Description

Technical Field

[0001] The present invention relates to the technical field of ship tunnel traction passage, in particular to a navigation tunnel traction gantry crane. Background Art

[0002] Currently, the overall design of navigation tunnels typically utilizes mechanical traction using wire rope tractors to facilitate vessel passage through navigation tunnels. These tractors have a short operating range and are unsuitable for operation over long tunnels. The traction rope is drawn from the front drum of the drive unit, passed through a guide pulley mechanism, and connected to one end of the trolley. The traction rope is also connected to the other end of the trolley and returned to the rear drum of the drive unit via a guide pulley mechanism. The drive unit uses an electric motor and a transmission mechanism to rotate the front and rear drums in the same direction. Traction is applied through friction between the rope groove and the traction rope. One drum releases the rope while the other retracts it, allowing the trolley, positioned on the gate surface, to move forward and backward along the track, following the traction rope. The trolley's movement is entirely dependent on the traction force transmitted by the traction rope. The trolley is connected to the towed vessel by a towline. The trolley, using the tow hook and the towline, drives the towed vessel, completing the towing operation.

[0003] The mechanical traction form of the wire rope tractor is arranged in a usually straight line form in the navigation tunnel or lock, without a curved navigation section. The clear navigation width of the navigation tunnel is smaller than the width of the ship, and it is relatively easy to hang the cable.

[0004] However, in curved navigation sections, the clear navigation width needs to be larger than the ship width to meet the requirements for safe navigation of ships. The hanging cable and traction method of the mechanical traction form of the wire rope tractor cannot meet the above requirements. If the self-propelled form is used, it will cause pollution to the air in the tunnel during long-term operation. Summary of the Invention

[0050] The following embodiments of the present invention are described in detail with reference to the accompanying drawings. In the absence of conflict, the following embodiments and features in the embodiments may be combined with each other.

[0051] like Figure 1 、 Figure 2 As shown, the navigation tunnel traction gantry crane provided in this embodiment includes a trolley operating mechanism 100, a gantry crane main beam 200, a cable winding mechanism 300 and a hydraulic component 400; the gantry crane main beam 200 is arranged on the top of the trolley operating mechanism 100, and the trolley operating mechanism 100 slides along the curved guide rail on the shore of the navigation tunnel; the cable winding mechanism 300 is installed on the gantry crane main beam 200, and the cable winding mechanism 300 is used to extend a mooring rope 330 to connect with a ship to tow the ship; a hydraulic component 400 is provided between the trolley operating mechanism 100 and the gantry crane main beam 200, and the hydraulic component 400 is used to drive the gantry crane main beam 200 to move toward or away from the trolley operating mechanism 100, so as to drive the gantry crane main beam 200 to rise and fall.

[0052] The navigation tunnel traction gantry crane provided in this embodiment lowers the height of the gantry crane main beam 200 by starting the hydraulic component 400, and the mooring rope 330 extended from the cable winding mechanism 300 is connected to the ship's mooring bollard. The trolley running mechanism 100 slides and moves along the curved guide rail on the shore of the navigation tunnel, so that the navigation tunnel traction gantry crane moves in a curve as a whole, and the mooring rope 330 of the cable winding mechanism 300 drives the ship to move in a curve. It is suitable for curved navigation tunnels. After reaching the end of the tunnel, the hydraulic component 400 is started to raise the gantry crane main beam 200, and the ship starts, passes under the gantry crane main beam 200, and leaves the navigation tunnel. The ship can be towed using a shorter towing rope without affecting the normal departure of the ship, thereby alleviating the technical problems in the prior art of difficulty in towing and hanging ships in long-distance curved navigation tunnels and pollution of the air in the tunnel caused by long-term operation in a self-propelled mode.

[0053] Based on the above embodiments, Figure 3 As shown, in an optional embodiment, the cable winding mechanism 300 provided in this embodiment includes a drive motor 310, a cable drum 320 and a mooring rope 330; the drive motor 310 is installed on the gantry crane main beam 200, the drive shaft of the drive motor 310 is connected to the cable drum 320, one end of the mooring rope 330 is connected to the cable drum 320, and the mooring rope 330 is wound around the cable drum 320.

[0054] Specifically, the fixed end of the drive motor 310 is fixed to the main beam 200 of the gantry crane. The driving end of the drive motor 310 drives the cable drum 320 to rotate along the axial direction of the driving end, driving the cable drum 320 to rotate, thereby realizing the rope release or rope retraction operation of the mooring rope 330.

[0055] In an optional embodiment, the navigation tunnel traction gantry crane further includes a rope blocking component 340; the rope blocking component 340 is connected to the gantry crane main beam 200, and the rope blocking component 340 has a roller portion, which is located below the gantry crane main beam 200, and the roller portion is used to abut against the mooring rope 330 to limit the rotation angle of the mooring rope 330.

[0056] Specifically, the rope blocking component 340 includes a roller part and a connecting rod. The roller part is connected to the bottom outer wall of the gantry crane body through the connecting rod. The roller part is configured as a rollable pulley. After the mooring rope 330 is connected to the ship, the roller part serves to limit the rotation angle of the mooring rope 330, thereby preventing the mooring rope 330 from contacting the gantry crane main beam 200, and effectively preventing the mooring rope 330 from affecting the use of other electrical structures on the gantry crane main beam 200.

[0057] like Figure 4As shown, in an optional embodiment, the hydraulic assembly 400 includes a hydraulic cylinder 410, a hinge support 420, a piston rod 430 and a connecting head 440; the hydraulic cylinder 410 is connected to the trolley running mechanism 100 through the hinge support 420, the piston rod 430 is arranged in the hydraulic cylinder 410, and one end of the piston rod 430 extending out of the hydraulic cylinder 410 is connected to the gantry crane main beam 200 through the connecting head 440.

[0058] Specifically, the bottom of the hydraulic cylinder 410 is connected to the lower crossbeam on the trolley running mechanism 100 through the hinge support 420. The liquid oil in the hydraulic cylinder 410 provides power for the piston rod 430, causing the piston rod 430 to rise and fall, and then the piston rod 430 drives the gantry crane main beam 200 to rise and fall through the connecting head 440.

[0059] In an optional embodiment, the navigation tunnel traction gantry crane further includes a lifting mechanism 500; the lifting mechanism 500 is arranged on the gantry crane main beam 200, and the lifting mechanism 500 is configured to be able to move along the gantry crane main beam 200; the navigation tunnel traction gantry crane further includes a hook mechanism 600; the hook mechanism 600 is connected to the lifting mechanism 500, and the hook mechanism 600 is configured to be able to connect to a ship for lifting the ship.

[0060] Specifically, the lifting mechanism 500 is installed on the top of the gantry crane main beam 200, and the lifting mechanism 500 is arranged on the track of the main beam. Under the action of the hydraulic gantry leg device, when the gantry crane main beam 200 is raised, the navigation clearance height requirement of the ship in the navigation tunnel is met. The lifting mechanism 500 can inspect the ancillary facilities in the navigation tunnel. In terms of gantry crane function, it cooperates with the hook mechanism 600 to meet the requirements of daily inspection and maintenance of ancillary facilities in the navigation tunnel and salvage of sunken ships.

[0061] In an optional embodiment, the navigation tunnel traction gantry crane further includes a control mechanism 700 ; the control mechanism 700 is disposed on the gantry crane main beam 200 , and the control mechanism 700 is electrically connected to the hydraulic assembly 400 , the lifting mechanism 500 and the hook mechanism 600 .

[0062] Specifically, the control mechanism 700 is specifically configured as a control box or a central control room, and the control mechanism 700 controls the operation of the lifting mechanism 500 , the hydraulic assembly 400 and the hook mechanism 600 .

[0063] In addition, the control mechanism 700 can also be connected to an external wireless control device, and the wireless control device can be used to transmit a control signal to the control mechanism 700 to achieve remote control.

[0064] In order to provide protection, in an optional embodiment, a protective railing 800 is provided on the top of the gantry crane main beam 200.

[0065] like Figure 5 、 Figure 6As shown, the ship towing method based on the navigation tunnel traction gantry provided in this embodiment includes the following steps: two ships are parked at the entrance of the navigation tunnel, the first traction gantry 10 is driven to the top of the mooring post at the bow of the first ship through the trolley operating mechanism 100, the cable winding mechanism 300 is operated to lower the mooring rope 330 on the first traction gantry 10 to connect with the mooring post of the first ship, and the trolley operating mechanism 100 and the cable winding mechanism 300 on the forward direction side of the first traction gantry 10 are operated at the same time, the first traction machine is operated to the position where the angle between the mooring rope 330 and the ship is 30°, and the trolley operating mechanism 100 and the cable winding mechanism 300 on the forward direction side stop running at the same time.

[0066] In an optional embodiment, the first ship is cross-connected with the mooring post of the second ship through a mooring rope 330; the second traction gantry crane 20 travels to the mooring post at the bow of the second ship through the trolley operating mechanism 100, and the cable winding mechanism 300 is operated to lower the mooring rope 330 on the second traction gantry crane 20 to connect with the mooring post of the second ship, and the trolley operating mechanism 100 and the cable winding mechanism 300 of the second traction gantry crane 20 are operated at the same time, and the second gantry crane runs to a position where the angle between the mooring rope 330 and the ship is 30°, and the trolley operating mechanism 100 and the cable winding mechanism 300 on the forward direction side stop running at the same time; at the same time, the trolley movement mechanism on the first traction gantry crane 10 and the trolley operating mechanism 100 on the second traction gantry crane 20 are traveling in the navigation tunnel.

[0067] The specific implementation method of ship towing is as follows: Implementation method under ship towing conditions:

[0068] (1) Two ships are parked at the entrance of the navigation tunnel. The first traction gantry crane 10 is driven to the mooring post at the bow of the first ship through the trolley operating mechanism 100. The cable winding mechanism 300 on the forward direction side is operated to lower the mooring rope 330 on the first traction gantry crane 10 to connect with the mooring post of the first ship. At the same time, the trolley operating mechanism 100 and the cable winding mechanism 300 on the forward direction side of the first traction gantry crane 10 are operated. The first gantry crane is operated until the angle between the mooring rope 330 and the ship is about 30°. The trolley operating mechanism 100 and the cable winding mechanism 300 on the forward direction side stop operating at the same time.

[0069] (2) The first ship is cross-connected to the second ship's mooring bitt via the mooring line 330 .

[0070] (3) The second traction gantry crane 20 is driven to the mooring post at the bow of the second vessel via the trolley operating mechanism 100. The cable reeling mechanism 300 is operated to lower the mooring line 330 on the second traction gantry crane 20 to connect with the mooring post of the second vessel. The trolley operating mechanism 100 and the cable reeling mechanism 300 of the second traction gantry crane 20 are operated simultaneously. The second gantry crane is operated until the angle between the mooring line 330 and the vessel is approximately 30°. The trolley operating mechanism 100 and the cable reeling mechanism 300 on the forward direction side are stopped simultaneously. At this point, the vessel towing operation is completed. The first and second trolley traction gantry cranes 20 and the trolley operating mechanism 100 are simultaneously started to travel in the navigation tunnel.

[0071] When a vessel reaches the end of a navigation tunnel, the trolley operating mechanisms 100 of the first and second traction gantry cranes 20 are deactivated, the forward-facing cable reeling mechanism 300 is activated to release the ropes, and the mooring ropes 330 attached to the bow and stern mooring posts of the first and second vessels, as well as the mooring rope 330 between the two vessels, are simultaneously released. The forward-facing cable reeling mechanism 300 is activated to retract the ropes, and the hydraulic gantry leg devices of the first and second traction gantry cranes 20 are simultaneously activated to raise the hydraulic gantry legs. When the gantry cranes' clearance height meets the requirements for safe departure, the vessels activate their free power systems and exit the navigation tunnel in sequence.

[0072] The above operations complete the implementation method for the ship to pass through the traction gantry crane in the navigation tunnel and safely leave the navigation tunnel. The direction can also be operated according to the above method.

[0073] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or replace some or all of the technical features therein with equivalents.
