(3) half new ring-like pulley groove circle is set on the disc with the electrical pads weldering fixing a little, and then its second half ring-like pulley groove circle is set on the disc two semi-ring type pulley groove circles linked together with anchor clamps, and adjust the angle of pulley groove circle with the detector measurement, make it perpendicular to pulley spindle;
(4) the place solid welding of pulley groove circle piecewise uniform is fixed on the disc, symmetrical then segmentation is freezed, and knocks weld bond with hand hammer, makes it welding stress and disperses, and strengthens gusset in the welding of the bi-side of pulley groove circle and each disc assembling part then;
(5) after the welding of pulley groove circle and disc, anchor clamps are pulled down, and made a call to 45 ° of grooves in the joint, degree of depth 5mm freezes then, and last electricity consumption is started emery wheel weld bond is polished.
Bolton maintenance and installation technology:
(1) makes a complete pulley groove circle, the position of corresponding disc has the clamping plate of through hole in the welding of pulley groove circle both sides, then complete pulley groove circle is cut into two pulley groove circles that semicircle is ring-like, on the inner headed face of two halves circular shape pulley groove circle interface both sides, is shaped on screw then;
(2) cut disc with welding torch exactly along circle in the pulley groove circle that damages, and the pulley groove circle that damages is taken off from the disc cut-out, corresponding pulley groove circle clamping plate lead to the hole site is shaped on through hole on each disc then;
(3) two pulley groove circles that have clamping plate are set in respectively on the disc,, clamping bolt are installed, connecting plate and fastening screw trip bolt are installed by the screw of two halves circular shape pulley groove circle interface by the through hole of clamping plate and disc.
Advantage and good effect that the present invention has are: because the pulley groove circle is made two splicing pulley groove circles that semicircle is ring-like, realize the maintenance and installation of pulley groove circle with the linkage structure of welding or bolton mode, not only solved the problem that pulley need disintegrate boom system of changing, improved manufacturing efficiency, and the wheel hub and the disc part of pulley have been kept, improved the utilization ratio of material, in addition the present invention also have simple in structure, advantage for ease of maintenaince.
