The invention discloses a telescopic boom, which comprises a mounting frame (1), a telescopic outer cylinder (2), a telescopic inner cylinder (3) and a straight line oil cylinder (4), wherein the telescopic outer cylinder (2) is sleeved in the mounting frame (1); the telescopic inner cylinder (3) is sleeved in the telescopic outer cylinder (2); the mounting frame (1) and the telescopic outer cylinder (2) are connected to two ends of the straight line oil cylinder (4) respectively; the telescopic boom also comprises an extending pulley device (5); the extending pulley device (5) comprises a first pulley (51) and a first traction part (52) winding on the first pulley (51); the first pulley (51) is fixedly connected to the front end of the telescopic outer cylinder (2); a fixing end (521) ofthe first traction part is fixedly connected to the mounting frame (1); and a movable end (522) of the first traction part is fixedly connected to the telescopic inner cylinder (3). The telescopic boom has a simple structure, and can provide large extending distance. The invention also discloses a tunnelling and shoring integrated machine with the telescopic boom, which has the same technical effect.
Description
technical field [0001] The invention relates to the technical field of mining machinery, in particular to a telescopic arm for an integrated digging and protecting machine. The present invention also relates to an excavating and protecting integrated machine comprising the above-mentioned telescopic arm. Background technique [0002] With the rapid development of my country's economic construction, mining machinery continues to develop in the direction of mechanization and automation, and comprehensive mechanized coal mining equipment is more and more widely used in coal production under various geological conditions. [0003] The excavation and protection integrated machine is a mining machine that integrates the excavation mechanism and the support mechanism. The excavation mechanism realizes the crushing of coal and rock, loading and transporting, mobilizing and walking through the rotation of the cutting head in the up, down, left and right directions; the support mechan...
