Abstract
The utility model relates to a hoisting tri-magnification rope winding olecranon-shaped arm head of a moving arm tower crane, belongs to the technical field of construction engineering machinery and aims at solving the technical problems of a lifting hook pulley group of the existing moving arm tower crane that a steel wire rope is apt to deform and damage, hoisting magnification changing is difficult, high altitude operation is large in danger, the hook is apt to twist and the like. The hoisting tri-magnification rope winding olecranon-shaped arm head is characterized in that an arm end guide pulley (3) is arranged at the middle position of an arm head lower layer plane (20) close to the arm head end, and an arm end straightener (7) is arranged at the middle position of the arm head lower layer plane (20) far away from the arm head end. Upper layer web rods (12) are symmetrically arranged on two sides of a reinforced rod (11) of an upper layer plane (10). A hoisting steel wire rope (4) winds a hook pulley group (5), is pulled to the end of a hoisting arm, winds the guide pulley (3) and is pulled to the hook position, and the hoisting steel wire rope (4) and a hook straightener (6) are connected in pivoting mode.
Description
Technical field
The utility model patent relates to the constructional engineering machinery technical field, particularly the three multiplying power wiring olecranon-like arm heads that hoist of arm tower crane.
Background technology
The existing tower lifting of swing arm hoist the lifting hook pulley group adopt can swing with the jib vertical suspension bracket in plane that hoists, its principle is: hoist rope is by after the walking around of arm end leading sheave, but move into again swing hanger after moving into the sister block group of lifting hook pulley group, be fixed on the straight device of reason of arm end after moving into again the single-sheaved block group of lifting hook pulley group, realize hoisting four multiplying powers.When being converted to two multiplying powers such as need, but need with the swing hanger of arm end get hang after, the straight device of reason of arm end is positioned on the limit of arm end, hoist rope is by after the walking around of arm end leading sheave, after moving into the sister block group of lifting hook pulley group, raising line is fixed on the straight device of reason of arm end, realizes hoisting two multiplying powers.
Mainly there is following shortcoming in the existing tower lifting of the swing arm lifting hook pulley group that hoists:
1, raising line will reverse 90 ° at the leading sheave place, accelerates the deformation failure of steel rope;
2, hoist zoom rate difficulty, high-altitude application is dangerous large;
3, during the superelevation lifting altitude, two sheave shafts are apart from little, and suspension hook is easily beaten strand.
Summary of the invention
The utility model is intended to solve the existing tower lifting of the swing arm lifting hook pulley group that hoists and exists the dangerous large and suspension hook of the yielding destruction of steel rope, the zoom that hoists rate difficulty, high-altitude application easily to beat the technical matterss such as strand, but so that the easily arm tower crane three multiplying power wiring olecranon-like arm heads that hoist of a kind of actv. prevention suspension hook wire rope twisting, prolonging service life of steel wire, the conversion of the zoom that hoists rate to be provided.
The purpose of this utility model is achieved through the following technical solutions.
The arm tower crane of the present utility model three multiplying power wiring olecranon-like arm heads that hoist, arm end leading sheave 3 is located at the midway location of layer plane 20 nearly arm headends under the arm head, and the arm end is managed the midway location that straight device 7 is located at layer plane 20 arm ends far away under the arm head; The monosymmetric upper strata web member 12 that is provided with of the stirrup 11 of upper layer plane 10; Hoist rope 4 is walked around lifting hook pulley group 5, is pulled to the crane arm end and walks around arm end leading sheave 3 and be pulled to the suspension hook place again, and hoist rope 4 and suspension hook are managed straight device 6 sell mutually and connect.
The arm tower crane of the present utility model three multiplying power wiring olecranon-like arm heads that hoist, wherein said arm end is managed straight device 7 belows and is provided with overhauling nacelle.
The hoist beneficial effect of three multiplying power wiring olecranon-like arm heads of the utility model arm tower crane:
1. the conversion of 1,2,3 multiplying powers easily can realize hoisting;
2. lifting mechanism rope capacity deficiency and the long shortcoming of hoisting time when having solved arm tower crane superelevation lifting altitude;
3. solved the little shortcoming of general tower horn head assembly pulley wheelbase, make movable arm tower crane when the superelevation lifting altitude sheave shaft apart from increasing, but the problem of actv. prevention suspension hook wire rope twisting occurs.

The specific embodiment
The utility model detailed structure, application principle, effect and effect with reference to accompanying drawing 1-7, are explained by following embodiment.
The arm tower crane of the present utility model three multiplying power wiring olecranon-like arm heads that hoist, arm end leading sheave 3 is located at the midway location of layer plane 20 nearly arm headends under the arm head, and the arm end is managed the midway location that straight device 7 is located at layer plane 20 arm ends far away under the arm head; The monosymmetric upper strata web member 12 that is provided with of the stirrup 11 of upper layer plane 10; Hoist rope 4 is walked around lifting hook pulley group 5, is pulled to the crane arm end and walks around arm end leading sheave 3 and be pulled to the suspension hook place again, and hoist rope 4 and suspension hook are managed straight device 6 sell mutually and connect.The arm end is managed straight device 7 belows and is provided with overhauling nacelle.
During specific works, at first start lifting mechanism 1, emit hoist rope 4, traction hoist rope 4 passes arm end leading sheave 3 above crane arm support assembly pulley 2.Continue to emit hoist rope 4, allow hoist rope 4 drop down onto ground, prepare to install suspension hook.
As shown in Figure 5, cover of wedge and the suspension hook of hoist rope 4 ends are managed straight device 6 usefulness bearing pin pins even and put on spring cotter, be 1 multiplying power state this moment;
As shown in Figure 6, if will use 2 multiplying power work, then hoist rope 4 is walked around lifting hook pulley group 5, be pulled to the arm end and manage straight device 7 places and with bearing pin hoist rope 4 and arm end are managed straight device 7 pins and connect and put on spring cotter;
As shown in Figure 7, if will use 3 multiplying power work, then hoist rope 4 is walked around lifting hook pulley group 5, be pulled to the crane arm end and walk around arm end leading sheave 3, be pulled to again the suspension hook place and with bearing pin hoist rope and suspension hook managed straight device 6 pins even and put on spring cotter.
In sum, the utility model arm tower crane three multiplying power wiring olecranon-like arm heads that hoist, but actv. prevention suspension hook wire rope twisting, prolonging service life of steel wire, and have the technical characterstics such as the conversion of the zoom of hoisting rate is convenient.
