Abstract
The utility model relates to a pulley guiding device of a bottle screw. The pulley guiding device of the bottle screw comprises a pulley frame, bearings, pulleys, pulley shafts, a guide rod, and other parts. The sliding friction between the guide rod and a sliding shaft is converted to rolling friction between the pulleys and the guide rod, lifting and rotary steering are achieved through the pulleys, so the problem of concentricity of the guide rod and the pulleys is resolved, friction is reduced, and service life is prolonged.
Description
Technical field
The utility model relates to a kind of pulley guide piece of bottle screw, belongs to the weight-hauling equipment technical field.
Technical background
In the prior art, the elevator guide rod all is to realize, turn round through sliding shaft sleeve, and sliding shaft sleeve and guide rod free-running fit if the gap is little, can produce stuck problem in lifting process.The gap is big, can't guarantee the right alignment of guide rod and sliding shaft sleeve, and the diametral load that is produced, moment of flexure can make the screw mandrel friction increase, and reduce service life.
Disclose a kind of leading sheave mechanism among the CN201781317U, be used for the on/off switch slide block of dual power supply automatic switching device, this leading sheave mechanism comprises push rod, slide block, one group of axis of guide, pulley, base plate.Pulley is installed in the bottom of slide block through rivet; One group of axis of guide is riveted on the floor, has two waist holes on the slide block, and slide block is installed on one group of axis of guide through circlip; One group of axis of guide lays respectively in two waist holes, and push rod promotes slide block along one group of axis of guide longitudinal movement.This device can reduce largely because the resistance that gap and self torsional deflection of member are produced between member and to the destruction of part.Need the axis of guide, the integral structure relative complex of following more.Though the effect that reduces resistance is arranged, only be directed to small-sized mechanism and be suitable for, be prone under the heavily loaded situation produce the conquassation phenomenon, be not suitable for the hoisting operation in the machinery production.
Summary of the invention
In order to solve the problem that exists in the above-mentioned known technology; The purpose of the utility model provides a kind of pulley guide piece of bottle screw; Convert the cliding friction between guide rod and the sliding shaft sleeve between pulley and the guide rod friction of rolling, realize up-down, rotary steering, solved the right alignment problem of guide rod and pulley through pulley; Reduce friction, prolonged service life.
The utility model realizes that by following technical scheme it comprises pulley yoke 1, bearing 2, pulley 3, sheave shaft 4, guide rod 5.Two pairs of pulleys 3 are installed between the parallel pulley yoke of mutual correspondence 1 perpendicular to pulley yoke 1 through sheave shaft 4; Constitute the pulley guide piece, pulley guide piece contact gripping is installed on the guide rod 5, is installed on the sheave shaft 4 after pulley 3 two ends and pair of bearings 2 interference fit; The external lifting cantilever that is connected after erecting bed 6 is connected through bolt and pulley yoke 1; Described pulley yoke 1 is that two blocks of steel plates that are equipped with axis hole constitute, and two block plates are parallel relatively, and four axis hole positions are corresponding.
The utility model is a kind of jacking system of realizing up-down, rotary steering through pulley.Its compact conformation, easy to use is widely used.
Compare the advantage that has with known elevator guide devices:
1) realizes up-down, rotary steering with pulley, convert traditional cliding friction into friction of rolling, reduce effectively
Equipment wearing and tearing in the course of the work, improved service life, avoided the stuck phenomenon in the lifting process;
2) pulley guiding, rotation have reduced in the lifting process dynamic load, impact load influence to guide rod;
3) pulley and guide rod contact gripping are installed, reduced since between member gap and self torsional deflection of member produce
Resistance and to the destruction of part.
Description of drawings
Fig. 1 is the composition structural representation of the utility model, and 1 is pulley yoke among the figure, and 3 is pulley, and 4 is sheave shaft, and 5 is guide rod, and 6 is erecting bed.
Fig. 2 is the birds-eye view of Fig. 1, and 2 is bearing among the figure.
The specific embodiment
Embodiment: structure as shown in Figure 1, it comprises pulley yoke 1, bearing 2, pulley 3, sheave shaft 4, guide rod 5.Two pairs of pulleys 3 are installed between the parallel pulley yoke of mutual correspondence 1 perpendicular to pulley yoke 1 through sheave shaft 4; Constitute the pulley guide piece, pulley guide piece contact gripping is installed on the guide rod 5, is installed on the sheave shaft 4 after pulley 3 two ends and pair of bearings 2 interference fit; The external lifting cantilever that is connected after erecting bed 6 is connected through bolt and pulley yoke 1; Described pulley yoke 1 is that two blocks of steel plates that are equipped with axis hole constitute, and two block plates are parallel relatively, and four axis hole positions are corresponding.
The utility model is a kind of jacking system of realizing up-down, rotary steering through pulley.Its compact conformation, easy to use is widely used.
