Description

Technical Field

[0001] This invention relates to installation equipment, and more specifically to an installation device for cage-type sensor brackets and deep hole sensors. Background Technology

[0002] Deep borehole sensors have wide applications in engineering construction, mining, geological exploration, and scientific research on soil and rock media. To obtain the mechanical parameters of soil and rock media, deep borehole sensors are often installed inside a cage-type sensor support, which then positions the sensor at a specific location within the deep borehole. Typically, the cage-type sensor support consists of an open cylindrical upper and lower connector, and four steel bars uniformly welded circumferentially to the outer walls of the upper and lower connectors. The upper and lower connectors have the same diameter and are coaxially aligned, with the length of the four steel bars parallel to their axes. The deep borehole sensor is fixedly installed between two of these steel bars. Therefore, accurately obtaining information such as the tilt angle, rotation angle, and direction of the cage-type sensor support is crucial for adjusting the deep borehole sensor's attitude and confirming its final state.

[0003] Currently, the attitude adjustment and final verification during the installation process of cage-type sensor brackets and deep hole sensors face the following three challenges:

[0004] (1) The inclination measurement of the cage-type sensor bracket is inconvenient.

[0005] Due to the complex environment at the construction site of deep hole sensors, it is difficult to establish a suitable measurement benchmark in most cases, and it is also difficult to fix the measurement tools, which makes it inconvenient to measure the tilt angle of deep hole sensors and results in a large error.

[0006] (2) It is difficult to measure the rotation angle of the cage-type sensor bracket.

[0007] The cage-type sensor bracket is prone to rotation during installation. Because it is difficult to establish an feasible measurement benchmark for its rotation angle, traditional angle measurement tools are basically ineffective.

[0008] (3) The direction indication of the deep hole sensor is not obvious.

[0009] To avoid the influence of interface effects, deep hole sensors are generally installed below the middle or even at the bottom of the cage-type sensor bracket. After the deep hole sensor is installed according to the pre-calculated angle, the direction of the deep hole sensor is not visible. As a result, when confirming and adjusting the angle, it is not possible to clearly grasp the movement and final state of the deep hole sensor, which makes the final confirmation of the deep hole sensor difficult.

[0010] The above three issues often result in the inability to accurately and efficiently adjust the posture of the cage-type sensor bracket and the deep hole sensor when installing them into the deep hole. Summary of the Invention

[0011] To address the technical problem of not being able to accurately and efficiently adjust the posture of a cage-type sensor bracket and a deep-hole sensor supported within the cage-type sensor bracket when inserting them into a deep hole, this invention provides an installation device for a cage-type sensor bracket and a deep-hole sensor.

[0012] The inventive concept of this invention:

[0013] Based on the cage-type sensor bracket itself, the tilt and rotation angle measurement benchmarks are established. Based on the gravity effect and torque principle, the tilt and rotation angles of the cage-type sensor bracket are accurately measured.

[0032] Furthermore, the tilt scale is fan-shaped, with one straight edge fixed to the torsion arm and the other straight edge fixed to the angle indicator, and the scale is set around its arc edge; the tail of the tilt pointer is rotatably connected to the center of the tilt scale.

[0033] Furthermore, a pin is fixedly connected to the tilt scale near the center; the axis of the pin is perpendicular to the sector of the tilt scale.

[0034] The tail of the tilt pointer is rotatably mounted on the pin, thereby enabling a rotatable connection between the tail of the tilt pointer and the tilt dial.

[0035] Furthermore, the direction indicator unit includes an indicator bracket, a direction indicator plate, a pitch angle measurement sensor, and a locking pin;

[0036] The indicator holder is used to be snapped onto the steel strip on the cage-type sensor bracket for mounting the deep hole sensor;

[0037] The locking pin is rotatably connected to the outside of the indicator card holder;

[0038] Both the direction indicator and the pitch angle measurement sensor can be rotatably mounted on the locking pin.

[0049] The beneficial effects of this invention are:

[0050] 1. The present invention provides an installation device for a cage-type sensor bracket and a deep hole sensor, comprising an angle measurement unit, an inclination measurement unit, and a direction indication unit; the angle measurement unit can measure the rotation angle of the cage-type sensor bracket and the deep hole sensor, the inclination measurement unit can measure the tilt angle of the cage-type sensor bracket, and the direction indication unit can indicate the orientation of the deep hole sensor after it enters the deep hole; the combination of the three units can accurately and efficiently indicate the installation posture of the cage-type sensor bracket and the deep hole sensor in the deep hole, making the installation and adjustment of the two simpler and more convenient.

[0051] 2. The present invention provides an installation device for a cage-type sensor bracket and a deep hole sensor. Based on the effects of gravity and torque, the gravity of the tilt measurement unit provides rotational power for the rotation indicator in the rotation measurement unit. The measurement base and the rotation pointer provide a reference for the rotation measurement, thereby realizing the rotation measurement of the cage-type sensor bracket. The measurement results are accurate, reliable and can be displayed in real time.

[0052] 3. The present invention provides an installation device for a cage-type sensor bracket and a deep hole sensor. Based on the principle of gravity, its tilt measuring unit is always in a vertical plane. At the same time, a weight is used to pull the tilt pointer to rotate on the fan-shaped tilt scale to indicate the axial tilt angle of the entire cage-type sensor bracket. This realizes the tilt angle measurement of the cage-type sensor bracket and the deep hole sensor. The measurement results are accurate, reliable and can be displayed in real time.

[0053] 4. The present invention provides an installation device for a cage-type sensor bracket and a deep hole sensor. Its direction indication unit is provided with an indicator bracket, a pitch angle measuring sensor and a direction indicator plate. The position of the indicator bracket relative to the steel bar is fixed, and the deep hole sensor is fixed relative to the steel bar. Therefore, with the indicator bracket as the reference and the measurement data of the pitch angle measuring sensor and the deep hole sensor as the reference, the direction of the direction indicator plate can be adjusted to be consistent with the installation direction of the deep hole sensor.

[0054] 5. The present invention provides an installation device for a cage-type sensor bracket and a deep hole sensor. Its rotation measurement unit uses a ball bearing bracket and balls as rotational support between the measuring base and the rotation indicator disk, which transforms sliding friction into rolling friction, greatly reducing the friction between the measuring base and the rotation indicator disk, making the rotation of the rotation indicator disk smoother and the position more accurate, and improving the reliability of the rotation measurement results.

[0061] The technical solution of the present invention will be clearly and completely described below with reference to the accompanying drawings and embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0062] The present invention provides an installation device for a cage-type sensor bracket and a deep hole sensor. Specifically, it is mainly used to install the cage-type sensor bracket and the deep hole sensor into a predetermined position in a rock deep hole in a preset posture. The cage-type sensor bracket is used to support the deep hole sensor, that is, the deep hole sensor is installed in the cage-type sensor bracket 1.

[0063] like Figure 1 As shown, the installation device provided in this embodiment of the invention includes a rotation angle measuring unit 2, a tilt angle measuring unit 3, and a direction indicating unit 4.

[0064] Combination Figure 2 and Figure 3As shown, the angle measuring unit 2 includes a cylindrical measuring base 21 for circumferentially fixed and fitted outside the cage-type sensor bracket 1, an angle indicator disk 22 rotatably fitted outside the measuring base 21, and an annular ball bearing bracket 25 disposed between the measuring base 21 and the angle indicator disk 22; a plurality of second set screws 27 are threaded around the measuring base 21 in its circumferential direction; each second set screw 27 penetrates the inner and outer walls of the measuring base 21 to fasten the relative position of the measuring base 21 and the cage-type sensor bracket 1. A circular angle scale 23 is mounted on the upper end of the angle indicator 22; the plane of the angle scale 23 is perpendicular to the axis of the angle indicator 22, and its axis is on the same straight line as the axis of the angle indicator 22; an angle pointer 24 is provided on the upper surface of the measuring base 21; the angle pointer 24 is located above the angle scale 23, its direction is perpendicular to the axis of the measuring base 21, and its needle corresponds to the scale on the angle scale 23; multiple ball bearing holes are evenly arranged around the circumference of the ball bearing bracket 25; a ball bearing 26 is embedded in each ball bearing hole; the ball bearing 26 and the corresponding ball bearing hole wall are... The measuring base 21 has a base annular groove 211 on its outer wall and an angle indicator disk 22 has an angle indicator disk annular groove 221 on its inner wall. The ball bearing bracket 25 and all the balls 26 are arranged between the base annular groove 211 and the angle indicator disk annular groove 221. The two sides of the balls 26 can roll into contact with the bottom of the base annular groove 211 and the angle indicator disk annular groove 221, respectively. The balls 26 can greatly reduce the rotational friction between the measuring base 21 and the angle indicator disk 22, so that the angle pointer 24 can accurately measure the rotation angle of the cage sensor bracket 1 relative to the previous state in conjunction with the angle scale 23.

[0065] The tilt measurement unit 3 is fixed to the outer ring wall of the angle indicator disk 22, and is used to measure the tilt angle of the central axis of the cage-type sensor bracket 1. Simultaneously, it provides rotational power to the angle indicator disk 22 based on gravity. Specifically, in conjunction with... Figure 2 and Figure 3As shown, the tilt measuring unit 3 includes a torsion arm 31 fixed at one end to the outer ring wall of the tilt indicator 22, a torsion ball 32 disposed at the other end of the torsion arm 31, a tilt scale 33 disposed between the torsion arm 31 and the generatrix of the outer ring wall of the tilt indicator 22, a tilt pointer 34 rotatably connected to the tilt scale 33 by a needle tail, and a weight 36 connected to the needle tip of the tilt pointer 34 by a flexible wire 35; the length direction of the torsion arm 31 is perpendicular to the axis of the tilt indicator 22, and is on the same straight line as the torsion ball 32; the tilt scale 33 is fan-shaped, with one straight line One side is fixedly connected to the torsion arm 31, and the other straight side is fixedly connected to the angle indicator 22; the scale on the tilt scale 33 is arc-shaped and arranged around the fan-shaped arc edge, with its center located at the intersection of the torsion arm 31 and the angle indicator 22; a pin 331 is fixedly connected to the tilt scale 33 near the center; the axis of the pin 331 is perpendicular to the fan surface of the tilt scale 33; the tail of the tilt pointer 34 is rotatably fitted onto the pin 331, thereby realizing that the tail of the tilt pointer 34 is rotatably connected to the tilt scale 33, and the tip of the tilt pointer 34 corresponds to the scale on the tilt scale 33.

[0066] When the cage-type sensor bracket 1 is tilted, the torsion ball 32 and the lowest point in the circumference are separated by a height difference, which in turn generates a torsional torque, causing the angle indicator 22 and the angle scale 23 to rotate, so that the torsion ball 32 is always at the lowest point. This establishes a constant reference for the angle measurement of the cage-type sensor bracket 1 and the corresponding deep hole sensor. The tilt scale 33, tilt pointer 34 and weight 36 also rotate accordingly. The tilt angle of the cage-type sensor bracket 1 is indicated on the tilt scale 33 by the tilt pointer 34.

[0067] Combination Figure 2 , Figure 3 and Figure 4As shown, the direction indicating unit 4 is used to install on the cage-type sensor bracket 1 to indicate the direction of the deep hole sensor inside. Specifically, the direction indicating unit 4 includes an indicating bracket 41, a direction indicating plate 42, a pitch angle measuring sensor 43, and a locking pin 46. The indicating bracket 41 is used to be clamped onto the steel strip 11 on the cage-type sensor bracket 1 for mounting the deep hole sensor. The indicating bracket 41 is a U-shaped bracket, with its two parallel arms and U-shaped base being rectangular plates. One of the parallel arms is referred to as the measuring plate. At least two first set screws 45 are threaded onto the measuring plate to secure the relative position between the indicating bracket 41 and the corresponding steel strip 11. A first-stage stepped hole 411 is provided in the middle of the measuring plate. The small hole of the first-stage stepped hole 411 is a threaded hole, and the threaded hole is located close to the inner wall of the measuring plate. The locking pin 46 is rotatable. The direction indicator plate 42 and the pitch angle measuring sensor 43 are rotatably mounted on the locking pin 46. One end of the direction indicator plate 42 is triangular so that the direction can be indicated through its sharp corner. The direction indicator plate 42 is provided with a second-stage step hole 421, and the large hole of the second-stage step hole 421 is set close to the measuring plate. The direction indicator plate 42 is also provided with a pitch angle display module 44. The pitch angle measuring sensor 43 is set between the measuring plate of the indicator plate 41 and the direction indicator plate 42. Its inner ring is fixedly connected to the direction indicator plate 42, and its outer ring is fixedly connected to the indicator plate 41. The pitch angle measuring sensor 43 is electrically connected to the pitch angle display module 44. The locking pin 46 includes a small-diameter stud 461, a large-diameter shaft 462, and a rotating disk 463 connected coaxially in sequence; the small-diameter stud 461 is threadedly connected to the small hole of the first-stage stepped hole 411; the large-diameter shaft 462 is rotatably fitted with a direction indicator plate 42 and a pitch angle measuring sensor 43, and the pitch angle measuring sensor 43 is located in the large hole of the first-stage stepped hole 411 and the large hole of the second-stage stepped hole 421.

[0068] The direction indicator unit 4 positions the steel strip 11 using the indicator holder 41. Then, based on the alignment of the long side of the indicator holder 41 and the long side of the direction indicator plate 42, and using the included angle between the deep hole sensor and the steel strip as a reference, the included angle between the long side of the direction indicator plate 42 and the indicator holder 41 is adjusted. This included angle is measured by the pitch angle measuring sensor 43 and displayed by the pitch angle display module 44, so that the pointed direction of the direction indicator plate 42 is consistent with the installation direction of the deep hole sensor. Then, the locking pin 46 is tightened to fix the relative position of the direction indicator plate 42 and the indicator holder 41. Because, after the deep hole sensor enters the deep hole in the rock, the operator can know the current direction of the deep hole sensor regardless of its posture.

[0069] It should be noted that the device that extends into the deep hole in the rock is usually a multi-section cage-type sensor bracket connected coaxially in sequence. Therefore, during use, the rotation angle measuring unit 2, the tilt angle measuring unit 3, and the direction indicating unit 4 are all installed on a cage-type sensor bracket located outside the deep hole in the rock, so that the operator can easily observe and confirm.

[0070] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions within the technical scope disclosed in the present invention should be covered within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
