[0002] The laying of oil and gas pipelines is subject to geographical environment and road planning, and often a section of the pipeline needs to be suspended. The traditional method is to install a corresponding number of hard supports on the suspended section of the pipeline. After the pipeline is laid, the oil and gas field operators begin to transport oil and gas. In areas where earthquakes are frequent or when the vibration is large, the suspended pipeline has the largest amplitude, and the pipelines at both ends of the pipeline support are prone to stress fatigue and pipeline fracture, resulting in oil and gas leakage in the pipeline and causing environmental pollution. Summary of the invention

[0010] The lifting nut is threadedly fixed to the upper end of the lifting screw and is located between the elastic member and the screw stabilizing sleeve.

[0011] Furthermore, a plurality of force rods are provided circumferentially on the outer wall of the lifting nut.

[0012] Furthermore, a leg base is provided at the lower end of the leg.

[0013] Furthermore, the elastic member comprises a spring, one end of the spring facing the pipe clamp is provided with a spring base, the spring base is welded and fixed to the pipe clamp, and the other end of the spring abuts against the clamping column.

[0015] Furthermore, the clamping column is a smooth cylinder, and a clamping plate with a diameter larger than that of the clamping column is provided at the bottom.

[0016] The technical solution adopted by the utility model has the following beneficial effects:

[0017] In the present application, the distance between the pipeline and the ground is measured, the ground is roughly leveled and the support leg base is placed, and the lifting nut is turned to drive the lifting screw rod upward or downward to achieve micro-adjustment of the support height.

[0025] See also Figure 1 and Figure 2 In this embodiment, a pipeline 6 shock-absorbing support device includes a screw stabilizing sleeve 4, and a plurality of legs 2 are arranged at intervals in the circumferential direction of the outer wall; a lifting screw 3 is arranged in the screw stabilizing sleeve 4, and a clamping column 9 is arranged at the top of the lifting screw 3; one end of the elastic member is clamped to the clamping column 9 and is located at the upper end of the screw stabilizing sleeve 4; a pipeline clamp 10 is arranged at the other end of the elastic member, and accommodates and fixes the pipeline 6, and a lifting nut 5 is also arranged at the upper end of the lifting screw 3, and the lifting nut 5 is screwed and fixed to the upper end of the lifting screw 3, and is located between the elastic member and the screw stabilizing sleeve 4.

[0026] By measuring the distance between the pipeline 6 and the ground, roughly leveling the ground and placing the support leg base 1, the lifting nut 5 is rotated to drive the lifting screw 3 to move upward or downward to achieve micro-adjustment of the support height, and the upper pipeline clamp 10 is installed after the lower pipeline clamp 10 effectively supports the pipeline. Since an elastic member is provided between the lower pipeline clamp 10 and the screw stabilizing sleeve 4, when the pipeline 6 is subjected to a large-scale vibration or earthquake, the vibration of the pipeline 6 is greatly reduced, thereby avoiding the pipeline 6 from breaking; in addition, the lifting screw 3 is made of steel. In the process of adjusting the lifting screw 3 by the lifting nut 5, the gravity of the lifting screw 3 itself can ensure that the thread is effective, and the lifting screw 3 will not rotate with the rotation of the lifting nut 5.

[0027] The pipe clamp 10 includes an upper pipe clamp 10 and a lower pipe clamp 10 , the lower pipe clamp 10 is connected to the elastic member, and the upper pipe clamp 10 and the lower pipe clamp 10 are fixedly connected via a screw 11 and a nut 12 .

[0028] It should be noted that, in this embodiment, in order to facilitate the adjustment of the lifting screw 3, at least three force rods 7 are circumferentially welded and fixed to the outer wall of the lifting nut 5. By holding the end of the force rod 7 and rotating it for adjustment, the stability of the pipe 6 when adjusting its height can be ensured, and manpower can be saved and physical exertion can be reduced.

[0029] It should be understood that in the embodiment of the present invention, three legs 2 are arranged at intervals on the outer circumference of the screw stabilizing sleeve 4 to form a triangular stable support to keep the center of gravity supported by the pipe clamp 10 stable, and a leg base 1 is provided at the lower end of the leg 2. The base can be buried in the ground, or heavy objects can be pressed on the base to make the support more stable.

[0030] In this embodiment, the clamping column 9 is a smooth cylinder, and a clamping plate with a diameter larger than that of the clamping column 9 is provided at the bottom.

[0031] In this example, see Figure 1 and Figure 2 The elastic member includes a spring 8, one end of the spring 8 is provided with a spring base 13, the spring base 13 is welded and fixed to the pipe clamp 10, and the other end is sleeved outside the clamping column 9 and abuts against the clamping plate to facilitate the fixation of the spring 8. When the lifting nut 5 is rotated, since the lifting screw 3 is sleeved in the screw stabilizing sleeve 4, the lifting screw 3 can be driven to move upward or downward along the screw stabilizing sleeve 4, and the spring base 13 is clamped and fixed to the clamping column 9, and then the overall height of the elastic member and the pipe clamp 10 can be adjusted to make the support height of the pipe 6 appropriate.

[0032] Specifically, the present invention includes the following steps when implemented:

[0033] By measuring the distance between the pipeline 6 and the ground, roughly leveling the ground and placing the leg base 1, rotating the lifting nut 5 to drive the lifting screw 3 upward or downward to achieve micro-adjustment of the support height, and installing the upper pipeline clamp 10 after the lower pipeline clamp 10 effectively supports the pipeline. The suspended height of pipelines in different regions is inconsistent. According to the average height, the leg 2 can be improved to a telescopic leg 2 for convenience in actual operation.

[0034] The technical solution adopted by the utility model can buffer vibration during use, effectively protect the safety of the pipeline, and has the following beneficial effects:

[0035] 1. Practical: It is suitable for all kinds of suspended pipelines in earthquake-prone areas and can effectively protect the safety of suspended pipelines during earthquakes.

[0036] 2. Low cost: low installation cost and great shock-absorbing effect.
