Height position regulating mechanism for bed boards of berth in train

Abstract

The invention discloses a height position regulating mechanism for the bed boards of berths in a train, and belongs to machinery for traffic. guide rails are respectively fixedly arranged on left and right side parts of an inner clapboard; upper, middle and lower slide blocks are arranged on the left and right guide rails; upper, middle and lower bed boards are respectively fixedly arranged on the upper, middle and lower slide blocks in sequence; an upper lead screw with an upper driven bevel gear and an upper nut, and a lower lead screw with a lower driven bevel gear and a lower nut are rotationally arranged on the inner clapboard; an upper driving bevel gear and a lower driving bevel gear assembled on the inner clapboard are respectively meshed with the upper driven bevel gear and the lower driven bevel gear; the upper nut and the lower nut are respectively fixed with the middle and lower bed boards; the upper parts of the left and right sides of the inner clapboard are provided with reversing rolling wheels; a pulling rope is configured on the downside part of the upper bed board in a sliding manner; one end of the pulling rope is connected with a winch drum, while the other end is fixedly connected with the inner clapboard; The mechanism is novel and reasonable in structure, simple and convenient for adjustment, and high in applicability.

Description

technical field [0001] The invention belongs to transportation machinery, and mainly relates to a mechanism for adjusting the height position of a train sleeper deck. Background technique [0002] In the sleeper compartments of existing trains, no matter whether it is a hard sleeper or a soft sleeper, the height of the bed board of the sleeper cannot be adjusted. Since the soft sleeper has a two-layer structure, its height and position are still satisfactory and convenient to use, but the height of the hard sleeper cannot be adjusted. The three-layer bunk structure of adjustment just brings a lot of inconvenience to the passenger's use, even if the passenger is according to the difference of stature and the convenience of use, when reaching through negotiation can carry out the height adjustment intention between each layer of decking, also can't implement adjustment. In addition, during the Spring Festival travel period in my country, in order to improve the capacity of tra...

Problems solved by technology

[0002] In the sleeper compartments of existing trains, no matter whether it is a hard sleeper or a soft sleeper, the height of the bed board of the sleeper cannot be adjusted. Since the soft sleeper has a two-layer structure, its height and position are still satisfactory and convenient to use, but the height of the hard sleeper cannot be adjusted. The adjusted three-layer bunk structure brings a lot of inconvenience to passengers. Even if passengers reach an agreement to adjust the height of each layer of boards according to their body size and ease of use, the adjustment cannot be implemented.

In addition, during the Spring Festival travel period in our country, in order to improve the capacity of transporting passengers and meet the needs of migrant workers' ticket prices, when operating many hard sleeper cars as hard seat cars, the convenience and comfort of use are poor.
