Description

Technical Field

[0001] The present invention relates to the technical field of ship anchoring equipment, in particular to a telescopic anchor-raising device for a tugboat and a use method thereof. Background Art

[0002] Tugboats are vessels used to tow barges and ships. With the widespread adoption of new energy and technology, the mainstream development of modern tugboats has shifted towards green tugboats, which aim to reduce environmental pollution and achieve green and environmentally friendly operations. A hydrogen-fueled tugboat is a green tugboat, a new type of hydrogen-fueled tugboat. Its operating principle is to directly convert the chemical energy of hydrogen and oxygen into electrical energy through a hydrogen fuel cell. In a hydrogen fuel cell, hydrogen is decomposed into hydrogen ions and electrons under the action of an anode catalyst. The electrons form an electric current through an external circuit, providing power for the tugboat's propulsion system and onboard equipment. The hydrogen ions pass through a proton exchange membrane to the cathode, where they combine with oxygen to form water. This process produces almost no pollutants, achieving clean power generation. Hydrogen-fueled tugboats represent a new direction for green development in the port and shipping industry, offering advantages such as superior environmental performance, high energy conversion efficiency, and low noise pollution.

[0003] Furthermore, with the application of advanced technologies, modern green tugboats are gradually becoming intelligent. These technologies enable modern green tugboats to possess features such as autonomous navigation, automatic obstacle avoidance, and automatic attitude adjustment. However, while green and intelligent technologies have brought about rapid advancements in tugboat development, practical limitations remain. The intelligent devices on existing green tugboats cannot fully meet operational needs.

[0004] Before dropping anchor, it is necessary to use intelligent equipment to detect the water environment, and then set the chain length according to the water depth and geology. Then open the chain stopper, send the anchor chain to the predetermined length and make preparations before dropping anchor. After receiving the command, drop anchor. During this process, use the brake to loosen the anchor chain to the expected length, and finally close the chain stopper and brake the anchor chain. After the anchor is dropped, cover the anchor hole and lock it.

[0005] Among them, the restricted anchor chain is mostly formed by the combination of metal rings, which makes the metal anchor chain distinguished from horizontal rings and vertical rings. In order to adapt to the differences between horizontal and vertical rings, the anchoring device often has corresponding grooves in the anchor windlass placement wheel. However, in actual application, when the anchor chain is pulled or the chain slips, without the adjustment of intelligent equipment, the groove of the placement wheel will be difficult to fit tightly with the outer wall of the chain again, resulting in the horizontal and vertical rings in the anchor chain being squeezed against each other, causing damage to the chain. To address the above problems, the following solutions are proposed. Summary of the Invention

[0006] To solve the above technical problems, the present invention provides a telescopic anchor handling device for a tugboat, comprising a base, two driving motors being fixedly connected at both ends of the base, the output shafts of the two driving motors being fixedly connected to a rotating wheel, and a groove being formed on the outer wall of the rotating wheel;

[0007] The clamping mechanism includes an anchor chain, a mounting frame for clamping the anchor chain, a hydraulic pipe, a sliding rod, and a drive assembly for restraining the anchor chain;

[0008] The outer wall of the rotating wheel is fixedly connected to the inner wall of the mounting frame, the inner wall of the mounting frame is fixedly connected to the outer walls of the plurality of hydraulic pipes, and the inner walls of the plurality of hydraulic pipes are slidably connected with sliding rods.

[0009] Preferably, the driving assembly includes six hydraulic boxes fixedly connected to the side wall of the mounting frame, four piston plates are slidably connected to the inner wall of the six hydraulic boxes, and the six hydraulic boxes form a ring. A support rod is fixedly connected to the side wall of the piston plate, and a roller is rotatably connected to the inner wall of the support rod. Before use, the base is installed in the desired position, and then the anchor chain is placed on the outer wall of the rotating wheel through the groove, presenting a Figure 1 During this process, ensure that the hydraulic box is filled with hydraulic oil. When it is necessary to anchor, start the driving machine, and the driving machine drives several rollers to rotate together through the rotating wheel and the mounting frame.

[0010] Preferably, the drive assembly further comprises a spring 1 fixedly connected to a side of the piston plate away from the support rod 1, and an end of the spring 1 away from the support rod 1 is fixedly connected to an inner wall of the hydraulic box 1.

[0011] Preferably, the driving assembly also includes a support rod 2 fixedly connected to the inner wall of the base, a bevel ring is fixedly connected to the outer wall of the support rod 2, the inner wall of the hydraulic pipe is connected to the inner wall of the hydraulic box 1, and a sealing assembly is fixedly connected to the outer wall of the bevel ring. The outer wall of the roller 1 will always be in contact with the outer wall of the bevel ring. When the roller 1 reaches the inclined surface of the bevel ring, the roller 1 is affected by the inclined surface and slides along the inner wall of the hydraulic box 1 toward the mounting frame, forcing the hydraulic oil inside the hydraulic box 1 to enter the hydraulic pipe, forcing several sliding rods to slide outward along the corresponding inner walls of the hydraulic pipe, among which the side wall of the hydraulic box 1 is connected to ten hydraulic pipes, and some of the sliding rods in the ten hydraulic pipes will enter the inner wall of the vertical ring, presenting a Figure 5 The state of G, and part of the sliding rod will contact the outer wall of the transverse ring and appear as Figure 5 The anchor chain is in the middle F state, and the sliding rods at both ends enter the inner wall of the vertical ring at this time, which will limit the rotation of the anchor chain. Through the application of the above components, it is effectively guaranteed that when the anchor chain is retracted and released, the horizontal ring and the vertical ring in the anchor chain will not be squeezed against each other due to the mismatch of the card groove, which will cause the anchor chain to be damaged due to excessive pressure.

[0012] Preferably, the blocking assembly includes a support frame fixedly connected to the outer wall of the bevel ring, an end of the support frame away from the bevel ring is fixedly connected to a fixing ring, and an inclined groove is provided on the inner wall of the fixing ring.

[0013] Preferably, the blocking assembly also includes a plurality of sliding grooves provided on the side walls of the rotating wheel, wherein the inner walls of the plurality of sliding grooves are slidably connected to sliding plates, the side walls of the sliding plates are provided with through-hole grooves, and the inner wall of the mounting frame is fixedly connected to a buffer assembly. When the roller frame reaches the top of the rotating wheel, the fixed ring will force the roller frame to drive the sliding plate to move along the inner wall of the sliding groove toward the center of the rotating wheel. As the sliding plate moves, the through-hole groove and the hydraulic pipe will be misaligned, and the appropriate hydraulic pipe and the side wall of the sliding plate will form a closed state. Through the application of the above-mentioned components, it is ensured that when the sliding rod has not reached the left and right sides of the rotating wheel, the roller is blocked and cannot be reset, and it is ensured that when the rotating wheel drives the anchor chain for transmission through the sliding rod, the sliding rod will not cause the roller to accidentally contract due to external vibration, thereby affecting the efficiency of the equipment in retrieving or dropping the anchor chain.

[0014] Preferably, the blocking assembly also includes a roller frame fixedly connected to the side wall of the sliding plate, a spring 2 is fixedly connected to the side wall of the roller frame, an end of the spring 2 away from the roller frame is fixedly connected to the inner wall of the sliding groove, and an obstruction block is fixedly connected to the inner wall of the base. Utilizing the above-mentioned characteristics of the anchor chain rotation, a blocking assembly is provided inside the equipment. When the rotating wheel rotates, the rotating wheel will drive the roller frame to rotate synchronously, and at this time the roller frame will contact the outer wall of the fixed ring. When the roller frame is on the left and right sides of the rotating wheel, it will be affected by the elastic force of the spring 2. At this time, the through-hole groove will be in a state of overlap with the hydraulic pipe, so that the hydraulic oil inside the hydraulic box 1 can enter the hydraulic pipe through the through-hole groove.

[0015] Preferably, the buffer assembly includes a hydraulic cylinder fixedly connected to the inner wall of the mounting frame, a supporting round rod fixedly connected to the inner wall of the piston plate, and a piston disc fixedly connected to the end of the supporting round rod away from the piston plate. Three through-hole grooves 2 are opened on the side wall of the piston disc. Utilizing the characteristic that the above-mentioned piston plate slides along the inner wall of the hydraulic box 1, a spring 1 and a spring 2 are arranged inside the equipment. When the roller frame rotates to the left and right ends of the rotating wheel, the roller frame will contact the inner wall of the inclined groove. At this time, the spring 2 releases the pressure, so that the roller frame drives the through-hole groove to coincide with the hydraulic pipe through the sliding plate. At the same time, the roller 1 also reaches the inclined surface of the inclined ring and presents the following Figure 7 At this time, the spring 1 releases the pressure, causing the piston plate to slide outward along the inner wall of the hydraulic box 1, causing the sliding rod to reset along the inner wall of the hydraulic pipe. When the sliding rod reaches the left and right sides of the rotating wheel, several sliding rods can complete the reset, ensuring that the equipment can pull the anchor chain in an orderly manner.

[0016] Preferably, the buffer assembly also includes a right-angle groove formed at the inner wall of the through-hole groove No. 2, a rotating plate is rotatably connected to the inner wall of the through-hole groove No. 2, an arc spring is fixedly connected to the side wall of the rotating plate, and one end of the arc spring away from the rotating plate is fixedly connected to the inner wall of the through-hole groove No. 2. Taking advantage of the fact that the process of retracting and releasing the anchor chain of large ships is relatively slow, a buffer assembly is provided inside the equipment, and when the piston plate moves along the inner wall of the hydraulic box toward the mounting bracket, the piston plate drives the piston disc to move along the inner wall of the hydraulic cylinder toward the direction of the anchor chain through the supporting round rod, wherein the inner wall of the hydraulic cylinder is always filled with hydraulic oil, and is in a state as shown in FIG. Figure 12 When the piston plate is reset, the piston plate will move to the right along the inner wall of the hydraulic cylinder. At this time, the planes of the two rotating plates will contact the planes of the right-angle grooves, so that a gap will be formed between the two rotating plates. At this time, the hydraulic oil will be affected by the smaller gap and will directly slow down the reset speed of the piston plate, the supporting round rod and the piston plate, thereby indirectly controlling the reset speed of the sliding rod. Through the application of the above components, when the equipment unexpectedly causes the rotating wheel to stall and rotate, the rotating wheel will rotate faster than the reset speed of the sliding rod, so that the outer wall of the uncontracted sliding rod will contact the side wall of the obstruction block, so that the equipment can quickly limit the rotation of the rotating wheel in the early stage of stall, thereby avoiding subsequent greater economic losses.

[0017] A method for using a telescopic anchor handling device for a tugboat comprises the following steps:

[0018] S1: Install the equipment: Install the base at the desired location, then place the anchor chain through the groove on the outer wall of the rotating wheel, and ensure that the hydraulic tank is filled with hydraulic oil.

[0019] S2: Turn on the power: When it is necessary to drop anchor, start the driving machine, which drives several rollers to rotate together through the rotating wheel and the mounting frame to drop anchor.

[0020] The present invention has the following beneficial effects:

[0021] (1) The present invention utilizes the characteristics of the horizontal ring and vertical ring in the anchor chain, and sets a clamping mechanism and a driving component inside the device. Before use, the base is installed in the required position, and then the anchor chain is placed on the outer wall of the rotating wheel through the groove, showing Figure 1state, during this process, ensure that the hydraulic tank is filled with hydraulic oil. When it is necessary to anchor, start the driving machine, which is powered by hydrogen fuel. The driving machine drives several rollers to rotate together through the rotating wheel and the mounting frame. During this process, the outer wall of roller one will always be in contact with the outer wall of the bevel ring. When roller one reaches the inclined surface of the bevel ring, roller one is affected by the inclined surface and slides along the inner wall of hydraulic tank one toward the mounting frame, forcing the hydraulic oil inside hydraulic tank one to enter the hydraulic pipe, forcing several sliding rods to slide outward along the corresponding inner walls of hydraulic pipes, among which the side wall of hydraulic tank one is connected with ten hydraulic pipes, and some sliding rods in the ten hydraulic pipes will enter the inner wall of the vertical ring, presenting as shown below Figure 5 The state of G, and part of the sliding rod will contact the outer wall of the transverse ring and appear as Figure 5 The anchor chain is in the middle F state, and the sliding rods at both ends enter the inner wall of the vertical ring at this time to limit the rotation of the anchor chain. Through the application of the above components, it is effectively guaranteed that when the anchor chain is retracted and released, the horizontal ring and the vertical ring in the anchor chain will not be squeezed against each other due to the mismatch of the card groove, causing the anchor chain to be damaged due to excessive pressure, and the difference between the horizontal ring and the vertical ring can be effectively distinguished.

[0022] (2) The present invention utilizes the above-mentioned characteristic of anchor chain rotation and sets a blocking component inside the equipment. When the rotating wheel rotates, the rotating wheel will drive the roller frame to rotate synchronously, and at this time the roller frame will contact the outer wall of the fixed ring. When the roller frame is on the left and right sides of the rotating wheel, under the influence of the elastic force of the spring 2, the through-hole groove will be in a state of overlap with the hydraulic pipe, so that the hydraulic oil inside the hydraulic box 1 can enter the hydraulic pipe through the through-hole groove; when the roller frame reaches the top of the rotating wheel, the fixed ring will force the roller frame to drive the sliding plate to move along the inner wall of the sliding groove toward the center of the rotating wheel. As the sliding plate moves, the through-hole groove and the hydraulic pipe will be misaligned, and the hydraulic pipe and the side wall of the sliding plate will form a sealed state. Through the application of the above-mentioned components, it is ensured that when the sliding rod does not reach the left and right sides of the rotating wheel, the roller 1 is blocked and cannot be reset. It is ensured that when the rotating wheel drives the anchor chain to transmit through the sliding rod, the sliding rod will not cause the roller 1 to accidentally shrink due to external vibration, thereby affecting the efficiency of the equipment in reeling in or dropping the anchor chain.

[0023] (3) The present invention utilizes the characteristic that the piston plate slides along the inner wall of the hydraulic box. Spring 1 and spring 2 are provided inside the device. When the roller frame rotates to the left and right ends of the rotating wheel, the roller frame will contact the inner wall of the inclined groove. At this time, spring 2 releases the pressure, so that the roller frame drives the through-hole groove to coincide with the hydraulic pipe through the sliding plate. At the same time, roller 1 also reaches the inclined surface of the inclined ring and presents the following Figure 7At this time, the spring 1 releases the pressure, causing the piston plate to slide outward along the inner wall of the hydraulic box 1, causing the sliding rod to reset along the inner wall of the hydraulic pipe. When the sliding rod reaches the left and right sides of the rotating wheel, several sliding rods can complete the reset, ensuring that the equipment can pull the anchor chain in an orderly manner.

[0024] (4) The present invention utilizes the fact that the process of retracting and releasing anchor chains on large ships is relatively slow. A buffer component is provided inside the device. When the piston plate moves along the inner wall of the hydraulic box toward the mounting frame, the piston plate drives the piston disc to move along the inner wall of the hydraulic cylinder toward the anchor chain through the supporting round rod. The inner wall of the hydraulic cylinder is always filled with hydraulic oil, which is as follows: Figure 12 When the piston plate is reset, the piston plate will move to the right along the inner wall of the hydraulic cylinder. At this time, the planes of the two rotating plates will contact the planes of the right-angle grooves, so that a gap will be formed between the two rotating plates. At this time, the hydraulic oil will be affected by the smaller gap and will directly slow down the reset speed of the piston plate, the supporting rod and the piston plate, thereby indirectly controlling the reset speed of the sliding rod. Through the application of the above components, when the equipment encounters an accident and causes the rotating wheel to stall, the rotation speed of the rotating wheel will be faster than the reset speed of the sliding rod, so that the outer wall of the uncontracted sliding rod contacts the side wall of the obstruction block, so that the equipment can quickly limit the rotation of the rotating wheel in the early stage of stall. In addition, the clamping restriction of the anchor chain by the top sliding rod can prevent the anchor chain from losing control and falling into the sea, causing economic losses and polluting the marine environment.

DETAILED DESCRIPTION

[0042] 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.

[0043] For example 1, please refer to Figure 1 - Figure 7 The present invention is a telescopic anchor handling device for a tugboat, comprising a base 1, two driving motors 11 being fixedly connected at both ends of the base 1, the output shafts of the two driving motors 11 being fixedly connected to a rotating wheel 12, and a groove 13 being formed on the outer wall of the rotating wheel 12;

[0044] The clamping mechanism 2 includes an anchor chain 21, a mounting frame 22 for clamping the anchor chain 21, a hydraulic pipe 23, a sliding rod 24, and a driving assembly 3 for restraining the anchor chain 21;

[0045] The outer wall of the rotating wheel 12 is fixedly connected to the inner wall of the mounting frame 22 , and the inner wall of the mounting frame 22 is fixedly connected to the outer walls of a plurality of hydraulic pipes 23 . Sliding rods 24 are slidably connected to the inner walls of the plurality of hydraulic pipes 23 .

[0046] The driving assembly 3 includes six hydraulic boxes 31 fixedly connected to the side walls of the mounting frame 22. Four piston plates 32 are slidably connected to the inner walls of the six hydraulic boxes 31. The six hydraulic boxes 31 form a ring. A support rod 33 is fixedly connected to the side walls of the piston plates 32. A roller 34 is rotatably connected to the inner wall of the support rod 33. Before use, the base 1 is installed in the desired position, and then the anchor chain 21 is placed on the outer wall of the rotating wheel 12 through the groove 13, presenting the following Figure 1 During this process, the hydraulic box 31 is ensured to be filled with hydraulic oil. When anchoring is required, the driving machine 11 is started, and the driving machine 11 drives the plurality of rollers 34 to rotate in the same direction through the rotating wheel 12 and the mounting frame 22.

[0047] The driving assembly 3 also includes a spring 35 fixedly connected to the side of the piston plate 32 away from the support rod 33, and the end of the spring 35 away from the support rod 33 is fixedly connected to the inner wall of the hydraulic box 31.

[0048] The driving assembly 3 also includes a support rod 2 36 fixedly connected to the inner wall of the base 1, and a bevel ring 37 is fixedly connected to the outer wall of the support rod 2 36. The inner wall of the hydraulic pipe 23 is connected to the inner wall of the hydraulic box 1 31, and the outer wall of the bevel ring 37 is fixedly connected to the blocking assembly 4. The outer wall of the roller 1 34 will always be in contact with the outer wall of the bevel ring 37. When the roller 1 34 reaches the inclined surface of the bevel ring 37, the roller 1 34 is affected by the inclined surface and slides along the inner wall of the hydraulic box 1 31 toward the mounting bracket 22, forcing the hydraulic oil inside the hydraulic box 1 31 to enter the hydraulic pipe 23, forcing several sliding rods 24 to slide outward along the corresponding inner wall of the hydraulic pipe 23, among which the side wall of the hydraulic box 1 31 is connected to ten hydraulic pipes 23, and some of the sliding rods 24 in the ten hydraulic pipes 23 will enter the inner wall of the vertical ring, presenting as shown Figure 5 The state of G, and part of the sliding rod 24 will contact the outer wall of the transverse ring and appear as Figure 5 The anchor chain 21 is in the middle F state, and the sliding rods 24 at both ends enter the inner wall of the vertical ring to limit the rotation of the anchor chain 21. The application of the above components effectively ensures that when the anchor chain 21 is retracted or extended, the horizontal rings and the vertical rings in the anchor chain 21 will not be squeezed against each other due to the mismatch between the card grooves, causing the anchor chain 21 to be over-pressed and damaged.

[0049] For example 2, please refer to Figure 8 - Figure 14 The present invention is a telescopic anchor-handling device for a tugboat. Based on the first embodiment, the blocking assembly 4 includes a support frame 41 fixedly connected to the outer wall of the bevel ring 37. The end of the support frame 41 away from the bevel ring 37 is fixedly connected to a fixing ring 42, and an inclined groove 43 is provided on the inner wall of the fixing ring 42.

[0050] When the wheel 12 is at the top, the fixed ring 42 will force the roller frame 47 to drive the sliding plate 45 to move along the inner wall of the sliding groove 44 toward the center of the rotating wheel 12. As the sliding plate 45 moves, the through-hole groove 46 and the hydraulic pipe 23 will be misaligned, and the hydraulic pipe 23 and the side wall of the sliding plate 45 will form a sealed state. Through the application of the above components, it is ensured that when the sliding rod 24 does not reach the left and right sides of the rotating wheel 12, the roller 134 is blocked and cannot be reset, so as to ensure that when the rotating wheel 12 drives the anchor chain 21 to be transmitted through the sliding rod 24, the sliding rod 24 will not cause the roller 134 to accidentally retract due to external vibration, thereby affecting the efficiency of the equipment in reeling in or dropping the anchor chain 21.

[0051] The blocking assembly 4 also includes a roller frame 47 fixedly connected to the side wall of the sliding plate 45, and a spring 2 48 is fixedly connected to the side wall of the roller frame 47. The end of the spring 2 48 away from the roller frame 47 is fixedly connected to the inner wall of the sliding groove 44, and an obstruction block 49 is fixedly connected to the inner wall of the base 1. Utilizing the rotation characteristics of the above-mentioned anchor chain 21, a blocking assembly 4 is provided inside the equipment. When the rotating wheel 12 rotates, the rotating wheel 12 will drive the roller frame 47 to rotate synchronously, and at this time the roller frame 47 will contact the outer wall of the fixed ring 42. When the roller frame 47 is on the left and right sides of the rotating wheel 12, it is affected by the elastic force of the spring 2 48. At this time, the through-hole groove 46 will be in a state of overlap with the hydraulic pipe 23, so that the hydraulic oil in the hydraulic box 1 31 can enter the hydraulic pipe 23 through the through-hole groove 46.

[0052] The buffer assembly 5 includes a hydraulic cylinder 51 fixedly connected to the inner wall of the mounting frame 22, a supporting round rod 52 fixedly connected to the inner wall of the piston plate 32, and a piston disc 53 fixedly connected to the end of the supporting round rod 52 away from the piston plate 32. Three through-hole grooves 54 are opened on the side wall of the piston disc 53. Taking advantage of the characteristic that the piston plate 32 slides along the inner wall of the hydraulic box 1 31, a spring 1 35 and a spring 2 48 are arranged inside the equipment. When the roller frame 47 rotates to the left and right ends of the rotating wheel 12, the roller frame 47 will contact the inner wall of the inclined groove 43. At this time, the spring 2 48 releases the pressure, so that the roller frame 47 drives the through-hole groove 46 to coincide with the hydraulic pipe 23 through the sliding plate 45. At the same time, the roller 1 34 also reaches the inclined surface of the bevel ring 37 and presents the following Figure 7 At this time, the spring 1 35 releases the pressure, causing the piston plate 32 to slide outward along the inner wall of the hydraulic box 1 31, so that the sliding rod 24 is reset along the inner wall of the hydraulic pipe 23. When the sliding rod 24 reaches the left and right sides of the rotating wheel 12, several sliding rods 24 can complete the reset, ensuring that the equipment can pull the anchor chain 21 in an orderly manner.

[0053] The buffer assembly 5 also includes a right-angle groove 55 formed on the inner wall of the through-hole groove 2 54, a rotating plate 56 is rotatably connected to the inner wall of the through-hole groove 2 54, and an arc spring 57 is fixedly connected to the side wall of the rotating plate 56. The end of the arc spring 57 away from the rotating plate 56 is fixedly connected to the inner wall of the through-hole groove 2 54. Taking advantage of the fact that the process of retracting and releasing the anchor chain of large ships is relatively slow, a buffer assembly 5 is provided inside the equipment. When the piston plate 32 moves along the inner wall of the hydraulic box 1 31 toward the mounting bracket 22, the piston plate 32 drives the piston disc 53 to move along the inner wall of the hydraulic cylinder 51 toward the anchor chain 21 through the supporting round rod 52, wherein the inner wall of the hydraulic cylinder 51 is always filled with hydraulic oil, presenting a shape as shown in FIG. Figure 12When the piston plate 53 moves to the left along the inner wall of the hydraulic cylinder 51, the hydraulic oil on the left side of the piston plate 53 will reach the right side of the piston plate 53 through the through-hole groove 2 54. During this process, the hydraulic oil will push the rotating plate 56 to tilt to the right with the connection point as the center. When the external component drives the piston plate 32 to reset, the piston plate 53 will move to the right along the inner wall of the hydraulic cylinder 51. At this time, the planes of the two rotating plates 56 contact the planes of the right-angle groove 55, so that a gap will be formed between the two rotating plates 56. At this time, the hydraulic oil will be affected by the smaller gap and will directly slow down the reset speed of the piston plate 53, the supporting round rod 52 and the piston plate 32, thereby indirectly controlling the reset speed of the sliding rod 24. Through the application of the above components, when the equipment unexpectedly causes the rotating wheel 12 to stall, the rotation speed of the rotating wheel 12 will be faster than the reset speed of the sliding rod 24, so that the outer wall of the unretracted sliding rod 24 contacts the side wall of the obstruction block 49, so that the equipment can quickly limit the rotation of the rotating wheel 12 in the early stage of stall, thereby avoiding subsequent greater economic losses.

[0054] The method for using the telescopic anchor handling device for a tugboat includes the following steps:

[0055] S1: Install the equipment: Install the base 1 at the desired location, then place the anchor chain 21 on the outer wall of the rotating wheel 12 through the groove 13, and ensure that the hydraulic tank 31 is filled with hydraulic oil.

[0056] S2: Turn on the power: When it is necessary to drop anchor, start the driving machine 11, which drives the plurality of rollers 34 to rotate in the same direction through the rotating wheel 12 and the mounting frame 22 to drop anchor.

[0057] A specific application of this embodiment is: before use, the base 1 is installed at the desired position, and then the anchor chain 21 is placed on the outer wall of the rotating wheel 12 through the groove 13, showing the following Figure 1 The hydraulic oil in the hydraulic tank 31 is forced into the hydraulic pipe 23, forcing the plurality of sliding rods 24 to slide outward along the corresponding inner walls of the hydraulic pipes 23. The side walls of the hydraulic tank 31 are connected to the ten hydraulic pipes 23, and some of the sliding rods 24 in the ten hydraulic pipes 23 will enter the inner wall of the vertical ring, presenting a Figure 5 The state of G, and part of the sliding rod 24 will contact the outer wall of the transverse ring and appear as Figure 5The anchor chain 21 is in the middle F state, and the sliding rods 24 at both ends enter the inner wall of the vertical ring to limit the rotation of the anchor chain 21. The application of the above components effectively ensures that when the anchor chain 21 is retracted or extended, the horizontal rings and the vertical rings in the anchor chain 21 will not be squeezed against each other due to the mismatch between the card grooves, causing the anchor chain 21 to be over-pressed and damaged.

[0058] Taking advantage of the rotation characteristics of the above-mentioned anchor chain 21, a blocking component 4 is provided inside the equipment. When the rotating wheel 12 rotates, the rotating wheel 12 will drive the roller frame 47 to rotate synchronously, and at this time the roller frame 47 will contact the outer wall of the fixed ring 42. When the roller frame 47 is on the left and right sides of the rotating wheel 12, under the influence of the elastic force of the spring 2 48, the through-hole groove 46 will be in a state of overlap with the hydraulic pipe 23, so that the hydraulic oil in the hydraulic box 31 can enter the hydraulic pipe 23 through the through-hole groove 46; when the roller frame 47 reaches the top of the rotating wheel 12, the fixed ring 42 will force the roller frame 47 to bring The movable sliding plate 45 moves along the inner wall of the sliding groove 44 toward the center of the rotating wheel 12. As the sliding plate 45 moves, the through-hole groove 46 and the hydraulic pipe 23 will be misaligned, and the hydraulic pipe 23 and the side wall of the sliding plate 45 will form a sealed state. Through the application of the above components, it is ensured that when the sliding rod 24 has not reached the left and right sides of the rotating wheel 12, the roller 134 is blocked and cannot be reset. When the rotating wheel 12 drives the anchor chain 21 for transmission through the sliding rod 24, the sliding rod 24 will not cause the roller 134 to accidentally contract due to external vibration, thereby affecting the efficiency of the equipment in reeling in or dropping anchor on the anchor chain 21.

[0059] Taking advantage of the fact that the piston plate 32 slides along the inner wall of the hydraulic box 1 31, a spring 1 35 and a spring 2 48 are provided inside the device. When the roller frame 47 rotates to the left and right ends of the rotating wheel 12, the roller frame 47 will contact the inner wall of the inclined groove 43. At this time, the spring 2 48 releases the pressure, so that the roller frame 47 drives the through-hole groove 46 to coincide with the hydraulic pipe 23 through the sliding plate 45. At the same time, the roller 1 34 also reaches the inclined surface of the inclined ring 37 and presents the following Figure 7 At this time, the spring 1 35 releases the pressure, causing the piston plate 32 to slide outward along the inner wall of the hydraulic box 1 31, so that the sliding rod 24 is reset along the inner wall of the hydraulic pipe 23. When the sliding rod 24 reaches the left and right sides of the rotating wheel 12, several sliding rods 24 can complete the reset, ensuring that the equipment can pull the anchor chain 21 in an orderly manner.

[0060] Taking advantage of the fact that the process of retracting and releasing anchor chains on large ships is relatively slow, a buffer assembly 5 is provided inside the device. When the piston plate 32 moves along the inner wall of the hydraulic box 31 toward the mounting frame 22, the piston plate 32 drives the piston disc 53 to move along the inner wall of the hydraulic cylinder 51 toward the anchor chain 21 through the supporting round rod 52, wherein the inner wall of the hydraulic cylinder 51 is always filled with hydraulic oil, and the hydraulic cylinder 51 is in a state of being as shown in FIG. Figure 12In the state, when the piston plate 53 moves to the left along the inner wall of the hydraulic cylinder 51, the hydraulic oil on the left side of the piston plate 53 will reach the right side of the piston plate 53 through the through-hole groove 2 54. In this process, the hydraulic oil will push the rotating plate 56 to tilt to the right with the connection point as the center; and when the external component drives the piston plate 32 to return to its original position, the piston plate 53 will move to the right along the inner wall of the hydraulic cylinder 51. At this time, the planes of the two rotating plates 56 will contact the planes of the right-angle groove 55, so that a gap will be formed between the two rotating plates 56. At this time, the hydraulic oil is affected by the above The impact of the smaller gap will directly slow down the reset speed of the piston disc 53, the supporting rod 52 and the piston plate 32, thereby indirectly controlling the reset speed of the sliding rod 24. Through the application of the above-mentioned components, when an accident occurs in the equipment and causes the rotating wheel 12 to stall, the rotation speed of the rotating wheel 12 will be faster than the reset speed of the sliding rod 24, so that the outer wall of the uncontracted sliding rod 24 contacts the side wall of the obstruction block 49, so that the equipment can quickly limit the rotation of the rotating wheel 12 in the early stage of stall, avoiding greater economic losses in the subsequent stalled state.
