Description

Technical Field

[0001] This utility model belongs to the field of marine technology, and in particular relates to an automatic locking support for a ship hoisting bracket. Background Technology

[0002] Ship lifting bracket support is a structural support device used to lift and secure ship components or equipment. It is widely used in shipbuilding, repair and transportation. The device is usually made of high-strength materials, has good load-bearing capacity and stability, and can effectively disperse the stress generated during the lifting process, reducing the risk of structural deformation and damage.

[0003] Traditional ship lifting brackets generally lack automatic locking structures. During the lifting process, the towing rope may slip due to vibration, uneven force, or external interference, making it impossible to effectively control the stability of the cargo. This can lead to cargo falling, equipment damage, or even safety accidents. Since traditional brackets mainly rely on manual operation or simple mechanical fixing devices, their locking effect is greatly affected by the precision of operation and external force. They also have a slow response speed when dealing with emergencies, making it difficult to meet the safety and stability requirements of modern ship transportation. Therefore, we propose an automatic locking support for ship lifting brackets. Utility Model Content

[0004] To address the problems existing in the prior art, this utility model provides an automatic locking support for ship hoisting brackets.

[0005] This utility model is implemented as follows: an automatic locking support for a ship lifting bracket includes a support plate for fixing to the ship plate, and further includes: a support frame rotatably mounted on the support plate; a wire reel rotatably mounted inside the support frame; and an automatic locking assembly disposed on one side of the support frame. The automatic locking assembly includes a turntable rotatably mounted on one side of the bottom of the support frame, and one side of the turntable is fixedly connected to the wire reel. When the turntable rotates at a loss, a locking plate rotatably mounted outside the turntable extends under the influence of centrifugal force and engages with a limiting ring fixed on one side of the support frame, thereby realizing an automatic locking emergency stop operation of the wire reel.

[0006] As a preferred embodiment of this utility model, a triangular plate is fixedly connected to one side of the turntable, and the three sides of the triangular plate are respectively connected to the inner side of a card plate by springs.

[0007] As a preferred embodiment of this utility model, the limiting ring has several slots inside. When the turntable rotates at high speed, the locking plate overcomes the spring tension and engages with the slots of the limiting ring to perform an emergency stop action.

[0008] As a preferred embodiment of this utility model, a large gear is fixedly connected to the lower part of the support frame, and a small gear is meshed with one side of the large gear.

[0009] In a preferred embodiment of this invention, the large gear and the small gear are rotatably mounted on the upper part of the support plate, and a first motor is fixedly mounted on the upper part of the mounting bracket fixed on the upper part of the support plate. The output end of the first motor is fixedly connected to the small gear. When the motor is started, it controls the support bracket to perform an angle rotation action.

[0010] As a preferred embodiment of this utility model, a second motor is fixedly installed on one side of the bottom of the support frame, and the output end of the second motor passes through the support frame and is fixedly connected to the wire-laying drum. Several guide wheels are rotatably installed on one side of the support frame, and the traction rope of the wire-laying drum passes through several of the guide wheels at one time to perform the lifting action of the item.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] When the cable reel rotates at high speed due to sudden force changes or stalling, the external turntable also rotates at high speed, which in turn drives the clamping plate on the outside of the turntable to generate centrifugal force. With the action of centrifugal force, the clamping plate extends outward and inserts into the limiting ring fixed on one side of the support frame, forming a mechanical limit, thereby achieving rapid braking of the cable reel and preventing the traction rope from continuing to slide due to inertia and causing the cargo to fall. In addition, this structure can be automatically triggered in emergency situations without manual intervention, improving the speed and reliability of locking response, while avoiding the delay problem of traditional manual locking, making ship lifting operations safer and more efficient, and improving the overall reliability and stability of the operation.

[0018] To further understand the utility model content, features and effects of this utility model, the following embodiments are provided, and detailed descriptions are given in conjunction with the accompanying drawings.

[0019] The structure of this utility model will now be described in detail with reference to the accompanying drawings.

[0020] like Figures 1 to 4 As shown in the figure, an automatic locking support for a ship hoisting bracket provided by this utility model includes a support plate 1 for fixing to the ship plate, and further includes: a support frame 2 rotatably installed on the support plate 1; a wire reel 3 rotatably installed inside the support frame 2; and an automatic locking assembly 6 disposed on one side of the support frame 2. The automatic locking assembly 6 includes a turntable 601 rotatably installed on one side of the bottom of the support frame 2, and one side of the turntable 601 is fixedly connected to the wire reel 3. When the rotation stalls, a locking plate 603 rotatably installed outside the turntable 601 extends under the influence of centrifugal force and inserts into a limiting ring 605 fixed on one side of the support frame 2 to realize the automatic locking emergency stop operation of the wire reel 3.

[0021] The aforementioned automatic locking support for a ship lifting bracket uses an automatic locking assembly 6 to control the stall of the wire reel 3, thereby improving the safety and stability of the lifting operation. The device includes a support plate 1 fixed to the ship's deck, on which a support frame 2 is rotatably mounted, giving the entire bracket a certain degree of adaptability and stability. The wire reel 3 is housed inside the support frame 2, used to control the release and tightening of the traction rope 4, and to ensure stability during the lifting process. An automatic locking assembly 6 is installed on one side of the support frame 2 to achieve an emergency locking function for the wire reel 3. The key structure of the automatic locking assembly 6 includes a turntable 601, one side of which is fixedly connected to the wire reel 3, allowing it to rotate synchronously with the wire reel 3. When the wire reel 3 rotates at high speed due to sudden force changes or stalling, the outer turntable 601 also rotates at high speed, which in turn drives the clamping plate 603 on the outside of the turntable 601 to generate centrifugal force. With the action of centrifugal force, the clamping plate 603 extends outward and inserts into the limiting ring 605 fixed on one side of the support frame 2, forming a mechanical limit, thereby realizing the rapid braking of the wire reel 3 and preventing the traction rope 4 from continuing to slide due to inertia and causing the cargo to fall. In addition, this structure can be automatically triggered in an emergency without manual intervention, which improves the speed and reliability of locking response, while avoiding the delay problem of traditional manual locking, making ship lifting operations safer and more efficient, and improving the overall reliability and stability of the operation.

[0022] In this embodiment, a triangular plate 602 is fixedly connected to one side of the turntable 601. The three sides of the triangular plate 602 are respectively connected to the inner side of a locking plate 603 through springs 604. A plurality of slots 606 are provided inside the limiting ring 605. When the turntable 601 rotates at high speed, the locking plate 603 overcomes the tension of the spring 604 and engages with the slots 606 of the limiting ring 605 to perform an emergency stop action.

[0023] By utilizing the synergistic action of turntable 601, triangular plate 602, spring 604, and clamping plate 603, the automatic locking emergency stop of the wire reel 3 in a stall state is achieved. Triangular plate 602 is fixedly connected to one side of turntable 601. The three sides of triangular plate 602 are connected to the inner side of clamping plate 603 via springs 604, keeping clamping plate 603 in a retracted state under normal conditions, preventing contact with the limit ring 605. When the wire reel 3 rotates at high speed due to external force or stall, the fixedly connected turntable 601 rotates synchronously at high speed. The high-speed rotation of turntable 601 causes… Under the action of centrifugal force, the clamping plate 603 on the triangular plate 602 overcomes the tension of the spring 604 and extends outward, thereby engaging with the groove 606 inside the limiting ring 605 fixed on the support frame 2 to form a mechanical limit, realizing the automatic locking and emergency stop of the unloading drum 3, effectively preventing the traction rope 4 from slipping and avoiding the falling of goods or damage to equipment. This design relies on centrifugal force for automatic triggering, without the need for external power or manual intervention, ensuring a safer and more reliable hoisting process, while improving the response speed in emergency situations and enhancing the overall safety and stability of the operation.

[0024] In this embodiment, a large gear 10 is fixedly connected to the lower part of the support frame 2, and a small gear 9 is meshed with one side of the large gear 10. The large gear 10 and the small gear 9 are rotatably mounted on the upper part of the support plate 1. A first motor 8 is fixedly mounted on the upper part of the mounting bracket 7 fixed on the upper part of the support plate 1. The output end of the first motor 8 is fixedly connected to the small gear 9. When the motor starts, it controls the support frame 2 to perform an angle rotation action. A second motor 11 is fixedly mounted on one side of the bottom of the support frame 2. The output end of the second motor 11 passes through the support frame 2 and is fixedly connected to the wire reel 3. Several guide wheels 5 are rotatably mounted on one side of the support frame 2. The traction rope 4 of the wire reel 3 passes through several guide wheels 5 at one time to perform the lifting action of the item.

[0025] The angle of the support frame 2 is controlled by a motor-driven gear mechanism. At the same time, the stable hoisting of the item is achieved by using the wire reel 3 and guide wheel 5 system. First, a large gear 10 is fixedly connected to the lower part of the support frame 2. A small gear 9 is meshed with one side of the large gear 10. Both the large gear 10 and the small gear 9 are rotatably mounted on the upper part of the support plate 1. When the first motor 8 fixedly mounted on the support plate 1 is started, its output end drives the small gear 9 to rotate. The small gear 9 drives the large gear 10 to rotate synchronously through gear meshing, thereby realizing the adjustment of the angle of the support frame 2. This allows the hoisting equipment to change the angle according to the requirements, so as to adapt to different working environments and improve the flexibility and accuracy of hoisting.

[0026] A second motor 11 is fixedly installed on one side of the bottom of the support frame 2. The output end of the second motor 11 passes through the support frame 2 and is fixedly connected to the wire reel 3. When the second motor 11 starts, it directly drives the wire reel 3 to rotate, realizing the release and tightening of the traction rope 4. This ensures that the cargo can be lifted and lowered smoothly during the hoisting process, avoiding swaying or loss of control, and further improving the safety of the hoisting operation. In addition, in order to ensure that the traction rope 4 always maintains stable operation during the release and tightening process, several guide wheels 5 are also rotatably installed on one side of the support frame 2, so that the traction rope 4 passes through the guide wheels 5 in sequence, thereby reducing the swing or misalignment of the rope during operation and improving the accuracy and stability of the hoisting. This device uses a motor to control gear transmission and the wire reel 3, and combines the guide wheels 5 to optimize the path of the traction rope 4, making the hoisting process safer, more controllable and efficient, and greatly improving the adaptability and operational capability of the ship hoisting bracket.

[0027] The working principle of this utility model:

[0028] In use, the automatic locking assembly 6 controls the stall of the wire reel 3, thereby improving the safety and stability of the hoisting operation. This device includes a support plate 1 fixed to the ship's deck, on which a support frame 2 is rotatably mounted, giving the entire support frame a certain degree of adaptability and stability. The wire reel 3 is housed inside the support frame 2, used to control the release and tightening of the traction rope 4, and to ensure stability during hoisting. The automatic locking assembly 6 is installed on one side of the support frame 2 to achieve an emergency locking function for the wire reel 3. The key structure of the automatic locking assembly 6... The system includes a turntable 601, on one side of which a wire-feeding drum 3 is fixedly connected, allowing it to rotate synchronously with the wire-feeding drum 3. When the wire-feeding drum 3 rotates at high speed due to sudden force changes or stalling, the external turntable 601 also rotates at high speed, thereby driving the clamping plate 603 on the outside of the turntable 601 to generate centrifugal force. With the action of centrifugal force, the clamping plate 603 extends outward and inserts into the limiting ring 605 fixed on one side of the support frame 2, forming a mechanical limit, thereby achieving rapid braking of the wire-feeding drum 3 and preventing the traction rope 4 from continuing to slide due to inertia, causing the goods to fall.
