Disc type passenger train brake tube box

Abstract

The invention discloses a disc type passenger train brake tube box which is characterized in that a disc type brake tube box is mounting basis of all brake components; all brake components of one passenger train are contained in the tube box; in order to save the space, a train tube longer than 20m in the passenger train is replaced by a disc type brake tube coil of which the diameter is 1m and the total length is equal to that of the original train tube, and the diameter of a tube of the train tube coil in the tube box is equal to that of the train tube; in order to conveniently connect and disassemble tube boxes, clamp sleeve type tube connectors identical to those of a practical train are adopted, four universal casters are arranged below the tube box so that the tube boxes can be conveniently connected and moved when being assembled, and the casters also play roles of positioning and supporting the tube boxes; and in order to ensure relative fixation of positions of the tube boxes in brake tests, the casters can be locked by pedals, and when the tube boxes are moved, the pedals can be released, and thus the casters can be unlocked.

Description

technical field [0001] The design of the present invention is a brake tube box for a disc passenger car. When carrying out train simulation braking tests in the laboratory, due to the long train marshalling, there are two traditional methods: one is to arrange the train tubes in a serpentine section by section according to the actual length of the passenger train tubes, and then connect the sections by pipe joints. The train tube is long and heavy, and the compressed air in the train tube must be sealed, and the position of the train tube is not allowed to move during braking. Therefore, the train tubes are all fixedly installed, and it is not convenient to connect and disassemble any train tubes; It adopts the pipe box structure arranged in a snake line. Since the length of the pipe box is much smaller than the length of the train pipe, it needs more than 20 round trips in a snake, and the number of round trips is relatively large. In addition, the space of the pipe box is li...

Problems solved by technology

[0005] The beneficial effects of the design of the present invention are: 1. Completely solve the problem of limited laboratory space, large flow resistance, and connection and disassembly between any train tube boxes; 2. Easy to use: the structure is simple, safe and reliable; 3. It completely solves the inconvenient problem of random marshalling among locomotives, passenger cars and trucks: the tube boxes are connected with ferrule joints through hoses, which are very convenient to connect and disassemble, and the movement of the tube boxes is through the 4 tubes below the tube boxes. It is realized by the rolling of one universal caster, therefore, the pipe box can be quickly and conveniently organized in any group as required
