[0001] This utility model relates to the technical field of gantry crane bases, specifically a base for gantry crane installation. Background Technology

[0002] A gantry crane is a variation of a bridge crane, employing a gantry structure. It consists of two legs and a ground rail forming a frame. Based on their application, they can be categorized into large gantry cranes and small portable gantry cranes, primarily used for loading and unloading cargo in outdoor freight yards, docks, and other similar locations. Their core structure includes components such as the main beam, legs, rails, and hook, and they are characterized by high site utilization, a large operating range, and strong adaptability.

[0003] The base of a small portable gantry crane cannot be height adjusted, making it impossible to lift items to higher positions, which limits the practicality of the device. To address this issue, a base for gantry crane installation is proposed. Utility Model Content

[0017] 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.

[0018] Example: Figure 1 - Figure 4 As shown, this utility model provides a base for gantry crane installation, including a horizontal frame 1. There are two horizontal frames 1. It is worth noting that both sides of the bottom end of the horizontal frame 1 are fixedly installed with moving wheels. A vertical frame 2 is fixedly installed at the center of the top end of the horizontal frame 1. The gantry frame is installed on the top end of the vertical frame 2. A support rod 3 is slidably connected to the inner cavity of the vertical frame 2. A sliding groove 7 is symmetrically opened at the top end of the horizontal frame 1. An adjustment component is provided inside the sliding groove 7. The support rod 3 can move up or down inside the vertical frame 2 through the adjustment component. The adjustment assembly includes a threaded block 9 slidably connected inside the slide groove 7. A threaded rod 8 is installed on the radial inner wall of the threaded block 9 through internal and external thread engagement. A connecting shaft 15 is connected between the two threaded rods 8. Driven by a servo motor, the threaded rod 8 rotates clockwise. Under the linkage of the connecting shaft 15, the two threaded rods 8 rotate synchronously. During the rotation, the threaded block 9 slides laterally inside the slide groove 7. During the sliding process, the adjustment rod 5 changes its tilt angle under the mutual engagement of the first connecting frame 4 and the second connecting frame 6, thereby pushing the support rod 3 to move upward inside the upright frame 2, and vice versa. When the servo motor drives the threaded rod 8 to rotate counterclockwise, the threaded block 9 slides inside the slide groove 7 in a direction away from the upright 2. At this time, the tilt angle of the adjusting rod 5 is reset again, causing the support rod 3 to move down inside the upright 2. The first connecting frame 4 is fixedly installed on both opposite sides of the surface of the support rod 3, and the second connecting frame 6 is fixedly installed on the top of the threaded block 9. The adjusting rod 5 is rotatably connected between the first connecting frame 4 and the second connecting frame 6. A limiting component is provided on the side of the cross frame 1 near the slide groove 7, and the threaded block 9 is limited and fixed by the limiting component.

[0019] The limiting component includes a through groove 12 formed inside one side of the slide groove 7. An L-shaped bracket 13 is fixedly connected to one side of the threaded block 9 through the through groove 12. A limiting frame 14 is slidably connected to the surface of the L-shaped bracket 13. A spring assembly is provided on the inner ring surface of the limiting frame 14. The limiting component also includes limiting plates 10 fixedly installed on both sides of the top of the cross frame 1. A through groove 11 adapted to the limiting frame 14 is formed on the surface of the limiting plate 10. A limiting hole adapted to the limiting frame 14 is formed on the side of the second connecting frame 6 facing the limiting plate 10.

[0020] By adopting the above technical solution, before the threaded block 9 slides, the limiting bracket 14 is pulled out from the limiting hole on one side of the second connecting bracket 6 and the through groove 11 on the surface of the limiting plate 10, so that the threaded block 9 can be slidably adjusted. After the support rod 3 has been adjusted, the limiting bracket 14 is released and, under the elastic force of the spring assembly, one end of the limiting bracket 14 is pushed through the through groove 11 again and into the limiting hole on one side of the second connecting bracket 6, thereby limiting the threaded block 9 and preventing the servo motor from running for a long time and causing motor fatigue and loss of force.

[0021] A cavity 101 is provided at the bottom of the cross frame 1. A toothed plate 102 is slidably connected to both sides of the cavity 101. An extension plate 104 is fixedly installed on one side of the toothed plate 102. A pre-embedded groove is provided at the center of the cavity 101. A servo motor is fixedly installed inside the pre-embedded groove. The output end of the servo motor is driven by a transmission gear 103 that is compatible with the toothed plate 102.

[0022] By adopting the above technical solution, after the support rod 3 has moved up inside the upright 2, the center of gravity will become higher. At this time, the servo motor needs to be started to drive the transmission gear 103 to rotate. During the rotation of the transmission gear 103, the two toothed plates 102 slide towards the outside of the cross frame 1 at the same time, and the extension plate 104 extends to the outside of the cross frame 1 to increase the stability of the cross frame 1.

[0023] Working principle: Driven by the servo motor, the threaded rod 8 rotates clockwise. Under the linkage of the connecting shaft 15, the two threaded rods 8 rotate synchronously. During rotation, the threaded block 9 slides laterally inside the slide groove 7. During this sliding process, the adjusting rod 5 changes its tilt angle under the interaction of the first connecting frame 4 and the second connecting frame 6, thereby pushing the support rod 3 upward inside the upright frame 2. Before the threaded block 9 slides, the limiting frame 14 is pulled out from the limiting hole on one side of the second connecting frame 6 and the through groove 11 on the surface of the limiting plate 10, allowing for sliding adjustment of the threaded block 9. When the support rod 3 completes its movement... After adjustment, the limit bracket 14 is released. Under the elastic force of the spring assembly, one end of the limit bracket 14 passes through the through slot 11 again and springs into the limit hole on one side of the second connecting bracket 6 to limit the threaded block 9, thus preventing the servo motor from running for a long time and causing motor fatigue and loss of force. After the support rod 3 moves up inside the upright 2, the center of gravity will become higher. At this time, the servo motor needs to be started to drive the transmission gear 103 to rotate. During the rotation of the transmission gear 103, the two toothed plates 102 slide towards the outside of the cross frame 1 at the same time, and the extension plate 104 extends to the outside of the cross frame 1 to increase the stability of the cross frame 1.

[0024] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
