(54) CRANE-PIPE (57) Usage: The invention relates to devices for mounting and transporting pipes using a pipe-laying machine and can be used for mounting

engineering communications. SUMMARY OF THE INVENTION: The crane-pipe-laying machine is provided with a frame hinged at one end at the base of the boom, pivoting in the vertical plane with stops mounted on the upper surface of the frame at its free ends, fixed stops installed between the pivoting and boom, with an eye placed on the bottom surface of the frame an additional line for bending the pipe, one end of which is connected to the eye and the other to the hook. 11 il.

The invention relates to devices for transporting and installing pipes with a crane-pipelayer and can be used for the installation of engineering communications,

Known crane laying pipe containing a cargo boom, pivotally attached to the slider

crane crane and equipped with a cargo and boom hoists and lifting body, a winch and a counterweight (counter-load). The load lifting mechanism, the mechanism for changing the boom overhangs and movements provide the necessary working movements.

A disadvantage of the known pipe-laying crane is that during transportation of pipes it is necessary to use manual labor of slingers to keep the pipes from swaying, as well as possible damage to the insulation of the pipes during slinging and possible blows of the pipes against the pipelayer during transportation.

The aim of the invention is to increase work efficiency by increasing the productivity during transportation.

Comparative analysis with the prototype shows that the proposed crane-pipelayer is characterized in that it is provided with a frame hinged at one end at the base of the boom, vertical stops pivoting on the upper surface of the frame at its free ends, fixed stops installed between swivel and boom, eye, placed on the bottom surface of the frame, and an additional sling for bending the pipe, one end of which is connected to the eye, and the other with a hook. Thus, the claimed device meets the criteria of the invention of novelty and significant difference.

FIG. 1 shows the crane in a transport position; in fig. 2 is a diagram of slinging a pipe located on the ground in the initial position; Fig. 3 is a diagram of the pipe ramming onto the frame; in fig. 4 - the position of the pipe while supporting it on the fixed stops; figure 5 - position

pipes with the greatest rise of the cargo polyspast, in FIG. 6 - the position of the pipe during transportation; in fig. 7 - pipe position with the line removed and the frame lowered; FIG. 8 shows the position of the pipe when lowering it to the design elevation; FIG. 9 shows the node I in FIG. 7, in FIG. 10 — node II in FIG. 9, in FIG. 11 is a view A of FIG. five.

The crane-paver contains boom 1, system of inclination 2 booms and cargo polipast 3 attached to the tip of the boom 1. At the bottom of the arrows 1 are fixed cheeks 4, in which frame 6 with an eye 7 is hinged on the axis 5. the plane of the frame 6 is placed damping pads 8 made of elastic material, for example rubber, at the hinged base of the frame 6 there are stationary stops 9, fitted with damping pads 10, at the end of the frame 6 - vertical supports pivoting in axes 12 and tied up compressors 13 operating with springs 13 By means of a sling-mounting device 15, such as a moto-towel, is attached to the hook 16 of the cargo hoist 3 For the hook 16 there is attached one end of the sling 17, which bends around the mounting and mounting device 15 and fastens the other the end of the eyelet 7 For fixing the frame 6 in the transport polo / UU

On the boom 1, the lugs 18 are secured with the fingers 19, and in the fixed stops 9 there are holes 20 for mounting the fingers 19.

The use of this crane-paver allows for work to be carried out without the use of manual labor by slingers during the transportation of pipes, while rocking the pipes and striking the pipe-laying machine is prevented, and also ensures that the pipes are flawlessly fixed.

Claims (1)

The invention of the crane-pipelayer containing the boom with a cargo tackle and hook and boom tilting system, characterized in that, in order to increase efficiency in operation by reducing the time to transport the pipe, it is equipped with a platform for placing the pipe that is articulated by one side at the bottom of the boom and made with stops to hold the pipe, one of which is installed at the opposite first side of the platform with the possibility of rotation in the vertical plane, while the others are fixed between the first and stops and the boom placed on the bottom surface thereof and a lanyard eyelet to enclose pipes, one end of which is connected to a pad eye, and the other - with the hook. oo oo with to r-.  S "o with co g: GO  / //////////// 7 /, Phage. five  ////////////////////// 7 / f Figb P  //////////// ////// 77 ///////////////////// 0 V Ste.7 -i l J8 Ste.7 ////// J / W ////// FIG. b 77 / s / Phage. 9 77 eight Fi.Y. 1813 / J Btida I / 9189 74 LI / /
