Belt conveyors with tire drive rollers

Abstract

The invention discloses a belt conveyor with a tire type transmission drum. The belt conveyor comprises a machine frame, a conveying belt, the drum, a driving device, a tensioning device, a deviation monitoring device and an electric control system. The drum comprises a transmission drum and a turnabout drum, and the transmission drum is the tire type transmission drum which comprises a transmission shaft and an inflation tire group sleeved on the transmission shaft. The inflation tire group comprises a plurality of inflation tires which are sequentially arrayed, and a tire pressure monitoring device is arranged on a hub of each inflation tire. An inflation mechanism is further arranged on the transmission shaft, and the shaft end of the transmission shaft is connected with the driving device. The driving device, the tensioning device, the deviation monitoring device and the tire pressure monitoring devices are electrically connected with the electric control system. The belt conveyor can adjust the external diameter of the transmission drum fast and accurately, achieves power balance, leads power loads of each motor to be balanced and prolongs service lives of the motors.

Description

technical field [0001] The invention relates to a belt conveyor, in particular to a belt conveyor with a tire-type driving roller. Background technique [0002] In the continuous conveying of modern bulk materials, belt conveyors are the main transportation equipment. They are widely used and have the advantages of low transportation cost, large transportation volume, no terrain restrictions and easy maintenance. They are used in mining, metallurgy, ports, Enterprises in working conditions such as docks are increasingly showing their important role. A general belt conveyor consists of a conveyor belt, idlers, rollers and devices for driving, braking, tensioning, redirecting, loading, unloading, cleaning, etc. Among them, the roller is an important part of the belt conveyor. The role of the conveyor is different. The rollers can be divided into two categories: drive rollers and reversing rollers. The function of the drive roller is to transmit the torque provided by the driv...

Problems solved by technology

Under ideal conditions, the power distribution ratio among the motors is the same as the driving force distribution ratio, but in reality, due to the influence of various factors, the actual power distribution of each motor deviates greatly

This not only causes the redistribution of the tension of the conveyor belt, but more importantly, the power load of each motor is unbalanced. In severe cases, one of the motors will be overloaded or even damaged, which will seriously affect production. Therefore, the power balance of the belt conveyor system motor is A necessary condition to ensure its normal operation, however, this problem exists in any occasion that requires multiple motor drives
