[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model;

[0021] Please see Figures 1-4 In this utility model, the combined aerial work platform includes a vehicle body 1, a lifting mechanism 2 installed on the top of the vehicle body 1, a main work platform 3 fixedly installed on the top of the lifting mechanism 2, a secondary work platform 4 slidably installed on the left side of the main work platform 3, a snap-fit ​​component 5 installed on the secondary work platform 4, the snap-fit ​​component 5 and the main work platform 3 pressing together to limit the secondary work platform 4, and an auxiliary support mechanism 6 installed on the left side of the vehicle body 1.

[0022] In this invention, the vehicle body 1 serves as the support for the device, facilitating the movement of the entire device. During use, the worker first lines up on the main work platform 3, then moves the vehicle body 1 to the work area, and then operates the lifting mechanism 2 to raise the main work platform 3 to the working height. In a single-person operation scenario, the auxiliary work platform 4 remains stationary with the main work platform 3, allowing only single-person operation. When the work environment requires two-person operation, the locking mechanism 5 is pulled to release the auxiliary work platform 4 from its position, and then the auxiliary work platform 4 is horizontally pushed outwards to increase the carrying space. Simultaneously, the auxiliary support mechanism 6 is activated to ground the platform, making the unfolded platform more stable. This achieves the advantages of the device having a variable carrying space, more flexible expansion, and an increased range of applicable working environments. It solves the problem in existing technologies where different high-altitude work tasks may require work platforms of different shapes and functions, while single-type high-altitude work platforms have limited application scenarios and are difficult to flexibly adapt to different work scenarios, resulting in poor usability.

[0023] Please see Figure 2 The snap-fit ​​component 5 includes an I-shaped handle 51 and two tension springs 52. The bottom end of the I-shaped handle 51 passes through and slides into the interior of the sub-worktable 4 and contacts and engages with the outer side of the main worktable 3. The top ends of the two tension springs 52 are fixedly connected to the inner side of the I-shaped handle 51, and the bottom ends of the two tension springs 52 are fixedly connected to the top of the sub-worktable 4.

[0024] In this utility model, by grasping the I-shaped handle 51 and pulling it upward, and stretching the tension spring 52, the bottom of the I-shaped handle 51 is separated from the main worktable 3, so that the auxiliary worktable 4 can be flexibly pushed out and unfolded, making the expansion operation more convenient and flexible.

[0025] Please see Figure 1 The main workbench 3 has a main insertion rod 31 fixedly connected to the top left side of the main workbench 3. The other end of the main insertion rod 31 passes through and slides to the inside of the auxiliary workbench 4. The bottom end of the I-shaped handle 51 is pressed against the main insertion rod 31. The auxiliary workbench 41 is fixedly connected to the right side of the bottom of the auxiliary workbench 4. The other end of the auxiliary insertion rod 41 passes through and slides to the inside of the main workbench 3.

[0026] In this invention, the main insertion rod 31 and the auxiliary insertion rod 41 are arranged vertically and horizontally in a symmetrical manner, which makes the support effect between the main worktable 3 and the auxiliary worktable 4 more stable and the structure more robust.

[0027] Please see Figure 1 Among them: a ladder 7 is installed on one side of the main workbench 3, a control handle 8 is fixedly installed inside the main workbench 3, and a safety lock rod 9 is fixedly installed inside the main workbench 3.

[0028] In this utility model, the ladder 7 facilitates personnel to climb onto the main workbench 3, and the control handle 8 is used to control the lifting mechanism 2 to drive the main workbench 3 to rise and fall. The safety lock rod 9 allows the staff to attach the safety rope for safety protection.

[0029] Please see Figure 1 , Figure 3 and Figure 4 The auxiliary support mechanism 6 includes a vertical hydraulic cylinder 61, an integrated frame 62, and three grounding rods 63. The bottom of the vertical hydraulic cylinder 61 is fixedly installed on the vehicle body 1, and the top of the vertical hydraulic cylinder 61 is fixedly connected to the integrated frame 62. The inner side of the integrated frame 62 is slidably connected to the outer side of the vehicle body 1. The tops of the three grounding rods 63 are all fixedly connected to the bottom of the integrated frame 62. The three grounding rods 63 are located on both sides and the left end of the vehicle body 1, respectively.

[0030] In this utility model, the vertical hydraulic cylinder 61 is activated to drive the integrated frame 62 to rise and fall vertically, causing the grounding rod 63 to contact the ground, thereby achieving auxiliary support and providing stable support for the expanded work platform.

[0031] Please see Figure 1 The lifting mechanism 2 includes a main hydraulic cylinder 21 and a lifting sleeve 22. The bottom end of the main hydraulic cylinder 21 is fixedly installed on the top of the vehicle body 1, and the top end of the main hydraulic cylinder 21 is fixedly connected to the lifting sleeve 22.

[0032] In this invention, the main hydraulic cylinder 21 is activated to drive the main worktable 3 to rise and fall, and the lifting sleeve 22 extends and retracts accordingly, thereby achieving replication support and improving the stability of the main worktable 3.

[0033] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
