[0002] In order to remove surface oxides and rust and ensure product quality, steel pipes need to be pickled during the production process.

[0003] However, as shown in the seamless steel pipe pickling device disclosed in application number 202120073812.4, in conventional pickling devices, steel pipes are mostly stacked for pickling. This stacking method makes it easy for the steel pipes to be incompletely pickled, especially the contact parts between the steel pipes are prone to blocking the pickling solution. This phenomenon needs to be improved. Utility Model Content

[0026] Reference Figures 1-4 According to an embodiment of the present invention, a steel pipe pickling tank includes a tank body 11, wherein the tank body 11 is provided with an upward-opening cavity 12, and the cavity 12 is filled with pickling liquid, which can perform pickling treatment on the steel pipes entering the cavity 12.

[0027] To facilitate the pickling of steel pipes, a lifting outer frame 13 is slidably connected inside the tank cavity 12, and multiple support plates 14 are arranged left and right inside the lifting outer frame 13. Multiple arc-shaped grooves 15 for accommodating steel pipes are provided on the upper side of the support plates 14, and the arc-shaped grooves 15 are arranged at equal distances front and back. Each support plate 14 is connected by a crossbar 16. The lifting outer frame 13 also includes an adjustment mechanism for controlling the left and right position of the crossbar 16, and several partition plates 17 are arranged left and right on the lifting outer frame 13.

[0028] When the steel pipe is placed inside the lifting outer frame 13, it will be placed in the arc-shaped groove 15 on at least two of the support plates 14. Specifically, the steel pipe will be arranged in front and back and left and right in the lifting outer frame 13, and the left and right groups of steel pipe will be separated by the partition plate 17. After the lifting outer frame 13 is immersed in the groove cavity 12 and pickling is performed, the crossbar 16 and the support plate 14 can move left and right, while the steel pipe will remain stationary under the abutment of the partition plate 17 and the left and right sides of the lifting outer frame 13 (or the steel pipe will move laterally with an amplitude smaller than that of the support plate 14). This is to make the support plate 14 move laterally relative to the steel pipe so as to avoid the steel pipe contacting the part of the arc surface inside the arc-shaped groove 15 and blocking the pickling solution, so as to affect the pickling effect.

[0029] In addition, a lifting system for controlling the lifting of the outer frame 13 is included. In this embodiment, the lifting system includes two mounting plates 18 mounted on the groove 11 and distributed on the left and right. Each of the two mounting plates 18 is equipped with a wheel frame 19, and a drum is rotatably connected inside the wheel frame 19. A rope with its end connected to the lifting frame 13 is wound inside the drum, and a lifting motor 20 for driving the drum to rotate is also mounted on the wheel frame 19.

[0030] In order to make the lifting outer frame 13 rise and fall stably, the bottom surface of the cavity 12 is provided with a sliding rod that extends upward through the lifting outer frame 13. The sliding rod is provided with four rods arranged in an array and located at the bend of the lifting outer frame 13.

[0031] When the lifting motor 20 is powered on, the lifting motor 20 will drive the drum to rotate to release or rewind the rope, thereby causing the lifting frame 13 to rise and fall. When the lifting frame 13 is at its lowest point, the steel pipe inside the lifting frame 13 will undergo pickling. When the lifting frame 13 is at its highest point, the steel pipe will be removed from the pickling solution to facilitate loading and unloading by workers.

[0032] The crossbar 16 extends laterally to the left and right sides of the lifting outer frame 13 and can slide left and right relative to the lifting outer frame 13 (the lifting outer frame 13 can only move up and down). The control mechanism includes a spring plate 21 installed at the left end of the crossbar 16, and a spring is also installed on the left side of the spring plate 21. A control plate 22 is installed at the right end of the crossbar 16, and a cylinder 23 is installed at the right end of the groove 11. The piston rod in the cylinder 23 extends into the groove cavity 12 and can be directly opposite the control plate 22.

[0033] When the lifting outer frame 13 is at its lowest position, the controlled plate 22 can be pushed by the cylinder 23, causing the crossbar 16 and the support plate 14 to move to the left. At this time, the steel pipe located on the support plate 14 will remain relatively stationary on the left and right sides of the lifting outer frame 13 on the partition plate 17 (or undergo a lateral movement with an amplitude smaller than that of the crossbar 16). When the piston rod retracts, the spring abutting against the left side of the groove cavity 12 will drive the support plate 14 and the crossbar 16 to move to the right through the spring plate 21, thereby controlling the position of the support plate 14 and improving the pickling effect of the steel pipe.

[0034] To prevent the spring from scratching the left wall of the cavity 12 when the lifting frame 13 is raised or lowered, two horizontal plates are integrally formed on the left side of the spring plate 21, which are distributed front and back. Slide plates are slidably connected to the horizontal plates. A noise reduction plate 24 is integrally formed on the left end of the two slide plates. The left end of the spring is connected to the right side of the noise reduction plate 24, and a roller 25 is attached to the left side of the cavity 12.

[0035] By setting the rollers 25, noise reduction and scratch prevention are achieved when the lifting frame 13 moves up and down. During the lifting process of the lifting frame 13, the noise reduction plate 24 will only move up and down.

[0036] In addition, the noise reduction plate 24 can also be configured to slide vertically within the cavity 12 to achieve the same technical purpose.

[0037] Furthermore, the crossbar 16 is provided with two crossbars distributed front and back, and the two crossbars 16 are connected to a spring plate 21 and a controlled plate 22.

[0038] It should be noted that when the piston rod is at its rightmost position, the left end of the piston rod will be separated from the control plate 22 and there will be a certain distance between them, so as to avoid the control plate 22 pressing on the piston rod during the descent of the lifting outer frame 13, which would cause equipment malfunction.

[0039] In order to allow the position of the partition plate 17 to be adjusted according to the length of the steel pipe, the partition plate 17 is installed by means of multiple mounting slots distributed on the left and right sides inside the lifting frame 13. The partition plate 17 is inserted into the mounting slot. The partition plate 17 does not detach when the lifting frame 13 is raised or lowered by its own weight and the friction between the partition plate 17 and the mounting slot. It can only detach from the mounting slot when manually moved by the operator.

[0040] The partition plate 17 needs to be installed at a certain distance from the support plate 14 to avoid the support plate 14 and the crossbar 16 hitting the partition plate 17 when they move laterally.

[0041] The distribution location and density of the support plates 14 shown in the figure are for illustrative purposes only.

[0042] The above description is only a specific embodiment of the present utility model, but the technical features of the present utility model are not limited thereto. Any changes or modifications made by those skilled in the art within the scope of the present utility model are covered by the patent scope of the present utility model.
