Abstract

The invention provides a railway wagon top cover manual opening and closing device and a railway wagon. A top cover comprises a pair of cover plates arranged in parallel and capable of being opened and closed; the railway wagon top cover manual opening and closing device comprises a pair of driving mechanisms and a transmission shaft which is connected between the pair of driving mechanisms in a transmission manner; the pair of driving mechanisms is arranged at the two ends of the pair of cover plates in directions perpendicular to the contact surfaces of the pair of cover plates; each pair ofdriving mechanisms comprises screw rod supporting plates and leading screws connected with the screw rod supporting plates in a transmission manner, a pair of ejection rods and speed reducers, wherein the bottom ends of the pair of ejection rods are correspondingly and rotationally connected to the screw rod supporting plates; the top ends of the pair of ejection rods are correspondingly and rotationally connected to one cover plate; one ends of input shafts of the speed reducers are rotationally connected to transmission shafts; hand wheels are arranged at the other ends of the input shaftsof the speed reducers; and output ends of the speed reducers are connected with the leading screws. According to the railway wagon top cover manual opening and closing device, by rotating the speed reducer hand wheels at any ends of the cover plates, the cover plates can be simultaneously opened and closed so that the operation synchronism is enhanced and the reliability is high.

Description

technical field [0001] The invention belongs to the technical field of railway freight cars, and more specifically relates to a manual opening and closing device for the roof of a railway freight car and a railway freight car. Background technique [0002] Railway wagons usually have a loading port on the top, and in order to prevent dust from entering or damage to the goods during transportation, a top cover needs to be added on the top of the wagon. The top cover is usually a pair, and the top cover slides to both sides of the loading port to realize the opening and closing. In the prior art, the opening of the top cover is relatively small, and most of the top covers can only be opened and closed by pneumatic or hydraulic pressure. On the one hand It is easy to have inconsistent opening and closing speeds at both ends of the top cover, and on the other hand, it is easy to cause failure and cause the problem that the top cover cannot be opened. [0003] Therefore, a manua...
