Design feature of the present invention also is:
also be provided with lower edge square tube detent mechanism on described framework platform, 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 between right plate forms, a described left side, right plate has level trough near the top correspondence, and be provided with upward opening in a side, described bearing pin embeds in level trough by upper opening, the jacking apparatus that is fixed on base is used for from bottom surface jack-up lower edge square tube, jacking apparatus be fixed on the lower edge square tube directly over bearing pin coordinate, the lower edge square tube is carried out vertical direction locates, described left plate middle part is provided with screwed hole, and described screwed hole coordinates with screw rod and is used for holding out against to locate the lower edge square tube from sidepiece.
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 the crane arm lower boom need to carry out the variable cross-section assembly unit, only need to change the embedded module of lower contact positioning support, change the standardized module of corresponding specification, can easily realize the smooth transition of variable cross-section joint.
2, lower contact positioning support of the present invention adopts the dual-sided board structure, and in lower contact was inserted in dual-sided board, then the bearing pin hallway was located, the one-sided location of lower contact before efficiently solving, the problem that the location is inaccurate.
3, the present invention has increased lower edge square tube positioning support structure, by this detent mechanism, the lower edge square tube is carried out vertical, horizontal both direction and accurately locates, and has effectively guaranteed the linearity of lower edge square tube, has reduced the crane arm integral installation timing improvement time.

Number in the figure: 1 framework platform, 2 wall panel assemblies, 3 wind up and manage positioning support, 4 lower edge square tube positioning supports, 5 top connection positioning supports, 6 lower contact positioning supports, 7 square holes, 8 standardized modules, 9 bases, 10 left plates, 11 right plates, 12 bearing pins, 13 gripper shoes, 14 level troughs, 15 openings, 16 screwed holes, 17 jacking apparatus, 18 lower edge square tubes.
The present invention is further described below in conjunction with accompanying drawing.
The specific embodiment
as shown in the figure, the crane boom frock, comprise a framework platform 1, detachably be fixed on wall panel assembly 2 and a plurality of pipe positioning support 3 that winds up of horizontal frame platform 1 left and right sides, 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, on the dual-sided board of top connection positioning support, correspondence is provided with pin shaft hole, on the dual-sided board of lower contact, correspondence is provided with square hole 7, square hole 7 is used for the standardized module 8 of fixed installation 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 be fixed with bolt, when crane arm need to carry out the variable cross-section transition, only need to change and think corresponding module, can realize.
as shown in Fig. 5-7, also be provided with lower edge square tube detent mechanism on framework platform, comprise lower edge square tube positioning support 4 and jacking apparatus 16, 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 the top correspondence, and be provided with upward opening 15 in a side, bearing pin 12 embeds in level trough by upper opening, be fixed on jacking apparatus 16 on base 9 from bottom surface jack-up lower edge square tube, jacking apparatus be fixed on the lower edge square tube directly over bearing pin coordinate, the lower edge square tube is carried out vertical direction locates, described left plate middle part is provided with screwed hole 16, and described screwed hole coordinates with screw rod 17 and is used for holding out against to locate the lower edge square tube from sidepiece.
During use, adjust two wallboard spacings, after up and down nipple orifice center distance satisfies 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 the crane arm assembly unit, at first lower edge square tube 18 is hung in the lower edge positioning support, after putting into level trough location upper surface with bearing pin, jacking apparatus jack-up, puller bolt coordinates simultaneously, and the vertical and horizontal direction of lower edge square tube is located simultaneously.In the time of can effectively solving like this frock assembly unit in the past, lower edge square tube upper surface is in the problem of free state.Then a section lower contact inserts in the lower edge square tube, and insert in the lower contact positioning support other end, and the rear point in frock bearing pin hallway location is solid, the problem that before can effectively controlling like this, lower contact location in one-sided location is forbidden.
In sum, one aspect of the present invention can realize the precise positioning of lower contact and the smooth transition in variable cross-section docking situation, well controlled on the other hand crane arm in the distortion of welding process lower edge square tube lateral surface and upper surface, for providing of amplitude variation trolley good service condition.In addition, all do accurate positioning control due to jib for tower crane frock of the present invention butt joint and chord member, effectively guaranteed the linearity of the whole docking of crane arm, greatly reduced the workload of correcting, improved production efficiency.
