Abstract
The utility model discloses a labor-saving hand-operated pulley, and relates to pulley devices in construction process of live working. The pulley comprises a pulley support, a fixed handle is mounted at the upper end of one face of the pulley support, a support shaft is fixed on the upper middle portion of the other face of the pulley support, a sheave body mounted on the support shaft is equipped with a crank, a crank balance block is fixed at the lower end of the crank, a safety hook is mounted at the lower end of the pulley support, and a fixed-point locking pin is mounted on the pulley support. The pulley has the advantages of simple and safe operation, labor saving and reduction, and capability of retaining an article at optional position between two slides.
Description
Technical field
The utility model relates to the tackle rigging in the livewire work work progress, specifically is a kind of laborsaving hand-operated tackle.
Background technology
In line construction, there are a large amount of tool materials to come and go down and transmit from tower on the tower, the endless rope transmission of traditional method can only change direction, can not be laborsaving, labour intensity is very big.If want to allow object stop a position, then need the people to hold endless rope, wasted a large amount of labours.
Summary of the invention
At the deficiencies in the prior art, the utility model provides a kind of laborsaving hand-operated tackle, can easily object be mentioned, and at any time can be easily object be parked in any position between two slide rails.
The utility model is realized with following technical scheme: a kind of laborsaving hand-operated tackle, comprise a coaster support, the upper end of coaster support one side is equipped with fixed handle, a back shaft is fixed in the middle and upper part of another side, pulley body is housed on the back shaft, crank is housed on the pulley body, a crank balance weight is fixed in the lower end of crank, an insurance gib head is fixed in the lower end of coaster support, also comprises the fixed point lock pin that is installed on the coaster support.
The beneficial effects of the utility model are: safety simple to operate, and laborsaving, reduce the labour, can also be parked in optional position between two slide rails to object.
Description of drawings
The utility model is described in further detail to reach embodiment in conjunction with the accompanying drawings.
Fig. 1 is the utility model outside drawing;
Fig. 2 is the right view of pulley body 5.
Among the figure: 1, insurance gib head, 2, the coaster support, 3, the fixed point lock pin, 4, fixed handle, 5, pulley body, 6, the crank balance weight, 7, crank, 8, back shaft.
The specific embodiment
As shown in drawings, laborsaving hand-operated tackle, comprise a coaster support 2, the upper end of coaster support 2 one sides is equipped with fixed handle 4, and the middle and upper part of another side is equipped with back shaft 8, and pulley body 5 is housed on the back shaft 8, crank 7 is housed on the pulley body 5, a crank balance weight 6 is fixed in the lower end of crank 7, and the lower end of coaster support 2 is equipped with insurance gib head 1, and fixed point lock pin 3 also is housed on the coaster support 2.Crank 7 is equipped with nut at back shaft 8 near the position of crank 7 by on the lateral surface that is bolted to pulley body 5.
As shown in Figure 2,27 holes evenly distribute on pulley body 5 close coaster support 2 those sides, 3 of lock pins of fixed point are installed in and pulley body 5 sides topmost on the coaster support 2 of hole correspondence, the fixed point lock pin is inserted in the corresponding topmost hole, pulley body 5 sides, pulley body 5 can be pinned, this moment, weight then rested on aerial certain position.
The course of work is: at first will insure gib head 1 and hang on the fixed object, then the endless rope on the slide rail is twined a circle on pulley body 5, wherein on the endless rope of a side, weight is housed, the endless rope of this moment is tightened, shaking crank 7 can mention weight, if allow weight stop, as long as the lock pin 3 of will fixing a point inserts in the hole, the top of pulley body 5 sides in certain position.In order not allow coaster rock, operator's hand shaking 7, another hand steered fixed handle 4, crank balance weight 6 allows crank 7 keep a poised state all the time.
Contrast effect: in the livewire work construction, the lifting article only need a people even a hand just can mention laborsaving about 80%.
