The invention relates to an overhead ground wire lifter which comprises a hoop, a transverse beam, suspension points and a fixed pulley. The transverse beam is arranged on the hoop, the suspension points are arranged on the transverse beam, the fixed pulley can be suspended on the suspension points, the rear end of the transverse beam is movably connected with the hoop, the middle of the transverse beam is lapped on the hoop, the front of the transverse beam extends out of the hoop, the suspension points are arranged on an extending portion of the transverse beam, one of the suspension points is connected with the fixed pulley, and a safety rope is wound on the fixed pulley. The overhead ground wire lifter has the advantages that the overhead ground wire lifter is simple in structure, can stably sleeve the top of an electric pole, is provided with the anti-drop safety rope and can be prevented from falling to injure ground personnel by means of crashing; the safety rope also can be used for lifting to-be-erected ground wires; overhead operation can be carried out on the ground wires at optional altitudes in service procedures; the overhead ground wire lifter is easy and convenient to operate, the quantity of overhead operation personnel can be effectively reduced, sufficient operation spaces can be reserved for the operation personnel, and accordingly a safety coefficient of overhead operation can be increased.
Description
Technical field
The present invention relates to a kind of lifting device, particularly relating to a kind of overhead-groundwire lifter used when setting up ground wire.
Background technology
Mostly transmission line is to be erected at outdoor, and when being subject to wind, circuit can swing with the wind, is in microseism for a long time and swings state, easily causes the disconnected strand of overhead grounding wire in suspension clamp, therefore needs regularly to overhaul place line outage.When overhauling in the past, operating personnel be by line to be renewed pickaback to electric pole top, carry out stringing subsequently.Owing to needing multi-user collaborative operation when changing high-altitude circuit, and head of the mast space is less, and operating space is also little, therefore old-fashioned thread-changing mode has great danger to operating personnel.
For solving high-altitude stringing problem, there is some lifting devices in prior art and adopting high-altitude that the mode of pulley and bracing wire is set, treating the new line of frame by the lifting of bracing wire and promote.Its only applicable anchor ear that is connected with electric pole is socketed, but the installing of anchor ear needs to position its fastening bolt, and also need after being suitable for dismantle anchor ear, comparatively loaded down with trivial details, especially when work high above the ground, it is more inconvenient to set up, not easy to operate.And if anchor ear bolt looseness when installing, then the anchor ear very easily downward landing of para-electric bar, thus accidents caused.
Summary of the invention
The object of the invention is to propose one and can be located at the head of the mast by stabilizing bracket, be convenient to installing, the overhead-groundwire lifter treating frame ground wire can be promoted rapidly.
The object of the present invention is achieved like this: overhead-groundwire lifter its be by anchor ear, be installed in the crossbeam on anchor ear, and the hitch point be arranged on crossbeam, with the fixed pulley composition be articulated on hitch point, described crossbeam rear end is connected with anchor ear is active, and middle part is taken on anchor ear, anchor ear is stretched out in front portion, crossbeam extension is provided with hitch point, and wherein a hitch point is connected with fixed pulley, and fixed pulley is wound with safety rope.
Owing to implementing technique scheme, structure of the present invention is simple, and what it can be firm is placed on electric pole top, and arranges Anti-fall safety rope, and preventing from dropping injures ground staff by a crashing object.Safety rope treats frame ground wire for promoting simultaneously.In use can carry out earth wire rack idle job in arbitrary height.The application is easy and simple to handle, effectively can reduce work high above the ground personnel number, for operating personnel reserves enough working spaces, improves the coefficient of safety of work high above the ground.
Accompanying drawing illustrates: concrete structure of the present invention is provided by following drawings and Examples:
Fig. 1 is overhead-groundwire lifter structural representation.
Legend: 1, right supported plate, 2, left supported plate, 3, reserved hanging ring, 4, positioning rope, 5, front supporting plate, 6, rear carrier plate, 7, safety rope, 8, fixed pulley, 9, hanging ring, 10, supporting bracket, 11, crossbeam, 12, anchor ear.
Embodiment:
The present invention by the restriction of following embodiment, can not determine concrete execution mode according to technical scheme of the present invention and actual conditions.
Embodiment: as shown in Figure 1, overhead-groundwire lifter its be by anchor ear 12, is installed in the crossbeam 11 on anchor ear 12, and is arranged on the hitch point on crossbeam 11, and the fixed pulley 8 be articulated on hitch point forms.Described crossbeam 11 rear end is connected with anchor ear 12 is active, and middle part is taken on anchor ear 12, and anchor ear 12 is stretched out in front portion, and crossbeam 11 extension is provided with hitch point.Wherein a hitch point is connected with fixed pulley 8, and fixed pulley 8 is wound with safety rope 7.Crossbeam 11 lower end of anchor ear 12 lap-joint is provided with supporting bracket 10, and when anchor ear 12 closes, supporting bracket 10 is connected in anchor ear 12 excircle place.
Described hitch point is separately positioned on crossbeam 11 foremost, the left and right sides at front end and middle part.Corresponding described four hitch points comprise front, rear, left and right support plate 5,6,2,1, and the reserved hanging ring 3 that forward and backward support plate 5,6 upper end is fixing, and the hanging ring 9 that left and right support plate 2,1 upper end is fixing.
Crossbeam 11 between described forward and backward support plate 5,6 is have positioning rope 4, and positioning rope 4 is for the colligation overhead ground wire when work high above the ground.Also overhead ground wire directly can be carried on a shoulder pole between forward and backward support plate 5,6 or left and right support plate 2,1.
For preventing the unexpected crossbeam 11 in high-altitude from turning upside down, with anchor ear 12 lap-joint, can locking device be set at crossbeam 11, such as: at crossbeam 11, place has screw, hold-doun nut on anchor ear 12 inwall or outer wall, by spinning of bolt and nut, crossbeam 11 and anchor ear 12 can be completely fixed.
During use, roughly regulate anchor ear 12 circumference on ground according to electric pole circumference, operating personnel carries the application to electric pole upper end, subsequently anchor ear 12 is placed on the head of the mast, until crossbeam 11 and electric pole upper end contact, anchor ear 12 is located.Subsequently fixed pulley 8 is suspended on any hitch point on crossbeam 11, hung by overhead ground wire by positioning rope 4, now positioning rope 4 is by downward pulling force, then crossbeam 11 is simultaneously by downward pulling force, because anchor ear 12 is socketed in electric pole place, therefore the application's entirety not easily gets loose by electric pole under stress.Check the whether disconnected stock of overhead ground wire in suspension clamp subsequently, operating personnel overhauls overhead ground wire according to actual conditions.Safety rope 7 not only prevents the application from being dropped by high-altitude, also can treat that the new line of frame uses as conveying simultaneously.To treat that the new line of frame is tied on safety rope 7, ground staff, by pulling safety rope 7, will treat that the new line of frame is pulled to high-altitude gradually.After being pulled to assigned address, bundled location, to treat that it is used by work high above the ground personnel by positioning rope 4.
Above technical characteristic constitutes most preferred embodiment of the present invention, and it has stronger adaptability and best implementation result, can increase and decrease inessential technical characteristic according to actual needs, meet the needs of different situations.
