Description
Technical field
The utility model relates to technical field of crane equipment, is specifically related to jack-up system under a kind of two oil cylinders of weight-lifting equipment.
Background technology
When using electric power pole to carry out electric power tower installation exercise, generally all adopt down jack-up system.Existing lower jack-up system, more employing list cylinder jacking, and need the introduction operation repeatedly changing step just can complete a standard knot.Also the lower jack-up system had have employed two cylinder jacking, but owing to lacking supporting climbing structure processing scheme, rely on the synchro control of hydraulic efficiency pressure system synchronous to ensure that twin-tub is elevated completely, require high to hydraulic efficiency pressure system, operation easier is large, and still there is the deficiency of multistep jacking.In addition.When the higher situation decline tower operation of electric power pole setting height(from bottom), owing to there is multilayer attachment, it is asynchronous with the motion of oil cylinder that tower body and the friction drag of attachment frame guide piece may cause tower body structure to decline, and lower jack-up system uses common claw structure to there is potential safety hazard.
Utility model content
The utility model object is to provide jack-up system under a kind of two oil cylinder, solves in prior art and needs multistep jacking just can complete the introduction operation of a standard knot, manual operation amount is large, working security is low technical matters.
For realizing above-mentioned technical purpose, the utility model takes following technical scheme:
Jack-up system under a kind of two oil cylinder, comprise jacking stock, jacking frame, jacking cylinder and underframe, described jacking stock is positioned at tower body root and is enclosed in the outside of tower body, jacking frame is provided with in the horizontal direction between jacking stock and tower body, the interior empty size of jacking frame and the contour dimension of tower body adapt, the jacking cylinder of jacking frame and bottom is connected and fixed, and it is characterized in that: described jacking cylinder comprises around symmetrically arranged two jacking cylinders of tower body; The bottom of the cylinder barrel of jacking cylinder is fixed on underframe, and the head of cylinder barrel is connected with jacking stock by additional support structure, and the rod end of the piston rod in cylinder barrel is connected with jacking frame; Described jacking frame with between tower body by can the bearing pin of changing step of pull realize being connected or throwing off, jacking frame is under the effect of jacking cylinder, and independence or drive tower body carry out vertical lift between the upper and lower two-layer guide wheel of jacking stock; The bottom of described jacking stock is fixed on underframe.
Preferred further, draw cable wind rope between the top of described jacking stock and earth anchor.
Further, described cylinder barrel and underframe Flange joint.
Further, the top of described piston rod is connected by pivot pin with the bottom surface of jacking frame.
Further, be connected by the axial motion of the bearing pin of changing step arranged in the horizontal direction or throw off between described jacking frame with the main string of tower body, described tower body is welded with marking time of hole of marking time with the matching used band of bearing pin of changing step, described in mark time hole axis in the horizontal direction, along being vertically Long Circle.
Further preferred, described jacking frame and tower body are connected with symmetrically arranged at least two to bearing pin of changing step.
Preferred further, described additional support structure comprises the horizontal otic placode one of the cross rail inner being connected to jacking stock and is welded on the horizontal otic placode two of head periphery of cylinder barrel of jacking cylinder, and described horizontal otic placode one is connected by connecting pin axle with horizontal otic placode two.
Preferred, described horizontal otic placode one comprises upper and lower two otic placodes, and described horizontal otic placode two is clipped between upper and lower two otic placodes.
Compared with prior art, technical advantage of the present utility model is:
1, the utility model is by the top lift of the rod end of bilateral oil cylinder, is delivered on tower body by a jacking mount structure.Utilize the structural strength of jacking frame to realize the secondary distribution of top lift, what be conducive under two oil cylinder in lifting operation is synchronous, improves the safety of lifting operation;
