Snow removal truck used in airport

Abstract

The invention relates to surface equipment used in an airport, in particular to a snow removal truck used in an airport, which comprises a chassis, a suspension gear and a snow shovel, a snow removal roller brush device and a snow blowing device, wherein the upper part of the chassis is provided with a power transmission device and a hydraulic system, the lower part thereof is provided with a high-position transfer case, and the whole truck is provided with a night-viewing monitor; the snow removal truck is characterized in that the lower part of the high-position transfer case is provided with the snow removal roller brush device which is fixedly connected with the chassis by a fixed support, thus leading the snow removal truck to form a snow removal mode of pushing by the front, removing by the middle part, and blowing by the rear part. As the structure is adopted, the snow removal truck has the advantages of novel structure, high work efficiency, high removal rate, small residual snow amount and the like.

Description

technical field [0001] The invention relates to airport ground equipment, in particular to an airport snow removal vehicle for removing snow from airport runways. Background technique [0002] As we all know, the northern airports use snow removal vehicles to clear the runway snow in winter to ensure the friction coefficient of the airworthiness of the runway. The snow removal capacity of the airport is directly related to the safety of aircraft takeoff and landing in snowy weather and whether the airport is closed or not. [0003] At present, the snow removal equipment used at the airport mainly includes single-function vehicles such as snow pushers, snow plows, and deicing and spreading vehicles, as well as multifunctional snow removing vehicles that combine the functions of snow pushing, snow removal, and deicing and spreading. The car-type snow removal vehicle is refitted from a car chassis, usually with a suspension device and a snow shovel at the front of the car chass...

AI Technical Summary

Problems solved by technology

The car-type snow removal vehicle is refitted from a car chassis, usually with a suspension device and a snow shovel at the front of the car chassis, with rut cleaning disc brushes at the front of the front wheels of the car chassis, and a snow-sweeping brush at the rear of the car chassis through fixed supports. Rolling brush device, the rear end of the car chassis is fixedly supported and the snow-plowing roller brush device is equipped with a snow blowing device, the upper part of the car chassis is equipped with a power transmission device and a hydraulic system, and the snow-plowing roller brush device includes a swing cylinder, a rotating bracket, a fixed arm, a lifting Oil cylinder, hydraulic motor, roller shaft, rolling brush, rolling brush cover and guard plate, its deficiency is: because the engine on the automobile chassis is directly connected with drive axle, and drive axle drives wheel to realize walking function through drive shaft, makes middle part suffer Due to the influence of the transmission shaft, it is difficult to arrange snow plowing equipment. The snow plowing equipment is mainly arranged at the rear of the car, resulting in limited selection of equipment types and low snow removal efficiency. Moreover, there is residual snow with a thickness of more than 1cm after the snow pusher pushes the snow. Usually, snow plowing equipment is used. After snow removal, there will still be a small amount of residual snow. For the airport, it needs to be processed to meet the friction coefficient requirements.

The ideal snow removal method is: front push + middle sweep + rear blow snow sweeping mode, but it is difficult to arrange snow sweeping roller brushes in the middle of the car chassis due to the influence of the drive shaft. The snow sweeping roller brushes are mainly arranged at the rear of the car, and the snow sweeping roller brushes Difficult to arrange other machines in the back

In addition, the gap between the snow-sweeping roller brush and the cover increases with the wear of the brush seedlings, and the sticky snow of the roller brush becomes a snow stick, which increases the amount of residual snow. Usually, separate snow melting or snow blowing methods are used for multiple treatments, which increases the cost of snow removal and working hours
