ZY-3型支架和英國(guó)道梯公司的垛式支架）。</p><p><img src="http://whitemicrobikini.com/skin/b2b/image/lazy.gif" class="lazy" original="http://image.007swz.com/2022/04-22/826066432.jpg" title="826066432.jpg" alt="826066432.jpg"/></p><p>為了提高移架力，歸納起來(lái)可采取下列措施：</p><p>1）采用推移框架，只是臂桿短一個(gè)缸的長(zhǎng)度。</p><p>2）在 Q液壓支架推移千斤頂?shù)?油路上接入一個(gè)交替單向閥。在推溜時(shí)，千斤頂成差動(dòng)油缸。這種方法僅使推力小于移架力，而實(shí)際推溜力和移架力都偏低，如 ZY-3 型支撐式支架。</p><p>3）采用浮動(dòng)活塞推溜時(shí)，活塞腔進(jìn)液，先將浮動(dòng)活塞推到缸口，然后活塞桿采移動(dòng)而推溜。當(dāng)活塞腔進(jìn)液時(shí)，先將浮動(dòng)活塞推向到活塞桿端，然后缸體移動(dòng)移架。因活塞桿面積小于缸體環(huán)形面積，所以移架力大于推溜力。</p><table
