Abstract
The invention relates to an elevator disc brake with the locking function, and the elevator disc brake solves the problems that an existing elevator disc brake is not reasonable in structural design, and due to the fact that a gap among brakes is changed easily, the braking effect is affected. The elevator disc brake comprises brake blocks arranged on the two sides of a brake disc, the lower sides of the centers of the brake blocks are fixedly connected with a pull rod, a sliding sleeve is fixed on the outer side of the pull rod, the pull rod is sleeved with a disc spring located on the inner side of the sliding sleeve, the lower end of the disc spring is provided with a pressing ring, the lower end of the pressing ring is provided with an oil cylinder, a machine cover is fixed at the bottom of the oil cylinder, a piston is arranged on the inner side of the oil cylinder, a sleeve is fixed inside the piston, a connecting screw fixedly connected with the pull rod is fixed inside the sleeve, a support is arranged on the outer side of the oil cylinder, a support is arranged on the outer side of the oil cylinder, the sliding sleeve slides up and down in the support, a flange-shaped adjusting sleeve is arranged between the support and the oil cylinder, the adjusting sleeve is in threaded connection with the inner wall of the lower portion of the support, the top end of the adjusting sleeve makes surface contact with a step on the upper portion of the oil cylinder, an inner hexagonal screw is fixed between the bottom end face of the adjusting sleeve and the support, and the oil cylinder is provided with a plug screw and a bleeder screw. The braking force of an elevator is guaranteed through the elevator disc brake.
Description
Technical field
The present invention relates to colliery downhole equipment, relate in particular to the component part of gig, be specially a kind of gig dish brake with blocking function.
Background technology
Brake for elevator system, is to push belleville spring by hydraulic pressure, realizes the switching of disk type gate, and disk type gate is opened in the situation that give pressing, and after opening, the gap of itself and brake disc is one of topmost factor of regulating brake force.Adjusting brake clearance realizes by degree of tightness disk type gate screw thread.Existing dish brake is because structure design is reasonable not, affect braking effect, and disk type gate in use, owing to having certain impact to pressure and pressure release, add the reasons such as equipment operational shock, can cause adjusting the screw thread existence activity of brake clearance, by directly causing the variation of brake clearance, further affect braking effect.
Summary of the invention
The present invention easily changes and affects the problem of braking effect in order to solve the unreasonable and brake clearance of existing gig dish brake structure design, and a kind of gig dish brake with blocking function is provided.
The present invention adopts following technical scheme to realize: the gig dish brake with blocking function, comprise the slipper that is arranged on brake disc both sides, the center downside of slipper is fixed with pull bar, pull bar outside is fixed with sliding sleeve, and on pull bar, cover has the dish spring that is positioned at sliding sleeve inner side, dish spring lower end is provided with pressure ring, pressure ring lower end is provided with oil cylinder, oil cylinder bottom is fixed with cover, oil cylinder inner side is provided with piston, in piston, be fixed with sleeve, in sleeve, be fixed with the attaching screw fixing with pull bar, oil cylinder arranged outside support, slide in support and slide up and down, between support and oil cylinder, be provided with flange-like regulating sleeve, regulating sleeve is threaded with support lower inner wall, the top of regulating sleeve contacts with oil cylinder top cascaded surface, between the bottom face of regulating sleeve and support, be fixed with socket head cap screw, on oil cylinder, be provided with plug screw and air bleed screw.
During the braking of gig dish brake, the precompressed compression of dish spring forces sliding sleeve to move up, and sliding sleeve drives pull bar, attaching screw, sleeve and piston to move up, and then promotion slipper contacts with the brake disc of reel, and produce positive pressure, form friction force and produce braking; When gig dish brake is loosening, charged pressure oil in oil cylinder chamber, piston moves down under the effect of pressure oil, drives sleeve pipe, attaching screw, pull bar and sliding sleeve to move down, and compact disc spring, makes slipper leave brake disc again, brake off power; Meanwhile, the setting of socket head cap screw and regulating sleeve, the disk type gate screw thread of placing between oil cylinder and support is loosening, finally guaranteed that brake clearance can not change because non-artificial reason exists, overcome the unreasonable and brake clearance of existing gig dish brake structure design and easily changed and affect the problem of braking effect.
Reasonable in design of the present invention is reliable, and the disk type gate gap making is consistent, and disk type gate brake shoe and the unnecessary wearing and tearing of brake disc can, because of non-artificial former change, not avoided in disk type gate brake clearance; And the structure design of dish brake is guaranteed elevation scheme power, guaranteed the safety and steady operation of gig, reduced the Maintenance and Repair amount of disk type gate simultaneously.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
In figure: 1-slipper, 2-pull bar, 3-sliding sleeve, 4-dish spring, 5-pressure ring, 6-oil cylinder, 7-cover, 8-piston, 9-sleeve, 10-attaching screw, 11-support, 12-regulating sleeve, 13-socket head cap screw, 14-plug screw, 15-air bleed screw.
The specific embodiment
The gig dish brake with blocking function, comprise the slipper 1 that is arranged on brake disc both sides, the center downside of slipper 1 is fixed with pull bar 2, pull bar 2 outsides are fixed with sliding sleeve 3, and on pull bar 2, cover has the dish spring 4 that is positioned at sliding sleeve 3 inner sides, dish spring 4 lower ends are provided with pressure ring 5, pressure ring 5 lower ends are provided with oil cylinder 6, oil cylinder 6 bottoms are fixed with cover 7, oil cylinder 6 inner sides are provided with piston 8, in piston 8, be fixed with sleeve 9, in sleeve 9, be fixed with the attaching screw 10 fixing with pull bar 2, oil cylinder 6 arranged outside supports 11, sliding sleeve 3 slides up and down in support 11, between support 11 and oil cylinder 6, be provided with flange-like regulating sleeve 12, regulating sleeve 12 is threaded with support 11 lower inner wall, the top of regulating sleeve 12 contacts with oil cylinder 6 top cascaded surfaces, between the bottom face of regulating sleeve 12 and support 11, be fixed with socket head cap screw 13, on oil cylinder 6, be provided with plug screw 14 and air bleed screw 15.
In specific implementation process, slipper 1 is entrenched in the dovetail furrow of sliding sleeve 3, and is fixed with pressing plate, screw; Between support 11 and sliding sleeve 3, be provided with key, anti-anti-skid sheath rotates; Air bleed screw 15 can be discharged the gas that retains in oil cylinder 6, to guarantee that dish brake can work neatly; Dish brake within the scope of sealing member allows leakage, may have trace in let out, though internal drainage can play lubricated sliding sleeve 3 and support 11, the time, when longer, internal drainage may retain too much, therefore should regularly from plug screw 14, discharge internal drainage liquid.
