The invention relates to construction machinery, namely betonotransportnyh machines.

Known betonoraspredelitelnye arrow, including articulated folding partition installed on the mobile concrete installation [1] . The disadvantage of it is limited lifting height concrete/P> Also known arrow betonoraspredelitelnye Jack-up, including articulated folding section, the column located on its axis through the lifting sleeves with mounting rods, a supporting frame pivotally supported at their cylinders with lugs, coupled with mounting studs, concrete, plate of fastening of the concrete to the column [2].

This technical solution according to its technical essence and the achieved result is the closest to the proposal of the applicant and, therefore, adopted for the prototype.

The prototype is devoid of a lack analogues, because the height of the concrete or mortar that is associated with the height of the building is neogranichenoi due to the fact that the arrow with the column rise as building floors construction jobs.

However, the disadvantage of the prototype is the following. After each lifting by the lifting cylinders, at the end of the lifting column may deviate from the vertical by a certain amount in the plane perpendicular to the axis of the mounting rod, turning relative to the last.

The elimination of the specified skew columns (because normal Rautaruukki, by hand by driving the mounting wedges into the gap between the column and the base frame. Also a disadvantage is that it spoils the surface of the column.

Thus, the problem solved in this proposal is to reduce the complexity of the installation process of the column in a vertical position and reducing the possibility of damage.

The solution of the stated problem is achieved by the fact that the arrows concrete Jack-up, including articulated folding section, the column located on its axis through the lifting sleeves with placement of the mounting rods of the supporting frame pivotally supported on them by the hydraulic cylinders of the lifting eye connected with mounting studs, concrete, plate of fastening of the concrete to the column, one side wall of the column parallel to the longitudinal axes of lifting sleeves, fitted with adjustable height extra sleeve, designed to be installed in her mounting rod for engagement with the lifting cylinders, mounted on the side wall and located parallel to the longitudinal axes of lifting sleeves at a distance (A) from the axis of the fixing hydro which can be fixed on the side wall of the column by means of an intermediate bracket reinforced with bolted on the mounting plate of betnovate, located on the side wall; additional sleeve can also be mounted directly on the side wall by means of screw connection.

In Fig. 1 shows a General view of the boom betonoraspredelitelnogo Jack-up; Fig. 2 - fragment installation of the cylinder in connection with a mounting rod mounted in an additional sleeve with an intermediate bracket in side view; Fig. 3 - section b-B in Fig. 2, in Fig. 4 - slice install cylinder in connection with a mounting rod mounted in an additional sleeve without intermediate bracket, side view, Fig. 5 - section b-b of Fig. 4.

Arrow betonoraspredelitelnye Jack-up includes articulated folding section 1, column 2 located at its axis through the lifting sleeve 3 with mounting rods 4, is hosted by a support frame 5 is pivotally supported at their 6 cylinders with lugs 7 of the lifting columns 2 connected to mounting rods 4, the concrete pipes 8, the mounting plate of concrete pipes 9 to the column 2.

One of the side walls of the column 2, the parallel longitudinal axes of lifting sleeves 3, equipped with adjustable height extra sleeve 10. The sleeve 10 is fixed on backplane of concrete pipes 9. Additional sleeve 10 may be fastened to the side wall of the column by bolts 13 without intermediate bracket 11. Additional sleeve 10 is parallel to the longitudinal axes of lifting sleeves 3 at a distance from the axis of the fixing cylinder 6 to the support frame 5, a smaller length of cylinder fully extended rod.

Work on installation of the column 2 in the upright position is as follows.

At the end of the next rise of the column 2, the latter is fixed in the rearranged according to the height position of the mounting rod 15, which is passed through one of the lifting collet 3 and the lugs 16 of the base frame 5. The upper mounting rod 17 rearrange additional lifting the sleeve 10 and with him connect the hydraulic cylinder 6. By means of a flow of the working fluid in the piston or the rod end of the cylinder is put vertically in column 2 and fixed in the base frame 5 wedges. Upon completion of the work is taken out of the mounting rod 16 of the additional sleeve 10, the cylinder is cut along the length of the mounting rod 17 connects it with the corresponding lifting sleeve for the next rise.

After execution of the next rise an additional sleeve anitelea sleeve 10 with the column 2 - with the intermediate bracket and without it, depending on what is deemed more appropriate in the operation.

The proposed design will allow with the lowest complexity without damaging the surface of the column to display the column in the upright position.
