Description
Technical field
The invention belongs to Machine Design manufacturing field more particularly to railway transportation equipment field, in particular to a kind of railway
Shipping covered truck door structure.
Background technique
With the continuous development of railway freight, to realize, easily and efficiently handling are required, and do mechanization operation becomes inevitable
Development trend.For that need to increase door opening degree convenient for mechanical equipment operation into the car, therefore, the size and weight of car door are inevitable
Increase.Currently, universal shed car for railway mainly utilizes manpower to be opened and closed car door, large labor intensity, inefficiency.Vehicle is in operational process
In, car door is laterally and vertical vibration amplitude is larger, pulley high failure rate.In violent dither process, existing anti-drop device
It is easy failure, the case where car door falls off occurs.
Summary of the invention
The problem to be solved in the present invention provides a kind of canopy for forklift workability, safe and reliable aiming above insufficient
Vehicle automobile door structure.
The present invention adopts the following technical scheme that realization:
Railway freight box wagon automobile door structure, comprising: left-hand door composition, right Men Zucheng, guide wheel group at, lateral locking device,
Opening/closing door of vehicle seat and pulley composition；It is characterized by:
The left-hand door composition is connected into detachable full-open type by two groups of center locking devices with right door composition, sliding is opened
Close the covered truck door of structure；
The left-hand door composition and right door composition upper end setting multiple groups guide wheel group are at each car door passes through guide wheel group Cheng Gu
Surely it is set to sliding in the guide rail of box car upper door frame.Guide wheel group at car door upper rail composition in slide, make left-hand door composition and
Right door composition moves left and right, and the trapezoidal guide plate of multiple groups is also set up in car door upper rail composition, to guide wheel group in sliding
Play transition guiding role.
The left-hand door composition and right door composition lower end are made of multiple groups pulley, and each pulley composition is being fixed on box car car body
It is moved on track.
It is anti-jump only that the surface of left-hand door composition described further and each pulley composition of right door composition close stance is provided with V-type
Gear.By the anti-jump backstop of V-type and car body track collective effect, pulley composition is limited in vertical and lateral displacement, reaches and subtracts
Small car door is vertical, lateral displacement, to prevent car door from falling off.
Left-hand door composition and right door composition by the weldering of side door frame, upper door frame, lower door frame, door panel and board group of visiting and
At side door frame and middle doorframe are rectangular steel pipe, and damping rubber block is equipped on side door frame, and upper door frame and lower door frame are cold bending tank
Steel, door panel use crimping ripple struction, and upper door frame is L-type crimping plate.
The center locking device is made of lock one, adjustment pad, lock two, bolt, washer, bolt and nut of clip；
Lock one is fixed on left-hand door composition, and lock two is fixed on right door composition, and passes through bolt, washer, bolt and nut of clip connection
It connects lock one and lock two realizes that left-hand door composition couples with what right door formed.
The second level locking device that the lateral locking device is made of container lock and hasp lock.
The left-hand door composition and right door composition are mounted on the opening/closing door of vehicle seat for fork truck opening and closing car door operation, opening/closing door of vehicle
Seat is made of seat board, gusset and backing plate.When forklift workability, the base device that pushes is installed in front end, the fork truck direction of motion and car door are sliding
Dynamic direction is consistent.When fork truck moves downward, push seat and the touching of opening/closing door of vehicle seated connection, pushes car door to slide to the left, realizes car door
It opens, otherwise realizes closing of the door.
The pulley composition is made of pulley, pulley shield, pulley spindle, bearing and backing plate.Its middle pulley is depressurization grooves knot
The idler wheel of structure sliding slot, groove are moved along the track for being fixed on box car car body.
Opening/closing door of vehicle mode of the present invention is that left and right door is opened to towards the movement of car body side simultaneously, while to another
Side movement is closed, by central locking device connection to be whole in, when maintenance two it is separable.Left and right door group ingredient
It is not welded by clod wash channel steel, rectangular square tube, L-type door-plate and crimping ripple door-plate group, equipped with guide wheel group the bottom of at the top of car door
Portion is formed equipped with pulley.The lateral locking device of container lock and hasp lock composition is installed between right door composition and car body.Vehicle
Door close stance is mounted on the anti-jump backstop of V-type right above all pulleys, and car door is vertical, lateral displacement for limiting, and is conducive to subtract
Few pulley is vertical and oscillation crosswise amplitude, reduction pulley failure improve vehicle utilization, meanwhile, can play prevents car door from falling off
Effect.To open and close car door convenient for fork truck, the opening/closing door of vehicle seat for forklift workability is equipped on left and right door.
Compared with prior art, the invention has the following beneficial effects:
It using the anti-jump backstop of V-type, can effectively limit that car door is vertical, lateral displacement, it is vertical and horizontal to advantageously reduce pulley
To vibration amplitude, pulley failure is reduced, improves vehicle utilization, meanwhile, it can play the role of preventing car door from falling off.V-type limit
Structure is compared with traditional disconnecting prevention structure, more securely and reliably.
Opening/closing door of vehicle seat for forklift workability is installed on car door, opens and closes car door convenient for fork truck, it is easy to operate, fast
Victory reduces labor intensity.
The second level lock structure that lateral locking device is formed using container lock and hasp lock, with existing single locking
Mode compares, and improves the reliability and safety of vehicle door locking.
It is equipped with bushing between guide wheel shaft and guiding wheel carrier, the abrasion of wheel shaft and wheel carrier can be effectively reduced, extends and uses the longevity
Life.
