Digital measuring device and method for shaft section area

Abstract

The invention relates to a digital measuring device and method for a shaft section area. The device comprises a box type electric winch, an intelligent counter weight and a handheld intelligent terminal. The method includes the steps of firstly, fixing the box type electric winch onto a measuring fixing platform with a precise measuring point, determining a checking setting point, and mounting the intelligent counter weight; secondly, using the handheld intelligent terminal to input elevation, measuring frequency, data record file name instructions to remotely control the box type electric winch and / or the intelligent counter weight to reach an appointed position so as to perform measuring, recording and real-time measuring data feedback; thirdly, by a user, determining a next measuring position according to the feedback measuring data; fourthly, repeating the second step and the third step until the measuring is completed.

Description

technical field [0001] The invention belongs to the technical field of mining surveying and mapping, and in particular relates to a digital measuring device and method for shaft sections. Background technique [0002] At present, the surveying and mapping devices for shafts mainly include vertical steel wire measuring devices for shafts and laser pointers, but they all have some shortcomings. [0003] The main structure and working principle of the shaft plumb steel wire measuring device are: hand-cranked winch, lowering of the steel wire, manual hanging of a heavy hammer, manual measurement, and manual recording. It has the following disadvantages: 1. The labor intensity is high; 2. Professionals are required to operate, and it is difficult to check the clamping board; 3. The steel wire is easily broken due to corrosion and endangers safe operation; 4. The heavy hammer needs to be lowered to the bottom of the well following the bucket and manually lifted It requires manual...

It has the following disadvantages: 1. The labor intensity is high; 2. Professionals are required to operate, and it is difficult to check the clamping board; 3. The steel wire is easily broken due to corrosion and endangers safe operation; It requires manual measurement and manual recording, data is easily lost, and retesting is extremely difficult; 5. The database cannot be accumulated and processed well, and the excavation and installation cannot be guided at the same time; 6. The deformation of the shaft structure cannot be dynamically monitored during the construction period

It has the following disadvantages: 1. The fixed structure of the pointing instrument is prone to deflection due to blasting shock and vibration, difficult to correct, frequent, and labor-intensive; 2. It requires professional operation, manual measurement and manual recording, and data is easily lost. Retesting is extremely difficult; 3. The database cannot be accumulated and processed well, and the excavation and installation cannot be guided at the same time; 4. The deformation of the shaft structure cannot be dynamically monitored during the construction period; 5. The laser is affected by the high air humidity, dust, and airflow in the well Divergence, poor long-distance measurement accuracy, strong randomness in measurement control, poor quality control and verification of engineering specifications, and easy to cause quality defects or even unqualified products; 6. It takes a long process time and high cost
