Description

Technical Field

[0001] This application relates to the technical field of lifting devices, and in particular to a high-strength lifting device for docks. Background Technology

[0002] With the continuous growth of global trade volume, the demand for port throughput capacity is constantly increasing, and terminal equipment is also developing towards higher efficiency and diversification. A variety of goods need to be hoisted at the terminal, some of which are heavy, such as cars, requiring hoisting equipment to have high strength. The existing hoisting equipment is not strong enough, which can easily cause safety hazards.

[0003] Traditional lifting equipment booms often employ only a single rod-like or frame structure, lacking targeted reinforcement design, resulting in insufficient overall rigidity and bending resistance. During high-intensity lifting operations, especially when lifting heavy objects or using the equipment in complex conditions, the boom is prone to deformation and swaying. This not only limits the maximum lifting weight of the equipment but also significantly increases the risk of damage due to structural fatigue, and may even lead to safety accidents such as falling objects. Meanwhile, most existing winding equipment uses a single winding unit to drive the cable winding and unwinding. This structure causes significant swaying and tilting of the hook during lifting and lowering. On the one hand, this can easily cause the lifted load to deviate from its intended position, affecting operational accuracy and increasing installation difficulty. On the other hand, uneven stress at both ends of the cable will exacerbate localized wear, shorten the cable's service life, and require frequent cable replacements, increasing equipment maintenance costs and operational downtime. Utility Model Content

[0004] To increase the stability and safety of hoisting operations, this application provides a high-strength hoisting device for docks.

[0005] The high-strength lifting device for docks provided in this application adopts the following technical solution: A high-strength lifting device for docks includes a base, a support portion fixedly mounted on the upper surface of the base, a rotating portion rotatably mounted on the support portion, and a rotary hydraulic cylinder for driving the rotating portion to rotate installed in the support portion. An equipment box is fixedly mounted on the upper surface of the rotating portion, a boom is fixedly mounted on the outer side of the equipment box, a cable is mounted on the head of the boom, and a cable winding device is fixedly mounted on the head of the equipment box. A hook is mounted on the cable.

[0006] By adopting the above technical solutions, the base provides a stable support foundation for the entire device, ensuring its stability in the complex environment of the dock. The support and rotating parts, in conjunction with the rotating hydraulic cylinder, enable the device to rotate, expanding the range of lifting operations. The equipment housing houses various equipment and components, providing protection and integration. The boom is used to install cables and hooks, providing necessary structural support for lifting operations. The winding equipment enables the winding and unwinding of cables, thereby controlling the raising and lowering of the hook to complete the cargo lifting task.

[0007] Optionally, the boom frame consists of two inclined boom rods, the lower ends of which are fixed to the two sides of the equipment box respectively, and the heads of the two boom rods extend to one end and meet. A guide wheel for cable installation is provided at the meeting point of the two boom rods.

[0008] By adopting the above technical solution, the boom frame, composed of two inclined boom rods, is fixed at its lower ends to both sides of the equipment box and converges at its head. This structure resembles a triangle, providing high stability and strength. The guide wheels ensure smoother cable movement, reduce friction between the cable and the boom frame, lower cable wear, and also ensure more accurate cable trajectory, thereby improving the stability of the lifting operation.

[0009] Optionally, a number of reinforcing rods are installed between the two boom rods, with both ends of the reinforcing rods fixedly connected to the two boom rods respectively, and a number of sets of reinforcing ribs are also fixedly installed between the reinforcing rods and the boom rods.

[0010] By adopting the above technical solution, the installation of reinforcing rods and ribs creates a more stable overall structure for the boom. The reinforcing rods connect the two boom members, distributing the stress generated during hoisting and preventing structural damage caused by stress concentration. The ribs further enhance the connection strength between the reinforcing rods and the boom members, improving the load-bearing capacity of the boom and enabling it to withstand high-intensity hoisting operations.

[0011] Optionally, the winding device includes a device housing, a first winding member, a second winding member, and a drive assembly. The device housing is fixedly installed at the head of the device box. The first winding member and the second winding member are both rotatably installed in the device housing and rotate synchronously. The drive assembly is fixedly installed in the device housing and is used to drive the first winding member to rotate.

[0012] By adopting the above technical solution, the equipment housing provides a closed installation space for the first winding component, the second winding component, and the drive assembly, thus protecting the internal components. The synchronous rotation design of the first and second winding components enables synchronized winding of both ends of the cable, preventing swaying of the hook on the cable, reducing cable wear, and extending the service life of the cable and the equipment. The drive assembly provides power for the winding process, ensuring smooth winding operations.

[0013] Optionally, the equipment housing includes a bottom shell and a cover, the cover being fastened to the bottom shell, and the upper surface of the cover having a top groove for cables to pass through.

[0014] By adopting the above technical solution, the combination of the bottom shell and the cover facilitates the installation and disassembly of the equipment housing, and makes it convenient to maintain and repair the internal components. The top slot provides a passage for the cable to pass through, allowing the cable to smoothly enter the equipment housing and connect with the winding mechanism, while also ensuring that the movement of the cable is not obstructed during the winding process.

[0015] Optionally, the first winding component includes a winding roller, a driven gear, and a driving gear. The winding roller is rotatably mounted in the bottom shell, and the driven gear and the driving gear are both sleeved and fixed to one end of the winding roller.

[0016] By adopting the above technical solution, the take-up roller is used to wind the cable, realizing the cable winding and unwinding function. Driven gear one and drive gear two are sleeved on one end of the take-up roller one. Through cooperation with the drive assembly and the second take-up member, power transmission and rotation of the take-up roller one are realized, thereby driving the cable winding. In actual use, this allows the first take-up member to accurately complete the cable winding task.

[0017] Optionally, the second winding component includes a second winding roller and a second driven gear that meshes with a second drive gear. The second winding roller is rotatably mounted in the bottom shell, and the second driven gear is sleeved and fixed to one end of the second winding roller.

[0018] By adopting the above technical solution, the second winding roller works in conjunction with the first winding roller to synchronously wind up the cable. The driven gear second meshes with the driving gear second, enabling the second winding roller to rotate synchronously with the first winding roller, ensuring synchronous movement at both ends of the cable, avoiding swaying of the hook and wear of the cable, and improving the stability of the hoisting operation and the service life of the equipment.

[0019] Optionally, the drive assembly includes a servo motor with a brake and a drive gear that meshes with a driven gear. The servo motor is fixedly mounted in the bottom housing, and the drive gear is fixedly mounted on the output shaft of the servo motor.

[0020] By adopting the above technical solution, the servo motor with brake possesses precise control performance, enabling adjustment of the winding speed and stop position according to actual needs. A drive gear is mounted on the output shaft of the servo motor and meshes with the driven gear, transmitting the power of the servo motor to the first winding component, thereby driving the entire winding process. The braking function ensures that the winding equipment can be locked in time when the lifting operation stops, preventing the hook and cargo from moving due to inertia, thus improving the safety of the lifting operation.

[0021] In summary, this application includes at least one of the following beneficial technical effects: The boom frame of this application adopts a structural design of inclined boom rods, reinforcing rods, and reinforcing ribs, which greatly improves the load-bearing capacity and stability of the boom frame, enabling it to adapt to high-intensity lifting operations and reducing the risk of damage during equipment use. The winding device adopts a design of synchronous rotation of the first and second winding components, realizing synchronous winding of both ends of the cable, avoiding hook swaying and cable wear, extending the service life of the cable and equipment, and improving the stability of lifting operations. At the same time, by using a servo motor with a brake in the drive component, the winding speed and stopping position can be precisely controlled. The braking function ensures the stability of the equipment when the lifting operation stops, improving the safety of the lifting operation. The setting of the support and rotating parts, in conjunction with the rotating hydraulic cylinder, enables the device to realize the rotation function, expanding the lifting operation range and improving the efficiency of equipment use.

[0027] The present application will be further described in detail below with reference to the accompanying drawings.

[0028] This application discloses a high-strength lifting device for docks. (Refer to...) Figure 1 , Figure 2 and Figure 3 A high-strength lifting device for docks includes a base, a support part 1 fixedly mounted on the upper surface of the base, a rotating part 2 rotatably mounted on the support part 1, and a rotary hydraulic cylinder for driving the rotating part 2 to rotate installed in the support part 1. An equipment box 3 is fixedly mounted on the upper surface of the rotating part 2, and a boom 4 is fixedly mounted on the outer side of the equipment box 3. A cable 5 is mounted on the head of the boom 4, and a winding device 6 for winding the cable 5 is fixedly mounted on the head of the equipment box 3. A hook 7 is mounted on the winding cable 5. The base provides a stable support foundation for the entire device, ensuring its stability in the complex environment of the dock. The arrangement of the support part 1 and the rotating part 2, in conjunction with the rotary hydraulic cylinder, enables the device to achieve rotation, expanding the range of lifting operations. The equipment box 3 is used to install various equipment and components, serving a protective and integrated function. The boom 4 is used to install the cable 5 and the hook 7, providing necessary structural support for lifting operations. The winding device 6 can wind up and unwind the cable 5, thereby controlling the lifting and lowering of the hook 7 to complete the lifting task of the goods.

[0029] Reference Figure 1 The boom 4 consists of two inclined boom rods, the lower ends of which are fixed to both sides of the equipment box 3, and the heads of the two boom rods extend towards one end and converge. A guide wheel for installing the cable 5 is provided at the convergence point of the two boom rods. The boom 4, composed of two inclined boom rods, with its lower ends fixed to both sides of the equipment box 3 and its heads converging, has a triangular structure, providing high stability and strength. The guide wheel ensures smoother movement of the cable 5, reducing friction between the cable 5 and the boom 4, minimizing wear on the cable 5, and ensuring a more accurate movement trajectory, thus improving the stability of the lifting operation. Several reinforcing rods 41 are installed between the two boom rods, with both ends of the reinforcing rods 41 fixedly connected to the two boom rods. Several sets of reinforcing ribs are also fixedly installed between the reinforcing rods 41 and the boom rods. The installation of the reinforcing rods 41 and the reinforcing ribs makes the boom 4 form a more stable overall structure. The reinforcing rod 41 connects the two boom rods, dispersing the stress generated during hoisting and preventing structural damage caused by stress concentration. The reinforcing rib further enhances the connection strength between the reinforcing rod 41 and the boom rod, improving the load-bearing capacity of the boom frame 4 and enabling it to adapt to high-intensity hoisting operations.

The drive assembly 64 is fixedly installed within the housing 61 and is used to drive the first winding member 62 to rotate. The housing 61 provides a closed installation space for the first winding member 62, the second winding member 63, and the drive assembly 64, protecting the internal components. The synchronous rotation design of the first winding member 62 and the second winding member 63 enables synchronous winding of both ends of the cable 5, avoiding swaying of the hook 7 on the cable 5, reducing wear on the cable 5, and extending the service life of the cable 5 and the device. The drive assembly 64 provides power for the winding process, ensuring smooth winding operations. The equipment housing 61 includes a bottom shell 611 and a cover 612. The cover 612 is fastened to the bottom shell 611, and the upper surface of the cover 612 is provided with a top groove 613 for the cable 5 to pass through. The combination of the bottom shell 611 and the cover 612 facilitates the installation and disassembly of the equipment housing 61 and makes it convenient for maintenance and repair of the internal components. The top groove 613 provides a channel for the cable 5 to pass through, allowing the cable 5 to smoothly enter the interior of the equipment housing 61 and connect with the winding component, while also ensuring that the movement of the cable 5 is not obstructed during the winding process.

[0031] Reference Figure 2 , Figure 3 and Figure 4 The first winding component 62 includes a winding roller 621, a driven gear 622, and a drive gear 623. The winding roller 621 is rotatably mounted in the base shell 611. The driven gear 622 and the drive gear 623 are both sleeved and fixed to one end of the winding roller 621. The winding roller 621 is used to wind the cable 5, realizing the winding and unwinding function of the cable 5. The driven gear 622 and the drive gear 623 are sleeved on one end of the winding roller 621. Through cooperation with the drive assembly 64 and the second winding component 63, the power transmission and rotation of the winding roller 621 are realized, thereby driving the winding of the cable 5. In actual use, this allows the first winding component 62 to accurately complete the winding task of the cable 5. The second winding component 63 includes a second winding roller 631 and a driven gear 632 meshing with a second drive gear 623. The second winding roller 631 is rotatably mounted in the base shell 611, and the driven gear 632 is sleeved and fixed to one end of the second winding roller 631. The second winding roller 631 cooperates with the first winding roller 621 to synchronously wind up the cable 5. The driven gear 632 meshes with the second drive gear 623, enabling the second winding roller 631 to rotate synchronously with the first winding roller 621, ensuring synchronous movement of both ends of the cable 5, avoiding swaying of the hook 7 and wear of the cable 5, improving the stability of the lifting operation and the service life of the equipment.

[0032] Reference Figure 2 , Figure 3 and Figure 4 The drive assembly 64 includes a servo motor 641 with a brake and a drive gear 642 meshing with a driven gear 622. The servo motor 641 is fixedly mounted in the base housing 611, and the drive gear 642 is sleeved and fixed on the output shaft of the servo motor 641. The servo motor 641 with a brake has precise control performance and can adjust the winding speed and stop position according to actual needs. The drive gear 642 is sleeved on the output shaft of the servo motor 641 and meshes with the driven gear 622, transmitting the power of the servo motor 641 to the first winding component 62, thereby driving the entire winding process. The braking function ensures that the winding device 6 can be locked in time when the lifting operation stops, preventing the hook 7 and the cargo from moving due to inertia, thus improving the safety of the lifting operation.

[0033] The implementation principle of a high-strength lifting device for docks according to this application embodiment is as follows: In actual use, the item to be lifted is suspended on the hook 7. The servo motor 641 with brake is started. The servo motor 641 drives the driven gear 622 to rotate via the drive gear 642, which in turn drives the winding roller 621 to rotate. Since the winding roller 621 and the winding roller 631 are connected via the drive gear 623 and the driven gear 632, the winding rollers 621 and 631 rotate synchronously, achieving synchronous winding of both ends of the cable 5. The hook 7 then rises, completing the lifting of the goods. During the lifting process, if it is necessary to adjust the lifting position, the rotating part 2 can be driven to rotate by controlling the rotary hydraulic cylinder, thus rotating the device. After the lifting operation is completed, the servo motor 641 is stopped, the brake function is activated, and the winding device 6 is locked to prevent the hook 7 and the goods from moving.

[0034] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
