Description

Technical Field

[0001] This utility model relates to the field of total station prism support technology, and in particular to a prism support base used when utilizing the elevation difference measurement auxiliary function of a total station. Background Technology

[0002] In mountainous construction sites with significant elevation differences, when leveling earthwork, it is necessary to first measure the elevation difference of the entire site in order to balance the earthwork. If GPS measurement is used, the error will be very large. If a level instrument is used, the measurement workload will be too large. A total station has an auxiliary function for measuring elevation differences, and this auxiliary function can be used when measuring elevation differences in construction sites with significant elevation differences in mountainous areas.

[0003] In the prior art, patent application number 201120028943.7 provides a total station coordinate rapid positioning device. This utility model includes a bracket and a universal slide rod. The bracket is a triangular bracket with a rotating base mounted on it. A gear-type rotating handle and a level tube are fixedly mounted on the rotating base. The universal slide rod passes through the rotating base and connects to the bracket. The universal slide rod is composed of a threaded steel rod and a parallel steel pipe. A counterweight and a prism base are movably mounted on the universal slide rod. A gear is fixedly mounted in the center of the universal slide rod, and the gear meshes with the gear of the gear-type rotating handle. This utility model has a reasonable structural design and is easy to operate. By rotating the handle, the prism and counterweight can be adjusted simultaneously, avoiding lateral deviation and reducing measurement errors. This effectively improves the speed of tripod setup, work efficiency, and measurement quality.

[0004] However, the bottom of the support of the existing total station prism is pointed. The elevation difference measurement of the total station is based on the elevation of the pointed bottom of the total station prism support. Since the ground soil at the construction site in the mountainous area is relatively soft and of different types, the depth to which the pointed bottom of the prism support is inserted into the soil will be inconsistent when measuring the elevation difference at different locations, which directly leads to errors in the elevation difference measurement of the soil being measured. Utility Model Content

[0005] The purpose of this invention is to provide a prism support base for use when using the elevation difference auxiliary function of a total station, so as to solve the problem of different insertion depths of the bottom end of the prism support into the soil in existing total stations.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0007] This utility model provides a prism support base for using the elevation difference measurement auxiliary function of a total station. The total station support includes a total station tripod and a prism vertical support rod, the lower end of which is a center point. The prism support base includes a base shell disposed on the center point.

[0008] The base housing contains a wedge-shaped block that is adapted to contact the side of the tip; and a positioning clamping block I and a positioning clamping block II are also provided in the base housing and above the wedge-shaped block.

[0009] The positioning clamping block I and the positioning clamping block II are respectively provided with semi-circular grooves that are adapted to the outer diameter of the vertical support rod of the prism;

[0010] The base housing is also provided with set screws for adjusting the distance between the positioning clamping block I and the positioning clamping block II.

[0011] In this embodiment, the base housing is further described as a square box.

[0012] In this embodiment, the wedge block further includes wedge block I and wedge block II disposed within the base housing and abutting against the side of the tip.

[0013] In this embodiment, a semi-circular groove I is provided in the positioning clamping block I, and a semi-circular groove II symmetrical to the semi-circular groove I is provided on the positioning clamping block II.

[0014] In this embodiment, a screw hole is further provided on the side wall of the base housing to facilitate the passage of the set screw; the set screw includes set screw I connected to the positioning clamping block I and set screw II connected to the positioning clamping block II.

[0015] Compared with the prior art, the beneficial technical effects of this utility model are as follows:

[0016] In this invention, a box-shaped base is added to the bottom tip of the total station prism support leg, so that the tip is always in contact with the box-shaped base plate. This overcomes the problem that the tip is easy to insert into the ground soil when measuring elevation, and ensures that the measured ground and the measurement reference tip of the total station are always in the same position, thus ensuring the accuracy of elevation measurement.

The total station support includes a total station tripod 1 and a prism vertical support rod 2. The lower end of the prism vertical support rod 2 is a tip 4. The prism support base includes a base housing 5 installed on the tip 4. The prism vertical support rod 2 is a height-adjustable structure.

[0023] refer to Figure 2 The base housing 5 is equipped with a wedge-shaped block that is adapted to contact the side of the tip 4; a positioning clamping block I9 and a positioning clamping block II10 are also installed in the base housing 5 and above the wedge-shaped block. In this embodiment, the base housing 5 is a square box, and the wedge-shaped block includes wedge-shaped block I6 and wedge-shaped block II7 installed in the base housing 5 and in contact with the side of the tip 4; wedge-shaped block I6 and wedge-shaped block II7 are respectively located on the left and right sides, and a tip-top contact surface 8 is provided on the bottom plate in the base housing 5 between them as a tip support surface.

[0024] refer to Figure 3 The positioning clamping block I9 and the positioning clamping block II10 are respectively provided with semi-circular grooves that are adapted to the outer diameter of the vertical support rod 2 of the prism; the base housing 5 is also equipped with set screws for adjusting the distance between the positioning clamping block I9 and the positioning clamping block II10 respectively.

[0025] A semi-circular groove I11 is formed inside the positioning clamping block I9, and a semi-circular groove II12 symmetrical to the semi-circular groove I11 is formed on the positioning clamping block II10. A screw hole is formed on the side wall of the base housing 5 to facilitate the passage of the set screw; the set screw includes a set screw I13 connected to the positioning clamping block I9 and a set screw II14 connected to the positioning clamping block II10; thereby clamping the base housing 5 and the lower end of the prism vertical support rod 2 tightly, making the lower end of the prism vertical support rod 2 and the base housing 5 form a whole, realizing accurate measurement of ground elevation.

[0026] The steps for measuring elevation differences using this invention are as follows:

[0027] The first step is to calibrate the measurement accuracy of the total station before construction.

[0028] The second step is to click on the prism settings in the total station elevation measurement. The height of the prism rod is set in the instrument settings.

[0029] The third step is to set up the prism at the control point, place the base housing 5 at the bottom of the vertical support rod 2 of the prism on the ground at the measurement point, and use the total station's height difference measurement auxiliary function to measure;

[0030] Step 4: At this point, the measured data is set to zero, meaning the relative elevation is zero.

[0031] Step 5: Locate the highest point that provides a view of the entire site and use it as the reference point for the total station measurement;

[0032] Step 6: Next, use a total station to measure. The data displayed by the instrument at this point is the relative elevation.
