Description

Technical Field

[0001] The utility model relates to the technical field of inclinometer tools, in particular to an anti-stuck inclinometer. Background Art

[0002] With the rapid development of the engineering construction field, inclinometers, as an important means of on-site monitoring of geotechnical engineering, are increasingly widely used in monitoring the deep horizontal displacement of surrounding rocks such as foundation pits and slopes. In the process of using inclinometers to monitor the horizontal displacement of surrounding rocks, it is usually necessary to bury an inclinometer tube with a groove inside to ensure that the inclinometer pulley moves up and down along the groove; the inclinometer tube is usually installed in a vertical borehole that passes through the unstable soil layer to the lower stable stratum. Inclinometer probes, control cables, pulley devices and readers are used to observe the deformation of the inclinometer tube. During observation, the probe moves from the bottom to the top of the inclinometer tube, pauses at a fixed interval and reads the inclinometer data. The inclination of the probe is measured by two force-balanced servo accelerometers. One accelerometer measures the longitudinal position of the inclinometer tube groove, that is, the inclination of the plane where the measuring wheel on the inclinometer probe is located. The other accelerometer measures the inclination perpendicular to the measuring wheel plane. The inclination can be converted into lateral displacement. By comparing the current and initial observation data, the change in lateral offset can be determined, showing the movement displacement of the stratum.

[0003] The inclinometer tube has four slots for fixing the pulley of the portable inclinometer probe. The probe is connected to one end of the cable connected to the readout instrument to observe the vertical tilt associated with the inclinometer. The conventional inclinometer probe has two sets of pulleys, 0.5m apart. The probe is read every 0.5m until it reaches the top of the inclinometer tube, and the forward inclinometer data is obtained. Then the probe is taken out, rotated 180 degrees and put back into the inclinometer tube, and the above steps are repeated to obtain the reverse inclinometer data.

[0004] Inclinometer tubes can be buried directly in the retaining piles or in the soil with the help of drilling equipment. Due to the shrinkage of concrete or improper construction, changes in soil horizontal pressure, improper splicing of inclinometer tube sections, etc., the inclinometer tube may be partially damaged or misaligned. The structure of the inclinometer probe pulley can easily cause the probe to get stuck and cannot be removed smoothly. The inclinometer probe is expensive and the inclinometer tube cannot be re-measured, which affects the quality of engineering monitoring and brings certain economic losses. Utility Model Content

DETAILED DESCRIPTION

[0038] The following is a specific embodiment of the present invention. People familiar with the technology can easily understand the other advantages and functions of the present invention from the contents disclosed in this specification. Obviously, the described embodiment is a part of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0039] like Figures 1 to 8 As shown, an anti-stuck inclinometer in the embodiment of the first aspect of the utility model comprises a measuring rod body 1, a first connecting assembly, two first pulleys 501, two first springs 601, a second connecting assembly, two second pulleys 502, two second springs 602 and an adjusting mechanism; the measuring rod body 1 is a tubular structure or a columnar structure, the diameter of the measuring rod body 1 is 30-40 mm, and the length is 700-800 mm; a first strip through opening 101 and a second strip through opening 102 are spaced apart along its radial direction, the first strip through opening 101 and the second strip through opening 102 are arranged in a cross shape, when the measuring rod body 1 enters the inclinometer tube 10 for vertical operation, the first strip through opening 101 is located above the second strip through opening 102; the opening lengths of the first strip through opening 101 and the second strip through opening 102 are both 10 cm, and the opening widths of the openings are both 15-20 cm.

[0040] The first connecting component is rotatably disposed in the first strip-shaped through-opening 101, and its two ends are respectively located at the two ends of the first strip-shaped through-opening 101, and the two first pulleys 501 are respectively installed at the two ends of the first connecting component, and the two first pulleys 501 are symmetrically arranged with respect to the axis of the measuring rod body 1, and the two first springs 601 are respectively arranged at the two ends of the first strip-shaped through-opening 101, and respectively abut against the side walls at the two ends of the first connecting component;

[0041] The second connecting component is rotatably disposed in the second strip-shaped through-opening 102, and its two ends are respectively located at the two ends of the second strip-shaped through-opening 102, the two second pulleys 502 are respectively installed at the two ends of the second connecting component, the two first pulleys 501 are symmetrically arranged with respect to the axis of the measuring rod body 1, and the two second springs 602 are respectively arranged at the two ends of the second strip-shaped through-opening 102, and respectively abut against the side walls at the two ends of the second connecting component;

[0042] The first connecting assembly and the second connecting assembly are arranged in a cross shape, wherein the first pulley 501 and the second pulley 502 are of the same size, and the center distance between the first pulley 501 and the second pulley 502 is 500 mm.

[0043] The adjusting mechanism is arranged in the measuring rod body 1, and the first connecting component and the second connecting component are both connected to the adjusting mechanism. Under the action of external force, the adjustment drives the first connecting component and / or the second connecting component to rotate, so that the first pulley 501 shrinks or extends toward the first strip through opening 101, and the second pulley 502 shrinks or extends toward the second strip through opening 102.

[0044] Working principle: When in use, the measuring rod body 1 is placed in the inclinometer tube 10, and the first pulley 501 and the second pulley 502 are respectively placed in the notch 1001 of the inclinometer tube 10. The measuring rod body 1 slides downward along the notch 1001 under the action of gravity. When encountering a damaged gap in the inclinometer tube 10, such as the first damaged part 11 of the inclinometer tube and / or the second damaged part 12 of the inclinometer tube, the first pulley 501 or the second pulley 502 is stuck, and the measuring rod body 1 stops moving downward. The first connecting assembly or / and the second connecting assembly are driven by the adjusting mechanism. The connecting assembly rotates toward the measuring rod body 1, causing the first pulley 501 to shrink toward the first strip-shaped through opening 101. At this time, the first connecting assembly compresses the first spring 601, and the measuring rod body 1 passes through the damaged gap of the inclinometer tube smoothly. The compressed first spring 601 is then released through the adjustment mechanism, and the first pulley 501 extends out to return to its original position, and continues to detect or retract along the slot 1001. Similarly, when the second pulley 502 encounters a damaged gap in the inclinometer tube 10, the adjustment method is the same as that of the first pulley 501, which will not be repeated.

[0045] The first connecting component includes two first connecting rods 2, which are symmetrically arranged on both sides of the first strip through opening 101, one end of the first connecting rod 2 is connected to the first strip through opening 101 through a pin shaft 3, the other end of the first connecting rod 2 is connected to the first pulley 501, the middle part of the side wall of the first connecting rod 2 is connected to one end of the first spring 601, the other end of the first spring 601 is connected to the measuring rod body 1, and the natural state of the first spring 601 is to pop the first connecting rod 2 away from the measuring rod body 1; the second connecting component includes two second connecting rods 4, which are symmetrically arranged on both sides of the second strip through opening 102, one end of the second connecting rod 4 is connected to the second strip through opening 102 through a pin shaft 3, and the other end of the second connecting rod 4 is connected to the second pulley 502. The middle part of the side wall of the second connecting rod 4 is connected to one end of the second spring 602, and the other end of the second spring 602 is connected to the measuring rod body 1. The natural state of the second spring 602 is to pop the second connecting rod 4 away from the measuring rod body 1; the first connecting rod 2 and the second connecting rod 4 are both metal rods, and at the same time, the angles between the first connecting rod 2 or the second connecting rod 4 and the measuring rod body 1 are both acute angles.

[0046] The adjusting mechanism comprises a hose 7 and a wire group 8. The hose 7 is provided with scale lines, with one mark every 0.5 m, so as to detect the vertical depth of the damaged position of the inclinometer tube. After the circumferential damaged position of the inclinometer tube is determined, the depth position of the damaged position can be further determined according to the scale lines on the hose. The bottom end of the hose 7 is connected with the measuring rod body 1. A channel 701 is provided on the hose 7 along the axial direction. One end of the wire group 8 passes through the channel 701 and then passes through the first strip through opening 101 to be connected with the first connecting component, and passes through the second strip through opening 102 to be connected with the second connecting component. The other end of the wire group 8 is arranged outside the top end of the hose 7 (on the ground). The wire group 8 is tensioned to control the contraction or extension of the first connecting component or / and the second connecting component. The specific operation is to pull the hose 7 upward while pulling the wire group 8 upward until the stuck pulley contracts. The position at this time is the damaged position of the inclinometer tube 10.

[0047] In addition, a guide wheel 9 is provided in the measuring rod body 1, and the wire group 8 is connected to the first connecting component and the second connecting component after passing around the guide wheel 9. The provision of the guide wheel 9 can make it easier for construction workers on the ground to pull the wire group.

[0048] The wire group 8 has four wires in total, two of which are connected to the side walls at both ends of the first connecting component, and the other two are connected to the side walls at both ends of the second connecting component. Four channels 701 can be opened, and after the four wires are passed through the four channels 701 in a one-to-one correspondence, the first wire is connected to the side wall of one of the first connecting rods 2, the second wire is connected to the side wall of another first connecting rod 2, the third wire is connected to the side wall of one of the second connecting rods 4, and the fourth wire is connected to the side wall of another second connecting rod 4. For easy distinction, a corresponding number is set on each wire, and the corresponding pulley can be controlled to retract or extend by tensioning the corresponding wire.

[0049] Although the utility model has been described in detail above with general descriptions and specific embodiments, it is obvious to those skilled in the art that some modifications or improvements can be made to the utility model. Therefore, these modifications or improvements made without departing from the spirit of the utility model are within the scope of protection claimed by the utility model.

Changes or adjustments to their relative relationships should be regarded as the scope of implementation of the present invention without substantially changing the technical content.
