Description

Technical Field

[0001] This utility model relates to the field of pipe end clamping technology for plastic lining composite machines, specifically to a pipe end clamping and fixing auxiliary mechanism for plastic lining composite machines. Background Technology

[0002] A plastic-lined composite machine is a specialized piece of equipment used to combine plastic materials with metal substrates, such as steel pipes and steel plates, through a specific process to form composite products that combine the strength of metal and the corrosion resistance of plastic. In the production process of plastic-lined steel pipes, the inner plastic tube needs to be inserted into the steel pipe, and then the two ends of the steel pipe need to be fixed. Then, a fixing and limiting device is installed at both ends of the steel pipe with the plastic tube inserted to allow the inner plastic tube to come out. During the processing of the steel pipe, it is necessary to clamp and fix the steel pipe.

[0003] The auxiliary mechanism for clamping and fixing the pipe end of a plastic-lined composite machine disclosed in CN212219282U has two clamping plates and an arc-shaped groove forming a closed-loop structure to clamp the steel pipe, thereby limiting the position of the steel pipe and improving the stability of the steel pipe fixing. When the screw is reversed, the two sliding blocks move in opposite directions and slide into the receiving groove, at which point the steel pipe can be directly removed. The device has a simple fixing structure and improves the stability of the steel pipe fixing.

[0004] The auxiliary mechanism for clamping and fixing the pipe end of the plastic lining composite machine can clamp and fix the steel pipe through the set clamping plate. However, the internal arc size of the clamping plate cannot be adjusted, which means that the device can only clamp the same type of steel pipe. When it is necessary to clamp steel pipes of other sizes, the equipment needs to be changed, which is quite troublesome. Therefore, it needs to be improved. Utility Model Content

[0005] The purpose of this utility model is to provide a pipe end clamping and fixing auxiliary mechanism for a plastic lining composite machine, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a pipe end clamping and fixing auxiliary mechanism for a plastic lining composite machine, including a processing table, a clamping mechanism on the top of the processing table, a supporting mechanism on the bottom of the processing table, and a steel pipe inside the clamping mechanism; The clamping mechanism includes a mounting plate, which is fixedly connected to the left and right sides of the top of the processing table. A fixing plate is fixedly connected to the outer side of the mounting plate, and a slider is slidably connected to the inner side of the fixing plate. A rotating plate is rotatably connected to the inner side of the slider, and a lifting plate is rotatably connected to the inner side of the rotating plate. A hydraulic cylinder is fixedly connected to the bottom of the lifting plate, and a connecting plate is fixedly connected to the top of the hydraulic cylinder. The connecting plate is fixedly connected to the left and right sides of the processing table. A vertical plate is fixedly connected to the top of the slider, and a V-shaped clamping plate is fixedly connected to the inner side of the vertical plate.

[0007] Preferably, the inner side of the fixed plate is provided with a groove corresponding to the movement trajectory of the slider, and the slider is slidably connected to the inside of the groove. Through the groove, the slider can slide inside the fixed plate, and the slider can drive the V-shaped clamp to move through the vertical plate during the movement.

[0008] Preferably, there are two rotating plates, which are rotatably connected to the front and rear sides of the lifting plate respectively. When the lifting plate moves downward, the rotating plates can drive the slider to move inward to the fixed plate, so that the slider can drive the vertical plate to move.

[0009] Preferably, the steel pipe is disposed inside the V-shaped clamp, and the outer side of the steel pipe is in close contact with the inner side of the V-shaped clamp, and the steel pipe penetrates through the inner side of the mounting plate. The V-shaped clamp can clamp and fix steel pipes of different sizes.

[0010] Preferably, the support mechanism includes a protective frame, which is fixedly connected to the top of the inner side of the processing table. A drive motor is fixedly connected to the bottom of the protective frame, and a threaded rod is fixedly connected to the top of the drive motor. The top of the threaded rod is rotatably connected to the top of the inner side of the processing table. A threaded plate is threadedly connected to the outer periphery of the threaded rod. A linkage plate is fixedly connected to the top of the threaded plate, and a support plate is fixedly connected to the top of the linkage plate. The support plate is disposed at the bottom of the steel pipe, and the top of the support plate is in contact with the bottom of the steel pipe.

[0011] Preferably, there are four linkage plates, which are fixedly connected to the top of the threaded plate. When the linkage plates slide inside the processing table, they can limit the movement of the threaded plate. When the threaded plate is raised or lowered, the linkage plates can drive the support plate to be raised or lowered.

[0012] Preferably, the inner side of the processing table is provided with a sliding hole corresponding to the movement trajectory of the linkage plate, and the linkage plate is slidably connected to the inner side of the sliding hole. Through the sliding hole, the linkage plate can slide inside the processing table, so that when the linkage plate moves, it can drive the support plate to move.

[0013] Compared with the prior art, this utility model provides a pipe end clamping and fixing auxiliary mechanism for a plastic lining composite machine, which has the following beneficial effects: The plastic lining composite machine uses a pipe end clamping and fixing auxiliary mechanism. In the clamping mechanism, when the hydraulic cylinder is started, it drives the lifting plate to move up and down. The lifting plate drives the slider to slide in the groove on the inner side of the fixed plate through the rotating plate, thereby making the vertical plate and the V-shaped clamping plate move synchronously, realizing the clamping and loosening of the steel pipe, effectively preventing the steel pipe from shaking or shifting during the plastic lining composite process.

[0014] This plastic lining composite machine uses a pipe end clamping and fixing auxiliary mechanism. In the support mechanism, the drive motor drives the threaded rod to rotate, and the threaded plate moves up and down under the action of the threaded rod. Through the linkage plate, the support plate is raised and lowered. The height of the support plate can be adjusted according to the diameter and position of the steel pipe, so that its top fits tightly with the bottom of the steel pipe, which can effectively support the steel pipe and prevent the middle part from sagging or bending due to the weight of the steel pipe itself. This ensures the overall straightness of the steel pipe and is conducive to the uniform coverage of the plastic lining layer on the inner or outer wall of the steel pipe. Attached Figure Description

For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0019] This utility model provides the following technical solution: Example

[0020] Please see Figure 1-4 This utility model provides a technical solution: a pipe end clamping and fixing auxiliary mechanism for a plastic lining composite machine, including a processing table 1, a clamping mechanism 2 is provided on the top of the processing table 1, a support mechanism 4 is provided on the bottom of the processing table 1, and a steel pipe 3 is provided inside the clamping mechanism 2. The clamping mechanism 2 includes a mounting plate 27, which is fixedly connected to the top left and right sides of the processing table 1. A fixing plate 24 is fixedly connected to the outer side of the mounting plate 27. A slider 23 is slidably connected to the inner side of the fixing plate 24. A rotating plate 22 is rotatably connected to the inner side of the slider 23. A lifting plate 28 is rotatably connected to the inner side of the rotating plate 22. A hydraulic cylinder 21 is fixedly connected to the bottom of the lifting plate 28. A connecting plate 29 is fixedly connected to the top of the hydraulic cylinder 21. The connecting plate 29 is fixedly connected to the left and right sides of the processing table 1. A vertical plate 25 is fixedly connected to the top of the slider 23. A V-shaped clamping plate 26 is fixedly connected to the inner side of the vertical plate 25.

[0021] Furthermore, a groove corresponding to the movement trajectory of the slider 23 is provided on the inner side of the fixed plate 24, and the slider 23 is slidably connected inside the groove. Through the groove, the slider 23 can slide inside the fixed plate 24, and the slider 23 can drive the V-shaped clamp 26 to move through the vertical plate 25 during the movement.

[0022] Furthermore, there are two rotating plates 22, which are rotatably connected to the front and rear sides of the lifting plate 28 respectively. When the lifting plate 28 moves downward, the rotating plates 22 can drive the slider 23 to move inward to the fixed plate 24, so that the slider 23 can drive the vertical plate 25 to move.

[0023] Furthermore, the steel pipe 3 is set inside the V-shaped clamp 26, and the outer side of the steel pipe 3 is in close contact with the inner side of the V-shaped clamp 26. The steel pipe 3 also penetrates the inner side of the mounting plate 27. The V-shaped clamp 26 can clamp and fix steel pipes 3 of different sizes. Example

[0024] Please see Figure 1-4Furthermore, based on Embodiment 1, the support mechanism 4 further includes a protective frame 44, which is fixedly connected to the top of the inner side of the processing table 1. A drive motor 43 is fixedly connected to the bottom of the protective frame 44. A threaded rod 41 is fixedly connected to the top of the drive motor 43. The top of the threaded rod 41 is rotatably connected to the top of the inner side of the processing table 1. A threaded plate 42 is threadedly connected to the outer periphery of the threaded rod 41. A linkage plate 45 is fixedly connected to the top of the threaded plate 42. A support plate 46 is fixedly connected to the top of the linkage plate 45. The support plate 46 is located at the bottom of the steel pipe 3, and the top of the support plate 46 is in contact with the bottom of the steel pipe 3.

[0025] Furthermore, there are four linkage plates 45, which are fixedly connected to the top of the threaded plate 42. When the linkage plates 45 slide inside the processing table 1, they can limit the threaded plate 42. When the threaded plate 42 is raised or lowered, the linkage plates 45 can drive the support plate 46 to be raised or lowered.

[0026] Furthermore, the inner side of the processing table 1 is provided with a sliding hole corresponding to the movement trajectory of the linkage plate 45, and the linkage plate 45 is slidably connected to the inner side of the sliding hole. Through the sliding hole, the linkage plate 45 can slide inside the processing table 1, so that when the linkage plate 45 moves, it can drive the support plate 46 to move.

[0027] In actual operation, when this device is used to clamp the steel pipe 3, the steel pipe 3 is first passed through the mounting plates 27 on both sides. The operator turns on the hydraulic cylinder 21 switch, and the hydraulic cylinder 21 on the connecting plate 29 starts to work. If it is necessary to clamp the steel pipe 3, the piston rod of the hydraulic cylinder 21 retracts, which drives the lifting plate 28 to move downward. When the lifting plate 28 moves downward, it will push the rotating plate 22 to deflect at an angle, which in turn drives the slider 23 to slide inward along the groove on the inner side of the fixed plate 24, so that the V-shaped clamping plates 26 on both sides gradually approach the steel pipe 3 until the inner side of the V-shaped clamping plates 26 is tightly attached to the outer side of the steel pipe 3, thus completing the clamping and fixing of the end of the steel pipe 3. After the steel pipe 3 is clamped and fixed, the staff turns on the drive motor 43 switch, so that the drive motor 43 drives the threaded rod 41 to rotate. The threaded plate 42 will move up and down along the threaded rod 41. When the threaded plate 42 rises, it drives the support plate 46 to move upward through the linkage plate 45 until the top of the support plate 46 is tightly attached to the bottom of the steel pipe 3, thus forming effective support for the steel pipe 3. The two work together to keep the steel pipe 3 in a stable position during the plastic lining composite processing, ensuring processing quality. If it is necessary to loosen the steel pipe 3, the piston rod of the hydraulic cylinder 21 extends, the lifting plate 28 moves upward, and the slider 23 is driven to slide outward by the rotating plate 22. The V-shaped clamp 26 then separates, and the steel pipe 3 can be removed.
