After adopting such a structure, when the introduced standard knot is basically vertical to the lower tower body standard knot, the eyelets of the upper and lower connecting sleeves are basically aligned, and at the moment, a worker inserts the connecting bolt into the connecting sleeve and lightly beats the connecting bolt to enable the connecting bolt to quickly penetrate through the eyelets of each group of two connecting sleeves. Particularly, after the last standard knot is installed, the eyelets of the upper sleeve and the lower sleeve cannot be completely centered when the lower support of the rotary mechanism is connected with the standard knot, and the illegal operation that the alignment of the eyelets of the connecting sleeves is adjusted by using a rotary crane boom under the common condition is avoided. The technology of aligning the holes of the connecting sleeve of the standard joint by using the cone of the connecting bolt induces the holes of the connecting sleeve of the standard joint, the working efficiency of tower crane installation is improved greatly, and the accident potential caused by the problems of crane arm balance adjustment and rotation in the installation process is reduced.
The connecting bolt of the tower crane standard knot verticality guiding and fixing structure comprises two nuts, wherein the two nuts are respectively a locking nut and an anti-skidding nut, the locking nut is matched with a screw rod of the connecting bolt, the locking nut is abutted against a corresponding connecting sleeve, the anti-skidding nut is matched with the screw rod of the connecting bolt, and the anti-skidding nut is abutted against the locking nut; after adopting such structure, the antiskid nut can slow down lock nut and take place not hard up situation when daily use, increases this tower crane standard festival straightness guide fixed knot structure security of hanging down.
The side wall of each connecting sleeve of the tower crane standard knot verticality guiding and fixing structure is provided with a limiting pin shaft hole along the radial direction, the side wall of each connecting bolt is provided with a kidney-shaped hole, each U-shaped stud bolt comprises a stud bolt and two nuts, two end parts of the stud bolt of each U-shaped stud bolt respectively penetrate through the limiting pin shaft holes of each group of two connecting sleeves and the kidney-shaped hole of each connecting bolt, and the stud bolts are respectively matched with the two nuts; after adopting such structure, U-shaped stud runs through connecting sleeve and connecting bolt respectively and locks the two once more, further increases the fixity that two tower crane standard festival connect, promotes the security.

Detailed Description
Example one
As shown in fig. 1 to 2
This tower crane standard festival straightness guide fixed knot that hangs down has four connecting sleeve 11 in tower crane standard festival 1 upper and lower part welding respectively, eight connecting sleeve 11 distribute in tower crane standard festival 1 inboardly, four connecting sleeve 11 of the upper and lower side are the rectangle form respectively and distribute in tower crane standard festival 1, every connecting sleeve 11 constitutes a set of connecting sleeve 11 with the corresponding connecting sleeve 11 of its adjacent tower crane standard festival 1, a plurality of connecting bolt are the one-to-one with a plurality of group connecting sleeve 11, connecting bolt runs through a set of connecting sleeve 11 of two adjacent tower crane standard festival 1.
The connecting bolt comprises a screw 12a and two nuts, the end of the screw 12a of the connecting bolt extends out of the corresponding group of connecting sleeves 11, the end of the screw 12a of the connecting bolt is in a frustum shape, the two nuts are respectively a locking nut 12b and an anti-slip nut 12c, the locking nut 12b is matched with the screw 12a of the connecting bolt, the locking nut 12b is abutted against the corresponding connecting sleeve 11, the anti-slip nut 12c is matched with the screw 12a of the connecting bolt, and the anti-slip nut 12c is abutted against the locking nut 12 b.
