Description

Vibration isolation device and application thereof

The invention belongs to the field of vibration and noise control, and particularly relates to a vibration isolating device for reducing the adverse effects caused by vibrations and noises emitted during the operation of a rail vehicle or reducing the vibration of building components and equipment. Background technique

Vibration and noise are recognized as the most widespread public hazard. It not only affects and destroys transportation, buildings and equipment, but also directly harms the human body. Therefore, vibration and noise reduction has become a topic of great concern in the field of environmental protection in recent years. Among the existing vibration and noise reduction technologies, the most successful application practices in the fields of rail transit and equipment vibration isolation are component floating technology, typical tracked bed floating technology and equipment foundation floating technology, etc., which have high vibration isolation efficiency. , stable work performance, has become the consensus in the industry. In order to facilitate installation and maintenance, the vibration isolation device has a large number of built-in type when the floating member is used, especially in the field of rail transportation, and the application of the built-in vibration isolation device is relatively common. The Chinese patent No. ZL2004100354411 discloses a built-in vibration isolating device. The coupling sleeve of the vibration isolating device is arranged in the floating plate, and the supporting block fixedly arranged on the coupling sleeve is supported as a direct force component during operation. On the spring isolator, the related parts are prone to fatigue damage, open welding and rust after long-term use. However, since the coupling sleeve is integrated with the floating plate, it cannot be replaced directly. It is also very difficult to be limited by the location and the internal space of the coupling sleeve. At the same time, in order to repair and replace the spring isolator at any time, the traditional built-in vibration isolation device adopts the technical solution that the spring isolator can be directly taken out through the through hole on the coupling sleeve, which requires that the through hole size must be slightly larger than The size of the spring isolator, so that the size of the coupling sleeve is correspondingly larger, which takes up more space and is not conducive to cost and transportation. Summary of the invention

SUMMARY OF THE INVENTION An object of the present invention is to overcome the above-mentioned drawbacks and to provide an vibration isolating device which can take out a support block for maintenance and replacement at any time and its application.

The cross-sectional shape of the joint portion of the boom and the support block is preferably circular from the viewpoint of easy processing, but in consideration of the fact that the circle is easy to rotate during use, if the limit is not effective, the hook may fail. Therefore, it is possible to process the cross-sectional shape of the mating portion of the boom and the support block into a square, a rectangle or a regular hexagon. Of course, the above shapes are mainly selected from the aspects of easy processing, easy positioning, and the like, and many other shapes such as a triangle shape and a pentagon shape are also feasible from the viewpoint of function.

The swingable boom is hingedly disposed between the support block and the support member is provided with a locking device for the boom. In order to ensure the reliability of the hook, for the rotatable or moving boom, a corresponding locking device can also be provided on the support stop. The locking device is a fastening member, a pin, a fastener, a wedge or a chain provided between the support block and the boom. In order to facilitate the connection, an auxiliary structure such as an ear plate is sometimes added to the support block. After the boom is attached to the vibration-isolating member, the position of the hanger is locked by the locking device to ensure that the two are always in an effectively hooked state, which is safe and reliable.

In order to more conveniently adjust the height and level of the vibration isolating member from above the vibration isolating member, a gasket may be disposed between the spring isolator and the support stopper, and the top center of the gasket is provided with a jacking through hole. In order to smoothly adjust the number or total thickness of the spacers from above, the central opening and shape of the support and lift blocks should be compatible with the size of the spacers, and the spacers can at least overlap with the support stops to achieve misalignment. In order to directly insert or remove the spring isolator from above without removing the support block, the central opening and shape of the support block and the jacking block should be compatible with the size of the spring isolator, and the spring is vibration-proof. The upper top surface of the device can be misaligned with at least the support stop.

The block is hooked to the shoulder. In order to ensure the effective connection between the boom and the vibration-isolating member, a limiting device can be arranged at the shoulder of the vibration-isolating member and the hanging block to ensure a relatively stable position between the two, and the limit is limited. The device may be a limiting block or a limiting slot provided on the shoulder.

Since the invention can directly adjust the height and the level of the vibration-isolating member by using the boom, the gasket does not need to be used for jacking, so the upper top plate and the support block of the spring isolator can be integrated into one body, so that the product The structure is simpler and more compact, and the production cost will be further reduced.

Embodiment 1

As shown in FIG. 1 and FIG. 1 , the vibration isolating device of the present invention comprises a support block 1 and a spring isolator 2 , and the spring isolator 1 is located below the support block 1 , wherein the spring isolator 1 is composed of an upper top plate 2 a , The spring 2b, the lower top plate 2c, the liquid damping 2d, the damper cylinder 2e, and the dust cover 2f are formed. The support block 1 is provided with four rotatable booms 3, and the lower part of the boom 3 is horizontally disposed with an outwardly extending hooking block 4. The rotatable boom 3 is arranged through the support stop 1 and is provided with a threaded structure on the upper part and fitted with a lock nut 5.

As shown in FIG. 3, the vibration isolating member 6 is a floating plate of a floating track bed. When applied, the support block 1 and the spring isolator 2 are sequentially placed in the reserved through holes of the floating plate 6, reserved. The through holes are arranged in a stepped shape to constitute a shoulder B for hooking. Loosen the lock nut 5 until the hitch stop 4 is slightly below the shoulder B. Rotating the boom 3 so that the hitch stop 4 is directly under the shoulder, and the symmetrical lock nut 5 is alternately or simultaneously tightened by the tool, so that the hitch stop 4 and the shoulder B are hooked until the float The dispensing weight of the plate 6 is loaded on the spring isolator 2 to complete a loading. Repeatedly, the spring isolators 2 in all the reserved through holes on the floating plate 6 are sequentially loaded in batches until the floating plate 6 leaves the base surface 8 and finally reaches the predetermined height, and the jacking is completed, as shown in the figure. 4 is shown. In this way, the vibration of the floating plate caused by the exciting force is transmitted to the spring isolator through the shoulder, the hanging block and the supporting block, After the attenuation of the spring isolator, it is transmitted to the foundation and then spreads to the surroundings. Most of the vibration energy has been absorbed by the spring isolator, thus effectively reducing the adverse effects of vibration on surrounding buildings, personnel, equipment, and the like. After the lifting is completed, the height and level of the floating plate 6 can be adjusted by adjusting the position of the lock nut 5, and if necessary, a washer can be provided under the lock nut (common technical solution, not shown) for adjustment. To enlarge the stroke of the boom.

In order to prevent horizontal displacement of the spring isolator, an anti-skid pad 7 having a high friction coefficient is disposed between the spring isolator 1 and the support block 1 and between the spring isolator 2 and the base 8. To prevent dust, sewage, or other debris from falling into the reserved through hole, a dust cover 9 is disposed above the reserved through hole.

This embodiment is described only in the case where four booms 3 and four hooking blocks 4 are provided. In practical applications, the number of booms and hooking blocks can be increased or decreased according to the space and load requirements, but Generally, at least two should be set. In order to ensure the stability of the support, it is better to use not less than three.

By adjusting the length of the boom, the vibration isolating device of the present invention can be applied to floating plates of various thicknesses. Of course, based on the above principle, the vibration isolating device of the present invention can also be applied to a building floor, a equipment foundation, and the like, and can obtain a good buffer and vibration isolation effect. For a small vibration-isolating member to be isolated, if the reserved through-hole is set as a stepped hole for the hook to have a great influence on its own strength, the stepped hole structure may not be used, and the hanging stop and the reserved pass may be used. The same effect can be achieved by directly hooking the lower surface of the vibration-isolating member around the hole. The vibration isolation device of the invention has simple lifting operation, simple and compact product structure, saves materials, reduces production cost, and has greatly improved economical and applicability compared with existing products.

Compared with the prior art, once the support block is severely corroded or damaged or the spring isolator is abnormal, the vibration isolating device of the present invention can take out the damaged component at any time for repair and replacement, due to the use of the boom and the hanging block, The force-receiving part of the vibration-isolating member is moved down greatly, which is beneficial to protect the vibration-isolating member and prolong its service life.

Embodiment 2

In order to facilitate the direct lifting of the vibration-isolating member from above and to directly mount the spring isolator from above, the vibration isolating device of the present invention as shown in FIGS. 5 and 6 is different from the first embodiment in that the spacer 10 is added. The gasket 10 is interposed between the spring isolator 2 and the support block 1, which can pass through the central hole of the support block and form a misalignment with the support block, and the support block 1 and the spacer 10 and the spring The size of the vibration isolator 2 corresponds to the center hole. In order to facilitate the jacking operation, a jacking block 11 is provided between the lock nuts 5. When used in the track floating plate, as shown in FIG. 7, a reserved through hole corresponding to the shape of the vibration isolating device is preset on the floating plate 6, and the through hole is reserved as a stepped hole with a large cross section of the upper section and a small section of the lower section. . The shoulder portion B of the stepped hole is provided with a groove 15 corresponding to the hooking position of the hooking stopper. In the jacking installation, the spring isolator 2 and the support stopper 1 are sequentially placed in the reserved through hole, and the spacer 10 is placed at the center hole of the support stopper 1. The position of the lock nut 5 is adjusted until the hitch stop 4 is slightly lower than the shoulder B, and the boom 3 is rotated so that the hitch stop 4 is in the optimal hook position and aligned with the groove 15. Twisting the lock nut 5 causes the hitch stop 4 to be engaged with the shoulder B and located in the recess 15. Then, the lifting block 11 is used to provide a supporting force point, and the spring isolator is pressed by the jacking bracket 13 and the jack 14 to compress the spring isolator 2 until the gasket 10 is completely lower than the supporting block 1 . When the gasket 10 is rotated by about 45°, a gap overlap is formed between the gasket 10 and the support block 1. After the jacking bracket 13 and the jack 14 are removed, the spring isolator 2 will rebound. , the gasket 10 and the support block 1 and the groove 15 of the hook block 4 and the shoulder B are pressed against each other, so that the floating plate 6 is elastically supported on the spring isolator 2 when the spring is carried. When the vibrator is sufficiently large, the floating plate 6 will be detached from the surface of the base 8 to achieve floating, as shown in FIG.

When a spacer 10 is unable to adjust the floating panel 6 to an appropriate height or level, the newly added spacer can be placed at the center through hole of the support stopper 1 according to the foregoing method, and then passed through a pressure tool. The jacking through hole provided in the center of the gasket directly presses the spring isolator until the newly placed gasket is completely lower than the supporting stopper. At this time, the newly placed gasket is rotated by about 45° to make the newly set mat. The sheet also forms a misalignment gap with the support block. After the spring pressure is released, the gasket is pressed against the support block, so that the total thickness of the gasket is adjusted until the floating plate is finally realized. Achieve the appropriate height and level.

In order to prevent the spring isolator 1 from slipping horizontally, an anti-skid pad 7 having a high friction coefficient is disposed between the spring isolator 1 and the support block 1, and the surfacing is used between the spring isolator 1 and the base 8. A plurality of needle-like projections 12 are provided. In order to prevent foreign matter from falling into the through hole of the floating plate, the end cover 9 is provided at the top of the reserved through hole. The end cap 9釆 is embedded so that the upper surface is flush with the surface of the floating plate, which is more beautiful and practical.

Since the hooking stopper 4 is disposed in the recess 15 during operation, the slippage cannot be rotated, so that the hooking between the vibration isolating device and the floating plate is safer and more reliable.

According to the spirit of the present invention, the shape of the through hole supporting the center of the stopper may be a shape of a triangle, a trapezoid, an ellipse, a rectangle or the like in addition to the shape described in the embodiment, as long as the corresponding gasket is changed. The shape can achieve the same effect. Moreover, the structural form of the gasket according to the present invention is not limited to a solid plate. For a case where the thickness of the floating plate is large, the gasket may be provided as a hollow casing and a barrel structure with flanges at both ends. Various forms, as long as the strength is sufficient, can achieve the same effect. In addition, in addition to providing a jacking block between the lock nut, the jacking block can be integrated with the lock nut, even after the lock nut is assembled, and the jacking block is fixed by the threaded structure. The upper end of the boom or directly welded to the upper end of the boom can also achieve good results.

Embodiment 3

As shown in FIG. 9, the difference from the second embodiment is that the boom 3 is provided with a shoulder 31, and the shoulder 31 is matched with the support block 1 to limit the position. The boom 3 uses the thread structure and the hanging gear provided at the lower end thereof. The blocks are connected and the lock block is locked with a locknut. When the boom is assembled with the support block, the boom can be connected to the hitch block from top to bottom through the support stop. In addition, the setting of the jacking block 11 can also be provided in a manner similar to the lock nut 5. Thus, if the size of the thread segment of the upper part of the boom 3 is normalized, the jacking block integrated with the lock nut can be removed and used for the next isolator after completing the top lift of the isolator. The rise of the top is conducive to saving materials and further reducing costs. The spacer 10 is provided in a plurality of pieces, and the thickness thereof may be the same or different depending on actual needs.

In addition, in the vibration isolator described in the first embodiment and the second embodiment, the matching portion of the boom 3 and the support block 1 is convenient for processing and use, and the cross section thereof is set to be circular, and the corresponding support block is disposed on the corresponding support block. Round through hole. The suspension rod of this structure is easy to rotate during use. To overcome this drawback, the cross section of the mating segment A can be set to a square shape, and the shape of the through hole on the corresponding support block is also set to a square shape. The rod is not easy to rotate.

Based on the above principle, the cross-sectional shape of the mating segment A can also be set to a shape such as a rectangle or a regular hexagon, and at the same time, a correspondingly shaped through hole is provided on the support block to cooperate with it, and the function of preventing the boom from rotating can also be realized.

Embodiment 4

In addition to using a rotatable boom, the vibration isolating device of the present invention can also use a swingable boom, as shown in FIG. 10 and FIG. 11, including a support block 1 and a spring isolator 2, and a spring isolator. 1 is located below the support block 1, and the support block 1 is provided with four swinging booms 3, and the lower part of the boom 3 is horizontally disposed with the outwardly extending hooking blocks 4. The support block 1 is provided with a slit at a position corresponding to the boom 3, A locking device for the boom is also provided on the support block. The locking device comprises two fasteners 16. For the convenience of connection, two ear plates 17 are welded and fixed on both sides of the support block gap, and two fasteners 16 are arranged between the ear plate 17 and the boom 3, one of which As the hinge point between the boom and the support block, the other is used to lock the hook position of the boom. In order to adjust the height and level of the vibration isolation member from above, a triangular metal gasket 10 is arranged between the support block and the spring isolator, and a triangular through hole is formed in the center of the corresponding support block, and the gasket 10 can pass through. The holes pass through and can form a misalignment with the support stops.

As shown in Fig. 12, the vibration isolating member 6 is a floating floor of a large building, and the reserved through holes of the floating floor 6 are arranged in a stepped shape. In order to protect the reserved through-hole structure from being damaged, a steel lining 21 is disposed in the reserved through hole, and the lining 21 is pre-cast integrally with the floating floor 6. The correspondingly-lined shoulder 18 of the metal-lined barrel 21 is made of durable stainless steel material, and the corresponding hanging block 4 on the shoulder 18 is also welded with a limiting block 19, and the two limiting blocks 19 are used. The shoulder 18 forms a recess in which the hooking stop 4 is located to prevent slippage. In application, the spring isolator 2 and the support block 1 are sequentially placed in the reserved through holes, and the spacer 10 is placed at the center hole of the support block 1. When inserting, the fastener 16 should be removed first to keep the hinge between the boom 3 and the ear plate 17, and the hooking block 4 is received and aligned with the groove formed by the limiting block 19 and the shoulder 18. Then, the spring isolator 2 is directly pressed by the pressure tool through the jacking through hole provided in the center of the gasket 10 until the newly placed gasket is completely lower than the support stopper and the boom 3 is swinged to the hook position. Block 4 is slightly lower than the shoulder 18, at this time the fastener 16 is attached to keep the boom in a state of being hung, and the gasket is rotated through about 60° to form a misalignment between the gasket and the support stopper. After the spring isolating spring is released, the gasket is pressed against the supporting block, and the supporting block is forced to rise. The hanging block 4 is hooked in the groove formed by the limiting block 19 and the shoulder 18, so that The floating floor is supported on the spring isolator. As a result, the other vibration isolating devices are continuously lifted, and when the spring isolator is loaded enough, the floating floor 6 will be separated from the surface of the foundation 8, as shown in FIG.

In order to prevent the spring isolator 1 from slipping horizontally, an anti-skid pad 7 having a high friction coefficient is disposed between the spring isolator 1 and the support block 1 and between the spring isolator 2 and the base 8. In order to prevent foreign matter from falling into the through hole of the floating plate, a stopper 20 is disposed on the top of the reserved through hole, and the end cover 9 is disposed on the stopper 20.

In addition to the swinging direction of the boom as shown in this example, the same effect can be achieved by swinging the boom in the tangential direction of the contour of the support stop. In particular, the swinging boom is due to The horizontal direction space required for the hooking is small, so that only the shoulder can be partially engaged with the hooking stopper in the lower portion of the reserved through hole of the vibration isolating member.

Since the support block can be taken out at any time, the spring isolator does not have to be taken out from the through hole in the middle of the support block, so the size of the spring isolator can be prevented from being restricted by the through hole on the support block, which is advantageous for further reducing the product. The overall size saves material and thus reduces the cost of the product.

Based on the application principle of the locking device described in this example, in order to ensure the reliability of the hook, a locking device can also be provided between the rotatable or moving boom and the support block. In addition to the fasteners provided between the support block and the boom, the locking device can also be a pin, a wedge, a fastener or a chain, and the same effect can be achieved.

Embodiment 5

As shown in FIG. 13 and FIG. 14, the vibration isolating device of the present invention is different from the first embodiment in that the supporting block 1 is integrated with the upper top plate 2a of the spring isolator 2, and the supporting block 1 is provided with the boom 3 Fit the long hole 30. The boom 3 and the elongated hole 30 cooperate with the section A to be processed into a square shape in cross section. As shown in Fig. 15, when used, the vibration isolating device of this structure does not need horizontal rotation when the hook and the hanging block are hooked, and the required horizontal space is small. Therefore, only the lower part of the floating plate 6 is partially provided. The shoulder B is used to replace the shoulder formed by the stepped hole in the first embodiment. The hooking of the hanging block 4 and the shoulder B is realized by shifting the boom 3 outward along the long hole 30, and the wedge is utilized. Block 32 is locked. This is advantageous in ensuring that the strength of the floating plate 6 is not impaired to the utmost extent, and the cost of the product can be further reduced.

Based on the technical solution of the embodiment, the floating plate 6 is provided with a partial shoulder B disposed at a lower portion of the through hole, and may be replaced by a partial insertion hole on the side wall of the reserved through hole when the floating plate is poured.
