Detailed Description
In an embodiment, referring to the attached drawings, a spring steel wire rope tensioning device comprises a working movable pulley 1, wherein the working movable pulley 1 is connected with a tensioned steel wire rope 2, one end of a working steel wire rope 4 penetrates through the center of the working movable pulley 1 and is fixed by a steel wire rope clamp 3, the other end of the working steel wire rope 4 is wound on a working steel wire rope reel 5, the working steel wire rope reel 5 is fixed on a through shaft 15, the through shaft 15 is movably arranged in a bearing of a bearing seat 19, and the bearing seat 19 is fixed on a bearing support 17; it is characterized in that the bearing support 17 is fixed on two sides of the spring box 8; a pull rod 11 is arranged in the cavity of the spring box 8, a spring seat 20 is fixed at the right end of the pull rod 11, a spring 14 is arranged on the spring seat 20 and the pull rod 11, and a spring pressing plate 13 is movably arranged on the pull rod 11 at the left end of the spring 14; the pull rod 11 passes through a hole on the vertical upper at the left of the spring box 8 and is connected with the tensioning steel wire 9; two threaded holes are formed in the vertical side on the left side of the spring box 8, spring force adjusting screws 12 are screwed into the threaded holes, and the spring force adjusting screws 12 are pressed against a spring pressing plate 13; two guide wheel seats 16 are fixed at the left end of the bottom plate of the spring box 8, a guide wheel shaft 18 is movably arranged at the upper end of each guide wheel seat 16, and a guide wheel 10 is fixed on each guide wheel shaft 18; a fixed pulley 7 is fixed in the middle of the upper cover on the right side of the spring box 8; a tension reel 6 is fixed on the through shaft 15; the tension steel wire rope 9 passes around the guide wheel 10 and the fixed pulley 7, and the other end is fixed on the tension reel 6.
The utility model discloses a working method is: by adjusting the spring force adjusting screw 12, the spring pressure plate 13 is moved, thereby compressing the spring 14. The elasticity that the spring compression produced can promote pull rod 11 to take-up wire rope 9 is driven by pull rod 11, behind take-up wire rope 9 passed through leading wheel 10 and fixed pulley 7, makes take-up reel 6 produce the pivoted moment of torsion, take-up reel 6 links together with logical axle 15 through the key-type connection with work wire rope reel 5, installs on bearing support 17, thereby transmits the moment of torsion for work wire rope reel 5 through leading to axle 15, and then makes work wire rope 4 produce the pulling force. The working steel wire rope 4 is fixed with the working movable pulley 1 by using a steel wire rope clamp 3.
