Description

Technical Field

[0001] This utility model relates to the field of shipbuilding technology, specifically to a ship's liftable track structure. Background Technology

[0002] To enable ships to travel on land, they are typically equipped with four tracked vehicles, two on each side. To facilitate rapid movement of the ship both in water and on land, the four tracked vehicles are designed to be raised and lowered. When the ship needs to travel on land, the tracked vehicles are raised, and vice versa.

[0003] Currently, the aforementioned liftable track structures on ships have limitations. Specifically, different types of ships have different structures on the ramps used to install the track structures on both sides, and the angles of the ramps are different. This results in different ships requiring specific track structures. Therefore, there is still a need for a liftable track structure that can be docked with different ships.

[0004] Therefore, this utility model provides a ship liftable track structure. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a ship liftable track structure to solve the problems mentioned in the background technology. This utility model has the advantage of being more convenient to install and dock with different types of ships.

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution: a ship's liftable track structure, including a track machine and a mounting plate. The track machine includes a frame. A positioning shaft is ball-jointed to one side of the mounting plate. A cantilever is rotatably connected to one end of the positioning shaft. One end of the cantilever is rotatably connected to one side of the frame. An adjustment structure with a locking function for the positioning shaft is also provided on one side of the mounting plate. A positioning seat is fixedly connected to the outer peripheral wall of the positioning shaft. One side of the positioning seat is hinged to one end of the cantilever via a telescopic drive rod.

[0007] Furthermore, a ball joint seat is provided on one side of the mounting plate and is ball joint connected to one end of the positioning shaft. The adjustment structure includes an adjustment bolt and a hemispherical cover. A guide sleeve sleeved outside the positioning shaft is oscillatingly connected to the middle part of the outer spherical wall of the hemispherical cover. The guide sleeve and the positioning shaft are rotatably and axially slidingly engaged. The number of adjustment bolts is at least three and they are arranged around the ball joint seat. The adjustment bolts are screwed to one side of the mounting plate. The open end of the hemispherical cover abuts against one side of the mounting plate and its outer spherical wall is opposite to one end of the adjustment bolt.

[0008] Furthermore, a limiting plate is fixedly connected to one side of the mounting plate, and a limiting thread sleeve is welded through the limiting plate and sleeved on the outside of the adjusting bolt. The adjusting bolt is parallel to the mounting plate, and a limiting ring located at the opening end is fixedly sleeved on the outer spherical wall of the hemispherical cover. The limiting ring is located between the adjusting bolt and the mounting plate.

[0009] Furthermore, the adjustment structure includes a locking thread sleeve, and a locking thread sleeve is sleeved on the positioning shaft, located outside the hemispherical cover and opposite to one end of the guide sleeve. The outer spherical wall of the hemispherical cover is fixedly connected with circumferentially evenly distributed limiting partitions, and the outer peripheral wall of the guide sleeve is threaded through and screwed with a locking bolt that cooperates with the outer peripheral wall of the positioning shaft.

[0010] Furthermore, a handle is fixedly connected to the outer peripheral wall of the locking screw sleeve.

[0011] Furthermore, a connecting plate is fixedly connected to one side of the frame near the center, and the top of the connecting plate is hinged to one end of the cantilever.

[0012] Furthermore, one side of the frame is fixedly connected to a stop shaft located on both sides of the connecting plate, and the two sides of the cantilever are rotatably connected by a shock-absorbing telescopic rod and the stop shaft, respectively.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. In this utility model, an installation plate is provided, and a positioning shaft is connected to one side of the installation plate by a ball joint, so that the positioning shaft can move in all directions. One end of the positioning shaft is connected to a track machine through a cantilever. When the positioning plate is fixedly installed on both sides of different ships, the cantilever can be adjusted to be in a vertical plane by swinging the positioning shaft. This setting enables the track structure to quickly dock with different ships, greatly improving the adaptability of the structure.

[0015] 2. In this utility model, by setting an adjusting screw distributed around the positioning shaft on one side of the mounting plate, and then fitting a semi-circular cover on the positioning shaft, the spherical top of the semi-circular cover is connected to the guide sleeve, and the guide sleeve is fitted on the positioning shaft and the two are in rotational and sliding cooperation. Thus, by turning the adjusting screw, the levelness of the positioning shaft and the parallelism of the positioning shafts on both sides of the ship can be quickly adjusted, which has the advantages of more convenient and faster adjustment.

[0020] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0021] Please see Figures 1 to 3 This utility model provides a technical solution: a ship-mounted liftable track structure, including a track machine 1 and a mounting plate 2. In use, the mounting plate 2 can be welded to the inclined surfaces on both sides of the ship. The track machine 1 includes a frame 11, with tracks arranged on the outer periphery of the frame 11. The track machine 1 is a commonly available single-track walking device with a built-in drive structure; its specific structure will not be described in detail in this application.

[0022] In this technical solution, a positioning shaft 3 is ball-jointed to one side of the mounting plate 2. Specifically, a ball-joint seat 21 is provided on one side of the mounting plate 2, which is ball-jointed to one end of the positioning shaft 3. The positioning shaft 3 can swing in all directions. One end of the positioning shaft 3 is rotatably connected to a cantilever 4. One end of the cantilever 4 is rotatably connected to one side of the frame 11. When the positioning shaft 3 is horizontally distributed and the positioning shafts 3 on both sides of the ship are in a parallel state, controlling the up-and-down swing of the cantilever 4 can control the corresponding tracked machine 1 to rise and fall.

[0023] Furthermore, a positioning seat 6 is fixedly connected to the outer peripheral wall of the positioning shaft 3. One side of the positioning seat 6 is hinged to one end of the cantilever 4 via a telescopic drive rod 7. The telescopic drive rod 7 can be a hydraulic cylinder structure, which can control the up and down swing of the cantilever 4 when it extends or retracts.

[0024] Among them, an adjustment structure 5 with a locking positioning shaft 3 function is also provided on one side of the mounting plate 2.

[0025] Specifically, the adjusting structure 5 includes adjusting bolts 51 and a hemispherical cover 52. A guide sleeve 521, fitted outside the positioning shaft 3, is oscillatingly connected to the middle of the outer spherical wall of the hemispherical cover 52. Specifically, a limiting shaft can be welded to the outer circumferential wall of the guide sleeve 521, and a limiting hole is opened in the middle of the outer spherical wall of the hemispherical cover 52. The two ends of the limiting shaft are rotatably connected to the inner wall of the limiting hole. The guide sleeve 521 and the positioning shaft 3 are in a rotatable and axial sliding fit. During manufacturing, the guide sleeve 521 and the positioning shaft 3 can be configured as a clearance fit structure, in which case the positioning shaft 3 can move axially relative to the guide sleeve 521 and also rotate relative to the guide sleeve 521. The number of adjusting bolts 51 is at least three, and they are arranged around the ball joint seat 21. The adjusting bolts 51 are screwed onto one side of the mounting plate 2. The opening end of the hemispherical cover 52 abuts against one side of the mounting plate 2, and its outer spherical wall is opposite to one end of the adjusting bolt 51. By rotating and pushing the hemispherical cover 52, the swing of the positioning shaft 3 can be adjusted. When controlling the rotation of each adjusting bolt 51, the hemispherical cover 52 can be locked, thereby locking the position of the adjusted positioning shaft 3.

[0026] In this embodiment, a limiting plate 22 is fixedly connected to one side of the mounting plate 2. A limiting thread sleeve 221 is welded through the limiting plate 22 and sleeved on the outside of the adjusting bolt 51. The adjusting bolt 51 is parallel to the mounting plate 2. A limiting ring 522 located at the opening end is fixedly sleeved on the outer spherical wall of the hemispherical cover 52. The limiting ring 522 is located between the adjusting bolt 51 and the mounting plate 2. The adjusting bolt 51 can limit the hemispherical cover 52 through the limiting ring 522, so that the opening end of the hemispherical cover 52 is in a state of being in contact with or approximately in contact with the mounting plate 2. This arrangement facilitates the omnidirectional movement of the hemispherical cover 52 along the side wall of the mounting plate 2.

[0027] In this embodiment, the adjusting structure 5 includes a locking sleeve 53. A locking sleeve 53 is fitted onto the positioning shaft 3, located outside the hemispherical cover 52 and opposite one end to the guide sleeve 521. When the locking sleeve 53 is tightened, it can compress the guide sleeve 521, thereby pushing the hemispherical cover 52 to compress the mounting plate 2. This arrangement can secure the hemispherical cover 52 and the positioning shaft 3, effectively preventing the hemispherical cover 52 and the positioning shaft 3 from shaking. The outer spherical wall of the hemispherical cover 52 is fixedly connected with circumferentially evenly distributed limiting partitions 523. When the adjusting bolt 51 is tightened, one end is located between two adjacent limiting partitions 523, effectively preventing the hemispherical cover 52 from twisting. The outer peripheral wall of the guide sleeve 521 is screwed with a locking bolt 8 that works in conjunction with the outer peripheral wall of the positioning shaft 3. When the locking bolt 8 is tightened, it can lock the guide sleeve 521 and the positioning shaft 3, preventing the positioning shaft 3 from rotating freely. In specific implementation, circumferentially evenly distributed limiting grooves can be opened on the outer peripheral wall of the positioning shaft 3. When the locking bolt 8 is tightened, one end of it will enter one of the limiting grooves, thereby increasing the reliability of the positioning shaft 3 being locked.

[0028] Furthermore, a lever 531 is fixedly connected to the outer peripheral wall of the locking sleeve 53, which is the operating component for manually tightening the locking sleeve 53 when the lever 531 is used.

[0029] In this embodiment, a connecting plate 111 is fixedly connected to one side of the frame 11 near the middle. The top of the connecting plate 111 is hinged to one end of the cantilever 4. The hinge connection between the cantilever 4 and the connecting plate 111 is higher than the height of the tracked machine 1. When the center of gravity of the tracked machine 1 is below this hinge connection, it is convenient for the tracked machine 1 to use its own weight to be in a parallel downward state.

[0030] Furthermore, a retaining shaft 112 located on both sides of the connecting plate 111 is fixedly connected to one side of the frame 11, and the two sides of the cantilever 4 are rotatably connected to the retaining shaft 112 via a shock-absorbing telescopic rod 9. The shock-absorbing telescopic rod 9 not only limits the angle between the tracked machine 1 and the cantilever 4, but also buffers the impact force generated by the swing of the tracked machine 1.

[0031] Working principle: During use, external auxiliary equipment is used to support the tracked machine 1. Then, the mounting plate 2 is welded to the positions on both sides of the ship. After the mounting plate 2 is fixed, the hemispherical cover 52 is rotated and pushed. Then, the level of the positioning shaft 3 is adjusted using a level instrument, and the parallelism of the positioning shaft 3 on both sides of the ship is adjusted using a laser rangefinder (a horizontal reference plate is placed on the front of the ship, perpendicular to the hull, and the laser rangefinder is slidably set on the reference plate to measure the distance between the positioning shaft 3 on both sides of the ship and the reference plate). After adjustment, each adjusting bolt 51 is tightened so that one end of the adjusting bolt 51 abuts against the outer spherical wall of the hemispherical cover 52. Then, the locking thread sleeve 53 is tightened, and finally the locking bolt 8 is tightened. At this time, the position of the positioning shaft 3 is fixed. At this time, controlling the extension and retraction of the telescopic drive rod 7 can control the cantilever 4 to swing up and down, thereby driving the corresponding tracked machine 1 to rise and fall.

[0032] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
