Description

Winch

The utility model relates to a kind of winch.

General winch is to be used for lifting or dilatory weight, for example the weight of eminence is slowly drop to lower or the weight of lower is risen to eminence, and twisted rope must be pulled out when no matter under any circumstance using, twisted rope is for loading weight, generally make by metal material, and have certain rigid, therefore, when after use, furling twisted rope, if twisted rope not loading does not have under the situation of tensile force, twisted rope can take place furl loose mixed and disorderly phenomenon, when consequently use next time, can't twisted rope be pulled out smoothly again.

Be illustrated in figure 1 as the side part cross-sectional schematic of existing winch, winch 1 has a pedestal 11, a spool 12 is pivoted on pedestal 11, coiling one twisted rope 13 on it, twisted rope 13 can be drawn out by the front end (Fig. 1 is right-hand) of pedestal 11, a spool 12 and a gear cluster 14 are connected with simultaneously, be used for slowing down and improving torsion, when drive power source gear cluster 14, but interlock spool 12 furls twisted rope 13, when discharging twisted rope 13, then must be with the manpower drawing, and existing winch 1 is when furling twisted rope 13, must keep twisted rope 13 has and certain furl tension force and twisted rope 13 tightly could be wound in spool 12, if do not keep certain tension force that furls, then twisted rope 13 is understood loose being wound on mussily on the spool 12, during tension next time twisted rope 13, twisted rope 13 on the spool 12 is understood some and is tightened, some is still kept loose, and produce from the phenomenon of tiing up, when pulling out twisted rope 13 once more, this can make twisted rope 13 continue to be drawn out from tiing up phenomenon again, therefore winch 1 promptly can't be used smoothly, and this thing happens in order to avoid for existing winch 1, when furling tension-free twisted rope 13, must there be a people to hold twisted rope 13 all the time, to keep certain tension force that furls, therefore, there is the shortcoming that furls twisted rope 13 inconvenience in the use in existing winch 1.

Secondly, except the above-mentioned twisted rope 13 that furls under tension-free state may cause twisted rope 13 loose from tiing up the phenomenon, have under the situation of tension force in twisted rope 13 loadings, the loose phenomenon of twisted rope 13 still may take place, as shown in Figure 2, the vehicle 2 that glides of twisted rope 13 drawings for example, when vehicle 2 is pulled to eminence, vehicle 2 moves forward automatically because of ground is recessed most probably, and its speed that moves furls the speed of twisted rope 13 faster than spool 12, causes twisted rope to be in tension-free state in 13 a period of times, loose phenomenon promptly can take place in the twisted rope 13 on the spool 12 at this moment, therefore, existing winch 1 is as long as under twisted rope 13 tension-free states, and twisted rope 13 promptly can furl loose in a jumble.

The purpose of this utility model has guiding and keeps the winch that twisted rope furls tension force when just being a kind of furling is provided.
