The present invention relates to a tripod protection device for geodetic survey, in more detail, it is possible to adjust the micro-angle of the surveying equipment from the state that is firmly fixed to the surveying equipment and the rotating plate to eliminate facial expression errors, external shock or vibration In addition, the fixed state of the surveying equipment and the rotating plate is maintained firmly, and the tripod protection device for geodetic surveying to improve the safety and reliability of the equipment by preventing the fall of the surveying equipment during the expression work.

In general, cadastral surveying is the work of surveying the land surface, underground, and aerial of land throughout the country and storing it as a record in the state or an institution authorized by the state. This is a task that must be performed without any error to establish a complete disclosure function.

The purpose of such cadastral surveying is not only to prevent damages of the trading partners in land transactions between individuals based on such cadastral surveying, but also to ensure that the registration of land has legal effect and to provide various types of taxation and It is to be used as a standard of imposition and to be used as technical data for various land regulations necessary for the execution of public plans such as housing site development and housing construction.

Therefore, in cadastral surveying, it is obvious that the accuracy of surveying equipment as well as the accurate surveying of surveyors are of paramount importance.

On the other hand, Korea's cadastral system was launched in 1910 as a land survey project, and the entire country was registered as a pictorial map. As a result, more than 90% of the country's land was still relied on by surveying.

Therefore, cadastral surveying still relies heavily on illustrated surveying operations using surveying equipment such as side plates and optical padodolites, and in order to install such surveying equipment at a height that is easy to operate from the ground, A tripod for fixing is installed.

Such a tripod is to allow the position of the surveying equipment to be fixed in a horizontal state at a predetermined height, and the configuration thereof is generally a seating plate on which the surveying equipment is mounted and fixed, a body supporting the seating plate, and the It is provided with three legs that allow the body to be horizontally spaced apart from the ground by a predetermined height.

Here, the seating plate is provided with a clamp, the clamp is formed with a projection protruding vertically at one end, the projection is inserted into a groove formed in the surveying equipment in advance to rotate the surveying equipment and the seating plate It is a structure to fasten.

In addition, the seating plate is firmly fixed to the body, and prevents the surveying equipment fixed to the seating plate from moving.

In addition, the legs are arranged in a triangular reference to the body, the hinge is coupled to the body so that the height and horizontality of the body is foldable structure.

Therefore, first, the operator opens the tripod legs to secure the tripod to the ground, and then adjust the open angle of the tripod legs or adjust the length of the legs to adjust the height and level of the tripod, the surveying equipment to the tripod To the seat plate.

At this time, the worker grasps the surveying equipment by hand and rotates it slightly to the left and right, and performs the facial expression work to match the direction of the surveying equipment to the center of the pole, and when the expression is completed, the tripod is seated. By rotating the clamp installed on the plate, the surveying equipment is completely fixed to the seating plate.

However, despite the accurate expression, the phenomenon in which the surveying equipment moved finely at the moment of tightening the locking device and had to perform the expression again frequently occurred.

In addition, there is a problem in that the loosening of the clasp occurs structurally, the expression error occurs after a certain time after the expression.

In addition, before the surveying equipment and the seating plate is completely fixed by the clasp, the facial expression work is performed, and during the facial expression work, expensive surveying equipment, such as optical padadeolite, has fallen from the tripod and has been broken.

In addition, when surveying is carried out near roadsides or heavy equipment workshops, which are not structurally robust, the surveying equipment is easily twisted due to the vibration of the ground caused by large vehicles or heavy equipment. There was a problem such as poor accuracy of the survey.

In addition, the conventional tripod for surveying equipment is that the tripod for each surveying equipment is manufactured separately, incompatible with each other, for example, when the optical padodolite work and flat plate work, two tripods must be carried separately in the workplace. There was a problem such as inconvenience.

In order to improve this, Patent No. 0288885 (2001.02.12.) "Tripod for surveying equipment" has been disclosed.

However, since the registered patent is composed of a bed of the lower end of the leg is fixed by the anchor type when fixed to the ground, it helps to achieve a stable fixed structure by preventing fluidity, but because of the point support method, the equilibrium stability falls, If it is not strong, it is easily pushed and blurs the measuring point, resulting in poor surveying.
