Abstract
Description
Technical Field
[0001] This application relates to the field of platform support and balance adjustment, and in particular to an automatic balancing support device. Background Technology
[0002] In the use of precision instruments, the flatness of the ground has a significant impact on the measurement accuracy and performance of the instruments. With the continuous development of technology, high-precision instruments are widely used in various fields. For example, in field operations and laboratory environments, increasingly higher demands are placed on the speed and accuracy of instrument leveling. In industrial production, the precise measurement of high-precision instruments is crucial for product quality control, and the accuracy and speed of leveling directly affect production efficiency and product qualification rates. In scientific research, especially in experiments with demanding environmental requirements, precise instrument leveling ensures the accuracy and reliability of experimental data, thereby promoting scientific research progress.
[0003] To address the leveling issues of precision instruments, several common leveling methods exist. One traditional method is manual leveling with a three-legged support, where operators adjust the height by rotating threaded rods on the legs. This method requires meticulous manual adjustment, making it tedious and time-consuming. For some large instruments, operators may need to repeatedly adjust the height of multiple supports to achieve a basic level. Another method involves hydraulic or pneumatic leveling systems. These systems utilize hydraulic or pneumatic devices to achieve automatic leveling, increasing the degree of automation. Hydraulic or pneumatic systems typically require complex piping and control valves, adjusting the support height through changes in liquid or gas pressure.
[0004] However, existing leveling methods still have significant drawbacks in practical applications. Especially for leveling precision instruments, manual leveling is inefficient, cumbersome, and difficult to achieve fast and accurate leveling. Furthermore, hydraulic or pneumatic leveling systems are bulky, making them inconvenient to transport to testing areas and complex to maintain. Hydraulic systems require regular checks of hydraulic oil quality and pressure, while pneumatic systems require stable air supply and leak-proof piping; problems in any of these areas can affect the leveling effect. Utility Model Content
[0005] To ensure the accuracy of instrument leveling, improve the efficiency and convenience of instrument leveling, and reduce the maintenance cost of the leveling device, this application provides an automatic balancing support device.
[0006] This application provides an automatic balancing support device, including: a positioning platform, a support platform, and a balancing locking structure. The positioning platform, used to hold the instrument, has a first adjustment structure at its bottom, and the support platform has a second adjustment structure at its top. The balancing locking structure is detachably mounted on the second adjustment structure, and the first adjustment structure and the balancing locking structure are coaxially arranged. When the positioning platform is placed on top of the support platform, the first adjustment structure inserts into the balancing locking structure until the balancing locking structure and the second adjustment structure achieve a coaxial locking state. The balancing locking structure quickly adjusts to a vertical position. The balancing locking structure uses its own weight to ensure coaxial engagement between the first and second adjustment structures and applies torque to achieve automatic leveling of the positioning platform. By adopting the above technical solution, the first adjustment structure at the bottom of the positioning platform and the detachably mounted balancing locking structure on the second adjustment structure at the top of the support platform are coaxially arranged. When the positioning platform is placed on top of the support platform, the first adjustment structure inserts into the balancing locking structure. Because the balancing locking structure has an adjustable characteristic, it quickly adjusts to a vertical position during insertion. Based on the principle of gravity, the center of gravity of an object naturally tends to point vertically downwards. This center of gravity adjustment of the balance locking structure enables it to achieve a coaxial locking state with the second adjustment structure. After achieving the coaxial locking state, the balance locking structure uses its own gravity to make the first and second adjustment structures coaxially engage. Because under the action of gravity, the balance locking structure causes the axes of the first and second adjustment structures to coincide. At the same time, the balance locking structure also applies torque under the action of gravity, which generates an adjustment force on the positioning platform, thereby achieving automatic leveling of the positioning platform. This avoids the tedious process of careful manual adjustment, improves leveling efficiency, and achieves fast and accurate leveling. Compared with existing hydraulic or pneumatic leveling systems, it does not require complex pipes and control valves, has a simpler structure, is easier to transport to the testing area, and is more convenient to maintain. Preferably, the first adjustment structure includes an integrally formed guide column and a guide cone. The top of the guide column is connected to the bottom of the positioning platform, and the bottom of the guide column is coaxially provided with a guide cone, the tip of which faces the balance locking structure. By adopting the above technical solution, the guide column and guide cone are integrally formed and set at the bottom of the positioning platform, with the tip of the guide cone facing the balance locking structure. When the positioning platform is placed on top of the support platform, the tip of the guide cone can first contact the balance locking structure and play a preliminary positioning role. Since the guide column and guide cone are coaxially set, as the positioning platform continues to be placed downward, the guide column can accurately insert into the balance locking structure along the direction of preliminary positioning, ensuring the coaxial insertion of the first adjustment structure and the balance locking structure. This facilitates the subsequent use of the balance locking structure's own gravity to make the first adjustment structure and the second adjustment structure coaxially cooperate, thereby realizing the automatic leveling of the positioning platform.Preferably, the balance locking structure includes a gravity block and a hemisphere. The top of the gravity block is detachably connected to the arc-shaped bottom of the hemisphere. A limiting groove for accommodating the guide post and guide cone is provided in the middle of the hemisphere, and the shape of the limiting groove is adapted to the shape of the guide post and guide cone. By adopting the above technical solution, since the balance locking structure includes a gravity block and a hemisphere, the top of the gravity block is detachably connected to the arc-shaped bottom of the hemisphere, and a limiting groove adapted to the shape of the guide post and guide cone is provided in the middle of the hemisphere, when the positioning platform is placed on top of the support platform, and the guide post and guide cone of the first adjustment structure are inserted into the limiting groove, the gravity block will quickly adjust the balance locking structure to a vertical position due to its own weight. During this process, the gravity of the gravity block causes the balance locking structure to drive the first adjustment structure and the second adjustment structure to cooperate coaxially and apply torque, thereby realizing automatic leveling of the positioning platform. This structural design can effectively improve the automation and efficiency of leveling. Preferably, the second adjustment structure includes a hemispherical base protruding from the bottom of the support platform. The hemispherical base has an upward-facing opening and a through hole in its center. A connecting column is located on the top of the gravity block, and the connecting column passes through the through hole and is detachably connected to the gravity block. By adopting the above technical solution, since the hemispherical base of the second adjustment structure protrudes from the bottom of the support platform and has an upward-facing opening with a through hole in its center, and the connecting column on the top of the gravity block passes through the through hole and is detachably connected to the gravity block, this structure allows the gravity block to be stably connected to the second adjustment structure and is easy to install and disassemble. When the positioning platform is placed on top of the support platform for leveling, the gravity block can swing flexibly under its own weight, thereby driving the balance locking structure to quickly adjust to the vertical position of the center of gravity, so that the first adjustment structure and the second adjustment structure are coaxially coordinated, ultimately achieving automatic leveling of the positioning platform. Preferably, the hemisphere has a locking ball and a sliding cavity inside, and the hemispherical base has a locking groove circumferentially arranged corresponding to the locking ball. The locking ball slides within the sliding cavity, which is connected to both the limiting groove and the locking groove. When the guide post is inserted into the limiting groove, the guide post compresses the locking ball exposed on the groove wall until the locking ball slides to abut against the locking groove, thus achieving locking. By adopting the above technical solution, when the guide post is inserted into the limiting groove, because the sliding cavity is connected to the limiting groove, the guide post compresses the locking ball exposed on the groove wall. The locking ball can slide within the sliding cavity, which is connected to the locking groove. After being compressed, the locking ball slides within the sliding cavity until it abuts against the locking groove, thereby achieving locking between the hemisphere and the hemispherical base. This ensures that the balance locking structure will not wobble or rotate after being locked in a vertical position, which helps to improve the stability and reliability of the entire support device after automatic leveling. Preferably, there are four locking balls distributed circumferentially. By adopting the above technical solution, the four locking balls are distributed circumferentially, so that when the guide post is inserted into the limiting groove to squeeze the locking ball, the hemisphere and the hemisphere base can be locked from multiple circumferential positions.Because of the circumferentially uniform distribution, the compressive force on each locking ball is more even, allowing it to slide more stably until it abuts against the locking groove, achieving reliable locking between the hemisphere and the hemisphere base, thus ensuring the stability of the entire support structure after leveling. Preferably, the locking ball has a protrusion extending from one end toward the hemisphere base, which abuts against the groove wall of the locking groove, and the shape of the protrusion matches the shape of the locking groove. By adopting the above technical solution, when the guide post is inserted into the limiting groove, the guide post compresses the locking ball exposed on the groove wall, causing the locking ball to slide within the sliding cavity. Because the locking ball has a protrusion extending from one end toward the hemisphere base, and the shape of the protrusion matches the shape of the locking groove, when the locking ball slides to abut against the locking groove, the protrusion can better fit against the groove wall, thus achieving a more stable lock, effectively preventing relative displacement between the balancing locking structure and the second adjustment structure, and improving the stability and reliability of the automatic balancing support device during the leveling process. Preferably, the opening diameters at the junctions of the sliding cavity and the limiting groove, and the sliding cavity and the locking groove, are both smaller than the diameter of the locking ball. By adopting the above technical solution, since the opening diameters at the junctions of the sliding cavity and the limiting groove, and the locking groove, are both smaller than the diameter of the locking ball, the locking ball will not detach from the sliding cavity at the junctions with the limiting groove and the locking groove when sliding within the sliding cavity. This ensures that the locking ball can only slide within the sliding cavity along the designed path, so that when the guide post is inserted into the limiting groove and presses against the locking ball, the locking ball can accurately slide to abut against the locking groove to achieve locking. Preferably, the top of the positioning platform is provided with three positioning grooves for placing the instrument. The centers of the three positioning grooves and the axis of the guide post are all located on the center of gravity axis of the instrument. By adopting the above technical solution, since the top of the positioning platform is provided with three positioning grooves for placing the instrument, and the centers of the three positioning grooves and the axis of the guide post are all located on the center of gravity axis of the instrument, this ensures that after the instrument is placed in the positioning groove, its center of gravity accurately corresponds to the axis of the guide post. As part of the first adjustment structure, the guide column, in conjunction with the balance locking structure and the second adjustment structure, enables more precise guidance of the balance locking structure to quickly adjust to a vertical position during automatic leveling. This, due to the correspondence between the instrument's center of gravity and the guide column's axis, allows the balance locking structure to more effectively use its own weight to ensure coaxial alignment between the first and second adjustment structures and apply torque, thus achieving more accurate and efficient automatic leveling of the positioning platform. Preferably, the bottom of the positioning platform has four guide rods, and the support platform has corresponding guide holes for each guide rod. The guide rods pass through these guide holes, and each guide rod is hinged to the bottom of the positioning platform via a ball joint. By adopting the above technical solution, the positioning platform has four guide rods at its bottom, the support platform has corresponding guide holes, the guide rods pass through these guide holes, and each guide rod is hinged to the bottom of the positioning platform via a ball joint.During the leveling process where the positioning platform is placed on top of the support platform, the ball joint structure allows the guide rods to rotate flexibly at multiple angles. When the positioning platform is automatically leveled under the action of the balance locking structure, the guide rods can adaptably slide and rotate within the guide holes, avoiding any obstruction to the leveling of the positioning platform. At the same time, the four guide rods can guide and support the positioning platform from multiple directions, making the positioning platform more stable during the leveling process, reducing swaying and offset, and thus achieving automatic leveling more accurately and quickly.
[0007] In summary, this application includes at least one of the following beneficial technical effects:
[0008] 1. Since the balance locking structure and the first adjustment structure are coaxially arranged, when the positioning platform is placed on top of the support platform, the first adjustment structure is inserted into the balance locking structure. The balance locking structure can quickly adjust to the vertical position of the center of gravity under the action of gravity, and through its own gravity, the first adjustment structure and the second adjustment structure are coaxially matched and torque is applied, so as to realize the rapid leveling of the positioning platform, which solves the problems of low efficiency and troublesome operation of manual leveling.
[0009] 2. The design of the locking ball inside the hemisphere allows for flexible sliding, achieving automatic locking after leveling. This improves the convenience and accuracy of leveling, and the structure is simple and easy to operate, reducing the difficulty of debugging and maintenance. Attached Figure Description

[0015] The following is in conjunction with the appendix Figure 1-4This application will be described in further detail.
[0016] This application provides an embodiment of an automatic balancing support device, referring to... Figure 1 and Figure 2 It includes a positioning platform 1, a support platform 2, and a balance locking structure 3. The positioning platform 1 places the instrument in a preset position, the support platform 2 supports the positioning platform 1, and the balance locking structure 3 is set between the positioning platform 1 and the support platform 2 to quickly adjust the horizontal balance of the positioning platform 1.
[0017] Specifically, in this embodiment, the positioning platform 1 has a first adjustment structure 11 at its bottom, which includes an integrally formed guide post 111 and a guide cone 112. The top of the guide post 111 is connected to the bottom of the positioning platform 1, and the guide post 111 can be securely connected to the positioning platform 1 by welding, bolting, or other methods to ensure that the two will not separate during the leveling process. The guide cone 112 is coaxially arranged at the bottom of the guide post 111, with the tip of the guide cone 112 facing the balance locking structure 3. The guide post 111 is cylindrical. The guide cone 112 is conical, which facilitates the insertion of the balance locking structure 3. The integral design of the guide post 111 and the guide cone 112 ensures the integrity and stability of the structure, ensures that the guide post 111 and the guide cone 112 are coaxial, and can better transmit force when the balance locking structure 3 is inserted.
[0018] Specifically, in this embodiment, the positioning platform 1 has three positioning slots 12 on its top. These slots are used to place the instrument, and the centers of the three slots 12 and the axis of the guide column 111 are all located on the instrument's center of gravity axis. The positioning slots 12 are circular or square, and their depth and size are designed according to the shape and size of the instrument's bottom to ensure that the instrument can be stably placed on the positioning platform 1. The fact that the centers of the three positioning slots 12 and the axis of the guide column 111 are located on the instrument's center of gravity axis ensures that the instrument is subjected to uniform force during leveling, improving the accuracy of leveling. When the instrument is placed in the three positioning slots 12, the instrument's weight is evenly transmitted to the positioning platform 1 through the three slots 12. Furthermore, since the axis of the guide column 111 is also on the center of gravity axis, the positioning platform 1 can be smoothly adjusted around the instrument's center of gravity during leveling.
[0019] Specifically, the positioning platform 1 has four guide rods 13 at its bottom. Each guide rod 13 penetrates the support platform 2 to improve the stability of the positioning platform 1 during the leveling process. Each guide rod 13 is hinged to the bottom of the positioning platform 1 via a ball joint structure. The guide rod 13 is cylindrical. The ball joint structure allows the guide rod 13 to rotate flexibly within a certain range. When the positioning platform 1 is tilted during leveling, the guide rod 13 can adjust its angle according to the tilt of the positioning platform 1, while also serving a guiding function to ensure that the positioning platform 1 moves smoothly during the leveling process. The guide rod 13 is connected to the bottom of the positioning platform 1 via the ball joint structure, allowing the guide rod 13 to rotate relative to the positioning platform 1 in multiple directions. When the positioning platform 1 is tilted, the flexible rotation of the guide rod 13 guides the positioning platform 1 to level in the correct direction, avoiding swaying or deviation.
[0020] Specifically, in this embodiment, the support platform 2 is provided with a second adjustment structure 21 at its top, and a guide hole 22 is provided corresponding to the guide rod 13. The four guide holes 22 are rectangularly distributed on the support platform 2, facilitating the guide rod 13 to pass through the guide holes 22 from top to bottom. The second adjustment structure 21 includes a hemispherical base 211 protruding from the bottom of the support platform 2. The hemispherical base 211 has an upward opening and a through hole 212 in its middle. The inner wall of the hemispherical base 211 is evenly provided with a plurality of locking grooves 213. The hemispherical base 211 can be integrally formed with the support platform 2 by casting or machining, or it can be fixed to the support platform 2 by welding or other methods. In this embodiment, the support platform 2 is provided with four supports 23 at its bottom. The four supports 23 are rectangularly arranged to stably support the support platform 2.
[0021] Specifically, the balance locking structure 3 in this embodiment includes a gravity block 31, a hemisphere 32, and a connecting post 33. The top of the gravity block 31 is detachably connected to the connecting post 33, and the top of the connecting post 33 is connected to the arc-shaped bottom of the hemisphere 32. This detachable connection can be a threaded connection, facilitating replacement or repair of the gravity block 31 or the hemisphere 32 when needed. During installation, the connecting post 33 passes through the through hole 212 of the hemisphere base 211 from top to bottom and is threadedly connected to the gravity block 31 located at the bottom of the hemisphere base 211. A limiting groove 321 is provided in the middle of the hemisphere 32 to accommodate the guide post 111 and the guide cone 112. The shape of the limiting groove 321 is adapted to the shape of the guide post 111 and the guide cone 112. The gravity block 31 is usually a solid structure made of a high-density metal material, such as lead or iron, to ensure that it has sufficient gravity to achieve the leveling function. The limiting groove 321 is coaxial with the guide post 111 and the guide cone 112. The function of the limiting groove 321 is to limit the guide post 111 and the guide cone 112 so that they will not deviate during the insertion process and ensure the accuracy of leveling.
[0022] Specifically, the shape of the hemispherical base 211 is designed to match the shape of the hemisphere 32. In this embodiment, the diameter of the through hole 212 is larger than the diameter of the connecting column 33, but much smaller than the diameter of the hemisphere 32. When the support platform 2 cannot be guaranteed to be placed horizontally, the gravity block 31 needs to drive the connecting column 33 to a vertical position under its own weight. The connecting column 33 can be flexibly adjusted within the through hole 212, and the hemisphere 32 can swing flexibly within a certain range within the hemispherical base 211, thereby adjusting the gravity block 31, the connecting column 33, and the hemisphere 32 to a vertical position. This ensures that the limiting groove 321 within the hemisphere 32 remains vertically aligned, and the guide column 111 within the limiting groove 321 remains vertically aligned, thus achieving automatic leveling of the positioning platform 1.
[0023] Reference Figure 3 and Figure 4 Specifically, the hemisphere 32 has four locking balls 322 and four sliding cavities 323 inside. The four locking balls 322 are circumferentially distributed, and the limiting groove 321 is located at the center line of the four locking balls 322. The hemisphere base 211 has several locking grooves 213 circumferentially arranged. The locking balls 322 slide in the sliding cavities 323, which are connected to the limiting grooves 321 and the locking grooves 213 respectively. A protrusion 3221 extends from one end of the locking ball 322 toward the hemisphere base 211. The protrusion 3221 abuts against the groove wall of the locking groove 213, and the shape of the protrusion 3221 matches the shape of the locking groove 213. The sliding cavity 323 is inclined upwards. When the guide post 111 is inserted into the limiting groove 321, the guide post 111 presses against the locking ball 322 exposed on the groove wall of the limiting groove 321, until the locking ball 322 slides upwards and abuts against the locking groove 213. The protrusion 3221 is precisely embedded in the locking groove 213, tightly fitting against the groove wall to achieve locking. When the guide post 111 is removed, the locking ball 322 falls back along the sliding cavity 323 under its own weight, with at least a portion exposed in the limiting groove 321. The locking ball 322 is generally a metal sphere, such as a steel ball, with high hardness and wear resistance. The inner wall of the sliding cavity 323 should be smooth to reduce the friction when the locking ball 322 slides. The shape of the locking groove 213 is adapted to the locking ball 322, accurately accommodating the locking ball 322 and realizing the locking function. When the guide post 111 is inserted into the limiting groove 321, the outer circumferential surface of the guide post 111 will contact the locking ball 322 exposed on the groove wall of the limiting groove 321. As the guide post 111 continues to go deeper, it generates a radial extrusion force on the locking ball 322, forcing the locking ball 322 to slide along the smooth sliding cavity 323 towards the locking groove 213 until the locking ball 322 is completely inserted into the locking groove 213. At this time, the hemisphere 32 and the hemisphere base 211 are locked.
[0024] Specifically, the opening diameters at the junctions of the sliding cavity 323 and the limiting groove 321, and between the sliding cavity 323 and the locking groove 213, are both smaller than the diameter of the locking ball 322. This design prevents the locking ball 322 from dislodging from the sliding cavity 323, ensuring the stability of the locking structure. When the locking ball 322 slides within the sliding cavity 323, because the diameters of these two openings are smaller than the diameter of the locking ball 322, the locking ball 322 can only slide back and forth within the sliding cavity 323 and will not fall out from the openings.
[0025] With the cooperation of the balance locking structure 3, the first adjustment structure 11 and the balance locking structure 3 are arranged coaxially. When the positioning platform 1 is placed on top of the support platform 2, the first adjustment structure 11 is inserted into the balance locking structure 3, so that the balance locking structure 3 and the second adjustment structure 21 are locked together. The balance locking structure 3 is quickly adjusted to a vertical position of center of gravity. Through its own gravity, the first adjustment structure 11 and the second adjustment structure 21 are coaxially engaged, and torque is applied to achieve automatic leveling of the positioning platform 1. This structural cooperation method can utilize the gravity characteristics of the balance locking structure 3 to quickly and accurately level the positioning platform 1.
[0026] The implementation principle of this embodiment is as follows: The support device of this embodiment includes a positioning platform 1, a support platform 2 and a balance locking structure 3. The positioning platform 1 has a first adjustment structure 11 with an integrally formed guide column 111 and guide cone 112 at the bottom, and three positioning grooves 12 at the top. The center of the grooves and the axis of the guide column 111 are located on the axis of the instrument's center of gravity. The bottom also has four guide rods 13 connected by a ball joint structure. The support platform 2 has a second adjustment structure 21 at the top, with rectangular guide holes 22 corresponding to the guide rods 13. The second adjustment structure 21 includes a hemispherical base 211 that protrudes from the bottom of the support platform 2, faces upward, and has a through hole 212 in the middle. The inner wall of the hemispherical base 211 has a locking groove 213, and the bottom has four rectangular brackets 23. The balance locking structure 3 includes a gravity block 31, a hemisphere 32, and a connecting column 33. The gravity block 31 is connected to the connecting column 33, and the connecting column 33 is detachably connected to the gravity block 31. During installation, the connecting column 33 passes through the through hole 212 of the hemispherical base 211 and connects to the gravity block 31. The hemispherical body 32 has a limit groove. 321, whose shape is adapted to the guide post 111 and guide cone 112, and the hemispherical base 211 whose shape is adapted to the hemisphere 32, the diameter of the through hole 212 is larger than the connecting post 33 and much smaller than the diameter of the hemisphere 32, which facilitates the adjustment of the gravity block 31 and other components in the vertical position of the center of gravity to achieve automatic leveling of the positioning platform 1. Inside the hemisphere 32, there are also four circumferentially distributed locking balls 322 and four sliding cavities 323. The locking balls 322 slide in the sliding cavities 323 and are adapted to the locking grooves 213 of the hemispherical base 211. The guide post 111 can squeeze the locking balls 322 to achieve locking by inserting the limiting groove 321. The opening diameter of the sliding cavity 323 is smaller than the diameter of the locking ball 322 at the connection between the limiting groove 321 and the locking groove 213. This device, through the cooperation of the balance locking structure 3, makes the first adjustment structure 11 and the balance locking structure 3 coaxially arranged. When the positioning platform 1 is placed, the first adjustment structure 11 is inserted into the balance locking structure 3 to achieve rapid and accurate leveling.
[0027] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
