Abstract

The invention discloses a coaxial protection device for field measurement and a spanner thereof. The protection device comprises a protection cover arranged on a concrete observing pillar, wherein a coaxial bracket is arranged inside the protection cover; the protection cover and the center line of the coaxial bracket are overlapped; the coaxial bracket has a multilayer structure; a prism shaft is mounted on the center line of each layer of the coaxial bracket; a lower screw of the prism shaft is screwed into a bolt hole; an adjustment disc is correspondingly arranged above the prism shaft on the top of the coaxial bracket; a prism is mounted on each prism shaft; multiple pairs of fixing screws are arranged on the periphery of the bottom of the protection cover; each pair of the fixing screws are symmetrically distributed. The spanner is in a T shape; an opening is formed in the lower end of the spanner and the lower end is in an inverted U-shaped groove; the inverted U-shaped groove and the screw heads of the fixing screws are completely matched. By adopting the device, the prisms used when a total station performs automatic observation are coaxial, and the prisms can be effectively protected; the observation precision and the labor efficiency can be improved, the damage and the loss of the prisms are reduced, and the normal work of the total station is guaranteed.

Description

technical field [0001] The invention relates to the field of field measurement devices, in particular to a field measurement coaxial protection device and a wrench thereof. Background technique [0002] The deformation of buildings and landslides involves major public safety. Automatic total station, also known as measuring robot, is the main instrument for automatic deformation measurement at present. Its technical composition includes coordinate system, manipulator, transducer, computer and controller, closed-loop control sensor, decision making, target acquisition and integrated sensor, etc. It is a set of automatic target recognition, automatic aiming, automatic measuring A measurement platform integrating angle and distance measurement, automatic target tracking and automatic recording. [0003] The prism used by the automatic total station for observation is an important part of the total station, which is expensive. Once it is damaged or lost, the automatic total sta...
