I The invention relates to lifting and handling equipment, namely to lifting devices for pipes.

The aim of the invention is to provide gripping of pipes of various diameters and lengths in cramped CONDITIONS.

FIG. 1 shows a load gripping device for pipes, a general view; in fig. 2 - view B in FIG. 1 (when seizing pipes of small diameter); in fig. 3 - the same, with the capture of large diameter pipes.

The load gripping device contains two L-shaped load-bearing elements | 1, connected by axis 2, interconnected interconnectedly by 3 times.

| water bearing elements 1. The lower poles of the bearing elements 1 have telescopic beams 4, the grips 5 are rigidly fixed to the ends of the extendable parts 6 of the beams 4. Telescopic I beams 4 are equipped with quick-release supports 7 for the load. Suspension 8 is connected to a hook of a lifting machine, for example with a tip of a manipulator.

Suspension device suspension works as follows.

Before starting the work, depending on the diameter of the pipes being lifted, the necessary stops 7 are installed, the necessary dilution of r 3 is provided for installation in. required angular position of the bearing elements 1

With the help of a lifting machine, the device is positioned above the pipes being gripped, and then,

.Q

-From the driver's cab, the beams 4 are synchronously raised. Sliding the outer surfaces of the grippers 5 along the walls of the gondola car, the stops 7 are lowered onto the pipes, the grippers 5 are inserted into the internal cavities of the pipes against the edges of the edges, and with different pipes taken simultaneously clamping of the pipes takes place sequentially: first, the longest, and then the shortest pipe, with their simultaneous self-centering relative to the longitudinal axis of symmetry of the device.

Claims (1)

Invention Formula A pipe gripping device containing beams, associated grippers, driving them along beams, load stops and suspension for attachment to a hook of a lifting machine, characterized in that in order to ensure gripping of pipes of various diameters and different lengths in constrained conditions x, it is provided with rigidly fixed, on beams and L-shaped supporting elements located in the transverse plane, the upper parts of which are hingedly connected to each other, and the lower parts are articulated by means of transverse adjustment emogo along the length of the connecting link, wherein the beams are telescopic, and the grippers are in the form of unilateral wedge and rigidly secured at the ends of the beams with the possibility of rotation in a fixed plane transverse to them.
