Description
Technical Field
[0001] This utility model relates to the field of hoisting device technology, specifically a fully automatic hoisting device for a ship unloader. Background Technology
[0002] The fully automatic lifting device for ship unloaders belongs to the field of ship unloader lifting equipment. It is mainly used in unloading operations in ports, docks and other places to realize the lifting and transfer of goods from ships to shore or designated areas. It is an important component of ship unloaders to achieve efficient loading and unloading of goods and directly affects the efficiency and safety of unloading operations.
[0003] In existing ship unloader hoisting structures, the coordination between the support structure and the lateral connection structure is poor, making it difficult to flexibly adjust the hoisting height and horizontal position. Furthermore, the lack of a stable core load-bearing structure results in insufficient overall stability after the installation of each functional component. The winch installation structure suffers from poor stability, easily swaying during high-speed operation or under heavy loads, affecting hoisting accuracy and safety. Simultaneously, existing anti-sway structures have limited effectiveness in suppressing hook swaying, failing to address the root cause of the problem. While some structures incorporate cable guide components, their guiding effect is poor, leading to cable misalignment and hook position shift. The cables are also prone to sagging due to their own weight, and the guide components themselves lack structural strength, easily deforming under cable tension. Utility Model Content
[0004] To address the shortcomings of existing technologies, this utility model provides a fully automatic hoisting device for ship unloaders, which solves the technical problems of poor guiding effect, easy displacement of steel cables leading to hook position movement, easy sag of steel cables due to their own weight, and insufficient structural strength of the guiding components, which are prone to deformation under the tension of steel cables.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a fully automatic hoisting device for a ship unloader, comprising: a support arm and a horizontal connecting arm, wherein the horizontal connecting arm is connected to the support arm, and the two work together to flexibly adjust the hoisting height and horizontal position, providing basic support for subsequent precise hoisting of workpieces; the output end of the horizontal connecting arm is connected to an assembly frame, which serves as the core load-bearing structure and provides a stable installation platform for subsequent functional components; a support frame is provided at the bottom of the assembly frame, which enhances the stability of the winch after installation and prevents the winch from shaking during high-speed operation or under load; a winch is provided outside the support frame, and a hook is connected to the output end of the winch;
[0006] The workpiece is hoisted by a hook, and the lifting and lowering of the hook is controlled by a winch. The winch can precisely adjust the lifting and lowering speed of the hook according to the hoisting requirements to achieve smooth lifting and lowering of the workpiece. The assembly frame is equipped with an anti-sway mechanism on the outside. The anti-sway mechanism is linked with the winch and the hook to suppress the swaying problem of the hook from the root.
[0007] The anti-sway mechanism includes a guide frame, which is connected to the support frame. The guide frame is connected to the assembly frame through reinforcing ribs. The reinforcing ribs can further improve the structural strength of the guide frame and prevent the guide frame from deforming under the tension of the steel cable. The steel cable of the winch is installed through the top of the guide frame. The guide frame guides the steel cable of the winch to avoid the steel cable from shifting position when it rotates outside the output shaft of the winch. This prevents the hook from shifting position due to the steel cable. At the same time, the guide frame can also provide some support for the steel cable and reduce the deviation caused by the steel cable sag due to its own weight.
[0008] The bottom of the guide frame is connected to a telescopic arm via an electric linear guide rail. The other end of the telescopic arm is rotatably connected to a reinforcing frame. The reinforcing frame can fit against the outside of the steel cable or hook to form a limit from the side. The rotatable connection design allows the reinforcing frame to be flexibly adjusted with the swing direction of the hook, always maintaining the limiting effect.
[0009] The reinforcement frame is installed between the hook and the output end of the winch. When the hook moves, the position of the reinforcement frame and the hook is restricted by the telescopic arm to prevent the hook from swaying during use. The telescopic arm can extend and retract synchronously according to the lifting height of the hook to ensure that the reinforcement frame is always within the effective limit range and improve the continuity of the anti-sway effect.
[0010] Preferably, a rotating module is provided at the top of the support arm. The output end of the rotating module is connected to the outside of the cross arm. The rotating module can drive the cross arm to rotate around the top of the support arm, achieving 360-degree lifting operation coverage and greatly improving the operational flexibility and coverage of the device.
[0011] Preferably, the horizontal arm includes a horizontal arm, and a linear motion module is provided at the bottom of the horizontal arm. The output end of the linear motion module is connected to the assembly frame. The linear motion module can drive the assembly frame to move smoothly along the length direction of the horizontal arm. Combined with the rotation function of the rotation module, it can achieve precise positioning in the horizontal direction, so that the hook can be quickly aligned with the workpiece to be lifted.
[0012] Preferably, a displacement sensor is installed at one end of the telescopic arm near the guide frame. The displacement sensor is electrically connected to the drive module of the electric linear guide. The displacement sensor can detect the telescopic arm's extension length in real time and feed the data back to the drive module. The drive module precisely adjusts the extension amount of the telescopic arm based on the feedback to ensure that the reinforcement frame accurately limits the hook position. Furthermore, the top of the guide frame has a guide hole adapted to the winch cable. The inner wall of the guide hole is coated with a wear-resistant coating. This wear-resistant coating can reduce the friction loss between the cable and the inner wall of the guide hole, extend the service life of the cable, and further ensure the stable sliding of the cable in the guide hole, assisting the guide frame in achieving precise guidance. In addition, the wear-resistant coating can also reduce the noise generated when the cable slides, improving the stability and quietness of the device during operation.
[0013] Preferably, a tension sensor is installed at the top of the hook. The tension sensor is electrically connected to the braking module of the winch and can monitor the tension of the hook when lifting the workpiece in real time. When the tension exceeds a preset threshold, the braking module of the winch is triggered to brake, avoiding damage to the hook or steel cable due to overload. The preset threshold of the tension sensor can be flexibly adjusted according to the weight of different workpieces to adapt to the lifting needs of various specifications of workpieces and improve the versatility of the device. In addition, a buffer sleeve is provided on the outside of the hook body. The buffer sleeve is made of elastic rubber and has anti-slip texture. The elastic rubber material can buffer the impact force when the hook comes into contact with the workpiece, and the anti-slip texture can enhance the friction between the hook and the workpiece, preventing the workpiece from sliding during the lifting process. This, combined with the anti-sway mechanism, improves the lifting stability. The elastic rubber buffer sleeve can also prevent the hook from scratching the surface of the workpiece. The anti-slip texture can still maintain a good anti-slip effect in wet or oily environments, further ensuring lifting safety.
[0014] Preferably, the assembly frame is provided with a protective shell on its side. The surface of the protective shell is provided with heat dissipation holes, and the bottom of the protective shell is provided with a transparent observation window. The heat dissipation holes can dissipate the heat generated by the internal components of the assembly frame during operation in a timely manner, preventing the components from being affected by high temperature. The heat dissipation holes adopt a uniform distribution design, which can quickly form air convection, improve heat dissipation efficiency, and ensure that the internal components are kept at a suitable working temperature for a long time. The transparent observation window allows the staff to observe the working status of internal components such as winches and anti-shake mechanisms in real time, making it easier to detect and deal with abnormalities in a timely manner. The transparent observation window is made of tempered glass, which has good transparency and impact resistance. It can protect the internal components while allowing the staff to clearly observe the details of the components, reducing the difficulty of troubleshooting abnormalities.
[0015] Compared with the prior art, this utility model provides a fully automatic hoisting device for ship unloaders, which has the following advantages:
[0016] This fully automatic lifting device for the ship unloader utilizes a support arm and a cross arm working in tandem to flexibly adjust the lifting height and horizontal position. The assembly frame, as the core load-bearing structure, provides a stable installation platform for all functional components. The support frame enhances the stability of the winch after installation, preventing swaying during high-speed operation or under heavy load. The anti-sway mechanism is linked with the winch and hook to suppress hook swaying at its source. The guide frame guides the winch cable, preventing cable deviation that could cause hook position movement, and also supports the cable, reducing cable slippage due to its own weight. Reinforcing ribs further enhance the structural strength of the guide frame, preventing deformation under cable tension. The telescopic arm, connected to the bottom of the guide frame via an electric linear guide rail, extends and retracts synchronously with the hook's lifting height, ensuring the rotatably connected reinforcement frame remains within its effective limit range. The reinforcement frame conforms to the outside of the cable or hook, providing lateral restraint, and its rotating design allows for flexible adjustment with the hook's swing direction, maintaining the restraint effect and continuously improving the anti-sway performance.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] This utility model provides a technical solution, please refer to Figure 1 , Figure 2 and Figure 3A fully automatic hoisting device for a ship unloader includes: a support arm 1 and a horizontal arm 2. The horizontal arm 2 is connected to the support arm 1. The two work together to flexibly adjust the hoisting height and horizontal position, providing basic support for the subsequent precise hoisting of workpieces. The output end of the horizontal arm 2 is connected to an assembly frame 3. The assembly frame 3 serves as the core load-bearing structure, providing a stable installation platform for subsequent functional components. A support frame 41 is provided at the bottom of the assembly frame 3. The support frame 41 can enhance the stability of the winch 4 after installation and prevent the winch 4 from shaking when running at high speed or under load. The winch 4 is provided on the outside of the support frame 41. The output end of the winch 4 is connected to a hook 5.
[0023] The workpiece is hoisted by the hook 5 and the lifting and lowering of the hook 5 is controlled by the winch 4. The winch 4 can precisely adjust the lifting and lowering speed of the hook 5 according to the hoisting requirements to achieve smooth lifting and lowering of the workpiece. The assembly frame 3 is equipped with an anti-sway mechanism 6 on the outside. The anti-sway mechanism 6 is linked with the winch 4 and the hook 5 to suppress the swaying problem of the hook 5 from the root.
[0024] The anti-sway mechanism 6 includes a guide frame 61, which is connected to the support frame 41. The guide frame 61 is connected to the assembly frame 3 through a reinforcing rib 62. The reinforcing rib 62 can further improve the structural strength of the guide frame 61 and prevent the guide frame 61 from deforming under the tension of the steel cable. The steel cable of the winch 4 is installed through the top of the guide frame 61. The guide frame 61 guides the steel cable of the winch 4 to avoid the steel cable from shifting position when it rotates outside the output shaft of the winch 4, thereby preventing the hook 5 from shifting position due to the steel cable shift. At the same time, the guide frame 61 can also provide a certain support for the steel cable and reduce the shift caused by the steel cable sag due to its own weight.
[0025] The bottom of the guide frame 61 is connected to the telescopic arm 63 via an electric linear guide rail. The other end of the telescopic arm 63 is rotatably connected to the reinforcing frame 64. The reinforcing frame 64 can fit against the outside of the steel cable or hook 5 to form a limit from the side. The rotatable connection design allows the reinforcing frame 64 to be flexibly adjusted with the swing direction of the hook 5, always maintaining the limiting effect.
[0026] The reinforcing frame 64 is located between the hook 5 and the output end of the winch 4. When the hook 5 is in motion, the position of the reinforcing frame 64 and the hook 5 is restricted by the telescopic arm 63 to prevent the hook 5 from swaying during use. The telescopic arm 63 can extend and retract synchronously according to the lifting height of the hook 5 to ensure that the reinforcing frame 64 is always within the effective limit range and improve the continuity of the anti-sway effect.
[0027] A rotating module 21 is provided at the top of the support arm 1. The output end of the rotating module 21 is connected to the outside of the cross arm 2. The rotating module 21 can drive the cross arm 2 to rotate around the top of the support arm 1, so as to achieve 360-degree lifting operation coverage and greatly improve the operation flexibility and coverage of the device.
[0028] The horizontal arm 2 includes a horizontal arm, and a linear motion module is provided at the bottom of the horizontal arm. The output end of the linear motion module is connected to the assembly frame 3. The linear motion module can drive the assembly frame 3 to move smoothly along the length of the horizontal arm. Combined with the rotation function of the rotation module 21, it can achieve precise positioning in the horizontal direction, so that the hook 5 can quickly align with the workpiece to be lifted.
[0029] A displacement sensor is installed at one end of the telescopic boom 63 near the guide frame 61. The displacement sensor is electrically connected to the drive module of the electric linear guide. The displacement sensor can detect the telescopic length of the telescopic boom 63 in real time and feed the data back to the drive module. The drive module adjusts the telescopic amount of the telescopic boom 63 precisely according to the feedback to ensure that the reinforcing frame 64 accurately limits the position of the hook 5. The top of the guide frame 61 has a guide hole that matches the steel cable of the winch 4. The inner wall of the guide hole is coated with a wear-resistant coating. This wear-resistant coating can reduce the friction loss between the steel cable and the inner wall of the guide hole, extend the service life of the steel cable, and further ensure the stable sliding of the steel cable in the guide hole, assisting the guide frame 61 to achieve precise guidance. In addition, the wear-resistant coating can also reduce the noise generated when the steel cable slides, and improve the stability and quietness of the device operation.
[0030] A tension sensor is installed on the top of the hook 5. The tension sensor is electrically connected to the braking module of the winch 4. It can monitor the tension of the hook 5 when lifting the workpiece in real time. When the tension exceeds the preset threshold, the braking module of the winch 4 is triggered to brake, so as to avoid damage to the hook 5 or the steel cable due to overload. The preset threshold of the tension sensor can be flexibly adjusted according to the weight of different workpieces to adapt to the lifting needs of various specifications of workpieces and improve the versatility of the device. The hook body of the hook 5 is covered with a buffer sleeve. The buffer sleeve is made of elastic rubber and has anti-slip texture. The elastic rubber material can buffer the impact force when the hook 5 contacts the workpiece, and the anti-slip texture can enhance the friction between the hook 5 and the workpiece to prevent the workpiece from sliding during the lifting process. This, together with the anti-sway mechanism 6, improves the lifting stability. The elastic rubber buffer sleeve can also prevent the hook 5 from scratching the surface of the workpiece. The anti-slip texture can still maintain a good anti-slip effect in wet or oily environments, further ensuring the lifting safety.
[0031] The side of the assembly frame 3 is equipped with a protective shell. The surface of the protective shell has heat dissipation holes, and the bottom of the protective shell is equipped with a transparent observation window. The heat dissipation holes can dissipate the heat generated by the internal components of the assembly frame 3 during operation in a timely manner, preventing the components from being affected by high temperature. The heat dissipation holes are evenly distributed, which can quickly form air convection, improve heat dissipation efficiency, and ensure that the internal components are kept at a suitable working temperature for a long time. The transparent observation window allows the staff to observe the working status of internal components such as the winch 4 and the anti-shake mechanism 6 in real time, making it easier to detect and deal with abnormalities in a timely manner. The transparent observation window is made of tempered glass, which has good transparency and impact resistance. It can protect the internal components while allowing the staff to clearly observe the details of the components, reducing the difficulty of troubleshooting abnormalities.
[0032] This solution uses hook 5 to lift the workpiece, and winch 4 to control the lifting and lowering of hook 5. At the same time, guide frame 61 guides the steel cable of winch 4 to prevent the steel cable from shifting position when it rotates outside the output shaft of winch 4, which would cause the hook 5 to move. In addition, when hook 5 moves, telescopic arm 63 restricts the position of reinforcement frame 64 and hook 5 to prevent hook 5 from swaying during use.
