The invention discloses a press machine provided with double moving working tables and a moving control device and a control method. The press machine comprises two guide rails, two working tables, a controller, two rotary encoders with bus interfaces, and two bus cables. The two guide rails are parallel to each other, and the length of the two guide rails are the same. The controller is used for controlling the two working tables to move. The two working tables are arranged on the two parallel guide rails in a front-back mode and are guided by the two parallel guide rails. The rotary encoders are additionally arranged on the working tables and are used for detecting the real-time positions of the working tables. Through utilization of data sampling and comparing functions, automatic deceleration and in-place stopping of the working tables are achieved, and the anti-collision function of the working tables is also achieved. The rotary encoders are connected with other networking devices through advanced field buses so as to enable the data sampling to be faster. The press machine enables automatic operation of the moving working tables to have an optimized design scheme, and builds a solid foundation for automatic die changing of the mechanical press machine. The invention further discloses the control device and the control method of the double moving working tables of the press machine.

The invention relates to a real-time monitoring and positioning system of a cable crane. The system comprises a cable crane lifting hook, wherein a positioning host, a power module and a positioning antenna for receiving a satellite positioning signal are fixedly arranged on the cable crane lifting hook; the power module and the positioning antenna are connected with the positioning host in a wired manner respectively; the positioning host is wirelessly connected with a remote server. According to the system, accurate three-dimensional coordinate information and three-dimensional speed of the cable crane lifting hook can be obtained in real time to help construction managerial personnel control concrete construction quality and safety so as to effectively avoid non-standard construction behaviors; in addition, obtained data can serve as a basis of a cable crane construction behavior monitoring solution, so that a cable crane anti-collision function is further achieved, and related information such as the cable crane running efficiency, a cable crane unloading point and whether the spreading and vibrating construction is standard can be obtained, the construction efficiency and construction intensity are remarkably improved, and the duration of a project is shortened.

An ice-breaking and snow-melting cleaning robot for a medium and low speed maglev, comprising a rack (11), folding bending mechanisms, an ice-melting and cleaning mechanism, and an autonomous cruise module (7). The rack (11) spans between two F rails of a low and medium speed maglev to be detected. There are two groups of folding bending mechanisms, which are disposed at two ends of the rack (11) respectively and are located above the F rails. Each group of folding bending mechanisms is provided with a walking wheel pair (5) and a detent wheel pair (2). The snow-melting and cleaning mechanism comprises a fixing frame (15), an F rail obstacle-removal and cleaning unit (14), and an ice-melting heating unit (16). The fixing frame (15) is mounted on the rack (11), located above the folding bending mechanisms, and deployed along the extension direction of the F rails. The F rail obstacle-removal and cleaning unit (14) and the ice-melting heating unit (16) are disposed at two ends of the fixing frame (15) respectively. The autonomous cruise module (7) is mounted below the rack (11). The cleaning robot can melt and clean ice and snow on the F rails, and is simple in structure and convenient to operate.
