[0005] 1. Technical issues to be solved

[0006] In view of the deficiencies in the prior art, the utility model provides a snow removal device for bridge maintenance, which solves the technical problem that the above-mentioned snow removal device uses a snow brush to clear the snow on the road, but the snow brush is relatively soft and cannot perform the cleaning operation when the snow on the road is compacted or the road surface is frozen.

[0007] (II) Technical solution

[0008] In order to achieve the above objectives, the present invention is implemented through the following technical solutions:

[0009] A snow removal device for bridge maintenance comprises an outer shell, two rollers are rotatably mounted on both sides of the outer shell, a spreading shovel is fixedly mounted on the side end of the outer shell, a rotating rod is rotatably mounted inside the outer shell, a first gear is fixedly mounted on the side ends of the two rollers, two second gears are symmetrically fixedly mounted on both sides of the rotating rod, a plurality of transmission rods are rotatably mounted on the rotating rod, a plurality of guide barrels are fixedly mounted inside the outer shell; the second gear is meshed with the first gear, a sliding rod is slidably mounted inside the guide barrel, a plurality of ice-breaking cones are fixedly mounted on the bottom end of the sliding rod; the top end of the sliding rod is rotatably connected to the transmission rod, and a fixing pin is mounted on the side end of the outer shell.

[0010] Preferably: a bolt is installed at the bottom end of the fixing pin.

[0011] Preferably: a limit plate is fixedly installed on the top end of the spreading shovel.

[0012] (III) Beneficial effects

[0013] 1. Unscrew the bolt, pull out the fixing pin, connect the device to the rear of the vehicle, insert the fixing pin back, and tighten the bolt. When the vehicle moves forward, the roller rotates, and the first gear at the side end of the roller also rotates at the same time, and the second gear rotates by meshing with the second gear. The second gear rotates while driving the rotating rod to rotate. The rotation of the rotating rod causes the sliding rod to slide up and down inside the guide barrel through the transmission rod. The sliding rod that slides up and down causes the ice-breaking cone to continuously hit the ice or snow on the road surface. After breaking the ice surface or the agglomerated snow, the two inclined surfaces of the spreading shovel push the ice to both sides of the bridge to complete the snow removal. The roller drives the ice-breaking cone to hit up and down to complete the ice-breaking treatment of the road surface, thereby achieving the effect of breaking ice and removing snow.

[0014] 2. During the ice-breaking process, since the circumference of the first gear is greater than that of the second gear, the rotation speed of the rotating rod will increase when the roller rotates. During the rotation of the rotating rod, the two adjacent sliding rods will slide alternately, so that the two adjacent ice-breaking cones will hit the ice surface alternately. Combined with the high-speed rotating rotating rod, the ice-breaking efficiency of the ice-breaking cone will be greatly improved. The limit plate at the top of the spreading shovel will intercept the snow that spreads to the top of the spreading shovel to prevent the snow from falling back into the cleared road surface.

[0021] The embodiment of the present application provides a snow removal device for bridge maintenance, which effectively solves the above-mentioned snow removal device. The snow on the road is cleared by a snow brush. The snow brush is relatively soft. When the snow on the road is compacted or the road surface is frozen, the cleaning operation cannot be performed. The bolt is unscrewed, the fixing pin is pulled out, the device is connected to the rear of the vehicle, and the fixing pin is inserted back. The bolt is tightened. When the vehicle moves forward, the roller rotates, and the first gear at the side end of the roller also rotates at the same time. By meshing with the second gear, the second gear rotates. The rotation of the second gear also drives the rotating rod to rotate. The rotation of the rotating rod causes the sliding rod to slide up and down inside the guide barrel through the transmission rod. The sliding rod that slides up and down causes the ice-breaking cone to continuously move against the road surface. The ice or snow will be hit, and after the ice surface or the agglomerated snow is broken, the two inclined surfaces of the spreading shovel will push the ice to both sides of the bridge to complete the snow removal. The roller drives the ice-breaking cone to hit up and down to complete the ice-breaking treatment of the road surface, achieving the effect of breaking ice and removing snow. In the ice-breaking process, since the circumference of the first gear is greater than the circumference of the second gear, the rotation speed of the rotating rod will increase when the roller rotates. During the rotation of the rotating rod, the two adjacent sliding rods will slide alternately, so that the two adjacent ice-breaking cones will hit the ice surface alternately. Combined with the high-speed rotating rod, the ice-breaking efficiency of the ice-breaking cone will be greatly improved. The limit plate at the top of the spreading shovel will intercept the snow that spreads to the top of the spreading shovel to prevent the snow from falling back into the cleared road surface.

[0022] Example

[0023] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the technical solution in the embodiment of the present application effectively solves the technical problem that the snow removal device mentioned above uses a snow sweeping brush to clear the snow on the road. The snow sweeping brush is relatively soft. When the snow on the road is compacted or the road surface is icy, the cleaning operation cannot be performed. The overall idea is as follows:

[0024] In view of the problems existing in the prior art, the utility model provides a snow removal device for bridge maintenance, comprising a shell 1, two rollers 2 are symmetrically rotatably installed on both sides of the shell 1, a spreading shovel 3 is fixedly installed on the side end of the shell 1, a rotating rod 5 is rotatably installed inside the shell 1, and a first gear 4 is fixedly installed on the side ends of the two rollers 2.

[0025] Two second gears 6 are symmetrically fixedly installed on both sides of the rotating rod 5, and multiple transmission rods 7 are rotatably installed on the rotating rod 5. Multiple guide barrels 11 are fixedly installed inside the shell 1; the second gear 6 is meshed with the first gear 4, and a slide rod 8 is slidably installed inside the guide barrel 11.

[0026] A plurality of ice-breaking cones 9 are fixedly installed at the bottom end of the slide rod 8; the top end of the slide rod 8 is rotatably connected to the transmission rod 7, a fixing pin 12 is installed at the side end of the shell 1, a bolt 13 is installed at the bottom end of the fixing pin 12, and a limiting plate 14 is fixedly installed at the top end of the spreading shovel 3.

[0027] Working principle:

[0028] The first step is to unscrew the bolt 13, pull out the fixing pin 12, connect the device to the rear of the vehicle, then insert the fixing pin 12 back, and tighten the bolt 13. When the vehicle moves forward, the roller 2 rotates, and the first gear 4 at the side end of the roller 2 also rotates at the same time, and the second gear 6 is engaged with the second gear 6 to rotate. The second gear 6 will drive the rotating rod 5 to rotate at the same time. The rotation of the rotating rod 5 will cause the sliding rod 8 to slide up and down inside the guide barrel 11 through the transmission rod 7. The sliding rod 8 that slides up and down causes the ice-breaking cone 9 to continuously hit the ice or snow on the road surface. After breaking the ice surface or the agglomerated snow, the two inclined surfaces of the spreading shovel 3 will push the ice to both sides of the bridge to complete the snow removal. The ice-breaking cone 9 is driven by the roller 2 to hit up and down to complete the ice breaking process on the road surface, thereby achieving the effect of breaking ice and removing snow.

[0029] In the second step, during the ice-breaking process, since the circumference of the first gear 4 is greater than that of the second gear 6, the rotation speed of the rotating rod 5 will increase when the roller 2 rotates. During the rotation of the rotating rod 5, the two adjacent sliding rods 8 will slide alternately, so that the two adjacent ice-breaking cones 9 will hit the ice surface alternately. Combined with the high-speed rotating rotating rod 5, the ice-breaking efficiency of the ice-breaking cones 9 will be greatly improved. The limiting plate 14 at the top of the spreading shovel 3 will intercept the snow that spreads to the top of the spreading shovel 3 to prevent the snow from falling back into the cleared road surface.

[0030] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly explaining the present invention, and are not intended to limit the implementation methods. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from this are still within the scope of protection of the present invention.
