Description
Technical field
The utility model relates to the bottom door opening and closing device of railway hopper car.
Background technology
Be used to load and transport the railway hopper car of bulk freight such as coal, ore, sulphur at present, a cover bottom door opening and closing device is equipped with in its car body bottom, drives bottom door opening and closing mechanism by air driving device or hand-operated gear, realizes the opening and closing of bottom door.The bottom door opening and closing mechanism that has hopper car now can only open and close the bottom door of car body both sides, goods is discharged at the rail both sides, bottom door generally exceeds vehicle gauge of the locomotive, needs the unloading of stopping under door opening state, be only applicable to that ground is provided with the material feeding ditch that can unload simultaneously for both sides or use in the place of high trestle work, goods can not be discharged at the material feeding facility in the middle of the rail.
The utility model content
The purpose of this utility model is exactly the deficiency that exists at said mechanism, and a kind of bottom door opening and closing device of railway hopper car is provided, and it can be discharged at goods the material feeding facility in the middle of the rail, and bottom door is not super vehicle gauge of the locomotive under door opening state, can realize drive-through dumping.
For achieving the above object, the utility model adopts following technical solution:
A kind of bottom door opening and closing device of railway hopper car, it comprises left bottom door, right bottom door, transmission shaft, left lock body, right lock body, long push rod, short push rod, toggle linkage, wherein, left side bottom door and right bottom door are arranged symmetrically in the car body bottom along the longitudinal direction of car center, left bottom door is connected with left lock body and is packed on the car body simultaneously, and right bottom door is connected with right lock body and is fixed on the car body; Transmission shaft is connected by bearing seat and car body, transmission shaft then is connected with engine installation, and long push rod is terminal to be connected with toggle linkage one end, and the toggle linkage other end then is connected with short push rod, the long push rod other end is connected with left bottom door, and the short push rod other end then is connected with right bottom door.
The lower edge place of combining of described left bottom door and right bottom door is a bridging type.
Described left bottom door is connected with car body by each self-corresponding round pin respectively with right door body.
The utility model adopts and splits bridging type bottom door, top locking-type locking mechanism, mainly comprises left and right bottom door, transmission shaft, left and right lock body, long and short push rod, toggle linkage.Bottom door and lock body are separately fixed on the car body by bearing seat by round pin, transmission shaft.Left and right sides bottom door is arranged symmetrically in the car body bottom along the longitudinal direction of car center, be discharged in the middle material feeding facility of rail to realize goods; Left and right sides bottom door lower edge adopts the bridging type structure, avoids causing the crack between a door and its frame gap increase because of bearing cargo weight and Vehicular vibration; Bottom door is not super vehicle gauge of the locomotive under door opening state, can realize drive-through dumping; Adopt top locking-type locking mechanism, have secondary locking function at the state of closing the door, it is less to open the required application force of bottom door process.
Adopt railway hopper car of the present utility model, can operate a pair of bottom door respectively or operate manyly simultaneously by installing different hand-operated gears, can operate a pair of bottom door respectively with the control of different air, driving device or operate many simultaneously the bottom door or the bottom door of the whole train groups of operation simultaneously by the installing power-transfer clutch to bottom door.
Close the course of action of bottom door: the grooved surface that drives transmission shaft and toggle linkage → drive long and short push rod → drive the bearing pin → left and right sides lock body of left and right sides lock body by pin shaft hole by round pin by air or hand-operated gear drives the bearing pin → left and right sides bottom door close synchronously of bottom door, gets final product shipment.
Open the course of action of bottom door: by air or hand-operated gear reverse drive transmission shaft, left and right sides bottom door is opened synchronously, can implement unloading.
The beneficial effects of the utility model are: simple in structure, easy to use, it can be discharged at goods the material feeding facility in the middle of the rail, and bottom door is not super vehicle gauge of the locomotive under door opening state, can realize drive-through dumping.
