Detailed Description
The following description is made with reference to the accompanying drawings and examples, but not to be construed as limiting the invention.
Example (b):
as shown in fig. 1-3, a tool special for hoisting a large generator motor rotor comprises a balance beam frame 1 with an upper opening and a lower opening, wherein a positioning sleeve 2 connected with a rotor 5 is arranged in the center of the balance beam frame 1, positioning shafts 21 are symmetrically arranged on the outer sides of the positioning sleeves 2, positioning grooves 11 for the installation of the positioning shafts 21 and the rotation connection with the positioning shafts 21 are formed in the wall surface of the balance beam frame 1, hanging rods 3 connected with hooks of a bridge crane are arranged at two ends of the balance beam frame 1, the hanging rods 3 are in threaded connection with the balance beam frame 1, and a hand wheel 31 is connected with one end of each hanging rod 3 extending out of the balance beam frame 1.
The locating sleeve 2 comprises a dust cover 22, a bearing 23, an annular pressing plate 24 and an annular clamping plate 25 are sequentially arranged in the dust cover 22 from bottom to top, and the upper end of the rotor 5 penetrates into the locating sleeve 2 to be rotatably connected with the bearing 23, so that the rotor can be conveniently rotated after being hoisted, and the installation position of the rotor can be adjusted.
The outer end of the positioning shaft 21 passes through the positioning groove 11 and is connected with a retaining ring 26, and a gasket is arranged on one side of the retaining ring 26 close to the balance beam frame 1. The connection stability of the positioning shaft is improved.
The balance beam frame 1 is hollow, a reinforcing plate 12 is arranged in the hollow part, and a through groove 13 is formed in the reinforcing plate 12. On the basis of enhancing the strength of the balance beam frame 1, the weight of the balance beam frame 1 is reduced, and the hoisting is convenient.
The pointer 4 is arranged in the center of the outer wall of the balance beam frame 1, the pointer 4 is connected with the balance beam frame 1 in a rotating mode, a scale 41 fixed with the outer wall of the balance beam frame 1 is arranged below the pointer 4, and the pointer 4 is aligned to the middle position of the scale 41 in the horizontal state of the balance beam frame 1.
The working principle is as follows: after two bridge cranes are combined, the hooks of the bridge cranes are embedded into the balance beam frame 1 and correspond to the hanging rods 3, the hand wheels 31 are rotated, the hanging rods 3 penetrate the hooks inwards to lock the hooks, the hooks are stably and firmly hooked with the hanging rods 3, the stable connection between the hooks and the balance beam is guaranteed, the hooks are prevented from being separated from the balance beam during hoisting, and the hoisting safety is improved. The rotor 5 is connected with the balance beam frame 1 through the positioning sleeve 2, so that the integral hoisting structure is stable, the operation is convenient, the connection is firm, and the hoisting safety coefficient is high; because the position sleeve 2 is connected with the rotation of the balance beam frame 1 through the positioning shaft 21, the rotor 5 can be guaranteed to be always kept in a vertical state in the hoisting process, the phenomenon of shaking is not easy to occur, the hoisting stability is strong, the damage to the rotor 5 caused by the deviation in the hoisting process is avoided, and the practicability is high.
