Detailed Description

The present invention will be described in further detail with reference to specific examples, which are provided for illustrative purposes only, and are not intended to be limiting, and the scope of the present invention should not be limited thereby.

The utility model provides a portable extension overhauls platform which innovation part lies in: the device comprises a mobile platform unit 13 and an extension platform unit 12, wherein the extension platform unit is arranged on the side part of the mobile platform unit in a folding way;

the movable platform unit comprises a movable underframe and guardrails 6, wherein the guardrails are arranged on the left side and the right side of the movable underframe, and an inlet and an outlet 7 are reserved between the guardrails on the left side and the right side; the movable underframe comprises supporting legs 9, brake wheels 11, an operation bottom plate 8 and ladder bars 10, wherein the supporting legs are arranged at four corners of the bottom of the operation bottom plate, the brake wheels are arranged at the bottoms of the supporting legs, the ladder bars are uniformly distributed between the two supporting legs at one side corresponding to the inlet and the outlet at intervals, and the ladder bars and the supporting legs form a ladder for a maintainer to climb to the operation bottom plate;
