Embodiment
Embodiment is illustrated below in conjunction with Fig. 1 and Fig. 2:
As depicted in figs. 1 and 2, the dynamic brake device of hoist, comprise base plate 1 and oil pump 2, described oil pump 2 is connected with Oil pump electrical machinery 3 and oil pump push rod 4, the end of described oil pump push rod 4 is connected with one end of operation block 5, and operation block 5 is articulated and connected on the second support 7 by bearing pin 6, and operation block 5 can rotate centered by bearing pin 6 under the effect of oil pump push rod 4, the other end of the second support 7 is arranged on base plate 1, the second support 7 is arranged and is connected with the second brake block combination 8; The other end place of described operation block 5 is connected with push rod screw 9, described push rod screw 9 is connected on the first support 10, the other end of the first support 10 is arranged on base plate 1, first support 10 and the second support 7 are arranged at the two ends place of base plate 1 respectively, be connected by resetting means 11 between first support 10 and the second support 7, first support 10 and the second support 7 can return to nature under the effect of resetting means 11, the first support 10 is arranged and is connected with first brake sheet combination 12; Described first brake sheet combination 12 and the middle of the second brake block combination 8 are provided with brake disc 13; The first described support 10 and the second support 7 can be close to each other under the drive of operation block 5, and now first brake sheet combination 12 and the second brake block combination 8 can complete dynamic brake to brake disc 13 is close simultaneously.
Optimal way is, described resetting means 11 comprises U-shaped support 111 and reset screw mandrel 112, and described U-shaped support 111 is arranged on the second support 7 and locates between operation block 5 and the second brake block combination 8; Described reset screw mandrel 112 is arranged on the first support 10 and locates between push rod screw 9 and first brake sheet combination 12, one end of reset screw mandrel 112 is arranged on the first support 10, the other end of reset screw mandrel 112 is arranged at the opening of U-shaped support 111, middle reset screw mandrel 112 being positioned at the first support 10 and U-shaped support 112 is provided with Returnning spring 113, reset screw mandrel 112 is compressible Returnning spring 113 when the first support 10 and the second support 7 close to each other, and one end of reset screw mandrel 112 can constantly extend in U-shaped support 111.
Optimal way is, the first described support 10 and the second support 7 are provided with adjustable first brake sheet combination 12 and the second brake block combination 8 in its natural state with the adjusting screw 101 of brake disc 13 spacing.
Do by doing when the operating state pushed away changes work into the operating state drawn when the present invention works braking device.The braking effort of static braking device is from spring, and the power of dynamic brake device is from oil pump push rod.Brake disc is held in the combination of static braking device nature brake block tightly; During dynamic brake device nature, the combination of first brake sheet and the second brake block combine and brake disc separated state under the effect of Returnning spring, only have operationally, the combination of first brake sheet and the combination of the second brake block just can hold brake disc tightly, play braking action.
Adopt the hoist of dynamic brake device when routine work, hoist is when close to destination locations, and travelling control gets back to zero-bit, movable motor dead electricity, and hoist is by inertia walking.If at this moment use static braking device, travelling control gets back to zero-bit, and hoist will stop, and causes product to rock.If brake failure or do not have braking device, the stopping of hoist will lean on the reversion of motor to brake, and this will cause the infringement of motor, gear-box etc.If use dynamic brake device, just can take a little to stop, allow hoist buffer stop, the article that hoist lifts would not rock due to inertia.The infringement brought to hoist is like this just very little.To handling safety offer convenience just very large.
Dynamic brake device belongs to a part for crane travelling gear, and during normality, the combination of first brake sheet and the second brake block combine and brake disc is separated state.During work, hoist walking needs to be parked in specified position, operative employee is with pin crawl foot switch, at this moment Oil pump electrical machinery obtains electric work, the fluid that impeller in oil pump stirs in oil pump produces thrust, oil pump push rod rises, the block that pushes the work forward rotates centered by bearing pin, due to the rotation of operation block, pull push rod screw, at this moment the distance between the first support and the second support reduces, the distance between the combination of first brake sheet and the combination of the second brake block is driven also to reduce, when apart to a certain extent little, brake disc is embraced in the combination of first brake sheet and the combination of the second brake block, play skidding effect, this braking device can play the effect of a little stopping, hoist is allowed slowly to stop, the article be lifted on like this on hoist would not rock, reduce dangerous generation, benefit is brought to safety.
If stop brake, as long as operative employee decontrols foot switch, Oil pump electrical machinery dead electricity, impeller in oil pump stops operating, oil pump push rod just loses power, and this braking device is under the effect of Returnning spring, and the first support and the second support are separately, drive the combination of first brake sheet and the combination of the second brake block separately, brake failure.
If need brake again, employee steps on foot switch again.
