Description

Technical Field

[0001] The utility model relates to the technical field of bend pipe positioning, and more specifically, to a positioning device for bend pipe detection. Background Art

[0002] Pipelines are channels used to transport gas or liquid. There are two types of pipes: straight pipes and curved pipes. Curved pipes need to be tested and qualified before use, because the curved structure of the curved pipe is not easy to locate, which brings difficulties to the detection of the curved pipe.

[0003] In this regard, China's patent application number: CN202020596324.7 discloses a bend pipe positioning device and a bend pipe detection device using the same, wherein the bend pipe positioning device includes a base and a positioning assembly arranged on the base, wherein the positioning assembly includes a first positioning member, a second positioning member, and a third positioning member. The first positioning member is arranged on the base to fix the pipe mouth at one end of the bend pipe; the second positioning member is arranged on the base and is located on one side of the first positioning member to clamp and fix the pipe end at the other end of the bend pipe; the third positioning member is arranged on the base and is located on the other side of the first positioning member to support the top of the bend pipe in the direction of the base. The bend pipe positioning device provided by the utility model can firmly fix the bend pipe under the cooperation of the first positioning member, the second positioning member, and the third positioning member, to prevent the bend pipe from moving in the horizontal and vertical directions and rotating, thereby facilitating further detection of the bend pipe.

[0004] The device uses three sets of positioning parts to position the bent pipe. However, during operation, the positioning platform needs to be inserted upward into the bottom end of the bent pipe, and the positioning section needs to be used to support the middle of the bent pipe to fix the bent pipe. For some long bent pipes, the adjustment column needs to be adjusted to position the upper end of the bent pipe. The operation steps are relatively cumbersome, which is not conducive to the rapid positioning of the bent pipe, resulting in low detection efficiency of the bent pipe.

[0005] Therefore, in order to solve the above technical problems, the present application proposes a positioning device for bend pipe detection. Utility Model Content

A guide rod 25 is inserted into the top of the fixed column 24, and the right end of the guide rod 25 is fixedly connected to an abutment block 26. A screw hand plate 27 is movably installed on the top of the fixed column 24 through a thread, and a second slot 28 is provided on the bottom surface of the abutment block 26. By providing the first slot 22 on the fixed block 21, during installation, it is only necessary to insert the bent pipe downward into the limiting sleeve 23 and make the bent pipe fit the inner wall of the first slot 22, so that the bent pipe can be pre-positioned, and by rotating the screw hand plate 27 The screw hand plate 27 can move left and right at the upper end of the fixed column 24, and the abutment block 26 can be moved to the right close to the fixed block 21, and the outer wall of the bent pipe can fit into the second slot 28. The abutment block 26 cooperates with the fixed block 21 to firmly position the bent pipe, which is convenient to operate. The guide rod 25 can provide a guide limit for the abutment block 26 to maintain linear movement when the screw hand plate 27 rotates. By opening a circular hole 11 at the lower side of the first slot 22, the opening of the circular hole 11 can facilitate the installation of a longer bent pipe in the first slot 22 and the second slot 28, so that the lower end can pass through the detection platform 1, and the guide block 13 can move left and right on the guide rail 12, and the distance between the detection device 14 and the positioning structure 2 can be adjusted to facilitate the installation and positioning of bent pipes of different lengths on the detection platform 1, thereby improving the use experience of the device.

The detection device 14 is fixedly mounted on the guide block 13. The circular hole 11 provides space for installing a longer curved pipe on the detection platform 1.

[0031] Furthermore, the inner diameter of the limiting sleeve 23 is equal to the inner diameter of the first slot 22 . The limiting sleeve 23 cooperates with the first slot 22 to pre-position the elbow on the fixing block 21 before the abutting block 26 fits with the fixing block 21 .

[0032] Furthermore, the fixed column 24 is fixedly installed on the top surface of the detection table 1, and the guide rod 25 and the screw hand plate 27 are installed at an angle.
