AI Technical Summary

Benefits of technology

This technology allows for accurate measurement of changes over time caused by tensioning or slackening on cables attached to an apparatus called a device. By measuring this difference from another cable connected at different points along its path it becomes possible to monitor movements within specific areas without physically touching them.

Problems solved by technology

The technical problem addressed in this patented text relates to improving the efficiency and reliance for detecting slopes during various stages of civil infrastructure projects like road building works due to environmental factors including weather condition changes, land use patterns, and natural resources exploitation. Current solutions are time-consuming, expensive, require specialized tools, have limitations in their performance over different terrains, and may cause interference from other sources.

Embodiment Construction

[0027] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0028] The invention provides a large-range distance measuring instrument for slopes, which includes a guide rod 2 , a guide housing 1 and a guide base 3 . The guide rod 2 is a solid stainless steel body of equal diameter, with a diameter of 30-70mm and a length of 300-1500mm; the surface is engraved with a spiral guide groove 5, and its length is 200-1000mm. Guide housing 1 is that diameter is 42-95mm, and steel plate thickness is the stainless steel cylinder body of 2-5mm. A square slot 17 with a width of 10-15 mm is provided in the guide housing 1 for the pulling rope 6 to protrude. A metal hook 15 is installed in the center of the shell of the guide shell 1 to be connected with the pulling rope 6 of the adjacent range finder. The guide rod 2 extends outward by 30-70mm after passing through the inner diameters of the first bearings 7 of the same speci

Abstract

The invention provides a side slope wide-range distance measuring instrument and a side slope deformation real-time monitoring method. The side slope wide-range distance measuring instrument comprisesa guide rod, a guide shell arranged at the outer side of the guide rod and a guide base arranged below the guide shell; the outer wall of the guide rod is connected with the inner wall of the guide shell through a bearing; a first angle measuring device for measuring the rotary angle of the guide rod is arranged in the guide shell; a traction rope winds the outer wall of the guide rod, one end ofthe traction rope is fixed to the guide rod, and the other end of the traction rope penetrates through the guide shell; the guide base is connected with the guide shell through the bearing; the distance measuring instrument further comprises a second angle measuring device for measuring the rotary angle of the guide shell. A calculation method for distance change between every two adjacent distance measuring instruments and position coordinates of the distance measuring instruments after side slope deformation is put forward. By means of the side slope wide-range distance measuring instrument, rock and earth mass can be monitored in real time, and sliding influence area range and stratum moving conditions are determined.
