifically a hydrostatic testing machine for pipes. Background Technology

[0002] The hydrostatic testing machine for pipes is a testing device used to test thermoplastic pipes, composite pipes, etc. It is an essential testing equipment for plastic pipe manufacturers and testing institutions. It can input different parameters onto an industrial control computer based on varying temperatures, pressures, and hoop stresses of the pipe. A high-pressure pump generates high-pressure liquid, which, through a pressure control system, is delivered via a high-pressure hose to the sample in a constant-temperature chamber for a long-term hydrostatic test.

[0003] Existing pipe hydrostatic testing machines require clamps to hold and fix the pipes under test during testing. However, existing clamps often use multiple sets of bolts to fix the pipes, which is time-consuming, cumbersome, and inefficient, resulting in low efficiency and inconvenience. Therefore, we propose a pipe hydrostatic testing machine. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a pipe hydrostatic testing machine, which solves the problem that when testing pipes, the pipe hydrostatic testing machine needs to use clamps to hold and fix the pipes to be tested. However, existing clamps mostly fix the pipes with multiple sets of bolts, which is time-consuming and cumbersome, resulting in reduced work efficiency.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A hydrostatic testing machine for pipes includes a main body, a lifting plate slidably connected inside the main body, a fixed frame fixedly connected to the top of the lifting plate, a lead screw rotatably connected inside the fixed frame, a sliding plate threadedly connected to the outside of the lead screw, the sliding plate slidably connected to the fixed frame, connecting rods symmetrically fixedly connected to one side of the sliding plate, a connecting seat fixedly connected to one end of the connecting rods, and fixed seats symmetrically fixedly connected to the top of the lifting plate. Clamping plates are provided on one side of the fixed seats and one side of the connecting seats, and anti-slip pads are provided on the outside of the clamping plates. The multiple clamping plates allow for clamping and fixing of the pipes, making operation convenient and facilitating subsequent pipe testing.

[0007] Preferably, a fixed frame is fixedly connected to the top of the equipment body, and hydraulic cylinders are fixedly connected to the bottom of the fixed frame at equal intervals. A connecting frame is fixedly connected to the output end of the hydraulic cylinder. The connecting frame is fixedly connected to the lifting plate. The hydraulic cylinder drives the connecting frame to move, and the connecting frame drives the lifting plate to move.

[0008] Preferably, a worm gear is rotatably connected inside the fixed frame, and a worm wheel that works with the worm gear is fixedly connected to the outside of the lead screw. A knob is fixedly connected to one end of the worm gear, and the worm gear rotates by turning the knob, which in turn drives the lead screw to rotate via the worm wheel.

[0009] Preferably, a protective ring is fixedly connected to the top of the fixed frame, and a protective cover is threaded to one end of the protective ring. The protective ring and the protective cover can shield and protect the knob, preventing accidental contact with the knob and causing misoperation.

[0010] Preferably, both the interior of the connecting seat and the interior of the fixed seat are slidably connected to sliders. One side of the slider is fixedly connected to an insert block, and one side of the clamping plate is fixedly connected to a fixing block. The interior of the fixing block has a slot for cooperating with the insert block. The slider drives the insert block to move, so that the insert block moves into the slot, thereby locking the position of the fixing block and facilitating the quick installation of the clamping plate.

[0011] Preferably, both the interior of the connecting seat and the interior of the fixed seat are slidably connected to a slide rod, the slider is fixedly connected to the slide rod, and a spring is sleeved on the outer side of the slide rod and on one side of the slider. The slide rod drives the slider to move, and the spring can drive the slider to move and reset.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1 to 6 This utility model provides a technical solution:

[0024] A hydrostatic testing machine for pipes includes a main body 1. A lifting plate 5 is slidably connected inside the main body 1. A fixed frame 4 is fixedly connected to the top of the lifting plate 5. A lead screw 13 is rotatably connected inside the fixed frame 4. A sliding plate 16 is threadedly connected to the outside of the lead screw 13. The sliding plate 16 is slidably connected to the fixed frame 4. A connecting rod 7 is symmetrically fixedly connected to one side of the sliding plate 16. A connecting seat 10 is fixedly connected to one end of the connecting rod 7. A fixed seat 12 is symmetrically fixedly connected to the top of the lifting plate 5. Clamping plates 11 are provided on one side of the fixed seat 12 and one side of the connecting seat 10. Anti-slip pads are provided on the outside of the clamping plates 11. The sliding plate 16 moves as the lead screw 13 rotates, and the sliding plate 16 moves the connecting seat 10 via the connecting rod 7. The connecting seat 10 then moves the clamping plates 11, thereby clamping and fixing the pipe. This method is convenient to operate and facilitates subsequent testing of the pipe.

[0025] Furthermore, a fixed frame 3 is fixedly connected to the top of the equipment body 1, and hydraulic cylinders 2 are fixedly connected at equal intervals to the bottom of the fixed frame 3. A connecting frame 6 is fixedly connected to the output end of the hydraulic cylinder 2. The connecting frame 6 is fixedly connected to the lifting plate 5. The hydraulic cylinder 2 drives the connecting frame 6 to move, and the connecting frame 6 drives the lifting plate 5 to move.

[0026] Furthermore, a worm gear 14 is rotatably connected inside the fixed frame 4, and a worm wheel 15 that works with the worm gear 14 is fixedly connected to the outside of the lead screw 13. A knob 17 is fixedly connected to one end of the worm gear 14, and the worm gear 14 is rotated by the knob 17, which in turn drives the lead screw 13 to rotate through the worm wheel 15.

[0027] Furthermore, a protective ring 8 is fixedly connected to the top of the fixed frame 4, and a protective cover 9 is threaded to one end of the protective ring 8. The protective ring 8 and the protective cover 9 can shield and protect the knob 17, preventing accidental contact with the knob 17 and causing misoperation.

[0028] Furthermore, both the interior of the connecting seat 10 and the interior of the fixed seat 12 are slidably connected to sliders 20. A plug 19 is fixedly connected to one side of the slider 20, and a fixing block 22 is fixedly connected to one side of the clamping plate 11. The interior of the fixing block 22 is provided with a slot 23 that cooperates with the plug 19. The slider 20 drives the plug 19 to move, so that the plug 19 moves into the slot 23, thereby locking the position of the fixing block 22, which facilitates the quick installation of the clamping plate 11.

[0029] Furthermore, both the interior of the connecting seat 10 and the interior of the fixed seat 12 are slidably connected to a slide rod 18. The slider 20 is fixedly connected to the slide rod 18. A spring 21 is sleeved on the outside of the slide rod 18 and on one side of the slider 20. The slide rod 18 drives the slider 20 to move, and the spring 21 can drive the slider 20 to move and reset.

[0030] Working principle:

[0031] When using the pipe, if it needs to be fixed during pipe testing, place the pipe on top of the lifting plate 5, unscrew the protective cover 9, and turn the knob 17. The knob 17 drives the worm gear 14 to rotate, which in turn drives the lead screw 13 to rotate via the worm wheel 15. The rotation of the lead screw 13 drives the sliding plate 16 to move, which in turn drives the connecting seat 10 to move via the connecting rod 7. The connecting seat 10 then drives the clamping plate 11 to move, thereby clamping and fixing the pipe. The operation is convenient and facilitates subsequent pipe testing. When the clamping plate 11 needs to be replaced, pull the sliding rod 18. The sliding rod 18 drives the slider 20 to move, compressing the spring 21. The slider 20 drives the insert block 19 to move away from the slot 23, releasing the locking state of the fixing block 22. The clamping plate 11 can then be removed for easy replacement and convenient use.
