Description

Technical Field

[0001] This utility model relates to the field of pipeline weld inspection technology, specifically a pressure pipeline weld flaw detector. Background Technology

[0002] According to patent authorization announcement number CN219084928U, a pipe weld defect detection device is disclosed. This utility model relates to the field of pipe weld detection technology. Its key technical points are: it includes a guide clamp, a pipe weld flaw detector, and a guide assembly. One end of the guide clamp is equipped with a positioning plate and is positioned on a primary welded pipe. A secondary welded pipe is welded to the end of the primary welded pipe. The scanning probe of the pipe weld flaw detector corresponds to the weld position between the primary and secondary welded pipes. The guide assembly is installed on the pipe weld flaw detector and consists of a roller seat and rollers. In actual use, by setting up the pipe weld defect detection device composed of the guide clamp, the pipe weld flaw detector, and the guide assembly, the guiding action of the guide clamp ensures that the scanning probe of the pipe weld flaw detector always corresponds to the weld position between the primary and secondary welded pipes, thereby guaranteeing the scanning flaw detection effect of the weld.

[0003] However, there is a problem with the existing technology: there is a height difference at the connection of the guide hoop. When the roller seat comes into contact with the junction of the raised guide hoop, the roller seat will be lifted up and the roller seat will drive the roller to move upward, causing the roller to separate from the surface of the welded pipe. The roller cannot drive the pipe weld flaw detector to continue to rotate and slide, so the junction of the guide hoop on the pipe surface cannot be detected by the weld flaw detector, which reduces the working effect of the weld flaw detector. Utility Model Content

[0004] The purpose of this invention is to provide a pressure pipeline weld flaw detector that solves the problem that when the guide clamp has a height difference at the connection point, the roller seat is lifted up after contacting the raised guide clamp, causing the roller to move upward and separating from the surface of the welded pipe. The roller cannot drive the pipeline weld flaw detector to continue rotating and sliding, resulting in the weld flaw detector being unable to detect the guide clamp connection point on the pipe surface, thus reducing the working effect of the weld flaw detector.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a pressure pipeline weld flaw detector, comprising a ring rail, a round rod assembly slidably connected to the surface of the ring rail, a clamping block fixedly connected to the inner side of the round rod assembly, a pressure pipeline body disposed on the inner side of the clamping block, a spring sleeved on the surface of the round rod assembly, the surface of the spring fixedly connected to the surface of the ring rail, the other side of the spring fixedly connected to the surface of the round rod assembly, a weld flaw detector body disposed on the top right side of the ring rail, and a sliding mechanism fixedly connected to the surface of the weld flaw detector body.

[0006] Preferably, the sliding mechanism includes a sliding frame, which is fixedly connected to the surface of the weld flaw detector body. A limiting wheel is movably connected to the top left side of the sliding frame. A limiting rail is fixedly connected to the surface of the ring rail, and the surface of the limiting rail contacts the inner wall of the limiting wheel. A sliding wheel is movably connected to the bottom left side of the sliding frame, and the surface of the sliding wheel contacts the inner wall of the ring rail.

[0007] Preferably, a handle is fixedly connected to the right side of the sliding frame, and the handle is located at the bottom of the weld flaw detector body.

[0008] Preferably, a reinforcing block is fixedly connected to the right side of the sliding frame, and the inner wall of the reinforcing block is fixedly connected to the surface of the handle.

[0009] Preferably, a rubber sleeve is fitted on the right side of the handle surface, and the rubber sleeve is located at the bottom of the pressure pipe body.

[0010] Preferably, a triangular rib is fixedly connected to the bottom of the sliding frame, and the triangular rib is located on the right side of the limiting rail.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model achieves stable clamping of pressure pipelines of different specifications by adding structures such as ring rails and round rods to the pressure pipeline body, thereby improving the versatility of the equipment.

[0012] 2. This utility model adds a ring rail or other structure to the pressure pipeline body.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figure 1-4 A pressure pipeline weld flaw detector includes a ring rail 1, a set of round rods slidably connected to the surface of the ring rail 1, a clamping block 3 fixedly connected to the inner side of the round rods 2, a pressure pipeline body 4 disposed inside the clamping block 3, a spring 5 sleeved on the surface of the round rods 2, the surface of the spring 5 fixedly connected to the surface of the ring rail 1, the other side of the spring 5 fixedly connected to the surface of the round rods 2, and a weld flaw detector body 6 disposed at the top right side of the ring rail 1, with a sliding mechanism fixedly connected to the surface of the weld flaw detector body 6.

[0017] Please see Figure 1-4 The sliding mechanism includes a sliding frame 71, which is fixedly connected to the surface of the weld flaw detector body 6. A limiting wheel 72 is movably connected to the top left side of the sliding frame 71. A limiting rail 73 is fixedly connected to the surface of the ring rail 1. The surface of the limiting rail 73 contacts the inner wall of the limiting wheel 72. A sliding wheel 74 is movably connected to the bottom left side of the sliding frame 71. The surface of the sliding wheel 74 contacts the inner wall of the ring rail 1.

[0018] Furthermore, the sliding mechanism restricts the sliding direction of the weld flaw detector body 6, preventing it from shifting or falling off during movement and enhancing the stability of the equipment operation. The contact between the sliding wheel 74 and the inner wall of the ring rail 1 reduces the friction during sliding, making the movement of the flaw detector smoother and easier, allowing operators to flexibly control the detection process and improving the ease of operation.

[0019] Please see Figure 1-4 A handle 8 is fixedly connected to the right side of the sliding frame 71, and the handle 8 is located at the bottom of the weld flaw detector body 6.

[0020] Furthermore, the handle 8 provides a convenient grip for operators, making it easy to manually push the weld flaw detector body 6 along the ring rail 1, making the flaw detection operation easier to control and reducing the difficulty of operation; the handle 8 is located at the bottom of the flaw detector body, which conforms to ergonomic design, reduces operator hand fatigue, and improves user comfort.

[0021] Please see Figure 1-4 A reinforcing block 9 is fixedly connected to the right side of the sliding frame 71, and the inner wall of the reinforcing block 9 is fixedly connected to the surface of the handle 8.

[0022] Furthermore, by setting the reinforcing block 9, the structural strength of the connection between the handle 8 and the slide frame 71 can be enhanced, preventing the handle 8 from loosening or breaking due to stress during long-term use, thus extending the service life of the equipment and ensuring safety and reliability during operation.

[0023] Please see Figure 1-4 A rubber sleeve 10 is fitted on the right side of the handle 8 surface, and the rubber sleeve 10 is located at the bottom of the pressure pipe body 4.

[0024] Furthermore, the rubber sleeve 10 increases the friction between the hand and the handle 8, preventing slippage during operation and improving operational stability. At the same time, the rubber material has good elasticity and softness, which can cushion hand pressure, further improving grip comfort and reducing hand discomfort caused by prolonged operation.

[0025] Please see Figure 1-4 The bottom of the sliding frame 71 is fixedly connected with a triangular rib 11, which is located on the right side of the limit rail 73.

[0026] Furthermore, the triangular ribs 11 enhance the overall structural strength and deformation resistance of the sliding frame 71, preventing it from bending or being damaged under stress. In particular, they can cope with the lateral force generated by the contact between the limit wheel 72 and the limit rail 73, extending the service life of the sliding mechanism and ensuring the long-term stable operation of the equipment.

[0027] The specific implementation process of this utility model is as follows: When in use, first pull the round rod 2, the round rod 2 stretches the spring 5, the round rod 2 drives the clamping block 3 to disperse, then the ring rail 1 is sleeved on the surface of the pressure pipe body 4, then the ring rail 1 is moved to a suitable position, and then the round rod 2 is released, and the ring rail 1 is fixed on the surface of the pressure pipe body 4 by the elastic force of the spring 5. Start the weld flaw detector body 6, the user holds the handle 8 and pushes the slide frame 71 to move. The slide frame 71, together with the limit wheel 72 and the slide wheel 74, rotates around the pressure pipe body 4 on the surface of the ring rail 1. During this time, the weld flaw detector body 6 can smoothly rotate 360 ​​degrees around the pressure pipe body 4 for inspection.
