Technical Field

[0001] The utility model relates to an end beam connection structure, in particular to a novel end beam connection structure of a double-beam bridge crane, belonging to the technical field of bridge cranes. Background Art

[0002] The end beam of a double-girder bridge crane is generally more than 4.5 meters long. In order to facilitate transportation, it is usually cut into two sections and then connected after being transported to the destination. The existing crane end beam connection adopts steel plate connection. The steel plate and the web of the crane end beam are drilled and fastened with bolts to complete the connection of the end beam.

[0003] However, the existing double-girder bridge crane end beam connection adopts ordinary steel plate connection, and the steel plate and the crane end beam web need to be drilled to ensure the accuracy of the end beam after installation. Due to the large size and weight of the end beam, the drilling process is extremely inconvenient, and the steel plate has general strength. It is horizontally connected to the web, and more connecting bolts are needed to ensure its strength. The installation and disassembly require a long time. For this reason, we provide a new double-girder bridge crane end beam connection structure to solve the above problems. Utility Model Content

[0004] In order to solve the above problems, the utility model provides a new type of double-girder bridge crane end beam connection structure to solve the above problems. The specific technical solution is as follows:

[0005] A new type of double-girder bridge crane end beam connection structure includes a left end beam, a right end beam is arranged on one side of the left end beam, the outer surface of the right end beam is welded with a right angle steel, the outer surface of the left end beam is welded with a left angle steel, the outer surface of the right angle steel is welded with an assembly angle steel, the outer surface of the left end beam is welded with a left I-beam, the outer surface of the right end beam is welded with a right I-beam, and the outer surface of the right I-beam is slidably connected to the outer surface of the left I-beam.

[0006] Preferably, a first drilling hole is opened on the upper surface of the left angle steel, and a second drilling hole is opened on the upper surface of the assembly angle steel.

[0007] Preferably, a positioning groove is provided on the outer surface of the left I-beam, and a positioning plate is connected to the outer surface of the right I-beam, and the outer surface of the positioning plate is slidably connected to the inner wall of the positioning groove.

[0008] Preferably, the outer surface of the right I-beam is connected to a right upper and lower plate, and the outer surface of the left I-beam is connected to a left upper and lower plate.

[0009] Preferably, a first connecting hole is provided on the outer surface of the right upper and lower plates, and a second connecting hole is provided on the outer surface of the left upper and lower plates.

[0010] Preferably, a sliding groove is provided on the outer surface of the left upper and lower plates, and a sliding plate is connected to the outer surface of the right upper and lower plates, and the outer surface of the sliding plate is slidably connected to the inner wall of the sliding groove.

[0011] Preferably, there are four left angle steels located on the outer surface of the left end beam, and there are four right angle steels located on the outer surface of the right end beam.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. The new double-girder bridge crane end beam connection structure is achieved through the coordination between the right angle steel, the left angle steel, the assembly angle steel, the right I-beam and the left I-beam. When using the device, first weld the right angle steel to the four corners of the right end beam, then weld the left angle steel to the four corners of the left end beam, and then weld the left I-beam and the right I-beam to one end of the left end beam and the right end beam respectively, connect the left angle steel and the assembly steel together using drill hole 1 and drill hole 2, and then connect the left I-beam and the right I-beam together using connection hole 1 and connection hole 2. This solves the problem that the existing double-girder bridge crane end beam connection uses ordinary steel plates, and the steel plates and the crane end beam webs need to be drilled to ensure the accuracy of the end beam after installation. Due to the large volume and weight of the end beam, the drilling process is extremely inconvenient, and the steel plate strength is average. It is horizontally connected to the web, and more connecting bolts are required to ensure its strength, and the installation and disassembly required working hours are long.

[0014] 2. The new double-girder bridge crane end beam connection structure is achieved through the cooperation between the left end beam, the right end beam, the left I-beam, the positioning groove, the right I-beam and the positioning plate. When using the device, when the left end beam is aligned with the right end beam, the positioning plate on the outer surface of the right I-beam will slide in the positioning groove on the outer surface of the left I-beam. The positioning plate is stuck in the positioning groove, indicating that the left end beam and the right end beam have been aligned, preventing dislocation when connecting the left end beam and the right end beam.

The left angle steel 4 and the right angle steel 3 are both made of Q235 angle steel, which has good plasticity and welding properties. Q235 angle steel is widely used in various buildings and engineering structures, such as room beams, bridges, transmission towers, etc. It is stronger than steel plates and is suitable for bridge connections. The outer surface of the left end beam 1 is welded with a left angle steel 4.

[0023] There are four left angle steels 4, which are located on the outer surface of the left end beam 1. There are four right angle steels 3, which are located on the outer surface of the right end beam 2. When connecting the left end beam 1 with the right end beam 2, it is only necessary to weld the left angle steel 4 to the outer surface of the left end beam 1 and the right angle steel 3 to the outer surface of the right end beam 2, which is convenient for the subsequent connection of the left end beam 1 with the right end beam 2.

[0024] See also Figure 2 , Figure 3 The outer surface of the right angle steel 3 is welded with an assembly angle steel 5, which will be connected to the left angle steel 4 by drilling.

When the left end beam 1 is aligned with the right end beam 2, drilling hole 1 8 will be aligned with drilling hole 2 9, and drilling hole 2 9 is directly above drilling hole 1 8.

[0025] See also Figure 2 , Figure 3 The outer surface of the left end beam 1 is welded with a left I-beam 6, and the outer surface of the right end beam 2 is welded with a right I-beam 7. A positioning groove 10 is provided on the outer surface of the left I-beam 6, and a positioning plate 11 is connected to the outer surface of the right I-beam 7.

The left upper and lower plates 13 are also the internal structure of the left I-beam 6.

[0027] A sliding groove 17 is provided on the outer surface of the left upper and lower plate 13, and a slide plate 15 is connected to the outer surface of the right upper and lower plate 12. The outer surface of the slide plate 15 is slidably connected to the inner wall of the sliding groove 17. The slide plates 15 are distributed on both sides of the right upper and lower plate 12 to facilitate the right upper and lower plate 12 to slide under the left upper and lower plate 13.

[0028] A connecting hole 14 is provided on the outer surface of the right upper and lower plates 12, and a connecting hole 2 16 is provided on the outer surface of the left upper and lower plates 13. When connecting, the outer surface of the assembled angle steel 5 will slide on the outer surface of the left angle steel 4, and the right upper and lower plates 12 of the right I-beam 7 will slide on the left upper and lower plates 13 of the left I-beam 6, so that the connecting hole 14 and the connecting hole 2 16 are finally aligned, and the outer surface of the right I-beam 7 is slidably connected to the outer surface of the left I-beam 6. By connecting the left I-beam 6 and the right I-beam 7 together, the left end beam 1 and the right end beam 2 can be connected together.

[0029] When the utility model is in use: first weld the four right angle steels 3 to the four corners of the right end beam 2. The right angle steel 3 and the assembly angle steel 5 are an integrated structure, so the assembly angle steel 5 is also welded to the outer surface of the right end beam 2, then weld the left angle steel 4 to the four corners of the left end beam 1, then weld the left I-beam 6 to the right end of the left end beam 1, and then weld the right I-beam 7 to the left end of the right end beam 2. After the welding work is completed, the left end beam 1 and the right end beam 2 are docked, and the left end beam 1 is aligned with the right end beam 2. The positioning plate 11 on the outer surface of the right I-beam 7 will slide in the positioning groove 10 on the outer surface of the left I-beam 6. The positioning plate 11 is stuck in the positioning groove 10, indicating that the left end beam 1 and the right end beam 2 have been aligned. It can prevent dislocation when connecting the left end beam 1 and the right end beam 2. During connection, the outer surface of the assembly angle steel 5 will slide on the outer surface of the left angle steel 4, and the right upper and lower plates 12 of the right I-beam 7 will slide on the left upper and lower plates 13 of the left I-beam 6, and finally align the connection hole 14 with the connection hole 2 16. Finally, the left angle steel 4 and the assembly angle steel 5 are connected together using the drilling hole 1 8 and the drilling hole 2 9, and the left upper and lower plates 13 of the left I-beam 6 and the right upper and lower plates 12 of the right I-beam 7 are connected together using the connecting hole 14 and the connecting hole 2 16, thereby completing the connection between the left end beam 1 and the right end beam 2, thereby avoiding drilling processing on the outer surface of the end beam and reducing the installation time.
