Due to limitations in the size of offshore platform placement areas, limited energy resources, and the humid and swaying marine environment, conventional automated transportation methods are quite difficult to implement.

[0007] The upper guide rail has a J-shaped stop bar at the beginning and end of the upper guide rail respectively, and a J-shaped stop bar at the end of the upper guide rail. The lower guide rail has a J-shaped stop bar at the end of the lower guide rail, and a straight stop bar at the end of the transverse guide rail.

[0008] The device also includes a ball-retrieving device for transporting the buoys.

[0009] Furthermore, a top grille is provided above the upper guide rail, and the top grille is located on the top of the support frame.

[0010] Further, the side walls of the transverse guide rail and longitudinal guide rail are provided with limiting chains for limiting floating balls.

[0011] Further, the deceleration curtain is arranged near the tail end of the transverse guide rail and longitudinal guide rail.

[0020] S2. Storage of floating ball

[0021] The storage of floating ball is on the transverse guide rail and longitudinal guide rail, and all the baffle rods are closed during storage.

[0054] The working method of the offshore floating ball automatic force transfer device comprises the following steps:

[0055] S1. Hoist and store the floating ball

[0056] Place the floating ball in the hanging basket 9b, the hanging basket bottom plate 9c has an inclination of 5°, and the floating ball will freely roll into the inside of the hanging basket 9b; after lifting the ball collecting hoist 9 and the floating ball, the ball collecting hoist 9 approaches the floating ball inlet of the upper guide rail and cooperates with the hook at the bottom of the inlet, and as the crane continues to lift, the rear end of the hanging basket 9b is raised, the floating ball is placed into the upper guide rail, the floating ball freely rolls to other guide rails, and the process is repeated until all the floating balls are stored;

[0057] S2. Store the floating ball

[0058] The floating ball is stored on the transverse guide rail and the longitudinal guide rail, and all the baffles are closed during storage.

[0059] S3. Transport the floating ball

[0060] During transportation, first open the transverse tail straight baffle 5e at the tail end of the transverse guide rail 1f, because the guide rail structure is arranged with an inclination of 5°, and the rollers 1c are arranged on the roller inclined plates 1a, the floating ball freely rolls down, the floating ball in the transverse guide rail 1f is transported, then the lower tail J-shaped baffle 5c is opened, the floating ball in the lower guide rail is transported first, then the floating ball in the upper guide rail is transported, and the process is repeated until all the floating balls are transported.

[0061] S4. Intermittent transfer mechanism transfers the floating ball

[0062] The initial state of the longitudinal intermittent transfer mechanism 61 at the tail end of the upper rail, the heavy end 6c freely falls and contacts the inner surface of the rail bottom plate 1b, reaching the lower limit position; at this time, the upper surface of the heavy end 6c is kept horizontal with the height of the roller chute, and the floating ball freely rolls over the heavy end 6c and the transfer shaft 6b. When the floating ball moves to the light end 6d, the weight of the floating ball and the light end 6d is greater than that of the heavy end 6c, and the heavy end 6c automatically rises to the upper limit position; at this time, the heavy end 6c of the longitudinal intermittent transfer mechanism 61 is lower than the dead point when the next floating ball moves, and stops the movement of the floating ball;

[0063] When the floating ball moves from the light end 6d to the circular arc baffle 2, the heavy end 6c freely falls back to the initial state due to gravity, and the reciprocating movement is realized to transport the floating ball from the upper rail to the lower rail;

[0064] S5. Floating ball distribution

[0065] When the floating ball moves to the assembly platform at the tail end of the horizontal rail 1f, the horizontal tail end U-shaped stop bar 5f blocks and the floating ball stops moving; after the staff completes the connection of the floating ball and the target object, the horizontal tail end U-shaped stop bar 5f is lifted, the floating ball is pushed into the water after the posture adjustment of the floating ball passing through the opening of the adjusting plate 6f and the posture adjustment of the floating ball passing through the opening of the adjusting plate 6f; The heavy end 6c in the horizontal intermittent transfer mechanism 62 at the tail end of the horizontal rail freely falls, and the following floating ball normally rolls to the assembly platform, and the same is true for all floating balls, completing the distribution of all floating balls.

[0066] The floating ball transfer device is composed of a roller rail 1, a circular arc baffle 2, a top grid 3, a limiting chain 4, a stop bar, an intermittent transfer mechanism, a speed reduction curtain 7, a support frame 8, and a ball collecting lifting device 9.

[0067] In order to realize the maximum efficiency and automation of floating ball storage and transportation, a device as shown in Figure 1 is designed. Due to the limited space, the floating ball storage needs to be placed in two layers and three columns, and the system is composed of five unpowered roller rails. The first longitudinal upper rail 1g and the first longitudinal lower rail 1h together place nine floating balls, the second longitudinal upper rail 1i and the second longitudinal lower rail 1j together place eleven floating balls, and the horizontal rail 1f places seven floating balls per layer. As shown in Figure 1 , the system can store 27 floating balls in total.

[0068] The structure of the roller rail is as shown in Figure 4 . The roller inclined plates 1a on each side are evenly distributed with rollers 1c to reduce friction. Since the floating ball is a "heart"-shaped ball, it can be stored and transported through the 135° support plates on both sides. In order to facilitate stacking, unpowered roller rails are suspended in the middle, and a 5° inclination is provided for the roller rail to provide power for the transportation of the floating ball.

[0069] Since the system relies on the inclination of the roller guide to provide the power for the transportation of the floating ball, the overall structure of the system is relatively high, and the stacking of the floating ball cannot be completed by manpower, so the crane needs to be used to complete the stacking by lifting the lifting appliance. First, the floating ball is placed in the lifting appliance, the bottom plate 9c of the lifting basket has a 5° inclination, so the floating ball will freely roll into the inside of the lifting basket 9b, ensuring that the floating ball will not roll out during lifting. After lifting the lifting appliance and the floating ball, the lifting appliance is connected to the floating ball inlet of the upper guide rail, the lifting basket hanging rod 9d is matched with the hook at the bottom of the inlet, and as the crane continues to lift, the rear end of the lifting appliance is lifted to put the floating ball into the roller guide, and the floating ball freely rolls to other roller guides, and the process is repeated to finally complete the stacking of all floating balls.

[0070] The storage of the floating ball relies on the roller guide, and all the blocking rods shown in Figure 2 、 Figure 3 are closed during storage. Since the height of the roller guide on the second layer is relatively high, the first end J-shaped blocking rod 5a on the upper layer, the tail end J-shaped blocking rod 5b and the J-shaped blocking rod sleeve 5d are designed, which only need to be pushed upward from below to open the blocking rod, and the blocking rod sliding groove is designed to prevent the blocking rod from tilting during the pushing process. The blocking rod at the tail end of the cross guide rail is a transverse tail end straight blocking rod 5e, which needs to be horizontally extracted when opened.

[0071] To prevent the floating ball from accidentally rolling out of the roller guide during storage and transportation, limit chains 4 are arranged on both sides of the roller guide, and the limit chains are arranged in different areas to facilitate adjustment when the system is not running smoothly. It is convenient to disassemble. Considering that there are waves during sea navigation, which is relatively bumpy, a top grid 3 is arranged on the roller guide to prevent the floating ball from jumping out from above.

[0072] The transportation of the floating ball relies on the roller guide 1, and during transportation, the transverse tail end straight blocking rod 5e shown in Figure 8 is opened first. Since the roller guide is arranged with a 5° inclination, and rollers are arranged in the inclined chute of the roller guide 1, the friction can be further reduced, so the floating ball can freely roll down, and the transportation of the floating ball of the transverse guide rail 1f is completed. Then, by opening the corresponding blocking rod, the lower layer is transported first, and then the upper layer is transported, and finally the transportation of all floating balls is completed.

[0073] In order to smoothly transport the floating ball on the upper roller guide to the lower roller guide, a circular arc guide rail 2 is designed, as shown in Figure 7 , the red floating ball is used to illustrate the transportation process. When the floating ball is transported to the circular arc guide rail, a small gap is left between the floating ball and the lower roller guide, which reduces the risk of the floating ball falling directly and the extrusion of the floating ball, reduces the damage to the floating ball and the roller guide, and prolongs the service life. In order to make the floating ball be transported from the upper layer to the lower layer in turn, a longitudinal intermittent transfer mechanism 61 is arranged.

[0074] The longitudinal intermittent transfer mechanism 61 is as shown in Figure 5 ,Figure 6 As shown, the overall structure is divided into heavy end 6c and light end 6d, the heavy end 6c is lighter than the light end 6d, so in the initial state, the heavy end 6c free fall, contact with the inner surface of the roller guide, to the lower limit position, at this time the heavy end 6c upper surface with the roller guide chute height keep level, the float ball can be free to roll, when the float ball device moves to the light end 6d, due to the weight of the float ball, the light end 6d weight is greater than the heavy end 6c, the heavy end 6c automatically up, when reaching the limit baffle, to the upper limit position, at this time the heavy end of the intermittent motion device is lower than the dead point of the float ball when moving, just can stop the movement of the float ball, when the float ball moves from the lower end to the circular arc guide rail 2, the heavy end 6c due to gravity, free fall, return to the initial state, so as to realize the float ball from the upper layer to the lower layer.

[0075] Due to the inclination of 5 degrees of the roller guide, and the float ball from the upper layer to the lower layer of the roller guide will produce a large kinetic energy, resulting in the float ball speed too fast, the movement is uncontrollable, arrange a thickness of the deceleration curtain 7, let the float ball can move in the lower layer of the roller guide with a lower speed.

[0076] When the float ball moves to the end of the assembly platform of the horizontal guide rail 1f, the float ball can stop moving due to the blocking of the horizontal tail end U-shaped baffle 5f. As shown in Figure 8 、 Figure 9 As shown, the heavy end 6c of the horizontal intermittent transfer mechanism 62 in the initial state, free fall, contact with the inner surface of the roller guide, to the lower limit position, at this time the heavy end 6c upper surface with the roller guide chute height keep level, the float ball can be free to roll, when the float ball device moves to the light end 6d, due to the weight of the float ball, the light end 6d weight is greater than the heavy end 6c, the heavy end 6c automatically up, to the upper limit position, at this time the heavy end of the intermittent motion device is lower than the dead point of the float ball when moving, just can stop the movement of the float ball; the float ball continues to move forward from the light end 6d, the adjustment plate 6f is uniformly distributed with some transfer rollers 6e, considering that the float ball is not a regular ball, the posture of the float ball may change when rolling, so some transfer rollers 6e are arranged to facilitate the adjustment of the posture of the float ball, so as to ensure the subsequent connection. After the float ball moves to the assembly platform, the heavy end 6c of the intermittent motion device automatically lifts up, at the same time, the horizontal tail end straight baffle 5e is inserted to block the following float ball.

[0077] When the staff completes the connection of the float ball and the target object, the horizontal tail end U-shaped baffle 5f is lifted up, the float ball is pushed into the water from the opening, the heavy end of the intermittent motion device is free to fall, the horizontal tail end U-shaped baffle 5f is put down, the horizontal tail end straight baffle 5e is pulled out, and the following float ball can normally roll to the assembly platform. By analogy, the placement of all float balls is completed.

[0078] Finally, it should be noted that the above-mentioned embodiments are only used to illustrate the technical solutions of the present application, and are not intended to limit the present application; although the present application has been described in detail with reference to the above-mentioned embodiments, those skilled in the art should understand that the technical solutions recorded in the above-mentioned embodiments can still be modified, or some or all of the technical features can be replaced by equivalent replacements; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application.

The float is placed in the basket (9b), and the bottom plate (9c) of the basket has an inward tilt angle, so the float will roll freely into the basket (9b); After the ball-collecting device (9) and the float are lifted, the ball-collecting device (9) approaches the float inlet of the upper guide rail. The basket hanging rod (9d) engages with the hook at the bottom of the roller track inlet. As the crane continues to lift, the rear end of the basket (9b) tilts up, placing the float into the upper guide rail. The float rolls freely to complete the stacking of all the floats. S2. Storage of the float The float is stored on the transverse and longitudinal guide rails, and all levers are closed during storage; S3. Transport of buoys During transport, first open the transverse end straight stop bar (5e) at the end of the transverse guide rail (1f). Since the guide rail structure is inclined and rollers (1c) are arranged on the roller inclined plate (1a), the floats roll down freely, and the floats of the transverse guide rail (1f) are transported. Then open the lower end J-shaped stop bar (5c) to transport the floats of the lower guide rail first. Then open the upper end J-shaped stop bar (5b) to transport the floats of the upper guide rail until all the floats are transported. S4. Intermittent transfer mechanism transfer float In the initial state of the longitudinal intermittent transfer mechanism (61) at the tail end of the upper guide rail, the heavy end (6c) falls freely and contacts the inner surface of the guide rail base plate (1b), reaching the lower limit position; the float rolls freely over the heavy end (6c) and the transfer shaft (6b). When the float moves to the light end (6d), the weight of the float and the light end (6d) is greater than the weight of the heavy end (6c), and the heavy end (6c) automatically tilts up, reaching the upper limit position; at this time, the heavy end (6c) of the longitudinal intermittent transfer mechanism (61) abuts against the next float, causing it to stop moving. When the float moves from the light end (6d) to the arc baffle (2), the heavy end (6c) falls freely due to gravity and returns to the initial state. This process is repeated to transport the float from the upper guide rail to the lower guide rail. S5. Float deployment When the float moves to the assembly platform at the tail end of the transverse guide rail (1f), the transverse tail end U-shaped stop bar (5f) blocks it, and the float stops moving. After the worker completes the connection between the float and the target object, the transverse tail end U-shaped stop bar (5f) is lifted, and the float is transferred by the transverse intermittent transfer mechanism (62). In the initial state, the heavy end (6c) falls freely and contacts the inner surface of the guide rail base plate (1b), reaching the lower limit position. The float rolls freely over the heavy end (6c) and the transfer shaft (6b). When the float moves to the light end (6d), the weight of the float and the light end (6d) is greater than the weight of the heavy end (6c). The heavy end (6c) automatically tilts up, reaches the upper limit position, and stops the next float. After the float is adjusted by the attitude of the transfer roller (6e) on the adjustment plate (6f), it is pushed into the water. Then the heavy end (6c) falls freely. Repeat the above float deployment steps to complete the deployment of all floats.
