[0002] Pipes are materials with a very wide range of applications. They are widely used in the industrial and agricultural fields, infrastructure construction fields and our daily lives. For example, the common water pipes and gas pipes in our daily lives, and the oil pipes and natural gas pipes in the industrial field, etc. The quality of the weld joints of pipes is related to whether the pipes are dense. Therefore, it is necessary to detect the welds. The detection methods are roughly divided into ray detection, penetrant detection, magnetic particle detection, ultrasonic detection and eddy current detection, etc. When detecting, it is necessary to support both ends of the welded pipe so that the weld is suspended for the work of spraying medicine at the weld. At present, when using the weld detection support equipment, most of them use two symmetrically arranged clamps to respectively support and position both ends of the pipe. However, the process of the current clamp holding the pipe is too cumbersome. Usually, it is necessary to continuously turn the tool or by hand to gradually complete the holding of the pipe, which is not convenient for quickly positioning the pipe. Based on the above problems, a support device for pipeline weld detection is now proposed. Content of the Utility Model

Specific implementation mode

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

[0021] Please refer to Figure 1-6 , the present invention provides a technical solution for a support device for pipeline weld detection: a support device for pipeline weld detection, comprising: a base 1, two first outer shells 2 are symmetrically installed at the top of the base 1, a plurality of slideways 17 are circumferentially opened on the outer wall of the first outer shell 2, a moving block 13 is slidably embedded in the inner cavity of the slideway 17, a connecting rod 14 is installed on the outer wall of the moving block 13, a clamping roller 15 is installed at the free end of the connecting rod 14, and when the plurality of moving blocks 13 move inward, the inner pipe can be clamped by the plurality of clamping rollers 15. At the same time, the clamping roller 15 can roll freely, and when the pipe moves axially, the clamping roller 15 can assist in rolling, thereby facilitating the position adjustment of the pipeline. A turntable 11 is rotatably installed in the inner cavity of the first outer shell 2, a gear ring 3 is also rotatably installed in the inner cavity of the first outer shell 2, and the gear ring 3 is fixedly connected to the turntable 11. A second outer shell 5 communicating with the inner cavity of the first outer shell 2 is installed at the top of the first outer shell 2, and a driving mechanism for driving the gear ring 3 to rotate is assembled in the inner cavity of the second outer shell 5.

[0022] The driving mechanism includes: a rack 6, one end of the rack 6 is slidably embedded in the inner cavity of the second housing 5, and the other end of the rack 6 extends out of the outer wall of the second housing 5. A pull ring 7 is installed at the end of the rack 6 extending out of the second housing 5 for facilitating the pulling of the rack 6. A gear 4 is rotatably installed in the inner cavity of the first housing 2. The outer wall of the gear 4 meshes with the toothed ring 3 and the rack 6 respectively. The gear 4 serves as a transmission component. When the movement of the rack 6 drives the gear 4 to rotate, the gear 4 can synchronously drive the toothed ring 3 to rotate. A fixing rod 8 is also installed in the inner cavity of the second housing 5. A sliding block 10 is installed at the top of the outer wall of the rack 6, and the sliding block 10 is slidably sleeved on the outer wall of the fixing rod 8. A spring 9 is sleeved on the outer wall of the fixing rod 8, and both ends of the spring 9 are fixedly installed on the inner wall of the second housing 5 and the outer wall of the sliding block 10 respectively. The spring 9 is a helical spring, which generates elastic deformation when being stretched or compressed and returns to its initial state after the external force is removed. Pulling the rack 6 makes the sliding block 10 move on the outer wall of the fixing rod 8, and at the same time compresses the spring 9. After the external force is removed, the self-elastic force of the spring 9 is used to drive the moving block 10 and the rack 6 to reset.

[0023] As a preferred solution, further, a plurality of inclined limiting grooves 12 are equidistantly arranged along the circumference on the outer wall of the turntable 11. A limiting post 16 is slidably embedded in the inner cavity of the limiting groove 12, and the limiting post 16 is fixedly connected to the outer wall of the moving block 13. When the turntable 11 rotates, by the limiting effect of the limiting groove 12 on the limiting post 16, the limiting post 16 drives the 13 to slide along the slideway 17.

[0024] In the above solution, through holes are provided at the central positions of the first housing 2, the toothed ring 3 and the turntable 11, and the through holes are coaxially arranged to ensure that the central axis of the pipeline is horizontal after both ends of the pipeline are clamped.

[0025] As a preferred solution, further, two sliding grooves 13a are symmetrically arranged on the outer wall of the moving block 13, and the sliding grooves 13a are slidably engaged with the inner wall of the slideway 17. The cooperation between the two ensures the stable sliding of the moving block 13 and prevents it from detaching.

[0026] The detailed connection means are well-known techniques in the art. Through the personnel in the art, all the electrical components in this case are connected to their adapted power supplies through wires, and a suitable controller should be selected according to the actual situation to meet the control requirements. The specific connection and control sequence should refer to the sequence of the electrical components working successively in the following working principle to complete the electrical connection. The detailed connection means are well-known techniques in the art. The following mainly introduces the working principle and process, and no further description of the electrical control will be made.

[0027] During use, pull the pull ring 7 to move the rack 6 outwards. At the same time, the sliding block 10 moves synchronously and compresses the spring 9. As the rack 6 moves, the gear 4 rotates accordingly, and then the toothed ring 3 starts to rotate. The toothed ring 3 drives the turntable 11 to rotate, so that the limit groove 12 rotates accordingly. By using the limit of the limit groove 12 on the limit post 16, the limit post 16 drives the moving block 13, the connecting rod 14 and the clamping roller 15 to expand outwards. Insert the pipe into the central through hole of the first housing 2. Then remove the external force. Use the elastic force of the spring 9 to reset the sliding block 10 and the rack 6. Then the gear 4 drives the toothed ring 3 and the connecting rod 14 to reset. Use each clamping roller 15 to clamp the outer wall of the pipe. Then circumferentially drag the pipe. The rolling of the clamping roller 15 can ensure that the position of the pipe is adjusted. When the weld position is appropriate, the subsequent operations can be started. In actual use, it can not only quickly realize the clamping and positioning of pipes with different diameters, make the weld position suspended, which is convenient for subsequent work, but also drag the pipe to adjust its position. This equipment has high versatility and is easy to operate.
