Description

Technical Field

[0001] The present invention relates to the technical field of special equipment, and in particular to a pulley releasing device with interlocking protection and a releasing method. Background Art

[0002] Unpowered amusement ziplines are already a common entertainment item in amusement parks. However, with the popularity of ziplines, the number of safety accidents has also increased accordingly. A large part of these accidents is caused by improper operation of the staff. When the arrival station is not ready, the departure station staff releases the zipline too early, thus causing safety accidents.

[0003] To address this issue, new technical requirements for the interlocking protection of the zipline release device have been added to the "GB / T 3125802024 General Technology for Zipline" which will be implemented soon. The requirements state that the operator at the arrival station needs to confirm that the passengers have left safely and then operate the release button. The operator at the departure station can only activate the release interlocking device to release the vehicle after receiving the release signal.

[0004] At present, there are two widely used methods for releasing the pulley in China. One is to use a simple small plate hook fixed on the wire rope at the departure station and reset by gravity or spring; the other is to use a safety lock to prevent the pulley from sliding down. Both methods are manually operated by the staff at the departure station. The disadvantage is that if the passengers at the departure station do not wear seat belts or the arrival station is not ready, once the staff neglects to release the pulley, an accident is likely to occur, which poses a great safety hazard. Therefore, it is urgent to make a pulley release device that can standardize the operating process, allow the staff at the arrival station to participate in the control, and has interlocking protection, which can improve the safety of tourists when riding the pulley. Summary of the invention
