Description

Technical Field

[0001] The utility model relates to the technical field of cable production, in particular to an anti-custody mechanism for continuous cable production. Background Art

[0002] The main function of the cable sheath is to seal the cable in the sheath to protect the cable from the external environment and prevent the wires in the cable from being exposed to the air, thereby extending the service life of the cable. The cable sheath is formed by vulcanizing and wrapping the cable core during the routing process of the upper sealed telescopic tube and the vulcanized tube. The vulcanized tube structure of the prior art includes 01, 02, 03 and 04, 01 is inserted into the front end of 02, the rear end of 02 is connected to 04 through 03, 03 is a concentric reducer, and the cable core is dragged in 01, 02, 03 and 04.

[0003] In the continuous production of cables, parking custody problems and custody problems during normal production wiring often occur. Custody refers to the outer wall of the cable vulcanized tube being rubbed before hardening, forming corrugated scratches.

[0004] After repeated on-site wiring simulations, it was found that Figure 1 As shown in the figure (the dot-dashed line in the figure indicates the cable routing position), when the prior art produces 50 cubic meter cables, the upper sealed telescopic tube and the vulcanized tube are connected by a 426 to 219 concentric reducer, and a step will appear at the transition. When the car is parked and in normal production, the bottom of the cable will contact the bottom of the inner side of the vulcanized tube, causing the bottom of the cable sheath to rub against the bottom inner wall of the sulfur tube, thereby generating a trusteeship. The cable lead segment generated by the trusteeship needs to be cut off, resulting in a waste of production materials, increasing the cable cost and the labor intensity of workers, and reducing production efficiency. Utility Model Content

[0005] In order to solve the above technical problems, the utility model provides a cable continuous production anti-custody system which solves the cable custody problem by increasing the routing height of the cable in the vulcanized tube.

[0006] The utility model discloses a cable continuous production anti-trusteeship mechanism, comprising a telescopic tube, a telescopic outer sleeve, a concentric reducer and a vulcanized pipe, wherein the telescopic tube is inserted into the front end of the telescopic outer sleeve, and the rear end of the telescopic outer sleeve is passed through the concentric reducer, the concentric reducer is a concentric reducer, and the diameter of the telescopic outer sleeve is larger than the diameter of the vulcanized pipe; the utility model also comprises a transition pipe fitting, one end of the transition pipe fitting is connected to the small end of the concentric reducer, and the other end of the transition pipe fitting is connected to the input port of the vulcanized pipe, the two ends of the transition pipe fitting are eccentrically arranged, the transition pipe fitting makes the center line of the vulcanized pipe move down, and the cable core is dragged in the telescopic tube, the telescopic outer sleeve, the concentric reducer, the vulcanized pipe and the transition pipe fitting; by adding the transition pipe fitting, the connection between the telescopic outer sleeve and the vulcanized pipe is realized by concentricity and adopting two-stage transition of concentric reducer and eccentric reducer. The cable sheath is designed to reduce the step, so that the inner bottom of the telescopic outer sleeve and the vulcanized pipe roughly form a plane, and the center line of the vulcanized pipe is moved down to ensure that the cable and the inner wall of the vulcanized pipe maintain a certain distance, so that the bottom of the cable will not contact the inner bottom of the vulcanized pipe during parking and normal production, and the friction between the bottom of the cable sheath and the bottom inner wall of the sulfur pipe is reduced, which completely solves the parking custody and cable custody problems that often occur, and completely solves the waste of production materials caused by cutting the lead wire every time the car is parked, reduces the cable cost, reduces the labor intensity of workers, and improves production efficiency; at the same time, when cutting the lead wire, in order to prevent steam and moisture from entering the cable joint, the cable joint needs to be tightly bundled, and the tight binding also prevents the internal gas of the cable from being released through the core, which is easy to cause cable bubbling and bursting. After the improvement, the risk of bubbling and bursting of the above-mentioned cables is reduced.

[0007] Preferably, the transition pipe fitting is an eccentric reducer, the large head of the eccentric reducer is connected to the small head of the concentric reducer, the small head of the eccentric reducer is connected to the input port of the vulcanization pipe, the center of the small head of the eccentric reducer is lower than the center of the large head, so that the center line of the vulcanization pipe is moved down, and the outer wall of the small head of the eccentric reducer is not lower than the inner wall of the small head of the concentric reducer.

[0008] Preferably, the outer diameter of the telescopic outer sleeve is 426MM, the outer diameter of the vulcanization pipe is 219MM, and the centerline downward movement distance of the vulcanization pipe is 58MM; the above arrangement ensures that when 50 cubic meter cables are produced, there is a certain distance between the cables and the inner wall of the vulcanization pipe, which has good practicality.

[0009] Preferably, the axial length of the concentric reducer is 230MM, and the axial length of the transition pipe is 200MM; the above arrangement is matched with the pipeline position before the transformation, thereby reducing the workload of the transformation.

[0010] Preferably, it also includes flange 1, and flange 1 is arranged at the input end of the telescopic tube; by arranging flange 1, it is convenient to connect the telescopic tube with the upper pipeline.

[0011] Preferably, the connection between the telescopic outer sleeve and the concentric reducer is welded, and the connection between the concentric reducer and the transition pipe is welded.

[0012] Preferably, it also includes flange 2, and the small end of the transition pipe and the input end of the vulcanization pipe are connected through flange 2; by providing flange 2, the disassembly and assembly of the vulcanization pipe and the transition pipe are facilitated.

[0013] Preferably, the telescopic tube, the telescopic outer sleeve, the concentric reducer, the vulcanized pipe, the transition pipe, the flange one and the flange two are all made of stainless steel.

[0014] Compared with the prior art, the beneficial effects of the utility model are as follows: by adding a transition pipe, the center line of the vulcanized tube is moved down, ensuring that a certain distance is maintained between the cable and the inner wall of the vulcanized tube, reducing the friction between the bottom of the cable sheath and the bottom inner wall of the sulfur tube, and completely solving the parking trusteeship and cable trusteeship problems that often occur, and completely solving the waste of production materials caused by cutting the lead wire every time the car is parked, reducing the cable cost, reducing the labor intensity of workers, and improving production efficiency; at the same time, when cutting the lead wire, in order to prevent steam and moisture from entering the cable joint, the cable joint needs to be tightly bundled, and the tight binding also prevents the gas inside the cable from being released through the wire core, which can easily cause cable bubbling and bursting. After the improvement, the risk of bubbling and bursting of the above-mentioned cables is reduced. BRIEF DESCRIPTION OF THE DRAWINGS
