Embodiment Construction
[0019] The present invention will be further described below in conjunction with the accompanying drawings.
[0020] Such as figure 1 As shown, the present invention has invented a rotary pig for unblocking, which includes four parts: a pig main body, a rolling mechanism, a transmission mechanism, and a cutting knife 23. It is characterized in that a transmission mechanism is installed in the middle of the pig main body, and a rolling mechanism Installed on the outer wall of the pipe pig cylinder 7, the cutting knife 23 is installed on the front end of the pipe pig, and is connected with the front end of the rotating shaft 22 in the transmission mechanism.
[0021] Described rolling mechanism is made up of roller 10, roller bracket 9, support seat 8, spring 16, and roller 10 is installed on the roller bracket 9, and roller bracket 9 is installed on the support base 8, has a series of threaded holes on the support base 8, through The bolt 17 is fixed on the outer wall of the p...

The invention relates to a rotary pig for blocking removal. A rotary plug-removing pig is mainly composed of a pig main body, a rolling mechanism, a transmission mechanism and a cutting knife. The rolling mechanism is installed on the outer wall of the pig cylinder and placed between the front and rear cups. The transmission mechanism is installed in the center of the main body of the pig and connected with the rolling mechanism through a belt. The two front ends of the rotating shaft in the transmission mechanism are connected. When the pig moves, it drives the roller in the rolling mechanism to roll, and the roller drives the transmission mechanism to rotate through the belt, thereby driving the cutter to rotate, so that the pig moves forward and cuts the impurities on the pipeline wall and in front of the pipeline, making the impurities Miniaturize and discharge the pipeline with the pig to achieve the purpose of cleaning the pipeline and preventing blockage. The invention can effectively relieve the jamming failure of the pipeline due to hard and abundant dirt, and can realize the function of cutting dirt while moving forward, saving resources and being economical and applicable.
Description
technical field [0001] The patent of the present invention relates to the technical field of pipeline cleaning, and is a rotary plug-removing pig. Background technique [0002] After oil and natural gas pipelines have been in operation for a period of time, it is inevitable that a lot of oil, wax, dirt, sediment, and even rust will be deposited or adhered to the inner wall of the pipeline. The dirt attached to the inner wall of the pipeline will affect the normal conveying capacity of the pipeline. In severe cases, the pipeline will be blocked, which will eventually lead to accidents. Therefore, the pipeline must be cleaned regularly. However, the traditional pig is sealed by a cup or a ball to increase the back pressure, and then rely on the pressure difference between the front and rear to push it forward for cleaning. However, this type of pig does not have the ability to automatically unblock. When the pig encounters many and hard attachments, it is easy to form a block...
