Description

Technical Field

[0001] This invention relates to the field of lifting devices, specifically to an intelligent lifting device for mechanical installation on ship decks. Background Technology

[0002] A lifting device is a multi-action hoisting mechanism that vertically lifts and horizontally moves heavy objects within a certain range. Primarily used for hoisting goods, lifting devices are frequently installed on ship decks as tools for transporting goods between the ship and the cargo hold; they are also known as "deck cranes." Through the intermittent movements of the crane, they perform cyclical operations such as picking up, rotating, and unloading materials within a defined environment. Using lifting devices effectively reduces manual labor, and intelligent control systems enable technologically advanced transportation. Currently, intelligent lifting devices for ship decks on the market have the following main drawbacks:

[0003] 1. It mainly consists of a hoisting mechanism, a control device, a rotating mechanism, an installation mechanism, and a frame. The operation of the hoisting and rotating mechanisms is controlled by the control device, which facilitates operation by staff. However, the intelligent lifting devices for ship deck machinery installation currently on the market still have the following problems:

[0004] 2. Both methods involve first fixing the mounting plate to the deck, and then placing the main body of the lifting device on the mounting plate. However, the connection between the main body of the lifting device and the installation mechanism is relatively simple, using only a vertical snap-fit ​​method for fixation. The connection is not strong enough, which can easily make the installation of the heavy lifting device body unstable and inconvenient for subsequent lifting operations.

[0005] 3. Without a buffer device, the lifting equipment inevitably sways up and down when operating on a ship. Without a buffer device, the heavy lifting equipment will directly hit the mounting plate, causing damage to the mounting plate. In severe cases, it can damage the ship's deck, which cannot guarantee the service life of the equipment and increases the probability of maintenance.

[0006] 4. It can rotate horizontally, which makes it easy to move the lifted heavy objects horizontally. However, when the rotation is too fast, there is no self-locking device to stop the operation of the rotation device. This causes the lifted heavy objects to shake too much when the rotation is too fast, making them easy to fall off the hook, which will damage the heavy objects and affect the quality of transportation. Moreover, the heavy objects will have a great destructive force on the deck due to their excessive weight, which seriously threatens the service life of the deck. Summary of the Invention

[0007] The purpose of this invention is to provide an intelligent lifting device for ship deck machinery installation, to solve the problems mentioned in the background art. Currently available intelligent lifting devices for ship deck machinery installation on the market first fix the mounting plate to the deck, and then place the main body of the lifting device on the mounting plate. However, the connection between the main body of the lifting device and the installation mechanism is relatively simple, using only a vertical snap-fit ​​method for fixation. The connection is not strong enough, which can easily make the installation of the heavy lifting device unstable, making subsequent lifting operations inconvenient. Moreover, there is no buffer device. When operating the lifting device on a ship, it is inevitable that the lifting device will sway up and down. Without a buffer device, the heavy lifting device will directly hit the mounting plate, causing damage to the mounting plate.

[0008] To achieve the above objectives, the present invention provides the following technical solution:

[0009] An intelligent lifting device for ship deck machinery installation includes an installation device, connecting bolts on both sides of the installation device, an installation cylinder on the upper surface of the installation device, a connecting plate at the upper end of the installation cylinder, a dust cover connected to the upper end of the connecting plate, a rotating platform on the dust cover, a device body at the upper end of the rotating platform, a locking mechanism inside the installation cylinder, a retraction device between two locking mechanisms, a buffer device at the lower end of the locking mechanism, a motor within the space enclosed by the dust cover and the rotating platform, a drive shaft at the bottom of the motor, a ratchet on the drive shaft, a self-locking structure on the outer ring of the ratchet, a control device connected to the device body, and a lifting device on the device body.

[0010] Furthermore, the mounting device includes a fixing plate and a connecting rod. The two fixing plates are connected by the connecting rod. Each fixing plate is provided with two symmetrically distributed fixing bolts. The fixing plate is provided with two mounting cylinders. The upper part of the mounting cylinder is trumpet-shaped. The straight cylindrical area of ​​the mounting cylinder engages with the locking rod at the bottom of the connecting plate.

[0011] Furthermore, the bottom of the locking rod is provided with a slot, and the locking rod is fixedly connected to the locking mechanism through the slot. The locking mechanism includes a T-shaped rod, a compression spring, and a pull rope. The length of the T-shaped rod is greater than the width of the mounting cylinder. A compression spring is provided between the outer wall of the mounting cylinder and the end of the T-shaped rod. The width of the slot of the locking rod is greater than the width of the two T-shaped rods. An elastic pull rope is provided at the end of the T-shaped rod away from the mounting cylinder.

[0012] Furthermore, the end of the pull rope that is not connected to the T-shaped rod is set inside the recovery device. The recovery device includes a first winding wheel, a second winding wheel, and a main shaft. The lower end of the first winding wheel and the upper end of the second winding wheel are respectively connected to the pull rope on the opposite side and the closest distance away. The first winding wheel and the second winding wheel rotate coaxially through the main shaft, and a small motor is provided on the main shaft.

[0013] Furthermore, the bottom of the locking rod is in contact with the buffer device, which includes a pressing block, a connecting rod, a central shaft, a movable block, a slide rod, and a buffer spring. The two sides of the pressing block are connected to the movable block through the connecting rod. Both ends of the connecting rod are provided with a rotating shaft, and a central shaft is provided at the center of the connecting rod. The central shaft is supported in the inner wall of the mounting cylinder. A slide rod is provided through the movable block, and a buffer spring is connected to the upper end of the movable block. A damper is provided at the upper end of the buffer spring.

[0014] Furthermore, the diameter of the ratchet is smaller than the length of the dust cover, and the dust cover is provided with a track for the rotating platform to rotate, the rotating platform being cylindrical.

[0015] Furthermore, a self-locking structure is provided in each of the four positions of the ratchet: front, back, left, and right. The self-locking structure includes a thorn, an eccentric shaft, a moving shaft, an electric telescopic rod, and a compression spring. The structure of the thorn matches the structure of the ratchet. One end of the thorn is rotatably and fixedly connected to the eccentric shaft with the eccentric shaft as the rotation axis. The other end of the thorn is fixedly connected to the moving shaft. The moving shaft is connected to the electric telescopic rod, and the electric telescopic rod is fixedly connected to the connecting plate.

[0016] Furthermore, the lifting device includes a second motor, a drum, a steel cable, and a hook. The steel cable and the hook are an integrated structure. The steel cable is connected to the drum through multiple pulleys. The rotation shaft of the drum is connected to the output shaft of the second motor.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows: The intelligent lifting device for ship deck machinery installation; 1. An installation cylinder is set on the fixing plate, and the locking rod at the bottom of the device body is inserted into it to complete the initial locking. During this process, the pushing of the locking rod will squeeze the T-shaped rod, causing the T-shaped rod to move to the left, which just stretches the compression spring. When it encounters the reserved slot on the locking rod, the T-shaped rod moves to the left under the action of the compression spring, which just fixes the locking rod laterally, thus performing a second locking of the device body. Compared with the traditional locking method, the double locking structure is more robust, making the connection between the fixing plate and the device body more stable, which is more conducive to ensuring the normal operation of subsequent lifting work.

[0018] 2. The engaged rod contacts the compression block after installation. When there is up-and-down shaking, it will squeeze the compression block. The two ends of the compression block are connected to the movable block through connecting rods. When the compression block descends, the connecting rod rotates around the central axis, causing the movable block to slide upward on the slide rod and squeeze the buffer spring. The buffer spring stores energy. When the shaking disappears, the damper on the buffer spring releases the energy and drives the above parts to reset. This buffer device can effectively slow down the downward impact speed of the engaged rod, ensuring that the device is not damaged and helping to extend the service life of the device.

[0019] 3. The motor drives the ratchet to rotate, which in turn drives the main body of the device to rotate via the rotating platform. When the speed is too fast, the electric telescopic rod is activated to make the thorn rotate around the eccentric shaft, so that the thorn can lock the ratchet and restrict its rotation, thereby achieving the purpose of self-locking. This ensures that the rotation can be stopped suddenly, improving the safety of use and effectively preventing objects from falling due to the inability to stop the rotation due to excessive speed.

[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] Please see Figure 1-8 This invention provides a technical solution: an intelligent lifting device for the installation of ship deck machinery, comprising an installation device 1, connecting bolts 2 on both sides of the installation device 1, an installation cylinder 7 on the upper surface of the installation device 1, a connecting plate 3 on the upper end of the installation cylinder 7, a dust cover 4 connected to the upper end of the connecting plate 3, a rotating platform 5 on the dust cover 4, a device body 6 on the upper end of the rotating platform 5, a locking mechanism 8 inside the installation cylinder 7, a recovery device 9 on the left side of the two locking mechanisms 8, a buffer device 10 at the lower end of the locking mechanism 8, a motor 11 on the upper end of the dust cover 4, a drive shaft 12 at the bottom of the motor 11, a ratchet 13 on the outside of the drive shaft 12, a self-locking structure 14 on the outer ring of the ratchet 13, a control device 15 on the left side of the device body 6, and a lifting device 16 on the upper end of the control device 15.

[0035] The mounting device 1 includes a fixing plate 101 and a connecting rod 102. The two fixing plates 101 are connected by the connecting rod 102. Each fixing plate 101 is provided with two symmetrically distributed fixing bolts 103. The fixing plate 101 is provided with two equally sized mounting cylinders 7. The mounting cylinders 7 are flared with large openings. The straight cylindrical area of ​​the mounting cylinder 7 is engaged with the locking rod 301 at the bottom of the connecting plate 3. The connection is made more stable by four locking groups.

[0036] The bottom of the locking rod 301 is provided with a slot, which can lock the locking mechanism 8. The locking mechanism 8 includes a T-shaped rod 801, a compression spring 802, and a pull rope 803. The length of the T-shaped rod 801 is greater than the width of the mounting cylinder 7, and the compression spring 802 is connected between the outside of the mounting cylinder 7 and the T-shaped rod 801. The width of the slot of the locking rod 301 is greater than the width of the two T-shaped rods 801, and the pull rope 803 is connected to the left side of the T-shaped rod 801. The pull rope 803 has a certain degree of tensile strength, which allows the T-shaped rod 801 to extend and retract back and forth, thereby locking the locking rod 301 a second time.

[0037] The end of the pull rope 803 is located inside the recycling device 9, which includes a first winding wheel 901, a second winding wheel 902, and a main shaft 903. The first winding wheel 901 is connected to the pull rope 803 on the left side from the bottom, and the second winding wheel 902 is connected to the pull rope 803 on the right side from the top. The first winding wheel 901 and the second winding wheel 902 rotate coaxially through the main shaft 903, and a small motor is installed on the main shaft 903 to ensure that the pull rope 803 is always in a taut state while performing winding.

[0038] The bottom of the locking rod 301 is in contact with the buffer device 10. The buffer device 10 includes a pressing block 1001, a connecting rod 1002, a central shaft 1003, a movable block 1004, a slide rod 1005, and a buffer spring 1006. The two sides of the pressing block 1001 are connected to the movable block 1004 through the connecting rod 1002. Both ends of the connecting rod 1002 are provided with a rotating shaft, and the central shaft 1003 is provided at the center point of the connecting rod 1002. The central shaft 1003 is supported in the inner wall of the mounting cylinder 7. The slide rod 1005 is provided through the movable block 1004, and the upper end of the movable block 1004 is connected to the buffer spring 1006. The upper end of the buffer spring 1006 is provided with a damper, which can effectively slow down the downward impact speed of the locking rod 301 and ensure that the device is not damaged.

[0039] Motor 11 is covered by rotating platform 5, and motor 11 and drive shaft 12 are in a rotating structure. A ratchet 13 is provided on the outside of drive shaft 12. The diameter of ratchet 13 is smaller than the length of dust cover 4. Dust cover 4 is provided with a track for rotating platform 5. Rotating platform 5 is cylindrical, so that the device can rotate horizontally and move horizontally.

[0040] The ratchet 13 is equipped with a self-locking structure 14 in each of the four directions: front, back, left, and right. The self-locking structure 14 includes a thorn 1401, an eccentric shaft 1402, a moving shaft 1403, an electric telescopic rod 1404, and a compression spring 1405. The thorn 1401 can engage with the ratchet 13, and the thorn 1401 rotates around the eccentric shaft 1402. The moving shaft 1403 is connected to the electric telescopic rod 1404, which can ensure that the rotation can be stopped suddenly, thus improving the safety of use.

[0041] The main body 6 of the device is equipped with a lifting device 16, which includes a second motor 1601, a drum 1602, a steel cable 1603 and a hook 1604. The steel cable 1603 and the hook 1604 are integrated. The steel cable 1603 is connected to the drum 1602 through multiple pulleys. The drum 1602 and the second motor 1601 are in a rotating structure, which ensures that the basic functions of the lifting device can be used normally and that the operation is smooth.

[0042] Working principle: When using the intelligent lifting device installed on the ship's deck machinery, the operator first needs to fix the fixing plate 101 to the deck using the connecting bolts 2. Then, the machine is used to align the locking rod 301 at the bottom of the connecting plate 3 with the four mounting cylinders 7. The locking rod 301 is then lowered, fully engaging within the mounting cylinders 7, completing the initial engagement. The mounting cylinders 7 are equipped with a locking mechanism 8. When the locking rod 301 contacts the T-shaped rod 801, it causes the T-shaped rod 801 to be squeezed and move to the right. At this time, a small motor inside the recovery device 9 drives the main shaft 903, causing both winding reels 901 and 902 to rotate. The winding connection method on the winding reel 902 is reversed, so winding work will be performed on both. At this time, the left T-shaped rod 801 will move to the right and the right T-shaped rod 801 will move to the left, thus stretching the compression spring 802. The dual power pushes the T-shaped rod 801 to move. When the locking rod 301 continues to descend, it will align the reserved slot with the T-shaped rod 801. At this time, the motor stops rotating, and the compression spring 802 will no longer have tension, which will drive the left T-shaped rod 801 to the right to lock into the slot of the locking rod 301. The right side moves in the opposite direction, thus completing the secondary locking work. The double locking is more stable. When operating on a ship, swaying is inevitable. When the main body 6 of the device shakes, the connecting plate 3 and the locking rod 301 will shake up and down together. The locking rod 301 will squeeze The compression block 1001 is pressed down, causing it to descend. The compression block 1001 is connected to the movable block 1004 via a connecting rod 1002, with a central shaft 1003 in the middle of the connecting rod 1002. When one end of the connecting rod 1002 descends with the compression block 1001, the other end of the connecting rod 1002, along with the movable block 1004, moves upward in the direction of the sliding rod 1005, thus compressing the buffer spring 1006. This slows down the downward impact speed of the locking rod 301, allowing the buffer spring 1006 to store energy. When the shaking disappears, the damper on the buffer spring 1006 releases energy, pushing the movable block 1004 back to its original position. The movable block 1004, through the connecting rod 1002, then drives the compression block 1001 back to its original position, thus completing the device... It can automatically reset. When the recovery device 9 needs to rotate horizontally, motor 11 is started first. Motor 11 drives the drive shaft 12 to rotate, and drive shaft 12 drives the ratchet 13 to rotate. A rotating platform 5 is set on the upper end of the ratchet 13. The rotating platform 5 is connected to the device body 6, so that the device body 6 starts to rotate. In the initial state, the electric telescopic rod 1404 is retracted to its shortest length to ensure that the thorn 1401 will not obstruct the rotation of the ratchet 13. When the rotation speed of the device body 6 is too high and an emergency stop is needed, the electric telescopic rod 1404 is started. The electric telescopic rod 1404 extends and pushes the moving shaft 1403 of the thorn 1401 forward, so that the thorn 1401 rotates around the eccentric shaft 1402. When the thorn 1401 is just caught on the ratchet 13,Four spikes 1401 simultaneously jam the ratchet 13, restricting its rotation. The ratchet 13 stops, achieving a self-locking emergency stop effect and preventing the rotation speed from becoming excessively high. When the lifting device needs to be started, the control device 15 starts the motor 1601, driving the drum 1602 to rotate. A steel cable 1603 is wound around the drum 1602. The height of the item on the hook 1604 is increased by retracting the steel cable 1603. Content not described in detail in this specification is prior art known to those skilled in the art.

[0043] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
