Embodiment Construction

[0024] The specific embodiment of the present invention will be further described in conjunction with the accompanying drawings.

[0025] 1. Change the structure and forming method of the outer cylinder 6 and the middle cylinder 5, and change the casting into a weldment.

[0026] The outer cylinder 6 is changed from the original one-piece casting to be processed after assembly welding of parts such as ear seat 6.1, upper flange 6.2, reinforcement sleeve 6.3, outer cylinder body 6.4, air pipe 6.5 and base 6.6. In addition, the outer cylinder body 6.4 is welded by plate rings into a cylindrical shape; the middle cylinder 5 is also changed from the original one-piece casting to the outer piston cup fixing ring 5.6, the inner cylinder barrel 5.5, the inner cylinder barrel cover 5.4, and the air release device 5.3, support plate 5.2, guide sleeve 5.1 and other components are processed after assembly and welding. And the inner cylinder barrel 5.5 is welded into a cylindrical shape ...

Abstract

The invention belongs to the technical field of rail wagons, and particularly discloses a tilting air cylinder, which solves the problems of difficulty in machining, inconvenience of mounting, unsmooth work process, relatively lower air pressure bearing capacity in work, a plurality of casting defects of castings, and the like of the conventional tilting air cylinder of an automatic dumping vehicle. In the tilting air cylinder, an outer cylinder and a middle cylinder are both formed by assembling and welding independently-molded components; an outer cylinder body of the outer cylinder has a tubular structure formed by coiling and welding a board; an inner cylinder barrel of the middle cylinder also has a tubular structure formed by coiling and welding the board; a lug is provided with a gas passage; one end of the gas passage is connected with a main air pipe, and the other end of the gas passage is connected with an inlet pipe of the outer cylinder body; and the lower end of the inlet pipe is communicated with an air inlet at the bottom of the outer cylinder body. The tilting air cylinder has the advantages of reducing the rejection rate and the production cost, avoiding the casting defects of the original castings, reducing dead weight, improving the appearance quality, eliminating own swing and avoiding further faults.

Description

technical field [0001] The invention belongs to the technical field of railway wagons, and in particular relates to a tipping air cylinder. Background technique [0002] The current problems of the tilting air cylinders commonly installed on railway self-rollover cars are as follows: [0003] 1. Its outer cylinder body and outer piston are cast iron. Due to the large dimensions of the outer cylinder and the outer piston, there are extremely high requirements for its casting process. Even so, the yield rate is still not high; some castings seem to be good before processing, but many defects such as trachoma, shrinkage porosity, shrinkage cavity, and inclusion of ballast are found during processing. This results in a very high scrap rate; sometimes after the processing is completed, although the inspection is qualified, in the process of using after loading, due to the increase of wind pressure, there are still faults such as air flow and air leakage due to the congenital de...
