The specific embodiment
The utility model is described in further detail below in conjunction with specific embodiments and the drawings, but should not limit protection domain of the present utility model with this.
Referring to figs. 1 to Fig. 6, steel cable length adjustment and the pre-tightening apparatus of the present embodiment comprise: shell 14, hanging screw 16, the first jam nut 41, nut 42, the second jam nut 43, fork-shaped screw rod 44, hydraulic actuating cylinder 18, Hydraulic Pump and compression indicator 17, hang tight nut 19, steel cable 12, connecting panel 13.
Wherein, an end of shell 14 has end cap (not indicating), and the other end and second is connected member 15 and is connected.Second to be connected member 15 can be for example that bearing pin is connected with connection mode between shell 14, but be not limited to this.
Fork-shaped screw rod 44 passes end cap, and the first jam nut 41 is screwed onto on the fork-shaped screw rod 44 in the end cap outside, and nut 42 and the second jam nut 43 are screwed onto on the fork-shaped screw rod 44 of end cap inboard, wherein nut 42 near end cap and the second jam nut 43 away from end cap.
Hanging screw 16 is positioned at shell 14, is spirally connected with fork-shaped screw rod 44.More specifically, the end of fork-shaped screw rod 44 right-hand members can have negative thread, is used for being spirally connected with hanging screw 16.
Hydraulic actuating cylinder 18 is positioned at shell 14, and hanging screw 16 is socketed in the endoporus of hydraulic actuating cylinder 18.Hydraulic Pump is connected with hydraulic actuating cylinder 18 with compression indicator 17.
Hang tight nut 19 and be screwed onto on hanging screw 16, hydraulic actuating cylinder 18 is at the intermediate hsg of shell 14 and hang tight between nut 19.The second jam nut 43 is screwed onto on the fork-shaped screw rod 44 of end cap inboard, hangs tight on the hanging screw 16 that nut 19 is screwed onto hydraulic actuating cylinder 18 opposite sides.
