Abstract

Provided is a novel rack assembling mechanism. A rack is installed on a bracket, and is locked by a check block and a locking hydraulic cylinder, so as to prevent the rack from being tipped over. An overturn arm is connected with the bracket through a pivoting support, a front bolt and a back bolt. The tail end of the overturn arm is connected with a piston rod end of an overturn hydraulic cylinder. The overturn hydraulic cylinder is installed on a pedestal. The rack is installed on the bracket, and a hydraulic motor drives the rack to rotate. When the rack is in a certain position, a locating hydraulic cylinder rod end is inserted inside a hole on the bracket, and the bracket is fixed in a horizontal position; the overturn hydraulic cylinder drives the rack to overturn in 90 degrees through a revolving arm. The pivoting support is subjected to an axial load, a radial load and an overturn torque of the mechanism. Actions of the entire mechanism are all achieved by hydraulic systems. The novel rack assembling mechanism is compact, reliable and simple in structure, accordingly increasing the assembling and maintaining efficiencies of the rack greatly.

Description

technical field [0001] The invention belongs to the technical field of metallurgical equipment, in particular to a novel frame assembly mechanism. Background technique [0002] During the use of the rolling mill, the frame needs to be disassembled frequently to meet the requirements of changing roll rings and maintenance. The existing frame assembly mechanism is fixed and cannot be flipped and rotated by itself. It needs to cooperate with the crane to carry out assembly and maintenance work on the frame, which is low in work efficiency and difficult to operate. Therefore, a rack assembly mechanism is needed to meet the requirements of rapid assembly, which can rotate, flip and position itself to match the work requirements of workers at various angles. At the same time, the assembly mechanism is all driven by hydraulic pressure, and the action of the mechanism can be operated on the console, which is easy for workers to operate, provides all-round convenience for workers' m...
