[0012] Beneficial effects

[0013] In this utility model, a clamping device is adopted, which is a clamping arm made of high-strength alloy steel. Its opening and closing action is controlled by an adjusting shaft. The inner side of the clamping arm is equipped with an adjustable rubber pad, which can effectively increase the friction with the circular pipe, ensuring that the circular pipe is stable and does not shift during the connection process, and also avoid damage to the outer wall of the circular pipe.

[0014] In this invention, a laser rangefinder and an electric rod are used. The laser rangefinder can accurately measure the relative positional deviation between two circular pipe flanges to be connected. After the data is transmitted to the control system, the fine-tuning motor in the base automatically adjusts the axial and radial positions of the circular pipe according to the instructions of the electric rod, so as to achieve high-precision alignment of the flange.

[0023] The specific embodiments of this utility model are described below with reference to the accompanying drawings. Specific Implementation Example 1:

[0025] Reference Figure 1-5 This utility model provides a flange connection device for installing large circular pipes, including a base 1. An electric rod 2 is mounted on the top of the base 1. A fine-tuning motor and a controller are located inside the base 1. The fine-tuning motor and the electric rod 2, as well as the controller and the electric rod 2, are electrically connected. A connecting rod 3 is mounted on the top of the electric rod 2, and the electric rod 2 and the connecting rod 3 are connected by welding. A moving groove is located on the top of the base 1, and the electric rod 2 is located inside the moving groove. A clamping assembly 4 is mounted on the top of the connecting rod 3. The clamping assembly 4 includes an arc-shaped clamping arm 401, an adjusting shaft 402 at the bottom end of the clamping arm 401, and a rubber pad 403 on the inner wall of the clamping arm 401. Laser rangefinders 5 are mounted on both sides of the top of the clamping assembly 4. The laser rangefinders 5 are connected to the clamping arm 401 by bolts and are electrically connected to the controller. The laser rangefinders 5 can accurately measure distances between the clamping arm and the controller. The relative positional deviation between the flanges 7 and two circular pipes 6 to be connected is measured. After the data is transmitted to the control system, the fine-tuning motor in the base 1 automatically adjusts the axial and radial positions of the circular pipes 6 according to the command electric rod 2 to achieve high-precision centering of the flanges 7. Laser rangefinders 5 are provided on the top of both sides of the clamping arm 401. The circular pipe 6 is located at the top center of the clamping assembly 4. One end of the circular pipe 6 is provided with a flange 7, which is embedded in the circular pipe 6. The circular pipes 6 are horizontally connected to each other through the flanges 7. The clamping assembly 4 is used, and the clamping arm 401 is made of high-strength alloy steel. Its opening and closing action is controlled by the adjusting shaft 402. The inner side of the clamping arm 401 is equipped with an adjustable rubber pad 403, which can effectively increase the friction with the circular pipe 6, ensure that the circular pipe 6 is stable and does not shift during the connection process, and avoid damage to the outer wall of the circular pipe 6. Specific Implementation Example 2:

[0027] Reference Figure 1The bolt installation between flanges 7 is too slow by manual operation. A bolt tightening assembly can be set up, including an electric torque wrench and a bolt delivery rail. The electric torque wrench can automatically complete the bolt tightening operation according to the preset torque value, ensuring that the tightening force of each bolt is uniform and consistent, avoiding the problem of poor sealing of flange 7 due to uneven bolt tightening. The bolt delivery rail can automatically deliver the bolts to the installation position, improving the efficiency of bolt installation.
