Anti-falling safety device of lifting trolley of converter oxygen lance

Abstract

The invention discloses an anti-falling safety device of a lifting trolley of a converter oxygen lance. The anti-falling safety device comprises a lifting trolley provided with the converter oxygen lance, a sliding rail is arranged behind the lifting trolley, a moving device which moves along with the lifting trolley is arranged on one side of the sliding rail, the moving device is fixedly connected with the lifting trolley through a locking device, the moving device moves along with the lifting trolley when the lifting trolley moves in rated speed, when the downward running speed of the lifting trolley exceeds the rated speed, the locking device automatically locks the movement of the moving device so as to realize braking. According to the anti-falling safety device, the concept is ingenious, the structure is reasonable, the overall structure is simple, installation and maintenance are convenient, operation stability is high, when a steel wire rope is broken, the lifting trolley canbe stably locked on the sliding rail, be prevented from continuously falling, and normal production can be simply and rapidly recovered after the braking.

Description

technical field [0001] The invention relates to a fall prevention device, in particular to a fall prevention safety device for a converter oxygen lance lift trolley that is simple in structure, easy to use, and capable of preventing the lifting trolley from falling along the lifting track after the wire rope breaks, and braking smoothly. The invention belongs to the technical field of converter steelmaking equipment. Background technique [0002] At present, most of the oxygen lance systems used in supporting converter smelting in the steelmaking workshop are imported equipment. The oxygen lance system is controlled by the lifting device to raise or lower the oxygen lance and sub-lance, and its performance characteristics directly affect the smelting effect and blowing. Time, which affects the quality and output of steel. [0003] The domestic independent innovation of the oxygen lance system has just started in recent years. When the wire rope lifting the lance breaks acc...

Problems solved by technology

[0004] Existing anti-fall devices include clamping plate type and inclined wedge type, but the braking is unreliable, sometimes successful and sometimes unsuccessful, if the braking is successful, it may be difficult to remove because the clamping rail is too tight, and it is prone to rail clamping during normal work Phenomena and other shortcomings
