Description
本發明係關於一種用於衰減振動能之阻尼裝置及阻尼力切換結構。The present invention relates to a damping device and a damping force switching structure for damping vibration energy.
過去習知有利用黏性流體之抗剪力來衰減振動能的阻尼裝置(例如,參照日本特開第2016-180433號公報)。In the past, there has been known a damping device that uses the shearing force of a viscous fluid to attenuate vibration energy (for example, refer to Japanese Laid-Open Patent Publication No. 2016-180433).
揭示於日本特開第2016-180433號公報之阻尼裝置包括:固定於一側結構物之螺桿軸;與固定於另一側結構物之圓筒。在該圓筒內部收容有筒狀之旋轉體,該旋轉體中固定有與螺桿軸螺合,而將沿著螺桿軸之軸方向的運動轉換成旋轉運動的螺母構件。此外,在形成於旋轉體之外周面與圓筒的內周面之間的密閉空間充填有黏性流體。因為該黏性流體之抗剪力作用於旋轉運動之旋轉體,所以可衰減在一側結構物與另一側結構物之間傳導的振動能。The damper device disclosed in Japanese Laid-Open Patent Publication No. 2016-180433 includes a screw shaft fixed to one side structure and a cylinder fixed to the other side structure. A cylindrical rotating body is housed inside the cylinder, and a nut member that is screwed to the screw shaft and converts the movement in the axial direction of the screw shaft into a rotational motion is fixed to the rotating body. Further, a viscous fluid is filled in a sealed space formed between the outer peripheral surface of the rotating body and the inner peripheral surface of the cylinder. Since the shearing force of the viscous fluid acts on the rotating body of the rotational motion, the vibrational energy conducted between the one side structure and the other side structure can be attenuated.
(發明所欲解決之問題)(The problem that the invention wants to solve)
近年來建築結構物之避震結構,習知有設於建築結構物與其建築地基之間,使該建築結構物與建築地基之搖動絕緣者。採用此種避震結構時,即使振動能因地震等而傳播至建築結構物,建築結構物與建築地基之振動週期無關,而可以其獨自之振動週期搖動。不過,上述避震結構時,由於是將建築結構物與建築地基之搖動絕緣,因此即使地震停止後,建築結構物之搖動仍持續。為了使該建築結構物持續的搖動儘早平息,一個例子是使用上述之阻尼裝置作為避震結構的元件。In recent years, the suspension structure of building structures has been known to be located between the building structure and its building foundation, so that the building structure and the building foundation are shaken and insulated. When such a suspension structure is used, even if the vibration energy propagates to the building structure due to an earthquake or the like, the building structure is independent of the vibration period of the building foundation, and can be shaken by its own vibration cycle. However, in the above-mentioned suspension structure, since the building structure is insulated from the shaking of the building foundation, the shaking of the building structure continues even after the earthquake stops. In order to calm the shaking of the building structure as early as possible, an example is to use the above-described damping device as an element of the suspension structure.
阻尼裝置係吸收振動能,反之,也發揮使建築結構物追隨建築地基的功能。因而,假設發生大地震,而提高設定阻尼裝置中吸收振動能之能力時,建築地基之搖動容易傳播至建築結構物,而難以發揮使建築結構物與建築地基之搖動絕緣的避震結構原本之功能。考慮到這一點,為了有效利用避震結構的功能,就無法將阻尼裝置之吸收能力設定過高,而不得不對應於通常想得到之規模的地震來決定阻尼裝置的吸收能力。但是,在如此設定阻尼裝置之吸收能力的狀態下,發生大地震時,又無法藉由阻尼裝置充分吸收地震的振動能。結果建築結構物相對建築地基之搖動幅度增大。此外,因為阻尼裝置無法充分吸收振動能,所以無法使建築結構物之搖動儘早平息。The damper device absorbs vibrational energy and, conversely, functions as a building structure to follow the building foundation. Therefore, assuming that a large earthquake occurs and the ability to absorb vibration energy in the damping device is increased, the shaking of the building foundation easily spreads to the building structure, and it is difficult to exert a shock-absorbing structure that insulates the building structure from the shaking of the building foundation. Features. In view of this, in order to effectively utilize the function of the suspension structure, the absorption capacity of the damping device cannot be set too high, and the absorption capacity of the damping device has to be determined corresponding to the earthquake of the size that is usually desired. However, in the state where the absorbing ability of the damper device is set as described above, when a large earthquake occurs, the vibration energy of the earthquake cannot be sufficiently absorbed by the damper device. As a result, the amplitude of the building structure relative to the building foundation increases. In addition, since the damper device cannot sufficiently absorb the vibration energy, the shaking of the building structure cannot be quelled as early as possible.
另外,假設發生大地震而增加設置阻尼裝置的數量時,則阻尼裝置對小規模地震的效用過高,而有無法發揮避震結構之避震功能的問題。Further, assuming that a large earthquake occurs and the number of the damper devices is increased, the damper device is too effective for a small-scale earthquake, and there is a problem that the shock absorbing function of the suspension structure cannot be exhibited.
本發明之課題為考慮上述情形,提供一種依地震力大小產生阻尼力(damping force)之阻尼裝置(damping device)及阻尼力切換結構。 (解決問題之手段)An object of the present invention is to provide a damping device and a damping force switching structure that generate a damping force depending on the magnitude of the earthquake force in consideration of the above situation.

The screw shaft 32 constitutes a reciprocating motion in the axial direction. Further, as shown in FIGS. 2 and 3, an insertion hole 33 into which the end portion 26A of the brake pin 26 can be inserted is formed at the other end portion 32A of the screw shaft 32. In addition, the axial direction of the screw shaft is indicated by an arrow Y in the figure.
如第1圖所示,螺母構件34固定於旋轉體30。該螺母構件34與螺桿軸32螺合,可將沿著螺桿軸32之軸方向的往返運動轉換成旋轉體30的旋轉運動。As shown in FIG. 1, the nut member 34 is fixed to the rotating body 30. The nut member 34 is screwed to the screw shaft 32, and the reciprocating motion in the axial direction of the screw shaft 32 can be converted into the rotational motion of the rotating body 30.
如第2圖及第3圖所示,保持單元24使螺桿軸32之另一端部32A可旋轉地被保持。該保持單元24包括:收容螺桿軸32之另一端部32A的機殼40;及安裝於機殼40內,使螺桿軸32之另一端部32A可旋轉地被保持的軸承42。如第2圖所示,機殼40為圓筒狀,且一端以連結部41閉塞。在該機殼40之周壁部40A上設有收容制動銷26的貫穿孔43。此外,機殼40之連結部41係用於將機殼40對其他結構物C2連結的部位(參照第6圖)。As shown in FIGS. 2 and 3, the holding unit 24 rotatably holds the other end portion 32A of the screw shaft 32. The holding unit 24 includes a casing 40 that houses the other end portion 32A of the screw shaft 32, and a bearing 42 that is attached to the casing 40 to rotatably hold the other end portion 32A of the screw shaft 32. As shown in FIG. 2, the casing 40 has a cylindrical shape, and one end thereof is closed by a joint portion 41. A through hole 43 for accommodating the brake pin 26 is provided in the peripheral wall portion 40A of the casing 40. Further, the connecting portion 41 of the casing 40 is a portion for connecting the casing 40 to the other structure C2 (see Fig. 6).
如第2圖至第5圖所示,制動銷26係構成收容於機殼40之貫穿孔43內,並在允許螺桿軸32旋轉之允許旋轉位置(制動銷26在第2圖及第3圖中的位置)與停止螺桿軸32旋轉之停止旋轉位置(制動銷26在第4圖及第5圖的位置)之間移動。具體而言,當制動銷26在停止旋轉位置時,制動銷26******孔33,藉由制動銷26與***孔33嚙合而停止螺桿軸32之旋轉。另外,當制動銷26在允許旋轉位置時,因為制動銷26從***孔33離開,所以允許螺桿軸32旋轉。As shown in FIGS. 2 to 5, the brake pin 26 is formed in the through hole 43 of the casing 40 and is allowed to rotate in the rotation of the screw shaft 32 (the brake pin 26 is shown in FIGS. 2 and 3). The middle position is moved between the stop rotation position at which the rotation of the screw shaft 32 is stopped (the brake pin 26 is at the positions of FIGS. 4 and 5). Specifically, when the brake pin 26 is in the stop rotation position, the brake pin 26 is inserted into the insertion hole 33, and the rotation of the screw shaft 32 is stopped by the engagement of the brake pin 26 with the insertion hole 33. In addition, when the brake pin 26 is in the allowable rotational position, since the brake pin 26 is separated from the insertion hole 33, the screw shaft 32 is allowed to rotate.
此外,在制動銷26之側面26B設有***後述之保持銷48的***孔27。Further, an insertion hole 27 into which a holding pin 48 to be described later is inserted is provided on the side surface 26B of the brake pin 26.

Specifically, the holding pin 48 is housed in the through hole 62 that penetrates the peripheral wall portion 40A in the axial direction of the screw shaft 32 from the hole wall surface of the through hole 43 of the casing 40. A coil spring 64 that biases the holding pin 48 toward the through hole 43 is housed in the through hole 62. The holding pin 48 is biased toward the brake pin 26 by the biasing force of the coil spring 64, and the front end portion 48A is inserted into the insertion hole 27 of the brake pin 26.
如第2圖所示,紐狀構件50連接保持銷48與軸構件52。具體而言,係將紐狀構件50之一端部連接於保持銷48的基端部48B,並將紐狀構件50之另一端部連接於軸構件52的一端部52A側之外周。此外,紐狀構件50在***銷60位於引導溝58之第一溝部58A內時,係在賦予指定張力之狀態下連接保持銷48與軸構件52。As shown in FIG. 2, the button member 50 connects the holding pin 48 and the shaft member 52. Specifically, one end portion of the button member 50 is connected to the base end portion 48B of the holding pin 48, and the other end portion of the link member 50 is connected to the outer circumference of the one end portion 52A side of the shaft member 52. Further, when the insertion pin 60 is positioned in the first groove portion 58A of the guide groove 58, the button member 50 is connected to the holding pin 48 and the shaft member 52 in a state where the specified tension is applied.
如第1圖所示,軸構件52係與螺桿軸32一起直線運動的構件,且與螺桿軸32平行地配置。As shown in FIG. 1, the shaft member 52 is a member that linearly moves together with the screw shaft 32, and is disposed in parallel with the screw shaft 32.
如第2圖及第3圖所示,第一支撐部54設於保持單元24之機殼40的外周面。該第一支撐部54使軸構件52之一端部52A可旋轉地被支撐。As shown in FIGS. 2 and 3, the first support portion 54 is provided on the outer circumferential surface of the casing 40 of the holding unit 24. The first support portion 54 rotatably supports one end portion 52A of the shaft member 52.
如第1圖及第10圖所示,第二支撐部56設於圓筒28之外周面。該第二支撐部56使軸構件52之中間部52C可旋轉地被支撐。另外,此處所謂軸構件52之中間部52C,是指軸構件52之一端部52A與另一端部52B之間的部分(參照第6圖)。As shown in FIGS. 1 and 10, the second support portion 56 is provided on the outer circumferential surface of the cylinder 28. The second support portion 56 rotatably supports the intermediate portion 52C of the shaft member 52. Here, the intermediate portion 52C of the shaft member 52 herein refers to a portion between the one end portion 52A of the shaft member 52 and the other end portion 52B (see Fig. 6).
如第10圖所示,引導溝58設於軸構件52,並從一端部52A側向另一端部52B側延伸。具體而言,引導溝58包括:沿著軸構件52之軸方向延伸的第一溝部58A;及從第一溝部58A之兩端部朝向軸方向兩外側,而相對於軸方向斜向延伸之一對第二溝部58B。另外,兩側之第二溝部58B係從第一溝部58A沿著軸構件52之外周面在相同方向延伸。此外,引導溝58具有從第二溝部58B之端部沿著軸構件52的軸方向而延伸之第三溝部58C(參照第8圖及第9圖)。As shown in Fig. 10, the guide groove 58 is provided in the shaft member 52, and extends from the one end portion 52A side toward the other end portion 52B side. Specifically, the guide groove 58 includes: a first groove portion 58A extending in the axial direction of the shaft member 52; and one of the outer sides from the both end portions of the first groove portion 58A toward the axial direction and obliquely extending with respect to the axial direction The second groove portion 58B. Further, the second groove portions 58B on both sides extend from the first groove portion 58A in the same direction along the outer circumferential surface of the shaft member 52. Further, the guide groove 58 has a third groove portion 58C extending from the end portion of the second groove portion 58B in the axial direction of the shaft member 52 (see FIGS. 8 and 9).
如第11圖所示,***銷60設於第二支撐部56,並***引導溝58。該***銷60藉由螺桿軸32之直線運動而從第一溝部58A向第二溝部58B移動時,可使藉由第一支撐部54與第二支撐部56而可旋轉地被支撐之軸構件52旋轉(參照第8圖及第9圖)。As shown in Fig. 11, the insertion pin 60 is provided in the second support portion 56, and is inserted into the guide groove 58. When the insertion pin 60 moves from the first groove portion 58A to the second groove portion 58B by the linear movement of the screw shaft 32, the shaft member rotatably supported by the first support portion 54 and the second support portion 56 can be supported. 52 rotation (refer to Figure 8 and Figure 9).
其次,說明本實施形態之阻尼裝置22的阻尼力切換機制。Next, the damping force switching mechanism of the damper device 22 of the present embodiment will be described.
首先,使圓筒28與螺桿軸32相對移動。具體而言,係使螺桿軸32對圓筒28直線運動(往返運動)。此時如第2圖及第3圖所示,***銷60在引導溝58之第一溝部58A內,而移動機構44未發揮功能時,制動銷26在允許旋轉位置。當制動銷26在允許旋轉位置時,由於螺桿軸32在旋轉的同時直線運動,因此螺桿軸32在軸方向之往復運動不致轉換成螺母構件34的旋轉運動,此外,旋轉體30與螺母構件34之旋轉也受到黏性流體之抗剪力的阻礙。此時阻尼裝置22不發生阻尼力。First, the cylinder 28 is moved relative to the screw shaft 32. Specifically, the screw shaft 32 is linearly moved (reciprocating motion) to the cylinder 28. At this time, as shown in FIGS. 2 and 3, the insertion pin 60 is in the first groove portion 58A of the guide groove 58, and when the movement mechanism 44 does not function, the brake pin 26 is in the allowable rotation position. When the brake pin 26 is in the allowable rotational position, since the screw shaft 32 linearly moves while rotating, the reciprocating motion of the screw shaft 32 in the axial direction is not converted into the rotational motion of the nut member 34, and further, the rotating body 30 and the nut member 34 The rotation is also hindered by the shear resistance of the viscous fluid. At this time, the damping device 22 does not generate a damping force.
此外,當螺桿軸32直線運動時,軸構件52也與螺桿軸32一起直線運動。藉由軸構件52之直線運動,而***銷60從引導溝58之第一溝部58A向第二溝部58B移動時,可旋轉地被支撐之軸構件52相對固定的***銷60旋轉(參照第8圖及第9圖)。Further, when the screw shaft 32 moves linearly, the shaft member 52 also moves linearly with the screw shaft 32. When the insertion pin 60 moves from the first groove portion 58A of the guide groove 58 to the second groove portion 58B by the linear movement of the shaft member 52, the rotatably supported shaft member 52 rotates relative to the fixed insertion pin 60 (refer to the eighth Figure and Figure 9).
當軸構件52旋轉時,如第4圖所示,捲繞於軸構件52外周面之紐狀構件50拉伸,保持銷48克服線圈彈簧46之施加力而移動(參照第4圖及第5圖)。藉此,保持銷48之前端部48A從制動銷26的***孔27抽出,而解除制動銷26之保持狀態。When the shaft member 52 rotates, as shown in Fig. 4, the link member 50 wound around the outer peripheral surface of the shaft member 52 is stretched, and the holding pin 48 moves against the biasing force of the coil spring 46 (refer to Figs. 4 and 5). Figure). Thereby, the front end portion 48A of the holding pin 48 is withdrawn from the insertion hole 27 of the brake pin 26, and the holding state of the brake pin 26 is released.
解除保持狀態時,制動銷26藉由線圈彈簧46之施加力而從允許旋轉位置向停止旋轉位置移動,而***設於螺桿軸32之另一端部32A的***孔33,制動銷26與***孔33嚙合(參照第4圖及第5圖)。藉此,螺桿軸32之另一端部32A固定於保持單元24,螺桿軸32不旋轉地直線運動。因為螺桿軸32不旋轉地直線運動,所以螺母構件34與旋轉體30一起旋轉。藉由旋轉體30之旋轉,在密閉空間內之黏性流體L的抗剪力作用於旋轉體30,衰減螺桿軸32往返運動時的能。亦即,阻尼裝置22發生阻尼力。When the hold state is released, the brake pin 26 is moved from the allowable rotation position to the stop rotation position by the biasing force of the coil spring 46, and is inserted into the insertion hole 33 provided at the other end portion 32A of the screw shaft 32, the brake pin 26 and the insertion hole. 33 meshing (refer to Figures 4 and 5). Thereby, the other end portion 32A of the screw shaft 32 is fixed to the holding unit 24, and the screw shaft 32 linearly moves without rotation. Since the screw shaft 32 moves linearly without rotation, the nut member 34 rotates together with the rotating body 30. By the rotation of the rotating body 30, the shearing force of the viscous fluid L in the sealed space acts on the rotating body 30, attenuating the energy when the screw shaft 32 reciprocates. That is, the damping device 22 generates a damping force.
其次,使用第7A圖及第7B圖說明本實施形態之阻尼裝置22從開始激振至結束激振的阻尼特性。另外,以下之(1)~(7)對應於第7A圖及第7B圖中的(1)~(7)。Next, the damping characteristics of the damper device 22 of the present embodiment from the start of the excitation to the end of the excitation will be described using Figs. 7A and 7B. Further, the following (1) to (7) correspond to (1) to (7) in FIGS. 7A and 7B.
(1)使圓筒28與螺桿軸32相對移動,對阻尼裝置22賦予振動能的狀態。亦即,開始對阻尼裝置22激振。(1) The cylinder 28 is moved relative to the screw shaft 32 to impart vibration energy to the damper device 22. That is, the damper device 22 is initially excited.
(2)軸構件52與螺桿軸32一起直線運動,但是***銷60尚未到達引導溝58之第二溝部58B的狀態。在該狀態下不發生阻尼力。(2) The shaft member 52 linearly moves together with the screw shaft 32, but the insertion pin 60 has not yet reached the state of the second groove portion 58B of the guide groove 58. No damping force occurs in this state.
(3)因為軸構件52在直線運動中的位移超過設定值,亦即***銷60已到達引導溝58的第二溝部58B,所以依據前述之切換機制而發生阻尼力的狀態。(3) Since the displacement of the shaft member 52 in the linear motion exceeds the set value, that is, the insertion pin 60 has reached the second groove portion 58B of the guide groove 58, the state of the damping force occurs in accordance with the aforementioned switching mechanism.
(4)、(5)維持在軸構件52在直線運動中之位移超過設定值的狀態。亦即,***銷60從一側第二溝部58B通過第一溝部58A向另一側的第二溝部58B移動,然後返回一側第二溝部58B的狀態。(4) and (5) maintain the state in which the displacement of the shaft member 52 in the linear motion exceeds the set value. That is, the insertion pin 60 moves from the one side second groove portion 58B to the other second groove portion 58B through the first groove portion 58A, and then returns to the one side second groove portion 58B.
(6)軸構件52在直線運動中之位移低於設定值,亦即,***銷60未達第二溝部58B之狀態。在該狀態下仍維持發生阻尼力。(6) The displacement of the shaft member 52 in the linear motion is lower than the set value, that is, the state in which the insertion pin 60 does not reach the second groove portion 58B. The damping force is still maintained in this state.
(7)在阻尼裝置22可發生阻尼力之狀態(制動銷26******孔27的狀態)下,結束對阻尼裝置22激振。(7) When the damper device 22 can generate a damping force (a state in which the brake pin 26 is inserted into the insertion hole 27), the damper device 22 is excited.
另外,上述(1)~(7)係阻尼裝置22發生阻尼力之第1個週期對振動的阻尼特性,且係對第1個週期以後(例如第2個週期)之振動,從最初阻尼裝置22發生阻尼力之狀態。Further, in the above (1) to (7), the damper device 22 generates a damping characteristic of the first period of the damping force against the vibration, and is a vibration after the first period (for example, the second period), from the initial damper device. 22 The state of the damping force occurs.
其次,說明本實施形態之作用效果。 阻尼裝置22係在因地震時等而彼此相對移動的一側結構物C1上連結圓筒28之連結部36,且另一側結構物C2上連結保持單元24之連結部41時,於地震時而制動銷26在允許旋轉位置時,即使一側結構物C1與另一側結構物C2相對移動,阻尼裝置22仍不發生阻尼力。因而,阻尼裝置22成為阻力,例如可抑制使避震結構之避震性能惡化。Next, the effects of the embodiment will be described. The damper device 22 connects the connection portion 36 of the cylinder 28 to the one side structure C1 that moves relative to each other during an earthquake or the like, and the connection portion 41 of the holding unit 24 is connected to the other side structure C2. When the brake pin 26 is in the allowable rotational position, even if the one side structure C1 moves relative to the other side structure C2, the damping device 22 does not generate a damping force. Therefore, the damper device 22 becomes a resistance, and for example, it is possible to suppress deterioration of the suspension performance of the suspension structure.
此外,當制動銷26在停止旋轉位置時,螺桿軸32之直線運動轉換成收容於圓筒28之旋轉體30的旋轉運動,阻尼裝置22藉由作用於旋轉體30之黏性流體L的抗剪力而發生阻尼力。如此,藉由操作制動銷26可使阻尼裝置22依地震力發生阻尼力。例如,可採用地震力大之大地震時,使阻尼力發生,地震力小之小規模地震及中規模地震時,阻尼裝置22不發生阻尼力,避免阻礙避震結構之功能的避震設計。Further, when the brake pin 26 is in the stop rotation position, the linear motion of the screw shaft 32 is converted into the rotational motion of the rotary body 30 accommodated in the cylinder 28, and the damping device 22 is resistant by the viscous fluid L acting on the rotary body 30. Damping force occurs due to shear. Thus, by operating the brake pin 26, the damper device 22 can generate a damping force according to the seismic force. For example, when a large earthquake with a large earthquake force is used, the damping force is generated, and when the earthquake force is small and the medium-scale earthquake is small, the damping device 22 does not generate a damping force, and the suspension design that hinders the function of the suspension structure is avoided.
再者,因為阻尼裝置22在小規模地震及中規模地震中不會阻礙避震裝置之功能,所以增加阻尼裝置22之設置數量即可因應大地震。Furthermore, since the damper device 22 does not hinder the function of the suspension device in small-scale earthquakes and medium-scale earthquakes, the number of dampers 22 can be increased in response to a large earthquake.
此外,阻尼裝置22於制動銷26在停止旋轉位置時,制動銷26之前端部26A***螺桿軸32的***孔33,停止螺桿軸32之旋轉。亦即,可以將制動銷26之前端部26A******孔33的簡單結構來停止螺桿軸32的旋轉。Further, when the brake pin 26 is in the stop rotation position, the front end portion 26A of the brake pin 26 is inserted into the insertion hole 33 of the screw shaft 32 to stop the rotation of the screw shaft 32. That is, the simple structure of the front end portion 26A of the brake pin 26 can be inserted into the insertion hole 33 to stop the rotation of the screw shaft 32.
再者,阻尼裝置22係在螺桿軸32於直線運動中之位移超過設定值時,移動機構44發揮功能使制動銷26向停止旋轉位置移動。藉此,可使阻尼裝置22發生阻尼力。此時,藉由設定使阻尼裝置22發生阻尼力之螺桿軸32在直線運動中的位移之設定值,亦即軸構件52在引導溝58之第一溝部58A的長度L1(參照第10圖),可在螺桿軸32與圓筒28希望之相對位置發生阻尼力。藉此,可調節複數個阻尼裝置22各個在螺桿軸32之直線運動中的位移設定值,而在各個時間使阻尼裝置22發生阻尼力。Further, when the displacement of the screw shaft 32 during the linear motion exceeds the set value, the damper device 22 functions to move the brake pin 26 to the stop rotation position. Thereby, the damping device 22 can generate a damping force. At this time, the set value of the displacement of the screw shaft 32 that causes the damping force of the damper device 22 to move in the linear motion, that is, the length L1 of the first groove portion 58A of the guide groove 58 of the shaft member 52 (see FIG. 10) is set. A damping force can be generated at a desired position of the screw shaft 32 and the cylinder 28. Thereby, the displacement setting values of the plurality of damping devices 22 in the linear motion of the screw shaft 32 can be adjusted, and the damping device 22 is caused to generate a damping force at each time.
此外,阻尼裝置22於螺桿軸32在直線運動中之位移超過設定值時,紐狀構件50解除制動銷26藉由保持銷48的保持。藉此,制動銷26藉由線圈彈簧46之施加力而從允許旋轉位置向停止旋轉位置移動,螺桿軸32之直線運動轉換成旋轉體30的旋轉運動。此時,因為阻尼裝置22係以線圈彈簧46之施加力使制動銷26移動,所以,例如與使用電動構件而使制動銷26移動的結構比較,其結構簡單且經濟性優異。Further, when the displacement of the damper device 22 in the linear motion exceeds the set value, the button member 50 releases the brake pin 26 by the holding of the retaining pin 48. Thereby, the brake pin 26 is moved from the allowable rotation position to the stop rotation position by the biasing force of the coil spring 46, and the linear motion of the screw shaft 32 is converted into the rotational motion of the rotary body 30. At this time, since the damper device 22 moves the brake pin 26 by the urging force of the coil spring 46, for example, the structure is simple and economical, as compared with a configuration in which the brake pin 26 is moved using the electric component.
阻尼裝置22係在地震時使軸構件52與螺桿軸32一起直線運動,***銷60藉由軸構件52之直線運動而從第一溝部58A向第二溝部58B移動時,軸構件52相對***銷60旋轉。紐狀構件50隨著該軸構件52之旋轉,解除制動銷26藉由保持銷48之保持。因而,阻尼裝置22因為係以不使用電力之機構解除制動銷26的保持,所以,例如與使用電力之機構比較,其經濟性優異。此外,因為係不使用電力之機構,所以即使在不供電狀態下,當螺桿軸32在直線運動中之位移超過設定值情況下,可使制動銷26從允許旋轉位置確實向停止旋轉位置移動。The damper device 22 linearly moves the shaft member 52 together with the screw shaft 32 during an earthquake, and when the insertion pin 60 moves from the first groove portion 58A to the second groove portion 58B by linear movement of the shaft member 52, the shaft member 52 is relatively inserted into the pin. 60 rotations. With the rotation of the shaft member 52, the button member 50 is released by the retaining pin 48. Therefore, since the damper device 22 releases the brake pin 26 by the mechanism that does not use electric power, it is excellent in economy, for example, compared with a mechanism using electric power. Further, since the mechanism for not using electric power is used, even in the non-power supply state, when the displacement of the screw shaft 32 in the linear motion exceeds the set value, the brake pin 26 can be surely moved from the allowable rotation position to the stop rotation position.
另外,本實施形態係藉由連結於一側結構物C1之圓筒28、旋轉體30、螺桿軸32、螺母構件34、連結於另一側結構物C2之保持單元24、及制動銷26而構成阻尼力切換結構S。Further, in the present embodiment, the cylinder 28, the rotating body 30, the screw shaft 32, the nut member 34, the holding unit 24 coupled to the other side structure C2, and the brake pin 26 are coupled to the one side structure C1. A damping force switching structure S is formed.
前述之實施形態係藉由軸構件52之旋轉,經由紐狀構件50拉伸保持銷48,而從***孔27抽出的構成,不過本發明不限定於該構成。亦可取代紐狀構件50及線圈彈簧64,例如為使用牽引(Pull)型之電磁致動器,使保持銷48從***孔27抽出的構成。此時,藉由形成以光學感測器等檢測螺桿軸32在直線運動中之位移,並依檢測資料使上述電磁致動器工作的構成,可減少紐狀構件50、軸構件52及線圈彈簧64等零件數量。此外,亦可獲得與前述實施形態同樣之作用效果。In the above-described embodiment, the shaft member 52 is rotated, and the holding pin 48 is stretched by the button member 50 to be taken out from the insertion hole 27. However, the present invention is not limited to this configuration. Instead of the button member 50 and the coil spring 64, for example, a pull type electromagnetic actuator is used to take out the holding pin 48 from the insertion hole 27. At this time, by forming a configuration in which the displacement of the screw shaft 32 in the linear motion is detected by an optical sensor or the like, and the electromagnetic actuator is operated in accordance with the detection data, the button member 50, the shaft member 52, and the coil spring can be reduced. 64 and other parts. Further, the same operational effects as those of the above embodiment can be obtained.
此外,前述實施形態係使制動銷26藉由線圈彈簧46之施加力而從允許旋轉位置向停止旋轉位置移動的構成,不過,本發明不限定於該構成。亦可取代線圈彈簧46,例如為使用推動(Push)型之電磁致動器,以活動鐵心之按壓力使制動銷26從允許旋轉位置向停止旋轉位置移動的構成。此時,藉由形成以光學感測器等檢測螺桿軸32在直線運動中之位移,並依檢測資料使上述電磁致動器工作的構成,可減少線圈彈簧46、保持銷48、紐狀構件50、軸構件52及線圈彈簧64等之零件數量。此外,亦可獲得與前述實施形態同樣之作用效果。Further, in the above-described embodiment, the brake pin 26 is configured to move from the allowable rotation position to the stop rotation position by the biasing force of the coil spring 46. However, the present invention is not limited to this configuration. Instead of the coil spring 46, for example, a push type electromagnetic actuator is used to move the brake pin 26 from the allowable rotation position to the stop rotation position by the pressing force of the movable iron core. At this time, by forming a configuration in which the displacement of the screw shaft 32 in the linear motion is detected by an optical sensor or the like, and the electromagnetic actuator is operated in accordance with the detection data, the coil spring 46, the holding pin 48, and the button member can be reduced. 50. Number of parts of the shaft member 52 and the coil spring 64. Further, the same operational effects as those of the above embodiment can be obtained.
再者,前述實施形態係制動銷26從允許旋轉位置向停止旋轉位置移動並******孔33後,維持在藉由線圈彈簧46之施加力而制動銷26******孔33的狀態,不過,本發明不限定於該構成。例如,亦可使保持單元24具備在地震結束後將制動銷26返回允許旋轉位置的功能。例如亦可使用牽引型之電磁致動器,使制動銷26抵抗線圈彈簧46之施加力而從停止旋轉位置向允許旋轉位置移動。此種情況下,於地震結束後可使制動銷26自動返回允許旋轉位置。Further, in the above-described embodiment, the brake pin 26 is moved from the allowable rotation position to the stop rotation position and inserted into the insertion hole 33, and the brake pin 26 is inserted into the insertion hole 33 by the biasing force of the coil spring 46. The invention is not limited to this configuration. For example, the holding unit 24 may be provided with a function of returning the brake pin 26 to the allowable rotational position after the end of the earthquake. For example, a traction type electromagnetic actuator may be used to move the brake pin 26 from the stop rotation position to the allowable rotation position against the biasing force of the coil spring 46. In this case, the brake pin 26 can be automatically returned to the allowable rotational position after the end of the earthquake.
前述實施形態係使圓筒28內之旋轉體30旋轉的構成,不過本發明不限定於該構成。例如亦可為將旋轉體30配置於圓筒28的外側,並在旋轉體30與圓筒28間之密閉空間充填黏性流體的構成。該情況下,除了黏性流體的剪力之外,還可藉由旋轉體30之慣性力來衰減振動能。The above embodiment is a configuration in which the rotating body 30 in the cylinder 28 is rotated. However, the present invention is not limited to this configuration. For example, the rotating body 30 may be disposed outside the cylinder 28, and a viscous fluid may be filled in a sealed space between the rotating body 30 and the cylinder 28. In this case, in addition to the shearing force of the viscous fluid, the vibration energy can be attenuated by the inertial force of the rotating body 30.
以上,舉出實施形態說明本發明之實施形態,不過此等實施形態是一個例子,在不脫離申請專利範圍之範圍內可作各種變更來實施。此外,本發明之權利範圍當然不限定於此等實施形態。The embodiments of the present invention have been described above by way of example only, and the embodiments of the present invention are described by way of example only.
