Problems solved by technology

Its disadvantages are: waste of steel and laborious construction, poor effect
In general, it takes about ten minutes to probe a 10-meter-long and 16mm-diameter commonly used buried pipe, and the slow one takes several hours, or the probe fails.
[0005]The method of retaining steel wire has a higher success rate of threading, but it wastes steel. At the same time, the existence of steel wire in the pipe makes the handling, bending, The construction links such as pipes are laborious, and it also increases the difficulty of operation for these links
The reserved steel wire is basically discarded after being used up, which is not conducive to material utilization and environmental protection
The empty pipe method saves steel

Embodiment 1

[0051] Since there are many factors that cannot be grasped in advance in the resistance during operation, and it is very troublesome to re-thread the lead wire, so every step of the operation must be fully grasped and redundant, with safety and reliability as the primary consideration, so as not to cause trouble. On the contrary, the gain outweighs the loss. But in any case, if during the operation of a certain step, it is found that the lead wire of the front stage is overwhelmed, then there is no need to be embarrassed, as long as the front line is pulled out from the other end of the wire tube in the opposite direction, that is, the problem can be rediscovered. Going back to the previous state, and then rearranging the loop reinforcement scheme will definitely solve the problem. In addition, for professional threading constructors, the operation of multiple loops to strengthen the lead wire should use a winding tool or machine such as a roulette to speed up the construction...

example 1

[0052] Example 1 The wiring object is a common buried pipe with a length of 10 meters and a diameter of 16mm in a residence. The primary lead wire in the pipe is a thin nylon wire or a polyester wire with a diameter of 0.18mm. After testing, it is found that its tensile strength is only about 1.0kg. Be prepared to wear a soft phone cord. Suggestion: You can first use a high-quality thin nylon wire with a diameter of 0.13mm and a tensile strength of more than 3kg as the secondary lead, and use the guide ring cap as a guide at the inlet pipe, and then pass through the nylon wire with a diameter of 2mm or more. You can try holding the phone line.

example 2

[0053] Example 2 The wiring object is a common buried pipe with a length of 5 meters and a diameter of 16mm in a residence. The primary lead wire in the pipe is a nylon wire with a diameter of 0.5mm. After testing, it is found that its tensile strength is greater than 6kg, and it is a soft telephone line to be worn. Suggestion: You can directly pull the telephone line to try it on. If you feel abnormal in the middle, you can pull out the telephone line from the reverse direction to make the problem return to the previous step. Then, increase the strength of the lead wire in the middle to a nylon wire with a diameter of 2mm or more, and then try it on.

Abstract

The invention discloses a guide ring cap for threading during pipe distribution and a threading method for the guide ring cap. A plurality of clamping slots are uniformly formed on the inner circumferential surface of the guide ring cap along the circumference; guide wheels are arranged in the clamping slots; and the rolling surfaces of the guide wheels protrude from the top surface of the guide ring cap. By a wire-feeding guide ring for threading during pipe distribution, resistance formed by feeding of a wire cable at a pipe opening is reduced greatly; therefore, the wire-feeding speed is increased greatly and a wire cable skin coating layer can be relatively protected to a certain extent, even the possibility that the conventional threading construction required to be finished by two persons is changed into the threading construction finished by only one person is increased.

Description

technical field [0001] The invention relates to threading construction in buried pipes, in particular to a wire feeding guide ring for threading in pipe laying and a threading method using the guide ring. Background technique [0002] The rapid development of my country's information technology has greatly increased the demand for the types and quantities of various wires and cables in families and society. Therefore, in building construction, it is often necessary to bury a large number of wiring pipes in various building structures during the civil construction stage, and then penetrate various cables into the wire pipes when entering the electrical decoration process in the future. The specific method when threading the cable is: firmly connect one end of the lead wire that has passed through the beginning of the wire tube to one end of the cable to be threaded, and then pull the other end of the lead wire from the end of the wire tube to the outside. As the end lead is ...
