Description

Technical Field

[0001] The utility model relates to the technical field of scanners, and specifically relates to a fixing device for a three-dimensional modeling scanner used in prospecting measurement. Background Art

[0002] Three-dimensional laser scanners for mined-out areas are specifically used to detect underground mine stopes and mined-out areas, and have become a common method for measuring underground mined-out areas. The detection results can be directly used to calculate the volume and roof area of the mined-out area, establish a three-dimensional model of the mined-out area, and calculate the residual ore reserves, so as to be further used to guide related mining management and control processes such as mined-out area filling, pillar blasting design, stope loss and dilution control, and mined-out area stability analysis.

[0003] When carrying out measurement work without personnel entering the mined-out area or potentially dangerous areas, the laser scanner is usually mounted on a telescopic, sturdy and lightweight metal connecting rod and then extended into the mined-out area for detection. Therefore, in order to prevent the three-dimensional laser scanner from shaking or falling and affecting the measurement work, a fixed support must be used to fix the metal connecting rod. Due to the small cross-sectional size of the underground roadway engineering and the unevenness of the roadway wall surface, there are disadvantages such as heavy fixed support materials, difficult handling, large erection difficulty, instability, and difficult disassembly. Therefore, there is an urgent need for a fixing device for a three-dimensional modeling scanner used in prospecting measurement that can be disassembled easily for handling and can ensure the normal use of the three-dimensional laser scanner for mined-out areas.

A support member is sleeved on the support rod 3. A pushing assembly for pushing the support member to move outward is installed on the positioning cylinder 1. An extension rod 4 is inserted into the positioning cylinder 1, and a scanner is installed at the end of the extension rod 4.

[0017] The pushing assembly includes two limiting rings 5 and a fixing ring 6. The two limiting rings 5 are respectively sleeved on the support rod 3. The fixing ring 6 is sleeved on the positioning cylinder 1. A connecting rod 7 is hinged between the fixing ring 6 and the limiting ring 5. A threaded ring 8 is rotatably installed on the fixing ring 6, and the threaded ring 8 is screwed onto the positioning cylinder 1.

[0018] Symmetric limiting strips 9 extend outward on the outer side wall of the extension rod 4, and the limiting strips 9 are inserted into limiting grooves 10 opened on the inner side wall of the positioning cylinder 1.

[0019] The support member includes a sleeve 11. The sleeve 11 is sleeved on the support rod 3. A support seat 12 is installed at the end of the sleeve 11.
