Description

Technical Field

[0001] This utility model relates to the field of surveying support, and in particular to a portable surveying support that can be quickly deployed for cadastral surveying. Background Technology

[0002] Cadastral surveying is a crucial foundation for land management. Through professional surveying techniques and methods, it accurately determines elements such as land ownership boundaries, location, shape, and area, providing accurate and reliable data support for land registration, certification, and the rational planning, utilization, and management of land resources. In cadastral surveying, surveying supports are an indispensable key piece of equipment.

[0003] A portable surveying device, disclosed in CN223063602U, includes a support and a surveying instrument. The support includes several legs and a support base. The legs are connected to the support base via a connecting component. The legs can be adjusted and folded together during storage by using telescopic and connecting components to retract the first and second support rods, reducing the storage volume. However, the legs are fixed by multiple bolts in the connecting component, requiring manual tightening or loosening of each bolt to rotate, unfold, and lock the legs. This operation is cumbersome and makes it difficult to quickly unfold and retract, affecting measurement efficiency.

[0004] Therefore, there is a need to design a portable surveying bracket for cadastral surveying that can be quickly unlocked and deployed to support the device during use, and can be folded and locked after use by rotating the support rod. This bracket is simple to operate, easy to carry and store, and improves measurement efficiency. Utility Model Content

[0005] To overcome the shortcomings of the current device, which uses multiple bolts in the connecting assembly to fix the legs, requiring manual tightening or loosening of each bolt to rotate, unfold, and lock the legs, making operation cumbersome and difficult to achieve rapid unfolding and folding, thus affecting measurement efficiency, this utility model provides a portable surveying support for cadastral surveying that can quickly unlock and unfold the support rod for use, and after use, rotate the support rod to fold and lock the device for storage. It is simple to operate, easy to carry and store, and improves measurement efficiency.

[0006] The technical solution of this utility model is: a portable surveying support for cadastral surveying that can be quickly deployed, comprising a mounting frame, a rotating base, a support rod, an extension rod, a threaded sleeve, a support tip, a limiting component, and an adjusting component. Multiple rotating bases are rotatably connected to the mounting frame, and a support rod is connected to each rotating base. A threaded sleeve is rotatably connected to the lower part of each support rod, and an extension rod is threadedly connected to each threaded sleeve. A support tip is connected to the lower side of each extension rod. A limiting component for limiting and locking the support rod is provided between the mounting frame and the rotating base. An adjusting component for installing and adjusting the position of surveying instruments is provided on the upper part of the mounting frame.

[0007] Furthermore, the rotating seats are evenly distributed around the circumference of the mounting frame.

[0008] Furthermore, all the support tips are conical.

[0009] Furthermore, the limiting component includes a connecting block, a clamping frame, a torsion spring, a fixed seat, a limiting block, and a blocking block. The connecting block is connected to the lower side of the mounting frame, and multiple fixed seats are connected to the connecting block. Each fixed seat is rotatably connected to a clamping frame, and each clamping frame is connected to an adjacent fixed seat by a torsion spring. Each rotating seat is also connected to the mounting frame by two torsion springs. Each rotating seat is connected to two integrally formed limiting blocks on its upper part. Multiple blocking blocks are connected to the upper side of the mounting frame, and each limiting block is in contact with an adjacent blocking block.

[0010] Furthermore, the adjustment assembly includes a threaded telescopic rod, a surveyor mounting plate, and a threaded sleeve. The threaded sleeve is rotatably connected to the upper part of the mounting frame, and the threaded telescopic rod is threadedly connected to the threaded sleeve. The surveyor mounting plate is connected to the upper part of the threaded telescopic rod.

[0011] Furthermore, it also includes a throttle, with the throttle connected to the upper part of the threaded sleeve.

[0012] This utility model has the following advantages: 1. This utility model can quickly unfold by rotating the support rod and disengaging from the clamping frame. After being limited by the limiting block, the measuring instrument is installed for measurement. Then, the threaded telescopic rod is retracted, and the support rod is rotated to reset and lock into the clamping frame. Then the extension rod is retracted, so that the support rod can be quickly unlocked and unfolded for support and use. After use, the support rod can be rotated to retract and lock, and the device can be folded and stored. The operation is simple, easy to carry and store, and improves measurement efficiency.

[0013] 2. This utility model adjusts the position of the support tip by moving the extension rod, then installs the surveyor on the surveyor mounting plate, and then adjusts the height of the surveyor by moving the threaded telescopic rod. This allows for adjustment of the position of the support tip and the height of the surveyor for cadastral surveying, ensuring that the surveyor is in the best observation position, reducing errors, and making it easy to adapt to different terrains for surveying. It is flexible and convenient to use. Attached Figure Description

Detailed Implementation

[0019] The preferred technical solution of this utility model will be described in detail below with reference to the accompanying drawings.

[0020] A portable, rapidly deployable surveying scaffold for cadastral surveying, such as... Figures 1-4 As shown, the system includes a mounting frame 1, rotating seats 2, support rods 3, extension rods 4, threaded sleeves 5, support tips 6, a limiting component, and an adjusting component. Three rotating seats 2 are rotatably connected to the mounting frame 1, and the rotating seats 2 are evenly distributed around the circumference of the mounting frame 1. Each rotating seat 2 is connected to a support rod 3, and each support rod 3 is rotatably connected to a threaded sleeve 5. Each threaded sleeve 5 is connected to an extension rod 4 via a thread. Each extension rod 4 has a support tip 6 connected to its lower side. The support tips 6 are all conical, facilitating insertion into the ground for fixation. A limiting component is provided between the mounting frame 1 and the rotating seats 2 for limiting and locking the support rods 3. An adjusting component is provided on the upper part of the mounting frame 1 for installing and adjusting the position of surveying instruments.

[0021] like Figure 2 , Figure 3 and Figure 4 As shown, the limiting assembly includes a connecting block 7, a clamping frame 8, a torsion spring 9, a fixed seat 10, a limiting block 15, and a blocking block 16. The mounting frame 1 is connected to the lower side of the connecting block 7, and six fixed seats 10 are connected to the connecting block 7. Each fixed seat 10 is rotatably connected to a clamping frame 8, and each clamping frame 8 is connected to an adjacent fixed seat 10 with a torsion spring 9. Each rotating seat 2 is also connected to the mounting frame 1 with two torsion springs 9. Each rotating seat 2 is connected to two integrally formed limiting blocks 15. The mounting frame 1 is connected to the upper side with three blocking blocks 16, and each limiting block 15 is in contact with an adjacent blocking block 16.

[0022] like Figure 1 , Figure 2 and Figure 4 As shown, the adjustment assembly includes a threaded telescopic rod 11, a surveying instrument mounting plate 12, and a threaded sleeve 13. The threaded sleeve 13 is rotatably connected to the upper part of the mounting bracket 1, and the threaded telescopic rod 11 is threadedly connected to the threaded sleeve 13. The surveying instrument mounting plate 12 is connected to the upper part of the threaded telescopic rod 11. It also includes a throttle 14, which is connected to the upper part of the threaded sleeve 13, making it easy to grip and rotate the threaded sleeve 13.

[0023] When cadastral surveying requires support for surveying equipment, this device can be used. The device is lifted and moved to a suitable area using the throttle 14. At this time, the torsion spring 9 on the mounting frame 1 is in a deformed state. Then, the screw sleeve 5 is rotated, causing the extension rod 4 to move under the action of the thread, which in turn moves the support tip 6. The support tips 6 are all tapered. After adjusting to the appropriate position, the support rod 3 is pulled to rotate and compress the clamping frame 8, causing it to rotate along the fixed base 10. The corresponding torsion spring 9 deforms. When the support rod 3 disengages from the clamping frame 8, the corresponding torsion spring 9 rotates back to its original position. The clamping frame 8 rotates in the opposite direction to reset, causing the rotating base 2 to rotate along the mounting frame 1. The torsion spring 9 on the mounting frame 1 rotates back to its original position, causing the rotating base 2 to rotate and unfold rapidly, thus allowing the support rod 3 and extension rod 4 to move. The support tip 6 unfolds quickly, causing the limiting block 15 to rotate and contact the blocking block 16 for limiting. The rotating seat 2 is evenly distributed around the circumference of the mounting frame 1. Then, the support tip 6 is inserted into the ground to fix the device. Next, according to the surveying requirements, the surveyor is installed on the surveyor mounting plate 12. Then, the threaded sleeve 13 is rotated by the throttle 14. Under the action of the thread, the threaded telescopic rod 11 moves, which drives the surveyor mounting plate 12 to move, thus moving the surveyor and adjusting the height of the surveyor. Then, the surveyor is used to conduct cadastral surveys. This allows for adjustment of the position of the support tip 6 and the height of the surveyor for cadastral surveys, ensuring that the surveyor is in the best observation position, reducing errors, and facilitating surveying in different terrains. It is flexible and convenient to use.

[0024] After the test is completed, remove the measuring instrument and then rotate the threaded sleeve 13 in the opposite direction. Under the action of the thread, the threaded telescopic rod 11 and the measuring instrument mounting plate 12 move in opposite directions and retract. Then lift the device so that the support tip 6 is separated from the ground. Then rotate the support rod 3 in the opposite direction to squeeze the clamping frame 8 to rotate and open. The corresponding torsion spring 9 deforms. When the support rod 3 is inserted between the clamping frames 8, the corresponding torsion spring 9 rotates back to its original position. The clamping frame 8 rotates back to lock the support rod 3, which in turn causes the rotating seat 2 to rotate and retract. The torsion spring 9 on the mounting frame 1 deforms. At the same time, the limit block 15 rotates in the opposite direction and disengages from the blocking block 16. Then rotate the threaded sleeve 5 in the opposite direction. Under the action of the thread, the extension rod 4 moves and retracts, which in turn drives the support tip 6 to move. This allows for quick unlocking and unfolding of the support rod 3 for support and use. After use, the support rod 3 can be rotated to retract and lock, and the device can be folded and stored. The operation is simple, easy to carry and store, and improves measurement efficiency. Then, the device can be taken away.
