Description

Technical Field

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

[0002] Steel coil, also known as coiled steel, is formed into coils by hot or cold pressing. In order to facilitate storage and transportation, and to facilitate various processing (such as processing into steel plates, steel strips, etc.), an uncoiler is generally used when processing steel coils.

[0003] At present, when the steel coil uncoiler on the market is in use, one side of the hollow shaft is suspended in the air, and the root of the hollow shaft will be subjected to a large bending moment. In addition, as the steel coil rotates, the root of the hollow shaft will also be subjected to alternating stress, which is prone to cracks and shortens the service life. The prior art supports the hollow shaft by providing a supporting structure at the bottom of the hollow shaft, thereby increasing the service life. However, the supporting structure occupies a large area when in use. Although the occupied area can be reduced by bending, the supporting structure will still occupy the space under the hollow shaft, affecting the loading or unloading of the steel coil, which has certain limitations.

[0024] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0025] It should be noted that all directional indications in the embodiments of the present application are only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture. If the specific posture changes, the directional indication will also change accordingly.

[0026] In this application, unless otherwise clearly specified and limited, the terms "connection", "fixation", etc. should be understood in a broad sense. For example, "fixation" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0027] When in use, after the steel coil is transported by the mobile lifting structure, the steel coil is placed on the outside of the hollow shaft, and then the driving motor in the uncoiler body is turned on to rotate the hollow shaft to uncoil the steel coil.

[0028] In the related art, during the uncoiling process, the hollow shaft is supported to prevent one side of the hollow shaft from hanging in the air, thereby increasing the service life. The supporting structure can be laid flat by rotating when not in use to reduce the occupied area. However, when in use, the supporting structure cannot be stored, which still affects the normal uncoiling of the steel coil.

[0029] In order to solve the problems in the related art to a certain extent, the embodiment of the present application provides a steel coil unwinding device. When unwinding is required, the steel coil only needs to be installed on the hollow shaft 13, and after the plate 26 is in contact with the hollow shaft 13, the unwinding machine body 12 is opened for unwinding, and the hollow shaft 13 is supported by the frame 22 and the plate 26. After use, the frame 22 and the plate 26 are stored in the trough 1 24 and the trough 25, which will not affect the normal use of the unwinding machine body 12.

[0030] The present application is described below with reference to the accompanying drawings and specific embodiments:

[0031] Combination Figure 1-Figure 2The embodiment of the present application provides a steel coil uncoiler, comprising a main body component 1; the main body component 1 comprises: a base 11 on which an uncoiler body 12 is arranged; a hollow shaft 13 is arranged on the uncoiler body 12; a support component 2 is arranged on the base 11; the support component 2 comprises: a slide rail 21 is arranged on the base 11; a frame 22 is slidably connected to the slide rail 21; a groove body 1 24 is opened on one side of the uncoiler body 12; a groove body 25 is opened on one side of the uncoiler body 12; a fixing bolt 1 23 is arranged on the frame 22; a plate body 26 is slidably connected to the frame 22, and one end of the plate body 26 is tightly attached to the outer side of the hollow shaft 13; a fixing bolt 27 is threadedly connected to the frame 22.

[0032] When in use, after the steel coil is transported by the mobile lifting structure, the steel coil is placed on the outside of the hollow shaft, and then the frame 22 is pulled to make the frame 22 drive the plate 26 to slide on the slide rail 21 until the plate 26 slides to the bottom of the hollow shaft 13, and then the fixing bolt 23 is turned to fix the position of the frame 22, and then the plate 26 is pulled upward to make one end of it contact with the hollow shaft 13, and then the fixing bolt 27 is turned to fix the height of the plate 26, so that the plate 26 has a better supporting effect on the hollow shaft 13, and then the opening is opened. The driving motor in the coiler body 12 rotates the hollow shaft 13 to unwind the steel coil. During the unwinding process, the plate body 26 always supports the hollow shaft 13 to increase the service life of the hollow shaft 13. After use, the second tightening bolt 27 is rotated in the opposite direction to make the plate body 26 lower than the hollow shaft 13, and then the tightening bolt 1 23 is rotated to push the frame body 22 to make the frame body 22 and the plate body 26 slide into the groove body 1 24 and the groove body 25, thereby completing the storage of the frame body 22 and the plate body 26 without affecting the normal use of the unwinder body 12.

[0033] In some embodiments, the cross section of the slide rail 21 is circular, so that the frame 22 can slide more stably.

[0034] In some embodiments, a plurality of slide rails 21 are provided, and are threadedly connected to the uncoiler body 12 , so that the slide rails 21 can be easily disassembled without affecting the normal use of the frame 22 .

[0035] In some embodiments, the support assembly 2 also includes: a hole 28 is opened on the plate body 26, and one end of the fastening bolt 27 is inserted into the hole 28. When fixing the plate body 26, the fastening bolt 27 is rotated so that the fastening bolt 27 slides on the frame body 22 and is inserted into the hole 28, which has a better fixing effect on the plate body 26.

[0036] In some embodiments, the support assembly 2 further includes: a limit block 261 fixedly connected to the plate body 26 to prevent the limit block 261 from being separated from the plate body 26 .

[0037] In some embodiments, the support assembly 2 further includes: a curved surface 29 disposed on the plate body 26 to increase the contact area between the plate body 26 and the hollow shaft 13 .

[0038] In some embodiments, a rotating assembly 3 is disposed on the plate body 26 ; the rotating assembly 3 includes: a slot body 31 opened on the plate body 26 ; and a rod body 32 rotatably connected in the slot body 31 .

[0039] When in use, when the hollow shaft 13 rotates, it drives the rod body 32 to rotate in the groove body 31, reducing the friction force generated by the hollow shaft 13 when rotating, thereby increasing the service life.

[0040] In some embodiments, the rotating assembly 3 is provided with multiple groups and is an arc-shaped device with the same arc as the arc surface 29, so that multiple rods 32 are in contact with the hollow shaft 13 at the same time.
