Description

Technical Field

[0001] The utility model relates to the technical field of underwater operations, and particularly relates to an automatic sling device for deployment. Background Art

[0002] With the development of production and the progress of technology, in the application of hoisting equipment, the requirement for the degree of automation is increasing day by day. Especially in the occasions where heavy weights need to be lifted, the operating environment is complex or the position is high, traditional hoisting operations mostly rely on manual hook-on and hook-off. This not only makes the operation complex, time-consuming and laborious, but also cannot achieve simultaneous hook-on and hook-off.

[0003] For example, in the patent document with the patent application number CN202211469272.7 and the publication date of March 21, 2023, a sling for hoisting an underwater vehicle and its using method are disclosed. It includes a balance beam and at least a pair of hoisting components arranged on the balance beam. The two hoisting components in at least a pair of the hoisting components are symmetrically arranged with respect to the center of the balance beam; the hoisting component includes a hoisting rod, an elastic stretching member and a first telescopic element; wherein, one end of the hoisting rod is hinged to the balance beam, and the other end extends downward and is fixedly connected with a hook for connecting with a lifting lug on the vehicle; the elastic stretching member is located inside the connection between the hoisting rod and the balance beam, one end of the elastic stretching member is fixedly connected with the balance beam, and the other end is fixedly connected with the hoisting rod; the fixed end of the first telescopic element is fixedly connected with the balance beam, and its telescopic end is used to horizontally support the hoisting rod. The present invention can remotely control the sling to automatically unhook and hook with the underwater vehicle, avoiding the problems of being time-consuming, laborious and having personnel safety risks caused by manual disassembly and assembly.

[0004] In the above literature, by respectively arranging a hoisting component at the four corners of the balance beam and controlling the abutting rod in the hoisting component to control hook-on and hook-off, it is necessary to control the motors at the four corners to drive the abutting rod to swing to realize rotational unhooking. However, it is necessary to ensure that the four motors are synchronously driven, otherwise the sling will move unstably or inaccurately during unhooking. Summary of the Invention

[0005] The utility model provides an automatic sling device for deployment, which simultaneously controls the hook-on and hook-off of the lifting sockets at the four corners of the balance beam by setting a movable sleeve and a hook-off device in cooperation, with simple operation, convenient use and long service life.

[0006] To achieve the above object, the technical solution of the present utility model is: an automatic sling, including a sling mechanism, a connecting rod mechanism and a jacking mechanism. The sling mechanism includes a balance beam, a lifting socket and a sling release device. The balance beam is provided with a mounting hole, and a lifting socket is fixedly arranged in the mounting hole. The connecting rod mechanism includes a horizontal connecting rod and a movable sleeve. Both sides of the horizontal connecting rod are fixedly connected to the movable sleeve. The jacking mechanism is fixedly connected to the connecting rod mechanism. The upper end of the sling release device abuts against the movable sleeve. The jacking mechanism drives the connecting mechanism to move up and down. The lower end of the sling release device is hinged to the locking tongue on the lifting socket.

[0007] With the above settings, when the jacking mechanism pushes the connecting rod mechanism to move upward, the horizontal connecting rod in the connecting rod mechanism follows, the horizontal connecting rod drives the movable sleeve to move, the movable sleeve is slidably connected to the sling release device, the movement of the movable sleeve and the movable sleeve abuts against the upper end of the sling release device, so that the upper end of the sling release device is forced to expand inward, so that the lower end of the sling release device expands outward, so that the locking tongue on the lifting socket disengages from the lifted object, so that the hook-on and hook-off of the lifting socket can be controlled, and the lifting socket can be controlled through the cooperation of the jacking mechanism and the connecting rod mechanism. The structure is simple, the transmission efficiency is high, and the service life is long.

[0008] Further, convex edges are provided around the top of the movable sleeve, and the convex edges abut against the balance beam.

[0009] With the above settings, through the setting of the convex edges, the bearing capacity at the fixed connection between the movable sleeve and the connecting rod can be reduced. The abutting area between the convex edges and the balance beam can be used as a buffer area to absorb and disperse the vibration energy, preventing the displacement of the movable sleeve under dynamic or static loads, thereby protecting the stability of the entire structure.

[0010] Further, a convex platform protruding from the bottom of the movable sleeve towards the sling release device is provided. A through hole is formed in the middle of the convex platform. The upper end of the sling release device passes through the through hole and is arranged in the movable sleeve, and the convex platform abuts against the upper end of the sling release device.

[0011] With the above settings, by setting the convex platform, the movable sleeve can move on the sling release device and the movable sleeve can abut against the sling release device.

[0012] Further, the sling release device includes a transmission cylinder. The transmission cylinder is a hollow cylindrical structure, and the upper end of the transmission cylinder is inclined upward and outward. The lower end of the transmission cylinder is hinged to the other end of the locking tongue.

[0013] With the above settings, by setting the side of the transmission cylinder close to the movable sleeve to be inclined upward and outward, the displacement of the movable sleeve is amplified by the inclined transmission cylinder, and the cooperation between the convex platform and the transmission cylinder can more effectively transmit the force to the locking tongue.

[0014] Further, the lifting socket includes a socket body and a docking sleeve. Two oppositely-positioned docking sleeves are embedded inside the side wall of the socket body. The docking sleeve includes a docking sleeve body, a locking tongue, a return spring, and a fixing plate. A first mounting hole is provided on the docking sleeve body. One end of the locking tongue extends into the return spring and protrudes from the first mounting hole. The other end of the locking tongue is arranged on the first mounting hole through the fixing plate. A connecting hole is provided on one side of the locking tongue where it protrudes from the fixing plate, and the connecting hole is hinged to the lower end of the lifting-off device.

[0015] With the above settings, by embedding the docking sleeve in the socket body, the locking tongue of the docking sleeve can firmly lock the plug, ensuring that the plug correctly enters the lifting socket, avoiding incorrect connection or incomplete insertion, thereby improving the stability of the connection. The other end of the locking tongue abuts against the fixing plate, enhancing the stability of the locking tongue and preventing it from breaking under external force. The design that the locking tongue extends into the return spring and protrudes from the fixing plate allows the locking tongue to be moved through simple operations, easily completing locking and unlocking. The connecting hole on the locking tongue can be connected to the lifting-off device, and the movement of the connecting rod is used to control the action of the locking tongue. The connecting rod can move the operation position from the locking tongue to a more convenient place, greatly improving the convenience of operation.

[0016] Further, the lifting socket further includes a guide rod. One side of the guide rod is fixedly connected to the socket body, and the other side of the guide rod is fixedly connected to the lower end of the transmission cylinder, and the connection between the other side of the guide rod and the transmission cylinder is located between the upper end and the lower end of the transmission cylinder.

[0017] With the above settings, the guide rod ensures that the transmission cylinder moves along a predetermined path. The guide rod provides stable support for the transmission rod, effectively reducing vibration during movement and improving overall stability.

[0018] Further, one side of the return spring abuts against the locking tongue, and the other side of the return spring abuts against the fixing plate.

[0019] With the above settings, when the external force disappears, there is no need to re-lock. The return spring can automatically push the locking tongue back to its original position to achieve self-locking. This automatic reset function ensures that the device can return to its original position after each operation, greatly simplifying the operation process.

[0020] Further, the balance beam is of a cuboid structure. An eyebolt is provided above the middle of the balance beam, and mounting holes are provided at the four corners of the balance beam.

[0021] With the above settings, the eyebolt above the middle provides a connection point for the sling. Through the eyebolt, the sling can be firmly connected to the balance beam, making the lifting operation more convenient and flexible. Mounting holes are provided at the four corners of the balance beam, and lifting sockets are installed at the four corners. The lifting sockets at the four corners can effectively disperse the stress points, avoid excessive stress at a single point, and reduce the risk of deformation and damage to the equipment during lifting.

[0022] Further, the transverse connecting rod includes a first transverse connecting rod and a second transverse connecting rod. The first transverse connecting rod and the second transverse connecting rod are horizontally spaced along the length direction. The connecting rod mechanism further includes a longitudinal connecting rod, and the longitudinal connecting rod is fixedly connected along the length center direction of the first transverse connecting rod and the second transverse connecting rod.

[0023] With the above arrangement, the addition of the longitudinal connecting rod provides additional support for the first transverse connecting rod and the second transverse connecting rod, enhancing the strength of the entire connecting rod mechanism, reducing local stress, and enabling the force to be evenly distributed on the connecting rod mechanism.

[0024] Further, a connecting rod mechanism is provided directly above the balance beam, and the balance beam mounting hole, the transmission cylinder, the socket body, and the movable sleeve are coaxially arranged; the jacking mechanism includes a motor and a jacking rod, and the output end of the motor is fixedly connected to the jacking rod.

[0025] With the above arrangement, the lifting socket and the sleeve are coaxially arranged, ensuring the movement trajectory, reducing the bending moment generated due to eccentric force, reducing the friction between components during the lifting process, thereby reducing wear and extending the service life; the motor drives the jacking rod to move up and down.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0031] The present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0032] As Figures 1 to 4As shown in the figure, an automatic sling includes a sling mechanism 1, a connecting rod mechanism 4, and a jacking mechanism 3. The sling mechanism 1 includes a balance beam 12, a lifting socket 2, and a sling release device 21. The upper end of the sling release device 21 abuts against a movable sleeve 5, and the lower end of the sling release device 21 is hinged to a locking tongue 26 on the lifting socket 2. The balance beam 12 is provided with a mounting hole 13, and the mounting hole 13 is fixedly connected to the lifting socket 2. The connecting rod mechanism 4 includes a horizontal connecting rod 41 and a movable sleeve 5. Both sides of the horizontal connecting rod 41 are fixedly connected to the movable sleeve 5, and the movable sleeve 5 is slidably connected to the lifting socket 2. The jacking mechanism 3 is fixedly connected to the upper end of the connecting rod mechanism 4. By driving the connecting rod mechanism 4 to move upward through the jacking mechanism 3, the connecting rod mechanism drives the movable sleeve 5 to slide on the upper end of the sling release device 21, and the locking tongue at the lower end of the sling release device 21 moves outward to achieve sling release. The structure is simple, the transmission efficiency is high, and the service life is long.

[0033] As Figure 1 shown, the balance beam 12 is of a rectangular structure. Mounting holes 13 are provided at the four corners of the balance beam 12, and the lifting sockets 2 are installed in the mounting holes 13 at the four corners. That is, there are four lifting sockets 2 on the balance beam 12, and the four lifting sockets 2 are slidably connected to the four movable sleeves 5. The lifting sockets 2 at the four corners can effectively disperse the stress points, and the hooking and unhooking of the lifting sockets can be controlled through the movable sleeves 5.

[0034] A connecting rod mechanism 4 is arranged above the balance beam 12. The horizontal connecting rod 41 includes a first horizontal connecting rod 411 and a second horizontal connecting rod 412. The first horizontal connecting rod 411 and the second horizontal connecting rod 412 are horizontally spaced along the length direction. The connecting rod mechanism 4 further includes a vertical connecting rod 43. Both ends of the vertical connecting rod 43 are fixedly connected to the centers in the length direction of the first horizontal connecting rod 411 and the second horizontal connecting rod 412 respectively. The addition of the vertical connecting rod 43 provides additional support for the first horizontal connecting rod 411 and the second horizontal connecting rod 412, enhancing the strength of the entire connecting rod mechanism 4, reducing local stress, and making the force evenly distributed on the connecting rod mechanism 4.

[0035] The balance beam 12, the mounting hole 13, the sling release device 21, and the movable sleeve 5 are coaxially arranged. The sling release device 21 and the movable sleeve 5 are coaxially arranged, ensuring the movement trajectory, reducing the bending moment generated by eccentric force, reducing the friction between components during the hoisting process, thereby reducing wear and extending the service life.

[0036] As Figure 2 shown, an eyebolt 11 is arranged above the middle of the balance beam 12, providing a connection point for the sling through the eyebolt 11 above the middle. Through the eyebolt 11, the sling can be stably connected to the balance beam 12, making the hoisting operation more convenient and flexible.

[0037] The lifting mechanism 3 is located at the center of the balance beam 12 and is fixedly connected to the link mechanism 4. The lifting mechanism 3 includes a motor 32 and a lifting rod 31. The output end of the motor 32 is fixedly connected to the lifting rod 31, so as to drive the lifting rod 31 to move through the motor 32.

[0038] As Figure 3 shown, convex edges 51 are provided on both sides of the top of the movable sleeve 5. The convex edges 51 are abutted against the balance beam 12. A convex platform 52 extending towards the lifting-off device 21 is provided at the bottom of the movable sleeve 5. By providing the convex edges 51, the bearing capacity at the fixed connection between the movable sleeve 5 and the link can be reduced. The abutting area between the convex edges 51 and the balance beam 12 can serve as a buffer area to absorb and disperse vibration energy, preventing the movable sleeve 5 from shifting under dynamic or static loads, thereby protecting the stability of the entire structure.

[0039] As Figure 3 shown, the lifting socket 2 includes a socket body 22 and a docking ferrule. Two oppositely-positioned docking ferrules are embedded inside the side wall of the socket body 22. The docking ferrule includes a docking ferrule body 28, a locking tongue 26, a return spring 25, and a fixing plate 27. A first mounting hole 281 is provided on the docking ferrule body 28. One end of the locking tongue 26 extends into the return spring 25 and protrudes from the first mounting hole 281. The other end of the locking tongue 26 is arranged on the first mounting hole 281 through the fixing plate 27. A connection hole 24 is provided on the side of the locking tongue 26 protruding from the fixing plate 27. In this embodiment, a limiting plate 261 is provided at the other end of the locking tongue 26. The fixing plate 27 includes two plate structures. A through hole is provided on the fixing plate 27, and the through hole is formed by splicing the two plates. During installation, first, the return spring 25 is arranged at the other end of the locking tongue 26, and then the two plates are spliced to form the fixing plate 27, and the other end of the locking tongue 26 protrudes from the through hole and is limited by the limiting plate 261. In addition, the socket body 22 is fixed in the mounting hole 13 by bolts.

[0040] By embedding the docking ferrule in the socket body 22, the locking tongue 26 of the docking ferrule can firmly lock the plug, ensuring that the plug correctly enters the lifting socket 2, avoiding incorrect connection or incomplete insertion, thereby improving the connection stability. The locking tongue 26 abuts against the fixing plate 27, enhancing the stability of the locking tongue 26 and preventing it from breaking under external forces. The design that the locking tongue 26 extends into the return spring 25 and protrudes from the fixing plate 27 allows the locking tongue to be moved through a simple operation, easily completing locking and unlocking. A connection hole 24 is provided on the locking tongue 26, which can be connected to the lifting-off device. The movement of the link mechanism is used to control the action of the locking tongue 26, and the link can move the operation position from the locking tongue 26 to a more convenient place, greatly improving the operation convenience.

[0041] As Figure 4As shown, the lifting and releasing device 21 includes a transmission cylinder, which is a hollow cylinder structure, and the upper end of the transmission cylinder is inclined upward and outward. The lower end of the transmission cylinder is hinged to the other end of the locking tongue. One end of the transmission cylinder is inclined towards the inner wall of the movable sleeve 5 and abuts against the inner wall of the movable sleeve 5 and the convex platform 52. The lifting socket 2 further includes a guide rod 23. The lower end of the transmission cylinder is inclined downward and inward, and the lower end of the transmission cylinder is hinged to the connection hole 24. A guide rod 23 is provided between the lifting and releasing device 21 and the socket body 22. One side of the guide rod 23 is connected to the socket body 22, and the other side of the guide rod 23 is hinged to the lifting and releasing device 21.

[0042] The inclined transmission cylinder amplifies the displacement of the movable sleeve 5. The convex edge 52 abuts against the transmission cylinder, so that the force can be more effectively transmitted to the connection hole 24. The guide rod 23 ensures that the transmission cylinder moves along a predetermined path. The guide rod 23 provides stable support for the transmission cylinder, effectively reducing the vibration during the movement and improving the overall stability.

[0043] One side of the return spring 25 abuts against the locking tongue 26, and the other side of the return spring 25 abuts against the fixing plate 27. When the external force disappears, there is no need to relock. The return spring 25 can automatically push the locking tongue 26 back to its original position to achieve self-locking. This automatic reset function ensures that the device can return to its original position after each operation, avoiding the situation that the locking tongue 26 cannot automatically reset after the hook is released and requires manual operation again, greatly simplifying the operation process.

[0044] Working principle of the utility model: When the laying sling is needed, it is fixedly connected to the eye plate 11 on the balance beam 12 through a crane. The crane moves the laying sling to a suitable position above the equipment to be lifted. When the crane descends above the equipment, the lifting plug on the equipment is inserted into the lifting sockets at the four corners of the balance beam 12. During the insertion process of the lifting plug, the locking tongue 26 is pushed outward to move. At this time, the lifting plug completely extends into the lifting socket 2, and the locking tongue 26 locks with the lifting plug to complete the hook installation action. The crane moves the balance beam 12 to move the equipment to a suitable position. When unhooking is needed, the motor 32 on the balance beam 12 pushes the jacking rod 31 to move upward. The jacking rod 31 pushes the longitudinal connecting rod 43 to move upward, and the two transverse connecting rods 41 connected to the longitudinal connecting rod 43 also move upward. The movable sleeve 5 also moves upward accordingly. During the upward movement of the movable sleeve 5, the boss 52 inside the movable sleeve 5 abuts against the unhooking device 21. One side of the unhooking device 21 that abuts against the boss 52 of the movable sleeve 5 is pressed inward, and the side of the unhooking device 21 connected to the connection hole 24 is pulled outward to drive the locking tongue 26 to move outward, and the locking tongue 26 is separated from the lifting plug to complete the unhooking action. After the unhooking is completed, when the crane moves the balance beam 12 a short distance to ensure that it does not contact the lifting plug of the equipment, the motor 32 will drive the jacking rod 31 to fall, and the movable sleeve 5 will also fall accordingly. During the falling process of the movable sleeve 5, the unhooking device 21 returns to its original position, and the locking tongue 26 is reset by relying on the return spring 25. At this time, the laying sling completes the unhooking action. By setting the cooperation between the movable sleeve 5 and the lifting socket 2 to simultaneously control the hook installation and unhooking of the lifting sockets 2 at the four corners of the balance beam 12, simultaneous hook installation and unhooking can be achieved, with simple operation, convenient use, and long service life.
