An insulated high-altitude operation vehicle and an automatic limiting method for its insulated working platform

Abstract

The invention discloses an insulating high-altitude operation vehicle and an automatic limiting method for its insulating working platform. The insulating high-altitude operating vehicle includes a working platform limiting device, and the working platform limiting device includes a lower arm inclination detection sensor (5) and an insulating measuring sensor (5). The lower arm length detection sensor (6), the upper arm amplitude detection sensor (7) and the upper arm length detection sensor (8) of the retractable measuring mechanism for the distance rope and the insulating distance measuring rope; use real-time detection of the extension length of each insulating distance measuring rope It is converted into the actual working range of the insulating work platform. When the actual working range is less than the set maximum working range, the operator is allowed to increase the working range. When the actual working range is greater than or equal to the set maximum working range, it is limited. The operator performs all operations to increase the working range, thereby ensuring the stability of the vehicle and preventing the vehicle from tipping over or the boom from being damaged due to the insulated work platform exceeding the operating range.

Description

technical field [0001] The invention relates to an aerial work vehicle and a method for limiting its working platform, in particular to an insulated aerial work vehicle and an automatic limiting method for its insulating working platform, belonging to the technical field of aerial work vehicles.

[0003] With the development of economy and society, people's requirements for the maintenance and quick response of power supply are constantly increasing. ...

AI Technical Summary

Problems solved by technology

[0004] In the prior art, large-height insulating aerial work vehicles usually adopt a double-folding + double-telescopic hybrid boom structure, and in order to meet the ground insulation performance of live work, the last section arm of the upper telescopic boom (the section arm connected to the working bucket ) is generally made of insulating material and is the main insulating end. In order to meet the protection of the ground workers from the low-altitude charged body, the basic section arm of the lower telescopic boom (the section arm connected with the turntable) is generally provided with a section of auxiliary insulation near the turntable. Section, the setting of the auxiliary insulation section makes it impossible to install electronic sensors on the upper telescopic arm to detect the elevation angle and elongation signal of the upper telescopic arm, and then cannot realize real-time monitoring of the amplitude control of the operating state of the boom. The work vehicle does not have the function of limiting the amplitude of the insulating arm. Usually, the operator makes manual judgments on the working platform based on experience, and manually controls the boom to cross obstacles or avoid obstacles. This is only based on the operator's operating experience. There are potential safety hazards in safety actions. If the operator is not familiar with the on-site working conditions or the operation of the work vehicle, the stability of the vehicle will decrease, danger will occur, and the vehicle body will even tip over.

[0005] Chinese patent CN104724645A discloses an amplitude limiting system for insulated aerial work platforms, which discloses determining the expansion and contraction amount of the telescopic boom and the relative to the ground by remotely monitoring the hydraulic pressure of the luffing cylinder and the liquid flow in the luffing cylinder. angle, and then realize the detection and control of the working range of the aerial work platform, but the detection of hydraulic pressure and flow is affected by the power supply, and the detection accuracy is affected by the accuracy of the sensor, and it is necessary to continuously store the signal output by the continuous change of the boom, and the data Larger throughput
