Background technique

The current renovation of old buildings and the acceleration of urbanization have increased the demand for machine room-less elevators. The problem of reducing the noise generated by the vibration of traction machines with elevators commonly used in civil buildings is particularly prominent. Judging from the actual operation effect, it is impossible to fundamentally solve the problem of the noise caused by the traction machine due to force and vibration, which is where this application needs to focus on improvement.

Utility model content

The technical problem to be solved by the utility model is to provide a vibration and noise reduction device for a machine room-less elevator traction machine that reduces noise.

In order to solve the above technical problems, the utility model provides a vibration and noise reduction device for an elevator traction machine without a machine room. The traction machine is installed in the frame of the traction machine. The guide block is set on the guide rail assembly of the traction machine frame and slides up and down along the guide rail assembly. The bottom of the frame guide rail assembly of the traction machine is connected with the load-bearing beam of the traction machine frame, and the top is connected with the tie plate, and the tie plate passes through the connecting angle iron It is connected with the fixed angle iron, and the fixed angle iron is fixedly connected with the hoistway wall. There are traction machine shock absorbing parts above the load-bearing beam of the traction machine frame and below the traction machine frame. Under the guidance of the guide block, the guide rail assembly moves along the frame of the traction machine in the vertical direction. The vibration generated by the traction machine itself is absorbed by the shock absorbing parts of the traction machine and the frame of the traction machine, so as to avoid the jump and transmission between the wire rope and the traction sheave. Noise to the car.

The superior effect of the present utility model is:

1) For the vibration generated by the traction machine and the car during the movement, the utility model prevents the vibration generated by the wire rope from being transmitted to the car, that is, avoids the generation of noise;

2) The operation of the machine room-less elevator produces a good sense of comfort and a good passenger experience.

Detailed ways

Embodiments of the utility model are described in detail below in conjunction with the accompanying drawings.

Fig. 1 and Fig. 2 show the structural diagram of the embodiment of the utility model. As shown in Figures 1 and 2, the utility model provides a vibration and noise reduction device for a machine room-less elevator traction machine. The traction machine 11 is installed in the traction machine frame 4, and the guide rail side of the traction machine frame 4 A plurality of guide blocks 3 are welded, and the guide blocks 3 are set on the traction machine frame guide rail assembly 7 and slide up and down along the guide rail assembly. The bottom of the traction machine frame guide rail assembly 7 is connected with the traction machine frame load beam 1, and the traction machine The top of the frame guide rail assembly 7 is connected to the tie plate 8, the tie plate 8 is connected to the fixed angle iron 6 through the connecting angle iron 5, the fixed angle iron 6 is fixedly connected to the hoistway wall through the expansion bolt 9, and the load-bearing beam of the traction machine frame 1 Above and below the traction machine frame 4 is provided a traction machine shock absorbing part 2, the traction machine 11 is forced to generate vibration, and the traction machine frame 4 is guided by the guide block 3 along the traction machine frame guide rail assembly 7 in the vertical direction. Movement, the vibration generated by the traction machine 11 itself is absorbed by the traction machine shock-absorbing component 2 and the traction machine frame 4, so as to avoid the jump between the wire rope and the traction sheave and the transmission to the car to generate noise.

The load-bearing beam 1 of the frame of the traction machine provides support for the traction machine 11, and bears the self-weight of the traction machine 11 and part of the weight of the car and the counterweight.
