Embodiment Construction

[0013] The accurate positioning and parking control system of the reciprocating mobile equipment of the present invention comprises a laser rangefinder, a PLC controller and a hydraulic control unit of the reciprocating mobile equipment, and the hydraulic control unit of the reciprocating mobile equipment includes a proportional reversing valve; Connected to the controller for measuring the position of the reciprocating device, the PLC controller controls the opening size of the spool of the proportional reversing valve according to the distance between the position of the reciprocating device and the preset parking position, thereby controlling the reciprocating device at Park at the preset parking position.

[0014] Further, when the distance between the position of the reciprocating device and the preset parking position is greater than the preset deceleration distance, the PLC controller controls the spool of the proportional reversing valve to fully open. When the distanc...

Abstract

The invention relates to reciprocating motion equipment, in particular to an accurate positioning parking control system for the reciprocating motion equipment, which comprises a laser range finder, a PLC (programmable logic controller) and a reciprocating motion equipment hydraulic control unit, the reciprocating motion equipment hydraulic control unit comprises a proportional directional valve, and the position of the reciprocating motion equipment is measured through the laser range finder; and the PLC controls the opening size of a valve element of the proportional reversing valve according to the distance between the position of the reciprocating motion equipment and the preset parking position, so that the reciprocating motion equipment is controlled to be parked at the preset parking position, and the problems that the parking position of the reciprocating motion equipment is inaccurate, and faults of a position detection element are difficult to process are solved. The system is applicable to a reciprocating device that moves by rotation of a hydraulic motor.

Description

technical field [0001] The invention relates to a reciprocating mobile device, in particular to a control system for accurate positioning and parking of the reciprocating mobile device. Background technique [0002] In the application of industrial equipment, a reciprocating mobile device is often required to meet the needs of industrial production. The moving distance of the reciprocating mobile device is such as 5-30 meters, and it is required that the equipment can accurately locate and stop during the reciprocating movement. The existing technology The scheme is to use electric motor or hydraulic motor to drive the reducer to drive the equipment to move, and use position detection elements such as travel switches or displacement encoders to control the positioning and parking of the equipment. The existing technical solutions need to install travel switches or displacement encoders on the body of the reciprocating mobile device. In practical applications, the position de...
