Description
Technical field
The utility model relates to a kind of industrial hydraulic brake, hydraulic brake that particularly a kind of wind power generating set is used or title off-course brake.
Background technique
At present, industrial hydraulic brake is used very extensively, is mainly used in Large-scale Wind Turbines, normally adopts the Svendborg, Denmark break, and main feature is that Properties of Friction Materials is stable, and wear rate is low, and restraint coefficient is high.But the existing apparatus unreasonable structure, brake block is installed on the braking clamp body through groove structure, and brake block is positioned at it, the inconvenience loading and unloading, and friction plate belongs to easily damaged parts, changes frequently, loads and unloads loaded down with trivial details; Do not have resetting means in the device in addition, behind the braking brake, brake block resets slowly, has quickened the wear extent of brake block to a certain extent.
Summary of the invention
The off-course brake that a kind of wind power generating set that the utility model provides is used has solved existing apparatus unreasonable structure and the brake block technical problem slowly that resets.
The utility model solves above technical problem through following technological scheme:
The off-course brake that a kind of wind power generating set is used; Comprise substrate; Being set with afterbody on the substrate through braking clamp body and following braking clamp body on being fixedly connected that bolt links together, in the head of last braking clamp body, be provided with the brake calipers oil cylinder, in last brake calipers oil cylinder, be provided with upper piston; Be set with brake block in the end that upper piston stretches out downwards; In the head of following braking clamp body, be provided with brake calipers oil cylinder down, be provided with lower piston in the brake calipers oil cylinder down, be set with brake block down in the end that lower piston upwards stretches out; Between last brake block and following brake block, be provided with the yaw gear dish of wind power generating set; On last braking clamp body and following braking clamp body, be provided with the pouring orifice of oil cylinder, between last braking clamp body and last brake block, be provided with the brake block Returnning spring, be provided with brake block Returnning spring down down between braking clamp body and the following brake block.
Braking clamp body is provided with the brake block block on the last brake block both sides, and the following braking clamp body of following brake block both sides is provided with down the brake block block.
The brake block of the utility model is easy to loading and unloading, and it is quick to reset, and period of braking is short, generally is not more than 0.8 second, and long service life is easy to maintenance, economical and practical.

Fig. 2 is the structural relation schematic representation that the utility model cooperates with brake block;
Fig. 3 is that A-A among Fig. 2 is to sectional view.
Embodiment
The off-course brake that a kind of wind power generating set is used; Comprise substrate 14; Being set with afterbody on the substrate 14 through braking clamp body 1 and following braking clamp body 2 on being fixedly connected that bolt 4 links together, in the head of last braking clamp body 1, be provided with brake calipers oil cylinder 9, in last brake calipers oil cylinder 9, be provided with upper piston 10; Be set with brake block 11 in the end that upper piston 10 stretches out downwards; In the head of following braking clamp body 2, be provided with brake calipers oil cylinder 13 down, be provided with lower piston 12 in the brake calipers oil cylinder 13 down, be set with brake block 5 down in the end that lower piston 12 upwards stretches out; Between last brake block 11 and following brake block 5, be provided with the yaw gear dish 8 of wind power generating set; On last braking clamp body 1 and following braking clamp body 2, be provided with the pouring orifice 3 of oil cylinder, between last braking clamp body 1 and last brake block 11, be provided with brake block Returnning spring 7, be provided with brake block Returnning spring down down between braking clamp body 2 and the following brake block 5.
Braking clamp body 1 is provided with the brake block block on last brake block 11 both sides, and the following braking clamp body 2 of following brake block 5 both sides is provided with down brake block block 6.
Because the mating face of brake block is the plane, and block is arranged about brake block, realize accurate positioning, during the loading and unloading brake block, it is promptly replaceable, easy to loading and unloading, easy and simple to handle only need to lay down block, saves time.Braking, declutch, it is quick to reset, and detent torque range is big.
Break at first takes out the sealing plug in the pouring orifice in working procedure, connects break design oil pressure, after pressure oil gets into the oil pocket of oil cylinder, promotes piston and outwards moves, thereby promote upper and lower brake block, with brake disc 8 contact frictions, produces braking; When declutching, only need release oil pressure, the resetting means auxiliary reset gets final product.
Braking effect and braking moment have direct relation, and braking moment is main relevant with Properties of Friction Materials, oil pressure size, therefore as long as assurance oil pressure, seal ring, Properties of Friction Materials are stablized and just can be guaranteed the superior of braking effect.Between the general 0-16Mpa of break design work oil pressure; Organic composite friction material dynamic friction coefficient 0.4 ± 0.05, static friction coefficient 0.35-0.45, maximum service pressure 4N/mm
2, operating temperature is not more than 250 ℃; Sintered friction material dynamic friction coefficient 0.35 ± 0.05, static friction coefficient 0.35-0.4, maximum service pressure 4N/mm
2, operating temperature is not more than 700 ℃.
