Abstract

The utility model provides a detachable location ball target fixing device, is including burying underground with the underground pile foundation, and the pile foundation is the shape of falling T, and the concrete mound is connected at the top of pile foundation, and the front stall at the top of concrete mound is connected with the front stall quarter butt between two parties, and a back row stock is respectively connected on the both sides of back row, the top of front stall quarter butt, back row stock respectively connect a prism through the slot buckle. The device is arranged beside a relatively important building or near a building or a bridge, a tunnel and other projects which are being built and often need to be measured by a three-dimensional laser scanner. And after the target balls are installed, respectively positioning the three handle balls by using a total station, and recording the positions on the concrete pier. When the three-dimensional laser scanning is carried out, the measurement can be started only by placing the target ball, the coordinates of the target ball are the same in each measurement, and the total station is not required to be repositioned.

Description

Detachable location ball target fixing device

Technical Field

The utility model relates to a fixing device for a detachable positioning ball target.

Background

Today that surveying and mapping technique is perfect day by day, emerging three-dimensional laser scanning measurement is entering the survey and drawing field secretly, in building deformation monitoring, three-dimensional laser scanning passes through certain frequency transmission laser signal, meet the obstacle and can reflect the acceptance device who feeds back to three-dimensional scanner when the signal, every second scanner will scan million rank's point cloud, 360 all standing, carry out the omnidirectional scanning to the building, need three to the spherical mark target more than three to carry out space location simultaneously, the accuracy of scanning spatial position has been decided to the precision of mark target, consequently, the erection of spherical mark target has played huge effect in the scanning.

Since spatial positioning is always the most critical step, the spherical target is erected by centering the prism rod, and then the scanner identifies the spatial position by the position of the spherical target. In three-dimensional laser scanning, the position of a spherical target frame station generally changes along with the actual situation, but the frame stations at different positions bring many accidental errors, the errors caused by the accidental errors are gradually increased due to the errors, a centering rod lacks certain stability in the process of erecting the existing ball target by the middle rod, and many accidental errors are generated due to the situation of an operator under the actual situation, so that the scanning result is influenced. In addition, in the actual measurement process, a large amount of manpower and time are consumed for positioning the target ball, and the device can greatly shorten the measurement time in the engineering.

Disclosure of Invention

In order to overcome the defects in the prior art, the utility model provides a detachable positioning ball target fixing device.

The utility model provides a technical scheme of above-mentioned problem is:

the utility model provides a detachable location ball target fixing device which characterized in that: including burying underground pile foundation 5, pile foundation 5 is the shape of falling T, and concrete pier 1 is connected at pile foundation 5's top, and the front stall at concrete pier 1's top is connected with front stall quarter butt 4 between two parties, and a back row long pole 3 is respectively connected on the both sides of back row, front stall quarter butt 4, back row long pole 3 top respectively through slot buckle connection prism 2.

The front row of short rods 4 and the rear row of long rods 3 are both buried in the concrete pier 1 and adopt carbon fiber rods.

The length, width and height of the pile foundation 5 are 120cm × 120cm × 80cm, and the length, width and height of the concrete pier 1 are 80cm × 40cm × 100cm 35100 cm.

The utility model discloses a be used for with the unit of ground connection and be used for with the unit of spherical mark target connection, set up in more important building and often need near engineering such as the building limit that three-dimensional laser scanner measured or the bridge that is building, tunnel.

The beneficial effects of the utility model are that:

the utility model has simple structure, firmness and durability, can realize the fixed observation of the scanning ball target, has more convenient operation, better fixing effect, strong adaptability and wide application range; the stability is enhanced by arranging the pile foundation 5, and the carbon fiber rods are buried in the concrete connecting column, so that the ball target is not easy to disturb; meanwhile, the position of the ball target is fixed, so that the ball target does not need to be placed independently in three-dimensional scanning observation, and the space positioning can be directly carried out according to the space coordinate of the known ball target.

Detailed Description

The technical scheme of the utility model is further explained below with the attached drawings.

A removable positioning ball target fixture includes a unit for attachment to the ground and a unit for attachment to a ball target.

The utility model provides a detachable location ball target fixing device, is including burying underground with underground pile foundation 5, pile foundation 5 is the shape of falling T, and concrete pier 1 is connected at the top of pile foundation 5, and the front stall at the top of concrete pier 1 is connected with front stall quarter butt 4 between two parties, and a back row long pole 3 is respectively connected on the both sides of back row, front stall quarter butt 4, the top of back row long pole 3 respectively through slot buckle connection prism 2.

The front row of short rods 4 and the rear row of long rods 3 are different in length, so that the measuring device is suitable for measuring requirements of different terrains and different angles.

The concrete pier is poured on the inverted T-shaped independent pile foundation, and three long and short carbon fiber rods are respectively installed above the inverted T-shaped independent pile foundation. The slot buckle of carbon fiber pole top for installing three-dimensional laser scanner target ball utilizes the total powerstation to fix a position three respectively the ball after the target ball installation is accomplished to the record is on the concrete pier. When the three-dimensional laser scanning is carried out, the measurement can be started only by placing the target ball, the coordinates of the target ball are the same in each measurement, and the total station is not required to be repositioned.

The embodiments described in this specification are merely illustrative of implementations of the inventive concepts, and the scope of the invention should not be considered limited to the specific forms set forth in the embodiments, but rather the scope of the invention includes equivalent technical means that can be conceived by those skilled in the art based on the inventive concepts.
