Description

Technical Field

[0001] The utility model relates to the technical field of scraper winches, and more specifically to a wire rope guide device for scraper winches. Background Art

[0002] The scraper winch is mainly used for ore handling and filling operations in underground pits or open pits in metal mines and other mines. Its working method is that the wire rope wound on the drum pulls the scraper bucket to make a reciprocating motion to rake the ore. Since the scraper winch does not have a wire rope guide device, the wire rope is often twisted onto the reverse drum, causing the wire rope to be frequently broken. Therefore, it is necessary to set a wire rope guide device on the scraper winch to realize the traction of the wire rope.

[0003] After searching, the utility model patent with announcement number CN219730396U discloses a wire rope guiding device for a rake winch, including a base, a ball screw is arranged on the base, a motor is arranged on the base to cooperate with the ball screw, a screw nut is arranged on the ball screw to cooperate with the ball screw, a fixed seat is arranged at the top of the screw nut, a lifting seat is arranged at the top of the fixed seat, a lifting adjustment component is arranged between the lifting seat and the fixed seat, a mounting frame is arranged at the top of the lifting seat, a square mounting frame is arranged at the top of the mounting frame, and guide rollers are rotatably installed on each frame of the mounting frame through bearings, and the edges of two adjacent guide rollers are close to each other. The device has good guiding performance for the wire rope, is easy to adjust the guiding position and height of the wire rope, and is flexible and convenient to use.

[0004] However, the above patents still have the following shortcomings: the ball screw is exposed to the outside, and dust and debris are easily attached to it, affecting the transmission with the screw nut, and the guide space surrounded by the four guide rollers is fixed, and the wire rope will move in the guide space, affecting the guiding effect. For this reason, we propose a wire rope guide device for a rake winch. Utility Model Content
