Description
Technical Field
[0001] This application relates to a traction elevator, belonging to the field of elevator equipment technology. Background Technology
[0002] As an important piece of equipment for improving the quality of life, the noise and vibration levels of home elevators during operation, as well as their installation flexibility, have become the core concerns of users.
[0003] Traditional home traction elevators typically use traction machines fixed to the top load-bearing beam of the shaft via rigid brackets or simple pads. During operation, the vibrations of the traction machine are transmitted directly to the building structure through the rigid connection, generating unpleasant noise and disrupting the peace and quiet of the home.
[0004] Therefore, there is an urgent need in this field for a home traction elevator that can effectively isolate vibration and noise while ensuring operational stability. Utility Model Content
[0005] The purpose of this application is to provide a traction elevator to solve the technical problem of high vibration and noise of traction machines in the prior art.
[0006] The purpose of this application is to achieve the following technical solution: a traction elevator, installed in an elevator shaft, comprising: The car mechanism is installed inside the elevator shaft; A traction mechanism, connected to the car mechanism, drives the car mechanism to move up and down within the elevator shaft; and A counterweight mechanism, connected to the traction mechanism and disposed on both sides of the traction mechanism, is configured to provide counterweight force to the car mechanism. The traction mechanism includes a load-bearing beam installed on the top of the elevator shaft, a shock-absorbing support connecting the load-bearing beam and the top of the elevator shaft, a traction machine installed on the load-bearing beam, and a pulley block connected to the traction machine via a traction rope. The shock-absorbing support is configured to reduce the vibration and noise of the traction machine during operation.

[0008] In one embodiment, the seat includes a first support fixedly installed on the top of the elevator shaft, and a second support sleeved on the first support and slidably connected to the first support, wherein the second support slides relative to the first support to adjust the height of the seat. The shock absorber is installed on the second support.
[0009] In one embodiment, the base further includes a drive member for driving the second support body to slide, the drive member being mounted inside the first support body and having a drive shaft extending out of the first support body to connect with the second support body.
[0010] In one embodiment, the shock absorber is a rubber shock absorber pad.
[0011] In one embodiment, the car mechanism includes a frame slidably installed in the elevator shaft at a preset angle and a car body connected to the frame; The preset angle is in the range of 35°-55°.
[0012] In one embodiment, the preset angle ranges from 40° to 50°.
[0013] In one embodiment, the pulley block includes a first movable pulley connected to the car mechanism, a second movable pulley connected to the counterweight mechanism, and a transmission fixed pulley for changing the direction of the traction rope.
[0014] In one embodiment, the second movable pulley and the transmission fixed pulley are arranged in parallel, and the center line of the second movable pulley and the center line of the transmission fixed pulley coincide or tend to coincide.
[0015] In one embodiment, the traction machine is arranged in parallel with the second movable pulley and the transmission fixed pulley.

The guide angle of the car mechanism is set between 35° and 55°, which allows the guide rails to be arranged diagonally in the car. This provides a structural basis for the car to open at a 90° right angle or open from three sides. At the same time, it maintains the symmetrical force characteristics similar to a gantry frame, ensuring smooth operation and avoiding the off-center load problem of the backpack frame structure.

[0023] Please see Figures 1 to 3 As shown, a traction elevator installed in an elevator shaft 11 in a preferred embodiment of this application is applicable to home elevator scenarios.
[0024] Home traction elevators generally employ either a gantry frame structure or a backpack frame structure. In the gantry frame structure, the car frame is located on both sides of the elevator shaft 11, requiring both sides of the shaft to bear the load to achieve balanced force and smooth operation. Therefore, it occupies a large space in the elevator shaft 11 and can only provide door opening directions on two opposite sides or one side, making it difficult to achieve 90° right-angle door opening or three-sided door opening, thus lacking flexibility.
[0025] The car frame of the backpack-frame structure is located on one side of the elevator shaft 11, requiring the elevator shaft 11 to bear the load on one side. This results in a small space in the elevator shaft 11, which can provide three-sided door opening directions, thus achieving three-door operation. However, due to the cantilever load, there is an inherent off-center load, leading to poor operational stability, rapid wear of guide shoes, and increased noise and vibration over time, affecting comfort and lifespan.
[0026] To solve the above-mentioned technical problems, the traction elevator in this embodiment includes a car mechanism, a traction mechanism and a counterweight mechanism. The car mechanism is installed in the elevator shaft 11. The counterweight mechanism and the car mechanism are respectively connected to the traction mechanism and are respectively arranged on both sides of the traction mechanism. The counterweight mechanism is configured to provide counterweight force to the car mechanism, and the traction mechanism drives the car mechanism to move up and down in the elevator shaft 11.
[0027] Specifically, the car mechanism includes a frame 2 slidably installed in the elevator shaft 11 along a preset angle α, and a car body 1 connected to the frame 2. A first guide rail 6 is provided in the elevator shaft 11, and the frame 2 slides in conjunction with the first guide rail 6 to realize the sliding lifting and lowering of the car mechanism. The preset angle α ranges from 35° to 55°. Preferably, the preset angle α ranges from 40° to 50°. In this embodiment, the preset angle α can be 45°, that is, the frame 2 is installed along the diagonal of the elevator shaft 11 to balance the door opening requirements and the load. Through the above arrangement, a structural foundation is provided for the car body 1 to achieve 90° right-angle door opening or three-sided door opening, while maintaining symmetrical load-bearing characteristics similar to a gantry frame, ensuring smooth operation and avoiding the off-center load problem of a backpack frame structure.
[0028] It is worth noting that the above values include all lower and upper values that increase by one unit from the lower limit to the upper limit, with at least a two-unit interval between any lower value and any higher value.
[0029] As mentioned above, the example range with intervals of 5 does not preclude growth with intervals of appropriate units such as 1, 2, 3, 4, etc. These are merely examples intended to clarify the point, and it can be assumed that all possible combinations of values listed between the minimum and maximum values are explicitly described in this specification in a similar manner.
[0030] The traction mechanism includes a load-bearing beam 5 installed on the top of the elevator shaft 11, a shock-absorbing support 13 connecting the load-bearing beam 5 and the top of the elevator shaft 11, a traction machine 4 installed on the load-bearing beam 5, and a pulley block connected to the traction machine 4 via a traction rope 12. The shock-absorbing support 13 is configured to reduce the vibration and noise of the traction machine 4 during operation.
[0031] Specifically, the vibration damping support 13 includes a base and a vibration damping element 133 installed on the base. The base has at least two height settings to adapt to the height of the load-bearing beam 5. In this embodiment, the vibration damping element 133 is a rubber vibration damping pad, which can effectively isolate the vibration generated during the operation of the traction machine 4, block the solid-borne sound transmission path, significantly reduce the noise pollution caused by elevator operation to the home environment, and improve comfort.
[0032] The seat includes a first support 131 fixedly installed on the top of the elevator shaft 11, and a second support 132 sleeved on and slidably connected to the first support 131. The second support 132 slides relative to the first support 131 to adjust the height of the seat. A shock absorber 133 is installed on the second support 132. By designing the seat of the shock absorber 13 to be height adjustable, it can flexibly adapt to different installation planes on the top of the shaft, compensate for the unevenness of the building structure, greatly facilitate the horizontal alignment of the load-bearing beam 5 and the installation of the entire traction mechanism, and improve installation efficiency and quality.
[0033] The base also includes a driving component for sliding the second support 132. The driving component is installed inside the first support 131 and its drive shaft extends out of the first support 131 to connect with the second support 132. In this embodiment, the driving component can be a linear drive mechanism such as a hydraulic cylinder or a pneumatic cylinder, and is not specifically limited here, but can be determined according to the actual situation.
[0034] The pulley block includes a first movable pulley 8 connected to the car mechanism, a second movable pulley 9 connected to the counterweight mechanism, and a transmission fixed pulley 10 for changing the direction of the traction rope 12. The second movable pulley 9 and the transmission fixed pulley 10 are arranged in parallel, and the center line of the second movable pulley 9 and the center line of the transmission fixed pulley 10 coincide or nearly coincide, thereby reducing the space occupied by the traction elevator and making the overall traction elevator more compact. Furthermore, the traction machine 4 is arranged in parallel with the second movable pulley 9 and the transmission fixed pulley 10, which allows it to enter the rope groove of the transmission fixed pulley 10353 with minimal deflection angle, and then smoothly guide the rope from the transmission fixed pulley 10 to the second movable pulley 9, greatly reducing the additional wear and vibration of the traction rope 12 and ensuring smooth and efficient transmission.
[0035] The counterweight mechanism includes a counterweight 3, which can slide and move up and down within the elevator shaft 11. Therefore, a second guide rail 7 is also provided within the elevator shaft 11, and the second guide rail 7 slides in conjunction with the counterweight 3 to achieve the sliding and lifting of the counterweight 3. In this embodiment, the counterweight 3 has a conventional structure and will not be described in detail here.
[0036] In summary: By setting up a special vibration damping support 13 to connect the load-bearing beam 5 and the top of the shaft, the vibration generated during the operation of the traction machine 4 is effectively isolated, the solid-borne sound transmission path is blocked, the noise pollution caused by elevator operation to the home environment is significantly reduced, and the comfort level is improved. The damping bearing 13 is designed with an adjustable height, which can flexibly adapt to the installation plane of different shaft tops, compensate for the unevenness of the building structure, greatly facilitate the horizontal alignment of the bearing beam 5 and the installation of the entire traction mechanism, and improve installation efficiency and quality. The guide angle of the car mechanism is set between 35° and 55°, which allows the guide rails to be arranged diagonally in the car. This provides a structural basis for the car to open at a 90° right angle or open from three sides. At the same time, it maintains the symmetrical force characteristics similar to a gantry frame, ensuring smooth operation and avoiding the off-center load problem of the backpack frame structure.
[0037] The above is only one specific implementation of this application, and any other improvements made based on the concept of this application shall be considered within the scope of protection of this application.
