Description

Technical Field

[0001] The utility model relates to the technical field of vacuum pump trucks, in particular to an adjustable vacuum pump truck. Background Art

[0002] The existing accelerator vacuum system will be separated into an independent vacuum pump truck, which serves as the front pump of the low-energy accelerator vacuum system. After the vacuum is drawn, it can be removed, reducing the volume of the accelerator vacuum system. Moreover, the movement is basically carried out using casters. However, when working, the pump will generate movement vibration. Since the casters have less contact area with the ground, the vacuum pump truck will move when vibration occurs, making it unstable during use. Utility Model Content

[0028] Furthermore, the adjustable device includes a rotating shaft 12, which is fixedly installed at the middle position of the supporting leg 11 near the bottom, and the two ends of the rotating shaft 12 respectively extend outward through the supporting leg 11, and the two extended ends of the rotating shaft 12 are rotatably sleeved with a U-shaped block 24, and the two vertical plates of the U-shaped block 24 are respectively provided with circular grooves 13 at the opposite angles near the top position, and the outer surface of the U-shaped block 24 is respectively provided with a rectangular slide groove 14 and a circular slide groove 15 at the center position corresponding to the two circular grooves 13.

[0029] Furthermore, a cylinder 16 is fixedly installed on the inner walls of the two circular grooves 13, and a spring 17 is provided on the inner walls of the two cylinders 16. One end of the two springs 17 is fixedly installed on the bottom of the circular groove 13, and the other end of the two springs 17 is fixedly installed with a limiting column 18. The two limiting columns 18 are slidably connected to the inner walls of the two cylinders 16.

[0030] Furthermore, both limit posts 18 are rotatably installed with connecting posts 19 at the center position of one end near the two supporting legs 11, and both connecting posts 19 extend to the outer surface of the U-shaped block 24 through the circular slide groove 15 at one end away from the limit posts 18. The outer surface of both connecting posts 19 at one end away from the limit posts 18 is fixedly installed with a limit block 22, a limit disc 21 and a pull ring 20 in sequence from the inside to the outside.

[0031] Furthermore, the outer surfaces of the two connecting columns 19 are slidably connected to the inner wall of the circular slide 15, the outer surfaces of the two limit blocks 22 are adapted to the rectangular slide 14, and the bottom of the U-shaped block 24 is fixedly mounted with a caster 23.

[0032] Furthermore, it is necessary to manually pull the pull ring 20 by hand to rotate it, and the rotation of the pull ring 20 drives the connecting column 19 to rotate, and the rotation of the connecting column 19 drives the limit disc 21 and the limit block 22 to rotate respectively. After the limit block 22 and the rectangular slide 14 are rotated to the corresponding position, the rotation is stopped and the hands are released. Then, it is necessary to manually step on the U-shaped block 24 and grab the frame 1 and pull it into the worker's arms, so that the U-shaped block 24 rotates with the rotating shaft 12 as the axis so that the U-shaped block 24 is perpendicular to the bottom of the supporting leg 11. After the verticality, the spring 17 stretches to drive the limit column 18 to move forward out of the cylinder 16, and the limit column 18 moves forward to drive the connecting column 19 The connecting column 19 moves forward and drives the limiting disc 21, the limiting block 22 and the pull ring 20 to move forward respectively. When the limiting block 22 moves forward, it slides through the rectangular slide groove 14 and enters the cylinder 16. The limiting disc 21 moves forward and stops moving when it fits the outer surface of the U-shaped block 24. The limiting disc 21 stops moving and finally stops the spring 17 from stretching. The connecting column 19 stops moving and stops the limiting column 18. After the limiting column 18 stops moving, it appears on both sides of the supporting leg 11. The two connecting columns 19 lock the bottom of the supporting leg 11 inside the U-shaped block 24, and the frame 1 is manually pushed to move. After moving to the required position, the pull ring 20 needs to be manually pulled by hand to rotate. After the pull ring 20 rotates and finally rotates the limit block 22 and the rectangular slide 14 to the corresponding position and stops rotating, the worker pulls the pull ring 20 outward to move the pull ring 20 away from the rectangular slide 14. The pull ring 20 drives the spring 17 to squeeze the bottom of the inner wall of the circular groove 13, so that the limit column 18 moves to the inside of the cylinder 16. At the same time, the pull ring 20 moves and drives the limit block 22 to move through the rectangular slide 14 to the outer surface of the U-shaped block 24 and then stops moving. The pull ring 20 is manually rotated, and the rotation of the pull ring 20 finally drives the limit block 22 to rotate , release the limit block 22 when it is in a cross shape with the rectangular slide groove 14, and the limit block 22 is fitted with the outer surface of the caster 23 for limiting. The U-shaped block 24 is rotated around the rotating shaft 12 through the artificial frame 1, and the support leg 11 is at a right angle to the U-shaped block 24, so that the bottom of the support leg 11 is in contact with the ground. The adjustable device effectively prevents the caster from having a small contact area with the ground during use, making the vacuum pump truck unstable during use. The gravity can be directly applied to the ground through the contact between the support leg 11 and the ground, which also increases the contact area with the ground during use, thereby increasing the stability of the device when in use.

[0033] Working principle: When in use, the pull ring 20 needs to be pulled by hand to rotate, and the rotation of the pull ring 20 drives the connecting column 19 to rotate, and the rotation of the connecting column 19 drives the limit disc 21 and the limit block 22 to rotate respectively. After the limit block 22 and the rectangular slide 14 are rotated to the corresponding position, the rotation is stopped and the hands are released. Then, the U-shaped block 24 needs to be stepped on manually and the frame 1 is grasped and pulled into the worker's arms, so that the U-shaped block 24 rotates with the rotating shaft 12 as the axis so that the U-shaped block 24 is perpendicular to the bottom of the supporting leg 11. After the verticality, the spring 17 stretches to drive the limit column 18 to move forward out of the cylinder 16, and the limit column 18 moves forward to drive the connecting The column 19 moves forward, and the connecting column 19 moves forward to drive the limit disc 21, the limit block 22 and the pull ring 20 to move forward respectively. When the limit block 22 moves forward, it slides through the rectangular slide groove 14 and enters the cylinder 16. The limit disc 21 moves forward and stops moving when it fits the outer surface of the U-shaped block 24. The limit disc 21 stops moving and finally stops the spring 17 from stretching. The connecting column 19 stops moving and stops the limit column 18. After the limit column 18 stops moving, it appears on both sides of the support leg 11. The two connecting columns 19 lock the bottom of the support leg 11 inside the U-shaped block 24, and the frame 1 is manually pushed to proceed. Move, after moving to the required position, it is necessary to manually pull the pull ring 20 by hand to rotate it. After the pull ring 20 rotates and finally rotates the limit block 22 and the rectangular slide 14 to the corresponding position and stops rotating, the worker pulls the pull ring 20 outward to move the pull ring 20 away from the rectangular slide 14. The pull ring 20 drives the spring 17 to squeeze the bottom of the inner wall of the circular groove 13, so that the limit column 18 moves to the inside of the cylinder 16. At the same time, the pull ring 20 moves to drive the limit block 22 to move through the rectangular slide 14 to the outer surface of the U-shaped block 24 and then stops moving. The pull ring 20 is manually rotated, and the rotation of the pull ring 20 finally drives the limit block 22 to rotate The limit block 22 is moved, and the limit block 22 is rotated to form a cross with the rectangular slide groove 14, so that the limit block 22 is fitted with the outer surface of the caster 23 for limiting. The U-shaped block 24 is rotated around the rotating shaft 12 through the artificial frame 1, and the support leg 11 is at a right angle to the U-shaped block 24, so that the bottom of the support leg 11 is fitted with the ground. The adjustable device effectively prevents the caster from having a small contact area with the ground during use, making the vacuum pump vehicle unstable during use. The gravity can be directly applied to the ground through the contact between the support leg 11 and the ground, which also increases the contact area with the ground during use, thereby increasing the stability of the device when in use.
