Abstract
The utility model relates to a flexible bridge approach road rail for a railway, which belongs to wired transportation equipment. The utility model adopts short rails; the short rails and sleepers are elastically connected; certain gaps are arranged among the rails to cause the assembled road rail to have good flexibility. Under the action of the certain horizontal pulling force, the utility model can be bent into an arc line which is suitable for butting a track on loading decks of a train ferry. Only one road rail needs to be laid on the connecting bridge for simplifying the structure of the connecting bridge, reducing the dead weight, and reducing the lifter power of the connecting bridge. The utility model has the advantages of large flexibility and convenience, and is especially applied to wharves of the shipping train ferries.
Description
The flexible access bridge rail of a kind of railway, it belongs to wired haulage device.
In the prior art, docking an end is single line, and the other end is multi track, and when circuit one end is fixed, and the other end utilizes general expression road fork to realize the connection of many circuits when being the train ferry loading deck of alterable height usually.This just makes and connects many trapped orbit circuits that common road fork will be arranged on the bridge, make bridge floor very wide, from great, need bigger lift bridge power, and owing to connect on the bridge circuit and fix, require the orbital position on the train ferry loading deck all must not have flexibility by the standard scale setting.
The purpose of this utility model is, design a kind of flexible access bridge rail of railway easily flexibly, track adopts short rail, the syndeton of track and road pillow be convenient to aspect horizontal, to curve when stressed with the train ferry loading deck on the camber line of orbital docking, realize the butt joint rapidly and the purpose of transmission vehicle fast.
Technical solution of the present utility model is: the flexible access bridge rail of a kind of railway, it mainly comprises track, road pillow and sleeper connector, special character of the present utility model is, it also comprises the supporting member at a track rail joint place, track adopts length to be about the short rail of two times of road pillow spacings, each side at rail, per two road occipital branches hold a track, only have three road occipital branches and hold a track in the end of rail, two sides of the relative rail of joint between track road pillow spacing that should stagger mutually, δ=2～6 mm clearance should be left in joint between the track, the sleeper connector adopts oat tail groove structure, the swallow-tail form base of track places the dovetail groove of pillow, and the outside adds to tight a bolt behind cushion and the pressing plate track is anchored on the pillow, and the supporting member at track rail joint place is made up of dovetail groove and pillar, the boring bolt of dovetail groove one end is connected with track, and the lower plane of the lower plane of pillar and road pillow is in the same plane.
The sleeper connector mainly is made up of cushion, pressing plate and alignment pin, and track and road pillow alignment pin location, the interior outside of track add respectively to tight a bolt behind cushion and the pressing plate track is anchored on the pillow.
The supporting member at track rail joint place is a gripper shoe, and gripper shoe is rested the head on a side with bolt in the road of track cantilever end, and the lower plane of the lower plane of gripper shoe and road pillow is in the same plane.
The guiding theory of technique scheme is: track adopts short rail, be connected for elasticity between track and the road pillow, the track rail joint place leaves the gap, make this rail to produce in batches in factory, be assembled into according to Len req at the scene and have flexible rail, only need the auxilliary rail of establishing on the bridge connecting, connect and on the bridge draw-gear is set rail is applied translational force, just can make flexible rail curve with the train ferry loading deck on the camber line of orbital docking.
Effect of the present utility model is, the flexible access bridge rail of this railway, adopted short-track rail, track is connected for elasticity with the road pillow, leaves certain interval between track, makes that the rail after the assembling has flexible preferably, under the effect of certain level tractive force, flexible rail will curve become to be fit to the train ferry loading deck on orbital docking camber line, is connected and only needs on the bridge auxilliaryly establish a rail, simplified the connection bridge structure, conduct oneself with dignity for a short time, reduced the hoist power of connection bridge.This flexible rail has very big flexibility, convenience, uses on the train ferry harbour that is particularly suitable for transporting by sea.

Be an embodiment of the present utility model below, provide details of the present utility model by description and accompanying drawing to this embodiment.
Fig. 1 is the structural plan figure of the flexible access bridge rail of a kind of railway.Every track (1) is all by two road pillows (2) supporting, the length of track (1) is about two times of pillow spacing, joint between two tracks (1) is for rail two sides road pillow spacing that just in time staggers, gap delta=2～6 millimeter should be stayed in the joint of track (1), for making the rail end concordant, must have a longer slightly track (3) to rest the head on (2) supporting by three roads, for producing excessive deformation behind the cantilever end pressurized that overcomes track (1), ad hoc have a supporting member.
Fig. 2 is a dovetail groove type sleeper connection layout.The base of track (1) is a swallow-tail form, just in time with road pillow (2) on dovetail groove match, put cushion (5) and pressing plate (4) in the chassis outer side of track (1), tight a bolt (6) just can be anchored on track (1) on the pillow (2).
Fig. 3 is a double clamp formula sleeper connection layout.Track (1) is located by alignment pin (8) with road pillow (2), and after the interior outside of track (1) base added cushion (5) and pressing plate (7) respectively, tight a bolt (6) just can be anchored on track (1) on the pillow (2).
Fig. 4 is dovetail groove type track rail joint supporting member figure.The swallow-tail form base end of track is stuck in the dovetail groove (12) of supporting member, the one end boring (11) of dovetail groove (12) is fastening dovetail groove (12) and track with bolt, in case the displacement of supporting member play, the lower plane of the lower plane of the pillar of supporting member (10) and road pillow (2) is in the same plane.
Fig. 5 supports board-like track rail joint supporting member figure.Gripper shoe (9) is located at the cantilever end downside of track (1), and with the side of bolton in road pillow (2), the lower plane of gripper shoe (9) is in the same plane with the lower plane that (2) are rested the head in the road.
Fig. 6 is the flexible access bridge lifting of a railway schematic diagram.Fig. 7 is the flexible access bridge rail of a railway translation schematic diagram.Provide the purpose of Fig. 6, Fig. 7 to be further to understand in depth the design phiolosophy and the practical application of this utility model.In Fig. 6,7, put after track (1) and road pillow (2) assembles at one end can the access bridge plate (16) (17) of pitching lifting on, the length of access bridge plate and quantity are determined as required, access bridge plate (16) (17) frame is on the liftable crossbeam (20) (21) that is across on the buttress (14) (15), and the fixed end rail is connected with flexible rail with buttress (13) by access bridge (22).In order to alleviate the weight of access bridge plate (16) (17), the access bridge plate can be only by the width of a circuit or suitably widen and design, and making the access bridge plate go up left rotation and right rotation at hoisting cross beam (20) (21), the maximum angle of rotation satisfies the requirement of outermost railway line on the docking platform.Drag railway line to the location, position that needs by being arranged on the machine that drags (18) (19) on the buttress (14) (15), when circuit to two sideway swivels and longitudinal length when not enough, can increase easily and quickly and connect the rail of having made.
