detailed description

In order to make the purpose, technical solution and advantages of the utility model more clear and definite, the utility model will be further described in detail below with reference to the accompanying drawings and examples.

Referring to Fig. 1 to Fig. 3, the utility model provides a special crane for soft hook type aluminum profiles, including a bridge frame 1, a lifting main machine 2 and an operating frame 5, and the bridge frame 1 consists of two main girders 11 and two end girders 12 The two end beams 12 are respectively connected with the ends of the two main beams to form a square frame, the main beam 11 and the end beam 12 are connected by bolts, and the end beam 12 is bent into a U-shaped groove with a steel plate body, and the main girder 11 is a box girder structure welded by four steel plates. The lifting main machine 2 is symmetrically arranged at both ends of the top of the main beam 11, the operating frame 5 is arranged at the bottom of one end of the main beam 11, and an operating room 3 is arranged at the bottom of the operating frame 5, and the operating room 3 and the operating frame 5 are integrally arranged, wherein the lifting main machine 2 includes a machine base 21, a motor 22, a reducer 23, a brake 27, a reel 24, a wire rope 25 and a hook 26, and the machine base 21 is fixedly connected to the top of the main beam 11 , the motor 22 is arranged on the machine base 21, because the working environment of the motor 22 is relatively poor, the temperature is high, and frequent starting and stopping are required in the work, so the motor 22 selects a YZ type squirrel-cage motor for use, and the insulation level of the motor is high. It can adapt to start and stop within 300 times per hour. The output shaft of the motor 22 is connected to the input shaft of the speed reducer 23 through a gear brake wheel coupling, and the brake 27 of the brake motor is arranged outside the gear brake wheel coupling, and the output end of the speed reducer 23 is connected to a speed reducer. One end of the reel 24 is connected to a reel flange (not shown in the figure), and the reducer flange and the reel flange are connected by bolts. A wire rope 25 is wound on the reel 24 , and the end of the wire rope 25 is connected with a hook 26 .

The crane operator turns on the motor 22 of the main machine 2 through the control system in the operating room 3, and the motor 22 transmits the power to the reducer 23 through the output shaft, and after the deceleration and torque increase of the reducer 23, the power is transmitted to the reel through the flange 24. The reel 24 rotates so that the wire rope 25 wound on the reel 24 can move up and down, and the hook 26 connected to the end of the wire rope 25 can work up and down to lift heavy objects.

In this embodiment, a tie rod 4 is connected between the two symmetrically arranged hooks 26 , and the tie rod 4 can fix the distance between the hangers 26 and prevent the hangers 26 from swinging.
