Measuring instrument of static friction coefficient of communication pipeline

Abstract

The invention relates to a measuring instrument of static friction coefficient of a communication pipeline. A testing rack is provided with a platform; a clamping device and a measuring head push-pull device are arranged on the platform oppositely; a static friction transmission device is connected with the measuring head push-pull device; and when a spring in the static friction transmission device is displaced to a certain position, and the measuring head push-pull device starts to move, a push-pull force gauge on the measuring head push-pull device measures the static friction of a tested piece, and further calculates the static friction coefficient of the tested piece. The invention also discloses a method for carrying out static friction coefficient test and carrying out magnitude tracing on the existing measuring instrument by adopting the static friction coefficient of the communication pipeline. In the invention, the integration level is high, the measurement is accurate, and the defect that the existing measuring instrument adopts the process of observing and measuring by naked eyes to judge a measured result subjectively. By utilizing the measuring instrument disclosed by the invention, the existing measuring instrument also can be calibrated, so that the accuracy of magnitude tracing of the existing measuring instrument is improved and further the quality of communication pipeline engineering is guaranteed.

Description

technical field [0001] The invention belongs to the field of measurement, in particular to a measuring device for the static friction coefficient of a communication pipeline. Background technique [0002] High-density polyethylene silicon core plastic pipe (referred to as silicon core pipe) is composed of high-density polyethylene (HDPE) outer wall, outer color strip and solid silicon inner lubricating layer. It is laid directly underground and passes through communication optical cables. The silicon core tube that runs through the entire road connects a series of outfield equipment such as vehicle detectors, cameras, emergency phones, and information boards with monitoring centers, communication centers, and toll stations through man (hand) holes, so that they can be connected through optical cables. Signal and data transmission enable road operators to grasp road information in a timely manner, deal with emergencies, provide timely rescue, and guide traffic, so as to ensur...

Problems solved by technology

[0008] However, the above-mentioned measuring instrument has the disadvantage that the time point at which the standard test rod in the sample holder starts to slide down in the communication pipe needs to be determined by the operator with the naked eye, and its accuracy will depend on the operator's determination of the time point. The proficiency in the use of the instrument and its operating experience, so the use of this measuring instrument will have a certain measurement error
