Description

Technical Field

[0001] The invention relates to a ship lift, in particular to a hump-type bidirectional inclined ship lift, belonging to the technical field of ships passing through auxiliary facilities of high dams. Background Art

[0002] The hump-type inclined ship lift is a device for ships to pass through dams with high water level differences. It has the advantage of utilizing natural terrain to reduce the cost of civil engineering projects. The hump-type inclined ship lift usually has a turntable at the top of the peak to adjust the direction of the ship carriage to adapt the ship carriage from traveling uphill to traveling downhill. At present, the hump-type inclined ship lift is rarely used. The main reasons include the following problems: First, when the ship carriage changes from uphill to downhill, it needs to change direction at the top of the peak, which increases the time for ships to pass the dam and the project investment. Second, the ship carriage needs to travel between the upstream and downstream of the dam. Affected by the layout of the inclined ship lift, it is impossible to arrange a counterweight to balance the gravity of the ship carriage and the ship like a vertical ship lift. The gravity of the ship carriage and the ship is driven by electricity, and the inclined ship lift consumes huge energy in operation. Third, the smaller the slope of the inclined ship lift, the smaller the lifting force required. Usually, the more economical slope ratio is between 1:10 and 1:12. That is to say, the farther the original slope ratio deviates from this range, the greater the project investment, which limits the economic application range of the inclined ship lift. Fourth, both the inclined ship lift and the vertical ship lift travel back and forth between upstream and downstream, and can only transport ships in one direction at a time. The ship lift cannot transport upstream ships to downstream while transporting downstream ships to upstream, and vice versa, resulting in low operating efficiency of the ship lift.

[0003] In order to solve the problem of the ship-carrying compartment of the inclined ship lift changing direction at the peak, the Chinese patent document with the publication number CN106930263A discloses a dry and wet dual-transport inclined ship lift with high and low wheels. The high and low wheels avoid the problem of the traditional inclined ship lift setting a turntable on the top of the dam to achieve the ship-carrying compartment changing direction. However, this scheme is a one-way transport, and only ships in one direction can pass at a time, and the operation efficiency of the ship lift is low; and in this scheme, the center lines of the upstream and downstream tracks must be on the same plane, and there must be no horizontal angles, which puts high requirements on the layout site.

[0004] In order to improve the operating efficiency of the inclined ship lift, the Chinese patent document with the publication number CN104404938A discloses a bidirectional inclined ship lift, which arranges two sets of tracks and ship carriages in parallel to achieve bidirectional transportation. Although this solution is bidirectional transportation, the parallel arrangement not only puts high requirements on the layout site, but also greatly increases the project investment.

[0005] In addition, all loads in the ship-bearing compartment of the existing inclined ship lift are pulled by electricity, which consumes huge energy. In order to reduce energy consumption, the slope of the inclined plane is set as gentle as possible, which leads to an increase in the amount of civil engineering work. Summary of the invention

[0039] Beneficial effects:

[0040] (1) In the hump-type bidirectional inclined ship lift of the present invention, by independently arranging the upstream and downstream two sets of ship-carrying boxes, the inclined ship lift can be arranged according to the actual terrain (that is, the horizontal turning angle of the center line of the upstream and downstream tracks can be designed according to the terrain), thereby reducing the amount of excavation and backfilling earthwork and reducing the project investment; and the middle channel can transport two ships at the same time, thereby enabling the upstream and downstream ship-carrying boxes to transport ships at the same time, thereby improving the operating efficiency of the inclined ship lift; the bidirectional inclined ship lift not only realizes the bidirectional operation of the ship lift, but also can be arranged according to the actual terrain, with minimal restrictions on the slope gradient, thereby greatly reducing the project cost.

DETAILED DESCRIPTION

[0054] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0055] Embodiment 1:

[0056] This embodiment provides a hump-type bidirectional inclined ship lift, which is arranged according to the actual terrain, thereby improving the operating efficiency of the inclined ship lift and reducing the operating energy consumption of the inclined ship lift; the ship lift is a hump-type dry and wet dual-transport ship lift mainly suitable for natural slope terrain on both sides of a high dam.

[0057] like Figure 1 and Figure 2 As shown, the hump-type bidirectional inclined ship lift includes: an upstream inclined ship lift 1, an intermediate channel 2 and a downstream inclined ship lift 3. The upstream inclined ship lift 1 and the downstream inclined ship lift 3 are connected through the intermediate channel 2; the upstream inclined ship lift 1 is used to transport upstream ships or downstream ships traveling through the intermediate channel 2, and the downstream inclined ship lift 3 is used to transport downstream ships or upstream ships traveling through the intermediate channel 2; while the upstream inclined ship lift 1 transports the upstream ship to the intermediate channel 2, the downstream inclined ship lift 3 transports the downstream ship to the intermediate channel 2; the upstream ship enters the downstream inclined ship lift 3 through the intermediate channel 2 and is then transported to the downstream; at the same time, the downstream ship enters the upstream inclined ship lift 1 through the intermediate channel 2 and is then transported to the upstream; the intermediate channel 2 can simultaneously drive two ships in parallel; thereby, the synchronous transportation of upstream and downstream ships can be achieved, and the transportation efficiency is doubled.

[0058] like Figure 3As shown, the upstream inclined ship lift 1 includes: an upstream ship carrier assembly 4, a ship carrier track 7, a lifting unit, a brake 13 and a counterweight unit; wherein the counterweight unit is used to balance the weight of the upstream ship carrier assembly 4 and the water body and the ship 6 it carries, so as to achieve a balance in the lifting force of the ship carrier and reduce the energy consumption of the inclined ship lift; the ship carrier track 7 is connected to the middle channel 2, and the upstream ship carrier assembly 4 can move along the ship carrier track 7 under the drive of the lifting unit, so that the upstream ship carrier assembly 4 is docked with the middle channel 2, and then the ship 6 in the upstream ship carrier assembly 4 enters the middle channel 2. The operation of the upstream ship carrier assembly 4 is driven by the driving unit in the lifting unit to overcome the unbalanced loads such as wind load and friction during the operation.

[0059] Specific: such as Figure 4 As shown, the upstream ship carrier assembly 4 includes: a ship carrier structure 22, a ship carrier frame 21, a ship carrier working door and a U-shaped water seal 20; the ship carrier structure 22 is arranged on the ship carrier frame 21, and supported on the ship carrier track 7 through the ship carrier frame 21, and the ship carrier frame 21 can move along the ship carrier track 7 under the action of the lifting unit; the U-shaped water seal 20 is arranged at the end of the ship carrier structure 22 close to the middle channel 2, and is used for sealing and docking with the upstream end of the middle channel 2. The end of the ship carrier structure 22 close to the middle channel 2 extends out of the ship carrier frame 21 on both sides (i.e., has a lateral extension on both sides), which is used to connect the lifting unit and the counterweight unit.

[0060] A cleaning device 8 is provided at the end of the ship-carrying compartment structure 22 away from the middle channel 2. When the upstream ship-carrying compartment assembly 4 completes the transportation task of the ship 6 and moves back, the cleaning device 8 can clean the silt on the ship-carrying compartment track 7 and its surroundings.

[0061] The lifting unit is used to lift the upstream ship carrier assembly 4 so that it can move along the ship carrier track 7. As an example, two sets of lifting units are provided, and the two sets of lifting units are respectively arranged on the lateral sides of the end where the middle channel 2 is connected to the upstream inclined ship lift 1.

[0062] The lifting unit includes: a power unit, a lifting drum 14 and a lifting wire rope 11; the power unit is used to drive the lifting drum 14 to rotate around its own axis; one end of the lifting wire rope 11 is wound around the lifting drum 14, and the other end is connected to the lateral extension of the corresponding side of the ship-carrying box structure 22. As an example, the power unit includes a motor 16 and a reducer 15; the motor 16 drives the lifting drum 14 through the reducer 15, and the lifting drum 14 rotates to release or recycle the lifting wire rope 11, thereby driving the upstream ship-carrying box assembly 4 to move along the ship-carrying box track 7.

[0063] In order to brake the lifting drum 14 and keep the upstream ship carrier assembly 4 at a set position (especially braking when the upstream ship carrier assembly 4 is docked with the middle channel 2 ), a brake 13 is provided on the lifting drum 14 .

[0064] In addition, if Figure 3 As shown, the ship carriage working door in the upstream ship carriage assembly 4 includes: an upstream ship carriage working door 9 arranged upstream of the ship carriage structure 22 (i.e., away from the end of the middle channel 2) and an intermediate channel working door 10 of the ship carriage arranged at the end of the ship carriage structure 22 close to the middle channel 2; by closing the upstream ship carriage working door 9 and the intermediate channel working door 10 of the ship carriage, a closed space for transporting ships 6 is formed inside the ship carriage structure 22.

[0065] The structure and composition of the downstream inclined ship lift 3 are the same as those of the upstream inclined ship lift 1 , and the ship carriage assembly in the downstream inclined ship lift 3 is the downstream ship carriage assembly 23 .

[0066] The upstream inclined ship lift 1 and the downstream inclined ship lift 3 are arranged independently (i.e., the upstream and downstream two sets of ship carrying compartments are arranged independently). Thus, the upstream inclined ship lift 1 and the downstream inclined ship lift 3 can be arranged separately according to the actual terrain, i.e., the slope gradient and the longitudinal centerline horizontal turning angle of the upstream inclined ship lift 1 and the downstream inclined ship lift 3 can be designed according to the actual terrain.

[0067] The longitudinal ends of the middle channel 2 are connected to the upstream inclined ship lift 1 and the downstream inclined ship lift 3. By connecting the upstream inclined ship lift 1 and the downstream inclined ship lift 3 through the middle channel 2, the upstream and downstream ship carrying compartments can simultaneously transport ships 6, thereby improving the operating efficiency of the inclined ship lift.

[0068] Intermediate channel working doors are arranged at both longitudinal ends of the intermediate channel 2, namely the intermediate channel upstream working door 121 and the intermediate channel downstream working door 122; the intermediate channel upstream working door 121 and the intermediate channel downstream working door 122 are normally closed doors, which can only be opened after the ship-carrying compartment structure 22 of the upstream inclined ship lift 1 or the downstream inclined ship lift 3 is sealed and connected with the intermediate channel 2.

[0069] A U-shaped water stop plate 19 is pre-embedded in the concrete structure adjacent to the working door of the middle channel (that is, water stop plates are pre-embedded in the concrete structure on both sides and the bottom of the outer sides of the two ends of the middle channel 2 around the upstream working door 121 and the downstream working door 122 of the middle channel, forming a U-shaped water stop plate 19); when the upstream ship carrier assembly 4 or the downstream ship carrier assembly 23 climbs along the ship carrier track 7 to dock with the middle channel 2, the U-shaped water seal 20 on the ship carrier structure 22 is docked and compressed with the U-shaped water stop plate 19 at the end of the middle channel 2 to ensure the sealing of the docking point, so as to avoid water leakage between the upstream ship carrier assembly 4 or the downstream ship carrier assembly 23 and the middle channel 2 during docking.

[0070] The width of the two ends of the middle channel 2 is consistent with the inner net width of the corresponding side bearing compartment structure 22 (to minimize the size of the sealing docking and ensure the reliability of the sealing; at the same time, space is left for the arrangement of the lifting unit and the counterweight unit, that is, the lifting unit and the counterweight unit are arranged on both sides of the end of the middle channel 2 in this solution); the width and length of the middle part meet the requirements for two ships of the maximum size in the current river to sail in parallel. The water level in the middle channel 2 is kept consistent with the water depth of the upstream and downstream bearing compartment assemblies (that is, the water depth in the bearing compartment structure 22 of the upstream bearing compartment assembly 4 and the downstream bearing compartment assembly 23).

[0071] As an example, a limit plate is also provided at the docking end of the ship carriage track 7 and the middle channel 2 to limit the travel of the ship carriage frame 21, while keeping the U-shaped water seal 20 in an optimal compression state, to ensure that there is no water leakage when the upstream inclined ship lift 1 is docked with the middle channel 2, and the U-shaped water seal 20 is not damaged due to excessive compression force.

[0072] Embodiment 2:

[0073] On the basis of the above-mentioned embodiment 1, this embodiment provides a specific implementation method of the counterweight unit; the counterweight unit in this embodiment is a slope balancing unit.

[0074] Take the counterweight unit installed on the upstream inclined ship lift 1 as an example. Figure 3 As shown, there are two counterweight units, which are respectively arranged on the lateral sides of the upstream ship supporting box assembly 4 (that is, two counterweight units are arranged in the upstream inclined ship lift 1, and two counterweight units are arranged in the downstream inclined ship lift 3, and the two counterweight units in the downstream inclined ship lift 3 are respectively arranged on the lateral sides of the downstream ship supporting box assembly 23).

[0075] The counterweight unit is arranged outside the corresponding end lifting unit; it includes: counterweight 5, counterweight roller 30, counterweight fixed pulley 29, counterweight track 28 and counterweight wire rope 24. The counterweight fixed pulley 29 is arranged outside the lifting drum 14 in the lifting unit; one end of the counterweight wire rope 24 is connected to the counterweight 5, and the other end passes through the counterweight fixed pulley 29 and is reversely connected to the end of the ship-carrying box structure 22 close to the corresponding side of the middle channel 2, that is, the outside of the connection of the lifting wire rope 11 on the lateral extension of the ship-carrying box structure 22.

[0076] The counterweight tracks 28 in the two counterweight units are symmetrically arranged on the slopes on both sides of the ship-carrying box track 7, and the arrangement plane of the counterweight tracks 28 is parallel to and lower than the arrangement plane of the ship-carrying box track 7. The counterweight 5 is supported on the counterweight tracks 28 by the counterweight rollers 30 and can move along the counterweight tracks 28; the counterweight 5 is arranged under the ship-carrying box structure 22 parallel to the upper surface of the slope, and the counterweight 5 does not collide with the ship-carrying box structure 22 when it moves under both sides of the ship-carrying box structure 22.

[0077] Embodiment 3:

[0078] On the basis of the above-mentioned embodiment 1, further, this embodiment provides another specific implementation of the counterweight unit; the counterweight unit in this embodiment is a vertical balancing unit, and the structure of the bidirectional inclined ship lift equipped with the vertical balancing unit is as follows: Figure 5-Figure 7 shown.

[0079] Taking the counterweight unit arranged on the upstream inclined ship lift 1 as an example, in the present embodiment, there are two counterweight units, which are arranged on the lateral sides of the docking end between the middle channel 2 and the upstream ship supporting box assembly 4 (that is, two counterweight units are arranged in the upstream inclined ship lift 1, and two counterweight units are arranged in the downstream inclined ship lift 3; the two counterweight units of the downstream inclined ship lift 3 are arranged on the lateral sides of the docking end between the middle channel 2 and the downstream ship supporting box assembly 23).

[0080] The counterweight unit in this embodiment includes: a counterweight 5 and a counterweight steel wire rope 24. A counterweight shaft 31 is provided below both lateral sides of the middle channel 2 and the upstream ship-carrying compartment assembly 4. The counterweight 5 is arranged in the counterweight shaft. One end of the counterweight steel wire rope 24 is connected to the counterweight 5, and the other end is wound around the lifting drum 14 on the corresponding side. The winding direction of the counterweight steel wire rope 24 on the lifting drum 14 is opposite to the winding direction of the lifting steel wire rope 11 on the lifting drum 14. Therefore, when the lifting drum 14 retracts the lifting steel wire rope 11 to lift the upstream ship-carrying compartment assembly 4, the counterweight 5 is released downward through the counterweight steel wire rope 24.

[0081] Embodiment 4:

[0082] On the basis of the above-mentioned embodiments 1 to 3, further, a water delivery and drainage unit is included.

[0083] A water delivery and drainage unit is arranged near the upstream inclined ship lift 1 of the middle channel 2, and the water delivery and drainage unit includes: a lifting pump 17, an electric valve 18, a lower water delivery pipe 25, an upper water delivery pipe 26 and a drainage pipe 27. The two ends of the lifting pump 17 are respectively connected to the lower water delivery pipe 25 and the upper water delivery pipe 26, the other end of the lower water delivery pipe 25 is arranged below the lowest navigable water level in the upstream, and the other end of the upper water delivery pipe 26 is arranged at the navigable water level of the middle channel 2. The two ends of the drainage pipe 27 are respectively connected to the lower water delivery pipe 25 and the upper water delivery pipe 26, and the electric valve 18 is arranged in the middle of the drainage pipe 27, and the electric valve 18 is in a normally open state. When the water level of the middle channel 2 is higher than the navigable water level due to rainfall or other reasons, the water in the middle channel 2 is discharged upstream through the upper water delivery pipe 26, the drainage pipe 27 and the lower water delivery pipe 25 in sequence until the water level of the middle channel 2 drops to the navigable water level (the lifting pump 17 is not started in this process). When it is detected that the water level of the middle channel 2 is lower than the navigation level, the electric valve 18 is closed, the lifting pump 17 is started, and the upstream water is input into the middle channel 2 through the lower water pipe 25 and the upper water pipe 26 until the water level of the middle channel 2 rises to the navigation level.

[0084] The above-mentioned navigable water level is the water level in the ship-carrying compartment structure 22 of the upstream ship-carrying compartment assembly 4 .

[0085] Although the present invention has been described in detail above by general description and specific embodiments, it is obvious to those skilled in the art that some modifications or improvements can be made on the basis of the present invention. Therefore, these modifications or improvements made on the basis of not departing from the spirit of the present invention all belong to the scope of protection claimed by the present invention.
