Measuring mechanism capable of automatically cleaning tape mud dirt

Abstract

The invention discloses a measuring mechanism capable of automatically cleaning tape mud dirt. The measuring mechanism is used for measuring the depth of the foundation pit on a foundation, and includes a measuring support rod, one end of the measuring support rod is in contact with the foundation, and the other end of the measuring support rod is used for being held by an operator, a pulley is arranged in the middle of the measuring support rod, a rolling ruler is arranged at one side, away from the foundation, of the end part of the measuring support rod, a ruler belt is arranged in the measuring tape, the ruler belt falls into the foundation pit after being supported and guided by the pulley, a plumb bob is arranged at the end of the ruler belt, a dirt removing sleeve is arranged outside the measuring tape in a sleeved mode, the dirt removing sleeve comprises a sleeve body which is attached to the ruler belt shell, the two ends of the sleeve body are provided with an upper dirt removing piece and a lower dirt removing piece, the upper dirt removing piece and the lower dirt removing piece are respectively attached to the upper bottom surface and the lower bottom surface of the ruler belt, long-distance measurement can be carried out by an operator standing on the safety position, and the measurement center can be accurately found, so that the measurement is accurate; and thetelescopic rod can be arranged to adapt to different ranging situations and operators with different heights.

Description

technical field [0001] The invention relates to the field of construction engineering, in particular to a measuring mechanism capable of automatically cleaning mud and dirt from a measuring tape. Background technique [0002] After the construction of the pile foundation is completed, it is necessary to measure the excavation depth of the pile foundation. At present, when the engineering project personnel measure the depth of the pile hole, they place a wooden board with a certain width and thickness in the middle of the top of the pile hole, and the surveyor stands on it to measure , is very dangerous. Contents of the invention [0003] The purpose of the present invention is to overcome the above-mentioned problems in the prior art, and propose a measuring mechanism that can automatically clean up the mud and dirt on the tape, which can use the operator to stand in a safe position for long-distance measurement, and can accurately locate the measurement Center to ensure ...
