Abstract

The invention discloses a propulsion mechanism and belongs to the technical field of pipeline pigging. The propulsion mechanism includes a fixed bracket, a push rod, a push head and a rotary mechanism; the push rod is connected to the fixed bracket, and the length of the push rod can be adjusted, and the first end of the push rod is movably connected with one end of the rotary mechanism, and the rotary mechanism can Drive the center line of the push head to rotate around the center line of the push rod, the first end of the push head is fixedly connected with the other end of the rotating mechanism, and the second end of the push head is provided with a cavity. Because the length of the push rod can be adjusted in the present invention, it can ensure that the push rod pushes the tracking transmitter to the big and small ends of the spherical cylinder. In addition, the rotating mechanism can drive the center line of the push head to rotate around the center line of the push rod, so that the push head can be adjusted without adjusting the fixed bracket to ensure that the center line of the push head coincides with the center line of the ball cylinder, so that It is ensured that the cavity can be covered on the tracking transmitter, and it is avoided to set up supporting propulsion mechanisms separately for pipes of different sizes.

Description

Promotion agency technical field [0001] The present invention relates to the technical field of pipeline pigging, in particular to a propulsion mechanism. Background technique [0002] After the pipeline transports the medium for a long time, phenomena such as condensed oil, wax deposition and scaling easily occur on the inner wall of the pipeline, Therefore, the effective flow area of ​​pipeline transportation is reduced, and the frictional resistance of pipeline transportation is increased. In addition, when condensation occurs on the inner wall of the pipe, When oil, wax deposition, scaling and other phenomena are serious, it is likely to cause blockage of the pipeline, which can easily lead to the occurrence of safety accidents. because Therefore, in order to reduce the friction of pipeline transportation and improve the safety of pipeline transportation, the pipeline can be pigged regularly. To remove condensed oil, wax deposits, scaling, etc. on the inner wall ...
