Description

Technical Field

[0001] This utility model belongs to the field of pipeline installation technology, specifically relating to an adjustable crossarm for pipeline spacing. Background Technology

[0002] Pipe crossarms are support components used to fix and support pipelines, playing a vital role in piping systems. They are typically made of steel (such as angle steel and channel steel), possessing high strength and corrosion resistance to meet the requirements of pipeline use. The structure of a pipe crossarm usually includes pipe clamps and supports. The pipe clamps secure the pipeline, while the supports bear the weight of both the clamps and the pipeline. In some designs, the pipe crossarm may also include a crossarm section welded from channel steel and base plates to further enhance its support capacity.

[0003] Existing pipe crossarms lack the ability to adjust spacing during use. Due to the diversity and complexity of piping systems, the diameter and length of pipes may vary depending on actual needs, requiring custom-made crossarms for each pipe specification. This results in poor applicability of pipe crossarms. Furthermore, existing pipe crossarms often use exposed screws with limiting plates for fixing pipes. With the screws exposed for extended periods, they come into direct contact with oxygen, moisture, and other corrosive substances in the environment, easily leading to rust on the screw surface, which may reduce their mechanical properties. To address these issues, the inventors propose an adjustable pipe spacing crossarm. Utility Model Content

[0004] This invention aims to solve the problems of existing pipe crossarms lacking adjustable spacing, having poor adaptability, and being prone to corrosion on exposed screw surfaces.

[0005] This utility model provides the following technical solution: an adjustable pipe spacing crossbeam, including a fixed plate and two sets of pipe support frames, with an upper hanging rod connected to the top of the fixed plate; The two sets of pipe support frames are each suspended below the fixed plate by a lower hanger rod; The pipe support frame includes a support plate and two pipe clamp assemblies; the support plate is connected to the lower hanger rod, and the two pipe clamp assemblies are symmetrically arranged on both sides of the lower hanger rod on the support plate. The pipe clamp assembly includes a fixed clamping block, a movable clamping block, and a mounting box. The mounting box is mounted on a support plate. A top groove is opened in the middle of the top plate of the mounting box, and a movable block is slidably connected in the top groove. The fixed clamping block is fixedly connected to the lower hanger rod. The movable clamping block is mounted on the movable block. Long grooves are opened on the left and right side plates of the mounting box, and long plates are slidably inserted in the long grooves. The long plates are fixedly connected to the movable blocks. A limit component is provided between the long plates and the support plate.

[0006] Furthermore, the limiting component includes a rod that is slidably inserted into the long plate. The support plate has circular holes spaced apart along the sliding direction of the long plate, and the rod can be inserted into any of the circular holes to limit the sliding of the long plate.

[0007] Furthermore, the fixed plate has a sliding groove, and the lower suspension rod is slidably inserted into the sliding groove; the top of the lower suspension rod is connected to two support components, which rest on the fixed plate.

[0008] Furthermore, the two supporting components on the lower suspension rod are a supporting slide plate and a telescopic rod. A vertical plate is provided on the top of the fixed plate, and the supporting slide plate is slidably inserted into the horizontal groove of the vertical plate. The telescopic rod includes a fixed sleeve and a telescopic inner rod. The fixed sleeve is fixedly connected to the lower suspension rod, and the telescopic inner rod is slidably inserted into the fixed sleeve. A tension spring connects the telescopic inner rod and the fixed sleeve. A limit plate is provided on the top of the fixed plate, and the telescopic inner rod rests on the top surface of the limit plate. The end of the telescopic inner rod is set as a hook. Limit holes are distributed at intervals along the length direction on the limit plate. The hook at the end of the telescopic inner rod is engaged in the limit holes under the action of the tension spring.

[0009] Furthermore, the section of the lower suspension rod that slides into the groove is a square rod, with the front and rear sides of the square rod slidingly fitting into the groove.

[0010] Furthermore, the insertion rod is covered by a protective shell, which is fixed to the long plate. A spring is fitted on the insertion rod, with the upper end of the spring abutting against the protective shell and the lower end abutting against the flange on the insertion rod.

[0011] Compared with the prior art, the advantages of this utility model are: This utility model provides an adjustable pipe spacing crossarm. Through the sliding of the lower suspension rod within the groove of the fixed plate, and the cooperation between the telescopic rod (fixed sleeve, telescopic inner rod, tension spring) and the limiting hole on the limiting plate, the longitudinal spacing between two sets of pipe support frames (i.e., two rows of pipes) can be easily adjusted. Through the cooperation between the moving block and the long plate in the pipe clamp assembly and the limiting assembly (insertion rod and round hole) on the support plate, the spacing between the fixed clamp and the movable clamp can be easily adjusted to adapt to different pipe diameters. The dual adjustment mechanism (lateral + longitudinal) significantly improves the crossarm's adaptability to different pipe layout requirements, solving the problems of fixed spacing and poor adaptability in traditional crossarms.

Detailed Implementation

[0014] To more clearly illustrate the technical solutions in the embodiments of this utility model or the prior art, the drawings used in the description of the embodiments or the prior art will be briefly introduced below. Obviously, the drawings described below are only some embodiments of this utility model. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort.

[0015] like Figure 1 , Figure 3 As shown: A crossbeam with adjustable pipe spacing includes a fixed plate 1 and two sets of pipe support frames. The top of the fixed plate 1 is connected to an upper suspension rod 11. The upper suspension rod 11 is connected to the building roof plate through expansion bolts at the top. The two sets of pipe support frames are each suspended below the fixed plate 1 by the lower hanger 3; The pipe support frame includes a support plate 31 and two pipe clamp assemblies; the support plate 31 is connected to the lower hanger 3, and the two pipe clamp assemblies are symmetrically arranged on both sides of the lower hanger 3 on the support plate 31. The pipe clamp assembly includes a fixed clamping block 32, a movable clamping block 310, and a mounting box 33. The mounting box 33 is mounted on the support plate 31. A top groove 34 is opened in the middle of the top plate of the mounting box 33. A movable block 35 is slidably connected in the top groove 34. The fixed clamping block 32 is fixedly connected to the lower hanging rod 3. The movable clamping block 310 is mounted on the movable block 35. Long grooves 36 are opened on the left and right side plates of the mounting box 33. Long plates 37 are slidably inserted in the long grooves 36. Long plates 37 are fixedly connected to the movable block 35. A limit component is provided between the long plates 37 and the support plate 31.

[0016] like Figure 4 As shown: The limiting component includes a rod 39, which is slidably inserted into the long plate 37. The support plate 31 has circular holes 38 spaced apart along the sliding direction of the long plate 37. The rod 39 can be inserted into any of the circular holes 38 to restrict the sliding of the long plate 37.

[0017] The insertion rod 39 is covered by a protective shell 4, which is fixed to the long plate 37. A spring 41 is fitted onto the insertion rod 39. The upper end of the spring 41 abuts against the protective shell 4, and the lower end abuts against the flange on the insertion rod 39. The protective shell 4 completely encloses the spring 41, isolating it from moisture and corrosive media.

[0018] The process of adjusting the distance between the fixed clamping block 32 and the movable clamping block 310 is as follows: pull the insert rod 39 upward to disengage it from the round hole 38 of the support plate 31, push the long plate 37 horizontally to drive the moving block 35 and the movable clamping block 310 to slide on the mounting box 33, and after adjusting to the target position, release the insert rod 39. The spring 41 pushes it to insert into the corresponding round hole 38 and lock it. The distribution distance of the round holes 38 matches the pipe diameter of several pipes used in the construction site.

[0019] The fixed plate 1 has a groove 2, and the lower suspension rod 3 is slidably inserted into the groove 2; the top of the lower suspension rod 3 is connected to two front and rear support components, which rest on the fixed plate 1 and share the lower load of the lower suspension rod 3.

[0020] like Figure 1 , Figure 2 As shown: The two supporting components on the lower suspension rod 3 are the supporting slide plate 26 and the telescopic rod. The top of the fixed plate 1 is provided with a vertical plate 27, and the supporting slide plate 26 is slidably inserted into the horizontal groove of the vertical plate 27. The telescopic rod includes a fixed sleeve 23 and a telescopic inner rod 24. The fixed sleeve 23 is fixedly connected to the lower suspension rod 3, and the telescopic inner rod 24 is slidably inserted into the fixed sleeve 23. A tension spring 25 connects the telescopic inner rod 24 and the fixed sleeve 23. The top of the fixed plate 1 is provided with a limit plate 21, and the telescopic inner rod 24 rests on the top surface of the limit plate 21. The end of the telescopic inner rod 24 is set as a hook. Limit holes 22 are distributed at intervals along the length direction on the limit plate 21. The hook at the end of the telescopic inner rod 24 is engaged in the limit hole 22 under the action of the tension spring 25. The tension spring 25 provides continuous tension to the telescopic inner rod 24, so that the hook is tightly locked in the limit hole 22, forming a self-locking mechanism.

[0021] The process of adjusting the distance between the two sets of pipe support frames is as follows: pull out the telescopic inner rod 24 so that the hook at its end disengages from the limiting hole 22 of the limiting plate 21, push the lower rod 3 horizontally along the slide groove 2, and the support slide plate 26 slides synchronously in the horizontal slide groove of the vertical plate 27. After adjusting to the target position, release the telescopic inner rod 24, and the tension spring 25 drives the hook to automatically engage with the corresponding limiting hole 22 to complete the locking.

[0022] The section of the lower suspension rod 3 that slides into the slide groove 2 is a square rod. The front and rear sides of the square rod slide against the slide groove 2 to prevent the lower suspension rod 3 from rotating.
