Description

Technical Field

[0001] This utility model relates to the technical field of composite pipe clamping devices, and more specifically to a steel wire mesh reinforced polyethylene plastic composite pipe clamping device. Background Technology

[0002] Composite pipes (such as steel-reinforced polyethylene composite pipes and fiberglass composite pipes) are widely used in petroleum, chemical, and municipal water supply and drainage industries due to their advantages of being lightweight, corrosion-resistant, and high-strength. During pipeline installation, pipe supports, acting as clamping structures, directly affect the stability, seismic resistance, and service life of the pipeline.

[0003] Insufficient technology: After the existing composite pipe clamping device has completed the positioning of the composite pipe, the height of the clamping device is fixed. Therefore, after the installation is completed, the height of the installed pipe bracket cannot be adjusted according to the actual use requirements, which is not convenient for adjusting the height of the pipe according to the actual installation requirements. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a steel wire mesh skeleton polyethylene plastic composite pipe clamping device to solve the problems existing in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a clamping device for a steel wire mesh reinforced polyethylene plastic composite pipe, comprising an installation and positioning component, a pulling component installed at the bottom of the installation and positioning component, a clamping component fixedly connected to the bottom of the pulling component, the installation and positioning component comprising a positioning plate, positioning blocks fixedly connected to both sides of the front and back of the positioning plate, rotating positioning plates fixedly connected to both sides of the bottom of the positioning plate, threaded rods installed on the inner sides of the two rotating positioning plates, rotating handles fixedly connected to the inner sides of the threaded rods, and a convex sliding groove formed at the bottom of the positioning plate.

[0006] Furthermore, the pulling assembly includes a hexagonal sliding block with a threaded hole on its side. A support block is fixedly connected to the top of the hexagonal sliding block, and a limit block is fixedly connected to the top of the support block. A first U-shaped positioning block is fixedly connected to the bottom of the hexagonal sliding block. A first rotary positioning shaft is installed on the inner side of the first U-shaped positioning block, and a pulling rod is fixedly connected to the outer side of the first rotary positioning shaft. A positioning circular hole is provided on one side of the front of the pulling rod.

[0007] Furthermore, the clamping assembly includes a positioning shaft, a first rotating ring is installed at the middle of the outer side of the positioning shaft, a second rotating ring is installed on the front and back sides of the outer side of the positioning shaft, a clamping half-ring is fixedly connected to the outer side of both the first and second rotating rings, a connecting positioning plate is fixedly connected to the bottom of the clamping half-ring, a positioning bolt assembly is installed on the connecting positioning plate, a second U-shaped positioning block is fixedly connected to the top of the clamping half-ring, and a second rotating positioning shaft is installed on the inner side of the second U-shaped positioning block.

[0008] Furthermore, there is a clearance fit between the cross-sectional dimensions of the inner side of the convex sliding groove and the cross-sectional dimensions of the limiting block, and there is a clearance fit between the width of the bottom opening of the convex sliding groove and the width of the support block.

[0009] Furthermore, the threads on both sides of the outer side of the threaded rod are in opposite directions, and the threaded hole and the threads on the outer side of the threaded rod are mutually engaged.

[0010] Furthermore, the pull rod has rounded corners on both sides, and the center of the rounded corners on both sides of the pull rod and the center of the positioning hole are on the same straight line. The diameter of the positioning hole is clearance-fitted with the diameter of the second rotary positioning shaft, and the diameter of the second rotary positioning shaft is the same as the diameter of the first rotary positioning shaft.

[0011] Furthermore, the first U-shaped positioning block and the first rotary positioning shaft are positioned by bearings, and the pull rod is positioned by bearings with the positioning hole.

[0012] The technical effects and advantages of this utility model are as follows:

[0013] 1. In the process of positioning the composite pipe, this utility model positions the positioning shaft, then rotates the handle to move the two pulling components located outside the threaded rod away, and then pulls the two clamping half rings to drive the first rotating ring and the second rotating ring to rotate respectively, placing the composite pipe to be positioned inside the clamping half rings. Then, by reversing the above operation, the composite pipe can be positioned. Then, the two positioning bolt assemblies are positioned by the positioning bolt assembly. Finally, the equipment can be installed on the top where it needs to be installed by the cooperation of the positioning pin and the positioning block.

[0014] 2. When the height of the composite pipe needs to be adjusted, the screw rod is rotated by turning the handle, which in turn moves the two hexagonal sliding blocks closer or further away, thereby changing the height of the clamping component. This allows the height of the composite pipe to be adjusted according to the actual installation requirements after the pipe is supported, making it convenient for the user.

All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0021] Reference Figures 1 to 4 This utility model provides a clamping device for a steel wire mesh reinforced polyethylene plastic composite pipe, including a mounting and positioning component 1. A pulling component 2 is installed at the bottom of the mounting and positioning component 1, and a clamping component 3 is fixedly connected to the bottom of the pulling component 2. The mounting and positioning component 1 includes a positioning plate 101, and positioning blocks 102 are fixedly connected to both sides of the front and back of the positioning plate 101. Rotating positioning plates 103 are fixedly connected to both sides of the bottom of the positioning plate 101.

A convex sliding groove 105 is opened at the bottom of the positioning plate 101.

[0022] In a preferred embodiment, the pulling assembly 2 includes a hexagonal sliding block 201. A threaded hole 202 is provided on the side of the hexagonal sliding block 201. A support block 203 is fixedly connected to the top of the hexagonal sliding block 201. A limit block 204 is fixedly connected to the top of the support block 203. A first U-shaped positioning block 205 is fixedly connected to the bottom of the hexagonal sliding block 201. A first rotary positioning shaft 206 is installed on the inner side of the first U-shaped positioning block 205. A pulling rod 207 is fixedly connected to the outer side of the first rotary positioning shaft 206. A positioning circular hole 208 is provided on one side of the front of the pulling rod 207. (The last sentence appears to be incomplete and possibly refers to a specific action related to positioning the composite tube.) During the positioning process, the positioning shaft 301 is positioned, and then the rotating handle 106 is rotated to move the two pulling components 2 located outside the threaded rod 104 away. Then, the two clamping half rings 304 are pulled to drive the first rotating ring 302 and the second rotating ring 303 to rotate respectively. The composite tube to be positioned is placed inside the clamping half ring 304. Then, by reversing the above operation, the composite tube can be positioned. Then, the two positioning bolt assemblies 306 are positioned by the positioning bolt assembly 306. Finally, the equipment can be installed on the top where it needs to be installed by the cooperation of the positioning pin and the positioning block 102.

[0023] In a preferred embodiment, the clamping assembly 3 includes a positioning shaft 301. A first rotating ring 302 is installed at the middle of the outer side of the positioning shaft 301, and a second rotating ring 303 is installed on the front and back sides of the outer side of the positioning shaft 301. Clamping half-rings 304 are fixedly connected to the outer sides of both the first rotating ring 302 and the second rotating ring 303. A connecting positioning plate 305 is fixedly connected to the bottom of the clamping half-rings 304. A positioning bolt assembly 306 is installed on the connecting positioning plate 305. A second U-shaped positioning block 307 is fixedly connected to the top of the clamping half-rings 304, and a second rotating positioning shaft 308 is installed on the inner side of the second U-shaped positioning block 307. When it is necessary to adjust the height of the composite tube, the threaded rod 104 is rotated by rotating the rotating handle 106, which in turn causes the two hexagonal sliding blocks 201 to move closer or further away, thereby changing the height of the clamping assembly 3. This allows the height of the composite tube to be adjusted according to the actual installation requirements after the composite tube is supported, making it convenient for the user.

[0024] In a preferred embodiment, the cross-sectional dimensions of the inner side of the convex sliding groove 105 and the cross-sectional dimensions of the limiting block 204 are fitted with a clearance, and the width of the bottom opening of the convex sliding groove 105 and the width of the support block 203 are fitted with a clearance.

[0025] In a preferred embodiment, the threads on the outer sides of the threaded rod 104 are in opposite directions, and the threaded hole 202 engages with the threads on the outer side of the threaded rod 104.

[0026] In a preferred embodiment, the pull rod 207 has rounded corners on both sides, and the center of the rounded corners on both sides of the pull rod 207 and the center of the positioning hole 208 are on the same straight line. The diameter of the positioning hole 208 is clearance-fitted with the diameter of the second rotary positioning shaft 308, and the diameter of the second rotary positioning shaft 308 is the same as the diameter of the first rotary positioning shaft 206.

[0027] In a preferred embodiment, the first U-shaped positioning block 205 and the first rotary positioning shaft 206 are positioned by bearings, and the pull rod 207 is positioned by bearings with the positioning hole 208.

[0028] The working principle of this utility model is as follows: During the positioning of the composite pipe, the positioning shaft 301 is positioned, and then the rotating handle 106 is rotated to move the two pulling components 2 located outside the threaded rod 104 away. Then, the two clamping half rings 304 are pulled to drive the first rotating ring 302 and the second rotating ring 303 to rotate respectively. The composite pipe to be positioned is placed inside the clamping half ring 304. Then, by reversing the above operation, the composite pipe can be positioned. Then, the two positioning bolt components 306 are positioned by the positioning bolt components 306. Then, the equipment can be installed on the top where it needs to be installed by the cooperation of the positioning pin and the positioning block 102.

[0029] When the height of the composite pipe needs to be adjusted, the threaded rod 104 is rotated by turning the handle 106, which in turn causes the two hexagonal sliding blocks 201 to move closer or further away, thereby changing the height of the clamping assembly 3. This allows the height of the composite pipe to be adjusted according to the actual installation requirements after the composite pipe is supported, making it convenient for users to use.

[0030] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
