Abstract
The utility model relates to the technical field of the building hoisting machinery and particularly belongs to a disassembled and assembled part self-lifting device and method for a tower crane. The disassembled and assembled part self-hanging device comprises a power mechanism, a pulley group and a stable mechanism and is characterized in that the power mechanism is composed of a lifting motor (1) and a winch (2) of the tower crane; the stable mechanism is composed of a tower cap (8) and a tower arm (9) of the tower crane and a fluke (6) fixed at the tail end of a steel wire rope (3); the pulley group comprises two fixed pulleys (5) and a movable pulley (4); the fixed pulleys are fixed on the tower cap; the movable pulley is connected with a hook; the steel wire rope (3) is pulled out from the winch, bypasses the pulley group, and is fixed on the tower arm through the fluke. The disassembled and assembled part self-lifting device has the positive effects of simple structure, convenience in operation, safety, efficiency and low input cost.
Description
Technical field
The utility model relates to the construction hoisting machinery technical field, belong to especially a kind of tower crane dismounting parts from device for hoisting.
Background technology
Along with the progress of Building technology, the floor of building now is all generally higher, and tower crane uses in constructions work more and more.Maintenance task to tower crane is also more and more heavier, the particularly replacing of the tower top facility such as rotary system, because volume is large, heavy, working space is limited, and dismounting and handling are difficult to carry out.At present, for the dismounting of similar large component, method commonly used has: first carry out thin section and disassemble, then carry out the loose mail lifting, mainly rely on manpower or manual completing, its operation process complexity is loaded down with trivial details, lacks safety control; Perhaps, by other full-sized car hoisting crane, lift, prepare long in time limitly, the hiring of equipment cost is higher.
Summary of the invention
The purpose of this utility model namely is to provide a kind of tower crane dismounting parts from device for hoisting, to reach safe and efficient, and lower-cost purpose.
Tower crane dismounting parts provided by the utility model, from device for hoisting, are comprised of actuating unit, assembly pulley and stabilizing mechanism, it is characterized in that, actuating unit consists of tower crane own bridge motor and winch; Described stabilizing mechanism refers to tower cap and the tower arm of tower crane, and the fixing anchor fluke of steel rope end; Described assembly pulley comprises two fixed pulleys and a movable pulley, and fixed pulley is fixed on the tower cap, and movable pulley connects suspension hook; Steel rope involves from winch, walks around assembly pulley, by anchor fluke, is fixed on the tower arm.
Tower crane dismounting parts provided by the utility model are from device for hoisting, take full advantage of the existence conditionses such as bridge motor, winch and tower cap that tower crane self has, tower arm, steel rope, again erect another Lift-on/Lift-off System, can complete voluntarily the handling work of dismounting parts, have good effect simple in structure, easy and simple to handle, safe and efficient, that input cost is low.
Description of drawings
Fig. 1, the utility model structural representation;
Fig. 2, the utility model working state schematic representation.
The specific embodiment
As shown in Figure 1, the tower crane dismounting parts that the utility model provides, from device for hoisting, are comprised of actuating unit, assembly pulley and stabilizing mechanism.Wherein, actuating unit consists of bridge motor 1 and winch 2, all adopts the tower crane existing equipment, without any need for transformation and change.Described assembly pulley is comprised of two fixed pulleys 5 and a movable pulley 4, and two fixed pulleys are fixed on the tower cap of tower crane, and the movable pulley below connects a suspension hook.Described stabilizing mechanism comprises anchor fluke 6, tower cap 8 and tower arm 9.Steel rope 3 stretches out from winch, walks around assembly pulley, and its end is fixed on the tower arm by anchor fluke.
The condition that the utility model utilizes tower crane self to have dexterously, again erect another Lift-on/Lift-off System, in use, control bridge motor and drive winch, can realize rising and the decline of object by steel rope and assembly pulley, less demanding to Active workings, therefore, have cost low, simple in structure, the easy to operate and strong characteristics of applicability.
In addition, as shown in Figure 2, the utility model in use, for prevent from hanging with hoisting process in lifting object 11 collide with or hang and draw with tower crane fuselage 7, can be wound around hauling rope 10 on the lifting object, by the tractive of hauling rope, lifting object and tower crane fuselage are maintained a certain distance.
