Background
In modern building and installation engineering, threading is inevitably carried out on pipelines, and particularly in the industries of building electrical engineering, industrial installation engineering, intelligent building engineering, municipal engineering, chemical engineering and the like, for example: the metal pipe, the plastic pipe and the composite pipe are used for laying electric wires.
Present threading mode has artifical threading, still has a threading machine threading of popularizing gradually, and the wire of threading machine is mostly metallic conductor at present, and the pliability is poor, and the transmission mode of wire is mostly friction drive's mode, the condition of skidding appears easily after using for a long time to traditional threading machine threading speed receives wire and driven influence, and is not fast, leads to threading efficiency not high.
Meanwhile, the traditional threading machine is deficient in bending performance.
Disclosure of Invention
The invention aims to solve the problems and provides an air blowing type threading structure which is simple and reasonable in structure, air is compressed through an impeller to form air blowing type threading, a lead can quickly penetrate out, the threading efficiency is high, and the bending performance is excellent.
Meanwhile, the wire coil is wound by adopting a winding mode to pull back the lead wire, so that large-torque wire pulling is realized, and the wire pulling efficiency is high.
In order to achieve the purpose, the invention adopts the technical scheme that: the utility model provides an air blowing type threading structure, includes the support body, and the support body includes the impeller cavity of rear end, the spool of front end upside and the wire coil cavity of front end downside, and the impeller intracavity articulates there is the impeller, and the wire coil intracavity is equipped with the drum, and round wire on the drum is worn out in the spool through the opening, and the motor is fixed in on the support body, and acts on impeller and drum simultaneously, all is equipped with one-way bearing in impeller and the drum, and the motor is through being fixed in the support body and being equipped with the one-way bearing of one-way bearing's reduction gear case.
Further, the motor sets up between two parties, and the first one-way bearing of impeller is connected through first belt to one side output, and the second one-way bearing of reduction gear box is connected through the second belt to the opposite side output.
Furthermore, the wire is a high-strength light wire, and a light plug is arranged at the outer connector lug.
Furthermore, the opening is also provided with a guide wheel.
Further, the light end cap is a foam end cap.
In summary, the invention has the following advantages:
the wire threading device is simple and reasonable in structure, air blowing type threading is formed by compressing air through the impeller, a wire can penetrate out quickly, threading efficiency is high, and bending performance is excellent.
Meanwhile, the wire coil is wound by adopting a winding mode to pull back the lead wire, so that large-torque wire pulling is realized, and the wire pulling efficiency is high.
example 1:
an air blowing type threading structure is shown in figure 1 and comprises a frame body 1, wherein the frame body 1 comprises an impeller cavity 11 at the rear end, a wire pipe 12 at the upper side of the front end and a wire coil cavity 13 at the lower side of the front end.
Wherein, articulated in the impeller cavity 11 have impeller 2, and the impeller rotates, and compressed air will possess the air blow-in spool of certain pressure.
Be equipped with drum 3 in the drum chamber 13, the drum possesses the circumference degree of freedom as the storage and the coiling mechanism of wire.
The wire 5 wound on the wire coil 3 passes through the opening 131 and out of the wire tube 12, and the guide wheel 8 is arranged at the opening 131, so that the resistance of the wire in running is reduced, and the threading speed is increased.
The lead 5 is a high-strength light lead, preferably a nylon wire, and a light plug 7 is arranged at the outer connector lug of the lead, the light plug preferably selects a foam plug, so that the lead is a light high-strength lead, is matched with wind pressure bearing and can rapidly advance, has excellent bending performance, and is worthy of being arranged into an umbrella shape and used for improving the threading speed.
The motor 4 is fixed on the frame body 1 and acts on the impeller 2 and the wire coil 3 simultaneously.
In the transmission setting, all be equipped with one-way bearing in impeller 2 and the drum 3, motor 4 is through being fixed in support body 1 and being equipped with the one-way bearing of 6 connection drums 3 of reduction gear of one-way bearing.
In this embodiment, the motor 4 is arranged in the middle between the wire coil and the impeller, the output end of one side is connected with the first one-way bearing 21 of the impeller 2 through the first belt 41, the output end of the other side is connected with the second one-way bearing 62 of the reduction gear box 6 through the second belt 42, and the reduction gear box 6 is connected with the one-way bearing of the wire coil 3.
Further explanation is provided by combining the working mechanism, and in the threading process:
the motor rotates clockwise to drive the first one-way bearing through the first belt, the first one-way bearing acts on the first one-way bearing to drive the impeller, the impeller rotates to compress air and blows out air with large pressure intensity through the pipeline, the plug is inserted into the wire arranging pipeline, the compressed air pushes the plug into the wire arranging pipeline and rapidly advances in the wire arranging pipeline, the plug pulls a lead, the one-way bearing in the wire coil does not act, the wire coil rotates clockwise, the wire coil and the reduction gear box move independently without interference, and therefore the motor of the motor rotates clockwise to achieve a threading function;
in the wire pulling process:
the motor reversal, first one-way bearing inoperative, the impeller irrotational, the one-way bearing of second skin drive, the one-way bearing of second plays this moment, drives the drum through reduction gear, and one-way bearing plays in the drum, and then the anticlockwise hoist of drum is acted as go-between, draws back the wire, realizes the function of acting as go-between.
To sum up, this scheme structure is succinct reasonable, through impeller compressed air, forms the formula threading of blowing, and the wire can wear out fast, and the threading is efficient, and the bending performance is outstanding.
Meanwhile, the wire coil is wound by adopting a winding mode to pull back the lead wire, so that large-torque wire pulling is realized, and the wire pulling efficiency is high.
