Description

TECHNICAL FIELD

[0001] The present application relates to the field of marine navigation equipment installation, in particular to a guide hole positioning and drilling system and a positioning and drilling construction method. BACKGROUND

[0002] Commonly used navigation equipment on ships, such as fiber-optic gyrocompass systems, Beidou satellite navigation inertial navigation systems, etc., among which, fiber-optic gyrocompass systems have been widely used on ships.

[0003] The fiber-optic gyrocompass system is a navigation system based on fiber-optic gyroscopes. The fiber-optic gyrocompass system works based on the principle of fiber-optic gyroscopes. The fiber-optic gyroscope is a device that measures rotation using fiber-optic sensors in the fiber. When the ship rotates, the fiber-optic gyroscope will sense that the light beam transmitted in the fiber is affected by rotation and the phase changes. By measuring this phase change, the system can calculate the heading of the ship. The fiber-optic gyrocompass system has very high measurement accuracy and can provide stable and accurate heading data. At the same time, it can also provide navigation information such as angular velocity and acceleration to help the ship accurately steer and control its position. Compared with traditional magnetic compass systems, the fiber-optic gyrocompass system is less affected by external magnetic fields and has better stability. The fiber-optic gyrocompass system uses a combination of satellite signals and loggers to achieve alignment, orientation, attitude measurement, and positioning functions. The fiber-optic gyrocompass system is equipped with main instruments, operation units, and distribution units, and other installation equipment. The fiber-optic gyrocompass system has strong compatibility and can be compatible with or replace traditional electric compasses. It is easy to install and has complete installation equipment, is maintenance-free, has a wide range of applications, and is suitable for various ships. It can be compatible with a variety of ship navigation equipment and can replace traditional electric compasses.

[0004] Therefore, when installing the fiber-optic gyrocompass system on the ship, a suitable installation location needs to be selected, which should be away from equipment or magnetic materials that may cause magnetic field interference to ensure the accuracy and stability of the system. According to the layout and requirements of the ship, an installation site is often provided on the ship when installing the fiber-optic gyrocompass system to ensure stable installation of the system during ship operation. The specific installation method is that the fiber-optic gyrocompass system is provided with a mounting hole at the bottom, and the corresponding installation site needs to be drilled with a hole corresponding to the mounting hole, and then a screw is screwed into the mounting hole and the drilled hole to fix the fiber-optic gyrocompass system.

[0005] Therefore, during installation, the following technical problems often exist:

[0006] 1. Before drilling, the equipment to be installed needs to be placed in the installation position, and a tool should be used to mark the installation position through the installation hole. Since the equipment to be installed often has multiple installation holes, it is difficult to ensure that the distance between each mark is equal to the distance between the center point of the installation hole when marking the installation holes. This can easily cause greater installation errors when marking the installation holes of the equipment to be installed, making it difficult to align the drilled hole with the installation hole after drilling.

[0007] 2. After marking the boreholes, manual drilling is required. However, without guide holes, it's difficult to ensure the drill bit is perpendicular to the mounting surface. This results in a skewed hole relative to the mounting surface, making it impossible to properly install the screws and ensuring they are fully tightened. Please refer to [link to relevant documentation]. Figure 1 Some threaded holes can only be screwed in 1-2 turns, making it difficult to install the equipment correctly. Furthermore, because the screw is angled, tightening it can easily damage the surface of the mounting hole, sometimes even causing the screw threads to break. (See also: [link to relevant documentation]) Figure 2 The situation is shown below.

[0008] If it is necessary to ensure that all drilled holes are aligned with all mounting holes, the following method is sometimes used in the prior art; please refer to [link / reference needed]. Figure 3 This refers to placing the equipment to be installed directly on the mounting position during drilling, with the drill bit of the drilling equipment drilling directly through the mounting hole. This operation will damage the coating of the mounting hole of the equipment to be installed. Over time, rust will easily occur at the mounting screws, making it easy for the equipment to be installed to be insecure or to corrode together with the mounting position, making it difficult to disassemble, repair, and replace.

[0009] In addition, the space for installing navigation equipment on ships is small, making it unsuitable for operating large drilling equipment or for multiple people to install it at the same time, which makes installation difficult. Ships are often moored for a short time, requiring a single person to complete the installation of the navigation equipment in a short period of time. Furthermore, because the accuracy of drilling is difficult to control, repeated drilling and adjustments are required to complete the installation, which increases the difficulty of the installation work for operators and reduces work efficiency.

[0010] To address the above issues, there is an urgent need for a guide hole positioning drilling system to solve the technical problem that, during the installation of related equipment in a fiber optic gyro compass system, the drilled holes at the installation position are prone to positional deviations from the mounting holes of the equipment to be installed, or the drilled holes are not perpendicular to the installation surface and tend to tilt, thus making it difficult to install the equipment correctly. Summary of the Invention

[0011] The present application aims to provide a guide hole positioning and drilling system and a positioning and drilling construction method to solve the technical problem that when installing the related equipment in the optical fiber gyro compass system, the drilling mark on the installation hole is prone to deviation, which further causes the drilling position deviation, and the drilling hole on the installation position is difficult to be perpendicular to the installation surface and is prone to tilt, which further causes the difficulty in correct installation of the equipment to be installed.

[0014] The working principle of the present application is that the adjustable punching device determines the drilling position of the guide hole and marks the guide hole, the telescoping of the four sides of the adjustable base and the sliding of the protection structure enable the protection tube to extend into the installation hole, which not only protects the installation hole but also guides the drilling mark operation of the guide hole, so that the positioning accuracy of the punching device is high when marking the drilling hole on the installation position; then the guide drilling device drills the guide hole through the protection tube and the prepared guide hole drilling mark, and obtains the guide hole on the installation surface for installing the equipment to be installed; during installation, according to the size of the screw actually used, the screw is screwed into the guide hole and the installation hole, or the guide hole is reamed and then the screw is screwed into the hole and the installation hole, to complete the fixed connection of the equipment to be installed and the installation surface.

[0017] Due to the different sizes and positions of the mounting holes of various to-be-installed equipment, the structural design of the adjustable base enables different to-be-installed equipment to be compatible with the same set of punching device and guiding drilling device, thereby solving the technical problem that to-be-installed equipment in the same series or similar series is difficult to share the same guiding hole positioning and drilling system.

[0018] As one of the implementation manners of the detachable installation of the adjustable base and the punching device, an annular recessed table is arranged on the top surface of the protection structure corresponding to the position of the protection tube, the diameter of the annular recessed table is greater than the diameter of the protection tube, the center of the annular recessed table coincides with the central axis of the protection tube, and the side wall of the annular recessed table is provided with an internal thread; a sleeve is sleeved on the punching needle, the lower end of the sleeve is provided with an external thread, so that the lower end of the sleeve can be inserted and installed in the annular recessed table through thread cooperation.

[0019] As one of the implementation manners of the telescopic cross rod assembly, the telescopic cross rod assembly comprises a first cross rod and a second cross rod, the first cross rod is provided with a third sliding groove in the same direction as the extension direction of the first cross rod, the second cross rod has a sliding part in the same direction as the extension direction of the second cross rod, and the sliding part can slide in the third sliding groove.

[0024] An output end of the motor is fixed with a driving gear, the driving gear is connected with a driven gear in a meshing manner, one end of the driven gear towards the mounting plate is rotatably connected with the mounting plate, one end of the driven gear towards the mounting seat extends with a screw rod, an internally threaded hole corresponding to the screw rod is arranged on the mounting seat, the screw rod extends from the internally threaded hole and towards the bottom of the mounting seat, and a drill bit is detachably connected with the end of the screw rod extending from the internally threaded hole, the drill bit can perform drilling operation on the installation surface under the driving of the motor.

[0025] Specifically, the guiding drilling and tapping device provides guiding and positioning for drilling and subsequent hole expansion and tapping. When the guiding drilling and tapping device is installed on the adjustable base, the bottom surface of the mounting seat is in the same plane as the bottom surface of the adjustable base, the internal threaded hole is coaxial with the center line of the protection tube of the protection structure, and is located above the protection tube of the protection structure; the drill bit can extend into the protection tube from above the protection structure; since the extension direction of the drill bit is perpendicular to the mounting surface, and the internal threaded hole limits the position of the lead screw, the drilling direction of the drill bit does not change, which can ensure that the drilling direction of the drill bit is perpendicular to the mounting surface, and the extension direction of the drilled guide hole is also perpendicular to the mounting surface.

The light source module can provide a stable light source, usually using a laser diode or a laser, which generates a light beam that is processed and adjusted by a series of optical elements and finally input into the fiber-optic gyroscope. The fiber-optic gyroscope is the core component of the fiber-optic gyro compass system, which is composed of a fiber-optic loop and optical elements. The fiber-optic sensor in the fiber-optic loop is used to measure the phase change caused by rotation. The fiber-optic gyroscope measures the ship's heading by transmitting light into the fiber-optic loop and measuring the interference effect of the light. The receiving module is responsible for receiving the optical signal from the fiber-optic gyroscope and converting it into an electrical signal. It includes a photodetector and related circuits. The photodetector converts the optical signal into a current or voltage signal for subsequent processing and analysis. The signal processing module amplifies, filters, conditions and digitizes the received electrical signal. The signal processing module accurately processes and calculates the measurement signal to extract the ship's heading information. The control module is responsible for the stable operation of the fiber-optic gyroscope and system control. It can monitor and control the temperature, pressure and other environmental parameters of the fiber-optic gyroscope to ensure the accuracy and reliability of the system. The control module also exchanges data with other navigation systems and devices for communication.
