6results about How to "Realize positioning work" patented technology

The utility model provides a sprayed concrete sample preparation tool, which relates to the field of sample preparation tools, and comprises a rack, a driving device mounted on the side wall of the rack, four cutting wheels detachably connected to the driving device, a moving device mounted at the top of the rack, and a rotating device mounted at the moving end of the moving device, a rotating plate is installed at the rotating end of the rotating device, a fixing frame is fixedly connected to the rotating plate through a support, two cutting grooves are transversely formed in the top of the fixing frame, four cutting grooves are longitudinally formed in the top of the fixing frame, and two cutting holes are formed in each of the two transverse side walls of the fixing frame; two cutting holes are formed in the side wall of the fixing frame, guide holes are formed in three plate bodies, separated by the two cutting holes, of the side wall of the fixing frame, pressing frames are movably inserted into the guide holes in a penetrating mode, and a pressing device is installed below the fixing frame. And the operation is relatively convenient.

This invention discloses an automatic positioning and walking device and method for overhead cranes used in automated pole changing. The automatic positioning and walking device for overhead cranes in automated pole changing includes a mounting frame. Mounting frames are installed between the two sides of the trolley moving structure and the moving slide rails. The mounting frames are equipped with drive wheel rotation devices that are driven and cooperate with the moving slide rails. The mounting frames also include a positioning structure and a calibration structure. Multiple calibration structures are equidistantly arranged on the workshop wall. A laser positioning component corresponding to the position of the calibration structure is installed at the top of the mounting frame. The laser positioning component performs multi-angle positioning with the calibration structure to modify the movement position data of the trolley moving structure within the positioning structure. This invention solves the problem in the prior art where the positioning of the trolley moving structure is inaccurate during start-up and shutdown operations, and where there is insufficient time to correct the deviation when sequentially replacing two closely spaced residual poles using the positioning correction structure.
