Abstract
The utility model relates to an automatic compensating brake which is an improvement of the existing outer embracing brake. The utility model comprises two brake arms with brake pads, a draw rod with an automatic compensator, and a lever which connects a motility structure, a spring arrangement, brake arms, and the automatic compensator. When the lever is driven upward by the motility unit, the draw rod is driven downward, which causes the two brake arms spread out, and then the machines can be operated according to requirements. When the power is off, the lever is driven downward by a spring push rod, and then the draw rod is driven upward, which causes the two brake arms to be closer, and then the clearance compensation between the brake pads is achieved through the compensator, and the two brake pads clip or hold the brake disc to carry out braking.
Description
The utility model relates to a kind of drg, is the safety device that is used on lifting, transportation, metallurgy, mine, the vehicle for construction.
Existing external-contacting brake is to hold brake wheel tightly by the brake shoe or the strap of the brake, plays brake action, and its shortcoming is: (1) braking is not steady, and impulsive force is big, poor reliability; (2) the wooden fork pad wear inequality of rubbing, degree of utilization is low; (3) in the operating process, need often to adjust; (4) poor radiation; (5) slide hook phenomenon is serious, and safety factor is low, causes the accident easily.
Task of the present utility model is the improvement to prior art, provides that a kind of braking is reliable, slipper can self-conpensating side clamp type drg, also can by manually reach drg often open or normally closed.
Structure of the present utility model comprises:
(1) base
(2) left and right sides brake control lever, the lower end is hinged on the base respectively, and withstands the location by the adjustment screw rod that is fixed on the base from the left and right sides,
(3) left and right sides slipper is hinged on the inboard corresponding position of left and right sides brake control lever
(4) actuating unit, lower end are contained on the base, and the power push-rod of upper end leans on electronic or hydraulic-driven,
(5) spring installation, spring bracket are hinged on the base, and the spring push-rod that is connected with spring is contained on the spring bracket
(6) lever is connecting hydraulic push rod, spring push-rod and right brake control lever upper end, and its left end has an elbow that upwarps
(7) pull bar, left end are hinged on the left brake control lever, and right-hand member is threaded with the star-wheel of automatic compensating device,
(8) automatic compensating device comprises
(8.1) directional clutch, ball-type or carve the piece formula, its star-wheel has extension pipe, and outer ring surface has bar-shaped trough,
(8.2) square joint axle is contained on the bend of lever,
(8.3) pulls pin, be fixed on the bend of lever, and inserting is in the bar-shaped trough of directional clutch outer shroud,
(8.4) be connected with the star-wheel and the extension pipe thereof of the directional clutch of tie-bar in, pass the square joint axle and link to each other with nut.
In addition, the utility model also is equipped with a hand gear, is hinged on the cross bar on the base of engine installation lower end and the perpendicular thick stick that is hinged between lever right-hand member, the whippletree left end constitutes by the middle part.In case of necessity, by manually can realize drg often open or normally closed.
Advantage of the present utility model is: (1) braking force and spring force are linear relationship, impact for a short time, and braking procedure is steady; (2) ferrodo need not to adjust in the whole working life phase, can keep constant wearing clearance, and lock torque is constant; (3) perfect heat-dissipating, the service life of having improved brake efficiency and Friction disk; Reduced slide hook distance, operating maintenance is convenient.(4) have outer armful, two kinds of functions of side folder.(5) by the pushing to or leaving behind of manual push rod, can realize drg often open or normally closed, can realize drg often open or normally closed.

Fig. 1 is the front view of the utility model embodiment,
Fig. 2 is the birds-eye view of Fig. 1,
Fig. 3 is an automatic compensating device cutaway view among the embodiment,
Fig. 4 is the A-A cutaway view of Fig. 3.
Below in conjunction with attached view the utility model embodiment is described in further detail.
As shown in Figure 1 and Figure 2, left and right sides brake control lever 6,7 is assembled by steel plate, the bottom is hinged on the troffer of base 1 with axle respectively, and by screw rod on the troffer that is fixed on base 12 and screw rod 3, withstands on the bolt of rear end plate of left and right sides brake control lever 6,7 lower ends and adjusts the location.Left and right sides slipper 4,5 is hinged on the inboard corresponding position, middle part of left and right sides brake control lever 6,7 with axle respectively, and adjusts front and back position by the bolt that is contained on the brake control lever.Spring installation 12 comprises that one is hinged on the spring bracket on the base 1 with axle and is contained on the support and drives the spring push-rod of spring up-down stretch and compression in support.Hydraulic efficiency gear 14 lower ends are hinged on the base 1 with axle, and the upper end is a hydraulic push rod that is driven by electric oil pump.The right-hand member of the lever 13 that is assembled into by two clamping plates, middle part, left side link to each other with the upper end of hydraulic push rod, spring push-rod, right brake control lever 7 by axle successively.At lever 13 left ends one elbow that upwarps is arranged, bend part is assembling automatic compensating device.
As shown in Figure 3, Figure 4, outer shroud 18 surfaces of the ball-type directional clutch of automatic compensating device have bar-shaped trough 20, be contained in finger 17 insertings on lever 13 elbows in bar-shaped trough 20, directional clutch in-to-in star-wheel 19 has extension pipe, and it passes the square joint axle 10 that is contained on pull bar 13 elbows and links to each other with nut.Pull bar 8 is contained in star-wheel 19 and the extension pipe thereof by screw thread.The middle part of the cross bar 16 of hand gear is hinged on the engine installation 14 lower end bases 1, and montant 15 upper ends are hinged on the right-hand member of lever 13, and the lower end is hinged on the left end of cross bar 16.
The working process of present embodiment is: after the energising, it is up that the hydraulic push rod of hydraulic efficiency gear 14 drives lever 13, spring push-rod drives length of spring compressed, the bend part of lever 13 is descending, finger 17 is stirred outer shroud 18 and is relaxation state, then pull bar 8 is pushed two brake control levers 6,7 open, makes slipper 4,5 be opening-wide state, and at this moment machinery can be operated with the need.After outage, spring push-rod is under the effect of spring force, it is descending to drive lever 13, the elbow of lever 13 is up, finger 17 is stirred outer shroud 18 and is locking state, star-wheel 19 screws along pull bar 8, and left and right sides brake control lever 6,7 is progressively close, clamps or embraces brake disc up to two slipper 4,5 and play brake action.
