DETAILED DESCRIPTION

[0020] In order to make the above-mentioned objects, features and advantages of the present invention more clearly understood, the following describes in detail the specific embodiments of the present invention in conjunction with the accompanying drawings. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0021] The purpose of the utility model is to provide a container landing jack to solve the problem that the existing supporting equipment is difficult to cooperate with the lifting of the container when it is landed, resulting in difficulty in handling the container.

[0022] Since this field requires the cooperation of multiple lifting or large lifting forklifts and other equipment to complete the container handling operation, especially when the container is on the ground, the lifting operation is more difficult. The current technology requires a large site, the operation process is cumbersome, the work efficiency is low, the cost is high, and multiple operators are required to work together at the same time, which takes a long time and brings many safety hazards.

[0023] In order to solve the above problems, this embodiment provides a container floor jack, which is mainly connected with the corner piece provided at the lower end of the container. Figure 1 and 2 As shown, the jack body 100 provided in this embodiment is provided with a corner fitting connection mechanism 200 at the lower portion of the side wall, perpendicular to the height direction of the jack body 100. During installation, the outer end of the corner fitting connection mechanism 200 is mated with the corner fitting. After the jacking operation is completed, the connection between the two is released. The detachable connection method is not limited, and a snap connection or a threaded connection is preferred. The corner fitting connection mechanism 200 can be raised and lowered synchronously with the raising and lowering of the jack body 100. Once the two are connected, the container can be raised and lowered by the lifting jack. Because it is mated with the corner fitting at the bottom of the container side wall, it is not affected by the container's landing state. This solves the problems existing in the prior art, has a simple structure, and improves work efficiency.

[0024] During specific use, the jacks provided in this embodiment can be connected to the corner pieces at the bottom of two opposite sides of the container. In this way, the force is balanced during the lifting process, and the safety and stability are better.

[0025] In order to improve the connection stability between the container and the jack body 100 during the lifting process, a balancing pad 101 is set at the top of the jack body 100 in the same direction as the corner piece connection mechanism 200 to support the gap between the side wall of the container and the jack body 100. After the two are connected, the outer side of the balancing pad 101 abuts against the side wall of the container, and by increasing the friction between the two, the two are in a relatively stable state, thereby effectively preventing the container or the jack body 100 from tilting during the lifting movement.

[0026] Preferably, the jack body 100 includes a base 110 and a hydraulic cylinder body 120 on the upper portion thereof. A movable pulley 111 may be provided at the base 110 to facilitate movement of the jack body 100, greatly saving manpower during long-distance transport. A connecting joint 121 is provided at the hydraulic cylinder body 120, which can be detachably connected to a hydraulic pump. The hydraulic pump drives the jack body 100 to be raised and lowered, thereby improving work efficiency. Of course, the hydraulic pump includes a manually driven type and an electrically driven type. A suitable hydraulic pump may be provided as needed, which is not shown in the structural diagram. Those skilled in the art can understand the working principle and structure of the hydraulic pump and select a suitable hydraulic pump as needed.

[0027] In order to enhance the adaptability of this embodiment, a height adjustment mechanism 112 may be provided on the movable pulley 111 to adjust the installation height of the movable pulley 111. Preferably, as shown in FIG. Figure 1 and 2 As shown, the height adjustment mechanism 112 includes a mounting frame 1121, a connecting frame 1122, and an adjustment knob 1123. The mounting frame 1121 is connected to the movable pulley 111, and the connecting frame 1122 is connected to the base 110. An adjustment rod 1124 is connected below the adjustment knob 1123. The bottom end of the adjustment rod 1124 is connected to the mounting frame 1121. The connecting frame 1122 is provided with a mounting hole. The adjustment rod 1124 is partially inserted into the mounting hole and can drive the mounting frame 1121 to move up and down along the direction of the mounting hole. Of course, the height adjustment mechanism 112 is not limited to the structure mentioned in this embodiment, and it is sufficient to be able to realize the height adjustment function of the movable pulley 111.

[0028] Preferably, a handle 122 is provided on the outer wall of the hydraulic cylinder body 120 to facilitate the transportation, dragging, and holding of the jack body 100.

[0029] This embodiment improves the traditional jack and provides a corner piece connection mechanism 200 that can be detachably connected to the corner piece, and is raised and lowered synchronously with the jack body 100. In this way, by controlling the raising and lowering of the jack body 100, the container is driven to be raised and lowered, and can be used for jacking operations when the container is in a grounded state, so as to cooperate with the handling equipment for rapid handling. It is simple to operate and low in cost, and solves the problems existing in the prior art.
