[0045] According to the exemplary embodiment of the present invention, please refer to Figure 1-Figure 6 , provides an installation device for a car top wheel of an elevator, comprising a base 1 and two connecting parts 3. The bottom of the base 1 extends into the interior of the upper beam 2 of the elevator. The longitudinal cross-section of the base 1 is roughly U-shaped. The middle part of the base 1 has a recess 11 extending downward in the height direction. A reinforcing component 12 is provided inside the base 1 and below the recess 11 to increase the rigidity of the base 1. The two connecting parts 3 are detachably mounted on the two ends of the base 1 extending in the lateral direction, respectively, and are suitable for mounting two car top wheels 4 on the base 1 respectively. The rigidity of the connecting part 3 is less than that of the base 1, so as to reduce the resonance of the connecting part 3 and the base 1 during the operation of the elevator.

[0046] In this embodiment, a base 1 and connecting parts 3 detachably mounted at both ends of the base 1 extending in the lateral direction are provided. A reinforcing assembly 12 is provided inside the base 1 and below the recess 11 to increase the rigidity of the base 1, so that the rigidity of the connecting part 3 is less than that of the base 1, so as to reduce the resonance between the connecting part 3 and the base 1 during the operation of the elevator, thereby reducing the noise. Among them, the recess 11 provided in the middle of the base 1 and extending downward in the height direction forms an inspection channel for maintenance personnel to inspect.

[0047] In some exemplary embodiments, referring to Figure 6 The reinforcement assembly 12 includes at least one reinforcement member 121 disposed between two sides of the base 1 facing each other.

[0048] In some exemplary embodiments, referring to Figure 4 as well as Figure 6 The minimum distance between each reinforcing member 121 and the adjacent car top wheel 4 is greater than 3 mm.

[0049] In some exemplary embodiments, referring to Figure 4-Figure 6 The base 1 includes a base plate 13 and two support plates 14. The base plate 13 extends in the transverse direction. The two support plates 14 are respectively connected to the two sides of the base plate 13 extending in the longitudinal direction and extend in the height direction, and a recess 141 extending downward in the height direction is provided in the middle of each support plate 14. Among them, the reinforcing member 121 includes two reinforcing plates 1211, and the two ends and the bottom of each reinforcing plate 1211 extending in the longitudinal direction are respectively connected to the two support plates 14 and the base plate 13, and the car top wheel 4 is installed between the two support plates 14 through the connecting portion 3.

[0050] In this embodiment, a reinforcing member 121 including two reinforcing plates 1211 is arranged between the two sides of the base 1 facing each other, which effectively improves the rigidity of the base 1 and has a simple structure. It reduces the resonance between the connecting part 3 and the base 1 during the operation of the elevator and improves the stability and service life of the installation device.

[0051] It should be noted that, in this embodiment, the base 1 is obtained by welding a base plate 13 and two support plates 14 .

[0052] In some exemplary embodiments, referring to Figure 2-Figure 3The installation device also includes two installation covers 5 and a first vibration reduction assembly 51. The two installation covers 5 are respectively covered on the car top wheel 4, and the lower part of each installation cover 5 forms a vertically bent edge 52. The first vibration reduction assembly 51 is suitable for installing the bent edge 52 of the installation cover 5 on the upper beam 2 or the base 1 to reduce the vibration noise between the installation cover 5 and the upper beam 2 during the operation of the elevator. Among them, when the first vibration reduction assembly 51 is suitable for installing the bent edge 52 of the installation cover 5 on the upper beam 2, the vibration generated on the installation cover 5 is directly transmitted to the upper beam 2 during the operation of the elevator. In other words, the vibration generated on the installation cover 5 is prevented from being transmitted to the base 1, so as to reduce the vibration noise between the installation cover 5 and the upper beam 2 during the operation of the elevator. When the first vibration reduction assembly 51 is suitable for installing the bent edge 52 of the mounting cover 5 on the base 1, the vibration between the mounting cover 5 and the base 1 is reduced during the operation of the elevator, thereby reducing the vibration received by the upper beam 2, which is generated by the mounting cover 5 and transmitted through the base 1, so as to reduce the vibration noise between the mounting cover 5 and the upper beam 2 during the operation of the elevator.

[0053] It should be noted that, in this embodiment, each mounting cover 5 is mounted on the upper beam 2 through two first vibration reduction components 51. The two first vibration reduction components 51 are respectively mounted on two curved edges 52 extending from the lower portion of the mounting cover 5. In this way, the noise generated during the operation of the car top wheel 4 can be effectively reduced to improve the riding comfort of the elevator.

The at least one first vibration damping pad 511 is installed on one side of the curved edge 52 of the mounting cover 5. One end of the fastener 512 passes through the curved edge 52 of the mounting cover 5, the first vibration damping pad 511 and the upper beam 2 to install the first vibration damping pad 511 between the curved edge 52 of the mounting cover 5 and the upper beam 2.

[0055] It should be noted that each first vibration-damping assembly 51 includes two first vibration-damping pads 511 , which are respectively installed on two opposite sides of the bent edge 52 .

[0056] In some exemplary embodiments, referring to Figure 1-Figure 2 A plurality of second vibration-damping pads 15 for mounting with the upper beam 2 are also arranged on the outside of the two opposite sides of the base 1, so as to reduce the vibration noise between the base 1 and the upper beam 2 during the operation of the elevator.

[0057] It should be noted that, in this embodiment, two second vibration-damping pads 15 are respectively arranged on each side of the outside of the base 1, and the second vibration-damping pads 15 installed on opposite sides of the outside of the base 1 are symmetrically arranged about the base 1. The two second vibration-damping pads 15 installed on one side of the outside of the base 1 are respectively arranged on both sides extending in the lateral direction below the recess 11 of the base 1.

[0058] In some exemplary embodiments, referring to Figure 4-Figure 6 The installation device further includes a dust cover 6, which is inserted into the recess 11, and the two ends extending in the lateral direction are respectively connected to the top of the recess 11 to prevent dust from entering the interior of the installation device.

[0059] In some exemplary embodiments, referring to Figure 4-Figure 5 Each connecting portion 3 includes two connecting plates 31 and a rotating shaft 32. The two connecting plates 31 are respectively installed on the outsides of the two supporting plates 14. The rotating shaft 32 passes through the centers of the two connecting plates 31, the two supporting plates 14 and the car top wheel 4 in the longitudinal direction to install the car top wheel 4 between the two supporting plates 14.

[0060] In some exemplary embodiments, referring to Figure 4-Figure 5 The connecting portion 3 further includes a first rope-blocking rod 33 and a second rope-blocking rod 34. The first rope-blocking rod 33 extends in the longitudinal direction, and its two ends are respectively connected to the outer ends of the two connecting plates 31 to limit the displacement of the cable 41 wound on the car top wheel 4 in the lateral direction during the rotation of the car top wheel 4. The second rope-blocking rod 34 extends in the longitudinal direction and is installed below the car top wheel 4. Its two ends are respectively connected to the two supporting plates 14 to limit the displacement of the cable 41 wound on the car top wheel 4 in the height direction during the rotation of the car top wheel 4.

[0061] According to the exemplary embodiment of the present invention, please refer to Figure 1 as well as Figure 4 , an upper beam assembly for an elevator is provided, comprising an upper beam 2, a mounting device for a car top wheel of an elevator as described in the above embodiment, and two car top wheels 4. The upper beam 2 is mounted on the top of the elevator car. The bottom of the mounting device for a car top wheel of an elevator as described in the above embodiment extends into the interior of the upper beam 2. The two car top wheels 4 are mounted inside the mounting device to mount the car top wheels 4 on the upper beam 2.

[0062] In this embodiment, the installation device is installed above the upper beam 2, and the bottom of the installation device extends into the interior of the upper beam 2, and the car top wheel 4 is embedded in the interior of the upper beam 2, which can effectively reduce the top floor height and reduce the bending of the cable 41, and effectively improve the stress condition of the upper beam 2. Furthermore, the overall structure of the upper beam assembly of this embodiment is safe and reliable, with low cost, and is suitable for popularization and use.

[0063] In some exemplary embodiments, referring to Figure 1-Figure 2 At least one second vibration damping assembly 21 is installed at the bottom of the upper beam 2. Each second vibration damping assembly 21 includes a third vibration damping pad 211 and at least one connecting rod 212. The third vibration damping pad 211 extends along a plane parallel to the bottom of the upper beam 2. Each connecting rod 212 extends in the height direction, one end of which extends from the bottom of the upper beam 2 and the bottom of the base 1 of the mounting device, and the other end is connected to the third vibration damping pad 211, so as to clamp the third vibration damping pad 211 between the bottom of the upper beam 2 and the top of the elevator car, and reduce the vibration generated by the car top wheel 4 from being transmitted to the car through the upper beam 2 during the operation of the elevator.

[0064] It should be noted that, in this embodiment, two second vibration reduction assemblies 21 are sequentially arranged at the bottom of the upper beam 2 along the longitudinal direction.

[0066] Further, refer to Figure 7 , the main frequency distribution range in the existing elevator car is usually 100-600Hz. The upper beam assembly including the base 1 provided with the reinforcement assembly 12 of this embodiment is installed on the elevator car, and the modal density can be controlled to less than 0.02 / Hz in the range of 100-600Hz. Compared with the existing upper beam assembly, its modal density is significantly reduced.

[0067] Furthermore, the upper beam assembly of the present embodiment can effectively reduce the noise generated during the rotation of the car top wheel 4, improve the structural rigidity, and improve the working reliability and service life of the upper beam assembly when the elevator is running. It has the advantages of simple structure, reasonable arrangement, light weight, and low cost.

[0068] In addition, the base 1 is separated from the connection part 3, and the base 1 adopts a high-rigidity design to reduce the surface vibration speed of the structure and improve the radiation of noise energy. The connection part 3 includes a first rope-blocking rod 33, a second rope-blocking rod 34 and a connecting plate 31, and the connection part 3 adopts a low-rigidity and lightweight design, and is connected to the upper beam 2 through a first vibration reduction component 51, so as to avoid resonance and sound generation between the base 1 and the connection part 3 due to the vibration conduction of the upper beam 2 during the operation of the elevator. Compared with the existing upper beam assembly, the upper beam assembly of this embodiment can reduce the total radiation energy of noise while reducing the weight of the structure, thereby improving the comfort of the elevator.
