The invention relates to lifting and handling equipment, namely to gripping devices.

The purpose of the invention is to improve the performance of the device by increasing its speed.

The drawing shows a gripping device, a general view.

The gripping device contains a frame II, on which the hinges 2 secure the gripping levers 3, 4 connected to the hinges, 5 traverses 6, the rod 7 with the limiters 8, the suspension 9 and the hook 10 with the upper skirt 11 and the outer beveled surface 12, vertical stops 13, included in guides 14, with springs 15 and limited in movement by a pin 16, included in a longitudinal groove 17. One of the stops 13 is equipped with a spring 18 mounted on a double-arm lever 19, mounted on a hinge 20 and fitted with hook 21, interacting with the frame 22 having the upper the crossbar 23, the bracket 24 and the crossbar 25, the frame 22 being fixed on the hinge 26 and retracted by the spring 27 up to the stop 28, and in the cross bar 6 an opening 29 is made through which the bar 7 is passed.

The device works as follows.

The device is suspended without load.

Suspension 9 is attached to the hook of the lifting mechanism. The rod 7 by the upper bevel 11 of the hook 10 is fixed to the upper crossbar 23 of the frame 22. Since the frame 22 by the hinge 26 is fixed on the wound 1, the whole device is suspended,

the cell 25 turns the frame 22 towards the two shoulders lever 19. At the same time, one of the stops 13 rises up and rotates the double-arm lever 19, which hooks the hook 24 with hook 21. As a result, the gripping levers 3 release and lift the weight 7. 1 il.

which is transported to the load being lifted. In this case, the frame 22 with the spring 27 will be pressed against the stop 28, the stops 13 under the action of the springs 15 extend from the guides 14 to the lower position and are held there by pins 16. The spring 18, lowering along with the stops 13, sweat is not the double-shouldered lever 19, which Turning on the hinge 20 will move the hook 21 to the up position. Traverse 6, under the action of the mass, lowers the connecting rods 4, turning on the hinges 5, swiveling 2 gripping levers 3 in them. open position.

To install the device on a load with a lifting mechanism, it is placed, for example, on a barrel or on a metal coil with a cable. The first contact with the load is the stops 13, which, under the action of the mass of the device, will compress the springs 15 and move upwards along the guides 14 to stopping the pin 16 into the longitudinal groove 17. The spring 18, acting on the double-shouldered ridge 19, will turn it on the hinge 20 to the lower position of the hook 21. The rod 7, lowering relative to the fixed frame 1, will press the crossbar 25 of the hook 10, turn va frame 22 on a hinge 26 and a spring 27 to stretch.

Turning camp, frame 22 bracket 25. squeezes out the hook 21 of the two shoulders lever 19, which will compress the spring 18 and, having passed the crossbar, will fix the frame 22 in the position in which the hook 10, lifted by the rod 7, will pass without hitting the upper crossbar 23 of the frame 22.

Lift, the boom 7 will lift the yoke 6 with the stopper 8, which through the hinges 5 tons 4 and swivels 2 gripping levers 3 into the working position, at which the load will be caught by its protruding parts, such as shoulders or flanges. In this case, frame 1 does not raise some distance above the load and the spring, 15, by pressing the stops 13, moves them down relative to the frame 1. Spring 18 will turn the double-arm lever 19 on the hinge 20, hook 21 will release the middle bracket 24 and the frame

22 under the action of the spring 27 will turn-15 of the lifting mechanism at the upper end of the hinge 26 to the initial position up to the stop 28.

In this position, the device will move and handle the cargo, and by delivering it to its place. 20

An element connected to the frame interacting with the rod, characterized in that, in order to improve the performance characteristics by increasing its speed, it is equipped with a double-arm lever with a hook on one of its shoulders located in the lower part of the frame spring-loaded in the upper part of the frame stops with their stroke limiters, one of which is connected to the other arm of the two shoulders, and the rod engagement element is a spring-loaded spring mounted on the axles from the ends of the frame A frame with a crossbar and a bracket for interacting with the hook of the two shoulders lever, while the yoke is made with a vertical hole for the rod, at the lower end of which the hook is fixed, facing to the two shoulders with the hook, and having a beveled outer surface for interacting with the crossbar frames and vertical movement limiter.

To release the device, a load-carrying mechanism with a suspended load is lowered to the place of overload. When lowering the load on a rigid base, the load from its mass is removed from the device, frame 1 is lowered onto the surface of the load. Rod-7, continuing slow lowering, moves the yoke 6 downwards relative to the frame 1 and rotates the gripping levers on the hinges 5 tons 4 3, discharging them to the side of the cargo. The rod 7, continuing to slowly move, the outer beveled surface 12 pushes the upper crossbar 23 and the frame 22 under the action of the spring 27 snaps on the upper bevel 11 of the hook 10.
