Description

Technical Field

[0001] The invention relates to drilling equipment, in particular to a sliding type intelligent inclinometer probe adaptable to track change and rotation. Background Art

[0002] Inclinometer tubes are widely used in the measurement of deep horizontal displacement of soft soil foundations in reclamation projects. There are two pairs of mutually perpendicular guide grooves in the tube for the orientation of the inclinometer probe, and the angle between adjacent guide grooves is 90°. 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 estimation of the probe depth.

[0003] The specific inclinometer process requires that the sliding inclinometer slides from bottom to top along the track groove, measures every 50 cm and records the angle between the probe axis and the vertical line. After the inclinometer probe completes the full measurement of a pair of track grooves, it must be manually rotated 180° to re-measure the same pair 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.

[0033] like Fig. 9 As shown, the working principle of the above sliding intelligent inclinometer probe is:

[0034] The probe guide wheel gauge length is 500mm, which drives the probe to slide in the inclinometer tube, pausing once every 500mm to complete the angle measurement between the tube axis and the vertical line at the fixed depth. The auxiliary device at the top of the inclinometer tube includes three sections, namely the standard inclinometer tube, the grooveless section and the grooved section. After the probe moves upward into the auxiliary device, the upper guide wheel is at the entrance of the spiral track groove when the lower guide wheel is at the grooveless section. Fig.10 The guide wheel joint bearing of the probe guide wheel allows the guide wheel to be radially offset, and the single-point cantilever shaft of the probe guide wheel arm allows the guide wheel to deflect radially to a certain extent, such as Fig.11 , driving the probe as a whole to rotate. The lower guide wheel is radially biased under the drive of the probe's own rotation, and rolls upward along the spiral track on the inner wall of the grooveless section. After the upper guide wheel enters the vertical track, the guide wheel radially returns to a state perpendicular to the rotating shaft. When the probe moves downward, the guide wheel rolls along the vertical track groove into the inclinometer casing. The probe completes a 90-degree rotation in one upward movement in the auxiliary device.
