Description

High-speed rail ballastless track rail grinding iron filings collection device

technical field

The utility model relates to iron scrap collection equipment, in particular to a high-speed iron ballastless track rail grinding iron scrap collection device.

Background technique

As we all know, high-speed railway has gradually become the most convenient and efficient means of transportation due to its advantages of large transportation capacity, fast speed, good safety, little impact from climate change, high punctuality rate, comfort and convenience, low energy consumption, and small environmental impact. It puts forward higher requirements for the safety of high-speed railway operation, and high-speed railway maintenance is an important part of ensuring safety.

The ballastless track rails of high-speed railways are repeatedly rolled by rollers, and countless small cracks will appear on the rolling surface of the rails. If they are not ground in time, the small cracks will continue to extend, and the stress will concentrate at the extended cracks, eventually causing the rails to break and cause traffic accidents. . Today, grinding the rails is the only solution available. However, the iron filings and dust generated by grinding rails and the high-temperature sintered lumps also threaten the safe operation of high-speed railways and pollute the environment.

The current conventional method is manual cleaning, but manual cleaning is not only labor-intensive and inefficient, but also has no safety guarantee, and it is easy to cause secondary dust. In order to solve the aforementioned problems, various iron scrap collecting devices have been designed, which mainly include electromagnet dust-absorbing trolleys and powered industrial vacuum cleaner trolleys. Among them, the use of the electromagnet dust-absorbing trolley will endanger the electrical safety of the track. During the dust-absorbing process, the track may be magnetized, and iron filings will be absorbed by the track, which will cause serious safety hazards; while the powered industrial vacuum cleaner has low cleaning efficiency and rail gaps It is difficult to clean and cannot absorb bulky objects such as sintered lumps. Therefore, it is urgent to provide a high-speed rail ballastless track rail grinding scrap collection device to overcome the above-mentioned defects.

Compared with the prior art, the utility model of the high-speed rail ballastless track rail grinding scrap collection device sucks air through the negative pressure machine and blows air through the blower, thereby forming a strong local cyclone above the track bed to remove all dust and All lumps are collected into the dust collection box through the suction port of the negative pressure machine, so as to achieve the purpose of cleaning iron dust and lumps, and the cleaning is very thorough at one time. In addition, the device has a compact structure and is easy to operate, and only one operator is required to complete the collection. The operation efficiency is high and the use and maintenance costs are very low.

Preferably, the suction port of the negative pressure machine is set directly above the horizontal line of the end surface of the track bed, and the cleaning is more thorough.

Preferably, there are at least two sets of blowing mechanisms, the air outlets of the blowing mechanisms form an angle with the horizontal line of the end surface of the ballast bed under the track and face the suction port. Setting multiple sets of blowing mechanisms can increase the cyclone range of the track bed and improve cleaning. efficiency.

Preferably, the tuyere is arranged symmetrically on both sides of the suction port of the negative pressure machine, so that the distance from the ballast bed can be reduced and iron filings and dust can be blown to the middle of the track bed from both sides to increase the cyclone intensity , It is easier for the negative pressure machine to suck it into the dust box, further improving the cleaning efficiency.

Preferably, one end of the frame is provided with a connecting mechanism for connecting with power equipment. The connecting mechanism connects the frame to the power equipment, which can realize the on-line collection of iron filings after rail grinding. The entire process can be automatically controlled to further save labor.
