Description

Technical Field

[0001] This utility model relates to the field of pressure testing technology, and in particular to an online pressure testing device for hydraulic oil pipes. Background Technology

[0002] Hydraulic hoses are the oil channels for various construction machinery and are an indispensable part of every piece of machinery. They connect various hydraulic components, ensuring the circulation of the working fluid and the transmission and output of mechanical energy, thus enabling the machinery to operate agilely and flexibly. The quality of hydraulic hoses directly affects whether the machinery can be used normally, and the pressure bearing capacity of hydraulic hoses directly affects their qualification. Testing the pressure bearing capacity of hydraulic hoses requires the use of a pressure testing device.

[0003] In related technologies, existing pressure testing machines require connecting both ends of the hydraulic oil pipe to the pressure testing head during use. Liquid is then introduced into the hydraulic oil pipe through the pressure testing head to measure the pressure of the hydraulic oil pipe. However, when the existing hydraulic oil pipe is connected to the pressure testing head, the impact force and pressure generated by the liquid flow can easily cause the hydraulic oil pipe to detach, thus affecting the pressure measurement results.

[0004] Therefore, we propose an online pressure testing device for hydraulic oil pipes to solve the above problems. Utility Model Content

[0039] In this embodiment, the sewage discharge mechanism includes a sewage discharge pipe 7 and an activated carbon adsorption net 8. One end of the sewage discharge pipe 7 is fixedly installed on one side of the sewage discharge head 6, and the activated carbon adsorption net 8 is snapped onto the inner side of the sewage discharge pipe 7.

[0040] In this embodiment, pressure measuring heads 10 are fixedly installed on the sides of the two pressure measuring bases 9 that are close to each other. External threaded grooves 11 are provided on the outer side of the two pressure measuring heads 10. Sealing heads 12 are threaded on the two pressure measuring heads 10. The same hydraulic oil pipe 21 is sleeved on the sides of the two pressure measuring heads 10 that are close to each other.

[0041] In this embodiment, the stabilizing mechanism includes a transmission assembly, a stabilizing housing 13, a linkage metal block 14, a linkage column 22, a crank assembly, and a clamp assembly. The stabilizing housing 13 is fixedly installed on one side of the pressure measuring base 9. The linkage metal block 14 is slidably sleeved on the pressure measuring head 10. The linkage metal block 14 is slidably installed on the inner side of the stabilizing housing 13. Linkage grooves are provided on both the upper and lower sides of the linkage metal block 14. Linkage columns 22 are fixedly installed on the inner side of both linkage grooves. Crank assemblies are rotatably sleeved on both linkage columns 22. The two crank assemblies are respectively connected to the corresponding clamp assemblies. The top of the stabilizing housing 13 is provided with a transmission assembly.

[0042] In this embodiment, the transmission assembly includes an electric push rod 16 and a pushing metal block 15. One side of the pushing metal block 15 is connected to one side of the linkage metal block 14. The electric push rod 16 is fixedly installed on the top of the stabilizing housing 13, and the output end of the electric push rod 16 is fixedly connected to the pushing metal block 15.

[0043] In this embodiment, the crank assembly includes two cranks 17 and two connecting posts 18. The two cranks 17 are respectively rotatably sleeved on the corresponding connecting links 22, and the connecting posts 18 are fixedly passed through one side of each of the two cranks 17.

[0044] In this embodiment, the clamping assembly includes two flipping posts 19 and two stabilizing clamps 20. Two flipping posts 19 are fixedly installed on the inner side of the stabilizing housing 13. Stabilizing clamps 20 are rotatably sleeved on both flipping posts 19. One side of each of the two stabilizing clamps 20 is rotatably connected to the corresponding connecting post 18. Both stabilizing clamps 20 clamp the same hydraulic oil pipe 21.

[0045] Working principle: When testing the pressure of hydraulic oil pipe 21, first connect both ends of hydraulic oil pipe 21 to the corresponding pressure testing head 10. When the diameter of hydraulic oil pipe 21 is larger than that of pressure testing head 10, the operator manually rotates the sealing head 12. The sealing head 12 moves along the external thread groove 11 to fill the gap between hydraulic oil pipe 21 and pressure testing head 10. After completing the initial connection, the operator starts two electric push rods 16 through the control panel. The start of the two electric push rods 16 drives the corresponding pushing metal block 15 to move. The movement of the two pushing metal blocks 15 drives the corresponding linkage metal block 14 to move. The movement of the two linkage metal blocks 14 drives the corresponding two linkage columns 22. The movement of the two linkage columns 22 on the same linkage metal block 14 drives the corresponding crank 17 to move. The movement of the two cranks 17 drives the corresponding connecting column 18 to move. The movement of the connecting column 18 drives the corresponding stabilizing clamp 20 to move. Both stabilizing clamps 20 are rotated and sleeved on the corresponding flipping column 19. Therefore, when the two stabilizing clamps 20 are affected by the thrust generated by the movement of the corresponding connecting column 18, they will flip around the corresponding flipping column 19 as the center. The two stabilizing clamps 20 clamp and stabilize the hydraulic oil pipe 21 to prevent it from falling off due to the impact of pressure and water flow during pressure testing. Then, the staff closes the cover plate 3 and starts the pressure testing machine 1 through the control panel to conduct a pressure test on the hydraulic oil pipe 21. During the operation and testing of the equipment, liquid may easily spill into the pressure testing chamber of the pressure testing machine 1. The liquid is discharged through the set drain trough, drain head 6 and drain pipe 7. When the liquid flows in the drain pipe 7, it passes through the activated carbon adsorption net 8. The activated carbon adsorption net 8 adsorbs impurities in the liquid and filters it before discharge.

[0046] The technological advancements of this invention compared to existing technologies are as follows: the hydraulic oil pipe 21 can be clamped to prevent it from falling off during pressure testing due to the impact and pressure generated by the liquid, thus increasing the practicality of the equipment and improving the stability of the connection. At the same time, the liquid generated during equipment operation or testing can be discharged and the liquid can be easily filtered to prevent it from polluting the environment, thereby increasing the environmental friendliness of the equipment.
