Automatic parking secure protection device for mobile device using secure sliding line

Abstract

The invention discloses an automatic shutdown safety protection device with safety slider wires for mobile devices, and comprises a slider wire conductor, a slider wire sheath, a collector, collectorcarbon brush sheets and a circuit breaker with separately-excitated slip, as well as an insulation isolator and a shorting switch; an insulation isolator with the same cross section shape as that of the slider wire conductor is arranged on at least one-phase slider wire conductor on a movement limiting position of a mobile device; the insulation isolator can insulate and divide the slider wire conductor into a limit position front part and a limit position rear part which are connected through the shorting switch; the limit position rear part is connected with the separately-excitated slip coil on the circuit breaker through the slip switch; the longitudinal length of the insulation isolator is smaller than that of the carbon brush sheet of the collector; the invention can effectively control stopping or running of the mobile device, avoid such life-and-death equipment failure accidents as traveling wheels off-road and etc, and eliminate safety hidden trouble and lower maintenance cost.

Description

technical field [0001] The invention relates to an automatic parking safety protection device for mobile equipment, in particular to an automatic parking safety protection device for mobile equipment using a safety sliding contact line. Background technique [0002] In large-scale production and manufacturing enterprises, a large number of mobile equipment running along the track are used. This mobile equipment uses trolley lines to supply power in a three-phase three-wire or three-phase four-wire system. The trolley line is parallel to the track and installed along the extension direction of the track, usually made of aluminum or copper. A collector is installed on the mobile device, and the carbon brush of the collector slides in the groove of the trolley line, and the power supply supplies power to the mobile device through the trolley line → carbon brush → cable. In order to prevent these devices from leaving the track at the end of the track, causing equipment and pers...

AI Technical Summary

Problems solved by technology

[0003] However, damage or circuit failures sometimes occur in the use of the above-mentioned limit switches, causing the mobile equipment to fail to stop, causing major equipment accidents such as the wheel going down the road, and causing financial and material losses.

Obviously, this limit protection method has potential safety hazards
