WIPO Patent Application WO/2021/129084
Kind Code:
A1
Abstract:
A modular assembly operation platform apparatus of a portal frame-free lining trolley. At least five top supporting beam bodies (3) are longitudinally arranged above a combined frame body (1), and the two sides of the lower ends of the top supporting beam bodies (3) and side beam bodies (4) are configured to be arch-shaped frame bodies; a pair of upper operation platform modules (5) is symmetrically provided on the two sides of the upper portion between every two adjacent arch-shaped frame bodies, and a top manual operation platform is formed by four pairs of upper operation platform modules (5) on the upper portions of at least five arch-shaped frame bodies; two symmetrical middle manual operation platforms are formed by four pairs of symmetrical middle operation platform modules (6) on the two sides of the arched frame bodies; two lower manual operation platforms are formed by four pairs of symmetrical lower operation platform modules (7) on the two sides of the arched frame bodies. The operation platform adopts the operation platform apparatus assembled in a modular mode, the platform modules are respectively the prefabricated upper operation platform modules (5), the prefabricated middle operation platform modules (6), and the prefabricated lower operation platform modules (7); after construction is completed, the manual operation platform modules can be disassembled and repeatedly used, and safety production and use are guaranteed.
