Abstract

The utility model provides a novelcrane for family use which has a simple structure and occupies no utilization area of balconies. The utility model comprises a lifting arm, a movable pulley, a hook, a fixed pulley, a steel cable, a hoisting mechanism and a fastening device. The suspended arm of crane for family use is flexible in order to prevent bumping walls when lifting mass weight like bicycles. While the utility model is in use, the hoisting of weight can be immediately completed by operating the hoisting mechanism by human effort or driving the hoisting mechanism by the motor.

Description

Crane for family use

The present invention relates to a kind of manpower, power with using hoisting crane, is to solve upstairs resident family to carry bicycle, coal briquette and so on bont than the weight body up and down.

The light hoisting gear of selling on the market generally needs to be made up of heavier, bigger hoisting crane base, hoist frame, crane arm and hoisting mechanism now.Need take when the shortcoming of such hoisting crane is to use than large tracts of land, install to move inconvenient, according to building requirements, common balcony did not allow heavy duty yet.Moreover complex structure, the cost height, this cost is very uneconomical, economical for general family, so the difficulty of popularization.

The objective of the invention is not account for usable floor area, economic, practical, labour-saving weight bont for family provides.

Invention is to realize like this.Two fixed pulleys are loaded onto in top and inclined to one side rear end at arm, and with the L type card with certain mechanical strength, the arm that can stretch is fixed on the building eaves.But with will be with the cable drum of labour-saving rocking handle, power wheel with quadrat method, be fixed on railing or other fixture, then steel rope one end is fixed on the arm top, the other end arrives cable drum and fix tightly by being fixed on movable pulley on the cargo hook and arm top, two fixed pulleys in rear portion.Shake handle or power drags, can promote weight.Owing to used movable pulley, laborsaving rocking handle or power wheel, so can economize 80% power.

Below with reference to accompanying drawing invention is described in detail.

With reference to accompanying drawing, at arm (a 1) top and a rear portion with good mechanical strength, each uses pin (7,12) the last fixed pulley (2 of pin, 11) arm (1) penetrated band slip cap (8), have in the L type fixed card (9) of good mechanical strength, be stuck on the building eaves (10), the cable drum (13) that band is had the L type fixed card (16) of good mechanical strength is fixed on railing or other fixture, one end of steel rope is fixed on the top of arm (1), make steel rope (3) by sell the movable pulley (4) on cargo hook (6) with pin (5), then by two fixed pulleys (2 in arm (1) top and inclined to one side rear portion, 11), arriving cable drum (13) goes up and fix tightly.In concrete structure, fixed card (9,16) should make the bent angle of 45-90 degree, and load onto one and regulate Luo Ding (18,17), building eaves, railing or other fixture in order to the chucking different-thickness, and adorn a pad regulating the Luo Ding top, in order to increase area of contact, here why fixed card (9) will adorn a slip cap, be for arm (1) can be stretched, and also can increase the tensile strength of arm (1).

During operation, with carry and fall weight and be hung on the cargo hook (6), shake handle (15) or motor and drag the lifting that power wheel (14) can be finished weight.

Claims

1, promotes weight, particularly building resident family promotes the bont of the required weight of life, this device has one directly to be fixed on arm (1) on the building eaves (10) with L type fixed card (9), one end of hoist rope (3) is fixed on the top of arm (1), the other end arrives the cable drum (13) that is fixed on the railing with L type fixed card and goes up also fix tightly by being fixed on the fixed pulley (2,11) at movable pulley (4) on the cargo hook (6) and arm (1) top, rear portion.It is characterized in that: arm (1) directly uses L type fixed card (9) to be fixed on the building eaves (10), the cable drum (13) of band rocking handle (15) and power wheel (14) is fixed on the railing with L type fixed card (16), the bent angle of fixed card (9,16) is the 45-90 degree, and adjusting Luo Ding (18,17) and pad are arranged.
