Description

Pilot hole positioning drilling system and positioning drilling construction method

technical field

The invention relates to the field of marine navigation equipment installation, in particular to a guide hole positioning drilling system and a positioning drilling construction method.

Background technique

Commonly used navigation equipment on board such as fiber optic gyro compass system, Beidou satellite navigation inertial navigation system, etc., among them, fiber optic gyro compass system has been widely used on ships.

Fiber optic gyro compass system is a navigation system based on fiber optic gyroscope. The fiber optic gyro compass system works based on the principle of fiber optic gyroscope. A fiber optic gyroscope is a device that measures rotation using a fiber optic sensor in an optical fiber. When the ship rotates, the fiber optic gyroscope will sense the phase change of the light beam transmitted in the fiber due to the rotation. By measuring this phase change, the system can calculate the ship's heading. The fiber optic gyro compass 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 ships perform precise steering and position control. Compared with traditional magnetic compass System, the fiber optic gyro compass system has less interference to the external magnetic field and has better stability. The fiber optic gyro compass system adopts the integrated navigation technology with satellite signals and speed logs to achieve alignment, orientation, attitude measurement, positioning and other functions; the standard configuration of the fiber optic gyro compass system is mainly composed of main instruments, operating units and distribution units waiting to be installed , The fiber optic gyro compass system has strong compatibility and can be compatible or replace the traditional gyro compass; easy to install; complete supporting equipment to be installed, maintenance-free, wide application range, suitable for various ships, compatible with a variety of ship navigation equipment, and can replace traditional Gyro compass.

Then, when installing the fiber optic gyro compass system on a ship, it is necessary to choose a suitable installation location, which should be far away from equipment or magnetic materials that may cause magnetic field interference, so as to ensure the accuracy and stability of the system, according to the layout and requirements of the ship , when installing the fiber optic gyro compass system, there are usually installation positions on the ship to ensure the stable installation of the system during the operation of the ship. Drill holes corresponding to the mounting holes, and then screw screws into the mounting holes and the drilled holes to fix the fiber optic gyro compass system.

Then in the process of installation, there are often the following technical problems:

1. Before drilling, it is necessary to place the equipment to be installed on the installation position, and use a tool to make drilling marks on the installation position through the installation holes. Since the equipment to be installed often has multiple installation holes, when marking, Since the equipment to be installed is easy to move, it is difficult to ensure that the distance between each mark is equal to the distance between the center points of the installation holes. When drilling marks for the installation holes of the equipment to be installed, it is easy to cause greater installation errors. After drilling, it is difficult to align the drilling hole with the installation hole;

2. After the drilling marks are done, manual drilling is required. During manual drilling, there is no guiding positioning hole, and it is difficult to ensure that the drilling tool is perpendicular to the installation surface of the installation position, so the drilling is skewed relative to the installation surface. , then the screws cannot be installed correctly, and it is difficult to ensure that the screws are screwed in place. Please refer to Figure 1. Some threaded holes can only be screwed into 1-2 threads of the drilled hole, which makes it difficult to install the equipment to be installed correctly. At the same time, because the screw is crooked, it is easy to damage the surface of the mounting hole of the device to be installed when screwing the screw, and sometimes even make the screw rotten, as shown in Figure 2.

If it is necessary to ensure that all the drilling holes are aligned with all the mounting holes one by one, the following method is sometimes used in the prior art, please refer to Figure 3, that is, the equipment to be installed is directly placed on the installation position when drilling, and the drilling equipment The drill bit directly drills the installation position through the installation hole, so this operation will damage the coating layer of the installation hole of the equipment to be installed. The installation is not firm or it is rusted together with the installation position, making it difficult to disassemble, repair and replace.

In addition, the installation space of ship navigation equipment is small, which is not suitable for large-scale drilling equipment operation, nor is it suitable for multiple people to install and operate at the same time, which makes installation difficult; and the time for ships to berth is often short, requiring a single person to navigate in a short time. The equipment installation is completed; and because the drilling accuracy is difficult to control, repeated drilling and adjustments are required to complete the installation, which increases the difficulty of the operator's installation work and reduces the work efficiency.

In view of the above problems, there is an urgent need for a pilot hole positioning drilling system, which is used to solve the problem of positional deviation between the drilling holes opened on the installation position and the installation holes of the equipment to be installed when the related equipment in the fiber optic gyro compass system is installed, or the drilling holes are difficult to be vertical Because the installation surface is easy to tilt, which leads to the technical problem that the equipment to be installed is difficult to install correctly.
