Description

Technical Field

[0001] The utility model belongs to the technical field of construction measurement support equipment for structural surfaces such as rock masses and cave walls, and in particular relates to a support device for a rod-type horizontal displacement measuring rod. Background Art

[0002] The support frame of the rod-type horizontal displacement meter measuring rod is fixed on the structural surface such as wall, rock mass, cave wall, etc. It is usually made of steel bars or angle irons welded into a triangular support frame installed on the structural surface to provide support for the measuring rod and transmit monitoring data.

[0003] This type of support frame is fixed to the structural surface, and it is not firmly fixed by screws in only one direction. Because of its small force-contact area, it is easy to shake. In addition, the measuring rod is placed on the support frame and directly fixed to the support frame, so that the connection between the measuring rod and the support frame is not tight. The use of this method to install the rod-type horizontal displacement meter measuring rod not only has low quality and monitoring accuracy, but also the exposed end of the support frame poses a safety hazard, which may cause the monitoring personnel to have their skin scratched or their clothes damaged during operation.
