A hydraulic lift mainly realizes the lifting function through the pressure transmission of hydraulic oil. Its scissor mechanical structure makes the lift have high stability during lifting. The wide working platform and high load-bearing capacity enable a larger range of high-altitude operations and are suitable for multiple people to work simultaneously. Generally, the lifting method is adopted for loading and unloading.

[0003] Meanwhile, a corner connector for a container with a publication (announcement) number of CN222062950U includes a body provided with a first through hole and a locking device installed on the body. Among them, the locking device includes a locking tongue and a locking block. A shaft is provided on the locking block. The locking tongue and the locking block are located on opposite sides of the body in the thickness direction of the body and can be connected by a shaft passing through the first through hole. And among them, the body is provided with opposite first ear plates and second ear plates along its height direction. The first ear plate is provided with a first connection hole, the second ear plate is provided with a second connection hole, and the first connection hole and the second connection hole are arranged opposite to each other;

[0004] During the use of the above-mentioned corner connector for a container, the lifting operation of the container can be carried out at an unstable position. However, during hoisting, the bottom of some containers directly contacts the ground surface, and there is no space for the hydraulic lift to be inserted and lifted. Therefore, when installing the corner connection structure of the container or performing the lifting operation, other tools are needed to lift the container, which affects the lifting convenience of the container.

A hook 12 is fixed to the bottom end of the mobile rack 10, and the added hook 12 is convenient for hanging the container.

[0030] Furthermore, in this embodiment, a footrest 2 is fixedly provided on the right side of the frame 1, and a guide wheel is provided at the end of the footrest 2. The added guide wheel structure facilitates the movement of the frame 1.

[0031] A universal wheel 3 is rotatably provided on the left side of the bottom end of the frame 1, and the movement of the universal wheel 3 is more convenient.

[0032] A sliding frame 9 slidably arranged with the frame 1 is fixedly provided on the left side of the guiding arm 71. A guide groove is provided on the side surface of the frame 1. Wheels are provided inside the sliding frame 9 and can be positioned inside the guide groove, which can reduce friction during movement and guide the movement of the sliding frame 9.

[0033] A damping rod 73 is fixedly provided at the top end of the plug board 72. A positioning block 75 is fixedly provided at the top end of the damping rod 73. A spring 74 fitting with the plug board 72 is sleeved outside the damping rod 73. The spring 74 pushes the positioning block 75 at the top end of the damping rod 73 to be inserted into the inside of the guiding arm 71 for positioning. The slot 8 of the guiding arm 71 is L-shaped.

[0034] A motor 77 is fixedly provided on the front side of the support plate 76. A belt pulley 78 rotatable with the support plate 76 is fixedly provided at the end of the main shaft of the motor 77. The motor 77 drives the belt pulley 78 to quickly push the container.

[0035] A hook 12 is fixedly provided at the bottom end of the moving frame 10. A positioning pin 13 is inserted at the center position of the bottom end of the moving frame 10, and the positioning pin 13 is inserted with the belt pulley 78. The added positioning pin 13 can position the moving frame 10 and the belt pulley 78 and drive the hook 12 to move synchronously.

[0036] Side grooves 14 are provided on both sides of the surface of the support plate 76. Pulleys 11 rotatable with the moving frame 10 are slidably arranged inside the side grooves 14. The moving frame 10 can be guided and moved inside the side grooves 14 through the pulley 11 structure to drive the container to move to different positions.

[0037] Among them, the motor 77 and the hydraulic column 4 are both prior arts and will not be elaborated here; at the same time, the present utility model also includes a power supply, a controller, a switch, etc., which are not the main technical points of this patent and will not be elaborated here. The wiring diagram of the motor in the present utility model belongs to the common knowledge in the field, and its working principle is already a known technology. Its model is selected according to actual use, so the control method and wiring layout of the motor will not be explained in detail.

[0038] The working principle and process of the hydraulic-driven lift for rapid loading and unloading of containers:

[0039] Use the universal wheel 3 on the left side of the bottom end of the rack 1 and the guide wheel at the end of the right leg 2 to move the lift to the container loading and unloading position. Adjust the direction of the equipment through the universal wheel 3 so that the quick loading and unloading component 7 is aligned with the container. Then lock the universal wheel 3 and the guide wheel to ensure the stability of the equipment. Low-position insertion mode: If it is necessary to insert the support plate 76 into the bottom of the container, insert the insertion plate 72 into the slot 8 below the guide arm 71. At this time, the positioning block 75 at the top of the damping rod 73 is limited by the slot 8, the spring 74 is in a natural state, and the support plate 76 is in a low position, which is convenient for the staff to push it into the preset support hole position at the bottom of the container. If it is necessary to lift the container, pull out the insertion plate 72 and insert it into the upper slot 8. The insertion plate 72 drives the damping rod 73 and the positioning block 75 to move upward, and the spring 74 is compressed, so that the support plate 76 is lifted to a high position, which is convenient for docking with the lifting hole at the top of the container.

[0040] Start the hydraulic column 4. The output end of the hydraulic column 4 pushes the ratchets 5 on both sides to rotate. The ratchets 5 are engaged with the hinges 6 fixed on the rack 1. As the ratchets 5 rotate, the hinges 6 are pulled and extended, driving the guide arm 71 to slide upward along the guide groove on the side of the rack 1. The sliding frame 9 is fixed to the guide arm 71 to ensure the stable lifting and lowering of the guide arm 71, realizing the vertical lifting or lowering of the container. The moving frame 10 slides in the side groove 14 on the surface of the support plate 76 through the pulley 11 to adjust the position of the hook 12 so that it is aligned with the lifting hole or the bottom sling of the container. Move the motor 77 on the front side of the moving support plate 76. The main shaft of the motor 77 drives the belt pulley 78 to rotate. Insert the positioning pin 13 at the bottom end of the moving frame 10 into the belt pulley 78 to lock the moving frame 10 and the belt pulley 78, preventing the hook 12 from shifting during the loading and unloading process. After the hook 12 hooks the container, control the lift through the hydraulic column 4 to lift the container to the specified height.

[0041] Move the lifted container above the transport vehicle or the storage position, and slowly lower it through the hydraulic column 4 to accurately place the container. After the loading and unloading are completed, operate the hydraulic column 4 in reverse to reset the lift, pull out the positioning pin 13, the moving frame 10 returns to its original position, the insertion plate 72 is adjusted back to the initial position, and prepare for the next loading and unloading operation.

[0042] It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the term "including", "comprising" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not expressly listed, or also includes elements inherent to such process, method, article or device.

[0043] Although embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
