Embodiment Construction
[0030] Such as figure 1 As shown, the bucket elevator of the present invention includes a driving wheel 3 and a driven wheel 2, a transmission chain 4 is connected between the driving wheel 3 and the driven wheel 2, and one or more hoppers 5 are fixed on the transmission chain 4, and the driving wheel 3 passes through Motor 1 drives, is prior art, certainly also can be the structure of other existing hoists. The present invention is not limited to bucket elevators, and can also be used for elevators of other structures.
[0031] Such as figure 1 , figure 2 As shown, a bucket elevator skidding detection device includes a proximity switch 6 fixed at the edge of the driven wheel 2 of the bucket elevator, and a current sensor ( figure 1 not shown), the proximity switch 6 and the current sensor are electrically connected to the PLC, and the PLC is connected to an alarm; the PLC obtains the pulse signal of the proximity switch 6 and the current parameters of the current sensor, ...

The invention discloses a bucket elevator slipping detection device and a detection method thereof. The detection device comprises a proximity switch which is fixedly arranged at the edge of a drivenwheel of a bucket elevator, and further comprises a current sensor arranged on a motor of the bucket elevator, the proximity switch and the current sensor are electrically connected with a PLC, and the PLC is connected with an alarm. Compared with the prior art, the bucket elevator slipping detection device has the following advantages that 1, the safety is good, the stability is good, the alarm accuracy is high, an alarm can be effectively and timely given for accidents such as slipping, idling and jamming, an operator can be reminded of timely processing, and the normal work of the bucket elevator is guaranteed; 2, a shutdown instruction can be automatically made under the condition that the operator cannot respond timely, and the accidents are avoided; and 3, through the adjustment about whether a corresponding difference value between pulse data or current parameters exceeds a correspondingly preset value by A% or not, and the adjustment about whether the corresponding duration exceeds the preset time or not so as to adapt to various situations, and then the false alarm caused by the transient changes of the rotating speed and the current which are caused by the situations of occasional slipping or the dead weight of a lifting object and the like is avoided.
Description
technical field [0001] The invention belongs to the technical field of bucket elevators, and in particular relates to a bucket elevator skidding detection device and a detection method thereof. Background technique [0002] As a widely used vertical conveying equipment, the bucket elevator is suitable for lifting from a low place to a high place. After the supply material is put into the hopper through the vibrating table, the machine automatically and continuously runs upwards, so the structure is simple and the transmission is convenient. However, in the production of existing bucket elevators, the conveyor belt or conveyor chain often slips or the motor idling or the motor is stuck. If it is not dealt with in time, it will lead to problems such as reduced transmission efficiency, damage to the conveyor belt, and motor damage, which will affect production. Efficiency, there is also a great security risk. Contents of the invention [0003] In order to solve the problems ...
