Description

Technical Field

[0001] The utility model belongs to the technical field of a special lifting mechanism for a steel pipe pickling tank, in particular to a special lifting mechanism for a steel pipe pickling tank. Background Art

[0002] Steel pipe pickling is a metal surface treatment process, the purpose of which is to remove impurities such as scale, rust, oil, dust, etc. on the surface of the steel pipe to improve the corrosion resistance and surface quality of the steel pipe. During the pickling process, the steel pipe is usually immersed in an acid solution, or the acid solution is sprayed on the surface of the steel pipe to produce a chemical reaction to remove these impurities.

[0003] Some existing channel steel pickling tanks put steel pipes horizontally when they are put into the pickling tank for pickling, which has a poor pickling effect. When pickling, multiple steel pipes are usually put into the pickling tank together, which will cause uneven contact between the surface of the steel pipe and the acid solution in the pickling tank, resulting in a slow pickling speed of the steel pipe, affecting the production progress. In view of this, we propose a lifting mechanism dedicated to the steel pipe pickling tank. Utility Model Content

[0004] The utility model aims to provide a lifting mechanism dedicated to a steel pipe pickling tank to solve the problems raised in the above-mentioned background technology.

[0005] In view of this, the utility model provides a lifting mechanism dedicated to a steel pipe pickling tank, comprising a bracket, a lifting device is symmetrically arranged below the bracket, a pickling tank is arranged below the bracket and between two lifting devices, and further comprising:

[0006] Two connecting parts 1, the two connecting parts 1 are respectively fixedly installed on the top of two lifting devices, the two connecting parts 1 are rotatably installed with connecting parts 2, the tops of the two connecting parts 2 are fixed to the bracket, the tops of the connecting parts 1 are fixedly installed with rubber blocks 1 and 2, the rubber block 2 is sleeved with a spring, and the bottom of the bracket is fixedly installed with a plurality of steel ropes.

[0007] In the technical solution, when working, the staff first bundles the steel pipes that need to be pickled with several steel wire ropes to ensure the stability of the several steel pipes. Then, the staff can start to extend one of the lifting devices and retract the other lifting device. When one of the lifting devices is extended, one of the lifting devices will drive one of the connecting parts to move upward. During the displacement, one of the connecting parts will rotate on one of the connecting parts and slowly tilt. At the same time, one of the connecting parts will move upward, and one end of the bracket will also move upward and slowly tilt. When one of the connecting parts rotates, it will contact one of the rubber blocks and squeeze the rubber block to deform, which can ensure that the overall tilt of the bracket is more stable.

[0008] Then, another lifting device will drive another connecting piece 1 to move downward. During the movement, another connecting piece 2 will rotate on the other connecting piece 1 and slowly tilt. At the same time, the other connecting piece 2 will move downward, and the other end of the bracket will move downward and slowly tilt. When the other connecting piece 2 rotates, it will contact one of the rubber blocks 2 and one of the springs. At this time, one of the rubber blocks 2 will be squeezed and deformed, and one of the springs will be squeezed and contracted, so that the bracket can buffer when tilting, ensuring the stability of the bracket and avoiding excessive shaking. At this time, the bracket will become tilted, and the steel wire ropes at the bottom of the bracket will tilt with the steel pipes. Then, the two lifting devices will drive the corresponding connecting piece 1 to move downward respectively. Then, the two connecting pieces 1 will drive the corresponding connecting piece 2 to move downward, and the two connecting pieces 2 will drive the bracket to move downward until the steel pipes tied by the steel wire ropes enter the pickling tank. At this time, the steel pipes enter the pickling tank in a tilted state and are completely submerged by the acid solution in the pickling tank.

[0009] Afterwards, the above operation is reversed, so that one of the lifting devices is contracted and the other lifting device is extended, so that the two ends of the bracket can be repeatedly displaced up and down, respectively, to achieve the effect of repeatedly lifting and putting down the two ends of the bracket, so that the two ends of several steel pipes can be repeatedly lifted and put down in the pickling tank, respectively, so that they can be fully contacted with the acid solution, which will wash the steel pipes more fully.

[0010] In the above technical solution, further, the plurality of steel wire ropes are linearly distributed with equal spacing.

[0011] In this technical solution, it is ensured that a plurality of steel pipes can be fixed more stably.

[0012] In the above technical solution, further, the number of the plurality of steel wire ropes is at least eight.

[0013] In this technical solution, it is ensured that a plurality of steel wire ropes can fix a plurality of steel pipes more stably.

[0014] In the above technical solution, further, the pickling tank is located directly below the plurality of steel wire ropes.

[0015] In this technical solution, it is ensured that the steel pipes bound by a plurality of steel wire ropes can enter the pickling tank.

[0016] In the above technical solution, further, the rubber block 1 and the rubber block 2 are both located between the connecting member 1 and the connecting member 2.

[0017] In the technical solution, it is ensured that the rubber block 1 and the rubber block 2 can support the tilted connecting member 2, thereby supporting the bracket and preventing the bracket from shaking too much when tilting.

[0018] In the above technical solution, further, the plurality of steel wire ropes are located between two rubber blocks.

[0019] In the technical solution, it is ensured that when the bracket is tilted, the rubber block 1 can support the bracket to prevent the bracket from shaking too much when it is tilted.

[0020] In the above technical solution, further, the rubber block 1 and the rubber block 2 are located on both sides of the hinge between the connecting member 1 and the connecting member 2.

[0021] In this technical solution, it is ensured that the second connecting member can contact the first rubber block or the second rubber block respectively when the second connecting member rotates to different angles.

[0022] In the above technical solution, further, the rubber block one and the rubber block two are tightly bonded to the connecting piece one, the bottom end of the spring is tightly welded to the top of the connecting piece one, and the top end of the spring is in contact with the connecting piece two.

[0023] In this technical solution, the structural stability of the rubber block 1 and the rubber block 2 is ensured; the structural stability of the spring is ensured.

[0024] The beneficial effects of the utility model are:
