Power transmission device and method for pipeline washing

Abstract

The invention belongs to the technical field of pipeline washing, and particularly relates to a power transmission device and method for pipeline washing. The power transmission device comprises a power mechanism and a transmission mechanism. Through the transmission mechanism, the power mechanism drives a washing mechanism to achieve washing operation. The power mechanism comprises a power shaft motor and a spiral spring motor, and a power shaft and a spiral spring achieve coaxial power output through a shaft-spring differential device. The transmission mechanism is formed in a manner that a variable speed motor drives a rolling wheel mechanism, and the rolling wheel mechanism is formed in a manner that a rolling wheel support is provided with a rolling wheel. The power shaft and the spiral spring which are coaxial are wound on the rolling wheel, and the tail end of the power shaft and the tail end of the spiral spring are transmitted to a pipeline to be cleaned through a supporting bracket to carry out washing operation. According to the power transmission device for pipeline washing, a belt wheel and a conveyor belt are utilized for enabling two powers of the power shaft and the spiral spring to be output coaxially, the spiral spring and the power shaft coaxially transmit power, the spiral spring which is located outside has the functions of extending, retracting, propelling, guiding, abrasion reducing and twisting preventing, stable power is provided for rotary cutting equipment, and the power can be adjusted at will.

Description

technical field [0001] The invention belongs to the technical field of pipeline cleaning, and in particular relates to a power transmission device and method for pipeline cleaning, which can be used to clean boiler coils and pipelines in the fields of petroleum, chemical industry, industrial mining and the like. Background technique [0002] Taking oil pipelines as an example, boiler coils and pipelines are very important links in the smelting and transportation of oil. Due to the large amount of impurities in crude oil, dirt (BaSO4) is easily generated on the inner wall of the pipeline, which can be as slow as half a year and as fast as three years. Monthly, the dirt in the pipe wall will occupy more than 70% of the space in the pipe, and the ground will affect oil output and reduce production. [0003] The usual solutions are as follows: 1. Chemical corrosion method; 2. Vibration method; 3. High-pressure sand blasting method; 4. Remove the clogged coil or pipe, transport i...

AI Technical Summary

Problems solved by technology

[0004] For the above methods, 1. Chemical corrosion method. Due to the particularity of dirt components (main components of dirt: calcium carbonate, barium sulfate), this method is difficult to remove completely, and the corrosion of dirt will also corrode the pipe wall; 2. 1. Vibration method, this method can hardly complete the removal of dirt at the corner, and the shedding lumps cannot be discharged; 3. High-pressure sandblasting method, this method has no obvious effect, the corner and the middle section are not cleaned thoroughly, and the cleaning time cannot be grasped. It is easy to cause the possibility of pipeline wall wear; 4. The method of returning to the factory for reprocessing, this method is expensive and the cycle is long

[0005] Based on the disadvantages of the above methods, there is an urgent need for a descaling equipment that can overcome the above disadvantages. For the cleaning of coiled pipes, in order to achieve one-time complete cleaning, a necessary condition is that the cleaning equipment must have certain It is flexible and can bend with the bending of the pipeline. To achieve the function of bending and rotating for cleaning equipment, one of the most difficult problems that needs to be solved is how to provide continuous power to the cleaning equipment during the rotation process. At present, there are direct power to the cleaning equipment Increase the power motor to let the motor rotate with the cleaning equipment. Generally, this type of motor has relatively small power and poor work efficiency, so it is not suitable for cleaning large-scale mechanical pipelines.
