Abstract
The utility model provides a special lifting appliance for lifting a main shaft in a balancing manner. The lifting appliance comprises a bearing flange plate, wherein the bearing flange plate is fixedly connected with a web plate through a fixed bolt, a flying ring and unthreaded holes are formed in the upper end of the web plate, an adjusting screw rod is arranged at the lower end of the web plate, and the adjusting screw rod is provided with an adjusting nut. According to the lifting appliance, the operation is simple, the use is convenient, the lifting time is shortened, and the work efficiency can be greatly improved.
Description
Technical field
The utility model belongs to technical field of wind power generating equipment, relates in particular to a kind of special hanger of balance lifting main shaft.
Background technology
In the wind-powered electricity generation industry, general main shaft, when being assembled, need to be installed to main shaft on mainframe together with bearing, the level that will keep main-shaft axis in the process of installing, but because the size of main shaft is larger and weight ratio is heavier, therefore, cause the assembling difficulty, and have potential safety hazard.The method of existing assembling main shaft is generally to be banded on main shaft with suspender belt, under the prerequisite that keeps main shaft to be horizontal, main shaft is installed on mainframe together with bearing.The shortcoming of this assembly method is that in assembling, due to the obstruction of suspender belt, main shaft can not once just be seated, and is difficult to keep the balance of main shaft in the process of assembling.
Summary of the invention
The utility model provides the special hanger of a kind of balance lifting main shaft, solved the shortcoming that the hanging method in the background technology can not keep the balance of main shaft.
The technical solution of the utility model is achieved in that a kind of special hanger of balance lifting main shaft, comprise the bearing flange dish, the bearing flange dish is fixedly connected with by bolt of rear end plate with web, and the web upper end is provided with suspension ring and unthreaded hole, lower end is provided with adjusting screw(rod), and adjusting screw(rod) is provided with setting nut.
The beneficial effects of the utility model are: the utility model is simple to operate, easy to use, has reduced the lifting time, has greatly improved work efficiency.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is birds-eye view of the present utility model.
Part explanation: 1, suspension ring, 2, bolt of rear end plate, 3, setting nut, 4, the bearing flange dish, 5, adjusting screw(rod), 6, web, 7, unthreaded hole.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is further described: a kind of special hanger of balance lifting main shaft, comprise bearing flange dish 4, bearing flange dish 4 is fixedly connected with by bolt of rear end plate 2 with web 6, web 6 upper ends are provided with suspension ring 1 and 5 unthreaded holes 7, alignd with the unthreaded hole 7 on web 6 in hole on main shaft, fix main shaft with bolt, lower end is provided with adjusting screw(rod) 5, adjusting screw(rod) 5 is provided with setting nut 3, on adjusting screw(rod) 5, be threaded, coordinate with setting nut 3, can regulate the balance of suspender whole device when the lifting main shaft
The crane whole device that plays, move to the front end of main shaft, the close spindle flange dish 4 of web 6 of suspender, fix main shaft and suspender with bolt of rear end plate 2, slowly suspender is upwards lifted to a segment distance, the rotation setting nut 3, make whole device in state of equilibrium, crane continues mobile main shaft, is assembled.
