Abstract

The invention discloses a rolled cable control system and method. The rolled cable control system comprises an encoder, an acceleration sensor, a first pressure sensor, a second pressure sensor and a controller. The roller cable control method comprises the steps that according to the angle value obtained from the encoder and acceleration obtained from the acceleration sensor, the controller conducts calculation and obtains expected motor differential pressure and outputs an adjustment signal to a hydraulic control device, the hydraulic control device is adjusted for outputting the flow and pressure of hydraulic oil, so that actual motor differential pressure P basically equals to the expected motor differential pressure P, thereby the motor rotating speed and backpressure are adjusted, the tension waving phenomenon of a cable is eliminated, it is guaranteed that the cable tension is kept constant in the vehicle driving process, the rolled cable can be withdrawn and released in synchronization with the vehicle speed, using safety of the cable is improved, and the service life of the cable is prolonged.

Description

technical field [0001] The invention relates to the field of mechanical engineering, in particular to a winding cable control system and method. Background technique [0002] Electric traction engineering vehicles are mostly used in mining engineering and tunnel engineering. They have many advantages such as strong environmental adaptability, low noise, zero emission, low use and maintenance costs, high equipment utilization and high operating efficiency, so they are widely used in various mines , and won good economic benefits for the enterprise. [0003] The power source of electric traction engineering vehicles comes from high-voltage power supply, and the cable needs to be dragged to travel during the work process. The technology of reeling and unwinding and synchronizing vehicle speed is the key core technology. [0004] The synchronization of cable retraction and vehicle speed has the following functions: one is to ensure that the cable retraction follows the movement...
