Description

Height position adjustment mechanism of train sleeper deck

technical field

The invention belongs to transportation machinery, and mainly relates to a mechanism for adjusting the height position of a train sleeper deck.

Background technique

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 transporting passengers and meet the needs of migrant workers to purchase tickets, many hard sleeper cars are operated as hard seat cars, which are less convenient and comfortable to use.

Contents of the invention

The purpose of the present invention is to solve the above-mentioned problems in the prior art and to design and provide a mechanism for adjusting the height and position of the berth of a train sleeper in combination with the actual needs of passenger transportation, so as to achieve the purposes of strong applicability, simple adjustment and convenient use.

The purpose of the present invention is achieved in this way: the train sleeper deck height position adjustment mechanism includes an upper deck, a middle deck, a lower deck, and inner partitions and end baffles arranged on the inner sides and outer ends of the upper, middle, and lower decks , the left and right sides of the inner partition are respectively vertically fixed to the guide rails, and the upper slider, the middle slider and the lower slider can be moved up and down on the guide rails on both sides from top to bottom. The upper plank, middle plank and lower plank are respectively fixed on the upper slide, middle slide and lower slide respectively; The upper lead screw and the lower lead screw are rotatably installed, the upper screw nut and the lower screw nut are screwed and installed on the upper lead screw and the lower lead screw respectively, the upper screw nut is fixedly integrated with the middle deck, the lower screw nut The nut and the lower deck are fixedly integrated, and the upper and lower passive bevel gears are respectively fixed on the ends of the upper screw and the lower screw. Active bevel gear, the upper active bevel gear meshes with the upper passive bevel gear, and the lower active bevel gear meshes with the lower passive bevel gear; reversing rollers are rotatably equipped on the left and right upper parts of the inner partition respectively, A capstan wheel is rotatably equipped on the upper part of one side of the inner partition, and the stay rope is slidably arranged on the lower part of the upper deck. The stay rope is wound on the left and right reversing rollers, and one end of the stay It is connected with the capstan wheel, and its other end is fixedly connected to the inner partition.

The invention can adjust the height of each layer of decking according to the consultation opinions of passengers, and change the distance between each layer of decking, so as to adapt to and meet the comfort and convenience of passengers in different conditions. It has novel and reasonable structure, adjustable operation Simple and convenient, realize stepless adjustment, strong applicability and reliable use.

detailed description

Embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. A mechanism for adjusting the height position of sleeper decks in trains, comprising upper decks 4, middle decks 7, lower decks 9, and inner partitions 1 and end stops arranged on the inner sides and outer ends of the upper, middle, and lower decks 4, 7, and 9 Plate 3, on the left and right sides of the inner partition 1, respectively stand on the fixed guide rails 17, on the guide rails 17 on both sides, the upper slider 18 and the middle slider can be moved up and down sequentially from top to bottom. 16 and the lower slider 12, the upper deck 4, the middle deck 7 and the lower deck 9 are respectively fixed on the upper slider 18, the middle slider 16 and the lower slider 12 in turn; 1. The upper lead screw 14 and the lower lead screw 10 are rotatably installed vertically from top to bottom between the right side guide rails 17, and the upper screw nut 15 and the lower screw nut 11 are screwed and installed on the upper screw screw 14 and the lower screw nut 11 respectively. On the lead screw 10, the upper screw nut 15 is fixedly integrated with the middle deck 7, and the lower screw nut 11 is fixedly integrated with the lower deck 9, on the end of one side of the upper screw 14 and the lower screw 10 The upper passive bevel gear 6 and the lower passive bevel gear 13 are fixed respectively, and the upper active bevel gear 5 and the lower active bevel gear 8 are rotatably installed on the inner partition 1. The upper active bevel gear 5 and the upper passive bevel gear 6 meshing, the lower driving bevel gear 8 meshes with the lower passive bevel gear 13; the reversing rollers 2 are rotatably equipped on the left and right upper parts of the inner partition 1 respectively, and are rotatable on the upper part of one side of the inner partition 1 The capstan wheel 19 is equipped with the ground, and the stay rope 20 is slidably arranged on the lower part of the upper plank 4. The stay rope 20 is wrapped around the reversing rollers 2 on the left and right sides, and one end thereof is connected with the capstan wheel 19. , the other end of which is fixedly connected to the inner partition 1.

When adjusting the height position of the upper plank 4, rotate the capstan wheel 19, and the stay cord 20 is gradually wound on the capstan wheel 19 or released from the capstan wheel 19. The height position adjustment on the inner partition 1 is completed under the control of the guide rail 17. When the height position of the middle deck 7 is adjusted, the upper active bevel gear 5 is rotated, and the upper screw 14 is driven to rotate through the upper passive bevel gear 6, so that the upper screw nut 15 moves up and down on the upper screw 14, and the middle slider 16, guide rail 17 under the control, make the middle plank 7 complete the height position adjustment on the inner dividing plate 1. The height position adjustment method of lower plank 9 is identical with the height position adjustment method of middle plank 7.
