What is a portable belt conveyor?

Release date:2018-08-11 Author: Click:


Due to a variety of reasons, some users in the purchase of belt machine for its installation and maintenance of some problems from time to time. In order to answer the same question of users, small series belt machine installation and maintenance points are sorted out as follows, I hope to help you!

Belt conveyor generally consists of roller and drive, brake, transmission belt, idler, tensioning, loading, unloading, cleaning and other devices, has a wide range of applications in the mining industry.

Installation of belt conveyor

1. Main installation sequence

The installation sequence of the belt conveyor body should be the first installation of the head frame, and then the middle frame of each section, and finally the installation of the tail frame. Before installing the frame, the center position of the conveyor should be determined first. All working and running centers of the conveyor should be on a straight line. In the process of installing each rack, the longitudinal center position of conveying distance should be consistent, and the longitudinal horizontal inclination Angle must 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 full length of the conveyor to the center of the frame should also be less than 35mm. All parts shall not be connected until all single section racks have been placed correctly. After the connection is completed, the firmness of installation and the accuracy of the center position shall be checked.

2. Installation of drive device

It should be determined that the belt conveyor's transmission shaft and the center line are in a vertical state, and ensure that the center line of the conveyor and the center of the driving drum width is overlapped, and the traditional axis and the axis of the reducer should also be in a parallel state. The horizontal error of the shaft should be within the range of 0.5-1.5mm. In the process of installing the drive 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.

3. Installation of idlers in various parts

This step is a very important part of the belt conveyor installation, it has an important impact on the work 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.

4. Debugging after installation

In the process of installing the frame, roller and idler, the following conditions shall also be met:

(1) all rollers shall be kept parallel and arranged in rows with each other;

(2) all idlers shall also be in a horizontal and parallel state and arranged in rows with each other;

(3) after the current preparatory work is completed, the rack 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 structures shall be in a horizontal and straight state, so the horizontal and central positions of the conveyor shall be corrected immediately after the installation of the driving roller and idler frame is completed.

In addition, go ahead in advance for the idling of commissioning operation, to ensure that the conveyor belt without running deviation phenomenon at work, at the same time in the operation of roller works, degree of conveyor belt surface contact with the guide plate, drive part of the operation parameters such as temperature also meet the application requirements, and make the necessary debug work, only after all, only can carry out commissioning operation.

Maintenance of belt conveyor

1. Clean the

Cleaning is the key of belt conveyor maintenance work. Attention should be paid to the cleaning work. Pressure water should not be used to directly flush the power parts, such as various electrical components, motors, switches, etc., as well as the idlers and bearing blocks.

The main purpose of cleaning is to ensure personal safety and prevent the spreading of materials, which will cause the transmission machine to be blocked and prevent dust from interfering with the normal work of electrical appliances. The belt conveyor can be found in time to hide faults and improve work efficiency.

2. The lubrication

Lubrication of mechanical parts of belt conveyor is an important part of its daily maintenance, lubricating oil film can reduce the wear of mechanical parts, extend the service life, the transmission machine running friction heat can also be emitted through the lubricating oil.

3. Routine inspection

Checking the parts and changing the equipment is also the daily work of transmission machine maintenance. If the belt conveyor bearing deflected by external force, we should stop working, check whether the belt conveyor electrical belt transport support is stable, its debugging 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.
