[0001] The present application relates to the technical field of oxygen lances, and in particular to a tool for measuring the braking distance of an oxygen lance lifting trolley. Background Art

[0002] The oxygen lance system is an important equipment for converter steelmaking. The key equipment in the system, the oxygen lance lifting trolley, performs lifting and reciprocating motion in a fixed track by pulling a steel wire rope to perform blowing work. During the lifting process of the oxygen lance lifting trolley, its safety performance must be absolutely reliable and no falling accidents are allowed. Therefore, the external mechanism of the oxygen lance lifting trolley is designed with a passive anti-fall device, and it is also equipped with an active mechanical anti-fall mechanism. It must be fast, sensitive, reliable and easy to maintain to ensure the use function of the oxygen lance lifting trolley.

[0003] The brake device of the oxygen lance lifting trolley is manually positioned and fixed on the oxygen lance lifting base before the system is installed. The positioning gap between the brake device and the lifting rail is 6-8mm, which can ensure that the brake device can quickly brake the oxygen lance lifting trolley when the reciprocating action of the oxygen lance lifting trolley is out of control, preventing the oxygen lance from falling and causing greater production accidents. Due to the replacement cycle of the oxygen lance lifting trolley and the long-term wear of the lifting rail tread, the gap between the brake device and the lifting rail will increase, causing serious production accidents such as the lance falling.

[0004] Therefore, we propose a tool for measuring the braking distance of an oxygen gun lifting trolley to better solve the above technical problems. Summary of the invention
