Description

Technical Field

[0001] The utility model belongs to the technical field of high-temperature material transfer, and in particular relates to a transfer forklift for high-temperature casings. Background Art

[0002] After high temperature forging, the casing blank usually needs heat treatment to maintain the mechanical durability of the workpiece. However, the workpiece after high temperature forging usually has high temperature residual heat. If it can be transported to the heat treatment equipment for heat treatment in time, the heating energy consumption of the heat treatment can be greatly reduced. However, the workpiece with high temperature residual heat is usually not easy to transfer and transport.

[0003] In the prior art, the patent document with the announcement number CN 108438766 A discloses a forklift and a machine automatic transfer feeding device, including a transmission mechanism and a lifting transfer mechanism, wherein the transmission mechanism includes a reduction motor and a transmission chain connected to the output shaft of the reduction motor, and the transmission chain is connected to the lifting transfer mechanism; the lifting transfer mechanism includes a connecting plate, a telescopic rod, a supporting plate and a transition plate, wherein one end of the connecting plate is slidably connected to the side of the transition plate, and the other end is fixedly connected to the bottom end of the telescopic rod; one end of the supporting plate is slidably connected to the side of the transition plate, and the other end is fixedly connected to the upper part of the telescopic rod. The above scheme realizes the fully automatic transfer docking between the forklift and the strip material transfer mechanism through the perception of the sensor, thereby improving the transfer efficiency, but it is not suitable for the special transmission of cylindrical workpieces such as high-temperature sleeves, and its electronic components such as sensors are prone to failure or damage when used in a high-temperature environment, and its manufacturing cost is relatively high.
