Description

Technical Field

[0001] This invention relates to the field of inland waterway navigation technology, and in particular to a ship traction device and ship traction process for a shipping tunnel. Background Technology

[0002] Currently, in the overall design of navigation tunnels, when using towing navigation, mechanical traction via wire rope traction devices is typically employed to facilitate vessel passage. The traction rope is led out from the front drum of the drive unit, passes through a guide wheel mechanism, and connects to one end of the towing device. The traction rope is simultaneously connected to the other end of the towing device and then returned to the rear drum of the drive unit via the guide wheel mechanism. The drive unit uses a motor and transmission mechanism to rotate the front and rear drums in the same direction. The traction force is applied by the friction between the rope groove and the traction rope. One drum releases the rope while the other retracts it, allowing the towing device, positioned on the tunnel surface, to move forward and backward along the track following the traction rope. The movement of the towing device relies entirely on the traction force transmitted by the traction rope. The traction device is connected to the towed vessel via a tugboat cable, and the towing device moves the towed vessel through the tow hook and tugboat cable, completing the towing operation. However, the mechanical traction of wire rope tractors is typically used in straight sections of navigation tunnels or locks, where there are no curved sections. Therefore, when this type of tractor is used in medium- to long-distance curved navigation tunnels, it suffers from poor practicality, a high risk factor when ships navigate on their own in the tunnel, and unreliable safe operation of tracted ships in navigation tunnels. Summary of the Invention

[0003] The purpose of this invention is to provide a ship traction device and ship traction process for navigation tunnels, so as to alleviate the problems of poor practicality, high risk factor when ships navigate on their own in medium and long distances of curved navigation tunnels, and unreliable safe operation of traction ships in navigation tunnels when existing ship traction devices are used.

[0004] To solve the above-mentioned technical problems, the technical solution provided by the present invention is as follows:

[0005] The shipping tunnel vessel traction device provided by the present invention is applied to medium and long-distance curved navigation tunnels and includes: multiple traction vehicles, each traction vehicle including a locomotive body, a self-retracting traction rope assembly and a sensing control assembly;

[0006] Both banks of the medium-to-long-distance curved navigation tunnel are equipped with train tracks. The self-retracting traction rope assembly and the induction control assembly are both installed on the locomotive body. The induction control assembly is connected to the self-retracting traction rope assembly by signal. Multiple tractors are slidably installed on the train tracks and connected to the ships waiting to pass through the tunnel.

[0007] As a further technical solution, the sensing control component includes a direction sensor, a distance sensor, and a controller. Both the direction sensor and the distance sensor are connected to the controller via signals. The controller controls the usage status of the self-retracting traction rope component based on the received signals.

[0008] As a further technical solution, the tractor also includes at least one set of balance guidance mechanism and two rows of locomotive wheels;

[0009] Two rows of locomotive wheels are set parallel to each other on the bottom wall of the locomotive body, and the balance guide mechanism is set on the bottom wall of the locomotive body corresponding to the locomotive wheels.

[0010] As a further technical solution, the balance guide mechanism includes two horizontal guide components, which are arranged in parallel and spaced apart on both sides of the corresponding locomotive wheel.

[0011] As a further technical solution, the horizontal guide assembly includes a guide bracket and a horizontal guide wheel. The first end of the guide bracket is fixedly set on the bottom wall of the locomotive body, and the second end of the guide bracket extends in a direction away from the locomotive body. The length of the guide bracket is greater than the diameter of the locomotive wheel. The horizontal guide wheel is rotatably connected to the second end of the guide bracket. The axis of the horizontal guide wheel is set at an angle with the guide bracket, and the horizontal guide wheel rolls in cooperation with the corresponding track.

[0012] As a further technical solution, the balancing guide mechanism also includes two guide components, which are respectively set on two horizontal guide components and cooperate with the corresponding travel rails.

[0013] As a further technical solution, the guide assembly includes a guide wheel, which is rotatably connected to the second end of the guide bracket. The axis of the guide wheel is set at an angle to the guide bracket, and the guide wheel slides in cooperation with the corresponding travel track.

[0014] As a further technical solution, the tractor is equipped with an electric drive mechanism, and the shipping tunnel ship traction device also includes multiple power supply mechanisms to supply power to the electric drive mechanism.

[0015] As a further technical solution, the ship traction device in the shipping tunnel also includes a maintenance mechanism, which is set up in a medium-to-long-distance curved navigation tunnel and connected to the trolley track. The maintenance mechanism includes a lifting and maintenance component for replacing a single tractor.

[0016] The ship traction process provided by this invention, which utilizes a ship traction device for shipping tunnels, includes the following steps:

[0017] Multiple tractor units are divided into two groups. The two groups of tractor units are respectively set on the running tracks on both sides of the medium- and long-distance curved navigation tunnel, and the side of the tractor unit equipped with the balance guide mechanism is set away from the center of the medium- and long-distance curved navigation tunnel.

[0018] The first group of vessels arrived at the hooking area, and the tractor at the front of the first group of vessels hooked up the first vessel in the first group that was about to pass through the tunnel.

[0019] The tractor on the left bank hooked up with the starboard side of the bow of the first vessel waiting to pass through the tunnel, while the tractor on the right bank hooked up with the port side of the bow of the first vessel waiting to pass through the tunnel.

[0020] The first vessel in the first group of vessels to be transported through the tunnel and the second vessel in the first group of vessels to be transported through the tunnel were located.

[0021] The starboard side of the stern of the first vessel to pass through the tunnel is connected to the starboard side of the bow of the second vessel to pass through the tunnel by a tow rope. The port side of the stern of the first vessel to pass through the tunnel is connected to the port side of the bow of the second vessel to pass through the tunnel by a tow rope.

[0022] The tractor located at the rear of the second group of vessels hooked up with the second vessel in the first group of vessels waiting to pass through the tunnel.

[0023] The tractor on the left bank hooked up with the starboard side of the stern of the second vessel waiting to pass through the tunnel, while the tractor on the right bank hooked up with the port side of the stern of the second vessel waiting to pass through the tunnel.

[0024] The first group of vessels entered the medium-to-long-distance curved navigation tunnel, and the second group of vessels arrived at the hooking area, repeating the above hooking and positioning steps.

[0025] After multiple groups of vessels exit the medium-to-long-distance curved navigation tunnel, they detach from their corresponding tractors. The tractors then enter the charging area, where they are charged by the power supply unit before re-entering the hook-up area to wait.

[0026] Compared with existing technologies, the ship traction device and ship traction process for shipping tunnels provided by this invention have the following technical advantages:

[0027] The shipping tunnel vessel traction device provided by this invention is applied to medium-to-long-distance curved navigation tunnels. It includes multiple traction vehicles, each comprising a locomotive body, a self-retracting traction rope assembly, and a sensing control assembly. Tracks are provided on both banks of the medium-to-long-distance curved navigation tunnel. The self-retracting traction rope assembly and the sensing control assembly are both mounted on the locomotive body, and the sensing control assembly is signal-connected to the self-retracting traction rope assembly. The multiple traction vehicles are slidably mounted on the track and connected to vessels waiting to pass through the tunnel. When tractioning a vessel to pass through the medium-to-long-distance curved navigation tunnel, the traction vehicle connects to the corresponding vessel, providing traction force to the vessel, thereby tractioning it through the medium-to-long-distance curved navigation tunnel. Because the sensing and control components installed on the locomotive body are connected to the self-retracting traction rope assembly, when the tractor moves on the track, if the sensing and control components sense a change in the direction of the track, or if they sense that the distance between the vessel waiting to pass through the tunnel and the side wall of the medium-to-long-distance curved navigation tunnel is too large or too small, the sensing and control components will control the working state of the self-retracting traction rope assembly. This ensures that the forward direction of the vessel waiting to pass through the tunnel can be adjusted according to the direction of the medium-to-long-distance curved navigation tunnel, while ensuring that the vessel always remains in the middle position of the medium-to-long-distance curved navigation tunnel, avoiding collisions and scrapes with the side wall of the medium-to-long-distance curved navigation tunnel. This ensures the safety of the vessel when it navigates independently in the medium-to-long-distance curved navigation tunnel and reduces the risk factor during independent navigation.

[0040] The following detailed description of some embodiments of the present invention is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features described herein can be combined with each other.

[0041] The shipping tunnel vessel traction device provided in this embodiment is applied to medium- and long-distance curved navigation tunnels and includes: multiple traction vehicles 100, each traction vehicle 100 including a locomotive body 110, a self-retracting traction rope assembly 120 and a sensing control assembly;

[0042] Both banks of the medium-to-long-distance curved navigation tunnel are equipped with a track 200. The self-retracting traction rope assembly 120 and the induction control assembly are both installed on the locomotive body 110. The induction control assembly is signal-connected to the self-retracting traction rope assembly 120. Multiple tractor vehicles 100 are slidably installed on the track 200 and connected to the vessel 300 waiting to pass through the tunnel.

[0043] Specific combination Figures 1 to 4As shown, when towing the vessel 300 to pass through the tunnel to pass through the medium-to-long-distance curved navigation tunnel, the tractor 100 connects with the corresponding vessel 300 to provide traction to the vessel 300, thereby towing the vessel 300 to pass through the medium-to-long-distance curved navigation tunnel. Because the sensing control component installed on the locomotive body 110 is connected to the self-retracting traction rope assembly 120, when the tractor 100 moves on the track 200, if the sensing control component senses a change in the direction of the track 200, or senses that the distance between the vessel 300 waiting to pass through the tunnel and the side wall of the medium-to-long-distance curved navigation tunnel is too large or too small, the sensing control component controls the working state of the self-retracting traction rope assembly 120. For example, when the tunnel curves to the left, the traction rope on the self-retracting traction rope assembly 120 on the right bank is extended, and the traction rope on the self-retracting traction rope assembly 120 on the left bank is shortened, thereby controlling the vessel 300 waiting to pass through the tunnel to move forward to the left; or when the distance between the vessel 300 waiting to pass through the tunnel and the left bank of the tunnel is too small, the traction rope on the self-retracting traction rope assembly 120 on the right bank is shortened, thereby pulling the vessel 300 waiting to pass through the tunnel to the right bank, so that the vessel 300 is positioned in the middle of the tunnel for traction navigation. The various components work together to ensure that the forward direction of the vessel 300 waiting to pass through the tunnel can be adjusted according to the direction of the medium-to-long-distance curved navigation tunnel. At the same time, it ensures that the vessel 300 always stays in the middle of the medium-to-long-distance curved navigation tunnel, avoiding collisions and scrapes with the side walls of the medium-to-long-distance curved navigation tunnel. This ensures the safety of the vessel 300 when it is self-navigating in the medium-to-long-distance curved navigation tunnel and reduces the risk factor when self-navigating.

[0044] In the optional technical solution of this embodiment, the sensing control component includes a direction sensor, a distance sensor and a controller. Both the direction sensor and the distance sensor are signal connected to the controller, and the controller controls the usage status of the self-retracting traction rope assembly 120 according to the received signals.

[0045] Specifically, the direction sensor is used to sense the direction of medium-to-long-distance curved navigation tunnels. For example, when the direction sensor detects a leftward bend in front of the tunnel, it transmits a signal to the controller. The controller then controls the extension of the tow rope on the self-retractable tow rope assembly 120 located on the right bank and the shortening of the tow rope on the self-retractable tow rope assembly 120 located on the left bank, thereby controlling the vessel 300 to proceed forward to the left. The distance sensor is used to sense the distance between the vessel 300 and the two banks of the tunnel. For example, when the distance sensor detects that the distance between the vessel 300 and the left bank of the tunnel is too small, it transmits a signal to the controller. The controller then controls the shortening of the tow rope on the self-retractable tow rope assembly 120 located on the right bank, thereby pulling the vessel 300 closer to the right bank and positioning it in the middle of the tunnel for traction.

[0046] In the optional technical solutions of this embodiment, the tractor 100 also includes at least one set of balance guidance mechanism and two rows of locomotive wheels 140;

[0047] Two rows of locomotive wheels 140 are arranged parallel to each other on the bottom wall of the locomotive body 110, and the balance guide mechanism is arranged on the bottom wall of the locomotive body 110 corresponding to the locomotive wheels 140.

[0048] Specific combination Figure 1 and Figure 2 As shown, in this embodiment, two tracks 200 are provided on one side of the long-distance curved navigation tunnel. Corresponding to the two tracks 200 on the same side, two rows of locomotive wheels 140 are provided on the bottom wall of the locomotive body 110. These two rows of locomotive wheels 140 cooperate with the corresponding tracks 200 to ensure the smooth operation of the tractor 100 within the long-distance curved navigation tunnel, thereby ensuring the traction effect on the vessel 300 to be transported through the tunnel. A balancing guide mechanism is provided on the bottom wall of the locomotive body 110 corresponding to the locomotive wheels 140. One set of the balancing guide mechanism is provided, and when the locomotive is located on the track 200, the balancing guide mechanism is positioned away from the axis of the long-distance curved navigation tunnel. After the two rows of locomotive wheels 140 are engaged with the corresponding travel rails 200, the balancing guide mechanism is engaged with the corresponding travel rails 200 to assist the tractor 100 in balancing the traction force, thereby reducing the occurrence of collisions and scrapes when the vessel 300 is traveling in a medium-to-long-distance curved navigation tunnel.

[0049] In the optional technical solution of this embodiment, the balance guide mechanism includes two horizontal guide components 130, which are arranged in parallel and spaced apart on both sides of the corresponding locomotive wheel 140.

[0050] Specific combination Figure 1 and Figure 2As shown, in this embodiment, the cross-sectional shape of the track 200 is set to an "I" shape. Two horizontal guide components 130 are arranged parallel to each other on both sides of the corresponding locomotive wheels 140, and are respectively located on both sides of the "I" shaped track 200. They cooperate with the track 200 to balance and offset the horizontal traction force of the tractor 100, reducing the possibility of collisions or scrapes between the vessel 300 and the tractor 100 when passing through the tunnel, and preventing the tractor 100 from overturning. The vertical traction force of the tractor 100 is offset by the weight of the tractor 100 itself.

[0051] In the optional technical solution of this embodiment, the horizontal guide assembly 130 includes a guide bracket 131 and a horizontal guide wheel 132. The first end of the guide bracket 131 is fixedly disposed on the bottom wall of the locomotive body 110, and the second end of the guide bracket 131 extends away from the locomotive body 110. The length of the guide bracket 131 is greater than the diameter of the locomotive wheel 140. The horizontal guide wheel 132 is rotatably connected to the second end of the guide bracket 131. The axis of the horizontal guide wheel 132 is set at an angle with the guide bracket 131, and the horizontal guide wheel 132 slides with the corresponding travel track 200.

[0052] Specific combination Figure 1 and Figure 2 As shown, in this embodiment, the axis of the horizontal guide wheel 132 is set perpendicular to the guide bracket 131. When the tractor 100 cooperates with the track 200, the two guide wheels are located on both sides of the "I"-shaped track 200 and cooperate with the top plate of the "I"-shaped track 200. While guiding the tractor to run on the track 200, the guide wheel balances and counteracts the traction force of the tractor 100 in the horizontal direction, reducing the collision and scraping of the ship 300 waiting to pass through the tunnel, and preventing the tractor 100 from overturning.

[0053] In the optional technical solution of this embodiment, the balance guide mechanism further includes two guide components 133, which are respectively disposed on two horizontal guide components 130 and cooperate with the corresponding carriage track 200.

[0054] Specific combination Figure 1 and Figure 2 As shown, two guide components 133 are respectively set on two guide supports 131, and each is located at the second end of the corresponding guide support 131. The two guide components 133 cooperate with the track 200 to guide the traction locomotive to run on the track 200, ensuring the traction effect of the traction locomotive on the vessel 300 to be passed through the tunnel.

[0055] In the optional technical solution of this embodiment, the guide component 133 includes a guide wheel, which is rotatably connected to the second end of the guide bracket 131. The axis of the guide wheel is set at an angle to the guide bracket 131, and the guide wheel rolls in cooperation with the corresponding carriage track 200.

[0056] Specific combination Figure 1 and Figure 2 As shown, in this embodiment, the axis of the guide wheel is perpendicular to the guide bracket 131, and the guide wheel is rotatably mounted on the second end of the guide bracket 131, and rolls in cooperation with the corresponding track 200. This arrangement ensures the traction effect of the locomotive on the vessel 300 passing through the tunnel, while reducing the friction of the tractor 100 when running on the track 200.

[0057] In the optional technical solutions of this embodiment, the tractor 100 is equipped with an electric drive mechanism, and the shipping tunnel ship traction device also includes multiple power supply mechanisms 400 that supply power to the electric drive mechanism.

[0058] Specific combination Figure 3 As shown, the power supply mechanism 400 is located inside the track 200. As is the case, after the tractor 100 completes the hook-up, it can charge at the power supply mechanism 400 according to its own power supply to ensure the smooth progress of the next hook-up and traction. At the same time, the power supply mechanism 400 is located inside the track 200 to avoid affecting the hook-up and traction.

[0059] In the optional technical solution of this embodiment, the ship traction device in the shipping tunnel also includes a maintenance mechanism 500. The maintenance mechanism 500 is set in a medium-to-long-distance curved navigation tunnel and is connected to the trolley track 200. The maintenance mechanism 500 includes a lifting and maintenance component for replacing a single tractor 100.

[0060] Specific combination Figure 3 As shown, in this embodiment, the maintenance mechanism 500 is located outside the entrance of the medium-to-long-distance curved navigation tunnel. The maintenance mechanism 500 is connected to the track 200. Since the maintenance mechanism 500 includes a lifting and maintenance component, when a single tractor 100 malfunctions, the position of the tractor on the track 200 can be changed through the lifting and maintenance component, so that the normal operation of the medium-to-long-distance curved navigation tunnel will not be affected by equipment failure.

[0061] The number of power supply units 400 and the location of maintenance units 500 can be adjusted according to specific circumstances. In addition, in this embodiment, three sets of power supply units 400 are installed in the medium-to-long-distance curved navigation tunnel, and the maintenance unit 500 is located 200m outside the entrance of the medium-to-long-distance curved navigation tunnel.

[0062] The ship traction process provided in this embodiment utilizes a ship traction device for shipping tunnels and includes the following steps:

[0063] Multiple tractor vehicles 100 are divided into two groups. The two groups of tractor vehicles 100 are respectively set on the running tracks 200 on both sides of the medium- and long-distance curved navigation tunnel, and the side of the tractor vehicle 100 equipped with the balance guide mechanism is set away from the center of the medium- and long-distance curved navigation tunnel.

[0064] When the first group of vessels arrived at the hooking area, the tractor 100 at the front of the first group of vessels hooked up with the first vessel 300 in the first group of vessels waiting to pass through the tunnel.

[0065] The tractor 100 located on the left bank hooks up with the starboard side of the bow of the first vessel 300 waiting to pass through the tunnel, and the tractor 100 located on the right bank hooks up with the port side of the bow of the first vessel 300 waiting to pass through the tunnel.

[0066] The first vessel 300 in the first group of vessels to be transported through the tunnel and the second vessel 300 in the first group of vessels to be transported through the tunnel were located.

[0067] The starboard side of the stern of the first vessel 300 waiting to pass through the tunnel is connected to the starboard side of the bow of the second vessel 300 waiting to pass through the tunnel by a tow rope. The port side of the stern of the first vessel 300 waiting to pass through the tunnel is connected to the port side of the bow of the second vessel 300 waiting to pass through the tunnel by a tow rope.

[0068] The tractor 100, located at the rear of the second group of vessels, hooks up with the second vessel 300 in the first group of vessels waiting to pass through the tunnel.

[0069] The tractor 100 located on the left bank hooks up with the starboard side of the stern of the second vessel 300 waiting to pass through the tunnel, and the tractor 100 located on the right bank hooks up with the port side of the stern of the second vessel 300 waiting to pass through the tunnel.

[0070] The first group of vessels entered the medium-to-long-distance curved navigation tunnel, and the second group of vessels arrived at the hooking area, repeating the above hooking and positioning steps.

[0071] After multiple groups of vessels exit the medium-to-long-distance curved navigation tunnel, they detach from their corresponding tractor units 100. The tractor units 100 then enter the charging area and, after being charged by the power supply unit 400, re-enter the hook-up area to wait.

[0072] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
