Summary of the invention

[0003] In view of the deficiencies in the prior art, the present invention provides a surveying instrument for engineering surveying and mapping, which achieves the purpose of solving the above-mentioned problems.

[0004] To achieve the above purpose, the present invention is implemented through the following technical solutions: a surveying instrument for engineering surveying and mapping, comprising a connecting frame, a surveying instrument is arranged on the top of the connecting frame, a triangular support frame is arranged at the bottom of the connecting frame, a telescopic frame is slidably connected to the inner wall of the triangular support frame, and a stabilizing mechanism is arranged at the bottom of the telescopic frame; The stabilizing mechanism comprises: A connecting sleeve, the top of which is fixedly connected to the bottom of the telescopic frame, the connecting sleeve is a circular sleeve structure, a spring is fixedly connected to the top of the inner wall of the connecting sleeve, one end of the spring is fixedly connected to a sliding column, the outer wall of the sliding column is slidably connected to the inner wall of the connecting sleeve, and the connecting sleeve is used to allow the sliding column to slide on its inner wall; The connecting column is a circular disc-shaped structure, a conical block is fixedly connected to the bottom of the connecting column, the conical block is a conical structure, the connecting column is used to connect the conical block, and the conical block is used to be quickly inserted into the soil.

[0005] Preferably, an arc-shaped inclined plate is provided outside the connecting column, the outer wall of the arc-shaped inclined plate is an arc-shaped surface, and the inner wall of the connecting sleeve is slidably connected to the outer wall of the sliding column through a sliding groove, and the sliding groove is used to prevent the sliding column from sliding out of the connecting sleeve.

[0006] Preferably, the outer wall of the connecting column is provided with an anti-breaking mechanism, and the anti-breaking mechanism comprises a magnetic ring A, and the magnetic ring A is a circular hollow ring structure.

[0007] Preferably, the inner wall of the magnetic ring A contacts with a magnetic ring B, the magnetic ring B and the magnetic ring A are magnetic, and the magnetic ring A and the magnetic ring B are attracted to each other.

[0008] Preferably, the inner wall of the magnetic ring B is fixedly connected to the outer wall of the connecting sleeve, the magnetic ring B is a circular hollow ring structure, and magnetic blocks are fixedly connected to both sides of the arc-shaped inclined plate.

[0009] Preferably, the outer wall of the connecting column is provided with four arc-shaped inclined plates, and the four arc-shaped inclined plates are arranged in an equiproportional circular array outside the connecting column with the center of the connecting column as the center of the circle.

[0010] Preferably, a rotating shaft is fixedly connected to the bottom of the arc-shaped inclined plate, a hollow sleeve is rotatably connected to the outer wall of the rotating shaft, and the outer wall of the hollow sleeve is fixedly connected to the outer wall of the connecting column.

[0011] Preferably, the magnetic block has magnetism, and the magnetism of the magnetic block and another adjacent magnetic block on the opposite side is that opposite poles attract each other.

[0012] The present invention provides a surveying instrument for engineering surveying and mapping, which has the following beneficial effects: 1. The present invention provides a stabilizing mechanism. Since the arc-shaped inclined plate is in an inclined state, it will not cause any obstruction when inserted into the soil. After the connecting sleeve is completely inserted into the soil, once the tripod support frame and the telescopic frame are accidentally touched or collided during the surveying process, the telescopic frame will be pulled up. In this case, the arc-shaped inclined plate is in an inverted tooth shape, thereby tightly grasping the soil and causing greater resistance, thereby preventing the telescopic frame from being quickly pulled out when hit, causing the surveying instrument above to fall over and causing surveying accidents, as well as damage to the surveying instrument.

[0013] 2. The present invention provides a stabilizing mechanism to give the telescopic frame a certain space for lifting movement, so as to avoid the problem that the telescopic frame and the triangular support frame are broken due to the arc-shaped inclined plate being stuck with the soil when the telescopic frame is lifted up with great force. The connecting sleeve and the telescopic frame have a certain lifting space, and the elastic force of the spring is used to buffer the lifting force of the collision when lifting. Finally, the sliding column cannot escape from the connecting sleeve and will be stuck on the inner wall of the connecting sleeve. The arc-shaped inclined plate is still used to ensure that the telescopic frame will not escape from the soil, but a certain buffer space will be provided for lifting the telescopic frame to ensure the stability of the telescopic frame and the triangular support frame and prevent them from breaking, thereby further ensuring the stable working state of the surveying instrument and reducing the problem of information loss caused by damage due to tipping.

[0014] 3. The present invention provides a stabilizing mechanism. When the telescopic frame is impacted with great force, the magnetic ring B on the outer wall of the connecting sleeve will quickly separate from the magnetic ring A, and then the connecting sleeve will separate from the connecting column and start to move upward. A slight touch cannot push away the magnetic attraction between the magnetic ring A and the magnetic ring B, thereby failing to push the telescopic frame. This avoids the stability of the surveying instrument under normal working conditions, ensures the safety of the surveying instrument and that the telescopic frame will not break, and at the same time, improves the stability of the surveying instrument under regular operation as much as possible to ensure the accuracy of information data collection.

[0015] 4. The present invention provides an anti-breakage mechanism, so that when the impact force is large, the arc-shaped inclined plate is no longer used to forcibly grasp the soil, so as to release the impact force of the telescopic frame, thereby avoiding the problem of fracture caused by excessive internal stress when the bottom of the telescopic frame is fixed but subjected to a large impact. The telescopic frame is naturally pulled out of the soil by automatically identifying the impact force, and the friction between the telescopic frame and the soil when pulled out is used to further release the force, thereby protecting the surveying instrument while also protecting the telescopic frame and the triangular support frame from fracture, thereby avoiding the situation where the telescopic frame is directly broken when subjected to a collision force that can cause it to break, causing the surveying instrument to fall quickly and be damaged.

DETAILED DESCRIPTION

[0018] Example 1: Please refer to Figure 1-4 The present invention provides a technical solution: a surveying instrument for engineering surveying, comprising a connecting frame 6, a surveying instrument 1 is arranged on the top of the connecting frame 6, a triangular support frame 2 is arranged at the bottom of the connecting frame 6, a telescopic frame 5 is slidably connected to the inner wall of the triangular support frame 2, and a stabilizing mechanism 3 is arranged at the bottom of the telescopic frame 5; The stabilizing mechanism 3 comprises: A connecting sleeve 301, the top of which is fixedly connected to the bottom of the telescopic frame 5, the connecting sleeve 301 is a circular sleeve structure, a spring 302 is fixedly connected to the top of the inner wall of the connecting sleeve 301, one end of the spring 302 is fixedly connected to a sliding column 303, the outer wall of the sliding column 303 is slidably connected to the inner wall of the connecting sleeve 301, and the connecting sleeve 301 is used to allow the sliding column 303 to slide on its inner wall; The connecting column 304 is a circular disc-shaped structure. A conical block 305 is fixedly connected to the bottom of the connecting column 304. The conical block 305 is a conical structure. The connecting column 304 is used to connect the conical block 305. The conical block 305 is used to quickly insert into the soil. When in use, the telescopic frame 5 is pulled out from the triangular support frame 2 and fixed, and then the triangular support frame 2 under the connecting frame 6 is supported and opened, and the bottom end of the telescopic frame 5 is inserted into the soil to complete the support and stability of the triangular support frame 2 and the connecting frame 6, and then the surveying instrument 1 is fixed on the connecting frame 6, and after the surveying instrument 1 is adjusted horizontally, the surveying instrument 1 can be used to start the surveying work; Example 2: Please refer to Figure 1-8On the basis of the first embodiment, the present invention provides a technical solution: an arc-shaped inclined plate 306 is arranged outside the connecting column 304, the outer wall of the arc-shaped inclined plate 306 is an arc-shaped surface, the inner wall of the connecting sleeve 301 is slidably connected with the outer wall of the sliding column 303 through a sliding groove, and the sliding groove is used to prevent the sliding column 303 from sliding out of the connecting sleeve 301; After the telescopic frame 5 is pulled out from the tripod support frame 2 and fixed, when the three telescopic frames 5 under the three tripod support frames 2 are inserted into the soil, the bottom end of the telescopic frame 5 first contacts the soil through the conical block 305, and as the spike shape of the conical block 305 is inserted into the soil, the soil covers the conical block 305, the connecting column 304 to the inclined arc-shaped inclined plate 306 and the connecting sleeve 301, until the entire connecting sleeve 301 is completely inserted into the soil. Since the arc-shaped inclined plate 306 is in an inclined state, the insertion into the soil will not cause any obstacles. After the connecting sleeve 301 is completely inserted into the soil, once the tripod support frame 2 and the telescopic frame 5 are accidentally touched or collided during the surveying and mapping process, the telescopic frame 5 will be pulled up at this time, and the arc-shaped inclined plate 306 will be in an inverted tooth shape, thereby tightly grasping the soil and causing greater resistance, so as to avoid the telescopic frame 5 being pulled out quickly when being hit, causing the surveying and mapping instrument 1 above to fall over and causing surveying and mapping accidents, as well as damage to the surveying and mapping instrument 1. When the telescopic frame 5 is pushed with great force, since the other two telescopic frames 5 remain inserted into the soil stably, the telescopic frame 5 that is collided will begin to be subjected to the upward component force and begin to lift up. Therefore, when the telescopic frame 5 is pushed and pulled up from the soil, since the arc-shaped inclined plate 306 is in the shape of an inverted tooth, when the telescopic frame 5 is lifted up, it will rise together with the connecting sleeve 301, and the connecting column 304 and the conical block 305 are fixed in the soil by the arc-shaped inclined plate 306. When the connecting sleeve 301 is pulled up by the telescopic frame 5, the inner wall of the connecting sleeve 301 will slide on the outer wall of the sliding column 303, and the spring 302 between the sliding column 303 and the connecting sleeve 301 will be pulled to deform, and the sliding column 303 is fixed by the connecting column 304, so as to form a support for the telescopic frame 5 when it is lifted up by the elastic force of the spring 302. Resistance, and give the telescopic frame 5 a certain space for lifting movement, to avoid the telescopic frame 5 and the triangular support frame 2 from breaking due to the arc-shaped inclined plate 306 being stuck with the soil when the telescopic frame 5 is lifted up with great force, using the connecting sleeve 301 and the telescopic frame 5 to have a certain lifting space, and using the elastic force of the spring 302 to buffer the lifting force of the collision when lifting, and finally the sliding column 303 cannot escape from the connecting sleeve 301 and will be stuck on the inner wall of the connecting sleeve 301, and the arc-shaped inclined plate 306 is still used to ensure that the telescopic frame 5 will not fall out of the soil, but a certain buffer space will also be provided for lifting the telescopic frame 5, to ensure the stability of the telescopic frame 5 and the triangular support frame 2 and will not break, and then further ensure the stable working state of the surveying instrument 1, and reduce the problem of information loss caused by damage caused by tipping; When the connecting sleeve 301 is pulled upward by the telescopic frame 5, only when the telescopic frame 5 is hit with a large force, the magnetic ring B402 on the outer wall of the connecting sleeve 301 will quickly separate from the magnetic attraction of the magnetic ring A401, and then the connecting sleeve 301 will separate from the connecting column 304 and start to move upward. A slight touch cannot push away the magnetic attraction between the magnetic ring A401 and the magnetic ring B402, so that the telescopic frame 5 cannot be pushed, thereby avoiding the stability of the surveying instrument 1 under normal working conditions, ensuring the safety of the surveying instrument 1 and the telescopic frame 5 will not break, while also improving the stability of the surveying instrument 1 under normal operation as much as possible to ensure the accuracy of information data collection; Example 3: Please refer to Figure 1-11 On the basis of the first and second embodiments, the present invention provides a technical solution: the outer wall of the connecting column 304 is provided with an anti-breaking mechanism 4, the anti-breaking mechanism 4 includes a magnetic ring A401, and the magnetic ring A401 is a circular hollow ring structure.

[0019] The inner wall of the magnetic ring A401 contacts with the magnetic ring B402. The magnetic ring B402 and the magnetic ring A401 are magnetic, and the magnetic rings A401 and B402 are attracted to each other.

[0020] The inner wall of the magnetic ring B402 is fixedly connected to the outer wall of the connecting sleeve 301 . The magnetic ring B402 is a circular hollow ring structure. The two sides of the arc-shaped inclined plate 306 are fixedly connected with magnetic blocks 403 .

[0021] Four arc-shaped inclined plates 306 are disposed on the outer wall of the connecting column 304 . The four arc-shaped inclined plates 306 are arranged in an equiproportionate annular array outside the connecting column 304 with the center of the connecting column 304 as the center of the circle.

[0022] The bottom of the arc-shaped inclined plate 306 is fixedly connected with a rotating shaft 404 , and the outer wall of the rotating shaft 404 is rotatably connected with a hollow sleeve 405 , and the outer wall of the hollow sleeve 405 is fixedly connected to the outer wall of the connecting column 304 .

[0023] The magnetic block 403 has magnetism, and the magnetism of the magnetic block 403 and another adjacent magnetic block 403 on the opposite side is that opposite poles attract each other; When the force of the collision with the telescopic frame 5 is too great, when the connecting sleeve 301 pulls the spring 302 to deform to the maximum extent, and the sliding column 303 slides from the inner wall of the connecting sleeve 301 to the maximum position and gets stuck, when the upward lifting force of the telescopic frame 5 still cannot be resolved, the pressure between the upper part of the arc inclined plate 306 and the soil will increase instantly, and when the downward pressure on the arc inclined plate 306 by the soil is greater than the preset force of the magnetic attraction between the magnetic blocks 403 on both sides of the arc inclined plate 306 and another magnetic block 403, each arc inclined plate 306 will be disengaged from each other, and the arc inclined plates 306 are no longer magnetically attracted to each other to remain fastened, and as the telescopic frame 5 is lifted, the arc inclined plates 306 are flipped over in the opposite direction, and the arc inclined plates 306 are turned over. The plate 306 drives the rotating shaft 404 to rotate and descend in the inner wall of the hollow sleeve 405, so that when the impact force is large, the arc-shaped inclined plate 306 is no longer forcibly used to grasp the soil, so as to release the impact force on the telescopic frame 5, thereby avoiding the problem of the telescopic frame 5 being fixed at the bottom but being hit by a large force, resulting in excessive internal stress and causing fracture. The telescopic frame 5 is naturally pulled out of the soil by automatically identifying the impact force, and the friction with the soil when pulling out is used to further release the force, thereby protecting the surveying instrument 1 while also protecting the telescopic frame 5 and the triangular support frame 2 from fracture, thereby avoiding the telescopic frame 5 being directly broken when it is subjected to a collision force that can cause it to break, causing the surveying instrument 1 to fall quickly and cause damage.

Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
