Description

Technical Field

[0001] The utility model relates to the field of disassembly and assembly tools, in particular to a disassembly and assembly tool for an accelerator bellows. Background Art

[0002] At present, after the ELEKTA accelerator has been in use for a period of time, vacuum failure will occur and the bellows seal needs to be replaced to ensure that the vacuum of the entire accelerator tube meets the clinical use requirements. The installation space of the bellows is small and the torque of all tightening bolts must be the same during installation.

[0003] The currently adopted method for disassembling and assembling the bellows is to remove the fixing bolts of the bellows by using a plum-shaped combination wrench after opening the accelerator tube cavity. However, since there are 6 fixing bolts of the bellows in the accelerator evenly distributed along the outside of the bellows, and the accelerator as a whole cannot be moved, in the process of removing the fixing bolts with a plum-shaped combination wrench, the angle of the fixing bolts on the inside is often inconvenient, and the space left at the installation position of the bellows is a curved channel, which is not enough to put down the wrench, making it difficult to disassemble, affecting the installation progress. The same problem also exists during installation. Utility Model Content

[0004] The utility model aims to provide a disassembly and assembly tool for an accelerator bellows in order to overcome the defect of the prior art that the existing double-purpose spanner often encounters the problem of insufficient space to put down the spanner in a curved channel.

[0005] The purpose of the utility model can be achieved through the following technical solutions:

[0006] A plum blossom wrench comprises a wrench body and a plum blossom head, wherein the plum blossom head is obliquely connected to the wrench body, the inclination angle between the plum blossom head and the wrench body is within the range of 125 degrees to 155 degrees, and the plum blossom head is provided with a plum blossom-shaped opening.

[0007] Furthermore, the end faces of the connection between the plum blossom head and the wrench body are all cut surfaces, the plum blossom head is welded and connected to the wrench body, and the connection between the plum blossom head and the wrench body is filled with cast iron.

[0008] Furthermore, an open head is provided at one end of the wrench body away from the plum blossom head.

[0009] The utility model also provides a disassembly and assembly tool for an accelerator bellows, which is used for disassembling and assembling the fixing bolts of the accelerator bellows. The disassembly and assembly tool comprises a plum blossom wrench, which comprises a wrench body and a plum blossom head. The plum blossom head is obliquely connected to the wrench body, and the oblique angle between the plum blossom head and the wrench body is within the range of 125 degrees to 155 degrees. The plum blossom head is provided with a plum blossom-shaped opening, which is matched with the fixing bolts.

[0010] The length of the plum blossom head is within the range of 0.15-0.3 times the total length of the plum blossom wrench.

[0011] Furthermore, the end faces of the connection between the plum blossom head and the wrench body are all cut surfaces, the plum blossom head is welded and connected to the wrench body, and the connection between the plum blossom head and the wrench body is filled with cast iron.

[0012] Furthermore, the plum blossom-shaped opening matches the shape and size of the fixing bolt.

[0013] Furthermore, an open head is provided at one end of the wrench body away from the plum blossom head.

[0014] Furthermore, the overall length of the plum blossom wrench is 120 mm, the length of the plum blossom head is 25 mm, and the inclined angle between the plum blossom head and the wrench body is 135 degrees.

[0015] Furthermore, the material of the box wrench is stainless steel, carbon steel or iron.

[0016] Furthermore, the accelerator bellows is a bellows of an ELEKTA accelerator, and the fixing bolts are distributed around the end surface of the bellows.

[0017] Compared with the prior art, the utility model has the following advantages:

[0018] (1) This solution cuts and trims the plum head portion of the plum wrench, then welds the cut plum head to the wrench body at an angle within a range of 125 degrees to 155 degrees, and fills the weld with cast iron. The plum wrench with a bent plum head can easily fit the plum head into the bent space, thereby improving installation efficiency.

[0019] Moreover, the scheme only requires cutting the plum blossom head of the existing plum blossom wrench and then welding it through cast iron, which is convenient to manufacture, low in cost and easy to use.

[0020] (2) The utility model uses the plum blossom wrench with a bent plum blossom head to easily allow the plum blossom head to enter the space near the inner side of the bellows, thereby improving installation efficiency, shortening the time the vacuum chamber is exposed to the atmosphere, reducing the vacuum that fails to meet use requirements due to improper installation, and improving the accelerator startup rate.

[0021] (3) Timeliness: The length of a normal 10mm open-end plum blossom wrench is 120mm. The remaining space at the bellows installation location is insufficient to put down the wrench, which affects the installation progress, increases the time the vacuum chamber is exposed to the atmosphere, and affects the subsequent time to establish a vacuum.

[0022] After modifying the wrench, it will be much more convenient to disassemble and assemble the bellows, shortening the time that the accelerator tube cavity is exposed to the atmospheric environment, greatly reducing downtime caused by such failures.

[0023] (4) Ease of use: simple modification, strong practicality, and easy operation. BRIEF DESCRIPTION OF THE DRAWINGS
