[0005] A bidirectional threaded rod is mounted on the mounting plate, with one end of the bidirectional threaded rod passing through the mounting plate and connected to a motor that drives its rotation. The bidirectional threaded rod has two thread sections, one being a right-hand thread and the other a left-hand thread. Sliding blocks that are adapted to the internal threads of the different thread sections of the bidirectional threaded rod are respectively provided. An arc-shaped clamping plate is fixedly connected to the side of the sliding block. The arc-shaped clamping plate has an arc-shaped surface adapted to the steel pipe to be tested.

[0006] A sliding groove is provided on the mounting plate and is parallel to the bidirectional threaded rod;

[0007] A slider bracket is provided in the slide groove and can slide in the slide groove. Two slider brackets are provided and correspond one-to-one with the sliding block. A cylinder is installed on the slider bracket. The telescopic end of each cylinder is connected to the arc-shaped clamping plate. The arc-shaped clamping plate is arranged opposite to the arc-shaped clamping plate provided on the sliding block, and the two form an enclosing structure.

[0008] A protective cover is slidably mounted on the mounting plate and has an opening that matches the opening of the protective cover. The protective cover and the protective cover are fitted together on the mounting plate to form a closed structure. The side wall of the protective cover is provided with an arc groove, and the arc groove and the semi-circular groove together form a structure to accommodate the steel pipe.

[0009] In a preferred embodiment of this technical solution, the cross-section of the slider bracket is inverted T-shaped, and its horizontal section is fitted into the slide groove.

[0010] In a preferred embodiment, this technical solution further includes an electric push rod, which is disposed on the mounting plate and its telescopic rod is connected to the two side walls of the protective cover.

[0023] Furthermore, it should be understood that, for ease of description, the dimensions of the various components shown in the accompanying drawings are not drawn to actual scale; for example, the thickness or width of some layers may be exaggerated relative to other layers.

[0024] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined or described in one figure, it will not need to be discussed or described in detail in the description of the subsequent figures.

[0025] In order to solve the technical problems in the background art, such as Figure 1-3 As shown, this application provides a technical solution: a steel pipe performance testing device, characterized as follows:

[0026] Mounting plate 1 is the basic structure of the entire steel pipe performance testing device, used to fix and support other components of the device. Mounting plate 1 is made of a robust material, such as steel or aluminum alloy, to ensure the stability and durability of the entire device. A protective cover 2 is fixed to mounting plate 1. One side wall of the protective cover 2 has an opening, and semi-circular slots 3 are provided on both sides. The semi-circular slots 3 are used to accommodate the steel pipe, ensuring the stability of the steel pipe during the testing process. A double-threaded rod 4 is mounted on mounting plate 1, with one end passing through mounting plate 1 and connected to a motor 5, which drives the double-threaded rod 4 to rotate. The double-threaded rod 4 is designed with two sections of threads with different directions of rotation: one right-hand thread and the other left-hand thread, to achieve tension on the steel pipe. A sliding block 6 is adapted to the internal thread on the double-threaded rod 4 and is fixedly connected to an arc-shaped clamp 7. The arc-shaped clamp 7 is designed to fit the arc-shaped surface of the steel pipe to be tested, ensuring the stability and uniform stress of the steel pipe during the testing process. A groove 8 is set on mounting plate 1 parallel to the double-threaded rod 4. The slider bracket 9 is installed in the slide groove 8 and can slide freely within it. A cylinder 10 is mounted on the slider bracket 9, and the telescopic end of the cylinder 10 is connected to an arc-shaped clamping plate 7, which is positioned opposite to the arc-shaped clamping plate 7 on the sliding block 6, forming an enclosing structure to clamp or release the steel pipe. The protective cover 11 is slidably mounted on the mounting plate 1 and has an opening that matches the opening of the protective cover 2. When the protective cover 11 and the protective cover 2 are closed, they form a sealed structure, further protecting the operator and the steel pipe. The side wall of the protective cover 11 has an arc-shaped groove 12, which, together with the semi-circular groove 3, forms a stable structure for accommodating the steel pipe.

[0027] During the inspection of the steel pipe, the pipe is first placed in the receiving structure formed by the semi-circular groove 3 and the arc groove 12. The pipe is fixed in place by the clamping of the arc-shaped clamping plate 7 controlled by the cylinder 10. The motor 5 drives the bidirectional threaded rod 4 to rotate, and the sliding block 6 moves along the thread, causing the arc-shaped clamping plate 7 to separate to both sides to stretch the steel pipe. The protective cover 2 and the protective shield 11 ensure the safety of the entire inspection process.

[0028] Furthermore, the cross-section of the slider bracket 9 is designed as an inverted T-shape, which gives it high stability and load-bearing capacity. The horizontal section of the inverted T-shape is used to engage within the slide groove 8, while the vertical section is used to connect and fix other components, such as the cylinder 10 and the arc-shaped clamping plate 7. The horizontal section of the slider bracket 9 engages within the slide groove 8, allowing it to slide freely while remaining stable. The slide groove 8 can be designed with grooves that match the horizontal section of the inverted T-shape to ensure that the slider bracket 9 can be correctly positioned and move smoothly along the slide groove 8. To ensure smooth sliding of the slider bracket 9 within the slide groove 8, lubrication measures can be implemented between the contact surfaces of the horizontal section of the slider bracket 9 and the slide groove 8, such as applying lubricating oil or using low-friction materials.

[0029] It should be noted that the electric actuator 13 is mounted on the mounting plate 1 and is used to control the movement of the protective cover 11. The electric actuator 13 provides the power for linear motion. The telescopic rod of the electric actuator 13 is directly connected to the two side walls of the protective cover 11. This design allows the telescopic action of the electric actuator 13 to be directly transmitted to the protective cover 11, thereby realizing the sliding of the protective cover 11. The main function of the electric actuator 13 is to drive the protective cover 11 to slide on the mounting plate 1. Through the telescopic movement of the electric actuator 13, the protective cover 11 can be moved to the desired position to cover or expose the steel pipe inspection area.

[0030] It is worth noting that the punch 14 includes a drill bit 15, a sleeve 16, a spring 17, and a handle 18. These components work together to achieve the function of punching holes in steel pipes. The punch 14 is located at a through hole in the side wall of the protective cover 11. The sleeve 16 passes through the through hole in the side wall of the protective cover 11, and its function is to fix and guide the drill bit 15, ensuring the stability and accuracy of the drill bit 15 during punching. The drill bit 15 is fixed inside the sleeve 16 for the actual punching operation. The two ends of the spring 17 are connected to the side wall of the protective cover 11 and one end of the sleeve 16, respectively. The spring 17 provides the necessary rebound force, allowing the drill bit 15 to quickly return to its original position after punching, ready for the next punch. The handle 18 is located at one end of the sleeve 16 for manual pulling by the operator. By pulling the handle 18, the operator can stretch the spring 17, and the drill bit 15 penetrates the steel pipe to punch a hole under the rebound force of the spring 17.

[0031] It should be noted that the guide tube 19 is installed at the semi-circular groove 3. Its main function is to guide the steel pipe smoothly into and out of the semi-circular groove 3, ensuring the correct positioning and stability of the steel pipe during the inspection process. The guide tube 19 is designed in a trumpet shape, which helps to smoothly guide the steel pipe into and out of the semi-circular groove 3. The trumpet shape causes the inlet end of the guide tube 19 to gradually taper to match the diameter of the semi-circular groove 3, thereby reducing friction between the steel pipe and the guide tube 19. The diameter of the smaller diameter end of the guide tube 19 is the same as the diameter of the semi-circular groove 3. This design ensures that the steel pipe can smoothly slide from the guide tube 19 into the semi-circular groove 3, while providing sufficient guidance.

[0032] Furthermore, a mounting groove 20 is provided on the side wall of the protective cover 11. This is a long, narrow groove used to accommodate the cylinder 10, ensuring that the cylinder 10 is stably installed within the protective cover 11. The mounting groove 20 is designed to be long and narrow, a shape that allows the cylinder 10 to be placed along the length of the groove, providing sufficient space to accommodate the movement of the cylinder 10. The length of the mounting groove 20 is the same as that of the slide rail 8. The main function of the mounting groove 20 is to provide a stable mounting platform for the cylinder 10, while allowing the cylinder 10 to move freely and unobstructed within the slide rail 8.

[0033] It is worth noting that the anti-slip layer 21 is located on the inner side of the arc-shaped clamp 7, which is the part that directly contacts the steel pipe. The function of the anti-slip layer 21 is to provide additional friction when clamping the steel pipe, preventing the steel pipe from sliding or shifting during the inspection process. The anti-slip layer 21 can be made of a material with a high coefficient of friction, such as rubber, polyurethane, or other synthetic materials, which can provide a stable anti-slip effect under different environmental conditions. The anti-slip layer 21 can be an integrally molded structure or a separate component attached to the inner surface of the arc-shaped clamp 7. Its structural design should ensure that pressure is evenly distributed when in contact with the steel pipe, increasing friction.

[0034] Although embodiments of this application have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this application, the scope of which is defined by the appended claims and their equivalents.
