Embodiment Construction

[0018] As shown in Fig. 1, Fig. 2 and Fig. 3, a hoisting and lifting device for a steel ladle is composed of a mechanism platform 1, a hoisting mechanism 2, a winding wire rope 4 and a sling 3. The hoisting mechanism 2 is installed on the mechanism platform 1, and the winding wire rope 4 is connected with the ladle hanger 3 through the reel 203, the fixed pulley block 204, the movable pulley block 301.

[0019] The hoisting mechanism 2 is composed of two motors 201 , a speed reducer 202 , a reel 203 , four fixed pulley blocks 204 , a wire rope fixed end 205 and a brake 208 . The two motors 201 are respectively connected to the input shafts of the two reducers 202 through the two couplings I 206, and the output shafts of the two reducers 202 are connected at one end through the coupling II 207 to realize the mechanical synchronization of the two reels And a single motor works, and the other end drives two drums 203 respectively to realize the lifting and lowering of the ladle. ...

Abstract

A hoisting device of a steel ladle relates to hoisting and transporting machinery. The hoisting device of the steel ladle of the prior art adopts a hydraulic lift device and has the shortcomings of complicated structure, high manufacturing cost and difficult maintenance and repair. The invention consists of a plain stage of the mechanism, a raising mechanism, a wound wire rope and a hanger, wherein, the raising mechanism is arranged on the plain stage of the mechanism, the wound wire rope is connected with the hanger of the steel ladle by a wound roll, a fixed assembly pulley and a movable assembly pulley. The invention adopts the prior raising mechanism of a crane to replace the hydraulic lift device, thereby having the advantages of simple structure, safe and reliable operation, convenient maintenance and repair and low cost.

Description

technical field [0001] The invention belongs to hoisting and transporting machinery, in particular to a steel ladle suspender and a hoisting mechanism. Background technique [0002] At present, when performing RH vacuum oxygen treatment on molten steel in the smelting industry, a hydraulic jacking device is usually used to lift the ladle to a certain height, and then the molten steel is vacuum treated through the RH vacuum tank. The hydraulic jacking device of this ladle has complex structure, high cost, difficult repair and maintenance. Contents of the invention [0003] The object of the present invention is to provide a ladle hoisting device for the shortcomings of the prior art, which has the advantages of simple structure, safe and reliable operation, convenient maintenance and low cost. [0004] The present invention adopts the traditional crane lifting mechanism to replace the hydraulic jacking device in the prior art, so as to realize the lifting of the ladle. Th...
