The working principle of the braking device provided by the embodiment of the invention is as follows:
when in use, the first pressure plate 21a and the second pressure plate 21b are arranged at two sides of the brake pad 0 of the equipment needing braking. When braking is needed, pressure oil is introduced into the flow passage 112, and since the piston rods on the first actuating mechanism 2a and the second actuating mechanism 2b are communicated with the flow passage 112, if one of the piston rods starts to move under the pressure of the pressure oil, the rest of the piston rods inevitably start to move, so that the piston rods can keep good synchronism. When the first actuating mechanism 2a and the second actuating mechanism 2b are both acted by pressure oil, the first pressure plate 21a and the second pressure plate 21b are close to each other, so that the brake pad 0 positioned between the first pressure plate 21a and the second pressure plate 21b is clamped;
in the process of braking, along with the movement of the first pressing plate 21a, the first elastic member 115 is driven to move in the first channel 113, the bottoms of the first nut 1153 and the first channel 113 apply pressure to two ends of the first spring 1151, so that the first spring 1151 is compressed, elastic potential energy is accumulated, after braking is finished, pressure oil is released, the piston rod is no longer subjected to pressure, then the first piston rod 22a, the second piston rod 22b, the fifth piston rod 22c, the first pressing plate 21a and the first bolt 1152 return to the original position rapidly under the action of the elastic force of the first spring 1151, so that the first pressing plate 21a is separated from the brake pad 0 rapidly, at this time, the arrangement of the first positioning member 116 and the first positioning hole can prevent the pressing plate from deviating under the action of the elastic force, and the first pressing plate 21a can keep translational movement. Similarly, the second pressing plate 21b can be quickly separated from the brake pad 0 by the second elastic member 125.
The braking device provided by the embodiment of the invention has the beneficial effects that:
1. when the braking device provided by the invention is used, the first pressure plate 21a and the second pressure plate 21b are positioned at two sides of the brake pad 0. During braking, the first pressing plate 21a and the second pressing plate 21b are driven by the piston rods to approach each other, so that the brake pad 0 is clamped, and a braking effect is achieved. Because first actuating mechanism 2a and second actuating mechanism 2b are last all to have set up two at least piston rods, can increase the braking force to be applicable to large-scale machinery and use, and because each piston rod all communicates with runner 112, guaranteed that first clamp plate 21a and second clamp plate 21b can the simultaneous movement, thereby make the synchronism of multiunit piston rod better, provide more reliable and more stable braking force.
2. First connecting block 11 and the fixed linking to each other of second connecting block 12 detachably can reduce this arresting gear's the processing degree of difficulty, also is convenient for overhaul and maintain this arresting gear.
3. Through setting up first elastic component 115 and second elastic component 125, after the braking, can drive first clamp plate 21a and second clamp plate 21b quick return through the elastic potential energy that the elastic component accumulated.
4. The first piston rod 22a, the second piston rod 22b and the fifth piston rod 22c are distributed along an arc line, and the layout is more reasonable and compact.
5. By arranging the first positioning member 116 and the second positioning member 126, the first pressing plate 21a and the second pressing plate 21b can be prevented from being deflected due to uneven force during the movement process.
6. The first pressing plate 21a and the second pressing plate 21b both form a ladder structure, the non-overlapping part of the first plate surface 211a and the second plate surface 212a can be used for arranging the first elastic part 115 and the first positioning part 116, and the non-overlapping part of the third plate surface 211b and the fourth plate surface 212b can be used for arranging the second elastic part 125 and the second positioning part 126, so that the elastic part and the positioning part are prevented from contacting with the brake pad 0, and the layout of the device is more reasonable.
