Description

Technical Field

[0001] This utility model belongs to the technical field of traction machine accessories, and in particular relates to a traction machine shock absorption device. Background Technology

[0002] As the core power equipment of the elevator system, the stability and reliability of the traction machine are crucial to the overall performance of the elevator. During elevator operation, the traction machine inevitably generates vibration and noise, which not only affects the comfort of the ride, but also may cause equipment components to loosen over time, reduce the service life of the equipment, and even cause safety hazards. Therefore, vibration damping devices are needed to buffer the vibration of the traction machine.

[0003] Currently, existing traction machine vibration damping devices generally use a single spring or rubber pad for damping. However, these devices have the following drawbacks in practical use:

[0004] First, in existing traction machine vibration damping devices, the damping effect of a single spring or rubber pad is limited when faced with large vibrations of the traction machine, and it is difficult to effectively suppress the transmission of vibrations. Second, existing traction machine vibration damping devices lack an effective guiding structure, and when the traction machine is subjected to uneven force, it is easy to tilt, which affects the normal operation of the equipment. In addition, existing traction machine vibration damping devices cannot absorb the noise generated when the traction machine vibrates.

[0005] Therefore, it is essential to invent a shock absorption device for traction machines. Utility Model Content

[0006] To address the above problems, this utility model proposes a shock absorption device for traction machines, and the technical solution used is as follows:

[0007] A traction machine vibration damping device includes a base, an anti-impact mechanism, a pressure plate, a guide mechanism, a sound-absorbing plate, a traction machine mounting plate, and a flexible pad. A plurality of anti-impact mechanisms are evenly fixed to the upper side of the base by bolts, wherein the upper end of each anti-impact mechanism is fixed to the pressure plate by bolts. A plurality of guide mechanisms are evenly fixed between the base and the pressure plate. A sound-absorbing plate is fixed to the upper side of the pressure plate by bolts, wherein the upper side of the sound-absorbing plate is fixed to the traction machine mounting plate by bolts, and a flexible pad is fixed to the upper side of the traction machine mounting plate by bolts.

[0008] Furthermore, the shock-absorbing mechanism includes a first spring plate, a second spring plate, a fixing ring, and a positioning frame. The second spring plate is attached to the upper side of the first spring plate, and the first and second spring plates are mirror images of each other. The middle parts of the first and second spring plates are fixed together by the fixing ring. Positioning frames are rotatably mounted at both ends of the first and second spring plates. The positioning frame on the first spring plate is fixed to the base by bolts, and the positioning frame on the second spring plate is fixed to the lower side of the pressure plate by bolts. With this arrangement, when the traction machine experiences large vibrations, the deformation of the first and second spring plates can buffer the vibrations.

[0009] Furthermore, the fixing ring includes a compression plate, a limiting ring, and a nut. The limiting ring is sleeved on the outer side of the middle portion of the first spring plate and the second spring plate, and both ends of the limiting ring slide through the compression plate, which is fitted against the upper side of the second spring plate. Both ends of the limiting ring are fixed with nuts by thread engagement. This arrangement can fix the middle portion of the first spring plate and the second spring plate together.

[0010] Furthermore, the guiding mechanism includes a sleeve, a sliding column, steel balls, and a shock-absorbing spring. The sleeve is fixed to the upper side of the base by bolts, and several steel balls are rotatably mounted on the inner wall of the sleeve via a ball joint. The sliding column is slidably mounted inside the sleeve via the steel balls. The upper end of the sliding column is fixed to the lower side of the pressure plate by bolts, and a shock-absorbing spring is provided on the lower side of the sliding column. The shock-absorbing spring is movably disposed inside the sleeve. This arrangement can limit the movement direction of the pressure plate, thereby preventing the traction machine from tilting.

[0011] Furthermore, the sound-absorbing panel includes a panel body, honeycomb holes, and latex blocks. The panel body is fixed between the pressure plate and the traction machine mounting plate by bolts, and a number of honeycomb holes are evenly opened through the interior of the panel body. The interior of each honeycomb hole is filled with latex blocks. This arrangement can buffer the small vibrations generated by the traction machine and absorb the noise generated when the traction machine vibrates.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. The anti-impact mechanism of this utility model is designed so that when the traction machine experiences significant vibration, the vibration will cause the first spring plate and the second spring plate to deform accordingly, thereby buffering the vibration.

[0014] 2. The guide mechanism of this utility model can limit the movement direction of the pressure plate when the pressure plate is squeezed by the traction machine under the action of the traction machine, thereby preventing the traction machine from tilting. In addition, the steel balls can reduce the friction between the sliding column and the inner wall of the sleeve.

[0015] 3. The sound-absorbing plate of this utility model can disperse the stress generated by the vibration of the traction machine when the traction machine experiences minor vibration, thereby achieving a vibration reduction effect. Secondly, the latex blocks inside the honeycomb holes can absorb the noise generated by the vibration of the traction machine. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0026] In the description of this utility model, it should be understood that the terms "upper", "middle", "outer", "inner", "around", etc., which indicate orientation or positional relationship, are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0027] Please see Figures 1 to 2 As shown, this utility model is a shock absorption device for a traction machine, including a base 1, an anti-impact mechanism 2, a pressure plate 3, a guide mechanism 4, a sound-absorbing plate 5, a traction machine mounting plate 6, and a flexible pad 7. Several anti-impact mechanisms 2 are evenly fixed to the upper side of the base 1 by bolts, wherein the upper end of the anti-impact mechanism 2 is fixed to the pressure plate 3 by bolts; several guide mechanisms 4 are evenly fixed between the base 1 and the pressure plate 3; the upper side of the pressure plate 3 is fixed to the sound-absorbing plate 5 by bolts, wherein the upper side of the sound-absorbing plate 5 is fixed to the traction machine mounting plate 6 by bolts, and the upper side of the traction machine mounting plate 6 is fixed to the flexible pad 7 by bolts.

[0028] like Figure 3 As shown, the shock-absorbing mechanism 2 includes a first spring plate 21, a second spring plate 22, a fixing ring 23, and a positioning frame 24. The second spring plate 22 is attached to the upper side of the first spring plate 21, and the first spring plate 21 and the second spring plate 22 are mirror images of each other. The middle parts of the first spring plate 21 and the second spring plate 22 are fixed together by the fixing ring 23. Positioning frames 24 are rotatably installed at both ends of the first spring plate 21 and the second spring plate 22. The positioning frames 24 on the first spring plate 21 are fixed to the base 1 by bolts, and the positioning frames 24 on the second spring plate 22 are fixed to the lower side of the pressure plate 3 by bolts. When the traction machine experiences a large vibration, the vibration will be transmitted to the first spring plate 21 and the second spring plate 22 through the pressure plate 3, causing the first spring plate 21 and the second spring plate 22 to deform accordingly, thereby buffering the vibration.

[0029] like Figure 4As shown, the fixing ring 23 includes a pressing plate 231, a limiting ring 232, and a nut 233. The limiting ring 232 is sleeved on the outer side of the middle portion of the first spring plate 21 and the second spring plate 22, and both ends of the limiting ring 232 slide through the pressing plate 231. The pressing plate 231 is fitted to the upper side of the second spring plate 22. Both ends of the limiting ring 232 are fixed with nuts 233 by thread engagement. In use, the pressing force of the nuts 233 on the pressing plate 231 makes the pressing plate 231 and the limiting ring 232 fix the middle portion of the first spring plate 21 and the second spring plate 22 together.

[0030] like Figure 5 As shown, the guide mechanism 4 includes a sleeve 41, a sliding column 42, steel balls 43, and a shock-absorbing spring 44. The sleeve 41 is fixed to the upper side of the base 1 by bolts, and several steel balls 43 are rotatably installed on the inner wall of the sleeve 41 through a ball joint. The sliding column 42 is slidably installed inside the sleeve 41 through the steel balls 43. The upper end of the sliding column 42 is fixed to the lower side of the pressure plate 3 by bolts, and a shock-absorbing spring 44 is provided on the lower side of the sliding column 42. The shock-absorbing spring 44 is movably installed inside the sleeve 41. When the pressure plate 3 is squeezed by the traction machine to compress the anti-impact mechanism 2, the sliding column 42 can slide accordingly inside the sleeve 41, thereby preventing the pressure plate 3 and the traction machine from tilting. Secondly, the setting of the steel balls 43 can reduce the friction between the sliding column 42 and the inner wall of the sleeve 41. In addition, the shock-absorbing spring 44 can improve the reset speed of the pressure plate 3.

[0031] like Figure 6 As shown, the sound-absorbing panel 5 includes a panel body 51, honeycomb holes 52, and latex blocks 53. The panel body 51 is fixed between the pressure plate 3 and the traction machine mounting plate 6 by bolts, and a number of honeycomb holes 52 are evenly opened inside the panel body 51. The inside of each honeycomb hole 52 is filled with latex blocks 53. When the traction machine vibrates, the honeycomb holes 52 in the panel body 51 can disperse the stress generated by the vibration of the traction machine, thereby achieving a vibration reduction effect. In addition, the latex blocks 53 inside the honeycomb holes 52 can absorb the noise generated by the vibration of the traction machine.

[0032] Please see Figure 1-6 As shown, this utility model is a shock absorption device for a traction machine. Its working principle is as follows: During installation, the base 1 is first fixed in the corresponding position with bolts, and then the traction machine is fixed on the traction machine mounting plate 6 with bolts. During use, when the traction machine experiences small vibrations, the sound-absorbing plate 5 and the flexible pad 7 can absorb the vibrations. When the traction machine experiences large vibrations, the anti-impact mechanism 2 can buffer the vibrations. The guide mechanism 4 can limit the movement direction of the traction machine to prevent the traction machine from tilting.
