Description

(54) LOADING CAPTURE FOR TUBULARS

one

The invention relates to construction and can be used to grip pipes, preferably of large length, mounted in a vertical position during construction and installation works.

Known hinged pipe clamps, interacting with the binder, making reciprocating movement 1.

The disadvantage of the grippers is the complexity of the design, the length and inconvenience of loading and unloading.

Also known for lifting grip

for tubular products containing hollow

pole bar and articulated holders 2

The purpose of the invention is to provide turning the product and then moving it in a vertical plane.

To achieve this goal, the load-lifting gripper is provided with two contiguous coaxial disks arranged perpendicular to the longitudinal axis of the hollow rod, one of the disks being mounted on the hollow rod and having radial cutouts for the hinged holders which are fixed on the other disk.

FIG. 1 shows the device in the transport position, a general view; in fig. 2 - the same, in non-working position; in fig. 3 shows section A-A in FIG. one; in fig. 4 shows a section BB in FIG. 2 .;

5 Lifting grip for tubular products contains a hollow rod 1, tgu 2, hinged holders 3, equipped with two disks 4 and 5, located perpendicular to the axis of the hollow rod 1; one of the disks 4 is mounted on the hollow rod 1 and has radial notches 6 for hinged holders 3, which are fixed on the disk 5; on the hollow rod I, inside of which a ha 2 is passed, guides 7 and 8 are rigidly fixed; On disk 4 there are stops 9 and a protrusion 10, limiting the working position, stop 11 and radial cuts 6, which ensure the non-working position of the hinged holders 3.

The device works as follows.

Claims (2)

The load gripper is inserted into the cavity of the horizontally lying pipe 12 by guides 7 and 8 until the hinged holders 3 on the disk 5 with the base of the pipe 12 touch the horizontal position, after which it is transferred by a lifting device (not shown) to the vertical (transport) position. After lowering the pipe 12 to the installation site, the ha 2 weakens, the hinged holders 3 under the influence of the weight of the pipe 12 remain unresponsive, and the disk 4 lowers to the height of the protrusion 10, the disk 4 is rotated from the lower or upper ends of the hollow rod 1 to the stop 11, This cuts 6 are under the hinged holders 3. With subsequent tension 2, the hinged holders 3 are inoperative position and release the tube 12. The proposed device allows to reduce the time and increase the comfort during loading and unloading l long pipes, in addition, the device is easy to manufacture. Claims for tubular products containing a hollow rod with a pull and articulated holders, characterized in that in order to allow the product to tilt and then move it in a vertical plane, it is provided with two contiguous coaxial disks arranged perpendicular to the longitudinal axis of the hollow rod one of the disks is mounted on a hollow pole and has radial cuts for the hinge holders which are fixed on the other disk.
