Description

Technical Field

[0001] This utility model relates to the field of circulating lifting equipment technology, and in particular to a return ship vertical circulating lifting system. Background Technology

[0002] Water ski boats, such as inflatable rubber boats, need to be transported from the end of the river or water slide back to the starting point for easy reuse. For locations with significant elevation differences, vertical lifting of the water ski boats is required, necessitating the following solutions: On the lifting side, the water ski boat must be easily hoisted while ensuring hoisting stability to prevent issues such as the boat detaching midway; when transporting the water ski boat to the detachment point on the lowering side, the detachment must be easy to complete to improve the efficiency of the return trip. Utility Model Content

[0003] This invention proposes a vertical circulation lifting system for returning a ship, which enables vertical lifting of the ship's hull, ensuring the stability of the hull during transportation and preventing it from falling off midway; moreover, it facilitates the hull's detachment at the detachment point, improving the efficiency of returning the ship.

[0004] The technical solution of this utility model is implemented as follows: A vertical circulation lifting system for returning ships includes a vertical frame. Both ends of the vertical frame are provided with motor-driven annular conveyor chains along the vertical direction. A hull support assembly is provided between the two annular conveyor chains. The hull support assembly includes a support frame and a hanging frame. The ends of the support frame and the hanging frame are connected to the annular conveyor chains. On the lifting side of the annular conveyor chains, the hanging frame is located above the support frame. The hanging frame is used to hang the upper side of the hull, and the support frame is used to support the lower side of the hull.

[0005] Furthermore, the hanging frame includes a first crossbar, the end of which is connected to an annular conveyor chain. Both ends of the first crossbar are fixed with arc-shaped support rods along the longitudinal direction, and a transverse hanging rod is fixed between the free ends of the two arc-shaped support rods.

[0006] Furthermore, the support frame includes a second crossbar, the end of which is connected to an annular conveyor chain; both ends of the second crossbar are fixed with longitudinal support rods, the free ends of the longitudinal support rods are fixed with vertical rings, and a transverse top rod is fixed between the free ends of the two longitudinal support rods.

[0007] Furthermore, support sprockets are provided at intervals along the vertical direction on both sides of the end of the vertical frame, and chain pressure plates that cooperate with the support sprockets are also fixed on the vertical frame. The annular conveyor chain passes between the support sprockets and the chain pressure plates to limit the conveying path of the annular conveyor chain.

[0008] Furthermore, the vertical frame is equipped with pivots on both the top and bottom sides, and each pivot has a corner sprocket at its end. The annular conveyor chain is fitted onto the corner sprocket at the same end.

[0009] Furthermore, the motor is a geared motor, which is fixed to the top of the vertical frame and connected to a rotating shaft at the top via a sprocket and chain.

[0010] The beneficial effects of this utility model are:

[0011] This invention utilizes a ring-shaped conveyor chain to drive a hull support assembly for lifting the hull. The hull support assembly includes a support frame and a hanging frame. On the lifting side, the hanging frame is on top to hold the upper part of the hull, while the support frame supports the lower part of the hull, facilitating rapid hoisting of the hull and ensuring the stability of the hull transport and hoisting to prevent it from falling off midway. On the lowering side, the support frame is on top and the hanging frame is below, facilitating the hull detachment, improving the efficiency of returning the hull, and achieving safe and rapid transport of the hull.

[0012] The sidewalls of the water skier are curved due to inflation, and the junction between the sidewalls and the bottom has a concave structure. On the lifting side, curved support rods fit against the inner sidewall of the upper part of the hull, thus placing the transverse hanger at the junction of the inner sidewall and the bottom, ensuring the stability of the hoisting and facilitating rapid hoisting of the hull. The support frame supports the lower part of the hull, preventing the hull from swaying and falling off during the lifting process. On the lowering side, the hoisting frame is below and the support frame is above. The hull slides down due to gravity, and the upward-facing sidewall of the hull abuts against the vertical ring of the support frame. The transverse hanger disengages from the junction of the inner sidewall and the bottom of the hull, allowing the hull to detach from the hull support components under gravity and land on the platform at the detachment point.

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] In this utility model, the terms "horizontal" and "vertical" are relative to... Figure 1 The positional relationship is shown.

[0025] like Figure 1 , 2 As shown in Figures 4, 5, and 8, a vertical circulation lifting system for returning ships includes a vertical frame 1. Support sprockets 2 are spaced vertically at both ends of the vertical frame 1, and the support sprockets 2 are rotatably connected to the vertical frame 1 via bearing seats. Rotating shafts 3 are rotatably connected to the top and bottom sides of the vertical frame 1 via bearing seats. Angle sprockets 4 are fixed to the ends of the rotating shafts 3. Annular conveyor chains 5 are arranged vertically at both ends of the vertical frame 1, and the annular conveyor chains 5 are fitted onto the angle sprockets 4 and support sprockets 2 at the same end.

[0026] A motor 6 is fixed to the top of the vertical frame 1. The motor 6 is a geared motor. The motor 6 is connected to a rotating shaft 3 at the top through a sprocket and chain. The motor 6 drives the corner sprocket 4 to rotate. The corner sprocket 4 drives the annular conveyor chain 5. The support sprocket 2 is used to support the annular conveyor chain 5. A chain pressure plate 7 that cooperates with the support sprocket 2 is also fixed on the vertical frame 1. The annular conveyor chain 5 passes between the support sprocket 2 and the chain pressure plate 7 to limit the conveying path of the annular conveyor chain 5 and prevent the annular conveyor chain 5 from detaching from the support sprocket 2.

[0027] like Figure 3 , 6As shown in Figure 7, a hull support assembly is provided between the two annular conveyor chains 5 at intervals. The hull support assembly includes a support frame 8 and a hanging frame 9. The ends of the support frame 8 and the hanging frame 9 are connected to the annular conveyor chains 5. On the lifting side of the annular conveyor chains 5, the hanging frame 9 is located above the support frame 8 and is used to hang the upper side inside the hull 16. The support frame 8 is used to support the lower side inside the hull 16. On the lowering side, the support frame 8 is located above the hanging frame 9.

[0028] The suspension frame 9 includes a first crossbar 10, the end of which is fixedly connected to the annular conveyor chain 5. Both ends of the first crossbar 10 are longitudinally fixed with arc-shaped support rods 11. On the lifting side, the arc-shaped support rods 11 are inclined upwards, and a transverse hanging rod 12 is fixed between the free ends of the two arc-shaped support rods 11. The arc-shaped support rods 11 facilitate matching with the inner side of the upper end of the hull 16, and allow the transverse hanging rod 12 to be placed at the junction of the side wall and bottom of the hull 16, thus making the support more stable.

[0029] The support frame 8 includes a second crossbar 13, the end of which is fixedly connected to the annular conveyor chain 5; both ends of the second crossbar 13 are longitudinal support rods 14, and a transverse top rod 15 is fixed between the free ends of the two longitudinal support rods 14. A vertical ring 17 is fixed to the free end of the longitudinal support rod, and the arc surface of the vertical ring 17 forms a sliding surface.

[0030] The cooperation between the suspending frame 9 and the support frame 8 prevents the hull 16 from falling off during its ascent. When the hull 16 is transported to the descent side, the support frame 8 faces upward and the suspending frame 9 faces downward. Due to gravity, the horizontal hanging rod 12 of the suspending frame 9 disengages from the junction of the side wall and bottom of the hull 16. Meanwhile, due to the vertical ring 17 of the support frame 8, the vertical ring 17 abuts against the upward-facing side wall of the hull 16. The horizontal top rod 15 can only abut against the bottom of the hull 16 and cannot be placed at the junction of the side wall and bottom of the hull 16, thus facilitating the detachment of the hull 16.

[0031] The method of using the vertical circulation lifting system for returning the ship is as follows: At the bottom of the lifting side of the annular conveyor chain 5, the worker hangs the hull 16 horizontally on the hull support assembly. The hanging frame 9 is used to hang the upper side inside the hull 16. Specifically, the arc-shaped support rod 11 abuts against the inner side wall of the upper end of the hull 16, and the horizontal hanging rod 12 is placed at the junction of the side wall of the upper end of the hull 16 and the bottom. The support frame 8 is used to support the lower side inside the hull 16, and the horizontal top rod 15 abuts against the bottom of the hull 16.

[0032] As the annular conveyor chain 5 is lifted, the hull 16 passes over the top via the lifting side and then enters the descending side of the annular conveyor chain 5. The support frame 8 is on top and the hanging frame 9 is below. Due to gravity, the upward side wall of the hull 16 abuts against the vertical ring 17 of the support frame 8. The horizontal hanging rod 12 of the hanging frame 9 disengages from the junction of the side wall and the bottom of the hull 16, making it easier for the hull 16 to detach from the hull support assembly.

[0033] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
