运动锁定装置 Movement of the locking device

技术领域 FIELD

[0001] 本发明涉及一种用于在低速载荷下允许构件相互运动,而在高速载荷下锁定构件运动的阻尼装置,特别是用于桥梁活动支座中的运动锁定装置。 [0001] The present invention relates to a member for allowing mutual movement of the load at low speed, while the movement of the locking member damping means at high loads, in particular for the movement of the movable carriage bridge locking means.

背景技术 Background technique

[0002] 地震作为不能避免的自然灾害,会造成生命财产的损失。 [0002] earthquake as natural disasters can not be avoided, will result in the loss of life and property. 而地震对于桥梁的破坏直接损失更大,因此对于桥梁建设而言,如何提高桥梁的抗震能力并降低地震对桥梁的坡环,是十分重要的问题。 The earthquake destroyed the bridge for direct losses greater, so for bridge construction, how to improve the bridge's seismic capacity and reduce the seismic ring slope of the bridge, is a very important issue.

[0003] 对于桥梁抗震来说,长期以来人们往往是加大梁、柱、剪力墙用来被动抵抗,而非采用更主动的办法去减小结构所受地震力。 [0003] For the bridge seismic, a long time people tend to increase as beams, columns, shear walls for passive resistance, rather than adopt a more proactive approach to reduce the structural seismic forces suffered. 到了二十世纪末期,这种现象有了很大的改变。 By the late twentieth century, this phenomenon has changed dramatically. 人们在增强传统结构构件之外,吸收航空和机械等其他领域的成果,采取在结构上另外安装新的装置来减小结构所受的地震力,例如:利用隔震措施或各种阻尼器的减震系统,以及在高层建筑中已投入实用的被动质量调谐阻尼系统和主动控制减震系统。 People reinforcing member outside the conventional structure, the absorption results in other areas of aviation and machinery, to adopt a new device structure to reduce the additional seismic forces suffered mounting structure, for example: using a variety of measures or isolation dampers damping system, and has been put into practical passive tuned mass damper system in high-rise buildings and active damping control system. 这些方法归纳起来形成了目前桥梁抗震领域常用的三种抗震设计方法,即传统结构抗震设计方法,近些年出现的减隔震结构抗震设计方法和结构控制设计方法。 These methods are summed together to form a bridge commonly used three kinds of seismic design seismic art methods, i.e. conventional seismic design method, the design method of seismic isolation Save and control structure design method emerged in recent years.

[0004] 减隔震技术是通过引入隔震装置改变结构在地震中的动力响应特性,从而减少地震输入,外加耗能机制作为主要的抗震构件,而以结构构件抗震为辅。 [0004] by introducing the power isolation technology is isolated by means of structural changes in seismic response characteristic, thereby reducing the seismic input, plus seismic energy dissipation mechanism as the main component, and to supplement the seismic structural member. 在该方法中,基本目的是要大大减小传递到结构上的地震力和能量,其抗震能力是通过延长结构周期,增加耗能能力来实现。 In this method, the basic object is to greatly reduce the seismic forces and energy transmitted to the structure, the seismic capability is achieved by extending the period of the structure, to increase the energy dissipation capacity. 设计依据一般包括全保护隔震设计、部分保护隔震设计两种设计原则。 Including full protection design according to the general isolation design, two design principles partially protected isolation design. 从各国的桥梁减隔震应用情况来看,目前桥梁减隔震设计中已采用的主要是分层橡胶支座、 铅芯橡胶支座和高阻尼橡胶支座,且通常安装在桥梁上部结构与桥墩或桥台之间。 Seismic Isolation States application from the bridge, the current bridge Save isolation design has been adopted mainly layered rubber bearing, LRB, and high damping rubber bearing, and is usually installed in the upper portion of the bridge structure and between the piers or abutments.

[0005] 目前针对这种情况研究和使用较多的是从减隔震设计的思路出发,将制动墩支座做成减隔震支座进行隔震设计,但是该方法也有它的适用范围,因为桥梁是否适合采用隔震设计,应从桥梁在地震时和正常使用时两个方面来考虑,并结合其延长桥梁结构固有周期及吸收能量能力的效果进行研究后方可决定。 [0005] and more research is currently used for this situation is starting from the idea of ​​reducing isolation design, the brake support piers were made of isolation bearing isolation design, but this method also has its scope only after the decision, because if the bridge design suitable for isolation, should the bridge at the time of the earthquake and the normal use of two aspects to consider, in conjunction with its extended bridge structures and effects of the natural cycle of energy absorption capacity of research.

[0006] 而且,减隔震设计也面临着其它问题:首先,因为减隔震设计一般是通过使用低刚度的支座来改变延长结构的动力周期,这样由于支座刚度较低使得它自身的变形在地震以外的工况下会增大,进而可能会影响整体系统的稳定及自身的稳定,所以每个减隔震系统的设计都需要针对具体工程情况进行仔细计算和设计,以保证在常规作用和地震作用下结构强度、静动刚度和稳定性能够满足两个时期各自的要求,这需要设计单位有很高的减隔震设计理论和计算分析能力;同时,从隔震产品角度来讲,由于环保的原因,发达国家现在已经较少使用原本减隔震支座中的主力——铅芯橡胶支座,而另一个主要的隔震产品—— 分层橡胶支座由于需要控制它在地震下过大的变形,一般需要配合阻尼器来共同使用,这需要各个隔震产品的成熟和配合的可靠,同时 [0006] Further, isolation Save design faces other problems: First, because the design is generally isolated Save power changing period is extended by using a configuration of low rigidity of the support, so that due to the lower support stiffness of its own deformation conditions other than earthquakes will increase, which may affect the stability and the stability of the overall system itself, so each decrease isolation system design need to be carefully calculated and designed for the specific project circumstances, in order to ensure regular under the effect of earthquake and structural strength, static and dynamic stiffness and stability to meet the requirements of the respective two periods, which requires a high design units seismic isolation design theory and calculation of capacity; the same time, the product isolated from the perspective of , because of environmental reasons, less developed countries are now using the original isolation bearing in the main - lead rubber bearing, the isolation and the other main products - layered rubber bearings due to the need to control it under earthquake excessive deformation, generally require use together with the damper, which requires mature and reliable individual with isolation products, while 增加了使用的复杂度和成本,而高阻尼橡胶支座需要保证能生产出大量性能稳定和可靠产品;另外,从耐久性角度,使用减隔震支座后,整个结构的抗震将依赖隔震支座来独自承担,而隔震支座目前多为橡胶和钢板胶合结构,在风吹日晒等条件下的使用寿命一般低于盆式支座,这将成为整个抗震系统的隐忧•'最后,从工程造价角度,桥梁结构使用隔震支座时,一般每个支撑位置都需要使用隔震支座, 这也使得整个系统成本大大提高。 It increases the complexity and cost of use, and high-damping rubber bearing can produce a large need to ensure stable and reliable product performance; Furthermore, from the perspective of durability, the use of isolation bearing, the overall structure will depend on the seismic isolation stand to bear alone, and isolation bearings currently mostly gluing of rubber and steel structure, life under the sun and wind and other conditions are generally lower than pot bearings, this will be the entire system of seismic worries • 'final when, from the perspective of project cost, bridge structures using seismic isolation bearings, each support position generally require the use of isolation bearings, which also makes the overall system cost is greatly improved.

[0007] 为此,本发明的申请人提出一种桥梁抗震活动支座,支座的上部结构安装在梁体上,支座的下部结构安装在墩柱上。 [0007] For this reason, the present applicant proposes a bearing bridge seismic activity, the superstructure bearing is mounted on the beam member, the lower portion of the support structure is mounted on the pier. 在低速载荷下,支座上部结构可以相对支座下部结构运动。 Under low load, the upper support structure may be a lower support structure relative motion. 但是在高速载荷下(例如发生地震时),可以锁定支座上部结构和下部结构,使得梁体和墩柱刚性地连成一体。 However, at high loads (e.g. when an earthquake), can lock the upper support structure and a lower structure, such that the beam is rigidly and integrally connected Pier. 这样地震水平载荷由桥梁中的所有支座分担,而不单独由隔震支座承担,从而改善了墩柱的受力状况,有利于提高桥梁的抗震能力。 Such seismic horizontal load bearing bridge shared by all in, and not solely responsible for the isolation bearing, thereby improving the situation by force piers, help to improve the seismic capacity of the bridge.

[0008] 现有的流体阻尼器主要是用于大跨度桥梁、大柔度桥梁上,由于耗能需要大的位移量,就需要阻尼器产生很大的位移,来吸收能量。 [0008] The conventional fluid damper is mainly used for long-span bridges, large flexibility bridge, requires a large energy consumption due to the amount of displacement, it is necessary to generate a large displacement of the damper to absorb energy. 因而,这种现有流体阻尼器不能满足在低速载荷下允许相对运动,在高速载荷下锁定运动的要求,因而无法应用到该桥梁抗震支座中。 Accordingly, such a conventional fluid damper can not meet allow relative movement at low loads, movement of the lock requires a load at high speed, and therefore can not be applied to the seismic support the bridge.

[0021] 如图1所示,本发明的运动锁定装置包括缸体1和活塞杆2。 [0021] As shown in FIG 1, the movement of the locking device of the present invention comprises a cylinder 1 and the piston rod 2. 缸体1的两端设有端盖3,用于密闭缸体1。 Both ends of the cylinder 1 is provided with a cover 3 for a cylinder 1 closed. 端盖3上设有开口供活塞杆2的两端从端盖中伸出。 Cap 3 provided with an opening for the piston rod 2 projects from both ends of the end cap. 活塞杆2中部形成活塞头21,活塞头21位于缸体1中将其分成第一腔室11和第二腔室12。 Central rod 2 forming the piston head 21, the cylinder 21 is located in the piston head 1 which is divided into a first chamber 11 and second chamber 12.

[0022] 活塞头21的外径小于缸体1的内径,从而在两者之间形成细微的间隙22。 [0022] The outer diameter of the piston head 21 than the inner diameter of the cylinder 1, so that a fine gap 22 is formed therebetween. 在一较佳实施例中,该间隙的径向距离例如为1mm。 In a preferred embodiment, the radial distance of the gap, for example 1mm. 第一腔室11和第二腔室12通过该间隙22连通。 12 communicates the first chamber and the second chamber 11 through the gap 22.

[0023] 缸体1内充满阻尼介质4。 [0023] 1 the cylinder 4 is filled with damping medium. 阻尼介质4可通过缸体1壁面上的通孔23注入或卸出缸体1。 Damping medium through the through holes 4 in the wall surface of the cylinder 23 is discharged or injected into the cylinder 1. 阻尼介质4注入后,需将通孔23用密封件(未显示)密封,防止泄漏。 After injecting the damping medium 4, with the need to seal the through hole 23 (not shown) sealed to prevent leakage.

[0024] 由于间隙22较小,当活塞杆2在低速载荷下进行运动时,阻尼介质4可通过间隙22从第一腔室11缓慢地流到第二腔室12,或者从第二腔室12缓慢地流到第一腔室11。 [0024] Due to the small gap 22, when the piston rod 2 at a low speed when moving the load, the damping medium through the gap 4 may be slowly flowing from the first chamber 22 second chamber 11 12, or from the second chamber 12 slowly flows to the first chamber 11. 在这种情况下,活塞杆2可以相对缸体1沿轴向运动。 In this case, the piston rod 2 can move axially relative to the cylinder 1.

[0025] 端盖3设有密封槽和密封件以密封阻尼介质4。 [0025] The end cap is provided with a sealing groove 3 and a seal 4 for sealing the damping medium. 具体地,端盖3上在靠近活塞杆2 的内壁上从外至内依次第一密封槽31、第二密封槽32、第三密封槽33和第四密封槽34 ;在靠近缸体1的外壁上设有第五密封槽35。 In particular, the end cap 3 in the inner wall near the piston rod 2 sequentially from the outer to the inner groove 31 of the first seal, the second seal groove 32, the third 33 and the fourth seal groove 34 seal groove; close to the cylinder 1 the fifth wall is provided with an outer seal groove 35. 第一密封槽31内设置有第一密封环310,第四密封槽34内设有第二密封环340。 A first seal groove 31 is provided with a first seal ring 310, the fourth seal groove 34 equipped with a second sealing ring 340. 第二密封槽32内设有第一导向环320,第三密封槽33内设有第二导向环330。 The second seal groove 32 features a first guide ring 320, a third seal groove 33 equipped with a second guide ring 330. 第五密封槽35内设有卡环350。 The fifth seal groove 35 features a snap ring 350. 当安装到如图2所示的活动桥梁支座上时,缸体1与支座的上部结构50固定,活塞杆与支座的下部结构60固定,从而在低速条件下可以让支座上部结构50相对于支座下部结构60水平运动。 When mounted on the movable bridge bearings shown in FIG. 2, the cylinder block 1 and the upper bearing structure 50 fixed to the lower support structure 60 and the piston rod is fixed, which allows the upper support structures at low speed 50 with respect to the movement of the support structure 60 a lower level.

[0026] 若活塞杆2受到高速载荷,例如地震发生时的水平载荷,由于间隙22较小,阻尼介质4无法快速通过间隙22在两个腔室内流动,从而对活塞体21形成极大的反向阻力。 [0026] When the piston rod 2 by the high-speed loading, for example when a horizontal load of an earthquake, since the gap 22 is small, the damping medium 4 can not quickly flow through the gap 22 in the two chambers, the piston body 21 formed thereby an extremely large to resistance. 此时,活塞杆2无法相对缸体1运动,相当于将活塞杆2锁定。 At this time, the piston rod 2 can not be relative movement of the cylinder 1, the piston rod 2 corresponds to the lock. 通过此方式,将桥梁支座锁定, 让地震载荷由桥梁上所有的支座一起分担。 In this way, the bridge bearings to lock, and enable seismic load shared together by all of the bearings on the bridge.

[0027] —般,流体阻尼器中的阻尼力由下列公式得出:F = C · Va [0027] - generally, the damping force of the fluid damper is given by the following equation: F = C · Va

[0028] 上式中,F为阻尼力,C为阻尼系数,V为活塞杆的速度,α为速度指数。 [0028] In the above formula, F is the damping force, C is the damping coefficient, V is the velocity of the piston rod, α is a velocity index.

[0029] 现有的流体阻尼器,通常选择a = 0. 1为速度指数,因而随着速度的上升,阻尼力而缓慢增大。 [0029] The conventional fluid damper, is usually selected as a = 0. 1 speed index, and therefore with the increase in speed of the damping force increases slowly. 在本发明中,选择a >2为速度指数。 In the present invention, select a> 2 is the speed index. 这样,阻尼力随着速度上升而急剧上升,受此阻力,活塞杆2无法相对于缸体1运动而锁定。 Thus, the damping force rises rapidly as the speed rises, by this resistance, the piston rod 2 can not move relative to the cylinder 1 is locked.

[0030] 图3所示为本发明与现有流体阻尼器的曲线比较图,其中横轴表示活塞杆的速度V,纵轴表示阻尼力F。 [0030] FIG. 3 shows a graph comparing the conventional fluid damper according to the present invention, wherein the horizontal axis represents the piston velocity V, and the vertical axis represents damping force F. 曲线A表示本发明在a =2时实施例的速度一阻尼力比率图,曲线B表示现有阻尼器的速度一阻尼力比率图,直线C表示两者的分界线。 Curve A represents the present invention, when the second speed ratio of the damping force according to an embodiment in FIG. A =, curve B represents the speed of a conventional damping force damper ratio map, line C represents the boundary between the two. 从图3可以看出,现有阻尼器随着速度增加,阻尼力也会逐渐增加。 As can be seen from Figure 3, the conventional damper as the speed increases, the damping force will gradually increase. 而本发明的速度在同样增加的情况下,阻尼力上升的斜率很大,远远超出现有阻尼器的升幅,因此很快就能达到使得活塞杆2锁定的预定值。 And the speed in the case where the present invention is also increased, the damping force of the rising slope of the large increases far beyond the conventional damper, so soon reaches a predetermined value so that the locking rod 2.

[0031] 本发明采用性能稳定的有机硅油作为阻尼介质,该有机硅油的塑性粘度0.82,反弹率80%,塌落度12.7mm。 [0031] The stability of the silicone oil as the damping medium of the present invention, the plastic viscosity silicone oil 0.82, 80% rebound, slump 12.7mm. 有机硅油是分子结构中含有硅元素的高分子合成材料,其分子主链是一条由硅原子和氧原子交替组成的骨架。 Polymer composite materials is silicone oil molecular structure containing silicon element, which is a main chain backbone consisting of alternating silicon and oxygen atoms. 在本发明中,该硅脂材料的有机基质为甲基硅油,无机填料为白炭黑,分子量为6787。 In the present invention, the organic matrix material is silicone grease methyl silicone oil, inorganic filler is silica, a molecular weight of 6787. [0032] 这种特殊的分子结构和组成使硅油集无机物的特性和有机物的功能于一身,不但具有无机物二氧化硅的耐高温、耐气候老化、耐臭氧、电绝缘、耐燃、无毒无腐蚀和化学性稳定、无色无味、不挥发等优异性能,而且具有高分子材料高粘性的特性。 [0032] The composition of this particular molecular structure of silicone oil collector inorganic and organic features and functionality in one, having only silica refractory inorganic material, weathering resistance, ozone resistance, electrical insulation, flame resistance, non-toxic non-corrosive and chemically stable, colorless, odorless, non-volatile, excellent performance, and it has a characteristic highly viscous polymer material.
