In this programme, cable connector is used for being fixedly connected with cable, pull rope connector is for connecting pull rope, cylinder lies in underground piping, one of them roller is positioned at the lowermost end of cylinder, and contact with the lowermost end of pipeline, the roller of the cylinder left and right sides then with the left and right sides contact internal walls of pipeline, thus make the sliding friction originally between cylinder and pipeline change rolling friction into, significantly reduce the resistance that cylinder advances, when equal quality cable, reduce tractive effort, and then reduce energy consumption; In addition, owing to no longer directly contacting between cylinder with pipeline, but by roller and tube contacts, thus reduce friction noise, also make cylinder substantially without wearing and tearing simultaneously, effectively can extend the useful life of cylinder.On the other hand, flexible pipe, soft cloth and spring form the barrier strip of a variable-width, make barrier strip can be close to the inwall of cable duct all the time, thus avoid the foreign material in cable duct to slip to the back-end from the front end of auxiliary hitch, wearing and tearing are caused to the cable of rear end.
Preferably, described flexible pipe comprises first flexible pipe and second flexible pipe, the corresponding two ends being inserted into second flexible pipe respectively, two ends of first flexible pipe.
Preferably, between described flexible pipe and cylinder, be provided with four springs, and four springs are separately positioned on four Along ent places of flexible pipe.
Preferably, also comprise retracting cylinder, described retracting cylinder is fixed on the outer wall of cylinder, and the straight line at retracting cylinder place and the center line of cylinder crossing, spring housing is connected on retracting cylinder.
Preferably, described cable connector is positioned on the center line of cylinder.
Preferably, described pull rope connector is positioned on the center line of cylinder.
Preferably, the circumference at described four rolling place is positioned at 1/2 place of cylinder.
The utility model has following beneficial effect:
(1) the utility model by arranging four rolling on cylinder, cylinder is when advance, all the time be roller and tube contacts, thus make the sliding friction originally between cylinder and pipeline change rolling friction into, significantly reduce the resistance that cylinder advances, when equal quality cable, reduce tractive effort, and then reduce energy consumption.
(2) the utility model is owing to adding roller, under the effect of roller, no longer directly contacts between cylinder with pipeline, but by roller and tube contacts, thus reduce friction noise, also make cylinder substantially without wearing and tearing simultaneously, effectively can extend the useful life of cylinder.
(3) the utility model is by increasing flexible pipe, soft cloth and spring, form the barrier strip of a variable-width, make barrier strip can be close to the inwall of cable duct all the time, thus avoid the foreign material in cable duct to slip to the back-end from the front end of auxiliary hitch, wearing and tearing are caused to the cable of rear end.
