Description

Technical Field

[0001] This utility model relates to the field of pipe clamps, and in particular to a high-load-bearing, earthquake-resistant, external thread heavy-duty pipe clamp. Background Technology

[0002] In modern industry and construction, the installation and maintenance of heavy-duty piping systems are crucial for ensuring structural safety and proper function. Pipe clamps, as key components connecting and supporting pipelines, directly impact the stability and safety of the entire piping system with their load-bearing capacity and seismic performance. Especially in scenarios with high load-bearing and seismic requirements, traditional pipe clamp designs often struggle to meet ever-increasing performance demands, easily leading to loosening, vibration, and damage at connections, thus affecting equipment operation and potentially causing safety hazards.

[0003] Currently, various types of pipe clamps exist on the market; however, these products still have some shortcomings in terms of load-bearing capacity, vibration resistance, and ease of installation. For example, in the transportation sector, heavy-duty pipe clamps, especially those used to connect pipelines, may be subjected to vibrations from vehicles or heavy machinery. This prolonged vibration can lead to material fatigue at the connection point, thereby affecting the tightening effect of the threads. This loosening not only affects the sealing of the pipeline but may even lead to pipeline leaks or breakage, posing potential risks to production and use. Utility Model Content

[0040] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0041] This utility model provides, for example Figure 1-5 The high-load-bearing, seismic-resistant, externally threaded heavy-duty pipe clamp shown includes: a clamping device 1 for clamping a pipe; a locking device 2, which is respectively installed on both sides of the clamping device 1; and an externally threaded connector 3, which is installed on the top of the clamping device 1. The externally threaded connector 3 can be stepped and has external threads on its outer wall to allow for threaded engagement with various external connectors of different inner diameters.

[0042] The clamping device 1 includes: a clamping plate 11, the middle part of which is arc-shaped to clamp the circular pipe; and a buffer pad 12, which is wrapped inside the arc-shaped part of the clamping plate 11. The buffer pad 12 is made of rubber. Through the compression and adhesion between the buffer pad 12 and the pipe, the clamping plate 11 can provide elastic support for clamping the pipe, resulting in better shock resistance.

[0043] The locking device 2 includes: a threaded insertion mechanism 21, which is inserted and connected to the end of the clamping plate 11; a nut seat 22, which is threadedly connected to the end of the threaded insertion mechanism 21; a first positioning mechanism 23, which is sleeved on the outside of the nut seat 22 and is used to position the nut seat 22; and a second positioning mechanism 24, which is disposed between the threaded insertion mechanism 21 and the clamping plate 11 and is used to position the threaded insertion mechanism 21. The insertion of the second positioning mechanism 24 facilitates the adjustment of the threaded insertion machine. The relative position between the threaded insertion mechanism 21 and the clamping plate 11 is positioned to prevent loosening after the threaded insertion mechanism 21 rotates relative to the clamping plate 11. The first positioning mechanism 23 facilitates the positioning of the relative position between the nut seat 22 and the clamping plate 11 to prevent loosening after the nut seat 22 rotates relative to the clamping plate 11. This prevents the threads between the threaded insertion mechanism 21 and the nut seat 22 from loosening, making the fastening of the threaded insertion mechanism 21 to the two clamping devices 1 safer and more stable. It can effectively enhance the stability between the threaded insertion mechanism 21 and the nut seat 22, prevent loosening caused by relative rotation, and achieve high load-bearing capacity for the pipeline.

[0044] The threaded insertion mechanism 21 includes: a bolt rod 211, one end of which is threadedly connected to a nut seat 22, and the bolt rod 211 is slidably inserted into the clamping plate 11; and a bolt head 212, which is connected to the other end of the bolt rod 211. Through the threaded engagement between the nut seat 22 and the bolt rod 211, the relative position between the two clamping plates 11 can be fastened, so that the two clamping plates 11 can clamp the pipe relative to each other.

[0045] The first positioning mechanism 23 includes: a first fixing ring 231, which is fixedly installed on one of the clamping plates 11; and an insertion positioning component 232, which is sleeved on the outside of the nut seat 22 and inserted into the first fixing ring 231. The insertion positioning assembly 232 includes: a threaded rotating ring 2321, which is threadedly sleeved on a nut seat 22; a movable ring 2322, which is rotatably sleeved on the outside of the threaded rotating ring 2321 via a bearing; a first positioning pin 2323, one end of which is fixedly connected to the movable ring 2322, and a first fixed ring 231 has multiple positioning holes, with the first positioning pin 2323 engaging with the inner cavity of the positioning holes; and a limiting ring 2324, which is fixedly sleeved on the outside of the nut seat 22, with the first positioning pin 2323 and the limiting ring 2324 slidably inserted and connected. When the nut seat 22 is tightened and fixed, rotating the threaded rotating ring 2321 causes the threaded rotating ring 2321 to... The external thread of the nut seat 22 rotates, and the sliding interlocking between the first positioning pin 2323 and the limiting ring 2324 allows the limiting ring 2324 to limit the sliding of the first positioning pin 2323. In conjunction with the rotational connection between the moving ring 2322 and the threaded rotating ring 2321, the threaded movement of the threaded rotating ring 2321 can push the first positioning pin 2323 to move linearly in the direction of the bolt rod 211 axis, so as to push the first positioning pin 2323 to a state where it interlocks with the positioning hole. By the first positioning pin 2323 interlocking between the first fixing ring 231 and the limiting ring 2324, the relative position of the nut seat 22 and the first fixing ring 231 can be limited, thereby realizing the loosening of the nut seat 22.

[0046] The second positioning mechanism 24 includes: a second fixed ring 241, which is fixedly installed on another clamping plate 11; an inserting ring 242, which is movably sleeved on the outside of the thread inserting mechanism 21 and is located between the second fixed ring 241 and the bolt head 212; and a second positioning post 243, which is installed on both sides of the inserting ring 242. Multiple second positioning posts 243 are slidably inserted and connected to the second fixed ring 241 and the bolt head 212 respectively. By setting the second positioning post 243 at both ends on the inserting ring 242, the second positioning post 243 can be inserted simultaneously with the second fixed ring 241 and the bolt head 212, thereby facilitating the positioning of the bolt head 212 and preventing the bolt head 212 from rotating arbitrarily, so as to achieve the positioning and anti-loosening of the thread inserting mechanism 21.

[0047] Finally, it should be noted that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
