Push-pull telescopic movable awning used for railway flatcar

Abstract

The invention discloses a push-pull telescopic movable awning used for a railway flatcar. The push-pull telescopic movable awning comprises a plurality of supports arranged in the longitudinal direction of a car body and awning cloth covering an arch supporting framework composed of the multiple supports. Pulley assemblies are arranged at the two ends of each support correspondingly. The pulley assemblies are in sliding fit with corresponding guide rails fixedly connected to upper side beams of the car. Articulating assemblies are arranged between every two adjacent supports. The multiple supports are connected together through the articulating assemblies, and push-pull telescoping of the multiple supports is driven by telescoping of the articulating assemblies. An awning cloth side wall of a push-pull telescopic structure is adopted, the opening degree of the movable side wall is large, the requirement of hoisting operation by a gantry crane is met, the awning can be suitable for loading of long and large cargos, and the awning has the characteristics of being low in self weight, simple in structure and convenient to maintain.

Description

technical field [0001] The invention belongs to the technical field of railway freight cars, and particularly relates to a push-pull telescopic movable awning for a railway flat car. Background technique [0002] At present, the side walls of the railway general-purpose boxcars are welded with thin plates and side columns to form a plate-column fixed structure. This boxcar has the following shortcomings and needs to be improved: 1. The side walls of the boxcar cannot be pushed, pulled and stretched, and cannot be adapted to the hoisting operation of the gantry crane; 2. The side walls are self-contained It is very important and needs to be installed with doors to reduce the effective load of the vehicle; 3. It is not suitable for loading long and large types of goods. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to provide a movable awning for a railway flat car in which the tarpaulin side wall of the box car can be pushed, pulled and retracted...
