Description

Technical Field

[0001] The invention belongs to the technical field of fixing brackets, and in particular relates to a fixing bracket for a surveying and mapping instrument. Background Art

[0002] Surveying and mapping instruments are instruments and devices designed and manufactured for surveying and mapping operations for data collection, processing, output, etc. They are widely used in the planning and design, construction and management stages of engineering construction, as well as in geological exploration, astronomical research and other fields. The following are commonly used: 1. The theodolite used to measure horizontal and vertical angles, which consists of a telescope, a horizontal and vertical degree disk, and a base. It can be further subdivided into vernier theodolites, optical theodolites, and electronic (automatic display) theodolites; 2. A flatbed instrument mainly used for manual ground surveying and mapping of large-scale topographic maps, which consists of an alidade, a flat plate, and a bracket. An electromagnetic wave distance measuring device is attached to the alidade to make the operation more convenient and quick; 3. An electromagnetic wave distance meter that uses electromagnetic waves to measure the distance between two points is small, lightweight, and highly accurate, with a measuring range of 5 to 2 The rangefinder with a range of 0 kilometers is called a medium-range rangefinder, and the range within 5 kilometers is called a short-range rangefinder; 4. A total station that combines an electronic theodolite, an electromagnetic wave rangefinder, a microcomputer, etc., and can quickly perform multifunctional distance measurement, angle measurement, calculation, recording, etc. It is suitable for engineering surveying and large-scale topographic surveying. It can accurately measure the angle between horizontal and vertical lines of sight and the slant distance, and calculate the position of the target point in the instrument coordinate system; 5. A gyrotheodolite that combines a gyroscope and a theodolite to determine the true azimuth; 6. A laser measuring instrument equipped with a laser transmitter, which uses the advantages of good directionality and small emission angle of the laser beam, is used in engineering surveying such as large-scale building construction, ditches, and tunnel excavation. Common laser measuring instruments include laser collimators, laser plumb lines, laser theodolites, laser levels, and laser planes.

[0003] Currently, most of the fixing devices for surveying and mapping instruments are tripods, which can meet the needs of general routine measurements. However, in special areas such as closed tank areas, since the areas are enclosed by high walls, tripods cannot be set up, and the normal use of surveying and mapping instruments cannot be met. Therefore, a fixed bracket is needed that can meet the use needs of surveying and mapping instruments in special areas such as closed tank areas. Summary of the invention

[0004] The purpose of the present invention is to propose a surveying and mapping instrument fixing stand to solve the problem that in special areas such as closed tank areas, since the areas are closed by high walls, tripods cannot be set up and the normal use of surveying and mapping instruments cannot be met. The fixing stand can meet the use requirements of surveying and mapping instruments in special areas such as closed tank areas, and the overall operation is convenient and easy to use. In order to achieve the above-mentioned purpose, the technical solution provided by the present invention is: a surveying and mapping instrument fixing bracket, comprising a support plate, an instrument fixing bolt is fixed at the top center of the support plate, and adjustment plates are movably arranged at both ends of the bottom of the support plate, and fixing screws are threadedly connected to the two adjustment plates. When in use, the distance between the two adjustment plates is adjusted to a suitable size, and then they are clamped on the wall or other objects such as plates, the adjustment plates are fixed by the fixing screws, and then the surveying and mapping instrument is installed and fixed on the instrument fixing bolts to achieve the installation of the surveying and mapping instrument. The overall structure of the fixing bracket is simple and easy to use. It can meet the use requirements of surveying and mapping instruments in special areas and has a good overall use effect.

[0005] Furthermore, a connecting hole is opened on the support plate, and an adjusting plate fixing bolt is arranged in the connecting hole. After the adjusting plate fixing bolt passes through the connecting hole, the adjusting plate is fixed to the bottom of the support plate, and the adjusting plate is fixed by the adjusting plate fixing bolt.

[0006] Furthermore, the connecting hole is a long hole, through which the adjusting plate can be adjusted.

[0007] Furthermore, the adjustment plate is L-shaped, one side of which is in contact with the bottom of the support plate, and the other side is perpendicular to the support plate.

[0008] Furthermore, the fixing screw is threadedly connected to one side of the adjusting plate which is perpendicular to the supporting plate.

[0009] Furthermore, the two adjustment plates are arranged symmetrically.

[0010] Furthermore, a locking nut is threadedly connected to the fixing screw, and the locking nut abuts against the adjustment plate. The locking nut can enhance the anti-loosening effect of the fixing screw.

[0011] Furthermore, a shock-absorbing pad is provided on the top of the support plate, and the surveying and mapping instrument can be protected by the shock-absorbing pad.

[0012] It can be seen from the above technical solutions that the present invention has the following advantages: The installation of the surveying and mapping instrument is achieved by adjusting the distance between the two adjustment plates to an appropriate size, then clamping them on a wall or other plate or other object, fixing the adjustment plates with fixing screws, and then installing and fixing the surveying and mapping instrument on the instrument fixing bolts. The overall structure of the fixing bracket is simple and easy to use. It can meet the use requirements of the surveying and mapping instrument in special areas and has a good overall use effect.
