Description

Loop lifting positioning device Technical Field The utility model belongs to the technical field of metal strip machining, and particularly relates to a loop lifting positioning device. Background In industrial production plants, such as air-cushion furnaces, a loop is a device for storing and conditioning material, such as metal strip, generally consisting of several rollers, driving devices, control systems, etc. In the processing process of the strip, the loop of the air cushion furnace can adapt to different production speeds and control the tension of the strip through lifting, thereby meeting the technological requirements of different products. The loop needs four corners to synchronously and stably lift in lifting so as to avoid the deviation of the strip on the roller of the loop caused by unstable lifting, thereby influencing the quality of the product. If the loop is not lifted stably, the deviation of the strip is caused, and then in order to ensure the product quality, production operators need to readjust the relative position of the strip at the center of the machine row through the S roller pair after the loop, and the S roller cannot adjust the deviation of the strip in severe cases, so that the product quality and the production efficiency of the strip winding uniformity are seriously affected. Disclosure of utility model The utility model aims to provide a loop lifting positioning device, wherein each corner of a loop frame can lift in two vertical track surfaces which are perpendicular to each other, so that stable lifting of a loop is ensured, and the deviation of a strip is avoided. In order to achieve the purpose, the technical scheme includes that the loop lifting positioning device comprises a lifting frame and a loop frame, lifting track groups are arranged at four corners of the lifting frame, each lifting track group comprises two vertical track surfaces which are perpendicular to each other and are a transverse track surface and a longitudinal track surface, lifting roller groups are arranged at four corners of the loop frame, each lifting roller group comprises a transverse roller and a longitudinal roller, the transverse rollers run along the transverse track surfaces, and the longitudinal rollers run along the longitudinal track surfaces. Further, at any angular position of the loop frame, the lateral roller is disposed below the loop frame and the longitudinal roller is disposed above the loop frame. Further, at any angular position of the loop frame, the lateral roller is disposed above the loop frame and the longitudinal roller is disposed below the loop frame. Further, in the width direction of the loop frame, two transverse rollers oppositely disposed run on two opposite transverse track surfaces to form a grip of the two transverse track surfaces by the two transverse rollers. Further, in the length direction of the loop frame, two opposite longitudinal rollers run on two opposite longitudinal rail surfaces, so that the two longitudinal rail surfaces hold the loop frame. Further, the transverse roller and the longitudinal roller are both bearings. Further, the bearing is a cylindrical roller bearing. Further, the transverse roller or the longitudinal roller is arranged on a pin shaft, the pin shaft is fixed in an inner hole of a roller mounting seat, and the roller mounting seat is fixed on the upper surface or the lower surface of the loop frame. Further, the roller mounting seat is fixed on a connecting plate, and the connecting plate is fixed on the loop frame through a connecting bolt. Further, a connecting rib plate is arranged outside the connecting plate, and a connecting bolt penetrates through the connecting rib plate and the connecting plate to be connected with the loop frame. The loop frame has the beneficial effects that two sets of rollers are arranged at each corner of the loop frame, so that each corner of the loop frame can run in two mutually perpendicular track surfaces, the lifting stability of the loop can be improved, the synchronism of four corners of the loop can be ensured, the bearing capacity of the loop can be improved, and the loop can adapt to complex working conditions. The specific analysis is as follows: 1. The stability improvement is mainly embodied in (1) preventing the loop from tilting or swaying, and the two sets of rollers at each corner of the loop frame run in two perpendicular track planes respectively, which can support and restrain the loop from multiple directions. When the loop is acted by external force (such as uneven distribution of strip tension, vibration in running of equipment, etc.), the rollers in different track surfaces can be mutually matched to offset the moment generated by partial external force, so that the loop is effectively prevented from tilting or shaking, and is kept in a stable posture in the lifting process, and (2) the structural rigidity is enhanced, and the two rollers at each angle of the loop fr
