Description

Technical Field

[0001] The present invention belongs to the technical field of bridge structures, and particularly relates to a modular bridge structure. Background Art

[0002] A bridge is a load-bearing structure that spans over workshops, warehouses, and yards to carry trolleys for material hoisting.

[0003] In the prior art, the lengths of the main girders and end girders of a crane bridge are fixed, which means that the span and trolley gauge of the crane bridge are fixed. However, in engineering project construction, crane relocation often occurs, and it is necessary to change the span and trolley gauge of the crane to meet the new installation conditions. For newly manufactured cranes, once situations such as users terminating contracts or changing the span and trolley gauge occur, the already manufactured bridge will face overall scrapping, resulting in great waste and huge economic losses. Summary of the Invention

[0004] To at least partially solve the technical problems existing in the above prior art, the present invention provides a modular bridge structure.

[0005] The modular bridge structure of the present invention includes 4 bridge ends, 2 main girder middle sections, and 2 end girder middle sections. The 2 main girder middle sections are longitudinally arranged between every 2 bridge ends, and the 2 end girder middle sections are transversely arranged between every two bridge ends, where:

[0006] The bridge end includes an end body, a first connection port, a second connection port, and a connection component. The first connection port is arranged at one longitudinal end of the end body, the second connection port is arranged at one transverse end of the end body, and the connection component is arranged around the first connection port and the second connection port.

[0007] Further, in the above modular bridge structure, the end body is arranged in an L shape, the end body is longitudinally matched with the main girder middle section, the end body is transversely matched with the end girder middle section, a first rectangular boss is arranged in the middle of the first connection port, and a second rectangular boss is arranged in the middle of the second connection port.

[0008] Further, in the above modular bridge structure, third connection ports are arranged at both ends of the main girder middle section, a first rectangular groove is arranged in the middle of the third connection port, the first rectangular groove is matched with the first rectangular boss, the first rectangular boss is inserted into the first rectangular groove, and the first connection port and the third connection port are fixedly connected through the connection component.

[0009] Further, in the above modular bridge structure, fourth connection ports are provided at both ends of the middle section of the end beam. A second rectangular groove is provided in the middle of the fourth connection port. The second rectangular groove matches the second rectangular boss. The second rectangular boss is inserted into the second rectangular groove. The second connection port and the fourth connection port are fixedly connected through the connection component.

[0022] To make the objectives, technical solutions and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with specific embodiments of the present invention and the corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the scope of protection of the present invention.

[0023] As Figures 1 to 5 shown, the modular bridge structure of the present invention includes 4 bridge ends 1, 2 middle sections of main beams 2 and 2 middle sections of end beams 3. The 2 middle sections of beams are longitudinally arranged between every 2 bridge ends 1, and the 2 middle sections of end beams 3 are transversely arranged between every two bridge ends 1, wherein:

[0024] The bridge end 1 includes an end body 11, a first connection port 12, a second connection port 13 and a connection component 14. The first connection port 12 is arranged at one longitudinal end of the end body 11, the second connection port 13 is arranged at one transverse end of the end body 11, and the connection component 14 is arranged around the first connection port 12 and the second connection port 13.

[0025] Further, in the modular bridge structure of the present invention, the end body 11 is arranged in an L shape. The longitudinal direction of the end body 11 matches the middle section of the main beam 2, and the transverse direction of the end body 11 matches the middle section of the end beam 3. A first rectangular boss 121 is arranged in the middle of the first connection port 12, and a second rectangular boss 131 is arranged in the middle of the second connection port 13, so as to connect the end body 11 with the middle section of the main beam 2 and the middle section of the end beam 3, and at the same time prevent the middle section of the main beam 2 and the middle section of the end beam 3 from rotating after connection.

[0026] Further, in the modular bridge structure of the present invention, third connection ports 21 are arranged at both ends of the middle section of the main beam 2. A first rectangular groove 211 is arranged in the middle of the third connection port 21. The first rectangular groove 211 matches the first rectangular boss 121. The first rectangular boss 121 is inserted into the first rectangular groove 211. The first connection port 12 and the third connection port 21 are fixedly connected through the connection component 14, thus effectively ensuring the connection of the middle section of the main beam 2.

[0027] Furthermore, in the modular bridge structure of the present invention, fourth connection ports 31 are provided at both ends of the middle section 3 of the end beam. A second rectangular groove 311 is provided in the middle of the fourth connection port 31. The second rectangular groove 311 matches the second rectangular boss 131. The second rectangular boss 131 is inserted into the second rectangular groove 311. The second connection port 13 and the fourth connection port 31 are fixedly connected by a connection component 14, thus effectively ensuring the connection of the middle section 3 of the end beam.

[0028] Specifically, during installation, first select the middle section 2 of the main beam and the middle section 3 of the end beam with appropriate specification lengths. Insert the first rectangular boss 121 in the middle of the first connection port 12 on the bridge end 1 into the first rectangular groove 211 in the middle of the third connection port 21 on the middle section 2 of the main beam, and fix the first connection port 12 and the third connection port 21 through the connection component 14. Then insert the second rectangular boss 131 in the middle of the second connection port 13 on the bridge end 1 into the second rectangular groove 311 in the middle of the fourth connection port 31 on the middle section 3 of the end beam, and fix the second connection port 13 and the fourth connection port 31 through the connection component 14. When the crane span needs to be changed, only need to remove the connection component 14 and replace the middle section 2 of the main beam and the middle section 3 of the end beam with appropriate specification lengths.

[0029] In summary, compared with the prior art, the modular bridge structure of the present invention has the following advantages and beneficial effects:

[0030] The overall structure of the present invention is simple. By modularizing the bridge into the middle section of the main beam, the middle section of the end beam and the bridge end, a crane bridge with any required span and gauge can be combined, which is convenient for serialized, modular and automated production, effectively improves the production efficiency, and at the same time effectively ensures that it can be adjusted according to the installation space after relocation, effectively avoids waste and reduces economic losses.
