Description
The utility model advances a jar linear electric motors car puller, is used for the decking operation that the mine cage shaft promotes.
Existing linear electric motors car puller can not enter operation in the cage, as domestic ZT type linear electric motors car puller commonly used, car puller is pawled and can only be shifted cage chair rocking arm place onto, thereby can only carry out the tinning operation, promptly can only outside jar, have under the condition of mine car, the outer mine car of jar is pushed in the jar, displace a jar interior mine car.Otherwise can't directly release a jar interior mine car.Finish jar task of unloading, in such cases, can only rely on manually and mine car be ejected cage, prolonged the cage decking time (also having prolonged the lifting stop time), increased number of workers and labour intensity, also increase the insecurity of operation with lever.
The existing simultaneously following defective of linear electric motors car puller ubiquity:
1, existing linear electric motors car puller only connects with a horizontal bearing pin between secondary bar, and secondary bar can only be rotated around horizontal bearing pin, and whole secondary bars then become a rigid body on the car puller service direction.Like this, because secondary bar respectively saves the impossible unanimity of finish size, the flatness error that reaches the car puller track laying increases with length, makes secondary bar the card phenomenon of spraining occur in operational process, has increased running resistance and energy consumption greatly.Simultaneously, because the rigid attachment of bearing pin.In the car puller working process, the joint will be born huge rigid shock continually.Use after two, three months, the pin shaft hole on the secondary bar is promptly dashed to draw by garden shape and is deformed into ellipse garden shape, and then loses efficacy, and maintenance is frequent.
2, the theoretical design gaps between the elementary and secondary push rod of linear electric motors should remain on 2-3mm, and existing linear electric motors car puller, the relative body of rod in the position of its secondary bar upper roller is fixed, because the deviation of each secondary bar axle hole position processing is difficult to guarantee to reach full the requirement in 2-3mm gap in the actual installation.When usually minimum place, gap was for 2mm, maximum clearance had reached 6～7mm, has the uneven situation of each wheel load simultaneously.The unbalance loading wear-out of a bearing is very fast.
