Description

Technical Field

[0001] The invention relates to the technical field of towing cable equipment, in particular to a three-drum hydraulic towing cable machine and a hydraulic control system thereof. Background Art

[0002] Among ship deck machinery, the towing winch is a relatively special lifting machinery with the characteristics of large towing capacity and wide adaptability. It is widely used in marine rescue ships, three-purpose work boats, tugboats and other ships.

[0003] The operation of the towing winch is to release the wire rope through the drum, and then brake the drum to achieve wire rope towing. In practical applications, the towing winch has a large load, which affects the safety of the tugboat, so it is particularly important to accurately display the load of the towed ship. Measuring the wire rope tension of the towing winch is an important task in the design of the towing winch.

[0004] With the development of the shipping industry, there are higher requirements for the operating efficiency of towing winches. Originally, towing winches could only tow one ship at a time during work, and the operating efficiency was low.

[0005] Based on the problems existing in the background technology, the present invention proposes a three-drum hydraulic towing winch with a cable arranger, which is equipped with double towing drums and a single anchoring drum, so that the towing winch can realize double-drum towing operations and double the towing efficiency. The independent active cable arranger makes the cable arrangement of the towing winch smoother.

[0006] In addition, the design of the force measuring pin of the towing cable solves the inaccurate shortcomings of the original force measuring device of the towing cable.

[0007] For example, Chinese patent drive system CN 117799765 brake clutch control system A discloses a three-drum multifunctional hydraulic towing winch, which includes a towing winch body, a power drive unit, an upper drum, a lower drum and a connecting unit; the power drive unit is arranged on the side of the towing winch body; the upper drum is arranged on the upper part of the towing winch body; the lower drum is arranged on the lower part of the towing winch body; the power drive unit drives the upper drum and the lower drum through the connecting unit. However, this technology has the following problems:

[0008] The above three-drum hydraulic towing winch is not equipped with an active cable arranger, which is not conducive to the arrangement of the wire rope recovered by the towing winch on the drum, and it is easy to cause the rope to be disordered, thereby reducing the life of the wire rope;

[0009] The drum of the above-mentioned three-drum hydraulic towing winch is not provided with a guide rope groove, and the wire rope is easily tangled when winding on the drum;

[0010] The above-mentioned towing crane force measuring device is installed on the tight side pin of the brake device. This measuring force is transmitted to the force measuring pin through the connecting rod mechanism after the brake is tightened. It does not directly reflect the tension of the towing crane wire rope and has low accuracy. In addition, due to the influence of the initial force of the brake cylinder, the force measuring pin displays the cylinder force when the towing crane is not working.

[0011] The most important point is that the three-drum hydraulic towing winch drive

[0012] For this purpose, we propose a three-drum hydraulic towing winch and its hydraulic control system. Summary of the invention

The three sets of sprockets are rotatably connected to two vertical frames and driven by a cable arrangement hydraulic motor. The cable arrangement guide rod is arranged between the chain sprocket assemblies. The sliding moving block on the cable arrangement guide rod adopts a split design.

[0026] A hydraulic control system, comprising:

[0027] Brake clutch control system, used to control the operation and stop of the anchor reel and towing reel;

[0030] Emergency release control system, used to respond quickly in emergency situations and cut off the driving force originally acting on the equipment;

[0051] The specific implementation of the present invention will be described below in conjunction with the accompanying drawings.

[0052] Example 1

[0053] like Figure 1-Figure 2 As shown, this embodiment discloses a three-drum hydraulic towing winch, which is mainly composed of a towing winch body and a cable arranger 2. The cable arranger 2 is divided into two parts, upper and lower, and three working areas for the three drums of the towing winch to work respectively. The towing winch body is mainly composed of three drums and a base 8, the anchor drum 3 is arranged at the front side, and the two towing drums 5 and 6 are arranged side by side at the rear side, and the anchor drum 3 and the two towing drums 5 and 6 are respectively located in the upper and lower layers, and correspond to the working area of ​​the cable arranger 2 to avoid mutual interference between the ropes. At the same time, a brake device 4 is provided on the anchor drum 3 and the two towing drums 5 and 6.

[0054] At the same time, the anchor hoisting drum 3 and the two towing drums 5 and 6 are connected to the same driving medium-speed shaft 14 through corresponding clutches 303 and 502, and a plurality of hydraulic motors 9 for driving are arranged on both sides of the driving medium-speed shaft 14.

[0055] In addition, the towing machine body also includes a base 8, a brake device 4 and an emergency release device 10.

[0056] Specifically, the base 8 is welded to the deck of the hull through the mounting feet 7 to improve the overall stability, and the anchor drum 3 and the two towing drums 5 and 6 are rotatably arranged on the base 8. At the same time, a force measuring pin 11 is also arranged on the base mounting feet 7 to measure the tension when the towing winch is working.

[0057] In this embodiment, a thrust block 301 for limiting the displacement of the three reels is also provided on the bearing seat.

[0058] The towing winch in this embodiment is directly welded to the hull deck via the mounting foot 7, and the mounting foot 7 is connected to the towing winch base 8 via a force measuring pin 11. When the towing winch is towing, the force measuring pin 11 in front of the towing winch is subjected to pressure, and the ordinary pin at the rear is subjected to tension. The support reaction force on the force measuring pin 11 can be calculated based on the principle of moment balance in classical mechanics, and conversely, the force on the towing winch wire rope 1 can be deduced.

[0059] The anchoring drum 3 in this embodiment is provided with a double-fold rope groove for regular arrangement of ropes and cables. At the same time, the anchoring drum 3 is provided with a dividing drum, which divides the entire drum into a working area and a cable storage area, ensuring that the working area is always working with high tension in the first layer and protecting the wire rope 1 in the cable storage area.

[0060] The anchor reel 3 in this embodiment is also provided with an anchor chain wheel 12 .

[0061] The two towing drums 5 and 6 in this embodiment are also provided with double folded line rope grooves to facilitate the arrangement of ropes, and the two towing drums 5 and 6 are respectively connected to the base 8 through corresponding bearing seats. At the same time, the two towing drums 5 and 6 are arranged side by side, so that the tugboat can achieve parallel towing, and the towing efficiency is twice that of the previous single towing, while also maintaining stability during parallel towing.

[0062] The brake device 4 in this embodiment includes a driving cylinder 401 , a driving connecting rod 402 and a brake belt 403 .

[0063] The brake band 403 has wear-resistant properties and is in controlled contact with the corresponding wheel hub. The other end of the brake band 403 is connected to the driving cylinder 401 through the driving connecting rod 402. Driven by the driving cylinder 401, the brake band 403 is in contact with the wheel hub, thereby achieving a braking effect.

[0064] The anchor hoisting drum 3 and the two towing drums 5 and 6 in this embodiment are provided with a cover 13, and the low-speed large and small gears are arranged in the cover 13 to improve safety.

[0065] The cable arranger 2 in this embodiment includes a stand 201, a chain sprocket assembly 202, a moving block 203 and a cable arranger support rod 204, which are used to achieve orderly arrangement of the cables on the three drums.

[0066] Specifically, the width of the stand 201 is close to the width of the base 8 , and needs to be at least larger than the width of the anchor-raising drum 3 or the sum of the widths of the two towing drums 5 , 6 .

[0067] In this embodiment, three groups of horizontally arranged chain sprocket assemblies 202 are arranged between the two vertical frames 201. The chain sprocket assembly 202 includes three sets of sprockets and chains. The three sets of sprockets are rotatably connected to the two vertical frames 201 and driven by the cable hydraulic motor. The sprockets span the corresponding two sprockets.

[0068] Each chain sprocket assembly 202 includes two chain sprocket assemblies, and a guide rod is arranged between the two chain sprocket assemblies, and the two ends of the guide rod are respectively connected to the two vertical frames 201, and the moving block 203 slidably connected to the guide rod adopts a split design, and the two chain sprocket assemblies are connected to the two moving blocks 203 in a one-to-one correspondence. At the same time, under the drive of the cable arrangement hydraulic motor, the relative displacement of the two moving blocks 203 can be achieved, thereby realizing the orderly arrangement of the cables.

[0069] At the same time, the cable support rod 204 is connected between the two vertical frames 201 to support the cable and divide two spaces in the vertical direction to facilitate the separation of the anchor drum 3 and the towing drums 5 and 6.

[0070] In order to facilitate the cable arrangement of the two side-by-side towing drums 5 and 6, a fixed frame is also provided in the middle of the two vertical frames 201, and two sets of horizontally arranged chain sprocket assemblies 202 at the lower end are respectively arranged between the fixed frame and the two vertical frames 201, thereby realizing the cable arrangement of the two side-by-side towing drums 5 and 6.

[0071] In this embodiment, by adding a cable arranger 2, the arrangement of the steel wire rope 1 is increased in order to extend the service life of the steel wire rope 1;

[0072] Design guiding double-folded rope grooves on the three drums of the towing winch, and cooperate with the cable arranger 2 to increase the neatness of the cable arrangement and extend the service life of the wire rope 1;

[0073] At the same time, the force measuring pin 11 sensor designed in this embodiment is installed on the base 7, which can directly measure the force of the towing machine and increase the accuracy of the force measurement.

[0074] Example 2

[0075] like Figure 4-Figure 8 As shown, this embodiment discloses a hydraulic control system for precise hydraulic control of the three-drum hydraulic towing machine in Embodiment 1.

[0076] like Figure 4 As shown, the system includes a brake clutch control system A; an emergency release control system B; a drive system C and a hydraulic pump station D to achieve efficient and safe management of the reel.

[0077] Specific as Figure 8 As shown, the hydraulic pump station D in this embodiment is the power source of the entire hydraulic system, responsible for converting electrical energy into hydraulic energy. Through the pumping action, the hydraulic pump station D delivers hydraulic oil to the drive device through the main pump group 904 and the auxiliary pump group 903. This is the basis for the towing winch system to work.

[0078] The hydraulic oil provided by the hydraulic pump station D first enters the main pump group 904, which is the core part of the hydraulic system and is responsible for delivering the hydraulic oil to various required working circuits, such as the hydraulic motor 9, to drive these devices to work.

[0079] The auxiliary pump group 903 is used as an auxiliary pump, mainly driving the brake, clutch and cable arranger 2 of the towing machine.

[0080] At the same time, the hydraulic pump station D also performs hydraulic control with the cable arrangement hydraulic motor. When the anchor hoisting drum 3 and the two towing drums 5 and 6 are reeling in and releasing cables, the corresponding cable arrangement hydraulic motor controls the chain sprocket assembly 202 and the moving block 203 to move synchronously, thereby achieving precise cable arrangement and improving the cable arrangement effect.

[0081] During the entire operation process, the hydraulic pump station D, the main pump group 904, the auxiliary pump group 903, the pressure gauge 902 and the alarm system 905 work together to ensure the stable, safe and efficient operation of the hydraulic system.

[0082] In summary, the hydraulic system is powered by the hydraulic pump station D, the main pump group 904 and the auxiliary pump group 903 are responsible for the delivery of hydraulic oil, the pressure gauge 902 performs pressure monitoring, and the alarm system 905 provides safety protection. The connection between the systems enables the hydraulic oil to be delivered to different working circuits, thereby jointly realizing the complex control function of the hydraulic system.

[0083] like Figure 7 As shown, the drive system C in this embodiment is the power source of the entire hydraulic system and is responsible for providing stable hydraulic energy to ensure that the system can operate continuously and efficiently.

[0084] The hydraulic motor 9 is an actuator in the system, responsible for converting the hydraulic energy provided by the drive system C into mechanical energy, thereby driving other mechanical devices in the system C. In this embodiment, there are multiple hydraulic motors 9, indicating that the system may involve multiple parallel drive circuits and can drive a larger load.

[0085] The proportional control valve 901 accurately adjusts the flow and pressure of the hydraulic oil according to the size and direction of the input signal. By adjusting the proportional control valve 901, the speed and torque of the hydraulic motor 9 can be accurately controlled to meet different work requirements.

[0086] like Figure 5 As shown, the brake clutch control system A in this embodiment is used to control the operation and stop of the anchor hoisting reel 3 and the towing reels 5 and 6;

[0087] The control of the anchor reel 3 is mainly achieved through the clutch 303 and the brake 302 .

[0088] When it is necessary to anchor, the anchor drum clutch 303 will be closed to connect it with the power system, allowing the anchor drum 3 to start rotating.

[0089] At the same time, the anchor drum brake 302 will be opened, and no braking force will be applied to the anchor drum 3, ensuring that the drum can rotate freely.

[0090] Operation completed: After the anchoring operation is completed, the brake 302 will be engaged and the clutch 303 will be disengaged, applying a braking force to the anchoring reel 3 to stop the rotation and keep it in a fixed position.

[0091] The control principle of the towing reels 5 and 6 is similar to that of the anchor reel 3 , and precise control thereof is mainly achieved through the clutch 502 and the brake 501 .

[0092] The clutch works, and when a towing operation is required, the towing drum clutch 502 is closed. This closing process connects the clutch to the power system, allowing the towing drums 5 and 6 to start rotating. Similar to the clutch 303 of the anchor reel, the closing of the towing drum clutch 502 is also through the control system issuing a command, and the hydraulic system drives the clutch to engage, thereby transmitting power.

[0093] At the same time, in order to ensure that the towing drum 5 can rotate freely, the towing drum brake 501 will be released. The release of the brake means that no braking force is applied to the towing drum 5, so that it can rotate smoothly under the drive of power. This step is a necessary preparation before the towing machine operation starts, ensuring that the drum can respond to the command of the control system and perform the expected action.

[0094] Operation completed: After the towing winch operation is completed, the clutch 502 will be disengaged and the brake 501 will be engaged. The disengagement of the clutch cuts off the connection between the power system and the towing winch drum 5, so that the drum is no longer driven by power. At the same time, the engagement of the brake applies a braking force to the towing winch drum 5, causing it to stop rotating and remain in a fixed position. This step ensures the safe end of the towing winch operation and prevents the drum from continuing to rotate without human control, which may cause safety hazards or equipment damage.

[0095] The brake clutch control system A also includes a brake emergency opening power source 503, which is used to independently open the brake in the event of failure of the auxiliary hydraulic system or in an emergency. In an emergency, if the braking force of the reel needs to be quickly released to avoid an accident, the brake emergency opening power source 503 will be activated. This system is usually connected to the auxiliary pump group 903 control system, but can work independently in an emergency to ensure the rapid opening of the brake.

[0096] Brake opens quickly: Once the emergency opening power source 503 is activated, it will quickly provide hydraulic power to open the brake, whether it is the anchor reel brake 302 or the towing reel brake 501. This allows the reel to rotate freely, thereby avoiding potential danger or equipment damage.

[0097] The hydraulic motors 9 of the drive system C correspond to the clutches and brakes of the brake clutch control system A and are connected to each other. When the hydraulic motor 9 works, the clutches or brakes in the brake clutch control system A are triggered, thereby achieving coordinated action of the system.

[0098] The hydraulic pump station D is connected to the brake clutch control system A and the drive system C at the same time. The hydraulic oil provided by the hydraulic pump station D can be delivered to the system brake clutch control system A and the system drive system C respectively, and the required hydraulic power is obtained through the hydraulic pump station D to realize their respective functions.

[0099] like Figure 6 As shown, the emergency release control system B in this embodiment mainly includes an emergency release device 10, which is operated by an air source delivered by the hull and is used for rapid response in an emergency. By opening the driving force originally acting on the driving medium-speed shaft 14, the driving medium-speed shaft 14 and the drum device (such as the first towing drum 5 or the second towing drum 6) are passively rotated without an active force, thereby quickly releasing the cable 1.

[0100] Pneumatic clutch control: In the system, both pneumatic clutches 304 are controlled by compressed air. When the corresponding control interface receives a control signal, compressed air enters the clutch 304 to make it engage and transmit power.

[0101] Air supply and stability: The air supply required by the system is provided by the ship, and the pressure is maintained between 8 and 10 bar. The stable air supply ensures that the pneumatic clutch 304 can be quickly and reliably engaged or released when needed.

[0102] Emergency release function realization: In an emergency, the emergency release control system B will start, cut off the air source or release the control signal, causing the pneumatic clutch 304 to release. After the clutch 304 is released, the anchor handling device 3 and the towing reel 5 and other equipment will no longer be constrained by the driving force and can rotate on their own to deal with the emergency.

[0103] The specific working principle and process of this embodiment are as follows:

[0104] Start-up phase: Hydraulic pump station D starts first to provide stable hydraulic energy for the entire system.

[0105] Power transmission stage: After being adjusted by the proportional control valve 901, the hydraulic energy is transmitted to each hydraulic motor 9. The hydraulic motor 9 converts the hydraulic energy into mechanical energy to drive other mechanical devices in the system C, such as the anchor reel 3 and the towing reel 5.

[0106] Clutch and brake control stage: According to the operation requirements, the control system will close or release the corresponding clutch 303, 502, and open or close the corresponding brake 302, 501 to achieve precise control of the reel.

[0107] Emergency release stage: In an emergency, the emergency release control system B will start, quickly open the pneumatic clutch 304, open the brake (such as 302 or 501), and ensure that the equipment cable 1 is quickly released to ensure the safety of the mother ship.

[0108] Monitoring and protection stage: The pressure gauge 902 monitors the oil pressure in the system in real time, and the alarm system 905 monitors the operating status of the entire system. Once the system is abnormal, the alarm system 905 will immediately sound an alarm to remind the operator to take timely measures.

[0109] Through this series of working principles and processes, the hydraulic control system can achieve precise control and safe management of the three-drum hydraulic towing winch, ensuring the stable operation of the equipment and the safety of the operators.

[0110] At the same time, in actual use, if the pressure demand is not high, an electric motor can be used instead of a hydraulic motor to improve transmission efficiency, reduce noise and reduce hydraulic oil pollution.
