Description

Technical Field

[0001] This utility model relates to the field of suspension connection technology, and more specifically, to a suspension connection device for a mining surveying prism. Background Technology

[0002] The prism suspension connection device plays a crucial role in mine surveying. The suspension device fixes the prism to the preset measurement point through a mechanical structure, preventing the prism from shifting due to vibration, wind, or human touch. This ensures that the reflected signals received by equipment such as total stations are stable and reliable. For example, in underground roadway deformation monitoring, millimeter-level deviations in the prism position can directly affect the accuracy of roof settlement data.

[0003] During the suspension connection process of a mining surveying prism, the prism head needs to be installed in the designated position. However, due to the lack of guiding and locking during the compression of the installation part, the suspension connection is prone to misalignment, resulting in poor stability.
