Abstract

The invention discloses a self-hoisting device and a self-hoisting method of dismounting members of a tower crane, relates to the technical field of construction crane machinery, and in particular belongs to the self-hoisting device and the self-hoisting method of the dismounting members of the tower crane. The self-hoisting device consists of a power mechanism, a pulley block and a stabilizing mechanism. The self-hoisting device is characterized in that the power mechanism consists of a crane motor (1) and a winch (2) of the tower crane self; the stabilizing mechanism refers to a tower cap (8) and a tower arm (9) of the tower crane as well as a fluke (6) for fixing the tail end of a steel wire rope; the pulley block comprises two fixed pulleys (5) and a movable block (4); the fixed pulleys are fixed on the tower cap; the movable block is linked with a hook; and the steel wire rope (3) is drawn out from the winch, comes around the pulley block and is fixed on the tower arm through the fluke. The self-hoisting device has the beneficial effects of simple structure and low investment cost, and is convenient to operate, safe and efficient.

Description

Tower crane dismounting parts are from device for hoisting and method
Technical field
The present invention relates to the construction hoisting machinery technical field, belong to especially a kind of tower crane dismounting parts from device for hoisting and method.
Background technology
Along with the progress of Building technology, the floor of building is all generally higher now, and it is more and more that tower crane uses in constructions work.Maintenance task to tower crane is also more and more heavier, the particularly replacing of cat head facility such as rotary system, because volume is big, heavy, working space is limited, and dismounting and handling are difficult to carry out.At present, at the dismounting of similar large component, method commonly used has: carry out thin portion earlier and disassemble, carry out the loose mail lifting again, mainly rely on manpower or manual finishing, its operation process complexity is loaded down with trivial details, lacks safety control; Perhaps, lift by other full-sized car hoisting crane, prepare long in time limitly, the hiring of equipment cost is higher.
Summary of the invention
Purpose of the present invention namely is to provide a kind of tower crane dismounting parts from device for hoisting and method, to reach safe and efficient, lower-cost purpose.
Tower crane dismounting parts provided by the present invention are made up of actuating unit, assembly pulley and stabilizing mechanism from device for hoisting, it is characterized in that, actuating unit is made 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, is fixed on the tower arm by anchor fluke.
Tower crane dismounting parts provided by the present invention is characterized in that from hanging method, comprise the steps:
Step 1, Lift-on/Lift-off System is built: utilize tower crane own bridge motor and winch, steel rope is involved from winch, walk around by two fixed pulleys and the assembly pulley that movable pulley constitutes, then, utilize anchor fluke that the steel rope end is fixed on the tower arm;
Step 2, disassemble: utilize and will treat that manually Awaiting Parts decomposes on the tower crane main body, system is hung on the suspension hook that movable pulley connects in the above-mentioned Lift-on/Lift-off System as the lifting object;
Step 3 hangs: start and control tower crane bridge motor and winch, can the handling of lifting object to ground;
Step 4, lifting: start again and control tower crane bridge motor and winch, will be through the parts of maintenance as the lifting of lifting object to original height, utilization is manually reinstalled and is got final product.
Tower crane dismounting parts provided by the present invention are from device for hoisting and method, take full advantage of 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 finish the handling work of dismounting parts voluntarily, have good effect simple in structure, easy and simple to handle, safe and efficient, that input cost is low.
Description of drawings
Fig. 1, structural representation of the present invention;
Fig. 2, working state schematic representation of the present invention.
The specific embodiment
As shown in Figure 1, tower crane dismounting parts provided by the invention are made up of actuating unit, assembly pulley and stabilizing mechanism from device for hoisting.Wherein, actuating unit is made of bridge motor 1 and winch 2, all adopts the tower crane existing equipment, without any need for transforming and change.Described assembly pulley is made up 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 present invention utilizes tower crane self to have dexterously, again erect another Lift-on/Lift-off System, in use, the control bridge motor drives winch, can realize rising and the decline of object by steel rope and assembly pulley, less demanding to the operation place, therefore, it is low to have cost, simple in structure, easy to operate and characteristic of strong applicability.
In addition, as shown in Figure 2, for prevent from hanging with hoisting process in lifting object 11 collide with tower crane fuselage 7 or hang and draw, in above-mentioned step 3, step 4, twine hauling rope 10 on the lifting object, by the tractive of hauling rope, lifting object and tower crane fuselage are maintained a certain distance.
