Description

Technical Field

[0001] The invention relates to drilling equipment, in particular to an auxiliary device for rotating and changing tracks of a sliding intelligent inclinometer probe. Background Art

[0002] Inclinometer tubes are widely used in the field of measuring deep horizontal displacement of soft soil foundation or slope rock and soil in engineering. There are two pairs of perpendicular guide grooves in the tube for the orientation of the inclinometer probe. The angle between adjacent guide grooves is 90°, and the relative guide grooves form a set of measuring tracks, which are recorded as AA' and BB'. The commonly used deep displacement monitoring method is mainly based on the portable inclinometer to regularly obtain the deformation data of the inclinometer tube. The portable inclinometer is a measuring instrument that connects the cable to the probe and connects it to the measuring instrument through a capstan. The probe responds to the deep horizontal displacement of the soil layer through a tilt sensor, etc. The cable is responsible for communication, connection and reading the probe depth.

[0003] The specific inclinometer process is that the sliding inclinometer slides from bottom to top along the guide groove, measures every 50 cm and records the angle between the probe axis and the vertical line. After the inclinometer probe measures along the AA' guide groove, it must be manually rotated 180° to make the probe guide wheel change track to the relative groove and then measure along the BB' guide groove. The same measurement procedure must be implemented for the two sets of track grooves. The sliding inclinometer probe must rotate 3 times to complete the entire measurement process of an inclinometer tube, and the probe must rotate a total of 450° in the same rotation direction. When measuring with existing sliding intelligent inclinometers, the probe steering must be completed with manual assistance, and the inclinometer method has problems such as long cycle and large human error.

[0006] Furthermore, the inner wall has a groove on the outer surface of the grooved tube for installing the upper reset button and the lower reset button, a through hole for the upper reset button and the lower reset button to pass through is set in the groove, a reset spring hole is set on the side wall of the groove, and a reset spring is set on the side wall of the upper reset button and the lower reset button, and a reset spring is set between the reset spring holes of the upper reset button and the lower reset button and the reset spring holes on the corresponding side wall of the groove.

[0007] Furthermore, it also includes an annular slide bed sleeved on the outer surface of the grooved tube on the inner wall, and the annular slide bed is used to limit the upper reset button and the lower reset button.

[0008] Furthermore, four upper reset keys and four lower reset keys are respectively provided corresponding to the four spiral grooves.

[0009] Further, the upper reset key includes an upper positioning portion and an upper guide portion protruding outward from the upper positioning portion, the upper positioning portion is arranged in a groove on the outer surface of the inner wall groove tube, and a reset spring hole is arranged on the side wall of the upper positioning portion, and the upper guide portion passes through the through hole of the inner wall groove tube and protrudes outward from the bottom of the spiral groove;

[0010] The lower reset button includes a lower positioning portion and a lower guide portion protruding outward from the lower positioning portion. The lower positioning portion is arranged in a groove on the outer surface of the inner wall groove tube, and a reset spring hole is arranged on the side wall of the lower positioning portion. The lower guide portion passes through the through hole of the inner wall groove tube and protrudes outward from the bottom of the vertical groove.

[0011] Furthermore, the extension direction of the upper guide portion forms an acute angle with the vertical direction, and the bottom of the upper guide portion is close to the vertical groove, and the top of the upper guide portion is close to the spiral groove;

[0012] The extension direction of the lower guide portion forms an acute angle with the vertical direction. The bottom and top of the lower guide portion are respectively located on both sides of the vertical groove, and the top of the lower guide portion is close to the entrance of the spiral groove.

[0013] Furthermore, the end surface of the upper guide portion close to the spiral groove is an inclined surface, and the upper end surface of the lower guide portion is an inclined surface.

[0014] Furthermore, the inner diameter of the tube without grooves on the inner wall is larger than the inner diameter of the non-vertical groove and spiral groove parts of the tube with grooves on the inner wall.

The probe can rotate 180° by two upward movements and one downward movement, that is, the probe guide wheel automatically changes track to the relative groove for continuous measurement, achieving the goal of unattended measurement, greatly reducing the demand for manpower.

[0030] like Figures 1 to 3 As shown, an auxiliary device for rotating and changing the track of a sliding intelligent inclinometer probe in this embodiment is a circular pipe section with the same outer diameter as the inclinometer tube 1 and a height of 1.0m, comprising an inner wall grooveless tube 2 and an inner wall grooved tube 3 connected to the upper end of the inclinometer tube 1, the inner wall grooveless tube 2 is arranged between the inclinometer tube 1 and the inner wall grooved tube 3, the inner wall grooved tube 3 comprises four vertical grooves 31 arranged corresponding to the inclinometer tube 1 and a spiral groove 32 arranged between the vertical grooves 31, the spiral groove 32 connects two adjacent vertical grooves 31, the inner diameter of the inner wall grooveless tube 2 is larger than the inner diameter of the inner wall grooved tube 3 non-vertical groove 31 and the spiral groove 32 part, and the guide wheel of the probe can only enter the inner wall grooved tube 3 from the inner wall grooveless tube 2 through the vertical groove 31 of the inner wall grooved tube 3.

[0031] like Figure 4 As shown, a lower reset button 6 is provided in the vertical groove 31 at the entrance of the spiral groove 32, and an upper reset button 5 is provided at the exit of the spiral groove 32. Four upper reset buttons 5 and four lower reset buttons 6 are provided corresponding to the four vertical grooves 31 and the four spiral grooves 32, respectively. The upper reset button 5 and the lower reset button 6 are elastically connected to the grooved tube 3 on the inner wall, as shown in FIG. Figure 5 As shown, the outer surface of the inner wall grooved tube 3 is provided with a groove 4 for installing the upper reset button 5 and the lower reset button 6, a through hole is provided in the groove for the upper reset button 5 and the lower reset button 6 to pass through, a reset spring hole 9 is provided on the side wall of the groove, a reset spring hole 10 is provided on the side wall of the upper reset button 5 and the lower reset button 6, and a reset spring is provided between the reset spring hole 10 of the upper reset button 5 and the lower reset button 6 and the reset spring hole 9 on the corresponding side wall of the groove. The annular slide bed 7 is sleeved on the outer surface of the inner wall grooved tube 3 and is located outside the groove. The annular slide bed 7 is used to limit the upper reset button 5 or the lower reset button 6 to prevent the upper reset button 5 and the lower reset button 6 from detaching from the inner wall grooved tube 3. The structural schematic diagram of the annular slide bed 7 is shown in Figure 6 shown.

[0032] like Figure 7As shown in (a), the upper reset button 5 includes an upper positioning portion 51 and an upper guide portion 52 protruding outward from the upper positioning portion, the upper positioning portion 51 is arranged in the groove 4 on the outer surface of the inner wall grooved tube 3, and the side wall of the upper positioning portion 51 is provided with a reset spring hole 10, the upper guide portion 52 passes through the through hole of the inner wall grooved tube 3, and protrudes outward from the bottom of the spiral groove 32, the extension direction of the upper guide portion 52 forms an acute angle with the vertical direction, and the bottom of the upper guide portion is close to the vertical groove, and the top of the upper guide portion is close to the spiral groove.

[0033] like Figure 7 As shown in (b), the lower reset button 6 includes a lower positioning portion 61 and a lower guide portion 62 protruding outward from the lower positioning portion, the lower positioning portion 61 is arranged in the groove 4 on the outer surface of the inner wall grooved tube 3, and the side wall of the lower positioning portion 61 is provided with a reset spring hole 10, the lower guide portion 62 passes through the through hole of the inner wall grooved tube 3, and protrudes outward from the bottom of the vertical groove 31, the extension direction of the lower guide portion 62 forms an acute angle with the vertical direction, the bottom and top of the lower guide portion are respectively located on both sides of the vertical groove, and the top of the lower guide portion is close to the entrance of the spiral groove.

[0034] When the lower reset button 6 is in the initial state, the lower guide of the lower reset button 6 protrudes outward from the bottom of the vertical groove, blocks the vertical groove and guides the entrance of the spiral groove. When the lower guide of the lower reset button 6 is squeezed, the vertical groove is connected; when the upper reset button 5 is in the initial state, the upper guide of the upper reset button 5 protrudes outward from the bottom of the spiral groove to block the exit of the spiral groove. When the upper reset button 5 is squeezed, the exit of the spiral groove is connected with the vertical groove. The end surface of the upper guide close to the spiral groove is an inclined surface, and the upper end surface of the lower guide is an inclined surface, which is convenient for the guide wheel of the probe to squeeze the reset button.

[0035] The working principle of the above auxiliary device is:

[0036] like Figure 8 As shown, the sliding intelligent inclinometer probe 8 includes an upper guide wheel 81 and a lower guide wheel 82. The inclinometer probe slides up and down along the track groove with the guide wheels, and the distance between the upper and lower guide wheel shafts is 500 mm.

[0037] When the probe of the sliding intelligent inclinometer rises along the inclinometer pipe 1 and exceeds the pipe mouth, the upper guide wheel enters the non-groove section. Fig. 9 and Fig.10 As shown, when the probe rises in the groove, it encounters the lower reset button 6 and enters the spiral track, prompting the probe to start rotating. At this time, the lower guide wheel can rotate along the inner tube wall with the probe in the grooveless section. When the upper guide wheel breaks the upper button of the track groove reset button and enters the vertical track, the lower guide wheel just enters the vertical track. At this point, the probe completes a 90° rotation, and the upper guide wheel enters the adjacent vertical track. Each time the probe rises, the probe rotates 90° and the guide wheel changes track.

[0038] When the sliding intelligent inclinometer probe moves downward along the vertical track groove under the action of its own weight, Fig.11As shown, the upper reset button 5 blocks the upper guide wheel and the lower guide wheel from entering the spiral groove. The upper guide wheel and the lower guide wheel continue to descend along the vertical groove. When the upper guide wheel pushes the lower button of the track reset button to reach the grooveless section, the lower guide wheel has entered the track groove of the standard inclinometer tube. When continuing to descend, the lower guide wheel guides the probe to enter the standard inclinometer tube, and then the measurement process begins. The probe does not rotate or change track during the descent process.
