Double-rotation telescopic luffing platform, hydraulic system of leveling mechanism and control method

Abstract

The invention relates to a double-rotation telescopic luffing lifting platform, a leveling mechanism hydraulic system and a control method, wherein the double-rotation telescopic luffing lifting platform includes a base structure, a primary turntable mechanism, a main arm assembly, and a secondary turntable mechanism and the working platform; the base structure is connected with the primary turntable mechanism through the primary rotary mechanism, the main arm assembly includes a basic arm and a telescopic arm slidingly connected with the basic arm, the basic arm of the main arm assembly is hinged with the primary turntable mechanism, And there is a luffing oil cylinder between the primary turntable mechanism and the basic arm of the main arm assembly; the secondary turntable mechanism is hinged with the telescopic arm of the main arm assembly, and the secondary turntable mechanism is connected to the working platform through a secondary rotary mechanism; Includes a leveling mechanism that keeps the work platform level at all times during luffing of the boom assembly. The present invention enables the operation platform to realize full-area operation during the construction and maintenance of the inner wall of the tunnel, catenary and related network frames through the primary rotary mechanism and the secondary rotary mechanism.

Description

technical field [0001] The invention belongs to the technical field of high-altitude manned lifting construction for rails, and in particular relates to a double-rotation telescopic luffing lifting platform, a hydraulic system of a leveling mechanism and a control method. Background technique [0002] Now that electrified lines have been fully popularized, and the proportion of line tunnels has increased, the demand for construction and maintenance of electrified line-related facilities such as catenary and catenary cables, as well as the construction and maintenance of tunnel inner walls, has increased sharply, requiring equipment to replace construction and maintenance personnel. Send it to a suitable height for construction and maintenance of overhead catenary, catenary cables, insulators, tripods, etc. [0003] In the existing technology, in order to realize the construction and maintenance of the inner wall of the tunnel, catenary and related grids, a lifting aerial wor...

AI Technical Summary

Problems solved by technology

[0003] In the existing technology, in order to realize the construction and maintenance of the inner wall of the tunnel, catenary and related grids, a lifting aerial work platform is generally installed on the rail locomotive. The platform supports the manned platform to rise through the scissor structure or the column telescopic structure. Or the main mechanism action taken by the column telescopic structure is vertical lifting, relying on vertical lifting to lift the people and materials in the working platform to a certain height; but the above two structures are limited by the structure in the side and front and rear directions , unable to reach the corresponding area, the operating range is small, and the flexibility is poor. In many cases on site, the operator needs to climb on the catenary pole and the rope, which is inconvenient and dangerous.
