Abstract
The utility model provides a portable crane which is mainly composed of a machine frame, a cantilever, a fixed pulley and a capstan engine. The utility model is characterized in that the machine frame is a ridge type Y-shaped support bracket, and the cantilever is fixed by a cross beam. Fixed pulleys are respectively fixed on the cross beam and the cantilever, and the capstan engine is arranged on the machine frame. A loading basket is hoisted by a hoisting rope of the capstan engine through a fixed pulley A and a fixed pulley B. The portable crane of the utility model has the characteristics of safety, easy operation, labor saving, great reduction of the labor strength, fast transportation, time saving, simple structure, easy assembly and disassembly, and light weight of the portable crane. The utility model is especially suitable for family fitment.
Description
Technical field
The utility model relates to a kind of hoisting crane, and is especially a kind of simple to operate, easy to carry, and detachable assembling is applicable to the house decoration portable crane.
Background technology
At present, hoisting crane mostly is swinging crane of bridge-type, tower, wall type or stationkeeping etc., and these weight-lifting equipment equipment investments are big, complex structure, heaviness, costs an arm and a leg, and generally is unsuitable for interior decoration.Therefore finishing material all is to shoulder by manpower hand half the circumference of the sleeve where it joins the shoulder to finish, and labour intensity is big and dangerous, does not have suitable device haul machinery to solve the difficult problem that finishing material is gone upstairs.
Summary of the invention
It is a kind of simple in structure that the purpose of this utility model is to provide, and mobile operation conveniently is convenient in disassembly and assembly, is applicable to the house decoration portable crane.
The purpose of this utility model is achieved in that it mainly is made up of frame, cantilever, fixed pulley, winch, it is characterized by frame is the chevron shaped supporting bracket of ridge type, the support below is fixed with connecting rod, crossbeam one end has latch structure, but cantilever mounted is fixed with fixed pulley A on crossbeam, and the end top that cantilever stretches out is fixed with fixed pulley B, winch places on the gantry base, and the derrick line of winch is sling after by fixed pulley A, fixed pulley B and carried a dress hanging basket; Fix a cantilever positioning rope on the cantilever, the rope other end is fixed on the crossbeam, and the length of positioning rope is adjustable, in order to regulate the height of cantilever.
Owing to adopted the chevron shaped supporting bracket of ridge type, good wind resistance is arranged in the utility model, anti-waving makes the lifting process more solid and reliable.
But also wheel-mounted on the frame of the present utility model as cardan wheel etc., is more suitable for operation like this, can remedy the non-retractable deficiency of cantilever.
Because winch places on the frame, makes frame increase deadweight, is located.If it is overweight to play weight, also can on frame, set up the counterweight hurdle, conduct oneself with dignity to improve with addition of weight in addition.

The specific embodiment
Adopt the portable crane shown in the accompanying drawing 1, gantry base is the four-wheel vehicle, four jiaos of places are fixed with the chevron shaped supporting bracket of ridge type, crossbeam one end has adjustable orifice plate 10, is used to the cantilever that is connected and fixed, and adjustable screw 11 also is used for fixing cantilever in addition, at the fixing fixed pulley A of the crossbeam other end, the end top that cantilever stretches out is fixed with fixed pulley B, and winch places on the gantry base, and the derrick line of winch is sling after by fixed pulley A, fixed pulley B and carried a dress hanging basket; Be fixed with the cantilever positioning rope on the cantilever, the rope other end is fixed on the crossbeam by adjustable screw 9, and the length of positioning rope is adjustable, in order to regulate the height of cantilever, also be equipped with the counterweight hurdle in the frame bottom, when the lifted weight preponderance, on the counterweight hurdle, add corresponding object.
During enforcement cantilever is extended outside window by window, weight is sling, frame is pulled to unload in the room with manpower by window again and gets final product.
Hoisting capacity 〉=150 kilogram, the lifting height can reach 75 meters, and hoisting speed can reach 15 meters/minute, and it is normal to operate steadily, and flexible operation is reliable.
The characteristics of portable crane of the present utility model are: safety, good operation, save labour power, and greatly reduced labour intensity, transportation is quick, save time, simple in structure, disassembly and assembly are convenient, the hoisting crane gross weight is extremely light, is convenient to mobile operation, is specially adapted to house decoration.
Claims (2)
1, a kind of portable crane, mainly form by frame, cantilever, fixed pulley, winch, it is characterized by frame is the chevron shaped supporting bracket of ridge type, the support below is fixed with connecting rod, and crossbeam one end has latch structure, but cantilever mounted, on crossbeam, be fixed with fixed pulley A, the end top that cantilever stretches out is fixed with fixed pulley B, and winch places on the gantry base, and the derrick line of winch is sling after by fixed pulley A, fixed pulley B and carried a dress hanging basket; Fix a cantilever positioning rope on the cantilever, the rope other end is fixed on the crossbeam.
