Description

Technical Field

[0001] This utility model relates to the technical field of ground leveling, and in particular to a leveling platform structure for irregular ground. Background Technology

[0002] In the machining of larger parts, to ensure machining accuracy, such as opening holes in cylindrical planes, the flatness of the machining platform is crucial to improve machining precision. However, machining on a surface can be challenging due to irregularities, which can negatively impact accuracy. Therefore, when using a machining platform on the ground, leveling is necessary. Existing leveling methods typically involve rotating bolts at the feet, which is not only difficult to tighten but also prone to incomplete leveling.

[0003] Chinese Patent Publication No. CN214216525U, published on September 17, 2021, discloses an automatically leveling steel platform, including a base plate. The platform is characterized by: a support column on one side of the top of the base plate; a top plate at the top of the support column; an angle balancer at the bottom of the top plate; a first rotating rod on one side of the support column; a second rotating rod on one side of the first rotating rod; a sleeve at the bottom of the top plate and on the side of the second rotating rod; and a hydraulic telescopic rod at the top of the base plate and on the side of the support column. The drawback of this invention is that the leveling process relies solely on observation, which can easily lead to incomplete leveling. Utility Model Content

[0004] The present invention aims to overcome the shortcomings of existing technologies where it is difficult to confirm whether the leveling is in place during leveling, and provides a leveling platform structure for irregular ground that facilitates confirmation of whether the platform's flatness meets the standards during leveling.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: An irregular ground leveling platform structure includes: Shelf; A lifting assembly, wherein several lifting assemblies are provided and arranged in a circular pattern, and the upper end of the lifting assembly is rotatably connected to the bottom surface of the shelf. A support column, the upper end of which is connected to the lifting assembly; A pressure detection component is installed at the bottom of the support column.

[0006] The shelf is used to place workpieces. Adjusting the shelf ensures the workpieces are flat. A circumferentially distributed lifting assembly adjusts the tilt of the shelf. The shelf is adjusted by varying the lifting distance of the lifting assemblies at different positions. The lifting assemblies are mounted on support columns, ensuring the shelf's stability through contact with the ground. Pressure detection components are installed at the bottom of the support columns to detect the pressure on each column when in contact with the ground. When the shelf is tilted, the pressure on each support column is inconsistent. The lifting assembly on the support column with the higher pressure raises one side of the shelf until the pressure on the pressure detection assembly is consistent. When the pressure on each support column is consistent, the shelf is level. This process is repeated to achieve the goal of leveling the shelf and facilitating confirmation of the platform's flatness.

[0007] Preferably, the bottom surface of the shelf is equipped with connecting blocks, each corresponding to a lifting component. Each connecting block has a rotating groove. The lifting component includes a lifting column and a rotating ball. The rotating ball is mounted on the top of the lifting column, and the lifting column is rotatably connected to the connecting blocks via the cooperation of the rotating ball and the rotating groove. The connecting blocks, arranged circumferentially on the shelf, correspond one-to-one with the lifting columns of the lifting component. The lifting columns are rotatably connected to the connecting blocks via the cooperation of the rotating ball and the rotating groove. When the lifting column rises or falls, the connecting blocks can rotate on the rotating ball. This prevents the shelf from rising as a whole when adjusting it, allowing for targeted adjustment of the shelf's angle. This design enables targeted adjustment of the shelf's angle.

[0008] Preferably, the top of the support column is provided with a lifting groove, and a pneumatic cylinder is installed in the lifting groove. The pneumatic end of the pneumatic cylinder is connected to the bottom surface of the lifting column. The lower end of the lifting column is placed in the lifting groove, and a force-bearing block is installed on the bottom surface of the support column. The force-bearing block is shaped like a frustum. The lower end of the lifting column is placed in the support groove of the support column. The pneumatic cylinder in the support groove can push the lifting column to slide and rise within the support groove, thereby adjusting the shelf through the lifting column. The frustum-shaped force-bearing block installed at the lower end of the support column increases the force-bearing area by contacting the ground, thus ensuring the stability of the support column. This design can drive the lifting column to rise and fall.

[0009] Preferably, the pressure detection assembly includes a pressure sensor and a contact plate. The bottom surface of the force-bearing block has a mounting groove, and the pressure sensor is installed in the mounting groove. The pressing end of the pressure sensor is located outside the mounting groove and is connected to the contact plate. The pressure detection assembly is installed at the bottom of the support column. The pressure sensor, located in the mounting groove at the bottom of the support column, is connected to the contact plate. The contact plate is positioned below the support plate and directly contacts the ground, thereby detecting the pressure on the support column. The contact between the contact plate and the ground protects the pressure sensor and increases the contact area to improve detection accuracy. This design can detect the pressure on the support column.

[0010] Preferably, the contact plate is equipped with several circumferentially distributed limiting posts. One end of each limiting post is connected to the contact plate, and the other end penetrates the bottom surface of the force-bearing block and is positioned on the other side of the force-bearing block. Movement during processing can cause the support column to sway, leading to misalignment between the support column and the contact plate, which could damage the pressure sensor. Therefore, limiting posts are installed on the contact plate, penetrating the force-bearing block at the lower end of the support column. This ensures that the contact sensor can only move linearly along the limiting posts, preventing misalignment of the contact plate.

[0011] Preferably, the support column is provided with a retaining ring, which has an inner ring, an outer ring, and connecting rods. The inner ring is connected to the inner side of the support column, and the outer ring is connected to the outer side of the support column. Several connecting rods are provided and arranged circumferentially, with one end connected to the inner ring and the other end connected to the outer ring. Because the support columns are circumferentially distributed, they are prone to shifting when the shelf is under stress. Therefore, the retaining rings connect the support columns together to ensure their position. The inner and outer rings of the retaining ring are placed on both sides of the support, and all support columns are placed between the inner and outer rings. The inner and outer rings are connected by a connecting plate to ensure the strength of the retaining ring. This design can restrict the position of the support columns.

[0012] The beneficial effects of this utility model are: it makes it easy to confirm whether the flatness of the platform meets the standard during leveling, it allows for targeted adjustment of the angle of the shelf, it can drive the lifting column to rise and fall, it can detect the pressure on the support column, it can prevent the contact plate from shifting, and it can limit the position of the support column.
