Description

Technical Field

[0001] The utility model relates to the technical field of municipal bridge steel box girder construction, in particular to an anti-falling alarm and anti-stuck device for a steel box girder cantilever mobile platform. Background Art

[0002] The main method for installing steel box girders is to set up a supporting frame under the main box room and use a non-supported installation method for the cantilever. The installation of the cantilever and the steel guardrail on it has an important impact on the overall installation progress and safe and civilized construction. At present, there are two common practices for installing the cantilever and steel guardrail of municipal bridge steel box girders: (1) Setting up scaffolding on the ground for cantilever installation and using a small hanging basket for welding steel guardrails. In this method, the scaffolding needs to occupy ground space, which has a great impact on traffic and is prone to traffic congestion; (2) The cantilever and steel guardrail are installed using hanging baskets respectively. Because the steel guardrail will affect the movement of the cantilever hanging basket, the steel guardrail can only be installed after the cantilever installation is completed, which affects the installation progress of the steel guardrail. At the same time, the cantilever end cannot be equipped with edge protection, which poses a great safety hazard.

[0003] Patent 201621407536.6 proposes a dual-purpose mobile operating platform for installing steel box girder cantilever and steel guardrail. It is simple to manufacture and highly mobile, eliminating safety hazards during the installation process and shortening the turnover cycle of edge protection. However, the above patent will produce deviations during the movement along the steel box girder cantilever. When the pulley deviates inward, it is easy to get stuck due to the small space with the cantilever edge, and needs to be readjusted, reducing efficiency. When the pulley deviates outward, the equipment cannot issue a timely warning to remind the operator to adjust. There is room for improvement. Therefore, a steel box girder cantilever mobile platform anti-fall alarm and anti-stuck device is proposed to solve the above problems. Utility Model Content
