Description

Technical Field

[0001] This utility model relates to the field of surveying equipment technology, and in particular to an auxiliary device for topographic mapping. Background Technology

[0002] Before construction begins, a survey of the area to be constructed is necessary to understand its geology and topography. This surveying process utilizes a variety of equipment, such as total stations, theodolites, positioning instruments, and distance measuring instruments. To facilitate the use of this equipment, a support frame is typically used. A circular mounting plate is mounted on top of the support frame. After placing the support frame on the survey ground, the survey equipment is mounted on the plate. The support frame provides good support for the equipment, ensuring the stability of the survey. However, the ground in the survey area is not always level, so the support frame installation... In non-horizontal areas, surveying equipment will also be in a non-horizontal position. Some current supports provide leveling functions, which can adjust the angle of the surveying equipment to ensure that it is in a horizontal state for data collection. However, it is impossible to confirm whether the surveying equipment is tilted or whether the adjustment is level. Generally, surveyors need to use a plumb bob to assist in testing the levelness. When using a plumb bob to test the levelness, it is necessary to measure the levelness at multiple locations. Therefore, the plumb bob needs to be disassembled and reassembled multiple times. During the disassembly and reassembly process, it is easy to touch the support, causing the tilt of the support to change, resulting in repeated measurements and adjustments. Utility Model Content

[0003] In view of this, the present invention proposes an auxiliary device for topographic mapping, which can help detect whether the support and surveying equipment are level, and improve the accuracy of the measurement results through multi-point measurement.

[0020] To better understand the technical content of this utility model, a specific embodiment is provided below, and the utility model will be further described in conjunction with the accompanying drawings.

[0021] See Figures 1 to 3 This utility model provides an auxiliary device for topographic mapping, including a U-shaped frame 1, a connecting line 2, a plumb bob 3, a rotary motor 4, a rotating drum 5, and a position changing mechanism. The opening of the U-shaped frame 1 faces one side. The rotary motor 4 is located on the bottom surface of the U-shaped frame 1, and its output shaft is connected to one end of the rotating drum 5. The connecting line 2 is wound on the rotating drum 5, and the plumb bob 3 is connected to the bottom end of the connecting line 2. The position changing mechanism includes a mounting frame 6, a moving wheel 7, a motor 8, and a clamping spring 9. The mounting frame 6 is located on the inner top and inner bottom surfaces of the U-shaped frame 1. The moving wheel 7 is located inside the mounting frame 6. The motor 8 is located on the side wall of the mounting frame 6, and its output shaft passes through the mounting frame 6 and is connected to the moving wheel 7. The clamping spring 9 connects the top surface of the upper mounting frame 6 with the inner top surface of the U-shaped frame 1 and the bottom surface of the lower mounting frame 6 with the inner bottom surface of the U-shaped frame 1. A clamping position 10 is formed between the moving wheels 7 for a circular mounting plate above the support to extend into.

[0022] This utility model discloses an auxiliary device for topographic surveying, used to assist in adjusting the level of a support frame and the surveying equipment on the circular mounting plate of the support frame. After the surveying equipment is installed on the circular mounting plate, the U-shaped frame 1 is moved to one side of the circular mounting plate, and the circular mounting plate is inserted into the clamping position 10 in the U-shaped frame 1. The circular mounting plate is clamped and fixed by the upper and lower moving wheels 7, realizing the connection between the U-shaped frame 1 and the circular mounting plate. Then, the rotating motor 4 can drive the rotating drum 5 to rotate. During the rotation of the rotating drum 5, the connecting line 2 can be released, so that the plumb line 3 is lowered to one side of the support frame. Through the gravity of the plumb line 3, it can be determined whether the support frame and the surveying equipment are in a level state, so as to facilitate adjustment.

[0023] The circular mounting plate is connected to the upper and lower parts of the rotating wheel 7. The rotating wheel 7 is located in the mounting frame 6, and the mounting frame 6 is connected to the U-shaped frame 1 through the clamping spring 9. Thus, the U-shaped frame 1 can be stably placed on one side of the circular mounting plate. After the motor 8 is started, the motor 8 can drive the rotating wheel 7 to rotate, which can drive the U-shaped frame 1 to move along the circular mounting plate, so as to adjust the plumb bob 3 to different positions for measurement and ensure the accuracy of the horizontal auxiliary measurement results.

[0024] Preferably, it also includes a metal plate 11 and an electromagnet 12. The metal plate 11 is disposed opposite to each other on both sides of the plumb bob 3, and the electromagnet 12 is disposed on the bottom surface of the U-shaped frame 1 and located above the metal plate 11.

[0025] After the plumb bob 3 is lowered to the designated position and during the movement of the entire U-shaped frame 1, the electromagnet 12 can be energized to magnetically attract the metal plate 11, reducing the swaying of the plumb bob 3, quickly stopping the plumb bob 3, and improving the efficiency of tilt judgment of the support and surveying equipment.

[0026] Preferably, the position changing mechanism further includes a sleeve 13 and a moving rod 14. The sleeve 13 is disposed on the inner top surface and inner bottom surface of the U-shaped frame 1. The clamping spring 9 is located in the sleeve 13. The moving rod 14 is disposed on the top surface of the upper mounting frame 6 and the bottom surface of the lower mounting frame 6, and extends into the sleeve 13 to connect with the clamping spring 9.

[0027] The size of the clamping position 10 can be adjusted. When the mounting bracket 6 is moved in the opposite direction, the moving rod 14 will move into the sleeve 13 and compress the clamping spring 9. When the circular mounting plate is in the clamping position 10, the circular mounting plate can be clamped and fixed under the action of the clamping spring 9, and the moving wheel 7 will move along the circular mounting plate by the drive of the motor 8.

[0028] Preferably, it also includes a bracket 15, which is disposed on the bottom surface of the U-shaped frame 1, and the end of the rotating drum 5 away from the rotating motor 4 passes through the bracket 15.

[0029] When the rotary motor 4 drives the rotating drum 5 to rotate, its end can rotate under the support of the bracket 15.

[0030] Preferably, the position changing mechanism further includes a guide wheel 16, which is disposed on the inner side wall of the U-shaped frame 1 and is used to contact the side wall of the circular mounting plate above the bracket.

[0031] To facilitate the movement of the U-shaped frame 1 along the circular mounting plate, guide wheels 16 are installed inside it. The guide wheels 16 can move along the outer wall of the circular mounting plate, allowing the U-shaped frame 1 to turn smoothly.

[0032] Preferably, the position changing mechanism further includes an adjusting plate 17 and a screw 18. The adjusting plate 17 is slidably disposed within the U-shaped frame 1. The screw 18 passes through the side wall of the U-shaped frame 1 and is screwed to the side wall of the U-shaped frame 1. The end of the screw 18 is rotatably connected to the side wall of the adjusting plate 17. The guide wheel 16 is disposed on the side wall of the adjusting plate 17 away from the screw 18. The position changing mechanism further includes a bearing 19, which is disposed on the side wall of the adjusting plate 17. The end of the screw 18 is connected to the bearing 19.

[0033] To accommodate different circular mounting plates, the position of the guide wheel 16 is set to be adjustable. When the screw 18 is rotated, since the screw 18 is screwed to the U-shaped frame 1, it can move horizontally while rotating. The end of the screw 18 is connected to the adjusting plate 17 through the bearing 19. Therefore, the screw 18 will not drive the adjusting plate 17 to rotate, but will only drive the adjusting plate 17 to move horizontally, thereby realizing the position adjustment of the guide wheel 16.

[0034] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
