１ start and stop the conveyor shall generally be under the condition of no-load startup. When progressive installing thousands of belt conveyor, can block starting device should be adopted, so that through the ecr according to certain sequence starting and stopping. In addition, in order to prevent sudden accidents, should also be set on each conveyor start or stop button, you can stop any one alone. In order to prevent the conveyor belt was longitudinal tear due to some reason, and when the conveyor length is more than 30 m, along the conveyor length, should be a distance between (e.g., 25-30 m) to install a stop button.
　　2 and maintenance to ensure belt conveyor belt conveyor operation reliable, the main is the timely discovery and eliminate the possibility of failure. For this operation personnel must observe the conditions of transport work, if discovery is unusual should be processed in a timely manner. Mechanical workers should be regularly patrol and check any situation or components need to be aware of, this is very important. Such as a roller, it doesn't appear very important, but the high speed conveyor belt transmission materials wear may soon casing wear out of it, a blade, the blade may seriously damage a pricey conveyor belt.Workers trained or experienced personnel can timely found the accident, and to nip in the bud. Conveyor belt of the belt conveyor in the entire conveyor cost accounts for a considerable proportion of. In order to reduce the cost of replacement and repair of conveyor belt, must pay attention to in operating and maintenance personnel for conveyor belt running and maintenance knowledge training. Table l - 40 listed a lot of questions about conveyor belt in operating the cause and the treatment method. Belt conveyor failure causes and elimination methods
　　３ the installation of belt conveyor belt conveyor is generally in the following several stages.
　　1) installation of belt conveyor frame rack installation is initiated from the frame, then install the progressive section of the middle frame, and finally furnish tail stock. Before installing the frame first, pull on to the conveyor length of the center line, for keep the conveyor centerline in line is the important condition of conveyor belt running normally, so when installing a section each rack, must aim at the centerline, leveling, and which rack to the centerline of the permissible error, captain per meter is + / - 0.1 mm. But on the conveyor length error not exceeding 35 mm to the center of the frame. When all single section setting and alignment, can connect every single day.
　　2) driving gear drives, must pay attention to make the belt conveyor drive shaft and the vertical center line of belt conveyor, make the middle of the width of the driving drum and belt conveyor of the center line, parallel to the axis of the gear reducer and transmission axis. At the same time, all should be leveling shaft and roller. Axis horizontal error, according to the conveyor width, allowed in the range of 0.5 1.5 mm. While installing device drivers, can install tail wheel tension device, tension device of drum axis, should be perpendicular to the center line of belt conveyor.
　　3) install the rollers in the frame, transmission device and tensioning device is installed, can be installed up and down roller roller frame, make the conveyor belt has a slow to curved, ways of roller spacing is normal roller spacing 1/2 ~ 1/3. Rollers after installation, should make its rotary flexible light.
　　4) at the end of the belt conveyor for in order to ensure the conveyor belt is always at the center of the roller and roller line operation, when installing rollers, rack and the drum,
　　Must meet the following requirements:(1) all the rollers must be in line, parallel to each other, and keep the horizontal level.(2) all the drum lined, parallel to each other.(3) support structure must be in a straight line, and keep the horizontal level. To this end, after the drive roller and roller rack installation, should be on the conveyor level of center line and make the final alignment.4) then frame fixed to the base or on the floor. After fixed belt conveyor can be installed the feeding and discharging device.5) hang hang a conveyor belt conveyor belt, conveyor belt with first article lays on no-load period of roller, wai after driving drum, and then apply on the overloaded section of the roller. Hung a ribbon can use 0.5 1.5 t hand winch. In article taut band connection, the tension device of the drum should be moved to the limit position, on the car and spiral taut device to pull to move in the direction of transmission device; And pick up device to make the vertical cylinder moved to the top. Before taut conveyor, speed reducer and the motor should be installed, and the good braking device with tilting conveyor confidential. After installation, belt conveyor idler of commissioning is required.
　　In idling of commissioning, should pay attention to in the operation of the conveyor belt running deviation phenomenon, drive part of the operating temperature, activity in the rollers work, cleaning device and the guide plate and the degree of the contact tightly on the surface of the conveyor belt, etc., to make the necessary adjustment at the same time, the parts all can be done only after commissioning on load operations. If the screw tensioning device, in on-load commissioning, operation and adjust its firmness again.
