Problems solved by technology
When in use, the hook lifts the corresponding steel ladle, and the steel ladle is lifted by moving the frame on the main beam. The existing problems of this electric hoist are: 1. The steel ladle is a special lifting object, and the steel ladle has high temperature The existing electric hoist only uses the wire rope to lift and transport the steel ladle. When the frame is moving on the main beam, the steel ladle will swing back and forth with the hook, especially when the frame just starts and moves in place. The swing is especially severe, the molten metal in the ladle may splash out, and the splashed molten metal may hurt people and cause accidents or damage the electric hoist; 2. When the frame is suddenly blocked by obstacles during the movement, the ladle will There will be a strong impact, and the possibility of molten metal splashing in the ladle will be greater

Embodiment Construction
[0028] An example of an electric hoist Figure 1~12 Shown: including the vehicle frame 2, the vehicle frame is provided with a lifting mechanism that can be lifted up and down and a traveling mechanism that is used to guide and move along the front and rear directions and is assembled on the corresponding main beam 13. The traveling mechanism includes a walking wheel 1 and a driving wheel to rotate drive unit. The hoisting mechanism includes a reel 3 and two steel wire ropes 4. Two overload limiters 16 corresponding to each steel wire rope and two rope wedge devices 17 respectively corresponding to each steel wire rope are arranged on the vehicle frame. The end rope head is connected to the corresponding overload limiter and then connected to the frame through the corresponding rope wedge device. The overload limiter is a Toledo overload limiter. The Toledo overload limiter has the characteristics of high precision. It is connected with the vehicle frame, and the lower end of...

The invention relates to an electric hoist which comprises a vehicle frame assembled on a corresponding main beam and used for performing guide movement along the front direction and the rear direction; the vehicle frame is provided with a lifting mechanism capable of lifting up and down; a lifting end of the lifting mechanism is connected with a hanging frame; the hanging frame is provided with a lifted object connection structure for connecting a corresponding lifted object; the vehicle frame is fixedly provided with a positioning frame having the tail end overhanging and extending downward; the lower end of the positioning frame is provided with a plug-in mounting and positioning structure, and the plug-in mounting and positioning structure is provided for plug-in mounting of the hanging frame from down to up and then is used for stopping cooperation with the corresponding side face of the hanging frame so as to limit the hanging frame to move front, back, right and left. The invention provides the electric hoist which can achieve smooth and steady lifting of the lifted object.
Description
technical field [0001] The invention relates to an electric hoist in the lifting field. Background technique [0002] As an ideal lifting equipment, the electric hoist is often used in daily production and life, and when the electric hoist is used in some special fields, it needs to have special functions. In the field of metallurgy, electric hoists are often used to lift ladles. The electric hoists used in the existing metallurgical field are such as the "metallurgical casting wire rope electric hoist" disclosed in Chinese patent document CN201186858Y. The vehicle frame on the corresponding main girder is provided with a hoisting mechanism that can be lifted up and down. The hoisting end of the hoisting mechanism is connected with a hook, and the hoisting mechanism includes a drum wound with a wire rope. When in use, the hook lifts the corresponding steel ladle, and the steel ladle is lifted by moving the frame on the main beam. The existing problems of this electric hoist...
