Description

Technical Field

[0001] This utility model belongs to the field of electrical equipment installation technology, specifically relating to a high-altitude maintenance device for indoor electrical equipment installation. Background Technology

[0002] In indoor electrical equipment installation and maintenance, small aerial work platforms, as commonly used access equipment, have significant functional defects: current standard operating procedures require workers to stand on the platform before starting the lifting mechanism. This passive operating mode reveals systemic deficiencies in practical applications. Specifically, when performing continuous mobile maintenance on electrical equipment in indoor factories and other locations, the limited effective carrying area of ​​the platform (usually no more than 1.5 square meters) prevents maintenance personnel from carrying spare parts, specialized tools, and testing instruments simultaneously. This forces them to perform repeated lifting operations, affecting both maintenance efficiency and the effectiveness of the aerial work platform. To address these technical problems, this utility model proposes an aerial work platform for indoor electrical equipment installation and maintenance, thereby solving these issues. Utility Model Content

[0003] The purpose of this invention is to provide a high-altitude maintenance device for indoor electrical equipment installation, which can solve the above-mentioned technical problems.

[0004] The specific technical solution adopted by this utility model is as follows:

[0005] This utility model provides an indoor electrical equipment installation and maintenance device for elevated access, including a base frame, a lifting platform and a folding staircase assembly. Guide rails are provided on the bottom surface of the lifting platform and inside the base frame. A folding lifting component is provided below the lifting platform. Smooth plates are hinged to the upper and lower sides of the folding lifting component. The two sides of the smooth plates are slidably engaged with the guide rails through notches.

[0009] Preferably, the upper side of the inclined hanging plate is rotatably connected to the hanging pull plate via a support shaft. The hanging pull plate is configured as two pieces and is fixed on both sides of the hanging shaft respectively. The other side of the flip plate is movably fitted with a through shaft. The hanging pull plate is fixed on one side of the through shaft. The hanging pull plate and the flip plate are in a vertical state due to the inclined hanging plate.

[0010] Preferably, two suspension fixing seats are rotatably mounted on the hanging shaft. Both suspension fixing seats are installed on the bottom side of the flip plate on the upper linkage flip assembly, and the two uppermost hanging plates are fixedly installed on the side of the mounting plate.

[0021] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0022] like Figure 1-3 As shown, an indoor electrical equipment installation and maintenance device includes a base frame 1, a lifting platform 2, and a folding stair assembly 3. Guide rails 9 are provided on the bottom surface of the lifting platform 2 and inside the base frame 1. A folding lifting component 4 is provided below the lifting platform 2. Smooth plates 8 are hinged to the upper and lower sides of the folding lifting component 4. The two sides of the smooth plate 8 are slidably engaged with the guide rails 9 through notches. A power lifting assembly is provided between the folding lifting component 4 and the base frame 1.

[0023] The folding staircase assembly 3 includes a mounting plate 31, a linkage flipping assembly 32, and a limiting assembly. Multiple linkage flipping assemblies 32 are provided and connected in parallel. The mounting plate 31 is installed on one side of the bottom surface of the lifting platform 2 and is connected to the uppermost linkage flipping assembly 32.

[0024] One side of the limiting component is set on the movable shaft 33, which is set on the lowest linkage flipping component 32. The other side of the limiting component is set on the rotating shaft 37. The rotating shaft 37 is rotatably mounted on two rotating fixed seats 38. Both rotating fixed seats 38 are mounted on the side of the base frame 1. Support legs 34 are fixed on both sides of the movable shaft 33 and are located on both sides of the limiting component.

[0025] As an optional implementation, the linkage flip assembly 32 includes a flip plate 321, a hanging shaft 322, a sliding shaft 326, an inclined hanging plate 327, and a support shaft 329. The flip plate 321 is located below the hanging shaft 322, and a movable hole 325 is provided through one side of the flip plate 321. The sliding shaft 326 is slidably fitted into the movable hole 325. The inclined hanging plate 327 is configured as two pieces, with the lower side rotatably installed on both sides of the sliding shaft 326 and located on both sides of the flip plate 321. In this way, the sliding shaft 326 can slide to both sides within the movable hole 325, thereby causing the flip plate 321 to be vertical or flipped between the two inclined hanging plates 327, achieving the effect of folding and storage.

[0026] See attached document Figure 3 The upper side of the inclined suspension plate 327 is rotatably connected to the suspension plate 324 via the support shaft 329. The suspension plate 324 is configured as two pieces and is fixed on both sides of the suspension shaft 322. The other side of the flip plate 321 is movably fitted with a through shaft 328. The suspension plate 324 is fixed on one side of the through shaft 328. The suspension plate 324 and the flip plate 321 are in a vertical state relying on the inclined suspension plate 327. In this way, the flip plate 321 can be driven by the lifting platform 2, so that the suspension shaft 322 drives the suspension plate 324 and the inclined suspension plate 327 to automatically flip the flip plate 321 to a horizontal state, which is convenient for climbing operations.

[0027] Furthermore, two suspension mounting seats 323 are rotatably installed on the hanging shaft 322. Both suspension mounting seats 323 are installed on the bottom side of the flip plate 321 on the upper linkage flip assembly 32. The two uppermost hanging plates 324 are fixedly installed on the side of the mounting plate 31. This design allows the uppermost linkage flip assembly 32 to be installed on the mounting plate 31, thereby flipping the folding stair assembly 3 in accordance with the lifting operation of the lifting platform 2, which facilitates the climbing operation of maintenance personnel.

[0028] See attached document Figure 2 The limiting assembly includes a folding link 35 and a limiting plate 36. One side of the folding link 35 is movably sleeved on the movable shaft 33 and located between the support leg 34 and the lowest flip plate 321. The movable shaft 33 is fixedly passed through the lowest flip plate 321. The other side of the folding link 35 is fixed to one side of the rotating shaft 37. In this way, the folding link 35 can be folded and flipped by relying on the rotating shaft 37 and the movable shaft 33.

[0029] Furthermore, a limiting plate 36 is disposed on the side of the folding connecting rod 35, and a positioning screw 36a is fitted on one side of the limiting plate 36. The positioning screw 36a is threadedly connected to one of the folding connecting rods 35. Multiple parallel insertion holes 35a are opened on the other side of the folding connecting rod 35. An adjusting screw 36b is fitted inside one of the insertion holes 35a. The adjusting screw 36b is threadedly connected to the other side of the limiting plate 36. This design allows the limiting plate 36 to be rotated and adjusted on one side by means of the positioning screw 36a, thereby driving the adjusting screw 36b on the other side of the limiting plate 36 to be threadedly connected to the insertion hole 35a of the folding connecting rod 35 after folding. This limits the adjustment of multiple linkage flipping components 32, improving the stability of the operator when climbing.

[0030] Furthermore, the power lifting assembly includes a lifting rod 5, a hydraulic rod 6, and a horizontal shaft 7. The extended end of the hydraulic rod 6 is rotatably mounted on the lifting rod 5, and the lifting rod 5 is mounted at the folding center of the folding lifting component 4. The fixed end of the hydraulic rod 6 is rotatably mounted on the horizontal shaft 7, and the horizontal shaft 7 is fixed inside the base frame 1. This design allows the power lifting assembly to push and adjust the folding lifting component 4, thereby driving the lifting platform 2 to perform lifting operations.

[0031] Using the above structure, the hydraulic rod 6 pushes the lifting rod 5 to drive the folding lifting component 4 to merge and lift the lifting platform 2. At the same time, the lifting platform 2 drives the mounting plate 31 on the folding stair assembly 3 to rise synchronously. The mounting plate 31 drives the hanging plate 324 of the uppermost linkage tilting assembly 32 to rise, thereby driving the sliding shaft 326 on the inclined hanging plate 327 to slide in the movable hole 325, so that the tilting plate 321 is in a horizontal state. The uppermost linkage tilting assembly 32 drives the connected linkage tilting assembly 32 to rise continuously, successively driving each linkage tilting assembly to rise. The flip plate 321 on component 32 is flipped to a horizontal position; then the folding linkage 35 on the limiting component is adjusted to support the lowest linkage flip component 32, and the limiting plate 36 is rotated by the positioning screw 36a so that the adjusting screw 36b on the other side of the limiting plate 36 corresponds to the insertion hole 35a. Then the adjusting screw 36b is tightened and inserted into the insertion hole 35a, thereby positioning the lower side of multiple linkage flip components 32; this is to ensure stability when maintenance personnel climb to a height, thereby improving the efficiency of component replacement during maintenance.
