Abstract
The utility model discloses lifting machine stopper, the braking that is most suitable for mine winder adopts reasonable welt structure, gets rid of the round pin axle, leans on barrel one side welt to cooperate with the form of cylinder excircle with the tang, and return means and village board thread connection department thickening adopt the blind hole. Corresponding to the prior art, the brake block is effectively fixed, the displacement of the brake shoe in the braking process is controlled, the anti-shearing capability is greatly improved, and the braking effect is satisfactory.
Description
The gig braking device that the utility model relates to is particularly useful for the braking of mine hoist, also is applicable to winch and other occasion that need brake.
Drg is the crux parts of mine hoist safe operation, and whether reliable operation has decisive meaning for security improvement to drg.Though existing drg can satisfy the requirement of braking, but there are the following problems: 1. the major part lining plate structure that transmits pressure is unreasonable, can't fix brake shoe very firmly, brake shoe has bigger moving up and down in braking procedure, sends strike note simultaneously.2. pin diameter is little in the cylindrical shell, and is built on the sand, yielding and cut off.
In view of the problem that prior art exists, the purpose of this utility model provides a kind of drg, and its lining plate structure that transmits pressure is reasonable, can overcome many shortcomings of original design, thereby realizes the failure-free braking.
The utility model gig braking device, by brake shoe, liner plate, cylindrical shell oil cylinder, piston, piston bush, bearing pin, trimming screw, dish-type spring, seal ring, compositions such as return mechanism, it is characterized in that: remove bearing pin, liner plate is the plane by brake shoe one side, match by the form of the outer garden of cylindrical shell one side plate and cylindrical shell, move up and down, improve anti-shear ability simultaneously with the restriction liner plate with seam; Garden post of core processing of liner plate, there is tapped bore at post center, garden, so that liner plate and cylindrical shell and plunger screw are linked together: blind hole is also adopted in return mechanism and the thickening of liner plate thread connection place, bolt in the return mechanism limits liner plate by the return spring hole on the support and brake shoe rotates, around the liner plate brake shoe pressing plate is housed: the other end of plunger is processed with certain tapering, so that seal ring successfully is set on the plunger.
The utility model gig braking device is best suited for the braking of mine hoist, also be applicable to winch and other occasion that need brake, prior art corresponding to this technical field, changed the structure of liner plate, actv. has been fixed brake shoe, has controlled the displacement of brake shoe in braking procedure, improved anti-shear ability greatly, through the trial-production experiment, effect is satisfied, has practicality.
Description of drawings:
Fig. 1: brake structural figure:
Fig. 2: the local figure of return mechanism.
Below in conjunction with accompanying drawing the utility model is described further:
The utility model drg, liner plate 5 is planes by brake shoe 4 one sides, by cylindrical shell 6 one sides, liner plate 5 and the cooresponding core of cylindrical shell 6 external diameters, be processed with a blind hole that matches with the cylindrical shell external diameter, liner plate 5 matches with the form of cylindrical shell 6 outer gardens with seam, moving with restriction liner plate 5 strings, improve anti-shear ability, garden post of core processing of liner plate 5, there is tapped bore at post center, garden, by plunger 12 cylindrical shell and liner plate are linked together, oil cylinder 8 is housed in the cylindrical shell, piston 10 is housed in the oil cylinder 8, piston bush 15, cup spring 16, plunger 12 matches with piston 10, and its afterbody is processed with tapering, the y-type seal ring 9 of being convenient to pack into, 11, the afterbody of plunger 12 also is equipped with trimming screw 14 and holding screw 13.Lid and fixing by bolt 17 is equipped with at the cylindrical shell rear portion, covers thoroughly stifle 18 is housed.The fixedly pressing plate 3 of brake shoe 4 is housed around the liner plate 5, and pressing plate 3 is fixing by several bolts 2.Return mechanism 1 is equipped with at the two ends of liner plate, and return mechanism is by bolt 1-2; Bearing 1-3; Spring 1-4; Nut 1-5 forms.Return mechanism and the thickening of liner plate thread connection place are also adopted blind hole 1-1.
The braking procedure of drg: pressure oil flows into oil cylinder from the P mouth, when the control system oil pressure reduces, pressure oil reduces the propelling thrust of piston 10, piston 10 is moved to the left under the elastic force effect of cup spring 16, and drive plungers 12 by trimming screw 14 and be moved to the left, plunger 12 promotes cylindrical shell 6, and the end face of cylindrical shell 6 promotes liner plate 5, and liner plate 5 promotes brake shoe 4 and is moved to the left simultaneously, brake shoe 4 contact brake discs, and to the suitable positive pressure of brake disc generation, thereby between brake shoe and brake disc, producing friction force, this power is braking force, braking oil pressure is low more, braking force is big more, and when braking oil pressure was reduced to the residual voltage value, braking force reached maxim; Process declutches: the control system oil pressure raises, pressure oil increases the propelling thrust of piston 10, piston 10 moves right under the promotion of pressure oil, compression cup spring 16, driving plunger 12 by trimming screw 14 simultaneously moves right, the pressure of 12 pairs of cylindrical shells 6 of plunger reduces, thereby is directed at 6 pairs of liner plates 5 of cylindrical shell, 5 pairs of brake shoes 4 of liner plate, the positive pressure of 4 pairs of brake discs of brake shoe reduces, braking force reduces, and braking oil pressure is high more, and braking force is more little, liner plate, brake shoe and cylindrical shell move right under the drive of return mechanism 1, brake shoe leaves brake disc, and produces certain brake clearance, and braking force is removed fully.
Claims (3)
1, a kind of mine hoist drg, by brake shoe, liner plate, cylindrical shell, oil cylinder, piston, piston bush, bearing pin, trimming screw, cup spring, composition such as seal ring, return mechanism, it is characterized in that: remove bearing pin, liner plate is the plane by brake shoe one side, and match by the form of the outer garden of cylindrical shell one side plate and cylindrical shell with seam: liner plate and cylindrical shell and plunger screw link together; Return mechanism and the thickening of liner plate thread connection place are also adopted blind hole.
2, want 1 described drg according to right, it is characterized in that: the other end of plunger is processed with certain tapering.
