Abstract
The utility model relates to a hoist. The model is composed of a reel drum main axle, a big gear, a strap of the brake, a reel drum, a clutch propulsion device, an axle seat etc. The reel drum main axle is supported on the axle seat. The big gear is provided with the strap of the brake. The strap of the brake contacts with the inner cavity of the reel drum. The reel drum main axle is also provided with the clutch propulsion device. Because the reel drum is welded formed by adopting the low carbon alloyed steel material, the strength of the hoist is reinforced. Because the included angle alpha of the contacting of the strap of the brake and the inner cavity of the reel drum is designed to be: 12 degree <= alpha <= 16 degree, the model achieves the effects of the fast connecting and disconnecting under the functions of a top sleeve and the screw thread of the main axle of the reel drum.
Description
The utility model relates to a kind of winch in building and mining machinery field.
Relevant by retrieval patent documentation does not retrieve the winch identical with the utility model structure at present as yet.The kind of existing winch is more, differs from one another, because structural reason, generally when carrying out brake activation, be prone to phenomenons such as adjusting is not rapid, and structure benzene is heavy, work efficiency is low, bring a lot of inconvenience to construction, thus be necessary existing winch is improved, to satisfy actual needs.
The purpose of this utility model is will provide a kind of to have adjustment soon, a kind of winch in light weight, easy to use.
Technical characterictic of the present utility model is: considering to adjust soon, on the basis of dependable performance, be designed to a kind of winch of forming by spool spindle, big gear wheel, the strap of the brake, reel, hauling rope, escapement, clutch propelling unit, axle bed, described spool spindle is bearing on the axle bed, be respectively equipped with big gear wheel, reel on the described spool spindle, described escapement is packed on the reel, described big gear wheel is provided with the strap of the brake, the strap of the brake contacts with the inner chamber of reel, and the contacted angle α of the inner chamber of the strap of the brake and reel is 12 °≤α≤16 °; Also be provided with the clutch propelling unit on spool spindle, described clutch propelling unit is made up of pivoted arm, top cover, bearing, and pivoted arm links to each other with the top cover, and the top cover links to each other with spool spindle by screw thread.Described reel is the cylindrical shell that low-carbon alloy steel is welded into.
During use, under the driving of engine installation, deceleration through speed reduction gearing, transmission of power when needs promote, is handled the pivoted arm of clutch propelling unit to big gear wheel, this moment, the top was enclosed within the rotation of spool spindle screw thread, promote reel by bearing and contact,, thereby carry out work at the rotation lower mandrel member drive hauling rope scrolling of big gear wheel with the strap of the brake; When needs unclamp, handle the pivoted arm of clutch propelling unit, the top cover is moved to the direction away from reel, this moment, the reel and the strap of the brake unclamped.The contacted angle α of the inner chamber of the strap of the brake and reel is designed to 12 °≤α≤16 °, and its purpose is convenient to throw off and design-calculated fast.
The utility model has the advantages that: because reel adopts low-carbon alloy steel is that material is welded, thereby has strengthened the intensity of winch, helps the manufacturing of product, and has alleviated its weight; Because the contacted angle α of inner chamber of the strap of the brake and reel is designed to 12 °≤α≤16 °, under the effect of top cover and spool spindle screw thread, realized quick the connection and the effect of disengagement, improved work efficiency; Since rational in infrastructure, easy to use, so very big practical and popularizing value is arranged.
Below with reference to description of drawings embodiment of the present utility model:
Accompanying drawing is the structural representation of a kind of winch of the utility model.
With reference to accompanying drawing, the utility model is made up of spool spindle 1, big gear wheel 2, the strap of the brake 3, reel 4, hauling rope 5, escapement 6, clutch propelling unit 7, axle bed 8, and spool spindle 1 is bearing on the axle bed 8.Be respectively equipped with big gear wheel 2, reel 4 on the spool spindle 1; The cylindrical shell that described reel 4 is welded into for low-carbon alloy steel.Described escapement 6 is packed on the reel 4, and big gear wheel 2 is provided with the strap of the brake 3, and the strap of the brake 3 contacts with the inner chamber of reel 4, and the contacted angle α of inner chamber of the strap of the brake 3 and reel 4 is 12 °≤α≤16 °, and present embodiment α is 12 °.Also be provided with clutch propelling unit 7 on spool spindle 1, clutch propelling unit 7 is made up of pivoted arm 9, top cover 10, bearing 11, and pivoted arm 9 links to each other with top cover 10, pushes up to overlap 10 and link to each other with spool spindle 1 by screw thread.
