A, applicable scope
QG - 3 Ⅱ type electric rail rail sawing machine is suitable for cutting *3 ㎏ / m ~ *5 ㎏ / m rail, electric rail rail sawing machine cutting section quality conforms to the railway industry standards. Electric rail rail sawing machine is railway works departments line overhaul, maintenance and repair work necessary tools. Electric rail rail sawing machine it is cutting speed, electric rail rail sawing machine wafer wheel utilization rate is high, the electric rail rail sawing machine cutting section high quality, electric rail rail sawing machine operation is simple, electric rail rail sawing machine is easy to move, electric rail rail sawing machine use safety, electric rail rail sawing machine widely used, etc.

Second, the main technical parameters
1, motor:
1) type: 1 d**0l - 2 (Y**0L - 2)
2) power: 3.0 kW
3) speed: cast aluminum shell ***0 r/min (cast iron shell ***0 r/min)
2, wafer wheel (shaft) :
1) spindle speed of ***0 r/min (***0 r/min)
2) specifications Φ **0 x Φ *2 x 4
3, cutting time *0 kg/m rail, acuities **0 s
4, wafer grinding wheel used times of *0 kg/m or use four *0 kg/m or use three times
5, the quality casting aluminium shell motor acuities *4 kg (cast iron shell motor acuities *4 kg)

Three, the basic structure and working principle
Working principle: according to no tooth saw cutting principle, the use of tilting mechanism, rotate the chip of grinding wheel axis around the rail line along a certain path reciprocating swing, wafer cutting grinding wheel rail. Wafer wheel turning plane and rail profile contact length is lesser, thus reducing wafer grinding wheel wear and improve the sheet wheel utilization rate and working efficiency.
1 and the Lord movement: by the motor, drive v-belt drive make main shaft (wafer wheel) rotary.
2, feed movement: using the cutting arm and oscillating arm relative swing, rely on the dead weight of cut rail machine to realize wafer grinding wheel feed movement of cutting. Cutting arm shaft wafer grinding wheel surface of revolution in the swing arm (card rail agency) center plane flanking, and cantilever is longer, so saw blade can cut to rail bottom.
Structure:
1, oscillating arm shaft, suites for rolling friction, reducing wear and prolong its service life.
2, oscillating arm, cutting arm, pulley for casting aluminum alloy structure, light weight, high strength.
3, the clamping mechanism has a derailment prevention function, cut rail machine in rail, cut rail machine center of gravity and the rail center axis coincidence, even if unscrew clamping screw, cut rail machine does not occur tilt.
4, motor frame system for casting aluminum alloy, reduce weight.
5, travel agency additional auxiliary wheel, guarantee on the ground when carrying out smoothly.
6, motor are divided into TYPE. DIA**0L - TYPE 2 (casting aluminium shell), Y**0L - TYPE 2 (cast iron shell) two kinds, user can choose according to need. The cast aluminum shell motor quality is light.
1 joystick, 2 motor, 3 oscillating arm, 4 spindle wafer wheel, 5 fixture, 6 cutting arm, 7 go road wheel, 8, switch button

Four, method of use
1, in not to install wafer wheel, ON power supply, press the starting button "ON", observe whether wheel spindle rotation and pay attention to the direction of rotation is marked with the shield of the grinding wheel rotation direction. Such as spindle not rotating or rotating direction and protective cover specified wheel rotation direction not consistent, press OFF button "OFF" to cut OFF the power supply, change the power phase sequence, and repeat the process until the grinding wheel spindle rotation, can install wafer grinding wheel.
2, installation sheet wheel before inspection sheet wheel have crack, two side is flat, surface not common cause incision deflection and jaw, install after piece twist lock nut, but torsion shoulds not be too big to avoid crushing wafer grinding wheel.
3, will cut rail machine installed in rail, pull out installed in a fixture on the 5 of the locating rod, the locating rod end indicating position is grinding wheel cutting position, according to the need to move cut rail machine to preset cutting position. Then make fixture interior surface (convex) and the rail top surface, rail palatine bottom of the point, screw tightly fixed bolt, cut rail machine in working state.
4, one hand pull the lever make cut rail machine in rail above, at the same time the other hand support another lever, in case sheet wheel impact rail.
5, installed cut rail machine, press the starting button "ON" can start motor. Motor starting, no-load running time not less than *0 seconds, observation wafer wheel whether smooth operation, whether partial pendulum, beating and each is normal or not, if discovery is unusual, should stop replace grinding wheel or debugging.
6, cutting, wafer grinding wheel feed mainly by cutting rail machine of self-respect and lever of swing, so both hands support joystick, don't downward fierce pressurized, should according to need rhythmic swinging lever.
7, cutting process, hand lever to keep reciprocating swing, do not stop somewhere. When there is a jaw phenomenon, should be slowly lift wafer grinding wheel, and then continue to cut, such as still occur jaw phenomenon, should stop check reason or replacement sheet wheel. To cut, wafer wheel must be in phase with the primary incision perfectly, otherwise, should transform cutting position
8, cutting process, such as incision happen tilt, should stop check reason, debugging or replacement sheet wheel, transform cutting position, to cut.
9, is usually first cut the rail top, then cut the waist, and cut the bottom, until the cut off.
*0, when wafer grinding wheel wear to a certain degree (wheel diameter about less than **0 mm), from the rail side may not cut off the rail, at this time should be placed on the other side of the grinding wheel to cut rail, until the cut off. When grinding wheel wear after less than **0 mm in diam., due to wheel speed is reduced, grinding wheel will accelerate loss, at this time even for cutting rail can also occur cannot be completely cut off, recommend replacing wafer wheel, avoid rail not cut off, and then replace grinding wheel cause new grinding wheel with the original incision doesn't agree with phenomenon.

Five, machine maintenance and maintenance
1, oscillating arm and long axis should be maintained between lubrication, regularly to oil nozzle intra-articular injection of lubricating oil.
2, cut rail machine run up to **0 hours, should remove cleaning spindle bearing, replace the grease.
3, oscillating arm and cutting arm all use thread pin shaft connection, with a factory modulated good, when wear loose form, can loose lock nut, turn the screw thread pin shaft, adjust the unit axial clearance, make its can mutual rotation, and have no axial channeling move so far, and then, locking nut.
4, v-belt tension, with two hex bolt gyration adjusted.
5, in use, transport process should not be put, fall.
6, long time no, should be placed in ventilated, dry, no corrosion gas in the warehouse. Such as moisture or rain, before use ought to use **0 v measurement insulation resistance by megger, electrical device to stand insulation resistance not less than 7 m Ω.
7, before using the power wire, plug and check whether the switch is good, otherwise cannot use. Insert the power socket ago, motor switch should be in the "off" position. Plug, plug must match, and correct ground.
8, don't make the power cord contact heat source, grease. Prevent power cord chafe, cut, rolling bad.
9, wafer grinding wheel should be moistureproof, collision, prevent pressure.
