Description

Technical Field

[0001] The present invention relates to the field of ship cabin shed rack devices, and more specifically, to an automatic shed rack device for inland river bulk carriers. Background Art

[0002] Inland waterway shipping plays an indispensable role in my country's modern transportation system. Compared with railway and road transportation, it has the advantages of large transportation volume, low freight, low construction cost, and environmental friendliness. Shipping waterways such as the Yangtze River and the Pearl River are the main transportation arteries connecting my country's coastal and inland areas. A large number of goods are transported to cargo distribution centers by inland ships, which greatly promotes regional economic development. my country's inland waterway shipping is well developed. As of 2023, the number of inland waterway transport ships in my country will reach 115,000. The types of inland waterway ships include passenger ships, passenger and cargo ships, general cargo ships, container ships, bulk carriers, and oil tankers. Since inland waterway shipping is particularly suitable for bulk dry bulk goods such as coal, grains, ore, sand and gravel that do not require high timeliness, bulk carriers account for more than 85% of the total number of inland waterway transport ships. The cost of ships is much lower than that of seagoing ships. The cost of a 5,000-ton inland bulk carrier is usually no more than 20 million yuan.

[0003] Inland waterway shipping mostly uses bulk carriers to transport bulk commodities. When inland bulk carriers transport bulk commodities, they usually use flexible rainproof cloth or steel hatch covers to cover the transported goods. If gravel, ore, etc. are transported, they are directly exposed or covered with flexible rainproof cloth; if grains, etc. are transported, they are covered with steel covers. Flexible rainproof cloth has poor protection effect and is not beautiful. Especially when transporting gravel, coal and other goods, it is easy to cause dust and other environmental hazards. The steel cover is heavy and complicated and inconvenient to operate, which brings great inconvenience to the transportation of cargo by inland waterway ships. Therefore, the existing cabin covering methods cannot meet the requirements of high-quality development of inland waterway shipping. Therefore, it is urgent to develop an automated shed cloth rack device suitable for cabin covering of inland bulk carriers. Summary of the invention

Two adjacent shed cloths are overlapped at the support structure and are located between the lower reinforcing steel plate and the upper reinforcing steel plate. The two adjacent shed cloths are connected between the lower reinforcing steel plate and the upper reinforcing steel plate by a plurality of bolts to form a whole.

[0030] The support structure is assembled from three galvanized steel pipes, with supporting connecting rods 71 ​​set at a certain distance, and diagonal rods 72 connected between adjacent connecting rods to enhance the rigidity of the support. The cross section of the support is arranged in an equilateral triangle, and a lifting ring 8 is set at the node position of the connecting rod 71, and the upper part of the lifting ring is connected to the hanger 17. The two adjacent awning cloths are partially reinforced at the support, and are reinforced by adding reinforced steel plates with a width of 10cm and a thickness of 2mm up and down, and bolts 16 are set to connect the two awning cloths into a whole. A hanger 17 is set at the lower part of the lower reinforced steel plate, and the lifting ring 8 is connected to the hanger 17 to connect the awning cloth 15 to the support 7. Multiple groups of supports and awning cloths are connected in sequence to form a whole rigid and flexible covering system, which can move along the length of the ship with the slider base, thereby realizing the opening and closing of the awning cloth frame.

[0031] In another technical solution, a front winch is provided at the front of the hatch opening, and a rear winch is provided at the rear of the hatch opening. A plurality of support units are driven by winches provided at the front and rear ends to drive the shed cloth structure to move along the length direction of the cabin, thereby realizing the opening and closing of the shed cloth rack device.

By tightening the cable, each electric pin is physically judged to be at the corresponding pin hole position. Position sensors can also be set at the electric pin positions corresponding to the bracket structures on both sides to assist in judging the corresponding pin hole positions of each electric pin. As long as the electric pins corresponding to the bracket structures on both sides are at the corresponding pin hole positions, the corresponding electric pins on the remaining bracket structures are also at the corresponding pin hole positions, so that the slider base and the shed cloth rack device on the upper bracket are moved into place and the corresponding electric pins are activated, and the electric pins can be inserted and ejected to achieve the fixation of the slider base. In addition, the setting of the cable length can also limit the maximum distance of movement of the slider base, while avoiding the shed cloth between adjacent brackets from being subjected to tension due to movement exceeding the maximum distance.

Signal transmission and power supply and control are carried out through the cable 19. The control can be manually controlled by remote control to drive the motor to rotate. When the pin block 91 is in the pop-up state, the boss 93 is in a horizontal state. When the inland ship is loaded and the cabin needs to be covered, the slider base moves to the target position. At this time, the start signal is transmitted to the motor 92 through the cable 19. The motor 92 rotates 90° clockwise, and the boss 93 lifts the pin block 91. The pin block 91 is inserted into the pin hole of the slider base to achieve the purpose of fixing the slider base and its upper structure.

[0039] The tarpaulin rack device of the present application can be opened and closed automatically. The device of the present application includes a wheel-rail system, a slider base, a bracket structure, and a tarpaulin structure from bottom to top.

After the unloaded ship docks, the front winch works, the rear winch is released freely, the electric pin pops out, and the slider base together with its upper support structure and tarpaulin structure moves towards the front winch until all tarpaulin structures are reduced to a minimum, and the cabin of the inland bulk carrier is opened for cargo loading operations; after the cargo loading is completed, the front winch is released freely, and the rear winch works, pulling the slider base and its upper support structure and tarpaulin structure close to the rear winch to drive other slider bases to move toward the rear winch, and the adjacent slider bases move to the corresponding electric pin position. At this time, the cable is in a tensioned state, and the electric pin is inserted into the pin hole to fix the slider base, so that the entire cabin is completely covered and protected. Fixed state.

10. The automatic racking device for inland bulk carriers according to claim 7, characterized in that: The electric pin includes a shell and a pin block, a motor and a boss arranged in the shell. The shell is fixed to the vertical plates on both sides of the cabin port. The top of the shell is provided with a concave groove, in which the pin block is fitted. A boss is fixedly provided on the rotating wheel of the motor and is located directly below the pin block. The boss is driven by the motor to rotate and form a horizontal or vertical state to drive the pin block to pop out of the pin hole and insert into the pin hole.
