Upper raised floor of a double-deck transport automobile rail vehicle and method of use thereof

Abstract

The invention relates to an upper-layer movable floor of a double-layer automobile-transporting railway vehicle and a using method thereof. The upper-layer movable floor is characterized in that the floor comprises a composite floor body, supports and an elastic lockpin, the composite floor body is located on the two supports placed in parallel, and the elastic lockpin is used for locking the composite floor body and the supports; the composite floor body comprises a steel frame, a main floor body, a steel panel and connecting rivets, wherein the main floor body is arranged on the upper portion of the steel frame, the steel panel is arranged on the upper portion of the main floor body, and the steel frame, the main floor body and the steel panel are connected through the multiple connecting rivets; each supporting comprises a rib plate, a shoulder belt, shaft sleeves and torsion springs, wherein the rib plate is of a structure similar to a right triangle, the hypotenuse of the right triangle is an inward-concave arc, the shoulder belt is fixedly arranged on one right-angle side of the rib plate, the two shaft sleeves are fixedly arranged at the two ends of the other right-angle side of the rib plate respectively, one shaft sleeve penetrates through one end of the shoulder belt, and the two torsion springs are correspondingly arranged on the inner end faces of the two shaft sleeves respectively. The upper-layer movable floor can be widely used on the double-layer automobile-transporting railway vehicles.

Description

technical field [0001] The invention relates to a raised floor of a railway vehicle and a method for using the same, in particular to an upper raised floor of a railway vehicle for double-deck transport vehicles and a method for using the same. Background technique [0002] In order to meet the railway transportation demand of domestic automobile manufacturers for zero-kilometer sales of new cars, my country's railways have developed special transport vehicles such as SQ1 and JSQ5. An upper floor frame is arranged at a proper height, and the interior space of the car is divided into upper and lower layers. The cars of the lower layer are loaded on the floor of the lower frame of the car body, and the cars of the upper layer are loaded on the floor of the upper frame. [0003] The upper chassis of SQ1, JSQ5 and other railway double-deck transport vehicles adopts an integral structure. The upper chassis is completely fixed or can only be lifted within a small range. Since the u...

Problems solved by technology

[0003] The upper chassis of SQ1, JSQ5 and other railway double-deck transport vehicles adopts an integral structure. The upper chassis is completely fixed or can only be lifted within a small range. Since the upper chassis divides the height space in the car into upper and lower layers, restrictions The height of each layer of space, so these vehicles are limited when transporting cars or general goods with a large height; The structure adopts an all-steel structure, which is heavy and difficult to turn over
