Embodiment Construction
[0008] Below the present invention will be further described in conjunction with the embodiment in the accompanying drawing:
[0009] Such as figure 1 As shown, it includes a motor 1, a gear coupling 2 with a brake wheel, a brake 3, a reducer 4, a reel gear coupling 5, a reel 6, a wire rope 7, a hook 8, and a bearing seat 9.
[0010] The present invention is driven by motor 1 (YZR (P) type hoisting motor). The motor 1 is connected to the high-speed shaft end of the reducer 4 through a coupling through a gear coupling 2 with a brake wheel. When working, the low-speed shaft of the reducer (QJRS horizontal hoisting reducer) 4 drives the reel 6, Roll up or release the wire rope 7, and pass through the pulley block 10 to make the hook 8 go up or down. The lifting is realized by changing the direction of the electric motor 1.
[0011] The present invention adopts the gear coupling 2 with compensation performance. In order to make the layout more convenient, increase the compensat...

The invention relates to a hoisting mechanism of a crane, in particular to an important mechanism in the crane for realizing the lifting of goods. The hoisting mechanism is characterized in that a motor is linked with the high-speed end of a speed reducer through a gear coupling with a brake wheel, a brake is mounted on a shaft of the speed reducer through the coupling with the brake wheel, the brake is electrically interlocked with the motor, a reel is linked with the low-speed end of the speed reducer through the gear coupling of the reel, the reel is mounted on a rotating shaft, the shaft end of the reel is mounted in a bearing in a bearing seat, one end of a steel wire rope is wound on the reel, and the other end is linked with a hanging hook group, thereby controlling the ascending or the descending of hanging hooks by regulating the motor. The hoisting mechanism has simple, compact and reasonable structure; as the hoisting mechanism is linked through the gear couplings with the compensation performance, the mounting is convenient; and the working is safe and reliable, and the production efficiency can be improved.
Description
technical field [0001] The invention relates to a hoisting mechanism of a crane, in particular, it is used to realize lifting and lowering of goods, and is an important mechanism in the crane. Background technique [0002] At present, many types of lifting mechanism devices are often used in the working process of portal cranes. Some lifting structure devices are difficult to manufacture and assemble, which wastes manpower and financial resources and greatly reduces work efficiency. Contents of the invention [0003] The purpose of the present invention is to overcome the above disadvantages, thereby providing a hoisting mechanism of a crane which is safe and reliable in operation, easy to manufacture, easy to maintain and repair, and can improve production efficiency. [0004] According to the technical solution provided by the present invention, the hoisting mechanism of the crane includes a motor, a gear coupling with a brake wheel, a brake, a reducer, a drum gear coupl...
