Upper and lower side is respectively equipped with metal (upper, and the lower section of lower bearing is equipped with for accepting the stacker of lower bearing on pedestal cylinder,
The top of upper bearing (metal) is equipped with for compressing the nut seat of upper bearing (metal) on pedestal cylinder, and base plate also passes through guide post and is connected with place
Mounting base above nut seat, mounting base is interior to be equipped with ring-shaped brake block, is equipped between mounting base and brake shoes for driving brake
The spring that vehicle block and nut seat frictional connection brake is additionally provided on base plate and transports upwards for drive installation seat along guide post
It is dynamic to separate the cylinder mechanism for carrying out un-brake with nut seat with driving brake block.
Preferably, mounting base includes mounting seat body and the adjusting ring above mounting seat body, mounting seat body
Equipped with interior edge, ring-shaped brake block is equipped with the outer matched with interior edge, and spring is between adjusting ring and outer.
It is highly preferred that interior along locating slot is equipped with, outer is equipped with the locating piece cooperated with locating slot.
Compared with prior art, a kind of gas on tower crane is provided the beneficial effects of the present invention are: the present invention to stop knot
Structure drives annular brake shoes and pedestal cylinder top nut seat to carry out brake locking, cylinder machine is used when needing un-brake using spring
Structure pushes brake shoes to separate with nut seat, and the gas brake structure operation is simple, and failure rate is low, long service life.
Detailed description of the invention
Fig. 1 is a kind of perspective view of the gas brake structure on tower crane provided by the invention；
Fig. 2 is to invent cross-sectional view in a kind of gas brake structure on tower crane provided；
Fig. 3 is the schematic diagram for inventing mounting base in a kind of gas brake structure on tower crane provided；
Fig. 4 is the schematic diagram for inventing annular brake shoes in a kind of gas brake structure on tower crane provided.
Specific embodiment
Preferred embodiment provided by the invention is illustrated with reference to the accompanying drawings.
Fig. 1 to Fig. 4 is a kind of preferred embodiment of the gas brake structure on tower crane provided by the invention.Extremely such as Fig. 1
Shown in Fig. 4, which includes pedestal cylinder 10, and rotation is socketed with base plate 20, pedestal on pedestal cylinder 10
The upper and lower side of plate 20 is respectively equipped with metal (upper 21,22, and the lower section of lower bearing 22 is equipped on pedestal cylinder 10 for accepting
The stacker 11 of lower bearing 22, the top of upper bearing (metal) 21 are equipped on pedestal cylinder 10 for compressing the nut seat of upper bearing (metal) 21
12, base plate 20 is also connected with the mounting base 40 above nut seat 12 by guide post 30, is equipped with annular in mounting base 40
Brake shoes 50 is equipped between mounting base 40 and brake shoes 50 and brakes for driving brake block 50 with 12 frictional connection of nut seat
Spring 41, be additionally provided on base plate 20 and move upwards for drive installation seat 40 along guide post 30 with driving brake block 50 and spiral shell
The separation of base 12 carries out the cylinder mechanism 60 of un-brake, in this way when pedestal cylinder 10 to be guaranteed does not rotate, 41 drive ring of spring
Shape brake shoes 50 brakes with 12 frictional connection of nut seat, and when needing un-brake, cylinder mechanism 60 overcomes mounting base 40
The pressure that gravity and spring 41 apply, pushes mounting base 40 to rise, so that ring-shaped brake block 50 is separated with nut seat 12, brake
Un-brake between block 50 and nut seat 12.
