Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of formwork support, and particularly relates to a mobile lifting locking device for a large formwork support system. BACKGROUND

[0002] The large formwork support system bears the heavy responsibility of supporting the large formwork in the construction, and is mainly composed of two parts of the large formwork and the support. The large formwork is mostly a large-area steel formwork or wood formwork, which is used to shape the appearance surface of the concrete structure. The support is constructed by materials such as profile steel and steel pipe, and is responsible for supporting and stabilizing the large formwork by virtue of its sufficient strength and rigidity, so as to ensure that the formwork is always in a stable and correct position during the concrete pouring to bear the lateral pressure of the concrete and various construction loads.

[0003] The lifting function of the large formwork support system is achieved by means of the lifting mechanism installed on the support. The common lifting mechanism types include hydraulic type and mechanical type. The hydraulic type relies on the hydraulic pump to make the hydraulic cylinder extend and retract, so as to accurately and smoothly adjust the height of the formwork and also has the ability to bear heavy loads.

[0004] When the existing large formwork support system is adjusted in height by means of hydraulic or mechanical adjustment, due to the lack of effective locking mechanism, when encountering vibrations and impacts such as strong wind, slight earthquake or other large-scale mechanical operation in the construction site, the formwork support is prone to shaking or even displacement. As a result, when the hydraulic or mechanical mechanism bears the weight of the concrete pouring and other external forces, it often needs to continuously provide a larger force to maintain the position stability of the formwork support, which not only increases the burden of the equipment and leads to increased energy consumption, but also under the long-term high load, the hydraulic system may leak and the mechanical mechanism may be worn or deformed, thereby causing instability of the whole system and easily causing construction safety hazards. Therefore, a mobile lifting locking device for a large formwork support system is provided. CONTENT OF THE INVENTION
