Description

Roll changing equipment system of combined type rack straightener Technical Field The invention relates to a combined type frame straightening machine type, an automatic roll changing vehicle and a roll changing integrated frame in an integral structure form matched with a maintenance base for use under the process condition of roll changing of a transverse track. Background A section steel straightening production line adopting a combined type frame straightening machine type (Combined rack type) adopts an automatic roll changing machine integral grouping roll changing process for matching the productivity of a rolling line, reducing the roll changing operation time and improving the roll changing efficiency. The combined straightening machine frame is mainly formed by combining an operation side frame, a transmission side frame, a front frame and a rear frame for carrying the vertical rolls, wherein the frame is in a closed state, besides the operation side frame can move along a longitudinal moving track which is the same as the axial line direction of the straightening rolls, the rest parts of the combined frame are relatively fixed in a corresponding connection mode, and the frame is required to be opened during roll changing to detach or mount the straightening rolls. When the straightening operation is carried out, the straightening roller is carried by the operating side frame to move on a longitudinal track along the axial direction of the straightening roller under the driving of a hydraulic cylinder after the fastening condition of the straightening roller system and the operating side frame is unlocked, and a condition that the straightening roller can be moved out in the radial direction is formed after the straightening roller reaches the roller changing position. Under the process condition of automatic roll changing vehicles in groups, typical process arrangement and equipment configuration modes of a straightening operation area are that a transverse moving track is arranged in parallel along a straightening center line at a certain distance from a straightening machine and used for running of the automatic roll changing vehicles, and the transverse moving track is provided with an automatic roll changing vehicle on each of inlet and outlet direction tracks of the straightening machine. Before straightening operation, the automatic roll changing vehicles stay on the waiting positions respectively, and one of the automatic roll changing vehicles loads a new straightening roll. When the combined type machine frame is used for roll changing operation, the operation side machine frame is opened, the old straightening rolls are carried by the operation side machine frame to the roll changing position, the empty automatic roll changing machine frame is stopped at the roll changing position of the transverse moving track after being driven into the roll changing area of the machine frame, the old straightening rolls are moved onto the automatic roll changing machine frame from the operation side machine frame through the straightening roll carrying method, the automatic roll changing machine frame carrying the old straightening rolls is moved out of the roll changing area of the combined type straightening machine, the automatic roll changing machine frame carrying the new straightening rolls is stopped at the roll changing position of the transverse moving track after being driven into the roll changing area of the machine frame, and the unloaded automatic roll changing machine frame is driven out of the roll changing area of the combined type machine frame after the new straightening rolls are driven onto the operation side machine frame through the straightening roll carrying method. The operating side frame is moved to a roll changing position, an empty automatic roll changing vehicle 1 arranged at the left side of the straightener enters a roll changing position of a traversing rail in the frame, and an automatic roll changing vehicle 2 for loading new straightening rolls is positioned at a waiting position on the traversing rail. The combined frame straightener transverse track automatic roll changing machine group integral roll changing process is an automatic process for automatically disassembling and assembling straightening rolls under a three-dimensional coordinate system. In the automatic roll changing process, the old straightening roll carried on the operating side frame is transferred to the automatic roll changing vehicle, the new straightening roll carried on the automatic roll changing vehicle is transferred to the operating side frame, the functional structure of the carrying straightening roll is a cantilever type roll shaft no matter whether the operating side frame or the automatic roll changing vehicle is adopted, the cantilever type roll shaft in a short half shaft mode is inserted into a central hole of the straightening roll in an exchanging mode, one pull claw locks the
