Abstract

The utility model relates to a current collector for urban subways or light rail vehicles, particularly a current collector with a third rail disengaging device. The current collector solves the problem that a current collector for receiving current at the upper part of the existing three rails dose not have a third rail disengaging device to cause that the current collector which needs to be disengaged from the third rail can not be disengaged from the third rail. The current collector comprises a fixed seat and a transverse arm hinged with the fixed seat through a centre shaft, wherein one end of the transverse arm is fixed with a collector shoe, and a hook mounting seat is fixed on the transverse arm; a hook is hinged with the hook mounting seat, and a knob spring is arranged between the hook and the hook mounting seat; the upper part of the fixed seat is fixed with a hook plate mounting seat, and a hook shaft is arranged on the hook plate mounting seat. The current collector of the utility model is additionally provided with the third rail disengaging device, so that the current collector can be disengaged from the third rail safely in emergency situations or as required and the third rail is stopped to supply power for vehicles. The utility model has the advantages of convenient users' installation, use and maintenance, compact structure, stable performance and reliable working.

Description

Have the pantagraph current collector that breaks away from three rail devices

Technical field

The utility model relates to the pantagraph current collector that city underground or light rail vehicle are used, and is specially a kind of pantagraph current collector that breaks away from three rail devices that has.

Background technology

Pantagraph current collector is fixed on city underground or the light rail vehicle bogie truck, and pantagraph current collector contacts with the 3rd rail (power rail) of track during vehicle operating, for operational vehicle provides required power supply.Pantagraph current collector is divided into three rails (conductor rail) top and accepts the pantagraph current collector of electric current and the pantagraph current collector that electric current is accepted in three rail bottoms.The pantagraph current collector that electric current is accepted on present three rail tops does not break away from the device of the 3rd rail, when line fault or vehicle need overhaul, must whole process stop power supply, and influences other vehicle operating, and poor stability; Make troubles also for simultaneously the maintenance of pantagraph current collector.

Summary of the invention

The utility model solves the pantagraph current collector of accepting electric current in existing three rail tops and does not break away from the 3rd rail device, makes pantagraph current collector when needs break away from the 3rd rail and the problem that can't break away from provides a kind of pantagraph current collector that breaks away from three rail devices that has.

The utility model is to adopt following technical scheme to realize: have the pantagraph current collector that breaks away from three rail devices, comprise permanent seat, pass through axis pivotally attached transverse arm with permanent seat, end at transverse arm is fixed with shoegear, on transverse arm, be fixed with the hook mount pad, be hinged with hook with the hook mount pad, between hook and hook mount pad, be provided with the turn-knob spring; Top at permanent seat is fixed with hook plate installation base, and hook plate installation base is provided with the hook axle.When pantagraph current collector need break away from the 3rd rail (shoegear does not contact with the 3rd rail), lift transverse arm, transverse arm rotates up around axis (jointed shaft), when transverse arm rotates to certain angle, hook touched the hook axle before this, continued to raise transverse arm, and hook just can be under the effect of turn-knob spring, tightly hook the hook axle, finish the disengaging action of pantagraph current collector; If hook is broken away from, make shoegear contact the 3rd rail, then need to knock (bump gently) hook afterbody (transverse arm) with a non-conductive bakelite rod, hook will break away from the hook axle, and under the deadweight effect of transverse arm, shoegear, transverse arm falls, shoegear contacts the 3rd rail.

Pantagraph current collector described in the utility model has installed additional and has broken away from the 3rd rail device, make pantagraph current collector break away from the 3rd rail safely and reliably in can or needing at emergency situation, ends the 3rd rail vehicle is powered, and user friendly installation, use and overhaul.This pantagraph current collector compact conformation, stable performance, reliable operation.

The specific embodiment

Have the pantagraph current collector that breaks away from three rail devices, comprise permanent seat 1, pass through axis 13 pivotally attached transverse arms 16 with permanent seat, end at transverse arm is fixed with shoegear 17, on transverse arm, be fixed with hook mount pad 12, be hinged with hook 9 with the hook mount pad, between hook 9 and hook mount pad 12, be provided with turn-knob spring 10; Be fixed with hook plate installation base 4 on the top of permanent seat 1, hook plate installation base is provided with hook axle 8.Be to realize pivotally attached between hook 9 and the hook mount pad 12 by hook axle 11.

Side at hook mount pad 12 has screw, is screwed with adjustable bolt 14 in the screw.Adjustable bolt is used to adjust the angle of hook 9.The degree of depth that is screwed into by adjustable bolt 14 is adjusted the correct position of hook 9.

On adjustable bolt 14, be with jam nut 15.After adjust the position of hook, lock with jam nut 15, its position is remained unchanged.

This pantagraph current collector also comprises safety mechanism.The purpose of safety mechanism is to guarantee that releasing mechanism can not produce misoperation, makes pantagraph current collector work more reliable.This safety mechanism comprises an end by jointed shaft 6 and hook plate installation base 4 pivotally attached handles 18, the axle head of jointed shaft 6 (passing through bolt) is fixed with safety plate 7, be fixed with spring at the top of permanent seat 1 and hang 2, one end of spring 3 is fixed on the middle part (on the projection) that spring is hung on 2, the other end is fixed on handle 18, is provided with limiting stopper 5 at the top of hook plate installation base 4.There are two control positioies in safety mechanism: insurance position and disengaging position.When needs break away from the 3rd rail, upwards spur handle 18 (spacing) to limiting stopper 5, handle drives jointed shaft 6, jointed shaft 6 drives safety plate 7, make safety plate 7 open (as shown in Figure 3), because the effect of spring 3, mechanism remains at this position, at this moment transverse arm 16 is lifted, hook 9 will catch on hook axle 8, finishes to break away from action; Otherwise safety mechanism is in insurance position (as shown in Figure 2), and safety plate 7 is positioned on the hook axle 8, vibration in any case, hook 9 can not hook hook axle 8 automatically and break away from the 3rd rail, because the effect of spring 3, safety plate 7 is close on the hook axle 8 all the time, plays safety effect all the time.
