A kind of coupler traction rod tooling

Technical field

The utility model is related to a kind of coupler traction rod toolings, belong to rail vehicle traction field.

Background technology

Traction of the tramcar vehicle when unpowered at present is generally power using traction locomotive or road rail vehicle, profit With the traction hitch on traction locomotive or road rail vehicle and head vehicle hitch tramcar vehicle is drawn or pushes to the connection of hook Move ahead.The shortcoming of this mode of traction is used at present：

1st, stress operation point-blank can not be ensured by drawing hitch and draw bar, during vehicle forward is pushed Traction hitch can form angle with draw bar, the hidden danger that there is the head-shield that collides with；

2nd, the traction hitch cost being installed on traction locomotive or road rail vehicle is high, simultaneously because heavier-weight causes Operating personnel are inconvenient in installation, disassembly process, and dangerous.

Utility model content

The utility model is intended to provide a kind of coupler traction rod tooling, and the tooling is in existing tramcar vehicle or rail-road two With a draw bar is increased between the traction hitch on the rail vehicles such as vehicle and head vehicle hitch, draw bar can meet a variety of differences The switching of hitch model uses, and can reduce manufacture hitch cost, be easy for installation and removal simultaneously.

To achieve these goals, technical solution is used by the utility model：

A kind of coupler traction rod tooling, including draw bar main body；It is characterized in that, the draw bar main body is equipped at least Three hitch connection positions, wherein at least one hitch connection position are the head vehicle hitch connection position being connect with head vehicle hitch, remaining Connection position is the tractor hook connects position being connect with the hitch of vehicle to be drawn；The both sides of the head vehicle hitch connection position are equipped with The position limiting structure for preventing a vehicle hitch from swinging.

As a result, traction hitch of the utility model on the rail vehicles such as existing tramcar vehicle or road rail vehicle with Increase a draw bar between head vehicle hitch, draw bar can meet a variety of different hitch model switchings and use, and reduce manufacture Hitch cost, is easy for installation and removal simultaneously.Position-limit mechanism can prevent the traction on traction locomotive or road rail vehicle simultaneously Hitch swings, and avoids the head-shield that collides with.

Embodiment according to the present utility model can also make the utility model further optimization, below for optimization after The technical solution of formation：

For convenience by the locking of corresponding hitch at hitch connection position, bolt there are one dresses at each hitch connection position, Corresponding hitch is mounted at corresponding tractor hook connects position by the bolt.In order to ensure the reliability of hitch connection, each There are one disconnecting prevention structures for dress on bolt.The disconnecting prevention structure is split pin.

Preferably, the position limiting structure is to be arranged on a limited block for the both sides of vehicle hitch connection position.

Preferably, the head vehicle hitch connection position is surrounded by the first top plate, the first bottom plate and two limited blocks.

Embodiment according to the present utility model, sets that there are three hitch connection positions in the draw bar main body, one of them is Head vehicle hitch connection position, two are tractor hook connects position；Three hitch connection positions are integrally arranged in a linear.

Preferably, at least one of described tractor hook connects position is formed by the second top plate and the second bottom plate, and at least one It is a to be formed by third top plate.

By above structure, between the traction hitch and head vehicle hitch on existing tramcar vehicle or road rail vehicle Increase a draw bar, draw bar can meet two kinds of different hitch model switchings and use, and greatly reduce traction hitch system Cause this and operating personnel it is simple in installation, disassembly process, conveniently, it is safe and reliable.

Preferably, the traction hitch is the hitch of tramcar vehicle.

Compared with prior art, the beneficial effects of the utility model are：

1）Using to hook bayonet and type of attachment is inlayed, a draw bar can meet two kinds of different hitch models switchings and make With.

2）Draw bar is simple in structure, and operation is light, safe and reliable.

3）Draw bar manufacture is at low cost.

4）Limited block is increased to both sides at hook bayonet, prevents traction hitch on traction locomotive or road rail vehicle or so pendulum It is dynamic.

Specific embodiment

The utility model is described in detail below with reference to attached drawing and in conjunction with the embodiments.It should be noted that not conflicting In the case of, the feature in embodiment and embodiment in the utility model can be combined with each other.For sake of convenience, hereinafter such as There are " on ", " under ", "left", "right" printed words, only represent consistent with the upper and lower, left and right direction of attached drawing in itself, not to structure Play restriction effect.

A kind of tramcar coupler traction rod tooling, as shown in Figs. 1-3, mainly by draw bar main body, bolt 11,21,31, Split pin 12,22,32 forms.Draw bar main body mainly directly forms or welds spelling by a monoblock cast(ing) steel with milling machine production and processing It connects, the tractor hook connects on traction locomotive or road rail vehicle.Bolt 11,21,31, split pin 12,22,32 are led If it is located by connecting the corresponding hitch of fastening.

It is set in the draw bar main body of the utility model as a result, there are three hitch connection position, one of them connects for head vehicle hitch Position is connect, two are tractor hook connects position；Three hitch connection positions are integrally arranged in a linear.The two of the head vehicle hitch connection position Side, which is equipped with, prevents the limited block 14 that a vehicle hitch swings.

As shown in Fig. 2, the head vehicle hitch connection position is surrounded by the first top plate 1, the first bottom plate 13 and two limited blocks 14. One in the tractor hook connects position is formed by the second top plate 2 and the second bottom plate 23, and one is formed by third top plate 3.

During operation, first draw bar is installed to the traction hitch on traction locomotive or road rail vehicle, and with bolt 11 Fastening installation connection, then limited with split pin 12；Slow down mobile traction locomotive or road rail vehicle again, treat draw bar 1 and head vehicle Hitch connection stops moving ahead, and itself and head vehicle hitch is fastened installation connection with bolt 21,31, then limited with split pin 22,32. It is simple during whole operation, light, safe and reliable.The utility model increases between existing traction hitch and head vehicle hitch Add a draw bar, design requirement is as follows：

1st, traction hitch ensures that traction hitch draws or push vehicle with draw bar using groove and double positioning pin design forms When always in straight line stress, avoid the presence of head-shield hidden danger of colliding with；

2nd, draw bar can meet two different hitch switchings, reduce traction hitch and be manufactured into this and operating personnel In installation, disassembly process simply, conveniently, safely.

The content that above-described embodiment illustrates should be understood to that these embodiments are only used for being illustrated more clearly that the utility model, Rather than limitation the scope of the utility model, after the utility model has been read, those skilled in the art are new to this practicality The modification of the various equivalent forms of type each falls within the application range as defined in the appended claims.
