Detailed description of the invention
Embodiment is illustrated below in conjunction with Fig. 1 and Fig. 2:
As depicted in figs. 1 and 2, the dynamic brake device of crane, including 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 pivot about 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 respectively arranged at the two ends place of base plate 1, it is 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 naturalness 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 includes U-bracket 111 and reset screw mandrel 112, and described U-bracket 111 is arranged on the second support 7 and combines place between 8 in operation block 5 and the second brake block; Described reset screw mandrel 112 is arranged on the first support 10 and combines place between 12 at push rod screw 9 and first brake sheet, 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 part of U-bracket 111, the middle being positioned at the first support 10 and U-bracket 112 on reset screw mandrel 112 is provided with back-moving spring 113, reset screw mandrel 112 is compressible back-moving 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-bracket 111.
Optimal way is, the first described support 10 and the second support 7 are provided with scalable first brake sheet combination 12 and second brake block combination 8 in its natural state with the set screw 101 of brake disc 13 spacing.
The operating state drawn is done by doing when the operating state pushed away changes work into when this utility model works brake gear. The braking effort of static brake gear is from spring, and the power of dynamic brake device is from oil pump push rod. Static brake gear naturalness brake block combination is to hold brake disc tightly; During dynamic brake device naturalness, the combination of first brake sheet and the second brake block combine and brake disc separated state under the effect of back-moving spring, only operationally, the combination of first brake sheet and the combination of the second brake block just can hold brake disc tightly, play braking action.
Adopting the crane of dynamic brake device when routine work, crane is when close to destination locations, and travelling control returns to zero-bit, movable motor dead electricity, and crane leans on inertia walking. If at this moment using static brake gear, travelling control returns to zero-bit, and crane will stop, and causes product to rock. If brake failure or do not have brake gear, the stopping of crane will lean on the reversion of motor to brake, and this will result in the infringement of motor, gear-box etc. If using dynamic brake device, it is possible to take a little to stop, allowing crane buffer stop, the article that crane lifts would not rock due to inertia. The infringement so brought to crane is just only small. To handling safety offer convenience just very big.
Dynamic brake device belongs to a part for crane travelling gear, and during normality, the combination of first brake sheet and the combination of the second brake block and brake disc are separated states. during work, crane walking needs are parked in appointment position, employee is with foot crawl foot switch in operation, at this moment Oil pump electrical machinery obtains electric work, impeller in oil pump stirs the fluid in oil pump and produces thrust, oil pump push rod rises, the block that pushes the work forward rotates centered by bearing pin, rotation due to 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 from little to a certain extent, brake disc is embraced in the combination of first brake sheet and the combination of the second brake block, play skidding effect, this brake gear can play the effect a little stopped, crane is allowed slowly to stop, so it is lifted on the article on crane would not rock, reduce dangerous generation, benefit is brought to safety.
If stopping brake, as long as operation 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 brake gear is under the effect of back-moving 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 needing brake again, employee steps on foot switch again.
