The embodiment of the invention provides a pushing type jack for a coal mining system and the coal mining system. The push type jack for the coal mining system comprises a cylinder body, a piston assembly, a light transmitting part, a hydraulic system, a laser distance measuring sensor and a reflecting plate. The cylinder body comprises a bottom and a barrel body part, the matching cavity comprises a hydraulic cavity, a containing cavity is formed in the bottom, the light-transmitting part is arranged in the containing cavity so as to form a containing cavity section separated from the hydraulic cavity, and the hydraulic system is communicated with the hydraulic cavity so as to drive the piston assembly to move in the axial direction of the cylinder body; one of the laser distance measuring sensor and the reflecting plate is arranged in the containing cavity section, the other one of the laser distance measuring sensor and the reflecting plate is arranged on the piston assembly, and the laser distance measuring sensor and the reflecting plate are oppositely arranged so that the movement stroke of the piston assembly can be measured. Therefore, the push type jack for the coal mining system has the advantages of being good in anti-jamming capability and high in stroke measurement accuracy and accuracy.

    本发明的实施例提出一种用于采煤系统的推移式千斤顶和采煤系统。其中,所述用于采煤系统的推移式千斤顶包括缸体、活塞组件、透光件、液压系统、激光测距传感器和反射板。所述缸体包括底部和筒体部,配合腔包括液压腔,底部设有容置腔,透光件设置在容置腔内以便形成与液压腔隔开的容置腔段,液压系统与液压腔连通以便驱动活塞组件沿缸体的轴向移动,激光测距传感器和反射板中的一者设置在容置腔段内,激光测距传感器和反射板中的另一者设置在活塞组件上,激光测距传感器和反射板相对设置以便形成测定活塞组件的移动行程。因此,根据本发明的实施例的用于采煤系统的推移式千斤顶具有抗干扰能力好及行程测定的准确性高和准确性高的优点。
