A cable retractable speed control method, device and mobile operation equipment

Abstract

The invention provides a cable retractable speed control method, device and mobile operation equipment, and relates to the technical field of mobile operation equipment. The method for controlling the cable retracting and unwinding speed includes obtaining the driving speed of the mobile operation equipment; obtaining the real-time radius of the cable reel on the reel of the mobile operation equipment, wherein the cable reel is formed by winding the cable on the reel; calculating the reel according to the driving speed and the real-time radius The expected speed of the driving device; control the driving device to rotate at the expected speed so that the cable retracting speed matches the driving speed. The expected rotation speed of the driving device obtained through the real-time radius and travel speed, and the rotation of the reel driven by the expected rotation speed can match the travel speed of the mobile operation equipment with the retraction speed of the cable during the working process of the mobile operation equipment, and realize the retraction speed The dynamic adjustment of the cable can improve the service life of the cable and ensure the working range of the mobile working equipment.

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
