Description

Conveyor control method with driving motors arranged head and tail

Technical Field

The invention belongs to the technical field of transfer equipment, and particularly relates to a conveyor control method with driving motors arranged end to end, which is mainly applied to monitoring conveying time.

Background

At present, large belt conveyors with driving motors arranged at the head and the tail are increasingly used in application places such as steel, wharfs, mines and the like. In the starting process of the conveyor, the No. 1 driving motor of the head part is usually started first, and the No. 2 driving motor is started after a period of time. Thus, the tail driving roller is started, and the sufficient driving force of the tail driving roller is ensured. The time interval between the activation of drive motor # 1 and drive motor # 2 is typically determined by counting the time that the belt tension wave travels from the leading drive roller to the trailing drive roller.

However, the transmission of the actual tension wave greatly changes with the actual condition of the material load, the ambient temperature, rainy days and sunny days, so that the time is difficult to calculate accurately, and the actual operation inevitably causes the starting failure or the overload of the motor at a local position.

Disclosure of Invention

The invention aims to provide a conveyor control method with driving motors arranged end to end, which has reliable detection precision and avoids overload and starting failure of local motors.

The invention discloses a conveyor control method with driving motors arranged end to end, which comprises the following steps:

step a) a driving motor is respectively connected with the head and the tail of a conveyor, and a tension detection compression roller is arranged on a belt of a material loading section at the tail of the conveyor;

b) fixing a tail car by a stacker belt, starting a head driving motor M001, transmitting a tension wave to the position of a pressure detection compression roller along with an upper belt, and detecting a tension value;

c) the scraper reclaimer pitches around the hinge point under the action of the hoisting system and is responsible for reclaiming materials;

step d), continuously detecting a tension value by using a pressure detection compression roller, and sending a signal for starting a tail motor when a set threshold value is reached;

step e) the tail drive motor M002 is started.

The invention has the beneficial effects that:

1. a belt tension test compression roller is arranged at the tail of the conveyor, and the actual time of the belt tension wave transmitted from the head roller to the tail roller is detected;

2. and when the belt tension detected by the belt tension test pressing roller reaches a set threshold value, starting the tail driving motor.

3. The situation that theoretical calculation cannot adapt to the field environment in the traditional scheme is overcome.

Can carry out the windrow simultaneously, get the material operation, also can realize single heap/singly get the operation, equipment mechanism concentration degree is high, takes up an area of for a short time, and is with low costs.
