The invention discloses an automatic locking device of a hydraulic elevating platform for a furnace. The automatic locking device comprises an elevating platform stop block mounted on the hydraulic elevating platform. A locking hole is formed in the elevating platform stop block. One side of the elevating platform stop block is provided with a locking component used in cooperation with the locking hole. The locking component comprises a safety pin shaft and a driving device connected with the safety pin shaft. One end of the safety pin shaft is provided with a pin head used in cooperation with the locking hole. The other end of the safety pin shaft is connected with the driving device. The driving device can drive the safety pin shaft to move back and forth in the horizontal direction. The hydraulic elevating platform automatic locking device is simple in structure and convenient to use; the technical problem existing when a hydraulic elevating platform for a furnace is kept at a certain height for a long time in the prior art is effectively solved, and the thermal efficiency and production security of furnace equipment are improved.
