Abstract

The invention provides a method and a device for tackifying a rail train and a wheel rail. By the method and the device, tackifying of the wheel rail under a clean dry state can be realized, tackifying effect is good, and control is simpler and easier to implement. The tackifying method includes: 11), setting a jetting and sweeping device capable of generating jetting air and sweeping the wheel rail; 12), heating gas forming the jetting air in the jetting and sweeping device to a preset temperature; and 13), enabling the jetting and sweeping device to move along with the rail train and sweep a rail face and a contact area of the wheel tail and the wheel rail at a preset air speed. The tackifying device comprises the jetting and sweeping device capable of jetting air and sweeping and a heater for heating the gas forming the jetting air in the jetting and sweeping device to the preset temperature, and an air jetting position of the jetting and sweeping device is arranged correspondingly to the contact area and the rail face. By the method and the device for tackifying the rail train and the wheel rail, the contact area of the wheel rail and the rail face can be swept through air energy, good contact adhesiveness of the wheel rail can be guaranteed to enable the wheel rail to normally run, and control of the device is simpler and easier to implement.

Description

technical field [0001] The invention relates to the technical field of rail transportation, in particular to a method for increasing the adhesion between wheels and rails. The present invention also relates to a thickening device using the above method. The present invention also relates to a rail train comprising the above-mentioned thickening device. Background technique [0002] In the field of rail transportation technology, the adhesion state between the wheel and rail plays a crucial role in its operation. Since oil stains, water stains, dust and other sundries are easily accumulated between the wheels and rails, when the adhesion between the wheels and rails is small, slipping and other phenomena may occur, which may lead to safety accidents. Therefore, it is necessary to increase the viscosity between the wheel and rail to improve the friction between the two and ensure the smooth and safe operation of the train.

Problems solved by technology

[0007] In summary, in the control of the use of fillers, it is difficult to achieve a good adhesion effect with a rough control mode, and even if there is a mathematical model that can effectively simulate the use of fillers, the implementation process is quite complicated; and The control process of incoming material quality is relatively cumbersome, and requires high precision in operation, so it is difficult to achieve effective control

[0008] It can be seen that how to effectively control fillers is a technical problem in this field. If this problem cannot be solved, it will lead to many potential safety hazards

[0009] In addition, the filler is filled between the wheel rails and mixed with water stains, oil stains, powder stains and other sundries between the wheel rails, so it is difficult to achieve the adhesion of the wheel rails in a clean and dry state

[0010] Therefore, the existing control strategy of the filler method can no longer meet the thickening requirements of the wheel and rail. How to design a thickening method and device for the wheel and rail to improve the thickening effect and effectively control the thickening state is an important issue. Technical problems that technical personnel in the field need to solve at present
