Description

Technical Field

[0001] This utility model relates to the field of surveying instrument positioning technology, specifically a surveying instrument positioning device for surveying engineering. Background Technology

[0002] Surveying engineering refers to engineering activities involving the measurement, positioning, data acquisition, processing, and analysis of the ground or other objects using various specialized instruments and techniques. Surveying engineering typically involves surveying of topography, landforms, buildings, roads, bridges, mines, and other projects, providing data support for engineering design, construction, management, and scientific research. The results of surveying engineering are usually presented in the form of drawings, models, digital maps, and Geographic Information System (GIS) data.

[0003] For example, a surveying instrument positioning device for surveying engineering, disclosed in CN222925270U, ​​includes a tripod body. A vertical rod is fixed to the bottom surface of the tripod body. Multiple first connecting rods are rotatably connected to the lower outer side of the vertical rod. A second connecting rod is rotatably connected to the end of each first connecting rod away from the vertical rod. One end of the second connecting rod is rotatably connected to the outer side of the tripod body. A third connecting rod is also rotatably connected to the end of each first connecting rod away from the vertical rod. A connecting rod is rotatably connected to the lower end of the third connecting rod. A support is slidably connected to the outer side of the connecting rod. A fourth connecting rod is rotatably connected to the lower end of the connecting rod. When the tripod body is unfolded, the first support plate automatically rotates to a horizontal position, forming a horizontal contact with the ground. By increasing the contact area, the stability of the tripod body is improved.

[0004] The aforementioned patent proposes that the first support plate automatically turns to a horizontal state, thereby increasing the stability of the tripod body by forming a horizontal contact with the ground and increasing the contact area. However, in actual use, since there are no fixed components, the measuring instrument will be rotated by external forces during the measurement process, resulting in deviations in the measured angle, distance, or direction, thus affecting the accuracy of the measurement data and making it inconvenient to use.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example 1: Please refer to Figures 1-4 A positioning device for a surveying instrument used in surveying engineering includes a positioning structure 1. The positioning structure 1 includes a tripod 11 and a splitting component 12 installed at the top of the tripod 11. An installation platform 14 is installed at the middle of the top of the splitting component 12.

[0024] The mounting platform 14 includes a platform plate 141 and a rotating shaft 142 mounted on the bottom of the platform plate 141. A gear 143 is mounted on the outer surface of the rotating shaft 142.

[0025] The splitting component 12 includes a side fixing plate A121 and a side fixing plate B122 installed on one side of the side fixing plate A121. The inner wall of the middle section formed by the side fixing plate A121 and the side fixing plate B122 is provided with an inner rotating ring groove 127. The side fixing plate A121 is threadedly connected to a fixing component 13.

[0026] The top of the platform plate 141 is provided with a triangular groove 148, and a rubber strip 149 is installed on the inner wall of the triangular groove 148. The triangular groove 148 is adapted to the bottom of the surveying instrument.

[0027] The fixing component 13 includes a hand handle 133 threadedly connected to one side of the inner side of the side fixing plate A121. The outer surface of the side fixing plate A121 has an inner groove 128 on the inner wall of the inner rotating groove 127. A movable strip 131 is movably installed at one end of the hand handle 133. A triangular strip 132 is installed at one end of the movable strip 131. The movable strip 131 is adapted to the inner groove 128.

[0028] In this embodiment: the surveying instrument is placed on the top of the mounting platform 14, with its bottom end inserted into the triangular groove 148. Screws are used to fix the surveying instrument to the platform plate 141. When adjusting the surveying direction, the handheld lever 133 can be held and rotated, causing the moving bar 131 to move outwards along the inner groove 128. The triangular bar 132 moves out from between the teeth of the gear 143 and then into the inner groove 128, removing the restriction on the mounting platform 14. At this time, the handheld surveying instrument is rotated, and the screws... The connection allows the platform plate 141 and the rotating shaft 142 to rotate together when the surveyor rotates. The gear 143, which is installed on the outer surface of the rotating shaft 142, rotates inside the inner rotating ring groove 127. After the surveyor's surveying direction is adjusted, the handheld lever 133 is held and rotated in the opposite direction, causing the moving bar 131 to carry the triangular bar 132 to move towards the center position of the mounting platform 14. The triangular bar 132 is inserted into the tooth groove of the gear 143, which restricts the rotating mounting platform 14 and prevents the surveyor from being rotated by external forces during the measurement process.

[0029] Example 2: This example is an improvement upon Example 1. For details, please refer to [link / reference]. Figures 2-4 An external strip 144 is installed on the outer surface of the rotating shaft 142 and at the upper end of the gear 143. A rotating groove 145 is opened on the outer surface of the external strip 144. A positioning shaft 146 is vertically installed inside the rotating groove 145. A ball bearing 147 is movably installed through the outer surface of the positioning shaft 146. The ball bearing 147 facilitates the rotation of the mounting platform 14 inside the side fixing plate A121 and the side fixing plate B122.

[0030] A threaded hole 123 is provided on one side of the side fixing plate A121, and a bolt 124 is threadedly connected to the inside of one side of the side fixing plate B122. The bolt 124 is threaded into the inside of the threaded hole 123 to fix the side fixing plate A121 and the side fixing plate B122.

[0031] A positioning hole 125 is provided on the outer surface of the side plate A121 away from the threaded hole 123. A positioning rod 126 is installed on the outer surface of the side plate B122 away from the bolt 124. The positioning rod 126 is inserted into the positioning hole 125 to position the installation between the side plate B122 and the side plate A121.

[0032] In this embodiment: During the rotation of the mounting platform 14, the outer surface of the ball bearing 147, which is movably installed inside the rotating groove 145, contacts the inner wall of the inner rotating ring groove 127. The ball bearing 147 facilitates the rotation of the rotating shaft 142 at the middle of the moving bar 131 and the triangular bar 132, which facilitates the rotation of the surveying instrument. After a period of use, the bolt 124 can be unscrewed, and the threaded end of the bolt 124 is turned out from the inside of the threaded hole 123, allowing the side fixing plate B122 to be pulled out. The positioning rod 126 is moved out from the inside of the positioning hole 125, which facilitates the separation between the side fixing plate A121 and the side fixing plate B122, making it easier for the operator to remove the mounting platform 14 for maintenance. When installing the surveying instrument, as the screw rotates, the bottom of the surveying instrument squeezes the rubber strip 149, which dampens the surveying instrument and prevents vibration from affecting the accuracy of the surveying instrument.
