本文提出液压支架的运动轨迹应采用单向前倾斜的轨迹,当支架在顶板压力作用下,支架下降时,水平力指向老塘,支架台力作用线在底座的后部,使支架有较好的稳定性,有利于顶板管理,有利于主要构件的设计,减轻支架的重量。文章指出,要注意处理影响运动轨迹的有关因素,如四连杆机构有关部件铰接点的孔轴配合间隙不宜过大,要选用适当公差来补偿孔轴配合间隙引起的偏移量。 This paper proposes that the movement path of the hydraulic support should adopt the track with one-way forward inclination. When the support is under the pressure of the top plate, the horizontal force points to the old pond when the support descends, and the action force of the support force at the back of the support makes the support better The stability is conducive to the roof management, is conducive to the design of the main components to reduce the weight of the stent. The article points out that pay attention to dealing with the factors that affect the trajectory, such as the four-bar linkage parts of the hinge axis of the hole with the gap should not be too large, to choose appropriate tolerances to compensate for the offset caused by the hole with the gap.
