Description

Technical Field

[0001] The utility model relates to the technical field of clamping devices, in particular to a clamping device for a nondestructive detector. Background Technique

[0002] Pipeline welding is widely used in the construction of pipeline systems. When pipelines are used in pipeline projects in fields such as oil transportation, gas transportation, liquid transportation, and sample transportation, the requirements for pipeline butt joint and welding are very strict. Detection instruments need to be used to detect the welded parts of pipelines. In order to facilitate the detection of pipelines, clamping devices are usually used to assist in clamping and fixing the pipelines, so as to better and more conveniently perform detection operations on the pipelines.

[0003] In a clamping device for a nondestructive detector with the Chinese utility model patent application publication specification CN219380447U, although the movable rod is driven by a manual bolt to move along the guiding sliding hole to adjust the positions of four rubber strips, change the distance between the rubber strips and the center point, so that the four rubber strips can be in contact with the outer wall of the pressure vessel, and the four rubber strips are evenly clamped and stressed, avoiding excessive single-point stress causing deformation of the pipeline and affecting the use effect of the pipeline, and better meeting the requirements for detecting and clamping special-shaped pipelines. However, it is difficult to use according to different-shaped pipelines during use, making the overall applicable range of the device relatively limited. At the same time, the width of fixing the pipeline is also relatively limited, and it is impossible to clamp and fix larger pipelines. Therefore, a clamping device for a nondestructive detector is proposed. Content of the Utility Model

[0004] The purpose of the utility model is to provide a clamping device for a nondestructive detector to solve the problems raised in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solutions:

[0006] A clamping device for a nondestructive detector includes a bottom plate. A support column is fixedly arranged at the top end of the bottom plate. A grip is fixedly arranged at the top end of the support column. A threaded groove is opened inside the bottom plate. A clamping mechanism is arranged inside the threaded groove. Fixed plates are arranged on both sides at the bottom end of the bottom plate. A fixing groove is opened at the bottom end of the fixed plate. A pushing groove is opened on one side inside the fixing groove. A fixing mechanism is arranged inside the pushing groove. A fixing block is arranged inside the fixing groove. A clamping groove is opened on one side of the fixing block. A clamping plate is fixedly arranged at the bottom end of the fixing block. One side of the clamping plate is arc-shaped.

[0007] Preferably, the clamping mechanism includes a threaded rod, a moving plate, and a handle. The threaded rod is arranged inside the threaded groove through a rotating shaft. The threads at both ends of the threaded rod are opposite. Moving plates are movably arranged on the outer sides of both ends of the threaded rod through threaded holes. The bottom end of the moving plate is fixedly connected to the fixed plate through a connecting block. A handle is fixedly arranged on the outer side of the bottom plate at one end of the rotating shaft where the threaded rod is located;

[0008] Preferably, a limiting rod is fixedly arranged above the threaded rod inside the threaded groove. The limiting rod is movably connected to the moving plate;

[0009] Preferably, the fixing mechanism includes a pull rod, a spring, and a push plate. The pull rod is movably arranged inside the push groove. A spring is arranged on the outer side of one end of the pull rod inside the push groove. A push plate is fixedly arranged on one end of the pull rod inside the fixing groove;

[0010] Preferably, one end of the pull rod passes through the push groove and is on the outer side of the fixed plate. A pull plate is fixedly arranged at one end of the pull rod on the outer side of the fixed plate;

[0011] Preferably, a positioning plate is fixedly arranged on one side inside the fixing groove.

[0012] Compared with the prior art, the beneficial effects of the present utility model are:

[0013] 1. By pulling the pull plate outwards, when the human force is greater than the acting force of the spring, the push plate can be made to leave the clamping groove, canceling the fixing effect between the fixed plate and the fixed block, which facilitates the disassembly of the clamping plate. This setting can effectively replace the appropriate clamping plate according to the different shapes of the pipes, enabling the clamping plate to better fully contact the pipes, thereby maintaining the stability of the clamping effect. At the same time, the whole device can be used for various shaped pipes, enhancing the applicability of the device.

[0014] 2. By rotating the handle, the threaded rod is driven to rotate. At this time, because the threads at both ends of the threaded rod are opposite, the moving plates at both ends can move in opposite directions. At the same time, under the action of the limiting rod, the moving plates at both ends can move horizontally along the surface of the threaded rod, thereby driving the fixed plate to move accordingly. When the clamping plates at both ends contact the pipe, stop rotating the handle. This setting can effectively control the movement of the clamping plates on both sides, firmly fixing the pipe, and can be used for pipes of different sizes, enabling it to adapt to various sized pipes, thus facilitating the detection operation.

Specific implementation manner

[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0021] Please refer to Figures 1 - 4 As shown, a technical solution provided by the present utility model:

[0022] A clamping device for a non-destructive detector, including a bottom plate 1. A support column 2 is fixedly arranged at the top end of the bottom plate 1. A grip 3 is fixedly arranged at the top end of the support column 2. A threaded groove 4 is opened inside the bottom plate 1. A clamping mechanism is arranged inside the threaded groove 4. Fixing plates 5 are arranged on both sides of the bottom end of the bottom plate 1. A fixing groove 6 is opened at the bottom end of the fixing plate 5. A pushing groove 7 is opened on one side inside the fixing groove 6. A fixing mechanism is arranged inside the pushing groove 7. A fixing block 8 is arranged inside the fixing groove 6. A clamping groove 9 is opened on one side of the fixing block 8. A clamping plate 10 is fixedly arranged at the bottom end of the fixing block 8. One side of the clamping plate 10 is arc-shaped;

[0023] Through the above solution, under the combined action of the grip 3 and the support column 2, the bottom plate 1 can be integrally moved, and at the same time, it is convenient to control the whole device. And because one side of the clamping plate 10 is arc-shaped, it can fully contact with the pipeline, increasing the contact area with the pipeline, thereby enhancing the overall fixing effect.

[0024] In this embodiment, preferably, the clamping mechanism includes a threaded rod 11, a moving plate 12 and a handle 13. The threaded rod 11 is arranged inside the threaded groove 4 through a rotating shaft. The threads at both ends of the threaded rod 11 are opposite. Moving plates 12 are movably arranged on the outer sides of both ends of the threaded rod 11 through threaded holes. The bottom end of the moving plate 12 is fixedly connected to the fixed plate 5 through a connecting block. A handle 13 is fixedly arranged on the outer side of the bottom plate 1 at one end of the rotating shaft where the threaded rod 11 is located.

[0025] Through the above solution, by rotating the handle 13, the rotation speed of the threaded rod 11 can be driven, so as to control the displacement distance of the clamping plates 10 on both sides, thereby fixing pipes of any size. The whole device can clamp and fix larger pipes, enhancing the applicability of the device, and a better stable clamping effect on the pipes can be achieved with the setting of the threaded rod 11.

[0026] In this embodiment, preferably, a limiting rod 14 is fixedly arranged above the threaded rod 11 inside the threaded groove 4. The limiting rod 14 is movably connected to the moving plate 12.

[0027] Through the above solution, the moving plate 12 can be limited and guided, so that the moving plate 12 always moves horizontally along the surface of the threaded rod 11, maintaining the accurate movement of the clamping plates 10 on both sides.

[0028] In this embodiment, preferably, the fixing mechanism includes a pull rod 15, a spring 16 and a push plate 17. The pull rod 15 is movably arranged inside the push groove 7. A spring 16 is arranged on the outer side of one end of the pull rod 15 inside the push groove 7. A push plate 17 is fixedly arranged on one end of the pull rod 15 inside the fixing groove 6.

[0029] Through the above solution, the fixing block 8 can be fixed, the stable fixing of the clamping plate 10 can be maintained, and the operation is relatively simple. The disassembly and fixing operations can be carried out quickly, which is convenient for the staff to operate by themselves and improves the practicability of the device.

[0030] In this embodiment, preferably, one end of the pull rod 15 passes through the push groove 7 and is outside the fixed plate 5. A pull plate 18 is fixedly arranged at the end of the pull rod 15 outside the fixed plate 5.

[0031] Through the above solution, with the setting of the pull plate 18, the moving distance of the pull rod 15 can be freely controlled, and when the human force is greater than the acting force of the spring 16, the fixing effect of the fixing block 8 can be effectively controlled.

[0032] In this embodiment, preferably, a positioning plate 19 is fixedly arranged on one side inside the fixing groove 6.

[0033] Through the above scheme, the fixing block 8 has a positioning effect, so that when the fixing block 8 is placed in the fixing groove 6, the position of each placement remains consistent. At the same time, under the support of the positioning plate 19, an effective interference fixation can be formed between the push plate 17, so that the fixing block 8 is better and more stably fixed in the fixing groove 6.

[0034] The clamping device for a nondestructive testing instrument of the present embodiment pulls the pull plate 18 outward. At this time, because the manpower is greater than the force of the spring 16, the push plate 17 can be separated from the card slot 9, and the fixing effect between the fixing plate 5 and the fixing block 8 is cancelled, so that the clamping plate 10 can be easily disassembled. This setting can effectively replace the appropriate clamping plate 10 according to the pipes of different shapes, so that the clamping plate 10 can better contact with the pipes, thereby maintaining the stability of the clamping effect. At the same time, the whole device can be used for pipes of various shapes, thereby enhancing the applicability of the device.

[0035] By turning the handle 13, the threaded rod 11 is driven to rotate. At this time, since the threads at both ends of the threaded rod 11 are arranged in opposite directions, the movable plates 12 at both ends can be moved in opposite directions. At the same time, under the action of the limit rod 14, the movable plates 12 at both ends can be moved horizontally along the surface of the threaded rod 11, thereby driving the fixed plate 5 to move accordingly, until the clamping plates 10 at both ends contact the pipe, and then the rotation of the handle 13 is stopped. This setting can effectively control the movement of the clamping plates 10 on both sides, so that it can firmly fix the pipe. At the same time, it can be used according to pipes of different sizes, so that it can adapt to pipes of various sizes, thereby facilitating detection operations thereon.

[0036] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected.
