Description

Blower adapter for cable trough device {A BLOW ADAPTOR}

The present invention relates to a blower adapter for a cable trough device, and more particularly, to a blower adapter that can be selectively applied to a cable conduit having a diameter of various sizes, the blowing pressure is strong, easy to pass through the tether line.

When cables and communication cables are exposed to the ground, it is an obstacle to the safety and traffic of pedestrians. Therefore, most cables are laid underground in the cable pipes connecting the manholes in each section. A device for penetrating a cable through the conduit is a cable through device.

The cable trough device is generally the same in configuration and configuration for the purpose of working the cable through the line, but only a slight difference in the time and work efficiency of the trough work. That is, the configuration of the cable trough device includes a blower, a blower adapter for blowing high pressure air generated by the blower into the conduit, a line bullet that is advanced by air pressure in the conduit, and suspended in the line bullet. The work method consists of putting the barrel bullet connected to the barrel into the pipeline and pushing it through the air under high pressure, and then pulling the cable tied to the barrel from the opposite manhole so that the cable can penetrate the pipeline. will be.

Therefore, the most important factor for the cable operation of the cable cable system is the blower adapter (ADAPTOR, induction pipe) for blowing the high-pressure air generated from the blower to the pipe with little loss.

8 and 9 illustrate a blower adapter of a conventional cable carrying apparatus, and a conventional blower adapter has a structure in which the diameter of the cap portion can be applied to only one type of pipe. In other words, in order to use the cable pipes having various diameters according to the type and type of cable, the air blower adapter should be used to match the diameter of each cable pipe. It was to have a cumbersome closed end which exchanges and uses the blower adapter which has a cap part.

In addition, the conventional blower adapter 100 is blown through the blower hose since the blower hose connecting portion 110 is formed at the bottom of the cap portion 140, so that the blower hose connecting portion 110 and the cap 140 is coupled in a bent state. Air of high pressure flowing from the device hits the inner top wall of the cap 140, the blowing pressure is lost as impact energy, the impacted air is rather connected in a straight line with the cap 140, a sealed line The vortex is formed inside the insertion tube 120, so that smooth air flow is not achieved, and thus the air flow efficiency is significantly reduced.

In addition, as shown in FIG. 8, in the conventional line insertion tube 30 formed in the conventional blower adapter 100, a blocking plate 122 is formed in a state where only the through hole 121 is perforated, and is rotated on the blocking plate 122. The valve plate 130 coupled so as to have a small diameter through-hole through-hole 132 that can pass only through the through-line (D) and a through-hole through-hole of the large diameter through which the knot of the through-line can pass (132a) This is perforated separately.

However, as described above, drilling a small diameter through-through line 132 and a large diameter through-through line 132a separately uses a small-diameter through-through line through holes to reduce air leakage. When caught by a small diameter through-hole, the knot will be replaced by a large diameter through-through hole. However, conventional blower adapters formed by drilling small diameter through-holes and large diameter through-holes separately have to stop the blowing operation each time a knot occurs, pass the knot, and then continue the blowing operation again. To have.

Therefore, the present invention is to horizontally combine the cap portion of the blower adapter and the blowing hose connecting portion horizontally to solve the above-mentioned end, and to form a cylindrical line insertion tube having a smaller diameter than the blowing hose connecting portion on the top of the blowing hose connecting portion However, by forming a stepped portion in the cap portion to form a different diameter of the cap portion to be used in two or more pipes of different diameters with one blow adapter, and can be used by inserting the auxiliary cap different in diameter from the cap portion It can also be used for pipes of other diameters.

In addition, the present invention forms a through-hole through-hole by cutting the one side of the valve seat of the semi-cylinder gradually from the left side to the right side so that the knot of the through-line thread is easily removed, and the air leakage is less. This allows the knot to pass straight through the line insertion tube without stopping the blowing operation.

Referring to the configuration of the subject innovation in detail as follows.

1 is a perspective view for showing the configuration of the present invention, the blower adapter 1 of the present invention is a cap portion (13) having different diameters of the intubation tube 13 formed by the stepped portion 12 having a rubber ring 11 ( 10), a blowing hose connecting portion 20 horizontally connected to the cap portion 10, and a through-line insertion tube 30 is formed to be inclined at the upper end of the blowing hose connecting portion 20, having a valve (32) Consists of

In addition, the cap part 10 is inserted into the coupling, and is composed of an auxiliary cap (40) formed with an extra-pipe insertion pipe (43) having a different diameter by the stepped 42 having a rubber ring (41). Rubber rings (11, 41) formed on the stepped portion of the cap portion 10 and the auxiliary cap 40 facilitates the close contact of the blower adapter (1) to the cable pipe (F) during the blowing operation, and the high pressure air leaks It is to prevent that.

The through-line insertion tube 30 is formed to be inclined at the upper end of the blower hose connecting portion 20, by reducing the formation of the vortex by hinging significantly smaller diameter than the diameter of the blower hose connecting portion 20 so as not to disturb the flow of air In addition, Bernoulli's principle is to facilitate the suction of the barrel (D).

The configuration of the through-line insertion pipe 30 and the valve 32 is shown in detail in Figures 4 and 5, unlike the conventional valve configuration of the blower adapter 100 for the blower, the high-profile valve 32 is through the through-line The holes 32c are not perforated separately in different positions, but one side of the valve seat 32b having a semi-cylindrical shape rotated by the lever 31 is cut in such a manner that the diameter gradually decreases from the left side to the right side. By forming the through line through hole 32c so that the size of the diameter of the through line through hole 32c of the valve seat 32b coupled to the lever 31 can be adjusted according to the degree of rotation of the lever 31. It is made up.

Therefore, in order to reduce the leakage of air, the line through the line in a small diameter state is passed through, and if the line of knot of the line through the line through hole (32c) is slightly rotated lever 31 to the right by the line through hole ( By increasing the diameter of 32c), only the knot is passed through, and the lever 31 is reversed to return the line through hole 32c to its original state, thereby minimizing the loss of air leakage, and thus more powerful wind pressure can be supplied into the pipeline. It would be.

In other words, in order to reduce the amount of air leaking to the outside in order to increase the efficiency of the blower adapter 1 of the present invention, the diameter of the through-through line through hole 32c is adjusted to almost the same as the diameter of the through-line line so that the knot is reduced. If the through line without passing through is made, if the line has a short line to make a knot, or if the line through the knotted line has to pass, the diameter of the line through hole 32c by the lever 31 After raising the knot to pass through the worker will be able to minimize the leakage of the air by immediately returning the through-line through hole (32c).

In addition, the present invention can be passed through the knot part of the barrel line only by the operation of the lever is easy to work the line, it has the effect that does not have to stop the blowing operation.

In addition, looking at the effect of the cap portion 10 and the auxiliary cap 40 to be able to use the present invention blower adapter (1) selectively to the diameter of the various cable conduits to avoid replacing the blower adapter as conventional In general, since the diameter of the cable line (F) is widely used in the 45mm, 50mm, 80mm, 100mm, the air inlet pipe (13) and the auxiliary cap (40) of the cap 10 so that the blower adapter can be used most commonly ), The diameter of the extra-pipe intubation 43 was limited to 45 mm, 50 mm, 8 Q mm, 100 mm. Of course, the size of the diameter may vary depending on the intention of the manufacturer or the user's order.

Accordingly, the rubber ring 11 is inserted into the pipe line by inserting the in-pipe inlet pipe 13 of the cap 10 into the pipe without using the auxiliary cap 40 as shown in FIG. 6 in a large cable pipe such as 80 mm or 100 mm. After close contact with the air blower to allow the barrel barrel (C) and the barrel to penetrate the conduit, using a secondary cap (40) as shown in Figure 7 for the cable pipeline with a small diameter, such as 45 mm or 50 mm However, the extra-pipe intubation 43 of the auxiliary cap 40 is extrapolated to the end of the conduit to be in close contact and then blow operation. Therefore, the inner circumferential surface of the extra-pipe intubation 43 of the auxiliary cap 40 is preferably inclined in a tapered shape.

In this way, the blower adapter of the present invention forms the diameter of the in-pipe intubation pipe formed in the cap part by the stepped jaw, and by forming the extra-pipe intubation pipe with different diameters by the auxiliary cap, four or more pipes having different diameters with one blower adapter. It can be used selectively, and the through-hole through-hole of the valve can be adjusted to a small diameter and a large diameter according to the degree of rotation of the lever has less air leakage has the effect of supplying a strong wind pressure into the cable pipe.

In addition, since the blowing hose connection part and the cap part are located in a straight line, there is no closed end of blowing pressure due to impact energy, and the diameter of the line insertion tube is significantly smaller than the diameter of the blowing hose connection part, thereby reducing the occurrence of vortex. In order not to obstruct the flow of air, the through-line insertion tube is formed to be inclined at the upper end of the ventilation hose connection portion by making the intake of the line more smoothly has an effect that can be quickly and easily work.
