1. an inspection shaft wire pulling rack, feature is:

  • structure is connected to form by the framework (1,2,3) of three the door fonts in upper, middle and lower;

    Wherein;

    the maximum width of middle frame (2) is less than the diameter of catch pit port, so that be placed in inspection shaft by wire pulling rack;

    Two vertical edges (4) of three, upper, middle and lower framework (1,2,3) are made with pipe, the vertical edge (4) of upper and lower framework (1,3) can be sleeved in the pipe of vertical edge (4) of middle frame (2), and can twitch back and forth in the vertical edge of middle frame (2) (4);

    Upper, middle frame (1,2) are respectively equipped with upper and lower two cylinders (5,6), upper and lower cylinder (5,6) is one section of thick-walled tube, and upper and lower cylinder (5,6) is fixed on separately by upper and lower drum shaft (7,8), between the vertical edge (4) of middle frame (1,2);

    Upper and lower cylinder (5,6) can at the upper flexible rotating of upper and lower drum shaft (7,8);

    Be provided with some roads on two vertical edge (4) tops of middle frame (2) and support (9), supporting (9) is side or the pipe that a length of tape has radian, support two vertical edges (4) of (9) and middle frame (2) not at grade, bending support (9) is greater than the diameter of signal line with the projected gap up and down of bottom roll (6), and when guaranteeing bracing wire with this, circuit can not come in contact friction with support (9);

    Middle frame (2) after being connected and fixed with support (9), bottom roll axle (8) is rectangular frame;

    Gap between the two ends of upper and lower cylinder (5,6) and upper, middle frame (1,2) is less than the diameter of signal wire (SW), in case be stuck in this gap during bracing wire;

    Below middle frame (2), be provided with underframe (3), underframe (3) is connected to form by a crossbeam (13) is vertical with two vertical edges (4), and crossbeam (13) and vertical edge (4) are at grade;

    Underframe (3---in propping up, upper frame (2,1);

    Middle frame (2) is provided with upper and lower set pin (10,11), for the relative position of fixing upper, middle and lower framework (1,2,3);

    Upper and lower set pin (10,11) adopts spiral positioning pin, be made up of bolt (12) and nut, its nut is fixed on the eye of middle frame (2), and time inward turning bolt (12), its bolt can be pressed on the vertical edge (4) of upper and lower framework (1,3) respectively.
