Description

Technical Field

[0001] This utility model relates to the field of pipe clamp technology, specifically a pipe clamp with overload protection function. Background Technology

[0002] Pipe clamps are standard components for fixing pipelines. They consist of a base plate, a cover plate, a clamp body, and bolts. They are made of various materials such as carbon steel, stainless steel, polypropylene, nylon, and aluminum alloy. During installation, they can be mounted on a guide rail, which is then welded to a foundation; alternatively, the base plate of the pipe clamp can be directly welded to a steel plate or equipment steel beam. Pipe clamps are simple, sturdy, and easy and quick to install, making them an indispensable component in pipeline construction.

[0003] The above technical conditions also have some defects: most of the existing pipe clamps are installed on a single pipe, which cannot be used for crisscrossing pipe layouts. At the same time, they are directly installed and locked with bolts, which lacks overload protection and are prone to breakage when the pipe is subjected to large stress.

[0004] Based on this, this utility model designs a pipe clamp with overload protection function to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a pipe clamp with overload protection function to solve the above-mentioned technical problems.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a pipe clamp with overload protection function, comprising a top block, a middle block, and a bottom block. A first locking seat is provided on both sides of the middle block, and a second locking seat is provided on the other two sides of the middle block. An upper locking seat is provided on both sides of the top block, and a lower locking seat is provided on both sides of the bottom block. An upper positioning hole is provided between the top block and the middle block, and a lower positioning hole is provided between the bottom block and the middle block. Mounting grooves are provided inside the first, second, upper, and lower locking seats, and mounting bolts are provided inside the mounting grooves.

[0007] By adopting the above technical solution, the modularly designed top block, middle block and bottom block work together, and the first middle locking seat and the second middle locking seat achieve multi-directional locking force distribution.

[0008] Preferably, the mounting bolt includes an internal hexagonal head, an external hexagonal nut, and a screw rod. The external hexagonal nut and the bottom of the screw rod are connected by a thread, and an overload protection structure is also provided on the screw rod.

[0009] By adopting the above technical solution, the internal hexagonal female head and the external hexagonal nut form a bidirectional force application interface. Combined with the overload protection structure integrated in the screw, a buffer mechanism is automatically triggered when the pipeline pressure exceeds the threshold.

[0010] Preferably, the overload protection structure includes an upper butterfly spring and a lower butterfly spring, with an upper pad fixedly connected to the bottom of the upper butterfly spring and a lower pad fixedly connected to the top of the lower butterfly spring, and a wave spring provided between the upper pad and the lower pad.

[0011] By adopting the above technical solution, the upper butterfly spring, the lower butterfly spring, and the wave spring form a three-level buffer system.

[0012] Preferably, the upper butterfly-shaped spring and the lower butterfly-shaped spring are arranged symmetrically.

[0013] By adopting the above technical solution, the symmetrically arranged upper and lower butterfly springs ensure uniform pressure distribution, eliminate stress concentration on one side, and extend the service life of the spring assembly.

[0014] Preferably, the bottom of the base block is also fixedly connected to a mounting plate, and four mounting holes are provided on the mounting plate.

[0015] By adopting the above technical solution, the mounting plate is fixed in a rectangular array through four mounting holes, which increases the contact area with the base and improves the resistance to vibration and displacement.

[0016] Preferably, the upper positioning hole is a circular hole and the lower positioning hole is a square hole, and the axes of the upper positioning hole and the lower positioning hole are perpendicular to each other.

[0017] By adopting the above technical solution, the circular upper positioning hole allows the pipeline to rotate and adjust, while the square lower positioning hole provides shear resistance support. The two are axially perpendicular to form a mechanical interlock, which is suitable for mixed working conditions of high-pressure fluid and rigid pipeline.

[0018] Preferably, the first locking seat is adapted to the lower locking seat, and the second locking seat is adapted to the upper locking seat.

[0019] By adopting the above technical solutions, we can ensure that the assembly accuracy error is small and avoid installation misalignment.

[0020] In summary, this application has the following beneficial technical effects: the modular three-block structure (top block, middle block, and bottom block) combined with the multi-directional locking seat design enables simultaneous fixing of pipelines at multiple angles, significantly improving space utilization; the overload protection structure, through a three-stage spring system (butterfly springs and wave springs working in tandem), can absorb high pipeline expansion, and automatically triggers a buffer mechanism when the pressure exceeds the threshold, effectively reducing the risk of pipe bursting; the vertically intersecting layout of the circular upper positioning hole and the square lower positioning hole supports both rotational conditions and provides shear resistance, making it suitable for different working conditions.

[0028] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0029] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0030] A pipe clamp with overload protection function includes a top block 1, a middle block 2, and a bottom block 3. A first locking seat 4 is provided on both sides of the middle block 2, and a second locking seat 5 is provided on the other two sides of the middle block 2. An upper locking seat 6 is provided on both sides of the top block 1, and a lower locking seat 7 is provided on both sides of the bottom block 3. An upper positioning hole 8 is provided between the top block 1 and the middle block 2, and a lower positioning hole 9 is provided between the bottom block 3 and the middle block 2. The upper positioning hole 8 and the lower positioning hole 9 are used to fix the pipes, and can lock and position two sets of pipes with different heights and angles at the same time. An installation groove 10 is provided inside the first locking seat 4, the second locking seat 5, the upper locking seat 6, and the lower locking seat 7, and an installation bolt is provided inside the installation groove 10.

[0031] Furthermore, the mounting bolt includes an internal hexagonal head 11, an external hexagonal nut 12, and a screw 15. The external hexagonal nut 12 and the bottom of the screw 15 are connected by threads. An overload protection structure 16 is also provided on the screw 15.

[0032] Furthermore, the overload protection structure 16 includes an upper butterfly spring 161 and a lower butterfly spring 162. An upper pad 163 is fixedly connected to the bottom of the upper butterfly spring 161, and a lower pad 164 is fixedly connected to the top of the lower butterfly spring 162. A corrugated spring 165 is provided between the upper pad 163 and the lower pad 164. When the bolts are installed, the two butterfly springs and the corrugated spring 165 provide preload force, which can clamp and position the pipeline. When the pipeline is overloaded, its diameter will expand. At this time, the above-mentioned elastic body can continue to be compressed and deformed, effectively absorbing the expansion amount, thereby protecting the pipeline or pipe clamp.

[0033] Furthermore, the upper butterfly spring 161 and the lower butterfly spring 162 are symmetrically arranged, which makes them have a better performance.

[0034] Furthermore, a mounting plate 13 is fixedly connected to the bottom of the base block 3. Four mounting holes 14 are provided on the mounting plate 13, which can effectively install and limit the pipe clamp.

[0035] Furthermore, the upper positioning hole 8 is a circular hole, and the lower positioning hole 9 is a square hole, with the axes of the upper positioning hole 8 and the lower positioning hole 9 being perpendicular to each other.

[0036] Furthermore, the first locking seat 4 is adapted to the lower locking seat 7, and the second locking seat 5 is adapted to the upper locking seat 6, thus achieving proper alignment and installation.

[0037] The implementation principle of this embodiment is as follows: When the pressure inside the pipeline is normal, the mounting bolt applies preload through the internal hexagonal head 11 and the external hexagonal nut 12, causing the top block 1, middle block 2 and bottom block 3 to clamp the pipeline. If the pressure exceeds the threshold, the pipeline expands and pushes the locking seat outward, causing the top block 1 and bottom block 2 to move. The upper butterfly spring 161 of the overload protection structure 16 first compresses and absorbs the initial impact, and the wave spring 165 then radially deforms to release stress. If the pressure continues to rise, the lower butterfly spring 162 completely flattens and triggers the screw 15 to slide, allowing the pipeline to expand without breaking. After the pressure returns to normal, the spring group elastically resets and restores the preload state. The entire process does not require external intervention and achieves closed-loop protection.
