Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be obtained by a person skilled in the art without making any creative effort based on the embodiments in the present invention, belong to the protection scope of the present invention.

As shown in the attached drawings 1-4, the aerial work platform comprises a work platform 1, a lifting structure 2, an underframe 3, a guide assembly 4 and a guide rail 5.

The guide rail 5 is installed on the ground, and the guide rail 5 is a single rail and is arranged on the ground of the traveling path of the aerial work platform. The guide assemblies 4 are installed below the base frame 3, and one guide assembly 4 is installed at each of the front and rear sides below the base frame 3.

The guide assembly 4 consists of a guide seat 10 and a guide wheel 6.

A cylindrical mounting shaft 101 is arranged on one side of the guide seat 10, and the mounting shaft 101 is rotatably connected with a through hole in the bottom of the bottom frame 3 through a bearing 7. An end cover 8 is arranged above the bearing 7, a hole is formed in the middle of the end cover 8, the mounting shaft 101 penetrates through the bearing 7 and the end cover 8 from bottom to top, a groove is formed in the mounting shaft 101 on the outer side of the end cover 8, and a shaft retainer ring 9 is arranged in the groove.
