Description
Technical field
This is practical to belong to the curing means in paving and to equipment or device technique field that the road surface of finishing processes, is specifically related to remove utensil and equipment that airport and road accumulated snow are used.
Background technology
In the north, cold season in winter, temperature is lower, and in middle and lower reaches area, China the Yellow River, winter temperature reaches-10 ℃, in the northwest with northeast temperature is minimum reaches-30 ℃, snow can not in time melt when snowing, and has amassed very thick snow on road and aerodrome, accumulated snow often occurs and reaches 30～40cm, in order to guarantee traffic safety and flight safety, all highway close traffics, airport sealing.
The traditional removing road and the method for airport accumulated snow are to adopt ARTIFICIAL FORCE to remove clean with accumulated snow and clean ice sheet that spades, besom will be deposited on road and the airport, open to traffic and open airport then, because highway geometry is long, speedway particularly, what have reaches thousands of kilometer, the aerodrome cover an area of thousands of mus, mobilizing people up to ten thousand to need for a long time could be clean with the Snowremoval on road and aerodrome, ability open to traffic and flight have brought great economic loss to country.At present, the maintenance unit on highway maintenance unit and aerodrome does not also have the special-purpose removing road and the plant equipment of aerodrome accumulated snow, usually remove the accumulated snow on road and aerodrome with bulldozer or loader, the negligible amounts of bulldozer and loader, the Snowremoval with road and aerodrome is clean in time.In addition, bulldozer or loader are easy to road surface and road, aerodrome face are damaged when rooting out accumulated snow, easily road surface and road face are damaged by pressure when particularly crawler dozer is walked on road and aerodrome.
The patent No. is 01272373.8, denomination of invention is the Chinese patent of " Salt distributing vehicle for snow removing ", its primary structure is that the snow shoveling plate of snow removing shovel is a parabolic surface, it below snow shoveling plate the edge of shovel, snow shoveling plate can be around the upset of pipe beam, what control its upset is the crab claw device of a band disk spring, be provided with snow shield on snow shoveling plate, be provided with the shovel board elevating mechanism in the back of snow shoveling plate, elevating mechanism is provided with lifting hydraulic cylinder.The reinforcing rib that a shortcoming of this Salt distributing vehicle for snow removing is the shovel board back is made of the welding of multistage steel plate, has reduced the intensity of reinforcing rib, has increased processing step, has strengthened cost of production.To be shovel board with mainframe connected to constitute by the pipe beam another shortcoming of this Salt distributing vehicle for snow removing keeps away the barrier rotating mechanism, on Guan Liang, be stamped gland, with the screw threads for fastening connector gland is fixedly connected on mainframe, thereby realize that shovel board is fixed on the mainframe by Guan Liang, this complex structure, increase processing step, increased production cost of products; In this external snow pushing operation, the shovel board rotation, resistance is very big, has increased the power output of propelling vehicle motor, has increased energy consumption.It is that the snow cave shovel part is not provided with walking mechanism and stop and release mechanism that this Salt distributing vehicle for snow removing also has a shortcoming, can not on road, walk, before construction operation, need the snow cave shovel of Salt distributing vehicle for snow removing partly to be contained in and transport to the construction operation scene on the load-carrying vehicle and remove the snow with crane, if highway maintenance unit does not have crane, just a dead lift can only be adopted, snow removing can be incured loss through delay like this.
