The invention discloses a cutting device for machining an elevator guide rail. The cutting device comprises machine frames, a cutting mechanism, a compressing mechanism and a conveying mechanism, wherein a workbench is arranged on the machine frames; the conveying mechanism comprises supporting frames, a guide roller and a guide roller motor, wherein the supporting frames are arranged on the workbench, the guide roller is installed on the supporting frames, and the guide roller motor drives the guide roller to rotate; the cutting mechanism comprises a mounting plate which is positioned below the workbench, a cutting lifting hydraulic cylinder is arranged on the mounting plate, a cutting motor is connected to a piston rod of the cutting lifting hydraulic cylinder, an output shaft of the cutting motor is connected to a cutting knife, and an opening allowing the cutting knife to vertically penetrate is formed in the workbench; the compressing mechanism comprises a positioning plate whichis positioned between the supporting frames and the opening, a guide through groove corresponding to the guide roller is formed in the positioning plate, and vertical columns are arranged on the two sides of the guide through groove respectively; and a cross beam is connected between the vertical columns, a compressing lifting air cylinder is arranged at the top of the cross beam, and a piston rodof the compressing lifting air cylinder penetrates through the cross beam and is connected to a compressing block. According to the cutting device for machining the elevator guide rail, the elevatorguide rail can be effectively cut.
Description
Technical field [0001] The invention relates to a cutting device for processing elevator guide rails. Background technique [0002] The elevator guide rail is a safe rail for the elevator to travel up and down in the hoistway. The guide rail is installed on the hoistway wall and fixedly connected to the hoistway wall by the guide rail bracket. The guide rail commonly used in elevators is a "T"-shaped guide rail. Features such as strong rigidity, high reliability, safety and low cost. The guide rail plane must be smooth, without obvious uneven surface. Since the guide rail is the shuttle rail of the guide shoe and the safety gear on the elevator car, the clearance must be ensured during installation. At the same time, the guide rail has to bear the responsibility of stopping the elevator when the elevator has an overspeed accident, so its rigidity cannot be ignored. Elevator guide rails often need to be cut during the machining process. The existing cutting devices are complic...
