The specific embodiment
Substation's hand-operated tackle, as shown in Figure 1, comprises coaster support 9, the middle part fixed pedestal axle 3 of coaster support 9 one sides, pulley 8 is installed on pivot shaft 3, crank 1 is housed on pulley 8, the lower end of coaster support 9 is provided with insurance gib head 10, on pulley 8, offer through hole 16, through hole 16 is interior arranges two straight-bars 17, and application force is evenly distributed on two straight-bars 17, and two straight-bars 17 interact, the width of the straight-bar 17 after closing up is corresponding with through hole 16 internal diameters, keeps compact.The two ends of each straight-bar 17 are all in through hole 16 outsides, the lower end of straight-bar 17 arranges sphenocephaly 18, the pointed end of sphenocephaly 18, sphenocephaly 18 conveniently has direction as shown to enter in through hole 16 from top to bottom, from stretch out through hole 16 lower ends, can coordinate clamping with the edge of through hole 16 fast.The top of straight-bar 17 arranges wedge 14, the point upward of wedge 14, the top of two straight-bars 17 connects cylindricality piece 19, and cylindricality piece 19 bottoms arrange blind hole 15, and straight-bar 17 inserts in blind hole 15, on the hole wall of blind hole 15, offer wedge hole 22, wedge 14 is through wedge hole 22, and cylindricality piece 19 tops connect stay cord 5, when wedge 14 is pushed to wedge hole 22, from up to down slide and press, the position that changes assurance cylindricality piece 19 just can complete coordinating between straight-bar 17 and pulley 8.The line of centers mirror image of the sphenocephaly 18 on two straight-bars 17, wedge 14 1 cylindricalitys fast 19 is symmetrical, between two straight-bars 17, spring leaf 13 is set, and spring leaf 13 is given 17 1 outside power of straight-bar all the time.Between stay cord 5 and pulley 8, adopt and be fixedly connected with, the phenomenon of avoiding stay cord 5 and pulley to skid, equipment rises steadily, and stay cord 5 is stressed evenly, guarantees the safety that stay cord 5 is used, transportation safety and stability; Different according to the equipment of transportation, be convenient for changing different stay cords, easy disassembly between stay cord 5 and pulley 8, increases work efficiency.
Working process is: first will insure gib head, 10 hang on fixed object, then the end of stay cord 5 is inserted in the through hole 16 of pulley 8, and the other end of stay cord hangs weight, shakes crank 1 and weight can be mentioned.Stay cord 5 is with pulley 8 fixedly time, and two straight-bars 17 are inserted in through hole 16, sphenocephaly 18 through after through hole 16 under the effect of spring leaf 13, two straight-bars 18 separate, sphenocephaly 18 is stuck in the edge of through hole 16, plays fixation; When changing stay cord, to pinch 14, two straight-bars 17 of wedge in inwardly pressing from up to down and come closer, sphenocephaly 18 is separated with the edge of through hole 16, thereby straight-bar 17 is extracted out, realizes the object of dismounting, newer stay cord is connected.
When stay cord is too tightened, sphenocephaly 18 coordinates too tension with the edge of through hole 16, in order to reach the object of dismounting, described cylindricality piece 19 peripheries arrange pivoted housing 12, pivoted housing 12 inwalls arrange negative thread, and cylindricality piece 19 peripheries arrange outside thread, and negative thread and outside thread match.By rotating pivoted housing 12, pivoted housing 12 moves downward, and wedge 14 is inwardly pushed, thereby two straight-bars 17 are moved inward, thereby reach the object that fast power-saving is dismantled.
In order to keep the horizontal motion of straight-bar 17, described blind hole 15 bottoms arrange horizontal slide rail 21, and straight-bar 17 tops arrange slide block 20, and slide block 20 and slide rail 21 match.Straight-bar 17 is parallel motion, the distance when reducing straight-bar 17 and closing up, and the distance of two sphenocephalies 18 is nearer, and the maximum width of two sphenocephalies 18 is less, is convenient in unloading process the sphenocephaly of straight-bar 17 ends 18 through through hole 16.
In order to facilitate the winding of stay cord 5, described cylindricality piece 19 peripheries arrange vertical wire casing 11, the first lap that stay cord 5 is wound around can coordinate with wire casing 11, stay cord 5 can be through the centre of two straight-bars 17, prevent that two straight-bars 17 from closing up, avoid use procedure medium pulling rope 5 separated with pulley 8, thereby improve the safety of using in process of the present invention.
Fixed point lock pin 7 is installed on described pulley bracket 9, and fixed point lock pin 7 is arranged on the end of the wheel body of pulley 8, if allow weight stop in certain position, as long as fixed point lock pin 7 is inserted in the hole of pulley 8 sides.
In order not allow coaster rock, between described crank 1 and pulley 8, assistant support 2 is installed, crank 1 is arranged on one end of assistant support 2, and the other end of assistant support 2 is installed balance block 4, and fixed handle 6 is installed on the top of coaster support 9.Operator's hand shaking 1, another hand steered fixed handle 6, crank balance block 4 allows crank 1 keep a state of equilibrium all the time.
The technical solution of the utility model is not restricted in the scope of embodiment described in the utility model.The utility model not technology contents of detailed description is known technology.
