Description

Technical Field

[0001] This utility model relates to the field of underground construction equipment technology, and in particular to a shock-absorbing gyroscope device. Background Technology

[0002] Typically, before coal mining, gas drainage is required by drilling boreholes in the coal seam, necessitating the drilling of numerous gas drainage holes underground. To ensure underground safety and a high borehole success rate, the drilling rig must operate according to pre-designed azimuth and pitch angles. Precisely determining the borehole opening angle is a prerequisite for accurate control of the drilling trajectory. A gyroscope is an inertial sensor that uses changes in angular velocity to measure an object's attitude. In recent years, with the development of technologies such as microelectromechanical systems (MEMS) and fiber optic gyroscopes, the application of gyroscopes in underground drilling rigs has become increasingly widespread, becoming a core component for accurate attitude and trajectory measurement in mining drilling rigs. Drilling rigs generate significant vibrations during operation. To prevent damage to the gyroscope from these vibrations, existing gyroscope devices can usually only be placed on the drilling rig for positioning while drilling is stopped, and then removed after positioning, a cumbersome operation. Utility Model Content

[0003] In view of the shortcomings of the prior art, the technical problem to be solved by this utility model is: how to provide a shock-absorbing gyroscope device with a reasonable structural design that can switch between shock-absorbing state and north-finding working state.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0005] A shock-absorbing gyroscope device includes a base and a gyroscope module. A shock-absorbing seat is disposed above the base, and the gyroscope module is mounted on the shock-absorbing seat via distributed elastic shock-absorbing elements. One side of the gyroscope module has a positioning seat disposed opposite to it. The device also includes a reciprocating drive mechanism, the drive end of which is correspondingly disposed to the shock-absorbing seat, the gyroscope module, or the positioning seat, and can drive the corresponding shock-absorbing seat, the gyroscope module, or the positioning seat to reciprocate along the opposite direction of the gyroscope module and the positioning seat, so that the gyroscope module can be pressurized and fixed on the positioning seat or detached from the positioning seat.

[0006] In the above structure, the gyroscope module is mounted on the shock absorber seat through distributed elastic shock absorbers. The shock absorber seat, gyroscope module or positioning seat can reciprocate under the drive of the reciprocating drive mechanism, so that the gyroscope module can be fixed on the positioning seat or detached from the positioning seat under pressure. When the gyroscope is needed for north-finding, the drilling rig stops working. The reciprocating drive mechanism drives the shock absorber to move the gyroscope module toward the positioning seat. The shock absorber applies pressure to the gyroscope module through its elastic damping components, pressing the gyroscope module firmly onto the positioning seat, thus securing the gyroscope module and allowing it to enter the north-finding state. Alternatively, the reciprocating drive mechanism directly drives the gyroscope module toward the positioning seat. In this case, the change in the relative position between the gyroscope module and the shock absorber is compensated for by the elastic damping components. Under the action of the reciprocating drive mechanism, the gyroscope module is directly pressed and fixed onto the positioning seat, achieving self-fixation and allowing it to enter the north-finding state. Or, the reciprocating drive mechanism drives the positioning seat toward the gyroscope module. When the positioning seat and the gyroscope module come into contact and abut against each other, the shock absorber applies a reverse force to the gyroscope module through its elastic damping components, thus pressing the gyroscope module firmly onto the positioning seat, achieving self-fixation and allowing it to enter the north-finding state. When the drilling rig is preparing to drill, the gyroscope is switched to vibration-damping mode. The reciprocating drive mechanism moves the vibration damping base, gyroscope module, or positioning base, causing the gyroscope module and positioning base to move away from each other until the gyroscope module detaches from the positioning base. At this point, the gyroscope module is connected to the vibration damping base through distributed elastic damping components. Vibrations generated by the drilling rig are transmitted to the vibration damping base and then amplified by the elastic damping components, thereby reducing or eliminating the vibration experienced by the gyroscope module and protecting it. By switching between north-finding and vibration-damping modes via the reciprocating drive mechanism, the gyroscope device can be directly installed on the drilling rig without frequent removal, greatly reducing workload.

[0007] Furthermore, the gyroscope module and the positioning base have a corresponding positioning structure, which is used to fix the gyroscope module on the positioning base at a preset position.

[0008] In this way, the positioning structure ensures that the gyroscope module and the positioning base always maintain a relative preset position, avoiding deviations in their fixed positions that could affect the orientation results of the gyroscope device, thus helping to ensure the reliability and consistency of the detection results.

[0009] Furthermore, the positioning structure includes at least three sets of correspondingly arranged positioning posts and positioning holes, with the corresponding positioning posts and positioning holes respectively arranged on two opposite sides of the gyroscope module and the positioning base; the end of the positioning post has a positioning cone with a gradually decreasing diameter, the maximum diameter of the positioning cone being greater than the inner diameter of the positioning hole, and the minimum diameter being less than the inner diameter of the positioning hole.

[0010] In this way, the positioning cone at the end of the positioning post allows for better alignment between the positioning post and the positioning hole. Simultaneously, the outer conical surface of the positioning cone acts as a guide, making it easier for each positioning post to become coaxial with the positioning hole. Furthermore, using at least three sets of corresponding positioning posts and positioning holes, a fixed positioning plane can be defined, ensuring consistent relative position between the gyroscope module and the positioning base.

[0011] Furthermore, the positioning structure includes a pair of magnets that are respectively disposed on two opposite sides of the gyroscope module and the positioning base.

[0012] In this way, the gyroscope module and the positioning base can be positioned relative to each other by using a pair of magnets, and the magnets can also enhance the fixation reliability between the two.

[0013] Furthermore, the elastic damping components are arranged circumferentially along the reciprocating motion path of the damping seat, gyroscope module, or positioning seat.

[0014] In this way, when the reciprocating motion mechanism drives the shock absorber, gyroscope module, or positioning base to fix the gyroscope module under pressure on the positioning base, the elastic shock absorber can apply a distributed force to the gyroscope module in the circumferential direction, thereby avoiding uneven force on the gyroscope module and causing it to tilt. This helps to make the pressure fixation between the gyroscope module and the positioning base more stable and reliable, and improves the reliability and consistency of the test results.

[0015] Furthermore, the reciprocating drive mechanism is a cam drive mechanism or a linear drive mechanism, and is located on the side of the gyroscope module away from the positioning seat; the cam drive mechanism includes a cam for pushing the gyroscope module; the linear drive mechanism has a push rod for pushing the gyroscope module, and the push rod is directed toward the gyroscope module.

[0016] In this way, since the cam drive mechanism or linear drive mechanism is located on the side of the gyroscope module away from the positioning seat, the cam or push rod can push the gyroscope module towards the positioning seat, allowing the gyroscope module to be fixed on the positioning seat under pressure and switch to the north-finding working state. Conversely, once the gyroscope module loses the push of the cam or push rod, it will reset under the action of the elastic damping component and switch to the shock-absorbing state.

[0017] Furthermore, one side of the shock absorber or positioning seat is hinged to the base via a hinge shaft orthogonal to the reciprocating motion path. A return spring is also provided between the base and the hinged shock absorber or positioning seat to keep the shock absorber and positioning seat away from each other. The reciprocating drive mechanism is a cam drive mechanism or a linear drive mechanism and is located outside the hinged shock absorber or positioning seat. The cam drive mechanism includes a cam for pushing the hinged shock absorber or positioning seat. The linear drive mechanism has a push rod for pushing the hinged shock absorber or positioning seat, and the push rod faces the hinged shock absorber or positioning seat.

[0018] Thus, when the reciprocating motion path is horizontal, the hinge of the damping seat or positioning seat is vertically positioned; when the reciprocating motion path is vertical, the hinge of the damping seat or positioning seat is horizontally positioned. Simultaneously, regardless of whether the damping seat or positioning seat is hinged, the return spring acts on the hinged components, causing the damping seat and positioning seat to move away from each other. When the cam or push rod of the reciprocating drive mechanism pushes the hinged damping seat or positioning seat inward, the damping seat and positioning seat will move closer together, and the gyroscope module will be pressed and fixed on the positioning seat, thus switching to the north-finding mode. Once the cam or push rod of the reciprocating drive mechanism moves away, the hinged damping seat or positioning seat will rotate outward under the action of the return spring, the gyroscope module will lose external pressure, detach from the positioning seat, and switch to the vibration-damping mode.

[0019] Furthermore, the reciprocating drive mechanism includes a linear guide mechanism arranged along the reciprocating motion path, and the shock absorber or positioning seat is connected to the sliding part of the linear guide mechanism; the reciprocating drive mechanism also includes a cam drive mechanism or a linear drive mechanism for driving the shock absorber or positioning seat to move along the linear guide mechanism; the cam drive mechanism includes a return spring for moving the shock absorber and positioning seat away from each other and a cam for pushing the shock absorber or positioning seat to move in the direction of compressing the return spring; the linear drive mechanism is arranged parallel to the linear guide mechanism and has a drive part for connecting the shock absorber or positioning seat.

[0020] Thus, regardless of whether the linear guide mechanism is horizontally or vertically positioned, the damping seat or positioning seat reciprocates under the action of the cam-driven mechanism or the linear drive mechanism. When using the cam-driven mechanism, the cam pushes the damping seat or positioning seat towards the compression return spring, bringing them closer together. This compresses and fixes the gyroscope module onto the positioning seat, switching to the north-finding mode. Once the cam moves away from the damping seat or positioning seat, the return spring causes them to move away from each other, the gyroscope module loses external pressure, detaches from the positioning seat, and switches to the vibration-damping mode. When using the linear drive mechanism, the linear movement of the linear drive mechanism allows the damping seat or positioning seat to reciprocate along the linear guide mechanism, switching between the north-finding mode and the vibration-damping mode.

[0021] Furthermore, the linear drive mechanism is a lead screw and nut mechanism, a linear motor, an electric push rod, a telescopic cylinder, a belt drive mechanism, or a gear and rack mechanism; the elastic damping component is a spring, a damping pad, or a wire rope damper.

[0022] Furthermore, the linear guide mechanism is a linear guide rail mechanism or a linear bearing mechanism, and at least two are arranged circumferentially along the reciprocating motion path.

[0023] In summary, this utility model has the advantages of reasonable structural design and the ability to switch between shock absorption mode and north-finding mode. Attached Figure Description

[0033] Figure 11 This is another structural schematic diagram of Example 3. Detailed Implementation

[0034] A shock-absorbing gyroscope device includes a base and a gyroscope module 2. A shock-absorbing seat 3 is disposed above the base. The gyroscope module 2 is mounted on the shock-absorbing seat 3 via distributed elastic shock-absorbing elements 4. A positioning seat 5 is positioned opposite the gyroscope module 2 on one side. Specifically, the positioning seat 5 can be positioned directly below, above, to the left, to the right, in front of, or behind the gyroscope module 2; that is, the gyroscope module 2 and the positioning seat 5 can be vertically opposite each other. Figure 1 As shown, they can also be set relative to each other in the horizontal direction, such as... Figure 2 As shown.

[0035] It also includes a reciprocating drive mechanism 6, the drive end of which is correspondingly arranged with the shock absorber 3, gyroscope module 2, or positioning seat 5, and can drive the corresponding shock absorber 3, gyroscope module 2, or positioning seat 5 to reciprocate along the opposite direction of the gyroscope module 2 and positioning seat 5, so that the gyroscope module 2 can be fixed to the positioning seat 5 under pressure or detached from the positioning seat 5. Specifically, regardless of whether the gyroscope module 2 and positioning seat 5 are arranged vertically or laterally opposite each other, there are three driving situations:

[0036] 1. The drive end of the reciprocating drive mechanism 6 drives the shock absorber 3 to move toward the positioning seat 5, thereby driving the gyroscope module 2 to move toward the positioning seat 5 together through the elastic shock absorber 4. After the gyroscope module 2 contacts the positioning seat 5, the shock absorber 3 continues to move toward the positioning seat 5, which will cause the elastic shock absorber 4 to undergo elastic deformation. Its elastic force is applied to the gyroscope module 2, so that the gyroscope module 2 is fixed to the positioning seat 5 under the action of the elastic force, so that the gyroscope module 2 achieves self-fixation and enters the north-finding working state.

[0037] Once the reciprocating drive mechanism 6 moves in the opposite direction, the shock absorber 3 moves away from the positioning seat 5, and the elastic shock absorber 4 gradually returns to its initial state until the gyroscope module 2 disengages from the positioning seat 5 and enters the vibration damping mode. At this time, the gyroscope module 2 is connected to the shock absorber 3 through the distributed elastic shock absorbers 4. The vibration generated by the drilling rig is transmitted to the shock absorber and then reduced by the elastic shock absorbers, thereby weakening or eliminating the vibration received by the gyroscope module, preventing the gyroscope module from being damaged by long-term vibration, and helping to extend the service life of the gyroscope module.

[0038] 2. The drive end of the reciprocating drive mechanism 6 directly drives the gyroscope module 2 to move toward the positioning seat 5 until the gyroscope module 2 is pressed tightly onto the positioning seat 5 by the reciprocating drive mechanism 6, thus fixing itself and entering the north-seeking working state; at the same time, the gyroscope module 2 will pull the elastic damping component 4 to deform during the movement, and the elastic damping component 4 will accumulate elastic potential energy.

[0039] Once the reciprocating drive mechanism 6 moves in the opposite direction, the elastic potential energy stored in the elastic damping component 4 is released, applying an elastic force to the gyroscope module 2, pulling the gyroscope module 2 to move away from the positioning seat 5. As the reciprocating drive mechanism 6 moves in the opposite direction to the farthest point, the gyroscope module 2 completely detaches from the positioning seat 5 and is connected to the damping seat 3 through the distributed elastic damping components 4, entering the shock absorption mode.

[0040] 3. The drive end of the reciprocating drive mechanism 6 drives the positioning seat 5 to move toward the shock absorber 3. After the positioning seat 5 contacts the gyroscope module 2, as the positioning seat 5 continues to move toward the shock absorber 3, the positioning seat 5 will push the gyroscope module 2 to move together. During the movement, the gyroscope module 2 pulls the elastic shock absorber 4 to produce elastic deformation. Its elastic force and the thrust of the positioning seat 5 work together on the gyroscope module 2. As the movement of the positioning seat 5 increases, the force and elastic force applied to the gyroscope module 2 also increase, thereby fixing the gyroscope module 2 under pressure on the positioning seat 5, achieving self-fixation, and entering the north-finding working state.

[0041] Once the reciprocating drive mechanism 6 moves in the opposite direction, the positioning seat 5 moves away from the shock absorber seat 3, and the elastic shock absorber 4 gradually returns to its initial state until the positioning seat 5 disengages from the gyroscope module 2 and gradually moves away from the gyroscope module 2. The gyroscope module 2 is connected to the shock absorber seat 3 through the distributed elastic shock absorbers 4 and enters the shock absorption mode.

[0042] The gyroscope device with the above structure can be directly and fixedly mounted on the drilling rig, and the switching between vibration damping mode and north-finding mode is achieved through the reciprocating drive mechanism. When the drilling rig stops drilling, the reciprocating drive mechanism 6 pressurizes the gyroscope module 2 onto the positioning seat 5, achieving self-fixation of the gyroscope module 2 and enabling north-finding operation. When the drilling rig is ready to drill, the reciprocating drive mechanism 6 disengages the gyroscope 2 from the positioning seat 5, connecting it only to the vibration damping seat 3 through the elastic damping element 4, entering vibration damping mode. This eliminates the need to frequently remove or place the gyroscope device from the drilling rig, greatly reducing workload.

[0043] To better illustrate the technical solution of this utility model, the following detailed description is provided through different embodiments.

[0044] Example 1: A shock-absorbing gyroscope device, comprising a base 1 and a gyroscope module 2, such as... Figure 3 and Figure 4 As shown, a shock-absorbing seat 3 is provided above the base 1, and the gyroscope module 2 is mounted on the shock-absorbing seat 3 by distributed elastic shock-absorbing elements 4. One side of the gyroscope module 2 has a positioning seat 5 arranged opposite to it; it also includes a reciprocating drive mechanism 6, the drive end of the reciprocating drive mechanism 6 is correspondingly arranged with the shock-absorbing seat 3, and can drive the corresponding shock-absorbing seat 3 to reciprocate along the opposite direction of the gyroscope module 2 and the positioning seat 5, so that the gyroscope module 2 can be fixed on the positioning seat 5 under pressure or detached from the positioning seat 5.

[0045] The reciprocating drive mechanism 6 includes a linear guide mechanism 61 arranged along the reciprocating motion path, and the shock absorber 3 is connected to the sliding part of the linear guide mechanism 61; the reciprocating drive mechanism 6 also includes a linear drive mechanism for driving the shock absorber 3 to move along the linear guide mechanism 61; the linear drive mechanism is arranged parallel to the linear guide mechanism 61 and has a drive part for connecting the shock absorber 3.

[0046] like Figure 3 and Figure 4 As shown, in this embodiment, the positioning seat 5 and the base 1 are integrally formed and located directly below the gyroscope module 2, meaning the reciprocating motion path is vertical. Meanwhile, as... Figure 5As shown, the shock absorber 3 has a through-hole in the middle. The gyroscope module 2 is connected to the shock absorber 3 via four elastic shock absorbers 4 evenly distributed circumferentially along the relief hole. That is, the elastic shock absorbers 4 are distributed circumferentially along the reciprocating motion path of the shock absorber 3. In this way, the elastic shock absorbers can apply a distributed force to the gyroscope module circumferentially, thereby preventing uneven force on the gyroscope module and causing it to tilt. This makes the pressure fixation between the gyroscope module and the positioning seat more stable and reliable, improving the reliability and consistency of the detection results. The elastic shock absorbers 4 are steel wire rope shock absorbers, which are mature existing products. Figure 6 As shown. Of course, in other implementations, elastic components such as springs or shock-absorbing pads can also be used as elastic damping components 4.

[0047] In this embodiment, the linear guide mechanism 61 is a vertically arranged linear bearing mechanism. The linear bearing mechanism includes a cylindrical shaft vertically arranged on the base 1 and a linear bearing slidably sleeved on the cylindrical shaft. Three linear bearings are arranged circumferentially. In specific implementations, other structural forms of linear guide mechanisms, such as linear guide rail mechanisms, can also be used, all of which can achieve linear guiding function.

[0048] In addition, the linear drive mechanism is a lead screw and nut mechanism. The input end of the lead screw and nut mechanism is connected to a drive motor through a worm gear reducer. The lead screw of the lead screw and nut mechanism is vertically and coaxially mounted on the output shaft of the worm gear reducer. The shock absorber 3 is fixedly connected to the nut of the lead screw and nut mechanism. In specific implementations, linear motors, electric push rods, telescopic cylinders, telescopic hydraulic cylinders, belt drive mechanisms, or gear and rack mechanisms can also be used as linear drive mechanisms.

[0049] In this embodiment, as Figure 3 and Figure 4 As shown, the three linear bearing mechanisms and one lead screw are evenly distributed around the circumference of the gyroscope module, which ensures the stability of the shock absorber 3 during vertical movement.

[0050] To ensure that the gyroscope module 2 maintains the same posture each time it is pressed and fixed onto the positioning base 5, i.e., that the relative positional relationship between the gyroscope module 2 and the positioning base 5 remains consistent under pressure, a corresponding positioning structure 7 is provided between the gyroscope module 2 and the positioning base 5. The positioning structure 7 is used to press and fix the gyroscope module 2 onto the positioning base 5 at a preset position. Specifically, in this embodiment, the positioning structure 7 includes at least three sets of correspondingly arranged positioning posts 71 and positioning holes 72, respectively disposed on two opposite sides of the gyroscope module 2 and the positioning base 5. The end of each positioning post 71 has a positioning cone with a gradually decreasing diameter; the maximum diameter of the positioning cone is larger than the inner diameter of the positioning hole 72, and the minimum diameter is smaller than the inner diameter of the positioning hole 72. This allows for better alignment of the positioning post and the positioning hole through the positioning cone at the end of the positioning post. Simultaneously, the guiding effect of the outer conical surface of the positioning cone allows each positioning post to more easily form a coaxial alignment with the positioning hole. By using at least three sets of corresponding positioning pins and holes, a fixed positioning plane can be defined, thus ensuring that the relative positional relationship between the gyroscope module and the positioning base remains consistent. In specific implementations, paired magnets can also be used as positioning structures 7, respectively set on two opposite sides of the gyroscope module 2 and the positioning base 5. The attraction of the paired magnets can not only keep the relative positions of the gyroscope module 2 and the positioning base 5 consistent, but also increase the reliability of their fixation.

[0051] The shock-absorbing gyroscope device of this embodiment is fixedly installed on the drilling rig. When gyroscope north-finding positioning is required, the drilling rig stops drilling. The drive motor of the lead screw and nut mechanism drives the worm gear reducer to rotate. The worm gear reducer transmits power to the lead screw, driving the lead screw to rotate. Since the shock-absorbing seat is fixedly connected to the nut of the lead screw and nut mechanism, the nut itself cannot rotate. As the lead screw rotates, it drives the nut to move the shock-absorbing seat downward. The positioning structure between the gyroscope module 2 and the positioning seat 5 is used for positioning. Specifically, the positioning cone at the end of the positioning post 71 extends into the corresponding positioning hole 72, and finally the conical surface forms a coaxial fit. At this time, the gyroscope module 2 and the positioning seat 5 are mutually fitted through three pairs of positioning posts 71 and positioning holes 72. As the shock absorber moves further down, the gyroscope module 2 can no longer move. The shock absorber will then compress the elastic shock absorber 4 downwards and apply pressure to the gyroscope module 2 through the elastic shock absorber 4, thereby fixing the gyroscope module 2 under pressure on the positioning seat 5, which facilitates subsequent north-finding positioning.

[0052] When the drilling rig needs to perform drilling operations, the drive motor rotates in the reverse direction, and the lead screw drives the shock absorber 3 to move upward until the elastic shock absorber 4 returns to its initial state. As the shock absorber 3 continues to move upward, the elastic shock absorber 4 lifts the gyroscope module 2 until the gyroscope module 2 is completely detached from the positioning seat 5. At this time, the vibration generated by the drilling operation is transmitted to the shock absorber 3 through the base, lead screw and nut mechanism, and linear guide mechanism. The vibration of the shock absorber 3 is amplified by the elastic shock absorber 4 and then transmitted to the gyroscope module 2, preventing the gyroscope module 2 from being directly exposed to a vibration environment, which helps to extend the service life of the gyroscope module 2.

[0053] In this embodiment, the reciprocating drive mechanism 6 uses a linear drive mechanism to drive the shock absorber 3. In practical engineering applications, a cam drive mechanism can also be used instead of a linear drive mechanism to drive the shock absorber 3, based on this embodiment. The cam drive mechanism includes a return spring for moving the shock absorber 3 and the positioning seat 5 away from each other, and a cam for pushing the shock absorber 3 or the positioning seat 5 toward the direction of compressing the return spring. The return spring can be installed below the shock absorber 3, for example, sleeved below the cylindrical shaft of the linear bearing mechanism. The return spring ensures that the shock absorber 3 can lift the gyroscope module 2 upwards without external force, keeping the gyroscope module 2 detached from the positioning seat 5. The cam is positioned above the shock absorber 3. During the rotation of the cam, it pushes the shock absorber 3 downwards. In this process, the shock absorber 3 first compresses the return spring until the positioning structure 7 between the gyroscope module 2 and the positioning seat 5 is fully engaged. Then, the shock absorber 3 further compresses the elastic damping element 4 and the return spring, fixing the gyroscope module 2 under pressure on the positioning seat 5, switching to the north-finding working state. When the cam rotates in the opposite direction, the shock absorber 3 loses the thrust of the cam. Under the reverse force of the return spring below, the shock absorber 3 moves upward and eventually lifts the gyroscope module 2 and separates it from the positioning seat 5, switching to the shock absorption state.

[0054] Example 2: A shock-absorbing gyroscope device, comprising a base 1 and a gyroscope module 2, such as... Figure 7 and Figure 8 As shown, a shock-absorbing seat 3 is provided above the base 1, and the gyroscope module 2 is mounted on the shock-absorbing seat 3 by distributed elastic shock-absorbing elements 4. One side of the gyroscope module 2 has a positioning seat 5 arranged opposite to it; it also includes a reciprocating drive mechanism 6, the drive end of the reciprocating drive mechanism 6 is correspondingly arranged with the positioning seat 5, and can drive the corresponding positioning seat 5 to reciprocate along the opposite direction of the gyroscope module 2 and the positioning seat 5, so that the gyroscope module 2 can be fixed on the positioning seat 5 under pressure or detached from the positioning seat 5.

[0055] In this embodiment, the positioning seat 5 is still located directly below the gyroscope module 2, meaning the reciprocating motion path is vertical. Meanwhile, the shock absorber 3 is fixedly mounted above the base 1 and has a circular clearance hole in the center. The gyroscope module 2 is connected to the shock absorber 3 via four elastic shock absorbers 4 evenly distributed circumferentially along the clearance hole; that is, the elastic shock absorbers 4 are distributed circumferentially along the reciprocating motion path of the shock absorber 3. The configuration of the elastic shock absorbers 4 in this embodiment is the same as in Embodiment 1.

[0056] In this embodiment, the reciprocating drive mechanism 6 adopts a prefabricated linear slide, which is vertically mounted on the base 1, and the positioning seat 5 is fixedly mounted on the sliding surface of the linear slide. Similar to Embodiment 1, a corresponding positioning structure 7 is provided between the gyroscope module 2 and the positioning seat 5. The positioning structure 7 is used to press and fix the gyroscope module 2 to the positioning seat 5 at a preset position. The positioning structure 7 includes at least three sets of correspondingly arranged positioning posts 71 and positioning holes 72, respectively located on two opposite sides of the gyroscope module 2 and the positioning seat 5. The end of each positioning post 71 has a positioning cone with a gradually decreasing diameter; the maximum diameter of the positioning cone is greater than the inner diameter of the positioning hole 72, and the minimum diameter is smaller than the inner diameter of the positioning hole 72. In this embodiment, three positioning posts 71 are located on the positioning seat 5, and three corresponding positioning holes 72 are located at the bottom of the gyroscope module 2.

[0057] The shock-absorbing gyroscope device of this embodiment is fixedly installed on the drilling rig. When gyroscope north-finding positioning is required, the drilling rig stops drilling and the positioning seat 5 is moved upward by the linear slide. After the positioning post 71 on the positioning seat 5 is fully engaged with the corresponding positioning hole 72, as the positioning seat 5 continues to move upward, the positioning seat 5 will push the gyroscope module 2 upward together, and cause the elastic damping member 4 to undergo elastic deformation. The reverse force of the elastic damping member 4 is applied to the gyroscope module 2, so that the gyroscope module 2 is fixed on the positioning seat 5 under pressure, which facilitates subsequent north-finding positioning.

[0058] When the drilling rig needs to perform drilling operations, the linear slide moves the positioning seat 5 downward and eventually separates it from the gyroscope module 2. This allows the gyroscope module 2 to be connected to the damping seat 3 only through the elastic damping component 4. The elastic damping component 4 can then be used to reduce the vibration transmitted from the damping seat 3, which helps to extend the service life of the gyroscope module 2.

[0059] In this embodiment, the positioning seat 5 is cantilevered and connected to the linear slide. When the gyroscope module 2 is pressed against the positioning seat 5, the pressure distribution between them may be uneven. In specific engineering applications, the linear guide mechanism in Embodiment 1 can also be used. For example, multiple cylindrical shafts and linear bearings can be arranged on the outside of the positioning seat 5. The linear bearing mechanism guides the positioning seat 5, ensuring that it remains horizontal during its up-and-down movement, thereby improving the problem of uniform force distribution between the gyroscope module 2 and the positioning seat 5. Of course, in actual engineering, the linear drive mechanism or cam drive mechanism in Embodiment 1 can also be used on the basis of the linear guide mechanism to push the positioning seat 5 upward, so that the gyroscope module 2 is fixed on the positioning seat 5 under pressure.

[0060] Example 3: A shock-absorbing gyroscope device, comprising a base 1 and a gyroscope module 2, such as... Figure 9 and Figure 10 As shown, a shock-absorbing seat 3 is provided above the base 1, and the gyroscope module 2 is mounted on the shock-absorbing seat 3 through distributed elastic shock-absorbing elements 4. One side of the gyroscope module 2 has a positioning seat 5 arranged opposite to it; it also includes a reciprocating drive mechanism 6, the drive end of the reciprocating drive mechanism 6 is correspondingly arranged with the gyroscope module 2, and can drive the corresponding gyroscope module 2 to reciprocate along the opposite direction of the gyroscope module 2 and the positioning seat 5, so that the gyroscope module 2 can be fixed on the positioning seat 5 under pressure or detached from the positioning seat 5.

[0061] In this embodiment, the gyroscope module 2 and the positioning seat 5 are arranged opposite each other in the lateral direction, that is, the reciprocating motion path is arranged in the lateral direction. The shock absorber 3 and the positioning seat 5 are fixedly installed on the base 1. The shock absorber 3 has a horizontally through-hole in the middle. The gyroscope module 2 is mounted on the shock absorber 3 through elastic shock absorbers 4 distributed circumferentially along the shock absorber hole.

[0062] In this embodiment, the reciprocating drive mechanism 6 is a cam drive mechanism and is located on the side of the gyroscope module 2 opposite to the positioning seat 5; Figure 9 As shown, the cam drive mechanism includes a cam for pushing the gyroscope module 2, a drive motor for driving the cam to rotate, and a worm gear reducer. Thus, by pushing the gyroscope module towards the positioning seat via the cam, the gyroscope module is pressurized and fixed on the positioning seat, switching to the north-finding working state. Conversely, once the gyroscope module loses the push from the cam, it will reset under the action of the elastic damping element, switching to the shock-absorbing state.

[0063] In practical implementation, a linear drive mechanism can be used instead of a cam drive mechanism. The push rod of the linear drive mechanism is positioned towards the gyroscope module 2, and the extension and retraction of the push rod is used to push the gyroscope module 2 to move laterally. For example... Figure 11As shown, the linear drive mechanism can employ telescopic cylinders, etc.

[0064] Alternatively, in a specific implementation, one side of the shock absorber 3 or positioning seat 5 can be hinged to the base 1 via a hinge shaft orthogonal to the reciprocating motion path. A return spring is also provided between the base 1 and the hinged shock absorber 3 or positioning seat 5 to keep them away from each other. The reciprocating drive mechanism 6 is a cam drive mechanism or a linear drive mechanism, located outside the hinged shock absorber 3 or positioning seat 5. The cam drive mechanism includes a cam for pushing the hinged shock absorber 3 or positioning seat 5. The linear drive mechanism has a push rod for pushing the hinged shock absorber 3 or positioning seat 5, with the push rod facing the hinged shock absorber 3 or positioning seat 5. Thus, when the reciprocating motion path is horizontal, the hinge shaft of the shock absorber or positioning seat is vertically positioned; when the reciprocating motion path is vertical, the hinge shaft of the shock absorber or positioning seat is horizontally positioned. Simultaneously, regardless of whether the shock absorber seat or the positioning seat is hinged, the return spring acts on the hinged components, causing the shock absorber seat and positioning seat to move away from each other. When the cam or push rod of the reciprocating drive mechanism pushes the hinged shock absorber seat or positioning seat inward, the shock absorber seat and positioning seat will move closer to each other, and the gyroscope module will be pressed and fixed on the positioning seat, thus switching to the north-finding mode. Once the cam or push rod of the reciprocating drive mechanism moves away, the hinged shock absorber seat or positioning seat will rotate outward under the action of the return spring, the gyroscope module will lose external pressure, detach from the positioning seat, and switch to the vibration damping mode.

[0065] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
