Detailed implementation manners

[0027] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the drawings in the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0028] Next, in conjunction with the attached Figure 2 To the attached Figure 6 And specific embodiments, the present invention will be elaborated in detail.

[0029] As Figures 2 - 6 shown, the present invention provides a working platform for elevated work, which can enable an operator to move from one side of the equipment to the other side, and is convenient to assemble and has high safety. The equipment mentioned here includes, but is not limited to, the PECVD equipment in the HIT production line. Figure 6 Top view of the working platform for elevated work in this application applied to the HIT production line. It can be seen that when this application is applied to the HIT production line, the operator can enter the inner part of the "mouth" shape through the working platform for elevated work to repair and observe the equipment.

[0030] The working platform for elevated work in this application includes a working platform 2 and two elevated ladder frames 1; the two elevated ladder frames 1 are arranged oppositely, and their tops are connected by a docking component 3 to form a gantry structure, and the working platform 2 is detachably installed on the docking component 3; in other words, the working platform 2 and the two elevated ladder frames 1 are lapped together as a whole. The operator can climb from one of the elevated ladder frames 1 to the working platform 2 for maintenance work, or can choose any one of the elevated ladder frames 1 according to the actual maintenance needs from the working platform 2 to enter the inside or outside of the equipment. The working platform for elevated work in this application straddles the equipment, enabling the working platform 2 to be located directly above the equipment. The operator can stand on the working platform 2 to repair the equipment or enter the production line to maintain and observe the equipment, solving the problems of inconvenience and insecurity for the operator to reach the other side of the equipment in the prior art.

[0031] The docking component in this application is used to connect the tops of the two elevated ladder frames 1 together, similar to building a bridge on the two elevated ladder frames 1, enabling the operator to easily cross the obstacle to achieve position transfer. In some embodiments, referring to Figure 2 , the docking component 3 includes a docking rod 31 and a docking pin 32. The docking rod 31 can be a hollow rod or a solid rod; at least two docking rods 31 are arranged in parallel at the top of each elevated ladder frame 1, and the at least two docking rods 31 are arranged in parallel at intervals. All the docking rods 31 on each elevated ladder frame 1 extend towards the direction of the other elevated ladder frame 1, and the corresponding docking rods 31 on the two elevated ladder frames 1 are connected by the docking pin 32. By way of example, two docking rods 31 are arranged at the top of each elevated ladder frame 1, and the width between the two docking rods 31 is slightly smaller than the width of the working platform 2, that is, the two docking rods 31 are respectively located at both ends in the width direction of the working platform 2. The working platform 2 is lapped on the two docking rods 31, and the docking rods 31 support the working platform 2. The corresponding two docking rods 31 are connected as a whole by the docking pin 32; in other examples, at least three docking rods 31 are arranged at the top of each elevated ladder frame 1, and the width between the outermost two of the at least three docking rods 31 is slightly smaller than the width of the working platform 2, and the outermost two docking rods 31 are respectively located at both ends in the width direction of the working platform 2, realizing stable support for the working platform 2. This application does not limit the structure at the connection between the docking rod 31 and the docking pin 32. Connection methods such as the docking rod 31 being inserted into the docking pin 32 or the docking pin 32 being inserted into the docking rod 31 are all acceptable, as long as the positioning connection of the two corresponding docking rods 31 can be achieved, and they all belong to the protection scope of this application.

[0032] In some embodiments, referring to Figure 3The docking pin 32 includes a shoulder 321 and positioning columns 322 arranged at both ends of the shoulder 321. The positioning columns 322 are generally selected as cylindrical positioning columns. A positioning hole (not shown in the figure) is provided at the end of the docking rod 31 opposite to the positioning column 322. The shape of the positioning hole matches the shape of the positioning column 31. The positioning columns 322 at both ends of the docking pin 32 are respectively inserted into the corresponding positioning holes, and the outer periphery of the positioning column 322 fits the inner wall of the positioning hole. The docking rods 31 at both ends of the docking pin 32 are limited by the shoulder 321. The size of the shoulder 321 is larger than the size of the positioning hole, ensuring that the shoulder 321 will not enter the positioning hole. It can be understood that only when the outer diameter of the shoulder 321 is greater than or equal to the outer diameter of the docking rod 31 can better limiting be achieved. Considering the cost issue, the docking rod 31 in this application uses a tubular structure profile, which has the advantages of convenient processing, low cost and reliable structure.

[0033] In order to better realize the connection between the two corresponding docking rods 31, the docking pin 32 of the present application also includes a frustum 323, which is arranged on an end face of the positioning column 322 away from the shoulder 321, the large end of the frustum 323 is connected to the positioning column 322, and the small end of the frustum 323 is away from the shoulder 321 and the positioning column 322. The positioning column 322 is guided into the positioning hole through the inclined surface of the frustum 323, and is limited by the shoulder 321, so that the relative positions of the two climbing ladders 1 are finally determined. The assembly process is simple, and the installation of the two climbing ladders 1 can be completed without using auxiliary tools such as wrenches.

[0034] In a preferred embodiment, the outer diameter of the shaft shoulder 321 is the same as the outer diameter of the docking rod 31 , so that when the two docking rods 31 are connected as one, the shaft diameters are consistent, which facilitates the connection with the working platform 2 .

[0035] In some embodiments, see Figure 4 , an engaging groove 21 corresponding to the docking rod 31 is provided on the bottom of the work platform 2, and the length of the work platform 2 is adapted to the overall length after the two docking rods 31 are connected with the docking pins 32, and the two docking rods 31 and the corresponding docking pins 32 are both embedded in the engaging groove 21 to improve the stability and reliability of the work platform structure. In a preferred embodiment, the engaging groove 21 is formed by two square tubes 22 fixed to the bottom of the work platform 2, and the two square tubes 22 are welded in parallel to the bottom of the work platform 2, and an engaging groove 21 parallel to the docking rod 31 is formed between the two square tubes 22. During assembly, when the limiting column 33 on the climbing ladder 1 is inserted into the limiting hole on the work platform 2, the docking rod 31 can be guided to automatically embed into the engaging groove 21 at the bottom of the work platform 2, and the assembly is simple and convenient. In other embodiments, the bottom of the work platform 2 is a plane and has a certain thickness, and the engaging groove 21 is directly opened at the bottom of the work platform 2 by wire cutting or other methods.

[0036] In some embodiments, referring to Figure 2 , at least two docking rods 31 on each climbing ladder frame 1 are fixed with upwardly extending limiting columns 33 near one end of the climbing ladder frame 1. Corresponding limiting holes (not shown in the figure) are provided on the lower end surface of the working platform 2. The limiting columns 33 are inserted into the limiting holes, further realizing the limitation of the working platform 2. The limiting column 33 of the present application is a columnar structure with a certain height. Similarly, the limiting hole can at least cover the limiting column 33, but is not limited thereto. The cooperation of the limiting column 33 and the limiting hole also limits the separation of the two climbing ladder frames 1 under external force or human error, further ensuring the safety of the elevated work platform and the operator. It should be noted that if there are only two limiting columns 33 on each climbing ladder frame 1, then the two limiting columns 33 are respectively fixed on the two outermost docking rods 31, and the corresponding limiting holes are located on both sides in the width direction of the lower end of the working platform 2, thereby realizing better limitation of the working platform 2.

[0037] Specifically, the working platform 2 includes a working handrail frame 23. The working handrail frame 23 has an inverted U-shaped structure. The working handrail frame 23 includes a horizontal handrail portion 231 and vertical connecting portions 232 extending downward at both ends of the horizontal handrail portion 231. Preferably, the working handrail frame 23 is an integrally formed tubular structure. Among them, the lower part of the vertical connecting portion 232 forms a limiting hole, and the limiting column 33 is inserted upward into the vertical connecting portion 232, and the limiting column 33 has a certain length in the vertical connecting portion 232 to ensure the stability and safety of the working platform 2 after installation.

[0038] Through the cooperation of the limiting column 33 and the limiting tube of the climbing ladder frame 1 and the working platform 2 of the present application, it is ensured that the two climbing ladder frames 1 will not be accidentally separated under external force or misoperation. Moreover, the elevated work platform of the present application only includes two climbing ladder frames 1, a docking pin 32 and a working platform 2, with a small number of components. It adopts a quick disassembly and assembly design, and no auxiliary tools such as wrenches and bolts are required during the installation and disassembly process. The disassembly and assembly process is simple and convenient. At the same time, through the cooperation of the limiting column 33 and the limiting tube, the bearing capacity of the working platform 2 will also act near the limiting column 33, and will not exert too much gravity on the docking rod 31 and the docking pin 32, ensuring that the docking rod 31 will not be deformed after the operator stands on the working platform 2. Even if the operator leans on the working handrail frame 23 to work, it can also provide sufficient anti-overturning moment to ensure the safety of the operator. In addition, the square tube 22 at the bottom of the working platform 2 will also play a role in bearing the weight during movement, further strengthening the elevated work platform. Figure 5 is the elevated work platform after assembly.

[0039] In a preferred embodiment, a plurality of moving casters 11 are provided at the bottom of the climbing ladder frame 1, and at least two of the plurality of moving casters 11 are braking casters 12. The moving casters 11 facilitate the movement of the elevated work platform during maintenance, and the braking casters 12 facilitate the locking of the elevated work platform after it is moved into place.

[0040] Specifically, the climbing ladder frame 1 includes step plates 13 that are arranged at intervals with a dislocation from bottom to top. The step plate 13 at the highest position is adjacently arranged with the work platform 2. Climbing handrails 14 are provided on both sides of the step plate 13, and the climbing handrails 14 can be adjacently arranged with the work handrail frame 23. In other words, the gaps between the step plate 13 at the highest position and the work platform 2 and between the climbing handrails 14 and the work handrail frame 23 should ensure that the operator cannot pass through.

[0041] The assembly process of the elevated work platform of the present application will be briefly described again below: First, the docking rods 31 of the two climbing ladder frames 1 are easily connected through the docking pins 32 to initially fix the relative positions of the two climbing ladder frames 1; then the work platform 2 is moved above the docking rods 31, and the limit posts 33 on the two climbing ladder frames 1 are inserted into the limit tubes of the work platform 2. After being inserted in place, the docking rods 31 are automatically embedded into the fitting grooves 21 between the two square tubes 22 at the bottom of the work platform 2.

[0042] The above further describes the present invention with the aid of specific embodiments. However, it should be understood that this specific description should not be construed as a limitation on the essence and scope of the present invention. Various modifications made by those of ordinary skill in the art to the above embodiments after reading this specification all fall within the scope protected by the present invention.
