Automatically levelled theodolite device

Abstract

The invention discloses an automatically levelled theodolite device. The automatically levelled theodolite device comprises a theodolite body and a support, wherein the support comprises a suspension arm and a theodolite body levelling and centering mechanism, the theodolite body levelling and centering mechanism comprises a horizontal fine turning component the bottom of which is connected with the tail end of the suspension arm, as well as a gravity pendulum bob, the horizontal fine turning component is connected with the gravity pendulum bob in a manner of holding a spherical pendulum head of the gravity pendulum bob by virtue of multiple extending downward ball claws which are arranged on the working platform of the horizontal fine turning component, a locating component which can fix the position of the spherical pendulum head is arranged on each ball claw, the gravity pendulum bob also comprises a conical pendulum body, the gravity center of the conical pendulum body is located on the central axis of the conical pendulum body, the vertebral point of the conical pendulum body is arranged downward and is provided with an external screw thread structure, a screw hole matched with an external screw thread structure is formed in the top of the theodolite body, and the central axis of the screw hole is coincided with the vertical axis of the theodolite body. The automatically levelled theodolite device has the advantages that automatic levelling and locating can be realized, and centering is convenient, so that operation is relatively easy and relatively conveniently.

Description

technical field [0001] The invention relates to a theodolite, in particular to an automatic leveling theodolite device. Background technique [0002] Theodolite is an instrument designed to measure horizontal and vertical angles based on the principle of angle measurement. The traditional theodolite includes a theodolite body and a tripod bracket. The theodolite body is used to measure horizontal and vertical angles. There are two common optical theodolites and electronic theodolites. The tripod bracket is used to support and fix the theodolite. When the theodolite is used, the tripod needs to be bisected into triangles first, so that the head of the stand is roughly flat and the measuring hammer is aligned with the center of the measuring station. However, the visual leveling of the traditional tripod is not easy to reach the horizontal error range allowed by the leveling bubble of the theodolite. To achieve leveling and positioning, it must be adjusted repeatedly to meet ...

AI Technical Summary

Problems solved by technology

However, the visual leveling of the traditional tripod is not easy to reach the horizontal error range allowed by the theodolite level bubble. To achieve leveling and positioning, it must be adjusted repeatedly to meet the installation and operation requirements. For the test environment with complex terrain, the leveling and positioning of theodolite is more difficult.

[0003] In order to solve the above problems, the Chinese patent "An Automatic Leveling and Gyro Orientation and Sighting Device" (201310241158.3) discloses a linear motor that uses an electronic level to control the supporting leveling base to achieve the theodolite leveling, but the electronic leveling method requires With more complex control circuits and more precise control components, the instrument is easily damaged, and the electrical signal is easily interfered, which affects the leveling accuracy

Chinese patent (ZL201120048395.4) "A Theodolite Without a Leveling Device" discloses a device that controls leveling through a complex observation and aiming unit and a calculation processing unit. There is also a complex structure of the leveling device that uses sophisticated electronic control components. , easy to damage and affect the use, and the electrical signal is susceptible to interference, which affects the problem of leveling accuracy
