Description

Technical Field

[0001] The utility model relates to the technical field of bracket switching, in particular to a measuring prism bracket switching adapter device. Background Art

[0002] For existing railways that have been in operation for many years, their stability and smoothness are related to whether the train can run normally at the designed speed, and have a great impact on the safety and comfort of train driving. This requires the provision of accurate measurement and control benchmarks to achieve this. The measurement and control benchmarks are composed of high-level control points and track control network points. The measurement and setting of high-level control points is carried out by a high-precision GNSS (Global Navigation Satellite System) receiver to statically observe GNSS satellite signals, and synchronously measure offline control benchmarks, and obtain high-level control benchmarks through matching software; the measurement and setting of track control network points is carried out by a high-precision intelligent total station to observe prisms through free station setting, and at the same time observe prisms on high-level control points, obtain the corner relationship between each track control network point and the high-level control point benchmark, and obtain the track control network control benchmark through matching software. The track detector uses the track control network control benchmark to collect the geometric state data of the track for use by the track maintenance department. Therefore, before the transformation and upgrading of existing railways, the measurement and setting of measurement and control benchmarks is an important basis for subsequent work.

[0003] At present, the survey and control benchmarks of existing railways are generally surveyed and set up during maintenance windows, and the surveying operation time is relatively short. The survey and setting up of high-level control benchmarks and track control network control benchmarks are collected and completed by two different surveying devices, GNSS receivers and intelligent total stations, respectively. This is time-consuming, cannot be synchronized, has cumbersome procedures, requires more manpower, and has low operating efficiency. Therefore, the survey and setting up of the survey and control benchmarks during operation cannot meet the actual engineering survey requirements. Summary of the invention

[0004] The purpose of the utility model is to provide a measuring prism bracket adapter device to at least solve the problems that the current measurement and control benchmark surveying and setting requires separate total station and GNSS reception measurements, which is time-consuming, cannot be operated synchronously, has cumbersome procedures, requires a large amount of manpower, and has low operating efficiency.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

The design structure is compact, the manufacturing cost is low, and the prism bracket is highly practical.

[0021] 3. The fixing bolts in the middle of the rotating support platform of the utility model are tightly connected with the fixing bolt holes on the support plate to ensure that the center of the measuring prism bracket is consistent with the center of the GNSS receiver, so that the measurement control reference remains unique.
