Defeated to be completed mainly by railway, wherein SQ6 types bilayer car transport vehicle is exactly the principal mode vehicle of railway transportation car, which adopts
Car is shipped with upper layer and lower layer, automobile is loaded and unloaded mainly by rail yard end gate position.Domestic big medium urban car week
Turn big yard and is generally provided with one, two layer of fixed end station platform, and the yard that very little is had enough to meet the need compared with small city car is general only
Equipped with one layer of end station platform, two stop platforms, this people can only be built temporarily by hutching when needing the when of loading and unloading two layers of automobile
The mode that work builds two layers of end station platform is time-consuming and laborious, greatly reduces working efficiency, and then directly affect economic benefit.
Invention content：
Present invention aim to address the two layers of car handling of existing SQ6 types bilayer car transport vehicle, and hutching to be needed to arrive
When build handling channel there are the problem of, provide a kind of swings ladder and SQ6 types vehicle two layers of cab aprons overlap joint, retaining mechanism crosses two layers
Plate and the swing ladder and locking method for swinging the locking mechanism that ladder is locked.
Above-mentioned purpose is realized by following technical scheme：
A kind of swing ladder of locking mechanism, composition include：Ladder is swung, one end of the swing ladder is cut with scissors with folding seat board
Connect, the other end of the described swing ladder is provided with retaining mechanism, and the retaining mechanism includes locking bail, the locking bail with
Locking bail adjusting seat is hinged, and locking bail adjusting seat axis pin and locking nut, institute are respectively welded on the side wall of the swing ladder
The locking bail adjusting seat axis pin stated passes through the strip-shaped hole in the locking bail adjusting seat to be slided with the locking bail adjusting seat
Connection.
The swing ladder of the locking mechanism, the locking nut are threadedly coupled with clamping screw, the locking
Bolt fits with the locking bail adjusting seat right side.
The swing ladder of the locking mechanism, the swing ladder includes two curb girders disposed in parallel, described in two
Curb girder between setting end carriage and one group of crossbeam, be welded with expanded steel diamond mesh, the swing side of the ladder beam on the swing ladder
Tail end opens up pin shaft hole and weld reinforcement ring.
The swing ladder of the locking mechanism, end carriage lower section are welded with bearing, the bearing and cushion pad
It is connected by fixing bolt.
The swing ladder of the locking mechanism, one end of the locking bail and chaining is connected by axis pin, described
The other end of chaining is hinged with the locking bail adjusting seat.
A kind of locking method of the swing ladder of locking mechanism, this method comprises the following steps：Driver starts platform car
SQ6 type bilayer car transport vehicles are moved closer to, are crossed for two layers with SQ6 type bilayer cars transport vehicle when swinging terraced front end cushion pad
After plate contact, platform car must stop at once, and then will swing terraced front end by lifting gear falls, until swinging side of the ladder beam front end
Until being overlapped securely with two layers of cab apron, extracts chaining and lock the axis pin of hook connects, move horizontally locking bail, locking bail adjusting seat
To after suitable position, locking bail gib head is inserted into lower swing in the gap between two layers of cab apron of SQ6 types vehicle and two layers of floor, then
By manually rotating clamping screw, locking bail adjusting seat inner face is withstood, the locking for limiting locking bail adjusting seat and being attached thereto
Hook moves horizontally, it is ensured that locking bail gib head hooks two layers of cab apron of SQ6 types vehicle always, to reach will swing ladder it is tight with two layers of cab apron
Solid purpose.
Advantageous effect：
1. two layers of cab apron of the swing ladder of the present invention and SQ6 types vehicle overlap, two layers of cab apron are locked by retaining mechanism with ladder is swung,
Play the role of stable platform vehicle.
The present invention can be realized by lifting gear and be swung up and down, to adapt to the height change of SQ6 types two layers of cab apron of vehicle.
The swing ladder of the present invention uses rectangular steel pipe welded framework, welds expanded steel diamond mesh thereon, car by when from
To anti-skidding effect, which makes simple, lighter in weight, and lifting is convenient.
Rubber buffer is installed in the swing ladder front end of the present invention, can be risen when swinging ladder and being contacted with two layers of cab apron of SQ6 types vehicle
It is acted on to elastic buffer, to reduce the impact vibration damage to platform car and SQ6 type vehicles.
The present invention is arranged swing side of the ladder tail beam and opens up pin shaft hole and weld reinforcement ring, since curb girder is rhs-structure, wall
Thickness is restricted cannot be too big, therefore weld reinforcement ring can reinforce axis pin and swing the terraced intensity connecting, and improve the stability of device
And safety.
The retaining mechanism of the present invention makes simply, and operation is flexible, convenient and reliable operation, to improve the work that platform car uses
Make efficiency and safety.
