As a result, in practice, the car often shifts and becomes unstable during long-term operation.
[0004] High-speed elevators have higher requirements for stability. When the car often shifts or becomes unstable during long-term operation, the consequences are more serious due to high-speed operation. This makes the maintenance cost of high-speed elevators extremely high and the maintenance cycle extremely short, causing great inconvenience to the using companies. Summary of the invention

The adaptive positioning adjustment structure for the high-speed elevator car can greatly improve the operating stability of the elevator in a low-cost and adaptive manner through a clamping installation structure combined with a rotatable limiting structure. It can not only effectively improve the position stability of the car during operation, but also make it easier to fine-tune the installation position, thereby effectively reducing the maintenance cost of the high-speed elevator and shortening the maintenance cycle of the high-speed elevator.

[0029] The second embodiment of the present invention is substantially the same as the first embodiment, mainly in that the width of the strip groove on the side of the column profile 5 is 1.01 to 1.2 times the width of the limiting wheel assembly 1 .
[0030] Furthermore, the limiting wheel assembly 1 is composed of a limiting roller 101 installed on a limiting shaft 103 via a limiting support bearing 102 , and the limiting shaft 103 is connected to the middle mounting plate 106 via a limiting locking screw 105 .
