Abstract
The invention discloses a novel pulley, which is mainly used in the field of amusement equipment, in particular to a pulley for a slide cable. The tackle is a four-wheel tackle which is symmetrical left and right. The pulley is connected with the pulley shaft bracket through a fastener, and the brake block is connected with the pulley shaft bracket through a pin shaft. One end of the torsional spring is connected with the pulley shaft bracket, the other end of the torsional spring is connected with the brake block, and one end of the link rod is connected with the brake block through a pin shaft. Two ends of the pulley shaft support are connected with the circulating cable, and the other end of the yoke plate is connected with the circulating cable through a steel wire rope. When the pulley normally slides along the steel wire rope, the circulating cable is in a tensioning state, the tension of the circulating cable overcomes the torsion of the torsion spring to pull the link rod and drive the brake block to rotate, and the brake block is separated from the pulley wheel, so that the pulley is ensured to normally slide. When the circulating cable is broken, the tension of the circulating cable disappears, and the brake block rubs with the pulley wheel under the action of the torsion spring, so that the pulley is decelerated and finally stops. The problem of when circulating the cable fracture the coaster high speed glide, dash the station and lead to the passenger casualty is solved.
Description
Technical Field
The invention relates to the field of amusement equipment, in particular to a pulley with a speed reduction buffer sliding rope.
Background
The strop cord is also called: "rope slipping", "fast descent", "flying in the air", etc. Originating in the mountain country switzerland. The method is originally used for self-rescue in mountains and military sudden attack actions, and is evolved into an amusement project. When the sliding trolley slides downwards, the small sliding trolley at the other side and the lower station is pulled to the upper station through the circulating system, and the sliding trolley continues to slide for the next time. Under normal working conditions, the tackle slides, stimulates and is mounted on the tackle at normal speed by means of the resistance generated by the circulation system and the braking system. If the circulating cable is broken, the circulating system and the brake can fail, and serious consequences can be caused.
At present, the pulley running on the deceleration buffering sliding cable in China basically has no circulating cable breakage protection device, once the circulating cable is broken, the pulley carries passengers to rush into a station at a high speed, and serious personal injury is caused to the passengers.
Disclosure of Invention
The invention discloses a pulley capable of effectively decelerating and braking the pulley after a circulating cable is broken. The pulley aims to solve the problems that when the existing pulley is broken by a circulating cable, the pulley slides downwards at a high speed, so that passengers rush into a lower station at a high speed and are injured and killed.
The technical scheme of the invention is as follows:
the utility model provides a novel coaster of disconnected cable protection device in area which characterized in that, includes the coaster: the pulley is a four-wheel pulley and is symmetrical left and right. The pulley is connected with the pulley shaft bracket through a fastener, and the brake block is connected with the pulley shaft bracket through a pin shaft. One end of the torsional spring is connected with the pulley shaft bracket, the other end of the torsional spring is connected with the brake block, and one end of the link rod is connected with the brake block through a pin shaft. Two ends of the pulley shaft support are connected with the circulating cable, and the other end of the yoke plate is connected with the circulating cable through a steel wire rope.
The invention aims to realize that when the tackle normally slides along the steel wire rope, the circulating cable is in a tensioning state, the tension of the circulating cable overcomes the torsion of the torsion spring to pull the link rod and drive the brake block to rotate, and the brake block is separated from the pulley wheel to ensure that the tackle normally slides. When the circulating cable is broken, the tension of the circulating cable disappears, and the brake block rubs with the pulley wheel under the action of the torsion spring, so that the pulley is decelerated and finally stops.
Drawings
Fig. 1 is a main view of the novel scooter.
Fig. 2 is a schematic diagram of the operation of the novel tackle after the endless cable is broken.
Detailed Description
For a more complete and complete description of the structure and principles of the present invention, reference is now made to the following descriptions taken in conjunction with the accompanying drawings.
As shown in the figure: two ends of the sliding cable circulating cable are respectively connected to the pulley shaft bracket 8. When the tackle normally slides along the steel wire rope, the circulating cable 2 is in a tensioning state, the tension of the circulating cable 2 overcomes the torsion of the torsion spring 7 to pull the link rod 4 and drive the brake block 6 to rotate, and the brake block 6 is separated from the pulley wheel 3, so that the tackle is ensured to normally slide. When the circulating cable 2 is broken, the tension of the circulating cable disappears, and the brake block 6 rubs with the pulley wheel 3 under the action of the torsion spring 7, so that the pulley is decelerated and finally stops.
