Problems solved by technology
When the rail locomotive wheel is idling, the sticking block is attached to the rail locomotive wheel by contacting the tackifying block with the rail locomotive wheel, increasing the friction coefficient between the rail locomotive wheel and the track, and solving the problem of rail locomotive wheel idling. Completely replaced the original sand removal device, no need for post-track slag cleaning operations to reduce slag cleaning costs, with very little residue, and solid residues can be taken away by the wind of the locomotive, without any damage to the track

The invention relates to the technical field of safe operation of rail locomotives, and specifically relates to a friction machine and a control system for a locomotive wheel tackifying block. The tackifying block is composed of an adhesive material and an adhesion coefficient improver. The friction machine includes a feeding driver, a driver fixing flange, a rear baffle, a feeder fixing slide rail, a feeding box and a thickening block. The feeding box is slidably connected to the feeder fixing slide rail, and the thickening block is slidingly connected to the feeding box. Inside, a drive shaft is connected between the driver fixing flange and the rear baffle, and the drive shaft is connected with a feeding driver. Extend the feed box. The lower end of the fixed slide rail is rotatably connected with a feeder close to the separation cylinder. The invention has a high degree of automation and completely replaces the original sand removal device. There is no need for later track slag cleaning operations, and there are few residues, which can be taken away by the wind of the locomotive. No damage to the track.
Description
technical field [0001] The invention relates to the technical field of safe operation of rail locomotives, in particular to a friction machine and a control system for a locomotive wheel viscosity increasing block. Background technique [0002] When the train starts and runs on a slope with a slope of ≥10‰ or a large curved path or tunnel, the adhesion coefficient between the locomotive wheel and the rail will decrease, and the traction wheel-rail adhesion coefficient of the locomotive will decrease by 20-30% in the weather of rain, snow, fog and frost , the coefficient of adhesion will decrease by 50% when the rail is polluted. With the advancement of traction technology and the improvement of locomotive manufacturing level, the power of locomotives continues to increase, and the adhesion between wheel and rail can no longer meet the normal requirements for the traction of high-power locomotives. Adhesion has become a key factor limiting the improvement of locomotive tract...
