Description

Technical Field

[0001] This utility model relates to the field of gantry cranes, and in particular to an anti-tipping structure for gantry cranes. Background Technology

[0002] A gantry crane (commonly known as a "gantry crane") is a type of bridge-type lifting equipment. Its portal metal frame consists of a main beam, two side legs, and a lower crossbeam. The entire machine is supported on rails on the ground. The trolley moves longitudinally along the rails via a trolley traveling mechanism, while the trolley moves laterally on the main beam, thus realizing the vertical lifting and horizontal transport of heavy objects.

[0003] A search revealed a gantry crane anti-tipping structure disclosed in Chinese Patent No. CN 222374196 U, which includes a gantry crane body. Multiple side frames are fixedly installed on the outer side of the gantry crane body. A lifting groove is provided on one side of each side frame, and a lifting block is movably installed within the lifting groove. A lifting drive mechanism for the lifting block is provided on the side frame. An mounting plate is fixedly installed on one side of each lifting block, and a drilling motor is fixedly installed on the top side of the mounting plate. This invention, by setting drill rods at each of the four corners of the gantry crane body, uses multiple sets of lifting drive mechanisms to spirally drill into the ground. When a suitable depth is reached, multiple hydraulic push rods are opened, causing multiple sets of first and second extension plates within the four drill rods to simultaneously unfold and insert into the surrounding soil, thereby improving the stability of the gantry crane body and reducing the likelihood of collapse.

[0004] However, the aforementioned anti-tipping structure for gantry cranes does not allow the entire gantry crane to move during use, thus presenting certain limitations.

[0005] Therefore, it is essential to invent an anti-tipping structure for gantry cranes. Utility Model Content

[0006] To solve the above-mentioned technical problems, this utility model provides a technical solution for an anti-tipping structure for a gantry crane: an anti-tipping structure for a gantry crane includes an anti-tipping frame, wherein: the anti-tipping frame includes an I-beam base, a first gantry frame, and a second gantry frame; the upper ends of both ends of the I-beam base are fixedly connected to the bottoms of the first and second gantry frames respectively; a gantry crane guide rail is fixedly installed on each side between the first and second gantry frames; the gantry crane guide rail is located above the I-beam base; at least one guide column can be fixedly installed between the crossbeams of the first and second gantry frames; a support plate is slidably installed on the guide column; and the support plate is fixedly connected to the crossbeam of the gantry crane.

[0007] The I-shaped base and the portions of gantry frame one and gantry frame two located below the guide rail are all pre-embedded in the foundation.

[0008] Each of the crossbeams of the gantry frame one and the gantry frame two has a through hole corresponding to a guide post, and the guide post is fixedly installed in the through hole.

[0009] The support plate has a through hole two corresponding to the guide post, and the support plate is slidably sleeved on the guide post through the through hole two.

[0010] One end of the guide post is coaxially fixed with an anti-detachment head, and the other end of the guide post is threaded with a nut. The end of the guide post connected to the nut extends out from the through hole one of the gantry frame two. The diameters of the anti-detachment head and the nut are both larger than the diameter of the through hole one.

[0011] The base of the character, gantry frame one, gantry frame two, guide rail, guide column, and support plate are all treated with anti-corrosion measures.

[0012] Compared with the prior art, the advantages of this utility model are:

[0013] The overall design of this utility model not only ensures the stability of the gantry crane during use, but also prevents it from tipping over, while not affecting the overall movement of the gantry crane, thus making the entire system safer, more flexible, and more reliable during use.

[0021] The present invention will be further described below with reference to the accompanying drawings: Example

[0022] Reference Figure 1-3 An anti-tipping structure for a gantry crane includes an anti-tipping frame, wherein the anti-tipping frame includes an I-beam base 1, a first gantry frame 2, and a second gantry frame 3. The upper ends of both ends of the I-beam base 1 are fixedly connected to the bottom of the first gantry frame 2 and the second gantry frame 3, respectively, to ensure the stability of the I-beam base 1, the first gantry frame 2, and the second gantry frame 3. A guide rail 4 for the gantry crane 7 is fixedly installed on each side between the first gantry frame 2 and the second gantry frame 3, so that the gantry crane 7 can move linearly along the guide rail 4. The guide rail 4 of the gantry crane is located above the I-beam base 1. Three guide columns 5 are evenly fixedly installed between the crossbeams of the first gantry frame 2 and the second gantry frame 3. A support plate 6 is slidably installed on the guide column 5. The support plate 6 is fixedly connected to the crossbeam of the gantry crane 7, so as to limit the movement of the gantry crane 7 through the guide columns 5 and the support plate 6, and ensure the stability between the gantry crane 7 and the anti-tipping frame.

[0023] Specifically, the I-beam base 1, as well as the portions of gantry frame 1 2 and gantry frame 2 3 located below the guide rail 4, are all pre-embedded in the foundation 12 to ensure the stability of the anti-tilting frame after installation with the gantry crane 7. The anti-tilting frame is fixed by the foundation 12 to prevent it from tilting, thereby preventing the gantry crane 7 from tipping over.

[0024] Specifically, each of the crossbeams of gantry frame 12 and gantry frame 23 has a through hole 8 corresponding to the guide post 5. The guide post 5 is fixedly installed in the through hole 8 so as to position and install the guide post 5.

[0025] Specifically, the support plate 6 has a through hole 2 9 corresponding to the guide post 5. The support plate 6 is slidably sleeved on the guide post 5 through the through hole 2 9 so that the support plate 6 can slide stably and smoothly along the guide post 5.

[0026] Specifically, an anti-detachment head 10 is coaxially fixedly installed at one end of the guide post 5, and a nut 11 is threaded onto the other end of the guide post 5. The end of the guide post 5 connected to the nut 11 extends out from the through hole 8 of the second gantry 3. The diameters of the anti-detachment head 10 and the nut 11 are both larger than the diameter of the through hole 8. This structure ensures the stability between the guide post 5 and the first gantry 2 and the second gantry 3, while also facilitating the separate disassembly and assembly of the guide post 5 later.

[0027] Specifically, the base 1, gantry 1, gantry 2, gantry 2, guide rail 4, guide column 5, and support plate 6 are all treated with anti-corrosion measures, such as anti-corrosion coatings and electrochemical treatments.

[0028] In this embodiment, as Figure 1 As shown, during use, the parts of the I-beam base 1, gantry frame 1 2, and gantry frame 2 3 located below the guide rail 4 are all pre-embedded in the foundation 12.

[0029] In this way, when the gantry crane 7 is in operation, the top and bottom of the gantry crane 7 are always connected to the anti-tilt frame, which can stably support and limit the gantry crane 7, prevent the top of the gantry crane 7 from tilting downwards, and does not affect the loading and unloading of goods by the gantry crane 7.

[0030] Any technical solution that achieves the above-mentioned technical effects by utilizing the technical solution described in this utility model, or by designing a similar technical solution inspired by the technical solution described in this utility model, falls within the protection scope of this utility model.
