Description

Technical Field

[0001] The invention belongs to the technical field of elevators, and in particular relates to a lifting device for ships. Background Art

[0002] The most common types of passenger ships in shallow waters, rivers and lakes are small passenger ships with a capacity of four to seven people. When this type of passenger ship reaches the specified time or a malfunction occurs, it is necessary to pull the small passenger ship into the dock, adjust it to the corresponding maintenance station via a lift, and then lift it up for inspection and maintenance.

[0003] In the prior art, when a ship is lifted from the water, it needs to be lifted by a gantry crane or a large crane. In this process, people need to go into the water, fix the ship and the elevator with steel cables, and then lift it. The whole process is cumbersome and inefficient. After lifting, it is transferred to the maintenance position and lifted by the elevator for maintenance and repair. In this way, an additional elevator needs to be set up at the corresponding maintenance position, and the ship needs to be repeatedly fixed, which is inefficient and has high equipment costs. Summary of the invention

[0004] The technical problem to be solved by the present invention is to overcome the disadvantages of the above-mentioned prior art and provide an integrated ship lifting device.

[0005] The technical solution adopted to solve the above technical problems is: a ship lifting device, including two symmetrically arranged transfer rails, and a ship underwater lifting mechanism for lifting the ship from the water is slidably connected between the two transfer rails.

[0006] Through the above technical solution, the transfer rails support the underwater lifting mechanism of the ship and guide its moving direction, and the small passenger ship is squeezed and lifted by the underwater lifting mechanism of the ship.

[0007] A maintenance lifting mechanism for lifting a ship is fixedly connected to the lower surface of one end of the two transfer rails located on the shore, and a transfer control mechanism is fixedly connected to one end of the two transfer rails close to the maintenance lifting mechanism.

[0008] Through the above technical scheme, the maintenance lifting mechanism can lift the small passenger ship transferred by the ship's underwater lifting mechanism, making it convenient for the staff to inspect the bottom of the ship. The transfer control mechanism drags the ship to the maintenance station and controls it to lift it up. The transfer rail is higher on the side close to the maintenance lifting mechanism and lower on the side away from the maintenance lifting mechanism. The higher and lower positions are arranged in a gentle slope, which is convenient for towing the ship ashore.

[0009] Furthermore, the ship's underwater lifting mechanism includes four rectangularly distributed linkage slide blocks slidably connected to two transfer rails, a support plate is fixedly connected between two of the linkage slide blocks close to the same side through a supporting universal joint, a control hydraulic cylinder is fixedly connected to the middle position of the support plate, two symmetrically arranged support slide seats are fixedly connected to the two sides of the support plate surface, and an extrusion lifting plate is fixedly connected between the two support slide seats.

[0010] Through the above technical scheme, the linked slider enables the entire underwater lifting mechanism of the ship to slide on the surface of the transfer rail, the supporting universal joint enables the supporting plate to adapt to the slope of the transfer rail, and the control hydraulic cylinder can realize the two extrusion lifting plates to be close to each other when contracting, and the ship can be lifted up under the interaction of the extrusion force and the conical structure of the bottom of the ship. When the control hydraulic cylinder is extended, the extrusion lifting plate is expanded to both sides, the ship can be lowered, the support plate can lift the ship as a whole, and the extrusion lifting plate can slide at the support slide position.

[0011] Furthermore, the telescopic end of the control hydraulic cylinder is fixedly connected to the extrusion lifting plate at the corresponding position, and a plurality of evenly distributed extrusion grooves are provided on the side where the two extrusion lifting plates are close to each other, and the inner walls of the plurality of extrusion grooves are rotatably connected to extrusion rollers.

[0012] Through the above technical solution, an extrusion roller is arranged at the extrusion groove position, so that the extrusion lifting plate changes sliding friction into rolling friction when extruding the corresponding ship, thereby avoiding damage caused by friction on the bottom of the ship.

[0013] Furthermore, the two linkage sliders near the maintenance lifting mechanism side are fixedly connected with impact blocks near the transfer control mechanism side, a traction connecting ring is fixedly connected between the two linkage sliders near the maintenance lifting mechanism side, and a transfer steel cable is fixedly connected to the middle position of the traction connecting ring.

[0014] Through the above technical solution, when the impact block is impacted or squeezed, the impact block obtains power, causing the ship's underwater lifting mechanism to slide. Under the action of inertia, the ship's underwater lifting mechanism slides into the water, and the traction connecting ring can realize the synchronous movement of the linked sliders on both sides under the action of the transfer cable.

[0015] Furthermore, the transfer control mechanism includes a transfer console, a winding motor is fixedly connected to the surface position of the transfer console, a winding wheel is fixedly connected to the surface position of the transfer console, the driving end of the winding motor is fixedly connected to the rotating shaft of the winding wheel, the winding wheel is fixedly connected to the end of the transfer cable away from the traction connecting ring, and a support seat is fixedly connected to the side of the winding wheel away from the winding motor on the surface of the transfer console, and the rotating shaft of the support seat passes through and is fixedly connected to the wire wheel and the first pulley.

[0016] Through the above technical solution, the winding motor provides power to make the winding wheel reel in, so that the transfer cable can be reeled in, so that the ship's underwater lifting mechanism is pulled, and the position of the winding wheel drives the wire wheel and the first pulley to rotate, so that the control rope is pulled, and when the first pulley rotates, the second pulley rotates under the action of the transmission belt.

[0017] Furthermore, a guide wheel is fixedly connected to the side wall of the transfer console, a support wheel is fixedly connected to the side of the transfer console away from the guide wheel, a support platform is fixedly connected to the lower surface of the transfer console, a torque limiter is provided at the middle position of a rotating shaft that passes through the support platform and is rotatably connected, and a control gear and a second pulley are fixedly connected to both ends of the rotating shaft, and a transmission belt is provided between the second pulley and the first pulley.

[0018] Through the above technical scheme, the guide wheel and the support wheel support and position the control rope, the support platform can support the control gear and the second pulley, and the torque limiter can realize that when the pop-up power plate is fully fixed, the rotating shaft can rotate on one side and not rotate on the other side, that is, the control gear does not rotate but the second pulley can rotate, and the control gear rotates when the winding wheel rotates, so that the pop-up power plate slides to the side of the blocking plate to store energy, and the blocking plate limit positioning plate is used to prevent the pop-up power plate from rebounding.

[0019] Furthermore, a through groove is provided through the upper position of the side wall of the transfer console, the transfer console is fixedly connected to a platform base on the side close to the guide wheel, a sliding groove is provided on the surface of the platform base, a blocking plate is slidably connected to the lower surface of the platform base away from the guide wheel, a return spring is fixedly connected between the blocking plate and the lower surface of the platform base, a pop-up power plate is slidably connected to the surface of the platform base, and the pop-up power plate is slidably connected to the through groove.

[0020] Through the above technical solution, the through groove allows the pop-up power plate and the control rack to slide through, and when the limit positioning plate passes through the blocking plate, it is limited by the blocking plate. When the power needs to be released, the blocking plate is pulled downward so that the blocking plate no longer limits the limit positioning plate. The pop-up power plate then pops out under the action of the power spring and impacts the ship's underwater lifting mechanism, causing the ship's underwater lifting mechanism to slide into the water under the action of inertia.

[0021] A positioning plate is fixedly connected to the middle part of the lower surface of the pop-up power plate away from the through groove, a power spring is fixedly connected between the positioning plate and the sliding groove, the positioning plate is inclined on the side close to the power spring and the blocking plate is inclined on the side away from the power spring, a control rack is fixedly connected to one side of the surface of the pop-up power plate, and the control rack is meshingly connected to the control gear.

[0022] Furthermore, the maintenance lifting mechanism includes an inspection well fixedly connected to the lower surface of the transfer rail, a lifting platform is fixedly connected to the inner wall of the inspection well, two groups of symmetrically arranged lifting rods are slidably connected through the position of the lifting platform, two symmetrically arranged lifting bases are arranged above the lifting platform, and the lifting bases are fixedly connected to the tops of the lifting rods at corresponding positions, and linkage plates are fixedly connected to the bottom positions of the two groups of lifting rods.

[0023] Through the above technical scheme, the inspection well is convenient for setting up the adjusting cam, linkage plate, lifting base, lifting rod and lifting platform underground, and after the ship is lifted, the bottom of the ship can be inspected on the surface of the lifting platform, and when the control rope is pulled, the adjusting cam rotates, and the linkage plate is lifted by the adjusting cam.

[0024] Furthermore, an adjusting cam is rotatably connected to the inner wall of the inspection well, and a control pull rope is fixedly connected to the adjusting cam. The control pull rope passes through the side wall and top of the transfer console, and the control pull rope passes around the support wheel and the guide wheel and is fixedly connected to the wire wheel.

[0025] The beneficial effects of the present invention are as follows: (1) By setting up a maintenance lifting mechanism, the present invention can further lift the ship through the lifting base when the ship is transferred to the maintenance station, so as to facilitate the withdrawal of the ship's underwater lifting mechanism and enable maintenance personnel to perform maintenance at a position below the ship. In this process, the degree of mechanization is high and the efficiency is high, and no additional lifting structure is required to lift the ship; (2) By setting up a ship's underwater lifting mechanism, when the ship travels to a specified position, the lifting plates are squeezed close to each other, and the ship can be lifted under the action of the squeezing roller and clamped between the two squeezed lifting plates. There is no need to manually go into the water to release the rope for fixing, the lifting efficiency is high, and the ship can be directly transferred after the lifting is completed; (3) The maintenance lifting mechanism of the present invention and the ship underwater lifting mechanism share a power source. When the maintenance elevator is moved to the top of the maintenance well, the lifting base rises synchronously, which can realize further lifting of the ship, and in this process, the power plate pops out to store energy. After the ship maintenance is completed, the winding wheel releases the line and squeezes the lifting plate to clamp the ship again, and then pulls down the blocking plate, so that the positioning plate loses the blocking, and the pop-up power plate will impact the impact block, so that the ship underwater lifting mechanism moves and the ship is sent back into the water.

A control hydraulic cylinder 43 is fixedly connected to the middle position of the support plate 47. Two symmetrically arranged support slides 48 are fixedly connected to the positions on both sides of the surface of the support plate 47. An extrusion lifting plate 40 is fixedly connected between the two support slides 48. The linkage sliders 46 enable the ship's underwater lifting mechanism 4 to slide on the surface of the transfer rail 2 as a whole. The support universal joints 49 enable the support plate 47 to adapt to the slope of the transfer rail 2. When the control hydraulic cylinder 43 is contracted, the two extrusion lifting plates 40 can be brought together.

The middle position of the traction connection ring 44 is fixedly connected with the transfer steel cable 3. When the impact block 45 is impacted or squeezed, the impact block 45 obtains power, causing the ship's underwater lifting mechanism 4 to slide, and under the action of inertia, the ship's underwater lifting mechanism 4 slides into the water, and the traction connection ring 44 can realize the synchronous movement of the linkage sliders 46 on both sides under the action of the transfer steel cable 3.

[0040] The lower surface of one end of the two transfer rails 2 located on the shore is fixedly connected to a maintenance lifting mechanism 1 for lifting the ship.

The transfer control mechanism 6 tows the ship to the maintenance station and controls it to lift it up. The side of the transfer rail 2 close to the maintenance lifting mechanism 1 is higher, and the side away from the maintenance lifting mechanism 1 is lower.

[0042] An adjusting cam 15 is rotatably connected to the inner wall of the inspection well 10, and a control pull rope 65 is fixedly connected to the adjusting cam 15. The control pull rope 65 passes through the side wall and top of the transfer console 62, and the control pull rope 65 passes around the support wheel 16 and the guide wheel 64 and is fixedly connected to the wire wheel 611.

[0043] The transfer control mechanism 6 includes a transfer control console 62, a winding motor 5 is fixedly connected to the surface of the transfer control console 62, a winding wheel 61 is fixedly connected to the surface of the transfer control console 62, a driving end of the winding motor 5 is fixedly connected to the rotating shaft of the winding wheel 61, the winding wheel 61 is fixedly connected to the end of the transfer cable 3 away from the traction connection ring 44, and a support seat 60 is fixedly connected to the surface of the transfer control console 62 at the side of the winding wheel 61 away from the winding motor 5, and a wire wheel 611 and a first pulley 610 are fixedly connected to the rotating shaft of the support seat 60, the winding motor 5 provides power to make the winding wheel 61 reel in, so that the transfer cable 3 can be reeled in, so that the ship's underwater lifting mechanism 4 is pulled, and the winding wheel 61 drives the wire wheel 611 and the first pulley 610 to rotate, so that the control pull rope 65 is pulled, and when the first pulley 610 rotates, the second pulley 614 rotates under the action of the transmission belt.

The lower surface of the transfer console 62 is fixedly connected to a support platform 613, and the support platform 613 is provided with a torque limiter 615 at the middle position of the rotating shaft that runs through the rotation connection, and the two ends of the rotating shaft are respectively fixedly connected to a control gear 612 and a second pulley 614, and a transmission belt is provided between the second pulley 614 and the first pulley 610. The guide wheel 64 and the support wheel 16 are connected to the control pulley. The rope 65 is supported and positioned, the support platform 613 can support the control gear 612 and the second pulley 614, and the torque limiter 615 can realize that when the pop-up power plate 69 is fully fixed, the rotating shaft can rotate on one side and not rotate on the other side, that is, the control gear 612 does not rotate while the second pulley 614 can rotate, and when the winding wheel 61 is wound and rotated, the control gear 612 rotates, so that the pop-up power plate 69 slides to the side of the blocking plate 66 to store energy, and the blocking plate 66 limits the positioning plate 617 to prevent the pop-up power plate 69 from rebounding.

[0045] A through slot 63 is provided through the upper position of the side wall of the transfer console 62, and a platform base 68 is fixedly connected to the side of the transfer console 62 close to the guide wheel 64. A sliding slot 619 is provided on the surface of the platform base 68, and a blocking plate 66 is slidably connected to the side of the lower surface of the platform base 68 away from the guide wheel 64. A return spring 67 is fixedly connected between the blocking plate 66 and the lower surface of the platform base 68, and a pop-up power plate 69 is slidably connected to the surface of the platform base 68. The pop-up power plate 69 is slidably connected to the through slot 63, and the through slot 63 allows the pop-up power plate 69 and the control rack 616 to slide through. When the limiting positioning plate 617 passes through the blocking plate 66, it is limited by the blocking plate 66. When it is necessary to release the power, the blocking plate 66 is pulled downward so that the blocking plate 66 no longer limits the limiting positioning plate 617, and the pop-up power plate 69 is popped out under the action of the power spring 618, impacting the ship's underwater lifting mechanism 4, so that the ship's underwater lifting mechanism 4 slides into the water under the action of inertia.

[0047] The working principle of this embodiment is as follows: the ship to be repaired and maintained is moved between two squeezing and lifting plates 40, and two symmetrical control hydraulic cylinders 43 are started, so that the two symmetrical squeezing and lifting plates 40 are brought together, so that the squeezing rollers 42 squeeze the outer wall of the ship, and the ship is lifted during the squeezing process. The outer side of the squeezing and lifting plates 40 is arranged in an arc shape to squeeze the side wall of the ship;

[0048] The winding motor 5 is started, so that the winding wheel 61 rotates to reel in the transfer cable 3, so that the ship's underwater lifting mechanism 4 drives the ship to move as a whole. In this process, the first pulley 610 and the line wheel 611 rotate, which can realize the rotation of the second pulley 614 and the control gear 612. The pop-up power plate 69 is driven to slide by the control gear 612, and the power spring 618 is compressed to realize the energy storage of the power spring 618 and the pop-up power plate 69. At the same time, the second pulley 614 rotates to reel in the control rope 65, and the adjustment cam 15 flips upward, and the adjustment cam 15 squeezes the linkage plate 13 upward, and the linkage plate 13 drives the lifting rod 14 and the lifting base 12 to push upward, so that the ship can be lifted from the ship's underwater lifting mechanism 4;

[0049] By controlling the extension of the hydraulic cylinder 43, the extrusion lifting plate 40 is evacuated from the ship, and the ship can be inspected and maintained. After the inspection and maintenance is completed, the lifting plate 40 is squeezed together again, and the winding wheel 61 is rotated in the opposite direction to relax the transfer cable 3 and the control pull rope 65, so that the ship moves down under the action of gravity and is stably placed on the two ship underwater lifting mechanisms 4, and the blocking plate 66 is pulled downward to make the positioning plate 617 lose its obstruction. Then, the power plate 69 pops up under the action of the power spring 618 to impact the impact block 45, and the maintenance personnel hold the ship underwater lifting mechanism 4 by hand and push it, so as to push the ship underwater lifting mechanism 4 and the ship into the water, and control the extension of the hydraulic cylinder 43, so that the extrusion lifting plate 40 is expanded to both sides, and the ship is completely put into the water to complete the lifting and lowering of the ship.
