Background
In China, metal ore resources are rich in lean ores and rich ores, and are buried deeply, and a large number of goafs are formed after continuous mining. The traditional goaf detection has geophysical prospecting and drilling methods. The geophysical prospecting method has high efficiency and low cost, but the delineation in the later period is abnormal, the void ratio is low, and the precision is not high; the drilling is reliable, but the workload is large, the efficiency is low, the cost is high, and how to better develop the goaf detection is always a difficult problem. With the appearance of three-dimensional laser measurement means, a chance is brought to goaf detection. The goaf three-dimensional laser scanner is specially used for detecting an underground mine stope and a goaf, and becomes a common method for underground goaf measurement, and detection results can be directly used for calculating the volume and the roof area of the goaf, establishing a goaf three-dimensional model and calculating the residual ore storage capacity, so that the goaf three-dimensional laser scanner can be further used for guiding related mining management and control processes such as goaf filling, ore pillar blasting design, stoping lean loss control, goaf stability analysis and the like.
When personnel do not enter a goaf or a potential dangerous area to carry out measurement, a laser scanner is usually erected on a telescopic, firm and light metal connecting rod and then extends into the goaf to carry out detection. Therefore, an extension rod which is light in material, easy to carry, simple to erect, firm, reliable and easy to disassemble is needed to ensure the normal use of the goaf three-dimensional laser scanner.
The underground goaf deformation measurement and safety monitoring application of the three-dimensional laser scanner is a specific industrial application of a three-dimensional laser scanning technology, the development of the underground goaf deformation measurement and safety monitoring application is closely combined with the characteristics of the mine industry, and the development trend of the underground goaf deformation measurement and safety monitoring technology in mine safety monitoring application is miniaturization, portability, long distance, high precision, firmness, reliability and the like. The three-dimensional laser scanning measurement technology provides accurate and reliable visual data for application occasions such as acquisition of mine goaf information, and the like, represents important goaf parameters such as goaf volume, actual goaf boundary, dilution loss and the like by specific indexes, can accurately calculate the goaf rock wall collapse amount and the like, changes the situation of estimation by subjective experience in the past, and is a new technology and an important means for safety monitoring of underground goafs. With the rapid development of mine informatization, the three-dimensional laser scanner is used as a carrier of a three-dimensional laser scanning technology and can play an increasingly important role in underground safety monitoring of mines.
The three-dimensional laser scanner does not need to enter the goaf when detecting the goaf, and can automatically scan and accurately measure the underground goaf. The technician can accurately master the actual boundary of the goaf, has important engineering significance for implementing goaf management, ore body mining around the goaf and design and construction of roadway engineering, is also beneficial to optimizing the stoping blasting design of ore pillars, further improves the economic benefit of mines and is beneficial to establishing a goaf information database.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a collecting space area three-dimensional laser scanner's extension device for laying of extension rod more can adapt to the topography condition, does not receive the limited restriction of operating space, has shortened operating time, has both reached the purpose of accurate detection in mine, ensures the safety in production again.
In order to solve the technical problem, the utility model adopts the following technical scheme:
an extension device of a three-dimensional laser scanner in a goaf comprises an equipment connecting rod, wherein the equipment connecting rod comprises a plurality of connecting rod units which are connected in an inserting manner, one end of each connecting rod unit is an inserting end, the other end of each connecting rod unit is an adaptive socket, and connecting holes are correspondingly formed in the inserting end and the socket; after being spliced and matched, the adjacent connecting rod units are fixed by a bolt with an automatic buckle sequentially penetrating through the connecting holes.
Further, the bolt is also connected with an anti-lost rope.
Furthermore, the inserting end of the connecting rod unit which is positioned at the topmost end and used for being connected with the equipment is a threaded section and is in threaded connection with the equipment.
Furthermore, the insertion end is wrapped with an elastic buffer layer.
Further, the elastic buffer layer is a wear-resistant rubber layer.
Compared with the prior art, the utility model discloses a beneficial technological effect:
extension rod and three-dimensional laser scanner connector application environment are mainly underground mine, because on-the-spot dust and moisture are heavier, scanner screw thread part often need have the lubricating oil lubrication during the connection, and through threaded connection, the connection time is longer. The utility model provides a special extension rod that is fit for three-dimensional laser scanner collecting space area operation will greatly improve the time of installation operation to reduce the rotation each other between each pole, guarantee the steady of scanning operation, and then improve the accuracy of data.
