Detailed Description
The following detailed description of the preferred embodiments of the present invention will be provided in conjunction with the accompanying drawings, so as to enable those skilled in the art to more easily understand the advantages and features of the present invention, and thereby define the scope of the invention more clearly and clearly.
Referring to fig. 1 to 2, the elevator with different traction ratios in this embodiment includes an elevator shaft 11, a hoisting rope 3, a car 8, a counterweight 9, a traction machine and a traction sheave 1, where the traction machine and the traction sheave are located at the top of the elevator shaft 11, the top of the elevator shaft 11 is provided with a plurality of top return sheaves 6, the top of the top return sheave 6 corresponds to the position of the counterweight 9, the tops of the counterweight 9 and the car 8 are respectively and fixedly provided with a plurality of counterweight return sheaves 10 and a car top return sheave 7, the hoisting rope 3 sequentially bypasses the car top return sheave 7, the traction sheave 1, the counterweight return sheave 10 and the top return sheave 6 along the length direction of the elevator shaft 11, the car 8 and the counterweight 9 are suspended by the hoisting rope 3, and the number of the hoisting rope 3 suspending the counterweight 9 is greater than the number of the hoisting rope 3 suspending the car 8.
When the car rope head assembly 4 is directly fixed on the upper surface of the car 8, the number of the hoisting ropes 3 suspending the car 8 is one, namely the hoisting ratio of the car 8 side is 1: 1, the counterweight rope head combination 5 is directly connected with the counterweight 9, only one counterweight return rope wheel 10 is arranged on the counterweight 9, the number of the hoisting ropes 3 suspending the counterweight 9 is 3, namely, the hoisting ratio of the counterweight 9 side is 3: 1, the whole stroke of the counterweight 9 is one third of the whole stroke of the car 8, so that the moving stroke of the counterweight is reduced, and the using area of an elevator shaft 11 is saved.
When the car rope head combination 4 and the counterweight rope head combination 5 are directly fixed on the top of the elevator shaft 11, the car 8 is provided with two car top return rope wheels 7, at this time, the number of the hoisting ropes 3 suspending the car 8 is two, namely, the traction ratio of the car 8 side is 2: 1, two counterweight return sheaves 10 are provided on the counterweight 9, the number of hoisting ropes 3 suspending the counterweight 9 is 4, that is, the hoisting ratio on the counterweight 9 side is 4: 1, the whole stroke of the counterweight 9 is half of the whole stroke of the car 8, so that the moving stroke of the counterweight is reduced, the using area of an elevator shaft 11 is saved, and in sum, when the number of the hoisting ropes 3 suspending the counterweight 9 is greater than the number of the hoisting ropes 3 suspending the car 8, the moving stroke of the counterweight 9 can be reduced.
