Large-dip-angle self-leveling device

Abstract

The invention relates to a large-dip-angle self-leveling device. The large-dip-angle self-leveling device comprises a mounting base platform arranged on a mounting stand column and a supporting cylinder connected with the mounting base platform. A leveling plate is arranged at the top of the mounting base platform, and a leveling platform is arranged on the leveling plate. A spirit bubble indicator and a control circuit board are arranged on the leveling platform. A balance weight connecting rod is arranged in the supporting cylinder, one end of the balance weight connecting rod is connected with the leveling platform, and the other end of the balance weight connecting rod is connected with a balance weight. A four-core cable penetrates through the balance weight connecting rod and the balance weight. Observation windows are symmetrically arranged at the lower part of the supporting cylinder. A melting pool is arranged at the bottom in the supporting cylinder, and special hot melt adhesive is contained in the melting pool. A heating pipe is inserted into the special hot melt adhesive and is connected with the balance weight through an epoxy resin heat insulation sleeve. One end of the four-core cable is connected with the control circuit board, and the other end is connected with the heating pipe. The large-dip-angle self-leveling device is low in cost, high in leveling reliability and suitable for installation of instruments and equipment needing to be kept in a horizontal state in the working process of the measuring instruments.

Description

technical field [0001] The invention relates to a leveling device, in particular to a self-leveling device with a large inclination angle. Background technique [0002] The average altitude of the Qinghai-Tibet Plateau is more than 4,000 meters, and the annual average temperature in the hinterland of the plateau is below 0°C. The natural geographical and climatic conditions are harsh, and the engineering geological conditions are complex. The construction of the transportation hub from Qinghai to Lhasa is a lifeline project connecting the inland and Tibet. Subgrade settlement deformation is an important index to evaluate the stability of Qinghai-Tibet highway and railway engineering. For a long time, artificial level monitoring, as the most basic monitoring method for field deformation monitoring, is also the most reliable at this stage, and at the same time, it is also the most expensive monitoring method. With the advancement of science and technology, deformation monito...
