Description

Technical Field

[0001] The utility model belongs to the technical field of ship lifting, in particular to a lifting device for repairing small ships. Background Art

[0002] The maintenance of conventional small ships is usually carried out in the dock. Sometimes, if a ship has a serious malfunction and cannot dock, it needs to be shipped to the shore for maintenance. However, if the ship is leaking, it needs to be lifted above the water surface.

[0003] For example, a small ship maintenance and lifting device disclosed in patent application number CN202320026446.6. It includes a gantry, the surface of the gantry is provided with a lifting mechanism, the lifting mechanism includes a slide installed on the surface of the gantry, the surface of the gantry is provided with a motor, the keyway on the output shaft of the motor is connected to a slider, a winch is installed on the lower surface of the motor, a rope is installed on the outer surface of the winch, and a moving wheel is installed at the bottom of the gantry. The utility model provides a small ship maintenance and lifting device, which is designed with a lifting mechanism. When the equipment is in use, the gantry is moved to a suitable position through the moving wheel, and then the winch is adjusted to a suitable position by sliding the motor in the slide, and then the winch is started to lift the ship through the rope. This method is different from the traditional single-arm structure. It is convenient to lift, move, transport and repair the ship during use, and improves the stability of the equipment.

[0004] The existing technology only lifts and repairs ships after they dock. However, in most cases, ships are sailing on the water and encounter sudden accidents. Usually, they cannot return to port for repair and maintenance on their own. In this case, the ship needs to be transported on the water. Sometimes, when a ship leaks or other accidents occur, it is also necessary to lift the ship to the surface of the water, which is impossible with the existing ship maintenance lifting equipment.

[0005] In addition, the overall stability of the existing lifting device is insufficient. During the process of ship consignment, the ship hoisting device may shake due to environmental factors. If the fixation is not stable enough or the lifting device shakes too much, the consigned ship may fall off the lifting device, causing a secondary accident. Utility Model Content

[0006] In order to overcome the deficiencies of the prior art, the utility model provides a hoisting device for the maintenance of small ships. By setting structures such as a universal coupling, a slider, and a spring, the buoyancy tank can still keep the placement plate relatively stable when encountering bumps and vibrations caused by water waves, so that the ship carried on the placement plate can be transported stably. By setting structures such as a suction cup and a telescopic rod, while the support frame supports the bottom of the carried ship, the suction cup can also adsorb and support both sides of the ship, and when the placement plate shakes, the telescopic rod can keep the carried ship stable through its own expansion and contraction.

[0007] In order to achieve the above object, the utility model provides the following technical solution: A hoisting device for the maintenance of small ships, including a placement plate, a plurality of support frames are arranged on the upper end surface of the placement plate, a buoyancy tank is arranged outside the placement plate, a plurality of suction cups are rotatably arranged on both sides of the plurality of support frames, a plurality of universal couplings are arranged on the side wall of the placement plate close to the buoyancy tank, a chute seat is slidably arranged on one side of the buoyancy tank, a slider is slidably arranged inside the chute seat, a spring is arranged between the lower end surface of the slider and the inner bottom surface of the chute seat, a clamping member is arranged on the side surface of the slider, and one end of the clamping member is rotatably connected to the universal coupling. A roller is rotatably arranged on the upper end surface of the buoyancy tank, a rope is connected to the top of the chute seat, and the other end of the rope is fixedly connected to the rotating surface of the roller.

[0008] Optionally, a plurality of first fixing plates are arranged on the end surface of the placement plate, a rotating block is rotatably arranged on the first fixing plate, a plurality of telescopic rods are arranged on the end surface of the rotating block, and the output end of the telescopic rod is rotatably connected to the suction cup.

[0009] Optionally, a positioning block is arranged on the side surface of the buoyancy tank outside the chute seat, a plurality of second clamping holes are arranged on the positioning block, a pin is slidably arranged on the second clamping hole, a plurality of first clamping holes are arranged on the chute seat, and the first clamping hole and the second clamping hole are connected by clamping with the pin.

[0010] Optionally, a pulley is rotatably arranged on the top end surface of the buoyancy tank, and the outer circumferential surface of the pulley abuts against the rope.

[0011] Optionally, a plurality of first through holes are arranged on the end surface of the placement plate, and a plurality of second through holes are arranged on the wall surface of the support frame above the placement plate.

[0012] Optionally, a dragging ring is fixedly arranged on one side of the placement plate.

[0013] Optionally, a water pump is arranged on the buoyancy tank, one end of the water pump is communicated with the inner cavity of the buoyancy tank, and the other end of the water pump extends into an external water source.

[0014] In summary, compared with the prior art, the beneficial effects of this solution are:

[0015] (1) The utility model provides a universal coupling, a slider, a spring and other structures, so that most of the vibrations generated by the buoyancy box after encountering waves can be effectively absorbed and released, thereby keeping the placement board relatively stable, so that the ship consigned on the placement board can be transported stably;

DETAILED DESCRIPTION

[0024] In order to enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0025] Embodiment 1:

[0026] likeFigure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown in Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 , a hoisting device for small ship maintenance has a plurality of support frames 11 provided on the upper end surface of a placement plate 10. A buoyancy tank 16 is provided outside the placement plate 10. A plurality of suction cups 13 are rotatably provided on both sides of the plurality of support frames 11. A plurality of universal couplings 34 are provided on the side wall of the placement plate 10 close to the buoyancy tank. A chute seat 20 is slidably provided on one side of the buoyancy tank 16. A slider 19 is slidably provided inside the chute seat 20. A spring 21 is provided between the lower end surface of the slider 19 and the inner bottom surface of the chute seat 20. A clamping member 18 is provided on the side surface of the slider 19. The clamping member 18 is rotatably connected to one end of the universal coupling 34. A roller 26 is rotatably provided on the upper end surface of the buoyancy tank 16. Two third fixing plates 33 are provided on the upper end surface of the buoyancy tank 16. The roller 26 is rotatably connected to the opposite inner walls of the two third fixing plates 33. A first motor 27 is provided on one side of the third fixing plate 33. The output end of the first motor 27 is fixedly connected to one side of the roller 26. A connecting shaft 31 is provided at the top of the chute seat 20. The connecting shaft 31 is fixedly connected to one end of a rope 25. The other end of the rope 25 is fixedly connected to the rotating surface of the roller 26.

[0027] Specifically, the buoyancy tank 16 is in a hollow state. A plurality of buoyancy tanks 16 provide buoyancy for the entire device to tow a faulty ship.

[0028] The suction cups 13 can adsorb on the hull outer shell of the towed ship. The plurality of suction cups 13 provide stable support for the movement position of the towed ship, so that when the ship is placed on the plurality of support frames 11, it can obtain further multi-point support. And since the hoisting device may shake with different lengths when running on water, the rotatable setting of the plurality of suction cups 13 can effectively prevent the suction cups 13 from falling off due to the shaking of the ship.

[0029] When the hoisting device sails on water, there may be water waves of different degrees. The buoyancy tank 16 will shake with the water. When the buoyancy tank 16 shakes up and down, due to the settings of the clamping member 18, the slider 19 and the spring 21, etc., the placement plate 10 can maintain relative stability.

[0030] The first motor 27 is a waterproof motor, which is a prior art and will not be elaborated in this solution. The output end of the first motor 27 rotates to drive the roller 26 to rotate. The rotation of the roller 26 drives the chute seat 20 to move up and down through the rope 25. The up and down movement of the chute seat 20 drives the placement plate 10 to move up and down.

[0031] The universal coupling 34 is a common universal coupling, which is prior art and will not be elaborated in detail in this solution. The setting of the universal coupling 34 enables the buoyancy tank 16 to be stably connected to one side of the placement plate 10 when the buoyancy tank 16 shakes in multiple directions under the influence of water waves.

[0032] Furthermore, as Figure 4 and Figure 5 shown, a positioning block 36 is arranged on the outer side of the chute seat 20 on the side surface of the buoyancy tank 16. A plurality of second clamping holes 23 are arranged on the positioning block 36. A pin 24 is slidably arranged on the second clamping holes 23. A plurality of first clamping holes 22 are arranged on the chute seat 20. The first clamping holes 22 and the second clamping holes 23 are clamped and connected through the pin 24.

[0033] Specifically, the chute seat 20 slides within the positioning block 36. The pin 24 can clamp and fix the chute seat 20 through the first clamping holes 22 and the second clamping holes 23. When the placement plate 10 does not move up and down, the position of the chute seat 20 is fixed through the pin 24, thereby fixing the placement plate 10.

[0034] Furthermore, as Figure 1 、 Figure 2 and Figure 6 shown, a plurality of first fixing plates 30 are arranged on the end surface of the placement plate 10. A rotating block 12 is rotatably arranged on the first fixing plates 30. A plurality of telescopic rods 35 are arranged on the end surface of the rotating block 12. The output end of the telescopic rod 35 is rotatably connected to the suction cup 13.

[0035] Specifically, the telescopic rod 35 is a corrosion-resistant waterproof elastic telescopic rod, which is prior art and will not be elaborated in detail in this solution. When shipping a ship, the suction cup 13 adsorbs on the outer wall of the ship. When encountering water waves, the placement plate 10 drives by the buoyancy tank 16 and shakes slightly. The shaking of the placement plate 10 will drive the ship to shake. At this time, due to the setting of the telescopic rod 35, the shaking generated by the damaged ship affected by the lifting device can be further absorbed, making the transportation of the damaged ship being towed more stable.

[0036] Furthermore, as Figure 1 shown, a plurality of first through holes 14 are arranged on the end surface of the placement plate 10. A plurality of second through holes 15 are arranged on the wall surface of the support frame 11.

[0037] Specifically, the setting of the first through holes 14 and the second through holes 15 can not only reduce the weight of the device without affecting the overall strength of the lifting device, but also the first through holes 14 can reduce the resistance of water to the bottom surface of the placement plate 10 and play a role in guiding the flow when the placement plate 10 enters the water.

[0038] The provision of the second through-hole 15 can reduce the resistance of water to the side wall of the support frame 11 when the placement plate 10 moves horizontally underwater to the bottom of the faulty ship, and also has the function of water diversion.

[0039] Furthermore, as Figure 2 shown, two second fixing plates 32 are provided on the upper end surface of the buoyancy tank 16, and a pulley 28 is rotatably provided between the two second fixing plates 32. The outer circumferential surface of the pulley 28 abuts against the rope 25.

[0040] Specifically, the provision of the pulley 28 plays a transmission role when the roller 26 winds and unwinds the rope 25, and can also prevent the rope 25 from contacting the outer wall of the buoyancy tank 16.

[0041] Furthermore, as Figure 2 shown, a dragging ring 29 is fixedly provided on one side of the placement plate 10.

[0042] Specifically, the provision of the dragging ring 29 facilitates the traction of the hoisting device by the power boat.

[0043] Furthermore, as Figure 1 shown, a water pump 17 is provided on the buoyancy tank 16. One end of the water pump 17 communicates with the inner cavity of the buoyancy tank 16, and the other end of the water pump 17 extends into the external water source.

[0044] Specifically, the water pump 17 is a common water pump, which is a prior art and will not be elaborated in this solution. The provision of the water pump 17 can pump the water inside the cavity of the buoyancy tank 16 and discharge it into the water, causing the buoyancy tank 16 to float, and can also pump water into the cavity of the buoyancy tank 16 to cause the buoyancy tank 16 to sink.

[0045] First, when a ship breaks down, the towing boat drives the hoisting device to move in front of the faulty ship, removes a plurality of pins 24, and then starts the first motor 27. The output end of the first motor 27 drives the roller 26 to rotate. The rotation of the roller 26 causes the chute seat 20 to move downward along the inner wall of the positioning block 36. The downward movement of the chute seat 20 drives the slider 19, the clamping member 18, and the universal coupling 34 to move downward, thereby driving the placement plate 10 to move downward. The downward movement of the placement plate 10 drives other components provided on the placement plate 10 to move downward until the placement plate 10 moves to the horizontal position at the bottom of the faulty ship. Then, the towing boat drives the hoisting device to move towards the faulty ship until the placement plate 10 moves to the bottom of the faulty ship.

[0046] Next, start the first motor 27. The rotation of the first motor 27 drives the rotation of the winding roller 26. The rotation of the winding roller 26 drives the upward movement of the chute seat 20 through the rope 25. The upward movement of the chute seat 20 drives the upward movement of the placement plate 10. The upward movement of the placement plate 10 drives the upward movement of the faulty vessel until the faulty vessel and the placement plate 10 are out of the water. Then, adjust the position of the chute seat 20 so that the first clamping hole 22 and the second clamping hole 23 correspond, and insert the bolt 24 to fix the chute seat 20, thereby fixing the placement plate 10. During the process of lifting the faulty vessel, start the water pump 17 to control the water injection volume in the cavity of the buoyancy tank 16 so that the buoyancy of the buoyancy tank 16 is appropriate.

[0047] Finally, rotate the telescopic rod 35. The rotation of the telescopic rod 35 drives the rotation of the suction cup 13. Then, adsorb the suction cup 13 on the outer wall of the faulty vessel to further fix the vessel.
