Track Way Rail Waist Surface Grinding Machine
Track Way Rail Waist Surface Grinding Machine is applicable for grinding works before railway laying, subway maintenance welding and gluing insulated joints construction. This work is one of the heavy workload jobs in the rail welding operation. In the past, it was mainly carried out by hand-held electric grinder or angle grinder, it has led to high labor intensity, low operation efficiency and slow working speed, poor grinding surface quality, serious environmental pollution etc. The rail waist grinding machine is suitable for 50kg/m-75kg/m rails.
- Product Introduction
NGYM-4 Track Way Rail Waist Surface Grinding Machine is applicable for grinding works before railway laying, subway maintenance welding and gluing insulated joints construction. This work is one of the heavy workload jobs in the rail welding operation. In the past, it was mainly carried out by hand-held electric grinder or angle grinder, it has led to high labor intensity, low operation efficiency and slow working speed, poor grinding surface quality, serious environmental pollution etc. The rail waist grinding machine is suitable for 50kg/m-75kg/m rails.
Basic Structure and Working Principle
Working Principle:
The four-stroke petrol engine is used as the power source, the belt pulley is driven to rotate through the clutch, the main shaft is driven to rotate through the belt, and the rail waist is polished through the flexible shaft connected with the grinding wheel.
Basic Structure:
1 Operating handle, 2 Petrol engine, 3 Clutch reducer, 4 Connecting rod, 5 Grinding wheel, 6 Grinding wheel cover, 7 Clamping device 8 Ejector rod of clamping device
Operation:
1. Read the Manual of machine and petrol engine in details before operation.
2. Be sure to add enough engine oil and fuel as required before operation.
3. Check whether the grinding wheel and each part are fastened.
4. Place the clamping device on the rail, adjust and fix it, and lock it with its ejector rod.
5. Connect the connecting rod of the machine with the vertical rod of the clamping device to determine whether the rail waist and grinding wheel are in a straight line, which can be adjusted by gasket.
6. Start the petrol engine according to the instructions of the engine.
7. Hold the handle and move the throttle lever toward the Max. position. (Throttle usage: in winter or when it is difficult to start, press the throttle to the bottom directly and close the air outlet of the damper, lift the throttle up to the position where it collides with the damper baffle after the petrol engine is started. If it is necessary to turn off the petrol engine, just lift the throttle up.) Approach the grinding wheel to the rail waist slowly when grinding, and move it back and forth to grind the rail waist.
8. During grinding operation, pay attention to fit the grinding wheel with rail waist slowly, Check whether the joint surface of grinding wheel is fitting closely to rail waist. In case of deviation, adjust the fixture left and right.
9. When grinding the glued fishplate joint, it is necessary to move the clamping device back and forth to achieve the required grinding length.
10. Turn off the petrol engine after operation, then fold the handle to the front, Take the machine and clamping device out of the railway boundary limit.
