The invention relates to the technical field of hydraulic jack equipment and discloses a magnetorheological fluid-based horizontal jack locking mechanism. The magnetorheological fluid-based horizontaljack locking mechanism comprises a horizontal jack main body; a lifting truss is arranged in the middle of an inner cavity of the horizontal jack main body; a rotating sleeve is arranged inside the lifting truss; and permanent magnet rotating bodies are movably arranged at the two sides of the inner cavity of the rotating sleeve in a sleeving manner. According to the magnetorheological fluid-based horizontal jack locking mechanism, the arrangement of the internal structure of a sliding support block enables the sliding support block to smoothly slide and rub between the inner walls of supportring blocks to support the support ring blocks and parts thereon, and meanwhile, circular through holes are formed in the sliding support block, so that the sliding support block can rotate on the inner walls of the support ring blocks at will under the characteristic that the magnetorheological fluid filled in a support circular ring and a support spindle is not added with a magnetic field to form low viscosity, great resistance influence cannot be caused, and the smoothness of the horizontal jack in lifting or lowering loads is high.

    本发明涉及液压千斤顶设备技术领域,且公开了一种基于磁流变液的卧式千斤顶的锁止机构,包括卧式千斤顶主体,所述卧式千斤顶主体内腔的中部设有抬升桁架,所述抬升桁架的内部设有旋转套筒,所述旋转套筒内腔的两侧均活动套装有永磁转体。该基于磁流变液的卧式千斤顶的锁止机构,对于滑动支撑块内部结构的设置,使其可以流畅的在支撑环块的内壁间滑动摩擦以支撑支撑环块及其上的部件,同时在其内部设有圆形通孔,使得填充在支撑圆环和支撑主轴内部中的磁流变液在未加磁场成低粘度的特性下,滑动支撑块可以随意在支撑环块的内壁上旋转,而不会受到较大的阻力影响,使得该卧式千斤顶在抬升或下方载荷时的流畅性较高。
