Description

Technical Field

[0001] This utility model relates to the field of gyroscope north-finding instrument technology, specifically to a gyroscope mounting plate structure and a north-finding instrument. Background Technology

[0002] An inertial measurement unit (IMU) using gyroscopes and accelerometers as sensing elements is a completely autonomous system. It does not rely on any external information and does not emit heat or energy, making it stealthy and capable of all-weather operation. It enables omnidirectional, autonomous, and rapid orientation determination and can serve as an orientation reference for observation, target aiming, and navigation systems, as well as for underground operations such as tunnels and mines.

[0003] North-finding instruments typically use gyroscopes as the sensitive measuring component for the Earth's rotation angular rate. By combining the Earth's rotational velocity component measured by the gyroscope with the carrier's tilt angle measured by the accelerometer, the carrier's azimuth angle—the angle between the carrier's reference axis and true north—is calculated. This is primarily used for initial alignment and direction control, field reconnaissance orientation, determining firing direction, platform azimuth reference calibration, and orientation finding in underground construction. The accuracy of a north-finding instrument largely depends on the accuracy of the gyroscope.

[0004] Currently, the most widely used gyroscope north-finding instrument in China is the flexible gyroscope. Flexible gyroscopes are mechanical gyroscopes, containing a high-speed rotating motor, bearings, and a flexible support for key components. Existing technology presents several technical challenges when different precision gyroscopes are required for the same product model. These challenges include the need to re-process an adapter mounting plate, affecting testing or experimental progress; the requirement to drag the old gyroscope along when replacing it, hindering testing operations; and the fact that the original mounting plate only supports a single gyroscope model, making it impossible to quickly switch to other models. Utility Model Content

[0005] The purpose of this utility model is to provide a gyroscope mounting plate structure and a north finder, which can effectively solve the technical problems in the prior art where different precision gyroscopes are required in the same model of product, resulting in inconvenient gyroscope fixing and replacement, and poor compatibility.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0007] A gyroscope mounting plate structure includes a gyroscope bracket for mounting on a north-finding instrument turntable, the gyroscope bracket being used to mount the gyroscope;

[0008] The gyroscope support has several mounting holes, which are equidistantly distributed on both sides of the center line of the gyroscope support. A shock-absorbing pad is provided between the gyroscope and the gyroscope support, and the gyroscope and the gyroscope support are fixed together by screws passing through the mounting holes.

[0009] Furthermore, a limit mounting slot is provided on the turntable, and the gyroscope bracket is fixedly installed in the limit mounting slot.

[0010] Furthermore, the turntable is provided with a first mounting hole that communicates with the limiting mounting groove, and the bottom of the gyroscope bracket is provided with a second mounting hole corresponding to the first mounting hole. The second mounting hole is a threaded hole, and the gyroscope bracket and the turntable are fixedly connected by a screw that passes through the first mounting hole and is threaded to the second mounting hole.

[0011] Furthermore, the gyroscope support is equipped with weight-reducing holes.

This utility model also includes a gyroscope mounting plate structure mounted on the turntable, and an inclination plate is also provided on the turntable.

[0015] The base is also equipped with a coupling that connects to the drive motor and the turntable.

[0016] Furthermore, a first photoelectric switch is installed on the base, and a sensing screw is installed on the lower surface of the turntable.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] In practical use, this invention features a gyroscope bracket with several mounting holes evenly spaced on both sides of the bracket's centerline. A shock-absorbing pad is placed between the gyroscope and the bracket, and the gyroscope and bracket are secured together by screws passing through the mounting holes. The gyroscope bracket incorporates multiple mounting hole sizes, with various gyroscope mounting holes pre-installed on the mounting plate, supporting direct installation and switching between different gyroscope models. Furthermore, this invention eliminates the need for additional gyroscope bracket fabrication; gyroscope models can be changed in real-time with simple adjustments.

[0033] Example 1

[0034] See Figures 1-4 This embodiment discloses a gyroscope mounting plate structure, including a gyroscope bracket 102 for mounting on a north-finding instrument turntable 101, wherein the gyroscope bracket 102 is used to mount a gyroscope 103;

[0035] The gyroscope bracket 102 is provided with a plurality of mounting holes 104, which are arranged in a longitudinal and transverse pattern at equal intervals on both sides of the center line of the gyroscope bracket 102; a shock-absorbing pad 105 is provided between the gyroscope 103 and the gyroscope bracket 102, and the gyroscope 103 and the gyroscope bracket 102 are fixed by screws passing through the mounting holes 104.

[0036] In practical use, this embodiment features several mounting holes 104 on the gyroscope bracket 102, equidistantly distributed along both sides of the centerline of the gyroscope bracket 102. A shock-absorbing pad 105 is placed between the gyroscope 103 and the gyroscope bracket 102, and the gyroscope 103 and gyroscope bracket 102 are fixed together by screws passing through the mounting holes 104. The gyroscope bracket 102 incorporates multiple sizes of mounting holes, and the mounting plate has pre-set mounting holes for various sizes of gyroscopes 103, supporting direct installation and switching between different models of gyroscopes 103. Furthermore, this invention eliminates the need for additional machining of new gyroscope brackets 102; real-time replacement of gyroscope 103 models is achieved through simple adjustments. This instant switching of gyroscope 103 models significantly shortens replacement time and improves testing efficiency. The absence of redesigned or machined mounting plates reduces hardware costs, supports flexible adaptation to multiple gyroscope 103 models, and enhances equipment versatility.

[0037] Furthermore, a limiting mounting groove 106 is provided on the turntable 101, and the gyroscope bracket 102 is fixedly installed in the limiting mounting groove 106. In this embodiment, the limiting mounting groove 106 enables rapid positioning of the gyroscope bracket 102 and provides lateral support for the gyroscope bracket 102, effectively preventing the gyroscope bracket 102 from tipping over.

[0038] In this embodiment, the size and arrangement of several mounting holes 104 are adapted to the direct mounting of at least two different models of gyroscopes 103.

[0039] Furthermore, in actual use, the mounting hole 104 includes at least two combinations of circular holes, rectangular holes, and polygonal holes, and the spacing between each hole is set according to the dimensional tolerance range of the target gyroscope 103.

[0040] Furthermore, the gyroscope support 102 is made of aluminum alloy.

[0041] As an alternative, the gyroscope bracket 102 is made of a lightweight composite material comprising a carbon fiber reinforced resin matrix with a thickness of 70%-90% of the original mounting plate thickness.

[0042] Furthermore, in some preferred embodiments, the edge of the mounting hole 104 is provided with anti-slip texture, which is a sawtooth or wavy structure, to increase the friction when the gyroscope 103 is installed.

[0043] The turntable 101 is provided with a first mounting hole 104 that communicates with the limiting mounting groove 106. The bottom of the gyroscope bracket 102 is provided with a second mounting hole 104 corresponding to the first mounting hole 104. The second mounting hole 104 is a threaded hole. The gyroscope bracket 102 and the turntable 101 are fixedly connected by a screw that passes through the first mounting hole 104 and is threaded to the second mounting hole 104.

[0044] In practical use, using screws for connection results in low assembly efficiency. Therefore, in some preferred implementations, a quick-locking mechanism can be used for rapid installation. The quick-locking mechanism includes a spring pin and a buckle, which is used to achieve one-click fixation after the gyroscope 103 is inserted into the corresponding hole. Its specific structure can adopt the quick-locking mechanism in the prior art, and its specific structure will not be described in detail here.

[0045] Furthermore, the gyroscope support 102 is provided with weight reduction holes 107. The weight reduction holes 107 can effectively reduce the overall weight of the gyroscope support 102.

[0046] Among them, the shock-absorbing pad 105 is made of rubber or silicone material.

[0047] In addition, this embodiment also discloses a north-finding instrument, including a base 108, a turntable 109 disposed on the base 108, a drive motor 112 disposed on the base 108 and connected to the turntable 109, and a turntable 101. The north-finding instrument also includes the gyroscope 103 mounting plate structure described above, and an tilting plate 110 is also disposed on the turntable 101.

[0048] Furthermore, the base 108 is also provided with a coupling 110 that is connected to the drive motor 112 and the turntable 109.

[0049] The base 108 is equipped with a first photoelectric switch, and the lower surface of the turntable 101 is equipped with a sensing screw.

[0050] Furthermore, a pressure sensor array is provided on the gyroscope bracket 102. The pressure sensor array is used to detect whether the gyroscope 103 is installed in place. The pressure sensor array is connected to an LED indicator via a controller, and the LED indicator is used to indicate the operating status.

[0051] In actual use, a box 113 is provided on the base 108.

[0052] Furthermore, in some preferred embodiments, the limiting mounting groove 106 has a T-shaped or dovetail-shaped structure, and the bottom of the gyroscope bracket 102 matches the limiting mounting groove 106. In actual use, the gyroscope bracket 102 is installed by side-mounting and sliding in, and then the gyroscope bracket 102 is fixed. This setting can ensure greater stability during installation, avoid tipping during installation, and reduce the installation difficulty of the gyroscope bracket 102. More importantly, after installation, the gyroscope bracket 102 is more stable, further improving the anti-tipping performance of the gyroscope bracket 102.

[0053] Although preferred embodiments of the present invention have been described, those skilled in the art, upon learning the basic inventive concept, can make other changes and modifications to these embodiments. Therefore, the appended claims are intended to be interpreted as including the preferred embodiments as well as all changes and modifications falling within the scope of the present invention.
