Description

1 TARIFF A PARACHUTE BRAKE SYSTEM Technical Area The invention relates to a parachute braking system. The invention specifically enables elevator cabins to operate comfortably at a safe distance from each other. It involves a parachute braking system designed to stop the vehicle. State of the Art Parachute braking systems used in elevators are particularly important in cases of speed violations. safety designed to ensure the elevator stops safely. These systems are components of the elevator. These systems prevent the free fall of the elevator cabin, protecting passengers. It ensures safety. Parachute braking systems typically include a speed regulator and brake levers. It consists of two main components. A speed regulator is a mechanism that continuously monitors the speed of an elevator. If the elevator If a certain speed limit is exceeded, the speed regulator is triggered and the brakes are applied via a cable or wire. It activates the clamps. The brake clamps guide the elevator cabin to the guide rails 15 By holding on tightly, he ensures the elevator slows down quickly and comes to a safe stop. This process helps keep the acceleration that may occur during sudden braking under control, thus protecting passengers. It increases security. False triggering in parachute braking systems is one of the most common problems with these systems. It is one of them. An extremely precisely adjusted speed regulator will trigger a 20 when the speed limit is exceeded slightly. This could accidentally activate the system, causing the elevator to stop unnecessarily. It is possible. Also, power outages or mechanical vibrations can cause false alarms. This, This can cause unnecessary panic among elevator passengers. Mechanical failures are another common problem in parachute braking systems. Brake failures... the clamps failing to grip the guide rails or not releasing as required 25 Failure to release the brakes can negatively affect the braking process. Such mechanical problems... This could jeopardize the elevator's safe stopping position. High cost and complexity are another disadvantage of parachute braking systems. This The installation and regular maintenance of these systems can be costly. Furthermore, the complexity of the systems... 2 This can complicate maintenance and repair procedures and may require more expertise. Performance limitations are also an important issue. Sudden stops can have an impact on passengers. It can create discomfort and stress, and excessive braking force can damage the cab and steering rails. This can create excessive loads on them. If the shock absorber systems do not function effectively, The effects of the sudden stop can cause serious discomfort and injuries to passengers. 5 As a result of the investigation conducted regarding this matter, application number US4538706A It has been encountered. The aforementioned application is a safety tool and a guide for elevators. on one side of the rail is a brake shoe and on the other side are two leaf springs and a roller. has. In conclusion, due to the negative aspects described above and the current solutions regarding topic 10 Due to its shortcomings, an improvement is needed in the relevant technical field. It has been made. The purpose of the invention The invention was created by drawing inspiration from existing situations and overcoming the aforementioned drawbacks. It aims to solve it. 15 One aim of the invention is to replace the spring in the parachute brake with a spring, unlike existing sliding parachute brakes. The goal is to install a system that allows for adjustment of the braking force using a mechanism. Another purpose of the invention is to reduce the discomfort caused by the braking system to passengers. The goal is to reduce its impact. Another purpose of the invention is to enclose the passenger cabin inside an outer cabin, thereby improving braking. The aim is to minimize the discomfort during the process. To achieve the purposes described above, elevator cabins must be opened suddenly. to ensure that, in the event of acceleration, it can be stopped comfortably within a safe distance. on which the elevator cabins are guided and on which they move linearly. Used by being positioned between the rails and the elevator cabins, the elevator goes up or down 25 When it accelerates suddenly downwards, it moves parallel to the movement of the elevator car.
