Automatic telescopic operation platform for large-span large-variable-span-range variable coating steel form trolley

Abstract

The invention belongs to the technical field of underground cave depot concrete lining construction equipment, and discloses an automatic telescopic operation platform for a large-span large-variable-span-range variable coating steel form trolley. An inside end face telescopic guardrail stand column and an outside end face telescopic guardrail stand column are arranged on the inner side and the outer side of an end face telescopic guardrail. An end face guardrail telescopic pipe is arranged over the end face telescopic guardrail. The inner side and outer side of the end face guardrail telescopic pipe are separately connected with the inside end face telescopic guardrail stand column and the outside end face telescopic guardrail stand column through bolts used for connecting the inside end face telescopic guardrail stand column and the end face guardrail telescopic pipe and bolts used for connecting the end face guardrail telescopic pipe and the outside end face telescopic guardrail stand column. The outside end face telescopic guardrail stand column is hinged to the inner side of a door through a rotary pair. The operation platform has the advantages of being large in span and variable-span range, high in automation degree, convenient to control and operate, stable and reliable in work performance and the like.

Description

technical field [0001] The invention belongs to the technical field of concrete lining construction equipment for underground caverns, and in particular relates to an automatic retractable operation platform of a large-span and large-span range-variable covered steel mold trolley. Background technique [0002] Concrete clad steel formwork trolley is an indispensable non-standard product for secondary lining in the construction process of underground caverns. Steel mold trolleys commonly used in engineering have different structural forms such as simple type, full hydraulic type and grid type. Generally, they are equipped with an operating platform that is connected by bolts, fixed on the frame system of the trolley, and equipped with protective fences around it. The staff operates and controls the vehicle, and at the same time temporarily stores the machine tools. In recent years, in order to meet the concrete covering requirements of variable-section caverns with different...

AI Technical Summary

Problems solved by technology

[0003] With the rapid development of my country's national defense military missile base construction projects and the continuous expansion of infrastructure such as transportation and energy, large-scale caverns with variable cross-sectional shapes and spans of more than 6m are emerging. The traditional fixed operating platform cannot meet the needs of steel mold trolleys. Requirements
