Description

Prism support for accurate and rapid lofting of total station

Technical Field

The utility model relates to a mapping equipment technical field, more specifically say, relate to a prism support that is used for accurate quick laying out of total powerstation.

Background

In engineering survey application, the plane position of a building (structure) designed by drawing paper needs to be calibrated in the field, the work is called lofting, lofting by adopting a total station is a common means in engineering practice, and lofting by adopting the total station is generally carried out in two modes, namely polar coordinate lofting and coordinate lofting, wherein the coordinate lofting is the most common mode.

When the total station coordinate method is adopted for lofting, firstly, the station is arranged and oriented, after the coordinates of the point to be lofted are input, the position of the lofted point is obtained, according to the direction of collimation of the total station, the lofting personnel is instructed to arrange the lofting prism rod in the sight line direction of the total station to measure the distance between the prism and the measuring station, obtaining lofting distance deviation according to the theoretical distance between a lofting point and a survey station, enabling lofting personnel to hold a prism rod to move back and forth along the sight line direction of the total station until the distance deviation is zero, in order to accurately determine the position of the lofting point, the total station needs to measure the distance from the prism to the measuring station once when the lofting personnel moves the position, and the lofting personnel can report the distance deviation of the lofting point, and the lofting personnel can repeatedly adjust the moving direction and the moving distance according to the instruction, and the level of the bubbles on the prism rod is kept, a great deal of time is wasted in the process, and the lofting precision is influenced.

SUMMERY OF THE UTILITY MODEL

To the problem that exists among the prior art, the utility model aims to provide a prism support for accurate quick lofting of total powerstation, its portable, simple structure, when adopting total powerstation lofting, the lofting personnel of handheld prism pole roughly confirm treat the lofting point position after, settle the utility model discloses prism support, adjust the expansion bracket leg and make the base set level, insert the prism pole in the prism pole buckle, rotate the rotating head and make the prism aim at the total powerstation sight, according to the lofting point skew distance that total powerstation operating personnel given, adjust the length of expansion rod, make the accurate quick lofting point position of waiting of being in of prism pole, effectively practiced thrift lofting time, guarantee the precision of lofting point simultaneously.

In order to achieve the above object, the utility model provides a following technical scheme:

the utility model provides a prism support that is used for accurate quick laying out of total powerstation, includes expansion bracket leg, base, connecting rod, rotating head, telescopic link, its characterized in that: the connecting rod rigid coupling is directly over the base, the rotating head can the extrapolation in the connecting rod to can rotate, open the rotating head side has the bolt hole and is provided with fastening bolt.

Preferably, the base is provided with round air bubbles, and the base is flatly placed by adjusting the telescopic bracket legs.

Preferably, the telescopic rod is multi-section telescopic, each section of telescopic rod is provided with length scales, the minimum scale is millimeter, and the total length of the telescopic rod after being completely stretched is 50 cm.

Preferably, the swivel head is rotatable 360 degrees about the connecting rod.

Preferably, the tail end of the telescopic rod is provided with a prism rod buckle, and the buckle is made of plastic materials and has certain elasticity.

Preferably, the prism rod buckle is a U-shaped opening, the size of the opening is consistent with the diameter of the lofting prism rod, and the prism rod can be clamped in the U-shaped opening.

The utility model has the advantages that:

1. the total station positioning device is simple in structure, the direction of the prism is adjusted through the rotating head to align to the sight of the total station, the position of a to-be-lofted point can be quickly found according to the scale on the telescopic rod, and lofting time is saved.

2. The scale on the telescopic rod is accurate to millimeter, and the plane position accuracy of the lofting point can be ensured.

3. The operation method is simple, non-professional personnel can assist in lofting, and the operation is convenient.
