Description

Tipper pressure car signal detection device

Technical Field

The utility model belongs to the technical field of the tipper, concretely relates to tipper pressure car signal detection device.

Background

The tippler is a large-scale mechanical device used for dumping bulk materials of a railway gondola. The loading and unloading machine capable of turning over or inclining the rail vehicle for unloading is suitable for port with large transportation capacity and industrial departments of metallurgy, coal, thermoelectricity and the like. Each tippler is provided with four heavy pressure beams, and each heavy pressure beam independently acts through the hydraulic pressure of an oil cylinder. When a railway wagon enters a turnover machine room to be turned over, a heavy pressure beam is controlled to press a wagon side downwards through a PLC program, a spring upright fixed on one side of the heavy pressure beam is pressed downwards at the same time, after the bottom end of the spring upright contacts with the wagon side, the spring upright retracts upwards along an external spring sleeve, so that a metal induction end at the top of the spring upright is upwards close to a proximity switch fixed above the spring upright on one side of the heavy pressure beam, when the train wagon reaches a specified position, the proximity switch is switched on to transmit a pressing signal, and the PLC program controls to finish the subsequent turnover action; after the raw materials are unloaded, the tipper returns to the zero position, the heavy pressure beam rises and returns according to the PLC program, the spring upright posts return downwards under the action of the springs, the metal induction ends are far away from the proximity switches, the proximity switches send out pressure releasing signals after the heavy pressure beam rises in place, and the tipper program is completed.
