Design feature of the present invention is also:
Described framework platform is also provided with lower edge square tube detent mechanism, described lower edge square tube detent mechanism comprises lower edge square tube positioning support and jacking apparatus, described backspin square tube positioning support is by base, be vertically fixed on the left side on base, right plate, bearing pin, and be located at a left side, gripper shoe composition between right plate, a described left side, right plate has level trough near top correspondence, and be provided with upward opening in side, described bearing pin embeds in level trough by upper opening, be fixed on jacking apparatus on base for from bottom surface jack-up lower edge square tube, jacking apparatus be fixed on lower edge square tube directly over bearing pin coordinate, vertical direction location is carried out to lower edge square tube, be equipped with screwed hole in the middle part of described left and right side plate, described screwed hole coordinates with screw rod and is used for holding out against to locate lower edge square tube from both sides, front and back.
Compared with prior art, beneficial effect of the present invention is embodied in:
1, the present invention is in the design of wallboard lower contact positioning support, adopt modularized design, when crane arm lower boom need to carry out variable cross-section assembled time, only need change the embedded module of lower contact positioning support, change the standardized module of corresponding specification, easily can realize the smooth transition of variable cross-section joint.
2, lower contact positioning support of the present invention adopts dual-sided board structure, and lower contact is inserted in dual-sided board, then bearing pin hallway location, the one-sided location of lower contact before efficiently solving, the problem that location is inaccurate.
3, invention increases lower edge square tube positioning support structure, by this detent mechanism, vertical, horizontal both direction is carried out to lower edge square tube and accurately locate, effectively ensure that the linearity of lower edge square tube, decrease the crane arm integral installation timing improvement time.

Detailed description of the invention
As shown in the figure, crane boom frock, comprise a framework platform 1, detachably be fixed on the wall panel assembly 2 of horizontal frame platform 1 left and right sides and multiple pipe positioning support 3 that winds up, lower edge square tube positioning support 4, wall panel assembly 2 is provided with the upper of left and right dual-sided board structure, lower contact positioning support 5, 6, in the dual-sided board of top connection positioning support, correspondence is provided with pin shaft hole, in the dual-sided board of lower contact, correspondence is provided with square hole 7, square hole 7 is for fixedly mounting the standardized module 8 of different size, the different size of standardized module refers to that disparate modules is provided with the pin shaft hole of differing heights, standardized module is embedded in square hole, and fix with bolt presses, when crane arm needs to carry out variable cross-section transition, only need change and think corresponding module, can realize.
As illustrated in figs. 5-7, framework platform is also provided with lower edge square tube detent mechanism, comprise lower edge square tube positioning support 4 and jacking apparatus 17, backspin square tube positioning support is by base 9, be vertically fixed on the left side on base, right plate 10, 11, bearing pin 12, and be located at a left side, gripper shoe 13 between right plate forms, left, right plate has level trough 14 near top correspondence, and be provided with upward opening 15 in side, bearing pin 12 embeds in level trough by upper opening, be fixed on jacking apparatus 17 on base 9 from bottom surface jack-up lower edge square tube, jacking apparatus be fixed on lower edge square tube directly over bearing pin coordinate, vertical direction location is carried out to lower edge square tube, be equipped with screwed hole 16 in the middle part of described left and right side plate, described screwed hole 16 coordinates with screw rod 19 and is used for holding out against to locate lower edge square tube from both sides, front and back.
During use, adjust two wallboard spacing, after upper and lower nipple orifice center distance meets drawing requirement, fixing wallboard.Then adjust both sides lower boom positioning support, make its positioning reference plane and lower contact positioning reference plane point-blank.When carrying out crane arm and being assembled, first hang in lower edge positioning support by lower edge square tube 18, after putting into level trough inner position upper surface with bearing pin, jacking apparatus jack-up, puller bolt coordinates simultaneously, locates the vertical of lower edge square tube and horizontal direction simultaneously.When before can effectively solving like this, frock is assembled, lower edge square tube upper surface is in the problem of free state.Then one of lower contact section is inserted in lower edge square tube, other end is inserted in lower contact positioning support, and behind frock bearing pin hallway location, point is solid, the problem that before can effectively controlling like this, lower contact location in one-sided location is inaccurate.
In sum, one aspect of the present invention can realize the smooth transition in the precise positioning of lower contact and variable cross-section docking situation, well control on the other hand crane arm in welding process lower edge square tube lateral surface and upper surface distortion, provide good service condition for amplitude variation trolley.In addition, because Tower crane boom tool butt joint of the present invention and chord member have all done accurate positioning control, effectively ensure that the linearity of crane arm entirety docking, greatly reduce the workload of rectification, improve production efficiency.
