Description

Technical Field

[0001] The invention relates to the technical field of fender hangers, in particular to a multi-buffered fender hanger. Background Art

[0002] When a ship is docked at a port, the side of the ship will come into contact with the concrete of the shore and collide with it, causing deformation of the side of the ship, resulting in damage to the ship and even affecting the normal operation of the ship. In order to protect the side of the ship, fenders are generally installed outside the concrete of the shore. When the side of the ship collides with the fender, the fender is made of shock-absorbing material, thus avoiding damage to the side of the ship;

[0003] The existing fender hangers still have the following technical problems when in use, such as:

[0004] 1. The existing fender hanger is fixed outside the concrete of the shore, which makes its position fixed, but the water level is not constant. If the water level is too high or too low, it will not protect the ship's side, which makes the existing fender hanger subject to greater limitations in use;

[0005] 2. The existing fender hanger has an unsatisfactory buffering effect. The main reason is that the existing fender hanger only uses elastic materials for single-layer protection. This type of buffering is prone to the problem that if the ship has a large mass, its inertia must be large, which will make the elastic material of the single-layer protection unable to fully withstand the inertia of the ship, so that the ship's side will still be impacted by the rigid force, causing damage to the ship;

[0006] Therefore, a multi-buffer fender hanger is needed to solve the above problems. Summary of the invention

[0007] The object of the present invention is to provide a fender hanger with multiple buffers to solve the problems in the above background technology that the existing fender hanger cannot adjust the height according to the water level and the buffering effect is not ideal.

[0008] To achieve the above object, the present invention provides the following technical solutions:

[0009] A multi-buffer fender hanger comprises a main support platform, an anti-corrosion cover, a roller groove, a roller component, a self-adjusting fender mechanism, a primary buffer mechanism, and a secondary buffer mechanism. Both sides of the main support platform are slidably connected with secondary support platforms, and the main support platform is provided with a self-adjusting fender mechanism, a fender plate is connected to the self-adjusting fender mechanism, and a primary buffer mechanism is provided on the rear side of the fender plate, a secondary buffer mechanism is provided inside the secondary support platform, and the primary buffer mechanism and the secondary buffer mechanism are both connected to the self-adjusting fender mechanism, and the primary buffer mechanism and the secondary buffer mechanism are also connected.

[0010] Furthermore, the self-adjusting fender mechanism includes a balloon, a rope winding assembly, a worm gear structure, a wire rope, a suspension guide wheel, a transmission rod, a toggle tube and a driving block, the lower end bearing of the transmission rod is connected to the inner bottom end of the main support platform, and the upper end bearing of the transmission rod passes through to the top of the main support platform, the middle part of the transmission rod is threadedly connected to the driving block, and both sides of the driving block are axially connected to one end of the toggle tube, the other end of the toggle tube is connected to the balloon through a chain rope, the upper surface of the main support platform is provided with a rope winding assembly, and the rope winding assembly includes a support plate body and a rope winding shaft, four support plates are connected in series through the rope winding shaft, and the rope winding shaft is connected to the support plate body bearing, the rope winding shaft between two adjacent support plates in the middle is connected to the upper end of the transmission rod through the worm gear structure, and one end of the wire rope is wound between two adjacent support plates at both ends, the other end of the wire rope is connected to the fender by bypassing the suspension guide wheel, and the suspension guide wheel is tilted and fixed to the upper surface of the main support platform.

[0011] By adopting the above technical scheme, the height of the driving block can be adjusted according to the water level through the balloon. When the height of the driving block changes, it will drive the transmission rod to rotate, and then use the worm gear structure to drive the rope winding shaft to rotate, so as to achieve the purpose of winding or releasing the wire rope, thereby automatically adjusting the height of the fender according to the water level.

[0012] Furthermore, the driving block is provided with a hole for the transmission rod to pass through, and the outer side of the middle and lower part of the transmission rod and the hole of the driving block are provided with mutually matching twist threads.

[0013] By adopting the above technical solution, a relatively small buoyancy generated by the floating balloon can be achieved, which drives the driving block to move smoothly on the transmission rod, thereby realizing the rotation of the transmission rod.

[0014] Furthermore, the primary buffer mechanism includes a support plate, a square tube, an air guide hose, an air suction pipe, an air extraction assembly, an L-shaped support plate, a sliding plate, an exhaust hole and a pull-out piston member, the sliding plate is slidably connected to a groove set in the front side of the auxiliary support platform, and the front surface axis of the sliding plate is connected to one end of the support plate, the other end of the support plate is axially connected to a slider, and the slider is slidably connected to the rear side of the fender, the inward side axis of the support plate is connected to one end of the pull-out piston member, and the other ends of the two pull-out piston members are respectively sealed and slidably connected to the inside of the two ends of the square tube, and the middle part of the pull-out piston member is sealed and connected to the end of the square tube through an elastic membrane. The membrane is made of corrosion-resistant rubber material, and the square tube is connected with air hoses near both ends, and the two air hoses are respectively connected to the toggle tubes on both sides of the driving block. Two L-shaped support plates are arranged on the driving block, and a vacuum assembly is arranged between the lower surface of each L-shaped support plate and the toggle tube. The vacuum assembly includes a piston tube and a piston rod. The piston tube is fixedly connected to the corresponding lower surface of the L-shaped support plate, the upper end of the piston rod is sealingly and slidably connected to the inner side of the lower end of the piston tube, and the lower end shaft of the piston rod is connected to the toggle tube. The upper part of the piston tube is connected with the toggle tube through an air intake pipe, and an exhaust hole is also arranged on the upper part of the piston tube.

[0015] By adopting the above technical solution, when the side of the ship hits the fender, the impact force causes the fender to move closer to the main support platform, and the two pull-out piston members approach each other. Due to the action of water waves, the toggle tube will swing up and down, so that the piston rod on the air extraction assembly can move back and forth in the piston tube, thereby extracting the gas in the toggle tube. When the pull-out piston member blocks the air hole on the square tube and connects it with the air guide hose, the gas between the end of the square tube and the pull-out piston member can be continuously extracted through the air guide hose, so that the two pull-out piston members gradually move away from each other, thereby resisting the force of the pull-out piston members approaching each other due to the movement of the fender toward the main support platform, and achieving a preliminary buffering effect.

[0016] Furthermore, the secondary buffer mechanism includes a ventilation pipe, an air guide component and an air collecting tank. The air guide component is also composed of a piston tube and a piston rod. One end of the piston tube thereon is fixedly connected to the side surface of the auxiliary support platform, and one end of the piston rod on the air guide component is sealingly and slidably connected to the inner side of the other end of the corresponding piston tube, and the other end of the piston rod is fixedly connected to the side surface of the sliding plate. The air guide components are evenly distributed between the side surfaces of the auxiliary support platform and the side surfaces of the sliding plate. The piston tubes on the air guide components are all through-connected to the air collecting tank, and the air collecting tank is through-connected to the balloon via the ventilation pipe.

[0017] By adopting the above technical solution, in the process of the two pulling and pulling piston parts approaching each other, the sliding plate connected to them will also slide in the groove set on the front side of the auxiliary support platform. At this time, the piston rod on the gas guide assembly will move toward the piston tube on it, so that the gas in the piston tube is transported to the gas collecting tank and then to the balloon through the ventilation pipe, so that the balloon will expand. The expanded balloon can not only increase the buoyancy to ensure that it can stably drive the drive block to move, but also can squeeze the gas inside it through the elastic force of the balloon, so that the gas has a tendency to flow toward the gas guide assembly, and can further cushion the ship's side.

[0018] Furthermore, the sliding connection structure between the auxiliary support platform and the main support platform and the sliding connection structure between the slider at the other end of the support plate and the rear side of the fender are both composed of roller grooves and roller components, and the roller grooves are arranged on the side of the auxiliary support platform and the rear side of the fender, and the roller components are arranged on the side of the main support platform and the slider at the other end of the support plate, the roller components are rollingly connected to the roller grooves, and the rear side of the sliding plate connected to the axis at one end of the support plate is also rollingly connected to the inner surface of the groove on the front side of the auxiliary support platform through the roller component.

[0019] By adopting the above technical solution, the sliding structure composed of the roller groove and the roller component can facilitate smooth sliding between the components.

[0020] Furthermore, the arcuate surface of the main support platform, the front side surface of the auxiliary support platform and the rear side surface of the fender are all provided with anti-corrosion covers, and the structure of the anti-corrosion covers is a spring rubber structure, which is convenient for the movement of the toggle tube and the support plate. The anti-corrosion cover of the arcuate surface of the main support platform is sealed and penetrated by two toggle tubes, and the anti-corrosion covers on the front side surface of the auxiliary support platform and the rear side surface of the fender are respectively sealed and penetrated by both ends of the support plate.

[0021] By adopting the above technical solution, the anti-corrosion cover can prevent the water from corroding the components on the fender hanger, so as to prevent the components from failing to operate normally due to corrosion.

[0022] Furthermore, an air hole communicating with the interior of the square tube is provided at the upper middle end of the square tube, and the air guide hose is communicated with the air hole through the square tube in a natural state.

[0023] By adopting the above technical solution, the air guide hose can absorb external air through the air holes on the square tube in a natural state, thereby replenishing the gas extracted in the dial tube.

[0024] Furthermore, the suction pipe is provided with a one-way valve to facilitate the suction pipe to extract the gas into the switching tube in one direction. The upper end of the main support platform is provided with a hollow hole that penetrates the interior thereof, so that the gas extracted from the suction pipe can be discharged to the outside from the hollow hole through the exhaust hole.

[0025] By adopting the above technical solution, it is possible to easily balance the air pressure inside the main support platform through the hollow holes, thereby preventing the air pressure inside the main support platform from being too high and causing the main support platform to be cracked.

[0026] Furthermore, an irregular interval matching the outer diameter of the balloon is formed between the main support platform and the auxiliary support platform, so as to facilitate the ascent or descent of the balloon within the specified interval.

[0027] The above technical solution is adopted to prevent the balloon from floating to other positions, causing the toggle tube to rotate too much, so that even if the balloon automatically adjusts its height according to the water level, the toggle tube cannot drive the drive block to move.

[0028] Compared with the prior art, the invention has the following beneficial effects: the multi-buffered fender hanger can not only adjust the height adaptively according to the change of water level, so that when the ship is docked at the port, the ship's side can stably contact the fender hanger, thereby buffering the inertia of the hull, so as to provide stable protection for the ship, but also can make the fender hanger have better buffering performance through the impact of waves and ships on the fender hanger, thereby improving its buffering effect:

[0029] 1. The airbag can drive the driving block to move in the vertical direction when the water level changes, so as to drive the transmission rod to rotate. Then, the worm gear structure is used to drive the rope winding assembly to wind or release the wire rope, so as to move the fender up or down, so that the fender hanger can adjust the position of the fender adaptively according to the water level change, so that no matter how the water level changes, the ship's side can contact the fender, thereby preventing the ship from being damaged;

[0030] 2. The water waves can make the toggle tube swing back and forth, so that the air extraction assembly can continuously extract the gas at both ends of the square tube through the suction tube, the toggle tube and the air guide hose. Since the air hole in the middle of the square tube is connected with the air guide hose in a natural state, the gas at both ends of the square tube can be supplemented by external gas. When the fender is impacted, the pull-out piston component moves, which hinders the connection between the air hole and the air guide hose. At this time, the pull-out piston components can be moved away from each other through the action of the air extraction assembly, thereby resisting the force of the fender being impacted and moving, thereby preliminarily buffering the ship's side;

[0031] 3. When the piston member is pulled out and moved, the support plate will also drive the sliding plate to move, so that the gas in the gas guide assembly is squeezed into the gas collecting tank, and then enters the balloon through the ventilation pipe, so that the balloon expands. The buoyancy of the expanded balloon cannot be improved, and because the balloon is elastic, it will squeeze the gas inside it, so that the gas guide assembly has a tendency to push the sliding plate to move in the opposite direction, thereby further cushioning the ship's side.

[0046] Embodiment 1:

[0047] In order to solve the problem that the fender hanger cannot adaptively adjust the fender position according to the water level in the past, thus making the use of the fender hanger subject to great limitations, the following technical solutions are provided, specifically,

When in use, the height of the balloon 5 will rise or fall as the water level rises or falls. The change in the position of the balloon 5 can drive the driving block 22 to move up or down, and the twisted thread connection between the driving block 22 and the transmission rod 12 can make the transmission rod 12 rotate, so that the worm gear structure 9 can drive the rope winding assembly 8, so that the wire rope 10 can lift or lower the fender 3, so that the position of the fender 3 can be adaptively adjusted with the height of the water level. At this time, no matter what the height of the water level is, the side of the ship can contact the fender 3, thereby preventing the side of the ship from directly contacting the concrete and being damaged.

[0049] Embodiment 2:
