A mechanical counting device

Abstract

The invention discloses a mechanical counting device, comprising a left C-shaped cavity, a right C-shaped cavity and a cylindrical cavity, wherein the left C-shaped cavity and the right C-shaped cavity are combined to form a diamond-shaped cavity, and the diamond-shaped cavity is arranged in the cylindrical cavity and fixed at the bottom of the cylindrical cavity; A left C-shape cavity bottom is fixedly connected with a cylindrical cavity bottom, At that bottom of the right C-shape cavity, An upper part of that filling port is provided with a sealing cover, A seal pressure cap is arranged at the opening of the cylindrical cavity, a threaded hole is arranged between the sealing pressure cap and the cylindrical cavity, the sealing pressure cap and the cylindrical cavity are connected and sealed by fixing bolts in the threaded hole, and a circular steel ball passing hole and an adjusting stopper are arranged on the middle wall of the diamond-shaped cavity formed by the combination of theleft C-shaped cavity and the right C-shaped cavity. The mechanical counting device of the invention can accurately record the number of rotation turns of the pig, judge the running track of the pig, and is favorable for evaluating the cleaning efficiency of high-pressure pipelines with pressure impact such as ore slurry and petroleum pipelines by using the pig. The utility model has the advantagesof simple structure and convenient use, and is favorable for popularization and application.

Description

technical field [0001] The invention relates to the technical field of machinery, in particular to a mechanical counting device. Background technique [0002] At present, when cleaning high-pressure pipelines with pressure shocks such as ore slurry and oil pipelines, it is necessary to measure the rotation of the pig to judge the cleaning effect. The existing technology generally uses an ink pen on the pig to mark. After the marking is completed, the pig is installed in the slurry pipeline and launched. When the pig reaches the destination, the pig is taken out. After taking it out, observe the ink mark of the pig to see if there is any rotation, and then judge the rotation of the pig in the pipeline. This method of metering rotation has the defect that it can neither accurately judge the number of rotations nor the running track of the pig, and cannot evaluate the cleaning effect of high-pressure pipelines with pressure shocks such as ore slurry and oil pipelines using pig...

AI Technical Summary

Problems solved by technology

[0004] In view of the above-mentioned defects of the prior art, the technical problem to be solved by the present invention is that the use of pigs in the prior art has pressure shocks to the high pressure of ore slurry and oil pipelines, etc. When the pipeline is cleaned, the number of rotations cannot be accurately judged, and the defect of the pig's running track cannot be judged
