Brake air cylinder

Abstract

The invention discloses a brake air cylinder which comprises a supporting base, a protecting shell and a brake air cylinder body. The left side of the top of the supporting base is fixedly connected with the bottom of the protecting shell through bolts. A telescoping plate is connected to the right side of the protecting shell in a sliding manner. A connecting plate is fixedly connected with the right side of the telescoping plate. The outer surface of the connecting plate is fixedly connected with the left side of the brake air cylinder body through bolts. The invention relates to the technical field of air cylinders. According to the brake air cylinder, the position of the brake air cylinder can be moved, the situation that a piston rod telescopes too long is avoided, meanwhile, the brake air cylinder is treated elastically in a damping manner, thus the situation that due to the fact that inertia force is too large, the piston rod is dragged in a forced manner is avoided, and the problems that when the piston rod telescopes to the longer position, if the pressurizing force degree is large, due to long-time use, the piston rod deforms easily, when a piston of the air cylinder moves to the tail end of the journey, if certain inertia exists in loads, the air cylinder is dragged, and safety accidents are caused easily can be solved.

Description

technical field [0001] The invention relates to the technical field of cylinders, in particular to a brake cylinder. Background technique [0002] The cylinder is composed of a cylinder barrel, an end cover, a piston, a piston rod and a seal, etc. When the compressed air is input from the rodless chamber, the rod chamber is exhausted, and the pressure difference between the two chambers of the cylinder acts on the piston to form a force Push the piston to move, so that the piston rod extends. When the rod cavity is inhaled and the rodless cavity is exhausted, the piston rod is retracted. If the rod cavity and the rodless cavity are alternately sucked and exhausted, the piston realizes reciprocating linear motion , a cylindrical metal part in which the piston performs linear reciprocating motion in the cylinder. The air expands in the engine cylinder to convert heat energy into mechanical energy; the gas is compressed by the piston in the compressor cylinder to increase the p...

Problems solved by technology

[0004] Aiming at the deficiencies of the prior art, the present invention provides a brake cylinder, which solves the problem that when the piston rod of the existing brake cylinder is stretched to a longer position, if the pressure of the pressure is large, the piston will easily be caused by long-term use. The middle part of the rod is deformed. At the same time, when the cylinder piston moves to the end of the stroke, if the load has a certain inertia, it will drag the cylinder, which is likely to cause safety accidents.
