Abstract
The utility model provides a normally open adjustable air-powered hydraulic brake. The brake is composed of a braking support seat, a braking oil cylinder and a brake shoe; the braking oil cylinder is fixed on the braking support seat, a piston rod in the braking oil cylinder is connected with the brake shoe located under the braking support seat, an adjusting bolt capable of adjusting a displacement range of a piston is arranged on the body of the braking oil cylinder, and one end of the adjusting bolt is in contact and connected with the piston in the braking oil cylinder by use of a buffer element; guide rods are symmetrically arranged on the brake shoe, guide holes matched with the guide rods are formed in the braking support seat, and the guide holes penetrate through both ends. The normally open adjustable air-powered hydraulic brake has the advantages that the braking pressure is always kept above the working pressure and the deviation phenomena caused by uneven braking are reduced, the working time of adjusting a gap is saved and the labor intensity is reduced, and even braking effect is guaranteed conveniently, quickly and effectively, and whether the brake shoe needs to be replaced can be known by virtue of indirect convenient observation.
Description
Technical field
The utility model relates to a kind of railway transport mechanical brake equipment, especially a kind of open in usual can regulating the qi flowing in the channels power-assisted hydraulic brake.
Background technique
Prior art situation: break is exactly so-called brake, object is to make mechanical motion part stop or slowing down, sometimes also with making adjustments or the movement velocity of limting mechanism or machine.For reducing retarding torque, dwindle brake dimensions, conventionally break is contained on the high speed shaft of mechanism, or turns on the input shaft of retarder.Big machinery should be arranged in lower velocity shaft or spool shaft in order to improve its Security, in case in driving mechanism the falling of article when off-axis;
Structure: break is mainly made up of Der Bremssattel, brake cylinder and brake shoe;
Working principle: break divides by working state, can be divided into open in usual and Normally closed type, and break open in usual is often in the state of declutching; Break applies certain frictional force by liquid-driving brake shoe to Brake drum, makes the mechanism of motion slow down, stop or keeping its low-speed running; Normally closed type is just in time contrary, needs outer power to make break declutch to ensure mechanical motion;
Shortcoming: the difficult problem that break open in usual faces is the wearing and tearing along with brake shoe, needs often to regulate the gap between brake shoe and wheel.Along with the increase in gap, cause brake cylinder cavity volume to increase, thereby cause pressure decreased, so that the situation of braking failure occurs; And for one group of break, the wearing and tearing of its single brake assemblies are not quite similar, it adjusts very trouble, needs back and forth constantly debugging measurement clearance.Again, for confined space, also need often to observe and detect the abrasion condition of brake shoe, to determine whether it needs to change.
Summary of the invention
The utility model provide a kind of open in usual can regulating the qi flowing in the channels power-assisted hydraulic brake, be mainly the increase of avoiding along with brake clearance, cause brake cylinder cavity volume to increase, thereby cause pressure decreased, so that the situation of braking failure occurs; And solve asynchronous, the inhomogeneous problem of all brake groups brakings.
In order to solve the problems of the technologies described above, the technical solution of the utility model is: open in usual can regulating the qi flowing in the channels power-assisted hydraulic brake, break is mainly made up of Der Bremssattel, brake cylinder and brake shoe, brake cylinder is fixed on Der Bremssattel, piston rod in brake cylinder is connected with the brake shoe that is positioned at Der Bremssattel below, it is characterized in that: the cylinder body of brake cylinder is provided with the adjusting bolt of energy regulating piston displacement range, adjusting bolt one end is connected with the piston contact in brake cylinder by buffer body; On described brake shoe, be arranged with guide rod, Der Bremssattel is provided with the pilot hole coordinating with guide rod, and the two ends of pilot hole connect.
To the further restriction of technique scheme, the cylinder body of described brake cylinder is connected with adjusting bolt by nut, is in order to reduce production costs like this.
To the further improvement of technique scheme, described buffer body is made up of rubber or polyurethane material.
Beneficial effect: in the time of needs auto-compensation brake shoe and wheel wearing clearance, pressure need be dropped under working pressure, can adjust brake clearance; By rotation adjusting bolt, the displacement range of restriction main piston, thus the variation that ensures volume is in safety range; By rotation adjusting bolt, promote brake shoe and contact with Brake drum, then by the identical angle of unified adjusting bolt convolution, thereby ensure that each group brake clearance is basically identical; In the time that guide rod end is concordant with the upper plane in Der Bremssattel bottom, represent that this brake block needs to change; The utlity model has following advantage: 1., always keep retardation pressure on working pressure, and reduce because braking the inhomogeneous deviation phenomenon causing; 2., save and regulate the interval work time and reduce labor intensity, and convenient, fast, effectively ensure braking effect evenly; 3., just knownly whether need to change brake shoe by indirectly observing easily.
