Description

Technical Field

[0001] The invention belongs to the technical field of underwater machinery, and particularly relates to a device for carrying a vehicle on the side of a submersible, which is used for carrying large unmanned underwater vehicles on the side, etc. Background Technique

[0002] The existing carrying methods of submersibles mainly include side carrying method, piggyback carrying method, hull conformal docking method, launch tube carrying method, deck shelter cabin carrying method and bottom mounting method. Among them, the side carrying method is mainly used to carry larger vehicles on the side of large submersibles.

[0003] However, during the process of carrying a large unmanned underwater vehicle underwater, the navigation resistance is large, and the wave force generated by the water flow will cause the vehicle to shake, which will cause a large acting force on the connecting components between the vehicle and the submersible. Second, a large unmanned underwater vehicle will be subject to large navigation resistance and fluctuating disturbing forces underwater, which requires the carrying device to have a sufficiently large gripping force to ensure the safety and reliability of the carrying state. In addition, the space size on the side of the submersible is relatively compact, which greatly limits the size of the carrying device and makes it unable to fully function. Summary of the Invention

[0004] The purpose of the invention is to provide a device for carrying a large vehicle on the side of a submersible in view of the deficiencies of the prior art, aiming to solve the problem that the insufficient space on the side of the submersible in the prior art limits the size of the carrying device.

[0005] The technical solution adopted by the invention is: a device for carrying a vehicle on the side of a submersible, including a connection component and a locking component; the connection component includes a spiral swing hydraulic cylinder, a crank connecting rod mechanism, a torsion spring transmission rod and a pile leg; the spiral swing hydraulic cylinder is fixed on the side of the submersible, the output shaft of the spiral swing hydraulic cylinder is connected to the input end of the crank connecting rod mechanism, the output end of the crank connecting rod mechanism is connected to the middle part of the torsion spring transmission rod, the torsion spring transmission rod is connected to the pile leg, and the pile leg is adapted to the connection slot box arranged on the vehicle; the locking component includes a supporting bottom plate fixed on the side of the submersible and a manual locking rod; an installation groove is opened in the supporting bottom plate, the head of the manual locking rod is arranged in the installation groove, and the head of the manual locking rod is adapted to the locking slot box arranged on the vehicle.

[0006] According to the above scheme, the crank connecting rod mechanism includes a crank, a connecting rod and a swing rod connected in sequence; the input end of the crank is connected to the output shaft of the spiral swing hydraulic cylinder, and the output end of the swing rod is connected to the middle part of the torsion spring transmission rod; the output shaft of the spiral swing hydraulic cylinder drives the crank to rotate, the crank then drives the swing rod to rotate through the connecting rod, and the torsion spring transmission rod connected to the swing rod drives the pile leg to rotate, and is connected or separated from the corresponding connection slot box.

[0007] According to the above solution, the device is further provided with a bracket, and the bracket is fixed to the side of the submersible; the middle part of the torsion spring transmission rod is connected to the bracket, which is used to support the torsion spring transmission rod and allow the torsion spring transmission rod to rotate in the bracket.

[0008] According to the above solution, the device is further provided with a support pile, and the support pile is fixed to the side of the submersible.

[0009] According to the above solution, a flexible cushion layer is arranged on the outer end surfaces of the bracket, the support bottom plate and the support pile.

[0010] According to the above solution, the connecting slot box is a V-shaped slot box.

[0011] According to the above solution, the locking slot box is a strip-shaped slot box adapted to the head of the manual locking rod.

[0012] According to the above solution, the torsion spring transmission rod is made of stainless steel material.

[0013] The present invention also discloses a method for mounting a vehicle on the side of a submersible based on the above-mentioned vehicle mounting device on the side of the submersible. When the vehicle approaches and fits with the support bottom plate and the support pile in a lateral manner, the vehicle is in the mounting position; two groups of spiral swing hydraulic cylinders synchronously drive the corresponding crank-link mechanisms, and the crank-link mechanisms respectively drive the torsion spring transmission rods at the top and bottom. When the torsion spring transmission rods rotate, they drive the corresponding pile legs to rotate. When the pile legs rotate and close, they are inserted into the corresponding connecting slot boxes on the vehicle and pressed tightly; the head of the manual locking rod of the locking assembly extends from the support bottom plate, is inserted into each corresponding locking slot box of the vehicle and rotated 90° to lock and fix, so that the vehicle and the submersible are fixed under the action of the pile legs and the manual locking rod, realizing the mounting of the vehicle.

[0014] The present invention also discloses a method for releasing a vehicle based on the above-mentioned vehicle mounting device on the side of a submersible. After the manual locking rod of the locking assembly rotates 90° in the reverse direction and is pulled back, the head of the manual locking rod disengages from the locking slot box of the vehicle and returns to the corresponding support bottom plate; the spiral swing hydraulic cylinders synchronously drive the crank-link mechanisms in the reverse direction, so that the pile legs swing out of the corresponding connecting slot boxes, and the vehicle is released.

[0015] The beneficial effects of the present invention are as follows:

[0016] 1. The present invention adopts spiral swing hydraulic cylinders that are small in volume but can output powerful driving forces, driving two sets of crank-link mechanisms. The overall structure is compact and delicate. In the extremely limited space on the side of the submersible, it can still operate efficiently, greatly improving the space utilization efficiency, effectively overcoming the problem that traditional mounting devices cannot fully function due to limited space, and providing an efficient solution for equipment mounting in narrow spaces.

[0017] 2. The present invention adopts a torsion spring drive rod. With its elastic design, the torsion spring drive rod ensures that the pile leg is firmly pressed against the connection slot box in the mounted state. At the same time, when the pile leg rotates and closes, it can accurately fit into the connection slot box outside the vehicle. Combined with manual operation, insert the head of the manual locking rod into the locking slot box and rotate it by 90 degrees. Through the coordinated action of multiple components, the vehicle is firmly fixed on the support component. This design can effectively resist the strong navigation resistance and fluctuating disturbing forces encountered by the large unmanned underwater vehicle underwater, and comprehensively ensure the stability and safety of the mounted state.

[0018] 3. The pile leg in the present invention can rotate completely and retract into the side of the hull. At this time, the crank connecting rod mechanism is automatically locked, fully demonstrating the flexibility of the device's retraction and deployment. In addition, a coupling design is carried out for the elasticity of the torsion spring drive rod, the manual locking operation, and the locking function of the crank connecting rod mechanism to ensure that the device can maintain stable and reliable performance in both the working state of carrying the vehicle and the non-working state of retracting and storing in the side of the hull, adapting to different working conditions.

[0019] 4. A flexible cushion layer is provided on the outer end face of the support component in the present invention, which can effectively avoid scratching or damaging the surface of the vehicle during the process of carrying the vehicle.

[0020] 5. The present invention can flexibly adjust its own size and the number of components according to the requirements of vehicles of different sizes, perfectly adapting to the outer shapes of various specifications of vehicles. Moreover, the device is conveniently and reliably stored on the side of the hull in daily use, is easy to operate and has reliable performance when in use, can fully adapt to complex underwater environments, improves the versatility and practicality of the device, and provides an efficient, reliable and flexible innovative solution for the side-mounted large vehicle of the submersible.

[0028] As Figures 1 to 3 A device for carrying a vehicle on the side of a submersible as shown is fixed on the side of the submersible; the device includes a connection assembly and a locking assembly; the connection assembly includes a spiral swing hydraulic cylinder 1, a crank connecting rod mechanism 2, a torsion spring transmission rod 3 and a leg 4; the spiral swing hydraulic cylinder 1 is fixed on the side of the submersible, the output shaft of the spiral swing hydraulic cylinder 1 is connected to the input end of the crank connecting rod mechanism 2, the output end of the crank connecting rod mechanism 2 is connected to the middle of the torsion spring transmission rod 3, the torsion spring transmission rod 3 is connected to the leg 4, and the leg 4 is adapted to the connecting slot box 5 provided on the vehicle 10; the locking assembly includes a support bottom plate 7 fixed on the side of the submersible and a manual locking rod 6; an installation groove is provided in the support bottom plate 7, the head of the manual locking rod 6 is arranged in the installation groove, and the head of the manual locking rod 6 is adapted to the locking slot box 11 provided on the vehicle 10.

[0029] In the present invention, there are two groups of the connection assemblies, which are symmetrically arranged up and down; the spiral swing hydraulic cylinder 1 of the connection assembly drives the torsion spring transmission rod 3 to rotate through the crank connecting rod mechanism 2, and the leg 4 connected to the torsion spring transmission rod 3 swings accordingly and inserts into the connecting slot box 5 on the vehicle 10 and presses tightly (the head of the leg 4 is adapted to the connecting slot box 5), realizing the connection between the submersible and the vehicle 10. Three groups of locking assemblies are configured; the head of the manual locking rod 6 is strip-shaped, and after extending out of the support bottom plate 7, it inserts into the corresponding locking slot box 11 on the vehicle 10, and rotating 90 degrees can realize the locking of the vehicle 10.

[0030] In the present invention, the connecting slot box 5 is a V-shaped slot box; the locking slot box 11 is a strip-shaped slot box adapted to the head of the manual locking rod 6. The connecting slot box 5 is designed as a V-shaped slot box, which is convenient for the leg 4 to be inserted in a fault-tolerant manner and is suitable for the underwater environment with poor visibility. The form in which the manual locking rod 6 cooperates with multiple legs 4 to hold the corresponding connecting slot box 5 greatly improves the carrying capacity.

[0031] In the present invention, the spiral swing hydraulic cylinder 1 is installed on the cylinder seat, and the cylinder seat is connected to the side of the submersible by bolts; the spiral swing hydraulic cylinder 1 can output a large force with a small volume, and the output shaft of the spiral swing hydraulic cylinder 1 is connected to the input end of the crank-link mechanism 2, and the output shaft of the spiral swing hydraulic cylinder 1 rotates to drive the crank-link mechanism 2 to swing.

[0032] Preferably, the crank-link mechanism 2 includes a crank 12, a connecting rod 13 and a swing rod 14 connected in sequence; the input end of the crank 12 is connected to the output shaft of the spiral swing hydraulic cylinder 1, and the output end of the swing rod 14 is connected to the middle of the torsion spring transmission rod 3; the output shaft of the spiral swing hydraulic cylinder 1 drives the crank 12 to rotate, and the crank 12 then drives the swing rod 14 to rotate through the connecting rod 13, and the torsion spring transmission rod 3 connected to the swing rod 14 drives the pile leg 4 to rotate, and is connected or separated from the corresponding connection slot box 5.

[0033] In the present invention, one torsion spring transmission rod 3 is configured with three pile legs 4; when the crank 12 is located at two extreme positions respectively, the corresponding pile legs 4 are respectively in the fully extended position state (detached from the connection slot box 5) and the fully retracted position state (connected to the connection slot box 5); and the two position states can be maintained. The fully extended position state of the pile leg 4 is convenient for the vehicle 10 to enter the loading position in a lateral manner, and the fully retracted position state of the pile leg 4 can be reliably placed between the sides of the submersible.

[0034] Preferably, the device is further provided with a bracket 9, and the bracket 9 is fixed to the side of the submersible; the bracket 9 is connected to the middle of the torsion spring transmission rod 3 for supporting the torsion spring transmission rod 3 and allowing the torsion spring transmission rod 3 to rotate in the bracket 9.

[0035] Preferably, the device is further provided with a support pile 8, and the support pile 8 is fixed on the side of the submersible, and the position of the outer end face of the support pile 8 is the extreme position of the vehicle 10; the support column 8 is used to define the extreme position of the vehicle 10 during loading.

[0036] In the present invention, the bracket 9, the support bottom plate 7 and the support pile 8 are all support components (as Figure 4 and Figure 5 shown), and are respectively installed on the side of the submersible by bolts. The positions of the outer end faces (that is, the end faces facing the vehicle 10) of the three are the loading positions of the vehicle 10. When the vehicle 10 runs until it contacts the outer end faces of all three, it can be loaded; the outer end faces of the bracket 9, the support bottom plate 7 and the support pile 8 are provided with flexible cushions (specifically, rubber cushions) to prevent the vehicle 10 from contacting the support components and damaging the outer surface of the vehicle 10. The elastic force of the torsion spring transmission rod 3 can ensure that the pile leg 4 presses the V-shaped connection slot box 5 in the loaded state, realizing the firmness and reliability of the loaded state; to ensure the seawater adaptability of the torsion spring transmission rod 3, the torsion spring transmission rod 3 is made of stainless steel material.

[0037] A method for mounting a vehicle based on the vehicle mounting device on the side of a submersible as described above. The method is as follows:

[0038] When the vehicle 10 approaches and fits against the support bottom plate 7 and the support pile 8 in a lateral manner, the vehicle 10 is in the mounting position. The two groups of spiral swing hydraulic cylinders 1 synchronously drive the corresponding crank-link mechanisms 2, and the crank-link mechanisms 2 respectively drive the torsion spring transmission rods 3 at the top and bottom. When the torsion spring transmission rods 3 rotate, they drive the corresponding pile legs 4 to rotate. When the pile legs 4 rotate and close, they insert into the corresponding connecting slot boxes 5 on the vehicle 10 and reach the limit position to be pressed tightly. The head of the manual locking rod 6 of the locking assembly extends from the support bottom plate 7, inserts into the corresponding locking slot box 11 of the vehicle 10 and rotates 90° to be locked and fixed, so that the vehicle 10 and the submersible are fixed under the action of the pile legs 4 and the manual locking rod 6. At this time, the side mounting of the vehicle 10 is achieved.

[0039] A method for releasing a vehicle based on the vehicle mounting device on the side of a submersible as described above. The method is as follows:

[0040] The manual locking rod 6 of the locking assembly rotates 90° in the reverse direction and is pulled back, and the head of the manual locking rod 6 disengages from the locking slot box 11 of the vehicle 10 and returns to the corresponding support bottom plate 7. The spiral swing hydraulic cylinders 1 synchronously drive the crank-link mechanisms 2 in the reverse direction, so that the pile legs 4 swing out from the corresponding connecting slot boxes 5, and the vehicle 10 is released.

[0041] In the present invention, when the pile legs 4 are in the fully extended state, the crank-link mechanism 2 is in the locked position, which is convenient for the vehicle 10 to enter. When the device is not in use, the pile legs 4 can rotate to be completely retracted inside the side of the submersible, and the crank-link mechanism 2 is locked to achieve reliable return.
