Abstract
The invention discloses a crane lifting mechanism with a steel wire rope rolling prevention function. The crane lifting mechanism comprises a rolling barrel, the top of the rolling barrel is mounted on a crane cross beam through a walking gear, one outer side of the rolling barrel is connected with a speed reducer and a drive motor, the rolling barrel comprises a rolling barrel hood which is provided with an opening, bearings are mounted at the left end and the right end of the rolling barrel hood respectively, a rotating shaft is mounted between the two bearings in a penetrating mode, two rolling barrel hubs are mounted on the rotating shaft, rolling barrel bodies are mounted outside the rolling barrel hubs respectively and are provided with steel wire rope grooves respectively, a steel wire rope is wound on the steel wire rope grooves, one end of the steel wire rope penetrates through the opening of the rolling barrel hood to extend downwards and vertically, and a hook is arranged at the end of the steel wire rope. The crane lifting mechanism is characterized in that protection rings are arranged on the inner wall of the rolling barrel hood and located at the outer ends of the rolling barrel bodies, and the difference S of the radius of an inner hole of each protection ring and the radius of the outer wall of each rolling barrel body is smaller than the diameter D of the steel wire rope. The crane lifting mechanism is simple in structure and convenient to use, effectively eliminates the potential safety hazards that the steel wire rope is clamped when the steel wire rope is obliquely pulled and lifted and rolled into the rotating shaft, and improves using safety, and the device failure rate is greatly lowered.
Description
Technical field
The present invention relates to crane facility technical field, especially a kind of crane lifting mechanism with the anti-roll function of steel rope.
Background technology
At present, traditional crane lifting mechanism has reel, and reel top is arranged on crane transverse beam by walking gear, the reel external retarder of one side and drive motor; This reel has reel cover, reel cover is provided with opening, bearing is all equipped with at the two ends, left and right of reel cover, between two bearings, be coated with rotating shaft, be positioned in rotating shaft the reel hub being arranged symmetrically with is housed in reel cover, spool body is equipped with in the outside of reel hub, on spool body, have steel cable groove, on steel cable groove, be wound with steel rope, extend vertically downward through the opening of reel cover one end of steel rope, and suspension hook is equipped with in the end of steel rope.The crane lifting mechanism of this conventional confguration in use steel rope easily occur askew skew to hang be involved in rotating shaft stuckly, use extremely dangerously, equipment failure rate is higher, need to often keep in repair, workman's labour intensity is larger.Therefore, designing a kind of crane lifting mechanism with the anti-roll function of steel rope that can address the above problem well is extremely necessary.
Summary of the invention
Object of the present invention be exactly to solve traditional crane lifting mechanism in use easily occur askew skew hang be involved in stuck in rotating shaft, use dangerous, the problem such as equipment failure rate is higher and labor strength is larger, a kind of crane lifting mechanism with the anti-roll function of steel rope is provided.
Concrete scheme of the present invention is: for traditional crane lifting mechanism, improve, it has reel, and reel top is arranged on crane transverse beam by walking gear, the reel external retarder of one side and drive motor; This reel has reel cover, reel cover is provided with opening, bearing is all equipped with at the two ends, left and right of reel cover, between two bearings, be coated with rotating shaft, be positioned in rotating shaft the reel hub being arranged symmetrically with is housed in reel cover, spool body is equipped with in the outside of reel hub, on spool body, have steel cable groove, on steel cable groove, be wound with steel rope, extend vertically downward through the opening of reel cover one end of steel rope, 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, 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.
Described in the present invention, in rotating shaft, be positioned at two bearings outer end end ring is all housed.
The one end of rotating shaft described in the present invention is stretched out reel cover and is connected with the output shaft of retarder by coupler.
The present invention is simple in structure, easy to use, steel rope there will not be askew skew to hang to be involved in rotating shaft cause stuck phenomenon, the safety of use improves greatly, equipment failure rate is greatly lower, to enterprise, has brought huge economic benefit.
Accompanying drawing explanation
Fig. 1 is front view of the present invention;
Fig. 2 is the A-A amplification view of Fig. 1;
Fig. 3 is the I place enlarged view of Fig. 2.
In figure: 1-drive motor, 2-retarder, 3-coupler, 4-rotating shaft, 5-walking gear, 6-steel rope, 7-crane transverse beam, 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 present invention has reel 8, and reel 8 tops are arranged on crane transverse beam 7 by walking gear 5, the reel external retarder 2 of 8 one side and drive motor 1, this reel 8 has reel cover 11, reel cover 11 is provided with opening 15, bearing 17 is all equipped with at the two ends, left and right of reel cover 11, between two bearings 17, be coated with rotating shaft 4, in rotating shaft 4, be positioned at two bearings 17 outer ends end ring 18 is all housed, and rotating shaft 4 one end are stretched out reel cover 11 and are connected with the output shaft 10 of retarder 2 by coupler 3, in reel cover 11, be positioned at the reel hub 16 being arranged symmetrically with is housed in rotating shaft 4, spool body 14 is equipped with in the outside of reel hub 16, on spool body 14, have steel cable groove 13, on steel cable groove 13, be wound with steel rope 6, extend vertically downward through the opening 15 of reel cover 11 one end of steel rope 6, 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, 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, has formed the present invention.
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 specific works, once steel rope 6 is around the end to spool body 14, steel rope 6 can be blocked by guard collar 12, steel rope 6 can not occur and be rolled into and in rotating shaft 4, cause stuckly, safety in utilization is improved.
The selection of size, specification and the material of drive motor 1 of the present invention, retarder 2, coupler 3, rotating shaft 4, walking gear 5, steel rope 6, crane transverse beam 7, reel 8, suspension hook 9, output shaft 10, reel cover 11, guard collar 12, steel cable groove 13, spool body 14, opening 15, reel hub 16, bearing 17 and end ring 18; can adjust according to actual needs; these adjustment there is no the change of substantive principle, all belong to protection scope of the present invention.
