The working principle of the utility model is that after the compressed air injected into the driving air bag reaches the rated air pressure, the piston drives the ejector rod to move leftwards, so that the brake block holds the brake disc; after the gas is cut off, the piston resets under reset spring's effect, and the ejector pin resets right, makes the brake pads break away from the brake disc, through the equidistance device that moves back, can realize the equivalent back-off adjustment of brake pads according to the difference of brake pads wearing and tearing volume or stopper body mounted position, through the position of adjusting nut manual accommodate lead screw on the supporting seat. When the brake block is worn, the stroke of the ejector rod is ensured to be constant by adjusting the component, and the braking effect of the equipment during working is ensured.
The device is a safety brake device specially designed for a bogie of a coke-oven plant, is a normally open brake (namely the brake is in an open state when the air is not ventilated), is an execution element which uses air pressure to do work to stop or decelerate a moving part in machinery, and has the advantages of safety, energy conservation, simple structure, easy manufacture, low cost, simple and convenient operation, long service life and easy popularization and application.
Drawings
The present invention will be further explained with reference to the drawings and examples.
Fig. 1 is a schematic view of the overall structure of the present invention.
Fig. 2 is a schematic structural diagram of the constant-distance-setting device of the present invention.
Detailed Description
The present invention will be described more clearly with reference to the accompanying drawings and specific embodiments in the embodiments of the present invention, and the description herein is only for explaining the present invention, but not for limiting the present invention. Based on the embodiments of the present invention, any modifications, equivalent replacements, improvements, etc. made by other embodiments obtained by those skilled in the art without creative efforts should be included in the protection scope of the present invention.
Example 1
As shown in figures 1-2, the utility model provides a bogie normally open arresting gear, including bogie 1 and stopper body, the stopper body includes left brake arm 2, right brake arm 3, drive air pocket 4, ejector pin 5, when back-off device 6, reset spring 7 and brake pads 8, the middle part of left brake arm 2, right brake arm 3 all rotates through round pin axle 9 and connects on bogie 1, the lower part of left brake arm 2 and right brake arm 3 is provided with brake pads 8 relatively, drive air pocket 4 is fixed at the top of right brake arm 3, the top of left brake arm 2 is equipped with adjustment subassembly 10, the one end of ejector pin 5 is corresponding with adjustment subassembly 10, and the other end is connected with the piston in the drive air pocket 4, reset spring 7 is connected between the upper arm of left brake arm 2 and right brake arm 3, when back-off device 6 includes bottom plate 6-1, The brake device comprises a supporting seat 6-2, a screw rod 6-3 and an adjusting nut 6-4, wherein a bottom plate 6-1 is connected to a bogie 1, the supporting seat 6-2 is arranged on the bottom plate 6-1 and is positioned between the upper arms of a left brake arm 2 and a right brake arm 3, the screw rod 6-3 is in threaded connection with the supporting seat 6-2, two ends of the screw rod 6-3 are respectively abutted to the inner sides of the left brake arm 2 and the right brake arm 3, and the adjusting nut 6-4 is connected to the screw rod 6-3.
