[0003] However, for the deficiencies of vertical elevators, firstly, the car lifts up and down in the vertical shaft. If the safety system breaks down, it will easily cause the car to fall from a tall building, causing casualties; Only one car is running. For example, when waiting on the first floor, it is necessary to wait for the elevator car to complete the upward transportation task first, and then descend to carry out the second upward transportation task. The waiting time is long, and the ability to arrive at any time cannot be achieved....

[0036] The lower end of the outer gear ring of the second travel bearing 13 meshes with another bottom rack rail 12, the upper end of the outer gear ring of the second travel bearing 13 meshes with the lower end of the third transition gear 20, and the upper end of the third transition gear 20 meshes with the other top gear The rail 4 meshes, one side of the fourth transition gear 24 meshes with the outer gear ring of the second traveling bearing 13, and the other side meshes with the outer gear ring of the second traveling bearing 13 of the other car 2,

[0037] The front cylindrical end of the car 2 is the entrance and exit of the passenger getting on and off the elevator. The three corners of the tripod 16 are respectively connected to the center of the cylindrical end of the back of the car 2, the center of the first transition gear 18, and the first through a rotating pair. The center of the second transition gear 19; the two ends of the first arc-shaped connecting rod 27 pass through the center of the rotating pair and the third transition gear 20 and the center of the fourth transition gear 24, respectively. Both ends of the first connecting rod 29 pass The rotating pair is connected at the center of the first transition gear 18 and the center of the third transition gear 20, and the two ends of the second connecting rod 28 are respectively fixedly connected to the center of the second transition gear 19 and the center of the fourth transition gear 24 , The first drive gear 25 is fixedly mounted on the second connecting rod 28, the second drive gear 26 is fixedly mounted on the motor shaft, and the second drive gear 26 is kneaded with the first drive gear 25.

[0038] A plurality of cars 2 are continuously installed in the hoistway 3. The two ends of the car connecting rod 17 are respectively connected to the center of the cylindrical end of the cylinder liner 15 of one car 2 and the adjacent car 2 through a rotating pair. The second transition gear 19 is at the center of the circle.

[0039] Further, a door is provided at the entrance and exit end of the cylindrical inner liner 15 of the car 2.

[0040] Further, a standing plate 7 is provided inside the cylindrical inner liner 15, and the space formed by the lower part of the standing plate 7 and the wall surface of the cylindrical inner liner 15 is filled with a weight 8.

[0041] Further, on the floor 1 of the horizontal hoistway 23, a moving sidewalk 30 with the same magnitude and direction as the running speed of the car is provided.

[0042] Further, it also includes a second arc-shaped connecting rod 10. The two ends of the second arc-shaped connecting rod 10 are respectively connected to the center of the third transition gear 20 of one car 2 and another adjacent car 2 through a rotating pair. The center of the fourth transition gear 24.

[0043] working principle

[0044] When passengers need to get on the elevator, they should step on the moving sidewalk 30 first. The moving sidewalk 30 transports the passengers to the electric door. Since the speed of the car 2 and the moving sidewalk 30 are the same, the passengers and the car 2 are relatively stationary, which can ensure Passengers enter the car 2 safely; when the passengers get off the elevator, the principle is the same. The passengers first get down on the moving walkway 30, and then the moving walkway 30 transports the passengers to the ground. The purpose of setting up the 23 part of the horizontal hoistway in hoistway 3 is to facilitate passengers getting on and off. During the passengers getting on and off, all the cars 2 in hoistway 3 still keep running. Passengers’ up and down elevators have no effect on the elevator operation, saving time. .

[0045] When the car 2 passes through the horizontal hoistway, it transitions smoothly from the arc hoistway 22 to the vertical hoistway 21. The car 2 directly rises or descends from one floor to another. The arc hoistway 22 and the vertical hoistway 21 The cooperation overcomes the problem of large space required for inclined installation of escalators, improves the utilization efficiency of the building's indoor space, and shortens the time from one floor to another.

[0046] For the design of the car 2, the first traveling bearing 14 and the second traveling bearing 13 are fixed on the outer side of the cylindrical inner liner 15. When the outer ring of the bearing rotates, the cylindrical inner liner 15 will not rotate with the outer ring, and at the same time The cylindrical inner liner 15 is provided with a standing plate 7 which is used for the standing of passengers. The space formed by the standing plate 7 and the wall surface of the cylindrical inner liner 15 is filled with a weight 8. The arrangement of the weight 8 makes The center of gravity of the cylindrical inner liner 15 is kept downward, so that the standing plate 7 is always on a horizontal surface, and passengers stand on it as if standing on the floor.

[0047] During operation, the motor drives the second drive gear to rotate 26, the second drive gear 26 drives the first drive gear 25 to rotate, the first drive gear 25 drives the second link to rotate 28, and the second link 28 is fixed at both ends of the second link. The transition gear 19 and the fourth transition gear 24 also follow the second connecting rod 28 to rotate. The second transition gear 19 and the fourth transition gear 24 drive the first traveling bearing 14 and the second traveling bearing of two adjacent cars through a meshing relationship. 13 rotates in the same direction, so that the car 2 continues to travel. The tripod 16, the first arc-shaped connecting rod 27, the second arc-shaped connecting rod 10, and the first connecting rod 29 play the role of connection and support. The first transition gear 18 and the third transition gear 20 enable the first traveling bearing 14 and the second traveling shaft 13 to smoothly travel between the top rack rail 4 and the bottom rack rail 12.
