Background technology
Power department often can run into operation on bar in maintenance repair and handling labor, and weight, large equipment and the objects such as voltage transformer, circuit breaker are installed, and due to environments such as being subject to periphery road conditions, limits, and crane cannot be reached the spot.So it is very inconvenient that equipment is transported to eminence, mostly is now to install aloft fixed pulley, with rope, walks around fixed pulley, is assembled into easy lifting appliance, and this kind of mode comparatively required great effort, and careless slightly, and equipment will drop, and causes personnel and property damage.Even if sometimes there is crane, but part circuit is in farmland, and crane enters the crops that peasant can be damaged in camp site, to peasant, causes damage.
Summary of the invention
The object of the invention is to propose a kind of laborsaving, efficient, quick for installation, portable bar hand-jack.
The object of the present invention is achieved like this: with hand-jack, it comprises two crossbeams to bar, on two crossbeams, is provided with strut bar, and strut bar lower end is connected with anchor ear, at two crossbeam front ends, is provided with lappet, between two lappets, is provided with dead axle, is socketed capstan winch on dead axle.
Owing to implementing technique scheme, the present invention is simple in structure, and it can be fixed on electric pole fast; it utilizes capstan winch to reduce lifting weight; can be quick, stable equipment is winched to driving surface, solved the difficult problem that altitude plant is difficult for lifting, protected again the safety of lifting personnel and equipment.
Accompanying drawing explanation: concrete structure of the present invention is provided by following drawings and Examples:
Fig. 1 is bar hand-jack structural representation.
Legend: 1, crossbeam, 2, position-limited lever, 3, limiting stopper, 4, anchor ear, 5, strut bar, 6, lappet, 7, capstan winch.
The specific embodiment: the present invention is not subject to the restriction of following embodiment, can determine concrete embodiment according to technical scheme of the present invention and actual conditions.
Embodiment: as shown in Figure 1, bar comprises two crossbeams 1 with hand-jack, is provided with strut bar 5 on two crossbeams 1, and strut bar 5 lower ends are connected with anchor ear 4.At two crossbeam 1 front ends, be provided with between lappet 6, two lappets 6 and be provided with dead axle, on dead axle, be socketed capstan winch 7.At two crossbeam 1 rear portion opposite positions, being provided with inside face is that limiting stopper 3, two limiting stopper 3 front and rears of circular arc are provided with the position-limited lever 2 that connects two crossbeams 1, and position-limited lever 2 is located by jam nut.Two crossbeams 1 can parallelly be laid, and also can be front wide and rear narrow splayed and lay.At two crossbeam 1 middle parts, offer corresponding through hole, can pass through to regulate position-limited lever 2 in the position of different through holes and the fastening degree of jam nut, thereby regulate the opening angle of two crossbeams 1.
During use, anchor ear 4 is placed on electric pole, electric pole is snapped in limiting stopper 3 simultaneously.After locking anchor ear 4, then by position-limited lever 2 location.Pulley is installed in head of mast, and the steel rope of capstan winch 7 rises up into pulley, needs the equipment steel rope fixation of installation, and the crank on rotation capstan winch 7 can be realized the handling of equipment.
Above technical characterictic has formed most preferred embodiment of the present invention, and it has stronger comformability and best implementation result, can increase and decrease according to actual needs inessential technical characterictic, meets the needs of different situations.
