Description

Technical Field

[0001] The present invention relates to the technical field of gradient coil installation, and specifically relates to a magnetic resonance gradient coil installation tooling Background Art

[0002] At present, due to the large surface area and heavy self-weight of the permanent magnet magnetic resonance gradient coil, it takes two people to carry the gradient coil alone when moving it up or down. When engineers install or disassemble the gradient coil, it is not only very difficult but also poses certain risks. Especially when installing the upper gradient coil, it often requires three or four people, which is inconvenient, laborious and there are certain safety hazards during installation. At the same time, it is not easy to carry and has a large volume; there is no ready-made non-magnetic tool that can be directly used in a strong magnetic field environment, consuming a lot of labor

[0003] In view of the above problems, CN212553603U discloses a gradient coil installation tooling, which uses balls to complete the movement and positioning during the disassembly and assembly of the gradient coil, and controls the lifting of the gradient coil by adding hydraulic oil to the inlet and outlet through a hydraulic jack, so as to complete the disassembly and assembly operation of the gradient coil

[0004] However, existing gradient coil installation toolings of this kind control the lifting of the upper gradient coil support frame and the gradient coil through a hydraulic jack. However, using a hydraulic jack has a high cost and requires preparing accessories for the hydraulic part such as hydraulic oil and pipes, which does not meet the working guidance standard that service engineers need to carry fewer and lighter things; at the same time, factors such as oil leakage are common in the hydraulic system, affecting the smoothness and correctness of movement, making it impossible to ensure a strict transmission ratio for hydraulic transmission, resulting in the inability to effectively control the lifting precision. It is very easy that when the hydraulic jack controls the gradient coil to rise, the coil rises too high and collides and wears when it continues to rise after entering the magnetic cylinder, or falls too low, causing the magnetic cylinder to separate from the coil, thus affecting the overall use of the device Summary of the Invention

[0005] The problem to be solved by the present invention is a magnetic resonance gradient coil installation tooling that can drive the lifting part to move up and down by lifting and gripping the gripping part, and can effectively control the lifting precision, thereby effectively avoiding phenomena such as the coil rising too high or falling too low, ensuring the overall use of the device; and the pneumatic anti-falling locking part can play a dual role in preventing the lifting part from falling back

Spring positioning pins are arranged on the support frames. An upper gradient coil is arranged on the spring positioning pins. The distance between the spring positioning pins is consistent with the distance between the mounting holes opened on the gradient coil.

[0011] Preferably, the lower support part for the gradient coil includes a lower disc base. Foldable support feet are evenly distributed on the lower disc base. Stainless steel bolts are arranged on the support feet, and the lower disc base is fixed on the lower gradient coil through the stainless steel bolts.

The pneumatic anti-falling locking part 4 can play a dual role in preventing the lifting part from falling back. The air in the cavity of the supporting part 12 is discharged by the pneumatic booster unit 40 of the pneumatic anti-falling locking part 4 to generate booster pressure, so that the lifting part rises and initially maintains the rising position without falling down; when the lifting part rises, the anti-falling locking unit 42 of the pneumatic anti-falling locking part 4 is pushed back to the top, and when the lifting part stops rising, the anti-falling locking unit 42 rebounds and presses against the lifting part, thereby playing a role in preventing the lifting part from falling back again.

[0032] The pneumatic anti-falling locking portion 4 has three parts, including a pneumatic pressurizing unit 40. The pneumatic pressurizing unit 40 is provided at the side end of the support outer cylindrical tube 12-1 and is connected to the cavity 12-6.

[0034] To facilitate the understanding of the above technical solution of the present invention, the above technical solution of the present invention will be described in detail through specific usage modes below.

[0035] The specific working process is as follows: When installing the gradient coil 6, first place the lower support part 3 of the gradient coil on the lower gradient coil 7, and tighten the four stainless steel bolts 3-3 on the support feet 3-2 to fix the lower support part 3 of the gradient coil on the lower gradient coil 7. Place the upper gradient coil 6 on the upper support part 2 of the gradient coil, and move it back and forth and left and right to make the spring positioning pin 2-3 pop into the screw hole of the upper gradient coil 5. At this time, the upper and lower gradient coils are concentric, and at the same time, they are also concentric with the magnetic cylinder 7, eliminating the trouble of continuously adjusting the position state of the upper gradient coil 6 during the ascending process to smoothly enter the magnetic cylinder 7. Then, the engineer only needs to slowly press down the ratchet wrench 13-1 of the gripping part 13 to drive the gear 13-3 to rotate. The gear 13-3 drives the rack 11-3 of the lifting part 11 to rise. The lifting inner cylindrical barrel 11-1 will rise together with the rack in the inner cavity 12-6 of the support outer cylindrical barrel 12-1 of the support part 12. Start the pneumatic booster unit 40 of the pneumatic anti-falling locking part 4. The pneumatic booster unit 40 gradually discharges the air in the cavity, so that while the lifting inner cylindrical barrel 11-1 rises, it initially maintains the rising position and does not fall down; while the rack 11-3 rises, it will push the locking tongue 42-3 of the anti-falling locking unit 42 back. The locking tongue 42-3 drives the spring 42-2 and the elastic blocking block 42-1 to squeeze inward. The locking bolt 42-7 abuts against the elastic blocking block 42-1. When the rack 11-3 stops rising, the locking tongue 42-3 rebounds under the action of the spring 42-2 and abuts against the rack 11-3. The rack 11-3 drives the lifting inner cylindrical barrel 11-1 to stop. At this time, the anti-falling locking unit 42 plays a second role in preventing landing. The upper gradient coil is lifted to the specified position and enters the magnetic cylinder 7 through the reciprocating action of the ratchet wrench 13-1;

[0036] When disassembling the upper gradient coil 6, rotate and pull out the locking bolt 42-7 of the anti-falling locking unit 42 from the threaded connection groove 42-6 at the front end of the positioning seat 42-4, so that the anti-falling locking unit 42 loses its function. At this time, because the space between the lifting inner cylindrical barrel 11-1 and the support outer cylindrical barrel 12-1 in the cavity is very small and air cannot enter the cavity, the upper gradient coil 6 remains in its original state. Then, turn off the pneumatic booster unit 40 and start the pneumatic pressure relief unit 41. Through the pneumatic pressure relief unit 41, air enters the cavity 12-6 little by little. The lifting inner cylindrical barrel 11-1 drives the gear 13-3 to descend. The gear 13-3 will push the locking tongue 42-3 of the anti-falling locking unit 42 back. The locking tongue 42-3 drives the spring 42-2 and the elastic blocking block 42-1 to squeeze inward. The elastic blocking block 42-1 enters the cavity 42-5 of the positioning seat 42-4 due to the lack of the supporting force of the 42-7 locking bolt, so that the upper gradient coil 6 and the lifting inner cylindrical barrel 11-1 slowly descend. At the same time, for safety, the shock-absorbing spring 12-4 at the inner end of the support outer cylindrical barrel 12-1 will play a buffering role when the lifting inner cylindrical barrel 11-1 descends to the bottom.
