[0052] The second baffle 39 is a porous structure;

[0053] The bottoms of the multiple groups of support tubes 34 are all provided with rollers 40;

[0054] Put multiple groups of steel pipes on the conveying platform 8, and adjust the inclination of the conveying platform 8 by extending or contracting multiple groups of first hydraulic cylinders 9, so that the multiple groups of steel pipes roll to the right, and turn on the second motor 13 to drive the second shaft 10 to rotate, and adjust the distance between the first baffle 11 and the conveying platform 8 to keep a gap that only allows one group of steel pipes to pass through, and turn on multiple groups of vibration motors 12 to vibrate the first baffle 11 to prevent the steel pipes from being blocked on the left side of the first baffle 11, so that the steel pipes can be neatly arranged on the right side of the conveying platform 8, turn on the first motor 6, and drive through the two groups of first shafts 2 to make the multiple groups of first sprocket wheels 3 respectively contact the two groups of first chains 4 The meshing transmission causes the multiple groups of first conveying frames 5 to move, and the multiple groups of steel pipes on the right side of the conveying platform 8 are taken off one by one through the multiple groups of first conveying frames 5, and are sent to the material basket 15. The third motor 20 is turned on, and the multiple groups of second sprocket wheels 17 are driven to drive the multiple groups of second chains 18. The steel pipes in the material basket 15 are stirred from left to right through the multiple groups of second conveying frames 19, so that the multiple groups of steel pipes are rolled in the material basket 15. At the same time, the third rotating shaft 16 is repeatedly rotated forward and reversely through the transmission mechanism, and the multiple groups of second hydraulic cylinders 26 are contracted to attach one end of the two groups of spline shafts 29 to the front end and the rear end of the first rotating shaft 2 on the right side, respectively. At the same time, the multiple groups of first springs 28 are contracted, and then as The rotation of the first rotating shaft 2 on the right side causes one end of the two groups of spline shafts 29 to be respectively inserted into the spline holes 30 at the front end and the rear end of the first rotating shaft 2. Then, as the first rotating shaft 2 rotates, the spline shaft 29 drives the second gear 25 to rotate, and then the second gear 25 is meshed with the first gear 24 to drive the third rotating shaft 16 to rotate, so that the material basket 15 rises. Then, the first motor 6 runs in the reverse direction to make the material basket 15 fall and reset, and the above steps are repeated repeatedly. When the material basket 15 rises, the elasticity of the multiple groups of second springs 36 causes the multiple groups of pistons 33 to slide downward, so that the multiple groups of support tubes 34 suck the pickling liquid into the multiple groups of conveying cylinders 31, and then in the multiple groups of When the material basket 15 descends, the bottoms of the multiple groups of support tubes 34 are supported in the pickling tank, so that the multiple groups of pistons 33 slide upward, and the pickling liquid is discharged into the drainage pipe of the material basket 15, and then the pickling liquid is sprayed into the multiple groups of steel pipes through the multiple groups of spray holes on the material basket 15 to improve the pickling effect. After the pickling is completed, the material basket 15 is raised to tilt the material basket 15 to the left, and the third motor 20 runs in the reverse direction to make the multiple groups of second conveying frames 19 stir the steel pipes to the left. At the same time, the multiple groups of fourth motors 38 are turned on to rotate the multiple groups of winding shafts 37 to loosen the wire rope. Then the second baffle 39 is opened to discharge the steel pipes stirred to the left, thereby improving the practicality of the equipment.

[0055] The main functions achieved by the present invention are: improving pickling effect, improving equipment automation, and improving equipment linkage;

[0056] 1. Improve the pickling effect: by transporting the steel pipes one by one to the pickling tank, the steel pipes are turned over by the stirring mechanism, and the pickling liquid is sprayed onto the steel pipes at the same time, so as to improve the pickling effect;

[0057] 2. Improve equipment automation: The pickled steel pipes are automatically discharged through the stirring mechanism and the discharging mechanism, thus improving the automation of the equipment;

[0058] 3. Improve the linkage of equipment: through the transmission mechanism, a group of power sources can realize the transportation and discharge of steel pipes, thereby improving the linkage of equipment.

[0059] The installation method, connection method or setting method of a steel pipe loading platform for a closed automatic pickling line of the present invention are all common mechanical methods, and can be implemented as long as they can achieve their beneficial effects; the diameter of the second gear 25 is larger than the first gear 24, and when the first motor 6 runs in the reverse direction, the two groups of first chains 4 only need to run in the reverse direction for a short section, which will not affect the multiple groups of steel pipes on the first conveying racks 5; the first motor 6, the first hydraulic cylinder 9, the vibration motor 12, the third motor 20, the second hydraulic cylinder 26 and the fourth motor 38 of the steel pipe loading platform for a closed automatic pickling line of the present invention are purchased on the market, and technicians in the industry only need to install and operate them according to the accompanying instruction manual, without the need for creative labor by technicians in this field.

[0060] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
