Problems solved by technology

[0003] For the elevator system, it is necessary to install a driving device on the top of the shaft to drive the car up and down. Most of the existing designs are to install the driving device directly above the car. When the car rises to the top, in order to avoid The device interferes with the car, and the height of the hoistway needs to be increased, which will undoubtedly lead to the difficulty of installation and the increase of installation cost

Embodiment 1

[0031] Such as Figure 1 to Figure 3 Shown, a kind of elevator system comprises: hoistway 11, counterweight guide rail 14 and 15, car guide rail 12 and 13, car 21, counterweight 31, driving device, traction rope (not shown in the figure); The car guide rails 12, 13 form a pair, and the two counterweight guide rails 14, 15 form a pair. The car guide rails 12, 13 and the counterweight guide rails 14, 15 are respectively arranged in the hoistway 11, and the car 21 is arranged in the hoistway 11 and guided by the car guide rails 12 and 13, the car pulleys 22 and 23 are provided on the car 21, the counterweight 31 is arranged in the hoistway 11 and guided by the counterweight guide rails 14 and 15, and the counterweight 31 is provided with There is a counterweight pulley 32; the driving device includes a driving main body 41 and a driving wheel 42 that is transmission-connected with the driving main body 41, and the driving main body 41 is connected on the counterweight guide rails...

Embodiment 2

[0046] Such as Figure 4 As shown, in this embodiment, relative to the connection of the two car guide rails 12, 13, the counterweight guide rails 14 and 15, the driving device, and the counterweight 31 are all close to the back side of the car 21, and the two car guide rails The line connecting the guide rails 12,13 is inclined and intersects the line connecting the two car pulleys 22,23.

Embodiment 3

[0048] Such as Figure 5 As shown, in this embodiment, relative to the connection of the two car guide rails 12, 13, the counterweight guide rails 14 and 15, the driving device, and the counterweight 31 are all close to the front side of the car 21, and the two car guide rails The connecting line of guide rail 12,13 is parallel with the connecting line of two car pulleys 22,23.

Abstract

The invention discloses an elevator system. The elevator system comprises a shaft, cage guide rails, counterweight guide rails, a cage, a counterweight, a driving device and a traction rope, wherein the cage guide rails and the counterweight guide rails are arranged inside the shaft; the cage is arranged inside the shaft and is guided by the cage guide rails; cage pulleys are arranged on the cage; the counterweight is arranged inside the shaft and is guided by the counterweight guide rails; a counterweight pulley is arranged on the counterweight; the driving device comprises a driving main body and a driving wheel in transmission connection with the driving main body; the driving main body is connected with the counterweight guide rails and the cage guide rails through a connecting device; seen down from the shaft, the driving wheel is positioned between a connecting line of the counterweight guide rails and the side wall of the cage; the driving main body is more far from the cage relative to the driving wheel; the traction rope is wound onto the cage pulleys, the driving wheel and the counterweight pulley, and achieves lifting of the cage and the counterweight under the action of the driving wheel. The elevator system can effectively reduce the height of the shaft and solve safety problems caused thereby.

Description

technical field [0001] The invention belongs to the field of elevators, in particular to elevator systems. Background technique [0002] With the increase of high-rise residential and office buildings, the application of elevator systems is becoming more and more extensive. [0003] For the elevator system, it is necessary to install a driving device on the top of the shaft to drive the car up and down. Most of the existing designs are to install the driving device directly above the car. When the car rises to the top, in order to avoid The interference between the device and the car needs to increase the height of the hoistway, which will undoubtedly lead to the difficulty of installation and the increase of installation cost. Contents of the invention [0004] Based on this, the present invention overcomes the defects of the prior art and provides an elevator system. The present invention can effectively reduce the height of the hoistway and solve the safety problems ar...
