The conveyor should generally be started under no-load conditions. When several belt conveyors are installed sequentially, a starting device that can be locked should be used to start and stop in a certain order through the centralized control room. In addition, in order to prevent sudden accidents, each conveyor should also be set with a button to start or stop on the spot, and any one can be stopped separately. In order to prevent the conveyor belt from being torn longitudinally for some reason, when the length of the conveyor exceeds 30m, a stop button should be installed at a certain distance (such as 25-30m) along the full length of the conveyor.
The installation of the belt conveyor is generally carried out in the following stages.
1.The installation of the rack frame of the belt conveyor starts from the head frame, and then installs the middle frame of each section in turn, and finally installs the tail frame. Before installing the frame, first of all, the center line should be pulled on the full length of the conveyor, because keeping the center line of the conveyor on the straight line is an important condition for the normal operation of the conveyor belt, so when installing each section of the frame, the center line must be aligned, and the frame should also be leveled, and the allowable error of the frame to the center line is ±0.1mm per meter of machine length. However, the error from the center of the frame on the full length of the conveyor shall not exceed 35mm. When all the single sections are installed and identified, the individual sections can be connected.
2. Install the driving device: When installing the driving device, attention must be paid to making the transmission shaft of the belt conveyor perpendicular to the center line of the belt conveyor, so that the center of the width of the drive drum coincides with the center line of the conveyor, and the axis of the reducer is parallel to the transmission axis. At the same time, all shafts and rollers should be leveled. The horizontal error of the shaft, according to the width of the conveyor, is allowed in the range of 0.5-1.5mm. At the same time as installing the driving device, the tensioning device such as the tail wheel can be installed, and the drum axis of the tensioning device should be perpendicular to the center line of the belt conveyor.
3. Install the roller: After the frame, transmission device and tensioning device are installed, the roller frame of the upper and lower rollers can be installed, so that the conveyor belt has a slowly changing arc, and the spacing of the roller frame in the bending section is 1/2~1/3 of the normal roller frame spacing. After the idler is installed, it should be made to rotate flexibly and briskly.
4. The final identification of the belt conveyor In order to ensure that the conveyor belt always runs on the center line of the roller and the roller, the following requirements must be met when installing the roller, frame and roller:
1) All idlers must be arranged in rows, parallel to each other, and kept horizontally horizontal.
2) All the rollers are arranged in rows, parallel to each other.
3) The supporting structure frame must be in a straight line and keep it horizontally horizontal. For this reason, after the installation of the drive roller and the idler frame, the center line and level of the conveyor should be finally aligned.
5. Then fix the rack on the foundation or floor. After the belt conveyor is fixed, it can be equipped with feeding and unloading devices.
6. Hanging conveyor belt: When hanging the conveyor belt, first lay the conveyor belt strip on the idler of the empty load section, surround the driving roller, and then lay it on the idler of the heavy-load section. 0.5-1.5t hand-cranked winch can be used for hanging strips. When the belt strip is tightened for connection, the roller of the tensioning device should be moved to the limit position, and the trolley and the spiral tensioning device should be pulled in the direction of the transmission device; The vertical pick-up device moves the drum to the top. Before tightening the conveyor belt, the reducer and motor should be installed, and the inclined conveyor should be equipped with a braking device.
