Description
Technical Field
The invention relates to the technical field of safe operation of rail locomotives, in particular to a locomotive wheel adhesion increasing block matching friction resistance machine and a control system thereof.
Background
When a train is started and operated on a slope with the gradient not less than 10 per mill or a large curve path or a tunnel, the adhesion coefficient between a locomotive driving wheel and a steel rail is reduced, the adhesion coefficient of a locomotive traction wheel rail is reduced by 20-30% in rainy, snowy and frosty weather, and the adhesion coefficient is reduced by 50% when the steel rail is polluted. With the progress of traction technology and the improvement of the manufacturing level of locomotives, the power of the locomotives is continuously increased, and the adhesive force between wheel rails can not meet the normal requirement of the high-power locomotives for exerting the traction force. The sticking problem has become a key factor limiting the increase in locomotive traction brake force. In fact, the development of rail traction technology has led to the full use of adhesion between the rails of a locomotive wheel and rail being one of the objectives of railroad technologists.
The sanding can recover the adhesion coefficient to about 0.225, the method is a method for solving the idling of the locomotive which is used until now since the birth of the railway, and the defects are more and more prominent along with the improvement of the traction technology and the improvement of the manufacturing level of the locomotive. The sanding defect between the wheel rails is mainly shown as follows: firstly, although the sanding meets the requirement of increasing the adhesive force between the wheel rails, the sand foam on the steel rail increases the resistance to the rolling of the wheels behind the locomotive driving wheel, namely the sanding and the viscosity increasing are at the expense of partial traction of the locomotive. Secondly, the sand between the wheel and the rail accelerates the abrasion, scratch and wave abrasion of the wheel and the rail, and the rail is seriously damaged. Thirdly, facilities built for sanding the locomotive and the consumption of sand materials are huge, and the railway construction and operation cost is greatly increased.
The sanding system of the prior art has the following disadvantages:
1. a large amount of frequent sanding not only pollutes the environment, but also influences the transmission of track electric signals;
2. a large amount of frequent sanding increases the resistance of the train behind, increases the running noise, and is also unfavorable for the rolling bearings of the wheels;
3. in order to achieve the desired effect, sand with good quality, uniform particle size, moderate composition and hardness, and suitable moisture must be selected. The treatment process of the sandstone is various, the price rises year by year, and the economic pressure is increased;
4. when the idling occurs, the sanding only aggravates the abrasion of the wheel, and the sanding can be performed on the steel rail only after the traction force is reduced, so that the full utilization and the exertion of the traction force are seriously influenced;
5. the sanding has poor use effect in high-speed driving because the sand cannot be successfully sprinkled among wheel tracks due to certain air flow in the running process of a train; less than 1/10 of the total amount of sand that can enter the wheel track to play a role. The sanding effect is poor under the conditions of frozen ice, accumulated snow, heavy oil dirt pollution and the like on the rail surface;
6. in the process of sanding, sand entering the surface of the steel rail to play a role is little, most of the sand is accumulated on two sides of the steel rail and needs to be cleaned in time, and the cost for treating roadbed pollution caused by sanding is high;
7. the treatment of sand, such as sand drying, screen cleaning, recovery and storage and locomotive sanding, requires a large amount of manpower and material resources;
8. a large amount of frequent sanding accelerates the abrasion of the wheel rail and reduces the period of wheel replacement and rail replacement.
With the increase of new technologies and new materials at home and abroad, the idling solving mode of the locomotive which is continuously used for a long time is broken through, and the research on the new friction technology and the mode for replacing the traditional sanding is imperative.

1. the effect of water and oil media on the wheel rail sticking coefficient is shown in fig. 8. The adhesion coefficient is relatively small when the wheel rail sample is in a running-in period in the initial running stage, the contact area of the wheel rail is increased along with the increase of time, the adhesion coefficient is gradually increased, and finally the wheel rail sample tends to be stable. The adhesion coefficient of the wheel rail is maximum in a dry state, and the maximum value reaches about 0.69. Compared with the dry state, the adhesion coefficient is obviously reduced under the water medium, about 0.32, and the adhesion is reduced by 53% compared with the dry state.

3. Under the condition of an aqueous medium, the adhesion coefficient is increased from 0.32 to about 0.36 by contacting the adhesion-promoting block on the surface of the wheel under the pressure of 50N, and is increased by about 12.5%. Under the oil working condition, the tackifying effect of the tackifying block is obvious, the adhesion coefficient is increased to 0.32, and the adhesion coefficient is improved by 190%. When the experiment starts, leaves are continuously added to the contact surface, leaf fall pulp is formed on the contact surface of the wheel rail after the experiment is carried out for 15min, the tackifying block is always pressed on the surface of the wheel in the experiment process, so that the surface leaf fall pulp can be removed by the tackifying block, and the roughness of the wheel rail is increased by particles generated by friction of the tackifying block, so that the adhesion coefficient is obviously increased to about 0.107 and is increased by about 8%.
