Spiral car-free elevator

Abstract

The application discloses a spiral type car-free elevator, which comprises a circular shaft, a spiral guide rail, a rotating base and a base tray, wherein the lower part of the rotating base is provided with a plurality of guide rail wheels, and the outer side is provided with three electric drive wheels; when the control drive wheels rotate, friction with the wall of the circular shaft is generated, so that the rotating base rotates and ascends or descends on the guide rail; and the electric drive wheels are provided with brake devices, so that the elevator can be stopped at a floor.

Description

Technical Field

[0001] This invention belongs to the field of home elevators, specifically a spiral-type carless elevator. Background Technology

[0002] In the existing technology, the disadvantages of traction-type home elevators are that they have a complex structure, high cost, and require professional maintenance. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of existing technologies and provide a spiral elevator that is simple in structure, inexpensive, energy-saving, and maintenance-free.

[0004] To achieve the above objectives, the technical solution of the spiral carless elevator of the present invention is as follows: it includes a circular shaft, a spiral guide rail, a rotating base and a base tray. The rotating base is provided with multiple guide rail wheels at the bottom and three electric drive wheels on the outer side. When the drive wheels are controlled to rotate, they generate friction with the circular shaft wall, thereby driving the rotating base to rotate and rise or fall on the guide rail.

[0005] The spiral guide rail is spiral-shaped and installed on the well wall.

[0006] The electric drive wheel is made of soft rubber and is equipped with a braking device.

[0007] The rotating base tray is located on the upper part of the rotating base, and a ball bearing is located in the middle.

[0008] The rotating base tray is provided with a cam bearing on its outer side.

[0009] The circular wellbore is equipped with a vertical cam guide groove. When the rotating base rotates up or down, the cam bearing slides up and down within the guide groove, and the base tray does not rotate with the base.

[0010] The base tray is used to carry passengers, and this elevator is a carless design. Attached Figure Description

[0011] Figure 1 This is a schematic diagram of the rotating base of the spiral-type carless elevator of the present invention.

[0012] Figure 2 This is a cross-sectional view of a circular shaft. Detailed Implementation

[0013] To better understand the purpose, structure, and function of this invention, the spiral carless elevator of this invention will be described in further detail below with reference to the accompanying drawings.

[0014] like Figure 1As shown, the spiral carless elevator of the present invention includes a circular shaft (8), a spiral guide rail (7), a guide groove (9), and a guide wheel (5) of a rotating base (4) mounted on the spiral guide rail (7). The drive wheel (6) of the rotating base is in close contact with the circular shaft (8). The drive wheel is controlled to rotate so that the drive wheel (6) generates friction with the inner wall of the shaft, thereby causing the rotating base (4) to rotate and rise or fall on the spiral guide rail (7).

[0015] like Figure 1 As shown, a ball bearing (3) is provided on the top of the rotating base (4), and a car chassis (1) is installed on the ball bearing (3). When the rotating base (4) rotates, the guide wheel (2) on the car chassis (1) is stuck in the guide groove (9) of the shaft and will not rotate with the rotating base (4), but will only rise and fall with the rotating base (4).

[0016] like Figure 1 As shown, the drive wheel (6) rotates forward to rise or reverses to fall according to the control signal, and the leveling brake device is activated.

[0017] It is understood that those skilled in the art will recognize that various changes or equivalent substitutions can be made to these features and embodiments without departing from the spirit and scope of the invention. Furthermore, under the teachings of this invention, modifications can be made to these features and embodiments to adapt to specific circumstances and materials without departing from the spirit and scope of the invention. Therefore, this invention is not limited to the specific embodiments disclosed herein, and all embodiments falling within the scope of the claims of this application are protected by this invention.
