Description

Technical Field

[0001] The invention belongs to the technical field of hydraulic jacking systems, and in particular relates to a hydraulic jacking system. Background Art

[0002] The hydraulic jacking system is a device that uses liquid pressure to lift heavy objects. It is mainly based on Pascal's law, that is, the pressure of a closed liquid can be transmitted in all directions without changing its magnitude. The system pressurizes the working medium such as hydraulic oil through a hydraulic pump, and then uses actuators such as hydraulic cylinders to convert pressure energy into mechanical energy, thereby generating an upward lifting force for lifting various large and heavy objects. During the pipeline welding construction process, it can cooperate with the temporary support structure at the bottom of the pipe to adjust the height difference between the pipeline and the connector, thereby achieving efficient and high-quality welding.

[0003] When the existing hydraulic jacking system is in use, due to the pipeline welding construction, multiple temporary support structures at the bottom of the pipe are required to be used in coordination with each other. Therefore, the hydraulic jacking system also needs to be composed of a main hydraulic power source, a sub-control hydraulic valve, a hydraulic pipeline and multiple hydraulic cylinders. The jacking stroke of each hydraulic cylinder is controlled by the hydraulic valve to adjust the height difference between the pipeline and the connecting head above the beam. However, when in use, the required hydraulic pipeline length is different in different usage environments, and if the excess length of the hydraulic pipeline is too long, pulling accidents are prone to occur, which will affect the normal operation of the jacking system and the normal progress of the welding construction.

[0016] 2. The present invention can well organize and store the hydraulic oil pipe between the hydraulic valve and the hydraulic cylinder through the pipe organizing component. In actual use, the length of the hydraulic oil pipe required for different working environments and geographical locations is different.

[0017] 3. The present invention provides a protective component to provide a buffer for the hydraulic oil pipe that is pulled. When the jacking system is in use, the hydraulic oil pipe is at risk of being pulled, which can easily cause accidents such as the pipeline connection falling off. The protective component can provide a buffer when the hydraulic oil pipe is pulled, so that it has a certain telescopic distance, thereby reducing the impact of external factors on the system, and can also effectively avoid the phenomenon of hydraulic oil pipe falling off between actuators.

[0027] The working principle of the present invention is as follows:

[0028] When in use, multiple hydraulic cylinders 7 are placed under multiple pipes to be supported respectively, and the temporary pipe support structure is used to control the height of the pipe to be installed through the hydraulic cylinders 7. The hydraulic power source 2 makes the multiple hydraulic cylinders 7 work by sucking and releasing oil. The hydraulic power is transmitted in the hydraulic system through the No. 1 hydraulic oil pipe 3 and the No. 2 hydraulic oil pipe 6. The distribution of hydraulic power is achieved through the hydraulic valve 4, which can adjust the pressure of different branches according to the needs of the system and control the hydraulic oil flow distributed to each actuator, so that each actuator works according to the predetermined requirements. The multiple hydraulic valves 4 are used to realize the individual control of the lifting strokes of the multiple hydraulic cylinders 7, so as to meet the requirements of different support heights during the pipeline installation and construction process. The height difference between the pipeline and the two ends of the connector is controlled by controlling different hydraulic cylinders 7, so as to ensure the subsequent installation quality.

[0029] When it is necessary to store the No. 2 hydraulic oil pipe 6, taking a pipeline sorting component as an example, first release the connection state between the No. 2 hydraulic oil pipe 6 and the hydraulic cylinder 7, and then turn the threaded rod 13 through the knob. The rotation of the threaded rod 13 will engage with the nut 12, and then move relative to the nut 12. When the threaded rod 13 moves, it will drive the No. 2 shell 15 to move through the circular plate 14, and the threaded rod 13 is still in a rotating state when moving, which will cause the No. 2 shell 15 to also perform a spiral rotation similar to a thread. The threaded rod 13 is concentrically arranged with the collecting roller 10. Therefore, when the No. 2 shell 15 spirally rotates, it does so around the collecting roller 10, and also moves along the axial direction of the collecting roller 10. When the No. 2 shell 15 spirally rotates, it will spirally wrap the No. 2 hydraulic oil pipe 6 around the collecting roller 10, thereby realizing the storage of the No. 2 hydraulic oil pipe 6, which is more in line with the actual usage scenario. At the same time, the storage is orderly, which can also reduce the No. 2 hydraulic The probability of the hydraulic oil pipe 6 being damaged is that after the storage is completed, the length of the No. 2 hydraulic oil pipe 6 between the hydraulic valve 4 and the hydraulic cylinder 7 is controlled according to actual needs, and then the connection between the No. 2 hydraulic oil pipe 6 and the hydraulic cylinder 7 is completed, so that the jacking function can be realized. During use, if the No. 2 hydraulic oil pipe 6 is pulled and is quickly pulled by external force, the No. 2 sorting wheel 21 in the No. 2 shell 15 will move. The No. 2 sorting wheel 21 drives the moving block 19 to move through the support shaft 20. The moving block 19 compresses the spring 23 and moves along the guide rod 18, thereby realizing a buffering effect. There is a certain distance between the two No. 1 sorting wheels 17 and the No. 2 sorting wheel 21. When the No. 2 hydraulic oil pipe 6 is pulled, this distance can be used as a buffer distance, so that the No. 2 hydraulic oil pipe 6 has a certain expansion and contraction space to avoid damage to the system caused by external force pulling, ensure that each actuator has a good connection state, and improve the practicality of the jacking system.
