Anti-loosening and stroke calibration device for actuator of automatic position system for dry quenching

Abstract

An anti-loosening and stroke calibration device for an actuator of an automatic position system for dry quenching includes a clamping arm and a hydraulic cylinder. A trunnion is mounted between that clamping arm and the hydraulic cylinder, one end of the trunnion is hinged to the clamping arm, the other end of the trunnion is provided with a first threaded hole, the hydraulic cylinder is fitted with a piston rod capable of sliding along the length direction thereof, the outer periphery of the top end of the piston rod is provided with a first external thread which is matched with the first threaded hole, the outer periphery of the piston rod on the low end of that first external thread is provided with a second external thread, the direction of rotation of the second external thread is opposite to the direction of rotation of the first external thread, the invention connects the clamping arm with the piston rod through a detachable fastening device which is not cumbersome, the piston rod adopts two kinds of threads with opposite direction of rotation, which can form self-lock at the connecting part, prevent the thread from loosening, make the hydraulic cylinder complete the settingaction accurately, avoid the wrong operation, and prolong the service life of the equipment to the maximum extent under the premise of ensuring the normal operation.

Description

technical field [0001] The invention relates to the technical field of supporting positioning devices for CDQ coke ovens, in particular to an anti-loosening and stroke calibration device for an actuator of a CDQ automatic positioning system. Background technique [0002] CDQ technology is a new energy-saving technology promoted by the state. The existing red coke transportation equipment includes electric locomotives, coke tank trolleys, hoists and automatic positioning systems. Generally, an automatic alignment device driven by hydraulic force is installed outside the track of the coke tank trolley to clamp and position the coke tank trolley. During the use of the actuator of the automatic alignment device, since the clamped whole set of vehicle weighs 200-350 tons, the impact force of the clamping roller is very large when it contacts the vehicle body. After high-frequency use, the hydraulic rod There will be thread loosening between the rod end and the clamping arm. Afte...

AI Technical Summary

Problems solved by technology

During the use of the actuator of the automatic alignment device, since the clamped whole set of vehicle weighs 200-350 tons, the impact force of the clamping roller is very large when it contacts the vehicle body. After high-frequency use, the hydraulic rod There will be thread loosening between the rod end and the clamping arm. After the loosening phenomenon accumulates, the stroke will be inaccurate, which will eventually cause the clamping arm to collide with the equipment frame, and even the clamping arm cannot fully return, resulting in a Vicious accident of collision between coke tank trolleys
