specific Embodiment approach

[0015] Below in conjunction with accompanying drawing, the present invention is described in further detail:

[0016] like figure 1 , 2 , 3, and 4, a generator stator 4 joint hoisting device of the present invention adopts the existing bridge crane 1 technology and transforms it, and utilizes the hoisting device to hoist more than the maximum rated lifting capacity of the bridge crane 1 generator stator 4.

[0017] Its specific structure comprises bridge crane 1, and bridge crane 1 comprises two main girders 1-2 and auxiliary hook reel, and is provided with main hook reel and driving motor across between two main girders 1-2. The trolley 1-1, a sky beam 2 that can move along the main beam 1-2 is also straddled between the two main beams 1-2, the sky beam 2 includes a cross beam 2-2, the sky beam 2 and the lifting trolley 1-1 Connecting rods are connected between them, the upper fixed pulley block 2-1 is arranged at the bottom of the sky beam 2, the pole beam 3 is horizontal...

Abstract

A combined hoisting device for a generator stator comprises a bridge crane and a beam. A connecting rod is connected between the beam and a lifting dolly; the bottom of the beam is provided with an upper pulley block; a carrying pole beam is horizontally arranged below a girder; a stator hoisting rope suspends below the carrying pole beam; one end of the top of the carrying pole beam is provided with an outer lug and an inner lug; an opening pulley is hung on the inner lug; the other end of the top of the carrying pole beam is provided with a guide pulley and a movable block; the outer lug hangs on a wire rope enwinding on a main hook drum; and the wire rope wound on the auxiliary hook drum rounds the opening pulley, the guide pulley and winds between the pulley block and the movable block. The invention has the beneficial effect that the device makes full use of the stereo space, uses load distribution, makes full use of a turbine house bridge machine, does not use large lifting equipment, and meets the needs for stator hoisting of the bridge machine. In addition, the device has the advanategs of simple tool, convenience for transportation, convenience for installation, quick putting in place, and cost saving.

Description

technical field [0001] The invention relates to a generator stator combined hoisting device. Background technique [0002] At present, in the construction process of electric power construction in my country, the hoisting process of the generator stator is the most complicated, with the highest risk factor and great influence, and is the key control point for the safety, quality and progress of unit construction. The selection and application of the hoisting scheme fully reflects the construction technology level of a construction company. The main factors that must be considered for the most feasible and optimized stator hoisting scheme are the internal and external layout of the main workshop, the status of the stator, the bearing capacity of the steel structure of the workshop, and the construction Machinery, driving specifications of the main workshop, construction period, economy, practicability, etc. Nowadays, most of the on-site stator hoisting uses large-scale hoist...
