Description

This invention relates to lifting and handling equipment, in particular, to load handling devices.

The purpose of the invention is to improve ease of operation.

Fig, 1 shows a load gripping device in the open position; figure 2 - lifting device at the time of lifting.

The load gripping device consists of a frame 1 and a traverse 2, connected by means of a fixation mechanism 3, which can be automatically operated with a four-stroke type with a finger 4. In addition, the device includes a bracket 5 for attachment to the lifting member of the gripping bodies b with levers 7 connected to the bracket 5 articulated arms 8. On frame 1, levers 7 and articulated arms 8, folding closed soft shells 9-11 are secured / By means of slings 12, sheaths are connected by a hose 13 to a source of compressed air. The rod 14 serves to supply a hydraulic fluid to the nozzles 15 located at the ends of the gripping bodies 6.

The device works as follows.

Using known means, the coordinates of the sunken device are determined and the lifting device is lowered onto it in the open position. When landing, the weight of the frame 1 of the yoke 2 is lowered onto the course of the locking mechanism of the automatic fourfold action, which separates the frame 1 and the yoke 2. A hose 13 is attached to the load handling device and is connected to all shells 9-11.

Air is supplied through the hose 13, the anchors 9-11 are broken and the shells are uniformly filled with air and expanded. In this case, the sheath 9 expands the frame 1 and the traverse 2 as it expands, squeezing the load even more. The blowing fluid acts uniformly on all sides of the fluid and they can be performed lightly, since the air pressure is compensated by the pressure of the fluid.

Gripping bodies 6 are equipped with nozzles.

15, to which water is pumped through the hose 14 under pressure, which erodes sludge around the cargo, lowering the gripping bodies b until the load is grasped.

When shells volume 9-11 surpasses

the volume of the sunken cargo, the latter will begin to emerge. As the load floats up, the pressure in the shells 9-11 decreases, preventing the difference in the pressure of water on the surface and the air inside.

After the cargo is brought closer to the surface, it is towed to a specified place. Shells 9-11 can be fitted with air pressure sensors that automatically level it with water pressure.

Claims (1)

Claims The load-carrying device comprising a frame, gripping bodies hinged on it, lower arms connected to them, hinged rods fixed to the upper ends of arms, traverse connected to free ends of grating g, fixing the position of gripping bodies and locking arms framed tanks with varying volumes, which are characterized by the fact that, in order to increase ease of operation, the tanks are made in the form of closed soft shells, their connection with the frame consists of slings, some ends of which are fixed on the shells, and others frame, while the device is equipped with additional soft shells connected together with the main shell with a common source compressed air, additional straps, one ends of which are fixed on the respective additional shells, and others, respectively, on the traverse and levers. /five figl
