Description

Technical Field

[0001] The utility model mainly relates to the technical field of elevators, and in particular to an elevator buffer. Background Art

[0002] The elevator buffer is a safety device of the elevator. The device is installed at the bottom of the elevator shaft. When the elevator loses control, the elevator buffer can alleviate its impact force and play a role in protecting the safety of passengers and equipment. Most of the existing elevator buffers only use one hydraulic buffer, which is set at the center of the bottom of the elevator shaft. Due to the small contact area with the car, it is not only easy to cause damage to the car, but also when the passengers in the elevator are unevenly distributed, it will cause uneven force on the car, which may cause safety hazards.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances. Example

[0024] Refer to the attached Figure 1-4 An elevator buffer comprises a first hydraulic buffer 1 and a first buffer plate 2. There are four first hydraulic buffers 1, and a first connecting plate 3 is arranged on the top, and a second connecting plate 4 is arranged on the bottom. The first connecting plate 3 is screwed to the bottom of the first buffer plate 2, and the second connecting plate 4 is screwed to the four corners of the bottom of the elevator shaft respectively.

[0025] In this embodiment, four first hydraulic buffers 1 are respectively arranged at the four corners of the elevator shaft bottom, which can evenly support the first buffer plate 2. When the car falls on the first buffer plate 2, the force can be evenly applied, and the contact area between the two is large, which is not easy to cause damage to the bottom of the car.

[0026] A rubber pad 11 is fitted on the top of the first buffer plate 2 to further protect the first buffer plate 2 and the bottom of the car and reduce the noise generated when the car falls.

[0027] Sliding guides 5 are fixedly mounted on both sides of the first buffer plate 2. The sliding guides 5 are slidably matched with the elevator guide rails to improve the stability of the first buffer plate 2 when it descends.

[0028] It also includes a second hydraulic buffer 6, the telescopic axis of the second hydraulic buffer 6 is shorter than that of the first hydraulic buffer 1, and a second buffer plate 7 is arranged on the top, and a third connecting plate 8 is arranged on the bottom, and the third connecting plate 8 is screwed to the center of the bottom of the elevator shaft.

[0029] In this embodiment, when a large number of passengers fall in the elevator, the first buffer plate 2 presses the first hydraulic buffer 1 for the first buffer, the telescopic shaft of the first hydraulic buffer 1 continues to descend, and the first buffer plate 2 presses the second hydraulic buffer 6 for the second buffer, thereby achieving double buffering to improve the safety factor.

[0030] The side walls of the first hydraulic buffer 1 and the second hydraulic buffer 6 are both provided with supporting legs 9. There are three supporting legs 9 which are evenly distributed and triangular in shape, so as to improve the supporting strength. A fourth connecting plate 10 is fixedly installed at the bottom of the supporting legs 9, and the fourth connecting plate 10 is screwed to the bottom of the elevator shaft.
