[0001] The utility model relates to the technical field of auxiliary mobile devices, and more specifically, to a vertical cavity maintenance mobile device. Background Art

[0002] A vertical vacuum chamber is a vertically installed vacuum device, which is usually used in industrial applications that require processing in a vacuum environment. The design of this vacuum chamber can provide an oxygen-free or low-oxygen environment to prevent material oxidation or carry out specific chemical reactions. Therefore, the vertical vacuum chamber plays an important role in fields such as semiconductor manufacturing, materials science experiments, precision coating, photovoltaic solar energy, and advanced precision medical equipment.

[0003] In a general vertical vacuum chamber production line, since various assembly, debugging, and repair operations need to be carried out on the chamber, aluminum alloy ladders or simple trolleys are often placed everywhere, and the operators carry tools by themselves for installation operations. Since the overall vertical production line requires the substrate or glass to enter and exit vertically, most of the chambers are relatively high, which makes it extremely inconvenient for the operators to install and maintain on the chamber, and there are no safety measures to protect the operators. Therefore, it needs to be improved. Summary of the Utility Model

[0004] In order to overcome the deficiencies of the prior art, the utility model provides a vertical cavity maintenance mobile device, which has the advantage of being convenient for installation.

The front end of the bolt sequentially penetrates through the lower fixed ladder and the movable ladder and extends to the outside of the movable ladder. The outer surface of the bolt is movably sleeved with the inner surfaces of the movable ladder and the lower fixed ladder respectively, and the other end of the bolt is fixedly connected to a connecting block.

[0010] As a preferred technical solution of the present utility model, the number of the connecting blocks is two.

Specific embodiments

[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present utility model.

[0022] As Figures 1 to 5 shown, the present utility model provides a vertical cavity maintenance mobile device, including a movable ladder 1. The lower surface of the movable ladder 1 is fixedly connected with a lower fixed plate 2. The left surface of the movable ladder 1 is movably connected with a lower fixed ladder 3. The top end of the lower fixed ladder 3 is fixedly connected with a mounting rack 4. The left side of the upper surface of the mounting rack 4 is fixedly connected with an upper fixed ladder 5. The top end of the left surface of the upper fixed ladder 5 is fixedly connected with an upper fixed plate 6. The front and rear sides of the right surface of the upper fixed ladder 5 are both fixedly connected with guardrails 7. The lower surfaces of the lower fixed plate 2 and the upper fixed plate 6 are both movably installed with brake casters 8.

[0023] The overall design of the movable ladder 1, the lower fixed ladder 3 and the mounting rack 4 can ensure that the whole movable ladder 1 will not shake during installation by the operator. The design of the brake casters 8 enables the whole movable ladder 1 to stop as it moves, greatly ensuring the safety of the operator during installation operations.

[0024] Among them, the upper surface of the mounting rack 4 is fixedly connected with a standing plate 9 located on the right side of the upper fixed ladder 5, and the outer shape of the standing plate 9 is rectangular.

[0025] The design of the standing board 9 provides space for the operator to stand and place tools, facilitating the installation operation of the cavity.

[0026] On the front and rear sides of the right surface of the movable ladder 1, handrails 10 are fixedly connected. The number of handrails 10 is two, and the positions of the two handrails 10 are symmetric about the front and rear of the movable ladder 1.

[0027] The design of the handrails 10 facilitates the operator to climb upwards.

[0028] On the upper sides of the outer surfaces of the front and rear sides of the movable ladder 1, limit blocks 11 are fixedly connected. The outer surface of the lower fixed ladder 3 is movably connected to the outer surface of the limit blocks 11.

[0029] The whole lower fixed ladder 3 can move up and down under the limitation of the limit blocks 11.

[0030] On the outer surface of the limit block 11, a bolt 12 is movably connected. The front end of the bolt 12 sequentially penetrates through the lower fixed ladder 3 and the movable ladder 1 and extends to the outside of the movable ladder 1. The outer surface of the bolt 12 is movably sleeved with the inner surfaces of the movable ladder 1 and the lower fixed ladder 3 respectively, and the other end of the bolt 12 is fixedly connected to a connecting block 13.

[0031] When the outer surface of the bolt 12 comes into contact with the inner surfaces of both the movable ladder 1 and the lower fixed ladder 3 simultaneously, the moving function of the movable ladder 1 will be locked by the bolt 12, fixing the movable ladder 1 on the outer surface of the lower fixed ladder 3.

[0032] The number of connecting blocks 13 is two. A pull rod 14 is fixedly connected to the inner surface between the two connecting blocks 13. The outer surface of the bolt 12 is movably sleeved with a spring 15. The front end of the spring 15 is fixedly connected to the outer surface of the limit block 11, and the other end of the spring 15 is fixedly connected to the outer surface of the connecting block 13.

[0033] The design of the pull rod 14 facilitates the operator to grasp and pull.

[0034] On the outer surface of the lower fixed ladder 3, a first jack 16 is opened below the bolt 12, and a second jack 17 is opened below the first jack 16 on the outer surface of the lower fixed ladder 3.

[0035] When the bolt 12 aligns with the first jack 16 or the second jack 17, the bolt 12 will be inserted into the first jack 16 or the second jack 17 under the elastic force of the spring 15, thereby realizing the function of adjusting the overall length of the movable ladder 1 and the lower fixed ladder 3.

[0036] The working principle and usage process of the present utility model:

[0037] First, the operator pulls the pull rod 14 to extract the bolt 12 from the inner surfaces of the movable ladder 1 and the lower fixed ladder 3. Then, the operator adjusts the position of the movable ladder 1 according to the height of the vertical cavity for the installation operation required and inserts the bolt 12 into the inside of the first jack 16 or the second jack 17. Then, the operator releases the pull rod 14. At this time, due to the elastic force of the spring 15, the bolt 12 will be inserted into the inside of the movable ladder 1 along the inner surface of the first jack 16 or the second jack 17. At this time, the movable ladder 1 will be fixed in the current position by the bolt 12.

[0038] Then, the operator integrally fixes and installs the movable ladder 1 and the lower fixed ladder 3 outside the cavity and locks the four brake casters 8. Then, the operator climbs above the standing plate 9 through the movable ladder 1 and the lower fixed ladder 3 and performs the installation operation of the cavity. During this process, the locking of the brake casters 8 will ensure the stability of the whole movable ladder 1 during the cavity installation process, and the guardrail 7 can protect the operator and prevent the operator from falling from both sides of the standing plate 9, greatly improving the operation safety of the operator.
