Description
Technical field
The utility model relates to the safety devices that a kind of railway freight-car underside gate is closed, especially a kind of to be used for railway freight-car
The safety device that underside gate is closed.
Background technique
When the underside gate of current existing C64, C70 series railway freight-car is closed, using No. 8 iron wires to the folding of underside gate with
Hasp iron is bundled, so that underside gate is closed reliably, this not only makes railway transportation handling person works measure increase, also waste material
Material, but also handling personnel can be allowed when opening underside gate, simply to save trouble and hammering No. 8 iron wires, taken so as to cause underside gate
Button iron and hasp seat are damaged.The reason of leading to the problem of this is: 1, hasp iron does not compress folding in working position, when vehicle exists
When generating upper and lower vibration in operational process, hasp iron causes underside gate to be opened because seismic inertia leaves working position；2, it is artificial because
Element opens underside gate hasp iron, if hasp iron and folding cooperation are more loose, people is not required to by tool, conveniently can be hasp iron
It turns on, underside gate is caused to be opened.Underside gate opening not only results in load loss, and makes vehicle overload circle, brings tight
The traffic safety accident of weight, therefore railway transportation department is transportation safety, prevents C64, C70 series lorry underside gate from running
Cheng Zhong, automatically opens initiation safety accident, and the prior art is just taken with No. 8 iron wires that the folding of lorry underside gate is right with it respectively
Hasp iron is answered to carry out binding measure, it is ensured that transportation safety.
In conclusion there are the downside door butts of railway freight-car and hasp iron all to be bundled with No. 8 iron wires for the prior art,
Cause railway transportation handling person works to measure to increase, wastes material, and the underside gate locking after closing is insecure, unreliable, easily
The technical issues of causing railway freight-car that safety accident occurs in operation.
Utility model content
The purpose of the utility model is to provide a kind of safety devices closed for railway freight-car underside gate.This is practical
It is convenient that the novel underside gate with railway freight-car opens and closes, and saves material, and secured, reliable when underside gate closing, railway
Lorry loads and unloads the high-efficient feature of person works.
The technical solution of the utility model includes: a kind of safety device closed for railway freight-car underside gate, includes weight,
Fixed pin shaft of the upper end of weight through being fixed on the door butt of downside is movably connected on the door butt of downside, is equipped with vertically on weight
Sliding slot, the downside door butt of sliding slot lower end are equipped with T-slot, and sliding pin is movably equipped in sliding slot, and sliding pin is rolled over close to underside gate
One end of page is equipped with sliding block, and the weight of sliding slot side is equipped with bolt fixation hole, and it is long that the weight of the sliding slot other side is equipped with bolt
Hole is movably equipped with L-type bolt in bolt long hole, and weight of the bolt long hole lower end close to sliding slot side, which is equipped with, closes slot, bolt
Long hole lower end is equipped with far from the weight of sliding slot side and opens slot.
It is previously described in the safety device of railway freight-car underside gate closing, the two sides of the bottom of the weight lower end are equipped with
Arc-shaped transition section.
It is previously described in the safety device of railway freight-car underside gate closing, the side of the downside door butt is connected with down
Side door, the downside door butt below weight are movably connected in hasp seat through hasp iron.
It is previously described in the safety device of railway freight-car underside gate closing, the hasp iron connects through hasp iron shaft activity
It connects in hasp seat.
It is previously described in the safety device of railway freight-car underside gate closing, the L-type bolt is vertical with bolt long hole
One end is equipped with handle.
Compared with prior art, when the underside gate of the utility model is closed, downside door butt lower end is located in hasp seat, leads to
Rotation hasp iron is crossed, enters hasp iron in the slot of hasp seat, downside door butt is fixed between hasp seat and hasp iron, together
When be located above hasp iron by the weight lower end on the door butt of downside, hasp iron is limited in hasp seat, realizes railway goods
The underside gate of vehicle is closed convenient；By the sliding pin in mobile weight upper hopper chute, the sliding block of sliding pin one end is made to be located at underside gate
In T-slot in folding, weight is fixed, prevents weight from rotating, after so that the lower end of weight is maintained at the top of hasp iron, then is led to
Handle is crossed by one end of L-type bolt from opening after slot takes out, keeps L-type bolt mobile to bolt fixation hole in bolt long hole, by L
After one end insertion bolt fixation hole of type bolt, then one end of L-type bolt is placed in and is closed in slot, prevents L by closing slot
Type bolt moves on bolt long hole, remains in L-type bolt one end in bolt fixation hole, and sliding pin limit in sliding slot is existed
In the lower section sliding slot of L-type bolt, guarantees that sliding pin one end sliding block is located in the T-slot on the door butt of downside, prevent vehicle vertical
Vibration makes sliding pin be detached from T-slot because of seismic inertia, realizes when underside gate is closed securely, reliably, does not need using No. 8 iron wires
It is bundled, achievees the effect that save material；When underside gate is opened, one end of L-type bolt is taken from slot is closed by handle
After out, keeps L-type bolt mobile away from bolt fixation hole in bolt long hole, L-type bolt one end is taken out out of bolt fixation hole
Afterwards, one end of L-type bolt is placed in and is opened in slot, then move the sliding pin in weight upper hopper chute, make the cunning of sliding pin one end
After block is removed out of T-slot on the door butt of downside, the weight on fixed pin shaft is rotated, leaves weight lower end above hasp iron
Afterwards, 90 ° of hasp iron are rotated further by, leaves hasp iron out of, hasp seat slot, i.e., openable underside gate realizes railway freight-car
It is convenient that underside gate is opened, and it is high-efficient that railway freight-car loads and unloads person works.
In conclusion there is the utility model the underside gate of railway freight-car to open and close conveniently, material, and downside are saved
When door is closed securely, reliably, railway freight-car loads and unloads the high-efficient beneficial effect of person works.
