Description

Technical Field

[0001] This invention relates to the field of surveying and mapping technology, and in particular to a surveying instrument support that can automatically level itself. Background Technology

[0002] A surveying instrument stand is a device specifically designed to support and stabilize various surveying instruments, ensuring that the instruments remain level and stable during surveying operations, thereby guaranteeing the accuracy of data acquisition. These stands are typically used to support precision surveying equipment such as total stations, theodolites, levels, and GNSS receivers.

[0003] For example, a surveying instrument support device with automatic leveling function, with publication (announcement) number CN215000477U, relates to the field of safety support technology. The device includes a triangular mounting plate with three hinged support legs. Each side of the triangular mounting plate is connected to two cylinders. The output ends of the two adjacent cylinders at the apex of the triangular mounting plate are hinged to a first connecting rod and a second connecting rod, respectively. The first and second connecting rods are hinged to a third and a fourth connecting rod, respectively. A first connecting block is rotatably connected to the hinge axis of the third and fourth connecting rods. A support rod is hinged to the first connecting block, and a support plate is hinged to the support rod via a second connecting block. An instrument connecting seat is located at the top of the support plate, and an electronic leveling instrument and a controller are located at the bottom of the support plate. The controller is electrically connected to the cylinders and the electronic leveling instrument, respectively. This allows the support plate to be leveled, ensuring it is horizontal during use. This reduces the tediousness of manual leveling by surveyors, saving time and effort, and further improving measurement accuracy. Although the device can achieve automatic leveling, the surveying instrument needs to be fixed by bolting the arc-shaped plate during installation, which is inconvenient for quick assembly and disassembly.

[0004] Therefore, it is necessary to design a surveying instrument support that can automatically level, is easy to assemble and disassemble, and is simple to operate and convenient to use. Summary of the Invention

[0005] To overcome the shortcomings of existing surveying instrument brackets, which require bolts to lock the arc plate to fix the surveying instrument during installation, making quick assembly and disassembly inconvenient, this invention provides a surveying instrument bracket that can automatically level, facilitates the assembly and disassembly of the surveying instrument, and is simple to operate and convenient to use.

[0006] The technical solution is as follows: A surveying instrument support with automatic leveling includes a support frame, guide blocks, locking knobs, lifting rods, a support plate, a leveling component, and a surveying component. Multiple support frames are rotatably connected to the lower part of the support plate. Guide blocks are slidably connected to the upper part of each support frame. Locking knobs are threadedly connected to each guide block. Each locking knob contacts an adjacent support frame. Lifting rods are connected to the lower side of each guide block. A leveling component capable of automatic leveling is provided on the support plate. A surveying component that can be easily loaded and unloaded is provided on the leveling component.

[0007] As a preferred option, the locking knob is provided with anti-slip texture.

[0008] Preferably, the lower part of the lifting rod is tapered.

[0009] Preferably, the leveling assembly includes a connecting frame, a cylinder, a ball joint, a telescopic rod, and a connecting plate. Two connecting frames are connected to the lower side of the support plate, and a cylinder is connected to each connecting frame. The cylinder and the processor are electrically connected through a control module. Two telescopic rods are connected to the support plate. The telescopic ends of the telescopic rods are rotatably connected to the connecting plate through a ball joint. The telescopic ends of the cylinders are also rotatably connected to the connecting plate through a ball joint.

[0010] Preferably, the system also includes a surveying component, which includes a pull rod, a rotating disk, insert blocks, a torsion spring, an inclination sensor, a surveying instrument, and locking blocks. The rotating disk is rotatably connected inside the connecting disk, a pull rod is connected to the front of the rotating disk, multiple insert blocks are connected to the outside of the rotating disk, a torsion spring is connected between the rotating disk and the connecting disk, an inclination sensor is connected to the middle of the rotating disk, and the inclination sensor is electrically connected to a cylinder. The surveying instrument is located above the connecting disk, and multiple locking blocks are connected to the lower side of the surveying instrument, with each insert block engaging with an adjacent locking block.

[0011] Preferably, the upper side of the insert is slanted.

[0012] The beneficial effects of this invention are as follows: Based on the detection of the tilt sensor, the cylinder corresponding to the tilt position is activated, and the connecting plate is tilted and rotated through the ball joint. The pull rod is pushed to the right, which drives the rotating plate to rotate. The torsion spring is deformed, so that the insert block is no longer locked with the locking block. Then the surveying instrument is moved upward and taken out. This achieves the effect of automatic leveling, convenient disassembly and assembly of the surveying instrument, simple operation and convenient use. Attached Figure Description

Detailed Implementation

[0019] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0020] A self-leveling surveying instrument stand, such as Figure 1 As shown, it includes a support frame 1, guide block 2, locking knob 3, lifting rod 4, support plate 5, leveling component, and surveying component. The lower part of the support plate 5 is rotatably connected to three support frames 1. The upper part of each support frame 1 is slidably connected to a guide block 2. Each guide block 2 is threadedly connected to a locking knob 3. The locking knob 3 has anti-slip texture for easy gripping. Each locking knob 3 is in contact with the adjacent support frame 1. The lower side of each guide block 2 is connected to a lifting rod 4. The lower part of each lifting rod 4 has a conical structure for easy insertion into the ground for fixation. The support plate 5 is equipped with a leveling component, and the leveling component is equipped with a surveying component.

[0021] like Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, the leveling assembly includes a connecting frame 6, a cylinder 7, a ball joint 8, a telescopic rod 9, and a connecting plate 10. Two connecting frames 6 are connected to the lower side of the support plate 5, and a cylinder 7 is connected to each connecting frame 6. The cylinder 7 and the processor are electrically connected through a control module. Two telescopic rods 9 are connected to the support plate 5. The telescopic ends of the telescopic rods 9 are rotatably connected to the connecting plate 10 through a ball joint 8. The telescopic ends of the cylinders 7 are also rotatably connected to the connecting plate 10 through a ball joint 8.

[0022] like Figures 2-5As shown, it also includes a surveying component, which includes a pull rod 11, a rotating disk 12, insert blocks 13, a torsion spring 14, an inclination sensor 15, a surveying instrument 16, and a locking block 17. The rotating disk 12 is rotatably connected inside the connecting disk 10. The pull rod 11 is connected to the front of the rotating disk 12. Three insert blocks 13 are connected to the outside of the rotating disk 12. The upper side of each insert block 13 is inclined to facilitate being squeezed and moved. A torsion spring 14 is connected between the rotating disk 12 and the connecting disk 10. An inclination sensor 15 is connected to the middle of the rotating disk 12. The inclination sensor 15 is electrically connected to the cylinder 7. The surveying instrument 16 is located above the connecting disk 10. Three locking blocks 17 are connected to the lower side of the surveying instrument 16. Each insert block 13 is engaged with an adjacent locking block 17.

[0023] When using this invention, first place the support frame 1 in the surveying area, then rotate and unfold the support frame 1, then rotate and loosen the locking knob 3, then move the guide block 2 downward, causing the lifting rod 4 to move downward and extend, adjusting its height. After adjustment, rotate and tighten the knob, then insert the lifting rod 4 into the ground. After installation, insert the locking block 17 on the surveying instrument 16 into the connecting plate 10, so that the locking block 17 presses the insert block 13, causing the rotating plate 12 to rotate, and the torsion spring 14 to deform. When the locking block 17 is fully inserted into the connecting plate 10, the torsion spring 14 returns to its original state, causing the connecting plate 10 to rotate and reset, so that the insert block 13 and the locking block 17 are engaged, completing the installation of this device.

[0024] After installation, the tilt angle of the connecting plate 10 is detected by the tilt sensor 15. Based on the detection of the tilt sensor 15, the cylinder 7 corresponding to the tilt position is activated, and the connecting plate 10 is tilted and rotated through the ball joint 8, causing the telescopic rod 9 to extend and retract. When it is necessary to disassemble the surveying instrument 16, the pull rod 11 can be moved to the right to drive the rotating plate 12 to rotate. The torsion spring 14 deforms, so that the insert block 13 is no longer engaged with the locking block 17. Then the surveying instrument 16 can be moved upward and removed, thereby achieving automatic leveling and facilitating the disassembly and assembly of the surveying instrument 16. The operation is simple and convenient.
