Description

Technical Field

[0001] This utility model belongs to the field of X-ray flaw detector technology, specifically relating to a portable X-ray flaw detector. Background Technology

[0002] X-ray flaw detectors utilize the properties of X-rays to penetrate and attenuate within materials to detect defects in metallic and non-metallic objects. They are generally used to detect defects such as welds and porosity. Because X-ray flaw detectors are relatively heavy, and existing models lack convenient mobility mechanisms, moving them over long distances requires significant physical exertion from the operators.

[0003] Chinese Patent CN213209960U discloses a portable high-frequency X-ray flaw detector, comprising a flaw detector body. A first movable handle is located on one side of the flaw detector body, and a second movable handle is located on the other side. Four connecting structures are symmetrically mounted on the second movable handle. Each of the four connecting structures has a fixing device inside, and each of the four connecting structures has a mounting hole. The four connecting structures are mounted on the second movable handle through the mounting holes. The outer walls of each of the four connecting structures are... Each of the four supporting legs has a swivel caster. Each of the four connecting structures has a connecting through hole on the inner wall of its mounting hole. Each of the four connecting structures also has a spring storage cavity on the inner wall of its four connecting through holes. Four fixing devices are respectively installed within the four connecting through holes. Each fixing device has a limit stop plate on its outer wall within the spring storage cavity. Each fixing device has a limit spring at the outer end of the limit stop plate. Each of the four fixing devices has a connecting pull block at its outer end.

[0004] Regarding the aforementioned technologies, the inventors have discovered at least the following problems: when moving the X-ray flaw detector, it is necessary to first rotate and adjust the four universal pulleys separately before the four universal pulleys can be brought into contact with the ground in order to push the X-ray flaw detector to start moving. The operation is relatively cumbersome and the convenience needs to be improved. Utility Model Content

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

[0013] This easily movable X-ray flaw detector, through the setting of the moving mechanism, when the X-ray flaw detector needs to be moved, only the drive assembly is used to drive the four screws to rotate simultaneously, so that the four screws drive the four connecting pipes to slide vertically along the screws. Through the connecting pipes, the sliding ring drives the sliding ring to slide down along the main body of the X-ray flaw detector, so that the sliding ring drives the universal wheel to contact the ground, and the X-ray flaw detector can be pushed to start moving. The operation is convenient and improves the convenience of moving the X-ray flaw detector.

[0014] This portable X-ray flaw detector, through its drive assembly, can be operated simply by rotating a handwheel.

[0019] The present invention will be further described below with reference to the embodiments.

[0020] The following embodiments are used to illustrate the present invention, but should not be used to limit the scope of protection of the present invention. The conditions in the embodiments can be further adjusted according to specific conditions, and simple improvements to the method of the present invention under the premise of the concept of the present invention are all within the scope of protection claimed by the present invention.

[0021] Please see Figure 1-3 This utility model provides a portable X-ray flaw detector, including an X-ray flaw detector body 1 and a moving mechanism 2. The moving mechanism 2 includes a fixed ring 21 fixedly installed on the X-ray flaw detector body 1 and a sliding ring 22 slidably sleeved on the X-ray flaw detector body 1. Four annularly distributed casters 23 are rotatably mounted on the bottom of the sliding ring 22. The casters 23 are made of nylon. Four annularly distributed screws 24 are rotatably mounted inside the fixed ring 21. The screws 24 are arranged along the axial direction of the X-ray flaw detector body 1. Four annularly distributed connecting pipes 25 are fixedly connected to the top of the sliding ring 22. The four connecting pipes 25 are... The fixed ring 21 is fitted onto the lower end of the four screws 24 and threadedly connected to them. A drive assembly 26 is provided on the fixed ring 21 to drive the four screws 24 to rotate simultaneously. With the setting of the moving mechanism 2, when the X-ray flaw detector needs to be moved, the drive assembly 26 is used to drive the four screws 24 to rotate simultaneously, so that the four screws 24 drive the four connecting pipes 25 to slide vertically along the screws 24. The connecting pipes 25 drive the sliding ring 22 to slide down along the main body 1 of the X-ray flaw detector, so that the sliding ring 22 drives the universal wheel 23 to contact the ground, and the X-ray flaw detector can be pushed to start moving. The operation is convenient and improves the convenience of moving the X-ray flaw detector.

[0022] Specifically, the drive assembly 26 includes a gear 261 fixedly mounted on a screw 24 and a gear ring 262 rotatably mounted in a fixed ring 21. The gear 261 and the gear ring 262 are meshed together. A handwheel 263 is fixedly connected to the upper end of one of the screws 24. A limit ring 264 is provided on the inner wall of the fixed ring 21. The gear ring 262 is slidably connected to the limit ring 264. With the drive assembly 26, during operation, only the handwheel 263 needs to be rotated to make the handwheel 263 drive one of the screws 24 and the gear 261 to rotate. The gear 261 drives the gear ring 262 to rotate. The gear ring 262 drives all the gears 261 to rotate, and all the gears 261 drive all the screws 24 to rotate simultaneously.

[0023] Furthermore, four annularly distributed guide rods 27 are fixedly connected to the bottom of the fixed ring 21. The sliding ring 22 is slidably connected to the guide rods 27. The guide rods 27 can guide and limit the sliding ring 22, thereby improving the stability of the sliding ring 22.

[0024] The working principle and usage process of this utility model are as follows: First, when it is necessary to move the X-ray flaw detector, simply rotate the handwheel 263. The handwheel 263 drives one of the screws 24 and the gear 261 to rotate, which in turn drives the gear ring 262 to rotate. The gear ring 262 drives all the gears 261 to rotate, which in turn drives all the screws 24 to rotate simultaneously. This causes the four screws 24 to drive the four connecting pipes 25 to slide vertically along the screws 24. The connecting pipes 25 drive the sliding ring 22 to slide down along the main body 1 of the X-ray flaw detector, which in turn drives the universal wheel 23 to contact the ground. This allows the X-ray flaw detector to start moving. The operation is convenient and improves the ease of moving the X-ray flaw detector.

[0025] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
