2, the motor and the bistrique that grind bar design in the same side, and mill bar turning cylinder has 1 joint, and turning cylinder is contained in below girder, is fixed by bearing block, and motor is arranged on girder, and driven by motor V-belt drives to rotate and rotates.
3, grind the design of electrical motor of bar in walking dolly one end, mill bar turning cylinder has 1 flexible axle, and flexible axle has bearing block, and bistrique is arranged on the mill bar other end, and motor drives rotating soft axle.
There is different defects in the cement inwall sander structure of above-mentioned three kinds of forms; The cement inwall sander turning cylinder of the first form is many, and turning cylinder concentricity is poor, and grind bar when causing bistrique to rotate and produce vibration and beat, interior mill is of poor quality, and equipment fault is many, and polishing noise is large; The cement inwall sander of the second form can only be polished more than DN800mm ductile iron pipe cement inwall, and noise of polishing is large, and bruting process intermediate cam band is met water and easily skidded, and causes bistrique to be turned round, and causes inwall to polish rough; The mill bar of the cement inwall sander of the third form is short for service life, and grinding force is little, and productivity ratio is low, and polishing noise is little.
Utility model content
Technical problem to be solved in the utility model is to provide ductile iron pipe cement inwall sander, the mill bar of this sander does not have power transmission shaft and driving belt, bistrique is provided with balance weight, and motor straight tape splicing rotary bistrique rotates, more than DN400mm long 6-8 rice ductile iron pipe cement inwall of can polishing.
In order to solve the problems of the technologies described above, the technical solution of the utility model is achieved in that
Ductile iron pipe cement inwall sander, described cement inwall sander comprises gear wheel, support roller, lifting device, mill bar, walking dolly; Support roller movable supporting is at the two ends of cast tube, and the port of cast tube one end is provided with gear wheel, and lifting device, mill bar and walking dolly are arranged on the cast tube other end; Lifting device movable supporting mill bar one end; The mill bar other end is arranged on walking dolly.
Further, described support roller is connected with drive motors;
Further, described mill bar one end is fixedly connected with support bar, support bar is fixedly installed motor, emery wheel grinding-head is arranged on motor, motor can rotating Direct driver emery wheel rotary-grinding, improves grinding drive apparatus concentricity, and mill bar vibration and beating diminishes, equipment fault is few, and polishing noise diminishes;
Further, described emery wheel grinding-head is provided with balance weight, beating of emery wheel rotation can be reduced, inwall is polished more smooth, the uneven defect of no concave-convex;
Further, described lifting device comprises leads support roller, guide post, lifting bracket, hoist cylinder, lifting fixed mount, and lead support roller and be arranged on above lifting bracket, lifting bracket both sides are provided with guide post, hoist cylinder is arranged in lifting fixed mount, and hoist cylinder is flexibly connected with lifting bracket; The cylinder bar of hoist cylinder is flexible drives lifting bracket to rise, decline, and guarantees to grind that emery wheel grinding-head on bar is accurate enters in small-bore ductile iron pipe by leading support roller, and lifting device plays and supports and the effect of guiding mill bar;
Further, described walking dolly comprises little car body, and little lower car body is provided with road wheel, movable motor is connected with road wheel by reductor, movable motor and reductor are arranged on little car body, and mill bar is arranged on above mill bar bracing frame, and mill bar bracing frame is arranged on little vehicle body upper portion; Walking dolly drives the walking of mill bar, controls the speed of travel, regulates mill bar height.
The utility model beneficial effect compared to existing technology:
The utility model polishing noise is little, and equipment fault is few, and production efficiency is high, reliable, and labour intensity is low.Specifically:
1) reasonable in design, mill bar does not have power transmission shaft and belt, and motor straight tape splicing moves sand sand and rotates, and mill bar rotational concentricity is high, and mill bar drives does not exist the problem of turning round.
2) fill emery wheel grinding-head place and be provided with balance weight, emery wheel grinding-head whirling vibration and beat little, reliably, interior mill quality is smooth for smooth running.
3) grind bar design volume little, can to polish more than DN400mm long 6-8 rice ductile iron pipe with a mill bar.
