Application method of gjm-6.0 multifunctional rail finishing mill

1. Preparation before use

1.1 carefully read the operation and maintenance instructions of gasoline engine and this machine.

1.2 add an appropriate amount of mixed oil of gasoline and engine oil in the ratio of 25:1.

1.3 check all parts of the grinder to ensure they are complete, intact and firmly connected.

1.4 check whether the model, material and particle size of the grinding wheel meet the requirements, whether the grinding wheel is warped, deformed, damp or beyond the warranty period, and whether the speed of Z high line meets the requirements (60m / s).

1.5 check whether the grinding wheel is firmly installed, check the wear of the grinding wheel and determine whether it needs to be replaced.

1.6 check the air inlet filter element to determine whether it needs to be replaced.

1.7 after the gasoline engine is started, preheat it for 1 ~ 3 minutes. After the operation is stable, observe whether the engine has abnormal noise and whether the grinding head rotates abnormally.

1.8 check the disease condition, confirm the start and stop position and grinding workload;

2. Grinding operation

2.1 during operation, two people shall lift the grinder onto the steel rail of the turnout to be polished and place it stably.

2.2 move the grinding trolley to the position to be polished, adjust the inclination and height of the grinding head and lock it according to the actual situation.

2.3 calibrate the grinding wheel position based on the steel rail, rotate the transverse running wheel to make the working point of the grinding wheel coincide with the disease position;

2.4 light test grinding Rail: rotate the lifting hand wheel, gently contact with the rail surface, gently push and pull the grinder, mark with the scratch on the rail, and confirm whether the grinder is positioned and aligned;

2.5 raise the grinding wheel to make the distance between the grinding wheel and the rail more than 5mm;

2.6 start the gasoline engine and adjust it to the rated speed. The grinding operation can be carried out only after it runs stably.

2.7 angle adjustment: adjust the angle according to the work demand, and adjust 2 degrees each time.

2.8 according to the grinding position, move the grinder traveling frame and grinding trolley to cooperate with each other to complete the grinding work.

2.9 during the grinding process, the height and inclination of the grinding head shall be adjusted at any time according to the conditions of the grinding position, so as to reach the best Z position and lock it. Then manually move the grinder running frame and grinding trolley to cooperate with each other for grinding operation. The grinding guide part should be coordinated to make the grinding uniform and smooth.

2.10 when the grinding wheel diameter is worn to 30mm thick, it shall be replaced with a new grinding wheel.

3. Safety operation procedures

3.1 when using this machine to grind the turnout, it shall be determined to block the line or use the train interval operation according to the workload of turnout grinding. Both operation modes shall be protected according to the regulations. Do not work blindly.

3.2 the operator must carefully read this manual, understand the main performance indicators, structure and use method of the machine, and strictly abide by the safety operation procedures.

3.3 operators shall wear work clothes, protective glasses, leg guards, gloves, etc. to prevent grinding sparks from hurting people.

3.3 before starting the gasoline engine, check whether the fuel in the oil tank is sufficient. When the engine is working, do not fill gasoline to prevent fire.

3.4 when filling gasoline, do not spill or overflow the oil tank; Once spilled, wipe it still; Smoking or open fire is not allowed nearby.

3.5 when the gasoline engine is hot, carefully open the fuel tank cover to reduce the air pressure in the fuel tank and make the oil have expansion space in the hot oil tank.

3.6 turn off the gasoline engine when changing the grinding place.

3.7 during grinding operation on the line, protection shall be set according to the provisions of "technical regulations" and "safety regulations" to ensure personal and driving safety.

3.8 when a train passes during operation, it is necessary to get off the track and avoid the vehicle. The equipment shall be placed outside the construction clearance and prevent intrusion into the adjacent line.

3.9 during grinding operation, pay attention to the surrounding personnel and equipment at any time to prevent grinding splash from hurting people or equipment.

3.10 if the operator splashes gasoline, he must change his clothes immediately.

3.11 shut down the engine when replacing grinding wheel and repairing machinery.

3.12 replace the grinding wheel, tighten it with a wrench and idle for 30 seconds. Irrelevant personnel shall not approach during the test run.

3.13 always check the fastening nuts of grinding wheel and safety cover.

3.14 do not use grinding wheel whose speed does not meet the requirements of the machine.

3.15 during transportation, the remaining fuel in the oil tank shall be drained.

3.16 during shutdown, the throttle shall be adjusted down first to reduce the speed, and then the gasoline engine shall be shut down after no-load operation for several seconds.

4. Next operation

4.1 before getting off the road, turn off the engine.

4.2 return the grinding head of the grinding wheel to the normal position, rotate the lifting hand wheel to raise the grinding wheel to the high point of Z, then adjust the angle turntable and rotate the transverse traveling runner to retract the trolley back to the middle of the machine.

4.3 two operators lift the grinder out of the line.

4.4 after getting off the track, place the grinder in a safe position that does not invade the "construction clearance".

4.5 before finishing work, the grinder shall be fully maintained and wiped, the machine sleeve shall be covered, and the machine shall be bound firmly.

4.6 when the grinder is not used for a long time, it must be placed in the warehouse to prevent moisture or rain.
