Background technology
Under the prerequisite that Guo Wang company extremely payes attention to trouble free service, the operational procedure of a line operation employee has enough ensured the personal safety of employee, but has the fail safe of the instrument on some bases to need to improve.The main still rope of instrument that the bar of existing shop floor worker operation lifts, although also designed, designed improves traditional lift instrument, as crotch in the design of one, rope, some article (as electric energy meter) just no longer need side to prick like this, but need manually to lift, after operating personnel steps on bar, then rope is put down, required article bolt is well lifted afterwards.Alone rope lift, there is certain potential safety hazard, when carrying out operation on band electric pole, the scope of activities of arm still can not narrow down to minimum, easily touches electric wire, there is potential safety hazard.
Summary of the invention
Technical problem to be solved in the utility model is the defect existed for prior art, provides operation Portable carrying pull tool on a kind of bar, eliminates the potential safety hazard of operation on operating personnel's bar.
For solving this technical problem, the utility model provides operation Portable carrying pull tool on a kind of bar, comprise hook, rope and reel, one end coupling hook of described rope, the other end is connected to reel, described reel comprises housing, winding device and locking device, described winding device and locking device are arranged in housing, the back side of described housing is provided with belt clip, its front is provided with collapsible crank, described folding crank is connected with winding device, the folding crank of shake can drive winding device to put rope or rope closing, one end lockable rope that described locking device is arranged on winding device at an arbitrary position and prevent reversing.
Described winding device comprises power transmission shaft and winding wheel, and described transmission shafts, to offering interior chamfered groove, coordinates with folding crank grafting, is screwed; Described winding wheel is fixed on power transmission shaft, and one end of rope is fixed on winding wheel; Described power transmission shaft and housing joint portion are equipped with spring shim and are limited power transmission shaft and go out; Described locking device is arranged on one end of power transmission shaft.
Described locking device comprises spring, cam and lug, and spring is arranged on housing bottom and is provided with in circular groove, and the both ends level of spring curves inwardly and points to the center of circle; Described cam is provided with open slot, is fixed on power transmission shaft and is connected with winding wheel, lug is provided with outside winding wheel, lug is placed in the open slot of cam vertically, the width of open slot and the horizontal curvature adaptation in both ends of the spring portion, the horizontal curvature of two of spring ends is limited in its gap by the open slot cooperation of lug and cam.
Beneficial effect: the utility model is compared with existing design, the scope of activities of operating personnel's arm on bar during lift is narrowed down to minimum, reducing security incident odds, ensured personal safety, also ensureing that lifted article are from colliding with to the full extent simultaneously.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1 hook, 2 ropes, 3 reels, 4 folding crank, 5 power transmission shafts, 6 winding wheels, 7 spring shims, 8 screws, 9 springs, 10 cams.
Embodiment
Below in conjunction with drawings and Examples, the utility model is specifically described.
Figure 1 shows that structural representation of the present utility model.
The utility model comprises hook 1, rope 2 and reel 3, one end coupling hook 1 of described rope 2, and the article that can tangle do not need the artificial manual side that carries out to prick again, and raise labour efficiency; The other end is connected to reel 3, can carry out hand winding easily smoothly, reduce the scope of activities of arm.
Described reel 3 comprises housing 1, winding device and locking device, and described winding device and locking device are arranged in housing 1, and the back side of described housing 1 is provided with belt clip, and its front is provided with collapsible crank 4.
Described folding crank 4 is connected with winding device, and the folding crank 4 of shake can drive winding device to put rope or rope closing.
One end lockable rope 2 that described locking device is arranged on winding device at an arbitrary position and prevent reversing, adds fail safe more.
Described winding device comprises power transmission shaft 5 and winding wheel 6, and described power transmission shaft 5 axially offers interior chamfered groove, coordinates with the grafting of folding crank 4, is fixed by screw 8.
Described winding wheel 6 is fixed on power transmission shaft 5, and one end of rope 2 is fixed on winding wheel 6.
Described power transmission shaft 5 and housing 1 joint portion are equipped with spring shim 7 and are limited power transmission shaft 5 and go out, and also directly can be connected with housing 1 inwall by the foreign steamer of stay cord winding wheel 6.
Described locking device is arranged on one end of power transmission shaft 5.
Described locking device comprises spring 9, cam 10 and lug, spring 9 is arranged in the circular groove that to be provided with bottom housing 1 and to offer along power transmission shaft 5 radial direction, the both ends level of spring 9 curves inwardly and points to the center of circle, be loaded into after in groove at spring 9, the horizontal curvature of two ends forms a 30-60 ° of angle.
The bottom of described cam 10, with convex edge, coordinates with the bottom of housing 1 and is positioned in groove by spring 3.
Open slot is axially offered in the neighboring of described cam 10, and the width of open slot coordinates with the horizontal curvature loading groove inner spring 9 both ends.
Described cam 10 to be fixed on power transmission shaft 5 and to be connected with winding wheel 6.
Be provided with lug outside described winding wheel 6, lug is placed in the open slot of cam 10 vertically, and the horizontal curvature of two of spring 9 ends is limited in its gap by the open slot cooperation of lug and cam 10.
When needs promote, hand folding crank 4 rotates clockwise, and the horizontal curvature driving the lug on stay cord winding wheel 6 to promote spring 9 inwardly shrinks, and alleviates the friction between spring 9 and groove; After article are risen to certain position, due to Action of Gravity Field, power transmission shaft 5 produces opposition, the move horizontal curvature of spring 9 of lug reverse push expands outwardly, thus the frictional force added between spring 9 and groove, realize stay cord to be locked on certain position thus.
The utility model is compared with existing design, operating personnel on bar when will lift, especially the scope of activities of live line working personnel arm narrows down to minimum, scope of activities is less relatively safer, reduce security incident odds, ensureing personal safety, also having ensured that lifted article are from colliding with to the full extent simultaneously.
The above-mentioned embodiment of the utility model, just illustrates, is not only, and all changes within the scope of the utility model or in equivalent scope of the present utility model are all surrounded by the utility model.
