Narrate its working principle of the utility model and operating method in conjunction with the accompanying drawings below by embodiment:
1, need not under the compensation situation in normal working:
At first piston (3) is lifted supreme cylinder block (12) top.Because being positioned at four gussets (17) top, moving cylinder (4) remains static, under the effect of its deadweight, valve rod (11) contacts with impeller (6) axis, make valve (5) be opening state, so when lifting piston (3), hydraulic oil can be smoothly entered in the grease chamber (10) that piston (3) and last cylinder block (12) form by valve (5), thereby has guaranteed freely lifting of piston (3).
Then, starting electrical machinery (9) power supply.When impeller rotation produces upwards thrust and promotes moving cylinder (4) and rise, push rod (1) is subjected to the active force of brake spring (22) to produce downwards an active force with the thrust opposite sign but equal magnitude, because cylinder block (12) diameter of bore is less than following cylinder block (13) on the moving cylinder, so valve (5) upper-end surface is subjected to the unit pressure of push rod (1) and is subjected to impeller (6) specific thrust greater than the lower end surface, therefore valve (5) can be closed at once, thereby has guaranteed that thrust of impeller drives moving cylinder (4) and moves upward together with piston (3) and push rod (1).Like this, break just under effect of the present utility model, is opened brake shoe (25) by the continuous action of connecting rod (21), brake arm (23), finishes the mechanical opening program of break this moment.Work as powered-down, impeller (6) is when stopping operating, the upwards thrust of impeller (6) disappears at once, at this moment, break is because the effect of spring (22), and driving push rod (1) on the one hand, that cylinder (4) is moved down is multiple to original position, and brake shoe (25) also cuts out simultaneously on the other hand, at this moment, just finished the mechanical braking program of break.
The working stroke of its moving cylinder (4) of the utility model is to remain constant by upper cylinder (2) and oil-deflecting element (8) location.
2, the automatic compensation work principle of the utility model:
When brake block friction plate (26) wearing and tearing make brake lining (26) increase with Brake drum (24) gap, then brake arm (23) can make brake lining (26) produce a displacement that equals brake lining (26) wear extent to Brake drum (24) center under the effect of spring (22) at any time, push rod this moment (1) is also discharged hydraulic oil by valve (5) at the effect lower compression piston (3) of spring (22) simultaneously and is produced a displacement downwards in moving cylinder (4), till brake is fastening.Like this, break can be proceeded the opening and closing braking work of machinery again under the new displacement situation of the utility model piston (3).Thereby the braking gap that has guaranteed brake lining (26) is constant.
The utility model and prior art contrast have following characteristics:
1, its automatic compensation function of the utility model is to be realized by piston (3) displacement in the cylinder block (12) on moving cylinder, thereby constant brake lining (26) gap has guaranteed that the braking ability of brake is safe and reliable.
2, the utility model is simple in structure, installation and processing is all more convenient.Motor is oil immersed type not, thereby can improve motor working life.In addition, its motor of the utility model and hydraulic oil all can be selected plain edition for use, for this machine form a complete production network and application provides convenience.
