Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figures 1-4 In this embodiment of the utility model, an expandable aerial work platform includes a fixed platform component 1. The fixed platform component 1 includes a concave platform 101, a rectangular support frame 102, and an L-shaped support frame 103. Two sets of L-shaped support frames 103 are provided. The two sets of L-shaped support frames 103 are symmetrically distributed with the rectangular support frame 102 as the center. The rectangular support frame 102 and the L-shaped support frame 103 are arranged in a concave shape and fixed to the bottom of the concave platform 101.

[0027] An extension platform component 2 is provided on both sides of the concave platform 101 in the inner area of ​​the L-shaped support frame 103. The extension platform component 2 and the concave platform 101 form a working platform, and the working platform can be extended by the movable adjustment of the extension platform component 2.

[0028] The expansion platform component 2 includes an expansion frame 201, a linear guide rail 202, a slider 203, and an expansion platform 204;

[0029] The linear guide 202 is fixed to the bottom of the extension frame 201, and the slider 203 is installed on the upper surface of the bottom crossbar of the L-shaped support frame 103. The extension frame 201 is distributed inside the L-shaped support frame 103 and the linear guide 202 and the slider 203 are slidably connected.

[0030] The expansion platform 204 is fixed to the top of the expansion frame 201 and distributed below the concave platform 101. The expansion platform 204 forms support for the lower surfaces on both sides of the concave platform 101.

[0031] The extension frame 201, linear guide rail 202, and extension platform 204 are moved horizontally based on slider 203 to adjust the overall standing area of ​​concave platform 101 and extension platform 204.

[0032] A guide rail clamp 207 is also installed on the upper surface of the bottom horizontal bar of the L-shaped support frame 103, and the linear guide rail 202 passes through the top groove area of ​​the guide rail clamp 207.

[0033] In this embodiment, it should be noted that: workers use an external lifting platform to go up to or down from the concave platform 101.

[0034] When performing manual operations, the standing area of ​​the elevated work platform needs to be manually adjusted according to the outer diameter of the gearbox test platform. The operation method is as follows:

[0035] First, manually release the lock of the guide rail clamp 207 on the linear guide rail 202. Then, manually pull the extension frame 201 to move horizontally, thereby realizing the overall movement of the extension frame 201, the linear guide rail 202, and the extension platform 204. After the extension platform 204 is in place, lock the linear guide rail 202 with the guide rail clamp 207 (it should be noted that the guide rail clamp 207 is a common guide rail clamp on the market and is a mature product. Therefore, its internal structure and working principle will not be described in detail here). In this way, the extension function of the aerial work platform is realized.

[0036] Please refer to this carefully. Figures 3-5 A support wheel 206 is installed on the lower surface of the concave platform 101 at a position corresponding to the expansion platform 204. A straight slot 205 is opened on the top of the expansion platform 204 for the support wheel 206 to pass through, and the I-shaped roller groove of the support wheel 206 is in contact with the top of the horizontal bar at the top of the expansion frame 201.

[0037] The top horizontal width of the extension frame 201 is greater than the bottom horizontal width of the extension frame 201, and the top of the extension platform 204 is close to but does not contact the bottom of the concave platform 101.

[0038] In this embodiment: the support wheel 206 is installed below the concave platform 101 and runs on the top horizontal bar of the extension frame 201. The cooperation between the support wheel 206 and the top horizontal bar of the extension frame 201 can increase the force on the concave platform 101, so that the concave platform 101 can withstand a larger load.

[0039] In addition, the structure of the straight groove 205 prevents the expansion platform 204 from contacting or interfering with the support wheel 206 when it moves. The support wheel 206 passing through the straight groove 205 allows the expansion platform 204 to get closer to the concave platform 201. When the expansion platform 204 is unfolded, the working surface of the expansion platform 204 and the working surface of the concave platform 201 can maintain a small height difference, reducing the risk of human tripping.

[0040] Please refer to this carefully. Figure 1 , Figure 2 , Figure 5 Kickboards 3 are fixed to the concave platform 101 at all other edges except for the two sides, and to the edge of the linear guide rail 202 away from the concave platform 101.

[0041] The top rear end of the concave platform 101 and the top side of the extension frame 201 are fitted with guardrails 5 by support clips 4, and a movable gantry 6 is installed in the middle area of ​​the guardrails 5 corresponding to the concave platform 101.

[0042] In this embodiment: the kick plate 3 is designed to prevent tools from falling;

[0043] The guardrail 5 is used to achieve work protection. It should also be noted that the post fixing clamp 4 is a mature product on the market and has the function of adjusting the tightness. By loosening the post fixing clamp 4, the guardrail 104 can be moved up and down to adapt to different height requirements.

[0044] The movable gantry 6 can be rotated and opened to allow staff to enter and exit.

[0045] Please refer to this carefully. Figures 1-5 The linear guide rails 202, sliders 203, and support wheels 206 corresponding to the single set of extension frame 201 are arranged in multiple sets along the longitudinal direction, and the guide rail clamps 207 are arranged in two sets symmetrically.

[0046] In this embodiment: the structure of multiple sets of linear guide rails 202, sliders 203, and support wheels 206 ensures that the movement of the expansion frame 201 remains stable, and the structure of two sets of guide rail clamps 207 provides sufficient locking force to fix the position of the expansion frame 201.

[0047] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
