Description

Technical Field

[0001] The present application relates to the technical field of crushers, and particularly to a vibration damping device. Background Art

[0002] At present, raw coal needs to go through a multi-stage crushing process from mining to being combusted and utilized. The key equipment is a crusher with high efficiency and high output. In addition to the vibration caused by the operation of the motor, during the material crushing process, the crushing of large pieces of material into small pieces will generate vibrations with different frequencies and amplitudes. After long-term operation, many problems such as bolt loosening and fatigue fracture of the support structure may occur. Reducing the negative impact of the crusher's vibration is of great significance for the safe and stable operation of the crushing equipment.

[0003] Currently, mechanical springs are mostly used as the vibration damping device of the crusher to achieve the vibration damping effect. Specifically, the spring vibration damping device is installed under the mounting seat of the crusher. In this way, the spring vibration damping device is connected in series in the force transmission path, and it is difficult to ensure the installation stability of large crushers with strong vibrations. Moreover, it increases the installation height of the crushing equipment and related matching structures, resulting in an overall increase in the installation position of the crusher. The installation heights of facilities such as the feeder, receiving bin, and supporting steel structure installed in cooperation increase, increasing costs. At the same time, the series installation method of the vibration damping device is not conducive to the installation stiffness. For crushing equipment with a very large mass and high vibration energy, its installation stability is crucial. If the vibration energy is too large and abnormal situations such as large deformation or fracture of the series-installed vibration damping device occur, it may lead to the instability and tipping of the crusher and its attached structures installed above, and the consequences are very serious. In addition, currently, the crusher or other vibration source equipment needs to be lifted before the entire vibration damping base or local vibration damping device can be replaced, and the operation cycle is long. The utility model can replace the vibration damping device without lifting the vibration source equipment. Summary of the Utility Model

[0042] The following refers to Figures 1 to 9 Describe the vibration damping device according to some embodiments of the present application.

[0043] Refer to Figures 1 to 5 As shown, the embodiments of the present application provide a vibration damping device for being installed between a device to be vibration-damped, such as a crusher, and a working platform 1. The vibration damping device includes: a mounting seat 2, a bracket 3, and a vibration damping assembly 4; wherein, the mounting seat 2 is used for being installed on the upper surface of the working platform 1, and the bottom of the device to be vibration-damped is detachably installed on the top of the mounting seat 2; the mounting seat 2 includes a vertical support portion 21, a horizontal support portion 22, and a rib plate 23. The bottom end of the vertical support portion 21 abuts against the upper surface of the working platform 1, and the top end of the vertical support portion 21 is connected to the horizontal support portion 22;

[0044] Along the height direction of the device to be vibration-damped, an installation space 24 is formed between the horizontal support portion 22 and the working platform 1. The rib plate 23, the vibration damping assembly 4, and the bracket 3 are all arranged in the installation space 24, and the rib plate 23 is respectively connected to the vertical support portion 21 and the horizontal support portion 22. The vibration damping assembly 4 is detachably installed on the rib plate 23 through the bracket 3. It can be seen that the bracket 3 is detachably connected to the mounting seat 2, and the vibration damping assembly 4 and the corresponding bracket 3 are detachably connected. In addition, the bracket 3 limits the vibration damping assembly 4 and prevents it from moving during the installation state. If the vibration damping assembly 4 needs to be replaced, the bracket 3 must be disassembled first, then the vibration damping assembly 4 is flattened by applying a compressive force to the upper and lower end cover flanges, then taken out from the gap, replaced, stuffed back, and then the bracket 3 is reinstalled; the bottom end of the vibration damping assembly 4 abuts against the upper surface of the working platform 1, and the top end of the vibration damping assembly 4 passes through the through hole on the horizontal support portion 22 and abuts against the bottom of the device to be vibration-damped.

[0045] In this embodiment, the vibration damping device provided by the present application integrates the vibration damping component 4 on the side of the mounting seat, that is, a parallel structure is formed. Compared with the series structure in the prior art, that is, the vibration damping device needs to be separated from the equipment mounting seat and arranged below the mounting seat. Then, when considering the height of the vibration damping device in equipment installation, the crusher and the upper crushing cavity need to be lifted as a whole by a certain height. If the vibration damping device and the mounting seat of the equipment are integrated together, that is, the parallel structure in the present application is formed, there is no need to consider the impact of this height increase on the upper equipment. Thus, the installation height of large-scale heavy equipment is reduced, its overall stability is better, and the installation heights of facilities such as the feeder, receiving bin, and supporting steel structure installed in cooperation with it are reduced, reducing costs, and the overall stiffness is improved, the overall structure is more stable, the vibration damping device is not easily broken, and there will be no problem of instability and tipping of the crusher and its auxiliary structures. In addition, when there is a problem with the vibration damping component 4, the vibration damping component 4 can be directly replaced without hoisting the equipment to be vibration-damped, which saves time and effort, is safer and more reliable, and saves costs.

[0046] It should be noted that: This vibration damping device is not limited to being applied to crushers, but also to other equipment for vibration damping.

[0047] In an embodiment of the present application, preferably, as Figure 2 and Figure 5 shown, the vibration damping component 4 includes a support column 41, a spring 42, an upper end cover 43, and a lower end cover 44; wherein, the upper end cover 43 is arranged above the top of the support column 41, that is, the upper end cover 43 does not contact the support column 41, and the lower end cover 44 is fixedly installed at the bottom end of the support column 41;

[0048] The spring 42 is sleeved outside the support column 41, and the top end of the spring 42 is fixedly connected to the upper end cover 43, and the bottom end of the spring 42 is fixedly connected to the lower end cover 44. Not limited to this, the following structure can also be adopted, for example: the top end of the spring 42 abuts against the upper end cover 43, and the bottom end of the spring 42 abuts against the lower end cover 44; the top of the upper end cover 43 passes through the through hole on the transverse support part 22 and abuts against the bottom of the equipment to be vibration-damped, and the bottom of the lower end cover 44 abuts against the upper surface of the working platform 1.

[0049] In this embodiment, the support column 41 plays a role in limiting the spring 42. When the spring 42 breaks, the broken spring 42 cannot break away from the support column 41, thus eliminating the possibility that the broken spring 42 will fly off and injure the personnel under the crushing platform under large-amplitude vibration.

[0050] In an embodiment of the present application, preferably, as Figure 5 shown, the vibration damping component 4 further includes a rubber pad 45, and rubber pads 45 are provided on the upper surface of the upper end cover 43 and the lower surface of the lower end cover 44.

[0060] Furthermore, preferably, a limiting step is provided on the outer wall of the support column 41 near its bottom end, and the limiting step can abut against the upper surface of the lower end cap 44.

[0062] In an embodiment of the present application, preferably, as Figure 5 and Figure 6As shown, the bracket 3 includes a support portion 31, a first limiting portion 32, and a second limiting portion 33. Among them, the first limiting portion 32 and the second limiting portion 33 are respectively connected to the top end and the bottom end of the support portion 31 to form a C-shaped structure. The support portion 31 is detachably connected to the vertical support portion 21.

[0063] In this embodiment, the C-shaped bracket 3 can not only support the damping assembly 4, but also play a role in limiting the damping assembly 4.

[0065] In this embodiment, the first limiting portion 32 is used to limit the displacement of the upper end cover 43 in the vertical direction to prevent it from detaching from the top through hole of the mounting seat 2.

[0066] Further, preferably, the first limiting portion 32 is formed with a first arc limiting hole 321 and is disposed around the outer periphery of the upper end cover 43 to increase the limiting area and improve the limiting effect.

[0069] Further, preferably, the second limiting portion 33 is formed with a second arc limiting hole 331 and is disposed around the outer periphery of the lower end cover 44 to increase the limiting area and improve the limiting effect.

[0070] In an embodiment of the present application, preferably, as Figure 9 shown, both the vertical support portion 21 and the horizontal support portion 22 are annular support frames, which have low material costs while ensuring strength and stiffness.

[0071] Further, preferably, a plurality of damping components 4 are provided on both opposite side portions of the vertical support portion 21, and the plurality of damping components 4 on each side portion are sequentially arranged at intervals along the length direction of this side portion, that is, the extending direction.

[0072] In an embodiment of the present application, preferably, as Figure 9 shown, the vertical support portion 21 includes a plurality of vertical plates 211, and the plurality of vertical plates 211 are sequentially enclosed to form an annular frame structure.

[0073] In this embodiment, the vertical plates 211 are assembled into a frame structure, which has low material cost while ensuring strength and stiffness.

[0074] Further, preferably, any two adjacent vertical plates 211 are connected by welding.

[0075] In an embodiment of the present application, preferably, as Figure 9 shown, the transverse support portion 22 includes a plurality of transverse plates 221, and the plurality of transverse plates 221 are sequentially enclosed to form an annular frame.

[0076] In this embodiment, the transverse plates 221 are assembled into a frame structure, which has low material cost while ensuring strength and stiffness.

[0077] Further, preferably, any two adjacent transverse plates 221 are connected by welding.

[0078] Further, preferably, the number of the plurality of transverse plates 221 is equal to that of the plurality of vertical plates 211, and they correspond to each other one by one.

[0079] Further, preferably, the transverse plates 221 and the vertical plates 211 are connected by welding.

[0080] Further, preferably, as Figure 9 shown, the vertical support portion 21, the transverse support portion 22 and the rib plate 23 are welded together, and the overall strength and stiffness are good.

[0081] In an embodiment of the present application, preferably, as Figure 5As shown, the bracket 3 and the rib plate 23 are detachably connected by bolts, namely the first bolt 46, which belongs to a relatively common detachable connection structure, with stable structure, long service life and low cost. In an embodiment of the present application, preferably, the equipment to be vibration-damped is detachably connected to the lateral support portion 22 by bolts, which belongs to a relatively common detachable connection structure, with stable structure, long service life and low cost. Of course, it is not limited to this, and the equipment to be vibration-damped can also be connected to the lateral support portion 22 by means of clamping, etc.

[0082] In an embodiment of the present application, preferably, the mounting seat 2 is connected to the working platform 1, and preferably, the mounting seat 2 and the working platform 1 can be connected by means of welding, bolts, clamping or gluing, etc. Of course, it is not limited to this, and the mounting seat 2 can also be only located on the working platform 1, and there is no connection relationship between the two.

[0083] Combined with the above, the assembly and use process of the vibration damping device provided in the present application is as follows:

[0084] First, pre-install the vibration damping assembly 4, and the specific process is as follows: bond the rubber pads 45 to the upper surface of the upper end cover 43 and the lower surface of the lower end cover 44 respectively, fixedly insert the bottom of the support column 41 into the guide hole of the lower end cover 44, sleeved the spring 42 from above the support column, and snap the lower end of the spring 42 into the lower card slot 441 of the lower end cover 44, place the upper end cover 43 above the spring 42, and snap the spring 42 into the upper card slot 431 of the upper end cover 43. Thus, the pre-installation process of the vibration damping assembly 4 is completed.

[0085] The mounting seat 2 is formed by welding the transverse plate 221, the vertical plate 211 and the rib plate 23 together, and is fixed to the crushing platform to form a box-shaped structure, which ensures the strength and stiffness of the entire mounting seat 2. Apply the force to compress the spring 42 through the first lower flange 434 of the upper end cover 43 and the second upper flange of the lower end cover 44 of the vibration damping assembly 4, so that the vibration damping assembly 4 is compressed to a height that can be installed in the installation space 24, send the vibration damping assembly 4 into the installation space 24 until it is aligned with the through hole of the transverse plate 221 of the mounting seat 2, and loosen the flanges of the upper and lower end covers 44 of the vibration damping assembly 4 to make the vibration damping device rebound naturally. After all the vibration damping assemblies 4 are arranged.

[0086] Assemble the bracket 3 between the vibration damping assembly 4 and the rib plate 23 of the mounting seat 2. In the natural state, the upper and lower bottom surfaces of the bracket 3 abut against the first lower flange 434 at the top of the upper end cover 43 and the second upper flange at the bottom of the lower end cover 44 of the vibration damping assembly 4, and fix the bracket 3 to the rib plate 23 of the mounting seat 2 with bolts. Thus, the installation of the vibration damping assembly 4 is completed.

[0087] After the equipment to be vibration-damped, such as a crusher, is installed above the mounting base 2, under the action of gravity, the vibration-damping component 4 is compressed and pressed tightly against the rubber pad 45. The frictional force between the rubber pad 45 and the crushing platform and the crusher housing prevents the vibration-damping component 4 from moving horizontally.

[0088] Among them, the setting of the support 3 fixes the vertical position of the lower end cover 44 of the vibration-damping component 4. At the same time, the through hole restricts the vibration-damping component 4 in the horizontal direction, and can limit its large-range movement in the horizontal direction in some abnormal vibration cases. When the spring 42 breaks, the upper end cover 43 of the vibration-damping device loses its supporting force and falls under the action of gravity. The distance between the upper surface of the support 3 and the lower surface of the cross plate 221 of the mounting base 2 is less than the total thickness of the first upper flange of the upper end cover 43 of the vibration-damping component 4 and the rubber pad 45, which limits the upper end cover 43 from disengaging from the through hole of the cross plate 221 of the mounting base 2 in terms of spatial position.

[0089] Among them, the setting of the support column 41 makes it impossible for the broken spring 42 to break away from the support column 41 when the spring 42 breaks, thus eliminating the possibility that the broken spring 42 will fly off and injure the personnel under the crushing platform in the case of large-amplitude vibration.

[0090] When the spring 42 of a certain vibration-damping component 4 needs to be replaced, the machine needs to be stopped first. Then, remove the bolts of the support 3 of the vibration-damping component 4 to be replaced and remove the support 3. Cut the support column 41 at the break of the spring 42, remove the broken spring 42 and the support column 41, and take out the upper and lower end covers 44 and the rubber pad 45 of the vibration-damping component 4. Of course, it is not limited to the above steps. The support column 41 can also be cut at multiple places or a compressive force can be applied through the flanges of the upper and lower end covers 44 for quick removal. After the vibration-damping device to be replaced is disassembled, fix the bottom of the support column 41 and insert it into the guiding hole of the lower end cover 44. Slip the spring 42 over the support column 41 from above, and snap the lower end of the spring 42 into the lower card slot 441. Place the upper end cover 43 above the spring 42, and snap the top of the spring 42 into the upper card slot 431 of the upper end cover 43. Apply a compressive force through the first lower flange 434 of the upper end cover 43 and the second upper flange of the lower end cover 44, so that the height of the vibration-damping component 4 can pass through the installation space 24 between the mounting base 2 and the working platform 1, and send the vibration-damping component 4 into the installation space 24 until it is aligned with the through hole of the cross plate 221 of the mounting base 2. Loosen the flanges of the upper and lower end covers 44 of the vibration-damping component 4 to allow the vibration-damping device to rebound naturally, and thus complete the replacement process of the vibration-damping device.

[0091] It can be seen that the vibration damping device adopts a form in which the mounting base 2 below the crusher is arranged in parallel with the vibration damping component 4, which has large stiffness and strength and has a certain vibration damping effect, that is, it has both vibration damping performance and installation stability, and will not cause an increase in the installation height of the crusher. At the same time, the vibration damping components 4 of the present application can be individually disassembled and replaced without disassembling the crusher and its mounting base 2, which is convenient for replacement, saving time, effort and cost.

[0092] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than limiting them; although the present application has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application.
