Description

Technical Field

[0001] This utility model relates to the field of mechanical maintenance technology, specifically to an auxiliary lifting device for port machinery maintenance. Background Technology

[0002] In the midst of busy port operations, the stable operation of port machinery is crucial. Port machinery operates under high-intensity, complex, and ever-changing environments, such as exposure to wind and sun, seawater erosion, and frequent cargo loading and unloading operations. This makes its components prone to wear and tear and malfunctions, requiring regular maintenance and repair.

[0003] In traditional port machinery maintenance, lifting and supporting are often challenging issues when repairing or replacing damaged parts. Previously used simple lifting tools are not only laborious and inefficient, but also struggle to achieve stable and precise vertical lifting, often resulting in swaying and shifting during the lifting process. This poses a significant safety hazard for the large and complex components of port machinery. Furthermore, port machinery is diverse, with significant differences in the shape, structure, and size of its components, ranging from large, flat loading and unloading platforms to crane boom joints with specific tilt angles. However, traditional supporting equipment often lacks flexible adjustment capabilities, failing to provide suitable support angles according to the different shapes and structures of components, thus limiting its application in the maintenance of various types of port machinery.

[0004] Based on the various problems exposed in the lifting and support stages of traditional port machinery maintenance, in order to improve maintenance efficiency, ensure maintenance safety, and broaden the application scope of maintenance equipment, this utility model provides an auxiliary lifting device for port machinery maintenance, aiming to provide a more convenient, efficient, safe, and adaptable solution for port machinery maintenance work.

[0006] Preferably, the bottom end of the limiting frame is fixedly connected to the outer wall of the movable seat, the bottom end of the lifting screw is rotatably connected to the outer wall of the movable seat, the outer wall of the guide wheel is slidably connected to the outer wall of the limiting frame, and the outer wall of the lifting screw is threadedly connected to the inner wall of the support platform. The entire device is moved to the area below the machine to be repaired via the movable seat at the bottom. After the servo motor starts, power is transmitted to the lifting screw through the pulley assembly, driving the lifting screw to rotate.

[0007] Preferably, the outer wall of the servo motor is fixedly connected to the outer wall of the limiting frame, and the end of the pulley assembly away from the servo motor is fixedly connected to the top of the lifting screw. The rotating lifting screw engages with the threaded connection of the support platform, pushing the support platform to move vertically along the limiting frame. The guide wheel and the sliding frame slide within the limiting frame, ensuring a smooth and unbiased lifting process, allowing the support platform to move to below the component being repaired.

[0008] Preferably, the adjusting assembly includes an adjusting plate, a rotating rod symmetrically rotatably connected to the outer wall of the adjusting plate, a support rod rotatably connected to the outer wall of the rotating rod, a sliding block rotatably connected to the end of the rotating rod away from the adjusting plate, and an adjusting screw threadedly connected to the inner wall of the sliding block. Rotating the adjusting screw drives the sliding block to move horizontally on the support platform. Through the linkage mechanism of the rotating rod and the support rod, the adjusting plate is tilted or horizontally displaced to adapt to the support angle requirements of different maintenance components.

[0009] Preferably, the end of the support rod away from the rotating rod is rotatably connected to the outer wall of the support platform, the outer wall of the sliding block is slidably connected to the inner wall of the support platform, and the adjusting screw is rotatably connected to the outer wall of the support platform through a rotating shaft.

[0010] Preferably, the adjusting plate has a limiting hole in its wall, and a movable block is symmetrically slidably connected to the inner wall of the adjusting plate. A buffer pad is fixedly connected to the outer wall of the movable block, and an insertion rod is slidably connected to the inner wall of the movable block. The outer wall of the insertion rod is slidably connected to the inner wall of the limiting hole. The movable block can slide along the adjusting plate and is fixed in position by inserting the insertion rod into the limiting hole, accommodating components of different sizes. The buffer pad provides flexible support when in contact with the component, preventing rigid collisions from damaging the equipment.

[0011] The beneficial effects of this utility model are as follows:

[0012] 1. This utility model, by setting up a lifting device, uses a servo motor and pulley set to drive the lifting screw to rotate, which engages with the threaded connection of the support platform to achieve stable and precise vertical lifting. In addition, the self-locking characteristic of the lifting screw ensures that the lifting height can be firmly maintained after reaching the designated position. Even under long-term operation or complex working conditions, there will be no accidental descent, ensuring the personal safety of maintenance personnel and the smooth progress of maintenance operations.

[0013] 2. This utility model, by setting an adjustment component, drives the sliding block to move horizontally by rotating the adjustment screw, and then, with the help of the linkage mechanism composed of the rotating rod and the support rod, can push the adjustment plate to achieve tilting or horizontal displacement. This allows the device to adapt to port machinery maintenance parts of various shapes and structures, providing support angles for both planar parts and parts with specific angles, thus broadening the applicability of the device. Furthermore, the moving block can slide flexibly along the adjustment plate and be fixed in position by inserting the insertion rod into the limiting hole, enabling rapid adjustment according to maintenance parts of different sizes, further enhancing its practicality in port machinery maintenance.
