The specific embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is done further description.
Fig. 1 is a pneulift structural representation of the present invention; Fig. 2 is the winch structure scheme drawing of pneulift of the present invention.
See also Fig. 1 and Fig. 2, pneulift provided by the invention comprises winch 2, hand basket 1 and steel rope 3, and winch 2 is installed on the bottom of hand basket 1; Wherein, winch 2 is provided with pneumatic paddle formula motor 6, and pneumatic paddle formula motor 6 links to each other with reel 4 through reductor 5, and reel 4 links to each other with hand basket 1 through steel rope 3.The hand basket 1 preferred aluminum alloy frame that adopts can be provided with lift controil valve 7 on it, and the part of winch 2 is that aluminum alloy is processed.Pneumatic paddle formula motor 6 is connected with reductor 5, then with reductor 5 be fixed on the suspension bracket after reel 4 is connected.Pneulift in use need not the rail frame, only needs the steel rope 3 on top is fixed on the top of operating range, and the staff in the hand basket 1 just can control the operation that the lift controil valve 7 in the hand basket 1 rises and descends.Pneulift hovers over when aerial, and except that manual steel rope 3, worm and gear (figure does not show) is provided with auto-lock function; When the lead angle of worm screw during less than the equivalent friction angle of meshing wheel between cog, mechanism has self-locking performance, can realize reverse self-locking; Promptly can only drive turbine by worm screw; And can not drive worm screw by turbine, and when guaranteeing that elevator hovers, the safety of personnel, material and equipment.
Fig. 3 is the scalable overload protection device structural representation of pneulift of the present invention.
Please continue referring to Fig. 3, winch 2 is provided with the scalable overload protection device, comprises Pneumatic valve 9, set screw 8, strut bar and support (figure does not show).The scalable overload protection device utilizes lever principle, utilizes the antagonistic force of reductor 5 when driving reel 4, and reductor rotates up angle θ; When angle θ exceeds in the scope of prior setting; Set screw 8 is sealed Pneumatic valve 9, and this moment, the loop of motor was sealed, and motor stops operating; When removing overload, immediately can the normalisation running.
Fig. 4 is the reel speed-limit device structural representation of pneulift of the present invention.
Please continue referring to Fig. 4, reel 4 is provided with speed-limit device, and said speed-limit device is made up of Pneumatic valve 9, set screw 8 and strut bar, and Pneumatic valve 9 one ends are connected with pneumatic paddle formula motor 6, and the other end is connected with lift controil valve 7.When the normal decline work of winch 2, reel 4 drives brake disc 44 and rotates when rotating; 44 pendulum plate 42 can be through first boss 41 on the fixing steel band on the brake disc, and pendulum plate 42 utilizes torsion spring to reset and skips second boss 43 simultaneously, and reel 4 is with regard to the work of ability normal rotation like this; Like accident; Winch 2 descending speeds are too fast to be that reel 4 rotating speeds are too fast, on the brake disc 44 pendulum plate 42 through first boss 41 on the fixing steel band after, owing to brake disc 44 rotative speeds are too fast; Torsion spring and pendulum plate 42 are not accomplished to reset and are annotated by second boss, 43 cards, and this moment, reel 4 just stopped operating.
In sum, pneulift provided by the invention has following advantage: 1) pneulift provided by the invention is propulsion source with the pressurized air, discharge pollution-free, and can centralizedly supply, the remote conveying; 2) pneulift provided by the invention is provided with the scalable overload protection device, is used for protecting the personal security of pneulift and hand basket; 3) winch provided by the invention has auto-lock function, when guaranteeing that pneulift hovers, and the safety of personnel, material and equipment; 4) material of pneulift provided by the invention is an aluminum alloy, light weight, convenient transportation.
Though the present invention discloses as above with preferred embodiment; Right its is not that any those skilled in the art are not breaking away from the spirit and scope of the present invention in order to qualification the present invention; When can doing a little modification and perfect, so protection scope of the present invention is when being as the criterion with what claims defined.
