[0001] The utility model relates to pipeline fixing technical field, concretely relates to a high pressure water pipeline fixing device. BACKGROUND

[0002] The high pressure water pipeline refers to the water delivery pipeline with the pipeline operation pressure above 20MPa, and due to the large pipeline pressure and the unfirm fixing of the existing commercial pipe clamp, the pipeline vibration generated during the medium delivery cannot be effectively transmitted to the foundation for dissipation, which easily causes cracks or leakage points in the pipeline weld, and the flange seal of the pipeline auxiliary valve table machine connection is easily damaged, increasing the faults and hidden dangers in the equipment use process.

[0003] According to the search, the utility model discloses a kind of high-pressure water pipe fixing structure, including first cover, water outlet module being arranged in first cover, second cover and water inlet module being arranged in second cover. Positioning groove is provided on the first cover to install water outlet module. Second cover is provided with installation groove to install water inlet module. Multiple clamping blocks are provided in second cover. U-shaped notch is provided on the clamping block to fix the water inlet module. The side of first cover installed with water outlet module is surrounded with male buckle, the clamping block in second cover is provided with limit notch matched with male buckle, and male buckle and limit notch can be clamped to position and install first cover and second cover. The disclosed high-pressure water pipe fixing structure is strong in impact resistance, high in structural strength, overcomes the welding process using stainless steel carrier as support fixing, and reduces production cost. However, the above fixing structure is too complex, and the installation is cumbersome, not suitable for large-scale application in factory, and there is certain application defect. UTILITY MODEL CONTENT

[0004] The utility model aims at disclosing a kind of high pressure water pipeline fixing device, solve the pipeline vibration and cause the crack or leakage point of pipeline weld, pipeline auxiliary valve and flange seal are easily damaged, thereby substantially reduce pipeline and auxiliary valve table failure rate and overhaul cost.

[0005] To achieve the above object, the utility model adopts the following technical scheme:

[0006] A kind of high pressure water pipeline fixing device, including two half-body's upper fixed clamp and lower fixed clamp, upper fixed clamp and lower fixed clamp are fixedly connected by bolt, lower fixed clamp bottom and pipeline support fixed connection;The inner arc surface of upper fixed clamp and lower fixed clamp is fixed with the shock-absorbing rubber pad for clamping pipeline, and multiple buffer holes are set on the shock-absorbing rubber pad along the length direction of pipeline.

[0007] The utility model has the following beneficial effects:

[0008] When the pipeline produces vibration or is subjected to impact force, the damping rubber pad arranged on the inner arc surface of the upper fixing clamp and the lower fixing clamp can be deformed first, buffer the vibration and impact received by the pipeline, and then restore the original shape to push the pipeline back to the original position; meanwhile, the damping rubber pad has a deformation energy dissipation capacity, can absorb the vibration or impact force received by the pipeline, that is, in the repeated deformation-restoration process of the damping rubber pad, the buffer hole can eliminate the stress of the pipeline, avoid the pipeline from being damaged, can prolong the service life of the pipeline, and reduce the use cost of the pipeline. The buffer hole has a deformation energy absorption effect, when the damping rubber pad is deformed due to pipeline vibration or impact, the buffer hole is extruded and expands outward, the impact energy is converted into heat and dissipated by utilizing the friction between the damping rubber pad itself and the pipe wall, and the purpose of energy dissipation and damping is achieved. BRIEF DESCRIPTION OF DRAWINGS

[0009] Figure 1 It is a structural schematic view of the utility model.

[0010] In the figure, 1 is an upper fixing clamp, 2 is a lower fixing clamp, 3 is a pipeline support, 4 is a damping rubber pad, 5 is a buffer hole, and 6 is a connecting through hole. DETAILED DESCRIPTION

[0011] The utility model will be explained further in combination with the drawings.

[0012] In the prior art, in order to avoid the pipeline from being damaged due to vibration, a support frame is usually arranged outside the pipeline, and a rubber material is arranged between the pipeline and the support frame, since the damping of the rubber material is small, and the contact between the rubber material and the support frame is rigid, it is difficult to greatly suppress the vibration of the pipeline.

[0013] Therefore, the utility model discloses a high-pressure water pipeline fixing device, which comprises two half-body upper fixing clamps 1 and lower fixing clamps 2, the upper fixing clamps 1 and the lower fixing clamps 2 are fixedly connected through bolts, and the bottom of the lower fixing clamps 2 is fixedly connected with a pipeline support 3; damping rubber pads 4 for clamping the pipeline are fixed on the inner arc surfaces of the upper fixing clamps 1 and the lower fixing clamps 2, and a plurality of buffer holes 5 are formed in the damping rubber pads 4 in the length direction of the pipeline. The length of the pipeline support 3 can be adjusted, such as a sleeve type pipeline support, and the bottom of the pipeline support 3 is provided with a connecting through hole 6.

[0014] In use, first, the pipeline support 3 is fixedly connected with the foundation by expansion bolts penetrating through the connecting through holes 6 in the bottom of the pipeline support 3; then the height of the pipeline support 3 is adjusted to ensure that the inner arc surface of the lower fixing clamp 2 is in contact with the bottom of the pipeline; finally, the upper fixing clamp 1 is installed on the lower fixing clamp 2, and the fixing bolts are tightened to ensure that the upper fixing clamp 1 and the lower fixing clamp 2 stably clamp the pipeline. When the pipeline is vibrated or impacted, the damping rubber pad 4 arranged on the inner arc surface of the upper fixing clamp 1 and the lower fixing clamp 2 can be deformed to buffer the vibration and impact received by the pipeline, and then restore the original shape to push the pipeline back to the original position; meanwhile, the damping rubber pad 4 has a deformation energy dissipation capacity and can absorb the vibration or impact received by the pipeline, that is, in the repeated deformation-restoration process of the damping rubber pad, the damping rubber pad can eliminate the stress of the pipeline by using the buffer hole 5, avoid the pipeline from being damaged due to excessive vibration, prolong the service life of the pipeline, and reduce the use cost of the pipeline. Compared with the damping rubber pad without the buffer hole, the damping and buffering dissipation capacity of the damping rubber pad disclosed by the utility model increases by several times, the buffer hole 5 is expanded outward by being extruded when the damping rubber pad 4 is deformed due to the vibration or impact of the pipeline, the impact energy is converted into heat dissipation by using the friction between the damping rubber pad itself and the pipeline wall, and the purpose of energy absorption and dissipation damping is achieved.
