Detailed description of the invention
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 side, pivot shaft 3 is installed pulley 8, pulley 8 is equipped with crank 1, the lower end of coaster support 9 is provided with insurance gib head 10, pulley 8 is offered through hole 16, arrange two straight-bars 17 in through hole 16, 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 diameter, keeps compact.The two ends of each straight-bar 17 are all outside at through hole 16, 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, can coordinate fast clamp from through hole 16 lower end after stretching out with the edge of through hole 16.The top of straight-bar 17 arranges wedge 14, the point upward of wedge 14, the top of two straight-bars 17 connects cylindricality block 19, and arrange blind hole 15 bottom cylindricality block 19, straight-bar 17 inserts in blind hole 15, the hole wall of blind hole 15 is offered wedge hole 22, wedge 14 is through wedge hole 22, and cylindricality block 19 top connects stay cord 5, when wedge 14 is pushed wedge hole 22, from up to down slide and press, namely change the position of holding cylindricality block 19 and just can complete coordinating between straight-bar 17 with pulley 8.The line of centers specular of the sphenocephaly 18 on two straight-bars 17, wedge 14 1 cylindricality fast 19, arranges spring leaf 13 between two straight-bars 17, the power that spring leaf 13 gives straight-bar 17 1 outside all the time.Adopt between stay cord 5 with pulley 8 and be fixedly connected with, avoid the phenomenon that stay cord 5 and pulley skid, equipment rises steadily, stay cord 5 uniform force, ensures the safety that stay cord 5 uses, transportation safety and stability; Different according to the equipment of transport, be convenient for changing different stay cords, easy disassembly between stay cord 5 and pulley 8, increase work efficiency.
Working process is: first will insure gib head, and 10 hang on fixed object, is then inserted in the through hole 16 of pulley 8 by the end of stay cord 5, and the other end of stay cord hangs weight, and weight can be mentioned by shake crank 1.When stay cord 5 and pulley 8 are fixed, two straight-bars 17 are inserted in through hole 16, sphenocephaly 18 through after through hole 16 under the effect of spring leaf 13, separately, sphenocephaly 18 is stuck in the edge of through hole 16 to two straight-bars 18, plays fixation; When with when changing stay cord, inwardly press from up to down and pinch wedge 14, two straight-bars 17 come closer, and sphenocephaly 18 is separated with the edge of through hole 16, thus are extracted out by straight-bar 17, realize the object of dismounting, then are connected by new stay cord.
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 block 19 periphery arranges pivoted housing 12, pivoted housing 12 inwall arranges negative thread, and cylindricality block 19 periphery arranges outside thread, and negative thread and outside thread match.By rotating pivoted housing 12, pivoted housing 12 moves downward, and is inwardly extruded by wedge 14, thus is moved inward by two straight-bars 17, thus reaches the object of fast power-saving dismounting.
In order to keep the horizontal motion of straight-bar 17, arrange horizontal slide rail 21 bottom described blind hole 15, straight-bar 17 top arranges slide block 20, and slide block 20 and slide rail 21 match.Straight-bar 17 is parallel motion, reduces distance when straight-bar 17 closes up, and the distance of two sphenocephalies 18 is nearer, and the maximum width of two sphenocephalies 18 is less, is convenient to, in unloading process, the sphenocephaly 18 of straight-bar 17 end is passed through hole 16.
The conveniently winding of stay cord 5, described cylindricality block 19 periphery arranges vertical wire casing 11, the first lap that stay cord 5 is wound around can coordinate with wire casing 11, stay cord 5 can through the centre of two straight-bars 17, prevent two straight-bars 17 from closing up, avoid use procedure medium pulling rope 5 to be separated with pulley 8, thus improve the safety used in process of the present invention.
Described pulley bracket 9 is provided with fixed point lock pin 7, 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 inserted in the hole of pulley 8 side by fixed point lock pin 7.
In order to not allow coaster rock, install assistant support 2 between described crank 1 and pulley 8, crank 1 is arranged on one end of assistant support 2, and the other end of assistant support 2 installs balance block 4, and fixed handle 6 is installed on the top of coaster support 9.One of operator is hand to shake 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 technology contents of the not detailed description of the utility model is known technology.
