Description

Technical Field

[0001] The invention relates to the technical field of floating mooring posts, in particular to a telescopic and adjustable floating mooring post device. Background Art

[0002] The floating bollard rises and falls with the change of the filling and draining water level of the lock chamber by its own buoyancy. The bollard is not only responsible for the horizontal positioning of the ship entering the lock, but also for ensuring that the relative position of the ship remains unchanged within the horizontal range, and allowing the ship to gradually and safely transition from one horizontal plane to another in an orderly manner as the water in the lock chamber is filled and drained;

[0003] The main moving parts of the buoy are rollers, which are composed of longitudinal wheels and transverse wheels. They rotate in a circle by the relative sliding of the sleeve and the shaft. Since the working environment and lubrication conditions of the rollers are very poor (especially the underwater part), although there are grease nozzles to add grease regularly, it is inconvenient to repair the lock during operation, and it is impossible to add grease regularly. At the same time, the coating of the channel steel track where the buoy is located has been maintained for too long and has fallen off, which can easily cause some aquatic organisms to attach to the surface of the channel, causing the channel to become thicker and narrower, which can easily cause the buoy to be blocked. Figure 1 As shown in the figure, when the buoys are blocked in the slideways on both sides of the lock chamber, the ship moves up and down during the filling and discharge of water in the lock chamber. If the ship rope is not separated from the buoys in time, it is easy to cause the hull to capsize;

[0004] To this end, we propose a telescopic and adjustable floating mooring post device. Summary of the invention

[0005] The object of the present invention is to provide a telescopic and adjustable floating mooring post device to solve the problem in the above background technology that the buoy is blocked in the track, causing the tethered ship to capsize or sink, and the buoy cannot perform self-cleaning protection.

[0006] To achieve the above object, the present invention provides the following technical solutions:

A fixed frame is fixed to the float and is located on one side of the fixed cover by spot welding, and a first gear is symmetrically and movably connected to the one side of the top of the fixed frame by a bearing. A toothed chain is sleeved on the three first gears, and a sealing cylinder is installed on the toothed chain. One side of the sealing cylinder is fixed to one side of the fixed frame by bolts. A piston plate is slidably connected to the sealing cylinder, and the two ends of the toothed chain are correspondingly connected to the two sides of the piston plate. A rotating rod is symmetrically fixed to one side of the two first gears by spot welding, and one end of the rotating rod passes through the float and is movably connected to a contact sleeve. One end of the connecting pipe passes through one side of the fixed frame and is connected to the sealing cylinder.

[0009] Furthermore, a column tube is fixed to the bottom inner wall of the movable cover by bolts, and a reset hole is opened at the bottom of the column tube and the movable cover, a buffer pad is adhered inside the column tube and at the top of the reset hole, a bolt column is slidably connected inside the column tube, and one end of the bolt column passes through the column tube and is slidably connected to the column tube.

[0010] Furthermore, sliding grooves are symmetrically provided on both sides of the top of the movable cover, and a resist column is slidably connected in the sliding groove, a pressure plate is fixed to the top of the resist column by spot welding, one end of the bolt column passes through the pressure plate and is slidably connected to the pressure plate, a spring is provided on the outer wall of the resist column and on the opposite side of the pressure plate and the movable cover, and an anti-locking sleeve is provided on the top of the pressure plate and on the outer wall of the bolt column.

[0011] Furthermore, the inner wall of one side of the movable cover is symmetrically rotatably connected to the limiting plate, and a slide groove is passed through one side of the limiting plate, and the other side of the limiting plate passes through the column tube and abuts against the bottom of the bolt column, and the inner wall of one side of the movable cover is symmetrically fixed with the limiting block by spot welding, and the bottom of the limiting block abuts against one side of the limiting plate.

[0012] Furthermore, the two sides of the buoy are symmetrically and movably connected with the first limiting wheel through bearings, the top of the buoy is symmetrically and movably connected with the second limiting wheel through bearings, the bottom of the buoy is fixed with a bracket by bolts, and the second limiting wheel is symmetrically and movably connected with the bracket through bearings.

[0013] Furthermore, the second limiting wheel is located on one side of the bracket and is sleeved and fixed with a second gear, one side of the bracket is movably connected with a rotating drum, and a third gear is sleeved and fixed on the outer wall of the rotating drum, the second gear is meshingly connected with the third gear, an annular brush is fixed to one side of the rotating drum by bolts, one side of the bracket is located in the rotating drum and is rotatably connected with a brush rod, and protrusions are symmetrically fixed on both sides of the brush rod by spot welding.

[0014] The adjustment method of the telescopically adjustable floating mooring post device is as follows:

[0015] The pull-down operation is based on the downward pulling force of the bolt column as the hull descends with the water surface, so that the rope body presses the pressure plate downward. At this time, the pressure plate drives the anti-column to move downward in the slide slot and contacts the limit plate in the slide slot. The anti-column presses the limit plate downward, and the entire limit plate tilts up and lifts the bolt column in the column tube. After the bolt column rises 6-7cm in height, it begins to drop as a whole without the contact of the limit plate, causing the entire bolt column to fall onto the buffer pad at the bottom of the column tube. At this time, the rope loop tied to the bolt column is separated from the entire buoy because it is no longer supported by the bolt column.

[0016] During the pull-up operation, the liquid level rises and drives the boat up. At this time, the buoy is stuck in the groove, so that the boat is pulled obliquely above the bolt. At this time, the buoy begins to enter the bottom of the water surface, and the floating plate at the bottom of the buoy also begins to enter the water. The buoyancy of the floating plate as a whole increases, and begins to push the piston column upward, so that the piston column pushes the hydraulic oil in the reservoir into the connecting pipe. The hydraulic oil enters the sealing cylinder along the connecting pipe, pushing the single-sided piston plate in the sealing cylinder to the other side, thereby driving the entire toothed chain to rotate. The rotation of the toothed chain drives the first gear to rotate, so that the rotating rod rotates and disengages from the abutment on one side of the movable cover. At this time, the movable cover has no abutment on one side of the movable cover and begins to rotate in the fixed cover, so that the entire bolt is facing the pulling angle of the rope loop, so that the rope loop is separated from the buoy under the action of the hull pulling force.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. In the present invention, by specifically analyzing the specific clamping position of the buoy in the channel and the tension applied by the hull rope on the bolt, when the hull rope pulls down the bolt, the pressure plate on the bolt is driven to move downward at the same time, and the abutment column connected by the pressure plate drives the limit plate to rotate, thereby breaking away from the fixation of the entire bottom of the bolt, so that the entire bolt is retracted into the column tube, and the rope loop at the top of the bolt successfully breaks away from the buoy after the bolt is no longer fixed. When the hull rope pulls up the bolt, the buoyancy of the bottom floating plate as a whole sinks into the water body due to the blockage of the buoy is increased, and the hydraulic oil in the liquid storage tank is pushed into the sealing cylinder, and the entire piston plate is pushed to move and the gear chain is driven to rotate, thereby realizing the rotation of the rotating rod, and the rotating rod rotates and breaks away from the abutment against the movable cover, so that the bolt on the movable cover can be rotated, which is conducive to the tension generated by the hull to pull the rope loop out from the top of the bolt, and the bolt is quickly released by the rope when the buoy is blocked in the channel, so as to avoid the problem of the overall capsizing of the hull and ensure the safe movement of the hull in the lock chamber.

[0019] 2. In the present invention, the second limiting wheel moves in the groove to drive the rotating drum to rotate, so that the annular brush installed at the end of the rotating drum rotates and rotationally brushes the longitudinal wheel track. While the rotating drum rotates, the inner wall continuously abuts against the brush rod with a protrusion, so that the brush rod starts to move up and down and brushes the horizontal wheel motion track in the groove. The up and down movement of the float can also brush the channel steel track in the groove, thereby avoiding the problem of aquatic organisms attaching to the channel steel track due to long-term immersion in water, which blocks the normal movement of the float.

DETAILED DESCRIPTION

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] See also Figure 1-8 , the present invention provides a technical solution:

[0031] Embodiment 1:

[0032] like Figure 1 As shown in the figure, there are two hazards when the floating column (floating mooring column) located in the guide rail of the gate wall floating column (floating mooring column) is blocked and stuck. The floating column is stuck at the bottom of the gate. As the water level rises, the ship may be sunk; the floating column is stuck on the gate surface. As the water level drops, the ship may be overturned. At the same time, there is a risk that the mooring rope will break and rebound and injure the crew. Therefore, the present invention promptly detaches the mooring rope from the buoy 1 when the floating column is blocked to avoid the problem of the overall capsizing of the ship. In specific operation, the entire buoy 1 is as follows Figure 2 As shown, the first limiting wheel 2 and the second limiting wheel 3, that is, the transverse wheel and the longitudinal wheel, are arranged on the upper and lower sides of the buoy 1. In daily work, especially the transverse wheel and the longitudinal wheel at the bottom of the buoy 1, grease needs to be added regularly to prevent water from corroding the shaft and the sleeve of the transverse wheel and the longitudinal wheel. The bolt column 8 installed on the top of the buoy 1 has a relatively smooth surface and has no limiting bend on the top. Therefore, when the buoy 1 is working normally, the bolt column 8 installed on the top is required to maintain an angle of about 15 degrees with the ship deck, so that when the tethering operation is performed, the rope loop generates a downward pulling force to avoid the problem of falling off the column;

[0033] However, when the entire buoy 1 is blocked above the liquid surface, the hull descends with the water surface, while the buoy 1 does not move, causing the hull to slowly move toward the buoy 1. When the entire rope is straightened, the hull will capsize. Therefore, when the entire rope is tightened, it is necessary to explain the rope slippage, such as Figure 3 As shown, the entire rope is tied to the top third of the bolt column 8 and is located on the top of the pressure plate 7. When the rope is tightened, the angle between the bolt column 8 and the hull deck is greater than 45 degrees. At this time, the rope begins to pull down the pressure plate 7 on the surface of the bolt column 8, causing the entire pressure plate 7 to drive the stop column 11 to press down the spring 12. At this time, the stop column 11 begins to contact the limit plate 13 in the slide groove 10, and one side of the limit plate 13 drops, and the other side will tilt up. At this time, the tilted end of the limit plate 13 lifts the bolt column 8. When the entire bolt column 8 rises 6-7cm, the limit plate 13 is separated from the contact with the bottom of the bolt column 8. The bolt column 8 successfully falls onto the buffer pad 16 on the inner wall of the bottom of the column tube 6 by its own gravity. At this time, the rope slides off the buoy 1 without the fixation of the bolt column 8, and the entire spring 12 lifts the pressure plate 7 to its original position.

[0034] When the rope presses down the pressure plate 7 and the pressure plate 7 does not contact the limit plate 13, the limit block 14 on the inner wall of the movable cover 5 abuts against one side of the limit plate 13 to support the bolt column 8. When the entire bolt column 8 needs to be reset, a reset hole 15 is opened at the bottom of the movable cover 5 and the column tube 6. The operator uses a column rod to insert the reset hole 15 to push up the bolt column 8 until the limit plates 13 on both sides of the bolt column 8 can rotate. The weight of the entire limit plate 13 on the column tube 6 side is greater than that on the slide groove 10 side, so that the entire limit plate 13 can rotate automatically. An anti-locking sleeve 9 is installed on the top of the entire pressure plate 7 and around the bolt column 8 to prevent the rope from being too close to the column tube 6 when the rope is pressed down, resulting in the bolt column 8 being unable to descend or the descent speed being slowed down, thereby affecting the rope release and rope release rate of the entire buoy 1;

[0035] When the entire buoy 1 is blocked at the bottom of the liquid, the ship pulls up the rope due to the rising water level, which also causes the hull to move closer to the buoy 1. Since there is no limit structure at the end of the entire bolt 8, when the buoy 1 is blocked underwater, the wet telescopic rope will most likely slide directly from the bolt 8 and directly detach from the buoy 1. Due to the existence of the angle, the rope will still be unable to detach from the bolt 8. For this reason, a floating plate 20 is installed at the bottom of the entire buoy 1. When the buoy 1 moves up and down normally with the ship, the liquid level cannot completely cover the floating plate 20. When the entire buoy 1 is blocked in the track, the entire floating plate 20 will be immersed in the water as the liquid level rises. According to Archimedes' principle, buoyancy is related to liquid density and the volume of liquid displaced by the object. Therefore, the deeper the object is immersed before being completely immersed in the water, the greater the volume of liquid displaced by the object, the greater the buoyancy, and the greater the force applied. At this time, the floating plate 20 drives the piston rod 19 to squeeze the hydraulic oil in the liquid storage tank 17 upward, causing the hydraulic oil to enter the sealing cylinder 216 in the rotating adjustment mechanism 21 along the connecting pipe 18, as shown in FIG. Figure 5 and Figure 6 As shown, a piston plate 217 is slidably connected in the sealing cylinder 216, and the connecting pipe 18 is connected to one side of the sealing cylinder 216, so that the hydraulic oil can reach one side of the piston plate 217 in the sealing cylinder 216, pushing the piston plate 217 to move to the other side. The two sides of the piston plate 217 are connected with a toothed chain 215, so that the toothed chain 215 starts to rotate on the first gear 212. The entire first gear 212 is divided into three and fixed on a fixing frame 211, and the fixing frame 211 is located in the buoy 1. Two of the first gears 212 are fixed with rotating rods 213. When the first gear 212 rotates, it will drive the rotating rod 213 to rotate. Figure 7As shown, under normal operation of the buoy 1, the abutment sleeve 214 at the end of the rotating rod 213 abuts against one side of the movable cover 5 in the fixed cover 4, so that the entire movable cover 5 cannot rotate. When the entire rotating rod 213 drives the abutment sleeve 214 to rotate, the abutment sleeve 214 is separated from the abutment and fixation on one side of the movable cover 5. At this time, when the rope pulls the bolt 8 set on the movable cover, it will drive the movable cover to rotate as a whole. The rotation of the bolt 8 makes the pulling direction of the rope gradually coincide with that of the rope. Therefore, when the ship pulls the rope, the rope will be quickly pulled off the buoy 1. When the buoy 1 is blocked in the channel, the bolt 8 is used to quickly release the rope, so as to avoid the problem of the overall capsizing of the hull and ensure the safe movement of the hull in the lock chamber.

[0036] Embodiment 2:

[0037] like Figure 4 As shown, in order to reduce the probability of the buoy 1 being blocked in the track, a bracket 22 is symmetrically fixed at the bottom of the buoy 1, and the entire bracket 22 is movably connected with the second limiting wheel 3 and the rotating drum 24, and an annular brush 26 is arranged at one end of the rotating drum 24. When the entire second limiting wheel 3 moves in the track, the second limiting wheel 3 rotates and drives the rotating drum 24 to rotate through the meshing connection of the second gear 23 and the third gear 25, and the rotation of the rotating drum 24 drives the annular brush 26 to rotate, and the annular brush 26 begins to unfold under the action of centrifugal force and brushes the surface of the horizontal wheel track to remove the water plants attached to the track surface;

[0038] At the same time Figure 8 As shown, the inner wall of the entire rotating drum 24 is evenly provided with convex surfaces, and the brush rod 27 rotatably connected to the bracket 22 penetrates the rotating drum 24 and abuts the track surface of the longitudinal wheel at one end. At the same time, protrusions 28 are provided on both sides of the brush rod 27, and one side of the protrusion 28 abuts the convex surface of the inner wall of the rotating drum 24. When the entire rotating drum 24 rotates, the alternation of the convex surfaces continuously drives the brush rod 27 to move up and down, so that the brush head at the end of the brush rod 27 can brush the track surface of the longitudinal wheel. The second limiting wheel 3 at the bottom of the buoy 1 can also brush the channel steel track in the groove while moving up and down, so as to avoid the problem of aquatic organisms attaching to the channel steel track due to long-term immersion in water, thereby blocking the normal movement of the buoy 1, thereby reducing the probability of the buoy 1 being blocked in the track.

[0039] The emergency unroping design of the entire buoy 1 and the automatic washing of the inner wall of the track only serve to protect the normal activities of the ship and reduce the probability of blockage of the buoy 1. Regular maintenance and oiling of the buoy 1, rust removal of the track and application of anti-rust paint are the operations to maintain the normal operation of the buoy 1 and maximize the benefits.

[0040] The working principle of the buoy rope release of the present invention:

[0041] As the hull descends with the water surface, the rope body presses the pressure plate 7 downward based on the downward pulling force of the bolt column 8. At this time, the pressure plate 7 drives the stop column 11 to move downward in the slide groove 10 and contacts the limit plate 13 in the slide groove 10. The stop column 11 presses the limit plate 13 downward, and the entire limit plate 13 tilts up and lifts the bolt column 8 in the column tube 6. After the bolt column 8 rises to a height of 6-7 cm, it begins to descend as a whole without the contact of the limit plate 13, so that the entire bolt column 8 falls onto the buffer pad 16 at the bottom of the column tube 6. At this time, the rope loop tied to the bolt column 8 is separated from the entire buoy 1 because there is no support from the bolt column 8.

[0042] The rising liquid level drives the hull up. At this time, the buoy 1 is stuck in the groove, so that the hull is based on the pulling force of the bolt column 8 obliquely above. Since the buoy 1 begins to enter the bottom of the water surface at this time, the floating plate 20 at the bottom of the buoy 1 also begins to enter the water body. The buoyancy of the floating plate 20 as a whole increases, and the piston column 19 begins to push up, so that the piston column 19 pushes the hydraulic oil in the liquid storage tank 17 into the connecting pipe 18. The hydraulic oil enters the sealing cylinder 216 along the connecting pipe 18, pushing the single-side piston plate 217 in the sealing cylinder 216 to move to the other side, thereby driving the entire toothed chain 215 to rotate. The rotation of the toothed chain 215 drives the first gear 212 to rotate, so that the rotating rod 213 rotates and disengages from the abutment on one side of the movable cover 5. At this time, there is no abutment of the movable cover 5 on one side of the movable cover 5 and it begins to rotate in the fixed cover 4, so that the entire bolt column 8 faces the rope loop tension angle, so that the rope loop is separated from the buoy 1 under the action of the hull tension.

After the bolt column (8) rises to a height of 6-7 cm, it begins to descend as a whole without the contact of the limit plate (13), so that the entire bolt column (8) falls onto the buffer pad (16) at the bottom of the column tube (6). At this time, the rope loop tied to the bolt column (8) is separated from the entire buoy (1) because it is no longer supported by the bolt column (8); The upper pull-off rope is operated, and the liquid level rises, driving the hull up. At this time, the buoy (1) is clamped in the channel, so that the hull is pulled obliquely upward by the bolt column (8). Since the buoy (1) begins to enter the bottom of the water surface at this time, the floating plate (20) at the bottom of the buoy (1) also begins to enter the water body. The buoyancy of the floating plate (20) as a whole increases, and the piston column (19) begins to be pushed upward, so that the piston column (19) pushes the hydraulic oil in the liquid storage tank (17) into the connecting pipe (18), and the hydraulic oil enters the sealing cylinder (2) along the connecting pipe (18). 16), pushes the single-side piston plate (217) in the sealing cylinder (216) to move to the other side, thereby driving the entire toothed chain (215) to rotate. The rotation of the toothed chain (215) drives the first gear (212) to rotate, so that the rotating rod (213) rotates and disengages from the abutment on one side of the movable cover (5). At this time, the movable cover (5) starts to rotate in the fixed cover (4) without the abutment of the movable cover (5), so that the entire bolt column (8) is facing the rope loop tension angle, so that the rope loop is separated from the buoy (1) under the action of the hull tension.
