Description
Technical field
The utility model relates to dynamic compaction machinery mounting technology field, particularly relates to a kind of dynamic compaction machinery basis jib group to frock.
Background technology
Along with Industrial Engineering maximizes and the development of hugeization, at equipment manufacturing, project installation aspect, lifted load is allowed to require progressively to improve to crane, crane or dynamic compaction machinery all utilize swing arm as supporting construction, but, along with the raising of lifted load, also more and more higher to swing arm requirement of strength, swing arm own wt also progressively improves, limit the raising of crane or dynamic compaction machinery lifted load to a certain extent, for this reason, some cranes maximized and dynamic compaction machinery all start to adopt steel truss type boom structure, on the one hand, steel truss structure is under the prerequisite that can meet support strength, sole mass declines greatly, in addition on the one hand, steel truss subsection setup, weight can be played according to difference and carry out length adjustment, expand the scope of application of crane, meet the requirement of equipment manufacturing and the maximization of project installation aspect and huge equalization.
The basic jib of general steel truss type swing arm comprises the web member that four rhizospheres become the chord member of truncated rectangular pyramids shape and are fixedly welded between four chord members, in concrete installation process, substantially the right mode of artificial group is adopted to weld at present, this kind of mode exists in the middle of making that jib linearity is overproof, overall package diagonal is overproof, angle is incorrect, group is inclined, can not exchange, production efficiency is low, the shortcomings such as high are required to craftsmanship, and the group affecting connector is scrapped causing time serious, causes waste of raw materials.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of dynamic compaction machinery basis jib group to frock, by using crossbeam, the three strings bar location of jib based on spacing column and hook, and the end position of two chord members being positioned at bottom can be determined according to the crossbeam at underframe two ends, namely the angle and position measuring and obtain web member is can be passed through after determining the position of three strings bar, and an other chord member is welded with fixing web member, complete the assembly welding of basic jib, by using this frock, can effectively improve assembly welding efficiency, improve the interchangeability of basic jib, reduce dynamic compaction machinery maintenance cost, improve basic jib linearity, overall package diagonal and angle, reduce the dependence to craftsmanship, improve assembly welding precision.
For solving the problems of the technologies described above, technical solution adopted in the utility model is: a kind of dynamic compaction machinery basis jib group is to frock, comprise at least two crossbeams that underframe, the spacing column of row being vertically arranged on underframe side and level are arranged on chassis top surface, the height of described spacing column reduces from left to right successively relative to underframe, horizontal bearing pin is installed on described spacing column top, the axis direction of bearing pin is identical with length over end sills direction, and described bearing pin fixedly mounts hook.
The quantity of described spacing column is identical with the quantity of crossbeam, and described crossbeam adopts channel-section steel, with welding of underframe and its length direction is vertical with length over end sills direction bottom it.
Described spacing column adopts channel-section steel to be vertically welded on above underframe, and channel-section steel upper end level wears bearing pin, and the split pin of bearing pin one end is fixed, its other one end fixed installation hook.
Described hook comprises shank and hook portion, and described shank is screw rod, and screw portion is arranged through the through hole of bearing pin one end, and overlaps nut with the supporting installation two of screw rod, and two cover nuts lay respectively at bearing pin both sides, and described hook portion is the arc shaped hook of a side opening.
The beneficial effect adopting technique scheme to produce is: by using crossbeam, the three strings bar location of jib based on spacing column and hook, and the end position of two chord members being positioned at bottom can be determined according to the crossbeam at underframe two ends, namely the angle and position measuring and obtain web member is can be passed through after determining the position of three strings bar, and an other chord member is welded with fixing web member, complete the assembly welding of basic jib, by using this frock, can effectively improve assembly welding efficiency, improve the interchangeability of basic jib, reduce dynamic compaction machinery maintenance cost, improve basic jib linearity, overall package diagonal and angle, reduce the dependence to craftsmanship, improve assembly welding precision.

Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
The utility model discloses a kind of dynamic compaction machinery basis jib group as shown in Figure 1-2 to frock, comprise at least two crossbeams 2 that underframe 1, the spacing column 3 of row being vertically arranged on underframe 1 side and level are arranged on underframe 1 upper surface, the height of described spacing column 3 reduces from left to right successively relative to underframe 1, horizontal bearing pin 4 is installed on described spacing column 3 top, the axis direction of bearing pin 4 is identical with underframe 1 length direction, and described bearing pin 4 fixedly mounts hook 5; The quantity of described spacing column 3 is identical with the quantity of crossbeam 2, and described crossbeam 2 adopts channel-section steel, welds and its length direction is vertical with underframe 1 length direction bottom it with underframe 1; Described spacing column 3 adopts channel-section steel to be vertically welded on above underframe 1, and channel-section steel upper end level wears bearing pin 4, and bearing pin 4 one end split pin is fixed, its other one end fixed installation hook 5; Described hook 5 comprises shank and hook portion, and described shank is screw rod, and screw portion is arranged through the through hole of bearing pin 4 one end, and overlaps nut with the supporting installation two of screw rod, and two cover nuts lay respectively at bearing pin 4 both sides, and described hook portion is the arc shaped hook of a side opening.
In embody rule process, the utility model is by using crossbeam, the three strings bar location of jib based on spacing column and hook, and the end position of two chord members being positioned at bottom can be determined according to the crossbeam at underframe two ends, namely the angle and position measuring and obtain web member is can be passed through after determining the position of three strings bar, and an other chord member is welded with fixing web member, complete the assembly welding of basic jib, by using this frock, can effectively improve assembly welding efficiency, improve the interchangeability of basic jib, reduce dynamic compaction machinery maintenance cost, improve basic jib linearity, overall package diagonal and angle, reduce the dependence to craftsmanship, improve assembly welding precision.
