Description

Technical Field

[0001] The utility model relates to the technical field of elevator protection, in particular to a buffer protection device for a villa elevator. Background Art

[0002] In recent years, with the continuous occurrence of elevator accidents, people have paid more and more attention to the safety protection devices of elevators, especially residents in high-end residential areas pay special attention to the safety of villa elevators in daily use;

[0003] In order to improve the safety of elevator use, the Chinese utility model patent with the publication number of "CN220925982U" discloses a buffer protection device for a household elevator, including a shaft and a car, the bottom of the inner surface of the shaft is fixedly connected with a partition, the top of the partition is evenly fixedly connected with a buffer spring, the top of the buffer spring is fixedly connected with a buffer plate, the inner surface of the buffer spring is provided with a damper, and the left and right sides of the bottom of the buffer plate are fixedly connected with a first tooth plate. The utility model can buffer the movement of the car by arranging a buffer spring, a damper and a buffer plate, and can drive the rubber plate to move upward in the process of the buffer plate moving downward by arranging the first tooth plate, a rotating shaft, a gear, a second tooth plate and a top plate, and the rubber plate can be used to block the downward movement of the car, so as to further improve the protection effect of the car falling. By arranging the above structure, it has the advantages of being able to buffer and block the movement of the elevator and reduce the impact force of the elevator falling.

[0004] However, in actual use, we found that the above solution only provides a buffer protection device for the bottom of the elevator shaft. However, in real life, when a malfunction occurs, the car is usually affected by multiple layers of safety protection measures and will not fall to the bottom of the elevator shaft. In this case, people in the car are often more likely to be injured due to the short fall and shaking of the car. Therefore, in order to solve this problem, we need to consider designing a buffer protection device for the villa elevator. Utility Model Content

DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] Reference Figure 1-Figure 5 A buffer protection device for a villa elevator comprises a car 1, a buffer groove 2 is provided at the inner bottom of the car 1, a through hole (not shown) is also provided at the inner bottom of the buffer groove 2, which is connected to the outside by the through hole, a dust screen is provided in the through hole, six dampers 3 are installed at the inner bottom of the buffer groove 2, a support plate 4 is fixedly connected to the upper ends of the six dampers 3, the support plate 4 is slidably connected to the inner wall of the buffer groove 2, a flexible pad 17 is provided at the upper end of the support plate 4, the flexible pad 17 is made of a thin rubber leather material, the corners of the flexible pad 17 are connected to the inner bottom of the car 1 by a sealant, which can effectively prevent dust and other impurities in the car 1 from entering the buffer groove 2 and affecting the actual buffering effect;

[0023] Among them, the inner bottom of the buffer groove 2 is elastically connected to the lower end of the support plate 4 through six first springs 5, the inner bottom of the buffer groove 2 is fixedly connected with a first support block 6, the upper end of the first support block 6 is installed with an elastic airbag 7, and the elastic airbag 7 can further improve the buffering effect, the inner bottom of the buffer groove 2 is fixedly connected with two second support blocks 8, the upper ends of the two second support blocks 8 are both installed with electromagnets 9, and the lower end of the support plate 4 is installed with two permanent magnets 10, the two electromagnets 9 are matched with the corresponding permanent magnets 10, and when the two electromagnets 9 are activated, the two electromagnets 9 will repel the corresponding permanent magnets 10;

[0024] It also includes a conductive mechanism, which is used to trigger and provide electrical energy to the two electromagnets 9. The conductive mechanism includes a first connecting column 11 fixedly connected to the lower end of the support plate 4, and the lower end of the first connecting column 11 is fixedly connected to the limiting plate 12. A rectangular inner groove 15 is provided at the inner bottom of the buffer groove 2, and the rectangular inner groove 15 cooperates with the limiting plate 12. A conductive plate 14 is slidably connected to the first connecting column 11, and the upper end of the conductive plate 14 is elastically connected to the lower end of the support plate 4 through a second spring 13. Two conductive sheets 16 are installed at the upper end of the buffer groove 2, and also includes a power supply not shown in the figure. The conductive sheet 16 on the left is electrically connected to the electromagnet 9 on the left and the positive pole of the power supply in turn, and the conductive sheet 16 on the right is electrically connected to the electromagnet 9 on the right and the negative pole of the power supply in turn. The conductive plate 14 cooperates with the two conductive sheets 16. When the conductive plate 14 moves down and contacts the two conductive sheets 16, the conductive plate 14 will connect the entire circuit to activate the two electromagnets 9.

[0025] In the utility model, when the elevator fails and the car 1 falls briefly in the shaft, the support plate 4 will also move down with the car 1. When the downward movement stops suddenly, the car 1 will stop moving down, and the support plate 4 will continue to move down. In the process of moving down, first, the six first springs 5 ​​cooperate with the six dampers 3 to buffer and reduce the shock of the support plate 4, and then the lower end of the support plate 4 will contact the elastic airbag 7, and the elastic airbag 7 can further buffer the downward movement of the support plate 4. At the same time, when the support plate 4 moves down, it will drive the first connecting column 11 to move down, drive the limit plate 12 to move down, and drive the conductive plate 14 to move down. During the downward movement, the lower end of the conductive plate 14 will contact the two conductive sheets 16 and stop moving downward, while the limit plate 12 moves down into the rectangular inner groove 15 and continues to move downward. At this time, the second spring 13 will be compressed and exert a downward force on the conductive plate 14, ensuring the stable contact between the conductive plate 14 and the two conductive sheets 16. When the conductive plate 14 contacts the two conductive sheets 16, the two electromagnets 9 will be activated, and the two electromagnets 9 will respectively generate repulsive forces with the corresponding permanent magnets 10, thereby further enhancing the buffering effect, thereby effectively reducing the impact on people in the car when an elevator accident occurs;

[0026] It is worth mentioning that since the flexible pad 17 is sealed to the inner bottom of the car 1 by sealant, it effectively prevents dust and other impurities in the car 1 from passing through the gap between the support plate 4 and the buffer groove 2 into the buffer groove 2 and affecting the buffering effect of various components in the buffer groove 2.
