Description

Technical Field

[0001] This utility model relates to the field of pipeline reinforcement technology, specifically to a safety device for pipeline reinforcement and support. Background Technology

[0002] When power plant gas pipelines or boiler equipment undergo thermal displacement during operation, pipeline clamping and fixing devices are often used for auxiliary reinforcement during pipeline installation. The pipe clamps on the pipeline reinforcement device limit and fix the pipeline, thereby achieving the effect of fixing the gas pipeline during installation.

[0003] A prior art patent with publication number CN206723610U discloses a wall structure. A connecting plate is fixedly connected to the lower surface of the wall structure via a fixing device. The fixing device includes a screw, one end of which is fixedly connected to a tapered section. A sleeve is fitted onto the outer side of the screw inside the wall structure. An adjustment hole is provided at the top of the sleeve. A washer is fitted at the connection between the screw and the connecting plate. A nut, threadedly connected to the screw, is located below the washer. A damper is fixedly connected to the middle of the lower surface of the connecting plate, and a mounting block is fixedly connected to the bottom end of the damper. This safe and stable gas pipeline clamping and fixing device, by setting up the fixing device, pulls the screw outward with the nut in the fixing device, pulling the tapered section into the sleeve. The sleeve is thus expanded, allowing it to be tightly fixed to the wall. The fixing device secures the safe and stable gas pipeline clamping and fixing device to the wall.

[0004] With use, existing devices, including those mentioned above, have gradually revealed shortcomings in this technology, mainly in the following aspects:

[0005] First, existing pipe clamping devices with valves have a cumbersome structure. When it is necessary to fix the pipe, multiple operation steps are required to fix the pipe. This is cumbersome, resulting in low production efficiency and failing to guarantee the stability of the reinforcement and support for the pipe during assembly.

[0006] Secondly, because different pipes have different outer diameters, existing devices require different sized clamping fixtures to be used when clamping the pipes, which is cumbersome. Furthermore, during the replacement process, the reinforcing structure is prone to falling off, affecting the personal safety of the operators.

[0007] In conclusion, the existing technology obviously has inconveniences and defects in practical use, so it is necessary to improve it. Utility Model Content

[0008] In view of the shortcomings of the existing technology, this utility model solves the problem that the traditional pipe clamping device has a complicated structure. When it is necessary to fix the pipe, multiple operation steps are required to fix the pipe. This is cumbersome, resulting in low production efficiency. Furthermore, it cannot guarantee the stability of the reinforcement support for the pipe during the assembly process, and the reinforcement structure is prone to falling off, which affects the personal safety of the operators.

[0009] To solve the above problems, this utility model provides the following technical solution:

[0010] A safety device for reinforcing and supporting pipelines includes a slide rail, a fixed seat slidably mounted on the slide rail, a movable plate slidably mounted vertically on the fixed seat, an upper positioning wheel at the lower end of the movable plate, two side rods swinging on the fixed seat, and side positioning wheels at the lower end of the side rods. The two side positioning wheels are lower than the upper positioning wheel. The movable plate, through a drive structure, causes the two side positioning wheels to move towards each other when it descends.

[0011] As an optimized solution, the driving structure includes a driving plate fixed to the opposite side wall of the movable plate, the outer wall of the driving plate is provided with an arc-shaped guide surface, and the upper end of the side rod rubs against the arc-shaped guide surface.

[0012] As an optimized solution, the upper end of the side rod is provided with a roller, which rubs against the arc-shaped guide surface.

[0013] As an optimized solution, a side plate is fixedly connected to each side rod on the fixed base, a hinge shaft is horizontally fixed to the side plate, and a hinge hole is provided on the side rod to cooperate with the hinge shaft.

[0014] As an optimized solution, the lower end of the arc-shaped guide surface is smoothly connected to the side wall of the movable plate.

[0015] As an optimized solution, the upper positioning wheel is fixed to the lower end of the movable plate via a wheel seat.

[0016] As an optimized solution, two of the upper positioning wheels and each of the side positioning wheels are arranged coaxially side by side.

[0017] As an optimized solution, two sleeve plates are vertically and parallelly fixed to the fixed base, and the movable plate is slidably installed within the two sleeve plates along the vertical direction.

[0018] As an optimized solution, a telescopic cylinder is fixedly connected to the upper end of the fixed base, and the lower end of the telescopic cylinder is fixedly connected to the upper end of the movable plate.

[0019] As an optimized solution, a slide block is fixedly connected to the upper end of the fixed base, and a pulley supported on the slide rail is rotatably mounted on the slide block.

[0020] Compared with the prior art, the beneficial effects of this utility model are:

[0021] When clamping and positioning the pipe, the telescopic cylinder extends, causing the movable plate to move downwards. During the downward movement of the movable plate, the drive plate also moves downwards. The arc-shaped guide surface on the drive plate contacts the rollers, causing the upper end of the side rod to move outwards, and then causing the lower end of the side rod to move inwards. As the upper positioning wheel moves downwards and the two side positioning wheels retract, an equilateral triangle is formed between the upper positioning wheel and the two side positioning wheels, achieving stable clamping and fixing of the pipe. By controlling the extension length of the telescopic cylinder, pipes of different outer diameters can be clamped and positioned. This overcomes the problem of reinforcement structures falling off during the replacement of reinforcement structures in traditional technologies, ensuring the personal safety of operators.

[0022] This allows the pipe center to be fixed at the same height when fixing valves of different diameters, eliminating the need for repeated valve alignment. This reduces the use of valve fixing tools, the installation and removal of fixing screws, and the alignment of pipe centers, thus improving the assembly efficiency of pipes with valves and ensuring the stability of the reinforcement support for pipes with valves during the assembly process.

[0023] By setting up slide rails and slide blocks, the safety device used for pipeline reinforcement and support can be moved along the track, which facilitates position adjustment and pipeline transportation. Attached Figure Description

Detailed Implementation

[0027] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the present invention and should not be construed as limiting the scope of protection of the present invention.

[0028] like Figure 1 As shown, a safety device for reinforcing and supporting pipelines includes a slide rail 1, a fixed seat 2 that slides on the slide rail 1, a movable plate 5 that slides vertically on the fixed seat 2, an upper positioning wheel 14 at the lower end of the movable plate 5, two side rods 10 that swing on the fixed seat 2, and side positioning wheels 13 at the lower end of the side rods 10. The two side positioning wheels 13 are lower than the upper positioning wheel 14. The movable plate 5 is driven by a drive structure to drive the two side positioning wheels 13 to move towards each other when it descends.

[0029] The drive structure includes a drive plate 8 fixed to the opposite side wall of the movable plate 5. The outer wall of the drive plate 8 is provided with an arc-shaped guide surface 9, and the upper end of the side rod 10 rubs against the arc-shaped guide surface 9.

[0030] The upper end of the side rod 10 is provided with a roller 12, which rotatably abuts against the arc-shaped guide surface 9.

[0031] A side plate 11 is fixedly connected to each side rod 10 on the fixed base 2. A hinge shaft is horizontally fixed to the side plate 11. A hinge hole that mates with the hinge shaft is opened on the side rod 10.

[0032] The lower end of the arc-shaped guide surface 9 is smoothly connected to the side wall of the movable plate 5.

[0033] The upper positioning wheel 14 is fixed to the lower end of the movable plate 5 via the wheel seat 15.

[0034] The upper positioning wheel 14 and each side positioning wheel 13 are arranged in two parallel coaxially.

[0035] Two sleeve plates 6 are vertically and parallelly fixed to the upper edge of the fixed base 2, and the movable plate 5 is slidably installed in the two sleeve plates 6 along the vertical direction.

[0036] A telescopic cylinder 7 is fixedly connected to the upper end of the fixed base 2, and the lower end of the telescopic cylinder 7 is fixedly connected to the upper end of the movable plate 5.

[0037] A slide block 3 is fixedly connected to the upper end of the fixed base 2, and a pulley 4 supported on the slide rail 1 is rotatably mounted on the slide block 3.

[0038] The working principle of this device is as follows:

[0039] When clamping and positioning the pipe, the telescopic cylinder 7 extends, driving the movable plate 5 to move downward. During the downward movement of the movable plate 5, the drive plate 8 moves downward. The arc-shaped guide surface 9 on the drive plate 8 contacts the roller 12, causing the upper end of the side rod 10 to move outward, and then causing the lower end of the side rod 10 to move inward. As the upper positioning wheel 14 moves downward and the two side positioning wheels 13 retract, the upper positioning wheel 14 and the two side positioning wheels 13 form an equilateral triangle, achieving stable clamping and fixing of the pipe. By controlling the extension length of the telescopic cylinder 7, it is possible to clamp and position pipes with different outer diameters.

[0040] This allows the pipe center to be fixed at the same height when fixing valves of different diameters, eliminating the need for repeated valve alignment. This reduces the use of valve fixing tools, the installation and removal of fixing screws, and the alignment of pipe centers, thus improving the assembly efficiency of pipes with valves.

[0041] By setting slide rail 1 and slide block 3, the safety device used for pipeline reinforcement and support can be moved along the track, which facilitates position adjustment and valve transportation.

[0042] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model, and they should all be covered within the scope of the claims and specification of this utility model.
