Description

Technical Field

[0001] The present application relates to the technical field of construction engineering, and in particular to a precast concrete component turning mechanism. Background Art

[0002] Precast concrete components refer to concrete products that are processed and produced in a standardized and mechanized manner in a factory. They are widely used in construction, transportation, water conservancy and other fields, and play an important role in the national economy. Precast concrete components require molding and on-site pouring at the construction site. After molding, a flipping mechanism is needed to turn them over.

[0003] In the patent with the published authorization announcement number CN221564717U, the precast concrete component flipping mechanism includes a bottom frame, a rotating motor and two sets of rotating transmission components are respectively arranged on the bottom frame, a flip steel frame component is arranged between the rotating transmission components, and a large annular chain is arranged on the left and right sides of the flip steel frame component, and the large chain is connected to the rotating transmission component by transmission, and two rows of rollers are arranged inside the flip steel frame component, and the rollers in the upper and lower rows are connected to the conveying motor by transmission through sprockets and chains, and multiple cylinder mounting plates are arranged above the rollers in the upper row, and a downward pressure cylinder is arranged on the cylinder mounting plate, and a downward pressure plate is arranged at the end of the piston rod of the downward pressure cylinder, and the rotating motor and one of the rotating transmission components are connected by transmission through sprockets and chains. The utility model realizes the flipping function of objects of multiple varieties and specifications, can be compatible with objects of multiple specifications and sizes, improves the overall production capacity of the industry, saves capital investment, and also reduces the labor intensity of the industry.

[0004] When the above device is implemented, it is not convenient to lock the equipment after the flip. Since the weight of the flipped object is inconsistent on both sides, the equipment cannot be locked after the flip, causing it to tilt to the heavier side. On the other hand, the existing device cannot clean the dust stuck on both sides of the object in time after the object is flipped, which will cause dust to fly into the eyes of the workers when the concrete components need to be processed and installed for the second time after the flip, affecting the vision and safety during operation. Summary of the invention

[0008] By adopting the above technical solution, the smoothness of the rotating ring when rotating on the inner wall of the arc plate can be improved, thereby ensuring that the rotating ring will not have severe friction with the inner wall of the arc plate during rotation, thereby improving its stability during rotation.

[0023] Beneficial effects of this application: 1. The precast concrete component flipping mechanism can position the outer gear ring by arranging a moving plate and a clamping tooth to avoid inconsistent weights on both sides of the precast concrete component. After the flipping is completed, the heavier side exerts greater pressure on the gears, causing tooth damage, and at the same time avoids the tipping of the device. While the screw is rotating, the driving wheel and the transmission belt can be used to transmit the rotating force to the driven wheel and the rotating rod, thereby driving the fan to rotate and blow off the dust adhered to both sides of the precast concrete component, thereby ensuring that dust will not enter the eyes of subsequent workers when performing secondary processing and installation on the precast concrete component, thereby ensuring the safety of subsequent operations and avoiding dust from entering the eyes to affect the line of sight and then affect subsequent operations.

[0024] 2. The precast concrete component turning mechanism drives the connecting plate and the positioning frame to move downward by driving the cylinder until the bottom of the positioning frame abuts against the top position of the precast concrete component, thereby facilitating the positioning of precast concrete components of different thicknesses and ensuring stability. The rotating ring can be provided to improve the smoothness of the rotating ring when rotating on the inner wall of the arc plate, thereby ensuring that the rotating ring will not have severe friction with the inner wall of the arc plate when rotating, thereby improving its stability during rotation. The roller makes it possible to push the precast concrete component when it needs to be removed without the need to carry it in a small space. BRIEF DESCRIPTION OF THE DRAWINGS
