Description

The utility model relates to the timber industry and can be used in coastal warehouses and surfship raids for unloading flat rafting units from the water and launching them.

A device for unloading flat rafting units is known, containing a hoisting frame, additionally equipped with consoles, on which hoisting hooks are fixed with the possibility of placing them at a distance between them equal to the location of the two upper strappings of a single-row flat rafting unit, and also with the possibility of placing them at a distance equal to the length of the formed upper row of a two-row flat rafting unit, while the said hooks are equipped with load-handling slings with choker grips (see Pat. RF No. 2476366, M. cl. , bulletin No. 7).

The disadvantages of this device are the high labor costs for unloading flat raft units from the water and the low productivity of the lifting machine.

The problem to be solved by the utility model is to reduce labor costs for unloading flat raft units from the water and increase the productivity of the lifting machine.

To solve this problem, in a device for gripping flat rafting units, containing a hoisting frame, additionally equipped with consoles, on which hoisting hooks are fixed with hoisting slings installed on them, according to the utility model, on hoisting slings, the length of which is greater than the height of a flat rafting unit, the hooks are suspended two beams.

The beams suspended on the lifting slings are submerged in the water, while the lifting slings, the length of which is greater than the height of the flat raft unit, will be taut, which allows you to get the flat raft unit, which is afloat, between the lifting frame and the beams, and lift it out of the water . This eliminates the need for manual engagement of individual timbers by means of choker grips, as well as the dismantling of flat rafting units on the water, which reduces the time for unloading one flat rafting unit from the water. As a result, labor costs for unloading flat raft units from the water are reduced, and the productivity of the lifting machine is increased.

In FIG. 1 shows a side view of a device for gripping flat raft units;

in fig. 2 is the same, front view.

The device for gripping flat rafting units contains a load-handling frame 1, additionally equipped with consoles 2, on which load-handling hooks 3 are fixed with load-handling slings 4 installed on them. .

A device for gripping flat raft units mounted on a hoisting machine operates as follows.

By means of a hoisting machine, a device for gripping flat rafting units is directed onto a conductive yard with six flat rafting units and lowered into the water so that the beams 6 suspended on the hoisting slings 4 by means of hooks 5 inserted into the lugs 7 are immersed in water to a depth greater than the draft of the flat rafting unit. units, and the load-handling frame 1, additionally equipped with consoles 2, on which the load-handling hooks 3 are fixed, was above the surface of the flat raft unit. The flat rafting unit is inserted between the load-gripping frame 1 and the beams 6, so that the bottom row of round timber of the flat rafting unit is perpendicular to the beams 6. The lifting machine raises the device for gripping flat rafting units, the beams 6 rest against the bottom row of round timber of the flat rafting unit. The flat rafting unit, together with the device for gripping flat rafting units, is removed from the water and moved by a hoisting machine onto specially prepared spacers, the height of which is greater than the thickness of the beams 6, or onto a roller table, between the rollers of which beams 6 can freely fit. Device for gripping flat rafting units together with a rafting unit is lowered by a lifting machine onto specially prepared pads or onto a roller table so that the hoisting frame 1 rests on a flat rafting unit, and the beams 6 rest on the floor (soil) of the platform or the roller table frame, while the hoisting slings 4 are loosened and the hooks 5 are removed from lugs 7. Beams 6 are removed from under the flat raft unit and placed on the floor (soil) of the site. The device for capturing flat raft units by the lifting machine is pointed at the beams 6, the hooks 5 are inserted into the eyes 7 and the device for capturing flat raft units is ready to unload the next flat raft unit.

A device for gripping flat raft units mounted on a lifting machine can be used to launch flat raft units into the water. In this case, the beams 6, previously removed from the load-handling slings 4, are placed under a flat rafting unit installed on gaskets or a roller table perpendicular to the timber of the first row. The lifting machine directs the device for capturing flat rafting units onto a flat rafting unit so that the lifting frame 1 rests on a flat rafting unit, while the lifting slings 4 are loosened and the hooks 5 are inserted into the eyes 7. The device for gripping flat rafting units together with the rafting unit is lifted lifting machine and moves into the water area of the water body, then lowered into the water so that the beams 6, suspended on the lifting slings 4 by means of hooks 5 inserted into the eyes 7, are immersed in water to a depth greater than the draft of a flat rafting unit. The flat raft unit is removed from the device for capturing flat raft units, and this device is lifted out of the water by a lifting machine, the flat raft units are placed on the shore, then lowered to the ground by beams 6 so that the load-handling slings 4 are loosened. The hooks 5 are removed from the eyes 7 and the device for gripping flat raft units is ready to launch the next flat raft unit.

Consoles 2 allow you to install lifting hooks 3 at different distances from each other, depending on the size of the flat rafting units. The lengths of the lifting straps 4 and beams 6 are selected depending on the size of the flat rafting units.

The use of this device for capturing flat raft units will reduce labor costs and increase the productivity of lifting machines when unloading flat raft units from the water. This device can be used for launching flat rafting units into the water and moving them within timber warehouses.

Claims (1)

A device for gripping flat raft units, comprising a load-gripping frame, additionally equipped with consoles, on which load-handling hooks with load-handling slings mounted on them are fixed, characterized in that on the load-handling slings, the length of which is greater than the height of the flat raft unit, two beams are suspended by the hooks.
