[0027] Example 1

[0028] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4A boom-type aerial work platform guard includes a turntable mounting surface 1 and a protective door 2. The front surface of the protective door 2 has a first through groove 3 extending to the rear side of the protective door 2. A mounting frame 4 is fixedly connected to the rear surface of the protective door 2. A second through groove 5 is provided on the mounting frame 4, and the second through groove 5 communicates with the first through groove 3. A cabinet door 6 is slidably connected between the upper and lower inner walls of the second through groove 5. Two locking grooves 7 are provided on the rear surface of the cabinet door 6. A control block 8 is fixedly connected to the front surface of the cabinet door 6. A pressing block 9 is provided on the front surface of the protective door 2. A sliding rod 10 is fixedly connected to the rear surface of the pressing block 9. The rear end of the sliding rod 10 slides through the rear surface of the protective door 2. A locking component is provided on the sliding rod 10. The cabinet door 6 is unlocked by pressing the pressing block 9 in conjunction with the locking component. Then, the cabinet door 6 can be opened by controlling the control block 8 without opening the entire protective door 2. This effectively reduces the complexity of daily operation and avoids the problem of the large space required to open the entire protective door 2 during daily work.

[0029] Furthermore, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, the locking assembly includes a mounting plate 11, which is fixedly connected to the rear ends of two sliding rods 10. The mounting plate 11 is cross-shaped. Two locking rods 12 are fixedly connected to the front surface of the mounting plate 11. The front ends of the two locking rods 12 slide through the interior of the second through groove 5. A guide rod 13 is fixedly connected to the rear surface of the mounting frame 4. The rear end of the guide rod 13 slides through the rear surface of the mounting plate 11. A limiting plate 14 is fixedly connected to the rear end of the guide rod 13. The front surface of the limiting plate 14 is flush with the mounting frame 4. A spring 15 is fixedly connected between the frame 4. A valve assembly mounting bracket 16 is provided on the turntable mounting surface 1. A pneumatic spring 17 is provided between the turntable mounting surface 1 and the protective door 2. A latch 18 is installed on the valve assembly mounting bracket 16. A lock 19 is installed on the protective door 2. The lock 19 and the latch 18 are compatible.

It can also limit the protective door 2 to prevent rebound and accidental closure, thus ensuring the safety of the staff.

[0030] The usage process of the boom-type aerial work platform protective cover provided by this utility model is as follows:

[0031] When performing assembly and maintenance work requiring a large operating space, the entire protective door 2 can be opened by unlocking the latch 18. After opening, the pneumatic spring 17 not only saves effort but also limits the movement, preventing the protective door 2 from rebounding or accidentally closing and causing injury to workers. When adjusting parameters and controlling the control panel, the sliding rod 10 can be moved backward by pressing the block 9. When the sliding rod 10 moves, it simultaneously moves the mounting plate 11, which in turn moves the two locking rods 1. 2. After the locking lever 12 moves, it disengages from the locking groove 7. At this time, the cabinet door 6 can be moved by the control block 8. At the same time, when the mounting plate 11 moves, the spring 15 will be compressed to prepare for subsequent reset. After the cabinet door 6 is fully opened, the pressing block 9 can be released, and the elastic force of the spring 15 can make the pressing block 9, sliding rod 10, mounting plate 11 and locking lever 12 reset. After the locking lever 12 resets, it re-enters the interior of the locking groove 7 to lock the cabinet door 6. At this time, daily work can be carried out without opening the entire protective door 2, reducing the space occupied.
