Abstract
The invention relates to a locking mechanism of a railway freight car, in particular to a locking device arranged on a lower side door of a rail freight gondola car. The device comprises a hasp seat and a hasp iron; wherein, the middle of the hasp seat is a foldout groove, on one side of which a neck is arranged and on the other side of which an installation slot is arranged; one end of the hasp iron is riveted in the installation slot. The key technology is that the hasp seat is provided with a sliding chute communicated with the installation slot, the end part of the hasp seat is provided with a locking iron and a stop catch is arranged at the lower end of the installation slot at the hasp seat. The device has the advantages that when the hasp iron and the locking iron are locked, the locking iron is in the state of self locking for restricting the rotation of the hasp iron, the lock is tight, the rotation of the hasp iron is effectively prevented, thus eliminating the failure of the hasp iron accidentally dapping during the operation of the gondola car and eliminating the potential safety hazard and the goal of tight locking and reliability is further achieved.
Description
Technical field
The present invention relates to a kind of railway truck locking mechanism, particularly relate to the locking device of side door under a kind of railway freight gondola car.
Background technology
Railway freight gondola car is mainly used in shipment coal, ore, building materials, mechanical equipment, steel and timber and other items.The downside door locking apparatus of the most railway freight gondola cars of China mainly adopts hasp seat and button iron component, its action principle is at first will put into the hasp seat with the folding that following side door is fixed together, turn buckle iron is to the draw-in groove of hasp seat then, makes it compress folding and reaches the purpose of locking.But vehicle is in operational process, and button iron is very easily jumped out from the hasp seat, does not only play the effect of locking, has buried huge potential safety hazard on the contrary.
Summary of the invention
The problem to be solved in the present invention is to provide a kind of firm, reliable, safe railway freight gondola car bottom side door hasp lock mechanism at above deficiency.
For achieving the above object, technical scheme of the present invention is: it comprises hasp seat and button iron, and the middle part of hasp seat is the folding groove, has draw-in groove in a side of folding groove, and opposite side has mounting groove, and an end of button iron is riveted in the mounting groove.Its gordian technique is to offer a chute and mounting groove perforation on the hasp seat, in the end of hasp seat lock iron is installed, and the lower end that is positioned at mounting groove on the hasp seat is provided with backstop.
Compared with prior art the beneficial effect that has of the present invention is:
When button iron is in the locking position with lock iron, lock iron is in self-locking state, the rotation of make-up iron plays restriction, locking is firm, preventing to detain iron effectively rotates, thereby removed in the existing open-top car operational process fault that button iron accident is jumped out, eliminated potential safety hazard, reach locking firmly, the failure-free purpose.

Fig. 1 is a structural representation of the present invention;
Fig. 2 is Fig. 1 birds-eye view;
Fig. 3 is a button iron construction scheme drawing of the present invention;
Fig. 4 is that the present invention locks the iron construction scheme drawing;
Fig. 5 is a running condition structural representation of the present invention.
The specific embodiment
Referring to Fig. 1-Fig. 5, the present invention includes hasp seat 2 and button iron 6, the middle part of hasp seat 2 is for placing the folding groove 9 of folding, has draw-in groove 10 at a side along continuous straight runs of folding groove 9, the opposite side along continuous straight runs has mounting groove 12, and an end of button iron 6 is riveted in the mounting groove 12.Its gordian technique is to offer a chute 13 to connect with mounting groove 12 on hasp seat 2, and mounting groove 12 and chute 13 are in same position of center line, and the width of chute 13 is greater than the width of mounting groove 12, and its intermediate location forms step, and vertical plane 16 is arranged.In the end of hasp seat 2 lock iron 4 is installed, lock iron 4 middle parts have an accentric slotted hole 18, and slotted hole 18 is installed on the hasp seat by round pin 3 cooperations, and the lower end of lock iron 4 is an arc surface 17, and the upper end has an eccentric block, and the side of eccentric block is lock iron vertical plane 19.The middle part of button iron 6 is shallow U-shaped 14 bendings, and two ends are tack, and wherein an end is provided with pin-and-hole 15 and is riveted in the mounting groove 12 on the hasp seat to cooperate special-purpose pin rivet 5 and lining 11.The lower end that is positioned at mounting groove 12 on hasp seat 2 is provided with backstop 8.
During use this device is fixed on the underframe curb girder by special-purpose pulling rivet 7, to be placed on the folding 1 of following side door weld together in the folding groove 9, the end that turn buckle iron 6 will be detained iron snaps in the draw-in groove 10, the eccentric slotted hole 18 of lock iron 4 overturns and mobile around fixing round pin 3 the chute 13 of hasp seat in, the arc surface 17 of lock iron lower end contacts with the backstop 8 of hasp seat lower end and spacing, make the vertical plane 19 of lock iron contact and compress with the vertical plane 16 of hasp seat, button iron 6 and lock iron 4 are in the locking position, lock iron 4 is in self-locking state, the rotation of make-up iron 6 plays restriction, preventing to detain iron effectively rotates, thereby removed the fault that button iron accident is jumped out in the existing open-top car operational process, eliminated potential safety hazard, it is firm to reach locking, the failure-free purpose.When lock iron turns to unlock position, the restriction cancellation of lock iron make-up iron, button iron can freely rotate, and following side door can be opened.
