Referring to fig. 2, the emergency unit further includes an emergency board 18 fixed on the surface of the adjusting plate 16 facing the mounting plate 32 and located on two sides of the adjusting plate, the emergency board 18 extends out of the adjusting groove 12 and is provided with a fine adjustment groove 19, a fine adjustment plate 20 is slidably arranged in the fine adjustment groove 19, a push groove 21 is formed in the fine adjustment plate 20, a push plate 22 is slidably arranged in the push groove 21, a push threaded rod 23 is threaded through the push plate 22, the push threaded rod 23 is rotatably arranged in the push groove 21 and is driven by a fine adjustment motor 24 on the fixed fine adjustment plate 20, a transmission plate 26 is fixed at one end of the transmission rod 25 far away from the mounting plate 32, the transmission plate 26 is fixed with the push plate 22, a transmission groove 27 is further formed in the emergency board 18, and one end of the transmission plate 26 is slidably arranged in the transmission groove 27. The positioning plate 28 is further fixed on the fine adjustment groove 19 of the emergency plate 18, the positioning plate 28 is provided with a yielding groove 29 matched with the shape of the pushing plate 22, the pushing plate 22 and the positioning plate 28 are abutted against the surface of the mounting plate 32 in a natural state, the side of the emergency plate 18 away from the mounting plate 32 is further fixed with a reset cylinder 30, and the end part of a piston rod of the reset cylinder 30 is fixed with a reset plate 31.

When the infrared sensor 57 senses that the limited strip steel is deviated in the conveying process, the emergency unit operates, and the operation is specifically shown in that if the strip steel deviates to the left side, the emergency unit on the right side operates, the fine adjustment motor 24 operates to drive the push threaded rod 23 to rotate so that the push plate 22 pushes the transmission rod 25 so that the mounting plate 32 drives the bearing roller 37 to deviate, thereby driving the included angle between the pressing roller 43 and the bearing roller 37 on the same side to be reduced, so that the strip steel is gradually corrected to the right side, after the position correction of the strip steel is finished, the piston rod of the reset cylinder 30 contracts and drives the reset plate 31 to push the transmission plate 26 until the transmission plate 26 is abutted by the positioning plate 28, at the moment, the fine adjustment plate 20 is also pushed to slide, then the fine adjustment motor 24 rotates reversely, because the transmission plate 26 is abutted by the positioning plate 28 and the reset plate 31 at the moment, the fine adjustment motor 24 rotates reversely to drive the fine adjustment plate 20 to slide along the fine adjustment groove 19 so as to complete the reset of the push plate 22 in the push groove 21, therefore, when the position of the strip steel is corrected, the positions of the bearing roller 37 and the pressing roller 43 can be quickly returned to the positions which are adjusted, so that the correction transition is avoided. When the strip steel deflects to the right, the emergency unit on the left side works.

The working principle and the beneficial effects of the invention are as follows: in the actual production process, the working plate 1 is lifted by the lifting ring 2 and conveyed to a position right above a conveying roller in a working line to be corrected, the position of the working plate 1 is locked by the locking assembly, the lifting cylinder 47 extends to enable strip steel to pass through a position between the pressing roller 43 and the bearing roller 37, the lifting cylinder 47 contracts and rotates the lifting threaded rod 51 to enable the elastically arranged pressing roller 43 to be abutted to the upper surface of the strip steel with a proper thickness of the strip steel and apply certain pressure, then the adjusting handle 15 is rotated to enable the adjusting plate 16 to be ejected outwards by the two adjusting bosses 13, so that the bearing roller 37 is horizontally displaced and simultaneously drives the two pressing rollers 43 and the bearing roller 37 to generate an included angle, and the conveyed strip steel can be conveyed in a limiting manner along with the force generated by the bearing roller 37 actively rotating and the component force generated by the included angle. When the position of the strip is determined and stabilized, the sensing handwheel 56 is adjusted so that the two infrared sensors 57 can be located at both edges of the strip. When the infrared sensor 57 on one side senses the deviation of the strip, the emergency unit on the other side operates and corrects the position of the strip, so that the strip is conveyed while maintaining a stable state.

The above description is only a preferred embodiment of the present invention, and the protection scope of the present invention is not limited thereby, so: all equivalent changes made according to the structure, shape and principle of the invention are covered by the protection scope of the invention.
