Description

A kind of pantograph driving device

Technical field

The utility model belongs to rail vehicle field, and in particular to a kind of pantograph driving device.

Background technology

In existing pantograph driving device, mainly there are spring driving and air spring（It is commonly called as air bag, leather bag cylinder） Two kinds of driving, both modes require that vehicle provides compressed air.By air bag driving pantograph in airbag aeration rising bow, By dead weight drop bow during no gas.Simple in structure since air spring is light-weight, manufacture, O＆M cost are low, and damping characteristic is excellent, adopts There is good followability compared with spring driving with the pantograph that air spring drives, current carrying quality is high.Air spring drives at present Pantograph become development trend, domestic and international electric locomotive, EMU and city rail vehicle pantograph driving device are nearly all Air spring is used.

To provide enough pantograph rising bow torques, existing driving device often can only all select the air bullet being relatively large in diameter Spring.The air spring of major diameter can increase pantograph Undercarriage structure, be equivalent to the chopper bar height for increasing pantograph, this will be influenced To vehicle gauge and Dynamic Envelope.

Chinese patent 201610862902.5 discloses a kind of pantograph driving device, and air bag is folded in a longitudinal direction It adds and puts, find that there are following defects in actual application：

Although former and later two air bags are synchronous inflations, there is the thrust of interaction, driving in gas replenishment process The power of pantograph rising bow is the power after superposition, and the thrust that single air bag generates cannot be fully synchronized, is led simultaneously as being longitudinally arranged Cause airbag aeration stroke it is long, these combined factors get up may result in air bag action it is insensitive, rising bow action with inflation acts it Between have hysteresis phenomenon, rising bow action sensitivity is poor.

In addition, being defined to the direction vocabulary being previously mentioned in this case, in track vehicular field, technical staff usually recognizes There are three types of fixed directions：

It is vertical：Vertically perpendicular to the direction of rail level.

Longitudinal direction：Along the direction of track.Before the direction that train is advanced is, after direction in contrast is.

Laterally：Horizontal vertical is in the direction of track.

Utility model content

In view of the above-mentioned problems, the utility model is intended to provide, a kind of action sensitivity is high, can reduce pantograph chopper bar height Pantograph driving device.

The technical solution that the utility model solves the problems, such as is：A kind of pantograph driving device, including being installed under lower arm rod The fixed seat at end connect with fixed seat and around the steel wire rope for being connected on lower arm rod lower end, further includes and be articulated with pantograph chassis front end At least two air bags, all air bags arrange and are synchronized with the movement laterally side by side, and the movable end of all air bags is fixed with steel wire rope Connection, and air bag movable end can drive steel wire rope that lower arm rod lower end is pulled to turn towards the direction opposite with air bag movable end motion track It is dynamic.

It,, can be multiple for single major diameter air bag due to using multiple air bag lateral arrangements in said program Air bag makes the air bag of minor diameter, and guarantees to provide enough thrust again simultaneously, and after this programme, air bag diameter can be with At least reduce half, chopper bar height can accomplish that original half is even following.

In addition, after using lateral arrangement air bag, each air bag is inflated simultaneously, can accomplish to be synchronized with the movement, and stroke contracts Short, the power applied to pantograph is also direct force rather than superposed force, reduces intermediate link so that the action of pantograph is more It is sensitive.

Specifically, air bag movable end is fixedly connected by push plate component with steel wire rope, the push plate component is included with owning The push rod that push plate that air bag movable end is fixedly connected simultaneously, horizontal vertical are set in push plate, the push rod is fixed with steel wire rope to be connected It connects.

Further include the guider being oriented to push plate movement.

Further, a pair is equipped on front side of the lower arm rod lower end with reeded adjustment plate, the fixed seat is equipped with two A, the both ends of steel wire rope are fixedly connected respectively with two fixed seats, and rope body is rotating around being connected in the groove of adjustment plate, the push rod It is fixedly connected in the middle part of rope body.

Further, all air bags are hinged by baffle and pantograph chassis front end, and the baffle is parallel with push plate, are owned Air bag front end is fixed on baffle laterally side by side, and baffle front end is hinged with pantograph chassis.

Preferably, the guider is linear bearing, and what structure included being fixedly connected across push plate and with baffle leads To axis, the bearing portion with steel ball that can be moved along guiding axis, which is fixedly connected with push plate.

Preferably, the stop block that anti-thrust plate is deviate from from guiding axis is equipped in the rear end of guiding axis.

Preferably, the push rod is parallel is equipped with two, and two push rods are fixedly connected with rope body.

The remarkable result of the utility model is：

1. due to using multiple air bag lateral arrangements, the relatively existing air bag of air bag diameter can at least reduce half, can Meet enough driving forces, and the size in the vertical direction of air bag can be reduced, chopper bar height can accomplish original half even hereinafter, Be conducive to the gauge requirement of vehicle.

2. using after lateral arrangement air bag, each air bag is inflated simultaneously, can accomplish to be synchronized with the movement, and stroke shortens, The power applied to pantograph is also direct force rather than superposed force, reduces intermediate link so that the action of pantograph is cleverer It is quick.
