Technical Field

The invention relates to the technical field of snow sweeping equipment, in particular to a rolling brush device for removing snow on a track and an operation method thereof.

Background

In northern and plateau cold areas, snow falls in winter can be accumulated on railway lines, when the snow falls in large quantity, snow covers railway rails even, the railway rails are difficult to maintain and overhaul, the line condition is unclear, potential safety hazards exist, and the train operation safety is seriously affected, so that timely clearing of the snow on the lines is very important in the railway line maintenance process.

The accumulated snow on the track line is cleared by two modes of manual snow shoveling and mechanical cleaning. The manual snow shoveling method needs more personnel, has large labor amount and high labor intensity, takes longer cleaning time and has poor working environment conditions, and in addition, the passing density of a train is higher, and the safety of constructors is difficult to ensure; besides rail sleepers, spikes and steel rails, various line equipment such as a capacitor box and a signal line are arranged on a railway line, the actual situation is very complex, snow removal operation is required on the premise of meeting the running conditions of the railway line, and the line equipment cannot be damaged by the snow removal operation, so that the mechanical snow removal device is complex in requirement, extremely high in difficulty and less in mature mechanical equipment.

At present, foreign railways widely adopt a mode of mounting a propeller snow winching machine or a rotary cutting type snow throwing machine on a railway locomotive, and are only used for cleaning deeper snow on the surface of a steel rail so as to ensure that a train can normally pass through. The method needs to install a propeller snow winching machine or a rotary cutting type snow throwing machine right in front of the train to influence the normal coupling of the train, and in order to ensure the safety under the condition of high driving density, the technical standard of the railway industry in China does not allow, the method cannot be adopted for removing snow, and the railway in China still mainly adopts a mode of manually shoveling snow at present.

In China, some airports and roads adopt rolling brushes to sweep snow, but because the airports and the roads are relatively flat, strict requirements on running tracks of vehicles are not required, and the requirement on snow sweeping speed is not high. Compared with the snow sweeping rolling brush devices used in the industries, the rolling brush devices adopted by the track snow sweeper have obvious differences in connection mode, structure, principle, operation effect and the like.

At present, no rolling brush device for snow sweeping operation of railway lines is available at home and abroad, only partial airports and roads adopt rolling brushes to sweep snow, and the existing rolling brush device mainly has the following characteristics:

1) the snow sweeping device has different application fields and low requirements on use environment, is mainly used for snow sweeping equipment such as airports, highways and the like, and is mainly used for sweeping the snow on a flat road surface, so that the road surface condition is simple, and the operation has no other special requirements;

2) the rolling brush device is usually arranged at the front end of the snow sweeping equipment, the height of the rolling brush is not required to be adjusted or is not frequently adjusted in the snow sweeping process, and the structure of the mounting and fixing device is simple;

3) in order to enhance the cleaning force and the wear resistance, the brush filaments of the rolling brush are usually made of steel brush filaments, or the steel brush filaments are mixed with plastic and nylon;

4) the roller of the rolling brush is usually an isometric round roller, so that the structure is simple and the installation is convenient;

5) the installation is hardly limited by space, and the width of the rolling brush device can be set according to the snow sweeping operation range;

6) only one working direction is available, namely, snow sweeping can be carried out only forwards (the rolling brush device is arranged in front);

7) the snow sweeping operation speed is generally lower, and the installed power is lower.

Railway equipment is limited by line operating conditions, and installation space, use requirements and the like of the railway equipment are greatly different.

For example, the patent of the Chinese utility model with the publication number of CN 203639872U discloses a snow sweeping rolling brush, which comprises a brush holder and a rolling brush, wherein two ends of the rolling brush are in transmission connection with the brush holder through a motor holder; the motor is arranged in the motor frame, the middle position of the brush frame is connected with a rotatable revolving frame, and the brush frame is connected with the revolving frame through a shaft. One side of the revolving frame is hinged with a connecting frame through a first connecting rod and a second connecting rod, an oil cylinder is installed on the brush frame, a piston rod of the oil cylinder is connected with the revolving frame, the brush frame can swing within a certain range under the action of the oil cylinder, the quick connection design is adopted, the installation and the disassembly are quick and convenient, the brush frame can be installed on various automobile chassis and engineering loaders, and the utilization rate, the interchangeability and the operation response speed of equipment are fully improved. The supporting wheel is removed, so that the device is more concise and efficient, the maintenance work of the supporting wheel is removed, and the stability of the product is improved. However, the snow sweeping roller brush can only be applied to the occasions where the road surface is flat, such as highways, airports and the like, can only work towards one direction, and has high installation requirements.

For example, the chinese patent with publication number CN 104111660B discloses a snow sweeper, and a device and a method for controlling the lifting of a rolling brush of the snow sweeper. This round brush lifting control device includes: the controller calculates an actual height value according to data detected by the first sensor and the second sensor, compares the actual height value with a preset height set value, runs a PID control algorithm, and controls the rolling brush to ascend and descend to the set height according to a calculation result. The roller brush lifting control device and method of the snow sweeper can keep the ground clearance of the snow sweeper stable, enables operators not to need to manually operate outside a driving cab in cold weather, and improves the operation comfort of the workers. However, the invention can only be applied to the occasions where the road surface is flat, such as a highway, an airport and the like, can only work towards one direction, and can be installed at the end of a road vehicle, so that the space limitation is small.
