Description
Technical field
The utility model relates to the longitudinal bottom door opening and closing mechanism of a kind of railway hopper car, belongs to bottom door opening-closing mechanism for railroad hopper wagon field.
Background technology
Current China railways hopper wagon bottom door switching mechanism mainly adopts two kinds of linkage, i.e. double embrace " machete " formula and top locking-type bottom door opening and closing mechanism." machete " formula bottom door opening and closing mechanism adopts bias to cross dead point locking mechanism, and this mechanism driving efficiency is low, wastes time and energy.Top locking-type switching mechanism only need overcome the force of rolling friction between lock body and bottom door pin when opening the door, required application force is less, stable drive, light, flexible, but lock body or lock body bear beam once damage, then and bottom door will be opened automatically, cause goods to unload leakage, there is larger potential safety hazard.
Summary of the invention
The purpose of this utility model is the deficiency existed for domestic railway hopper car opening/closing mechanism, there is provided a kind of to push up based on locking-type switching mechanism, add secondary locking device, under the prerequisite not affecting driving efficiency, can preventing the goods caused because break down in lock body position from unloading leakage, the longitudinal bottom door opening and closing mechanism of railway hopper car that hopper car runs can be substantially increased.
For achieving the above object, the utility model adopts following scheme:
The utility model comprises left lock body, right lock body, upper driving device, bottom transmission shaft, toggle linkage, short push rod, long push rod, pull bar, it is characterized in that: at the pull bar and long push rod connecting portion that connect left lock body, secondary locking device is set, at the pull bar and short push rod connecting portion that connect right lock body, secondary locking device is set, secondary locking device by hook lock, short pipe link, long pipe link, and is fixed on the hook lock bottom door pin composition on bottom door doorframe.
Described long pipe link one end is flexibly connected with short push rod and pull bar, centre is flexibly connected with short pipe link, and the other end is flexibly connected with funnel end plate; Hook lock one end is flexibly connected with short pipe link, centre is flexibly connected with funnel end plate, and other end hook lock opening and hook lock bottom door pin phase hasp, hook lock bottom door pin is welded on the doorframe of bottom door two ends.
The utility model has the advantages that: to push up based on locking-type switching mechanism, add secondary locking device, substantially increase the safety that hopper car runs.

Detailed description of the invention
As shown in Figure 1: the utility model is on the basis of existing top locking-type switching mechanism, secondary locking device is increased with long push rod 3 connecting portion at the pull bar 2 connecting left lock body 1, secondary locking device is increased with short push rod 7 connecting portion at the pull bar 2 connecting right lock body 8, secondary locking device is by hook lock 10, short pipe link 11, long pipe link 12, and the hook lock bottom door pin 9 be fixed on bottom door doorframe forms; Described top locking-type switching mechanism comprises upper driving device 6, bottom transmission shaft 5, toggle linkage 4, short push rod 7, long push rod 3, right lock body 8, left lock body 1, pull bar 2.Upper driving device 6 is fixedly connected with bottom transmission shaft 5, and bottom transmission shaft 5 is fixedly connected with toggle linkage 4.Toggle linkage 4 upper end is flexibly connected with short push rod 7 one end, and lower end is flexibly connected with long push rod 3 one end.Short push rod 7 other end (opposite side is long push rod 3), to be flexibly connected with pull bar 2 one end and long pipe link 12 one end.Pull bar 2 other end is flexibly connected with lock body bottom door pin 15, and lock body bottom door pin 15 is welded on the doorframe of bottom door two ends.Lock body bottom door pin 15 and right lock body 8 chute are fitted.Long pipe link 12 other end is flexibly connected with funnel end plate 13, centre is flexibly connected with short pipe link 11.Hook lock 10 one end is flexibly connected with short pipe link 11, centre is flexibly connected with funnel end plate 13, and other end hook lock opening and hook lock bottom door pin 9 phase hasp, realize secondary locking; Hook lock bottom door pin 9 is welded on the doorframe of bottom door two ends.
When bottom door is opened, thrust passes to bottom transmission shaft 5 by upper driving device 6 and makes its clickwise, then be long push rod 3 by short push rod 7(opposite side) power is divided into two parts, it is left lock body 1 that a part passes to right lock body 8(opposite side by pull bar 2), lock body bottom door pin 15 is rolled in lock body chute, simultaneously, another part power is by long pipe link 12, short pipe link 11 passes to hook lock 10, the fulcrum left-hand revolution that hook lock 10 is formed around self and funnel end plate 13, hook lock and hook lock bottom door pin 9 depart from, open secondary locking device, now lock body bottom door pin 15 still rolls in lock body chute, when lock body bottom door pin 15 departs from lock body chute completely, bottom door is opened.
When bottom door is closed, thrust passes to bottom transmission shaft 5 by upper driving device 6 and makes its left-hand revolution, equally, it is left lock body 1 that part power passes to right lock body 8(opposite side by pull bar 2), lock body bottom door pin 15 is rolled in lock body chute, simultaneously, another part power is by long pipe link 12, short pipe link 11 passes to hook lock 10, the fulcrum clickwise that hook lock 10 is formed around self and funnel end plate 13, hook lock snaps on hook lock bottom door pin 9, form secondary locking, now lock body bottom door pin 15 still rolls in lock body chute, when lock body bottom door pin 15 falls into lock body chute completely, bottom door is closed completely.
