This invention provides a prefabricated building curtain wall and its usage method, including a curtain wall body, a fixing frame, and a support mechanism. The curtain wall body is vertically installed on the periphery of the building and parallel to the periphery. The curtain wall body is fixedly connected to the periphery of the building through four sets of fixing frames. The support mechanism is fixedly connected to the side of the curtain wall body adjacent to the periphery of the building. The curtain wall body includes an installation frame, an installation groove, fixing holes, fixing plates, wall panels, and limiting grooves. The installation groove is opened on the side of the installation frame adjacent to the periphery of the building. The wall panels are installed inside the installation groove. The fixing plates are fixedly connected to the top of the installation groove on the side away from the periphery of the building. The limiting groove is opened at the bottom of the fixing plates. The fixing holes are opened on the side end face of the installation frame. This invention effectively reduces the difficulty of disassembling and assembling the curtain wall panels, while increasing the service life of the curtain wall fixing frame and reducing the maintenance cost of the curtain wall.

The utility model relates to a hoisting machinery technical field especially discloses a portal crane trolley walking mechanism, including balance beam, the upper hinge support is provided at balance beam top, the bottom of balance beam is connected with two trolleys through two lower hinge supports, every trolley is provided with two walking wheels of even distribution, one trolley end part is provided with the support, is provided with the cleaning device on the support, and the cleaning device includes roller brush mechanism and transmission mechanism, and roller brush mechanism is driven connection with walking wheel through transmission mechanism. The utility model discloses the rotation of contact wheel is driven by the friction between walking wheel and contact wheel and transmission to drive roller brush mechanism by adjusting contact wheel and walking wheel contact, realizes the cleaning to the track top surface and both side surfaces through the rotation of first brush roller and second brush roller, need not extra increase power, reduces use cost, and the overall structure is simple, and adjustment is convenient, and roller brush mechanism and transmission mechanism are all installed in the support interior, and will not produce collision damage, and the use safety is high.
