The invention discloses atraction device for the underground assembly of a subway shield tunneling machine. The traction device comprises a first connecting plate and a second connecting plate, a first connecting block is connected into the first connecting plate, a second connecting block is fixedly connected to the outer wall of the second connecting plate, a first groove is formed in the outer wall of the second connecting block, the first connecting block is movably connected into the first groove, a first through hole is formed in the outer wall of the first connecting block, a pull rod is movably connected into the first through hole, a fixing plate is connected to the top of the pull rod, a second groove is formed in the outer wall of the second connecting block, and a moving block is movably connected into the second groove. The problems that when an existing traction device on the market is used for a long time, a pull rod possibly deforms and bends, and consequently the pull rod cannot be inserted or is not stably connected are solved, the service life is long, the damping and buffering performance is high, and the use requirements of people in production and life are met.
本发明公开了一种地铁盾构机下井组装用牵引装置,包括第一连接板和第二连接板,所述第一连接板内连接有第一连接块,所述第二连接板外壁固定连接有第二连接块,所述第二连接块外壁开凿有第一凹槽,所述第一连接块活动连接在第一凹槽内,所述第一连接块外壁开凿有第一通孔,所述第一通孔内活动连接有拉杆,所述拉杆的顶部连接有固定板,所述第二连接块外壁开凿有第二凹槽,所述第二凹槽内活动连接有移动块。本发明解决了目前市场上现有牵引装置在长时间使用时拉杆可能会出现变形和弯曲的现象,导致拉杆插接不上或者连接不稳的现象的问题,使用寿命长,减震缓冲性强,满足了人们在生产生活中的使用需求。
