Zusammenfassung: | The invention discloses a fast tunneling advance support device for a fully mechanized excavation face, which relates to the technical field of coal mining roadway support, and comprises eight groups of driving components, which are arranged in a tunneling roadway and are used for driving the device to carry out movable support on the working face; the first supporting assembly is fixed to the output ends of the four driving assemblies; the second supporting assemblies are fixed to the output ends of the other four sets of driving assemblies, and the driving assemblies are all located at the four corners of the first supporting assembly and the four corners of the second supporting assembly. One ends of the first telescopic cylinders are symmetrically hinged to the inner side of the first supporting assembly, and the other ends of the first telescopic cylinders are hinged to the outer side of the second supporting assembly; one ends of the second telescopic cylinders are symmetrically hinged to the inner side |
