Abstract
The utility model belongs to the technical field of machine manufacturing, and provides a crane high strength cargo boom which is formed by an upper cover plate, a lower cover plate and two side plates. The upper cover plate is a surface plate, the side plates are formed by vertical plates, upper surface plates and lower oblique plates, and the lower cover plate is formed by a lower surface plate and an upper oblique plate. The upper cover plate, the lower cover plate and the two side plates are enclosed into a hexagon section structure. When the crane high strength cargo boom is manufactured, the upper cover plate, the lower cover plate and the two side plates are clamped and mounted through moulds and are assembled into the hexagon, and then are welded by welding two sides simultaneously through an automatic welding machine. Therefore, good depth of parallelism and planeness of the structure can be well guaranteed, and the technical requirements are guaranteed. Strength and stiffness of the cargo boom are improved, the ability that slide blocks bear partial extruding strength is increased, welding process is good, appearance is attractive, and size under constant strength is small.
Description
Technical field
The utility model belongs to machinery manufacturing technology field, is specifically related to a kind of crane crane arm.
Background technology
Existing crane crane arm cross section mainly with four, five, hexagon is main, with regard to its intensity and aesthetic property, adopts the rhombus hexagonal cross-section more, rhombus hexagon manufacture craft is poor, the same strength lower volume is large; Middle weld seam hexagon welding deformation is large, and upper and lower slide block place local strength is difficult to guarantee.
The utility model content
The technical problems to be solved in the utility model provides a kind of crane high strength crane arm.
The scheme of the utility model technical solution problem is to adopt upper cover plate, lower cover and two side plates consist of crane high strength crane arm, upper cover plate is surface plate, side plate is by riser, upper flat plate and declined board form, riser is vertical with upper cover plate, upper flat plate is at the riser top, inwardly bending 90 is spent, the top of two blocks of upper flat plates about upper cover plate is fixed on, the width of upper cover plate with about the width of two risers identical, declined board is in riser bottom, inside below bending 50-70 degree, and lower cover is made of lower flat board and inclined board, lower flat board is vertical with riser, inclined board is in lower dull and stereotyped both sides, bending 50-70 degree upwards, and the angle of inclined board bending is identical with the angle of declined board bending, inclined board is fixed on declined board bottom, upper cover plate, lower cover and two side plates surround the hexagonal cross-section structure.During making,, weld simultaneously with the automatic are welding machine both sides again and finish becoming hexagon by the clamping mould group, better guaranteed this well-formed's parallelism and planeness; Guarantee technical requirements.
The new crane arm strength and stiffness that improve of this practicality, the ability that the slide block place overcomes local crushing strength strengthens, and welding process is good, aesthetic in appearance, the equal strength lower volume is little.
