Description

Technical Field

[0001] The invention relates to the technical field of auxiliary equipment for concrete production, and in particular to a feeding device and equipment for producing lightweight ultra-high performance concrete. Background Art

[0002] Ultra-high performance concrete (UHPC) is an advanced composite cementitious material with excellent workability, mechanical properties and durability. UHPC is used in the pavement layer of steel bridge decks, which can significantly improve the stiffness of steel bridge decks and reduce the risk of fatigue cracking of steel bridge decks and damage to the pavement layer. However, UHPC has an extremely low water-cement ratio and a high powder content, so it still has a series of problems such as heavy weight and high shrinkage. In the context of lightweight, rapid erection and prefabricated production of bridge engineering, lightweight ultra-high performance concrete materials (LUHPC) have a broad application space. Compared with UHPC of the same strength, the bulk density of LUHPC is reduced by 15%-20%, and the shrinkage strain is greatly reduced, which can provide a new choice for the high-strength, lightweight and carbon-reducing design of new bridge structures and the maintenance and reinforcement of existing bridge structures. However, the LUHPC mix ratio is complex and has high quality control requirements. In particular, light and fine aggregates need to be pre-wetted. Otherwise, it will cause large fluctuations in the water-cement ratio of the concrete, easy segregation and stratification, and large loss of expansion over time. At present, there are a series of difficulties in the pretreatment of LUHPC light and fine aggregates, such as the lack of scientific and efficient methods, and unclear mixing and production processes. The use of new pre-wetting tooling equipment can make the pre-wetting of light and fine aggregates more sufficient, the production of LUHPC concrete more efficient, and the quality and performance more stable, promoting the large-scale application of new LUHPC materials. When producing this concrete, a crane is needed to deliver the pre-wetted light and fine aggregates to the mixing host. Therefore, it is necessary to design a flippable clamping device to match the pre-wetting tooling bucket for the production of lightweight ultra-high performance concrete.

[0003] In the prior art, for example, the concrete test block production and feeding and loading device with patent number CN219882784U discloses a concrete test block production and feeding and loading device, including a loading platform respectively provided with a flushing area for flushing the test mold and an oil spraying area for spraying oil on the test mold, a flushing component for flushing the residual concrete debris in the test mold, an oil spraying component for spraying oil on the inner wall of the test mold, a clamping and flipping component for clamping and flipping the test mold, and a control component that outputs control signals to control the actions of each component. Through the above-mentioned structural setting, the cleaning and oil spraying operations after the concrete in the test mold is demolded can be automatically completed without manual intervention, thereby improving the efficiency of the loading preparation process before feeding. Another example is a wheel processing flip hanger with patent number CN205472267U, which includes a clamping part, an auxiliary clamping part and a rotating mechanism. The clamping part includes a hook plate, a short connecting rod, a long connecting rod and a workpiece clamp. The auxiliary clamping part includes a sliding sleeve, a connecting plate and an auxiliary connecting rod. The hook plate, the short connecting rod and the long connecting rod are hingedly connected. The workpiece clamp is connected to the long connecting rod through a rotating mechanism, and the workpiece is clamped by the dead weight of the workpiece. A self-locking mechanism is provided on the rotating mechanism, and the rotation of the workpiece is controlled by the self-locking mechanism. The utility model can automatically open the workpiece clamping port by controlling the driving, and can directly flip the workpiece in the hoisting state. It is easy to use, has high safety performance, and is easy to promote and use.

[0004] However, the structure of the clamping and flipping assembly in the concrete test block production and feeding device is difficult to apply to the crane lifting scenario, and the flipping hoist used for wheel processing is aimed at the lifting of wheels, and it is difficult to clamp the tooling bucket containing pre-wetted light and fine aggregate, which makes it difficult to efficiently feed the light and fine aggregate, affecting production efficiency.

[0034] The embodiments of the present application provide a feeding device and equipment for the production of lightweight ultra-high performance concrete, which can solve the problem that the structure of the clamping and flipping assembly in the feeding and loading device for concrete test block production in the prior art is difficult to be applied to the scenario of crane lifting, and the flipping hoist for wheel processing is aimed at the lifting of wheels, and it is difficult to clamp the tooling bucket containing pre-wetted light and fine aggregate, which has the problem of difficulty in efficiently feeding the light and fine aggregate and affecting production efficiency.

[0035] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 6 As shown, on the one hand, the present application provides a feeding device for producing lightweight ultra-high performance concrete, which comprises:

[0036] The connecting rod mechanism 1 comprises two groups of clamping rods 11 which are rotatably connected in the middle. The upper ends of the clamping rods 11 are used to be connected to the hoisting mechanism.

When the upper end of the clamping rod 11 is lifted by the hoisting mechanism, the lower ends of the two groups of clamping rods 11 are close to each other. When the lower ends of the two groups of clamping rods 11 are close to each other, the two arc-shaped clamping plates are close to each other to be located below the outer edge 42 of the tooling barrel 4. The tooling barrel 4 can be automatically tightened and lifted by the arc-shaped clamping plates abutting against the lower side of the outer edge 42, and continue to be tightened under the action of gravity to clamp the tooling barrel 4. The tipping operation of the tooling barrel 4 can be quickly completed through the driving mechanism 3, thereby improving the efficiency of the feeding operation and solving the problem that the structure of the clamping and flipping assembly in the concrete test block production feeding and waiting device in the prior art is difficult to be applied to the scene of crane lifting. The flip hoist for wheel processing is aimed at the lifting of wheels, and it is difficult to clamp the tooling barrel filled with pre-wetted light and fine aggregates. There is a problem that it is difficult to efficiently feed light and fine aggregates, which affects production efficiency.
