Technical Field

[0001] This utility model relates to the technical field, and in particular to an adjustable height building surveying benchmark. Background Technology

[0002] Building surveying beacons are a common auxiliary tool used in building engineering and surveying work. They are mainly used for elevation transfer, distance measurement, centering and positioning, and as observation targets.

[0003] Patent CN213902379U discloses a new type of marker for building surveying, including a first support rod, a second support rod, a main rod, and a limiting base plate. The bottom end of the main rod is fixed with a base, and each of the four corners of the bottom end of the base is fixed with an adjustment groove, and an adjustment block is installed inside the adjustment groove. When using this patent, the device is assembled and placed on the ground for marking. However, in the above-mentioned existing patent, when there is a large height difference between the measuring station and the target point, it is necessary to manually raise or dig the ground to adjust the height of the marker.

[0004] Therefore, there is a need to provide an adjustable-height building surveying benchmark. Utility Model Content

[0005] To overcome the shortcomings of existing patents where a large height difference exists between the measuring station and the target point, requiring manual elevation or ground excavation to adjust the height of the marker, this utility model provides an adjustable-height building measuring marker. This marker utilizes components such as a first sleeve, a second sleeve, and a third sleeve to adjust its height.

[0006] To address the aforementioned issues, this utility model employs the following technical solution: an adjustable-height building surveying pole, comprising a support plate, support frames, a support plate, and support rods. Three support frames are fixedly connected to the support plate, and a support plate is fixedly connected between the three support frames. Three support rods are hingedly mounted on the support plate. The pole also includes a first sleeve, a second sleeve, a third sleeve, a first screw, a ring, a threaded sleeve, a mounting plate, a signal receiver, and a distance sensor. The first sleeve is fixedly connected to the support plate. A second sleeve slides within the first sleeve, and a third sleeve slides within the second sleeve. A first screw is rotatably mounted on the support plate. The second sleeve is threadedly connected to the first screw. A ring rotatably mounts within the second sleeve. A threaded sleeve is fixedly connected to the ring and threadedly connected to the third sleeve, with the threaded sleeve sliding on the first screw. A mounting plate is fixedly connected to the third sleeve, and a signal receiver is mounted on the mounting plate. A distance sensor is mounted on the support plate.

[0007] As a preferred technical solution of this utility model, it also includes a second screw, a guide sleeve and connecting rods. The second screw is rotatably arranged on the support plate, the guide sleeve is threaded on the second screw, and three connecting rods are hinged on the guide sleeve.

[0008] As a preferred technical solution of this utility model, it also includes a connecting plate and a fixing nail. The connecting plate is fixedly connected to the support rod, and the fixing nail is threaded on the connecting plate.

[0009] As a preferred embodiment of this utility model, it also includes a rubber sleeve, with the support rod fitted with a rubber sleeve.

[0010] As a preferred technical solution of this utility model, it also includes a handwheel, with a handwheel fixedly connected to both the first screw and the second screw.

[0011] As a preferred technical solution of this utility model, it also includes a bubble level, with three bubble levels arranged on the tray.

[0012] Compared with the prior art, the present invention has the following technical effects: 1. By rotating the first screw with a handwheel, the first screw drives the second sleeve, the ring and the threaded sleeve to move upward along the first sleeve. The first screw drives the threaded sleeve to rotate, and the threaded sleeve drives the third sleeve to move upward, thereby adjusting the height of the signal receiver. The current height can be obtained from the transmission distance. There is a large height difference between the measuring station and the target point.

[0013] 2. By rotating the second screw through the handwheel, the second screw drives the guide sleeve to move, and the guide sleeve drives the three connecting rods to rotate, causing the connecting rods to squeeze the support rods outward. This allows the three support rods to be opened quickly, thus enabling them to adapt to uneven terrain and significantly improve the stability of the marker by increasing the support span.

Detailed Implementation

[0021] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments, but this does not limit the scope of protection and application of the present invention.

[0022] Example 1: An adjustable-height building surveying benchmark, see reference. Figures 1-6As shown, the system includes a support plate 1, a support frame 2, a support plate 3, and support rods 4. Three support frames 2 are evenly spaced on the top of the support plate 1 and welded together. A support plate 3 is welded between the tops of the three support frames 2. Three support rods 4 are evenly spaced and hinged on the support plate 1. The system also includes a first sleeve 5, a second sleeve 6, a third sleeve 7, a first screw 8, a ring 9, a threaded sleeve 10, a mounting plate 11, a signal receiver 12, and a distance sensor 13. The first sleeve 5 is fixedly connected to the top of the support plate 3. Guide protrusions are provided on both the front and rear sides of the first sleeve 5. Guide grooves are provided on both the front and rear sides of the second sleeve 6. The second sleeve 6 is slidably installed inside the first sleeve 5. The second sleeve 6 slides vertically through the guide grooves and the guide protrusions inside the first sleeve 5. Guide protrusions are provided on both the left and right sides of the second sleeve 6. Guide grooves are provided on both the left and right sides of the third sleeve 7. The third screw 4 is slidably installed inside the second sleeve 6. Sleeve 7 and third sleeve 7 slide vertically along the guide groove and guide protrusion in second sleeve 6. First screw 8 is rotatably installed on support plate 3 and is located inside first sleeve 5. Second sleeve 6 is threadedly connected to first screw 8. Ring 9 is rotatably installed in the lower part of second sleeve 6 and threaded sleeve 10 is fixedly connected to the top of ring 9. Guide grooves are opened on both the left and right sides of first screw 8. Guide protrusions are fixedly connected to both the left and right sides of threaded sleeve 10. Threaded sleeve 10 slides vertically along the guide protrusion and guide groove on first screw 8 and is located inside second sleeve 6. Third sleeve 7 is threadedly connected to threaded sleeve 10. Mounting plate 11 is fixedly connected to the top of third sleeve 7. Signal receiver 12 is installed at the bottom of mounting plate 11 by bolt connection. Distance sensor 13 is installed on support plate 3 by bolt connection. Distance sensor 13 and signal receiver 12 are located on the same horizontal line.

[0023] See Figure 2 , Figure 4 and Figure 5 As shown, it also includes a handwheel 20, and the ends of the first screw 8 and the second screw 14 are both fixedly connected to the handwheel 20.

[0024] When using this device, first spread out the three support rods 4 and place them against the ground to form a triangular support. Then, rotate the first screw 8 by handwheel 20. The first screw 8 drives the second sleeve 6, the ring 9, and the threaded sleeve 10 to move upward along the first sleeve 5. The first screw 8 drives the threaded sleeve 10 to rotate, and the threaded sleeve 10 drives the third sleeve 7 to move upward, thereby adjusting the height of the signal receiver 12. This allows for testing of buildings of different heights. The distance sensor 13 transmits a signal to the signal receiver 12, and the current height is obtained from the transmission distance, avoiding a large height difference between the measuring station and the target point.

[0025] Example 2: Based on Example 1, refer to Figure 5 As shown, it also includes a second screw 14, a guide sleeve 15 and a connecting rod 16. The second screw 14 is rotatably mounted on the bottom of the support plate 1. The guide sleeve 15 is threaded onto the second screw 14. Three connecting rods 16 are evenly spaced and hinged onto the guide sleeve 15. The connecting rods 16 are rotatably connected to the adjacent support rod 4.

[0026] See Figure 6 As shown, it also includes a rubber sleeve 19, and the lower end of the support rod 4 is fitted with a rubber sleeve 19.

[0027] See Figure 5 As shown, it also includes a bubble level 21, with three bubble levels 21 evenly spaced on the support plate 3.

[0028] When the equipment needs to be placed, the second screw 14 is rotated by the handwheel 20. The second screw 14 drives the guide sleeve 15 to move. The guide sleeve 15 drives the three connecting rods 16 to rotate, so that the connecting rods 16 squeeze the support rods 4 to open outward. This allows the three support rods 4 to open quickly, so as to quickly adapt to uneven terrain. By increasing the support span, the stability of the marker is significantly improved. When placed on the ground, the support plate 3 is accurately leveled by observing the bubble level 21. The rubber sleeve 19 increases the friction between the support rods 4 and the contact surface.

[0029] See Figure 5 and Figure 6 As shown, it also includes a connecting plate 17 and a fixing nail 18. The lower part of the support rod 4 is fixedly connected to the connecting plate 17, and the connecting plate 17 is threaded with the fixing nail 18.

[0030] After the support pole 4 is opened and placed on the ground, tighten the fixing nail 18 so that its tip is deeply embedded in the ground, effectively preventing the pole from sliding or tipping over due to wind or accidental collisions during field measurements, and ensuring the stability and reliability of the measurement data.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that variations may 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.
