[0067] Example 3
[0068] The above-mentioned rotary adjustable hoisting device structure for the installation of airport road panels can be used for the precise lifting of prefabricated road panels. During lifting, the up and down movement of the lifting mechanism adopts an electric proportional valve to control the push and pull of the cylinder. The up and down movement positioning of the lifting mechanism adopts a magnetic grid connected in parallel with the cylinder. The lifting hydraulic cylinder assembly is controlled by the electric proportional valve on the hydraulic pipeline for overall lifting and lowering.
[0069] The relative rotation of the upper and lower layers of the lifting mechanism is very important for the gap adjustment of the longitudinal and transverse joints of the concrete slab. It is driven by a servo push rod to achieve precise micro-motion control. (It can also be driven by a hydraulic servo cylinder to achieve precise angle control). The rotation angle of the upper layer of the lifting device is detected by a rotation angle sensor, which uses a high-precision absolute encoder for detection.
[0070] The first steering bearing rod assembly and the lifting positioning plate are the lifting points. When the lifting points are connected to the lifting screw member 102 , they must first be accurately aligned (precise positioning solution or manual alignment). When the lifting points go down, check whether they are pressed on the lifting screw member 102 .
[0071] The lifting positioning plate is provided with a displacement sensor locator. The displacement sensor locator performs detection. After the lifting positioning plate is lowered into position, the first rotating electromagnetic hydraulic cylinder assembly extends or contracts, and drives the lifting positioning plate to rotate through the first steering bearing rod assembly. The cement board can be lifted only after the lifting positioning plate is rotated into position, thereby ensuring the reliability of the lifting point buckle.
[0072] The above-mentioned rotary adjustable hanger structure for installing airport road panels has a novel overall structure, is simple and convenient to assemble, is convenient to use for installing concrete road panels, and has high safety and good stability.
