Embodiment Construction

[0013] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0014] figure 2 It is a block diagram of a control device for underspeed skidding of a reclaimer suspension skin according to an embodiment of the present invention. Such as figure 2 As shown, the control device includes a speed state detection device 20, which is used to detect the speed state of the reclaimer suspension skin; and a control device 21, which is used to stop reclaiming when the reclaimer suspension skin is in an underspeed state The rotary operation of the machine, and keep the reclaimer hanging skin to continue to run.

[0015] The main reasons for the underspeed slippage of the reclaimer's suspension belt are: 1. When the belt is running i...

Abstract

The invention discloses a control method for slack sliding of a taker suspension belt. After the taker suspension belt is started, the method comprises the following steps of: a, detecting the speed state of the taker suspension belt; and b, stopping the rotation operation of a taker if the taker suspension belt is under a slack rate, maintaining the taker suspension belt to run continuously, so as to avoid the heavy-duty stopping in the slack sliding and the subsequent heavy-duty starting.

Description

technical field [0001] The invention relates to the field of engineering technology, in particular to a control method and control equipment for under-speed skidding of the overhanging skin of a reclaimer. Background technique [0002] Belt underspeed slipping fault is one of the common faults in belt conveyor control. When the belt conveyor underspeed slips, the belt will rub against the drive roller, which will generate a lot of heat, and the service life of the belt will be affected when the slippage is light. , if the slippage is severe and the heat cannot be dissipated in time, it may cause the tape to burn, which will not only affect normal production, but also pose a threat to the safety of equipment and personnel. [0003] Therefore, the underspeed detection switch is generally installed on the reclaimer, and the underspeed skid control of the overhanging skin of the reclaimer is realized through PLC. The control process is as follows: figure 1 As shown, after the s...
