Boom hoisting machine
(57) Abstract:Usage: the machine for loading, excavation and other works associated with the lifting, and the development and movement of soil, in particular shovel loaders. The inventive boom hoisting machine consists of two connected curved towards each other by the edges of the mounting holes on the ends of the sidewalls and eyelets for attaching the boom to the base machine. The arrow is made of two parts that are installed end sections, the opposite end section with the mounting holes in one another. The first part is intended for fastening to the base machine and consists of two cheeks. Cheeks fastened in the lower part of the sheet and have the counter fractures in the upper and lower parts. The second part is set in the first and in the form of two l-shaped sides connected with the formation of the U-shaped profile, bound with two leaves. The first sheet is secured along the junction and overlapping, and the second is attached to the bottom nasagot parts of the sidewalls and executed in length, overlapping the first sheet side of the boom at the junction of the two parts. The eyelet is attached to the second part of the boom. 3 and the other works associated with the lifting, and the development and movement of soil, namely, to machines of the type shovel loaders.Known for boom hoisting machine, consisting of two connected curved towards each other the edges of the side walls with mounting holes at the ends of the boom for securing it to the base machine to handle and lugs for attaching the hydraulic cylinder control handle (see U.S. patent N 4997333, CL E 02 3/36, publ. 1991).A disadvantage of known construction boom is that its sidewall with upper and lower curves cut out from a sheet metal complex markup, because you must razmeritei and the corresponding bend solid sidewall.The basis of the invention the task is improving the boom hoisting machine, which by its design changes is to simplify its design and technologies, such as manufacturing and Assembly, and due to this cost reduction.The problem is solved in that in the boom hoisting machine, consisting of two connected curved towards each other the edges of the side walls with mounting holes at the ends of the arrows the ACLs to the invention, the boom is made of two parts, installed end sections to the opposite end sections with mounting holes in one another, with the first part, intended for fastening to the base machine is made of two cheeks fastened at the bottom and having in the area of the entrance is the second part of the counter-fractures in the upper and lower parts, and the second part installed in the first, made of two connected l-shaped sides with the formation of the U-shaped profile is additionally bonded to each other by means of two sheets, one of which is attached along and overlapping the junction of the l-shaped side walls, and the second is attached to the bottom nasagot parts on both sides and made of length overlying the first sheet portion in the zone of connection of the two parts of the boom, while the eyelet fastening cylinder control handle attached to the second part of the boom.Due to the fact that the arrow is made of two parts that are installed end sections opposite end portions with the mounting holes in one another, the first part is made of two cheeks, fastened in the lower part of the sheet, the second part is formed with l-shaped sides, fastened at the top and bottom of the two sheets and the bottom sheet overlaps l is led to additional bending of the sidewalls. The opportunity to make each sidewall and hence the arrow from two parts, which leads to more complete utilization of the metal sheet from which the cut out sides, simplifies the process of formation of the sidewalls.In Fig. 1 shows the boom hoisting machines, top view; Fig.2 is a side view, and Fig.3 section a-a of Fig.1.The boom load lifting machine comprises two l-shaped sidewall 1 and 2 with curved towards each other by the edges 3 and 4. At the ends of the boom with holes 5 for fastening to the base car, 6 for attachment to the handle. Lug 7 has a hole 8 for mounting the hydraulic cylinder control handle. The arrow is made of two parts 9 and 10 mounted end sections of one another. Part of the boom 9 has two cheeks 11 and 12, which are fastened at the bottom of the sheet 13. Cheeks in the area of the input part 10 is made with counter bends, bevels, 14 and 15. Sides 1 and 2 in the upper part sealed with the sheet 16 is welded to the ceiling and along their interface, and the bottom sheet 17. The sheet 17 is made overlying the sheet 18.The manufacture and Assembly of the arrows as follows. From a sheet of metal cut out separately sides 1 and 2 and cheeks 11 and 12, in the cheeks 11 and 12 perform ostium 6, weld the sheet 16, and then the sheet 17. Fabricated parts 9 and 10, insert one into the other. Part 10 is inserted into the part 9 and rigidly fastened to each other, for example by welding, along the lines 15 and 14.Made arrow has a simpler construction as compared with the known, which were moving up and down sides in front of their dock. Facilitates the Assembly of the boom, more fully consumes the material when the pattern of boom members. Boom hoisting machine, consisting of two connected curved towards each other the edges of the side walls with the mounting holes on the ends of the sides for attaching the boom to the base machine and the handle, lugs for attaching the hydraulic cylinder control handle, wherein the bolt is made of two parts that are installed end sections, the opposite end sections with mounting holes, one to another, with the first part, intended for fastening to the base machine is made of two side cheeks, fastened in the lower part of the sheet and having in the area of the entrance is the second part of the counter-fractures in the upper and lower parts, and the second part installed in the first, made of two connected l-shaped sides with the formation of P-n along and overlapping the junction of the l-shaped side walls, and the other attached to the bottom nasagot parts on both sides and made of length, overlapping the first sheet portion in the zone of connection of the two parts of the boom, while the eyelet fastening cylinder control handle attached to the second part of the boom.
