Pipe fitting fixing structure of metal pipe wall coating adhesion testing device

Abstract

This utility model discloses a pipe fitting fixing structure for a metal pipe wall coating adhesion testing device, including a clamping assembly. The clamping assembly includes a bracket with a rectangular hole along its width. A bidirectional threaded rod extending along the width of the base is disposed in the rectangular hole. Threaded sleeves are fitted on different threaded sections of the bidirectional threaded rod. A clamping element one is fixedly disposed at the top of the threaded sleeve, and a clamping element two is fixedly disposed at the bottom of the threaded sleeve. Rotation of the bidirectional threaded rod causes the two threaded sleeves to move closer or further apart. When the clamping element one moves closer together, it clamps the pipe fitting, and when the clamping element two moves closer together, it clamps the crossbar. With this utility model, the operator only needs to rotate the gripping part to simultaneously lock the crossbar with the clamping element two (fixing the position of the clamping assembly) and clamp the pipe fitting with the clamping element one (fixing the pipe fitting to be tested). Switching between clamping pipe fittings of different lengths does not require disassembling bolts or using auxiliary tools.

Description

Technical Field

[0001] This utility model belongs to the field of coating testing technology, and in particular relates to the pipe fixing structure of a metal pipe wall coating adhesion testing device. Background Technology

[0002] Applying a high-temperature resistant coating to the metal pipe wall can significantly improve its overall performance in high-temperature environments. The bonding force between the coating and the substrate material is tested using a testing device to ensure the reliability and durability of the coating in actual working processes.

[0003] During the testing process, multiple test locations are often required, and different lengths of pipe fittings may also need to be tested. Traditional testing devices typically use bolts to fix pipe fittings of different lengths or change test locations when clamping them. Each adjustment requires loosening the pipe fitting, moving the clamp, locking the clamp, and then tightening the pipe fitting, which involves many steps and is time-consuming. Utility Model Content

[0004] This utility model addresses the problems in the prior art by proposing the following technical solution:

[0005] This utility model provides a pipe fitting fixing structure for a metal pipe wall coating adhesion force testing device, including: a base, on which a crossbar extending along its length is provided, and a set of clamping components are slidably disposed on the crossbar;

[0006] The clamping assembly includes a bracket with a rectangular hole extending along its width. A bidirectional threaded rod extending along the width of the base is disposed in the rectangular hole. Threaded sleeves are fitted on different threaded sections of the bidirectional threaded rod. A clamping element one is fixedly disposed at the top of the threaded sleeve, and a clamping element two is fixedly disposed at the bottom of the threaded sleeve. The bidirectional threaded rod rotates to bring the two threaded sleeves closer together or further apart. When the clamping element one comes closer together, it clamps the pipe fitting, and when the clamping element two comes closer together, it clamps the crossbar.

[0007] As a preferred embodiment of the above technical solution, one end of the bidirectional threaded rod extends out of the bracket and is provided with a gripping part.

[0008] As a preferred embodiment of the above technical solution, the bracket is n-shaped, a slider is provided at the bottom of the bracket, and a groove is provided at the top of the base corresponding to the position of the slider. The groove extends along the length of the base, and the slider slides in cooperation with the groove.

[0009] As a preferred embodiment of the above technical solution, the first clamping member is configured to have two semi-circular shapes that match the pipe fitting, and the second clamping member is configured to have a shape that matches the crossbar.

[0010] The beneficial effects of this utility model are as follows:

[0011] This utility model, by setting a synchronous clamping mechanism driven by a bidirectional threaded rod, allows the operator to simultaneously lock the two pairs of crossbars of the clamping component (fixing the position of the clamping assembly) and clamp a pair of pipes of the clamping component (fixing the pipe to be tested) by simply rotating the gripping part. When switching to clamp pipes of different lengths, there is no need to disassemble bolts or use auxiliary tools, which greatly simplifies the operation steps and improves the efficiency of disassembly and assembly.

Detailed Implementation

[0016] To make the objectives, technical solutions, and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0017] Example

[0018] like Figure 1 As shown, Figure 1 The diagram shown is a front view of the overall fixed structure in the embodiment;

[0019] This device includes:

[0020] The base 10 has a crossbar 12 extending along its length, and a set of clamping components 20 are slidably disposed on the crossbar 12.

[0021] A set of frames 11 is provided at both ends of the base 10. A crossbar 12 is fixedly installed at the position directly in front of the set of frames 11, and both ends are fixedly connected to the frame 11 on the side where it is located.

[0022] like Figure 1 In the coordinate system shown, the X direction is the length direction of the base 10.

[0023] The base 10 serves as the basic support for the entire device. The crossbar 12 is used to support and guide the sliding of the clamping assembly 20. The clamping assemblies 20 are arranged in pairs to clamp and fix the metal pipe to be tested, and can adapt to pipes of different lengths.

[0024] like Figure 1 , Figure 2 , Figure 3 As shown, Figure 2 The diagram shown is a cross-sectional view (side view) of the clamping assembly and the crossbar in the embodiment. Figure 3 The diagram shown is a schematic representation of the bracket in the embodiment (top view).

[0025] The clamping assembly 20 includes a bracket 21, on which a rectangular hole 22 is provided along the width direction. A bidirectional threaded rod 23 extending along the width direction of the base 10 is provided in the rectangular hole 22. Threaded sleeves 24 are fitted on different threaded sections of the bidirectional threaded rod 23. A clamping element 1 25 is fixedly provided at the top of the threaded sleeve 24, and a clamping element 26 is fixedly provided at the bottom of the threaded sleeve 24. The bidirectional threaded rod 23 rotates to make the two threaded sleeves 24 move closer or further apart. When the clamping element 1 25 moves closer together, it clamps the pipe fitting. When the clamping element 26 moves closer together, it clamps the crossbar 12.

[0026] like Figure 1 In the coordinate system shown, the Y direction represents the width direction of the base 10.

[0027] Clamping component 1 25 and clamping component 26 are fixed to the top and bottom ends of the threaded sleeve 24, respectively. By rotating the bidirectional threaded rod 23, clamping component 1 25 can be moved closer or further apart, thereby clamping or releasing the pipe fitting. Clamping component 26 is used to clamp or release the crossbar 12, thereby ensuring the position of the clamping assembly on the crossbar 12.

[0028] By rotating the bidirectional threaded rod 23, the locking of the second clamping component 26 to the crossbar 12 (fixing the position of the clamping assembly 20) and the clamping of the first clamping component 25 to the pipe (fixing the pipe to be tested) can be realized simultaneously. When switching to clamp pipes of different lengths, it can be quickly disassembled and assembled, which is quick and convenient.

[0029] The rectangular hole 22 has a rectangular cross-section. The threaded sleeve 24 is installed in the rectangular hole 22, and its outer contour slides in contact with the side wall of the rectangular hole 22, thereby preventing the threaded sleeve 24 from rotating synchronously (circumferentially) with the bidirectional threaded rod 23, so that it can only move along the width direction of the base 10.

[0030] The shape of clamping member 25 is set to two semi-circular shapes that match the pipe fitting, and the shape of clamping member 26 is set to match the shape of crossbar 12. In this embodiment, the cross-sectional shape of crossbar 12 is circular, so clamping member 26 is two semi-circular shapes that match it.

[0031] like Figure 3 As shown, Figure 3 The diagram shown is a schematic representation of the bracket in the embodiment (top view).

[0032] One end of the bidirectional threaded rod 23 extends out of the bracket 21 and is provided with a gripping part 231.

[0033] The grip 231 provides the operator with a convenient place to apply force, which can be a handwheel, crank, or other design to facilitate the rotation of the bidirectional threaded rod 23.

[0034] like Figure 2 As shown, Figure 2 The diagram shown is a cross-sectional view (side view) of the clamping assembly and the crossbar in the embodiment.

[0035] The bracket 21 is n-shaped, and a slider 210 is provided at the bottom of the bracket 21. A groove 101 is provided at the top of the base 10 corresponding to the position of the slider 210. The groove 101 extends along the length of the base 10, and the slider 210 slides in conjunction with the groove 101.

[0036] The n-shaped bracket 21 means that it has two vertical support legs and a crossbeam connecting the top.

[0037] This structure provides good mechanical stability and can effectively support the internal bidirectional threaded rod 23, threaded sleeve 24 and clamping components. The slider 210 slides in conjunction with the slide groove 101, allowing the entire clamping assembly 20 to slide left and right on the base 10 along the length of the base 10 and flexibly adjust its position.

[0038] Working principle: First, the metal pipe to be tested is placed between two sets of clamping components 20. At this time, clamping component one 25 is in the open state, and clamping component two 26 is not clamping the crossbar 12. The clamping components 20 can slide freely in the slide groove 101 through the slider 210, and the position is adjustable. Then, manually push any one of the clamping components 20 to make it slide along the length direction of the base 10, and adjust the distance between the two clamping components 20 to match the length of the pipe to be tested and the position of the required test area. Then, by rotating the gripping part 231, the bidirectional threaded rod 23 is driven to rotate. The two threaded sleeves 24 approach each other under the guidance of the rectangular hole 22. At this time, clamping component two 26 installed at the bottom of the threaded sleeve 24 closes and clamps the crossbar 12, so that the clamping components 20 are firmly locked in the current position and cannot slide anymore, preventing displacement during the test. At the same time, clamping component one 25 installed at the top approaches each other, and the pipe is clamped simultaneously.

[0039] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
