Description

Technical Field

[0001] The utility model relates to a braking device, in particular to a passive braking device for a monorail pulley. Background Art

[0002] The monorail pulley is a mass entertainment facility with a strong sense of experience. The track is built on the hillside, and the potential energy of the slope is used to provide driving power for the pulley. The pulley starts from the top of the hillside, and the speed will gradually increase before reaching the bottom of the slope. It is necessary to set a dynamic brake device to control the speed of the pulley well. At present, the braking device of the monorail pulley is mainly a handbrake and a high-speed limiting brake device installed on the pulley. Although the existing braking device is convenient to use, when the pulley stops at the stop point, it needs to be actively operated by the passengers on the car, which may cause some problems for the operator. For example, improper operation by the passengers or some unexpected situations will prevent the pulley from stopping at the stop point, which will cause inconvenience to the operator. Summary of the invention

[0003] The technical problem to be solved by the utility model is: to provide a passive braking device for a monorail pulley to assist the pulley to stop at a predetermined position.

[0004] The technical solution of the utility model is: a passive braking device for a monorail pulley, including a pulley track and a braking device, the braking device including a friction damping plate, a fixed support and a connecting frame that cooperate with the slide of the pulley, the friction damping plate and the fixed support are arranged on both sides below the pulley track, the friction damping plate and the fixed support are connected by a hinged connecting rod and a pressure spring, the hinged connecting rod is arranged obliquely rearward and is respectively hinged to the friction damping plate and the fixed support, the two ends of the pressure spring act on the friction damping plate and the fixed support respectively, and the fixed support is fixedly connected to the pulley track through the connecting frame.

[0005] The technical effect of the utility model is that it has the advantages of simple structure, reasonable design, reliability and durability, and cooperates with the slide of the pulley to achieve the purpose of passive braking of the pulley. The spring is used to provide braking force, which has good buffering performance and makes the braking process smoother. When the pulley is in an unloaded state, the pressure on the friction plate support spring is also reduced accordingly, making it easy to move the unloaded car. The pressure of the manual brake friction plate can be reduced and its service life can be extended. BRIEF DESCRIPTION OF THE DRAWINGS
