Instrument supporting frame for marine surveying and mapping

Abstract

The utility model relates to the technical field of instrument supporting frames, and discloses an instrument supporting frame for marine surveying and mapping, which comprises a bracket disc, and bracket supporting legs are hinged to the side edge of the bracket disc and are used for supporting after being unfolded. A vertically-through spherical sleeve is fixedly arranged in the middle of the support disc, the inner wall of the spherical sleeve is a spherical surface, a self-swinging ball body is hinged to the inner spherical surface of the spherical sleeve, and a support fixing seat used for fixing a surveying instrument is fixedly arranged at the upper end of the self-swinging ball body. After the support leg is installed on the uneven ground, the gravity swing body enables the self-swing ball to deflect relative to the spherical sleeve through the gravity effect so as to keep the swing rod perpendicular all the time, then it is guaranteed that the support fixing base and the surveying instrument installed on the support fixing base are kept in the horizontal state, and the support leg is efficient and simple.

Description

Technical Field

[0001] The utility model relates to the technical field of instrument support frames, in particular to an instrument support frame for marine surveying and mapping. Background Art

[0002] The existing measuring instrument has a bubble level on its support frame. When the measuring instrument is supported on an uneven ground, the length of each support leg is adjusted to make the measuring instrument level. This is very troublesome to adjust, and the visual bubble level has errors and cannot guarantee accurate levelness. Utility Model Content

[0003] The technical problem to be solved by the utility model is: in order to overcome the above problems, a support frame for an instrument for marine surveying and mapping is provided, which solves the above problems.

[0004] The utility model solves the technical problem by adopting the following technical solutions:

[0005] A support frame for an instrument for marine surveying and mapping comprises a support plate, a support leg is hingedly provided on the side of the support plate for supporting after unfolding, a spherical sleeve is fixedly provided in the middle of the support plate and passes through the support plate from top to bottom, and the inner wall of the spherical sleeve presents a spherical surface, a self-swinging sphere is spherically hingedly provided in the spherical sleeve, and a support fixing seat for fixing a surveying and mapping instrument is fixedly provided on the upper end of the self-swinging sphere.

[0006] Preferably, a swing rod is threadedly connected to the lower end of the self-oscillating sphere.

[0007] Preferably, the self-oscillating sphere is a hollow structure.

[0008] Preferably, a gravity pendulum is fixedly provided at the lower end of the pendulum arm, and under the gravity of the gravity pendulum, the pendulum arm is always in a vertical state to ensure that the bracket fixing seat and the surveying instrument installed on the bracket fixing seat are in a horizontal state.

[0009] Preferably, the gravity pendulum body is a hollow structure, and a water storage chamber is provided in the gravity pendulum body. After water is added to the gravity pendulum body, the gravity is increased so that it can effectively play a suspending role, and water is not added at ordinary times to reduce the weight.

[0010] Preferably, a locking screw adjuster is provided on the side threaded connection of the bracket plate, and when the self-oscillating sphere is straightened by the weight pendulum, the self-oscillating sphere is clamped and fixed by twisting the locking screw adjuster.

[0011] The advantages and positive effects of the utility model are: when the bracket support is installed on an uneven ground, the gravity pendulum causes the self-swinging sphere to deflect relative to the spherical sleeve through the action of gravity, thereby keeping the pendulum rod always vertical, thereby ensuring that the bracket fixing base and the surveying instrument installed on the bracket fixing base remain in a horizontal state, which is efficient and simple.
