[0037] It should be noted that the features in the embodiments of the utility model can be combined with each other without conflict.

[0038] The connecting seat of the aerial work platform mostly includes swing cylinder mounting part, transition connecting part and basket mounting part arranged in sequence, for some existing transition connecting parts, mostly formed by two connecting plates arranged at an angle, one of which is connected with the swing cylinder mounting part, and the other is connected with the basket mounting part, and the two connecting plates are mostly connected by welding or screwing, when the aerial work platform is frequently swung or bears a large load, the transition connecting part of the connecting seat is prone to deformation, which in turn easily causes the connected basket to shake, and the stability is poor.

[0039] The embodiment provides a connecting seat of an aerial work platform, which can reduce the deformation amount of the connecting seat when the aerial work platform is frequently swung or bears a large load, thereby ensuring the stability of the basket 3 connected with the connecting seat during high-altitude operation.

The transition connecting part 200 is used for supporting the basket 3 together with the basket mounting part 300, and the transition connecting part 200 comprises a connecting beam 210, one end of the connecting beam 210 is connected with the basket mounting part 300, and the swing cylinder mounting part 100 is connected with the connecting beam 210.

[0042] In the embodiment, the connecting beam 210 comprises a first bent plate 211, which comprises a first support plate 2112 and a second support plate 2113 connected at an angle and integrally formed, the first support plate 2112 is arranged opposite to the outer periphery of the basket 3, and the second support plate 2113 is arranged abutting against the bottom of the basket 3 and connected with the basket mounting portion 300. In the embodiment, the connecting beam 210 is a box-shaped bent beam.

[0043] It can be understood that, since the connecting beam 210 connecting the swing cylinder mounting portion 100 and the basket mounting portion 300 is a box-shaped bent beam in the embodiment, the box-shaped connecting beam 210 can increase the bending resistance of the connecting beam 210 and improve the torsional stiffness, which can effectively reduce the deformation of the connecting seat when the aerial work platform is frequently swinging or bearing a large load, thereby ensuring the stability of the basket 3 connected by the connecting seat during aerial work.

[0044] Moreover, since the first bent plate 211 in the connecting beam 210 comprises a first support plate 2112 and a second support plate 2113 connected at an angle and integrally formed, the first support plate 2112 is arranged opposite to the outer periphery of the basket 3, and the second support plate 2113 is arranged abutting against the bottom of the basket 3 and connected with the basket mounting portion 300, the first support plate 2112 and the second support plate 2113 are two bent parts integrally formed by the first bent plate 211, the first support plate 2112 and the second support plate 2113 constitute a continuous and seamless joint overall structure, and there is no physical joint or separation interface at the connection between the first support plate 2112 and the second support plate 2113, which ensures the strength of the first bent plate 211, thereby effectively reducing the deformation at the connection between the first support plate 2112 and the second support plate 2113, thereby ensuring the stability of the basket 3 connected by the connecting seat during aerial work.

[0045] In the embodiment, the transition connecting portion 200 comprises two connecting beams 210 arranged at intervals along the extension direction of the basket mounting portion 300. It can be understood that, by arranging two connecting beams 210, the connection strength with the basket mounting portion 300 is effectively improved, the connection strength with the swing cylinder mounting portion 100 is also improved, and the support capacity for the basket 3 is also improved, thereby effectively improving the stability of the connecting beam 210 supporting the basket 3 during aerial work.

[0046] Of course, in some other optional embodiments, the number of the connecting beams 210 is not limited to two, and can be one or more. In the embodiment, a plurality of connecting beams 210 can be understood as two or more connecting beams 210.
