Description

Technical Field

[0001] The utility model relates to the technical field of steel coil feeding, in particular to a coil feeding device for steel pipe production. Background Art

[0002] The coils used in steel pipe production usually refer to steel raw materials supplied in coils. This raw material is finally made into steel pipes after a series of processing steps. The selection and processing of coils are crucial to the quality and production efficiency of steel pipes. In the process of steel pipe production, a loading device is required to lift the rolled steel coils to the processing device for rolling, welding or forming. Commonly used lifting and loading devices usually use steel cables to pass through the middle hole of the steel coil, and overlap and fix the steel cables at both ends, then use a lifting motor to lift the steel coil, and then move it to the processing device for processing.

[0003] However, when the traditional lifting and loading device uses a steel cable to lift the steel coil, due to the large force on both ends of the steel cable and the two sides of the inner diameter of the steel coil, it is easy to cause deformation on both sides of the inner wall of the steel coil, affecting the subsequent processing and manufacturing. In order to solve this problem, a common way is to fix a lifting rod at one end of the steel cable, and pass the lifting rod through the middle of the steel coil to avoid deformation on both sides of the steel coil during the lifting process. However, in the actual production process, this method is difficult for workers to pass the lifting rod through the steel coil because the lifting rod needs to bear the heavy weight of the heavy steel coil. At the same time, the lifted steel coil may also rotate and slip on the lifting rod, and its stability is poor. Utility Model Content

[0023] like Figure 1 - Figure 6 As shown, a coil material feeding device for steel pipe production in the utility model is similar in structure to the existing coil material feeding device for steel pipe production. The main improvement of the utility model is to reduce the extrusion deformation of the inner ring of the steel coil caused during the lifting process and improve the quality of the steel coil product. Figures 1 to 6 As shown, when the coil material feeding device for steel pipe production in the utility model is in use, the two steel coil hanging rods 5 are pulled outward in the lifting slider 3 by the pulling plate 6, and then the whole feeding device is moved to the position of the steel coil through the moving mechanism, and the two lifting screws 4 are driven to rotate by the driving mechanism, and the two lifting sliders 3 are moved to the inner diameter position of the steel coil by cooperating with the threaded holes 301, and then the pulling plate 6 and the steel coil hanging rod 5 are moved to the other lifting slider 3 and connected with the connecting assembly, and then the two lifting screws 4 are driven again by the driving mechanism. The lowering slider 3 is driven upward in the lifting slide 201, and lifts the steel coil strung on the steel coil hanging rod 5 to a certain height, completing the lifting operation of the steel coil, and then moves the steel coil to the top of the processing equipment through the moving mechanism to complete the loading operation of the steel coil.

The moving pulleys 9 are installed at both ends of the moving base 8 through bearings, which facilitates the movement of the entire feeding device while performing steering operations. At the same time, the two moving pulleys 9 can support the two ends of the moving base 8 to prevent the support frame 2 from tilting to one side on the moving base 8, thereby improving the stability of movement.

The housing of the driving motor 11 is fixedly connected to one end of the support rod 1 through a mounting seat, and the output shaft of the driving motor 11 is fixedly connected to the adjacent driving gear 13. When performing the lifting operation, by starting the driving motor 11, the driving gear 13 is driven to rotate, and the driving gear 13 simultaneously drives the driving toothed belt 12 and the lower lifting screw 4 to rotate, and the driving toothed belt 12 synchronously drives the other driving gear 13 to rotate, thereby completing the synchronous rotation of the two lifting screws 4 and realizing the synchronous movement of the two lifting sliders 3.

[0027] like Figure 1 - Figure 6 As shown, the connection assembly includes a connection sleeve 14 and a T-shaped latch 15. The ends of the two steel coil suspension rods 5 close to the connection plate 7 are penetrated with a connection hole 501. The side wall of the connection sleeve 14 is penetrated with a latch hole 101. The outer wall of the connection plate 7 and the adjacent end of the two steel coil suspension rods 5 are slidably connected with the inner wall of the connection sleeve 14. The insertion rod of the T-shaped latch 15 penetrates the latch hole 101 and the connection hole 501. When the steel coil suspension rod 5 moves to the lifting slider 3 on the other side, the end of the steel coil suspension rod 5 and the connection plate 7 are simultaneously inserted into the connection sleeve 14, and then the T-shaped latch 15 is used to insert the latch hole 101 of the connection sleeve 14 and the connection hole 501 of the steel coil suspension rod 5, so that the two steel coil suspension rods 5 are connected and fixed to the connection sleeve 14, which is convenient to use and simple to disassemble.

[0028] like Figure 1 - Figure 6 As shown, a hand pull ring 16 is fixedly connected to one side of the pull plate 6 away from the two steel coil suspension rods 5. Through the hand pull ring 16, the two steel coil suspension rods 5 can be moved more conveniently through the pull plate 6.

[0030] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that many changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention.
