Description

Technical Field

[0001] This utility model relates to rotating ultrasonic testing technology and its equipment, specifically, an in-tube support and centering device. Background Technology

[0002] When using in-tube rotating ultrasonic testing, the rotating head, focusing probe, reflector, and other components must be placed inside the tube to be tested, in the center of the tube, and maintain a relatively stable position during the testing process.

[0003] Therefore, it is essential to provide a convenient, mobile, and reliable in-pipe alignment device.

[0004] Therefore, it is necessary to provide an in-tube support centering device to achieve the above objectives. Utility Model Content

[0005] The purpose of this invention is to provide an internal support and centering device.

[0006] The technical solution is as follows:

[0007] A pipe-support centering device includes a hollow pipe. The hollow part of the hollow pipe is used as a corresponding area for passing through lines and water. Both ends of the hollow pipe are provided with a central support member. When the central support member is inside the pipe fitting, it supports the inner wall of the pipe fitting and serves as a centering support structure to position the hollow pipe at the center of the pipe fitting.

[0008] The central support component includes several evenly distributed support rods, with rollers at the ends of the support rods. When the hollow tube moves, the support rods and end rollers simultaneously support the same circular tangent on the inner wall of the tube, forming an integrated structure that ensures the centering and support of the hollow tube at the center of the tube to be tested.

[0009] Furthermore, there are five support rods, and the ends are set with roller fixing pins.

[0010] Furthermore, the support rod includes a fixed end, which is correspondingly mounted on the bracket ring and is locked to the bracket ring by a slanted pressure sleeve and a fixed ring.

[0011] Furthermore, the support ring is fixed to the hollow tube by the set screws on the support ring part.

[0012] Furthermore, the middle support also includes a clamping elastic element, with the inclined pressure sleeve and the pre-compression fixing ring respectively held at both ends of the clamping elastic element.

[0013] Furthermore, the clamping elastic element can be a compression spring, a tension spring, a rubber component, or a polyurethane elastomer.

[0014] Furthermore, the pre-compression fixing ring is fixed to the hollow tube by the pre-compression fixing ring set screw.

[0015] Compared with the prior art, the advantages of this utility model are: compact and simple structure, easy assembly; stable and reliable centering effect; adjustable support size to meet the needs of a certain size range and reduce the specifications of centering devices; rolling contact to reduce wear and extend service life; adjustable clamping elastic element to provide suitable support force.

[0020] Example:

[0021] Please see Figure 1-4 This embodiment demonstrates an internal support centering device, including a hollow tube 1. The hollow part of the hollow tube 1 is used for the corresponding areas of the line and water passage. Both ends of the hollow tube 1 are provided with a central support member. When the central support member is inside the tube, it supports the inner wall of the tube and serves as a centering support structure to position the hollow tube at the center of the tube.

[0022] The central support includes several evenly distributed support rods 6, with rollers 7 at the ends of the support rods 6. When the hollow tube 1 moves, the support rods 6 and the end rollers 7 simultaneously support the same circular tangent on the inner wall of the tube, forming an integrated structure that ensures the centering and support of the hollow tube 1 in the center of the tube to be tested.

[0023] in:

[0024] There are five support rods 6, and the rollers 7 are set at the ends by roller fixing pins D.

[0025] The support rod 6 includes a fixed end, which is correspondingly mounted on the bracket ring 8, and is locked to the bracket ring 8 by the inclined pressure sleeve 4 and the fixed ring 5.

[0026] The support ring 8 is fixed to the hollow tube 1 by the set screw C of the support ring part.

[0027] After the end of the inclined pressure sleeve 4 and the upper part of the bracket ring 8 are aligned, the fixed ring 5 is set and fixed by the fixing pin B.

[0028] The middle support also includes a clamping elastic element 3, with the clamping elastic element 3 supporting the inclined pressure sleeve 4 and the pre-compression fixing ring 2 at both ends.

[0029] The compression elastic element 3 is a compression spring, a tension spring, a rubber component, or a polyurethane elastomer.

[0030] The pre-compression fixing ring 2 is fixed to the hollow tube 1 by the pre-compression fixing ring set screw A.

[0031] Hollow tube 1 has external threads at both ends for easy installation: one end is threaded to connect to the water supply pipe connector, and the probe cable passes through the inside of the tube; the other end is threaded to connect to the rotating head and probe.

[0032] The support ring 8 is installed on the hollow tube and fixed to the outside of the tube with a set screw C. The inclined end of the support rod 6 is inserted into the groove of the support ring 8 and nested in the fixed ring 5. The fixed ring 5 and the support ring 8 are riveted together with a fixing pin B, and the inclined end of the support rod 6 is thus locked in the groove of the support ring 8.

[0033] The inclined pressure sleeve 4, the compression spring 3, and the pre-compression fixing ring 2 are sequentially fitted onto the hollow rod 6 and pressed against the support ring 8. The inner inclined surface of the inclined pressure sleeve 4 presses against the inclined end of the support rod 6. The set screw A fixes the fixing ring 8 to the hollow tube.

[0034] The inclined pressure sleeve 4 can move axially on the hollow tube. Under the preload of the compression spring 3, it presses against the side of the support ring 8, pressing the inclined end of the support rod 6. Under the action of leverage, the roller end of the support rod 6 opens outward and abuts against the inner wall of the pipe to be tested, completing the positioning. During the movement, as the pipe diameter changes slightly, the opening distance of the support rod 6 also changes, and the inclined pressure sleeve 4 moves back and forth accordingly. The compression spring 3 will then extend and retract, thus adapting to the change in pipe diameter.

[0035] Compared with the prior art, the advantages of this utility model are: compact and simple structure, easy assembly; stable and reliable centering effect; adjustable support size to meet the needs of a certain size range and reduce the specifications of centering devices; rolling contact to reduce wear and extend service life; adjustable clamping elastic element to provide suitable support force.

[0036] For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
