Description

Technical Field

[0001] This utility model relates to the field of GIS equipment testing technology, and in particular to an adjustment platform for a non-destructive testing instrument for GIS equipment. Background Technology

[0002] Non-destructive testing (NDT) of GIS equipment is a method of detecting internal defects or potential hazards in gas-insulated metal-enclosed switchgear (GIS) using non-destructive techniques to ensure safe operation. Key technologies include X-ray inspection, ultrasonic testing, and partial discharge detection. X-ray inspection utilizes high-resolution imaging to penetrate equipment and accurately identify internal structural defects, such as contact deformation and damaged insulation components, without requiring disassembly of the equipment. X-ray inspection can detect hazards such as loose parts, burned contact fingers, and cracked insulation rods, preventing large-scale power outages due to malfunctions.

[0003] In X-ray inspection, non-destructive testing equipment, also known as X-ray machines, is mainly used. Because the height of the objects being inspected varies, the height of the X-ray machine needs to be adjusted according to the specific site conditions. Currently, there is no dedicated adjustment equipment for this purpose. Utility Model Content

[0004] To overcome the shortcomings of the prior art, this utility model provides a highly adjustable and convenient adjustment platform for a non-destructive testing instrument for GIS equipment.

[0005] This utility model is achieved through the following technical solution: A non-destructive testing (NDT) adjustment platform for GIS equipment includes a base. The base has a telescopic support rod composed of a first telescopic joint, a second telescopic joint, and a third telescopic joint. The first and second telescopic joints each have elongated holes located on different sides. The first telescopic joint has a U-shaped hole that overlaps with the elongated hole of the second telescopic joint. Hand crank shafts are located at the upper ends of both the first and second telescopic joints, and pull ropes are wound around these shafts. The two hand crank shafts are located at the top of the elongated holes. The free end of the pull rope from the first telescopic joint is fixedly connected to the lower end of the second telescopic joint, and the free end of the pull rope from the second telescopic joint is fixedly connected to the third telescopic joint. A locking device is provided for each hand crank shaft. A X-ray machine placement frame is located at the upper end of the third telescopic joint.

[0006] The locking device is a ratchet structure.

[0007] Two ear plates are fixedly mounted on the top ends of the first and second telescopic joints, respectively. The hand crank shaft is rotatably mounted between the two ear plates. The ratchet of the ratchet structure is coaxially mounted with the hand crank shaft, and the pawl of the ratchet structure is mounted on the ear plates.

[0008] The X-ray machine placement frame includes a cuboid frame with a groove at the top.

[0009] An inclined support rod is provided between the cuboid frame and the third expansion joint.

[0010] The groove is equipped with a fastening strap.

[0011] The base is equipped with rollers with foot brakes.

[0012] The beneficial effects of this utility model are: This invention features a hand-cranked wheel shaft, which, through rotation, raises the telescopic joint, thereby increasing the height of the X-ray machine in a convenient and quick manner.

[0013] This invention also features a ratchet structure, allowing each telescopic section to stop at any height, facilitating the adjustment of the X-ray machine's height according to actual site conditions. Attached Figure Description

Detailed Implementation

[0016] The attached figure shows a specific embodiment of this utility model.

[0017] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0018] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0019] like Figures 1 to 5 As shown, the adjustment platform of this type of GIS equipment non-destructive testing instrument includes a base 1, on which rollers 2 are mounted, and the rollers 2 are preferably equipped with foot brakes.

[0020] A first telescopic section 3 is fixedly installed on the base 1. The first telescopic section 3 is cylindrical, with an elongated hole 6 on one side and a U-shaped hole 7 on the other side opposite to the elongated hole 6. A second telescopic section 4 is inserted into the first telescopic section 3. The second telescopic section 4 also has an elongated hole 6, which coincides with the U-shaped hole 7 of the first telescopic section 3. The second telescopic section 4 is also cylindrical, and a third telescopic section 5 is inserted into the second telescopic section 4. The top of the third telescopic section 5 is fixedly installed with a radiation machine placement frame.

[0021] Ideally, the first expansion joint 3, the second expansion joint 4, and the third expansion joint 5 should all be square tubes.

[0022] Two parallel ear plates 8 are respectively installed at the top of the elongated holes 6 of the first telescopic joint 3 and the second telescopic joint 4. The two ear plates 8 are parallel to the length direction of the first telescopic joint 3. A hand crank shaft 9 is rotatably installed between the two ear plates 8. A hand crank 10 is installed at one end of the hand crank shaft 9. In addition, a ratchet is coaxially fixedly installed on the hand crank shaft 9. A pawl is installed on the ear plate 8. The ratchet and the pawl form a ratchet structure 16.

[0023] A pull rope 11 is wound around the hand crank shaft 9. The free end of the pull rope 11 of the first telescopic joint 3 is fixed to the lower end of the second telescopic joint 4, and the free end of the pull rope 11 of the second telescopic joint 4 is fixed to the lower end of the third telescopic joint 5.

[0024] The X-ray machine placement frame includes a cuboid frame 12, the upper end face of which is a groove 13. The groove 13 can be fitted with a fastening strap 14 to fix the X-ray machine.

[0025] An inclined support rod 15 is installed between the cuboid frame 12 and the third expansion joint 5, and the inclined support rod 15 supports the cuboid frame 12.

[0026] The usage process is as follows: Place the X-ray machine into the groove 13 and secure it with the fastening strap 14. Move the present invention to the testing site. According to the height of the equipment to be tested, first crank the hand crank 10 on the second telescopic section 4. The pull rope 11 is wound around the hand crank shaft 9. The pull rope 11 drives the third telescopic section 5 to rise. If the required height can be reached, stop cranking. The ratchet structure locks the hand crank shaft 9 on the second telescopic section 4, and the height of the X-ray machine is limited.

[0027] If the X-ray machine still cannot reach the required height by rotating the hand crank shaft 9 on the second telescopic section 4, then the hand crank 10 on the first telescopic section 3 is cranked, and the second telescopic section 4 is raised by pulling the rope 11, thereby raising the third telescopic section 5 and the X-ray machine to reach the required height.
