The utility model relates to a pneumatic brake release apparatus used on an elevator traction machine, which includes an air cabin, an air storage tank, air delivery pipes, air films, a push rod and air control apparatuses, wherein the air films are arranged at two sides in the air cabin, one end of the push rod is connected to the air films, the other end of the push rod penetrates through the outer wall of the air cabin and is connected with the upper end of a locking arm, an intermediate air cabin of the air cabin is provided with an intermediate air inlet end and an intermediate air outlet end, a film-anterior air cabin of the air cabin is provided with a film-anterior air inlet end, the intermediate air inlet end and the film-anterior air inlet end of the air cabin are respectively connected with the air storage tank by virtue of the air delivery pipes, and the intermediate air outlet end is directly communicated with the atmosphere. By means of the technical solution, the air films in the air cabin are pushed by using compressed air to drive the push rod to transfer a thrust force, so that the locking arms are unfolded, and the locking brake and the brake release are implemented in a pneumatic way. Therefore, the problems in the prior art that a great amount of electric energy is consumed and the noise is difficult to eliminate can be solved, no noise is generated during operation, the safety is high, the structure is simple, and the manufacturing cost is greatly reduced.
