Belt running speed, roller and more, a little careless, often easy to cause injury accident. To prevent injury accident should take the following measures:
1. Transmission part of the belt conveyor nose, tail drum, fluid couplings, etc. must be installed or protective guard railing. Need to cross the bridge should be installed in
the conveyor channel ladder, roller chain conveyor roadway lighting is sufficient.
2. The driver before driving; want to check on the conveyor belt and near the nose and tail, no one really observed only after the issue driving signal. Starts, the first jog
test, indeed no problem to have a formal driving.
3. Driver's clothing should be agile, cuffs, Kujiao, skirts to truss, long hair must be inside the helmet plate. Operation, the roller oiling or be particularly careful when
handling failure, non-direct hand to fiddle with rollers.
4. Conveyor running them, Gravity roller conveyor is strictly prohibited shovels or other tools scrape sticky slime on the drum, or reversal of positive deviation tool belt, otherwise, the most prone
to injury accident.
5. Conveyor ride strictly prohibited. Conveyor stops running, if not cut off the power and put up "Someone working to prohibit driving," the warning signs, prohibition overhaul,
nor stay in the conveyor belt.
6. Roadway conveyor mounted on both sides must be of sufficient width, the conveyor from the stanchions or arch wall distance not less than 0.5 meters, pedestrian side not less
than 0.8 m.
7. To prevent fires, you must use fire-retardant conveyor belt, hydraulic coupling medium must use non-flammable media and require the installation of smoke, temperature
protection device and automatic sprinklers.
8. To ensure the quality of the conveyor installation, the driver should strengthen the maintenance and inspection conveyor, abide by the rules.

the water spray, continuous 90 degree turn conveyor operation 72h, when the water shall not exceed 150g;
b. waterproof roller (finger contact type seal) in the flooded working conditions, continuous operation shall not exceed the amount of water 24h backward 5g.
7. Roller (not including buffer roller) in the design of a reasonable choice, speed is lower than 550r/min case, life is not less than 20000h, the failure rate is less than 12%.
b. roller axial displacement shall not exceed 1.5mm.

The role of belt conveyor drive roller and type
The drive pulley belt drive device is powered by the frictional force transmitted to the conveyor member . Typically, the drive roller with steel plate welded structure and
welding structure forms.
Welded steel roller shaft and flexible conveyor the hub connection between the use of bond can withstand small loads ; cast welding roller shaft and the hub connection between the use of
expansion sets . Avoid the linkage shaft strength weakened , so this structure in the form of cylinders can withstand a greater load , and easy installation and removal. Drum
surface and Telescopic belt conveyor smooth plastic surface in two forms, adhesive side effect is to increase the drive roller and the friction between the belt . Plastic drum with rubber surface and
coated cast two process types , casting plastic rollers and wear thick rubber surface , good quality, but the process is complicated high price ; package plastic drum process is
simple and low cost. Plastic surface drum light adhesive surface, herringbone and diamond-shaped trench trenches three types . When using the herringbone grooved rubber surface
roller , should pay attention to its direction. Herringbone tip should be facing the direction of rotation of the drum , diamond plastic surface for bidirectional transport
roller conveyors . For important occasions preferably vulcanized rubber roller cladding . When there is fire , explosion conditions require , should adopt appropriate measures.

Belt driven structure
Conveyor motor through the coupling , gear drive or other drive roller rotation drive mechanism , the drive mechanism by means of rollers or other friction between the belt ,
the belt movement. Hunger drive belt roller conveyor conveyor drive unit by way of drive mode can be divided into single-point and multi-point drive two kinds .
TD75 general fixed belt conveyor drive more than a single point , namely the installation of centralized drive the length of the conveyor at a certain position , usually on
the head office .Power Roller Conveyor Single-point drive by the number of drive roller can be divided into single drum and double drum drive . For each drum drive can be divided into single- and
multi- electric motor drive right drive . Due to a single motor drive mode most commonly , those who did not specify multi-motor drive, it is a single drive , it is generally
driven approach for single-point call , "single point" word is often omitted .

Belt conveyor drive unit
Driving means is the driving force of the belt conveyor , which consists of motor, reducer , chain conveyor coupling, drive roller components. Driven by a drum or two motors through their
coupling, reducer, and chain couplings transmit torque to the drive roller.
Reducer with two , three and multi- stage gear reducer , the first level of straight bevel gear drive, second , three to slow down and drive helical gears , connecting the
motor and Check weigher reducer couplings have two, one flexible coupling , one is hydraulic couplings. To this end, a bevel gear reducer , there are two ; elastic couplings , with the first
bevel gear , shaft head for the flat key connection ; with hydraulic coupler, with a second bevel gear , shaft head for the splined gear coupling .
Drive pulley welded structure , main bearings aligning bearings, drive roller rack with motor, reducer racks are installed in large fixed above the base , the motor can be
mounted on either side of the nose .
