Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

The utility model provides a hoisting device for transporting goods from a fan cabin as shown in figures 1-4, which comprises a fan, a self-climbing crane and a traction winch 9;

as shown in fig. 1, a traction winch platform 11 is fixedly arranged at the bottom of a traction winch 9, a fan comprises a fan tower 1, a fan cabin 2 and fan blades 17, the fan cabin 2 is fixedly arranged at the top of the fan tower 1, the fan blades 17 are arranged on the fan cabin 2, a cabin cover 15 is arranged at the top of the fan cabin 2, the self-climbing crane comprises a fixed seat 16, a first lifting winch 6 and a control box 8, the first lifting winch 6 and the control box 8 are fixedly arranged on the fixed seat 16 from left to right, and the traction winch 9 is fixedly arranged on the traction winch platform 11;

with reference to fig. 1 and 2, a first clamp 3 and a second clamp 4 are symmetrically disposed on one side of a fixing seat 16, a locking device 13 is fixedly disposed on one end of the first clamp 3, a second hoisting winch 12 is fixedly disposed on the top of the locking device 13, the first hoisting winch 6 is connected with the fan cabin 2 through a first hoisting wire rope 7, the second hoisting winch 12 is connected with the fan cabin 2 through a second hoisting wire rope 14, a traction winch 9 is connected with the fixing seat 16 through a traction wire rope 10, a power plug is disposed on one side of a traction winch platform 11 through a power cord, and a roller device which automatically contracts according to the diameter change of the tower is disposed on the locking device 13, when the utility model is used, the traction winch 9 applies a horizontal force to the fixing seat 16 to pull the fixing seat 16, and the first hoisting winch 6 and the second hoisting winch 12 apply a vertical upward force to the fixing seat 16, the mounting block 16, i.e. the self-climbing crane, is pulled upwards.

Meanwhile, the top of the fixed seat 16 is fixedly provided with a small-tonnage crane 5, the small-tonnage crane 5 is arranged on two sides of the first lifting winch 6 and the control box 8, the small-tonnage crane 5 adopts a lifting telescopic rotating suspension arm, the reason that the small-tonnage crane 5 is adopted is that the lifting capacity of a general large-tonnage crane is 100 tons, the dead weight is close to 100 tons, the self-climbing type is adopted, the size is large, the lifting winch needs to be made large, when the large-tonnage crane embraces the fan tower drum 1 to lift goods, the holding force on the fan tower drum 1 is large, the fan tower drum 1 needs to be strengthened in the drum wall and needs to be thickened, the cost is high, and the fan tower is not suitable for the existing fans which are installed in.

This practical theory of operation: when the utility model is used, firstly, a power plug is required to be connected with an external power supply to provide electric energy for each electrical appliance of the utility model, then as shown in figure 2, the first clamp 3 and the second clamp 4 are installed on the fan tower 1 and are locked by the locking device 13, and as the fan tower 1 generally gets thinner and thinner, the locking device 13 with the roller device which automatically contracts can be better fixed, then the first lifting winch 6 and the second lifting winch 12 are started to lift the fixed seat 16 and the small-tonnage crane 5, after lifting, the small-tonnage crane 5 is used to take off the cabin cover 15, then the small-tonnage crane 5 is used to lift the large-tonnage crane in a form of hoisting parts, the weight of each part of the large-tonnage crane is not more than that of the small-tonnage crane, the parts are lifted one by one, the small-tonnage crane 5 is assembled one by one, and finally, a large-tonnage crane (not shown in figure 4) is assembled, the large-tonnage crane is used for hoisting large parts in the fan cabin 2, such as about 50 tons of a generator of the existing fan and about 30 tons of a gear box, the large parts are replaced, the large-tonnage crane is used for hoisting the cabin one by one in a part mode, and the self-climbing crane is put back to the ground, so that the whole replacement work is completed.

Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications and variations can be made in the embodiments or in part of the technical features of the embodiments without departing from the spirit and the principles of the present invention.
