Description

Technical Field

[0001] The utility model belongs to the technical field of drilling inclination measurement, and particularly relates to a drilling inclination measurement device. Background Art

[0002] Inclinometers are instruments used to measure the top angle and azimuth of engineering structures such as boreholes, foundation pits, foundations, walls, and dam slopes. They typically consist of a probe, cable, reader, and inclinometer tube. The inclinometer tube is buried during the construction of the foundation pit support structure. During actual measurement, the probe is connected to a graduated cable, the other end of which is connected to the reader. The probe's two pairs of guide wheels slide along the concave guide groove of the inclinometer tube to the bottom of the pipe. Then, a wire is pulled upward at regular intervals to take readings, thereby determining the relative inclination of the pipe to the vertical at each location.

[0003] Traditional inclinometers have significant shortcomings. Their guide wheels cannot be flexibly adjusted to the diameter of the inclinometer casing. This means that before each measurement, a guide wheel matching the diameter of the inclinometer casing must be installed and replaced before testing can begin. This not only increases the complexity and workload of measurement preparation, but also, in actual operation, the lack of a suitable guide wheel can delay measurement work and reduce work efficiency. To address this technical issue, a borehole inclinometer device is specifically designed to address this issue. Utility Model Content

[0004] To address the problem of guide wheels used in existing inclinometers, which lack flexibility to adjust according to the diameter of the inclinometer tube, resulting in poor applicability, the present invention provides a borehole inclinometer device. This device utilizes at least three movable rods with auxiliary wheels rotatably mounted on the outside of a protruding block with a through hole, and springs installed between the movable rods and the protruding block. In actual use, when the protruding block is placed in the inclinometer tube, the springs play a crucial role. Because different inclinometer tubes have different inner diameters, the springs adaptively adjust the position of the top of the movable rods according to the tube's inner diameter. This adaptive adjustment mechanism ensures that the auxiliary wheels at the top of the movable rods fit tightly against the inner wall of the inclinometer tube, achieving a good fit regardless of changes in the tube's inner diameter. This significantly enhances the device's applicability to inclinometer tubes of varying diameters, providing a strong guarantee for high-precision and efficient borehole inclinometer work. This effectively addresses the problem of guide wheels used in existing inclinometers, which lack flexibility to adjust according to the diameter of the inclinometer tube, resulting in poor applicability. The specific technical solutions are as follows:

[0005] A drilling inclinometer device comprises a protrusion with a through opening, at least three movable rods are rotatably mounted on the outer surface of the lower end of the protrusion at equal intervals in the circumferential direction, auxiliary wheels are rotatably mounted on the top ends of the movable rods, and springs are fixedly mounted between the movable rods and the outer surface of the protrusion, a traction mechanism for pulling the movable rods inward is mounted on the outer surface of the upper end of the protrusion, and a tightening bolt is threadedly mounted between the front surface of the protrusion and the through opening.

[0006] In the above technical solution, the outer surface of the upper end of the protrusion is provided with an external thread, the traction mechanism includes a nut threadedly connected to the external thread, the bottom end of the nut is rotatably mounted with a traction disc, the protrusion passes through the traction disc, and the lower surface of the traction disc is fixedly connected to at least three traction ropes at equal intervals in the circumferential direction, and the ends of the traction ropes away from the traction disc are fixedly connected to corresponding movable rods;

[0007] In the above technical solution, at least three pulley assemblies are fixedly installed on the outer surface of the protrusion at equal intervals in the circumferential direction, and the traction rope passes through the corresponding pulley assemblies, and the pulley assemblies are fixedly installed in the middle of the protrusion;

[0008] In the above technical solution, the traction rope is a steel wire rope with a diameter of one centimeter;

[0009] In the above technical solution, at least three U-shaped adapter blocks are fixedly installed on the lower surface of the protrusion in a circumferential direction, and the U-shaped adapter blocks are rotatably connected to the lower ends of the corresponding movable rods through rotating shafts;

[0010] In the above technical solution, the auxiliary wheel is a metal wheel made of high manganese steel.

[0011] In the above technical solution, mounting grooves are provided on the opposite surfaces of the protrusion and the movable rod, and the ends of the springs are fixedly mounted in the corresponding mounting grooves.

[0012] Compared with the prior art, the drilling inclination measuring device of the present invention has the following beneficial effects:

[0013] First, the present invention adaptively adjusts the position of the top of the movable rod so that the auxiliary wheel fits snugly against the inner wall of the inclinometer casing. This adaptive adjustment mechanism ensures that the auxiliary wheel at the top of the movable rod fits snugly against the inner wall of the inclinometer casing, achieving a good fit regardless of the inner diameter of the inclinometer casing. This greatly enhances its applicability to inclinometer casings of varying diameters, providing a strong guarantee for high-precision and efficient drilling inclinometer work.

[0014] Second, the utility model is provided with a traction mechanism, which can rotate the nut to move upward, drive the traction plate to move upward, and pull the movable rod inward through the traction rope to move, thereby changing the position of the auxiliary wheel inward to adapt to the inclinometer casing with a smaller inner diameter. This makes the operation of the movable rod more convenient and labor-saving during the inward adjustment process, greatly improving the adjustment efficiency and operational convenience, and providing strong support for the flexible application of the entire device under different inclinometer casing conditions.

DETAILED DESCRIPTION

[0022] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments 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 making creative efforts are within the scope of protection of the present invention.

[0023] In this embodiment, front, back, left, right, up and down are represented by Figure 1 Describes the datum. Figures 1-6 , the utility model provides a technical solution:

[0024] A drilling inclinometer device comprises a block 1 with a through opening 11, at least three movable rods 2 are rotatably installed on the outer surface of the lower end of the block 1 at equal intervals in the circumferential direction, auxiliary wheels 21 are rotatably installed on the top ends of the movable rods 2, and springs 3 are fixedly installed between the movable rods 2 and the outer surface of the block 1, a traction mechanism 4 for pulling the movable rod 2 inward is installed on the outer surface of the upper end of the block 1, and a tightening bolt 6 is screwed between the front surface of the block 1 and the through opening 11; in the above technical solution, an external thread 13 is provided on the outer surface of the upper end of the block 1, the traction mechanism 4 comprises a nut 41 screwed with the external thread 13, a traction disc 42 is rotatably installed on the bottom end of the nut 41, the block 1 passes through the traction disc 42, and at least three traction ropes 43 are fixedly connected to the lower surface of the traction disc 42 at equal intervals in the circumferential direction, and the end of the traction rope 43 away from the traction disc 42 is fixedly connected to the corresponding movable rod 2.

[0025] When using this device, combine Figure 3 and Figure 6 As shown, first, the inclinometer probe 8 is passed through the through-hole 11 of the protrusion 1 , and then the inclinometer probe 8 is firmly fixed in the through-hole 11 by tightening the fastening bolt 6 .

[0026] Next, the nut 41 is rotated, causing it to move upward. Because the traction disc 42 and nut 41 are rotationally connected, the upward movement of the nut 41 simultaneously drives the traction disc 42 upward. As the traction disc 42 moves upward, it generates an inward pulling force through the traction rope 43. This force acts on the corresponding movable rod 2, causing it to tilt inward, thereby changing the position of the auxiliary wheel 21. In this way, the device can adapt to the use requirements of inclinometer casings 7 with smaller inner diameters.

[0027] Conversely, when the nut 41 is rotated and moved downward, the traction plate 42 is driven downward by the nut 41. At this time, under the elastic force of the spring 3, the movable rod 2 flips outward, and the position of the auxiliary wheel 21 also changes accordingly, thereby meeting the use requirements of the inclinometer casing 7 with a larger inner diameter.

[0028] Compared to the guide wheels used in existing inclinometers, the auxiliary wheel 21 of this device offers significant advantages. It can be flexibly adjusted to the changes in the inner diameter of the inclinometer tube 7, ensuring a close fit between the auxiliary wheel 21 and the inner wall of the inclinometer tube 7, thereby better facilitating adaptive guidance. The entire operation process is simple and convenient, greatly improving the device's applicability.

[0029] In actual use, in order to reduce the wear of the edge of the protrusion 1 on the traction rope 43, Figure 1 and Figure 5As shown, at least three pulley assemblies 5 are fixedly installed on the outer surface of the protrusion 1 at equal intervals in the circumferential direction, and the traction rope 43 passes through the corresponding pulley assembly 5. The pulley assembly 5 is fixedly installed in the middle of the protrusion 1, as shown in FIG. Figure 5 As shown, the pulley assembly 5 is assembled by welding two pulleys. The pulley assembly 5 can guide the traction rope 43 and avoid contact with the edge of the protrusion 1 during use, thereby reducing wear and extending service life.

[0030] In order to further enhance its service life, the traction rope 43 needs to be set as a steel wire rope with a diameter of one centimeter. Compared with some nylon ropes, the service life of the steel wire rope is longer.

[0031] To improve the wear resistance of the auxiliary wheel 21 and prevent wear of the auxiliary wheel 21 from affecting the guiding effect in the inclinometer tube 7, the auxiliary wheel 21 is a metal wheel made of high-manganese steel. High-manganese steel has extremely strong wear resistance and can greatly reduce the loss of the auxiliary wheel 21 during use, thereby ensuring its guiding effect.

[0032] Specifically, if Figure 1 As shown, at least three U-shaped adapter blocks 12 are fixedly installed circumferentially on the lower surface of the protrusion 1. The U-shaped adapter blocks 12 are rotatably connected to the lower ends of the corresponding movable rods 2 through rotating shafts. The movable rods 2 are rotatably connected to the protrusion 1 through the U-shaped adapter blocks 12.

[0033] Specifically, if Figure 3 As shown, mounting grooves 14 are provided on the opposite surfaces of the protrusion 1 and the movable rod 2 , and the ends of the spring 3 are fixedly mounted in the corresponding mounting grooves 14 .
