Description

Technical Field

[0001] This invention relates to the field of ship traction technology, and in particular to a ship lock traction device and a stable lock passage method. Background Technology

[0002] When ships navigate to narrow sections of the channel (the lock width of a narrow channel is 18m, and the typical ship width for passing through the Three Gorges Dam ship lift is 16.6m), the large mass and inertia of the ships, coupled with their simple power output, make maneuvering difficult and increase the risk of collisions. To address this issue, tugboats are typically used to adjust the ship's navigation. However, using tugboats involves significant time for scheduling and towing operations, and even smaller tugboats cannot operate effectively in confined spaces such as locks. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide a ship lock passage traction device and a stable lock passage method, which can achieve efficient, fast and stable lock passage.

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

[0005] A ship lock passage traction device includes a main body, which is fixedly installed within a dam body. Reinforcing columns are installed at both ends of the main body, and a traction drive chamber is located within each reinforcing column. A winding wheel is installed within the traction drive chamber, and a traction cable is wound around the winding wheel. The traction cable moves from one end of the lock exit to one end of the lock entrance via a traction cable moving mechanism. The traction cable moving mechanism includes a traction chute located within the main body, with its opening facing outwards and one end extending and communicating with the outward opening of the traction drive chamber. A first belt conveyor mechanism is installed within the traction chute, which drives a traction slider to move back and forth between the lock exit and lock entrance ends. The traction slider has a locking mechanism that, when the traction slider reaches the winding wheel, hooks the traction cable and pulls it.

[0006] A wire hole is provided in the inner wall of the rear side of the traction chute. The upper and lower ends of the wire hole are connected to the traction chute through the drive traction groove and the traction guide groove. A guide traction wheel is installed in the traction guide groove, and a drive traction wheel is installed in the drive traction groove. The drive traction wheel is driven by a drive motor fixedly installed in the drive traction groove. The reset traction rope passes around the drive traction wheel and the guide traction wheel and is fixedly connected to the traction slider at both ends. The back of the traction slider is slidably installed in the guide groove through the guide slider. The guide groove is located in the inner wall of the rear side of the traction chute.

[0007] The traction chute has an arc-shaped groove connected to the front inner wall near the lock exit; the traction chute has an opening connected to the front inner wall near the lock entrance, and when one end of the traction cable is pulled to the opening position, the clamp connects with the opening; the end of the traction cable extending out of the traction drive room is fixedly equipped with a traction rope knot.

[0008] The right side of the winding wheel is rotatably equipped with a traction guide pulley, which is passed through when the wheel is pulled out.

[0009] A method for stabilizing ship passage through locks includes the following steps:

[0010] Step 1) First, drive the traction wheel to rotate and move the traction slider towards the winding wheel side through the traction reset traction rope, and finally move it until the bayonet is flush with the arc-shaped groove; at this time, lift the traction cable by the wedge-shaped part at the upper end of the traction slider so that the traction cable falls into the bayonet, and then drive the traction wheel to bring the traction slider to the lower end to bring one end of the traction cable to the opening position; since the bayonet and the opening are connected, it is convenient for the staff to take out the traction cable; while the buffer block moves forward to the maximum extent in the buffer groove, at this time, the electromagnet is in the de-energized state;

[0011] Step 2) When a vessel passes by and is unable to move and requires towing, the staff removes the towing rope knot from the opening and ties it to the front of the vessel.

[0012] Step 3) At this time, the drive motor drives the winding wheel to rotate, gradually retracting the traction cable, thereby pulling the ship located in the lock channel upward and gradually entering the lock channel;

[0013] Step 4) During this process, when the vessel deviates to one side during towing, the radar locator detects the distance between the vessel and the main body of the device in real time, thereby buffering the vessel and the main body of the device when the vessel approaches the main body of the device.

[0014] Step 5) The buffering process is as follows: The electromagnet is energized according to the ship's status detected by the radar locator. When it is necessary to move the buffer block to a suitable position, the electromagnet is energized, which pushes the limiting block downward and presses against the adjusting rope. At the same time, the adjusting rope rotates. When the adjusting rope moves, it will drive the buffer block to a suitable position. By adjusting the position of multiple sets of buffer blocks, the ship can avoid direct collision with the main body of the device.

[0015] Step 6) When the traction work is completed, drive the traction wheel to rotate and move the traction slider upward through the traction reset traction rope, and finally move it to the state where the bayonet is flush with the arc-shaped groove; at this time, lift the traction cable by the wedge-shaped part at the upper end of the traction slider so that the traction cable falls into the bayonet again, and then drive the traction wheel to bring the traction slider to the lower end to bring one end of the traction cable to the opening position, so as to facilitate the next operation by the staff.

[0016] This invention provides a ship lock passage traction device and a stable lock passage method, which have the following technical advantages:

[0017] 1) When ships are passing through, some ships with large loads or large weights are difficult to maneuver in narrow areas such as locks. This device can be used to tow them and assist them in passing through. Compared with the towing boats used in traditional towing methods, this device is more suitable for use in narrow spaces, such as locks when passing through dams. Moreover, the scheduling speed of this device is fast and the response time is short, which can greatly increase the efficiency of navigation and towing.

[0018] 2) By adopting a traction cable moving mechanism, the traction cable can be moved into the slot when the traction slider is moved to the designated position. Then, the traction slider is moved up and down by the belt conveyor mechanism, thereby completing the transfer of the traction cable from the lock exit end to the lock entrance end without manual operation.

[0019] 3) By cooperating with the belt conveyor mechanism and using limiting components to lock, move or release the buffer block, the movement of the buffer block is achieved after detection by the radar locator during the process, thereby achieving effective buffering.

[0030] like Figure 2 As shown, a ship lock passage traction device includes a device body 104 horizontally fixedly installed in the dam body 101. Reinforcing columns 102 are fixedly installed at both ends of the device body 104 (lock exit a and lock inlet b) and located in the dam body 101. The ship lock passage traction device is installed in the device body 104 and the reinforcing columns 102.

[0031] To ensure uniform traction force, ship passage traction devices are installed inside the dam body 101 on both sides of the lock channel 125. The ship passage traction devices installed on the left and right sides are symmetrical and are used to traction ships approaching the left and right sides of the lock channel 125.

[0032] like Figure 2 As shown, the ship lock towing device includes a towing drive chamber 123 located within a reinforcing column 102 at one end of the lock exit (represented by a in the figure). A winding wheel 124 is rotatably mounted within the towing drive chamber 123, and is driven to rotate by a driver located within the inner wall of the towing drive chamber 123. A traction guide pulley 126 is rotatably mounted on the right side of the winding wheel 124, and a towing cable 128, pulled out by the traction guide pulley 126, is wound around the winding wheel 124. When a ship (represented by c in the figure) enters the lock channel 125 through the lock entrance (represented by b in the figure), the towing cable 128 is extended and connected to the front of the ship for easy towing operations.

[0033] like Figure 2-3 As shown, the traction mechanism is located at the exit a end of the lock for easy traction; while the ship's entry point is at the entrance b end of the lock. There is a long distance between a and b. In order to facilitate the quick and easy manual attachment of the traction cable 128 at the exit a end of the lock to the ship at the entrance b end of the lock, a traction cable moving mechanism is required.

[0034] like Figure 2-3As shown, specifically, the traction cable moving mechanism includes a traction chute 131 with an outward opening inside the device body 104. The opening at one end of the traction chute 131 extends toward the winding wheel 124 and communicates with the right end opening of the traction drive chamber 123. A guide chute 177 is provided in communication with the inner rear wall of the traction chute 131.

[0035] An arc-shaped groove 151 is provided at the connection between the traction chute 131 and the traction drive chamber 123, and the arc-shaped groove 151 has a certain length.

[0036] A traction slider 147 is slidably disposed within the traction chute 131. A guide slider 146, which can slide within a guide chute 177, is fixedly disposed on the back of the traction slider 147. A through-hole 148 with an upward opening is disposed within the traction slider 147, which is used to hook the traction cable 128. A wire hole 144 is disposed on the inner rear wall of the traction chute 131, and the upper and lower ends of the wire hole 144 are connected to the traction chute 131 through a drive traction groove 143 and a traction guide groove 152. A guide traction wheel 153 is rotatably disposed within the traction guide groove 152, and a drive traction wheel 142 is rotatably disposed within the drive traction groove 143. The drive traction wheel 142 is driven by a drive motor fixedly disposed within the drive traction groove 143.

[0037] One end of the traction slider 147 is fixedly connected to a reset traction rope 145. The other end of the reset traction rope 145 extends into the wire hole 144 after passing through the drive traction wheel 142, and is fixedly connected to the upper end of the traction slider 147 after passing through the guide traction wheel 153. The drive traction wheel 142 can drive the traction slider 147 to move up and down. When the traction slider 147 moves to the winding wheel 124, it can hook the traction cable 128 through the latch 148 and pull the traction cable 128, thereby pulling its end to the lock entrance b of the lock channel 125 for easy retrieval.

[0038] Preferably, the traction chute 131 has an opening 141 connected to the inner wall of the front side near the lower end. When one end of the traction cable 128 is pulled to the position of the opening 141, the latch 148 is connected to the opening 141. At this time, one end of the traction cable 128 can be taken out through the opening 141.

[0039] Preferably, a traction rope knot 129 is fixedly provided at the end of the traction cable 128 extending out of the traction drive chamber 123. The traction rope knot 129 is used to prevent the traction cable 128 from falling off the latch 148 when the traction slider 147 moves, and plays a limiting role.

[0040] like Figure 1As shown, a ship lock passage buffer device includes a buffer chute 133 opened to the right within the main body 104 of the device. A transmission groove 103 is provided on the upper inner wall of the buffer chute 133, and a pulley 108 is disposed within the transmission groove 103, driven by a transmission assembly. A transmission guide groove 121 is provided on the lower inner wall of the buffer chute 133, and a transmission guide wheel 122 is rotatably disposed within the transmission guide groove 121. Two adjusting ropes 119 extending through the buffer chute 133 are wound between the pulley 108 and the transmission guide wheel 122. A buffer base block 113 is slidably disposed within the buffer chute 133, and the number of buffer base blocks 113 in a single buffer chute 133 is one or more. Through holes 159 are symmetrically arranged and penetrate through the buffer base block 113, and the two adjusting ropes 119 extend through the through holes 159 respectively. A limiting component is provided within the through hole 159, which can tighten or loosen the adjusting rope 119. Thus, when the adjusting rope 119 rotates, the buffer block 113 can move upward, downward, or remain stationary.

[0041] like Figure 1 As shown, the transmission assembly includes a power input wheel 105. One side of the power input wheel 105 is coaxially connected to the traction guide pulley 126. The lower end of the power input wheel 105 meshes with the power supplement gear 106. The lower end of the power supplement gear 106 meshes with the driven wheel 107. The driven wheel 107 is coaxially connected to the pulley 108.

[0042] The transmission assembly has two power sources. First, when the traction cable 128 is pulled out or retracted, the friction between the traction cable 128 and the guide pulley 126 drives the guide pulley 126 to rotate. The guide pulley 126 transmits the rotational output torque to the power input wheel 105. When the power input wheel 105 rotates, it can drive the driven wheel 107 to rotate via the power supplement gear 106, thereby driving the adjusting rope 119 to rotate. Second, a power assistance device, which is a motor, is connected to the upper end of the power supplement gear 106. When the power input wheel 105 rotates, the power assistance device provides additional power output to the power supplement gear 106. That is, when the power input wheel 105 cannot drive the adjusting rope 119 to rotate, the power assistance device provides additional power to the driven wheel 107.

[0043] Both the power assistance component and the limiting component are controlled and linked by a controller. That is, when the limiting component limits the relative position of the adjusting rope 119 and the buffer block 113, the power assistance component is activated and provides additional power assistance to the power supplement gear 106. Thus, when the adjusting rope 119 and the buffer block 113 are locked, the transmission assembly drives the adjusting rope 119 to agitate.

[0044] like Figure 5-7As shown, the limiting component includes a limiting hole 112 disposed within the buffer base 113 and communicating with the through hole 159. Multiple locking buckles 158 are disposed within the limiting hole 112 and communicating with it. Each locking buckle 158 has a limiting cavity 162. An adjusting rope 119 passes through the limiting hole 112 and the limiting cavity 162. Within the buffer base 113, the locking buckles 158 on the two sections of the adjusting rope 119 are independently locked; that is, when one side of the adjusting rope 119 is locked with its corresponding locking buckle 158, the other side of the adjusting rope 119 is released from its corresponding locking buckle 158. This allows for upward or downward movement when the adjusting rope 119 is disturbed.

[0045] like Figure 5-7 As shown, a limiting block 171 is slidably disposed within the limiting cavity 162 of the locking buckle 158. A movable cavity 167 is disposed within the limiting block 171, and an adjusting rope 119 passes through the movable cavity 167. Three metal retaining balls 166 are placed within the movable cavity 167. Three through grooves 178 are provided on the lower inner wall of the movable cavity 167, allowing the metal retaining balls 166 to partially slide out but not completely.

[0046] A movable magnet 169 is fixedly installed on the upper end face of the limiting block 171, and an electromagnet 168 is fixedly installed on the upper inner wall of the limiting cavity 162, which is opposite to the movable magnet 169. By turning the electromagnet 168 on and off, it can generate the same magnetism as the upper end of the movable magnet 169, thereby pushing the movable magnet 169 to move downward.

[0047] The lower side of the limiting block 171 is wedge-shaped, and the lower inner wall of the limiting cavity 162 is also wedge-shaped. The wedge-shaped design of the lower part facilitates the pushing of the metal ball 166 through the through groove 178.

[0048] The inner walls of the left and right sides of the limiting cavity 162 are connected by a push-pull groove 164. A push-pull slider 163 is fixedly mounted on the left and right end faces of the limiting block 171. The push-pull slider 163 extends into the push-pull groove 164 and can slide up and down within the push-pull groove 164. A push-pull spring 165 is fixedly connected between the push-pull slider 163 and the inner wall of the push-pull groove 164.

[0049] Under normal conditions, the limiting block 171 is pushed upward by the pushing slider 163 through the pushing spring 165. At this time, the lower end of the limiting block 171 is spaced from the lower inner wall of the limiting cavity 162, and the metal ball 166 protrudes from the through groove 178. When the electromagnet 168 is energized, the limiting block 171 moves downward, and the lower inner wall of the limiting cavity 162 pushes the metal ball 166 into the movable cavity 167, where the metal ball 166 clamps the adjusting rope 119. Through the abutment and restriction of the metal ball 166, the adjusting rope 119 can drive the buffer base block 113 to move up and down in the buffer groove 133 when it rotates.

[0050] A knot 161 is fixedly provided on the adjusting rope 119. When the metal locking ball 166 retracts into the movable cavity 167, the metal locking ball 166 abuts against and locks the adjusting rope 119. The knot 161 plays the role of upper and lower limit, preventing the adjusting rope 119 from coming off the locking buckle 158.

[0051] like Figure 8 As shown, in order to match the adjusting rope 119, the pulley 108 and the transmission guide wheel 122 are both provided with rope knot slots 172 that cooperate with the rope knot 161, so that the adjusting rope 119 can be pulled when the pulley 108 rotates.

[0052] like Figure 4 As shown, an impact block 118 is provided on one side of the buffer base block 113. A connecting swing rod 114 is rotatably connected between the left side of the impact block 118 and the right side of the buffer base block 113. A hydraulic buffer push rod 155 is rotatably connected between the connecting swing rod 114 and the buffer base block 113. The hydraulic buffer push rod 155 can drive the connecting swing rod 114 to swing and play a role in reducing the pressure on the right side of the impact block 118.

[0053] A radar locator 156 is fixedly installed on the right end face of the impact block 118. Both the electromagnet 168 and the radar locator 156 are controlled by the controller. When the radar locator 156 detects the relative position of the vessel and the impact block 118, the controller analyzes the information and then controls the electromagnet 168 to switch on and off. This allows the position of the impact block 118 to be adjusted in real time according to the vessel's status when the towing cable 128 tightens and tows the vessel, thereby providing a buffer.

[0054] Preferably, in order to reduce the collision between the ship and the right side of the impact block 118, a plastic pad 117 is fixedly provided on the right side of the impact block 118.

[0055] Working principle and process:

[0056] 1) First, drive the traction slider 147 to move down to the maximum extent in the traction groove 131. At this time, the traction cable 128 is pulled out to the opening 141. Since the bayonet 148 is connected to the opening 141, it is convenient for the staff to take out the traction cable 128. Meanwhile, the buffer block 113 moves forward to the maximum extent in the buffer groove 133. At this time, the electromagnet 168 is in the de-energized state.

[0057] 2) When a vessel passes by and is unable to move and requires towing, the staff removes the towing rope knot 129 at opening 141 and ties it to the front of the vessel.

[0058] 3) At this time, the drive motor drives the winding wheel 124 to rotate, gradually retracting the traction cable 128, thereby pulling the ship located in the lock channel 125 upward and gradually entering the lock channel 125.

[0059] 4) During this process, when the ship deviates to one side during towing, the radar locator 156 detects the distance between the ship and the main body 104 in real time, thereby buffering the ship and the main body 104 when the ship approaches the main body 104.

[0060] 5) The buffering process is as follows: Electromagnet 168 is energized according to the ship's status detected by radar locator 156. When it is necessary to move buffer block 113 to a suitable position, electromagnet 168 is energized, which pushes limiting block 171 downward and presses against adjusting rope 119. When the towing cable 128 is retracted, the towing cable 128 drives the guide pulley 126 to rotate, and the rotation of the guide pulley 126 drives the transmission assembly to move, which in turn causes adjusting rope 119 to rotate. When adjusting rope 119 moves, it drives buffer block 113 to move. By adjusting the position of multiple sets of buffer blocks 113, the ship can avoid direct collision with the main body of the device 104.

[0061] 6) When the traction work is completed, drive the traction wheel 142 to rotate and drive the traction slider 147 to move upward through the traction reset traction rope 145, and finally move it to the state where the bayonet 148 is flush with the arc-shaped groove 151; at this time, the traction cable 128 is lifted by the wedge-shaped part at the upper end of the traction slider 147 so that the traction cable 128 falls into the bayonet 148, and then the traction wheel 142 is driven to bring the traction slider 147 to the lower end, so that one end of the traction cable 128 can be brought to the position of the opening 141, which is convenient for the next operation by the staff.

[0062] The beneficial effects of this invention are as follows: When ships are passing through, some ships with large loads or large weights are difficult to maneuver in narrow areas such as locks. This device can be used to tow them and assist them in passing through. Compared with the towing boats used in traditional towing methods, this device is more suitable for use in narrow spaces, such as locks when passing through dams. Moreover, the device has a fast scheduling speed and short response time, which can greatly increase the efficiency of navigation and towing.
