Description

Technical Field

[0001] This utility model relates to the field of support adjustment technology, specifically a surveying support leveling mechanism. Background Technology

[0002] In surveying engineering practice, the stability and leveling accuracy of measuring instruments are core elements for ensuring the quality of spatial data acquisition. Traditional surveying scaffolding leveling systems generally use manual adjustment, achieving horizontal calibration of the equipment platform by adjusting the telescopic legs of the tripod or the threaded adjustment device on the spherical support. However, the force-bearing area of ​​the tripod legs within the leveling mechanism is mostly fixed, lacking adaptive grounding design, making it difficult to dynamically adjust the support force distribution according to surface hardness or slope, thus reducing the flexibility of the surveying scaffolding. Utility Model Content

[0003] The purpose of this utility model is to provide a leveling mechanism for a surveying support to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a leveling mechanism for a surveying support frame, comprising a support frame, three positioning rods fixedly connected to the support frame, support feet rotatably connected to the outer surfaces of the positioning rods, a movable sleeve plate slidably connected to the support frame, three connecting plates rotatably connected to the movable sleeve plate, an auxiliary plate above the support feet, an adsorption plate one and an adsorption plate two slidably connected above the auxiliary plate, an adjustment structure inside the auxiliary plate, the adjustment structure being connected to adsorption plate one and adsorption plate two, a snap-fit ​​structure outside the support feet, the snap-fit ​​structure being connected to the auxiliary plate, the adjustment structure comprising a first threaded rod, a second threaded rod, and a motor, a slider one being threadedly connected to the outer surface of the first threaded rod, and a slider two being threadedly connected to the outer surface of the second threaded rod.

[0005] As a further preferred embodiment of this technical solution, the top of the movable sleeve is provided with a locking nut, the movable sleeve is connected to the support foot through a connecting plate, and the second adsorption plate is slidably connected inside the first adsorption plate.

[0006] As a further preferred embodiment of this technical solution, the first threaded rod is rotatably connected to one side of the auxiliary plate, the second threaded rod is rotatably connected to the other side of the auxiliary plate, and the motor is fixedly connected inside the auxiliary plate.

[0007] As a further preferred embodiment of this technical solution, the first slider is fixedly connected to the lower part of the second adsorption plate, the second slider is fixedly connected to the lower part of the first adsorption plate, and the first slider is slidably connected inside the auxiliary plate.

[0008] As a further preferred embodiment of this technical solution, the second slider is slidably connected within the auxiliary plate, the second bevel gear meshes with the first bevel gear, and the third bevel gear meshes with the first bevel gear.

[0009] As a further preferred embodiment of this technical solution, the snap-fit ​​structure includes a concave plate and a convex plate.

[0011] This utility model provides a leveling mechanism for a surveying support, which has the following advantages:

[0012] (1) This utility model sets up an auxiliary plate, an adjustment structure, an adsorption plate one and an adsorption plate two, and drives a bevel gear one to rotate through a motor. Since bevel gear one meshes with bevel gear two and bevel gear three, the first threaded rod and the second threaded rod will rotate synchronously in opposite directions. Adsorption plate one and adsorption plate two will move relative to each other above the auxiliary plate. The leveling mechanism, through the cooperation between bevel gear one, bevel gear two and bevel gear three, allows adsorption plate one and adsorption plate two to be positioned on the surface of the auxiliary plate, which is convenient to adjust the force-bearing area according to the actual situation, thereby ensuring the flexibility of the surveying support. By adjusting the position of the adsorption plate, the force-bearing area can be increased, the pressure on the ground can be reduced, the stability of the support can be enhanced, and the risk of settlement and tilting can be reduced.

[0013] (2) By setting a snap-fit ​​structure, the auxiliary plate is snapped into the support foot through the convex plate, which drives the limiting plate to slide on the surface of the column. When the column rotates around the guide rod and snaps into the convex plate, the reset limiting plate will snap into the convex plate, so that the auxiliary plate and the support foot can achieve the function of quick assembly, and the auxiliary plate can be easily replaced or repaired in the future.

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0020] This utility model provides a technical solution: such as Figure 1 and Figure 4 As shown in this embodiment, a surveying support leveling mechanism includes a support frame 1. The support frame 1 is fixedly connected to three positioning rods 2. Support feet 3 are rotatably connected to the outer surface of the positioning rods 2. A movable sleeve 4 is slidably connected to the outside of the support frame 1. Three connecting plates 6 are rotatably connected to the outside of the movable sleeve 4. An auxiliary plate 7 is provided above the support feet 3. An adsorption plate 10 and an adsorption plate 2 11 are slidably connected above the auxiliary plate 7. An adjustment structure 8 is provided inside the auxiliary plate 7. The adjustment structure 8 is connected to the adsorption plate 10 and the adsorption plate 2 11. A snap-fit ​​structure 9 is provided outside the support feet 3. The snap-fit ​​structure 9 is connected to the auxiliary plate 7. The adjustment structure 8 includes a first threaded rod 801, a second threaded rod 802, and a motor 803. A slider 1 807 is threadedly connected to the outer surface of the first threaded rod 801. A slider 2 808 is threadedly connected to the outer surface of the second threaded rod 802. One end of the second threaded rod 802 is connected to a second bevel gear 805, one end of the first threaded rod 801 is connected to a third bevel gear 806, and the output shaft of the motor 803 is connected to a first bevel gear 804.

[0021] like Figure 1 and Figure 3As shown, the top of the movable sleeve 4 is provided with a locking nut 5. The movable sleeve 4 is connected to the support foot 3 through the connecting plate 6. The second adsorption plate 11 is slidably connected inside the first adsorption plate 10. The first threaded rod 801 is rotatably connected to one side of the auxiliary plate 7, and the second threaded rod 802 is rotatably connected to the other side of the auxiliary plate 7. The motor 803 is fixedly connected inside the auxiliary plate 7. The first slider 807 is fixedly connected below the second adsorption plate 11, and the second slider 808 is fixedly connected below the first adsorption plate 10. The first slider 807 is slidably connected inside the auxiliary plate 7, and the second slider 808 is slidably connected inside the auxiliary plate 7. The second bevel gear 805 meshes with the first bevel gear 804, and the third bevel gear 806 meshes with the first bevel gear 804.

[0022] By setting the auxiliary plate 7, when the first threaded rod 801 and the second threaded rod 802 rotate synchronously in opposite directions within the auxiliary plate 7, the first adsorption plate 10 and the second adsorption plate 11 will slide within the auxiliary plate 7 under the action of the second slider 808 and the first slider 807. This allows the auxiliary plate 7 to play a certain guiding role in the movement of the first adsorption plate 10 and the second adsorption plate 11, preventing the first adsorption plate 10 and the second adsorption plate 11 from shifting their positions during movement.

[0023] like Figure 4 As shown, the snap-fit ​​structure 9 includes a concave plate 901 and a convex plate 902. The convex plate 902 is fixedly connected to the bottom of the auxiliary plate 7 and snaps into the support foot 3. The concave plate 901 is fixedly connected to the outside of the support foot 3. A guide rod 903 is rotatably connected inside the concave plate 901. A column 904 is fixedly connected to the outside of the guide rod 903. A limit plate 905 is slidably connected to the outside of the column 904. The limit plate 905 is snapped into the inside of the convex plate 902. A spring 906 is sleeved on the column 904. The limit plate 905 is connected to the column 904 through the spring 906.

[0024] By setting a spring 906, the limiting plate 905 is driven to slide on the surface of the column 904. When the limiting plate 905 moves, it will cause the spring 906 to deform, so that the spring 906 provides a certain support for the movement of the column 904. When the limiting plate 905 loses resistance, it will be reset by the spring 906, so as to prevent the limiting plate 905 from loosening when it is engaged with the convex plate 902.

[0025] This utility model provides a leveling mechanism for a surveying support, the specific working principle of which is as follows:

[0026] When the support frame 1 is in use, the auxiliary plate 7 can be snapped into the support foot 3 through the convex plate 902, and then the limiting plate 905 can slide on the surface of the column 904. When the limiting plate 905 moves, it will cause the spring 906 to deform. When the column 904 rotates around the guide rod 903 and is snapped into the convex plate 902, the limiting plate 905 will be reset by the spring 906 after being released. After being reset, the limiting plate 905 will be snapped into the convex plate 902.

[0027] When the movable sleeve 4 moves on the surface of the support frame 1, the movable sleeve 4 will drive the support foot 3 to rotate around the positioning rod 2 via the connecting plate 6. When the position of the support foot 3 is adjusted, the position of the movable sleeve 4 is locked by the locking nut 5. When it is necessary to adjust the force-bearing area of ​​the support foot 3, the motor 803 drives the bevel gear 1 804 to rotate. Since the bevel gear 1 804 meshes with the bevel gear 2 805 and the bevel gear 1 804 meshes with the bevel gear 3 806, the first threaded rod 801 and the second threaded rod 802 will rotate synchronously in opposite directions, while the adsorption plate 1 10 and the adsorption plate 2 11 will move relative to each other above the auxiliary plate 7.

[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
