Cars that are leveled by their own weight

Abstract

The invention provides an elevator car capable of adjusting levelness through dead weight and belongs to the technical field of elevators. The elevator car comprises a car seat, an outer car body and an inner passenger car body. The front side and the rear side of the lower portion of the car seat are each provided with a pair of car seat rollers. The bottom of the outer car body is fixed to the car seat at the position corresponding to the position above the car seat. The inner passenger car body is located on the car seat at the position corresponding to the interior of the outer car body. The elevator car is characterized in that the center of the upper portion of the front side of the car seat and the center of the upper portion of the rear side of the car seat are each provided with a bearing seat cavity, and bearing seats are arranged corresponding to the bearing seat cavities; a dead weight balance box matching cavity is formed in the upper portion of the car seat, a dead weight balance box is fixedly arranged at the bottom of the inner passenger car body, and the dead weight balance box and the dead weight balance box matching cavity are matched; the center of the upper portion of the front side of the dead weight balance box and the center of the upper portion of the rear side of the dead weight balance box are each fixedly provided with a dead weight balance box shaft, and the dead weight balance box shafts correspond to the bearing seats and are supported by the bearing seats. The structure is simplified, manufacture and installation are convenient, the daily management and protection difficulty is reduced, and cost is reduced; high reliability is achieved.

Description

technical field [0001] The invention belongs to the technical field of elevators, and in particular relates to a car that uses its own weight to adjust the level. Background technique [0002] The aforementioned elevators mainly refer to sightseeing elevators, but are not absolutely limited to sightseeing elevators. As the industry knows, the slopes in natural scenic spots are often zigzag and undulating, and the rails for elevators can only be laid according to the situation, but the cars running along the rails must be kept level at all times, otherwise people will be indebted. A sense of comfort. Furthermore, as is known in the industry, when the car is empty, its levelness can be fully reflected, that is, the car floor will not tilt, but when the passengers are concentrated on one side of the car or due to the weight difference of many passengers. Making the car floor difficult to level and out of level, although usually slight, can create discomfort for sensitive occu...

Problems solved by technology

[0003] In the published Chinese patent literature, it can be seen that all the technical information aimed at keeping the car level is typical. For example, the authorized announcement number CN203306882U recommends "a device for automatically leveling the car". Although this patent can reflect the 0011th paragraph of the description However, there are the following shortcomings: First, due to the need to keep the car level with the help of additional mechanisms, the structural system of the additional mechanism such as adjusting the level control box, hydraulic pump and hydraulic cylinder, so the car is not a real sense. Self-adjustment; Second, due to the need to use components such as hydraulic cylinders, the reliability is relatively low, because once the hydraulic cylinders and components such as level sensors fail, it is difficult for the car to achieve balance (level); Third, As mentioned above, due to the need for additional mechanisms, the structure is complex, which is not conducive to production and installation, nor is it convenient for daily management and maintenance.
