Embodiment 1

[0028] Such as figure 1 with figure 2 As shown, a double traction machine elevator, two traction machines 1 are arranged in the machine room above the elevator shaft, and the two traction machines 1 are supported on the load-bearing steel beam 2, and the distance between the traction machine 1 and the load-bearing steel beam 2 is There is a support seat 3 between them, a reel 15 is provided on the traction machine 1, and a tensioner 16 is arranged inside the support seat 3. The steel wire rope goes around the reel 15 and is connected to the car after being tightened by the tensioner 16 to support The lower end of the seat 3 is connected to the load-bearing steel beam 2, and the upper end of the lower end of the supporting seat 3 is connected to the traction machine 1. There are two traction machines 1 in the machine room. When the wire rope of one traction machine 1 is disconnected, due to the other traction Due to the function of machine 1, the car will not fall directly, w...

Embodiment 2

[0035] Such as image 3 As shown, both sides of the traction machine 1 are provided with reels 16, and the support base 3 is provided with two tensioning wheels 16, and the two tensioning wheels 16 correspond to the reels 16 on both sides of the traction machine 1 respectively. After the wire rope on one side of the traction machine 1 breaks, the wire rope on the other side of the traction machine 1 will continue to tighten the car to prevent the car from falling, which is safe and reliable.

Embodiment 3

[0037] Such as Figure 4 As shown, the elevator shaft is provided with a groove 17, the traction machine 1 is installed in the groove 17, the tensioner 16 is located in the elevator shaft, the tensioner 16 is supported in the elevator shaft by the load-bearing steel beam 2, and the outside of the groove 17 is provided with The inspection door 18 installs the traction machine 1 in the groove 17, which can reduce the weight of the load-bearing steel beam 2 and prevent the car from pulling down the load-bearing steel beam 2. The inspection door 18 is convenient for inspection and maintenance of the traction machine 1 without going into the elevator shaft It can be overhauled, and the degree of danger in the overhaul process is reduced.

Abstract

The invention discloses an elevator with double traction machines. According to the elevator with double traction machines, two traction machines are arranged in a machine room above an elevator shaft; the two traction machines are supported on a load-bearing steel beam; a supporting base is arranged between each traction machine and the load-bearing steel beam; reels are arranged on the tractionmachines; a tensioning wheel is arranged in each supporting base; the lower end of the supporting base is connected to the load-bearing steel beam; the upper end of the supporting base is connected tothe traction machine; a wire bunching mechanism is arranged on the load-bearing steel beam; the wire bunching mechanism comprises a horizontal wire bunching groove and a vertical wire bunching groove; arc-shaped plates are arranged on the side faces of the upper end of the vertical wire bunching groove; supporting plates are arranged at the upper end of the vertical wire bunching groove and located at the rear end of the arc-shaped plates; and a roller is arranged between the supporting plates. The two traction machines are supported on the load-bearing steel beam; the two traction machines are arranged in the machine room; and therefore, after the steel wire rope of one traction machine is broken, due to the effect of the other traction machine, the lift car cannot directly fall off, andthe safety of the elevator is improved.

Description

technical field [0001] The invention relates to the technical field of elevators, in particular to an elevator with double traction machines. Background technique [0002] With the development of social economy, more and more residential quarters, hospitals, shopping malls, factories, enterprises, logistics centers, etc. install and use various elevators. In the installation process of these elevators, the installation of the traction machine is particularly important, and the traction machine exists as a power drive system for lifting and lowering the car. [0003] Most of the existing elevators have only one traction machine. When the wire rope breaks, the car will fall from the elevator shaft, causing casualties and greater economic losses. Contents of the invention [0004] The object of the present invention is to solve the above problems, and to provide an elevator with double traction machines. [0005] The technical scheme that the present invention solves its te...
