FACILITY FOR LAYING WALLS OF BRICKS Russian patent published in 1995 - IPC

FIELD: civil engineering. SUBSTANCE: facility includes a chassis with telescopic column and carrying cantilever installed on the column. Device to supply brick in the form of multi-link manipulator and guide frame are installed on the cantilever. The frame may be moved along the cantilever and turned about vertical axis. A device for orientation and feeding bricks is installed on the guide frame. The device may be moved along the frame and turned about vertical axis. The device has concentric guides and movable feeding tube of rectangular cross section. Co-axial hydraulic cylinder is placed in the guide tube. Rectangular pusher is secured on the rod of the hydraulic cylinder. The pusher is placed in cavity of feeding tube and may be moved crosswise. Two inclined roller conveyors are secured to the external surface of the guide tube. Rotary rests are fixed on the internal surface of the guide tube. Cams are fixed on external surface of feeding tube. The cams interact with rotary rests. Feeding tube has charging apertures and sharped lower edge. Spring loaded rollers are installed on two adjacent sides of the feeding tube. A clamp for bricks connected to counterbalance through flexible puller is installed on free end of multi-link manipulator. Hollow sleeves are used to connect manipulator links. Flexible puller is passed through the sleeves and pulleys secured to link ends. A stopper interact with one manipulator link through a spring. The stopper is fixed on the flexible puller. Guide frame has movable counterbalance installed. Flexible puller is used to connect the cantilever with device for orienting and laying bricks. The chassis has tilting wheels and tilting extensible supports. EFFECT: high effectiveness. 2 cl, 10 dwg
