Row, needs to design reasonable brake gear, is difficult to adjust braking strength in the prior art, and the too tight tower crane that brakes is difficult to rotate, and stops
Che Taisong tower crane easily drifts about.Common brake gear includes: 1, mechanical damping structure structure, withstands bearing by screw and realizes system
Dynamic, brake stability is poor, and service life is shorter；2, air bag bearing arrangement, when brake work when, need lasting inflation,
And need to keep pressure in whole process, energy consumption is larger, and when air bag breaks down or powers off, the failure of brake function moment；
3, cylinder brake structure, drawback are substantially similar with air bag bearing arrangement；4, electromagnetic brake, the complex cost of structure compared with
It is high.
Utility model content
In view of the above-mentioned state of the art, the technical problem to be solved by the utility model is to provide a kind of structure letters
Single, excellent in stability medical tower crane brake gear.
Utility model solves technical solution used by above-mentioned technical problem are as follows: a kind of novel medical tower crane brake dress
It sets, including top plate, air bag component, bottom plate and screw rod, the air bag component is set between top plate and bottom plate, and the screw rod runs through institute
Top plate and bottom plate are stated, the top plate is equipped with multiple stomatas be connected with air bag component, and the side of the top board undersurface is equipped with ditch
Slot, the other side are equipped with runner assembly, gas held chamber are formed between the groove and air bag component, the screw rod upper end passes through spiral shell
Mother is limited in top plate, and the screw rod bottom is equipped with brake shoes.
Further, the bottom plate is located at screw position equipped with counterbore, and the counterbore is interior to be equipped with dynamic clamping head and quiet clamping head and gland,
The dynamic clamping head and quiet clamping head upper end offsets with gland, and lower end offsets with brake shoes.Gland is set on elastic reset block, effectively prevent oil
Dirt, dust etc. enter, and improve equipment dependability.
Further, stop nut is connected between the screw rod and top plate.
Further, the dynamic clamping head and quiet clamping head is nylon block.
Further, the dynamic clamping head and quiet clamping head is multiple butterfly elastic slices for being overlapped mutually placement
Compared with prior art, the utility model has the beneficial effects that brake shoes is always under the non-working condition of brake gear
In impaction state, tower crane is in normally closed braking state；Under brake gear working condition, air bag inflation, screw rod stress is stretched, former
Locking mechanism separation, tower crane can be freely rotated.The brake process of brake gear without being powered, ventilation, one reduces energy consumption, two
Come the failure for preventing power-off from tower crane being caused to brake, safety and reliability are improved.The setting of dynamic clamping head and quiet clamping head is fast convenient for brake shoes
Speed accurately resets；And gland is set on elastic reset block, it effectively prevent greasy dirt, dust etc. to enter, it is reliable to improve equipment
Property.The utility model is designed reasonably is suitble to large-scale promotion.
Detailed description of the invention
Fig. 1 is the overall structure of the explosion figure of the medical tower crane brake gear of the utility model；
Fig. 2 is the medical tower crane brake gear overall structure cross-sectional view of the utility model.
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, for the preferred embodiment in the utility model embodiment,
Instead of all the embodiments.Based on the embodiments of the present invention, those of ordinary skill in the art are not making creation
Property labour under the premise of every other embodiment obtained, fall within the protection scope of the utility model.
As shown in Figs. 1-2, a kind of novel medical tower crane brake gear, including top plate 5, air bag component 6, bottom plate 7 and spiral shell
Bar 3, the air bag component 6 are set between top plate 5 and bottom plate 7, and the screw rod 3 runs through the top plate 5 and bottom plate 7, the top plate 5
Multiple stomatas be connected with air bag component 6 are equipped with, the side of 5 bottom surface of top plate is equipped with groove 501, and the other side is equipped with rotation
Component forms gas held chamber between the groove 501 and air bag component 6, the screw rod 3 runs through the top plate 5 and bottom plate 7,
3 upper end of screw rod is limited in top plate 5 by nut 1, and 3 bottom of screw rod is equipped with brake shoes 4.
The runner assembly can be it is hinged, shaft is set in one of them of bottom plate 7 or top plate 5, at another
