Intelligent sheet releasing machine

Abstract

The intelligent releasing machine comprises an electric control operation table, an electric releasing machine, a guide sleeve, an electric control cable and a pedal switch, the electric releasing machine is electrically connected with the electric control operation table through the electric control cable, and the pedal switch is electrically connected with the electric control operation table. The electric releasing machine comprises a releasing machine body, a servo motor and a sleeve, the servo motor is used for driving the releasing machine body and arranged at the top of the releasing machine body, the sleeve is arranged at the bottom of the releasing machine body, and a multi-stage planet wheel and sun wheel structure is arranged in the releasing machine body. The output rotating speed of the servo motor is reduced layer by layer, so that the rotating speed output by the driving shaft is small, the lower the rotating speed is, the larger the torque is under the condition that the output power is consistent according to mechanical characteristics, and through layer-by-layer multiplication of the torque, the torque conveyed to the tension rod nut through the driving shaft, the sleeve and the guide sleeve is large enough. And therefore, the tensioning rod nut can be smoothly unscrewed.

Description

technical field [0001] The invention relates to the technical field of sleeper construction devices, in particular to an intelligent stretching machine. Background technique [0002] In the prior art, two tension rod nuts B are generally provided on the sleeper A of the railway, and the process of releasing the sleeper is the process of loosening the tension rod nut B. [0003] During the tensioning process of railway prestressed concrete sleepers, the prestressing of steel bars will cause the deformation of the concrete sleepers, which is extremely unfavorable for the sleeper shoulders, and often causes cracks or falling blocks in the shoulders in practice. The sleeper is stretched to eliminate its stress. The traditional stretcher is a hydraulic type, which pushes the piston of the stretcher forward by outputting high-pressure oil, thereby pushing the ratchet to rotate and loosening the nut. However, this form of tool is slow and efficient. Therefore, a new type of sleepe...

Problems solved by technology

[0003] During the tensioning process of railway prestressed concrete sleepers, the prestress of the steel bars will cause the deformation of the concrete sleeper, which is extremely unfavorable to the shoulder of the sleeper. In practice, it often causes cracks or pieces of the shoulder. The sleeper is stretched to eliminate its stress. The traditional tensioning machine is hydraulic, which pushes the piston of the tensioning machine forward through the output of high-pressure oil, thereby pushing the ratchet to rotate and loosen the nut, but this type of tool is slow and efficient. Therefore, a new type of sleeper tensioning machine is designed and developed, which completely subverts the working method of traditional hydraulic tensioning machines and provides a new concept of sleeper stress relaxation.
