Description

Technical Field

[0001] The utility model relates to the technical field of electric winches, in particular to an electric winch lifting device used for vertical shaft sinking construction. Background Art

[0002] During the vertical shaft drilling construction process, as the depth of the vertical shaft drilling becomes deeper and deeper, it is necessary to use a lifting system to lift the excavated rock and soil to the ground and discharge it, and to lower the supporting materials into the well to form the shaft structure.

[0003] In the Chinese utility model patent application disclosure CN218478484U, an electric winch hoisting system for vertical shaft drilling construction is disclosed. Although the controller triggers the frequency converter to control each electric winch to perform hoisting operation at a set speed, and the speed of each electric winch is fed back in real time through the encoder to realize synchronous hoisting operation of multiple electric winches; when the bucket inclination angle exceeds the set adjustment angle, the controller triggers the frequency converter to control one or several electric winches to change the speed in real time to realize hoisting correction, so that the bucket inclination angle is less than the set adjustment angle; when the bucket inclination angle exceeds the set maximum angle at a certain moment, the controller triggers each electric winch to stop and sound an alarm; in addition, the tension of the wire rope is detected in real time by the tension sensor, and when the tension exceeds the set safety tension value, the controller triggers each electric winch to stop and sound an alarm, but the wire rope on the winch is used for a long time, the surface of the wire rope is rough after drying, the friction coefficient increases, and the friction force increases. This will result in the winch requiring greater power to overcome friction during operation, reducing the winch's working efficiency. The increased friction will lead to increased wear on the wire rope surface. Applying lubricating oil can effectively reduce friction and reduce wear. However, currently applying lubricating oil to wire ropes is rather troublesome and requires manual work by staff, which has the disadvantage of poor convenience. Utility Model Content
