Description

one

The invention relates to the field of mechanization and automatization of logistic and unloading and assembly work and can be used in sea and river ports and other public enterprises that overload or install large diameter pipes.

An automatic pipe grip is known, consisting of an arcuate neck and the arc length of which is 180 °, and a pressure cheek pivotally connected to it. Both cheeks together grab the pipe in an arc greater than 180 °. In the other, at the end, the presser cheek is hingedly connected to a lifting lever, guided to the crane hook by means of a bracket. The pressing cheek is strengthened in relation to the arcuate cheek with the help of the knee-shaped shaft, installed in the corresponding hole of the arcuate cheek. When turning the shaft, his knee pushes or pushes the presser cheek out of the arcuate cheek, adjusting the angle obx: the cotton wool of the pipe.

In order to hold the cheeks in the open position, the grip is placed on the pipe, a special lock with a dog mounted on one shoulder of the pressure cheek is attached. The dog grasps the protrusion located on the arcuate cheek to hold the grip in the open position.

For removal of the dog, a solenoid is attached, which is installed on the pressure cheek. The core of the solenold is connected to the dog. When this grip is applied to the pipe, the lock is opened with a solenoid. When lifting the gripper clamp cheek pipe. When the pipe is hollowed out with olora, the thinner on the cheek releases the pipe. Under the influence of the force of the body, the dog engages with the protrusion on the arcuate cheek, the car locks the cheeks in the open position 1.

This capture cannot be used to capture nl of medium or extreme tubes laid in dense rows in a stack or in the hold of a vessel.

Also known is a grip for pipes containing arcuate iododerzhivayuyu and LIrizhny cheeks, pivotally interconnected, and the mechanism of fixing the mutual laid 1 NIS 2.

This grip provides the ability to grip an extremely 1x pipe) 1z stack, but it can be used only on cranes with a single-drum winch that requires a large amount of manipulation by the boom of the crane.

The aim of the invention is to extend the functionality of a gripping device by providing a gripping of pipes from a stack using a lifting mechanism equipped with a double-drum winch with supporting and pull-up cables.

This is achieved by the fact that the grip is equipped with a traverse with earrings at the ends intended to be connected to the supporting catnama, one end of the traverse is pivotally and the other is connected to the supporting cheek by a flexible link, and the pressing cheek is made in the form of a two-armed lever, and The mechanism of fixation includes an axis fixed at the end of the pivot lever and a figure skull, made in the traverse, and a block is installed on the axis for storing the closing rope.

The drawing shows the proposed capture, the overall appearance.

The grip contains an arcuate / and two cheeks 2 cheeks connected by a charpyr 3. The cheeks are equipped with hold-down shoes, 4 kami, one of which clamps the pipe to the left of the lower quarter of the circumference and the other to the top of the grass. Attached to the cheek / sharnpr 5, axis 6 and flexible connection, made in .3 form of step 7, is attached to the yoke 8, which has a figured notch in the middle of the lower part, forming tooth 9 and a shaped groove JO. Traverse 8 with the help of cargo eherg suspended from the supporting ropes // cargo winch edge. The cheek 2 at the upper end is provided with a block 12, which is applied to the elongated axis 13, which interacts with the tooth 9 of the traverse. Block 12 is suspended from the locking ropes 14 of the cargo winch.

Capture works as follows.

In the open view, the grip is held on by the weight of the ropes. The ropes M are loosened, block 12 is below the traverse, and its axis 13 is outside the groove 10. Chain 7 is outs. In this type of grip, a pipe is placed on the extreme one in the stack, and it is supplied from the side free from pipes. The ropes // are loosened and the ropes 14 are lifted. Lift up, the axis 13 of the block 12 rests with its ends into the traverse 8 from below and lifts it. In this case, the extended axis slides along the traverse in the direction of the hinge 5 and enters the groove 10 formed by the tooth 9. The lifting of the closing ropes is performed until the pipe is clamped between the shoe 11 and the cable 11 and the pipe lifted by all four ropes. The foot 7 is slightly weakened at this time, as it does not carry the pipe, but

serves only to lift the open grip. In the raised view, the grip holds the tube securely. Accidental loosening of locking or supporting ropes

does not entail disclosed capture. So, if the supporting ropes are accidentally weakened, then the opening is not taking place, since the moment of force of the weight of the pipe and the arcuate around the hinge 3 is reliably

closes the grip. When loosening the connecting ropes, the opening of the grip also does not penetrate, since the tooth 9, the crosshead 8, holding the axis 13, ensures a reliable closing of the grip. Pipe release

It can only be taken from the grab if the pipe is laid on the base and all four ropes are loosened. In this case, the yoke 8 rotates around the hinge; i 5, with the result that the axis 13 of the block

12 goes out of the groove 10. To remove the grip from, it is necessary to pull the ropes //, leaving the ropes 14 weakened.

The invention will automate the reloading of large-diameter pipes from ships to piles on the shore and vice versa.

F o rm} l and inventions

An automatic gripper for tr} b, containing arcuate supporting and tightening cheeks that are jointly connected between each other, and a mechanism for fixing the mutual position of the cheeks, characterized in that, in order to expand its functional capabilities by providing a gripping of pipes from a stack with the aid of a lifting mechanism, equipped with a two-bar bath winch with supporting and closing ropes, it is equipped with a cross-bar with cepbraiMH at the ends to be connected to the supporting ropes, one end of the cross-bar is hinged, and the other By means of a flexible connection, it is connected to the supporting cheek, and

L.RIZHI, the cheek piece is made in the form of a two-arm lever, with this the fixation mechanism includes an axis fixed at the end of the pressure lever, a figured groove made in the traverse, and a small rope is installed on the smallpox.
