Description
Technical field
The utility model is related to a kind of hopper wagon door safety device more particularly to a kind of railway transportation bottom door hopper cars
Safe blocking means.
Background technology
Existing railway transportation bottom door hopper car is largely provided with more perfect safety device, but still exists at present
Many old railway transportation bottom door hopper cars of line operation since original designs existing defects, transmission device without safe blocking means,
And it is latched using single-stage driving, single-stage, closings of car door fully relies on the single-stage of car door pull rod from hold depth control.This bottom
There is a phenomenon where car doors to automatically open material leakage often in transportational process for door hopper car, mainly there is two aspect reasons：First is
Car door pull rod is caused to reduce from hold depth after each component wear deformation of bottom opening actuator, goods when being impacted in transportational process
Object, which sinks, easily opens car door material leakage；Second is that bottom each component of enabling control system leaks out, and application reservoir piston is made to act, band moving teeth
Item, gear, transmission shaft, toggle linkage, car door pull rod open car door material leakage.
Material leakage occurs for railway transportation bottom door hopper car, can not only increase product cost, wastes raw material, Iron Contamination curb
The surrounding enviroment of line both sides influence the overall image of railway transportation, while will also result in damage to vehicle itself, not only increase
Car inspection and repair expense, and seriously affect transport and protect production work.
Invention content
The utility model provides a kind of safe blocking means of railway transportation bottom door hopper car, is opened suitable for existing old bottom
Door hopper wagon is improved, can be to avoid material leakage phenomenon by the way that safety catch is arranged；Apparatus structure is simple, is easy to make, installation side
Just.
In order to achieve the above object, the utility model is realized using following technical scheme：
A kind of safe blocking means of railway transportation bottom door hopper car, including safety catch, safety catch hinged-support, axis pin, traction
Chain and haulage chain bearing；The safety catch is arranged in the top of hopper wagon car door pull rod, the side far from car door pull rod rotation axis,
Safety catch hinged-support is fixed on the infundibulate compartment outer wall above car door pull rod, and one end of safety catch is hinged on peace by axis pin
On full gear hinged-support；The hopper wagon opposite with safety catch manipulates and sets haulage chain bearing in side body, and haulage chain is slideably worn
In haulage chain bearing, one end is connect with safety catch, and the other end sets fixed link, and fixed link can be fixed on haulage chain bearing
Mounting hole in, safety catch can be laterally rotated around axis pin under the pulling of haulage chain.
The safety catch is made of baffle and traction end side plate, and baffle is located at right over car door pull rod, and traction end side plate is set
In the outer lower part of baffle.
The haulage chain is iron chains, the both ends of haulage chain respectively in the middle part of the traction end side plate bottom of safety catch, fixed link
It is welded and fixed.
Compared with prior art, the utility model has the beneficial effects that：
1) by the way that safe blocking means are arranged, railway transportation bottom door hopper car material leakage phenomenon can be prevented, reduce product at
This, saves raw material, reduces the surrounding enviroment of pollution Along Railway both sides, while decreasing car inspection and repair expense；
2) apparatus structure is simple, is easy to make, easy for installation；
3) it is improved suitable for existing old railway transportation bottom door hopper car, at low cost, easy to implement, effect is bright
It is aobvious.
Description of the drawings
Fig. 1 is a kind of (protection of front view one of the safe blocking means of railway transportation bottom door hopper car described in the utility model
State).
Fig. 2 is a kind of (unloading of front view two of the safe blocking means of railway transportation bottom door hopper car described in the utility model
State).
Fig. 3 is the A direction views in Fig. 1.
In figure：1. 5. haulage chain bearing of safety catch 2. safety catch hinged-support, 3. axis pin, 4. haulage chain, 6. fixed link 7.
8. car door pull rod 9. of infundibulate compartment operates side body
Specific implementation mode
Specific embodiment of the present utility model is described further below in conjunction with the accompanying drawings：
As shown in Figure 1-Figure 3, the safe blocking means of a kind of railway transportation bottom door hopper car described in the utility model, including peace
Full gear 1, safety catch hinged-support 2, axis pin 3, haulage chain 4 and haulage chain bearing 5；The setting of the safety catch 1 is drawn in hopper wagon car door
The top of bar 8, the side far from 8 rotation axis of car door pull rod, safety catch hinged-support 2 are fixed on the infundibulate of 8 top of car door pull rod
On 7 outer wall of compartment, one end of safety catch 1 is hinged on by axis pin 3 on safety catch hinged-support 2；The hopper wagon opposite with safety catch 1
It manipulates and sets haulage chain bearing 5 in side body 9, haulage chain 4 is slideably threaded through in haulage chain bearing 5, one end and safety catch 1
Connection, the other end set fixed link 6, and fixed link 6 can be fixed in the mounting hole on haulage chain bearing 5, in the pulling of haulage chain 4
Lower safety catch 1 can be laterally rotated around axis pin 3.
The safety catch 1 is made of baffle and traction end side plate, and baffle is located at right over car door pull rod 8, traction end side plate
Set on the outer lower part of baffle.
The haulage chain 4 is iron chains, the both ends of haulage chain 4 respectively with the traction end side plate bottom of safety catch 1, fixed link 6
Middle part is welded and fixed.
When the door hopper car unloading of bottom, drawn by application reservoir piston band carry-over bar, gear, transmission shaft, toggle linkage, car door
Car door is opened in bar transmission, and car door opening can be avoided as long as limiting in above-mentioned transmission system component actuation；This practicality
It is novel to install safety catch 1 additional using in the top of car door pull rod 8, it is simple in a manner of limiting car door pull rod 8 and rotate, and most
Easy mode.
Under the door hopper car normal operation of railway transportation bottom, haulage chain 4 is in relaxation state, and safety catch 1 is being conducted oneself with dignity
Effect is lower to be in vertical state (as shown in Figure 1), can limit the action of the rotation of car door pull rod 8.When unloading, drawn by pulling
The rotation of safety catch 1 is at horizontality (as shown in Figure 2) for 90 ° by chain 4, keeps car door pull rod 8 normal without restriction
Rotation, after 1 pull-up of safety catch, haulage chain 4 is in tensioning state, and the fixed link 6 of 4 other end of haulage chain is inserted into haulage chain bearing
In mounting hole on 5, you can play limit fixed function, prevent the safety catch 1 in Discharging Process from falling.
The preferable specific implementation mode of the above, only the utility model, but the scope of protection of the utility model is not
Be confined to this, any one skilled in the art within the technical scope disclosed by the utility model, according to this practicality
Novel technical solution and its design is subject to equivalent substitution or change, should be covered within the scope of the utility model.
