Description

A new type of railway track bed cleaning vehicle

technical field

The invention relates to a device for cleaning and dusting the surface of a railway track bed, which is used for cleaning and collecting various dirt on the surface of the track bed, and belongs to the technical field of railway maintenance machinery.

Background technique

At present, the dirt on the surface of the track bed mainly includes the following categories:

a. Small particle waste such as stones and sand produced by construction before the opening of the ballastless track;

b. Grinding iron chips generated when the rail is regularly polished after the ballastless track is opened;

c. Sand collection on the surface of ballasted and ballastless track beds in desert areas;

d. Coal particles dropped when coal trucks are running on special coal transportation lines, especially when passing through tunnels;

e. Some wastes discarded by passengers.

The above-mentioned dirt remains on the surface of the railway track bed, which not only affects the environment along the railway, but also affects the safe operation of the railway vehicles. For example, on the ballastless passenger dedicated line, due to the high speed of the vehicles, the dirt such as gravel and sand accumulated on the surface of the ballast bed may damage the sensors or other electronic devices at the bottom of the vehicle after being picked up by the high-speed vehicles, resulting in vehicle failure or even damage Accidents; for the coal transportation line, the scattered coal powder rolled up when the train passes will affect the driver's sight, especially when the coal powder and coal lumps are deposited thickly, the rails will be buried, and long-term accumulation will also cause the ballast bed to harden. endanger the safety of the train.

The dirt cleaning work on the surface of the railway track bed has been mainly done manually for many years. For example, after the rail grinding vehicle grinds the rails, about 30 people are needed to clean up the grinding dust generated each time; During the period of intensive maintenance and construction, all the long tunnels have cleaning construction teams working at the same time, which takes up a lot of maintenance time, and the dust pollution on site is serious, the working environment is harsh, and the labor intensity is high.

At present, a variety of cleaning equipment has been developed for different passenger lines in China, but there are two problems: one is that these equipment mostly use the combination of sweeping and suction or blowing and suction, and the actual application effect is not ideal; the other is that the existing equipment Only for a single type of dirt, but not for a variety of different kinds of dirt, which reduces the versatility of equipment use, increases the difficulty of use and purchase costs for users, for example, the tunnel coal suction truck is dedicated to the collection of tunnel coal powder 1. The ballast bed desanding vehicle can only deal with the accumulated sand on the surface of the ballast bed. Therefore, a new type of railway track bed cleaning vehicle is designed to solve the above problems through the cleaning method combined with blowing and suction, and has the following advantages: First, it can reduce the labor intensity, greatly reduce the number of operators, and only need to be equipped with a small number of operators; The second is to greatly improve the operating efficiency and shorten the cleaning time; the third is to expand the scope of application and reduce the difficulty of use and equipment costs for users.
