A kind of jib for tower crane frock, comprise a framework platform, detachably be fixed on wall panel assembly and a plurality of pipe positioning support that winds up of the framework platform left and right sides, lower edge square tube positioning support, its design feature is, described wall panel assembly be provided with left and right sides dual-sided board structure on, the lower contact positioning support, correspondence is provided with pin shaft hole on the dual-sided board of described top connection positioning support, correspondence is provided with square hole on the dual-sided board of described lower contact, described square hole is used for the standardized module of fixed installation different size, and the different size of described standardized module refers to that disparate modules is provided with the pin shaft hole of differing heights.
Design feature of the present invention also is:
Also be provided with lower edge square tube detent mechanism on the 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 the base, right plate, bearing pin, and be located at a left side, gripper shoe between the right plate is formed, 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 the level trough by the top opening, the jacking apparatus that is fixed on the 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 cooperate, the lower edge square tube is carried out vertical direction location; Described left plate middle part is equipped with screwed hole, and described screwed hole cooperates 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 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 reduced section sub.
2, lower contact positioning support of the present invention adopts the dual-sided board structure, and in lower contact was inserted in the dual-sided board, bearing pin hallway location efficiently solved the one-sided location of lower contact in the past, the problem that the location is inaccurate then.
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 locatees, 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 be provided with left and right sides dual-sided board structure on, lower contact positioning support 5,6, correspondence is provided with pin shaft hole on the dual-sided board of top connection positioning support, correspondence is provided with square hole 7 on the dual-sided board of lower contact, 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 the square hole, and be fixed with bolt, when crane arm need carry out the variable cross-section transition, only need to change to think corresponding module, can realize.
Shown in Fig. 5-7, also be provided with lower edge square tube detent mechanism on the 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 the base, right plate 10,11, bearing pin 12, and be located at a left side, gripper shoe 13 between the right plate is formed, a left side, 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 the level trough by the top opening, be fixed on jacking apparatus 16 on the 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 cooperate, the lower edge square tube is carried out vertical direction location; Described left plate middle part is equipped with screwed hole 16, and described screwed hole cooperates with screw rod 17 and is used for holding out against to locate the lower edge square tube from front side portion.
During use, adjust two wallboard spacings, treat that up and down the nipple orifice center distance satisfies the drawing requirement after, fixing wallboard.Adjust both sides lower boom positioning support then, make its location datum level and lower contact location datum level 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, put into level trough location upper surface with bearing pin after, jacking apparatus jack-up, puller bolt cooperates simultaneously, and the vertical and horizontal direction of lower edge square tube is located simultaneously.Lower edge square tube upper surface is in the problem of free state in the time of can effectively solving frock assembly unit in the past like this.Lower contact one section inserts in the lower edge square tube then, and insert in the lower contact positioning support other end, and back, frock bearing pin hallway location point is solid, the inaccurate problem in one-sided location lower contact location before can effectively controlling like this.
In sum, one aspect of the present invention can realize the accurate location of lower contact and the smooth transition under the variable cross-section butt joint situation, on the other hand better controlled 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, because jib for tower crane frock of the present invention butt joint and chord member have all been done accurate localization control, effectively guarantee the linearity of the whole butt joint of crane arm, significantly reduced the workload of correcting, improved production efficiency.
