Problems solved by technology
However, in this patent, setting tractors on both sides of the bank needs to occupy a certain width of the tunnel, which will greatly increase the construction difficulty and project investment.
In addition, the traction mechanisms on both sides of the bank are fixed. When the water level drops, the component force of the same traction rope pulling force in the direction of the ship's navigation will be smaller, which is not conducive to the installation of traction devices.
In addition, in the actual operation of this patented technology, the traction ropes on both sides need to be thrown to the ship, which also increases the process complexity of the on-site operation

[0043] Specific implementation method: see figure 1 and figure 2 , a non-self-propelled traction device for ships passing through a navigable tunnel, including a tractor track 1 arranged in the tunnel along the length direction of the tunnel and a tractor 2 arranged on the tractor track 1, the tractor 2 is provided with a device capable of driving the tractor The driving device running on the track of the tractor, the tractor is also provided with a traction device, the traction device includes a traction rope 3 for pulling the ship; it also includes a control system, the control system has a central controller connected to the driving device and the traction device 17. The tractor track and the tractor are set in the middle of the tunnel top.
[0044] In this way, when the ship enters the tunnel, the central controller lowers the traction rope from the tractor by controlling the traction device, and the lower end of the traction rope is tied to the ship, and then controls t...

The invention discloses a navigation tunnel ship non-self-propelled passing traction device wich comprises a tractor track which is arranged in a tunnel in the length direction of the tunnel, and a tractor which is arranged on the tractor track; a driving device capable of driving the tractor to travel on the tractor track is arranged on the tractor, a traction device is further arranged on the tractor, and the traction device comprises a traction rope used for dragging a ship; the navigation tunnel ship non-self-propelled passing traction device further comprises a control system which is provided with a central controller connected with the driving device and the traction device, and is characterized in that the tractor track and the tractor are arranged in the middle of the top of the tunnel. The invention further discloses a navigation tunnel ship non-self-propelled passing traction method adopting the navigation tunnel ship non-self-propelled passing traction device. The device has the advantages of being simple in structure, lower in tunnel excavation construction requirement, less in engineering cost, better in ship traction navigation effect, better in safety and high in navigation efficiency.
Description
technical field [0001] The invention relates to the technical field of tunnel ship navigation, in particular to a traction device and method for non-self-propelled passage of a ship in a navigation tunnel. 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, ...
