Laser displacement calibration explosion-proof crane

Abstract

The invention discloses a laser displacement calibration explosion-proof crane. The laser displacement calibration explosion-proof crane comprises a crane body and laser calibration equipment; the crane body comprises longitudinal translation rails, a support column, a main beam and a hoisting mechanism; two longitudinal translation rails are provided, and are arranged on the ground in parallel; the support column is vertically connected above the longitudinal translation rails; the lower end of the support column is connected with a stepper motor; an output shaft of the stepper motor is leaded into the longitudinal translation rails; the laser calibration equipment comprises a laser emitter and a laser receiver; the laser receiver is fixedly mounted on the inner side surface of the lowerend of the support column; a PLC and a motor encoder are arranged on the other side wall of the support column; the laser receiver is connected with an input interface of the PLC; and an output end ofthe PLC is connected with the motor encoder. Through the mode, the laser displacement calibration explosion-proof crane can adopt a laser calibration technology to accurately control longitudinal displacement distances.

Description

technical field [0001] The invention relates to the field of explosion-proof cranes, in particular to a laser displacement calibration type explosion-proof crane. Background technique [0002] The bridge crane is a lifting device that is horizontally placed over the workshop, warehouse and stockyard for material lifting. Because its two ends are located on tall concrete pillars or metal supports, it is shaped like a bridge. The bridge frame of the bridge crane runs longitudinally along the tracks laid on the elevated sides on both sides, which can make full use of the space under the bridge frame to lift materials without being affected. It is the most widely used and the largest number of lifting machinery. At present, the displacement accuracy of domestic bridge cranes is low, and it is difficult to accurately control the longitudinal displacement of the crane to an accurately selected point only by bare-handed control, but this problem can be solved by laser calibration ...
