Automatic leveling device based on joint bearing and application thereof

Abstract

The invention relates to the technical field of leveling devices, in particular to an automatic leveling device based on a joint bearing and application thereof. The automatic leveling device comprises a bracket, a mounting base, a vertical shaft and a horizontal disc, wherein the mounting base is arranged on the bracket; the joint bearing is arranged in the mounting base; the lower part of the vertical shaft is fixedly inserted in the joint bearing; a connecting piece is arranged in the center place of the lower end surface of the vertical shaft; the other end of the connecting piece is connected with a counterweight block; the upper end of the vertical shaft is vertically and fixedly connected with the horizontal disc; multiple positioning pieces are arranged on the mounting base, are supported on the bottom surface of the horizontal disc in a height adjusting manner, and consist of bolts and nuts; the bolts are inserted in or in threaded connection into positioning holes formed in the mounting base; and the nuts are in threaded connection to the bolts, and are butted against the upper surface of the mounting base. The automatic leveling device is reasonable in design, simple in structure and convenient for use; and no matter which bearing surface is provided with the mounting base and if the mounting base is horizontally mounted, the horizontal disc can be always automatically located in a horizontal state.

Description

technical field [0001] The invention relates to the technical field of leveling devices, in particular to an automatic leveling device based on joint bearings and its application. Background technique [0002] With the development of technology in the technology industry, many measuring instruments (such as range finders, theodolites, etc.), electronic devices (such as projectors, scanners, etc.), and platforms for installing weapons during shooting training, etc., need to be placed On a horizontal plane, but in many cases the bearing surface of the bearing body carrying these instruments is not flat, or some instruments need to be used frequently in different locations, so the state of the bearing surface of the bearing body is constantly changing, and even some instruments It is necessary to work on a moving carrier. The method of making them level in the prior art is usually to manually adjust them and judge them to be in a horizontal state based on experience. This metho...

[0002] With the development of technology in the technology industry, many measuring instruments (such as range finders, theodolites, etc.), electronic devices (such as projectors, scanners, etc.), and platforms for installing weapons during shooting training, etc., need to be placed On a horizontal plane, but in many cases the bearing surface of the bearing body carrying these instruments is not flat, or some instruments need to be used frequently in different locations, so the state of the bearing surface of the bearing body is constantly changing, and even some instruments It is necessary to work on a moving carrier. The method of making them level in the prior art is usually to manually adjust them and judge them to be in a horizontal state based on experience. This method is not only inaccurate, but also time-consuming and laborious. Once the carrier is replaced body, it must be readjusted, which is inconvenient to use
