Description

Technical Field

[0001] The present invention relates to the technical field of total stations, and specifically to a total station for pier construction surveying. Background Art

[0002] In engineering construction, especially in large-scale construction projects such as bridges, roads, and high-rise buildings, precise measurement is a crucial link. It not only relates to the safety and stability of the project but also directly affects the construction efficiency and quality. Therefore, in order to facilitate the measurement and calculation of engineering construction, corresponding total stations are usually used.

[0003] For example, the publication number is: CN220153578U, the patent name is: A Total Station, and the publication date is: December 8, 2023. It includes a connecting bracket, on the end face of which a total station is connected. A telescopic sunshade structure is connected to the total station, and a controller is arranged on the total station. The telescopic sunshade structure includes a fixed bracket, which is connected to the handle of the total station. A driving motor is connected to the end face of the fixed bracket through a connecting plate. Among the above existing technologies, the following technical problems exist: When the existing total station is in use, its instrument is supported by the support frame at the bottom. However, when the total station is used for outdoor surveying, it is inevitable to encounter strong wind weather. When the external wind force is large, in order to ensure the stability of the total station, it is only possible to insert the tip of the bottom of the support frame into the soil to achieve the stability of the total station, resulting in poor overall stability. At the same time, when the total station is carried, the tip of the bottom of the support frame is exposed outward, which is also likely to cause harm to personnel.

[0004] Therefore, we propose a total station for pier construction surveying to solve the problems raised above. Summary of the Invention

[0005] The purpose of the present invention is to provide a total station for pier construction surveying to solve the problem that when the existing total station on the current market is in use, its instrument is supported by the support frame at the bottom. However, when the total station is used for outdoor surveying, it is inevitable to encounter strong wind weather. When the external wind force is large, in order to ensure the stability of the total station, it is only possible to insert the tip of the bottom of the support frame into the soil to achieve the stability of the total station, resulting in poor overall stability. At the same time, when the total station is carried, the tip of the bottom of the support frame is exposed outward, which is also likely to cause harm to personnel.

[0006] To achieve the above object, the present invention provides the following technical solution: A total station for pier construction surveying, including a support platform and a total station body installed on the upper end of the support platform. A central column is fixed to the lower end of the support platform, and an adjusting collar is sleeved on the central column. A locking screw is connected to the side of the adjusting collar, and the end of the locking screw is screwed into the positioning hole on the side of the central column. The adjusting collar is connected to the support column through a power link, and the upper end of the support column is rotatably connected below the support platform. A counterweight is inserted into the middle of the central column, and an accommodating cavity is arranged inside the lower end of the counterweight. A moving plate is connected to the accommodating cavity inside the counterweight through an auxiliary spring, and the middle part of the lower end of the moving plate is set as a spiked end. The upper end of the counterweight is connected to the inside of the central column through a return spring.

[0007] Preferably, the adjusting collar and the central column are in sliding connection, and both the adjusting collar and the support column are hinged to the power link.

[0008] By adopting the above technical solution, when the adjusting collar moves on the central column, the movement of the adjusting collar can be used to make the hinged power link push the support column to rotate.

[0009] Preferably, the accommodating cavity inside the counterweight is set as an open structure, and the upper end of the counterweight forms a seamless sliding connection structure with the central column through a circumferentially wrapped sealing ring.

[0010] By adopting the above technical solution, through the open structure of the accommodating cavity, it is convenient to add counterweight raw materials into the counterweight, thereby increasing the self-weight of the counterweight and making the counterweight move downward to lower the overall center of gravity of the instrument.

[0011] Preferably, the moving plate is circumferentially wrapped with a sealing ring to improve the sealing performance when the moving plate moves in the accommodating cavity inside the counterweight, and a channel for the spiked end in the middle of the lower end of the moving plate to extend out is opened on the counterweight, and the inner diameter of the channel is larger than the diameter of the spiked end.

[0012] By adopting the above technical solution, after the counterweight raw materials are added into the counterweight, the weight of the raw materials can make the moving plate move downward, so that the spiked end on the moving plate extends out of the channel on the counterweight.

[0013] Preferably, a gas storage cavity is formed between the section of the counterweight extending into the central column and the inside of the central column, and the gas storage cavity is connected to a stability control component through an air delivery hose, and the stability control component is installed in a guiding groove opened on the support column.

[0014] By adopting the above technical solution, the guiding groove opened on the support column can provide a moving space for the stability control component.

[0015] Preferably, the stable regulation component includes an elastic rubber block connected to the gas transmission hose, and the elastic rubber block is fixed between the inside of the connection block and the end of the anchoring pin. The anchoring pin is installed through the connection block, and the anchoring pin is inserted into the protection hole opened in the middle of the movable base. The movable base is connected to the side of the connection block through a built-in spring, and a moving shaft is fixed on the connection block. The moving shaft is inserted into the sliding groove opened on the support column, and a compression nut is connected to the moving shaft.

[0016] By adopting the above technical solution, after the counterweight moves downward to the lower part of the central column, the air flow inside the air storage chamber can enter the inside of the elastic rubber block through the gas transmission hose.

[0017] Preferably, the anchoring pin and the connection block are in sliding connection, and the tip of the anchoring pin is located in the protection hole inside the movable base in the initial state.

[0018] By adopting the above technical solution, the tip of the anchoring pin can be stored and protected through the setting of the protection hole.

[0019] Preferably, the outer walls of the movable base and the connection block are both in mutual contact with the inner wall of the guide groove, and both the movable base and the connection block can slide in the guide groove, and the movable base and the connection block form an elastic telescopic structure through a built-in spring.

[0020] By adopting the above technical solution, the outer wall of the movable base, the outer wall of the connection block and the inner wall of the guide groove are in mutual contact, so as to ensure the stability of the movable base and the connection block when moving in the guide groove.

[0021] Preferably, a section of the surface of the moving shaft extending out of the connection block is provided with threads, the moving shaft and the compression nut are in threaded connection, and the side of the compression nut facing the support column is set as a rough surface.

[0022] By adopting the above technical solution, by rotating the compression nut on the moving shaft, the compression nut can be pressed against the side of the support column to fix the position of the moved connection block.

[0023] Compared with the prior art, the beneficial effects of the present invention are: the total station for pier construction surveying can improve the stability of the surveying instrument by reducing the center of gravity of the total station when encountering strong wind weather, and at the same time can protect the tip inserted into the soil during carrying to prevent the tip from stabbing people; 1. An adjusting collar is provided. By moving the adjusting collar on the central column, the supporting column can be pushed to rotate by means of the articulated power link, so that the supporting column can be rotated and opened to support the total station body. The end of the locking screw is rotated and screwed into the positioning hole on the side of the central column, so as to fix the position of the moved adjusting collar; 2. A counterweight is provided. By adding counterweight materials, such as water or sand, into the accommodating cavity inside the counterweight, the counterweight can move downward to the lower part of the central column after adding the counterweight materials. After the counterweight moves downward, it can contact the ground, thereby reducing the overall center of gravity of the instrument. At the same time, after adding the counterweight materials, the moving plate can move downward. After the moving plate moves downward, the spiked end can extend out of the counterweight. At this time, after the counterweight contacts the ground, the spiked end can be inserted into the soil to further improve the stability of the instrument during use. In the initial state, the spiked end is located inside the counterweight and will not cause injury to personnel during carrying; 3. A movable base is provided. After the supporting column is unfolded, the connecting block and the movable base are moved downward on the supporting column, so that the lower end of the movable base extends out of the supporting column. At this time, on each supporting column, the movable base moves to different degrees on the connecting block, so as to ensure the stability of the instrument when placed on uneven ground; 4. An air delivery hose is provided. After the counterweight moves downward, it can squeeze the air flow in the air storage cavity, so that the air flow can enter the inside of the elastic rubber block through the air delivery hose. Through the inflation and expansion of the elastic rubber block, the anchoring pin can move, and the tip of the anchoring pin can extend out of the protection hole on the movable base and be inserted into the soil, so as to further improve the stability of the instrument in strong wind weather; 5. A connecting block is provided. In the initial state, the connecting block and the movable base are located in the guiding groove inside the supporting column, which can occupy a smaller area during carrying compared to directly extending the movable base out of the supporting column in the initial state. At the same time, whether it is the moving direction of the connecting block and the movable base or the moving direction of the anchoring pin during adjustment is downward, so the center of gravity of the instrument can be effectively reduced.

Specific embodiments

[0026] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0027] Embodiment 1: Please refer to Figures 1-9, when the existing total station is in use, it is supported by the support frame at the bottom. However, when the total station is used for outdoor surveying and mapping, it is inevitable to encounter strong wind weather. When the external wind force is large, in order to ensure the stability of the total station, it can only be stabilized by inserting the tip of the bottom of the support frame into the soil, resulting in poor overall stability. At the same time, when the total station is carried, the tip of the bottom of the support frame is exposed outward, which is also easy to cause harm to personnel. To solve this technical problem, the following technical content is disclosed in this embodiment. A total station for pier construction surveying includes a support platform 1 and a total station body 2 installed on the upper end of the support platform 1. A central column 3 is fixed to the lower end of the support platform 1, and an adjustment collar 4 is sleeved on the central column 3. A locking screw 5 is connected to the side of the adjustment collar 4, and the end of the locking screw 5 is screwed into the positioning hole 6 on the side of the central column 3. The adjustment collar 4 is connected to the support column 8 through a power link 7, and the upper end of the support column 8 is rotatably connected below the support platform 1. A counterweight 9 is inserted into the middle of the central column 3, and a receiving cavity 10 is arranged inside the lower end of the counterweight 9. A moving plate 11 is connected to the receiving cavity 10 inside the counterweight 9 through an auxiliary spring 12, and the middle part of the lower end of the moving plate 11 is set as a spiked end. The upper end of the counterweight 9 is connected to the inside of the central column 3 through a return spring 13. The adjustment collar 4 and the central column 3 are in sliding connection, and both the adjustment collar 4 and the support column 8 are hinged to the power link 7. The receiving cavity 10 inside the counterweight 9 is set as an open structure, and the upper end of the counterweight 9 forms a seamless sliding connection structure with the central column 3 through a circumferentially wrapped sealing ring. The moving plate 11 is circumferentially wrapped with a sealing ring to improve the sealing performance when the moving plate 11 moves in the receiving cavity 10 inside the counterweight 9, and a channel for the spiked end in the middle of the lower end of the moving plate 11 to extend out is opened on the counterweight 9, and the inner diameter of the channel is larger than the diameter of the spiked end.

[0028] When it is necessary to use the total station body 2 for measurement, after moving the total station body 2 to a suitable position, push the adjusting collar 4 on the central column 3. After the adjusting collar 4 moves, it can use the articulated power link 7 to push the support column 8 to rotate outward around the upper rotating shaft, thereby supporting the total station body 2 through the unfolded support column 8. Then rotate the locking screw 5 on the adjusting collar 4. After the locking screw 5 rotates, its end can be screwed into the positioning hole 6 on the side of the central column 3 to fix the moved adjusting collar 4. When encountering strong wind weather, add weight materials such as water or sand into the accommodating cavity 10 inside the counterweight 9. At this time, after the weight materials are added, the moving plate 11 can be pushed downward under the gravity pressure. After the moving plate 11 moves downward, the pointed end at the lower end can extend out of the channel of the counterweight 9. As the weight of the counterweight 9 increases, it can move downward below the central column 3. After the counterweight 9 moves, it can not only lower the center of gravity of the instrument, but also make the pointed end extended by the moving plate 11 inside the counterweight 9 insert into the soil, so as to ensure the stability of the total station body 2 in strong wind weather. At the same time, the pointed end on the moving plate 11 is located inside the counterweight 9 in the initial state. Therefore, when carrying the total station body 2, it will not cause injury to personnel due to the exposure of the pointed end.

[0029] Embodiment 2: The technical content disclosed in this embodiment is a further improvement based on the above Embodiment 1. The following technical content is disclosed in this embodiment. A section of the counterweight member 9 extending into the inner part of the central column 3 and the inner part of the central column 3 enclose an air storage cavity 14, and the air storage cavity 14 is interconnected with the stability control component 15 through an air delivery hose 16. The stability control component 15 is installed in a guiding groove 17 opened on the support column 8. The stability control component 15 includes an elastic rubber block 151 interconnected with the air delivery hose 16, and the elastic rubber block 151 is fixed between the inside of the connection block 152 and the end of the anchoring pin 153. The anchoring pin 153 is installed through the connection block 152, and the anchoring pin 153 is inserted into a protection hole 155 opened in the middle of the movable base 154. The movable base 154 is interconnected with the side of the connection block 152 through a built-in spring 156, and a moving shaft 157 is fixed on the connection block 152. The moving shaft 157 is inserted into a sliding groove opened on the support column 8, and a compression nut 158 is connected to the moving shaft 157. The anchoring pin 153 and the connection block 152 are in a sliding connection, and the tip of the anchoring pin 153 is located in the protection hole 155 inside the movable base 154 in the initial state. The outer walls of the movable base 154 and the connection block 152 are both in mutual contact with the inner wall of the guiding groove 17, and both the movable base 154 and the connection block 152 can slide in the guiding groove 17. Moreover, the movable base 154 and the connection block 152 form an elastic telescopic structure through the built-in spring 156. A section of the surface of the moving shaft 157 extending out of the connection block 152 is provided with threads, and the moving shaft 157 and the compression nut 158 are in a threaded connection. And the side of the compression nut 158 facing the support column 8 is set as a rough surface.

[0030] When placing the total station body 2, push the connecting block 152 and the movable base 154 along the lower part of the guiding groove 17 on the support column 8, so that the lower end of the movable base 154 extends out of the support column 8. Then rotate the compression nut 158 on the moving shaft 157 of the connecting block 152 to make the compression nut 158 tightly press against the side of the support column 8, thereby fixing the position of the connecting block 152. Since the lower end of the movable base 154 extends out of the support column 8, when using it on a slightly uneven road surface, the movable bases 154 on different support columns 8 move to different degrees on the connecting block 152, so that the total station body 2 can be placed stably. And the connecting block 152 and the movable base 154 move and adjust along the lower part of the support column 8, so that the overall center of gravity of the instrument can also be reduced. In windy weather, after the counterweight 9 moves along the lower part of the central column 3, the counterweight 9 can squeeze the air flow inside the air storage cavity 14 through the air delivery hose 16 into the inside of the elastic rubber block 151. After the elastic rubber block 151 is inflated, it can push the anchoring pin 153, so that the tip of the anchoring pin 153 can extend out of the protection hole 155 in the middle of the movable base 154 and insert into the soil, so as to further improve the stability of the instrument in windy weather. And the moving direction of the anchoring pin 153 is also downward, so it can also play a role in partially reducing the center of gravity. And the connecting block 152 and the movable base 154 are located inside the guiding groove 17 in the initial state. When carrying, compared with directly setting the movable base 154 at the position extending out of the support column 8 in the initial state, it can occupy a smaller area.

[0031] The content not described in detail in this specification belongs to the prior art well-known to those skilled in the art.

[0032] Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
