The rotational angle of slide block, prevents the one or both sides of hydraulic support from all occurring excessive crooked (sliding owing to guiding
Block and guide post and hinged seat are all rotation relations, after wherein a back timber declines, will certainly make two back timbers in
Between draw close, the center of back timber and the center of base can produce a centre-to-centre spacing, and the biggest crooked degree of centre-to-centre spacing is more
High), it is ensured that the stability in the large of this hydraulic support.
Owing to position-limit mechanism includes the limited block that is arranged at the upper and lower both sides of hinged otic placode, guide runner is to limited block
Direction extends and is correspondingly arranged with limited block, thus is limited the rotational angle of guide runner by limited block
System, simple in construction, good limit effect.
Owing to the end of guide runner is provided with curved portions, curved portions is near limited block, thus at work, leads to
Cross the rotational angle coordinating restricted guidance slide block that can not only be good of curved portions and limited block, and can be effective
Stuck phenomenon is occurred to affect the normal problem worked after avoiding limited block to contact with guide runner.
Owing to drive mechanism includes that be respectively arranged on two bases first supports seat, first on two bases
It is provided with hydraulic jack, simple in construction between support seat, it is easy to accomplish, and low cost of manufacture.
During owing to being in mobile status, the piston rod of hydraulic jack is positioned at the inside of sleeve, thus passes through sleeve
Hydraulic jack is protected, substantially increases the service life of hydraulic jack.
Owing to being rotatablely equipped with the roller relying on base on the second support seat, thus in two bases alternately fortune
Time dynamic, by the rotation of roller, reduce frictional force, it is ensured that two bases replace the fairness of movement.
Owing to being equipped with the extensible canopy that the second power set drive in each back timber, thus by extensible canopy not only
Substantially increase supporting scope, and uneven roof timbering is had the strongest adaptability.
