Description

Technical Field

[0001] This utility model relates to the field of pipeline support technology, and in particular to a pipeline suspension protection device. Background Technology

[0002] When installing pipes (such as gas pipes and water pipes), a certain distance needs to be maintained between them and the wall. Currently, most gas pipes installed on walls use column clamps. This structure requires precise fixing of the clamps according to the direction of the gas pipe, which makes the construction operation very troublesome.

[0003] Chinese Patent CN220891306U discloses a pipeline suspension protection device for gas engineering. This device employs a telescopic and adjustable suspension assembly, allowing for adjustment according to suspension height requirements. The tightening bolt engages with limiting holes on the connecting rod for convenient and quick adjustment. The circumferential array of limiting holes also allows for adjustment of the suspension angle of the clamping plate assembly. An upper and lower clamping plate, connected by a screw and a limiting nut, clamps the pipeline in the middle. Adjusting the limiting nut and screw adjusts the distance between the upper and lower clamping plates to accommodate pipelines of different sizes. An elastic rotating ball ensures soft contact with the outer wall of the pipeline, providing a degree of protection.

[0004] However, the device still has shortcomings: the calibration operation is laborious for non-vertical or non-horizontal mounting surfaces, and the device requires tools to tighten the lock nut, making it inconvenient to operate. Summary of the Invention

[0005] The technical problem this invention aims to solve is that its application scenarios are limited and its installation and operation are time-consuming and laborious.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a pipe suspension protection device, including a support rod, one end of which is hinged to an installation plate and the other end of which is hinged to a hanger rod. Both ends of the support rod are provided with tensioning components for locking the rotation angle. A movable rod is axially slidably provided at the bottom of the hanger rod, and a clamping sleeve for holding the pipe is fixedly connected to the bottom end of the movable rod.

[0023] like Figures 1-3As shown, the present invention proposes a pipe suspension protection device, which includes a support rod 1, a movable rod 9, a locking mechanism B and a drive assembly. A turntable 3 is rotatably provided at both ends of the support rod 1. Ear plates 101 are provided at both ends of the support rod 1. A rotating shaft 2 coaxial with the turntable 3 is provided on the turntable 3. The rotating shaft 2 is rotatably connected to the ear plate 101 on the corresponding side. Two sets of locking mechanisms A are provided on the support rod 1. Locking mechanism A includes a tensioning component A4, a slider A5, and a locking block 6. The tensioning component A4 includes a spring rod A. A slide groove A102 is provided on the support rod 1. The slider A5 is located within the slide groove A102 and slidably connected to its inner wall. The locking block 6 is connected to the side of the slider A5 closest to the corresponding turntable 3. Several slots 301 are arranged in a circular array around the axis of the rotating shaft 2 on the arc surface of the turntable 3. Each locking block 6 is engaged in its corresponding slot 301. The spring rod A is located within the slide groove A102. The fixed end of the spring rod A is connected to the inner wall of the slide groove A102, and the movable end of the spring rod A is connected to the side of the slider A5 furthest from the corresponding locking block 6. In operation, the two sets of locking mechanisms A lock the corresponding turntable 3 to prevent it from rotating relative to the support rod 1. The two turntables 3 are respectively connected to the mounting plate 7 and the hanging rod 8. A guide groove is provided on the boom 8, and a positioning block is provided inside the opening of the guide groove. A positioning groove is provided on the movable rod 9. The positioning block is inserted into the positioning groove of the movable rod 9 and slidably connected to its inner wall. One end of the movable rod 9 is inserted into the positioning groove and slidably connected to its inner wall. A sleeve 10 is provided at the end of the movable rod 9 away from the boom 8, and a C-shaped groove 1001 is provided on the sleeve 10. A locking mechanism B is provided on the sleeve 10. The driving assembly includes a lead screw 11, a worm gear 12, and a worm 13. The lead screw 11 is located in the guide groove and is rotatably connected to both the boom 8 and the positioning block. The lead screw 11 is helically connected to the movable rod 9. The worm gear 12 is coaxially connected to the lead screw 11. The worm 13 is rotatably connected to the boom 8 and meshes with the worm gear 12. A crank 14 is provided at the end of the worm 13 extending out of the boom 8. The locking mechanism B locks the pipe in the state where the pipe is inserted into the C-shaped groove 1001. The drive assembly includes a lead screw 11, a worm gear 12, and a worm 13. The lead screw 11 is located in a guide groove and is rotatably connected to both the lifting rod 8 and the positioning block. The lead screw 11 is helically connected to the movable rod 9. The worm gear 12 is coaxially connected to the lead screw 11. The worm 13 is rotatably connected to the lifting rod 8 and meshes with the worm gear 12. A crank 14 is provided at one end of the worm 13 extending out of the lifting rod 8. The drive assembly is mounted on the lifting rod 8 and drives the connected movable rod 9. In the working state, the drive assembly drives the movable rod 9 to slide along the length of the lifting rod 8.

[0024] In this embodiment, firstly, keep the boom 8 vertically upward, then bring the C-shaped groove 1001 on the clamp 10 of this device close to the pipe, pull up the slider B16 to raise the clamping plate 17, exposing the opening of the C-shaped groove 1001, and clamp the clamp 10 onto the pipe. Then, release the slider B16, the spring rod B releases potential energy and pushes the clamping plate 17 down, thereby clamping the pipe with the clamping plate 17. Then, adjust the orientation of the mounting plate 7 according to the actual installation scenario. During operation, push the two sets of sliders A5 simultaneously and bring them closer together. At this time, the movement restriction of the turntable 3 is released, so that the mounting plate 7 fits against the mounting surface. Then, the slider A5 is released, the spring rod A releases its potential energy and pushes the slider A5 back. The two side blocks 6 respectively engage with the corresponding slots 301 of the turntable 3 on the corresponding side, thereby restoring the rotation restriction on the turntable 3. The mounting plate 7 is installed on the mounting surface using expansion screws. If it is necessary to adjust the height of the pipe node on the current sleeve 10 at this time, the crank 14 is rotated. The crank 14 drives the worm gear 13 to rotate, and the worm gear 13 drives the worm wheel 12 and the lead screw 11 to rotate, thereby driving the movable rod 9 to rise or fall relative to the lifting rod 8. Multiple sets of this device are distributed according to the actual scene, which can further improve the support stability of the pipeline.

[0025] Example 2

[0026] like Figure 1 and Figure 3 As shown, the pipe suspension protection device proposed in this utility model, compared with the first embodiment, has an inclined plate 18 on the side of the clamping plate 17 facing the opening of the C-shaped groove 1001. The bottom surface of the inclined plate 18 is flush with the bottom edge of the clamping plate 17, and the inclined plate 18 is slidably connected to the sleeve 10.

[0027] In this embodiment, the inclined surface of the inclined plate 18 is pressed against the outer wall of the pipe, and then pressure is applied. The inclined plate 18 drives the slider B16 to rise and causes the spring rod B to retract. After the pipe enters the C-shaped groove 1001, the spring rod B releases potential energy and pushes the slider B16 to slide down and reset, thereby causing the clamping plate 17 to slide down and clamp the pipe. There is no need to manually lift the clamping plate 17, making the operation simpler and more convenient.
