[0017] The technical solution of this utility model will be further described in detail below through embodiments and in conjunction with the accompanying drawings.

[0018] like Figure 1-2As shown, a multi-functional aerial work platform includes a base plate 1 and side railings 2. The side railings 2 and the base plate 1 enclose each other to form a work platform. Inside the side railings 2, above the base plate 1, are an operating platform 21 and a storage cabinet 22. The operating platform 21 is located on the upper inner side of the side railings 2 and is used by workers to operate and control the movement of the work platform and control other equipment. The storage cabinet 22 can store tools and other items to prevent them from falling off the work platform and causing falling objects. Above the base plate 1 is a support plate 3 for workers to stand on and which can move up and down. When a worker walks onto the work platform and stands on the support plate 3, the support plate 3 moves downward under pressure. A pressure sensor 11 is located in the middle of the base plate 1 corresponding to the area below the support plate 3. Above the pressure sensor 11, corresponding to the bottom surface of the support plate 3, is a pressure block 31 that can contact the pressure sensor 11. When the support plate 3 is pressed down... The movement will cause the pressure block 31 to move down together until the pressure block 31 contacts the pressure sensor 11. The pressure sensor 11 is a prior art technology. When an external force is applied to the sensing position of the pressure sensor 11, the pressure sensor 11 can sense and transmit a pressure value signal. If the load on the support plate 3 is within the normal range, the pressure value sensed by the pressure sensor 11 is within the normal range. If the load on the support plate 3 is within the overload range, the pressure value sensed by the pressure sensor 11 is within the overload range. The pressure sensor 11 transmits an overload signal to remind the staff in real time to avoid overload. There is a gap between the outer wall of the support plate 3 and the inner wall of the side railing 2. The gap between the support plate 3 and the support bracket of the side railing 2 makes the up and down floating of the support plate 3 smoother and avoids contact and friction that may cause the support plate 3 to jam and affect the pressure detection accuracy of the pressure sensor 11.

[0019] like Figure 2-3As shown, the bottom surface of the support plate 3 is provided with a slot 32 that mates with the pressure block 31. The slot 32 on the bottom surface of the support plate 3 is used to accommodate the pressure block 31, allowing the pressure block 31 to move up and down within the slot 32. This increases the mobility of the pressure block 31 when the support plate 3 moves down and the pressure block 31 presses down on the pressure sensor 11, preventing excessive movement of the support plate 3 and thus avoiding damage to the pressure sensor 11 caused by the pressure block 31. It also increases the buffer space. The slot 32 is provided with multiple first telescopic springs 33 connected to the pressure block 31. The first telescopic springs 33 can increase the automatic reset capability and buffer capability of the pressure block 31, preventing damage to the pressure sensor 11 and ensuring that the pressure sensor 11 can sense the pressure range. At the same time, it can drive... The dynamic pressure block 31 automatically resets to achieve repeated action. Multiple fixed posts 34 are provided on the bottom surface of the support plate 3. The base plate 1 is provided with a fixed cylinder 12 that slides with and is coaxially arranged with the fixed posts 34. The fixed cylinder 12 is provided with a second telescopic spring 121 connected to the end of the fixed post 34. The fixed posts 34 and the fixed cylinder 12 are provided to increase the limiting guidance for the support plate 3 when it moves up and down, ensure the stability of the support plate 3 when it moves up and down, avoid the support plate 3 from shifting laterally and affecting the detection accuracy of the pressure sensor 11, and at the same time avoid the difficulty for the staff to stand and work on the support plate 3. The second telescopic spring 121 allows the support plate 3 to automatically reset to the top side for the next load test.

[0020] like Figure 1-4 As shown, the inner wall of the side railing 2 is provided with multiple longitudinally arranged limiting sliders 23. The longitudinal length of the limiting sliders 23 is greater than the thickness of the support plate 3. The side wall of the support plate 3 is provided with limiting grooves 35 that cooperate with the limiting sliders 23. The support plate 3 can move stably up and down under the limiting guidance of the limiting sliders 23 through the limiting grooves 35, avoiding the deviation of the support plate 3 during up and down movement, which would affect the stability of the workers and the accuracy of pressure detection. The upper end of the limiting sliders 23 is provided with a limiting plate 24. The bottom surface of the limiting plate 24 can abut against the top surface of the support plate 3. The limiting plate 24 limits the highest movable position of the support plate 3, preventing the support plate 3 from floating too much up and down under the action of the second telescopic spring 121, which would make it difficult for the workers to stand. To ensure stability, a threaded rod 25 is threaded through the limiting plate 24 and connected to the limiting plate 24. The lower end of the threaded rod 25 can abut against the top surface of the support plate 3. A driving block 251 is provided at the upper end of the threaded rod 25. The threaded rod 25 is designed so that after the support plate 3 moves down to its position, the threaded rod 25 can be rotated by the driving block 251, so that the lower end of the threaded rod 25 moves down until it abuts against the top surface of the support plate 3. This maintains the stability of the support plate 3 during high-altitude operations and prevents the support plate 3 from floating, which would affect the stability of the workers and their normal work. After the work is completed and the workers return to the ground, the threaded rod 25 can be rotated in the opposite direction to remove the limiting position of the lower end of the threaded rod 25 against the top surface of the support plate 3, so that the support plate 3 can automatically reset.

[0021] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
