Description

TECHNICAL FIELD

[0001] The utility model relates to concrete production auxiliary equipment technical field, concretely relates to a kind of feeding device and equipment for lightweight super high performance concrete production. BACKGROUND

[0002] Ultra-high performance concrete (UHPC) is an advanced composite cementitious material, which has excellent workability, mechanical properties and durability. UHPC applied in steel bridge deck pavement layer can significantly improve the stiffness of steel bridge deck, reduce the risk of fatigue cracking of steel bridge deck and pavement layer damage. But UHPC has a very low water-cement ratio and high powder content, so there are still a series of problems such as high self-weight and high shrinkage. Under the background of bridge engineering towards lightweight, rapid erection and prefabricated production, lightweight ultra-high performance concrete material (LUHPC) has broad application space. Compared with UHPC of the same strength, LUHPC has a 15%-20% reduction in volume weight and a significant reduction in shrinkage strain, which can provide new options for high-strength lightweight carbon reduction design of new bridge structure and maintenance and reinforcement of existing bridge structure. However, the composition of LUHPC mix proportion is complex, and the quality control requirement is high, especially the light fine aggregate needs to be pre-wetted, otherwise it will cause the water-cement ratio of concrete to fluctuate greatly, easy to separate and stratify, and the spread degree loss is large. At present, there is a lack of scientific and efficient method for LUHPC light fine aggregate pretreatment, and the mixing and production process is not clear. A new pre-wetting tool equipment can make the light fine aggregate pre-wetting more sufficient, the LUHPC concrete production more efficient, and the quality and performance more stable, which promotes the large-scale application of LUHPC new material. When producing the concrete, the pre-wetted light fine aggregate needs to be put into the mixing host by using the crane, so a reversible clamping device needs to be designed to cooperate with the pre-wetting tool barrel for the feeding production of lightweight super high performance concrete.

The workpiece is clamped by its own weight. A self-locking mechanism is arranged on the rotating mechanism to control the rotation of the workpiece. The workpiece clamping opening can be automatically opened by controlling the traveling crane. The workpiece can be directly overturned in the lifting state. The appliance is convenient to use, safe and easy to popularize.
