Embodiment Construction

[0043] like figure 1 As shown, since the length of the existing self-dumping truck loading and unloading supporting facilities has been fixed, the length of the vehicle should not be changed in order to be used in conjunction with the existing facilities.

[0044] Since the maximum width of the dump truck with a load of 60t is 3280mm, the outer width of the lower part of the compartment is already close to the limit, and it is difficult to widen it. However, the maximum outer width of the top is 3164mm, and each side has a distance of 118mm from the limit, and there is a small amount of room for increase in the width direction. .

[0045] After analysis, the load of the upper side beam of the side door is small, and the section size can be reduced. In order to make full use of the lateral space, the transverse section size of the upper side beam of the side door is reduced, and the section size of the lower side beam with large load is increased. When the interior length of t...

Abstract

The invention discloses a railway side dump car, which is characterized in that the upper cross section of each side door of the side dump car is small, the lower cross section of each side door of the side dump car is large, and the upper cross section is determined by calculation according to the minimum impact load of goods on the side doors. The camber angle of each side door is increased by 8-10 degrees. The height of each side door is increased, and the maximum relative distance between the tops of the two side doors is within the outer width of the lower part of a carriage. According to the railway side dump car disclosed by the invention, through the improvement on the structure of the carriage, the limit is fully utilized, and the lateral dimension of the carriage is increased; and on the premise of meeting the antidumping safety requirement of dumping operation, the internal height of the carriage is increased. The capacity of the carriage is increased through the combination of the modes, the full load need in transporting main trend granular goods is met, and the economic benefit of transportation is improved.

Description

technical field [0001] The invention relates to a railway self-rollover car. Background technique [0002] The railway self-dumping car is a special vehicle that combines unloading equipment and vehicle structure. It is suitable for transporting bulk goods such as ore, gravel, coal, and building materials on the railway. special vehicles. The car body part of the railway self-dumping car is mainly composed of two parts: the chassis and the carriage. The carriage is directly used for loading materials. Through the tipping transmission device installed on the chassis, usually a cylinder or oil cylinder, the carriage is driven to the side according to the requirements of the working conditions. When a certain side is overturned, the side door is controlled to open gradually during the overturning process of the compartment through the side door opening and closing device installed on the compartment. At present, the heavy-duty self-dumping car has been improved and perfected ...
