Description

Steel belt dismounting trolley for double-belt continuous casting machine Technical Field The invention belongs to the technical field of equipment maintenance of double-belt continuous casting machines, and particularly relates to a steel belt dismounting trolley for a double-belt continuous casting machine. Background In the casting operation of the wide metal liquid plate, the metal liquid is output from the heat preservation furnace, enters the front box of the continuous casting machine through a launder or a pipeline, enters a casting cavity through a pouring nozzle for casting, is cooled and crystallized in the casting cavity to form a plate for output, and is led to the next working procedure. The casting of wide metal plates is generally carried out using twin-belt casters, which are known in the art. The double-belt continuous casting machine comprises a steel belt mechanism which is arranged in pairs up and down, the steel belt mechanism comprises a frame, a tensioning roller and a driven roller which are arranged at intervals along the horizontal direction are arranged on the frame, the steel belt is wound and installed through the tensioning roller and the driven roller to form an annular structure, and the two ends of the steel belt in the width direction are provided with stop blocks. The steel strip is slightly deformed in use due to frequent contact with high-temperature metal liquid, and the coating of the steel strip gradually drops off with the increase of the service time. Therefore, the steel belt needs to be replaced after being used for a period of time so as to ensure that the performance of the steel belt meets the production requirement. When the steel belt to be replaced is taken down, the tensioning roller is required to retract and loosen in the direction close to the driven roller through the oil cylinder, the distance between the tensioning roller and the driven roller is shortened, the steel belt to be replaced is loosened, and then the forklift fork is used for transporting the steel belt supporting plate to replace the steel belt. The supporting plate is stretched into a gap between the tensioning roller and the driven roller, the steel belt to be replaced is supported by the supporting plate, and then the steel belt to be replaced is pulled out in the opposite direction. In the process, the steel belt to be replaced needs to be manually pushed, so that the steel belt to be replaced moves, and the side edges of the steel belt to be replaced are prevented from supporting other positions. Furthermore, the steel belt to be replaced is pulled out through the supporting plate, and the steel belt is mainly pulled out by means of friction force between the bottom of the supporting plate and the steel belt, so that slipping is caused by a little clamping, and the disassembling work is difficult. When the new replacement annular steel belt is installed, the new replacement steel belt is firstly placed on the supporting plate, one end of the new replacement steel belt corresponds to the outer edge of the tensioning roller, and the other end of the new replacement steel belt corresponds to the outer edge of the driven roller. The time consumption of adjusting the position of the new steel belt is long, and after aligning the position, the two baffles on the supporting plate are used for supporting the edge of the new steel belt to push the edge to the direction close to the frame. This way, when slightly hindered, it is easy to bring the baffle against the edge of the newly replaced strip, resulting in deformation of the edge of the newly replaced strip. Moreover, the upper side and the lower side of the newly replaced steel belt are always pushed by manpower, so that the clamping is avoided. Therefore, the replacement time is long, the labor is consumed, and the damage to the newly replaced steel strip is easy to occur.
