Maintenance-free safety braking system and braking method for home elevator

Abstract

The invention discloses a maintenance-free safety braking system and a braking method for a home elevator, wherein the safety braking system includes a lifting assembly, two sliding assemblies, two braking assemblies and a buffer assembly, and the braking assembly includes a The elastic plate on the top of the car and the brake piece arranged on the side of the car and connected with the elastic plate, the elastic plate has a deformed state and a free state, and the brake piece has a locked state that restricts the movement of the car and an open state that allows the car to move State: the buffer assembly is arranged at the bottom of the car so that the bottom of the car contacts the ground through the buffer assembly, the buffer assembly has a buffer distance, and the buffer distance is greater than the braking distance. The brake assembly prevents the car and the passengers in the car from being damaged after the wire rope breaks. Finally, the buffer assembly can further prevent the wire rope from being in hard contact with the ground after the wire rope breaks, making it safer to use.

Description

technical field [0001] The invention belongs to the field of home elevators, and in particular relates to a maintenance-free safety braking system and a braking method for home elevators. Background technique [0002] With the continuous improvement of the economic level, people's residential forms are gradually developing towards facilities with larger private spaces such as villas. The storey height of villas is generally designed as two or three floors. The whole equipment structure of the traction elevator is complicated, and it needs to be equipped with a shaft, which will take up a lot of space. Considering the problem of occupied space and the cost of the traction elevator, elevators are not installed in most villas. However, in recent years, with the population of our country As the problem of aging increases, it is very inconvenient for the elderly to go up and down stairs by stairs in villas, and there are potential safety hazards. Therefore, the demand for small h...

Problems solved by technology

[0002] With the continuous improvement of the economic level, people's residential forms are gradually developing towards facilities with larger private spaces such as villas. The storey height of villas is generally designed as two or three floors. The whole equipment structure of the traction elevator is complicated, and it needs to be equipped with a shaft, which will take up a lot of space. Considering the problem of occupied space and the cost of the traction elevator, elevators are not installed in most villas. However, in recent years, with the population of our country With the increase of the aging problem, it is very inconvenient for the elderly to go up and down the stairs in villas, and there are potential safety hazards. Therefore, the demand for small home elevators in the market is becoming more and more urgent.

[0003] In the prior art, small and medium-sized home elevators are generally provided with a vertical guide rail without a shaft between the floors. At this time, the car will have the risk of falling. Although the existing home elevator has a braking device, the braking distance is relatively long. The car will be in contact with the ground, causing danger to the car and the passengers in the car
