Description

The invention relates to handling equipment used in the mining industry and the production of building materials. It is used for the transfer of bulk materials, such as sand, sand and gravel or crushed stone, from pneumatic to water transport.

A device for loading ships with bulk materials is known, including an arrow mounted on a gantry crane with the possibility of lifting and lowering. The boom carries a conveyor belt, which is loaded using a feed conveyor belt and an unloading drum, and unloaded through a gravity trolley [1].

The disadvantages of this device are high capital costs, significant operating costs due to additional transshipment operations and increased energy intensity of loading operations.

A device for loading bulk cargo into the holds of a vessel [2], containing a flyover with a pavement placed along the mooring wall on the columns, a loading chute, movably mounted on the flyover, with the ability to move along the flyover along the entire length of the loading front.

The disadvantages of the device are significant capital costs, low productivity of the device, increased danger of work.

The closest in technical essence is a device for loading bulk cargo into the hold of a vessel [3], containing a flyover with a pavement placed along the mooring wall on the columns, a loading chute movably mounted on the trolley, with the possibility of sequential movement along rails under the overpass along the loading front . With the help of this device, bulk material is received from the pneumatic wheeled transport to the loading chute, the loading chute is moved through kinematic connections with power cylinders that rotate the loading chute in the vertical plane and the bulk material is loaded into the vessel’s hold, and the truck is periodically moved by rail with the loading chute along the rails the entire length of the loading front, equal to the total length of the holds of the vessel.

The disadvantages of this device are high capital costs, a complex control system for the movement of the trolley along the front of the ship, the low productivity of the device and the increased risk of work.

The technical result consists in increasing the productivity of the process of loading bulk materials by automating the management of the loading and reloading process through two gutters, increasing the safety of work, reducing capital costs and increasing reliability.

The technical result is achieved by the fact that in the method of loading bulk materials into the holds of a vessel, which includes receiving bulk material from a pneumatic wheel onto a loading chute, moving the loading chute by means of kinematic connections with power cylinders, ensuring the rotation of the loading chute in a vertical plane and loading the bulk material into the ship's hold , periodic movement by means of a trolley drive with a loading chute along the rails over the entire length of the loading front equal to the total length of the holds on, by supplying the moving trolley with an additional loading chute and kinematic connections of both loading chutes with power cylinders through L-shaped levers, simultaneous processes of receiving bulk materials, their loading into the hold of the vessel and periodic movement of the trolley by means of a drive made in the form of an autonomous power plant located on the trolley, while automatically synchronizing the operation of the power cylinders mounted on the trolley through the control unit and sludge cylinders mounted on the loading chutes, to exclude spillage of bulk materials, while the loading chutes are made in the form of a container equal to the capacity of pneumowheel transport, with a V-shaped bottom.

The possibility of forming the required sequence of actions by the proposed means allows us to solve the problem, determines the novelty, industrial applicability and inventive step of development.

The complex for implementing the method of loading bulk materials into the holds of a vessel is shown in the drawings.

In FIG. 1 is a general view of the complex in the process of receiving bulk material from a pneumatic wheel transport at one of the loading troughs and simultaneously pouring bulk material from the other loading trough into the holds of the vessel; in FIG. 2 is a plan view of FIG. one.

Complex 1 includes a trolley 2, on which loading chutes 3, 4 are installed for receiving and pouring bulk material from a pneumatic-wheeled transport 5 into the holds of a vessel 6. Both loading chutes 3, 4 are connected to power cylinders through kinematic links with L-shaped levers 7, 8 9, 10. The movement of the loading chutes 3, 4 ensures their rotation in the vertical plane 11. The trolley 2 is periodically moved by means of a drive 12 made in the form of an autonomous power unit located on the trolley 2. The control unit 13 It provides synchronization of the operation of the power cylinders 9, 10 to prevent spillage of bulk material. The loading chutes 3, 4 are made in the form of a container 14, equal to the capacity of the pneumatic-wheeled transport 5, with a V-shaped bottom 15. The trolley 2 is mounted on rails 16 over the entire length of the loading front 17.

The method of loading bulk materials into the holds of a vessel is implemented as follows.

One of the loading troughs 3 of complex 1 of the bulk material is received from the pneumatic wheel transport 5. Since the loading chutes 3, 4 with a V-shaped bottom 15 are made in the form of a container 14 equal to the capacity of the pneumatic wheel transport 5, high productivity and safety of work are ensured. Then, rotation in the vertical plane 11 of the loading chute 3 is carried out using L-shaped levers 7 by means of kinematic connections with the power cylinders 9, 10 and loading of bulk material into the hold of the vessel 6. Automatically through the control unit 13, the operation of the power cylinders 9 mounted on the trolley is synchronized 2, and power cylinders 10 mounted on the loading chutes 3, 4 to align the angle of inclination of the V-shaped bottom 15, which is moved in space to prevent spillage of bulk materials. Providing the moving trolley 2 with an additional loading chute 4 and kinematic connections of both loading chutes 3, 4 with power cylinders 9, 10 through the L-shaped levers 7, 8, simultaneously taking place the processes of receiving bulk materials, loading them into the hold of the vessel 6 and periodic movement of the carriage 2 by means of a drive 12 made in the form of an autonomous power plant located on a trolley 2, which moves along rails 16 over the entire length of the loading front 17, equal to the total length of the holds of the vessel 6.

The method improves the performance of loading bulk materials by automating the control of the loading and reloading process through two gutters, and also increases the safety of work, reduces capital costs and increases reliability.
