Intelligent arm operating vehicle group capable of operating at low position for installation of cantilever of overhead contact system and operating method

Abstract

The invention discloses an intelligent arm operating vehicle group capable of operating at a low position for installation of a cantilever of an overhead contact system. The intelligent arm operatingvehicle group comprises an aerial work vehicle, an intelligent mechanical arm and a visual identification module, wherein the aerial work vehicle comprises a power flatcar and an aerial work platform;the aerial work platform comprises a crank arm and a hanging basket; the crank arm comprises a base, a rotary table, a basic arm, a two-section arm, telescopic cylinder components, a telescopic arm and a leveling mechanism; the intelligent mechanical arm is arranged on the power flatcar and is provided with a grip for being matched with the visual identification module to transfer the cantileverin order to align a hole in a single ear on an insulator of the cantilever to holes in two ears of a cantilever base on a column. According to the intelligent arm operating vehicle group, the hangingbasket can move below a vehicle for lowering, the structure is stable and reliable, the crank arm is large in operating radius and large in bearing weight, the larger the operating radius of the high-low stroke is, the larger the application range is, more purposes can be achieved, and the mechanization utilization rate of the operating vehicle group of the overhead contact system engineering andthe working efficiency of a user are improved.

Description

technical field [0001] The invention belongs to the technical field of wrist-arm installation, and more particularly relates to a catenary wrist-arm installation smart arm operating vehicle set and a working method. Background technique [0002] At present, the main equipment for the domestic power supply department to install and maintain the catenary arm is the catenary maintenance vehicle, the movable platform (or "bucket" or "hanging basket") that can be lifted or rotated by the standard operation vehicle (group), There are roughly two types. The first type is a catenary overhaul vehicle whose hanging basket can be lifted vertically, and the second type is an aerial work vehicle whose hanging basket can move in a large range through a curved arm. [0003] Both of the above two operating vehicles are equipped with hanging baskets, which can carry out maintenance operations on the catenary. However, in actual use, due to the inconvenient rotation and no power-assisted dev...

AI Technical Summary

Problems solved by technology

However, in actual use, due to the inconvenient rotation and no power-assisted device, there is a height difference of about 2m to 3m from the flatbed vehicle surface or the ground to the standing surface of the hanging basket, and the staff rely on escalators and scaffolding to climb and lie down for maintenance. safety is not guaranteed

[0004] From a functional point of view, the height of the hanging basket of the first type of catenary maintenance work vehicle is relatively high at the initial position, and it only provides a standing position for the maintenance personnel, and does not have the wrist to carry the load from the ground or the flatbed of the operation vehicle group. The operation function of the arm or other heavy objects to the high-altitude operation point does not have a large operating radius, and neither can reach the lower working surface nor the higher position, making the comprehensive maintenance efficiency low and limiting Scope of application and purpose, especially for technical types of work with heavy workload or heavy load, such as installation of additional wires, installation of catenary wrist arm, etc., which brings great constraints

The second type of aerial work vehicle has a large operating radius for aerial work, and its telescopic arm is relatively long and heavy, which makes the load of the rotating mechanism relatively large. This structure limits its ability to be lowered to a lower working surface. It is impossible to carry heavy objects such as wrist arms on the ground or on flatbed vehicles (installed in place), so it is also impossible to complete tasks such as mounting the wrist arms. Simply increasing the number of curved arms or sampling multi-section rotary folding arms cannot be achieved. low function

This makes the utilization rate of the work vehicle low and the labor intensity of the workers is high
