Description

Guide structure of pipeline cleaning device

technical field

The invention relates to a pipeline cleaning device, in particular to a guiding structure of the pipeline cleaning device.

Background technique

In the industrial field, it is necessary to use pipelines to transport media, and high-pressure water guns or chemical detergents are often used to clean hard dirt or grease on the inner walls of pipelines, but the above methods have limitations. If there are many openings in the pipeline, the descaling effect is often difficult to control when cleaning with a high-pressure water gun, thus failing to achieve the desired purpose. If the pipeline material has poor corrosion resistance, it is not convenient to use chemical detergents, and improper use will pollute the environment. Therefore, there is a need for a pipeline cleaning device that is easy to use, has no pollution to the environment, and has an excellent cleaning effect.

For example, the utility model patent CN203140382U discloses a pipeline descaling and cleaning device, which is characterized in that: the cleaning device includes a cylindrical motor, and the working end of the motor front is provided with a descaling head and a propeller blade. There are rollers in contact with the inner wall of the pipeline at both the front and the rear, and an elastic bracket is arranged between the rollers and the motor. The number of rollers is at least three, and they are evenly distributed on the circumference. There are openings on the pipeline to match the openings. There is a pay-off box, and a pay-off shaft is rotatably supported in the pay-off box, and the wires of the motor are wound on the pay-off shaft. Although it adopts a purely mechanical way to clean the pipeline, it still has the following defects: the descaling head only uses a wire brush or a conical grinding wheel, which has poor descaling effect, and once it encounters solid dirt, it cannot be removed. It can also lead to a blockage of the cleaning device. The structure of the elastic bracket arranged between the roller and the motor is too simple to adapt to the unevenness of the inner wall of the pipeline, and it is easy to be blocked and stop working. Moreover, the pulley structure cannot perfectly coincide with the inner wall of the pipeline, and the guiding effect is poor. Only a single wire is connected to the end of the whole body, and the wire is easily broken, causing an accident. An additional tracking device is required to determine the operating position of the cleaning device, which not only increases the cost of use but is also inconvenient to use, and the cleaning device will be lost if there is a slight negligence. When the body of the cleaning device has a large resistance and needs to be retracted, it is almost impossible to rely on the rear thrust generated by the propeller, which causes great inconvenience to the use process.

Contents of the invention

The purpose of the present invention is to provide a guiding structure for a pipeline cleaning device, which solves the problem that the pulley structure in the above patent cannot fit well with the inner wall of the pipeline and the guiding effect is poor.

The object of the present invention is achieved in the following way: a guiding structure of a pipeline cleaning device, which is installed on the side of the pipeline cleaning device body, the guiding structure includes a foot, a regular pentagonal bracket, and five bracket sleeves are evenly distributed on the same plane in the circumferential direction of the bracket There are several grooves at the contact end of the tube, the support leg and the tube wall, and a leg spring column for inserting the corresponding support sleeve is provided on the opposite side, and an elastic structure is provided between the support sleeve and the support spring column.

The pipeline cleaning device also includes a body, a shaft driven by the body, a descaling head arranged at the front end of the shaft, a turbine arranged on the shaft, electric wires connected to the body, and a discharge box arranged on the pipeline, The technical points are: the descaling head is a cone grinding wheel or a scraper; the wire shaft and the steel wire shaft with a hollow structure inside the shaft are arranged in the wire release box. On the box; the two ends of the wire shaft run through both sides of the pay-off box, and the outer wall of the middle part of the wire shaft is provided with a wire hole that communicates with the hollow structure of the wire shaft. One end of the wire shaft is provided with a coiled measuring line, and the other end of the wire shaft is provided with an insulating ring. , there is a carbon brush on the insulating ring, and the wire coiled on the wire shaft passes through the wire hole and connects with the carbon brush through the hollow structure; one end of the steel wire shaft runs through the pay-off box, and the end is provided with a control hole, and the steel wire shaft is coiled There are steel wires, and the steel wires are connected to the ends of the body.

The discharge box is sealed and installed on the opening of the pipe wall through the rubber ring.

The discharge box is welded on the opening of the pipe wall.

The scraper includes a regular pentagonal bracket and five T-shaped blades, the vertical sides of the T-shaped blades are inserted into the corresponding bracket sleeves, and an elastic structure is arranged between the T-shaped blades and the bracket sleeves.

The transverse edge of the T-shaped blade is arc-shaped.

In view of the problems existing in the traditional descaling methods of high-pressure water guns and chemical reagents, the crankshaft is used to drive the turbine to rotate to generate driving force to drive the body to move in the pipeline. During the movement, the cone grinding wheel or scraper at the end of the crankshaft will The hard dirt or grease on the wall is removed to achieve the purpose of cleaning the pipeline. The cleaning process uses the measuring line inside the wire shaft for positioning, so there is no need to equip a tracker outside the pipeline, which saves the cost of use and makes the cleaning process simpler. The scraper blade is installed on the pentagonal bracket, which can elastically expand and contract according to the situation in the pipeline during the rotation process, avoiding the blockage of the cleaning process and improving the cleaning efficiency. A steel wire shaft is installed in the pay-off box, and there is a steel wire connected to the end of the machine body on the steel wire shaft. Once the cleaning device is blocked, it can be pulled through the dual functions of the steel wire and the turbine, and at the same time avoids the original single wire. Fracture problem.

The beneficial effects of the present invention are: the side wall of the machine body is equipped with a grooved leg, the leg is fixed on the inner wall of the pipeline through the spring elastic fiber in the bracket, and the groove structure avoids the original pulley Unstable operation of the structure, unstable support, easy to block and other problems, at the same time, it has the effect of secondary wall scraping and cleaning, improving the cleaning efficiency. In summary, the present invention has the advantages of simple manufacture, low cost, broad market prospect and the like.
