[0022] like Figure 1-5 As shown, a protective device for a crane cab includes a protective mechanism 3, which is connected to the upper end of a cab 1 hinged with a protective door 2, and includes a mounting frame 301 and a protective plate 307. The mounting frames 301 are symmetrically fixed to the upper end of the cab 1, and slots 305 are provided on the inner sides of the mutually symmetrical mounting frames 301. Protective rods 306 are inserted in the slots 305, and the protective rods 306 are connected between the mounting frames 301. A plurality of protective plates 307 are slidably connected between the mounting frames 301, and a buffer assembly 5 is fixed to the lower end of the protective plate 307, and the buffer assembly 5 is connected to the mounting frame 301.

[0023] like Figure 3-5 As shown, in order to utilize the protective plate 307 to protect the cab 1, and at the same time improve the protective effect of the protective plate 307 by improving the buffering effect of the protective plate 307 when receiving an impact, a plurality of mounting grooves 302 are provided on the mounting frame 301, and the mounting grooves 302 run through both sides of the mounting frame 301. Both ends of the protective plate 307 are slidably connected to the mounting grooves 302. Both ends of the protective plate 307 are fixedly connected to the limiting plates 308, and the limiting plates 308 are slidably arranged on the outer side of the mounting frame 301. The buffer assembly 5 includes a damper 501 and a spring 502. A connecting groove 303 is provided at the lower end of the inner wall of the installation groove 302. The damper 501 is fixedly connected to the connecting groove 303. The upper end of the damper 501 is fixedly connected to the protective plate 307. The spring 502 is sleeved outside the damper 501. The two ends of the spring 502 are respectively fixedly connected to the inner wall of the connecting groove 303 and the protective plate 307. The upper end of the protective plate 307 is fixedly connected to a buffer pad 309, and the buffer pad 309 is made of rubber.

[0024] like Figure 1-4 As shown, in order to further improve the protection range and protection effect of the cab 1, a protection component 4 is provided, and the protection component 4 includes a hydraulic rod 401 and a mounting frame 402. A plurality of grooves 304 are provided at the upper end of the mounting frame 301. The hydraulic rod 401 is fixedly connected in the groove 304. The mounting frame 402 is fixedly connected to the upper end of the hydraulic rod 401. A buffer net 403 is fixedly connected in the mounting frame 402.

[0025] When in use, the utility model controls the hydraulic rod 401 to drive the installation frame 402 to rise, thereby lifting the buffer net 403. When a foreign object falls and is about to impact the cab 1, the foreign object is initially buffered by the buffer net 403, and the foreign object impacts the buffer pad 309 to further buffer the impact force of the foreign object. Then the foreign object impacts the protective plate 307, and the protective plate 307 squeezes the damper 501 and the spring 502 after receiving the impact, thereby buffering the protective plate 307, so that the protective plate 307 buffers and resists the impact force of the foreign object, thereby achieving protection of the cab 1.

[0026] In summary: In the embodiment of the utility model, the cab 1 is protected by a protective plate 307 and a guardrail, and at the same time, both ends of the protective plate 307 are slidably connected to the mounting frame 301. By arranging a buffer component 5 at the lower end of the protective plate 307, when the protective plate 307 is impacted, it can be buffered by the buffer component 5, thereby effectively improving the protective effect of the protective plate 307. The protective component 4 connected to the mounting part can further improve the buffering effect on foreign objects, thereby reducing the impact force of foreign objects impacting the cab 1. At the same time, the protective component 4 can intercept and buffer smaller foreign objects impacting the cab 1, and the protective component 4 can be adjusted to shrink according to usage requirements.

The drawings show only one implementation method of the utility model, and the actual structure is not limited thereto. In short, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the invention of the utility model, they should all fall within the protection scope of the utility model.
