Description
Technical field
The present invention relates to the safety devices that a kind of railway freight-car underside gate is closed, especially a kind of on the downside of railway freight-car
The safety device that door 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 be：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.
Summary of the invention
The object of the present invention is to provide a kind of safety devices closed for railway freight-car underside gate.The present invention has
It is convenient that the underside gate of railway freight-car opens and closes, and saves material, and secured, reliable when underside gate closing, railway freight-car handling
The high-efficient feature of person works.
Technical solution of the present invention：A kind of safety device closed for railway freight-car underside gate, includes weight, weight
Upper end through be fixed on downside door butt on fixed pin shaft be movably connected in downside door butt on, on weight vertically be equipped with slide
Slot, the downside door butt of sliding slot lower end are equipped with T-slot, are movably equipped with sliding pin in sliding slot, sliding pin is close to downside door butt
One end be equipped with sliding block, the weight of sliding slot side is equipped with bolt fixation hole, and the weight of the sliding slot other side is equipped with bolt long hole,
L-type bolt is movably equipped in bolt long hole, 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 underside gate of the invention is closed, downside door butt lower end is located in hasp seat, by turning
Dynamic hasp iron, enters hasp iron in the slot of hasp seat, downside door butt is fixed between hasp seat and hasp iron, leads to simultaneously
The weight lower end crossed on the door butt of downside is located above hasp iron, and hasp iron is limited in hasp seat, realizes railway freight-car
Underside gate 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 downside door butt
On T-slot in, weight is fixed, prevents weight from rotating, after so that the lower end of weight is maintained at the top of hasp iron, then passes through handle
One end of L-type bolt after opening slot taking-up, is kept L-type bolt mobile to bolt fixation hole in bolt long hole, L-type is inserted by hand
After one end insertion bolt fixation hole of pin, then one end of L-type bolt is placed in and is closed in slot, prevents L-type from inserting by closing slot
Pin moves on bolt long hole, remains in L-type bolt one end in bolt fixation hole, by sliding pin limit in sliding slot in L-type
In the lower section sliding slot of bolt, guarantees that sliding pin one end sliding block is located in the T-slot on the door butt of downside, prevent Vertical Vibration of Vehicle
So that sliding pin is detached from T-slot because of seismic inertia, realizes when underside gate is closed securely, reliably, do not need to carry out using No. 8 iron wires
Binding achievees the effect that save material；Underside gate open when, by handle by one end of L-type bolt from close slot take out after,
Keep L-type bolt mobile away from bolt fixation hole in bolt long hole, after L-type bolt one end is taken out out of bolt fixation hole, L
One end of type bolt, which is placed in, opens in slot, then moves the sliding pin in weight upper hopper chute, makes the sliding block of sliding pin one end under
After removing in T-slot on side door hinge, the weight on fixed pin shaft is rotated, after leaving weight lower end above hasp iron, then
90 ° of hasp iron of rotation, leaves hasp iron out of, hasp seat slot, i.e., openable underside gate realizes the underside gate of railway freight-car
It is convenient to open, and it is high-efficient that railway freight-car loads and unloads person works.
In conclusion there is the present invention underside gate of railway freight-car to open and close conveniently, material is saved, and underside gate closes
When closing securely, reliably, railway freight-car loads and unloads the high-efficient beneficial effect of person works.
