Description

A support frame for surveying instrument

Technical Field

The utility model relates to a geological survey technical field, more specifically relate to a support frame for surveying instrument.

Background

The surveying and mapping technology is used for measuring land and surveying and mapping various maps for planning and managing in urban and rural construction planning, utilization of national and local resources, environmental protection and other works; in geological exploration, mineral development, water conservancy, traffic and other constructions, control measurement, mine measurement, route measurement and topographic map drawing are carried out for geological survey and various building design and construction.

The surveying instrument is one of the common devices used in geological exploration and geological engineering construction, and the placement stability and the tangential angle of the surveying instrument directly influence the accuracy of the final measurement data of the surveying instrument. In the existing geological mapping bracket, the levelness and the verticality of the mirror bracket are difficult to adjust, so that the accuracy is reduced during mapping; the fixing performance is poor, and when the support is adjusted, the positions of every two support rods cannot be effectively fixed, so that the support rods are easy to slide relatively, and the surveying and mapping precision is reduced; the stability of the bracket is poor, and the area between the bracket rod and the ground is small when surveying and mapping is carried out, so that the bracket is easy to slide; the damping performance is poor, resulting in a reduced degree of mapping.

SUMMERY OF THE UTILITY MODEL

The utility model discloses a realize above-mentioned purpose and specifically adopt following technical scheme:

the utility model provides a support frame for surveying instrument, includes the disc, articulates the supporting leg in the disc bottom and fixes the dead lever in the disc bottom, its characterized in that: the supporting leg is loop bar structure, loop bar structure from the top down is interior loop bar one, outer loop bar and interior loop bar two in proper order, outer loop bar side outside is equipped with the knob, the inside gear that is equipped with in interior loop bar side, knob and gear fixed connection, interior loop bar one are opened flutedly in gear position department axial, and interior loop bar one is equipped with the rack with the inside side that the gear is adjacent, rack and gear engagement, interior loop bar two passes through damping spring with outer loop bar and links to each other, the dead lever bottom is equipped with rotatable axis of rotation, and the axis of rotation is connected with the semiconductor laser, and the dead lever is perpendicular with the disc surface, and the dead lever is located the disc centre of a circle department. And a mark for marking the horizontal position is arranged on one side surface of the inner loop bar.

Furthermore, the bottom of the inner sleeve rod II is provided with a conical bottom foot.

Furthermore, the upper surface of the disc is connected with a fixed seat for installing a surveying instrument through a support rod.

Furthermore, the supporting leg has 3, and the supporting leg all sets up and the eccentric department of disc, and the supporting leg is equipped with spacing piece with disc articulated position department.

The utility model discloses a theory of operation does:

at first the supporting leg is opened and is steadily propped up the support frame subaerial, installs the surveying instrument on the fixing base at support frame top, if ground softer can insert ground reinforcing stability with the footing, later begin to adjust the level to the support frame:

and opening the semiconductor laser, and rotating the rotating shaft to enable the emitted laser to be aligned with the horizontal mark of one of the supporting legs. Rotating the rotating shaft to enable the laser to shoot to the other supporting leg, and if the laser just falls on the horizontal mark, adjusting the next supporting leg; if the laser does not fall on the horizontal mark, the knob is rotated to adjust the height of the supporting leg, so that the laser falls on the horizontal mark. And after the three supporting legs are adjusted, observing whether the surveying instrument is horizontal or not, and if not, adjusting by using a leveling device of the surveying instrument.

The utility model has the advantages as follows:

1. the utility model discloses whether utilize laser to aim at predetermined horizontal mark and judge whether the support frame is level, later adjust the level through setting up adjusting device on the supporting leg again, avoided the support frame too to incline through the level of adjusting the support frame in advance like this and lead to the unable leveling of surveying instrument, influence measured data.

2. The length of the supporting leg is adjusted through the matching of the gear and the rack, and the adjusting precision is high.

3. The supporting leg is equipped with spacing piece with disc articulated position department, has strengthened the stability of support frame.

4. The footing of supporting leg is the toper for the carriage can firmly be embedded in the soft environment of soil texture, avoids the carriage to stand the condition of easily falling on the soft soil.

5. The supporting leg is provided with damping spring inside, has reduced the supporting leg and has propped up the stress of in-process, has increased the life-span of support frame.
