A high-lift matrix rack and pinion ship lift navigation facility

Abstract

The present invention discloses a high-lift matrix rack and pinion ship lift navigation facility, comprising two identical rack and pinion ship lift routes connected in parallel, each of which can operate independently. Each ship lift route comprises an upper lock working door and an upper lock opening and closing machine, a cabin chamber, a lower lock working door and a lower lock opening and closing machine. During the docking process of any ship lift route with the upstream and downstream locks, the gap between the ship holding compartments of the two rack and pinion ship lifts on the same line is pushed out through a U-shaped sealing frame at the end of the ship holding compartment on one side, and is tightly sealed against the vertical stop level surface at the end of the ship holding compartment on the other side. By opening the cabin doors at both ends of the ship holding compartment, the water areas of the two ship holding compartments are connected, thereby allowing two ships to successively enter the water areas of the two serially arranged ship holding compartments, thereby realizing the serial lifting and lowering operation of the two ship lifts. The present invention can meet the needs of larger ship passing scales and higher navigation heads, reduce operating costs, and improve navigation efficiency.

Description

Technical Field

[0001] The present invention relates to the technical field of ship lifts, and more particularly to a high-lift matrix rack and pinion ship lift navigation facility. Background Art

[0002] As a navigation facility, vertical ship lifts are increasingly used in water conservancy hubs due to their shortened dam transit times and suitability for high-dam navigation. Vertical ship lifts can be categorized by their lifting mechanism into two types: wire rope winch and rack and pinion. Compared to wire rope winch ship lifts, rack and pinion ship lifts offer greater safety and reliability and can accommodate larger ship handling capacity and higher navigable water heads. The increased handling capacity and lifting height have far less impact on the layout and scale of the rack and pinion ship lift's core equipment than with wire rope winch lifts, and have virtually no impact on the smooth operation of the ship's cabin.

[0003] However, the cabin sections of existing vertical ship lifts all utilize a single-bay design. As ships grow larger and navigation heads rise, the size and manufacturing and installation complexity of the rack and pinion ship lift's core equipment inevitably increase. Furthermore, due to the limited size of some core ship lift components, single-bay ship lifts cannot meet the navigation needs of longer fleets. Furthermore, with the growing demand for navigational capacity, single-line ship lifts struggle to meet annual throughput requirements. Summary of the Invention

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a high-lift matrix rack and pinion ship lift navigation facility to solve the above-mentioned problems.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a high-lift matrix rack and pinion ship lift navigation facility, comprising two identical rack and pinion ship lift routes connected in parallel, each ship lift route operating independently, each ship lift route comprising an upper lock working door and an upper lock opening and closing machine, a cabin room, a lower lock working door and a lower lock opening and closing machine, characterized in that the cabin room of each ship lift route comprises a tower structure and a top machine room thereof, and two rack and pinion ship lifts connected in series; each rack and pinion ship lift comprises a ship holding cabin, a counterweight, a drive mechanism rack and a safety mechanism nut column, a counterweight guide rail and the longitudinal guide rails of the cabin; the ship holding cabin is balanced by a counterweight of the same weight, suspended by a steel wire rope passing through a pulley group in the top machine room, and is lifted and lowered in the cabin room surrounded by the inner side of the tower structure and the upper and lower gate working doors; when one of the ship lift routes is in a docking state, the gap between the two ship holding cabins of the two rack and pinion ship lifts is sealed by a U-shaped sealing frame, and the water areas of the two ship holding cabins are connected by opening the cabin doors at both ends of the ship holding cabins, so that the two ships successively enter the water areas of the two ship holding cabins arranged in series; when the docking process of the ship lift on this line is completed, the lifting process of the ship lift can be started.

[0006] Preferably, for the two ship lifts in each ship lift route, four sets of drive mechanism pinions and four sets of safety mechanism short screws are symmetrically arranged on both sides of the ship holding compartment, and their positions correspond to the four grooves of the tower structure. On the wall of each groove, a set of drive mechanism racks and a set of safety mechanism nut columns are laid respectively. Through the operation of the drive mechanism pinions along the racks, the ship holding compartment is vertically lifted and lowered along the longitudinal guide rails of the compartment.

[0007] Preferably, for the two ship lifts on each ship lift route, when the driving mechanism pinion of the ship holding box climbs along the driving mechanism rack, the short screw of the safety mechanism running synchronously with the driving mechanism on the ship holding box idles in the safety mechanism nut column. When an accident occurs in which the balance is destroyed, the ship holding box can be safely locked on the nut column through the short screw of the safety mechanism.

[0008] Preferably, for the two ship lifts on each ship lift route, one end of the steel wire rope is connected to the ship holding chamber and is guided through a pulley block, and then the other end is connected to the counterweight.

[0009] Preferably, for any ship lift of each ship lift route, the counterweight is vertically raised and lowered along the counterweight guide rail.

[0010] Preferably, for the two ship lifts of each ship lift route, the ship holding compartment and both ends of the ship holding compartment are provided with cabin doors.

[0011] Preferably, for the two ship lifts of each ship lift route, U-shaped sealing frames are provided at both ends of the ship holding compartment, and a U-shaped sealing frame is provided at one end of the ship holding compartment close to the downstream side.

[0012] Preferably, for the two ship lifts on each ship lift route, the U-shaped sealing frames at both ends of the ship holding chamber are pushed by the driving cylinder, and the end water-stop rubbers thereof are respectively pressed against the upper gate working door and the stainless steel vertical water-stop panel at the end of the ship holding chamber, forming a gap sealing space connecting the end of the ship holding chamber with the upper gate working door and the end of the ship holding chamber.

[0013] Preferably, for the two ship lifts on each ship lift route, the U-shaped sealing frame on the downstream side of the ship holding compartment is pushed by the driving cylinder, and its end water-stop rubber is docked with the stainless steel vertical water-stop panel of the lower gate working door, forming a gap sealing space connecting the end of the ship holding compartment and the lower gate working door.

[0014] Technical effects and advantages of the present invention:

[0015] The overall design of the present invention is simple and the structural design is reasonable. The two parallel rack and pinion ship lift routes operate independently. The two rack and pinion ship lifts on a single ship lift route can flexibly adopt two ship holding compartments to operate in series or a single ship holding compartment according to the size of the fleet. The matrix-type four-seat rack and pinion ship lift can meet the purpose of simultaneous navigation of large-scale fleets, reduce operating costs, and improve navigation efficiency; at the same time, the rack and pinion ship lift ensures the stability of the lifting and lowering operation of the high-lift ship lift.

[0030] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0031] An embodiment of the present invention provides a high-lift matrix rack and pinion ship lift navigation facility. This high-lift matrix rack and pinion ship lift navigation facility utilizes two rack and pinion ship lift lines running in parallel. The ship lift carriages of the two ship lifts on each ship lift line can operate in series. This high-lift matrix rack and pinion ship lift navigation facility can accommodate larger ship handling capacity and higher navigation head, reducing operating costs and improving navigation efficiency. The specific structural configuration of each mechanism and component is as follows:

[0032] In some embodiments, as Figure 1-12As shown, two identical rack and pinion ship lift routes are connected in parallel, and each ship lift route can operate independently. Each ship lift route includes an upper gate working door 1 and an upper gate hoist 2, a cabin room, a lower gate working door 3 and a lower gate hoist 4. The cabin room of each ship lift route consists of a tower structure 5 and its top machine room 6, and two rack and pinion ship lifts connected in series. Each rack and pinion ship lift consists of a ship holding compartment (7, 8), a counterweight 9, a drive mechanism rack 10 and a safety mechanism nut column 11, a counterweight guide rail 20 and a ship cabin longitudinal guide rail 19. The ship holding compartment (7, 8) is balanced by a counterweight 9 of the same weight, and is suspended by a wire rope 12 that passes through a pulley block 13 on the top machine room 6. It is raised and lowered in the cabin room surrounded by the inner side of the tower structure 5 and the upper gate working door 1 and the lower gate working door 3. When one of the ship lift routes is in a docking state, the gap between the two ship carriages (7, 8) of the two rack and pinion ship lifts is sealed by a U-shaped sealing frame 14, and the ship carriage doors 15 at both ends of the ship carriages are opened to connect the water areas of the two ship carriages (7, 8), thereby allowing two ships to successively enter the water areas of the two serially arranged ship carriages (7, 8). When the docking process of the ship lifts on this line is completed, the lifting process of the ship lift can be started.

[0033] In some embodiments, as Figure 1-5 As shown, four sets of driving mechanism pinions 16 and four sets of safety mechanism short screws 17 are symmetrically arranged on both sides of the ship-carrying compartment (7, 8), and their positions correspond to the four grooves of the tower column structure 5. On the wall of each groove, a set of driving mechanism racks 10 and a set of safety mechanism nut columns 11 are laid respectively. Through the operation of the driving mechanism pinions 16 along the racks 10, the ship-carrying compartment (7, 8) is vertically raised and lowered along the longitudinal guide rails 19 of the compartment. When the driving mechanism pinions 16 of the ship-carrying compartment (7, 8) climb along the driving mechanism racks 10, the safety mechanism short screws 17 on the ship-carrying compartment (7, 8) that run synchronously with the driving mechanism are idle in the safety mechanism nut columns 11. When an accident occurs in which the balance is destroyed, the ship-carrying compartment (7, 8) can be safely locked on the nut columns 11 by the safety mechanism short screws 17.

[0034] In some embodiments, as Figure 1-2 As shown, one end of the steel wire rope 12 is connected to the ship-bearing compartment (7, 8), and after being guided by the pulley block 13, the other end is connected to the counterweight 9. The counterweight 9 is vertically lifted and lowered along the counterweight guide rail 20.

[0035] In some embodiments, as Figure 6-7 As shown, compartment doors 15 are provided at both ends of the said compartments 7 and 8.

[0036] In some embodiments, as Figure 6-12As shown, U-shaped sealing frames 14 are provided at both ends of the ship-carrying chamber 7, and a U-shaped sealing frame 14 is provided at one end of the ship-carrying chamber 8 close to the downstream side. Under the push of the driving cylinder 18, the end water-stop rubbers 21 of the U-shaped sealing frames 14 at both ends of the ship-carrying chamber 7 are respectively pressed against the upper gate working door 1 and the stainless steel vertical water-stop panel 22 at the end of the ship-carrying chamber 8, forming a gap sealing space connecting the end of the ship-carrying chamber 7 with the upper gate working door 1 and the end of the ship-carrying chamber 8. Under the push of the driving cylinder 18, the end water-stop rubber 21 of the U-shaped sealing frame 14 on the downstream side of the ship-carrying chamber 8 is docked with the stainless steel vertical water-stop panel 22 of the lower gate working door 3, forming a gap sealing space connecting the end of the ship-carrying chamber 8 with the lower gate working door 3.

[0037] Working principle of the present invention:

[0038] When two ship lifts on a certain ship lift route are operating simultaneously, taking the downward movement of the ship carriage as an example, the ship carriage 7 is in a docking state with the upper gate working door 1, and the water area of ​​the ship carriage 7 is connected to the water area of ​​the upstream pilot channel. At this time, the cabin doors 15 at both ends of the ship carriage 7, the upstream cabin door 15 of the ship carriage 8 and the upper gate working door 1 are all open, and the U-shaped sealing frames 14 at both ends of the ship carriage 7 are docked with the upper gate working door 1 and the ship carriage 8 respectively, and the downstream cabin door 15 of the ship carriage 8 is in the closed position. After untying the cable from the upstream pilot channel berth, the two ships go down and enter the ship carriage 7 and the ship carriage 8 in turn, then moor and tie up. Close the upper gate working door 1, and at the same time close the cabin doors 15 of the ship carriages (7, 8), and retract the U-shaped sealing frames 14. Start the driving mechanism to drive the two ship carriages (7, 8) to move downward. When the ship-carrying compartments (7, 8) descend to the set elevation, the downstream U-shaped sealing frame 14 of the ship-carrying compartment 7 is pushed out to dock with the ship-carrying compartment 8, the downstream U-shaped sealing frame 14 of the ship-carrying compartment 8 is pushed out to dock with the lower lock head working door 3, the downstream side cabin door 15 of the ship-carrying compartment 7, the cabin doors 15 at both ends of the ship-carrying compartment 8 and the lower lock head working door 3 are opened, and the vessel casts off the cabin and sails into the downstream pilot channel.

[0039] When a single-seat ship lift on a certain ship lift route is in operation, taking the downward movement of the ship carriage as an example, the ship carriage 7 is in a docking state with the upper lock head, and the ship carriage water area is connected with the upstream pilot channel water area. At this time, the cabin doors 15 at both ends of the ship carriage 7, the upstream cabin door 15 of the ship carriage 8 and the upper lock head working door 1 are all open, and the U-shaped sealing frames 14 at both ends of the ship carriage 7 are docked with the upper lock head working door 1 and the ship carriage 8 respectively, and the downstream cabin door 15 of the ship carriage 8 is in the closed position. A ship unties from the berth at the upstream pilot channel, then sails down into the ship carriage 8, moors and ties up. Close the upper lock head working door 1, and at the same time close the cabin doors 15 of the ship carriages (7, 8), and retract the U-shaped sealing frame 14. Start the driving mechanism to drive the ship carriage 8 to move downward. When the ship-carrying compartment 8 descends to the set elevation, the downstream U-shaped sealing frame 14 of the ship-carrying compartment 8 is pushed out to dock with the lower gate working door 3, the downstream compartment door 15 of the ship-carrying compartment 8 and the lower gate working door 3 are opened, and the vessel casts off from the compartment and enters the downstream pilot channel.
