Domestic lift

Abstract

The invention discloses a domestic lift comprising a lift car, a backpack frame, a safety tongs triggering device and a safety protective device. The backpack frame is connected to a lift guide rail in a sliding mode and used for fixing the lift car. The safety tongs triggering device is installed on the backpack frame. The safety protective device is installed at the upper end of the lift car or installed at the bottom of a lift shaft. The domestic lift is simple in structure and high in safety performance and occupies a small shaft space.

Description

technical field [0001] The invention relates to the field of elevators, in particular to a home elevator. Background technique [0002] Existing home elevators have the following problems: [0003] 1. During installation, it is necessary to fix the car wall from the outside of the car. However, due to the small size of the home elevator shaft, it is very inconvenient to install from the outside, and it cannot be disassembled after the installation is completed. When the car wall needs to be replaced, it cannot be replaced, nor can it be redecorated; 2. The existing elevator safety gear trigger device is a speed limiter, but because the speed limiter is large in size, it needs to occupy more space in the shaft, and the household Elevators are often arranged in a narrow well. If the speed limiter is still used as the safety gear trigger device, the depth or height of the well will be higher, which will increase the difficulty of setting up the well. 3. The elevator needs to...

[0003] 1. During installation, it is necessary to fix the car wall from the outside of the car. However, due to the small size of the home elevator shaft, it is extremely inconvenient to install from the outside, and it cannot be disassembled after the installation is completed.

When the car wall needs to be replaced, it cannot be replaced, nor can it be redecorated; 2. The existing elevator safety gear trigger device is a speed limiter, but because the speed limiter is large in size, it needs to occupy more space in the shaft, and the household Elevators are often arranged in a narrow well. If the speed limiter is still used as the safety gear trigger device, the depth or height of the well will be higher, which will increase the difficulty of setting up the well. 3. The elevator needs to be maintained every year. Entering the well and located above or below the elevator car, in order to ensure the personal safety of the staff, it is necessary to install a protective device at the bottom of the well or on the top of the car, but because the bottom of the well of the home elevator is shallow, the protective device cannot occupy too much of the well Therefore, how to design a protection device that can ensure the safety of the staff during maintenance / repair without occupying the hoistway space has become an urgent problem to be solved at present; The frame is mainly composed of a straight beam connected to the guide rail and a bracket vertically connected to the lower end of the straight beam.

The car is installed on the upper end of the bracket, and all the weight of the car is borne by the bracket, so the stress on the connection between the bracket and the straight beam and the guide shoes installed at the bottom is also relatively large, which will reduce the service life of the elevator; The frame is located at the bottom of the car, which occupies a large space at the lower end of the shaft. It is necessary to deepen the depth of the pit of the shaft to meet the requirements of the elevator installation, which brings a lot of trouble to the installation of the elevator shaft, especially for the elevator installed on the ground upstairs.

Therefore it is necessary to design a car frame that does not occupy the depth of the shaft pit. At present, there is a car suspension elevator, such as the elevator disclosed in ZL200610141861.7. Bearing, the stress at the connection between the frame arm and the load-bearing frame is relatively concentrated. In order to improve the strength of the connection, it is necessary to increase the size of the frame arm and improve its material strength, so its production cost is high and the hoistway takes up a lot of space
