Abstract
The invention belongs to the technical field of rail wagons, particularly relates to a rail wagon end door opening and closing device and solves the problem that existing rail wagons are not provided with end doors or the end doors can only be opened and closed manually. End doors are arranged at the end of a rail wagon, mutually-parallel guide rails are arranged on two sides, corresponding to the end doors, of a wagon end body, a hollow shaft capable of rotating relative to the guide rails is arranged at the top ends of the guide rails, the middle of the hollow shaft is fixedly connected with one end of a crank shaft vertical relative to the hollow shaft, the other end of the crank shaft is connected with a two-way cylinder push rod, a two-way cylinder is mounted on the body, symmetrical two groups of cranks and connecting rods are mounted on the portions, corresponding to the end doors, of the hollow shaft, the cranks are welded to the hollow shaft, and the cranks and the upper ends of the connecting rods as well as the lower ends and the end doors are connected via round pins. All transmission parts are driven through the two-way cylinder pneumatically or hydraulically to enable the end doors to be opened and closed, and operation is quickened. Operation can be executed on any side of the wagon manually, and reliability and convenience in operation are improved. Due to the fact that the end doors are vertically arranged on the end wall, pressure of cargoes on the end doors is small, and the end doors are opened and closed with less effort no matter by wind pressure, hydraulic pressure or hand.
Description
Technical field
The invention belongs to the technical field of railway freight-car, be specifically related to a kind of railway freight-car end device for opening/closing door.
Background technology
Door is not all held in general railway freight-car end, also can only manual opening and closing even if having, not by the end door of air pressure or hydraulic pressure opening and closing.
Summary of the invention
The present invention does not hold door or end door can only the problem of manual opening and closing to solve existing railway freight-car, provides a kind of railway freight-car end device for opening/closing door.
The present invention adopts following technical scheme to realize:
A kind of railway freight-car end device for opening/closing door, end door is arranged at railway freight-car end, on the car body of lorry end, corresponding end door both sides arrange guide rail parallel to each other, guide rail top arrange can opposite rail rotate hollow shaft, one end of its vertical crank throw relatively is fixedly connected with in the middle part of hollow shaft, the other end of crank throw connects two-way cylinder push rod, two-way cylinder is installed on car body, two symmetrical suite handle and connecting rods are installed at the position of hollow shaft corresponding end door, crank and welding hollow shaft, crank adopts round pin to be connected with small end, connecting rod lower end with end door.Described end door arranges two groups.
Manual coupler is welded respectively in described hollow shaft two ends, and described manual coupler arranges some four square holes at circumferencial direction, and end inner circumferential is four square holes, and periphery is square.
Small end arranges limiting plate, and limiting plate bottom upwards bends, welded top is on crank.
Have upper door frame outside end header, upper door frame top is V-shaped groove structure, and end header installs flashing board additional, and flashing board extends downwardly in groove along V-shaped groove, and the position of the corresponding V-shaped groove of guide rail has leaking hole.
Hinge structure of the present invention has following beneficial effect: pneumatic or surge and drive each driving parts to make the opening and closing of end door by two-way cylinder, swift to operate.Manually in lorry any side operation, operating reliability and convenience can be improve.Because end door is arranged vertically on headwall, end door is very little by cargo pressure, is therefore that blast, hydraulic pressure or hand switch end door are all very laborsaving.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention,
Fig. 2 is partial enlarged drawing of the present invention,
Fig. 3 is the rainproof schematic diagram of end door of the present invention,
In figure: 1-hollow shaft; 2-crank throw; 3-crank; 4-connecting rod; 5-limiting plate; 6-holds door; 7-guide rail; 8-two-way cylinder; 9-manual coupler, 10-flashing board, 11-upper door frame.
Detailed description of the invention
By reference to the accompanying drawings the specific embodiment of the present invention is described further.
As shown in Figure 1 and Figure 2, railway freight-car end device for opening/closing door, comprises hollow shaft 1, crank throw 2, crank 3, connecting rod 4, limiting plate 5, end door 6, guide rail 7, two-way cylinder 8 and manual coupler 9.A two-way cylinder 8 can control the opening and closing of two end doors 6 by driving parts, two-way cylinder 8 can be two-way cylinder or two-way hydraulic cylinder.
End door 6 is arranged at the middle part of railway freight-car end headwall, along concordant with funnel plate under doorframe, end door frame is welded on headwall, on the car body of lorry end, corresponding end door both sides arrange guide rail 7 parallel to each other, guide rail 7 top arrange can opposite rail rotate hollow shaft 1, one end of its vertical crank throw 2 relatively is fixedly connected with in the middle part of hollow shaft 1, the other end of crank throw 2 connects two-way cylinder push rod, two-way cylinder 8 is installed on car body, two symmetrical suite handles 3 and connecting rod 4 are installed in the position of hollow shaft 1 corresponding end door 6, crank 3 welds with hollow shaft 1, crank 3 and connecting rod 4 upper end, connecting rod 4 lower end adopts round pin to be connected with end door, two-way cylinder 8 drives crank, crank handle turns connecting rod, connecting rod band moved end door, end door is limited by guide rail, upper and lower vertical sliding motion.
Manual coupler 9 is welded at described hollow shaft 1 two ends respectively, and described manual coupler 9 arranges some four square holes at circumferencial direction, and end inner circumferential is four square holes, and periphery is square.
Connecting rod 4 upper end arranges limiting plate 5, limiting plate 5 bottom upwards bends, welded top on crank 3, closing when holding door when putting in place, correcting under limiting plate and blocking connecting rod, restriction crank and connecting rod overexercise, by connecting rod and end thresholding built in fastening position.When upwards opening end door, limiting plate upwards rotates with crank, and do not recur position-limiting action.
End door 6 top outer has upper door frame 11, and upper door frame 11 top is V-shaped groove structure, and end door 6 top installs flashing board 10 additional, and flashing board 10 extends downwardly in groove along V-shaped groove, and the position of the corresponding V-shaped groove of guide rail 7 has leaking hole.Rainwater is pooled in the V-shaped groove of upper door frame 11 along flashing board 10, then is discharged by the leaking hole that guide rail 7 is arranged.Prevent rain leakage to lorry inside.
When two-way cylinder 8 is released, the crank throw 2 be attached thereto upwards rotates, and drive hollow shaft 1 to rotate, hollow shaft 1 is rotated and driven crank 3 upwards to rotate, and crank 3, by drivening rod 4, makes end door 6 open along guide rail 7 upward sliding.
When two-way cylinder 8 is retracted, action is just in time contrary, and now, end door 6 is closed along guide rail 7 slide downward.The koji that is limited handle 3 and connecting rod 4 overexercise, be welded on the upper end of limiting plate 5 on crank 3, and connecting rod 4 is blocked in the lower end of limiting plate 5, and connecting rod 4 and end door 6 are limited in fastening position.
Break down for preventing two-way cylinder temporarily and affect the opening and closing of end door, welded manual coupler 9 respectively in two ends of hollow shaft 1, manual coupler 9 machined four square holes at circumferencial direction, all machined four square holes inside and outside end.When needs manual opening and closing end door, operating personnel can stand in any side of lorry, use crowbar or special cubic wrench to start movement connector and hollow shaft 1 is rotated, drive crank 3 and connecting rod 4, make end door 6 opening and closing.
