The invention relates to a lifting and transport equipment, in particular to a gripping device for pipes, and is an improvement of the known device according to the author. St. No. 1273329.

The purpose of the invention is to reduce the metal content.

FIG. 1 shows a gripping device D.GYY pipes, front view; in fig. 2 - the same, side view.

When the gripper is mounted on a row of pipes, the main winch articulated by cables 12 with flexible element 11 is lifted. The force of the lifting machine through fixed blocks 4 and movable blocks 8 connected to sliders 7 is transmitted to rigid rods 15 connected hingedly to a slider 16 , and on additional rigid rods 19, pivotally connected at one ends with a short Pickup device for pipes, contains 10 arms of L-shaped levers 18, and the other, rectangular multi-section frame 1, rigidly with a slider 16, at the same time

The central part of which is equipped with guide posts 2, on which a rectangular traverse 3 is fastened with fixed-shaped levers 18 are installed in a vertical position. When this occurs, the most distant stationary blocks, which are located on it, are engaged. 4. The center of the gripping device

Traverse 3 is connected to auxiliary pipe edges. The movable blocks of 8 remaining winch cables 5 double winch lifting machine. On the guide posts 2, by means of rollers 6 arranged in longitudinal grooves, sliders 7 are installed with 20 fixed in longitudinal grooves fixed by them with movable blocks 8 installed on opposite sides with rectangular frames 9 pivotally connected to eyelets 10, enshrined

with in a vertical position, as fastened in rectangular frames 9, pivotally connected with eyelets 10, fixed on sliders 7, and rollers 5, mounted on sliders 7. Movable blocks 8 and fixed 4 bend around

governing racks 2.

With a further rise of the main winch axis along inclined guides 17 and L-shaped levers 18 along the main

a flexible element 11 of independent control of 25 horizontal slant guides 20 articulated with cables of the main winch.

The sliders 7, which interact in the upper position with the stops 13 mounted on the guide posts 2 on opposite sides and in the lower position with the support lugs 14, are pivotally connected to rigid rods 15 that are also pivotally connected to the sliders 16 mounted in the additional inclined guides 17, located between the sliders 7 and the L-shaped levers 18, with the possibility of reciprocating movement from opposite sides in each section of the frame 1, and additional

Shunt to the center of the gripping device in a vertical position regardless of the position of the sliders 7 and the pipes that are offset from the center of the gripping device are shifted to the center of the device until all the l-shaped levers 18 engage with the pipes from opposite sides.

Thus, the engagement pipes are arranged symmetrically relative to the center of the gripping device, regardless of their length. The lifting and transport of the pipes is done by both lifting mechanisms; when the pipes are lowered onto a vehicle or a pile of rigid rods 19 are rigidly connected to half 40, they are detached from the gripper with fittings 16, the other ends of which are also solids.

pivotally connected to the shoulders of the L-shaped. When lowering the main winch of the half-levers 18 fixed to the axles 20, the takers 7 move along the guides with the possibility of reciprocating 2 to the lower position,

tel movement in the main horizontal-on the main rigid rods 15 and the additional guides 21, located 19, are connected with the L-shaped

opposite sides in each section of the frame 1.

The device works as follows.

In the free state, the gripping device for pipes is connected by cables 5 of the auxiliary winch with cross-member 3. Slides 7 with movable blocks 8 are located in the lower part of the uprights 2 and interact, with supporting lugs 14,

and the L-shaped levers 18 are located at the end of each rigid cable articulated in the horizontal position and project with the short arm corresponding to the frame; 1. In this state, the gripping device is ready for operation.

levers 18, which, simultaneously turning on axles 20, set the gripper to a horizontal position, at the same time freeing all the pipes from engagement.
