Description

Technical Field

[0001] This utility model belongs to the field of construction surveying technology, and in particular relates to a mobile surveying platform. Background Technology

[0002] In the field of engineering construction, construction survey control points are crucial benchmarks for ensuring project accuracy. Currently, commonly used survey control points mainly employ fixed locations using concrete structures or steel pipes. Concrete structures stabilize the survey markers by pouring concrete, while steel pipes achieve measurement positioning by burying or fixing steel pipes in the ground. While both methods ensure relatively stable and reliable control point placement, the fixed locations of these control points are problematic. Construction sites are complex and constantly changing. As construction progresses, temporary facilities such as tower cranes and material storage areas are frequently adjusted, easily obstructing the line of sight between control points. This hinders surveying and setting out, impacting construction progress and measurement accuracy. Furthermore, in construction areas with high requirements for protecting finished products, such as interior decoration and municipal engineering projects, concrete pouring or steel pipe installation can damage existing finished products, failing to meet construction specifications and making traditional survey control points unsuitable for these areas.

[0003] Therefore, designing a measurement platform that enables the free movement of measurement control points is of great significance for engineering surveying. Utility Model Content

[0004] To address the shortcomings of related technologies, this utility model provides a movable measurement platform that moves the measurement control point by driving the forced centering plate to move.

[0005] This utility model provides a portable measurement platform, including:

[0006] Installation platform;

[0007] The forced centering plate is mounted on the mounting platform; the forced centering plate is used to form measurement control points.

[0008] The rollers are located at the bottom of the mounting platform and are in contact with the ground to move the mounting platform and the centering plate.

[0009] This technical solution involves setting a forced centering plate above the mounting platform to form a measurement control point, and installing rollers at the bottom of the mounting platform to move the mounting platform, thereby realizing the movement of the measurement control point.

[0010] In some embodiments, the mounting platform has legs at its bottom, with rollers mounted on the bottom of the legs.

[0011] This technical solution, by setting up support legs, avoids making the mounting platform too large and reducing the overall weight while meeting the height requirements of the measurement control points. It also facilitates movement and saves on the manufacturing cost of the measurement platform.

[0012] In some embodiments, four legs are provided, with the four legs corresponding to the four corners of the mounting platform; each of the four legs is equipped with a roller.

[0013] This technical solution increases the support effect of the support legs on the mounting platform by setting support legs at the four corners of the mounting platform; by installing rollers on each support leg, not only can the movable measuring platform be facilitated, but also the tilting of the measuring platform during the movement can be prevented, ensuring the stability and reliability of the measuring platform during the movement process.

[0014] In some embodiments, a connector is also included, which is located below the mounting platform and faces all four legs; the connector is interconnected with all four legs.

[0015] This technical solution increases the overall stability of the measurement platform by using connectors to connect the four legs together.

[0016] In some embodiments, the bottom of the outrigger is provided with a connecting plate, and the connecting plate is equipped with a support member for raising the connecting plate so that the roller is at a certain height from the ground.

[0017] This technical solution uses a support structure to raise the connecting plate, thereby raising the rollers to a certain height above the ground. This prevents the measurement platform from moving and ensures the reliability and accuracy of the measurement control point settings.

[0018] In some embodiments, the periphery of the upper surface of the connecting plate extends beyond the bottom surface of the leg so that the middle portion of the connecting plate is connected to the bottom of the leg, the outer edge of the connecting plate is located on the outer periphery of the leg, wherein rollers are mounted on the middle portion of the connecting plate, and supports are located at the outer edge of the connecting plate.

[0019] This technical solution extends the upper surface of the connecting plate beyond the bottom surface of the support leg to facilitate the connection of the support member to the connecting plate.

[0020] In some embodiments, the four corners of the connecting plate are provided with support members.

[0021] This technical solution ensures the lifting effect of the support components on the connecting plate and guarantees the stability of the measuring platform after it is lifted by setting support components at the four corners of the connecting plate.

[0022] In some embodiments, the support includes a connecting rod and a locking nut. The connecting rod passes through the connecting plate and has external threads. The locking nut is located on the connecting rod and is positioned below the connecting plate, abutting against the connecting plate. Rotating the locking nut adjusts the position of the connecting rod below the connecting plate, thereby raising or lowering the connecting plate.

[0023] This technical solution designs the support component to include a connecting rod and a locking nut. By utilizing the cooperation between the locking nut and the connecting rod, the size of the connecting rod below the connecting plate can be adjusted, thereby raising and lowering the connecting plate, and thus realizing the raising and lowering of the measuring platform.

[0024] In some embodiments, the connecting rod is also provided with a limiting nut, which is located above the connecting plate and is used to prevent the connecting plate from detaching from the connecting rod.

[0025] This technical solution uses a limiting nut, which is positioned above the connecting plate, to prevent the connecting plate from detaching from the connecting rod.

[0026] In some embodiments, a measuring instrument is mounted on the centering plate, and a column is provided on the top of the mounting platform, with the centering plate located at the top of the column.

[0027] This technical solution increases the height of the forced centering plate by setting up a column, thus making it easier for surveyors to operate the measuring instruments while standing on the mounting platform.

[0028] Based on the above technical solution, the movable measuring platform in this utility model embodiment can drive the forced centering plate to move, so as to realize the movement of the measurement control point, thereby meeting the measurement and layout requirements under different construction conditions. Moreover, the overall structure of the movable measuring platform is simple and the manufacturing cost is low. Attached Figure Description

Therefore, a feature defined as "first," "second," or "third" may explicitly or implicitly include one or more of that feature.

[0038] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0039] As attached Figure 1 As shown in an illustrative embodiment of the movable measuring platform of this utility model, the movable measuring platform includes a mounting platform 3, a forced centering plate 1, and rollers 8; the mounting platform 3 is used to mount the forced centering plate 1; the forced centering plate 1 is disposed on the mounting platform 3; the forced centering plate 1 is used to form a measurement control point; the rollers 8 are disposed at the bottom of the mounting platform 3, and the rollers 8 are in contact with the ground to drive the mounting platform 3 and the forced centering plate 1 to move, thereby realizing the movement of the measurement control point.

[0040] like Figure 1As shown, the top of the mounting platform 3 is provided with a column 2, and the forced centering plate 1 is located at the upper end of the column 2. The column 2 is used to increase the setting height of the forced centering plate 1 so that the measuring instrument is located at the required height.

[0041] In some embodiments, a measuring instrument is installed on the centering plate 1. Placing the centering plate 1 on the upper end of the column 2 allows the observer to easily operate the measuring instrument while standing on the mounting platform 3.

[0042] The column 2 is preferably located at the center of the mounting platform 3 to ensure the overall stability of the movable measuring platform.

[0043] In some embodiments, the height of the column 2 is determined according to the height of the observer to facilitate the observer's operation of the measuring instrument.

[0044] The height of the column 2 is preferably 1.3 meters, and the diameter of the column 2 is preferably 120 mm, so that the column 2 has high strength.

[0045] In some embodiments, the mounting platform 3 is made of steel plate, and the thickness of the mounting platform 3 is preferably 1 cm to ensure the strength of the mounting platform 3. The length and width of the mounting platform 3 are preferably 1 meter.

[0046] like Figure 1 As shown, a safety railing 4 is provided around the outer perimeter of the mounting platform 3 to protect the observers and prevent them from falling off the mounting platform 3.

[0047] It should be noted that the height of column 2 is higher than the height of safety railing 4, so as to avoid the safety railing 4 from obstructing the center plate 1 or measuring instruments and affecting the observation effect.

[0048] like Figure 1 As shown, the bottom of the mounting platform 3 is equipped with support legs 5, and rollers 8 are installed at the bottom of the support legs 5. Since the measurement control points need to be at a certain height from the ground, the overall height of the measurement platform is usually relatively high. Setting support legs 5 can avoid making the height of the mounting platform 3 too large while meeting the height requirements of the measuring instrument. This not only reduces the overall weight of the measurement platform and facilitates movement, but also saves on the manufacturing cost of the measurement platform.

[0049] In some embodiments, four support legs 5 are provided, with the four support legs 5 corresponding to the four corners of the mounting platform 3; each of the four support legs 5 is equipped with a roller 8. By providing support legs 5 at the four corners of the mounting platform 3, the supporting effect of the support legs 5 on the mounting platform 3 is increased; by installing rollers 8 on each support leg 5, not only can the movable measuring platform be facilitated, but also the tilting of the measuring platform during movement can be prevented, ensuring the stability and reliability of the measuring platform during movement.

[0050] It should be noted that the height of the outrigger 5 is determined according to the on-site construction conditions. Usually, the height of the four outriggers 5 is the same to keep the mounting platform 3 level, thereby ensuring the accuracy of the horizontal setting of the forced centering plate 1 or measuring instruments.

[0051] In some embodiments, the diameter of the support leg 5 is 150 mm to give the support leg 5 good strength, thereby increasing the support effect of the support leg 5 on the platform.

[0052] like Figure 1 As shown, the aforementioned movable measuring platform also includes a connector 6, which is located below the mounting platform 3 and faces the four legs 5. The connector 6 is connected to the four legs 5 to connect the four legs 5 into one unit, thereby increasing the overall stability of the measuring platform.

[0053] It should be noted that the size of the connector 6 is determined based on the spacing between the legs 5, and the diameter of the connector 6 is preferably 80cm.

[0054] like Figure 1 As shown, the bottom of the support leg 5 is provided with a connecting plate 7, and the connecting plate 7 is equipped with a support member 9. The support member 9 is used to raise the connecting plate 7 so that the roller 8 is located above the ground, so that the roller 8 is a certain height above the ground, thereby preventing the measuring platform from moving, avoiding the measurement control point from moving arbitrarily, and ensuring the reliability of the setting position of the measurement control point.

[0055] To facilitate the installation of the support member 9, the upper surface of the connecting plate 7 extends beyond the bottom surface of the support leg 5, so that the middle part of the connecting plate 7 is connected to the bottom of the support leg 5, the outer edge of the connecting plate 7 is located on the outer periphery of the support leg 5, wherein the roller 8 is installed in the middle part of the connecting plate 7, and the support member 9 is located at the outer edge of the connecting plate 7.

[0056] In some embodiments, the connecting plate 7 is made of steel plate, and the thickness of the connecting plate 7 is preferably 1 cm.

[0057] like Figure 1 As shown, the four corners of the connecting plate 7 are respectively provided with support members 9 to ensure the lifting effect of the support members 9 on the connecting plate 7 and to ensure the stability of the measuring platform after it is lifted.

[0058] It should be noted that since each connecting plate 7 is provided with four support members 9, and the four support members 9 are set independently and the height of the connecting plate 7 can be adjusted individually, when the ground of the construction site is uneven, the support members 9 can be adjusted to keep the mounting platform 3 level.

[0059] like Figure 2As shown, the support member 9 includes a connecting rod 93 and a locking nut 92. The connecting rod 93 passes through the connecting plate 7 and has an external thread. The locking nut 92 is located on the connecting rod 93 and is positioned below the connecting plate 7, abutting against the connecting plate 7. Rotating the locking nut 92 can adjust the position of the connecting rod 93 below the connecting plate 7, thereby raising or lowering the connecting plate 7.

[0060] It should be noted that when the support member 9 raises the connecting plate 7, the connecting rod 93 supports the connecting plate 7 so that the roller 8 is a certain distance from the ground, thereby preventing the roller 8 from contacting the ground and rolling.

[0061] When it is necessary to raise the connecting plate 7 to prevent the roller 8 from contacting the ground, tighten the locking nut 92 to increase the dimension of the connecting rod 93 below the connecting plate 7, thereby increasing the height of the connecting plate 7; when it is necessary to lower the height of the connecting plate 7 so that the roller 8 contacts the ground, tighten the locking nut 92 in the opposite direction to reduce the dimension of the connecting rod 93 below the connecting plate 7, thereby reducing the height of the connecting plate 7.

[0062] It should be noted that when the roller 8 contacts the ground, the height of the connecting plate 7 is reduced to its lowest point. Under the support of the roller 8 on the connecting plate 7, even if the locking nut 92 is tightened further, the height of the connecting plate 7 cannot be reduced.

[0063] In some embodiments, the lower end of the connecting rod 93 is provided with a pad to increase the contact area between the connecting rod 93 and the ground, thereby increasing the support effect of the ground on the connecting rod 93, and further increasing the support effect of the connecting rod 93 on the movable measuring platform.

[0064] like Figure 2 As shown, a limiting nut 91 is also provided on the connecting rod 93. The limiting nut 91 is located above the connecting plate 7. The limiting nut 91 is used to prevent the connecting plate 7 from detaching from the connecting rod 93, preventing the connecting plate 7 from moving upward and detaching from the connecting rod 93, and ensuring the supporting effect of the support member 9 on the connecting plate 7 and the measuring platform. The above-mentioned movable measuring platform is used as follows: after the roller 8 contacts the ground and the measuring platform is moved to the designated position, the locking nut 92 is rotated to raise the connecting rod 93 and the connecting plate 7, so that the roller 8 is a certain height above the ground. The observer stands on the mounting platform 3 and installs the measuring instrument on the forced centering plate 1, so that the measuring instrument can perform measurement and layout.

[0065] In some embodiments, the measuring instrument is a total station. After the total station is installed on the forced centering plate 1, the foot screws are adjusted until the electronic bubble is centered. Orientation is performed by resection. Once orientation is completed, measurement and layout can be carried out.

[0066] It should be noted that the measuring instrument can be a total station or other instruments. The measuring instrument is existing technology in this field and will not be described in detail here.

[0067] The aforementioned mobile measuring platform uses a forced centering plate 1 above the mounting platform 3 to form a measurement control point, and rollers 8 at the bottom of the mounting platform 3 to move the mounting platform 3. This not only moves the measurement control point to meet the measurement and layout requirements under different construction conditions, but also the mobile measuring platform has a simple overall structure and low manufacturing cost.

[0068] Finally, it should be noted that the various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.

[0069] The above embodiments are only used to illustrate the technical solution of this utility model and not to limit it; although the utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications can still be made to the specific implementation of this utility model or equivalent substitutions can be made to some technical features without departing from the spirit of the technical solution of this utility model, and all such modifications and substitutions should be covered within the scope of the technical solution claimed by this utility model.
