Abstract
Disclosed is a switching mechanism for lateral doors of railway carriage trucks and gondola cars, which relates to a door lock device for railway carriage trucks. The utility model comprises a lock hole located at an upper side beam, a lock base located at a lower side beam, a locking device mounted on a door panel, a lock case and a handle holder of the door lock. The locking device comprises an upper cylinder, a supporting spring, a lock pole, a lock pole handle and a lower cylinder. The essential technology is that the upper cylinder and the lower cylinder are respectively located at two ends of the lock pole and are integrated with the lock pole, and the lock case is arranged outside the lock pole and integrated with door panel pressed ribs. The door lock device for railway carriage trucks has the advantages that 1, the door lock is convenient in using, and is safe and reliable, 2, the door lock is simple in structure and convenient in maintenance.
Description
Technical field
The utility model relates to a kind of door lock mechanism of railway freight-car door lock mechanism, especially railway freight gondola car.
Background technology
As everyone knows, the side door switching mechanism of existing load-carrying 60t level railway freight-car open-top car divides goes up lower door lock structure, last door latch structure is the hold-down mechanism of lever band bolt-type structure or straight-bar band off-centre, following door lock mechanism is a lever band bolt-type structure, last door latch structure mechanism complexity, be not easy to maintenance, the door lock component are easily lost the fault rate height.Though following door lock mechanism is by producing certain following slotting power from Beijing South Maxpower Technology Co. Ltd, be provided with above the latch and prevent the lock iron (buting iron that can swing) that moves on the latch, but in actual motion, because the buting iron above the latch is in ceaselessly swing, can not prevent effectively latch on move, still take place often since move in the latch vibration cause in side door from the problem of opening.Therefore existing side door switching mechanism is very insecure.
Summary of the invention
In order to overcome above-mentioned the deficiencies in the prior art, the utility model provides a kind of railway freight-car open-top car new side door open/close machine, this switching mechanism is a monolithic car door lock locking mechanism, by the use while locking and the last lower lock head of opening car door of locking bar handle, thereby realize the locking of car door and the purpose of opening.The employing technical scheme is as follows:
Comprise the lockhole 6 that is positioned at top side rail, be positioned at the lock 4 of bottom side rail, be installed on locking device 1, lock box 2 and door locking handle bearing 3 on the door-plate 5, locking device mainly is made up of last tapered end 1.1, support spring 1.2, locking bar 1.3, locking bar handle 1.4, lower lock head 1.5, its key technology is: go up the two ends that tapered end 1.1 and lower lock head 1.5 lay respectively at locking bar 1.3, linking with locking bar 1.3 is one, and lock box 2 spiral-locks are in the locking bar outside, with door-plate beading integrator.
The utility model compared with prior art has following advantage:
1, easy to use, safe and reliable.
2, simple in structure, easy to maintenance.

Among the figure, the 1st, locking device, the 1.1st, tapered end, 1.2 be support spring, the 1.3rd, locking bar, the 1.4th, locking bar handle, 1.5 be lower lock head, the 1.51st, lower lock head eccentric block, the 2nd, lock box, the 3rd, the handle bearing, 3.1 be support, the 3.2nd, rotating shaft, the 3.3rd, torsion spring, the 3.4th, backstop, the 4th, lock, the 4.1st, lock block, the 5th, door-plate, the 6th, lockhole.
The specific embodiment
Referring to accompanying drawing, it comprises the lockhole 6 that is positioned at top side rail, be positioned at the lock 4 of bottom side rail, be installed on locking device 1, lock box 2 and door locking handle bearing 3 on the door-plate 5, locking device mainly is made up of last tapered end 1.1, support spring 1.2, locking bar 1.3, locking bar handle 1.4, lower lock head 1.5, and its key technology is the two ends that last tapered end 1.1 and lower lock head 1.5 lay respectively at locking bar 1.3, links with locking bar 1.3 to be one, lock box 2 spiral-locks are in the locking bar outside, with door-plate beading integrator; Lock box 2 adopts U type die mould spare; Door locking handle bearing 3 is made of support 3.1, rotating shaft 3.2, torsion spring 3.3, backstop 3.4, and torsion spring and backstop are attached on the support by rotating shaft, and torsion spring is the U type, and an end contacts with support, and the other end contacts with backstop.
The utility model operating principle is as follows: because up and down door lock is integrated and imposes on the mechanical system that side direction external force on the door-plate has formed sealing; on the door-plate lock box that U type die mould spare is adopted at the door lock position is installed simultaneously; spiral-lock is in the door lock rod outside; form the closed section that rigidity is bigger with the door-plate beading; make the side door between door lock that enough rigidity be arranged; improve the force status of car door greatly, played the effect that door lock rod is gone up in protection simultaneously.For making door lock stressed evenly, every fan door is established a cover locking mechanism.
The order of locking a door is: close earlier left-hand door, utilize and carry locking bar 1.3 on the elastic force of support spring 1.2 and tapered end 1.1 is inserted clockwise rotate locking bar handle 1.4 in the top side rail lockholes 6 simultaneously and make locking bar 1.3 rotations, last tapered end 1.1 is pressed into top side rail lockhole 6 by eccentric block; Lower lock head 1.5 is locked by welding or be riveted in the lock 4 on the bottom side rail, the lock block 4.1 of lock 4 just in time blocks the lower lock head eccentric block 1.51 of lower lock head 1.5 during closure state, door-plate 5 is joined together with curb girder up and down simultaneously, and locking bar handle 1.4 pushes in the door locking handle bearing 3.Backstops 3.4 in the door locking handle bearing 3 remain vertical position with locking bar handle 1.4 under the effect of torsion spring 3.3, block, the outside rotation of locking locking bar handle 1.4.And then shut You Men, the order of locking a door is identical with left-hand door, just the direction of rotation of locking bar.When opening the door, pull backstop 3.4, backstop 3.4 is in separates lock-bit, and locking bar handle 1.4 can outwards be rotated, all the other the open the door order and the reversed in order of locking a door.
