DETAILED DESCRIPTION

[0022] The directional terms mentioned in the following embodiments, such as "up", "down", "left", and "right", are only for reference to the accompanying drawings. Therefore, the directional terms used are for illustration and not for limiting the invention of this utility model.

[0023] like Figures 1-3 As shown, a furnace tube row alignment device includes a first positioning seat 1 and a second positioning seat 2. The first positioning seat 1 is provided with multiple guide grooves 12 and multiple first positioning grooves 11 for positioning one side of the furnace tube. The second positioning seat 2 is provided with a guide block 22 and multiple second positioning grooves 21 for positioning the other side of the furnace tube. After the first positioning seat 1 and the second positioning seat 2 are engaged, the first positioning grooves 11 and the second positioning grooves 21 face each other. The guide block 22 is slidably connected to the guide groove 12. The extension direction of the first positioning groove 11 is parallel to the extension direction of the second positioning groove 21, and the extension direction of the guide groove 12 is perpendicular to the extension direction of the first positioning groove 11. By securing the furnace tube with the first positioning seat 1 and the second positioning seat 2 respectively, and then moving the first positioning seat 1 or the second positioning seat 2 to move the furnace tube radially, the position of the furnace tube is adjusted and corrected, making the gap of the furnace tube row more accurate and better ensuring the parallelism between each furnace tube. During the adjustment process, the guide block 22 and the guide groove 12 improve the ease of operation, accuracy and efficiency.

[0024] Furthermore, an adjusting rod 4 is rotatably connected to the first positioning seat 1 via a rotating seat 41, and a threaded seat 3 is installed on the second positioning seat 2. The threaded seat 3 is provided with a threaded groove 5, and the adjusting rod 4 is provided with an adjusting thread. A slot is provided at the end of the second positioning seat 2, and the threaded seat 3 is a Z-shaped plate. The threaded seat 3 is inserted into the slot and is limited in the radial direction of the furnace tube. After the first positioning seat 1 and the second positioning seat 2 are engaged, the adjusting thread engages with the threaded groove 5. To improve its structural strength and stability, ribs can be added to the threaded seat 3. After the first positioning seat 1 and the second positioning seat 2 are docked, the adjusting thread engages with the threaded groove 5. By rotating the adjusting rod 4, the first positioning seat 1 can move laterally relative to the second positioning seat 2. The movement process is controllable and highly accurate.

[0025] Furthermore, a gap is left between the threaded seat 3 and the slot to form a locking positioning groove 10. A locking positioning plate can be inserted into the locking positioning groove 10. The upper end of the locking positioning plate extends into the first positioning seat 1, thereby forming a lateral limit on the first positioning seat 1.

[0026] Furthermore, in this embodiment, a polygonal adjustment block 6 is fixedly connected to the end of the adjustment rod 4.

[0027] Further, the side of the first positioning seat 1 and the side of the second positioning seat 2 are fixedly connected with a limiting guide plate 7, the limiting guide plate 7 is provided with a guide limiting groove 71, a turnover limiting rod 8 for preventing the first positioning seat 1 and the second positioning seat 2 from overturning is inserted into the guide limiting groove 71, the turnover limiting rod 8 is slidingly connected with the guide limiting groove 71, and the extension direction of the guide limiting groove 71 is parallel to the extension direction of the guide groove 12.

[0028] Further, the turnover limiting rod 8 is threadedly connected with a limiting nut 9, the limiting nut 9 is installed on the upper side, and the gravity is combined to realize the overturning of the adjusting rod 4 and prevent the first positioning seat 1 and the second positioning seat 2 from being separated due to the reaction force, the limiting nut 9 is installed on the upper side and the lower side, and the pipe can be clamped to improve the stability.

[0029] Further, the first positioning groove 11 and the second positioning groove 21 are circular arc-shaped, better fit the outer surface of the furnace pipe, reduce the friction and damage during positioning, and protect the integrity of the furnace pipe.

[0030] Further, the guide block 22 is square and the corners are transitioned with round corners, so that the sliding of the guide block 22 in the guide groove 12 is more stable, the round corner transition reduces the friction and wear, and the service life of the device is prolonged.

[0031] In use, if the furnace pipe is arranged horizontally and the axis direction is the front-back direction, the first positioning seat 1 is on the upper side, the second positioning seat 2 is on the lower side, the first positioning groove 11 is arranged downward, the second positioning groove 21 is arranged upward, and the first positioning groove 11 and the second positioning groove 21 are arranged in the front-back direction.
