[0028] In order to make the purpose, technical solutions and advantages of the embodiments of the present disclosure more clear, the technical solutions of the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings of the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, not all of the embodiments. Based on the described embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.

[0029] like Figure 1-8As shown, a ship lift counterweight hoisting device includes a pulley 1, a rope 11 sleeved on the pulley 1 and a first fixed plate 13, and also includes a swing support mechanism 2. The swing support mechanism 2 includes a rotating ball 22 movably set on the first fixed plate 13, and a support block 21 is set on the rotating ball 22. The support block 21 is driven to fit the rope 11 and flips as the rope 11 swings.

[0030] Specifically, a rope 11 is sleeved on the pulley 1, and the pulley 1 is rotatably connected to the first fixed plate 13. The two ends of the rope 11 are respectively connected to the ship-bearing box and the counterweight 12, and also include a swing support mechanism 2, which includes a rotating ball 22 movably arranged on the first fixed plate 13, and a supporting block 21 is provided on the rotating ball 22. The supporting block 21 is provided with a groove that fits the size of the rope 11. The swing support mechanism 2 also includes a connecting plate 241 fixedly connected to the first fixed plate 13, and a fixed frame 24 is fixedly connected to the connecting plate 241. A rotating sleeve 23 is slidably connected in the fixed frame 24, and a first spring 242 is fixedly connected between the two. The first spring 242 can always push the rotating sleeve 23 to slide out of the fixed frame 24. A sliding plate 232 for guiding is provided on the rotating sleeve 23, and the rotating ball 22 is rotatably connected in the rotating sleeve 23; when the ship-bearing box moves along with the pulley When the pulley 1 is turned upside down or down, the water in the boat box will slide with the movement of the boat box. At this time, the boat box drives the rope 11 to swing with the pulley 1 as the base point, and the rotating sleeve 23 will slide along the fixed frame 24 to make the supporting block 21 fit the rope 11 so that the rope 11 between the pulley 1 and the boat box has an additional position with the supporting block 21 as the base point, so that the swing range of the rope 11 when swinging is divided into two sections. The first section swings between the supporting block 21 and the boat box, and the second section swings between the supporting block 21 and the pulley 1 to reduce the swing between the rope 11 and the pulley 1 and thus reduce friction, so as to protect the rope 11 and reduce the possibility of breakage, and extend the life of the rope 11, and the supporting block 21 can also make the rotating ball 22 rotate along the rotating sleeve 23 as the rope 11 swings, so as to prevent the rope 11 from swinging too much and the supporting block 21 from detaching.

[0031] In the above technical solution, when the ship-carrying box drives the rope 11 to swing with the pulley 1 as the base point, the support block 21 will always fit the rope 11 so that the rope 11 between the pulley 1 and the ship-carrying box has an additional support block 21 base point, so as to reduce the swinging between the rope 11 and the pulley 1 and thus reduce friction, so as to protect the rope 11 and reduce the possibility of breakage, extend the life of the rope 11, and the support block 21 can also flip as the rope 11 swings to avoid excessive swinging of the rope 11 and the detachment of the support block 21.

[0032] As a further embodiment provided by the present invention, it also includes a counterweight 12 slidably connected to the first fixed plate 13, and a swing counterweight mechanism 3 is provided on the counterweight 12. The swing counterweight mechanism 3 includes several resistance rotating plates 32 rotatably connected to the first fixed plate 13, and a second spring 322 is fixedly connected between the resistance rotating plate 32 and the first fixed plate 13. A rotating column 321 is provided on the first fixed plate 13, and the resistance rotating plate 32 is rotatably connected to the resistance rotating plate 32. The second spring 322 is used to keep the resistance rotating plate 32 in a horizontal position; when the swing counterweight mechanism 3 is needed, the resistance rotating plate 32 is driven to fit the counterweight 12. At this time, the counterweight 12 needs to break away from the fitted resistance rotating plate 32 when it is displaced, so that the weight of the counterweight 12 that needs to be moved becomes larger, so that the ship box will not pull the counterweight 12 to shake together when it shakes, and when the counterweight 12 slides normally along the first fixed plate 13, the counterweight 12 will break away from the resistance of the resistance rotating plate 32 to drive the resistance rotating plate 32 to flip.

[0033] As an embodiment further provided by the present invention, a second fixed plate 30 is provided on the counterweight 12, and sliding plates 301 corresponding to the resistance rotating plates 32 are slidably connected in a linear array inside the second fixed plate 30; when the ship box shakes, the sliding plate 301 is driven to extend out of the second fixed plate 30 to fit the resistance rotating plate 32 corresponding to the sliding plate 301, so that the resistance rotating plate 32 and the counterweight 12 fit together.

[0034] As another embodiment further provided by the present invention, a curved pipe 302 is provided on the second fixed plate 30, and a first end of the sliding plate 301 (with Figure 8 The first end is the right end and the second end is the left end) is located in the curved pipe 302, and a mortgage elastic tube 311 is provided in the curved pipe 302. The first end of the sliding plate 301 is provided with a rounded corner, which can reduce the force required for the mortgage elastic tube 311 to push against the sliding plate 301; when the sliding plate 301 needs to be extended, the mortgage elastic tube 311 is driven to slide along the curved pipe 302 to drive the sliding plate 301 to be squeezed out of the curved pipe 302, so that the sliding plate 301 is fitted with the resistance rotating plate 32.

[0035] As another embodiment further provided by the present invention, a vertical slider 313 is slidably connected to the second fixed plate 30, and the mortgage elastic tube 311 is wrapped around the vertical slider 313. A third fixed plate 312 is provided on the second fixed plate 30, and the vertical slider 313 is slidably connected to the third fixed plate 312. The curved pipe 302 includes a pipe inlet, and a fixed column is provided at the pipe inlet. An elastic belt is sleeved between the fixed column and the vertical slider 313; when the mortgage elastic tube 311 is driven to slide along the curved pipe 302, the mortgage elastic tube 311 wrapped around the vertical slider 313 will be reduced, so that the vertical slider 313 is pulled close to the curved pipe 302 by the elastic belt, so that the mortgage elastic tube 311 is in a horizontal state when entering the pipe inlet of the curved pipe 302, so as to maintain the smooth entry of the mortgage elastic tube 311.

[0036] As the best embodiment provided by the present invention, the mortgage elastic tube 311 includes a fixed central tube 3111, on which a spacer ring is arranged in a linear array. Figure 7The first end is the right end) and an extrusion head 3112 is provided. A motor 33 is provided on the second fixed plate 30. The output end of the motor 33 is provided with a dial plate 331 in a circumferential array. The dial plate 331 is embedded between the two spacer rings. The inner wall of the rotating sleeve 23 is provided with a multi-layer stacked contact ring 231. The rotating ball 22 is provided with a guide ring 221. The guide ring 221 and the contact ring 231 are electrically connected to the motor 33. When the ship box rises or falls with the flip of the pulley 1, the water in the ship box will move with the ship box. At this time, the ship box drives the rope 11 to swing with the pulley 1 as the base point, and the rotating sleeve 23 slides along the fixed frame 24 to make the supporting block 21 fit the rope 11 so that the rope 11 between the pulley 1 and the ship box has an additional position with the supporting block 21 as the base point, so that the rope 11 swings in sections, the first section swings between the supporting block 21 and the ship box, and the second section swings between the supporting block 21 and the pulley 1 to reduce the swing between the rope 11 and the pulley 1, thereby reducing friction. The rope 11 is protected to reduce the possibility of breakage and extend the service life of the rope 11. The support block 21 can also make the rotating ball 22 rotate along the rotating sleeve 23 as the rope 11 swings, so as to prevent the rope 11 from swinging too much and the support block 21 from detaching. When the rotating ball 22 rotates along the rotating sleeve 23, the guide ring 221 on the rotating ball 22 will contact different contact rings 231 according to the swing amplitude of the rope 11 (the greater the swing, the outer the guide ring 221 is in contact with). At this time, the guide ring 221 and the corresponding contact ring 231 are electrically connected, so that the output end of the motor 33 rotates a certain number of circles, so that the dial plate 331 flips and pushes the mortgage elastic tube 311 to slide along the curved pipe 302, thereby pushing the sliding plate 301 out of the second fixed plate 30 and fitting it with the resistance rotating plate 32. The greater the swing, the more sliding plates 301 fit with the resistance rotating plate 32, and the greater the force required to drive the counterweight 12. The greater the force, the slower and offsets the swing of the ship box to make the rising and falling process smooth.

[0037] The above description is merely illustrative of certain exemplary embodiments of the present invention. It goes without saying that those skilled in the art will be able to modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims.
