Profile measuring instrument platform stabilizing device for geological survey

Abstract

The invention relates to the technical field of geological survey auxiliary equipment, in particular to a profile measuring instrument platform stabilizing device for geological survey. A bearing c is arranged on a supporting platform, an adjusting sleeve is arranged in the bearing c, an internal thread is arranged in the adjusting sleeve, and a threaded column with an external thread is arranged at the bottom of a placing frame, so that the internal thread and the external thread are matched and connected. The threaded column can be screwed into the adjusting sleeve, the height of the threaded column is adjusted by rotating and turning the adjusting sleeve, meanwhile, the bottom of the adjusting sleeve is hollowed out, the threaded column can penetrate through the adjusting sleeve, the height adjustable range is enlarged, and fine adjustment of height adjustment is achieved through adjusting arrangement of a threaded structure; and threaded engagement enhances the stability.

Description

technical field [0001] The invention relates to the technical field of geological survey auxiliary equipment, in particular to a platform stabilization device for a profile measuring instrument used in geological survey. Background technique [0002] Geological profile measurement is a section measurement work carried out along the exploration line or a given direction according to the requirements of geological exploration, including profile alignment measurement, profile control measurement, topographic profile measurement, profile point measurement, profile calculation, and profile drawing. [0003] At present, a lot of research has been done on the geological exploration profile measurement equipment in the prior art, but it mainly focuses on the research and improvement of the stabilizing device at the bottom of the measuring instrument. The supporting leg is movable and hinged, one end of the supporting leg is fixedly connected with a support plate, the bottom of the s...

Problems solved by technology

It can be seen that the device utilizes the clamping plate at the top of the threaded casing to engage the lifting rod, and utilizes the relative thread sliding between the threaded sleeve and the column to realize the way that the clamping plate lifts the lifting rod or pulls down the lifting rod. The lifting rod moves up and down in the movable groove to achieve the purpose of height adjustment; however, this structure makes the clamping plate and the lifting rod form a ring connection at the contact point, which makes the height adjustment poor in stability. The height space between matching with the column is limited, resulting in the limitation of the adjustable height range, and it is difficult to fully adjust to the minimum volume state, resulting in a large volume during storage and transportation; moreover, when installing the measuring instrument , needs to be fixed on the mounting plate with bolts, resulting in cumbersome installation process, low installation efficiency, and cumbersome disassembly process

Another example: Patent No. 202021342858.3 discloses the body of the measuring instrument, the fixed sleeve, the telescopic block, and the limit ring; the stable installation of the support rod is realized by using the limit ring, and the height adjustment is realized by using the fixed sleeve and the telescopic block, but the fixed The support block is inserted into the through hole between the sleeve and the telescopic block to achieve fixation. At the same time, the support block is squeezed out by a pull rod to realize the detachment and sliding between the fixed sleeve and the telescopic block to achieve height adjustment; and telescopic The block is located at the bottom, and the fixed sleeve is located at the top, so that the telescopic block is inserted into the fixed sleeve to achieve height adjustment, which not only makes the adjustable height range limited by the height of the fixed sleeve and the height of the telescopic block, but also cannot be realized. Fine-tuning, it is difficult to meet the requirements of the measurement process, the height of the micro-adjustment according to the needs, resulting in low measurement accuracy and poor stability
