Description

Technical Field

[0001] This invention relates to the field of lifting frame technology, specifically to lifting frames for X-ray inspection equipment. Background Technology

[0002] The welding quality of ship welds plays a crucial role in the safety of ship navigation. Therefore, after the welding of hull plates, structures, and other welds is completed, methods such as surface visual inspection, cabin pressure tightness test, and non-destructive testing of welds are used to ensure the welding quality. Non-destructive testing methods include X-ray inspection, ultrasonic testing, magnetic particle testing, and penetrant testing.

[0003] X-ray inspection involves taking X-ray images of the target weld, creating an image on a film, and then evaluating the image to determine the internal quality of the weld. Factors such as the clarity and black-and-white quality of the film image directly affect the judgment. This requires precise control over the distance between the X-ray machine and the film, the voltage used in the film-taking equipment, and the shooting time when taking the film on-site. The distance between the X-ray machine and the film is called the focal length of the equipment, which is generally between 600mm and 700mm. When taking film on-site, to ensure sufficient focal length, wooden blocks or iron blocks are often used as pads to adjust the focal length. Adjusting the focal length is cumbersome, often resulting in a long shooting time and low work efficiency. Summary of the Invention

[0004] The purpose of this invention is to solve or at least alleviate the problems existing in the prior art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an X-ray inspection equipment lifting frame, comprising a base, two symmetrically arranged lifting components mounted on the top outer wall of the base, and the same mounting frame mounted on the top of the two lifting components, the same fixing frame fixedly connected to the four inner walls of the mounting frame, and a rotating disk rotatably connected to the top outer wall of the fixing frame, two symmetrically arranged contact mechanisms mounted on the outer wall of the rotating disk, the same drive shaft rotatably mounted between the two lifting components, a handle fixedly connected to one outer wall of the base, and four rollers rotatably mounted on the bottom outer wall of the base.

[0006] By adopting the above structure, the lifting assembly can be easily installed on the base. The height of the rotating disk can be adjusted by the mounting frame. The rotating disk can be easily installed on the X-ray machine through two contact mechanisms. When the rotating disk rotates, it can easily drive the X-ray machine to adjust its orientation. The lifting frame can be easily moved to the designated position by means of the handle and rollers.

[0007] Optionally, a worm gear is rotatably connected to the bottom outer wall of the fixed frame, and one end of the drive shaft of the worm gear is fixedly connected to the rotating disk. A worm is rotatably connected to the bottom outer wall of the fixed frame, and the worm and the worm gear mesh with each other. A handwheel is fixedly connected to one end of the drive shaft of the worm.

[0008] By adopting the above structure, the handwheel is rotated to drive the worm gear to rotate, and the worm gear rotates to drive the worm wheel to rotate, which in turn facilitates the rotation of the rotating disk, thereby facilitating the orientation adjustment of the X-ray machine on the two contact mechanisms.

[0009] Optionally, a battery slot is provided on the top outer wall of the base, and a lithium battery is snapped into the inner wall of the battery slot. A charging connector is embedded in one side outer wall of the base and is electrically connected to the lithium battery.

[0010] By adopting the above structure, the lithium battery can be easily charged via the charging connector, and the lithium battery can be conveniently used to power the electrical equipment in the lifting frame.

[0011] Optionally, the top outer wall of the mounting frame has two symmetrically arranged rectangular slots, and the inner walls of the two rectangular slots are rotatably connected to support wheels, and the two support wheels are in contact with the rotating disk.

[0012] By adopting the above structure, the rectangular groove on the mounting frame facilitates the installation of the support wheels, and the support wheels facilitate the support of the rotating disk, thereby improving the stability of the rotating disk.

[0013] Optionally, the contact mechanism includes a fixed seat fixedly connected to the rotating disk, and a connecting groove is provided on the top outer wall of the fixed seat. A connecting seat is inserted into the inner wall of the connecting groove, and a contact seat is fixedly connected to the top outer wall of the connecting seat. An arc-shaped groove is provided on one side outer wall of the contact seat.

[0014] By adopting the above structure, the rotating disk facilitates the installation of the fixed base, the connecting base facilitates the fixing of the contact base onto the fixed base, and the arc-shaped groove facilitates the placement of the X-ray machine.

[0015] Optionally, the inner walls of both sides of the connecting groove are provided with openings, and the inner walls of both openings are slidably connected with U-shaped limiting brackets. The outer walls of both sides of the connecting seat are provided with limiting grooves, and the limiting brackets are inserted into the inner walls of the limiting grooves. The inner walls of both sides of the fixed seat are fixedly connected with fixing rods, and the outer walls of both fixing rods are sleeved with springs. The two limiting brackets are slidably connected to the outer walls of the two fixing rods respectively. The inner walls of both sides of the fixed seat are fixedly connected with limiting rods, and the limiting brackets are slidably connected to the outer walls of the two limiting rods respectively. The inner wall of the fixed seat is rotatably connected with a driving disk, and the outer wall of the driving disk is eccentrically rotatably connected with two connecting rods. One end of the two connecting rods is rotatably connected to the two limiting brackets respectively. One outer wall of the fixed seat is rotatably connected with a rotating column, and the drive shaft of the rotating column is connected to the driving disk.

[0016] By adopting the above structure, when it is necessary to disassemble the contact seat, rotating the rotating column drives the drive plate to rotate clockwise, and the connecting rod pushes the two limit frames to move apart. When the limit frames move apart, the spring is compressed. When the two limit frames move away from the limit groove on the connecting seat, the contact seat and the connecting seat can be disassembled together.

[0017] Optionally, the lifting assembly includes a lifting box fixedly connected to the base, and the top outer wall of the lifting box has two circular openings. The inner walls of the two circular openings are slidably connected to support columns, and the two support columns are fixedly connected to the mounting frame. The bottom outer walls of the two support columns are fixedly connected to the same sliding seat. The inner wall of the lifting box is fixedly connected to two symmetrically arranged sliding rods, and the sliding seat is slidably connected to the outer walls of the two sliding rods.

[0018] By adopting the above structure, the sliding block facilitates the sliding installation of the sliding seat. When the sliding seat slides, it drives the support column to move. When the support column moves, it drives the mounting frame to adjust its height, thereby facilitating the adjustment of the X-ray machine's height.

[0019] Optionally, two support frames are fixedly connected to the bottom inner wall of the lifting box, and the two support frames and the inner walls on both sides of the lifting box are rotatably connected by the same double-acting screw. A worm gear II is fixedly connected to the midpoint of the double-acting screw. The inner walls on both sides of the lifting box are fixedly connected to the same worm II, and the worm II and the worm wheel II mesh with each other. One end of the worm II is fixedly connected to the drive shaft. A reduction motor is fixedly connected to one side of the top outer wall of the base, and the output shaft of the reduction motor is fixedly connected to the worm II.

[0020] By adopting the above structure, the worm gear 2 in the two lifting components is driven to rotate by the geared motor and the drive shaft. When the worm gear 2 rotates, it drives the worm wheel 2 to rotate, which in turn drives the bidirectional lead screw to rotate.

[0021] Optionally, the outer wall of the bidirectional lead screw is screwed with two symmetrically arranged threaded sleeves, and the outer wall of each of the two threaded sleeves is rotatably connected with a support rod, and one end of each of the two support rods is rotatably connected to a sliding seat.

[0022] By adopting the above structure, when the bidirectional lead screw rotates and drives the two threaded sleeves to move towards each other, it works with the support rod to push the sliding seat upward. When the sliding seat moves upward, it directly lifts the mounting frame through the support column, and conversely, it drives the mounting frame to descend, thereby realizing the adjustment of the height of the X-ray machine.

[0023] Optionally, the bottom inner wall of the lifting box is slidably connected to two symmetrically arranged drive blocks, and both drive blocks are screwed onto the outer wall of two bidirectional lead screws. Inclined grooves are provided on the outer sides of both drive blocks. The bottom outer wall of the sliding seat is fixedly connected to two symmetrically arranged connecting frames, and rotating wheels are rotatably connected to the outer wall of the opposite side of the two connecting frames. The rotating wheels are arranged on the inner wall of the groove.

[0024] By adopting the above structure, the two drive blocks on the bidirectional screw move towards each other. At this time, the rotating wheel, with the cooperation of the groove, pushes the sliding seat upward through the connecting frame. When the sliding seat moves upward, it directly lifts the mounting frame through the support column, thereby realizing the adjustment of the height of the X-ray machine.

[0025] Compared with the prior art, the beneficial effects of the present invention are: (1) The present invention provides two contact mechanisms on the rotating disk to facilitate the fixed support of the X-ray machine. At the same time, the rotating disk can be rotated and adjusted, which facilitates the adjustment of the direction of the X-ray machine. In addition, the lifting components on the base facilitate the adjustment of the height of the X-ray machine. Through the cooperation between the lifting components, the mounting frame and the rotating disk, the adjustability of the X-ray machine is improved, thereby improving the detection efficiency of the X-ray machine. (2) By setting a worm gear at the bottom of the mounting frame, the handwheel drives the worm gear to rotate, which directly drives the rotating disk to rotate. When the rotating disk rotates, it is convenient to adjust the angle of the X-ray machine through the contact mechanism. At the same time, the worm gear and worm wheel have high precision when driven together, and the worm gear and worm wheel have a self-locking function, thereby improving the stability of the X-ray machine. (3) By setting a bidirectional lead screw in the lifting assembly, the bidirectional lead screw can directly drive the support column to slide when it rotates. During the sliding and lifting process of the support column, the height of the X-ray machine can be easily adjusted by rotating the disk, thus facilitating the rapid adjustment of the X-ray machine when inspecting ship welds.

[0032] For details, please refer to Figure 7The contact mechanism 8 includes a fixed base 31 fixedly connected to the rotating disk 7. A connecting groove is formed on the top outer wall of the fixed base 31, and a connecting base 32 is inserted into the inner wall of the connecting groove.

One side of the outer wall of the fixed seat 31 is rotatably connected to the rotating column, and the drive shaft of the rotating column is connected to the drive disk 35. When it is necessary to disassemble the contact seat 33, the rotating column is rotated to drive the drive disk 35 to rotate clockwise, and the two limit frames 34 are pushed apart by the connecting rods 36. When the limit frames 34 are moved apart, the spring 38 is compressed. When the two limit frames 34 are away from the limit groove on the connecting seat 32, the contact seat 33 and the connecting seat 32 can be disassembled.

[0033] For details, please refer to Figure 6-8The lifting assembly 3 includes a lifting box 15 fixedly connected to the base 1. Two circular openings are formed on the top outer wall of the lifting box 15. Support columns 17 are slidably connected to the inner walls of both openings, and the two support columns 17 are fixedly connected to the mounting frame 6. A single sliding seat 18 is fixedly connected to the bottom outer wall of the two support columns 17. Two symmetrically arranged sliding rods 19 are fixedly connected to the inner wall of the lifting box 15. The sliding seat 18 is slidably connected to the outer walls of the two sliding rods 19. The sliding rods 19 facilitate the sliding installation of the sliding seat 18. When the sliding seat 18 slides, it drives the support columns 17 to move. When the support columns 17 move, they drive the mounting frame 6 to adjust its height, thus facilitating the adjustment of the X-ray machine's height. Two support frames 20 are fixedly connected to the bottom inner wall of the lifting box 15. A single double-acting screw 23 is rotatably connected between the two support frames 20 and the inner walls of both sides of the lifting box 15. A worm gear 21 is fixedly connected to the midpoint of the double-acting screw 23. The base 1 is fixedly connected to the same worm gear 22, and the worm gear 22 and the worm wheel 21 mesh with each other. One end of the worm gear 22 is fixedly connected to the drive shaft 14. A geared motor 16 is fixedly connected to one side of the top outer wall of the base 1, and the output shaft of the geared motor 16 is fixedly connected to the worm gear 22. The geared motor 16, in conjunction with the drive shaft 14, drives the worm gear 22 in the two lifting components 3 to rotate. When the worm gear 22 rotates, it drives the worm wheel 21 to rotate, which in turn drives the bidirectional lead screw 23 to rotate. The outer wall of the bidirectional lead screw 23 is screwed with two symmetrically arranged threaded sleeves 24, and the outer wall of each threaded sleeve 24 is rotatably connected to a support rod 25. One end of each support rod 25 is rotatably connected to the sliding seat 18. When the bidirectional lead screw 23 rotates and drives the two threaded sleeves 24 to move towards each other, it works with the support rods 25 to push the sliding seat 18 upward. When the sliding seat 18 moves upward, it directly lifts the mounting frame 6 through the support column 17. Conversely, it drives the mounting frame 6 to descend, thereby realizing the adjustment of the height of the X-ray machine.

[0034] Based on Embodiment 1, this embodiment describes the specific structure of the lifting assembly 3 in the lifting frame of the X-ray inspection equipment, such as... Figure 9 As shown, two symmetrically arranged drive blocks 26 are slidably connected to the inner wall of the bottom of the lifting box 15, and both drive blocks 26 are screwed onto the outer wall of two bidirectional screw rods 23. Inclined grooves 27 are provided on the outer sides of both sides of the two drive blocks 26. Two symmetrically arranged connecting frames 28 are fixedly connected to the outer wall of the bottom of the sliding seat 18, and rotating wheels 29 are rotatably connected to the outer wall of the opposite side of the two connecting frames 28. The rotating wheels 29 are set on the inner wall of the grooves 27. When the two drive blocks 26 on the bidirectional screw rods 23 move towards each other, the rotating wheels 29, with the cooperation of the grooves 27, push the sliding seat 18 upward through the connecting frames 28. When the sliding seat 18 moves upward, it directly lifts the mounting frame 6 through the support column 17, thereby realizing the adjustment of the height of the X-ray machine.

[0035] Working principle: In use, first place the X-ray machine for inspecting ship welds on the contact seat 33. Push the base 1 to the designated position using the handle 5. When the height of the X-ray machine needs to be adjusted, start the geared motor 16 to drive the lifting assembly 3, adjusting the height of the mounting frame 6. The change in the height of the mounting frame 6 causes the height of the X-ray machine to change. The handwheel 12 drives the worm gear 11 to rotate. When the worm gear 11 rotates, it drives the worm wheel 10 to rotate. The worm wheel 10 rotates, driving the rotating disk 7 to rotate. When the rotating disk 7 rotates, the X-ray machine's orientation is adjusted through the contact mechanism 8. When the geared motor 16 starts, it drives the two worm gears 22 to rotate synchronously through the transmission shaft 14. When the worm gears 22 rotate, they drive the double-acting screw 23 to rotate through the worm wheel 21. When the double-acting screw 23 rotates... When the two threaded sleeves 24 move towards each other, the supporting rod 25 pushes the sliding seat 18 upward. When the sliding seat 18 moves upward, it directly lifts the mounting frame 6 through the supporting column 17, or it moves towards each other through the two driving blocks 26 on the double-acting screw 23. At this time, the rotating wheel 29, with the cooperation of the groove 27, pushes the sliding seat 18 upward through the connecting frame 28. When the sliding seat 18 moves upward, it directly lifts the mounting frame 6 through the supporting column 17. When the contact seat 33 needs to be replaced, the rotating column drives the driving disk 35 to rotate clockwise, and pushes the two limiting frames 34 to move away from each other through the connecting rod 36. When the limiting frames 34 move away from each other, they compress the spring 38. When the two limiting frames 34 are far away from the limiting groove on the connecting seat 32, the contact seat 33 and the connecting seat 32 can be disassembled.
