Abstract
The utility model discloses a crane lifting mechanism capable of preventing a steel wire rope from reeling, which comprises a winding drum, wherein the top part of the winding drum is mounted on a cross beam of a crane through a walking gear; the outer side of the winding drum is externally connected with a reducer and a driving motor; the winding drum is provided with a winding drum shade with an opening; bearings are mounted at the left and the right ends of the winding drum shade, between which a rotating shaft is mounted; two winding drum hubs are mounted on the rotating shaft; a winding drum body is mounted on the outer sides of the winding drum hubs; a cable groove is formed in the winding drum body and is wound by the steel wire rope; one end of the steel wire rope penetrates the opening of the winding drum shade and extends perpendicularly downwards; and a hook is mounted at the end part of the steel wire rope. The lifting mechanism is characterized in that a guard ring is mounted on the inner wall of the winding drum shade and positioned at the outer end of the winding drum body; and the difference between the radius of the inner hole of the guard ring and the radius of the outer wall of the winding drum body is smaller than the diameter D of the steel wire rope. The lifting mechanism is simple in structure and convenient to use, and can effectively avoid that the steel wire rope is wound in the rotating shaft due to skew pulling and inclined hanging, resulting in stuck potential hazards, and accordingly the application safety is improved, and the equipment failure rate is greatly reduced.

Summary of the invention
The purpose of this utility model be exactly to solve traditional crane lifting mechanism in use occur easily askew skew to hang be involved in stuck in the rotating shaft, problem such as use is dangerous, equipment failure rate is higher and labor strength is bigger, a kind of crane lifting mechanism with the anti-roll function of steel rope is provided.
Concrete scheme of the present utility model is: improve at traditional crane lifting mechanism, it has reel, and the reel top is installed on the hoisting crane crossbeam by walking gear, the external retarder of reel one side and drive motor; This reel has the reel cover, the reel cover is provided with opening, bearing all is equipped with at the two ends, the left and right sides of reel cover, be coated with rotating shaft between the two bearings, be positioned at the reel hub that symmetric arrangement is housed in the rotating shaft in the reel cover, spool body is equipped with in the outside of reel hub, have the steel cable groove on the spool body, be wound with steel rope on the steel cable groove, the opening that an end of steel rope passes the reel cover extends vertically downward, and suspension hook is equipped with in the end of steel rope; It is characterized in that: guard collar is equipped with in the outer end that is positioned at spool body at reel cover inwall, and the difference S of the interior pore radius of guard collar and the exterior radius of spool body is less than the diameter D of steel rope.
Be positioned at the two bearings outer end described in the utility model in the rotating shaft end ring all is housed.
One end of rotating shaft described in the utility model stretches out the reel cover and links to each other with the output shaft of retarder by coupler.
The utility model is simple in structure, and is easy to use, steel rope can not occur askew skew to hang to be involved in cause stuck phenomenon in the rotating shaft, the safety of use improves greatly, equipment failure rate is lower greatly, has brought huge economic benefit to enterprise.
Description of drawings
Fig. 1 is front view of the present utility model;
Fig. 2 is the A-A amplification view of Fig. 1;
Fig. 3 is the I place enlarged view of Fig. 2.
Among the figure: 1-drive motor, 2-retarder, 3-coupler, 4-rotating shaft, 5-walking gear, 6-steel rope, 7-hoisting crane crossbeam, 8-reel, 9-suspension hook, 10-output shaft, 11-reel cover, 12-guard collar, 13-steel cable groove, 14-spool body, 15-opening, 16-reel hub, 17-bearing, 18-end ring.
The specific embodiment
Referring to Fig. 1, Fig. 2 and Fig. 3, the utlity model has reel 8, reel 8 tops are installed on the hoisting crane crossbeam 7 by walking gear 5, the external retarder 2 of reel 8 one sides and drive motor 1; This reel 8 has reel cover 11, reel cover 11 is provided with opening 15, bearing 17 all is equipped with at the two ends, the left and right sides of reel cover 11, be coated with rotating shaft 4 between the two bearings 17, be positioned at two bearings 17 outer ends in the rotating shaft 4 end ring 18 all is housed, and rotating shaft 4 one ends stretch out reel cover 11 and link to each other with the output shaft 10 of retarder 2 by coupler 3, be positioned at the reel hub 16 that symmetric arrangement is housed in the rotating shaft 4 in the reel cover 11, spool body 14 is equipped with in the outside of reel hub 16, have steel cable groove 13 on the spool body 14, be wound with steel rope 6 on the steel cable groove 13, the opening 15 that an end of steel rope 6 passes reel cover 11 extends vertically downward, and suspension hook 9 is equipped with in the end of steel rope 6; Particularly: guard collar 12 is equipped with in the outer end that is positioned at spool body 14 at reel cover 11 inwalls, and the difference S of the interior pore radius of guard collar 12 and the exterior radius of spool body 14 has namely constituted the utility model less than the diameter D of steel rope 6.
Because the difference S of the interior pore radius of guard collar 12 and the exterior radius of spool body 14 is less than the diameter D of steel rope 6, during concrete work, steel rope 6 is in case around the end to spool body 14, steel rope 6 can be blocked by guard collar 12, steel rope 6 can not take place be rolled into and cause stuckly in the rotating shaft 4, safety in utilization is improved.
