Description
Technical field
The utility model relates to a kind of jacking application specific standard joint hoisting bracket for the electric power pole, belongs to the lifting appliance technical field.
Background technology
The electric power pole is the Special Hoisting Equipment of electric power tower group tower, and the jacking supernumerary segment operation of electric power pole often all will use mobile crane, and mobile crane hangs standard knot on the introduction platform of electric power pole jacking supernumerary segment, carries out the work of jacking supernumerary segment then.
Along with the great development of China's economy, more and more to the demand of electric power, but primary energy distributes and the productivity development level is very unbalanced.2/3rds energy resources mainly are distributed in western part and the north, and 2/3rds energy demand mainly concentrates on the developed area, east, energy resources and productivity development are reverse distribution, so need to build a large amount of electrical networks, realize trans-regional, stride the basin two things diametrically opposed to each other, electric energy is transported to area, the central and east from western and the north, the promotion China's economic is faster, better, stronger development.But Chinese hypsography is very big, and Xi Gaodong is low, is three grades of stepped distributions, and the Northwest is many, and lofty mountains and steep hills, the hydroelectric resources that there is richly stored with, many Plains, southeast fertile field.Even the milder southeast of relative relief is along with the aortic construction of electrical network, transmission line of electricity much will pass barren hill, a lot of electric power towers are built the extremely bad place of transportation condition in, do not have condition transportation large lifting equipment at all, can only lean on the most original pickaback portablely, can not use this large lifting equipment of mobile crane that standard knot is hung on the introduction platform of electric power pole jacking supernumerary segment.
The utility model content
Technical problem to be solved in the utility model be overcome deficiency of the prior art and provide a kind of simple in structure detachable, safe and reliable, on-the-spot install efficiently light, improve efficiency of construction, reduce the jacking application specific standard joint hoisting bracket of construction cost.
The technical scheme in the invention for solving the above technical problem is: this jacking application specific standard joint hoisting bracket comprises fixedly anchor ear, two pull bars and two girders, described fixedly anchor ear is installed in the jacking stock and introduces on two main chords of face, two fixedly anchor ears are installed on the every main chord, one end of described two pull bars respectively with two main chords on be positioned at top two fixedly anchor ear be connected, an end of described two girders is positioned at following fixedly anchor ear and is connected respectively with on two main chords; The other end of described two girders interconnects with bolt; The other end of described two pull bars is connected with the end that interconnects of two girders respectively; Described fixedly anchor ear, two pull bars and two girders form the triangular truss structure.Pull bar plays the stressed effect of sharing, and standard knot can be lifted by crane on the introduction platform of electric power pole jacking supernumerary segment, carries out the work of jacking supernumerary segment then.
Be provided with adjusting screw(rod) in the pull bar described in the utility model.Can adjust pull bar length within the specific limits, eliminate and make and alignment error.
The end that interconnects of two girders described in the utility model is provided with otic placode.Otic placode is used for simple and easy little heavy-duty hoisting equipment is installed, on cucurbit or assembly pulley.
Fixedly anchor ear described in the utility model, two pull bars and two girders are detachable single chip architecture.
The utlity model has following advantage: the utility model has adopted a kind of structure of detachable form, has reduced transport space and transportation single-piece weight, and on-the-spot installation is efficiently light; Contemporary for a mobile crane that needs on the place to reside, significantly reduce construction cost, and improved efficient; Do not need large lifting equipment standard knot can be hung yet and deliver on the introduction platform.

The specific embodiment
Be described in further detail below in conjunction with the utility model of embodiment, following examples are to explanation of the present utility model and the utility model is not limited to following examples.
Embodiment: shown in Fig. 1 to 4, the utility model comprises fixedly anchor ear 1, pull bar 2, girder 3, adjusting screw(rod) 4 and otic placode 5.One end of two girders 3 interconnected with bolt form the triangle horizontal plane, the other end is connected with fixing anchor ear 1 respectively; One end of two pull bars 2 is connected with the end that interconnects of bearing pin and two girders 3, and the other end is connected with fixing anchor ear 1 respectively, forms stable triangular truss structure.Fixing anchor ear 1 is fixed on the jacking stock introduces on the main chord of face, come a grade spacing of opening that adapts to various stocks by the precession length of regulating bolt 4.
In the work, fixedly anchor ear 1, pull bar 2, girder 3 and otic placode 5 are assembled into integral body on ground, the standard knot that the utility model is installed in the jacking stock is introduced proper height directly over the track height of a standard knot (approximately greater than), the precession length of adjusting screw(rod) 4, making fixedly, anchor ear 1 is connected firmly with the stock main chord; Simple and easy small-sized hanging device (cucurbit or pulley) is installed in the lifting hole(eyelet) place of the otic placode 5 on the girder 3; Fix the standard knot of wanting the jacking supernumerary segment with simple and easy mini-plant; By the electric power of manpower or small generator standard knot is sling then; Standard knot is put on the introduction platform of jacking stock, removes suspension hook; Just can carry out the jacking supernumerary segment then, increase the body of the tower of pole, increase lifting altitude.
In addition, need to prove, the specific embodiment described in this manual, its zero, the shape of parts, institute's title of being named etc. can be different.Allly conceive equivalence or the simple change that described structure, feature and principle are done according to the utility model patent, be included in the protection domain of the utility model patent.The utility model person of ordinary skill in the field can make various modifications or replenishes or adopt similar mode to substitute described specific embodiment; only otherwise depart from structure of the present utility model or surmount the defined scope of these claims, all should belong to protection domain of the present utility model.
