[0025] like Figure 1-8 As shown, a bridge crane cab includes a cab body 1 and a cleaning mechanism 3 connected to the cab body 1. A main observation plate 101 is fixed to the front end of the cab body 1, and auxiliary observation plates 102 are fixed to both sides of the cab body 1. The cleaning mechanism 3 includes a first cleaning frame 304 and a scraping assembly 5. The first cleaning frame 304 slides vertically on the outside of the cab body 1 to clean the outside of the main observation plate 101 and the auxiliary observation plates 102. Both the main observation plate 101 and the auxiliary observation plates 102 are made of transparent material.
[0026] like Figure 2 , 3As shown in Figures 5 and 6, the cleaning mechanism 3 further includes a motor 301 and a limiting rod 303. A screw 302 is fixedly connected to the output end of the motor 301. A first slider 305 and a limiting block 306 are fixedly connected to both ends of the first cleaning frame 304, respectively. The first slider 305 is threaded onto the screw 302, and the limiting block 306 is slidably connected to the limiting rod 303. A first scraper 307 is connected to the inner wall of the first cleaning frame 304. The first scraper 307 slidably adheres to the outer sides of the main observation plate 101 and the auxiliary observation plate 102. First mounting shells 2 are symmetrically fixed to both sides of the cab body 1. The motor 301 is fixedly connected to the first mounting shell 2 on one side of the cab body 1. A [missing information - likely a design feature] is provided on the outer side of the first mounting shell 2 on one side of the cab body 1. Heat dissipation holes 202 are used for heat dissipation of motor 301. First mounting shells 2 on both sides of the cab body 1 are provided with first sliding grooves 201. The first slider 305 and the limiting block 306 are slidably engaged in the two first sliding grooves 201 respectively. The screw 302 and the limiting rod 303 are vertically connected to the two first sliding grooves 201 respectively. The screw 302 is rotatably connected to the inner wall of the first sliding groove 201, and the limiting rod 303 is fixedly connected to the inner wall of the first sliding groove 201. Driven by motor 301, the first cleaning frame 304 fastened to the front end of the cab body 1 slides vertically, thereby causing the first scrapers on the three inner walls of the first cleaning frame 304 to scrape and clean the outer side of the main observation plate 101 and the auxiliary observation plate 102. The first scrapers are made of rubber.
[0027] like Figure 4 As shown, the auxiliary observation plate 102 has a first connecting groove 103 and a second connecting groove 104 vertically distributed on both sides. The first magnet 308 and the second magnet 503 are vertically slidably fitted in the first connecting groove 103 and the second connecting groove 104, respectively, to improve the stability of the vertical movement of the first magnet 308 and the second magnet 503.
[0028] like Figure 2 , 3As shown in FIGS. 7 and 8, the scraping and sweeping assembly 5 includes a second cleaning frame 501. The first cleaning frame 304 and the second cleaning frame 501 are arranged in an "L" - shaped structure with an inner - outer distribution. The first cleaning frame 304 and the second cleaning frame 501 are respectively fixedly connected with a first magnet 308 and a second magnet 503 that attract each other through a connecting rod. The first magnet 308 and the second magnet 503 are made of strong magnetic materials. The first cleaning frame 304 drives the second cleaning frame 501 to slide vertically inside the cab body 1 to clean the inner sides of the main observation plate 101 and the secondary observation plate 102. Both sides of the inner wall of the cab body 1 are fixedly connected with second mounting shells 4. Each of the two second mounting shells 4 is provided with a vertically - arranged second chute 401. Both ends of the second cleaning frame 501 are fixedly connected with second sliders 504 that slide in the second chute 401. The outer side of the second cleaning frame 501 is connected with a second scraping blade 502. The second scraping blade 502 slides and fits on the inner sides of the main observation plate 101 and the secondary observation plate 102. Both sides of the second slider 504 are automatically rotatably connected with balls 505. Both sides of the inner wall of the second chute 401 are provided with rail grooves 402. The balls 505 are vertically movably fitted in the rail grooves 402. By the movement of the balls 505 between the second slider 504 and the rail grooves 402, the frictional resistance of the second slider 504 is reduced. Under the adsorption effect of the first magnet 308 and the second magnet 503, when the first cleaning frame 304 moves vertically, it带动 the second cleaning frame 501 to move vertically inside the cab body 1, and further enables the second scraping blade 502 to scrape and clean the inner sides of the main observation plate 101 and the secondary observation plate 102. The second scraping blade 502 is made of rubber material.
[0029] When the present utility model is in use, the output end of the motor 301 drives the screw 302 to rotate, thereby带动 the first slider 305 to slide vertically in the first chute 201 on one side of the cab body 1. At the same time, the limiting block 306 slides and is limited on the limiting rod 303 in the first chute 201 on the other side of the cab body 1. The first cleaning frame 304 is带动 to vertically lift and lower at the front end of the cab through the first slider 305 and the limiting block 306, and further带动 the first scraping blade 307 to scrape and clean the outer sides of the main observation plate 101 and the secondary observation plate 102. When the first cleaning frame 304 vertically lifts and lowers, the first cleaning frame 304带动 the first magnet 308 fixedly connected to it to slide vertically in the first connection groove 103, and further enables the second magnet 503 that attracts the first magnet 308 to slide vertically in the second connection groove 104. The second cleaning frame 501 is带动 to vertically lift and lower inside the cab body 1 through the second magnet 503. At the same time, the second slider 504 slides in the second chute 401, enabling the balls 505 to roll between the second slider 504 and the rail grooves 402 to reduce friction. The second cleaning frame 501 vertically lifts and lowers inside the cab body 1, and further带动 the second scraping blade 502 to clean the inner sides of the main observation plate 101 and the secondary observation plate 102.

This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
