Tight installation mechanism has reached the diameter that is applicable to different kinds of cables and all can carry out the unwrapping wire operation through setting up, and the control cable conductor of being convenient for passes flight 2, drives the pressure of pressure regulation chamber 34 inside and controls the cable conductor installation and press from both sides tightly, makes it be located the axle center department of flight 2, avoids the inner wall contact with cable spool 1 when carrying, simple structure convenient operation, and the fixed effect of carrying on of cable conductor installation of being convenient for.

The working principle is as follows: firstly, taking a wire end of a cable wound on the surface of a paying-off wheel and inserting the wire end into the spiral sheet 2, connecting the wire end with one end of an air inlet pipe 35 through an air inlet end of an air pump, closing an electromagnetic valve 37 on the surface of an air outlet pipe 36, opening the electromagnetic valve 37 on the surface of the air inlet pipe 35, filling air pressure into a clamping ring 31 through the air pump, continuously increasing the air pressure in a pressure adjusting cavity 34, pushing a pressure plug 310 to slide inwards when the pressure is greater than the tensile force of a tension spring 312, simultaneously driving a plurality of clamping rods 38 to move inwards, and controlling a plurality of silica gel pads 39 to extrude the arc surface of the cable to be fixedly installed;

step two, after the cable is installed and locked, closing the electromagnetic valve 37 of the air inlet pipe 35, pulling out an air pipe connected with the air inlet pipe 35, taking the spiral piece 2 and placing the spiral piece inside the cable conduit 1, and when the spiral piece is placed, pushing the telescopic adjusting rod 23 to drive the limiting block 24 to extrude the spring 22 inside, so that the telescopic adjusting rod 23 moves inwards, and controlling the plurality of active friction blocks 28 and the plurality of driven friction blocks 214 to extrude the inner wall of the cable conduit 1;

step three, controlling the driving motor 210 to work, wherein the driving motor 210 rotates to drive the driving shaft 26 to rotate, so as to drive the driving wheel 27 to rotate, the driving wheel 27 rotates to drive the driving friction block 28 on the surface to rotate, the surface of the driving friction block 28 is controlled by the elastic force generated by the spring 22 to extrude the inner wall of the cable tube 1 to generate friction force, and the driving wheel 27 rotates to drive the spiral sheet 2 to perform spiral inward movement conveying on the inner wall of the cable tube 1 under the condition of the friction force, so as to drive the clamped cable to move inwards for paying off;

and step four, when the spiral sheet 2 moves forwards to the outlet end, controlling the driving motor 210 to stop working, controlling the electromagnetic valve 37 of the air outlet pipe 36 to be opened, so that the air pressure in the clamping ring 31 flows out and is reduced, pulling the pressure plug 310 to move backwards, driving the plurality of clamping rods 38 to retract and reset at the same time by virtue of the driven action, leaving the surface of the cable, enabling the cable pad to be in a contact clamping state, and pulling out the spiral sheet 2 to be detached.

The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art should be considered to be within the technical scope of the present invention, and the technical solutions and the inventive concepts thereof according to the present invention should be equivalent or changed within the scope of the present invention.
