A telescopic and adjustable floating mooring post device

Abstract

The present invention discloses a floating mooring post device with telescopic adjustment, which relates to the technical field of floating mooring posts and is used to solve the problem that the buoy is blocked in the track and causes the moored ship to capsize or sink. The device comprises a buoy; the present invention specifically analyzes the specific clamping position of the buoy in the channel and the tension applied by the hull rope on the bolt post. When the hull rope pulls down the bolt post, the abutment post connected by the pressure plate drives the limit plate to rotate, thereby disengaging from the fixation of the entire bolt post bottom, so that the entire bolt post is retracted into the column tube; when the hull rope pulls up the bolt post, the buoyancy principle of the bottom floating plate sinking into the water body as a whole due to the blockage of the buoy is utilized to realize the rotation of the rotating rod. The rotating rod rotates and disengages from the abutment with the movable cover, so that the bolt post located on the movable cover can be rotated, thereby facilitating the tension generated by the hull to pull the rope loop out from the top of the bolt post, thereby ensuring the safe movement of the hull in the lock chamber.

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 water level in 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 transition safely and orderly from one horizontal surface to another as the water level in the lock chamber increases or decreases.

[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 is a grease nozzle to add grease regularly, it is inconvenient to repair during the operation of the lock 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 peeled off after too long of a maintenance period, which can easily lead to some aquatic organisms clinging 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 the lock chamber. If the ship rope is not separated from the buoys in time, it is easy to cause the ship 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 bollard device to solve the problems raised in the above background art, such as the buoyant column being blocked in the track, causing the tethered hull to capsize or sink, and the problem that the buoy cannot perform self-cleaning protection.

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

[0007] A telescopically adjustable floating mooring post device includes a buoy, a fixed cover fixed to one side of the top of the buoy by bolts, and a movable cover rotatably connected inside the fixed cover. A liquid storage tank is provided in the buoy, and a piston column is slidably connected inside the liquid storage tank. One end of the piston column passes through the bottom of the buoy and is fixed to a floating plate by a strap.

[0008] The top of the liquid storage tank is connected with a connecting pipe, and a rotation adjustment mechanism is installed on the top of the float, and the rotation adjustment mechanism includes a fixed frame, a first gear, a tooth chain and a sealing cylinder. The fixed frame is fixed to the float and on one side of the fixed cover by spot welding, and the first gear is symmetrically and movably connected to the one side of the top of the fixed frame through a bearing. The three first gears are sleeved with a tooth chain, and a sealing cylinder is installed on the tooth chain. One side of the sealing cylinder is fixed to one side of the fixed frame by a bolt, and a piston plate is slidably connected to the sealing cylinder, and the two ends of the tooth 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 the abutment 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 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 and the movable cover, a buffer pad is adhered inside the column and at the top of the reset hole, a bolt is slidably connected inside the column, and one end of the bolt passes through the column and is slidably connected to the column.

[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 on the opposite side of the pressure plate and the movable cover. 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 rotated to connect the limiting plate, and the 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. 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 float are symmetrically connected to the first limiting wheel through bearings, the top of the float is symmetrically connected to the second limiting wheel through bearings, the bottom of the float is fixed with a bracket by bolts, and the second limiting wheel is symmetrically connected to 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 to a rotating drum, and a third gear is sleeved and fixed on the outer wall of the rotating drum, the second gear is meshed with the third gear, and an annular brush is fixed to one side of the rotating drum by bolts, and a brush rod is rotatably connected to one side of the bracket and is located in the rotating drum, and protrusions are symmetrically fixed on both sides of the brush rod by spot welding.

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

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

[0016] The hydraulic oil flows along the connecting pipe and enters the sealing cylinder, pushing the single-sided piston plate in the sealing cylinder to move to the other side, thereby driving the entire gear chain to rotate. The rotation of the gear chain drives the first gear to rotate, causing the rotating rod to rotate while disengaging 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, causing the entire bolt to face the rope loop tension angle, thereby causing the rope loop to separate from the buoy under the action of the hull tension.

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

[0018] The present invention specifically analyzes the specific engagement position of the buoy in the channel and the tension exerted by the hull rope on the bolt. When the hull rope pulls the bolt downward, the pressure plate on the bolt moves downward at the same time, and the abutment column connected to the pressure plate drives the limit plate to rotate, thereby releasing the fixation on the bottom of the entire bolt, so that the entire bolt is retracted into the column tube, and the rope loop at the top of the bolt successfully releases the buoy after no longer being fixed by the bolt. When the hull rope pulls the bolt upward, the buoyancy of the bottom floating plate as a whole sinks into the water body is increased by utilizing the principle that the buoyancy of the bottom floating plate increases due to the blockage of the buoy, so as to push the hydraulic oil in the liquid storage tank into the sealing cylinder, push the entire piston plate to move, and at the same time drive the gear chain to rotate, thereby realizing the rotation of the rotating rod. The rotation of the rotating rod releases the abutment against the movable cover, so that the bolt on the movable cover can rotate, thereby facilitating the tension generated by the hull to pull the rope loop out of the top of the bolt. The bolt is quickly released from the rope when the buoy is blocked in the channel, thereby avoiding the problem of the entire hull capsizing and ensuring 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. When 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.

[0029] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. 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 making creative efforts are within the scope of protection of the present invention.

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

[0031] Example 1:

[0032] like Figure 1 As shown in the figure, there are two hazards when the buoy (floating mooring column) located in the guide rail of the gate wall buoy is blocked and stuck. The buoy is stuck at the bottom of the gate. As the water level rises, the ship may be sunk; the buoy 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, when the buoy is blocked, the mooring rope is promptly separated from the buoy 1 to avoid the problem of the entire ship capsizing. In the specific operation, the entire buoy 1 is as shown in the figure. Figure 2 As shown, the buoy 1 is provided with a first limiting wheel 2 and a second limiting wheel 3 on the upper and lower sides, that is, a transverse wheel and a longitudinal wheel. In daily operation, 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 shafts and sleeves of the transverse and longitudinal wheels. The bolt 8 installed on the top of the buoy 1 has a relatively smooth surface and no limiting bend on the top. Therefore, when the buoy 1 is working normally, the bolt 8 installed on the top is required to maintain an angle of about 15 degrees with the ship deck, so that when the rope is operated, the rope loop generates a downward pulling force to avoid the problem of the bolt coming off.

[0033] However, when the entire buoy 1 is blocked above the liquid level, the hull will sink with the water level, 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, the bolt 8 needs to be explained. 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 anti-pillar 11 to press the spring 12 down. At this time, the anti-pillar 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. At this time, the tilted end of the limit plate 13 lifts the bolt column 8. When the entire bolt column 8 rises 6-7 cm, the limit plate 13 is separated from the contact with the bottom of the bolt column 8, and the bolt column 8 successfully falls to 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 provided at the bottom of the movable cover 5 and the column cylinder 6. The operator uses a column rod to insert the reset hole 15 into 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 cylinder 6 side is greater than that on the slide groove 10 side, so that the entire limit plate 13 can rotate automatically. The 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 cylinder 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-releasing and rope-releasing 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 float 1 is blocked in the track, as the liquid level rises, the entire float 20 will be immersed in the water. According to Archimedes' principle, buoyancy is related to the density of the liquid and the volume of the liquid displaced by the object. Therefore, the deeper the object is immersed before being completely immersed in the water, the greater the volume of the liquid displaced, the greater the buoyancy, and the greater the force applied. At this time, the float 20 drives the piston rod 19 to squeeze the hydraulic oil in the liquid storage tank 17 upward, causing the hydraulic oil to flow along the connecting pipe 18 into the sealing cylinder 216 in the rotation adjustment mechanism 21. 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 tooth chain 215, so that the tooth chain 215 starts to rotate on the first gear 212. The entire first gear 212 is divided into three and fixed on the fixing frame 211, and the fixing frame 211 is located in the buoy 1. Two of the first gears 212 are fixed with a rotating rod 213. When the first gear 212 rotates, it will drive the rotating rod 213 to rotate, as shown in FIG. 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, making the entire movable cover 5 unable to 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 direction of the pulling force of the rope gradually coincide with that of the rope, so that when the ship pulls the rope, the rope will be quickly pulled off the buoy 1. The rapid rope-removing operation of the bolt 8 when the buoy 1 is blocked in the channel can avoid the problem of the overall capsizing of the hull, thereby ensuring the safe movement of the hull in the lock chamber.

[0036] Example 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. The second limiting wheel 3 and the rotating drum 24 are movably connected to the entire bracket 22. An annular brush 26 is provided 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 engagement of the second gear 23 and the third gear 25. The rotation of the rotating drum 24 drives the annular brush 26 to rotate. Under the action of centrifugal force, the annular brush 26 begins to unfold and brush the surface of the horizontal wheel track to remove the water plants adhering 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 passes through 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, which may block the normal movement of the buoy 1, thereby reducing the probability of the buoy 1 being blocked in the track.

[0039] The emergency release design of the entire buoy 1 and the automatic cleaning 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 is as follows:

[0041] As the hull descends with the water level, the downward pulling force of the bolt 8 causes the rope to press the pressure plate 7 downward. At this time, the pressure plate 7 drives the stop column 11 to move downward in the chute 10 and contacts the limit plate 13 in the chute 10. The stop column 11 presses the limit plate 13 downward, and the entire limit plate 13 tilts up and lifts the bolt 8 in the column tube 6. After the bolt 8 rises to a height of 6-7 cm, it begins to fall as a whole without the contact of the limit plate 13, causing the entire bolt 8 to fall onto the buffer pad 16 at the bottom of the column tube 6. At this time, the rope loop tied to the bolt 8 is detached from the entire buoy 1 because it is no longer supported by the bolt 8.

[0042] The rising liquid level drives the hull up, and at this time the buoy 1 is stuck in the groove, so that the hull is pulled by the oblique upper part of the bolt 8. Since the buoy 1 begins to enter the bottom of the water 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 begins to push the piston rod 19 upward, so that the piston rod 19 pushes the hydraulic oil in the reservoir 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 the other side, thereby driving the entire tooth chain 215 to rotate. The rotation of the tooth 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 has no abutment on one side and begins to rotate in the fixed cover 4, so that the entire bolt 8 is directed towards the rope loop tension angle, so that the rope loop is separated from the buoy 1 under the action of the hull tension.

6. The adjustment method of the telescopically adjustable floating bollard device according to claim 5, characterized in that: The adjustment method of the telescopically adjustable floating bollard device is as follows: The pull-down operation is based on the downward pulling force of the bolt column (8) as the hull descends with the water surface, so that the rope body presses the pressure plate (7) downward. At this time, the pressure plate (7) drives the supporting column (11) to move downward in the chute (10) and contacts the limit plate (13) in the chute (10). The supporting column (11) presses the limit plate (13) downward, and the entire limit plate (13) rises 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 fall 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 buoy (1) is stuck in the channel, so that the hull is pulled obliquely upward based on the pulling force of the bolt column (8). Since the buoy (1) begins to enter the bottom of the water surface at this time, the bottom floating plate (20) 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 up, 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 tooth chain (215) to rotate. The rotation of the tooth 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 directed toward the rope loop tension angle, so that the rope loop is separated from the buoy (1) under the action of the hull tension.
