Pit-free brake device for home elevator

Abstract

The invention discloses a pit-free brake device for a home elevator. The pit-free brake device comprises a car, T-shaped guide rails positioned on two sides of the car, guide shoes arranged on the car, a support plate and a brake component, wherein the car moves along the T-shaped guide rails through the guide shoes, the bottom of the car can be in contact with the ground to support the car through the ground, a supporting plate naturally droops to enable a movable connecting piece to be in a first connecting state, and the supporting plate moves towards the bottom of the lift car to enable the movable connecting piece to be in a second connecting state; and the brake assembly comprises a brake switch and a brake part electrically connected with the brake switch, when the movable connecting part is in the second connecting state, the brake switch is in a triggering state, and the brake switch in the triggering state limits the car to move towards the supporting plate through the brakepart. For a home elevator, the pit-free brake device can respond to smaller deformation, the brake speed is higher, the brake distance is shorter, the stability of the brake switch is better, and theelevator is safer during operation.

Description

technical field [0001] The invention belongs to the field of home elevators, and in particular relates to a bottomless pit braking device 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 home elevators in the market is...

[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] Because the overall height of small and medium-sized domestic elevators in the prior art is generally low, the braking link of the domestic elevator is particularly important when an emergency occurs, especially for a domestic elevator without a bottom pit, because the car is directly connected to the elevator. Ground contact, although it will not have a great impact on the structure of the house, it is also necessary to ensure the environment around the car to avoid rolling sundries, infants or pets at the bottom of the car, because the above situation is relative to the entire car. As far as the bottom of the car is concerned, it occupies a small volume, so it is not easy to be detected and the braking link cannot be triggered in time, which is likely to cause danger
