Description

A kind of hanging basket hoisting

The utility model relates to a kind of aerial work basket gig.

Aerial work basket has obtained increasingly extensive application as a kind of exterior wall finishing machinery in the construction of multilayer or skyscraper.Hanging basket hoisting plays crucial effect as the engine installation of hanging basket to workmen's safety and comfort.At present, generally the hanging basket hoisting of Shi Yonging can be divided into two kinds on S type and a type according to the rope climbing form.S type hanging basket hoisting generally adopts worm gear pairs to slow down, and the plane extruded cords rope at mouth dependence platen and rope sheave produces friction, and steel rope is the S shape along two groups of rope sheaves and moves, and drives the hanging basket lifting.The major defect of S type hanging basket hoisting is that the steel rope cross section produces bigger elastic deformation under the strong extruding of rope sheave, and noise is big, easily heating, steel rope are easy to wear, and service life is short.A type hanging basket hoisting generally adopts gear reduction system, and the mouth steel rope is a shape along race and moves, though the elastic deformation of steel rope is less, the gear of deceleration system all adopts oil lubrication, and structure is complicated, and thermal diffusivity is relatively poor.And above-mentioned existing hanging basket hoisting all adopts more than three grades, and tradition, complete machine structure are complicated, maintaining is had relatively high expectations.

The purpose of this utility model provide a kind of simple in structure, steel rope abrasion is little, working stability is reliable, long service life, maintaining hanging basket hoisting simply and easily.

The external tooth of the transmission shaft that the utility model comprises motor 1 on casing 16, the casing 16, rope distributor 14, press centrifugal speed limiter 15 in rope mechanism and the casing 16, its principal character is motor 1 affixed gear wheel shaft 17, gear wheel shaft 17 1 ends in centrifugal speed limiter 15 is connected the worm gear centre hole of worm screw, worm gear pairs 9 of worm gear pairs 9 is meshed with the teeth of trough of belt inner gear 19.Said pressure rope mechanism is become for 6 grades by the pinch roller on depression bar 2, pull bar 8, spring 12, pressing

plate

5,7 and the pressing plate, one end of depression bar 2 is connected with casing 16 through bearing pin 3, the other end is through bearing pin 3 ' be connected with pull bar 8, pull bar 8 passes adapter plate 13 and is set with spring 12, and pressing

plate

5,7 is connected with depression bar 2 through bearing pin 4.

Be provided with in the casing 16 of the present utility model oil pocket 16 ', the axle body of worm gear pairs 9 and gear wheel shaft 17 place oil pocket 16 ' in.Oil pocket 16 ' outer wall dissipating cover 11 is arranged.

The utility model has the advantages that: 1, adopt worm gear pairs, gear wheel shaft and the transmission of trough of belt inner gear secondary to simplify complete machine structure, alleviated fuselage weight, and consumption of power and cal val are obviously reduced.2, press rope mechanism and rope distributor to make hanging basket in lifting process according to the motion automatic compensation impaction state of steel cable at race, the distortion and the wearing and tearing of steel cable reduce to minimum degree.3, deceleration system adopts the worm gear pairs oil bath lubrication, not only can reduce mechanical wear, and improve radiating condition.

Accompanying drawing 1 is the utility model structural representation.

Accompanying drawing 2 is the utility model A-A cutaway view.

Among the figure: 1-motor, 2-depression bar, 3,3 ', 4-bearing pin, 5,7-pressing plate, 6-pinch roller, 8-pull bar, 9-worm gear pairs, 10-steel cable, 11-dissipating cover, 12-spring, 13-adapter plate, 14-rope distributor, 15-centrifugal speed limiter, 16-casing, 17-gear wheel shaft, 18a, 18a ', 18b,

18b '

18c, 18c '-bearing, 19-trough of belt inner gear.

Motor 1 of the present utility model is fixed on the flange of casing 16, and the transmission shaft of motor 1 is by the worm screw of centrifugal speed limiter 15 connection worm gear pairses 9, and affixed gear wheel shaft 17, gear wheel shaft 17 are loaded on the casing 16 by bearing 18a, 18a ' in the centre hole of worm gear.Rope distributor 14 is that prior art, its little garden arc insert in the race of trough of belt gear 19, and big garden arc then is fixed on the casing 16 along the trough of belt outside diameter of gear outward.Pass casing 16 behind the steel cable 10 strip winding groove inner geares 19.Trough of belt inner gear 19 is by bearing 18c, 18c ' supporting.Press rope mechanism then to be fixed on the relevant position of casing 16 along the groove camber line of trough of belt inner gear 19.During work, steel cable 10 enters in the race of trough of belt inner gear 19 by rope distributor 14, under the drive of trough of belt inner gear 19, steel cable 10 runs to pinch roller 6 places of rope mechanism, jack-up pinch roller 6, pinch roller 6 can be provided with 3, pinch roller 6 makes pull bar 8 holddown springs 12, and the antagonistic force of spring 12 is by pull bar 8, depression bar 2, pressing

plate

5,7 and bearing pin 4, just pinch roller 6 is close to steel cable 10, and according to steel cable 10 dynamics of compressing is adjusted in the motion in race voluntarily, make the distortion and the wearing and tearing of hanging basket steel cable 10 in lifting process be reduced to minimum degree, steel cable 10 passes casing 16 by rope distributor 14 from another rope hole along the race of trough of belt inner gear.Oil pocket 16 in the casing 16 ' in be full of machine oil, the dissipating cover 11 of oil pocket 16 ' outer, in order to increase heat delivery surface, to improve radiating condition.
