Summary of the invention
The object of the present invention is to provide a kind of structure simple, easy to operate, and auxiliary tower crane disassemblerassembler that can improve tower crane climbing efficiency and preparation method thereof, to overcome the deficiencies in the prior art.
Technical scheme of the present invention: a kind of auxiliary tower crane disassemblerassembler, comprise standard section of tower crane and be arranged on the shaped steel stiffener on standard section of tower crane 4 root post, the lower floor and upper strata shaped steel stiffener of every root post fix respectively and has lower rectangular box and upper rectangular box, carriage is erected with using 4 lower rectangular box of 4 root post lower floors as fulcrum around 4 root posts, in the outside of carriage, chain connection has pair of supporting symmetrically, the outside of bracing frame is fixed in upper rectangular box by steel rope drawknot, each bracing frame is provided with one group and supports door frame, at support door frame internal fixtion, electric winch is installed.
Aforesaid lower rectangular box and upper rectangular box adopt screw to be connected and fixed by U-shaped clip and sealing bar and form, upper rectangular box is also provided with first otic placode fixing with steel rope drawknot.
Aforesaid carriage is provided with the second otic placode near bracing frame side, second otic placode is by the third ear plate chain connection inside bearing pin and bracing frame, have the 4th otic placode in the arranged outside of bracing frame, the 4th otic placode is fixed by the first otic placode drawknot on steel rope and upper rectangular box.
The present invention simultaneously also provides a kind of method for making above-mentioned auxiliary tower crane disassemblerassembler, first rectangular box and upper rectangular box under fixing respectively in the lower floor and upper strata shaped steel stiffener of the every root post of standard section of tower crane, then carriage is set up around 4 root posts using 4 lower rectangular box of 4 root post lower floors as fulcrum, the chain connection pair of supporting symmetrically in the outside of carriage again, the outside of bracing frame is fixed in upper rectangular box by steel rope drawknot simultaneously, then one group of support door frame is being installed on each bracing frame, finally at support door frame internal fixtion, electric winch is installed.
Aforesaid standard section of tower crane is the standard section of tower crane from the tower crane that climbs
A heavy load for aforesaid electric winch is 5T, is satisfied safe handling requirement, only allows the component of its lifting turnover 3T and following weight.
The invention has the advantages that: the bracing frame with electric winch is set up on standard section of tower crane by the present invention, so just, assist on K support, tower crane bracket by the tower crane pipe support needed for electric winch handling tower crane climbing, tower crane and bear down on one and other primary structural component, without the need to accounting for construction period main line, accelerating construction progress, saves construction cost.Meanwhile, because bracing frame is hingedly connected on carriage, therefore when not needing electric winch to carry out auxiliary handling, bracing frame can be drawn in standard section of tower crane, avoiding taking tower crane construction space.Therefore, the present invention not only structure is simple, easy to operate, and can improve tower crane and must to climb efficiency, does not affect construction period main line, accelerates construction speed, reduce construction cost and increase, be worth promoting in building operation industry.
