Abstract
The utility model discloses a domestic hand hoist, which comprises bases, a support or hanger frame, a speed reducing device and a cranking bar. The base comprises an upper base, a lower base and a middle shaft. The middle shaft is connected with the upper and the lower bases through two threads whose both ends are rotated in an opposite direction. The rotation middle shaft can be retracted into the bases in order to conveniently be fixed on a floor slab. The speed reducing device comprises a big coaxial roller and a small coaxial roller. The diameter of the two rollers is unequal. The both ends of the hoisting ropes can be winded on the two rollers through pulley groups in an opposite rotation direction, which can make the hoist save force by the function of differential speed reducing. The utility model has the advantages of simple structure and convenient moving, which is particularly suitable for usage of family buildings.
Description
The utility model relates to a kind of hand crane, and particularly a kind of family expenses hand crane is used for hoisting heavy on the building.
Known hand crane is made up of support, suspension and support, speed reduction gearing and crank, its support need with lower margin fix or with a very heavy base to keep the stable of hoisting crane, its speed reduction gearing employing gear or Worm gear mechanism.Thereby complex structure, fixing difficulty, cost is higher, and this is its shortcoming, is unsuitable for adopting in the family house.
Task of the present utility model provides a kind of like this hand crane, and is simple in structure, cost is lower, available simple method is fixed on the building thereby be suitable for family adopts.
Task of the present utility model realizes with following mode: adopt the vertical pipe type support, this support has a upper bed-plate, a lower bottom base and an axis; Axis is connected with upper and lower base respectively by two sections opposite screw threads of its two ends rotation direction, thus when rotating middle shaft Up/down base just can stretch as required can hold out against in about between the floor.The triangle suspension and support of a usable rotational direction is installed on the standpipe support, is used for supporting, hoisting heavy.Speed reduction gearing adopts two different coaxial cylinders of diameter to form, and the hoisting cable two ends are around on two cylinders on the contrary by the assembly pulley rotation direction.Coaxial because of two cylinders, its rotation is synchronous, and the retractable speed difference of hawser played the effect of differential reducing when its diameter difference made the cylinder rotation.
Like this by a standpipe support, a suspension and support and two hand cranes that coaxial cylinder is formed.Just seem simple in structure, cost is lower, mobile, convenient fixing, be specially adapted to use on family's building.
The utility model will be further described below in conjunction with accompanying drawing:
Fig. 1 is the utility model elevation drawing.
Fig. 2 is the utility model A-A section-drawing.
As shown in the figure: (1) is upper bed-plate; (2) be axis; (3) be lower bottom base; (4) be top bottom-disc; (5) be low bottom-disc; (6) be handle; (7) be suspension and support; (8) be swift; (9) be doffer; (10), (12), (13) are assembly pulley; (11) be hawser; (14) be the brake card; (15) be crank.
Referring to Fig. 1: upper bed-plate (1), axis (2), lower bottom base (3) are formed vertical pipe type support of the present utility model, and axis (2) is connected with lower bottom base (3) with upper bed-plate (1) respectively by the opposite screw thread of two ends rotation direction; Have handle (6) on the axis (2) thus being used for rotating middle shaft makes base flexible.For base can be fixed on the floor better, chassis (4), (5) that floor space is bigger can be arranged on the Up/down base; Suspension and support (7) is loaded on the vertical pipe type support, and the flexible standpipe rotates, rotational orientation when conveniently hanging thing.Suspension and support (7) adopts the hinge joint spider in the present embodiment.
Referring to Fig. 2: assembly pulley (12), (13) size two coaxial cylinders (8), (9) different with diameter are installed on the suspension and support (7).The hawser two ends are around on cylinder (8) and (9) on the contrary by assembly pulley (12), (13) rotation direction respectively, because of cylinder (8), (9) coaxial, their synchronous rotations when shaking crank (15), cause two diameter of cylinder are not of uniform size, cause folding and unfolding hawser speed difference, produce the differential reducing effect, be able to laborsaving when making lifting.
In order to prevent accident, brake card (14) can be installed on the cylinder, brake card (14) can be ratchet anti-reverse mechanism or other anti-reverse mechanisms.
The utility model adopts in high-rise building because of simple in structure, conveniently moving, particularly suitable.
Claims (1)
1, a kind of hand crane, by support, suspension and support, speed reduction gearing and crank are formed, it is characterized in that: the vertical pipe type support that support is made up of upper bed-plate (1), lower bottom base (3) and axis (2), axis (2) is connected with lower bottom base (3) with upper bed-plate (1) respectively by two sections opposite screw threads of two ends rotation direction; Two coaxial cylinders of size (8) that speed reduction gearing is not waited by diameter, (9) and assembly pulley (12), (13) are formed, and hawser is around on two cylinders (8), (9) on the contrary by assembly pulley (12), (13) and two ends rotation direction.
