Abstract
The utility model discloses a kind of small-sized hand and pull wire grip, it comprises major axis, cluster gear axle and integral type drive sprocket, cluster gear axle has a pair, the single piece that each cluster gear axle is made up of a plate gear and a minor axis gear, the single piece that described integral type drive sprocket is made up of a sprocket wheel and a final-stage gear, integral type drive sprocket is sleeved on major axis, the end tooth of major axis engages with the plate gear of a pair cluster gear axle, and this all engages with the final-stage gear of integral type drive sprocket the minor axis gear of cluster gear axle.After adopting technique scheme, major axis has end tooth, when external force drives major axis to rotate, end tooth is directly engaged with a pair cluster gear axle, drive integral type drive sprocket to rotate by the engagement of cluster gear axle, thus achieve stringing operation, embody the feature of whole drive mechanism compact, reduce the volume of loop chain wire grip, the hand meeting low tractive effort pulls the needs of wire grip small light.
Description
[technical field]
The utility model relates to a kind of small-sized hand and pulls wire grip, and supply lines, cable stringing are used, is applicable to 0.25 ~ 0.5 kilogram of tractive effort.
[background technology]
Hand is pulled wire grip and is widely used in the occasions such as national grid, warehouse, harbour, power station, logging headquarter, in tension operation, play good stringing effect.
At present, the hand of low tractive effort pulls wire grip ubiquity volume problem bigger than normal, carry to stringing work, high-altitude application brings very big inconvenience, the volume being mainly reflected in transmission mechanism is excessive, because drive sprocket and final-stage gear are split type, and every plate gear and minor axis gear are also Split type structures, the bottleneck that this transmission mechanism volume being restriction hand pulls wire grip cannot effectively reduce, the hand of low tractive effort pull wire grip due to volume excessive, correspondingly, make stringing work labour intensity large, bring certain impact to stringing operating efficiency.
[utility model content]
The technical problems to be solved in the utility model is the deficiency that exists for above-mentioned prior art and provides a kind of small-sized hand to pull wire grip.
It is as follows that the utility model solves the problems of the technologies described above adopted technical scheme:
A kind of small-sized hand pulls wire grip, comprise major axis, cluster gear axle and integral type drive sprocket, described cluster gear axle has a pair, the single piece that each cluster gear axle is made up of a plate gear and a minor axis gear, the single piece that described integral type drive sprocket is made up of a sprocket wheel and a final-stage gear, integral type drive sprocket is sleeved on major axis, the end tooth of major axis engages with the plate gear of a pair cluster gear axle, and this all engages with the final-stage gear of integral type drive sprocket the minor axis gear of cluster gear axle.
The advantage that the utility model compared with prior art has is:
Major axis has end tooth, when external force drives major axis to rotate, end tooth is directly engaged with a pair cluster gear axle, integral type drive sprocket is driven to rotate by the engagement of cluster gear axle, thus achieve stringing operation, embody the feature of whole drive mechanism compact, be conducive to the volume greatly reducing loop chain wire grip, the hand meeting low tractive effort pulls the needs of wire grip small light.
[accompanying drawing explanation]
Be described in further detail with regard to the utility model below in conjunction with accompanying drawing.
Fig. 1 is front view of the present utility model;
Fig. 2 is structural representation of the present utility model;
Fig. 3 is explosive view of the present utility model.
[embodiment]
Referring to shown in Fig. 1,2,3, is preferred embodiment of the present utility model.
A kind of small-sized hand pulls wire grip, comprise major axis 1, cluster gear axle 2 and integral type drive sprocket 3, described cluster gear axle 2 has a pair, the single piece that each cluster gear axle 2 is made up of a plate gear 21 and a minor axis gear 22, the single piece that described integral type drive sprocket 3 is made up of a sprocket wheel 31 and a final-stage gear 32, integral type drive sprocket 3 is sleeved on major axis 1, the end tooth 11 of major axis 1 engages with the plate gear 21 of a pair cluster gear axle 2, this all engages with the final-stage gear 32 of integral type drive sprocket 3 the minor axis gear 22 of cluster gear axle 2.
Adopt the hand of the technical program to pull wire grip, for 250 kilograms of rated drawbar pulls, body width is only 79.5mm, and body height is only 95mm, and the minimum hook spacing between upper and lower hook is then 220mm.
During utility model works, with handle drives assembly 4 for power, rotate clockwise handle drives assembly 4, commutation ratchet (sign) is impelled to move along the multiple thread Duan Shangxuan of major axis 1 by the commutation ratchet (not indicating in figure) of handle drives assembly 4, until commutation ratchet and outside friction disc 51, ratchet 6, inner attrition piece 52, brake seat 7 and major axis 1 are pressed into one, under frictional drive, make 81 promotion ratchet 6 one-directional rotation (detent 82 coordinates) of pawling, major axis 1 is driven to rotate with the rotation of ratchet 6, the plate gear 21 of end tooth 11 engaged transmission a pair cluster gear axle 2 of major axis 1, and make this to the final-stage gear 32 of the minor axis gear 22 engaged transmission integral type drive sprocket 3 of cluster gear axle 2, stringing chain 9 is driven to move to realize sprocket wheel 31, thus carry out tension electric wire, wireline operation, when rotating counterclockwise handle drives assembly 4, commutation ratchet and outside friction disc 51, ratchet 6, inner attrition piece 52, brake seat 7 produce relative displacement, clutch gap (0.5 ~ 1.0mm) is produced between commutation ratchet and outside friction disc 51, under the non-return effect of detent 82, limit ratchet 6 reverse, now braking is worked.
Handle drives assembly 4 is known features, and it is made up of commutation ratchet, commutation ratchet, ratchet bearing pin, ball, ball spring, handle and taper knob.
