Technical Field
[0001] This invention relates to the field of motor vibration reduction technology, and in particular to a motor vibration reduction structure and installation method for a lifting device. Background Technology
[0002] A traction machine is a hoisting device used in elevators, and it mainly includes components such as a frame, motor, brake, gearbox, and traction sheave. Currently, in situations without a machine room, the frame of the traction machine is usually fixed to guide rails on the top or side of the shaft.
[0003] To achieve vibration isolation and noise reduction for the traction machine motor, vibration damping pads are generally installed at the mounting points of the traction machine frame and guide rails. During installation, the traction sheave is usually mounted closer to the guide rail, resulting in a greater load-bearing capacity on the side of the vibration damping pad closer to the guide rail than on the side farther away. This uneven load distribution can easily lead to excessive localized compression deformation and poor vibration damping effect. Summary of the Invention
[0004] To help ensure the vibration reduction effect, the present invention provides a motor vibration reduction structure and installation method for a lifting device.

The second shock-absorbing pad group is located on the side of the traction machine frame away from the guide rail. The hardness of the first shock-absorbing pad group is higher than that of the second shock-absorbing pad group.
[0006] Preferably, the first damping pad group includes a plurality of first damping pads, and the second damping pad group includes a plurality of second damping pads, wherein the plurality of first damping pads and second damping pads are located between the traction machine frame and the first mounting frame.

[0011] Preferably, two support platforms are slidably arranged on the main frame in the horizontal direction. The two support platforms are respectively used to abut against the bottom walls on both sides of the traction machine frame. The main frame is provided with an adjustment component for adjusting the two support platforms to move closer or further apart. When the mating frame is installed and fixed with the main frame, the two support platforms are detached from the traction machine frame.
[0012] Preferably, the adjustment assembly includes a bidirectional screw rotatably mounted on the main frame and a transmission component mounted on the mating frame. The rotation axis of the bidirectional screw is parallel to the sliding direction of the two support platforms. The two support platforms are respectively threaded onto the two ends of the bidirectional screw.

This helps to make the compression amounts of the first and second damping pad sets more consistent, thus ensuring the damping effect to a certain extent. Attached Figure Description

[0021] The following combination Figures 1-4 The present invention will be described in further detail below.
[0022] Example 1:
[0023] This invention discloses a motor vibration damping structure for a lifting device. (Refer to...) Figure 1The motor vibration damping structure of the hoisting device includes a first mounting frame 1, a traction machine 3, a first damping pad group and a second damping pad group. The first mounting frame 1 is fixedly mounted on the guide rail 2 inside the shaft by multiple bolts. The guide rail 2 is fixed to the top of the shaft in the vertical direction. The traction machine 3 is fixedly mounted on the first mounting frame 1, and the traction wheel of the traction machine 3 is located on the side close to the guide rail 2.
[0024] Reference Figure 1 The first shock-absorbing pad group is set between the first mounting frame 1 and the traction machine 3 frame. The first shock-absorbing pad group is located on the side of the traction machine 3 frame closer to the guide rail 2. The second shock-absorbing pad group is set between the first mounting frame 1 and the traction machine 3 frame. The second shock-absorbing pad group is located on the side of the traction machine 3 frame away from the guide rail 2. The hardness of the first shock-absorbing pad group is higher than that of the second shock-absorbing pad group.
[0025] During the operation of the traction machine 3, the first and second damping pad groups separate the traction machine 3 from the first mounting frame 1, avoiding hard contact. This helps reduce vibration transmission between the first mounting frame 1 and the traction machine 3. By designing the hardness of the first damping pad group on the heavy-load side to be higher than that of the second damping pad group on the light-load side, the deformation of the first damping pad group under heavy pressure will not be excessive, while the second damping pad group can generate a suitable amount of compression under lighter pressure. This helps to make the compression amounts of the first and second damping pad groups more consistent, thus ensuring the damping effect to a certain extent. Specifically, the hardness of the first and second damping pad groups can be obtained through calculation and experimentation based on the center of gravity distribution of the traction machine 3, which will not be elaborated here.
[0026] Reference Figure 1 Furthermore, the first shock-absorbing pad group includes multiple first shock-absorbing pads 4. Since the traction machine 3 frame has placement feet 17 on both sides, in this embodiment of the invention, the first shock-absorbing pads 4 correspond one-to-one with the placement feet 17, and the first shock-absorbing pads 4 are located on the side of the corresponding placement foot 17 closer to the guide rail 2. The second shock-absorbing pad group includes multiple second shock-absorbing pads 5. In this embodiment of the invention, the second shock-absorbing pads 5 also correspond one-to-one with the placement feet 17, and the second shock-absorbing pads 5 are located on the side of the corresponding placement foot 17 away from the guide rail 2. There is a certain gap between the first shock-absorbing pads 4 and the second shock-absorbing pads 5 under the same placement foot 17. The first shock-absorbing pads 4 and the second shock-absorbing pads 5 are both clamped between the corresponding placement foot 17 and the first mounting frame 1, thereby avoiding hard contact between the first mounting frame 1 and the traction machine 3. The hardness of the first shock-absorbing pads 4 is greater than that of the second shock-absorbing pads 5. Both the first shock-absorbing pads 4 and the second shock-absorbing pads 5 are made of high-damping rubber pads.
[0027] Reference Figure 1 and Figure 2To ensure vibration damping and installation stability, both the first damping pad 4 and the second damping pad 5 have rectangular cross-sections, with both length and width exceeding their thickness. During installation, a spiral is used to sequentially pass through the placement foot 17 of the traction machine 3 frame, the first damping pad 4 or the second damping pad 5, and the first mounting bracket 1. Flat washers, spring washers, and double nuts are then connected to the bolts, thereby securing the traction machine 3 to the first mounting bracket 1. The first damping pad 4 and the second damping pad 5 effectively dampen vibrations.
[0028] Reference Figure 2 Furthermore, the first mounting bracket 1 has an integrally formed limiting protrusion 6, which corresponds to the second damping pad 5. Specifically, each second damping pad 5 corresponds to two limiting protrusions 6. A limiting groove 7 is formed on the second damping pad 5, and the limiting groove 7 corresponds one-to-one with the limiting protrusion 6. The limiting protrusion 6 and the limiting groove 7 on the corresponding second damping pad 5 are engaged and cooperated. The depth of the limiting groove 7 is greater than the height of the limiting protrusion 6.
[0029] When the second damping pad 5 is installed, the limiting groove 7 on the second damping pad 5 is engaged with the corresponding limiting protrusion 6. Since the hardness of the second damping pad 5 is less than that of the first damping pad 4, the engagement of the limiting protrusion 6 and the limiting groove 7 can limit the horizontal displacement of the second damping pad 5 during vibration, which helps to make the horizontal deformation of the second damping pad 5 close to that of the first damping pad 4.
[0030] Reference Figure 1 and Figure 2 To further improve the installation stability of the traction machine 3, the motor vibration damping structure also includes a second mounting bracket 8. The second mounting bracket 8 is fixed to the guide rail 2 by multiple bolts and aligned with the upper end of the traction machine 3. A bracket 9 is fixed on the traction machine 3 by bolts. The bracket 9 is connected to the second mounting bracket 8. A third vibration damping pad 10 is provided between the bracket 9 and the second mounting bracket 8.
[0031] Reference Figure 1 and Figure 2 Specifically, multiple bolts are sequentially passed through the bracket 9, the third damping pad 10, and the second mounting bracket 8, and then secured with nuts to achieve a fixed connection. The third damping pad 10 corresponds one-to-one with the bolts on the bracket 9. The placement of the third damping pad 10 separates the second mounting bracket 8 and the bracket 9, avoiding hard contact and helping to reduce vibration transmission between the second mounting bracket 8 and the bracket 9 on the traction machine 3. This ensures effective vibration damping while strengthening the installation strength of the traction machine 3.
[0032] The implementation principle of the motor vibration damping structure in Embodiment 1 of the present invention is as follows: During the operation of the traction machine 3, the first damping pad 4 and the second damping pad 5 can connect the first mounting frame 1 and the frame of the traction machine 3 separately, and the third damping pad 10 can connect the second mounting frame 8 and the bracket 9 separately, thereby reducing the vibration transmission between the first mounting frame 1 and the second mounting frame 8 and the traction machine 3 respectively, and absorbing vibration energy to achieve the effect of vibration damping; By designing the hardness of the first damping pad 4 on the heavy load side to be higher than the hardness of the second damping pad 5 on the light load side, the present invention can ensure that the deformation of the first damping pad 4 under heavy pressure is not too large, and the second damping pad 5 can also generate a suitable amount of compression under light pressure, thereby helping to make the compression of the first damping pad 4 and the second damping pad 5 tend to be consistent. Through the cooperation of the limiting protrusion 6 and the limiting groove 7, the horizontal displacement of the second damping pad 5 during vibration can be limited, which helps to make the horizontal deformation of the second damping pad 5 close to the horizontal deformation of the first damping pad 4, thereby ensuring the vibration damping effect to a certain extent.
[0033] Embodiment 1 of the present invention also discloses a method for installing a motor vibration damping structure of a lifting device. The method for installing the motor vibration damping structure of the lifting device described above includes the following steps: Step 1: Install the first mounting bracket 1 onto the guide rail 2 inside the shaft using bolts; Step 2: Place the two first damping pads 4 of the first damping pad group at the two ends of the upper surface of the first mounting frame 1 near the guide rail 2, and place the two second damping pads 5 of the second damping pad group at the two ends of the upper surface of the first mounting frame 1 away from the guide rail 2. Step 3: Next, hoist the traction machine 3 and place the two placement feet 17 of the traction machine 3 frame on the first shock-absorbing pads 4 and the second shock-absorbing pads 5 at both ends of the first mounting frame 1, with the traction wheel of the traction machine 3 facing one side of the guide rail 2. Step 4: Connect the placement feet 17 of the traction machine 3, the first shock-absorbing pad 4 or the second shock-absorbing pad 5, and the first mounting bracket 1 in sequence using bolts and nuts; Step 5: Clamp the third damping pad 10 between the second mounting frame 8 and the bracket 9. Connect the second mounting frame 8, the third damping pad 10 and the bracket 9 in sequence with bolts. Then connect the bracket 9 to the frame of the traction machine 3 with bolts. Finally, install the second mounting frame 8 on the guide rail 2 with bolts.
[0034] Example 2:
[0035] Reference Figure 3The difference between this embodiment and Embodiment 1 is that the first mounting frame 1 includes a main frame 101 and a mating frame 102. The main frame 101 is fixedly mounted on the guide rail 2 by multiple bolts. The cross-section of the main frame 101 is T-shaped. The mating frame 102 is detachably connected to the main frame 101. Specifically, the mating frame 102 is U-shaped. The recess of the mating frame 102 engages with the protrusion of the main frame 101. The two ends of the mating frame 102 correspond to the two placement feet 17 of the traction machine 3, respectively. The first shock-absorbing pad group and the second shock-absorbing pad group are clamped and connected between the upper surface of the mating frame 102 and the frame of the traction machine 3. The mating frame 102 and the placement feet 17 are fixed by bolts and nuts. The first shock-absorbing pad group and the second shock-absorbing pad group connect the mating frame 102 and the placement feet 17 with a gap. The main frame 101 and the placement feet 17 of the traction machine 3 are not in contact. The limiting protrusion 6 (refer to...) Figure 2 It is integrally formed on the upper surface of the mating frame 102.
[0036] Reference Figure 3 To facilitate the fixed connection between the main frame 101 and the mating frame 102, multiple connecting bolts 11 are installed on the main frame 101 from top to bottom. Each connecting bolt 11 is vertically oriented. The mating frame 102 has through holes (not shown in the figure) for the connecting bolts 11 to pass through, with each through hole corresponding to a connecting bolt 11. A locking nut 12 is threaded onto each connecting bolt 11, and the locking nut 12 abuts against the bottom wall of the mating frame 102. To improve connection stability, double locking nuts 12 can be used for locking, and flat washers and spring washers can be placed between the connecting bolts 11 and the main frame 101, and between the locking nuts 12 and the mating frame 102.
[0037] The main frame 101 and the mating frame 102 are fixedly connected by connecting bolts 11, thereby realizing the detachable connection between the mating frame 102 and the main frame 101. At the same time, when the mating frame 102 is removed from the main frame 101, it moves in the vertical direction.
[0038] Reference Figure 3 and Figure 4Two support platforms 13 are horizontally slidably mounted on the main frame 101, located between two placement feet 17. The sliding direction of the support platforms 13 is parallel to the arrangement direction of the two placement feet 17. The upper surface of the support platforms 13 is flush with the upper surface of the first shock-absorbing pad 4. The two support platforms 13 are respectively used to abut against the bottom wall of the two placement feet 17 of the traction machine 3 frame. At the same time, there is a certain space between the upper surface of the main frame 101 and the traction machine 3, so that the support platforms 13 will not interfere with the traction machine 3. To improve the sliding effect of the support platforms 13, the support platforms 13 are L-shaped. The main frame 101 is provided with a sliding groove 18 that slides with the lower end of the support platform 13. The cross-section of the sliding groove 18 is dovetail-shaped or T-shaped, so that the support platform 13 will not detach from the main frame 101. The main frame 101 is equipped with an adjustment component for adjusting the two support platforms 13 to move closer or further apart. When the mating frame 102 is installed and fixed to the main frame 101, the two support platforms 13 are detached from the two placement feet 17 of the traction machine 3 frame, and the distance between the support platform 13 and the corresponding placement foot 17 is less than 1mm. When the mating frame 102 and the placement foot 17 are fixed, the distance between the two first damping pads 4 and the two second damping pads 5 on the same side are both greater than the distance between the two placement feet 17 on the same side, so that the support of the support platform 13 to the placement foot 17 will not interfere with the first damping pads 4 and the second damping pads 5.
[0039] When the mounting bracket 102 is fixed to the main frame 101 and the traction machine 3 is installed, the two support platforms 13 are detached from the two placement feet 17 of the traction machine 3 frame. At this time, there is no vibration transmission between the traction machine 3 and the main frame 101 through the support platforms 13, which helps to ensure the vibration damping effect. When it is necessary to replace the first vibration damping pad 4 and the second vibration damping pad 5, remove the locking nut 12 from the connecting bolt 11, remove the bolt between the placement feet 17 and the mounting bracket 102, and move the mounting bracket 102 downward away from the traction machine. The machine 3, through the adjustment component, drives the two support platforms 13 to move away from each other, so that the two support platforms 13 support the two placement feet 17 of the traction machine 3 respectively. In this way, with the cooperation of the second mounting frame 8 or with the use of external support, the position of the traction machine 3 is maintained. The cooperating frame 102 drives the first shock-absorbing pad 4 and the second shock-absorbing pad 5 downward away from the traction machine 3, so that enough space can be left for the replacement of the first shock-absorbing pad 4 and the second shock-absorbing pad 5 without moving the traction machine 3, which can greatly improve the replacement efficiency and reduce the equipment investment for replacement.
[0040] Reference Figure 3 and Figure 4To facilitate adjustment of the two support platforms 13 towards or away from each other, the adjustment assembly includes a bidirectional screw 14 and a transmission component. The bidirectional screw 14 is rotatably mounted on the main frame 101. Specifically, the bidirectional screw 14 can be rotatably mounted on the upper surface of the main frame 101 via a support plate, or it can be rotatably mounted inside the main frame 101 so that the support platform 13 abuts against the upper surface of the main frame 101, thereby increasing the support strength of the support platform 13. The rotation axis of the bidirectional screw 14 is parallel to the sliding direction of the two support platforms 13. The two support platforms 13 are respectively threaded onto the two ends of the bidirectional screw 14. The transmission component is mounted on the mating frame 102. The transmission component is used to drive the bidirectional screw 14 to rotate so that the support platform 13 is closer to the bottom wall of the traction machine 3 placement foot 17 when the mating frame 102 is moved away from the main frame 101. In other embodiments, the adjustment assembly may be designed to include only a bidirectional screw 14, which is rotatably mounted on the main frame 101. A handle is fixed to one end of the bidirectional screw 14 located outside the main frame 101, so that the operator can manually rotate the bidirectional screw 14 to adjust the position of the support platform 13. This allows the support platform 13 to be moved to abut against the bottom wall of the placement foot 17 before the locking nut 12 and the bolts between the mounting bracket 102 and the placement foot 17 are removed.
[0041] Reference Figure 3 and Figure 4 To facilitate the rotation of the bidirectional screw 14 when the mating frame 102 is moved away from the main frame 101, causing the support platform 13 to move closer to the bottom wall of the traction machine 3's placement foot 17, the transmission components include a rack 15 and a gear 16. The rack 15 is fixed on the mating frame 102 and is arranged vertically. The main frame 101 has a through hole (not shown in the figure) for the rack 15 to slide through. The gear 16 is fixedly sleeved on the bidirectional screw 14 and meshes with the rack 15. When the rack 15 moves downward, the gear 16 drives the bidirectional screw 14 to rotate, causing the support platform 13 to move closer to the traction machine 3's placement foot 17.
[0042] The implementation principle of Embodiment 2 of the present invention is as follows: When the mounting frame 102 is installed and fixed with the main frame 101, and the traction machine 3 is installed, the two support platforms 13 are disengaged from the two placement feet 17 of the traction machine 3 frame, and the gear 16 and the rack 15 are meshed. At this time, when the traction machine 3 is working, there will be no vibration transmission between the traction machine 3 and the main frame 101 through the support platforms 13, which helps to ensure the shock absorption effect.
[0043] When it is necessary to replace the first damping pad 4 and the second damping pad 5, remove the locking nut 12 from the connecting bolt 11, remove the bolt between the mounting bracket 102 and the placement foot 17, and then move the mounting bracket 102 downward away from the traction machine 3. During the downward movement of the mounting bracket 102, the rack 15 moves downward synchronously, and the rack 15 drives the gear 16 to rotate, causing the bidirectional screw 14 to drive the two support platforms 13 away from each other. The two support platforms 13 immediately abut against the bottom wall of the corresponding placement foot 17, thereby supporting the two placement feet of the traction machine 3. 17. With the cooperation of the support platform 13 and the second mounting frame 8, or with the use of external support, the position of the traction machine 3 is maintained. The mounting frame 102 drives the first damping pad 4 and the second damping pad 5 downward away from the traction machine 3. After leaving a certain space, the operator can replace the first damping pad 4 and the second damping pad 5. In this process, there is no need for the operator to rotate the bidirectional screw 14 while moving the mounting frame 102 downward, nor is there a need to move the position of the traction machine 3. This can greatly improve the replacement efficiency and reduce the equipment investment for replacement.
[0044] The above are all preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, all equivalent changes made in accordance with the structure, shape and principle of the present invention should be covered within the scope of protection of the present invention.
