Description

one

The invention relates to the reloading technique and can be used for unloading bulk cargo from non-self-propelled vessels to river transport.

A tipper for unloading bulk cargo from non-self-propelled vessels is known, comprising a driving rotor mounted on hinge bearings, a receiving bunker with a conveyor and a ship lift with guides and ship carriages.

However, the known tipper with large drops of water level has limited application, which reduces the performance of unloading operations.

The purpose of the invention is to increase the productivity of unloading operations at significant differences in the water level.

This is achieved by the fact that the rotor consists of several coaxially mounted rings, and the ship-carrying carts are equipped with vertical posts with automatic couplers, which close the rings of the split rotor, with load dividers and stops for securing the ship in the upper part of the rings and .

FIG. 1 shows the proposed tipper, general view; in fig. 2 - rotor, cross section; in fig. 3 - ship cart, cross section; in fig. 4 - tipper in conjunction with a vertical ship lift.

The tipper contains a rotor 1, including 2 split rings 3 installed on roller bearings, a receiving hopper 4 with a conveyor 5, a boat lift 6 with inclined guides 7 and ship carts 8.

In the upper part of the split rings 3 there are mounted triangular dividers 9 of the load stops 10 for securing the vessel, and in the lower part there are guides 11 for the ship carrier body.

Ship trolleys 8 are provided with vertical posts 12, which overlap the notches in the rings 3 of the rotor 1. Automatic couplings 13 and 14 are installed in the upper and lower parts of the ship carrier trolley, and an elastic support 15 is provided for the positioning of the ship.

To fix the rotor in the initial position, a rotation stop 16 and protrusions on the ship carriages 8 are provided.

The actuator for turning the rotor is an electric actuator with a worm gearbox 17. To reduce the friction forces of the pa guideways 7, a force airbag 18 is formed by compressed air. Air is supplied from a stationary compressor through the air manifold 19, control valves

20 and 21 to the working air ducts 22 with ball valves 23.

The tipper works as follows.

The ship lift 6 is brought to its original position so that the ship carriages 8 are pulled out of the rotor 1 and lowered into the water to the necessary depth for approaching the loaded ship. At the same time, the guides of the ship carriages 8 for the inclined ship lift are a continuation of the tracks of the ship lift 7. After that, the towboat leaves the ship elevator 6. A lift mechanism is turned on at the control panel, and the ship bogies 8 begin to lift the vessel out of the water. The vessel rises before its approach together with the ship carriages into the wrecker, while the vertical posts 12 block the cutout in the rings of the rotor 1 and are connected to it by means of automatic couplers 13 and 14. Due to the presence of stops 10, the vessel is rigidly attached to the rotor 1. The lifting mechanism is activated and rotation of the rotor 1, and the cargo from the vessel's hold is poured into the receiving bunker 4, from which conveyor 5 is fed to the coastal warehouses. After unloading the ship rotor

1 is turned in the opposite direction until the protrusion of the ship trolley 8 in the area of the coupler 14 touches the guides 7 of the elevator 6. Then the coupler 13 and 14 are released, the launching mechanism is activated, and the shipboat 8 lowers the vessel back into the water. A tugboat approaches the empty vessel, landing ropes are delivered, and the vessel is taken out of the ship’s elevator. A new loaded vessel is being placed on its place, and the entire unloading cycle is repeated.
