Detailed description of the invention

For the technical scheme making those skilled in the art be more fully understood that in this utility model, below in conjunction with this reality With the accompanying drawing in new embodiment, the technical scheme in this utility model embodiment is clearly and completely described, it is clear that Described embodiment is only a part of embodiment of the present utility model rather than whole embodiments.New based on this practicality Embodiment in type, the every other enforcement that those of ordinary skill in the art are obtained under not making creative work premise Example, all should belong to the scope of this utility model protection.

Refer to Fig. 2-4, the open a kind of brake of this utility model embodiment, this brake can be applied at crane On.Disclosed brake includes brake pump 100, linkage 200, clamping element 300 and manual unlocking device 500.

Identical described in brake pump 100, linkage 200 and clamping element 300 and background technology, brake pump 100 He Linkage 200 is installed on the base of brake, and clamping element 300 usually two, clamping element 300 is fixed on linkage On 200, form grasping part 400.Clamping element 300 reaches clamping by the action of linkage 200 or unclamps clamped thing Purpose.Linkage 200 has operating portion 210, and the expansion link 110 of brake pump 100 is positioned opposite with operating portion 210, brake pump The expansion link 110 of 100 stretch out can jack-up operating portion 210, and then linkage 200 action, reach clamping element 300 and unclamp and pressed from both sides The purpose of tight thing.

Brake disclosed in the present embodiment increases manual unlocking device on the basis of the brake described in background technology 500, manual unlocking device 500 includes track 510, rolls jack-up part the 520, first installation axle 530, rotating turret the 540, second installation Axle 550 and operation handle 560.

Track 510 is fixed on operating portion 210, generally can realize fixing by the way of welding.

First installs axle 530 is fixed on linkage 200, and rotating turret 540 is rotatably arranged in the first installation axle 530 On, around first, axle 530 can be installed and rotate.As a same reason, the first installation axle 530 can be by one end and linkage 200 The mode of welding realizes fixing.

Second installs axle 550 is fixed on rotating turret 540, rolls jack-up part 520 and is installed in rotation on the second installation axle On 550, rolling jack-up part 520 can rotate around the second installation axle 550.Roll jack-up part 520 to rotate with rotating turret 540, with The carrying out rotated, roll jack-up part 520 and produce interference with track 510, and then apply to make to operating portion 210 by track 510 Firmly, this active force is for driving operating portion 210 towards the direction jack-up that expansion link 110 stretches out.

Operation handle 560 is arranged on rotating turret 540, for driving rotating turret 540 to rotate for operator.

Brake disclosed in this utility model embodiment brake pump 100 break down and expansion link 110 cannot jack-up even During the operating portion 210 of linkage 200, operator's hand-held operation handle 560 drives rotating turret 540 to install axle 530 around first Rotating, the rotational of rotating turret 540 drives and rolls jack-up part 520 unitary rotation, along with the carrying out rotated, rolls jack-up part 520 Contact track 510 and then generation are interfered, and along with the carrying out rotated, roll jack-up part 520 and roll gradually jack-up along roller-way 510 Track 510, and then realize the purpose of indirect jack-up operating portion 210.Aforesaid operations finally can make clamping element 300 pine of brake Open.Visible, this utility model embodiment provides the brake of a kind of energy manual unlocking, therefore can solve current brake The expansion link 110 of brake pump cannot stretch out and cause linkage cannot drive the problem that clamping element unclamps holdfast.

It addition, brake disclosed in the present embodiment directly increases manually on the basis of the brake described in background technology Device for opening 500, it is not necessary to set up other auxiliary equipment, will not increase the structure complexity of brake.Use and roll jack-up Part 520 can ensure that jack-up operates stable, reliably carry out, other parts of brake will not be caused damage.Manual unlocking fills Putting 500 can be simple to operate with one man operation.

Refer to Fig. 4, operation handle 560 can be arranged on one end of rotating turret 540, and second installs axle 550 can be arranged The other end at rotating turret 540.The mode of this two ends distribution is easy to drive rotating turret 540 to rotate by operation handle 560.

Work during, the rotation of rotating turret 540 drive rolling jack-up part 520 rotate, and rotating turret 540 turn Move and need operation handle 560 to drive rotating turret 540 to realize.It is arranged in rotation with rolling jack-up part 520 at operation handle 560 On the basis of frame 540 two ends, it is preferred that the position that is connected with rotating turret 540 of operation handle 560 away from the first installation axle 530 away from From installing axle 530 less than first away from the second distance installing axle 550.This kind of distribution mode makes, and operation handle 560 drives and rotates Frame 540 rotational realizes rolling jack-up part 520 and more greatly rotates, and then contact track 510 more quickly, finally can improve The efficiency of manual unlocking brake and effect.

In order to implement operation more easily, the operation handle 560 in the present embodiment is action bars, and action bars can be to stretch Contracting part.Extensible member can change length, and then can preferably adapt to rotating operation space.The premise allowed in rotating operation space Under, action bars can extend the longest, can be more laborsaving.

In the present embodiment, track 510 is groove structure, and groove structure and rolling jack-up part 520 are along rolling jack-up part The axis direction location fit of 520.This location fit can ensure that rolling jack-up part 520 is more stably to by track 510 Implement active force to the operating portion 210 of linkage 200, be finally reached the purpose opening brake.

Roll jack-up part 520 and preferably employ rigid member, to improve jack-up effect.Concrete, rolling jack-up part 520 can be Roller, bearing etc..

Based on brake disclosed in this utility model embodiment, this utility model embodiment is also disclosed a kind of crane, institute Disclosed crane includes the brake in foregoing embodiments described in any one.

Herein, what each preferred version only emphasis described is different from other scheme, if each preferred version Do not conflict, can combination in any, the embodiment formed after combination is also within category disclosed in this specification, it is contemplated that Text is succinct, and the embodiment with regard to no longer being formed combination individually describes herein.

The above is only detailed description of the invention of the present utility model, makes to skilled artisans appreciate that or realize this Utility model.Multiple amendment to these embodiments will be apparent to one skilled in the art, herein institute The General Principle of definition can realize in the case of without departing from spirit or scope of the present utility model in other embodiments. Therefore, this utility model is not intended to be limited to the embodiments shown herein, and is to fit to former with disclosed herein The widest scope that reason is consistent with features of novelty.
