Description

Technical Field

[0001] This utility model relates to the field of engineering construction technology, and in particular to a high-efficiency mechanized ship launching pulley. Background Technology

[0002] The launching of a ship is a crucial and landmark stage in the shipbuilding process. The preceding stage involves construction on a land-based slipway or in a water-based dock. Once most of the shipbuilding work is complete, the ship is moved from the construction area to the water area – this is the launching process. Based on the principle of launching, ships can be categorized into four main types: gravity launching, floating launching, mechanized launching, and airbag launching. Currently, mechanized launching is mostly used for larger ships. Its launching trolleys are integral, consisting of one or two trolleys with multiple rows of tracks; each trolley is large and expensive.

Detailed Implementation

[0017] like Figure 1-4 In this invention, a highly efficient mechanized ship launching pulley includes a detachable support frame 4 mounted on a pulley 3. The support frame 4 is supported on the lower part of a ship 8. The pulley 3 and the track 2 on the grid beam 1 are slidably connected. The lower part of the support frame 4 is also detachably equipped with a jack 6, which is connected to the pulley 3 via a transfer frame 5. The position of the pulleys 3 on two adjacent grid beams 1 can be adjusted to accommodate ships 8 of different widths. A monitoring component 7 is also provided between two adjacent pulleys 3 to detect the relative position between the two pulleys 3.

[0018] Since the size and width of the vessel 8 vary, this solution can be adjusted according to the width of the vessel 8. By arranging the pulleys 3 in different forms, the launching needs of the vessel 8 can be fully met. The adjustment is simple, the performance is good, and the different pulleys 3 are independent of each other, making the control operation more flexible.

[0019] Whether coaxial or staggered arrangement is adopted, it is necessary to ensure that the position of each pulley 3 is in a precise position so that the load can be evenly distributed during the launching of the ship 8, ensuring sufficient support for the ship 8 and completing the launching operation smoothly and safely.

[0020] like Figure 5-10 In the preferred embodiment, one end of the trolley 3 is provided with a locking hook 21, which is connected to the third motor 24 via a cable 23. The third motor 24 is located on the platform 16. The middle part of the load-bearing frame 4 is provided with a weight-reducing groove 401, and the top of the load-bearing frame 4 is evenly provided with multiple clearance openings 402. The structure of the adapter frame 5 is the same as that of the load-bearing frame 4. The top of the adapter frame 5 is connected to the balance plate 22 via two jacks 6, and the balance plate 22 is connected to the load-bearing frame 4 via screws 20.

[0021] When a coaxial arrangement is adopted, the participation of the adapter frame 5 and jack 6 is not required, and the pulley 3 itself can complete the support and launching operation of the vessel 8. When a staggered arrangement is adopted, since there will be a height difference between adjacent pulleys 3, the adapter frame 5 and jack 6 can be used to supplement the difference, ensuring that the height of the uppermost support surface of adjacent pulleys 3 is consistent, thus ensuring the stability of the support. The screws 20 are used for installation and removal, and the adjustment is convenient. When the vessel 8 is pushed from the factory onto the pulley 3, the third motor 24 is controlled to raise and lower the cable 23 of the winch. As the pulley 3 gradually enters the adjacent water area from the platform 16 on the track 2, the vessel 8 completely detaches from the pulley 3 under the action of buoyancy after completing the water entry and draft, thus completing the launching operation.

[0022] like Figure 11-12 In a preferred embodiment, the monitoring component 7 includes a first cavity 701 and a second cavity 702. The tops of the first cavity 701 and the second cavity 702 are respectively installed in the weight reduction groove 401 via a second motor 705. A transmitter 703 and a receiver 704 are respectively installed on the outside of the first cavity 701 and the second cavity 702. The transmitter 703 and the receiver 704 cooperate to detect the position between two adjacent trolleys 3.

[0023] Since different arrangement methods are required, the second motor 705 can flexibly adjust its own angle to change the respective positions of the transmitter 703 and the receiver 704, ensuring that the receiver 704 can accurately receive the light from the transmitter 703 in the initial state, thereby determining its own relative position accurately, which is conducive to timely adjustments by construction personnel. At the same time, the second motor 705 is a servo motor, which can ensure the rotation accuracy through its own encoder angle, thereby using different trolleys 3 to complete the accurate arrangement.

[0024] In the preferred embodiment, a brake assembly 10 is detachably mounted on the grid beam 1. One side of the brake assembly 10 is connected to the trolley 3 via a hook 9, and the other side of the brake assembly 10 is connected to the first motor 12 via a traction rope 11. The first motor 12 is located on the platform 16. The brake assembly 10 is used to provide safety protection for the trolley 3. The first motor 12 is connected to a winding drum 15 via an output shaft 14. The traction rope 11 is wound around the winding drum 15. The platform 16 is also provided with a fixed pulley 13, which is supported on the underside of the traction rope 11.

[0025] When the trolley 3 becomes uncontrollable, the braking assembly 10 comes into play, providing the first layer of safety protection to prevent the risk from escalating. The first motor 12 controls the traction rope 11 to change the position of the braking assembly 10. In the initial state, the first motor 12 slowly releases the traction rope 11, and the braking assembly 11 moves down with the trolley 3. At the same time, the braking assembly 11 maintains a stable distance from the trolley 3 and does not interfere with the downward movement of the trolley 3. When the trolley 3 becomes uncontrollable, that is, when the cable 23 breaks, the trolley 3 tends to slip under its own weight and gradually accelerates, causing the braking assembly 10 to exert a downward force on the traction rope 11. At this time, the traction rope 11 applies a counter-pulling force to the first motor 12. Under the action of the dragging torque, the first motor 12 forms the second layer of safety protection.

[0026] like Figure 13-18 In the preferred embodiment, the trolley 3 includes a small end 301 and a large end 302. The small end 301 and the large end 302 are respectively connected to the bearing surface 309 through the inclined surface 308. The load-bearing frame 4 is set on the upper side of the bearing surface 309. Multiple rollers 303 are symmetrically arranged at the bottom of the trolley 3. The rollers 303 slide on the track 2. Multiple sliding grooves 304 are arranged in parallel on the lower side of the trolley 3. A strong magnetic sheet 17 is arranged inside the sliding groove 304. The pull plate 305 slides in the sliding groove 304.

[0027] During the above process, the pull plate 305 and the trolley 3 have a certain magnetic force. When the trolley 3 goes out of control, the brake assembly 10, the hook 9, and the traction rope 11 form the first and second layers of safety protection. If the trolley 3 continues to slide down, the pull plate 305 gradually separates from the trolley 3. Through the magnetic force, it further slows down the downward movement of the trolley, making it easier for construction personnel to take appropriate measures according to different situations and ensure the safety of construction.

[0028] In the preferred embodiment, a plurality of mounting holes 307 are provided through the lower side of the slide 304, and a through groove 306 is provided through the pull plate 305. The screw 20 passes through the mounting holes 307 and the through groove 306. The outer side of the large end 302 and the inclined surface 308 is also provided with a first safety airbag 18 and a second safety airbag 19, and the state of the first safety airbag 18 and the second safety airbag 19 is controlled by the position of the pull plate 305.

[0029] When the pull plate 305 reaches its limit position in the slide 304, the pull plate 305 is connected to the first safety airbag 18 and the second safety airbag 19 through the control line. The first safety airbag 18 and the second safety airbag 19 located behind the pull plate 305 are detonated, which provides protection for the trolley 3 before it falls into the water. This is the third layer of safety protection, which delays the process of the trolley 3 falling directly into the water and sinking to the bottom, and provides emergency time for construction personnel. Since the salvage cost of the trolley 3 falling directly into the water and sinking to the bottom is very expensive, this process directly reduces the cost of emergency response.

[0030] In a preferred embodiment, the end of the pull plate 305 is provided with a hanging ear 310, the pull hook 9 includes a fixing hook 901 and a pull cable 902, the end of the pull cable 902 is provided with a first mounting ring 903, the first mounting ring 903 is sleeved on the brake assembly 10, and the fixing hook 901 is hung on the hanging ear 310. The brake assembly 10 includes a bidirectional telescopic cylinder 1001, and push rods 1007 are respectively provided on both sides of the bidirectional telescopic cylinder 1001. The push rods 1007 are slidably connected to the rail 2 through a C-shaped plate 1002. The traction rope 11 includes a rope body 1101, and a second mounting ring 1105 is provided on one side of the rope body 1101. The second mounting ring 1105 is sleeved on the brake assembly 10.

[0031] Screw 20 is an explosion screw. When the pull plate 305 reaches the limit position, the shear force on screw 20 reaches the design value, screw 20 explodes and breaks, and pull plate 305 is separated from the trolley. This avoids the problem of excessive impact from the trolley 3 sliding down, which would cause damage to the track 2 along with the brake assembly 10, reduce component loss, and abandon trolley 3 to protect the safety of other equipment.

[0032] In a preferred embodiment, the lower part of the C-shaped plate 1002 is provided with a hook plate 1003 and a baffle 1004. The hook plate 1003 and the baffle 1004 are connected to the C-shaped plate 1002 to form a channel 1005. The cross-section of the track 2 is I-shaped. The width of the channel 1005 is greater than the top width of the track 2. The lower part of the C-shaped plate 1002 is rotatably provided with a traveling wheel 1006, which is used to move the position of the brake assembly 10.

[0033] In the initial state, the brake assembly 10 is extended, and the traveling wheel 1006 is attached to the inner side of the track 2, ensuring its own position while moving smoothly and stably as the trolley 3 moves downward. The cable 902 provides a buffer and force relief for the hook 9, avoiding excessive instantaneous impact caused by the use of hard materials, which could cause irreversible damage to the brake assembly 10. The traction rope 11 captures the brake assembly 10. When the trolley 3 becomes uncontrollable, the brake assembly 10 retracts, and the outer side of the channel 1005 is attached to the outer side of the track 2, completing the clamping action. The brake assembly 10 itself is locked on the track 2. If the trolley 3 continues to move downward at this time, the brake assembly 10 moves downward with the track 2, and the traction rope 11 drives the first motor 12 to form a dragging action, dragging in the opposite direction to delay the risk of the trolley 3 moving downward, until the trolley 3 stops or completely detaches from the track 2 and falls into the water.

[0034] In a preferred embodiment, ribs 1012 are symmetrically arranged on the lower part of the C-shaped plate 1002. The ribs 1012 and the C-shaped plate 1002 are connected to form a cavity 1011. A shaft 1010 is arranged inside the cavity 1011. A traveling wheel 1006 is sleeved on the shaft 1010. A gap is provided between the end of the baffle 1004 and the end of the traveling wheel 1006.

[0035] The cavity 1011 reduces the overall weight, while the rib 1012 improves the overall lateral support strength. The gap between the end of the baffle 1004 and the end of the traveling wheel 1006 avoids jamming and friction with the track 2 during normal travel, which would affect the overall operation. At the same time, the gap is reasonably designed so that the direction of the gap can be adjusted in time in case of emergencies, thereby completing the overall locking and braking.

[0036] In a preferred embodiment, the bidirectional telescopic cylinder 1001 is provided with a plurality of first mounting grooves 1008 and second mounting grooves 1009 through a through-and-through interval. The first mounting ring 903 is fitted inside the first mounting groove 1008. The end of the rope body 1101 is provided with a first locking ring 1102. The first locking ring 1102 is fitted onto the buffer rope 1104 through the second locking ring 1103. The second mounting ring 1105 is provided at the end of the buffer rope 1104 and is fitted inside the second mounting groove 1009.

[0037] The first mounting ring 903 and the second mounting ring 1105 are subjected to forces at multiple locations, forming a combined force to ensure a balanced tension on the trolley 3. The traction rope 11, through the first locking ring 1102 and the second locking ring 1103, also plays a role in unloading force, ensuring the safe use of the brake assembly 10 and avoiding large instantaneous impacts.

[0038] The above embodiments are merely preferred technical solutions of this utility model and should not be considered as limitations on this utility model. The protection scope of this utility model should be the technical solution described in the claims, including equivalent substitutions of the technical features described in the claims. That is, equivalent substitutions and improvements within this scope are also within the protection scope of this utility model.
