Specific embodiments

[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0024] The present utility model provides an adjustable pressure pipeline support tooling as shown in Figures 1 - 4 the figure, which includes a top plate 13 and a placing plate 5. Clamping plates 14 are fixedly arranged in the middle of the mutually adjacent surfaces of the top plate 13 and the placing plate 5. The mutually adjacent surfaces of the two clamping plates 14 are both in an arc-shaped structure. During use, the pressure pipeline is placed between the top plate 13 and the placing plate 5, and the two clamping plates 14 conform to the shape of the pressure pipeline and clamp and fix the pressure pipeline. The fixing method between the top plate 13 and the placing plate 5 generally adopts a rigid fixed connection method. However, considering that the vibration generated during the transportation of gas or liquid by the pressure pipeline is much larger than that of ordinary pipelines, it is easy to cause the problem of wear and fracture of the structure of the traditional support device, greatly reducing the service life of the support device. Therefore, buffer components are arranged between the four corners of the top plate 13 and the placing plate 5 in the present utility model.

[0025] Specifically, the buffer assembly includes a threaded post 7 fixedly installed on the placement plate 5, and both ends of the threaded post 7 extend out of the upper and lower surfaces of the placement plate 5 at the same time. A second lead screw 8 is threadedly connected inside the threaded post 7, and the head of the second lead screw 8 is located below the threaded post 7. Two gaskets 11 are movably sleeved on the screw rod of the second lead screw 8. A spring 12 is fixedly connected between the two gaskets 11, and the spring 12 is sleeved on the outer ring of the screw rod. The upper gasket 11 is located below the top plate 13 and is in movable contact with the top plate 13. The screw rod of the second lead screw 8 movably passes through both side surfaces of the top plate 13, and the end passing through both side surfaces of the top plate 13 is threadedly connected with a fastening nut 9.

[0026] Among them, the spring 12 and the two gaskets 11 form a set of shock-absorbing components. When assembling this device, screw the screw rod of the second lead screw 8 into the threaded post 7 from the bottom of the placement plate 5, and make the head of the second lead screw 8 closely abut against the bottom of the threaded post 7. Then, sleeve the shock-absorbing component on the screw rod of the second lead screw 8. Next, align the four corner holes of the top plate 13 with the four screw rods respectively. Finally, tighten the top plate 13 on the shock-absorbing component with the fastening nut 9 in turn. At this time, both clamping plates 14 are in close contact with the pressure pipeline. When the pressure pipeline transports gas or liquid, the generated vibration kinetic energy is first transmitted to the two clamping plates 14, and then to the top plate 13 and the placement plate 5. Since a shock-absorbing component is installed between the top plate 13 and the placement plate 5, part of the kinetic energy is converted into the potential energy of the spring 12, thereby reducing the vibration degree of the device, avoiding the problem of wear and fracture of the device structure, improving the service life of the support device, and enhancing the installation stability of the device.

[0027] In order to avoid the problem that the fastening nut 9 slowly slides and loosens after the top plate 13 vibrates, a rubber disc 10 is movably sleeved on the outer ring of the screw rod below the fastening nut 9, and the rubber disc 10 is in movable contact with the upper surface of the top plate 13. Through the rubber disc 10, the kinetic energy of the top plate 13 is absorbed and prevented from being transmitted to the fastening nut 9.

[0028] Due to mechanical wear that may occur between the clamping plate 14 and the pressure pipeline due to vibration, a first rubber plate 15 is provided on the arc-shaped structure of the clamping plate 14. By installing the first rubber plate 15, contact between the clamping plate 14 and the pressure pipeline is avoided, and part of the kinetic energy of the vibration of the pressure pipeline can be weakened. Since the elasticity of the first rubber plate 15 weakens over time and needs to be replaced, an insertion block 16 is fixedly provided on the side of the first rubber plate 15 close to the clamping plate 14, and a slot 17 is fixedly provided on the side of the clamping plate 14 close to the first rubber plate 15. The insertion block 16 and the slot 17 are adapted to each other. A bolt 18 threadedly connected to the insertion block 16 is rotatably provided inside the slot 17. One end of the bolt 18 extends out of the outside of the clamping plate 14 movably. By rotating the bolt 18, the bolt 18 is withdrawn from the insertion block 16 and the slot 17, so as to disassemble the first rubber plate 15, and then a new first rubber plate 15 can be replaced. The operation is simple and convenient. At the same time, since the first rubber plate 15 is fixed, when the pressure pipeline needs to be flipped during the installation of the pressure pipeline, the first rubber plate 15 will not be driven to fall off the clamping plate 14.

[0029] In addition, in order to enable the device to match the installation height of the pressure pipeline, a support assembly with adjustable height is provided at the bottom of the placement plate 5. The support assembly includes a lifting plate 4 and a bottom plate 1. There are two bottom plates 1. A connecting plate 2 is fixedly provided between the two bottom plates 1. Two support seats 3 symmetrically distributed about the center line of the bottom plate 1 are fixedly provided on the top of the bottom plate 1. The lifting plate 4 is fixedly provided in the middle of the bottom of the placement plate 5. The lifting plate 4 is movably clamped between the two support seats 3. A first threaded hole is provided on the lifting plate 4, and a number of second threaded holes vertically and evenly arranged are provided on the support seats 3. A first lead screw 6 is threadedly connected between the first threaded hole and the second threaded holes at different positions and heights, and the first lead screw 6 is used to fixedly connect the first threaded hole and the second threaded holes at different positions and heights, so as to adjust the height of the lifting plate 4, and thus adjust the height of the placement plate 5, facilitating matching the installation height of the pressure pipeline and improving the flexibility of the device.

[0030] It should be noted that the length of the placement plate 5 in the horizontal direction is greater than the distance between the two bottom plates 1 in the horizontal direction. In this way, when disassembling and assembling the second lead screw 8, the bottom plate 1 will not block the installation and disassembly of the second lead screw 8. A second rubber plate 19 is fixedly provided at the bottom of the bottom plate 1. Through the second rubber plate 19, hard connection between the device and the installation table is avoided, so as to avoid the installation table being affected by the vibration of the pressure pipeline.

[0031] The overall part structure of this device is detachable, which is convenient for transportation, disassembly and assembly, and improves the practicability of the device.
