In order to address the above problem, the rig that is used to reclaim the tower crane screw rod of the present utility model, comprise base, the column guide rail, slide, motor and hosqe bit, wherein, the lower end of column guide rail is fixed on the base, on this column guide rail, be with described slide, this slide moves up and down along the column guide rail by elevating mechanism, described motor is installed on this slide, the output shaft of this motor links to each other with described drill bit, and the center line of this drill bit is parallel with the center line of column guide rail, and described column guide rail is a hollow-core construction, is provided with pressing plate in the upper end of this column guide rail, and in this column guide rail, hollow core bar is housed, the lower end of this core bar is fixedly connected with lower nut, and described pressing plate is stretched out and the top nut that has been threaded in the upper end of this core bar on this extension, and this top nut is locked at described pressing plate the upper end of described column guide rail.
In technique scheme, the lower end of described column guide rail is concordant with the soffit of described base.
In technique scheme, the area of described pressing plate is greater than the area of described column track cross-section.
In technique scheme, the internal diameter of described core bar is more than or equal to the internal diameter of described lower nut.
In technique scheme, described elevating mechanism mainly is made of the tooth bar on gear in the described slide and the described column guide rail, and gear and tooth bar are formed gear pair, and this gear is supported by the turning cylinder on the slide, this turning cylinder stretches out slide, and on extension handle is housed.
As the preferred embodiment of technique scheme, be welded with sleeve pipe in the upper end of described core bar, the axial line of this sleeve pipe is vertical with the axial line of described hollow core bar, and the length of sleeve pipe is less than the diameter of described hollow core bar.Pass sleeve pipe with a bar like this, drive hollow core bar rotation, can reach the labour-saving purpose by rotating this bar.
Compared with prior art, the beneficial effects of the utility model are: can take out basic screw rod easily, it is low to take out cost; And the basic screw rod of taking-up can reuse, and has saved the wasting of resources.
