Description

technical field [0001] The invention relates to a position signal control device for low-speed mobile equipment, in particular to a position signal trigger device for reciprocating motion equipment. Background technique [0002] In industrial production equipment, there are a large number of reciprocating equipment, which are equipped with wheels and reciprocate on a fixed track and within a fixed interval. The shuttle distributor in the sintering production of the iron and steel industry is such a device. This device operates in a dusty, steam-containing environment, and the bulk materials it transports sometimes fall onto the track, and the operating environment is relatively harsh. This type of equipment controls the forward and reverse rotation of the motor and drives the wheels to reciprocate continuously on a fixed track through a transmission system. To control the forward and reverse rotation of the motor, it is necessary to have an accurate position signal of the e...

Problems solved by technology

Since the proximity switch has a high requirement on the sensing distance, the effective sensing distance is 4-10mm. Unlike precision equipment such as machine tool guide rails, this type of equipment has low operating accuracy, and reciprocating motion equipment inevitably has offset when it runs on the track. This offset sometimes exceeds the requirement of proximity switch sensing distance, which will cause the proximity switch not to act.

At the same time, there is chatter phenomenon in the reciprocating motion of this kind of equipment, and the connecting rod or stopper will sometimes directly damage the proximity switch or travel switch.

Therefore, the failure rate of the existing device is relatively high, which affects the normal operation of the reciprocating equipment

[0004] Chinese patent CN201120339410.0 discloses a limit device for a shuttle-type material distribution vehicle. The trigger method is that the contact block installed on the shuttle-type material distribution device directly touches the travel switch, focusing on solving equipment failures caused by ultra-limit movements. Eliminate touch failures caused by deflection and chatter when the shuttle itself is running

[0005] In the prior art, the performance of the proximity switch is improved to reduce the failure rate of the equipment, such as increasing the sensing distance of the proximity sensor, etc. Although the failure rate of the equipment can be reduced to a certain extent, this problem cannot be fundamentally solved. The improvement of the performance of the detection element will also increase the price and increase the maintenance cost
