Abstract
The utility model discloses a tube threading device. The utility model is provided with a guide rod 1 whose both ends are provided with two guiding heads 2, the guide rod 1 is provided with a front opening and closing body and a back opening and closing body, one of the opening and closing body comprises a front sliding bush 5, a back sliding bush 6, a pressure spring 11, an opening and closing rod 8, an opening and closing rod 10 and a supporting foot 9. The front ends of two opening and closing bodies are respectively provided with a pulley wheel, a guy rope 13 and a guy rope respectively bypasses the front pulley wheel and the back pulley wheel, one of the guy ropes is fixed on the tail section of the opening and closing body, and the other of the guy ropes is fixed on the tail section of the guide rod. When the utility model is used, the user pulls two guy ropes by two hands, one of the hand tenses the guy rope, the other hand loosens the other guy rope, the two opening and closing bodies are first opened and then closed and grip the tube wall, and the guide rod 1 onwards climbs step by step.
Description
The utility model is a kind of pipeline threading device, is used for the threading of subway or the threading of other 90mm pipe warp.
In prior art, pipeline wire rope handling utensil generally all adopts bamboo chip or steel disc and sticking plaster, more original with bamboo chip or steel disc and sticking plaster as the threading mode of threading device, because general cable duct all has more than 100 meter long, therefore, how long pipeline has, how long the bamboo chip of wire rope handling or steel disc must be prepared, and obviously, so Chang bamboo chip or steel disc are regardless of being in operating aspect or carrying, the taking and placing aspect all is very inconvenient, for this reason, some people has also thought various corresponding ways, as roller etc., though from having solved some problems in varying degrees, but all not really desirable, so fail to apply.
The purpose of this utility model is to design a kind of pipeline threading device according to bionics, makes it imitate creeping of insect by means of the pulling force of two stay cords, creeps forward in pipeline.
Solution of the present utility model is as follows: it has a guide rod, and the guide rod two ends are provided with the elastic guide head, is provided with the identical opening and closing body of former and later two structures on guide rod.This opening and closing body has former and later two sliding sleeves that are enclosed within on the guide rod, is with a stage clip between two sliding sleeves, and hinge is joining 3 opening and closing bodies along the circumferential direction uniformly-spaced arranging in the rear end of preceding sliding sleeve, and a support foot is equipped with in the end of each opening and closing body.Also cut with scissors at the back sliding sleeve front end relative with each opening and closing bar of preceding sliding sleeve and to have joined 3 identical opening and closing bars, its end is hinged on the preceding sliding sleeve opening and closing bar relative with it, and described toe-out zoarium is positioned at the first half of guide rod by the fixing pin on the sliding sleeve of back.The relative opposite side of sliding sleeve respectively extends a pulley mount before one side of sliding sleeve and the posttension zoarium before the toe-out zoarium, on these two fixtures a pulley has been installed respectively.This threading device also has two stay cords, and wherein an end of a stay cord is walked around the afterbody that pulley on the toe-out zoarium is fixed on the posttension zoarium, and an end of another root stay cord is walked around the afterbody that pulley on the posttension zoarium is fixed on guide rod.
During use, two pull two stay cords, stretched and relaxed, make the opening and closing successively of two opening and closing bodies, take off tube wall, and the guide rod stepping is pushed ahead.
Describe in detail according to embodiment below.
Accompanying drawing, three-dimensional structure diagram of the present utility model.
Referring to accompanying drawing, the guide head 2 usefulness steel wires at guide rod 1 two ends are made the shell shape, be convenient to penetrate, guide head is fixed on the two ends of guide rod with the fixed cover 3 that has trip bolt, among the figure the 5, the 6th, the forward and backward sliding sleeve the 8, the 10th of opening and closing body, hinge is associated in the opening and closing bar on the forward and backward sliding sleeve, the 9th, support foot adopts rubber wear-resistant material, and the 11st, stage clip plays the opening and closing reset response.The 4th, the fixture of pulley 7.One end of stay cord 13 is walked around on the screw that front wheel 7 is connected on sliding sleeve behind the posttension zoarium, one end of stay cord 14 is walked around on the screw that rear wheel is connected on guide rod afterbody guide head fixed cover, course of action is: threading device is inserted pore, two hands are simultaneously with the accelerative force stay cord 13 and 14 of wrenching, then, the posttension zoarium is subjected to the kick of stay cord simultaneously and opens, support foot is taken off tube wall, at this moment two hands cooperate, at the uniform velocity loosening stay cord 14 when at the uniform velocity straining stay cord 13, then the posttension zoarium closes up and slides into the fit afterbody of toe-out forward, prop up back sliding sleeve 6, and the fit open configuration that keeps of toe-out, at this moment, at the uniform velocity strain stay cord 14 again and at the uniform velocity loosening stay cord 13, then the toe-out zoarium closes up, and then the opening and closing body opens, and its support foot is taken off tube wall, simultaneously, guide rod 1 afterbody is subjected to the traction force of stay cord 14 to drive the toe-out zoarium to push forward, and near the fit tail end of posttension, and then at the uniform velocity strains stay cord 13 and at the uniform velocity loosening stay cord 14 up to the back guide head, and so forth, guide rod is pushed ahead length by length, if in operation process, runs into barrier in the pipeline and wears not past tense, can unclamp stay cord simultaneously by two hands, then two opening and closing bodies all close up, and at this moment, with stay cord threading device are hauled out again.The tube head indication is the direction of advance of threading device among the figure.
The utlity model has simple in structure, do not need to add in addition energy source and power, use and taking and placing and advantage easy to carry, easy to utilize.
