The leveling ruler fixing unit includes a fixing connecting rod 11 and two ruler fixing clamps 12 , the two ends of the fixed connecting rod are respectively connected with a scale fixed connection clamp 12, the lifting and fixed clamping connector includes a cartridge 21 and a transverse connecting rod 22, the cartridge 21 is sleeved on the outer side of the fixed connecting rod 11, and the cartridge 21 is provided with a locking strip slot 23 in the axial direction, and a connecting plate 24 is connected to each side of the locking strip slot 23, and the two connecting plates 24 are locked and fixed by locking screws 25, and the transverse connecting rod 22 One end is connected with the cylinder body of the cartridge 21, and the other end of the transverse connecting rod 22 is connected with a connecting joint 26. The connecting joint 26 is connected with a connecting screw 27. A locking nut 28 is sleeved on the outer side of the threaded portion. The telescopic support includes two support rods 30. The butt joint 31 includes a pair of connecting rods 311, one end of the pair of connecting rods 311 is provided with a fixed connection hole 312, and the fixed connecting holes 312 on the pair of connecting rods 311 of the two support rods are sequentially sleeved on the threaded portion of the connecting screw 27 up and down. Below, the other end of the connecting rod 311 is connected with a U-shaped butt joint 313, the U-shaped butt joint 313 is connected with the upper end of the telescopic inner rod 32, the lower end of the telescopic inner rod 32 extends into the interior of the outer rod 33, and the telescopic inner rod 32 It is connected with the outer rod 33 by a grip-type fastening lock 34 , and the grip-type fastening lock 34 can adjust the length of the telescopic inner rod 32 inserted into the outer rod 33 .

[0038] The operation method of this precise geometric leveling measuring vertical ruler straightening device provided by the present invention is as follows:

[0039] Step 1) Place the ruler: fix the two rulers to the back of the clamp 12 leveling ruler;

[0040] Step 2) Erection device: place the midpoint of the bottom of the leveling rod on the point of the vertical ruler, the front of the leveling rod is opposite to the observation direction of the instrument, and perpendicular to the horizontal direction, loosen the locking nut 28, so that the two support rods of the telescopic support 3 30 and the leveling rod respectively form a triangle shape, tighten the locking nut 28, and then press the grip-type tightening lock 34 to make the telescopic inner rod 32 telescopic to an appropriate position so that the bottom end of the outer rod 33 is firmly supported on the ground, and then loosened Grip fastening lock 34;

[0041] Step 3) Adjustment accuracy: Hold the grip-type fastening locks 34 on the two support rods at the same time, and adjust the telescopic inner rod 32 up and down to a suitable position, so that the level bubble on the back of the leveling scale is level, and then release the grip-type fastening locks 34 The telescopic inner rod 32 and the outer rod 33 are locked and fixed, and the measurement can be performed;

[0042] Step 4) After the measurement is completed, remove the leveling rod, and store and pack the straightening device.

[0043] The straightening device of the vertical ruler for precise geometric leveling of the present invention has a compact structure and is easy to carry through the integrated setting, which can not only realize the high precision of the precise geometric leveling, but also can be used for electronic and optical levels at home and abroad. The leveling ruler has simple and accurate operation methods, fast identification and reading, and solves the measurement errors caused by the artificial ruler being not straight or unstable, and the unintentional ruler pad shaking, and eliminates the leveling ruler during the implementation of the leveling measurement. At the same time, it can reduce the labor intensity of the ruler.

[0044] Further, in the step 3), when the leveling transition is transferred, lift the two support rods slightly, take the ruler point as the fulcrum, turn them to the direction of the instrument, and adjust the leveling according to the operation of step 3). The level bubble on the back of the leveling scale is enough; when moving to a station, loosen the locking nut 28 and close the two support rods 30, as shown in Figure 4 As shown in the figure, vertically transport the straightening device to the next position, repeat the operations of steps 2) and 3) above to measure, realize the transition of the transfer station and transfer one leveling and multiple observations, which greatly shortens the field work. Test time.

[0045] Example 2:

[0046] On the basis of Embodiment 1, this embodiment provides a figure 1 As shown in the straightening device and the operation method of the vertical ruler for precision geometric leveling, the connecting rod 11 includes a straight rod. 12 connections.

[0047] like Figure 4 As shown in the figure, the two ruler fixing clamps 12 are fastened and placed at 1/3 and 2/3 of the back of the leveling ruler body. Figure 5 As shown, when the point of the ruler is flush with the ground, the cartridge 21 is fastened to the midpoint of the straight rod on the fixed connecting rod 11, as shown in Image 6 As shown in the figure, when the point of the ruler is protruding from the ground, the cartridge 21 should be adjusted downward along the long axis direction of the fixing rod 11 and fastened to an appropriate position, such as Figure 7 As shown, when the point of the ruler is low on the ground, the cartridge 21 should be adjusted upward along the long axis direction of the fixing rod 11 and fastened to a proper position.

[0048] Further, for the convenience of unscrewing and locking the locking nut 28 , a locking handle 29 is connected to the locking nut 28 .

[0049] Example 3:

[0050] On the basis of Embodiment 2, this embodiment provides a vertical straightening device for precision geometric leveling and an operation method thereof. In order to facilitate installation and disassembly, such as Figure 8 As shown, the upper end of the telescopic inner rod 32 is provided with a connecting head 35, and the connecting head 35 is provided with a connecting hole, such as Figure 9 and Figure 10 As shown, the U-shaped butt joint 313 is provided with docking holes 314 on opposite sides, the connecting head 35 is located in the U-shaped butt joint 313, and the connecting hole of the connecting head 35 communicates with the two docking holes 314, and passes through the U-shaped butt joint 313. Insert the horizontal axis screw into the three holes to connect the connector 35 and the U-shaped butt joint 313 .

[0051] like image 3 As shown, the grip type tightening lock 34 is provided on the outer side of the outer rod 33 to adjust the length of the telescopic inner rod 32 inserted into the outer rod 33. Applicability of the device.

[0052] like image 3 As shown, the bottom end of the outer rod 33 is connected with a foot peg 36 , the foot peg 36 is arranged in an inverted cone shape, and a foot pedal 37 is provided on the interface between the outer rod 33 and the foot peg 36 . It is supported on the ground by the inverted conical foot nails 36, which makes the device more stable, avoids the transitional transfer of the transfer station, and avoids the force sinking and rebounding or the moving point of the intermittent ruler pad, so as to realize the precise transmission of height difference. .
