Abstract

The utility model discloses a light crane which is formed by that a rotary disk (4), a crown block, a suspended arm seat (7), a horizontal rotary device (2), a machine set case (9), a driving disk (10), a lower rotary disk (11) are arranged on a suspender (1) in order, and the upper rotary disk (4), the horizontal rotary device (2) and the lower rotary disk (11) are connected and fixed on a building body (13) by a connecting piece; a suspension system is made of wire rope and is composed of a reel drum on the machine set case (9), the suspended arm seat (7), the suspender (1), the suspended arm (3) and a pulley on a suspended hook (17), and the utility model is arranged at one time and can be used in the construction for two to three floors; the crane can be operated by man in a suspend basket or on the building, the utility model has the advantages of handiness, practicality, low cost, and if the utility model is used with transport vehicles, the effect is better.

Description

Portable crane

The utility model belongs to elevator machinery, is applicable to building engineering construction.

The weight-lifting equipment kind of building engineering employing both at home and abroad is more at present, big-and-middle-sized crane structure complexity, cost height, and place and surrounding environment need possess corresponding condition during use.Small-sized it can only do vertical lifting as " solely bar hangs ", is applicable to the building that three floors are following, and hanging object needs manpower to pull just and can put in place; The patent No. that can manage it is 92212949.5 " external climbing tower crane ", and it is light that it has a complete machine, is not subjected to the advantages such as restriction of place and climb altitude during use; But the body of the tower bottom need be fixed on the building body, and is that single face is stressed, and top needs counterweight, will use climbing devices such as winch, hydraulic actuating cylinder, cucurbit auxiliary when climbing, the installing/dismounting inconvenience.

The purpose of this utility model is to provide a kind of comformability strong, easy for installation, and cost is low, does not need the portable crane of counterweight during use.When high level uses, can adopt hanging basket, hanging ladder to install.

Its objective is such realization: fuselage by suspension rod, horizontally rotate device, arm, arm seat, top rotary table, fixed pulley, unit case, drive plate, lower rotary table and form.Top rotary table, fixed pulley, arm seat, horizontally rotate device, unit case, drive plate, lower rotary table and be contained on the suspension rod successively from top to bottom, top rotary table, horizontally rotate device and lower rotary table and be fastened on the building body with attaching parts, tackling system is made of by the pulley on unit case, arm seat, suspension rod, arm, the suspension hook hoisting wirerope.

This hoisting crane is that multiaspect is fixed on the building body, install once and can use for 2-3 floor construction, as exterior plaster when from top to bottom constructing in doing, only top rotary table (4) and lower rotary table (11) are fixed on to build on the body (13) and can carry out work with attaching parts (8), (15), (16).The people can in the hanging basket or the building body on manipulating crane.Light, practical, cost is low, if better with the supporting result of use of transport trolley.

Describe an embodiment of the present utility model in detail below in conjunction with accompanying drawing.

Fig. 1 is a front view of the present utility model.

Fig. 2 is the A-A cutaway view that horizontally rotates device (2).

Fig. 3 is that the utility model is contained in ground scheme drawing.

With reference to Fig. 1, suspension rod (1) is made up of two steel pipes of thickness, and the internal diameter of extra heavy pipe is slightly larger than the external diameter of tubule, equidistant hole is arranged for Telescopic Fixed usefulness on the bar.Fixed pulley is equipped with on suspension rod (1) top, and top rotary table (4) is equipped with on the top, and lower rotary table (11) is equipped with in the bottom, and suspension rod (1) is rotatable.Horizontally rotate device (2) as Fig. 2, square tube cover (20), three groups of bearings (21), prong portion are housed in forked standard (19) has fork buckle (22) composition, the middle part that is contained in suspension rod (1) is used for preventing the inclination of suspension rod, square tube cover (20) can be removed use if suspension rod (1) is a round steel pipe, also available annulus replaces device (2).Arm (3) rear end is equipped with arm seat (7) and is connected with axle, front end is equipped with the fixed pulley group, and wheel shaft is connected with an end of iron chains, and the other end of iron chains is connected with the fixed pulley axis on suspension rod (1) top, be used for controlling arm (3) and can only drop to certain position, upwards weight can be lifted the suspension rod top.Arm seat (7) is fixed on the suspension rod (1), and pulley is equipped with in the outer end of arm seat (7), and its sheave shaft is equipped with two inclined to one side iron (6) other ends and suspension rod upper sheave axle connects and composes the working face that triangle is promptly rolled up a machine.

Unit case (9) is welded with steel plate, is fixed on the bottom of suspension rod (1) and arm (3) on same plane, the elevator unit is housed on the unit case (9) and horizontally rotates unit.The elevator unit is made up of reel, retarder, drg, engine; Horizontally rotate that unit is meshing by little bearing pin and retarder, drg, engine, form.Drive plate (10) is rotated around big gear wheel (being fixed on above the lower rotary table) by chain by little gear wheel, makes circular movement thereby drive body.Directed attaching parts (5) and (8), (12), (14), (15), (16) respectively with top rotary table (4), horizontally rotate device (2) and lower rotary table (11) and be fastened on and build on the body (13).

Hoisting wirerope (18) one ends are fixed on the reel, and the other end is successively by the pulley on arm seat (7), suspension rod (1), arm (3), the suspension hook (17), and tackling system is formed in the upper end that is fixed on inclined to one side iron (6) behind the pulley of arm (3) outer end of unrolling again.

Fig. 3 stands in fuselage on the ground with cover pipe connections (23), (24), with directed attaching parts fuselage and building body is connected and fixed again.
