Description

Miniature hoisting winch for high building

The miniature winch of a kind of high building relates to a kind of elevator, lifting, tractor equipment in the operation transportation.

Existing high building there is no miniature winch, the stairs climbing dolly that has only other attached wall Cargo Lift and invent recently, alleviated people to a certain extent and removed the labour intensity that thing is gone upstairs, but on the stairs climbing dolly ladder to tow same effort time-consuming, and during walking inadequately steadily, noise is big, bump is serious; Attached wall Cargo Lift then capital expenditure is big, heaviness, and maintenance expense height, fault is many, and many units back on probation suggestion is numerous and confused, and majority comes to an end to scrap.

The purpose of the utility model be to develop a kind of make simple, cost is low, efficient is high, safe and reliable, easy to use, be fit to the miniature winch of high building that constituent parts, each workshop and the vast resident of family carry light-duty goods.

The miniature winch of this high building is made up of driving device, hoisting mechanism, suspender, fixed mount four major parts.

Fig. 1 is the miniature winch structure lateral plan of high building;

Fig. 2 is the miniature winch structure front elevation of high building;

Fig. 3 is the gearbox designs figure of the miniature winch of high building;

Fig. 4 is reel, the clutch configuration figure of the miniature winch of high building.

Specify below in conjunction with accompanying drawing:

One, transmission device: comprise the worm gear (5), worm screw (4), speed increasing gear (6,7), wind (8), the shaft coupling (9) that have in base (1), motor (2), gearbox (3) and the gearbox;

Two, hoisting mechanism: comprise reel (10), drum shaft (11), rope winding jib (12), power-transfer clutch (13), power-transfer clutch (13) specifically comprises turncap (14), clutch key (15), screw rod (16);

Three, suspender: comprise that steel rope (17), pulley (18,19), suspension hook (20) can be for linking directly, also can be for having the hook of movable pulley.

Four, fixed mount: comprise lower roof plate (21), upper plate (22), push rod (23), height adjustment spanner (24), two-thread screw (25), cantilever (26), strut bar (27).

Concrete annexation: change speed gear box (3) is fixed on the base (1), change speed gear box (3) is made up of worm gear (5), worm screw (4), (shown in Figure 3), worm screw (4) is the single head straight sided axial worm, modulus m=4 millimeter, characteristic coefficient=11, the lead angle λ of worm screw=5 ° 11 ' 40 "; the tooth number Z z=29 of worm gear (5), overall ratio i=29.Thereby change speed gear box has self-locking property, worm screw (4) one ends connect electrical motor (2), the other end connects multiplying wheel (6,7) and wind (8), worm gear (5) connects plunging joint (9), plunging joint (9) is set on the drum shaft (11), drum shaft (11) is controlled by power-transfer clutch (13) with the clutch of reel (10), the structure of power-transfer clutch (13) as shown in Figure 4, turncap (14) is a fixing integral body with screw rod (16), middle part suit clutch key (15), have notch on the end at reel (10) center, tighten turncap (14), clutch key (15) drive is pressed in the end notch of reel (10), drum shaft (11) can drive reel (10) and rotate, otherwise, then can break away from separately, reel (10) twines multilayer steel rope (17), rope winding jib (12) is positioned at reel (10) top, it is a horizontal depression bar, two ends are fixed on the base (1), steel rope (17) also extends and by being installed in the fixed pulley (18 on the fixed mount, 19) be connected to suspension hook (20), the push rod of fixed mount (23) two ends are fixed with upper plate (22) respectively, lower roof plate (21), on, lower roof plate (21,22) be the plane and the integral body that is connected of groove, push rod (23) is interior overcoat form, push rod (23) middle part have one section for two-thread screw (25) and push rod (23) for being threaded, has height adjustment spanner (24) at the middle part of two-thread screw (25), rotation height adjustment spanner (24), push rod is elongated or shortened, two sections of cantilever (26) are affixed can regulate its extension elongation according to selecting for use of standby screw, on strut bar (27) cantilever mounted (26) and the push rod (23).

Embodiment: select rated frequency 50HZ for use, operating voltage 220V single-phase capacitance starting asynchronous motor, the change speed gear box worm screw is the single head straight sided axial worm, modulus m=4 millimeter, characteristic coefficient=11, lead angle λ=5 ° 11 ' 40 "; the worm gear number of teeth 29; overall ratio i=29, thereby change speed gear box has self-locking property, and reel adopts the multilayer steel wire to twine method; Rong Shengliang is 60 meters; mean speed of rope is 21m/min, and 75 kilograms of the biggest lifting capacities are if carry additionally a movable pulley; the biggest lifting capacity is 100 kilograms, this machine also can be manual, shakes handle with manpower, and thing is hung in same realization.

Advantage:

Compact conformation, easy to manufacture, cost is low, mounting or dismounting are convenient, maneuverability, lightly solid, function is unique, novel in design, efficient is high, safe and reliable, of many uses, strong adaptability, is a kind of good product that is worthy to be popularized.
