Detailed ways

In order to make the technical means, creative features, goals and effects achieved by the utility model easy to understand, the utility model will be further elaborated below in conjunction with specific embodiments.

As shown in Figures 1 to 4, a rope guide device on a lifting device includes a casing 10, and a lifting drum 1 driven by a motor is installed inside the casing 10, and the surface of the lifting drum 1 is spiral A circle of reel grooves 4 are engraved in a circle, the size of the reel groove 4 matches the steel wire rope 2, and the steel wire rope 2 can just be snapped into the reel groove 4.

Wherein, two smooth polished rods 8 are also installed inside the casing 10, and are installed in the casing 10 parallel to the hoisting reel 1, and a rope guide 7 is set up between the two polished rods 8, and the rope guide 7 mainly includes an arc Sheet 11, the two ends of the arc sheet 11 are set on the polished rod 8 through a connector 12 to slide left and right; the inner surface of the arc sheet 11 is also provided with three rope guide threads 9, and the specifications of the rope guide thread 9 are the same as those of the reel. The slots 4 are matched and fit into the drum groove 4 completely, and are driven by the rotation of the lifting drum 1; the surface of the arc piece 11 is provided with a rope hole 13 for the wire rope 2 to enter and exit.

Further, a straight rod 15 is additionally installed on the connecting head 12 installed under the arc piece 11, the two ends of the straight rod 15 are longer than the connecting head 12, and the inner wall of the housing 10 is respectively installed on the stroke corresponding to the left and right movement of the straight rod 15. A travel switch 14 is provided, and the travel switch 14 controls the switching circuit of the driving motor of the lifting reel 1.

Wherein, a rubber-coated pressure roller 3 is also installed inside the shell 10, a driven gear 6 is fixedly installed on one end of the rubber-coated pressure roller 3, a drum gear 5 is installed on one end of the lifting drum 1, and the drum gear 5 and the driven gear 6 mesh with each other, the rubber-coated pressure roller 3 is installed in the shell 10 through the central shaft, and is parallel to the lifting drum 1, and the rubber-coated pressure roller 3 is driven by the drum gear 5 through the driven gear 6 at the end with synchronous rotation.

First of all, it needs to be explained that the surface of the hoisting drum 1 of this type of lifting equipment can only be wound with a layer of steel wire rope 2, which is mainly used in some highly open hoisting places; in actual use, the driving motor drives the hoisting drum The drum 1 rotates forward, and the steel wire rope 2 is rewound to achieve lifting. At this time, the drum groove 4 on the surface of the lifting drum 1 will drive the arc piece 11 to move to the left, and the steel wire rope will be wound to the On the lifting drum 1, since the rope hole 13 is close to the position of the rope guide thread 9, and the arc piece 11 and the lifting drum 1 move synchronously, the steel wire rope 2 is wound around the winding drum in circles.
