Abstract

A drop impact reducing device of a pneumatic elevator is provided to maximize safety of a passenger and to minimize loss of life and property by installing a safety device for reducing the drop impact of the pneumatic elevator. A drop impact reducing device of a pneumatic elevator(2) includes a cylinder(3) and a groove(4). The cylinder is installed under the pneumatic elevator. The groove is formed at a bottom of the pneumatic elevator. The groove is formed at a predetermined position corresponding to the cylinder. The cylinder is pressed firstly in a dropping state of the pneumatic elevator. The impact of the pneumatic elevator is reduced by using the internal pressure of the groove.

Description

Reduce device by air absorber force of elevator drop impact

      Technology to stop the elevator in case of emergency by utilizing the principle that the compression force inside the trough is generated when the cylinder is engaged with the trough

Principle of Air Up Shobar_The air is compressed inside the gutter when the cylinder is pressed on both sides, and the pressure inside the gutter rises faster as you press it faster. Technology to stop the elevator safely by absorbing the shock by the pressure of the cylinder and the trough suggested by the contents below

      Once installed, elevators have been used for decades, such as building life, but the number of accidents caused by the fall of elevators is increasing year by year. There are safety devices equipped with brakes and various electronic devices, but when used for a long time, these safety devices are unexpectedly failing to function properly in the event of an emergency, resulting in human and physical damage. Many personal and physical damages are also caused by installing safety devices that alleviate the fall impact of elevators, which do not inherently change their original functions even after long-term use. Ultimately, the safety of the occupants is maximized to minimize human physical damage. Challenges to be addressed by this proposal The.

The present invention relates to the development of a shock-absorbing device that does not have a risk of operating defects even after a long time, and also requires no maintenance, and is equipped with a cylinder of a certain size at the bottom of the elevator when the elevator falls and a gutter is installed at the bottom floor It can be understood as a type of large air upshoe bar which safely stops the elevator by the pressure of the air inside the cylinder and the trough structurally contacted during the fall.

It is a semi-permanent safety device that requires no maintenance at all, and does not worry about the change of intrinsic function even after a long time, and has the same life as a building. .

(2) The cylinder-shaped structure is installed at the bottom of the elevator. (4) The structure having the structure of the gutter is installed at the bottom of the first floor. (4) The pressure inside the gutter is rapidly increased so that the elevator stops rapidly. (5) The device consists of (6) exhaust pipe, which is a passage through which the air is discharged to the outside through the pressure exhaust valve and the exhaust valve so as to control the pressure so as to prevent pressure. (2) The elevator falls to the bottom layer at a high speed, and when it reaches the floor, (2) the cylinder is installed at the bottom of the elevator (3) and the cylinder (4) the gutter on the fart side meets (4) the inside of the gutter (2) the elevator stops slowly as it rests on the sponge, and (4) the compression pressure of the trough depends on the (2) dropping speed of the elevator. It is a very simple structure consisting of (4) pressure control valve for the purpose of adjusting the proper pressure inside the gutter, and (4) exhaust pipe for discharging a certain amount of air to the outside. This form can be easily understood by the general public, and more detailed description is replaced with the accompanying drawings.

Such air-compression shock-absorbing device is used in a variety of forms in the industrial field, and the present invention has a very simple principle and structure, and is an invention that can be applied immediately.

Figure 1 shows the overall structure as a concept image according to the present invention.

2 shows a shape in which air compression occurs.

Figure 3 shows the compression of air and the falling speed of the elevator on the time axis.

Claims (2)

Safety device installed for the purpose of preparing for the impact of falling of the elevator which is installed under the elevator and installed in the form of an air upshoe bar having the structure of a trough on the floor of the floor. A gutter is installed on the first floor and a cylinder is installed at a certain height so that when the elevator falls, the cylinder is pressed first (the gutter and the cylinder can be installed oppositely) and meet the gutter to relieve the impact by using the pressure inside the gutter. , Safety device ,.
