Belt conveyor is generally composed of roller and drive, brake, transmission belt, idler, tensioning, loading, unloading, cleaning and other devices, which are widely used in the mining industry.
Installation sequence of belt conveyor installation main body
The installation sequence of the main body of the belt conveyor should be first to install the head frame, then the middle frame of each section, and finally to install the tail frame.
Before installing the frame, the central position of the conveyor should be determined first. All the working operation centers of the conveyor should be in a straight line.
During the installation of each rack, the longitudinal center position of the conveying distance shall be consistent, and the longitudinal horizontal tilt Angle shall be within the allowable range.
The error range of the single-row frame to the center line should be ±0.1mm, and the error of the whole length of the conveyor to the center of the frame should also be less than 35mm.
All parts can only be connected when all single section racks are placed correctly. After the connection is completed, the firmness of the installation and the accuracy of the center position should be checked.
Installation of drive unit
Should first determine the belt conveyor drive shaft and the center line is in a vertical state, and ensure that the center line of the conveyor and the driving drum width of the central is overlapping, and the traditional axis and the axis of the reducer should also be in a parallel state.
The horizontal error range of the shaft should be within the range of 0.5-1.5mm. In the process of installing the driving device, the corresponding tensioning device can also be installed at the same time. The center line of the belt conveyor and the roller axis of the tensioning device should also be in a vertical state.
Installation of supporting roller in each part
This step is the installation of a belt conveyor is a very important link, it has an important impact on the working efficiency and service life of the belt conveyor.
After successive installation frame, transmission device and tensioning device, it should carry on the roller frame and operation, the installation of the upper and lower roller conveyor belt should be gradually a curved shape, and the ways of the roller frame spacing should be the half of the normal roller frame, after the installation is complete, to ensure that sufficient flexibility and reliability.
Debugging after installation
During the installation of the frame, drum and idler, the following conditions shall also be met:
(1) All rollers should be kept in parallel and arranged in rows with each other;
(2) All idlers shall also be horizontal and parallel and arranged in rows with each other;
(3) After the completion of the preparatory work in the current period, the frame can be installed on the floor or foundation. After the belt conveyor is fixed, the feeding device and unloading device can be installed.
(4) All supporting structure frames shall be kept horizontally parallel and in a straight line state, so the horizontal and central positions of the conveyor shall be corrected immediately after the installation of the driving drum and supporting roller frame is completed.
Also, go ahead in advance for the idling of commissioning operations, to ensure the conveyor belt of the work is not running deviation phenomenon, at the same time in the operation of roller works, degree of conveyor belt surface contact with the guide plate, driving part of the operation parameters such as temperature are also should meet the requirements of the use, but also the necessary debug work, only after, you can proceed to running the commissioning process.
Maintenance of belt conveyor
Clean the
Cleaning is the key point of belt conveyor maintenance.
When cleaning, it should be noted that pressure water should not be used to directly flush the electric parts, such as all kinds of electrical components, motors, switches, etc., nor should roller and bearing pedestal be directly flushed.
The main purpose of cleaning is to ensure personal safety, prevent the spreading of materials, cause the transmission machine to block, prevent dust from interfering with the normal work of electrical appliances, timely find hidden faults of the belt conveyor, and improve work efficiency.
lubrication
The lubrication of the mechanical parts of the belt conveyor is an important part of its daily maintenance. The lubricating oil film can reduce the wear and tear of the mechanical parts and extend their service life. The friction heat generated during the transmission of the machine can also be sent out through lubricating oil.
Daily check
Check the parts, replace the equipment is also the daily work of transmission machine maintenance.
If the belt conveyor bearing is deflected by external force, we should stop the work and check whether the belt conveyor support is stable and whether the debugger is installed in place.
Actually, want to grasp the operation model of belt conveyor, we must according to the electricity with operating rules of belt conveyor, especially the staff to strengthen alert, pay attention to the lowest line between man and machine, not illegal operations, and to use some advanced instruments inspection and prevention of belt conveyor fault, thereby reducing the occurrence of accidents.
