The invention relates to the field of jacks, and discloses an anti-slip mining anchor cable pressurization tensioning jack, which is characterized in that a clamping block is manually clamped by a wrench to rotate, so that a threaded rod at the bottom of a chuck rotates on the inner wall of a threaded column, the chuck moves downwards, the expansion tensioning degree of a pressing plate on an anchor cable is adjusted, and the expansion degree of the anchor cable is ensured; the bottom of the chuck is provided with a threaded rod, the threaded rod of the chuck is in threaded connection with the inner wall of the threaded column, the top of the chuck is fixedly connected with a clamping block, the chuck presses the pressing plate to enable the pressing plate to deform outwards, and the anchor cable is tensioned. Through cooperation of the chuck and the pressing plate, according to vibration of the anchor cable, the pressing plate deforms under limitation of the chuck, the pressing plate buffers the vibrating anchor cable through deformation, impact force of vibration is counteracted, and the situation that due to the fact that the sliding force of the jack is too large, pressurization tensioning of the anchor cable is affected is prevented.

    本发明涉及千斤顶领域,且公开了一种可防打滑的矿用锚索增压张拉千斤顶,人工通过扳手夹紧卡块转动,使卡盘底部的螺纹杆在螺纹柱内壁进行转动,使卡盘下移,调节压板对锚索的扩张拉紧程度,保证对锚索的扩张程度,所述卡盘的底部设置有螺纹杆,所述卡盘的螺纹杆与螺纹柱的内壁螺纹连接,所述卡盘的顶部固定连接有卡块,卡盘压动压板,使压板向外形变,使锚索张紧,在通过千斤顶对锚索进行增压张拉的过程中,锚索出现震动时,通过卡盘与压板的配合,根据锚索的震动,使压板在卡盘的限制下形变,使压板通过形变对震动的锚索进行缓冲,将震动的冲击力进行抵消,防止造成千斤顶滑动的力度过大,影响对锚索的增压张拉。
