[0019] Please refer to Fig. 2The outer side of the bearing 3 is wrapped with a rubber sleeve 4, the outer side of the work type sleeve 5 is wrapped with a rubber sleeve 2, the rubber sleeve 1 and the rubber sleeve 2 are attached to each other, the left and right ends of the hydraulic damping rod 2 are rotatably installed with a ball 7, the ball 7 is attached to the work type sleeve 5, and the rationality of the structure of the technical scheme is ensured.
[0020] Please refer to Figs. 2-3 The left and right ends of the shock absorber 9 are fixedly connected with an adapter 14 near the upper side, the adapter 14 is rotatably installed with a transmission arm 15 at the corresponding compensation arm 13, one end of the connecting shaft 12 is fixedly installed with a compensation arm 13 at the corresponding support arm 11, the end of the transmission arm 15 away from the adapter 14 is penetrated and slidably connected in the compensation arm 13, the lower end of the shock absorber 9 is fixedly installed with a mounting seat 10, the upper end of the mounting seat 10 is fixedly installed with a limiting piece 16 near the middle of the left and right sides, the left and right ends of the connecting shaft 12 are rotatably connected between the upper ends of the limiting pieces 16, and the upper end of the shock absorber 9 will appear fluctuation during the process of absorbing and unloading the shock force. When the upper end is lowered, the hydrogen pipe 1 and the lower end of the hydraulic damping rod 2 and other structures will be lowered, at this time, the connection between the transmission arm 15 and the adapter 14 will be lowered synchronously, and the connecting shaft 12 is limited by the limiting piece 16, so that the lower end of the compensation arm 13 will be inclined downward synchronously under the drive of the transmission arm 15, so as to drive the connecting shaft 12 to rotate inward by a certain angle. The rotation of the connecting shaft 12 can drive the support arm 11 to make the hydraulic damping rod 2, the bearing 3 and the rubber sleeve 1 contract to the middle, thereby realizing that the three groups of chuck assemblies composed of the hydraulic damping rod 2, the bearing 3 and the rubber sleeve 1 can always be attached to the work type sleeve 5. Similarly, when the upper end of the shock absorber 9 rises, the hydrogen pipe 1 and the lower end of the hydraulic damping rod 2 and other structures will rise, the two groups of chuck assemblies on the upper side will expand outward and keep attached to the work type sleeve 5, that is, the clamping and fixing effect of the device on the hydrogen pipe 1 is ensured, and the device can be adaptively adjusted with the change of the state during the vibration, which not only ensures the integrity and feasibility of the technical scheme, but also greatly improves the shock absorption and shock prevention effect of the device on the hydrogen pipe 1. In addition, when the horizontal vibration occurs, the two ends of the work type sleeve 5 will impact the hydraulic damping rod 2, so that the hydraulic damping rod 2 deforms, and then absorbs the force generated by the vibration through the hydraulic damping rod 2, further realizing the buffering and shock prevention treatment of the hydrogen pipe 1, avoiding the impact force generated by the vibration directly acting on the hydrogen pipe 1 to cause deformation and fatigue cracks.
[0021] Working principle: when installing, only need to pull the support arm 11 to drive the upper hydraulic damping rod 2, bearing 3 and other structures to the outside, then put the device on the work sleeve 5, use the three groups of hydraulic damping rod 2, bearing 3 and rubber sleeve one 4 to form a triangle structure, and form a limiting relationship with the work sleeve 5 and rubber sleeve two 6, so as to realize the clamping and fixing of hydrogen pipe 1. When the hydrogen pipe 1 is in vertical vibration, the shock absorber 9 can effectively absorb the vibration force, and the elastic force generated can also well buffer the vibration. At the same time, in the process of absorbing the shock force and unloading, the upper end of the shock absorber 9 will appear fluctuation phenomenon. When the upper end drops, the hydrogen pipe 1 and the lower end of the hydraulic damping rod 2 and other structures will drop, at this time, the connecting part of the transmission arm 15 and the adapter 14 will drop synchronously, and the connecting shaft 12 is limited by the limiting piece 16, so the lower end of the compensation arm 13 will tilt downward synchronously under the drive of the transmission arm 15, so as to drive the connecting shaft 12 to rotate inward by a certain angle. Through the rotation of the connecting shaft 12, the support arm 11 can drive the hydraulic damping rod 2, bearing 3 and rubber sleeve one 4 to shrink to the middle, so as to realize that the three groups of hydraulic damping rod 2, bearing 3 and rubber sleeve one 4 can always fit with the work sleeve 5. Similarly, when the upper end of the shock absorber 9 rises, the hydrogen pipe 1 and the lower end of the hydraulic damping rod 2 and other structures will rise, the two groups of chuck assemblies on the upper side will expand outward, and keep fit with the work sleeve 5. In addition, when the horizontal vibration occurs, the two ends of the work sleeve 5 will impact the hydraulic damping rod 2, so that the hydraulic damping rod 2 deforms, and then absorbs the force generated by the vibration through the hydraulic damping rod 2.
