Description
Technical Field
The invention belongs to the technical field of snow shoveling, and particularly relates to a snow shovel for an airport.
Background
The snow fall volume in winter in the north is many, because the weather is cold, snow can not melt for tens of days even months, especially road snow brings a great deal of inconvenience and puzzlement for traffic and people's trip, work, life, serious still can cause the potential safety hazard, the aviation industry is the trade that is greatly influenced by snow fall, no matter military aviation or civilian aviation, all need have corresponding infrastructure to guarantee its normal navigation, these infrastructures not only include navigation control system, airport's channel building, signal lighting facilities, facilities such as maintenance, still include various ground foundation guarantee facilities. The snow shovel is used as an important device for removing snow in winter, and becomes an important component of ground infrastructure of the aviation industry. The snow cover in the airport has great influence on the normal operation of the flight, so the snow cover in the airport is very important to process.
At present, the main snow removing modes in China include snow melting and removing, manual snow removing and mechanical snow removing. Each snow removing mode has certain advantages and limitations, the snow removing mode is suitable for the situation of entering winter, and the snow removing operation effect on the road surface which is easy to melt snow is obvious due to high temperature and large snow amount in the beginning of spring, but the method has the defect of certain pollution to the environment and the road. The method for melting snow and removing snow can bring erosion to the runway to a certain extent due to very high requirements on the pavement of the runway of the airport, so the method is not suitable for removing snow in the airport; the manual snow removal is suitable for places with relatively small snow accumulation, although the manual snow removal can thoroughly remove accumulated snow, the manual snow removal has high cost and low efficiency, influences traffic passing order, driving safety and the like, and the snow removal efficiency of the manual snow removal is far not up to the requirement of the snow removal efficiency of an airport, so that the manual snow removal is not suitable for the snow removal of the airport; the mechanical snow removal is suitable for places with large snow accumulation, can carry out large-area mechanical clearing operation, can carry out all-day operation, has the remarkable advantages of real-time high efficiency, economy and environmental protection, basically no influence on traffic, relatively thorough clearing of snow on road areas and the like by using a mechanical method to clear snow on the road surface, but has no large-scale popularization and use due to the reasons of low operation speed, low complete machine utilization rate, poor avoidance function and the like. Our current snow pushing device width is narrower, when clearing up the snow of open sections such as on the road of contrast broad or airport, because the problem of angle, the actual snow pushing width still can greatly discount, and snow pushing shovel's width utilization ratio is very low, sometimes still can appear the phenomenon that snow flows from snow pushing shovel both sides, great reduction work efficiency. Therefore, the invention of the efficient snow removing device suitable for removing snow in the airport is particularly important.
