[0036] See also Figure 2 As shown, a crane bridge for construction, the ice scraper blade 46 is arranged toward the outer wheel 44 of the driving wheel group, a support block 15 is provided on the top of the driving assembly 40, the support block 15 is in a door shape, the bottom of the left and right ends of the support block 15 are rotatably connected to the two rotating shafts 3 45, the top of the support block 15 is fixedly connected to the top inner wall of the protective shell 14, the support block 15 is mainly used to support the weight of the lifting trolley 13, and the bottom of the lifting trolley 13 will not fall on the area where the protective shell 14 does not overlap with the support block 15.

[0037] Working principle:

[0038] Step 1: When the area between the protective shell 14 and the groove 1 is covered with snow and frozen, the heating device on the outer wall of the protective shell 14 starts to work, and stops working when the lifting trolley 13 can move;

[0039] Step 2: When the lifting trolley 13 starts to move, the driving wheel group drives the gear 2 41 to rotate, the gear 2 41 drives the gear 1 31 to rotate, and the gear 1 31 drives the fan gear 21 to rotate. When the lifting trolley 13 is just started, the counterweight block 25 abuts against the guide rail 12, the spring telescopic rod 24 is compressed, and the fan gear 21 and the gear 1 31 are meshed with each other. As the fan gear 21 rotates, the turntable 23 rotates accordingly, driving the spring telescopic rod 24 to rotate to the outside of the turntable 23. The top of the side wall, at this time, the counterweight 25 is pulled up, when the sector gear 21 is no longer meshed with the gear 1 31, the center of gravity of the counterweight 25 is located on the side of the turntable 23 close to the ice scraper assembly 30, at this time, the counterweight 25 immediately falls down under the action of gravity to hammer the ice layer on the surface of the guide rail 12, when the counterweight 25 hammers the surface of the guide rail 12, the spring telescopic rod 24 can absorb the reaction force of the hammering, at this time the sector gear 21 will mesh with the gear 1 31 again;

[0040] Step 3: When the gear 1 31 rotates, the rotating shaft 2 32 is driven to rotate, and the rotating shaft 2 32 drives the fixed plates 33 at both ends to rotate, and the fixed plates 33 drive the top and bottom ice scrapers 1 34 to rotate to scrape the ice layer that has been hammered. Due to the arc-shaped structure of the blade surface of the ice scraper 1 34, the scraped ice is sent to both sides of the ice scraper 1 34, that is, a part of it falls from the channel 1, and the other part is sent to the area between the groove 1 and the guide rail 12;

[0041] Step 4: During the ice-shoveling operation, the hub 43 of the driving wheel set begins to heat up. As the lifting trolley 13 moves, the ice-shoveling blade 46 shovels the ice and snow in the groove 1. The hub 43 of the driving wheel set can also accelerate the melting of the ice layer on the surface of the guide rail 12. Due to the arc-shaped structure of the blade surface of the ice-shoveling blade 46, the shoveled ice and snow are sent to the outside of the beam 11. The baffle 47 also prevents ice and snow from being pushed onto the guide rail 12 during this period.
