Description

Technical Field

[0001] This utility model relates to the field of passenger elevator technology, specifically to an ultra-quiet passenger elevator with noise protection at the contact point between the car and the guide rail. Background Technology

[0002] A passenger elevator is an elevator specifically designed to transport passengers. Powered by an electric motor, it is equipped with a box-shaped car and safety features, and runs between rigid guide rails in multi-story buildings. Passenger elevators are commonly used in high-traffic areas such as airports, hotels, office buildings, and large shopping malls. These locations require elevators with comprehensive safety features and aesthetically pleasing designs to ensure passenger comfort and safety. To improve passenger transport efficiency, a passenger elevator is needed; however, existing passenger elevators still have the following shortcomings:

[0003] When existing passenger elevators are in use, most passenger elevators generate significant wind noise during operation, and the elevator's own movement also produces significant mechanical noise, which can easily cause discomfort symptoms such as tinnitus in passengers, affecting the comfort of passengers riding the elevator, and resulting in a decrease in the practicality and efficiency of passenger elevators.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an ultra-quiet passenger elevator with soundproof protection at the contact point between the car and the guide rail, comprising a shaft wall, a composite sound insulation felt, and a ball bearing guide rail. The inner side of the shaft wall is provided with polyester fiber sound-absorbing cotton, and a mounting frame is installed at the middle of the inner side of the shaft wall.

[0006] Furthermore, the polyester fiber sound-absorbing cotton is horizontally distributed on the outer side of the well wall, and the polyester fiber sound-absorbing cotton is fixedly connected to the well wall by an adhesive.

[0007] Furthermore, the mounting bracket and the mounting back plate are arranged perpendicularly, and the mounting back plate is fixedly connected to the mounting bracket by bolts.

[0008] Furthermore, the outer side of the composite sound insulation felt is horizontally distributed with the outer side of the mounting back plate, and the composite sound insulation felt is fixedly connected to the mounting back plate by an adhesive.

[0009] Furthermore, the external dimensions of the ball guide rail are adapted to the internal dimensions of the ball block, and the ball block and the ball guide rail are slidably connected.

[0010] Furthermore, rubber pads and sound-absorbing panels are respectively provided on the upper and lower sides of the honeycomb sound-absorbing panel, and the honeycomb sound-absorbing panel is disposed and confined between the rubber pads and the sound-absorbing panels.

[0013] This utility model provides an ultra-quiet passenger elevator with noise protection at the contact point between the car and the guide rail, which has the following beneficial effects:

[0014] 1. This utility model, through the setting of ball bearing guide rails, enables the use of ultra-quiet passenger elevators with silent protection at the contact point between the car and the guide rails. The ball bearing guide rollers are fixedly installed by installing a back plate, and the ball bearing blocks are installed on the outside of the ball bearing guide rails. By using noise-reducing materials and an improved connection structure, the ball bearing guide rails effectively reduce friction noise and vibration noise between the wheels and the guide rails, resulting in extremely low noise during operation. This reduces the mechanical noise of the car body when moving, and improves the overall practicality and efficiency of the ultra-quiet passenger elevator.

[0015] 2. This utility model, through the installation of honeycomb sound-absorbing panels, enables the use of ultra-quiet passenger elevators with silent protection at the contact point between the car and the guide rails. The outer and inner wall panels form the main body of the car wall, and the rubber pads absorb impact while providing a certain degree of sound insulation. The honeycomb sound-absorbing panels absorb sound through their honeycomb structure, reducing noise and reverberation. The sound-absorbing panels also have flame-retardant and heat-insulating properties while absorbing sound, and the polycarbonate panels can reduce heat transfer. Thus, while reducing noise inside the elevator, the thermal conductivity is also reduced, making the air conditioning inside the elevator more effective and improving the overall practicality and efficiency of the passenger elevator.

The sides and the outer side of the mounting back plate 4 are horizontally distributed, and the composite sound insulation felt 5 is fixedly connected to the mounting back plate 4 by adhesive.

By adopting noise reduction materials and improved connection structure, the ball guide rail 6 effectively reduces the friction noise and vibration noise between the wheel and the guide rail, making the noise of the equipment extremely low during operation, thereby reducing the mechanical noise of the car body 8 when moving, and improving the overall practicality and efficiency of the ultra-quiet passenger elevator.

[0022] like Figures 1 to 3As shown, an outer wall panel 9 is provided on the outer side of the interior of the car body 8, and a rubber pad 10 is provided on the inner side of the outer wall panel 9. A honeycomb sound-absorbing panel 11 is provided on the inner side of the rubber pad 10, and a sound-absorbing panel 12 is provided on the inner side of the honeycomb sound-absorbing panel 11.

The sound-absorbing panel 12 is fixedly installed outside the honeycomb sound-absorbing panel 11. The sound-absorbing panel 12 has flame-retardant and heat-insulating properties while absorbing sound. The polycarbonate panel 13 can reduce heat transfer. Thus, the elevator interior is reduced in terms of noise reduction and thermal conductivity, making the air conditioning inside the elevator more effective and improving the overall practicality and efficiency of the passenger elevator.
