Description

Technical Field

[0001] The invention belongs to the technical field of ship accessories, and in particular relates to a multifunctional ship warping device. Background Art

[0002] Ship is a general term for various vessels. Ship is a means of transportation that can sail or anchor in waters for transportation or operations. It has different technical performance, equipment and structural types according to different usage requirements. Ships play an irreplaceable and important role in human social life. Ships undertake various purposes such as personnel and cargo transportation, military, scientific investigation, etc., and the sizes of ships are also different. Large ships are slow but have strong transportation capacity. Although small ships have smaller transportation capacity, they have fast travel speeds. For example, speedboats are a common small water transportation tool, known for their high speed, flexibility and maneuverability. The high speed, flexibility and maneuverability of speedboats are mainly achieved by the propeller driven by the engine installed at the tail. While driving, the speedboat can tilt the propeller upward to increase the height of the bow, thereby reducing resistance; and turning the propeller downward can lower the height of the bow, making the hull travel more smoothly, and the change of propeller angle is achieved by such as Fig.13 This is achieved by the tilting device shown, wherein the mounting frame 4 is connected to the hull, and the engine is mounted on the connecting plate 102. The angle between the connecting plate 102 and the mounting frame 4 is changed by the telescopic device 103 to achieve the change of the propeller angle.

[0003] At present, there are two types of marine tilting devices, namely manual tilting devices and automatic tilting devices. When the hull is traveling at high speed, the propeller will be subjected to a large reaction force, so the manual tilting device is more laborious to use and difficult to operate. The automatic tilting device includes electric and hydraulic devices. The hydraulic tilting device has a high maintenance cost due to its complex structure, so most speedboats use electric tilting devices more frequently. However, the existing electric tilting devices can only provide support when the tilting device is raised to the maximum angle, while the speedboat needs to adjust the propeller angle according to actual conditions during driving. Generally, after the adjustment is completed, it can only be supported by the electric push rod structure, and the electric push rod will be easily damaged if it is subjected to the force transmitted from the propeller for a long time.

[0004] At the same time, the connection mechanism between the existing lifter and the speedboat is relatively complicated. One part requires drilling holes on the hull and then installing it with bolts. Although the other part adopts a clamping structure for installation, the clamping structure needs to be clamped and fixed by turning the screw. The installation process is relatively cumbersome and requires the cooperation of multiple people to complete the installation. Moreover, as the lifter continues to work, it will become loose, affecting the safety of the speedboat.

[0005] Therefore need us to design a kind of multifunctional ship warping device to solve these problems. Summary of the invention

[0006] The problem to be solved by the present invention is to provide a multifunctional ship warping device, which solves the problem that the existing warping device has a single structure and is complicated and cumbersome to install and fix.

[0007] In order to solve the above technical problems, the technical solution adopted by the present invention is: A multifunctional ship lifter includes a lift assembly, which is composed of a mounting plate and a connecting plate hinged to each other and a telescopic device respectively connected to the mounting plate and the connecting plate. The lift assembly is connected to the hull through the mounting plate, and a support assembly is arranged between the connecting plate and the mounting plate. When the connecting plate and the mounting plate rotate relative to each other, the support assembly is used to support the mounting plate and the connecting plate at different angles.

[0011] With such arrangement, the spring can be used to push the telescopic column to always keep in contact with the rotating block, and when the clamping block enters the fixing groove and the reset groove, it can be correspondingly inserted into the clamping groove and the positioning groove, so that the clamping block is always in the correct position.

[0012] Preferably, a fixing component is also provided on the mounting plate, and the fixing component is used to connect the lifting component to the hull.

[0013] Furthermore, the fixing assembly includes a main frame, a group of driving rods are slidably provided on relative inner walls of the main frame, the mounting plate is located between the two driving rods and fixedly connected to the driving rods, the driving rods are provided with driving teeth, a limiting frame is fixedly provided on the top of the main frame, a cross bar is slidably provided in the limiting frame, the cross bar is provided with driven teeth, the driven teeth are inclined and matched with the driving teeth, a fixing rod is fixedly provided on each cross bar, and the two cross bars are connected by a connecting rod.

[0014] With such arrangement, the main frame and the fixing rod can be quickly clamped on the hull by sliding the cross rod, and loosening can be prevented by inserting the driving rod and utilizing the lifting assembly and the gravity of the engine.

[0015] Furthermore, the driven teeth are respectively arranged on opposite surfaces of the two cross bars, and the driving teeth are respectively arranged on surfaces opposite to the driven teeth. The inclination direction and inclination angle A of the driving teeth and the driven teeth are the same, and 75°<A<85°.

[0016] With such arrangement, the relative sliding smoothness of the driving rod and the cross bar can be ensured and the moving distance of the cross bar after the driving rod is inserted can be adjusted by limiting the angles of the driving teeth and the driven teeth.

[0017] Furthermore, guide grooves are respectively arranged on the opposite inner walls of the main frame, and the two driving rods are respectively slidably arranged in the guide grooves.

[0018] With this arrangement, the sliding direction of the driving rod is limited.

[0022] With such a configuration, the cooperation between the end of the fixing bolt and the inclined surface of the anti-loosening groove can further push the cross bar to move and prevent the cross bar from loosening. At the same time, by limiting the angle between the inclined surface of the anti-loosening groove and the axis of the fixing bolt, the sliding effect after the sliding fixing bolt contacts the inclined surface of the anti-loosening groove can be ensured.

The gravity of the lifting component and the engine is used to clamp the fixing component on the ship more firmly, and loosening can be prevented at the same time. The installation stability is further improved by the cooperation between the anti-loosening groove and the fixing bolt. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] The present invention will be further described below in conjunction with the accompanying drawings: like Figure 1 and Figure 2 As shown, a multifunctional ship lifter includes a lift assembly 1, which is composed of a mounting plate 101 and a connecting plate 102 hinged to each other, and a telescopic device 103 respectively connected to the mounting plate 101 and the connecting plate 102, wherein the mounting plate 101 is equivalent to Fig.13 The mounting frame 4 in the prior art is shown, and the lifting assembly 1 is connected to the hull through the mounting plate 101, and a support assembly 2 is arranged between the connecting plate 102 and the mounting plate 101. When the connecting plate 102 and the mounting plate 101 rotate relative to each other, the support assembly 2 is used to support the mounting plate 101 and the connecting plate 102 at different angles.

[0031] like Figure 4-Figure 8 As shown, the support assembly 2 includes a support frame 201 connected to the mounting plate 101, a slide groove 209 is provided on the support frame 201, a plurality of slots 202 are provided on one side wall of the slide groove 209, a reset slot 203 is provided at one end of the slide groove 209, and a fixing slot 204 is provided at the other end, a slide rod 205 is inserted into the support frame 201, and a rotating block 211 is provided at the end of the slide rod 205 located in the support frame 201, and a positioning slot 208, The clamping groove 207 and the clamping block 206, the clamping block 206 matches the clamping groove 202, and a positioning device 210 is also provided on the slide bar 205 on one side of the rotating block 211. The positioning device 210 is connected with the positioning groove 208 and the clamping groove 207 in cooperation with each other. In this way, the multiple clamping grooves 202 in the slide groove 209 on the support frame 201 and the clamping block 206 on the slide bar 205 can be used to support the mounting plate 101 and the connecting plate 102 at different angles.

[0032] like Fig. 9 As shown, the positioning device 210 includes a fixed block 2101, a through hole 2105 is provided on the fixed block 2101, a spring 2103, a telescopic column 2102 and an adjusting rod 2104 are provided in the through hole 2105, the spring 2103 is located between the adjusting rod 2104 and the telescopic column 2102, one end of the telescopic column 2102 is connected to the spring 2103, and the other end extends from the through hole 2105 and cooperates with the clamping groove 207 and the positioning groove 208, and the adjusting rod 2104 and the fixed block 2101 are connected to each other. The fixed block 2101 is connected by threaded fitting, one end of the adjusting rod 2104 is connected to the spring 2103, and the other end is extended from the through hole 2105 and fixedly provided with the adjusting block 2106. In this way, the spring 2103 can push the telescopic column 2102 to always keep in contact with the rotating block 211, and when the clamping block 206 enters the fixing groove 204 and the reset groove 203, it can be correspondingly inserted into the clamping groove 207 and the positioning groove 208, so that the clamping block 206 is always in the correct position.

[0033] like Figure 3 As shown, a fixing component 3 is also provided on the mounting plate 101, and the fixing component 3 is used to connect the lifting component 1 to the hull.

[0034] Specifically, the fixing assembly 3 includes a main frame 301, a group of driving rods 302 are slidably provided on the relative inner walls of the main frame 301, the mounting plate 101 is located between the two driving rods 302 and fixedly connected to the driving rods 302, a driving tooth 303 is provided on the driving rod 302, a limiting frame 307 is fixedly provided on the top of the main frame 301, a cross bar 305 is slidably provided in the limiting frame 307, a driven tooth 304 is provided on the cross bar 305, the driven tooth 304 and the driving tooth 303 are tilted and matched with each other, a fixing rod 310 is fixedly provided on each cross bar 305, and the two cross bars 305 are connected by a connecting rod 311, such a configuration can realize the rapid clamping of the main frame 301 and the fixing rod 310 on the hull by sliding the cross bar 305, and prevent loosening by inserting the driving rod 302 and utilizing the lifting assembly 1 and the gravity of the engine.

[0035] Specifically, the driven teeth 304 are respectively arranged on the opposite surfaces of the two cross bars 305, and the driving teeth 303 are respectively arranged on the surfaces opposite to the driven teeth 304. The inclination direction and inclination angle A of the driving teeth 303 and the driven teeth 304 are the same, and 75°<A<85°. Such an arrangement can ensure the relative sliding smoothness of the driving rod 302 and the cross bar 305 and adjust the moving distance of the driving rod 302 after the insertion of the cross bar 305 by limiting the angles of the driving teeth 303 and the driven teeth 304.

[0036] Preferably, guide grooves 308 are respectively arranged on the opposite inner walls of the main frame 301 , and the two driving rods 302 are respectively slidably arranged in the guide grooves 308 , so that the sliding direction of the driving rods 302 can be limited.

[0037] Preferably, a reinforcing plate 306 is fixedly disposed on the cross bar 305 and the fixing rod 310 , so that the fixing rod 310 can be prevented from bending and deforming after being subjected to force.

[0038] Preferably, a fixing bolt 309 is also provided through the limit frame 307, and the fixing bolt 309 is connected to the limit frame 307 by a thread, and an anti-loosening groove 312 is provided on the cross bar 305, and the surface opposite to the fixing bolt 309 in the anti-loosening groove 312 is inclined, and the angle between the inclined surface in the anti-loosening groove 312 and the axis of the fixing bolt 309 is B, and 55°<B<60°. Such a setting can further promote the movement of the cross bar 305 through the cooperation between the end of the fixing bolt 309 and the inclined surface of the anti-loosening groove 312 to prevent the cross bar 305 from loosening. At the same time, by limiting the angle between the inclined surface of the anti-loosening groove 312 and the axis of the fixing bolt 309, the sliding effect after the sliding fixing bolt 309 contacts the inclined surface of the anti-loosening groove 312 can be guaranteed.

[0039] Working process of this embodiment: Before using this device, it is necessary to first pull out the lifting assembly 1 together with the driving rod 302 from the guide groove 308, then expand the distance between the main frame 301 and the fixing rod 310, and then insert the hull between the fixing rod 310 and the main frame 301, and then close the main frame 301 and the fixing rod 310 together until the fixing rod 310 and the main frame 301 are in contact with the hull and then stop.

[0040] Then, the driving rods 302 on both sides of the mounting plate 101 are inserted into the guide grooves 308 on the main frame 301. When the driving rods 302 are inserted into the guide grooves 308, the driving teeth 303 on the driving rods 302 need to be aligned with the driven teeth 304 on the cross bar 305. Therefore, when the driving rods 302 are inserted into the guide grooves 308, the driving teeth 303 and the driven teeth 304 cooperate to push the cross bar 305 to move. Fig.11 and Fig.12 As shown, the maximum distance that the crossbar 305 moves is equal to the horizontal distance between the two ends of the driving teeth 303 arranged along the longitudinal length of the driving rod 302.

[0041] Moreover, the driving force of the driving tooth 303 comes from the gravity of the lifting assembly 1, the supporting assembly 2 and the engine, so it can prevent loosening. Fig.10 As shown, in order to further prevent the fixing rod 310 and the main frame 301 from loosening on the hull, the fixing bolt 309 on the limit frame 307 and the inclined surface of the anti-loosening groove 312 on the cross bar 305 can make the fixing rod 310 and the main frame 301 always have a tendency to move relative to each other, thereby ensuring the clamping effect.

[0042] After the fixing component 3 fixes the lifter on the ship, the telescopic device 103 can be used to change the angle between the connecting plate 102 and the mounting plate 101. The engine is installed on the connecting plate 102, and the mounting plate 101 is connected to the hull through the fixing component 3. Therefore, changing the angle between the mounting plate 101 and the connecting plate 102 also changes the angle of the propeller.

[0043] In the process of adjusting the angle between the mounting plate 101 and the connecting plate 102, since the support frame 201 is hinged to the mounting plate 101 and the slide bar 205 is hinged to the connecting plate 102, when the mounting plate 101 and the connecting plate 102 rotate relative to each other, the slide bar 205 will be pulled out from the support frame 201. Figure 4 and Figure 5As shown, during this process, the card block 206 will pass through the card slot 202 one by one. In the process of the card block 206 passing through the card slot 202, the telescopic column 2102 extending from the through hole 2105 on the fixed block 2101 will always keep in contact with the clamping groove 207 on the rotating block 211, pushing the card block 206 to quickly enter the groove valley of the adjacent card slot 202 after crossing the groove peak between the card slots 202.

[0044] like Figure 6 and Figure 7 As shown, when the slide bar 205 is pulled out to the maximum length, the block 206 will enter the fixed groove 204. Under the push of the side wall of the fixed groove 204, the block 206 will drive the rotating block 211 to rotate until the telescopic column 2102 is inserted into the positioning groove 208 on the rotating block 211 and then stops. At this time, the telescopic device 103 is shortened, and the block 206 will move along the slide groove 209 to the side of the release groove.

[0045] like Figure 8 As shown, when the clamping block 206 enters the release groove, it will drive the rotating block 211 to rotate in the opposite direction under the push of the side wall of the release groove, so that the telescopic column 2102 moves out of the positioning groove 208 and enters the clamping groove 207 again, and then the sliding rod 205 is pulled out again and repeats the process. Figures 4 to 8 process.

[0046] When the slide rod 205 is pulled, the card block 206 is inserted into different card slots 202 to achieve support at different angles between the connecting plate 102 and the mounting plate 101. Most of the force transmitted to the connecting plate 102 by the engine can be transmitted to the mounting plate 101 through the support component 2, and then transmitted to the hull through the fixing component 3 connected to the mounting plate 101, so that the propeller can push the ship to move at different angles.

[0047] The above is a detailed description of an embodiment of the present invention, but the content is only a preferred embodiment of the present invention and cannot be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent coverage of the present invention.
