Embodiment Construction
[0014] The specific embodiment of the present invention will be further described in conjunction with the accompanying drawings.
[0015] Such as figure 1 , figure 2 As shown, the opening and closing device for the end door of a railway freight car includes a hollow shaft 1 , a crank 2 , a crank 3 , a connecting rod 4 , a limit plate 5 , an end door 6 , a guide rail 7 , a bidirectional cylinder 8 and a manual connector 9 . A two-way cylinder 8 can control the opening and closing of the two end doors 6 through transmission parts, and the two-way cylinder 8 can be a two-way air cylinder or a two-way hydraulic cylinder.
[0016] The end door 6 is set in the middle of the end wall of the railway freight car, the lower edge of the door frame is flush with the funnel plate, the end door frame is welded to the end wall, and the guide rails 7 parallel to each other are arranged on the two sides of the corresponding end door on the end body of the freight car. The top of the guide r...

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 [0001] The invention belongs to the technical field of railway freight cars, and in particular relates to an opening and closing device for an end door of a railway freight car. Background technique [0002] Generally, there is no end door at the end of the railway freight car, even if there is, it can only be opened and closed manually, and there is no end door opened and closed by air pressure or hydraulic pressure. Contents of the invention [0003] In order to solve the problem that the existing railway freight car has no end door or the end door can only be opened and closed manually, the present invention provides an opening and closing device for the end door of the railway freight car. [0004] The present invention adopts following technical scheme to realize: [0005] An opening and closing device for the end door of a railway freight car. The end door is arranged at the end of the railway freight car. On the car body at the end of the freight ca...
