Abstract
The invention discloses a basic arm rack assembly tooling of a dynamic compactor. The basic arm rack assembly tooling comprises a bottom rack, a column of limit stand columns which are vertically mounted on one side of the bottom rack, and at least two transverse beams which are horizontally mounted on the upper surface of the bottom rack, wherein the heights of the limit stand columns sequentially decrease from left to right relative to the bottom rack,; a horizontal pin shaft is mounted at the top end of each limit stand column; the axial direction of each pin shaft is the same as the length direction of the bottom rack; a holding hook is fixedly mounted on each pin shaft. The transverse beams, the limit stand columns and the holding hooks are positioned as three chord rods of basic arm racks, and after the positions of the three chord rods are determined, the angles and the positions of the web rods can be obtained through measurement; another chord rod is welded to the fixed web rods, so that the assembled welding of the basic arm racks is completed. Through the adoption of the basic arm rack assembly tooling, the assembled welding efficiency can be effectively improved; the interchangeability of the basic arm racks is improved; the maintenance cost of the dynamic compactor is reduced; the straightness accuracy, and the entirely assembling diagonal lines and angles of the basic arm racks of the basic arm racks are improved; the dependence on skills of workers is reduced, and the assembled welding precision is improved.
Description
Technical field
The present invention relates to dynamic compaction machinery mounting technology field, particularly relate 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.
Summary of the invention
Technical problem to be solved by this invention 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, the technical solution used in the present invention 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.
