Description

Technical Field

[0001] This utility model relates to container lifting technology, and in particular to a self-leveling electric lifting device. Background Technology

[0002] Currently, when placing containers on semi-trailers, the containers are lifted and placed on the semi-trailers, thus enabling the semi-trailers to transport the containers.

[0003] Existing container lifting devices often fail to lift the container so that its bottom is level, leaving space underneath for the semi-trailer to move. This would allow the semi-trailer to move under the container, place the container on the semi-trailer, and enable the semi-trailer to transport the container. Utility Model Content

[0004] The purpose of this utility model is to provide a self-leveling electric lifting device to solve the problem that existing container lifting devices are often inconvenient to lift the container so that the bottom of the container is set horizontally, leaving space underneath the container for the semi-trailer to move.

[0005] To solve the above problems, this utility model provides a self-leveling electric lifting device, including a screw jack. The screw jack is provided with a support rod that can move up and down with the rotation of the screw. A circular plate is fixed to the bottom of the support rod. A connector is fixedly installed on the top of the screw jack. A fixed seat is provided on the connector. A stud is fixed to the bottom of the circular plate. A rotating seat is threadedly connected to the stud. A threaded hole is opened at the bottom of the rotating seat. A removable pad is threadedly connected to the threaded hole.

[0006] The self-leveling electric lifting device provided by this utility model also has the following technical features:

[0007] Furthermore, the bottom of the rotating seat is provided with an annular support, and a screw is threadedly connected to the circular plate, the bottom end of which can contact the upper side of the annular support.

[0008] Furthermore, a rotating shaft is fixed on the connector, and the rotating shaft is rotatably connected to the fixed base.

[0009] Furthermore, a positioning plate is bolted to one side of the fixing base.

[0010] Furthermore, the bottom of the pad is tapered.

[0011] Furthermore, the fixing base has multiple through holes.

[0012] This utility model has the following beneficial effects: By installing four fixed seats on the container, with two fixed seats installed on each of the opposite sides of the container, the four fixed seats are installed at the four corners of the container. By installing the four fixed seats at the same height, and by simultaneously activating four screw jacks, the support rods of the screw jacks lift the container, and the four support rods move synchronously, so that the container is set horizontally, which plays a self-leveling role. After the container is lifted, there is space under the container for the semi-trailer to move, allowing the semi-trailer to move under the container and place the container on the semi-trailer, thereby realizing the semi-trailer driving the container for transfer. Attached Figure Description

[0013] Figure 1 This is an isometric view of an embodiment of the present utility model;

[0014] Figure 2 This is a perspective view of an embodiment of the present utility model;

[0015] Figure 3 This is a front sectional view of the fracture in an embodiment of the present invention. Detailed Implementation

[0016] The present invention will be described in detail below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of the present invention can be combined with each other.

[0017] like Figures 1 to 3 In the embodiment of the self-leveling electric jacking device of this utility model shown, the self-leveling electric jacking device includes a screw jack 1, a support rod 2 that can move up and down with the rotation of the screw jack 1, a circular plate 3 fixed to the bottom of the support rod 2, a connector 4 fixedly installed on the top of the screw jack 1, a fixing seat 5 on the connector 4, a stud 6 fixed to the bottom of the circular plate 3, a rotating seat 7 threadedly connected to the stud 6, a threaded hole at the bottom of the rotating seat 7, and a removable pad 8 threadedly connected inside the threaded hole. Through the setting of the rotating seats 7, even on uneven surfaces, rotating the rotating seats 7 ensures that none of the four rotating seats 7 are suspended, and the pad 8 can cooperate with the rotation. The seat 7 serves as a support. By installing four fixed seats 5 on the container, with two fixed seats 5 installed on each of the opposite sides of the container, the four fixed seats 5 are installed at the four corners of the container. By installing the four fixed seats 5 at the same height, and by simultaneously activating the four screw jacks 1, the support rods 2 of the screw jacks 1 lift the container, and the four support rods 2 move synchronously, so that the container is set horizontally, which plays a self-leveling role. After the container is lifted, there is space under the container for the semi-trailer to move, so that the semi-trailer can move under the container and place the container on the semi-trailer, thereby realizing the semi-trailer driving the container for transfer.

[0018] In one embodiment of this application, preferably, the bottom of the rotating seat 7 is provided with an annular support 9, and a screw 10 is threadedly connected to the circular plate 3. The bottom end of the screw 10 can contact the upper side of the annular support 9. By rotating the screw 10, the bottom end of the screw 10 can contact the upper side of the annular support 9, thereby further limiting the position of the rotating seat 7 after adjustment.

[0019] In one embodiment of this application, preferably, a rotating shaft 11 is fixed on the connecting member 4, and the rotating shaft 11 is rotatably connected to the fixed seat 5. Through the arrangement of the connecting member 4, the rotating shaft 11 and the fixed seat 5, the position of the corresponding screw jack 1 can be rotated, so as to avoid potholes to a certain extent.

[0020] In one embodiment of this application, preferably, a positioning plate 12 is bolted to one side of the fixing seat 5. The positioning plate 12 can connect two fixing seats 5 on the same side, thereby facilitating the positioning of the two fixing seats 5 on the same side.

[0021] In one embodiment of this application, preferably, the bottom of the pad 8 is tapered.

[0022] In one embodiment of this application, preferably, the mounting base 5 is provided with a plurality of through holes 13. The through holes 13 facilitate the installation of the mounting base 5 and the container by passing bolts through the through holes 13.

[0023] In use, this utility model involves installing four fixed seats 5 on the container, with two fixed seats 5 installed on each of the opposite sides of the container. These four fixed seats 5 are positioned at the four corners of the container. By installing the four fixed seats 5 at the same height, even on uneven surfaces, rotating the rotating seat 7 ensures that none of the four rotating seats 7 are suspended in mid-air. The pads 8 cooperate with the rotating seats 7 to provide support. Rotating the screw 10 allows its bottom end to contact the upper side of the annular support 9, further limiting the position of the rotating seat 7 after adjustment. Simultaneously activating four screw jacks 1 causes their support rods 2 to lift the container, and the four support rods 2 move synchronously, resulting in a horizontally positioned container that self-levels. After the container is lifted, space is left underneath for the semi-trailer to move, allowing the semi-trailer to move under the container and place the container on it, thus enabling the semi-trailer to transport the container.

[0024] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
