Description

Technical Field

[0001] The utility model relates to the technical field of structural vibration reduction, in particular to a tuned mass damper with a fast-detachable locking assembly. Background Art

[0002] During the transportation and installation of the tuned mass damper, the bumps of the vehicle and handling will cause the tuned mass damper to vibrate. In order to prevent excessive vibration from damaging the spring and damper of the tuned mass damper and affecting the performance of the product, a locking device is generally set after the tuned mass damper is assembled to fix the mass block to the frame to ensure that the tuned mass damper does not vibrate during transportation and installation.

[0003] The existing locking device of the tuned mass damper generally has threaded holes set at the bottom of the lower frame and the mass block, and is connected and fixed in the middle by a square tube, and the upper and lower holes of the square tube are opened for installing screws. Although this locking method can effectively fix the mass block, when the installation is completed and the on-site disassembly is carried out, it is necessary to first remove the upper and lower fixing screws and then remove the square tube, which is time-consuming. Especially for some narrow installation locations, due to insufficient disassembly space, the locking screws are often unable to be removed, which seriously affects the vibration reduction effect of the tuned mass damper. Utility Model Content

[0004] The technical problem to be solved by the utility model is that: the locking screw does not have enough disassembly space, resulting in the inability to disassemble the locking structure, so that the tuned mass damper cannot be used normally.

[0005] To this end, the utility model provides a tuned mass damper with a locking assembly that can be quickly disassembled. There is no need to remove screws, and locking is achieved using a self-locking structure. The disassembly process is simple and quick, and is suitable for situations where space is limited, and will not affect the normal use of the tuned mass damper.

[0007] The locking assembly of the utility model can be quickly disassembled into a tuned mass damper, wherein the first limit piece is connected to the frame by a thread, and the second limit piece is connected to the mass block by a thread. In the process of locking or unlocking the tuned mass damper, there is no need to install or remove screws, and the locking is achieved by utilizing the self-locking structure of the locking assembly itself. The disassembly process is simple and quick, and is suitable for situations where the installation space is small, and will not affect the normal use of the tuned mass damper.

[0008] Furthermore, the locking assembly includes a mounting plate and two locking blocks. The mounting plate is provided with two grooves, and the locking blocks are installed in the grooves.

[0009] Furthermore, the mounting plate includes a first side, a second side and a third side, the first side is parallel to and opposite to the second side, the third side is perpendicular to the first side, the groove runs through the first side and the second side, and the openings of the two grooves are both facing the third side.

[0010] Furthermore, the groove includes a first plane, a second plane and a third arc surface, one end of the third arc surface is connected to the first plane, and the other end of the third arc surface is connected to the second plane, the first plane and the second plane are not parallel, and the angle between the first plane and the second plane is θ1.

[0011] Furthermore, the locking block includes a first waist surface and a second waist surface, and the first waist surface and the second waist surface are not parallel.

[0012] Furthermore, the included angle between the first waist surface and the second waist surface is θ2, θ1=θ2<5.7°.

[0013] Furthermore, the first limiting member includes a first connecting portion and a second connecting portion, one end of the first connecting portion is located in the lower connecting plate, the other end of the first connecting portion is connected to the second connecting portion, and the other end of the first connecting portion is located in the groove below.

[0014] Furthermore, the second limiting member includes a third connecting part and a fourth connecting part, one end of the third connecting part is located in the mass block, the other end of the third connecting part is connected to the fourth connecting part, and the other end of the third connecting part is located in the upper groove.

[0015] Furthermore, one side of the other end of the first connecting part abuts against the third arc surface, the other side of the other end of the first connecting part abuts against the locking block, one side of the other end of the third connecting part abuts against the third arc surface, and the other side of the other end of the third connecting part abuts against the locking block.

[0016] Furthermore, the mounting plate also includes a disassembly portion, and the disassembly portion is located between the two grooves.

[0017] The beneficial effect of the utility model is that the first limiter is limited in the groove by the self-locking effect of the groove located at the top and the locking block, and the second limiter is limited in the groove by the self-locking effect of the groove located at the bottom and the locking block, so that when the tuned mass damper is locked, the mass block and the lower frame are separated by the distance between the two grooves;

[0029] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0030] like Figures 1 to 6 As shown, a tuned mass damper with a quickly disassembled locking assembly includes a frame 1, a mass block 2 and a locking assembly 4, wherein the frame 1 includes a lower connecting plate 11, and a first limit piece 111 is provided on the lower connecting plate 11; the mass block 2 is located in the frame 1, and the mass block 2 is connected to the frame 1, and the mass block 2 is located above the lower connecting plate 11, and a second limit piece 21 is provided on the mass block 2; the lower end of the locking assembly 4 is detachably connected to the first limit piece 111, and the upper end of the locking assembly 4 is detachably connected to the second limit piece 21, and the locking assembly 4 is used to lock the mass block 2 and the frame 1.

[0031] The first limit member 111 and the second limit member 21 are screws, and the first limit member 111 is connected to the frame 1 through threads, and the second limit member 21 is connected to the mass block 2 through threads. In the process of locking or unlocking the tuned mass damper, there is no need to install or remove the screws. The locking is achieved by the self-locking structure of the locking assembly 4 itself. The disassembly process is simple and quick, which is suitable for situations where the installation space is small and will not affect the normal use of the tuned mass damper.

[0032] The frame 1 further includes an upper connecting plate and a connecting column, the upper end of the connecting column is fixedly connected to the upper connecting plate, the lower end of the connecting column is fixedly connected to the lower connecting plate 11, the connecting column penetrates the mass block 2, and the tuned mass damper further includes an elastic member, the upper end of the elastic member is connected to the mass block 2, and the lower end of the elastic member is connected to the lower connecting plate 11. If the locking assembly 4 of the tuned mass damper is removed, the mass block 2 can move back and forth between the upper connecting plate and the lower connecting plate 11 through the connecting column and generate a vibration reduction effect through the elastic member.

[0033] The locking assembly 4 includes a mounting plate 41 and two locking blocks 43. The mounting plate 41 is provided with two grooves 42, and the locking blocks 43 are installed in the grooves 42. The first stopper 111 is limited in the groove 42 by the self-locking action of the groove 42 located at the top and the locking blocks 43, and the second stopper 21 is limited in the groove 42 by the self-locking action of the groove 42 located at the bottom and the locking blocks 43, so that when the tuned mass damper is locked, the mass block 2 and the lower frame 11 are separated by the distance between the two grooves 42.

[0034] The mounting plate 41 includes a first side surface 411, a second side surface 412 and a third side surface 413. The first side surface 411 is parallel to and opposite to the second side surface 412, and the third side surface 413 is perpendicular to the first side surface 411. The groove 42 passes through the first side surface 411 and the second side surface 412, and the openings of the two grooves 42 are both toward the third side surface 413. When the mass of the mass block 2 is large, the thickness of the mounting plate 41 can be increased to improve the connection strength and stability.

[0035] By arranging the opening of the groove 42 to face the side, it is convenient for the first limiting member 111 and the second limiting member 21 to enter the groove 42 from the side, ensuring that the tuned mass damper can be locked or unlocked conveniently even when the installation space is small.

[0036] The groove 42 includes a first plane 421, a second plane 422 and a third curved surface 423, one end of the third curved surface 423 is connected to the first plane 421, and the other end of the third curved surface 423 is connected to the second plane 422, the first plane 421 and the second plane 422 are not parallel, and the angle between the first plane 421 and the second plane 422 is θ1. The locking block 43 includes a first waist surface 431 and a second waist surface 432, the first waist surface 431 and the second waist surface 432 are not parallel. The angle between the first waist surface 431 and the second waist surface 432 is θ2, θ1=θ2<5.7°.

[0037] The static friction coefficient of steel is generally 0.1, so its self-locking angle is arctan0.1≈5.7°. When the angle is smaller than this, the wedge block cannot overcome the static friction and disengage. Preferably, in this embodiment, θ1=θ2=3°

[0038] The first limiting member 111 includes a first connecting portion 1111 and a second connecting portion 1112 . One end of the first connecting portion 1111 is located in the connecting plate 11 , and the other end of the first connecting portion 1111 is connected to the second connecting portion 1112 . The other end of the first connecting portion 1111 is located in the upper groove 42 .

[0039] The second limiting member 21 includes a third connection portion 211 and a fourth connection portion 212 . One end of the third connection portion 211 is located in the connection plate 11 , and the other end of the third connection portion 211 is connected to the fourth connection portion 212 . The other end of the third connection portion 211 is located in the groove 42 below.

[0040] One side of the other end of the first connection part 1111 abuts against the third arc surface 423, the other side of the other end of the first connection part 1111 abuts against the locking block 43, one side of the other end of the third connection part 211 abuts against the third arc surface 423, and the other side of the other end of the third connection part 211 abuts against the locking block 43.

[0041] When the tuned mass damper is locked, the second connection portion 1112 presses the mounting plate 41 onto the lower connection plate 11 through the first side surface 411 , and the fourth connection portion 212 presses the mounting plate 41 onto the mass block 2 through the first side surface 411 .

[0042] The mounting plate 41 further includes a disassembly portion 44, which is located between the two grooves 42. When the tuned mass damper is unlocked, the disassembly portion 44 is knocked from the third side surface 413, so that the lower end of the mounting plate 41 is disengaged from the first stopper 111, and the upper end of the mounting plate 41 is disengaged from the second stopper 21, while the two locking blocks 43 are held by the first connection portion 1111 and the third connection portion 211 and will not move with the mounting plate 41, thereby separating the locking blocks 43 from the mounting plate 41 and completing the unlocking.

[0043] Working principle: The locking of the tuned mass damper is achieved by utilizing the self-locking condition of the inclined surface. The angle between the first waist surface 431 and the second waist surface 432 of the locking block 43 is θ2=3°, and the angle between the first plane 421 and the second plane 422 of the groove 42 is θ1=3°. The self-locking condition of the inclined surface is met. Self-locking can be achieved by installing the locking block 43 into the groove 42. The upper groove 42 and the locking block 43 limit the displacement of the second limit member 21 through self-locking, and the lower groove 42 and the locking block 43 limit the displacement of the first limit member 111 through self-locking, thereby keeping the relative position between the mass block 2 and the lower frame 11 unchanged.

[0044] Based on the above ideal embodiments of the utility model, the relevant staff can make various changes and modifications without departing from the technical concept of the utility model through the above description. The technical scope of the utility model is not limited to the content of the specification, and its technical scope must be determined according to the scope of the claims.
