Problems solved by technology

However, in this patent, the tractor pulls the ship forward to realize navigation, and the ship is easy to swing left and right along the water flow in the river. At the same time, the patent navigation control method is simple, which makes the navigation stability poor and the safety low

specific Embodiment approach

[0061] A method for controlling ship navigation in a two-end traction type tunnel, wherein tractor tracks are arranged along the length direction of the tunnel on both sides of the tunnel or on the top of the tunnel, and tractors are arranged in pairs along the front and rear directions on the tractor tracks. A traction device is provided, and the traction device includes a traction rope for towing the ship. The navigation control process specifically includes the following steps:

[0062] (1) After the bow of the ship enters the tunnel, the ship stops self-propelled, and two traction ropes are released from the tractor in front to connect with both sides of the bow, so that it forms a forward traction on both sides of the bow;

[0063] (2) Control the tractor in front to move forward and release the traction rope, so that the angle between the traction force of the bow of the traction rope and the horizontal direction reaches the set value α1, and the angle between the bow tra...

Abstract

The invention discloses a two-end traction type tunnel ship navigation control method. The method is characterized in that tractor tracks are arranged on shores on two sides of a tunnel or at the topof the tunnel along the length direction of the tunnel; tractors are arranged on the tractor tracks in pairs in the front-back direction; a traction device is arranged on each tractor; the traction device comprises a traction rope used for pulling a ship, in the navigation control process, forward traction force is applied to the ship through a front tractor, backward reverse constraint force is applied to the ship through a rear tractor, and the ship is controlled to pass through an acceleration running section and then run out of a tunnel at a constant speed. The two-end traction type tunnelship navigation control method has the advantages of being better in ship traction navigation effect, better in navigation stability and higher in safety.

Description

technical field [0001] The invention relates to the technical field of tunnel ship navigation, in particular to a method for controlling navigation of tunnel ships with traction at both ends. Background technique [0002] In water transportation projects, in order to realize the navigation of ships in restricted areas, closed waterways are often excavated through mountains, called navigation tunnels. my country's mountainous area accounts for nearly 70% of the country's total land area. In order to further improve the level of mountainous river channels, it is often necessary to design and dig artificial canals. When the artificial canal encounters high mountains and ridges and it is difficult to bypass, it is necessary to excavate tunnels through the high mountains and ridges for navigation. The axis of the hydraulic tunnel is generally a straight line, and the water depth, width and navigation clearance of the tunnel should meet the navigation requirements, and are usuall...
