Description

Technical Field

[0001] The invention relates to the field of ship traction devices, in particular to a ship traction mechanism. Background Art

[0002] When a ship needs to be towed onto the slipway for repair or maintenance, it is usually necessary to use an upper row mechanism to move the ship to the corresponding position of the slipway. When the repair or maintenance is completed, it is necessary to use a launching mechanism to move the ship into the water. In the prior art, in the method of towing the ship onto and launching into the water by track, the contact surface between the ship's bottom and the flat steel plate is usually a flat steel plate. The friction between the bottom of the ship and the flat steel plate allows the ship to be towed ashore or launched with the ship's row vehicle. This structure completely relies on the gravity of the ship to generate friction with the ship's row vehicle. If the gravity of the ship is insufficient, it is easy to slip during the towing process.

[0003] In the prior art, for some small ships, a structure in which a track, a winch and a steel cable cooperate is often used to pull the ship along the track and into the water. However, in this process, a traction mechanism such as a winch cannot slow down the speed of the ship because the track is generally set in an inclined state. As the steel cable is pulled, the ship will be affected by its own gravity and inertia when sliding downward and quickly descend into the water. In this process, the anchor piles used to fix the track or the connecting ends of the steel cables may be damaged by the inertial pulling force of the ship. Summary of the invention

[0004] In view of the shortcomings of the prior art, the purpose of the present invention is to provide a ship traction mechanism to solve the problems raised in the above-mentioned background technology.

The device is fixed on the slope in front of the water surface through the mounting plate 13 and the fixed pile 2, and then the buffer rope 54 installation path passes through the front seat 52, the axle rod 43 and the fixed pile 2, and the boat is placed on the front seat 52 and the driving seat 51, and then the boat is driven to move along the track by the driving component 3 and slowly sent into the water. In this process, the buffer component 4 is used to reduce the impact force caused by the inertia of the boat.

[0029] In this embodiment, the top of the bottom plate 1 is slidably connected with a moving plate 14, and the first screw 16 is rotatably installed on the upper end of the moving plate 14 on the inner wall of the two groups of the first rails 11 through the bearing seat, and a motor 17 is fixed to the position of the bottom plate 1 corresponding to one end of the first screw 16, and the output end of the motor 17 is fixedly connected to the first screw 16, and the tail end of the moving plate 14 is meshed and sleeved on the surface of the first screw 16, and plug plates 15 are fixedly installed on both sides of the moving plate 14 at equal distances, and the inner wall of the second rail 12 corresponds to the plug plates 1 5, and the plug plate 15 can be slidably inserted into the slot 19. When the second track 12 is flipped open, the motor 17 is turned on to drive the first screw 16 to rotate, and the movable plate 14 is meshed with the first screw 16 to slide out along the top of the bottom plate 1. When the second track 12 is completely aligned with the first track 11, the plug plates 15 on both sides of the movable plate 14 are inserted into the slot 19 to limit the second track 12. When not in use, the second track 12 and the movable plate 14 are stored, thereby facilitating the transportation and use of the device.

[0030] In this embodiment, the driving assembly 3 includes a toothed plate 32, a toothed plate 32 is fixed on the outer side of the driving seat 51, and the bottom of the toothed plate 32 is meshedly connected with the gear 31, a fixing plate 45 is fixed on the position of the sliding frame 41 corresponding to the gear 31, and the gear 31 is rotatably mounted on the fixing plate 45 through a bearing, and the buffer assembly 4 also includes a slider 42, a slider 42 is slidably connected to the position of the shaft rod 43 inside the sliding frame 41, and the slider 42 is fixed to the bottom of the shaft rod 43, a spring 44 is fixed between the slider 42 and the inner wall of the other side of the sliding frame 41, and the front and rear ends of the sliding frame 41 are both installed with fixing plates 45, and the fixing plate 45 is rotatably mounted with a second screw 47 at the position corresponding to the gear 31 through a bearing, and the second screw 47 The second screw 47 and the sliding rod 48 are both mounted with connecting blocks 410, and the connecting blocks 410 are respectively slidably and meshingly sleeved with the sliding rod 48 and the second screw 47. A buffer telescopic rod 46 is fixed to the top of the connecting block 410, and an arc belt 49 is fixed to the extended end of the buffer telescopic rod 46. The arc belt 49 is in compression contact with the surface of the shaft rod 43. The technical principle of the buffer telescopic rod 46 can be that a buffer spring 44 is arranged inside the telescopic rod, so that in a stationary state, there is a certain interval between the connecting block 410 and the arc belt 49. The function of the interval is that when the driving seat 51 moves, the tooth plate 32 translates and meshes with the gear 31. (The tooth plate 32 The translation method can be achieved by an external driving device, such as a cylinder and a push rod, to push the driving seat 51 to move along the first track 11 and the second track 12). Then the gear 31 drives the second screw 47 to rotate, and the two sets of connecting blocks 410 move along the surface of the second screw 47 and the sliding rod 48 respectively. In the initial stage, the arc belt 49 contacts the shaft 43, and when the connecting block 410 moves, the ship drives the buffer rope 54 to move, and the shaft 43 slides along the sliding frame 41 synchronously. At this time, the shaft 43 is subjected to the elastic force of the bottom spring 44 to reduce the inertial impact force of the ship. On the other hand, when the inertia of the ship is large, the movement speed of the shaft 43 will exceed the connecting block 410. At this time, the buffer telescopic rod 46 on the top of the connecting block 410 can further slow down the movement of the shaft 43. Speed, thereby reducing the impact force caused by the inertia of the ship. The sliding frame 41 is partially installed on the outside of the bottom plate 1 through hinge rotation. When not in use, it can be folded and stored like the second track 12, which is convenient for storing and carrying the device (the arc belt 49 is a rubber belt with a certain degree of softness and elasticity. Compared with materials with higher hardness, it can reduce the wear when it contacts and squeezes the shaft rod 43, but the arc belt 49 is not very soft and the thickness of the arc belt 49 is relatively thick. The extended end of the buffer telescopic rod 46 is fixedly connected to the outer side of the arc belt 49 by bolts, which is detachable. Because of its thickness, the arc belt 49 itself can be used many times. Even if it breaks, it can be replaced with a new rubber arc belt 49 after being separated from the extended end of the buffer telescopic rod 46 by unlocking the bolts and continuing to use.Moreover, the arc band 49 can be disassembled and replaced according to the usage. Therefore, under the premise that a new arc band 49 can be replaced at any time, the arc band 49 only needs to meet the maximum impact force that the arc band 49 can withstand. In addition, the device also has a spring inside the buffer telescopic rod 46 to cooperate with and offset the impact force, which is not entirely borne by the arc band 49. The arc band 49 is mainly used to connect the shaft 43 and the buffer telescopic rod 46).

[0031] In this embodiment, the bearing assembly 5 also includes a curved surface 53. The inner surfaces of the driving seat 51 and the front seat 52 are both provided with curved surfaces 53 that match the curvature of both sides of the ship. A guide cylinder 18 is fixed on the outer wall of the first track 11 at a position corresponding to the passage of the buffer rope 54, and the buffer rope 54 passes through the guide cylinder 18. Two fixing rings 21 are fixed on the surface of the fixed pile 2, and one end of the buffer rope 54 is fixedly connected to the fixing ring 21. The buffer rope 54 bypasses the front seat 52 and the shaft rod 43 and is fixed on the fixing ring 21 of the fixed pile 2. The bent part bypassing the shaft rod 43 is used as a spare length to facilitate sending the ship into the water. At the same time, both ends of the buffer rope 54 are connected to the two fixed piles 2, and one end can be directly disassembled. The disassembly and installation method is the common bolt fixing installation, which is not shown in the figure. Through the guiding effect of the guide cylinder 18, the position of the buffer rope 54 is kept in the same straight line with the fixing ring 21 of the fixed pile 2. The curved surface 53 on the inner surface of the front seat 52 and the driving seat 51 can better contact with both sides of the bottom of the ship, thereby sending the ship into the water.

[0032] When the device is in use, when the second track 12 is flipped open, the motor 17 is turned on to drive the first screw 16 to rotate, and the movable plate 14 is meshed with the first screw 16 and slides out along the top of the bottom plate 1. When the second track 12 is completely in the same straight line with the first track 11, the plug plates 15 on both sides of the movable plate 14 are inserted into the slots 19 to limit the second track 12. When not in use, the second track 12 and the movable plate 14 are stored, and then the drive seat 51 and the front seat 52 are installed. The device is fixed on the slope in front of the water surface through the mounting plate 13 and the fixed pile 2, and then the buffer rope 54 is installed through the front seat 52, the shaft 43 and the fixed pile 2, and the boat is placed on the front seat 52 and the drive seat 51. Then, the boat is driven to move along the track through the driving component 3 and slowly sent into the water. In a stationary state, the boat is connected There is a certain gap between the connecting block 410 and the arc belt 49. The function of the gap is that when the driving seat 51 moves, the tooth plate 32 translates and engages with the gear 31, and then the gear 31 drives the second screw 47 to rotate, and the two groups of connecting blocks 410 move along the surface of the second screw 47 and the sliding rod 48 respectively. In the initial stage, the arc belt 49 contacts the shaft rod 43, and when the connecting block 410 moves, the ship drives the buffer rope 54 to move, and the shaft rod 43 slides along the sliding frame 41 synchronously. At this time, the shaft rod 43 is subjected to the elastic force of the bottom spring 44 to reduce the inertial impact force of the ship. On the other hand, when the inertia of the ship is large, the moving speed of the shaft rod 43 will exceed the connecting block 410. At this time, the buffer telescopic rod 46 on the top of the connecting block 410 can further slow down the moving speed of the shaft rod 43, thereby reducing the impact force caused by the inertia of the ship.
