Abstract
The utility model relates to a high-lift electric block for controlling a claw of a stacker-reclaimer, which is mainly used to open pit coal mines and associated stacking-reclaiming projects and suitable for extremely low temperature severe environments. The technical scheme is that a motor drives a reducer to move at a constant temperature and transfers movement to a coiling block through a central shaft so as to drive two steel wire ropes to move reversely along the coiling block. In the rope winding process, the steel wire ropes are prevented from sliding through a rope pressing assembly. In the layer-changing and winding process, a roll shaft compresses the steel wire ropes to the coiling block through pull of a spring so as to prevent disorder or knotting of ropes. Fast and slow speed regulation can be realized by a variable frequency and variable speed motor with a brake function, and meanwhile the brake safety is ensured. An angle coder sets a pre-depth according to a predetermined command to detect and control the rotating angle of the coiling block, and controls the lifting amplitude of the claw by the steel wire ropes. When a temperature controller displays that the temperature is over-low, a heating device is started first. When the temperature detected rises to the set temperature, the heating device is automatically powered off, and the motor is started to drive the reducer to move, and the electric block works normally.

The specific embodiment:
At normal temperatures direct motor drive retarder motion, retarder passes motion to reel by center shaft, the realization reel rotates, thereby it is oppositely mobile along reel to drive two steel ropes, prevent steel cable sliding by pressure rope assembly in the wiring process, change layer, in the winding process, thereby pressure roller shaft by the pulling force of spring steel rope is pressed to reel and prevents disorder cable or knotting, guarantee the orderly winding of steel rope.Adopt the frequency-conversion and speed-regulation motor of band brake function can adjust rotating speed, thereby reach the speed of control steel rope, realize fast, slow speed governing, guarantee simultaneously brake safe.The angular encoder that is installed in the reel end sets in advance by the instruction of presetting that the degree of depth detects and control the reel anglec of rotation, controls the claw heave amplitude by steel rope.
When the temperature controller displays temperature is crossed when low, the heating arrangement on the first actuating motor stator, when the detected temperatures of sensor rises to set temperature, the heating arrangement auto-breaking, motor start-up drives the retarder motion, and electric block enters normal operation.
