Cable take-up and pay-off speed control method and device and mobile operation equipment

Abstract

The invention provides a cable take-up and pay-off speed control method and device and mobile operation equipment, and relates to the technical field of the mobile operation equipment. The cable take-up and pay-off speed control method comprises the steps that the running speed of the mobile operation equipment is obtained; a real-time radius of a cable reel on a reel of the mobile operation equipment is obtained, wherein the cable reel is formed by winding a cable on the reel; an expected rotating speed of a driving device of the reel is calculated according to the running speed and the real-time radius; and the driving device is controlled to rotate at the expected rotating speed, so that the take-up and pay-off speed of the cable is matched with the running speed. The expected rotating speed of the driving device is obtained through the real-time radius and the running speed, and the reel is driven to rotate at the expected rotating speed, so that the running speed of the mobile operation equipment can be matched with the take-up and pay-off speed of the cable in the working process of the mobile operation equipment, dynamic adjustment of the take-up and pay-off speed is achieved, then the service life of the cable is prolonged, and the operation range of the mobile operation equipment is ensured.

Description

technical field [0001] The present invention relates to the technical field of mobile operation equipment, in particular to a method and device for controlling the speed of retracting and unwinding cables, and mobile operation equipment. Background technique [0002] At present, there are two power supply methods for mobile operation equipment on the market. One is to use battery power supply, and the battery can be directly installed on the mobile operation equipment to realize power supply. The other is to use a cable for power supply, and the mobile operation equipment is electrically connected with the power supply through the cable to realize power supply. Due to the low energy density and volume of the battery, and the heavy load on the mobile operation equipment, the battery-powered battery life is short, and the battery is not commonly used. Most of the cables are used for power supply, and the mobile operation equipment can be realized within the length of the cable...

AI Technical Summary

Problems solved by technology

[0003] In order to improve the working range of the mobile operation equipment, generally the cables will be set as long as possible, resulting in a relatively large radius of the cable roll. Due to the overall mass and inertia of the cable roll, it is difficult to achieve the same speed as the cable retraction speed. Match the travel speed of the mobile work equipment

When the traveling speed of the mobile operation equipment is different from the retracting and unwinding speed of the cable, if the winding speed is too fast or the unwinding speed is too slow, the tension of the cable will be too large, and the wear between the cable and the ground will increase, which will affect the cable. service life

If the winding speed is too slow or the unwinding speed is too fast, the cables will accumulate and reduce the operating range of mobile operating equipment
