Description

Technical Field

[0001] This utility model relates to the field of pipe clamp technology, and in particular to an adjustable distance pipe clamp. Background Technology

[0002] Pipe clamps are pipe fixing components. Taking the hydraulic control circuit of a certain type of gearbox as an example, the gearbox lubricating oil pipeline system, as an important part of the gearbox, plays an extremely important role in its safe and reliable operation. Especially under the condition of high-speed continuous operation of the gearbox, the lubricating oil pipeline system, especially the high-pressure oil pipes of variable pumps, can break due to pipeline vibration, seriously affecting the safe and reliable operation of the gearbox. At present, gearboxes are usually equipped with pipe clamps in some areas when they leave the factory. However, during application and installation, it is often necessary to add pipe clamps at local locations to reduce pipeline vibration. However, since the pipeline spacing is often inconsistent, it is necessary to make them on-site. Inaccurate measurement dimensions can easily lead to the inability to install pipe clamps. At the same time, the rigid pipe clamps used in the existing technology will cause the pipe clamps to be subjected to pre-tightening forces in some areas, making them prone to breakage before and after welds, in weak bending areas, and at pre-tightening points in branch pipelines.

[0003] To address the issue of significant vibration in various control oil lines and inconsistent spacing between them, pipe clamps are added between the lines to precisely assemble the pipe clamps and reduce their vibration. However, if traditional pipe clamps are used for assembly, they cannot be installed between lines with inconsistent spacing, requiring precise on-site measurement of the spacing. This measurement error cannot be guaranteed, and the clamps will gradually loosen with vibration, resulting in poor reliability. Utility Model Content

[0004] In view of the shortcomings of the prior art, the technical problem to be solved by this utility model is to provide an adjustable distance pipe clamp, which solves the problems of existing pipe clamps being difficult to adapt to inconsistent pipe spacing, having high rigidity leading to easy breakage of pipes under local stress, and having poor reliability.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] An adjustable-pitch pipe clamp is characterized by comprising multiple sets of pipe clamp groups arranged in parallel and spaced apart. Each pipe clamp group includes two oppositely arranged clamping blocks, with corresponding clamping grooves on opposite sides of the two clamping blocks. Adjacent sets of pipe clamp groups are connected in sequence by adjustable-pitch bolts, and the two clamping blocks of the two sets of pipe clamp groups at both ends are connected by locking bolts. An adjustable-pitch compression spring is provided between the clamping blocks of adjacent sets of pipe clamp groups, wherein spring grooves are respectively provided on opposite sides of the clamping blocks of adjacent sets of pipe clamp groups, and the two ends of the adjustable-pitch compression spring extend into the spring grooves and are in a compressed state under the action of the adjustable-pitch bolts.

[0007] As an optimization, the pipe clamp assembly includes two end pipe clamp assemblies and a middle pipe clamp assembly. The end pipe clamp assemblies have first connecting lugs formed on opposite ends of their two clamping blocks, with the two first connecting lugs located at adjacent ends of the two end pipe clamp assemblies. A first connecting hole for installing the locking bolt is provided at the opposite end of the two end pipe clamp assemblies, and this first connecting hole penetrates the two clamping blocks of the end pipe clamp assemblies. The middle pipe clamp assemblies have two second connecting lugs formed near both ends on opposite sides of their two clamping blocks. Second connecting holes for installing the adjusting bolt are provided on both the first and second connecting lugs. The end pipe clamp assemblies and the middle pipe clamp assemblies are sequentially connected by adjusting bolts penetrating the first and second connecting lugs. Adjacent middle pipe clamp assemblies are sequentially connected by adjusting bolts penetrating adjacent second connecting lugs.

[0008] As an optimization, the first and second connecting lugs on the same side of the end clamp assembly and the middle clamp assembly are located on the same straight line.

[0009] As an optimization, the adjustable compression spring is fitted with a clearance fit between itself and the hole wall of the spring groove.

[0010] As an optimization, the cross-section of the clamping groove is arc-shaped.

[0011] Compared with the prior art, this application has the following advantages:

[0012] This utility model uses multiple sets of pipe clamps connected in sequence, and uses locking bolts, adjustable compression springs, and adjustable bolts to form an adjustable flexible pipe clamp support system. It can adapt to the installation of pipeline systems with inconsistent pipe spacing, reduce pipeline vibration, and at the same time, because the springs between the pipe clamp sets can reduce rigidity, it can effectively reduce the pre-tightening force on the pipeline and prevent breakage. Its structure is simple, small in size, light in weight, low in cost, easy to manufacture, and convenient and quick to install. Attached Figure Description

[0015] In the figure, 1 is clamping block, 2 is locking bolt, 3 is adjusting bolt, 4 is adjusting compression spring, 5 is first connecting ear plate, 6 is second connecting ear plate, 7 is end pipe clamp group, and 8 is middle pipe clamp group. Detailed Implementation

[0016] The present invention will now be described in further detail with reference to the accompanying drawings.

[0017] See the example. Figures 1-2An adjustable-pitch pipe clamp includes four sets of pipe clamps arranged in parallel and spaced apart. Each set of pipe clamps includes two opposing clamping blocks 1. A clamping groove is formed at a corresponding position on the opposite side of the two clamping blocks 1. In this embodiment, the cross-section of the clamping groove is arc-shaped. When the two clamping blocks 1 are brought close together, the two clamping grooves can be located on the same circumference (i.e., forming a circular clamping hole, wherein the two clamping blocks 1 are either in contact with each other or have a gap). The four sets of pipe clamps are connected sequentially by adjustable-pitch bolts 3, with a gap between adjacent sets. The two clamping blocks 1 of the two sets of pipe clamps at both ends are connected by locking bolts 2. An adjustable-pitch compression spring 4 is provided between the clamping blocks 1 of adjacent sets of pipe clamps. A spring groove is formed on the opposite side of the clamping blocks 1 of adjacent sets of pipe clamps. The two ends of the adjustable-pitch compression spring 4 extend into the spring grooves on the two clamping blocks 1, respectively. The adjustable-pitch compression spring 4 is in clearance fit with the wall of the spring groove. Initially, it is in a compressed state under the action of the adjustable-pitch bolts 3.

[0018] This utility model uses multiple sets of pipe clamps connected in sequence, and uses locking bolts 2, adjusting compression springs 4, adjusting bolts 3, etc. to form an adjustable flexible pipe clamp support system. It can adapt to the installation of pipeline systems with inconsistent pipe spacing, reduce pipeline vibration, and at the same time, since the springs between the pipe clamp sets can reduce rigidity, it can effectively reduce the pre-tightening force on the pipeline and prevent breakage. Its structure is simple, small in size, light in weight, low in cost, easy to manufacture, and convenient and quick to install.

[0019] Specifically, the pipe clamp assembly includes two end pipe clamp assemblies 7 and a middle pipe clamp assembly 8. The two clamping blocks 1 of the end pipe clamp assemblies 7 have first connecting lugs 5 formed on opposite ends, and the two first connecting lugs 5 are located at adjacent ends of the two end pipe clamp assemblies 7. A first connecting hole for installing the locking bolt 2 is provided at the opposite end of the two end pipe clamp assemblies 7. This first connecting hole is located on the side of the clamping groove opposite to the middle pipe clamp assembly 9 and passes through the two clamping blocks 1 of the end pipe clamp assemblies 7. The first connecting holes on the two clamping blocks 1 are either threaded holes or through holes. When a threaded hole is used, the locking bolt 2 can be directly threaded into the two clamping blocks; when a through hole is used, the locking bolt passes through the first connecting hole and connects to a locking nut. In practice, one clamping block can have a through hole, and the other clamping block can have a threaded hole. During assembly, the locking bolt first passes through the through hole and connects threadedly to the other clamping block. Two second connecting lugs 6 are formed near the two ends of the opposite side of the two clamping blocks 1 of the middle pipe clamp assembly 8. Both the first connecting ear plate 5 and the second connecting ear plate 6 have second connecting holes for installing the adjusting bolts 3. The end pipe clamp group 7 and the middle pipe clamp group 8 are sequentially connected by the adjusting bolts 3 passing through the first connecting ear plate 5 and the second connecting ear plate 6 and the adjusting nut. Adjacent middle pipe clamp groups 8 are sequentially connected by adjusting bolts 3 passing through adjacent second connecting ear plates 6. The first connecting ear plate 5 and the second connecting ear plate 6 on the same side of the end pipe clamp group 7 and the middle pipe clamp group 8 are located on the same straight line.

[0020] like Figure 2 As shown, in this embodiment, taking a certain type of gearbox hydraulic control circuit (four-way) as an example, when the vibration of the gearbox control circuit is large and pipe clamps are needed to reduce the vibration, firstly, the first pipe is clamped with the end pipe clamp group 7, and then locked with the locking bolt 2. Then, the adjusting bolt 3 is passed through the second connecting hole on the first connecting ear plate 5 of the end pipe clamp group 7. In this embodiment, the adjusting bolt is a double-ended stud. Therefore, after the adjusting bolt is passed through the second connecting hole, the hexagonal nut is screwed in. Then, the adjusting compression spring 4 is placed in the spring groove of the clamp block 1 to complete the first part of the installation, and a mark is made. The second pipe is clamped with the middle pipe clamp group 8, and the spring groove on the clamp block 1 of the middle pipe clamp group 8 and the second connecting hole on the second connecting ear plate 6 are aligned with the first part of the compression spring and the adjusting bolt 3. Then, the adjusting nut is used to adjust the first and second pipes to the appropriate positions. Then, the compression spring and the adjusting bolt 3 are placed in the second part of the pipe clamp group to complete the second part of the installation. Install the third and fourth pipelines in sequence according to the methods corresponding to the first and second pipelines. After installation, adjust the distance again using the adjusting nut, and lock the two clamps 1 of the end pipe clamp group 7 with the locking nut until all pipelines are clamped and in a position where they cannot vibrate.

[0021] In summary, to ensure smooth assembly of all parts of the pipe clamp, this invention designs the adjusting bolt as a double-ended stud to guarantee successful installation. The adjusting bolt adjusts the distance by tightening torque, which is achieved by adjusting the distance between the various components of the pipe clamp body. Flexible constraint is achieved through spring support, while horizontal translational freedom is restricted by the locking bolts.

[0022] In practical applications, this utility model can accurately and quickly clamp and position pipelines, and can adjust the spacing between multiple pipelines. The adjustment range between each pipeline is between 0-10mm, and the total adjustment spacing is 30mm. It also has good vibration resistance, is easy to use, has a long service life, and is easy to install.
