Description

A sprocket-driven continuous elevator

technical field

The invention relates to the mechanical field, in particular to a sprocket-driven continuous elevator.

Background technique

Elevator refers to the permanent transportation equipment that serves several specific floors in the building, and its car runs on at least two rigid rails that are perpendicular to the horizontal plane or less than 15° from the vertical. There is also a step type, and the tread plate is installed on the crawler belt to run continuously, commonly known as an escalator or a moving walk. Fixed lifting equipment serving specified floors. A vertical elevator has a car running between at least two vertical or inclination angles of less than 15° rigid guide rails. The size and structure of the car are convenient for passengers to enter and exit or to load and unload goods. It is customary to use elevator as a general term for vertical transportation in buildings regardless of its driving mode.

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. . The shortcomings of the escalator are that it is not suitable for large-distance transportation in the vertical direction. When the height is too large, the horizontal space required for the inclined installation of the escalator is large. Secondly, if the large-distance transportation is carried out, the open escalator is safe. Poor safety, if accidentally fall, it will fall for a long distance and it is difficult to rescue. Moreover, one pedal of the escalator can only stand two people, and the transportation capacity is limited.

working principle

When passengers need to get on the elevator, they first step on the moving walkway, and the moving sidewalk will transfer the passengers to the electric door. Since the speed of the car and the moving walkway are the same, the passengers and the car are relatively stationary, which can ensure that the passengers can enter the car safely. In the compartment; when passengers get off the elevator, the principle is the same. Passengers first get down on the moving walkway, and then the moving walkway transports the passengers to the ground. The purpose of setting the horizontal shaft in the hoistway is to facilitate passengers to get on and off. During the process of passengers getting on and off, all the cars in the hoistway are still running, and the passengers' getting on and off the elevator has no effect on the operation of the elevator, which saves time.

When the car passes through the horizontal shaft, it transitions smoothly from the arc shaft to the vertical shaft, and the car directly vertically ascends or descends from one floor to another. The cooperation of the arc shaft and the vertical shaft overcomes the escalator The oblique installation requires a large space, which improves the utilization efficiency of the building's interior space and shortens the time from one floor to another.

For the design of the car 2, two inner bearings 18 and two outer bearings 19 are fixed on the outside of the cylinder liner 14. When the outer ring of the bearing rotates, the cylinder liner 14 will not follow the rotation of the outer ring. The inside of the cylindrical tube liner 14 is provided with a standing flat panel 7, which is used for passengers to stand, and the space formed by the standing flat panel 7 below and the cylindrical tube liner 14 wall is filled with heavy objects 8, and the setting of the heavy objects 8 makes The center of gravity of the cylinder liner 14 remains downward, so that the standing flat plate 7 is always on a horizontal plane, and the passenger stands on it as if standing on the floor.

The outer rings of the two inner bearings 18 and the two outer bearings 19 are sprocket rings, so the track is designed as a chain track. Now take the arrangement in the horizontal shaft as an example. The principle in the vertical shaft is the same as that in the horizontal shaft ,No longer.

When the car 2 was installed into the horizontal shaft 11, the upper ends of the sprocket rings of the two outer bearings 19 were engaged with the horizontal fixed chain track 5, and the lower ends of the sprocket rings of the two outer bearings 19 were aligned with the middle of the horizontal movable chain drive track 6. The rows of chains are meshed. At this time, the two inner bearings 18 are in a suspended state. The power of the car comes from the horizontal movable chain drive track 6. The drive sprocket is driven by the motor to rotate, and the drive sprocket drives the three rows of chain rings to rotate. The three rows of chains The ring drives the sprocket ring to rotate, and because the horizontal fixed chain track 5 above the sprocket ring is motionless, the car can move forward.

Since the two ends of the two large-radius fixed chain tracks 9 extend into the horizontal shaft 11 and the vertical shaft 12 respectively, when the car travels to the arc shaft, the sprocket rings of the two inner bearings 18 of the car 2 The lower end will engage with two large-radius fixed chain tracks 9, while the upper end remains suspended; at this time, the sprocket rings of the two outer bearings 19 and the sprocket rings of the two inner bearings 18 on the car are all aligned with the corresponding tracks. After the car has been stably carried out on the four tracks for a period of time, the car reaches the end of the horizontal movable chain drive track 6, and the lower ends of the sprocket rings of the two outer bearings 19 are separated from the horizontal movable chain drive track 6, and the car passes through the two The engagement of the sprocket circle of the first inner bearing 18 and the two large-radius fixed chain tracks 9 continues to advance.

When the car 2 came to the tangent connection between the horizontal shaft 11 and the arc shaft 13, the upper ends of the sprocket rings of the two inner bearings 18 began to engage with the two circumferential chain tracks 10 on the driving runner, and the driving sprocket had The motor drives the rotation, and the two circumferential chain tracks 10 follow the drive sprocket to rotate, and the two circumferential chain tracks 10 drive the sprocket rings of the two inner bearings 18 to rotate. Since the two large-radius fixed chain tracks 9 are stationary, the car move forward.
