Description
Technical field
The present invention relates to a kind of constructional engineering machinery, especially relate to a kind of building ground tower crane.
Background technology
Tower crane is called for short tower machine, also known as tower crane, originates from West Europe.It is exactly the rotary crane that swing arm is contained in towering tower body top.Tower crane working space is large, is mainly used in the installation of vertical and horizontal feed and the building element of material in housing construction.Be made up of metal construction, operating mechanism and electric system three part.Metal construction comprises tower body, swing arm and base etc.Operating mechanism hoists, luffing, revolution and walking four part.Electric system comprises electrical motor, controller, electric power distribution cabinet, connection line, signal and illumination equipment etc.Along with the progress of engineering technology, the floor of present building is more and more higher, make required tower crane also more and more higher, but too high tower crane has the problem of poor stability, especially at southeastern coast During Typhoon, often there is tower crane and hung in typhoon sky the event created greater casualties.In addition, tower crane all needs to install clump weight, and clump weight is all hang on tower crane with other loop wheel machines mostly, and installing/dismounting bothers, and makes tower crane to realize fast-assembling.
Summary of the invention
The present invention is directed to deficiency of the prior art, provide a kind of can the tower crane of fast assembling-disassembling clump weight, the present invention Fast Installation can dismantle clump weight, under typhoon or other strong wind states, can pull down rapidly clump weight keep tower body steadily of centre of gravity, also solving clump weight in the past needs crane to install, and installation effectiveness is low, slow-footed problem, further, the present invention can also wrap clump weight when clump weight surprisingly drops, the problem preventing from clump weight from breaking rear splashing into pieces hurting sb.'s feelings.
In order to solve the problems of the technologies described above, the present invention is solved by following technical proposals: a kind of can the tower crane of fast assembling-disassembling clump weight, comprise pedestal, tower body, jacking stock, rotating table, crane arm, equilibrium arm and clump weight, described tower body is built by several standard knots, described jacking stock can move on described standard knot, described rotating table is arranged on described jacking cover top of the trellis, described crane arm and described equilibrium arm are arranged on described rotating table, described crane arm is relative with described equilibrium arm position, in described jacking stock, top is provided with counterweight jacking system, described counterweight jacking system can move up and down in described standard knot inside, described equilibrium arm is provided with the counterweight slideway matched with described counterweight jacking system, described equilibrium arm is also provided with the anchor fitting of fixing described clump weight and the airbag apparatus of the described clump weight of protection, described airbag apparatus comprise be arranged on bottom, described equilibrium arm top can the air bag of repeated inflation, described air bag is the cuboid of opening upwards, fast connection interface is provided with between described air bag and described equilibrium arm.
In technique scheme, preferably, described counterweight jacking system comprises lifter, described lifter is provided with some stay cords, described stay cord is provided with counterweight fixed way, described counterweight fixed way is provided with fixed way slideway, and described fixed way slideway slides is provided with several clump weight fixed mounts, described counterweight slideway is provided with the alignment device matched with described fixed way slideway.
In technique scheme, preferably, described alignment device electric rotation shaft, described electric rotation shaft is provided with connecting panel, described connecting panel is provided with the connection slideway coordinated with described fixed way slideway and described counterweight slideway, described connecting panel is also provided with several electric expansion limited posts, described fixed way is provided with the spacing hole matched with described electric expansion limited post.
In technique scheme, preferably, described spacing hole is tapered, inwardly reduces gradually from opening part.
In technique scheme, preferably, described clump weight fixed mount is provided with protection framework, drive motor and electronic locked piece.
