Description

Technical Field

[0001] The invention belongs to the technical field of ship equipment, and in particular relates to a ship rescue boat launching device. Background Art

[0002] Rescue boats are crucial equipment in maritime emergency rescue, which can respond quickly and deliver rescue personnel and equipment to the scene of the accident. Rescue boats are usually equipped with rescue boats. Marine rescue boats are important life-saving equipment when sailing at sea. They are used to quickly and safely launch rescue boats in emergency situations, so that lifeguards can take rescue boats to the accident area to carry out rescue, rescue trapped people to the rescue boats, and then return to the rescue boats together.

[0003] In the prior art, a rescue boat is usually installed on the deck side of a rescue ship, and connected to the rescue boat by a winch. When rescue is needed, the rescue boat is lowered to the sea surface by the winch. In order to make the lowering of the rescue boat stable and smooth, and to avoid the rescue boat from swinging violently due to the irregular movement of the rescue boat under the action of waves, a wave compensation device is usually also provided on the rescue ship. Wave compensation devices can be divided into active wave compensation devices and passive wave compensation devices, such as passive wave compensation devices. Passive wave compensation devices usually include the following forms: 1. An elastic damper or a passive heave compensator is set on the steel strand. Since the essence of wave compensation is to eliminate the rapid change of the tension of the steel strand, the load in this form is relatively stable and can eliminate the wave force in all directions of the main ship. However, this form requires the steel strand to be divided into two sections, and an elastic damper is set between the two sections of the steel strand. Dividing the steel strand into two sections is not conducive to the continuity of the steel strand, and its connection elastic damper is not conducive to the continuity of the steel strand. 1. The part of the damper is easy to wear and damage. If the elastic damper drops too low, it is easy to be affected by seawater infiltration. Moreover, the compensation capacity of only one elastic damper is general, and a single elastic damper wears quickly. 2. The winch is installed on the six-degree-of-freedom platform, and the elastic damper of the six-degree-of-freedom platform is used to compensate for the relative movement between the winch and the main ship. This form of passive compensation cannot quickly respond to the tension change of the steel strand, and there is a certain hysteresis. Therefore, the passive wave compensation effect in this form is general. 3. A mechanical energy storage structure is used as a passive wave compensation device. This structure usually uses components such as flywheels and springs to store and release energy. When the rescue ship rises and falls with the waves, the mechanical energy storage structure can absorb and store excess energy, and then release the energy when needed, thereby reducing the tension fluctuation of the steel strand. The advantage of this form is that the structure is relatively simple, does not require a complex electronic control system, and can adapt to wave motions of different frequencies to a certain extent. However, it also has some limitations. The energy storage and release capacity of the mechanical energy storage structure is limited, and it may not be able to fully compensate for larger wave forces. Moreover, after long-term use, mechanical parts are prone to wear, resulting in a decrease in energy storage and compensation effects, requiring regular maintenance and calibration; 4. A suspended gravity balance device is installed at the connection between the rescue boat and the steel strand. The device uses gravity to balance part of the wave force by configuring a balance block of appropriate weight. When the rescue boat moves due to waves, the balance block can move up and down within a certain range to offset the tension changes of part of the steel strand. This method is low-cost and relatively easy to install. However, the disadvantage is that the adjustment range of the balance block is limited, and it is difficult to accurately compensate for complex and changeable wave conditions, and the presence of the balance block may increase the additional load on the rescue boat and affect its handling performance.

[0004] To sum up, for the current rescue boat launching equipment, when using a passive wave compensation device, there is no passive wave compensation device that can well balance the steel strand tension compensation, steel strand continuity, reaction speed, and multi-directional compensation; based on this, the present invention designs a ship-borne rescue boat launching equipment, which adopts a passive wave compensation scheme. It can quickly respond to changes in steel strand tension without affecting the continuity of the steel strand, thereby realizing an effective and stable wave compensation scheme.

DETAILED DESCRIPTION

[0041] The following will be combined with the embodiments of the present invention Figure 1-Figure 10 , the technical solutions in the embodiments of the present invention are described clearly and completely. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Unless otherwise specified, the technical means used in the embodiments are conventional means well known to those skilled in the art. It should be noted that in the present invention, "outward" refers to the direction away from the deck, and inward refers to the direction toward the inside of the main hull 1. Unless otherwise specified in the present invention, "detachable connection" can be achieved by bolts, buckles, etc.

[0042] like Figure 1 , Figure 2 , a marine rescue boat launching device, comprising a bottom plate 2, an elastic damping mechanism 12 and a flipping mechanism;

[0043] The bottom plate 2 is fixed on the deck of the main hull 1;

[0044] The flipping mechanism comprises a linear drive device 3, a flipping rod 5, a bearing rod 13 and a winch 6; the bottom of the flipping rod 5 is rotatably connected to the bottom plate 2, the linear drive device 3 is arranged on the inner side of the flipping rod 5, the top of the linear drive device 3 is rotatably connected to the flipping rod 5, the bottom of the linear drive device 3 is rotatably connected to the bottom plate 2, and the outer side of the top of the flipping rod 5 is fixedly connected to one end of the bearing rod 13; the winch 6 is installed on the flipping rod 5, the rope body 8 of the winch 6 passes over the top of the bearing rod 13, and the end of the rope body 8 is used to connect to the rescue boat 9;

[0045] The flipping mechanism is provided with two and is located in the front and rear directions of the rescue boat 9, and the ends of the two rope bodies 8 are respectively used to connect the front and rear ends of the rescue boat 9; the elastic damping mechanism 12 is provided on the bearing rods 13 of the two flipping mechanisms; the rope bodies 8 are connected to the elastic damping mechanism 12, and the elastic damping mechanism 12 is used to smoothly lower the rescue boat 9, and the elastic damping mechanism 12 is located between the winch 6 and the rescue boat 9;

[0046] When the linear drive device 3 pushes the flip rod 5 outward to flip it, it is used to move the rescue boat 9 to the outside of the deck of the main hull 1; when the linear drive device 3 pushes the flip rod 5 inward to flip it, it is used to move the rescue boat 9 to above the deck of the main hull 1.

[0047] The main hull 1 is existing technology, such as various types of rescue vessels, ships, etc. During the driving process, the main hull 1 assumes the function of launching and transporting the rescue boat 9. The rescue boat 9 is usually used for emergency rescue missions at sea, and can respond quickly and arrive at the scene of the accident. Rescuers carry the rescue boat 9 to the sea surface and rush to the accident area with the ship to provide timely assistance to the people in distress and bring the trapped people back. The bottom plate 2 serves as the supporting foundation of the entire launching equipment and is fixedly installed on the deck of the main hull 1 to ensure the stability and reliability of the equipment. The linear drive device 3 serves as the power source of the flipping mechanism. By pushing the flipping action of the flipping rod 5, the rescue boat 9 can be moved between the inside and outside of the deck. As shown Figure 1 , is the launching and recovery state, at this time the flip rod 5 is set vertically, the rope body 8 and the rescue boat 9 are outside the deck, and the rescue boat 9 can be freely raised and lowered; Figure 2 , is the placement state of the rescue boat 9, at this time, the flip rod 5 is tilted, the linear drive device 3 is shortened, and the rescue boat 9 is fixedly placed on the deck and firmly supported by the support mechanism 4. The linear drive device 3 is a prior art, such as a hydraulic cylinder. The load-bearing rod 13 serves as the installation basis of the elastic damping mechanism 12, and also plays the role of supporting the rope body 8. The winch 6 is the main actuator for launching and recovering the rescue boat 9, and realizes the lifting and lowering movement of the rescue boat 9 by controlling the retraction and release of the rope body 8.

[0048] In addition, the flip rod 5 is preferably in an "L"-shaped structure, with its upper end bent outward and fixedly connected to the load-bearing rod 13. A plurality of support guide wheels 7 can be provided on the flip rod 5, and the support guide wheels 7 support the rope body 8, and the rope body 8 is preferably a steel strand; the elastic damping mechanism 12 can be provided in a shell to protect it from corrosion and stable operation. The rope body 8 and the rescue boat 9 can be connected by hooks and hanging rings, which is convenient and fast. The rope bodies 8 of the two flipping mechanisms are connected to the front and rear ends of the rescue boat 9 by hooks and hanging rings, realizing a double-point connection structure of the rescue boat 9, which is more stable.

[0049] like Figure 1As shown, in the process of launching the rescue boat 9, the main hull 1 is affected by the wave force, resulting in irregular sinking and swaying movements, which causes the tension of the rope body 8 to change; in this process, the elastic damping mechanism 12 is elastically displaced to offset the fluctuation of the tension of the rope body 8. The elastic damping mechanism 12 of the present invention is arranged on the rope body 8, which can promptly and quickly eliminate the tension change of the rope body 8, and does not divide the rope body 8 into two sections, which can maintain the continuity of the rope body 8 and improve the stability and reliability of the overall structure; the present invention fixes the elastic damping mechanism 12 on the bearing rod 13, and the position of the elastic damping mechanism 12 does not move with the rope body 8, which is convenient for maintenance and repair, and is not affected by seawater.

[0050] like Figure 1 , Figure 3 , Figure 6-Figure 8 The outward ends of the two bearing rods 13 are fixedly connected to the cross bar 10, and upper guide wheels 101 are respectively installed on the upper sides of both ends of the cross bar 10, and lower guide wheels 102 are respectively installed on the lower sides of both ends of the cross bar 10;

[0051] The rope 8 of the winch 6 passes over the upper guide wheel 101 and is connected to the elastic damping mechanism 12. The rope 8 extends from the elastic damping mechanism 12 and passes over the lower guide wheel 102. The rope 8 passing over the lower guide wheel 102 is vertically arranged and connected to the rescue boat 9. The cross bar 10 is perpendicular to the bearing bars 13 of the two elastic damping mechanisms 12.

[0052] Furthermore, the elastic damping mechanism 12 includes a damping friction rod 121, a first spring 125, a second spring 126 and an intermediate guide wheel 122;

[0053] The damping friction rod 121 is arranged on the two bearing rods 13, the two bearing rods 13 are respectively perpendicular to the damping friction rod 121, the damping friction rod 121 is slidably connected to the two bearing rods 13, the first spring 125 and the second spring 126 are both sleeved on the bearing rods 13, and the first spring 125 and the second spring 126 act on two sides of the damping friction rod 121 respectively;

[0054] The intermediate guide wheels 122 are respectively installed at both ends of the damping friction rod 121, and the intermediate guide wheel 122 is located below the upper guide wheel 101 and above the lower guide wheel 102; the rope body 8 passes around the upper guide wheel 101, the intermediate guide wheel 122 and the lower guide wheel 102 in sequence, and the part of the rope body 8 passing around the intermediate guide wheel 122 is in a "V" shape.

[0055] The cross bar 10 is perpendicular to the bearing bars 13 of the two flipping mechanisms. The damping friction bar 121 is parallel to the cross bar 10. The laying path of the rope body 8 is as follows: the rope body 8 comes out of the winch 6, is set on multiple supporting guide wheels 7, then passes over the upper guide wheel 101, passes from the lower guide wheel 101 to the upper part of the middle guide wheel 122, and then passes from the lower part of the middle guide wheel 122 to the upper part of the lower guide wheel 102, and finally connects to the rescue boat 9 from the outer side of the lower guide wheel 102 downward. The upper guide wheel 101 and the lower guide wheel 102 are symmetrically distributed on the upper and lower sides of the bearing bar 13, and the middle guide wheel 122 is located at the apex of the "V"-shaped structure.

[0056] The cross bar 10 realizes the synchronization of the flipping of the two flipping mechanisms. Through the "V"-shaped structure formed by the middle guide wheel 122, the upper guide wheel 101 and the lower guide wheel 102, when the tension of the rope body 8 changes due to wave force, the relative load weight of the rescue boat 9 increases or decreases, so the rope body 8 correspondingly pulls the middle guide wheel 122 to drive the damping friction rod 121 to move left and right along the axis of the load-bearing rod 13, and the first spring 125, the second spring 126 and the damping plate assembly 127 are used to eliminate the tension change of the rope body 8, thereby realizing the function of wave compensation. And under the layout of the "V"-shaped structure, the tension change of the rope body 8 can be transmitted to the first spring 125 and the second spring 126 in the form of axial force to a great extent, which has a good effect on compensating for wave force and eliminating the tension of the rope body 8.

[0057] It should be noted that the first spring 125 and the second spring 126 are both in a compressed state. Figure 1 In a static state, the damping friction rod 121 remains static under the action of the second spring 126. During the winding and unwinding process of the winch 6, the damping friction rod 121 moves slightly left and right under the action of the friction force of the rope body 8. The amount of movement is negligible, and under the action of the movement, the rope body 8 can be steadily raised and lowered to eliminate the influence of the unstable speed of the winch 6.

[0058] Furthermore, the elastic damping mechanism 12 also includes a front end plate 124, a rear end plate 123, a damping sheet assembly 127 and an intermediate rod 128;

[0059] The outer ends of the tops of the two flip rods 5 are fixedly connected to the two ends of the rear end plate 123, the rear end plate 123 is fixedly connected to the inner ends of the two bearing rods 13, the bearing rods 13 can slide through the front end plate 124, the damping friction rod 121 is located between the front end plate 124 and the rear end plate 123, the first spring 125 is located between the damping friction rod 121 and the rear end plate 123, and the second spring 126 is located between the damping friction rod 121 and the front end plate 124;

[0060] A plurality of intermediate rods 128 are fixedly connected to the rear end plate 123 , and the intermediate rods 128 pass through the damping friction rods 121 and the front end plate 124 in sequence. Friction damping is formed between the damping friction rods 121 and the intermediate rods 128 via the damping plate assembly 127 .

[0061] The cross bar 10, the front end plate 124, the rear end plate 123 and the damping friction rod 121 are parallel and perpendicular to the middle rod 128, the flip rod 5 and the bearing rod 13. The first spring 125 and the second spring 126 are sleeved on the bearing rod 13.

[0062] The damping source of the present invention is the friction damping between the damping plate assembly 127 and the intermediate rod 128. The multiple intermediate rods 128 and the damping plate assembly 127 can realize the function of increasing the damping effect, and by cooperating with the multiple first springs 125 and the second springs 126, the compensation capacity for wave force and the support capacity for the rescue boat 9 are improved. The front end plate 124 and the rear end plate 123 realize the limit constraint on the first spring 125 and the second spring 126.

[0063] like Figure 8 , Fig. 9 , the damping plate assembly 127 includes an upper pressing plate 1271, a lower pressing plate 1272 and a friction plate 1273;

[0064] The damping friction rod 121 is provided with a plurality of mounting through holes 1275, and the plurality of mounting through holes 1275 correspond one-to-one to the plurality of intermediate rods 128. The intermediate rods 128 pass through the corresponding mounting through holes 1275. The top of the mounting through hole 1275 is detachably connected to the upper pressure plate 1271, and the bottom of the mounting through hole 1275 is detachably connected to the lower pressure plate 1272. The bottom of the upper pressure plate 1271 and the top of the lower pressure plate 1272 are respectively fixedly connected with the friction plates 1273, and the two friction plates 1273 respectively abut against the upper and lower sides of the intermediate rod 128.

[0065] An elastic gasket 1274 is also provided between the upper pressing plate 1271, the lower pressing plate 1272 and the damping friction rod 121. The upper pressing plate 1271 and the lower pressing plate 1272 are fastened by bolts, so that the two friction plates 1273 generate an extrusion force on the middle rod 128, thereby forming friction damping. The structure of the upper pressing plate 1271, the lower pressing plate 1272 and the mounting through hole 1275 can realize the rapid replacement of the friction plate 1273. After long-term operation, the friction plate 1273 fails and the damping effect is poor, so the friction plate 1273 can be replaced in time. The design of the damping plate assembly 127 of the present invention can realize the function of rapid replacement of the friction plate 1273.

[0066] Furthermore, the first spring 125 and the second spring 126 are disposed on one or more of the intermediate rods 128 .

[0067] Furthermore, the bearing rod 13 is threadedly connected with an adjusting sleeve 131 , and the adjusting sleeve 131 presses the front end plate 124 .

[0068] By rotating the adjustment sleeve 131 , the position of the front end plate 124 can be adjusted, thereby adjusting the compression degree of the first spring 125 and the second spring 126 , thereby adjusting their elastic force, so as to adjust the movement amplitude of the damping friction rod 121 and adapt the friction damping size of the damping plate assembly 127 .

[0069] like Figure 1-Figure 4 The elastic damping mechanism 12 further includes a limiting mechanism 11, and the limiting mechanism 11 includes a fixing seat 111, a block 113, a connecting rod 114, an elastic telescopic component 116 and a pull rope 117;

[0070] The bottom of the damping friction rod 121 is rotatably connected to one end of the connecting rod 114, and the other end of the connecting rod 114 is fixedly connected to the clamping block 113; the fixing seat 111 is fixedly connected to the flip rod 5, and the fixing seat 111 is provided with an arc groove 112 facing the clamping block 113, and the arc groove 112 is provided on the rotation path of the clamping block 113, and the clamping block 113 is adapted to the arc groove 112; the connecting rod 114 and the flip rod 5 are connected by the pull rope 117, and the elastic telescopic component 116 is provided on the pull rope 117;

[0071] When the linear drive device 3 pushes the flip rod 5 outward to flip, the connecting rod 114 rotates in the direction away from the fixed seat 111 under the action of its own weight, and the blocking block 113 disengages from the arc groove 112; when the linear drive device 3 pushes the flip rod 5 inward to flip, the connecting rod 114 rotates in the direction of the fixed seat 111, and the blocking block 113 enters the arc groove 112 to limit the movement of the damping friction rod 121.

[0072] The main function of the limiting mechanism 11 is to constrain the damping friction rod 121 so that it cannot move. Figure 1 , Figure 3 During the deployment of the rescue boat 9, the wave compensation function needs to be utilized. In this state, the block 113 is disengaged from the arc groove 112, so the movement of the damping friction rod 121 is not affected. Figure 2 , Figure 4 When the rescue boat 9 is in the parking state, the flip rod 5 is tilted. Under the influence of this angle, the block 113 is inserted into the arc groove 112 to realize the constraint on the damping friction rod 121.

[0073] It should be noted that, during the movement of the damping friction rod 121, the connecting rod 114 moves along with it, and the pull rope 117 provides a degree of freedom for the movement of the connecting rod 114. Figure 1 In the state, the elastic expansion member 116 is in a stretched state; and Figure 2 In the state, since the angle of the connecting rod 114 changes, the length of the elastic telescopic component 116 becomes shorter, which can promote the swing amplitude of the connecting rod 114 and enable the block 113 to be inserted into the arc groove 112. An opening can be set on the arc groove 112 for the connecting rod 114 to pass through. The connecting rod 114 is preferably an "L"-shaped structure, and a counterweight block 115 can be fixedly connected to the top of the connecting rod 114. The purpose of the "L"-shaped structure and the counterweight block 115 is to change the center of gravity of the connecting rod 114 so that it can produce a larger swing amplitude when the flip rod 5 is tilted. The elastic telescopic component 116 is a prior art, such as a spring, and the pull rope 117 needs to be divided into two sections.

[0074] Furthermore, it also includes a support mechanism 4, which includes a telescopic rod 401, a fixing sleeve 402, an elastic column 403, a sphere 404 and a support plate 405;

[0075] The telescopic rod 401 is fixedly connected to the bottom plate 2, and the top of the telescopic rod 401 is detachably connected to the fixing sleeve 402. The fixing sleeve 402 is a hollow structure. The sphere 404 and the elastic column 403 are both arranged in the fixing sleeve 402. The sphere 404 is located above the elastic column 403. The inner diameter of the inner wall surface at the top of the fixing sleeve 402 is gradually reduced to limit the sphere 404. The sphere 404 is fixedly connected to the support plate 405 through the fixing rod; the sphere 404 is used to rotate so that the support plate 405 adapts to the bottom surface of the rescue boat 9;

[0076] The support mechanism 4 is provided with a plurality of members to support the rescue boat 9. The elastic column 403 may be a rubber column; preferably, there are four support mechanisms 4, which are evenly distributed below the rescue boat 9. The support plate 405 can be rotated arbitrarily to change its direction. The sphere 404 is pressed by the elastic column 403, and the rescue boat 9 presses the elastic column 403 through the support plate 405, generating elastic support, which can adapt to the different heights of the bottom of the rescue boat 9, and can also realize the shock absorption function for the placed rescue boat 9.

[0077] In specific implementation, when the rescue boat 9 is recovered, the personnel on the rescue boat 9 connect the hook and the ring, and the rescue boat 9 rises to Figure 1 The flip mechanism flips over to make the rescue boat 9 directly above the support mechanism 4, and then the rescue boat 9 is slowly lowered, while the telescopic rod 401 rises until the rescue boat 9 is supported to form a Figure 2When the rescue boat 9 needs to be launched, the telescopic rod 401 first descends and detaches from the rescue boat 9, and the overturning mechanism overturns again.

[0078] The embodiments described above are only descriptions of the preferred modes of the present invention and are not intended to limit the scope of the present invention. Without departing from the design spirit of the present invention, various deformations, modifications, and substitutions made to the technical solutions of the present invention by ordinary technicians in this field should all fall within the protection scope determined by the claims of the present invention.
