The use of suitable support frames can improve the efficiency and accuracy of engineering surveying and mapping, and provide more reliable data support for engineering construction.

[0023] Embodiment 1:

[0024] Based on the technical defects of the existing technology that affect the surveying efficiency because the surveying instrument needs to be vertically calibrated when used on a slope, please refer to Figure 1-Figure 4 The utility model provides a support frame for engineering surveying and mapping. The weight ball 35 is used to drive the center column 34 to be in a vertical state under the action of the universal moving part. This ensures that the surveying and mapping instrument can be in a horizontal state after installation. In this way, there is no need to perform vertical calibration work in subsequent use, which reduces the surveying and mapping time and improves the surveying and mapping efficiency. The utility model comprises an annular seat 1. The bottom of the annular seat 1 is fixedly provided with a bracket assembly 2 that can maintain the overall stability in different terrains. The inner side of the annular seat 1 is provided with a movable assembly 3 that can keep the surveying and mapping instrument in a horizontal state on a slope. The top of the movable assembly 3 is fixedly provided with a base 4, and a fixing assembly 5 is installed on the base 4. The supporting assembly is used to provide support and stabilization for the whole. Then, under the action of the movable assembly 3, the surveying and mapping instrument can automatically maintain a horizontal state after being installed on the support frame through the fixing assembly 5, and then the surveying and mapping work can be carried out.

[0025] When the support frame is placed on the slope, to ensure that the surveying and mapping instrument can be automatically level after installation, please refer to Figure 1 and Figure 2 The movable component 3 includes a universal joint movably connected in the annular seat 1, and a center column 34 is movably connected to the inner side of the universal joint. The top of the center column 34 is fixedly connected to the bottom of the base 4, and a counterweight ball 35 is fixedly arranged at the bottom of the center column 34 for calibrating the base 4 to be in a horizontal state by its own gravity. Under the action of the universal joint, the center column 34 can rotate in any direction, and under the action of the gravity of the counterweight ball 35, the counterweight ball 35 can always keep the center column 34 in a vertical state. After the center column 34 is vertical, the base 4 can automatically remain horizontal, so that the surveying and mapping instrument on the base 4 is in a horizontal state.

[0026] In order to improve the stability of the bracket assembly 2 during support, at least three bracket assemblies 2 are provided and evenly distributed at the bottom of the annular seat 1, so that the bracket assembly 2 can form a triangular support posture after being unfolded, and the support is more stable and not easy to shake.

[0027] To facilitate the stable support of the surveying instrument on the ground, please refer to Figure 1 and Figure 4 The bracket assembly 2 includes a hinge block 21 fixedly connected to the bottom of the annular seat 1, and a support rod 22 is rotatably connected to the hinge block 21. A stopper 23 for limiting the support rod 22 is fixedly provided on the side wall of the hinge block 21. An adjusting screw 24 is threadedly connected to the bottom of the support rod 22, and a base 25 is fixedly provided at the bottom of the adjusting screw 24. When the support rod 22 is unfolded, the support rod 22 can be limited by the block 23, so that the support rod 22 will not continue to move after being unfolded, and the whole can be kept in a supporting state. The height of the base 25 can be controlled by adjusting the screw 24, and when facing a stepped ground or a bumpy ground, the stability of the whole can also be ensured during use.

[0028] When the support assembly 2 is folded, in order to prevent the support assembly 2 from moving, a strap 6 is fixedly provided on the side wall of one of the support rods 22. The strap 6 can bind a plurality of support assemblies 2 together for easy fixation.

[0029] To facilitate the rotation of the center column 34 in any direction, please refer to Figure 2 The universal moving part includes two sliders 1 31, and the two sliders 1 31 are both slidably arranged in the annular groove 11 provided on the inner wall of the annular seat 1. The two sliders 1 31 are respectively fixedly connected to the outer wall of the rotating ring 32. The rotating ring 32 is provided with two movable holes 321, and the inner walls of the two movable holes 321 are provided with movable grooves 322. Slider 2 33 is slidably arranged in the movable groove 322, and the slider 2 33 is fixedly connected to the outer wall of the center column 34. Under the action of the slider 1 31, the rotating ring 32 can rotate horizontally or forward and backward. At the same time, the center column 34 can rotate left and right under the action of the slider 2 33. With the cooperation of various components, the center column 34 can be rotated in any direction.

[0030] Embodiment 2:

[0031] After the whole is placed, the surveying instrument needs to be installed on the support frame. To ensure that the surveying instrument is installed firmly, please refer to Figure 3On the basis of the first embodiment, the fixing assembly 5 includes a mounting seat 51 installed on the base 4, both sides of the mounting seat 51 are threadedly connected with fixing screws 52, one end of the fixing screw 52 is rotatably connected with a clamping block 53, and the clamping block 53 is slidably set on the mounting seat 51. During installation, the surveying and mapping instrument is placed on the mounting seat 51, the fixing screw 52 is rotated to drive the clamping block 53 to move, and the surveying and mapping instrument can be clamped by using the two clamping blocks 53.

[0032] Through the above embodiments, it can be known that when in use, the support rod 22 is first unfolded, and the support rod 22 can be limited by the block 23, so that the support rod 22 will not continue to move after being unfolded, and the whole body can be kept in a supported state, and then the height of the base 25 is controlled by adjusting the screw 24. When facing a stepped ground or a bumpy ground, the stability of the whole body during use can also be guaranteed. Then the rotatable fixed screw 52 will drive the clamping block 53 to move, and the two clamping blocks 53 can be used to clamp the surveying and mapping instrument. Then, under the action of the movable component 3, the gravity of the counterweight ball 35 is used. When the whole body is placed on the slope, the whole body is in an inclined state, and under the action of the universal moving part, the counterweight ball 35 drives the center column 34 to always be in a vertical state, which can ensure that the surveying and mapping instrument can be in a horizontal state after installation. Finally, the surveying and mapping work can be carried out through the surveying and mapping instrument.
