Problems solved by technology
In the traditional movable arch rolling mill, the tension hydraulic cylinder in the locking device of the tie rod beam is in a high-pressure working state for a long time, so that the seals of the hydraulic cylinder are prone to oil leakage and pressure relief.
Frequent replacement of tie rod tightening hydraulic cylinders, long disassembly and assembly time, and replacement of tie rod tightening hydraulic cylinders lead to production stoppage of the rolling line, high cost and wasteful situation

The invention provides a rolling mill pull rod locking device with a movable machine frame. The rolling mill pull rod locking device comprises a pull rod, an insertion plate locking device, an operation side machine frame body, a cross beam, a transmission side machine frame body, a pull rod limiting device and a pull rod tensioning hydraulic cylinder. An operation side gateway and a transmission side gateway are arranged in parallel. The pull rod penetrates through the operation side machine frame body and the transmission side machine frame body and is connected with the pull rod tensioning hydraulic cylinder through a thread. The insertion plate locking device is fixedly arranged on the outer side of a vertical roller cross beam on the operation side. The pull rod is provided with a limiting groove matched with an insertion plate. The pull rod limiting device is arranged between the transmission side machine frame body and the pull rod tensioning hydraulic cylinder. A first oblique insertion plate is in frictional contact with a second oblique insertion plate when pushed out. According to the rolling mill pull rod locking device, the pull rod is locked through the insertion plate, and movement of the pull rod is limited. The oblique surface of the pull rod tensioning hydraulic cylinder and the oblique surface of the pull rod limiting device are in contact so as to achieve automatic locking, the pull rod tensioning hydraulic cylinder stops working, a clearance between the insertion plate of the insertion plate locking device and the pull rod limiting groove is eliminated, and the operation side machine frame body and the transmission side machine frame body are locked into a whole.
Description
technical field [0001] The invention belongs to the field of movable archway rolling mill equipment, and in particular relates to a rolling mill pull rod locking device with a movable stand. Background technique [0002] In recent years, with the rapid development of my country's economy, people's consumption level has been continuously improved, which has greatly promoted the vigorous development of civil construction, automobile and other industries. The government has also spared no effort to increase investment in infrastructure. As an upstream beneficiary industry, the iron and steel industry has been greatly developed, but at the same time it has put forward higher requirements on the production efficiency of the industry, and in order to reduce energy consumption and save costs, it has been put at the top of the list. In the traditional movable archway rolling mill, the tie rod tightening hydraulic cylinder in the locking device of the tie rod crossbeam is in a high-...
