Description

Technical Field

[0001] The present invention relates to the technical field of geological surveying and mapping equipment, in particular to a three-dimensional urban geological surveying and mapping equipment. Background Art

[0002] Geological engineering surveying is the most important and basic survey method in engineering geological investigation, and it is also the most advanced survey work. It uses geological and geological engineering theories to observe and describe various geological phenomena related to engineering construction in detail, so as to find out the spatial distribution of engineering geological conditions in the proposed construction area and the internal relationship between various elements, and reflect them truthfully on a topographic design map of a certain scale according to the accuracy requirements, and compile them into engineering geological maps in conjunction with the data obtained from geological exploration, experiments, etc.

[0003] When using surveying and mapping equipment, it is often necessary to maintain stability to ensure the accuracy of the measurement. However, when the surveying and mapping equipment is used in areas with a lot of vehicle traffic in the city, the vibrations generated by the vehicles may be transmitted to the tripod supporting the surveying and mapping equipment, causing the tripod to vibrate slightly, causing the surveying and mapping equipment to vibrate, affecting the stability of the measurement. Summary of the Invention

[0004] In order to solve the above technical problems, the present invention provides a three-dimensional urban geological surveying and mapping device, comprising a placement table, wherein three supporting legs are rotatably connected to the inner wall of the placement table;

[0005] A surveying and mapping mechanism, wherein a support assembly is fixedly installed on the top of the surveying and mapping mechanism, and a mounting assembly is rotatably provided on the inner wall of the surveying and mapping mechanism, and the support assembly is used to survey and map a three-dimensional geological map of the city;

[0006] A buffer mechanism is installed at the bottom of the surveying and mapping mechanism to reduce vibrations experienced by the supporting assembly; and

[0007] The horizontal mechanism is located at the inner wall of the buffer mechanism and is used to ensure the level of the surveying and mapping mechanism;

[0008] The bottom of each of the three support legs is provided with a pneumatic sleeve. The three pneumatic sleeves contain the same parts. A fixing ring is fixedly connected to the inner wall of the pneumatic sleeve, and a piston rod is slidably connected to the inner wall of the pneumatic sleeve.

[0009] Among them, the three-dimensional geological map of the city is mapped by using a surveying and mapping agency. During the surveying and mapping, the vibration of the surveying and mapping agency is reduced by a buffering mechanism, thereby reducing the vibration of the measuring instrument. This effectively prevents the measuring instrument from vibrating frequently when mapping in areas with a large number of vehicles, thereby affecting the accuracy of the surveying and mapping. Finally, the leveling mechanism is used to ensure that the surveying and mapping agency is level during the surveying and mapping.

[0010] Preferably, the surveying and mapping organization includes:

[0011] A support assembly, the bottom of which is fixedly arranged on the top of the placement table and is used to support the measuring instrument;

[0012] An installation component, the outer wall of the installation component is rotatably arranged on the inner wall of the placement table for installing a measuring instrument;

[0013] The support assembly is opened to make the three support legs stably contact the ground, and the support legs are fixed by the mounting assembly so that the measuring instrument is stably mounted on the support assembly.

[0014] Preferably, the buffer mechanism comprises:

[0015] An extrusion assembly is slidably arranged on the inner wall of the air pressure sleeve and is used for extruding gas;

[0016] A reset assembly is slidably arranged on the inner wall of the air pressure sleeve and is used to reset the extrusion assembly;

[0017] Among them, when the support assembly is opened, the extrusion assembly will be squeezed, squeezing the gas in the air pressure sleeve, causing the gas pressure to increase. The high-pressure gas will absorb the vibration of the support assembly, effectively preventing the measuring instrument from vibrating frequently when surveying in areas with a large number of vehicles, thereby affecting the accuracy of surveying.

[0018] Preferably, the horizontal mechanism comprises:

[0019] A pushing component is slidably arranged on the inner wall of the air pressure sleeve and is used to limit the displacement distance of the extrusion component;

[0020] A placement assembly is slidably disposed on the outer wall of the air pressure sleeve for providing additional support at the bottom of the support leg;

[0021] Among them, when the extrusion component rises, it will drive the pushing component to rise, causing the placement component to drop close to the ground until the placement component contacts the ground, providing additional support, effectively preventing the piston rod from displacing a large amplitude, causing the support legs to tilt slightly, affecting the level of the measuring instrument.

[0022] Preferably, the support assembly includes a surveyor fixedly connected to the top of the placement table;

[0023] The mounting assembly includes three threaded knobs that are threadedly connected to the inner wall of the placement table, and the bottoms of the three support legs are fixedly connected to spherical rods;

[0024] Among them, the three support legs are rotated to open the support legs. After the support legs are opened, the threaded knob is rotated to move toward the support legs, squeezing the support legs, fixing the support legs, making the squeezing assembly contact with the ground, and supporting the surveying instrument.

[0025] Preferably, the extrusion assembly includes a counterweight block fixedly connected to the outer wall of the air pressure sleeve, and the inner walls of the three air pressure sleeves are rotatably connected to the outer walls of the three spherical rods.

[0026] Preferably, the extrusion assembly further comprises an extrusion ring slidably connected to the inner wall of the air pressure sleeve, and the outer wall of the piston rod is slidably connected to the inner wall of the fixed ring;

[0027] Among them, the pneumatic sleeve is rotated to make it perpendicular to the ground. Finally, the pneumatic sleeve is lowered to make the piston rod contact the ground. The pneumatic sleeve is affected by the weight of the surveying instrument, support legs and counterweight, and will drop. Since the piston rod is in a stationary state, the pneumatic sleeve drops, and the piston rod appears to rise relative to the pneumatic sleeve, allowing the piston rod to squeeze the gas in the pneumatic sleeve, causing the gas pressure to increase. As the piston rod continues to move, the gas pressure at the top of the piston rod will increase until the piston rod stops moving, so that the support legs remain stable and the surveying instrument is stable. The three-dimensional geological map of the city is then mapped by the surveying instrument. Among them, when the surveying instrument is surveying in an area with many vehicles, the ground vibration generated by the driving of the vehicles will be transmitted to the piston rod, causing the piston rod to vibrate slightly. When the piston rod moves slightly and moves upward, the kinetic energy is absorbed by the compressibility of the high-pressure gas at the top of the piston rod, slowing down the vibration, thereby reducing the vibration of the surveying instrument, effectively preventing the surveying instrument from vibrating frequently when surveying in areas with many vehicles, thereby affecting the accuracy of the survey.

[0028] Preferably, the reset assembly includes a sliding groove formed on the inner wall of the piston rod, an air hole is formed on the inner wall of the piston rod, and a spring reset rod is slidably connected to the inner wall of the sliding groove;

[0029] A connecting hole is provided on the inner wall of the piston rod, and the top of the spring return rod is fixedly connected to the bottom of the extrusion ring;

[0030] Among them, when the extrusion ring stops moving, the piston rod continues to rise and squeezes the spring return rod. The high-pressure gas on the top of the piston rod will enter the sliding groove through the air hole and move to the top of the spring return rod. The spring return rod will squeeze the gas in the sliding groove and enter the bottom of the piston rod through the connecting hole. When the piston rod is subjected to a large vibration force and the force disappears, the rebound force of the spring return rod will be released, allowing the piston rod to return to its position. The high-pressure gas at the top of the spring return rod will slow down the return speed of the spring return rod, effectively preventing the spring return rod from releasing its rebound force too quickly, causing the piston rod to quickly contact the ground, causing the piston rod to have an impact, which may cause secondary vibration and affect the stability of the surveying instrument during surveying.

[0031] Preferably, the pushing assembly includes a connecting frame slidably connected to the inner wall of the air pressure sleeve, and the bottom of the connecting frame is fixedly connected to the top of the extrusion ring;

[0032] A fixing frame is fixedly connected to the outer wall of the air pressure sleeve, and a rotating frame is rotatably connected to the outer wall of the fixing frame;

[0033] Among them, in order to solve the problem that when large vehicles appear around the surveying instrument, the vibration amplitude of the piston rod will increase, resulting in a larger movement amplitude of the piston rod, affecting the level of the surveying instrument, when the piston rod rises, it will drive the spring return rod and the extrusion ring to rise, and then let the connecting frame rise, pushing the placement component down.

[0034] Preferably, the placement assembly includes a connecting ring arranged on the outer wall of the air pressure sleeve, the bottom of the connecting ring is fixedly connected to six support rods, the top of the connecting ring is fixedly connected to a sliding rod, and the outer wall of the connecting ring is fixedly connected to a sliding sleeve;

[0035] The inner wall of the sliding sleeve is slidably connected to the outer wall of the sliding rod, the top of the sliding rod is slidably connected to the inner wall of the rotating frame, and the bottom of the connecting frame is slidably connected to the inner wall of the rotating frame;

[0036] Among them, the connecting frame will pull the rotating frame to rotate, causing the rotating frame to tilt, so that the side of the rotating frame close to the connecting frame rises and the other side falls. The falling side will push the sliding rod down, so that the sliding rod pushes the connecting ring and the support rod down. As the connecting frame continues to rise, the connecting frame will be blocked by the air pressure sleeve, causing the connecting frame to stop moving and the extrusion ring to stop moving. At this time, the piston rod continues to rise, which will squeeze the spring return rod, so that the spring return rod accumulates rebound force. As the piston rod continues to move, the support rod will contact the ground for additional support. When the piston rod is subjected to a large vibration amplitude, the piston rod and the support rod rise at the same time. When the support rod rises, the extrusion ring will fall, causing the piston rod and the extrusion ring to squeeze the spring return rod at the same time, and the spring return rod is squeezed in both directions, applying a reaction force to the piston rod, reducing the movement amplitude of the piston rod, and effectively preventing the piston rod from displacing a large amplitude, causing the support leg to tilt slightly, affecting the level of the surveying instrument.

[0037] The present invention has the following beneficial effects:

[0038] (1) When the present invention is used, the operator moves the device to the position to be surveyed. After moving to the position, the operator supports the surveyor through the support assembly, then rotates the air pressure sleeve so that the air pressure sleeve is perpendicular to the ground. Finally, the extrusion assembly is lowered to make the piston rod contact the ground, and the piston rod squeezes the gas in the air pressure sleeve to increase the gas pressure. When the surveyor is surveying around a large number of vehicles, the ground vibration generated by the vehicle driving will be transmitted to the piston rod, causing the piston rod to vibrate slightly, causing the piston rod to move slightly. When moving upward, the kinetic energy is absorbed by the compressibility of the high-pressure gas at the top of the piston rod, slowing down the vibration, thereby reducing the vibration of the surveyor, and effectively preventing the surveyor from vibrating frequently when surveying in an area with a large number of vehicles, thereby affecting the accuracy of the survey.

[0039] (2) The present invention is to solve the problem that when a large vehicle appears around the surveying instrument, the vibration amplitude of the piston rod will increase, resulting in a larger movement amplitude of the piston rod, which affects the level of the surveying instrument. When the piston rod rises, the rotating frame is tilted by pushing the assembly, and the placement assembly is pushed down, so that the support rod is lowered. As the piston rod continues to move, the support rod will contact the ground to provide additional support. When the piston rod is subjected to a larger vibration amplitude, the piston rod and the support rod rise at the same time. The rising support rod will cause the extrusion ring to fall, so that the piston rod and the extrusion ring perform bidirectional extrusion on the spring return rod, so that the extrusion ring applies a reaction force to the piston rod, reducing the movement amplitude of the piston rod, and effectively preventing the piston rod from having a large displacement amplitude, resulting in a slight tilt of the support leg, which affects the level of the surveying instrument.

[0040] (3) In the present invention, after the extrusion ring stops moving, the piston rod continues to rise, squeezing the spring return rod. The high-pressure gas in the air pressure sleeve will move to the top of the spring return rod. When the piston rod moves, the spring return rod will squeeze the gas in the sliding groove and enter the bottom of the piston rod. When the rebound force of the spring return rod is released, the piston rod returns to its original position. The high-pressure gas slows down the return speed of the spring return rod, effectively preventing the spring return force of the spring return rod from being released too quickly, causing the piston rod to quickly contact the ground and causing the piston rod to have an impact, which may cause secondary vibration and affect the stability of the surveying instrument during surveying. In addition, by discharging the gas at the bottom of the spring return rod, it is effectively prevented that the gas at the bottom of the spring return rod generates high pressure. The forces generated by the high-pressure gases at the top and bottom of the spring return rod offset each other, affecting the high-pressure gas to slow down the return speed.

[0052] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0053] For example 1, please refer to Figure 1-Figure 3 The present invention is a three-dimensional urban geological surveying and mapping device, comprising a placement platform 111, wherein three support legs 113 are rotatably connected to the inner wall of the placement platform 111;

[0054] A surveying and mapping mechanism 1, wherein a support assembly 11 is fixedly mounted on the top of the surveying and mapping mechanism 1, and a mounting assembly 12 is rotatably mounted on the inner wall of the surveying and mapping mechanism 1, and the support assembly 11 is used for surveying and mapping a three-dimensional geological map of the city;

[0055] A buffer mechanism 2 is installed at the bottom of the surveying and mapping mechanism 1 to reduce vibrations experienced by the support assembly 11; and

[0056] The horizontal mechanism 3 is located at the inner wall of the buffer mechanism 2 and is used to ensure the levelness of the surveying and mapping mechanism 1;

[0057] The bottom of each of the three support legs 113 is provided with a pneumatic sleeve 211. The three pneumatic sleeves 211 contain the same parts. A fixing ring 212 is fixedly connected to the inner wall of the pneumatic sleeve 211, and a piston rod 213 is slidably connected to the inner wall of the pneumatic sleeve 211.

[0058] Among them, the three-dimensional geological map of the city is surveyed by using the surveying and mapping mechanism 1. During the surveying, the vibration of the surveying and mapping mechanism 1 is reduced by the buffer mechanism 2, thereby reducing the vibration of the measuring instrument. This effectively prevents the surveying instrument 112 from vibrating frequently when surveying in an area with a large number of vehicles, thereby affecting the accuracy of the surveying. Finally, the leveling mechanism 3 is used to ensure that the surveying and mapping mechanism 1 is level during the surveying.

[0059] Surveying and mapping institutions 1 include:

[0060] Support assembly 11, the bottom of the support assembly 11 is fixedly arranged on the top of the placement table 111, and is used to support the measuring instrument;

[0061] The mounting assembly 12 is rotatably mounted on the inner wall of the placement table 111 at its outer wall for mounting a measuring instrument;

[0062] The support assembly 11 is opened to make the three support legs 113 stably contact the ground, and the support legs 113 are fixed by the mounting assembly 12 so that the measuring instrument is stably mounted on the support assembly 11 .

[0063] The buffer mechanism 2 includes:

[0064] An extrusion assembly 21 is slidably disposed on the inner wall of the air pressure sleeve 211 and is used to extrude gas;

[0065] A reset assembly 22 is slidably disposed on the inner wall of the air pressure sleeve 211 and is used to reset the extrusion assembly 21;

[0066] Among them, when the support component 11 is opened, the extrusion component 21 will be squeezed, squeezing the gas in the air pressure sleeve 211, causing the gas pressure to increase. The high-pressure gas will absorb the vibration of the support component 11, effectively preventing the measuring instrument from vibrating frequently when surveying in areas with a large number of vehicles, thereby affecting the accuracy of surveying.

[0067] The horizontal mechanism 3 includes:

[0068] A pushing assembly 31 is slidably disposed on the inner wall of the air pressure sleeve 211 and is used to limit the displacement distance of the extrusion assembly 21;

[0069] A placement assembly 32 is slidably disposed on the outer wall of the air pressure sleeve 211 for providing additional support at the bottom of the support leg 113;

[0070] Among them, when the extrusion component 21 rises, it will drive the pushing component 31 to rise, causing the placement component 32 to drop close to the ground until the placement component 32 contacts the ground, providing additional support, effectively preventing the piston rod 213 from displacing a large amplitude, causing the support leg 113 to tilt slightly, affecting the level of the measuring instrument.

[0071] For example 2, please refer to Figure 4-Figure 8 , the present invention is a three-dimensional urban geological mapping equipment. Based on Example 1, the support assembly 11 includes a surveying instrument 112 fixedly connected to the top of the placement platform 111;

[0072] The mounting assembly 12 includes three threaded knobs 121 that are threadedly connected to the inner wall of the placement platform 111, and the bottoms of the three support legs 113 are fixedly connected to round ball rods 122;

[0073] Among them, the three support legs 113 are rotated to open the support legs 113. After the support legs 113 are opened, the threaded knob 121 is rotated to move toward the support legs 113, squeezing the support legs 113, fixing the support legs 113, making the squeezing assembly 21 contact with the ground, and supporting the surveying instrument 112.

[0074] The extrusion assembly 21 includes a counterweight block 215 fixedly connected to the outer wall of the air pressure sleeve 211 , and the inner walls of the three air pressure sleeves 211 are rotatably connected to the outer walls of the three spherical rods 122 .

[0075] The extrusion assembly 21 further includes an extrusion ring 214 slidably connected to the inner wall of the air pressure sleeve 211 , and the outer wall of the piston rod 213 is slidably connected to the inner wall of the fixing ring 212 ;

[0076] Among them, by rotating the pneumatic sleeve 211, the pneumatic sleeve 211 is made perpendicular to the ground, and finally, the pneumatic sleeve 211 is placed down to make the piston rod 213 contact the ground. The pneumatic sleeve 211 is affected by the weight of the surveying instrument 112, the support legs 113 and the counterweight 215, and it will fall. Since the piston rod 213 is in a stationary state, the pneumatic sleeve 211 falls, and the piston rod 213 appears to rise relative to the pneumatic sleeve 211, allowing the piston rod 213 to squeeze the gas in the pneumatic sleeve 211, increasing the gas pressure. As the piston rod 213 continues to move, the gas pressure at the top of the piston rod 213 will increase until the piston rod 213 stops moving, causing the support legs 113 to fall. The legs 113 remain stable, stabilizing the surveying instrument 112, which then uses the surveying instrument 112 to survey a three-dimensional geological map of the city. When the surveying instrument 112 is surveying in an area with many vehicles, ground vibrations generated by vehicles traveling will be transmitted to the piston rod 213, causing the piston rod 213 to vibrate slightly. When the piston rod 213 moves slightly upward, the compressibility of the high-pressure gas at the top of the piston rod 213 absorbs kinetic energy, slowing down the vibration and thus reducing the vibration experienced by the surveying instrument 112. This effectively prevents the surveying instrument 112 from vibrating frequently when surveying in an area with many vehicles, thereby affecting the accuracy of the survey.

[0077] The reset assembly 22 includes a sliding groove 224 formed on the inner wall of the piston rod 213. The inner wall of the piston rod 213 is provided with an air hole 222. The inner wall of the sliding groove 224 is slidably connected to a spring reset rod 221.

[0078] A connecting hole 223 is formed on the inner wall of the piston rod 213, and the top of the spring return rod 221 is fixedly connected to the bottom of the extrusion ring 214;

[0079] Among them, when the extrusion ring 214 stops moving, the piston rod 213 continues to rise, squeezing the spring return rod 221. The high-pressure gas at the top of the piston rod 213 will enter the sliding groove 224 through the air hole 222 and move to the top of the spring return rod 221. The spring return rod 221 will squeeze the gas in the sliding groove 224 and enter the bottom of the piston rod 213 through the connecting hole 223. When the piston rod 213 is subjected to a large vibration force and disappears, the rebound force of the spring return rod 221 will be released, allowing the piston rod 213 to return to its original position. The high-pressure gas at the top of the spring return rod 221 slows down the return speed of the spring return rod 221, effectively preventing the spring return rod 221 from releasing the rebound force too quickly, causing the piston rod 213 to quickly contact the ground, causing the piston rod 213 to have an impact, which may cause secondary vibration and affect the stability of the surveying instrument 112 during surveying.

[0080] The pushing assembly 31 includes a connecting frame 311 slidably connected to the inner wall of the air pressure sleeve 211 , and the bottom of the connecting frame 311 is fixedly connected to the top of the extrusion ring 214 ;

[0081] A fixing frame 312 is fixedly connected to the outer wall of the air pressure sleeve 211, and a rotating frame 313 is rotatably connected to the outer wall of the fixing frame 312;

[0082] In order to solve the problem that when a large vehicle appears around the surveying instrument 112, the vibration amplitude of the piston rod 213 will increase, resulting in a larger movement amplitude of the piston rod 213 and affecting the level of the surveying instrument 112, when the piston rod 213 rises, it will drive the spring return rod 221 and the extrusion ring 214 to rise, and then let the connecting frame 311 rise, pushing the placement assembly 32 to descend.

[0083] The placement assembly 32 includes a connecting ring 321 disposed on the outer wall of the air pressure sleeve 211. Six support rods 322 are fixedly connected to the bottom of the connecting ring 321. A sliding rod 324 is fixedly connected to the top of the connecting ring 321. A sliding sleeve 323 is fixedly connected to the outer wall of the connecting ring 321.

[0084] The inner wall of the sliding sleeve 323 is slidably connected to the outer wall of the sliding rod 324, the top of the sliding rod 324 is slidably connected to the inner wall of the rotating frame 313, and the bottom of the connecting frame 311 is slidably connected to the inner wall of the rotating frame 313;

[0085] The connecting frame 311 pulls the rotating frame 313 to rotate, causing the rotating frame 313 to tilt, so that the side of the rotating frame 313 close to the connecting frame 311 rises and the other side falls. The falling side pushes the sliding rod 324 to fall, so that the sliding rod 324 pushes the connecting ring 321 and the support rod 322 to fall. As the connecting frame 311 continues to rise, the connecting frame 311 will be blocked by the air pressure sleeve 211, causing the connecting frame 311 to stop moving, and the extrusion ring 214 to stop moving. At this time, the piston rod 213 continues to rise, which will squeeze the spring return rod 221, causing the spring return rod 221 to accumulate resilience. As the piston rod 213 continues to move, the support rod 322 will contact the ground to provide additional support, such as: Figure 7 As shown, when the piston rod 213 is subjected to a large vibration amplitude, the piston rod 213 and the support rod 322 rise at the same time. The rise of the support rod 322 will cause the extrusion ring 214 to drop, causing the piston rod 213 and the extrusion ring 214 to squeeze the spring return rod 221 at the same time, and perform bidirectional squeezing on the spring return rod 221, applying a reaction force to the piston rod 213, reducing the movement amplitude of the piston rod 213, and effectively preventing the piston rod 213 from being displaced by a large amplitude, causing the support leg 113 to tilt slightly, affecting the level of the surveying instrument 112.

[0086] There is no limit on the number of the above components, and relevant technicians in this field can freely set them according to actual needs, as long as the above components are installed in the corresponding component connection positions.

[0087] A specific application of this embodiment is as follows: when the present invention is used, the operator moves the device to the position that needs to be surveyed and mapped. After moving to the position, the operator rotates the three support legs 113 to open the support legs 113. After the support legs 113 are opened, the threaded knob 121 is rotated to move toward the support legs 113, squeezing the support legs 113 to fix the support legs 113. Then, the pneumatic sleeve 211 is rotated to make the pneumatic sleeve 211 perpendicular to the ground. Finally, the pneumatic sleeve 211 is lowered to make the piston rod 213 contact the ground. The pneumatic sleeve 211 is affected by the weight of the surveying instrument 112, the support legs 113 and the counterweight 215, and it will fall. Since the piston rod 213 is in a stationary state, the pneumatic sleeve 211 falls, and the piston rod 213 appears to rise relative to the pneumatic sleeve 211, allowing the piston rod 213 to squeeze the pneumatic sleeve 211. The gas inside increases the gas pressure. As the piston rod 213 continues to move, the gas pressure at the top of the piston rod 213 increases until the piston rod 213 stops moving, thereby keeping the support legs 113 stable and stabilizing the surveying instrument 112. The three-dimensional geological map of the city is then surveyed by the surveying instrument 112. When the surveying instrument 112 is surveying in an area with many vehicles, the ground vibrations generated by the vehicles traveling are transmitted to the piston rod 213, causing the piston rod 213 to vibrate slightly. When the piston rod 213 moves slightly and moves upward, the kinetic energy is absorbed by the compressibility of the high-pressure gas at the top of the piston rod 213, slowing down the vibration, thereby reducing the vibration suffered by the surveying instrument 112. This effectively prevents the surveying instrument 112 from vibrating frequently when surveying in an area with many vehicles, thereby affecting the accuracy of the surveying.

[0088] Secondly, in order to solve the problem that when a large vehicle appears around the surveying instrument 112, the vibration amplitude of the piston rod 213 will increase, resulting in a large movement amplitude of the piston rod 213, which affects the level of the surveying instrument 112, when the piston rod 213 rises, it will drive the spring return rod 221 and the extrusion ring 214 to rise, and when the connecting frame 311 rises, the connecting frame 311 will pull the rotating frame 313 to rotate, causing the rotating frame 313 to tilt, so that the side of the rotating frame 313 close to the connecting frame 311 rises and the other side falls, and the falling side The sliding rod 324 is pushed down, and the sliding rod 324 pushes the connecting ring 321 and the support rod 322 down. As the connecting frame 311 continues to rise, the connecting frame 311 is blocked by the air pressure sleeve 211, causing the connecting frame 311 to stop moving, and the extrusion ring 214 to stop moving. At this time, the piston rod 213 continues to rise, which squeezes the spring return rod 221, causing the spring return rod 221 to accumulate resilience. As the piston rod 213 continues to move, the support rod 322 contacts the ground, providing additional support, such as: Figure 7As shown, when the piston rod 213 is subjected to a large vibration amplitude, the piston rod 213 and the support rod 322 rise simultaneously. The rise of the support rod 322 causes the extrusion ring 214 to descend, causing the piston rod 213 and the extrusion ring 214 to simultaneously squeeze the spring return rod 221. The spring return rod 221 is squeezed in both directions, exerting a reaction force on the piston rod 213, reducing the movement amplitude of the piston rod 213, and effectively preventing the piston rod 213 from being displaced too much, causing the support leg 113 to tilt slightly, thereby affecting the level of the surveying instrument 112.

[0089] Secondly, when the extrusion ring 214 stops moving, the piston rod 213 continues to rise, squeezing the spring return rod 221. The high-pressure gas at the top of the piston rod 213 will enter the sliding groove 224 through the air hole 222 and move to the top of the spring return rod 221. The spring return rod 221 will squeeze the gas in the sliding groove 224 and enter the bottom of the piston rod 213 through the connecting hole 223. When the large vibration force on the piston rod 213 disappears, the rebound force of the spring return rod 221 will be released, allowing the piston rod 213 to return to its original position. The high-pressure gas at the top of the spring return rod 221 will slow down the spring return rod 2 21, effectively preventing the spring return rod 221 from releasing its rebound force too quickly, causing the piston rod 213 to quickly contact the ground, causing the piston rod 213 to have an impact, which may cause secondary vibration and affect the stability of the surveying instrument 112 during surveying; in addition: by discharging the gas in the sliding groove 224 into the bottom of the piston rod 213 through the connecting hole 223, it is effectively prevented that the gas in the sliding groove 224 is squeezed to generate high pressure, resulting in that when the spring return rod 221 returns, the force generated by the high-pressure gas at the top and bottom of the spring return rod 221 offsets each other, affecting the high-pressure gas to slow down the return speed of the spring return rod 221.
