Description

[0002] Non-powered hybrid pneumatic pipeline cleaning ICT moving trucks [

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a vehicle for cleaning a pneumatic hybrid pneumatic ICT pipe, and more particularly, to a motor vehicle used as a power source for a wheel and a rotating part of a main body, It is possible to prevent safety accidents in advance and to enhance the safety of the apparatus and to prevent the nozzle formed at the tip of the jetting part from colliding with the inner wall surface of the jetting tube through the collision preventing means formed at the end of the jetting section, The present invention relates to a non-power-supply hybrid pneumatic ICT duct cleaning truck which can enhance the structural safety of the apparatus.

Generally, water pipes, dirt, gas and the like are supplied to the inner wall of the pipe when the pipe is aged and used for a long period after installation, such as water pipe of middle or large diameter for supplying tap water, small diameter water pipe, sewage pipe for discharging sewage, Various kinds of foreign substances contained in the fluid of the fluid are sludged and when the conduit is made of a metallic material, the inner surface of the conduit is oxidized to generate rust, and these are solidified to form a scale layer.

Since the sludge or scale layer formed by the deposition of rust and foreign matter formed on the inner surface of the fluid channel is gradually thickened and solidified with the lapse of time, it obstructs the smooth flow of the fluid, And the scale layer attached to the pipeline melts into the fluid, causing the fluid to be contaminated.

Particularly, there has been reported a case where the operation of the reactor due to the inflow of foreign matter is stopped in the nuclear water seawater piping.

Therefore, in order to solve such a problem, there is a scrapers method in which a pipe is washed, a separate device is pulled into the pipe to dredge sediments accumulated in the pipe, Water jet method, and a poly-pig construction method in which the scale layer on the inner surface of the pipe is removed by rushing the poly pigs by high pressure have been developed and applied in the field.

Here, a structure of a conventional moving track for cleaning ducts, which removes sludge and scale layers in a duct by using high-pressure water, includes a main body having a plurality of wheels mounted thereon for movement, A rotary part connected to the washing water storage tank of the washing tub for spraying high pressure water to the inner wall surface of the duct P and a high pressure water sprayed through the spray part by rotating the spray part, And a control unit for controlling the operation of the apparatus.

That is, since the main body gradually progresses in one direction inside the pipeline, the high pressure water sprayed from the spray portion is uniformly sprayed to the pipeline wall, so that the sludge and the scale layer formed on the pipeline wall are removed by water pressure.

However, the conventional moving vehicle for pipeline cleaning has the following problems.

First, there is a safety problem in that a driving motor serving as a power source of a wheel and a rotating part of the main body operates electricity as a power source, thereby increasing the risk of electric safety accidents.

In particular, there is a problem that the risk of electrical safety accidents is high due to the characteristic of removing the sludge and scale layer on the surface of the pipe by using high-pressure water.

Secondly, the nozzles at the end of the jetting part collide with the wall surface of the jetting part frequently due to the swaying caused by the movement of the inside of the rugged pipe due to the sludge or scale layer, so that the nozzle part is damaged or broken, There is a problem that the use of the apparatus is somewhat uncomfortable.

Third, when the pipe wall is cleaned using the high-pressure water, the pipe wall coating is performed. In general, before performing the painting work, the cleaning state of the pipe surface, that is, the roughness of the pipe surface And the like.

However, when the cleaning is completed, it is impossible to accurately check the surface roughness of the pipeline due to the foreign matter (sludge or scale layer) and water deposited on the wall surface of the pipeline or the bottom of the pipeline so as to collect and remove foreign substances in the pipeline. Wait for the water to dry.

Therefore, it takes too much time to check the illuminance of the channel surface.

Further, since the sludge or scale layer is not completely removed from the portion where the roughness of the surface is measured in the process of checking the roughness of the pipeline surface, the coating performed in this state can be easily peeled off, Cleaning is required, so that the operation is very troublesome and inconvenient.

Disclosure of Invention Technical Problem [8] The present invention has been proposed in order to solve all of the above problems, and an object of the present invention is to provide a driving motor which is used as a power source for wheels and rotating parts of a main body, Not only can safety of the apparatus be prevented, but also the nozzle formed at the end of the jetting portion collides with the inner wall surface of the jetting passage through the collision preventing means formed at the jetting end portion and is frequently damaged or damaged Which can enhance the structural safety of the device, by providing a non-powered hybrid pneumatic ICT duct cleaning vehicle.

In addition, the foreign matter (sludge or scale layer) on the inner wall surface of the pipe is removed by the high-pressure water sprayed through the jetting portion, and the inner wall surface of the pipe in which the foreign substance is removed is directly roughened (roughness) It is possible to perform the process very quickly because no additional inspection time is required to check the illuminance of the inner surface of the pipe as in the prior art. In addition, if there is a portion where the illuminance is high in the process of checking the illuminance, The present invention provides a cleaning vehicle for cleaning a pipeline that can be cleaned efficiently and conveniently because the foreign matter on the surface of the pipeline can be removed through the spraying part.

In order to accomplish the above object, according to the present invention, there is provided a non-powered hybrid pneumatic ICT pipe cleaning truck, comprising: a main body having a plurality of wheels installed thereon for movement; a main body installed in front of the main body, A rotary part for rotating the spray part to spray uniformly the high pressure water sprayed through the spray part on the surface of the pipe P and a control part for controlling the operation of the device In the duct cleaning tank,

When the tip of the jetting part approaches the wall surface of the duct, the rotating ball of the jetting prevention part collides with the channel wall surface before the nozzle of the jetting part to prevent the nozzle of the jetting part from colliding against the wall surface, So that the collision restraint is relieved by the impact due to the collision and descends on the guide groove of the guide pipe to naturally absorb the shock, And prevent damage and breakage of the collision preventing means due to collision with the wall surface of the duct.

The at least one roughness measuring sensor may be formed at an end of the stationary frame and rotated together with the stationary frame to measure surface roughness of the channel wall. A protection cover formed at an end of the fixing frame and spraying high pressure air to the pipe wall to push water and foreign substances on the bottom of the pipe and the water on the pipe wall surface, And an air jetting means for guiding the roughness measurement of the surface of the duct wall smoothly by the roughness measuring sensor,

The air jetting means includes an air jet nozzle formed at an end of the fixed frame and jetting high pressure air to the duct wall, a compressor for generating and supplying air at a high pressure, A first supply hose connected at one end to the compressor and at the other end to the connection pipe to supply the air generated in the compressor to the connection pipe, and one end connected to the air injection nozzle And a second supply hose rotatably connected to the connection pipe for guiding the air supplied through the connection pipe to the air injection nozzle.

Further, it is preferable that the apparatus further comprises a transfer means for transferring the air injection nozzle of the air injection means so as to be close to the duct wall body,

The conveying means is formed on the conveying guide and is conveyed forward and backward on the conveying guide. The conveying means is coupled to the air ejecting nozzle, And a transfer cylinder coupled to the stationary frame for forcibly transferring the transfer block forward and backward,

If the distance between the air spray nozzle and the surface of the duct wall is too large, it is difficult to smoothly push out the water adhering to the surface of the wall of the air duct pipe sprayed from the air jet nozzle and the bottom of the duct, So that the nozzle is positioned close to the wall surface of the channel.

The apparatus may further include at least one distance sensor formed at an end of the stationary frame and rotated together with the stationary frame to measure a distance from the surface of the channel wall.

As described above, according to the present invention, since the driving motor used as the power of the wheel and the rotating part of the main body operates air or water as the power source, the electric power generated in the conventional moving vehicle It is possible to prevent safety accidents in advance and to enhance the safety of the apparatus and to prevent the nozzle formed at the tip of the jetting part from colliding with the inner wall surface of the jetting tube through the collision preventing means formed at the end of the jetting section, So that the structural safety of the device can be enhanced.

In addition, the foreign matter (sludge or scale layer) on the inner wall surface of the pipe is removed by the high-pressure water sprayed through the jetting portion, and the inner wall surface of the pipe in which the foreign substance is removed is directly roughened (roughness) It is possible to perform the process very quickly because no additional inspection time is required to check the illuminance of the inner surface of the pipe as in the prior art. In addition, if there is a portion where the illuminance is high in the process of checking the illuminance, The foreign matter on the surface of the pipe can be removed again through the injection part, so that the cleaning work of the pipe can be performed very efficiently and conveniently.
