Description

Technical Field

[0001] The present invention relates to the technical field of household elevator shafts, in particular to a backpack type elevator car structure and an installation method. Background Art

[0002] With the improvement of living standards, home elevators and villa elevators are increasingly being used. At present, the commonly used structures in home elevators are backpack frame and gantry frame. Among them, backpack-type home elevators generally use L-shaped backpack frames to support the car. The bottom of the L-shaped backpack frame needs to support the weight of the entire car and passengers. Usually, a combination of profiles is used to make the bottom bracket. Two vertical beams are connected to the rear side of the bottom bracket, and multiple connecting beams are set between the two vertical beams to form an L-shaped backpack frame structure. Compared with the gantry elevator structure, the backpack frame elevator has a higher utilization rate of the shaft space, and the sightseeing area of ​​the car can be larger, so it is more popular with users.

[0003] The structure of the car of the backpack frame elevator and the connection structure with the backpack frame are particularly important. In the existing backpack frame elevator structure, the car top, car bottom and multiple car walls are generally assembled into an integral structure, and then installed on the horizontal support seat of the backpack frame. This car structure is not only troublesome to disassemble when the car side wall needs to be repaired or replaced in the later stage, but also has a large workload and low maintenance efficiency.

[0004] In addition, there are also existing platform elevators that add left and right decorative panels and a car roof to form a car structure. For example, based on the structure of the platform elevator disclosed in patent CN216038077U, left and right side panels are added to the left and right sides of the manned platform, and corresponding car roofs are installed on the top of the left and right side panels and the back panel to form a car with an open front. Although this type of car structure is relatively convenient to install and maintain, the left and right side panels and the back panel are generally only connected and fixed at the corners by L-shaped connectors, and the strength of the connection structure is not high.
