Description

Technical Field

[0001] The invention belongs to the field of navigation buildings in water conservancy and hydropower engineering, and in particular relates to an inclined ship-carrying compartment transportation system. Background Art

[0002] A ship lift is a common navigation structure, also known as a "ship lift". Its principle is to use a mechanical device to lift and lower passing ships to overcome the concentrated water level difference on the waterway. A ship lift saves water or consumes almost no water compared to a lock, and plays a huge role in rivers with little water or artificial canals.

[0003] Ship lifts are generally divided into two types: vertical and inclined. Compared with vertical ship lifts, inclined ship lifts are easier to manage and maintain, avoiding the complex technical difficulties and operational problems caused by high-altitude buildings. However, the ship compartment on the traditional inclined ship lift is inconvenient for loading and unloading ships, and when the inclined ship lift changes speed, it will affect the stability of the ship in the ship compartment, bringing some safety hazards. When the ship deviates slightly, due to inaccurate manual detection, the best adjustment time is wasted, ultimately causing economic losses and casualties of operators. Summary of the invention

[0004] In view of the defects and problems existing in the existing ship holding chamber, the present invention provides an inclined ship holding chamber transportation system, which can realize automatic loading and unloading of ships, and can adsorb and fix the hull to the bottom plate of the transportation device, thereby increasing the stability of the ship in the ship holding chamber. A monitoring device is arranged on the transportation device to monitor the position of the ship in real time.

[0005] The solution adopted by the present invention to solve its technical problems is: an inclined ship-carrying box transportation system, including a transportation area located between an upstream upper lock head and a downstream lower lock head, the ground of the transportation area is built with an inclined surface and an inclined track is laid flat, a ship-carrying box is placed on the inclined track, a driving mechanism and a transmission mechanism for driving the ship-carrying box to move along the inclined surface are provided, a box frame is connected downwardly to the bottom of the ship-carrying box, the bottom surface of the box frame is an inclined surface consistent with the inclined surface of the transportation area, the track wheel installed at the bottom of the box frame is assembled with the inclined track, the top surface of the box frame is a plane and connected to the bottom of the ship-carrying box; four top corner positions on the upper side of the ship-carrying box are vertically fixed with columns, and the upper ends of the columns are fixedly installed with rotating A lifting device, wherein the rotating lifting device includes a slewing mechanism, on which a telescopic boom, a lifting rope and a hook are provided. A pair of hooks of the rotating lifting device located at the front end of the ship-carrying chamber simultaneously lift the lifting positions on both sides of the ship to move the ship from the upstream water level into the ship-carrying chamber, and a pair of hooks of the rotating lifting device located at the rear end of the ship-carrying chamber simultaneously lift the lifting positions on both sides of the ship to move the ship from the ship-carrying chamber to the downstream water level; slide rails are vertically provided on the inner sides of the left and right side walls of the ship-carrying chamber respectively, and horizontal sliding bars are installed on each of the sliding rails on each side, and a mechanism for driving the horizontal sliding bars to rise and fall is provided, and sensors for monitoring the side distance of the ship are evenly distributed on the horizontal sliding bars.

[0006] A parking area is divided into a plurality of parking spaces in the middle of the ship receiving compartment. Two longitudinally symmetrical grooves are provided in the middle of the parking spaces. There are also grooves between adjacent parking spaces. A plurality of suction cup fixing devices are evenly fixed in the grooves. When a ship is parked at the parking space, the suction cup fixing devices on the parking space will be adsorbed on the bottom of the ship to fix the ship.

[0007] The upper end of the suction cup fixing device in the groove protrudes out of the groove.

[0008] The rotating hoisting device and the sensor are connected to a control panel arranged on the ship-carrying compartment via a PLC controller to form a transport monitoring device for the ship body.

[0009] The parking area is arranged between the rotating lifting devices at the four top corners of the ship-carrying compartment, and the extension limit length of the telescopic boom on the rotating lifting device is not less than the length of the parking area.

[0010] The length of the sliding bar is the same as the length of the parking area.

[0011] The telescopic column is always in an outwardly extended state. When a ship is parked in the ship-carrying compartment, the bottom of the ship squeezes the lower fixed shell of the suction cup to cause the telescopic column to shrink into the groove.

[0012] Beneficial effects of the present invention:

[0013] The inclined ship-carrying box transportation system provided by the present invention is provided with a lifting device and a sensor in the ship-carrying box, and is connected with the control panel on the ship-carrying box through a PCL controller to form a transportation monitoring device of the ship.

[0014] The inclined ship holding compartment transportation system provided by the present invention is convenient for parking ships, and the stability of the ship in the ship holding compartment is increased by arranging a fixing device. When the ship is displaced in the ship holding compartment, the sensor will send an alarm to the control panel through the PLC controller, instructing the staff to stop the ship holding compartment and check the fixing device.

DETAILED DESCRIPTION

[0026] The present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0027] Example 1

[0028] A kind of Figure 1 The inclined transport system for upstream and downstream transport of ships shown in FIG. Figure 2 and Figure 3 See the trolley box shown. Figure 1 The ship-carrying compartment is located in the transport area between the upstream upper lock head 7 and the downstream lower lock head 8. The transport area is a slope built on the upper surface of the dam body and a slope track 31 is laid flat. The heights of the upstream upper lock head 7 and the downstream lower lock head 8 are both higher than the transport area.

[0029] A carriage frame 9 is arranged on the inclined track 31. The bottom surface of the carriage frame 9 is an inclined surface consistent with the inclined surface of the transport area. A track wheel 30 is installed at the bottom of the carriage frame 9 and is assembled with the inclined track 31. A guide wheel, such as a guide rope wheel, is arranged at the top or bottom of the inclined track 31. A traction steel rope is wrapped around the upper and lower guide rope wheels. A winch is arranged to drive the steel rope to operate. At the same time, the steel rope is fixedly connected to the bottom of the carriage frame 9 (between the two side tracks). When the winch rotates, it can pull the carriage frame 9 up and down along the inclined track 31 through the steel rope.

[0030] The top surface of the carriage frame 9 is a plane, and the top of the carriage frame 9 is longitudinally fixedly connected as shown in FIG. Figure 2 The carrier compartment 1 is shown.

[0031] like Figure 2 and Figure 3In the embodiment, fixed columns 2 are vertically fixed at the four top corners on the upper side of the ship compartment 1, and a rotating lifting device is fixedly installed on the upper end of the fixed columns 2. The rotating lifting device can adopt the rotating lifting device currently used for cranes. The existing rotating lifting device is not described in detail, but in this embodiment, the rotating lifting device that can also be used includes a slewing mechanism, and the slewing mechanism includes a slewing table 32 arranged at the upper end of the column. The slewing table 32 can be driven to rotate according to control requirements by a slewing drive mechanism, and the slewing drive mechanism includes a slewing motor and a corresponding gearbox. A hanger body 3 is arranged on the slewing table. Among them, the hanger body also adopts the existing crane hanger. For example, using Figure 1 The hydraulic telescopic boom 4 shown in the figure has a pulley block mechanism at the end thereof, the pulley block mechanism comprises a fixed pulley rotatably arranged at the upper end of the boom, the fixed pulley is connected to the movable pulley through a lifting rope 5, a hook 10 is fixedly arranged on the movable pulley, and an electric winch is arranged on the hanger body 3, the electric winch can be controlled to pull and retract the lifting rope, and the hook is driven to move vertically by the rotation of the fixed pulley block and the movable pulley block.

[0032] When lifting the ship 6, it is necessary to make the rotating lifting devices at the two top corners of the front end (or rear end) of the ship-carrying compartment 1 perform lifting operations on the lifting positions (at least four symmetrical points on both sides) symmetrically arranged on both sides of the ship 6 at the same time, so that the ship can be more stable when moving in the air.

[0033] For example, when there is a ship 6 that needs to be lifted upstream, the hooks 10 of a pair of rotating lifting devices located at the front end of the ship holding chamber 1 simultaneously lift the lifting positions on both sides of the ship, and move the ship 6 from the upstream water level to the ship holding chamber 1, and the hooks 10 of a pair of rotating lifting devices located at the rear end of the ship holding chamber 1 simultaneously lift the lifting positions on both sides of the ship 6, and move the ship 6 from the ship holding chamber 1 to the downstream water level.

[0034] like Figure 2 As shown, ship-carrying monitoring devices are provided on the inner walls on the left and right sides of the ship-carrying chamber 1, and the ship-carrying monitoring devices include a vertical slide rail group and a transverse horizontal slide bar 12. The slide rail group includes two slide rails 11 fixed on the inner wall of the ship-carrying chamber 1 at intervals, and electric sliders are provided in the middle of the left and right ends of the horizontal slide bar 12. The electric sliders are correspondingly nested in the slide rails 11 and can slide synchronously up and down along the slide rails 11. Sensors 13 for monitoring the side distance of the ship are evenly distributed on the horizontal slide bar 12.

[0035] Limit blocks 14 are symmetrically provided at the upper and lower ends of the slide rail 11, and the upper limit block 14 prevents the electric slider from sliding out of the slide rail 11; the height of the limit block 14 is a, and the height of the horizontal slide bar 12 is b, wherein a>½b, to prevent the electric slider from driving the horizontal slide bar 12 to move downward along the slide rail 11, thereby preventing the horizontal slide bar 12 from colliding with the bottom of the passenger compartment 1 and damaging the sensor 13 on the horizontal slide bar 12.

[0036] like Figure 3 , Figure 5 As shown, a parking area is provided at the bottom of the ship-carrying compartment 1 between the rotating lifting devices at the four corners, and the length of the horizontal sliding bar is the same as the length of the parking area, so that the monitoring range of the sensor 13 on the horizontal sliding bar covers the entire parking area, thereby realizing high-precision monitoring; the parking area is evenly divided into four parking spaces, and the extension limit length of the hydraulic telescopic boom 4 on the rotating lifting device is not less than the length of the parking area, so that the rotating lifting device can lift the ship to any parking space.

[0037] The slewing mechanism of the rotary lifting device, the hydraulic mechanism of the hydraulic telescopic boom 4, the electric winch and the electric slider and sensor 13 of the ship-carrying monitoring device are all connected to the control panel arranged on the upper side of the ship-carrying device through the PLC controller to form a hull transportation monitoring device.

[0038] like Figure 4 , Figure 8 As shown, when a single ship 6 is to be hoisted outside the upper lock head 7 and placed in the boat cabin 1, the rotary lifting device a20 and the rotary lifting device b21 at the two top corners of the front end of the boat cabin 1 are firstly controlled to rotate the ends of the hydraulic telescopic boom 4 respectively and extend to the corresponding hoisting position of the ship 6, and the length of the hoisting rope 5 is controlled by the rotary lifting device pulley mechanism, so that the hooks 10 on the rotary lifting device a20 and the rotary lifting device b21 are respectively fixed on the hoisting position of the ship, and then the single ship mode on the control panel is selected, and then the loading start on the control panel is selected. The PLC controller will first synchronously control the lifting device a20 and the rotary lifting device b21. The slewing mechanism on the lifting device b21 collects the lifting rope 5, and after the ship 6 rises stably to a safe height, the PLC controller controls the slewing mechanism and the hydraulic telescopic boom 4 of the lifting device a20 and the rotating lifting device b21 to operate. When the rotating body 3 on the rotating lifting device a20 rotates clockwise on the turntable 32, the rotating body 3 on the rotating lifting device b21 rotates counterclockwise on the turntable 32. While the rotating body 3 rotates, the hydraulic telescopic boom 4 on the lifting device a20 and the rotating lifting device b21 also shrink synchronously. During this process, the ship 6 will move horizontally and longitudinally above the middle of the cabin 1 along the transportation centerline 35.

[0039] When the ship 6 moves to position B, the rotating lifting bodies 3 on the rotating lifting devices a20 and b21 continue to rotate. At this time, the hydraulic telescopic booms 4 on the lifting devices a20 and b21 stop contracting and extend. At this time, the ship continues to move horizontally and longitudinally toward the upper middle of the passenger compartment 1.

[0040] When the ship 6 moves to position C, the PLC controller stops controlling the slewing mechanism and the hydraulic telescopic boom on the rotating lifting device a20 and the rotating lifting device b21, and switches to synchronously controlling the pulley mechanism on the rotating lifting device a20 and the rotating lifting device b21, so that the ship 6 can be steadily lowered to the parking area in the middle of the passenger compartment 1.

[0041] After the vessel 6 is hoisted and lowered, the winch at the top of the inclined track 31 is started, and the carriage frame 9 moves along the inclined track 30 toward the lower gate head according to the rope-releasing speed of the winch.

[0042] If the ship 6 in the passenger compartment 1 is displaced during transportation, the sensor 12 in the passenger compartment 1 will send an alarm to the control panel through the PLC controller, instructing the staff to stop the winch to stop the movement of the carrier frame 9, check the ship 6 in the passenger compartment 1, and start the winch to continue moving the carrier frame 9 after the alarm is lifted.

[0043] Example 2

[0044] like Figure 5 , Figure 8 As shown, when the ship 6 needs to be parked at other berthing positions in the ship holding chamber 1 after being hoisted from upstream, the PLC controller will change the retraction or extension speed of the hydraulic telescopic arm 4 of the rotating hoisting device at the two top angle positions without changing the rotation speed of the rotating hoisting device at the two top angle positions at the front end of the ship holding chamber, so that the ship 6 can be parked stably at the designated berthing position.

[0045] Example 3

[0046] The difference between embodiment 3 and embodiment 1 is that a fixing device is provided in the parking area of ​​the passenger compartment.

[0047] like Fig. 9 As shown, a parking area is divided in the middle of the ship-carrying compartment, and the parking area is evenly divided into a plurality of parking spaces. Two grooves are longitudinally and symmetrically opened in the middle of the parking spaces, and grooves 33 are also opened between adjacent parking spaces. A plurality of suction cup fixing devices 34 are evenly arranged in the grooves.

[0048] like Figure 7As shown, the suction cup fixing device 34 includes a fixing column 26 with a lifting groove in the middle upper section, a retaining ring 18 is fixed to the upper end surface of the fixing column 26 by bolts, a lifting column 27 is set in the lifting groove, the bottom of the lifting column 27 is fixedly connected to the bottom of the lifting groove by a support spring 15, the retaining ring 18 prevents the lifting column 27 from being pushed out of the lifting groove by the support spring 15, the upper end of the lifting column 27 extends out of the retaining ring 18 and is fixedly provided with a hemispherical support shell 16 with an opening facing outward, and a sealing ring is provided between the retaining ring 18 and the lifting column 27 25, an L-shaped exhaust passage 28 penetrating the supporting shell 16 and the circumferential side of the lifting column is provided in the middle of the lifting column 27 outside the lifting slot, a suction cup 17 is provided in a sealed fixed sleeve inside the supporting shell 16, the upper end surface of the suction cup 19 extends outward and covers the upper end surface of the supporting shell 16, an exhaust hole is provided in the middle of the suction cup 17 and is connected with the exhaust passage 28, an exhaust hole 29 penetrating the lifting slot is axially provided on the circumferential side wall of the upper end of the fixed column 26, the exhaust hole 29 is connected to an exhaust pump through an exhaust pipe, and a negative pressure state is always maintained in the lifting slot.

[0049] The suction cup fixing device is vertically fixed to the bottom of the groove 33, the support shell 16 and the suction cup 19 at the upper end of the suction cup fixing device protrude from the groove 33, the length of the upper end surface of the suction cup 19 protruding from the groove 33 is a, and the vertical distance between the exhaust channel opening on the circumferential side of the lifting column of the suction cup fixing device in the un-pressed state and the exhaust hole 29 on the fixing column is b, where a=b.

[0050] like Fig.10 As shown, when the rotary lifting device parks the ship at the parking position, the bottom of the ship 6 will squeeze the suction cup fixing device of the protruding groove 33 into the groove. At this time, the suction cup 19 is in close contact with the bottom of the ship 6, and the exhaust channel opening on the circumferential side of the lifting column 27 is squeezed into the lifting groove. At this time, the suction cup is connected with the lifting groove through the exhaust channel 18. Through the continuous exhaust of the exhaust pump, a negative pressure is reached between the suction cup and the bottom of the hull, so that the suction cup is fixed to the bottom of the ship 6. At this time, since the suction cup fixing device on the parking position is adsorbed on the bottom of the ship 6, the stability of the ship during transportation is increased.
