具体实施方式 detailed description
下面结合附图对本发明进行详细描述。 The present invention will be described in detail below in conjunction with the accompanying drawings.
如图1至图7所示,本发明包括1左拉耳、2缸体、3活塞杆、4缸盖Ⅰ、5外滑体、6摩擦片、7增压活塞、8缸盖Ⅱ和9右拉耳。 As shown in Figures 1 to 7, the present invention includes 1 Zola ear, 2 cylinder blocks, 3 piston rods, 4 cylinder head I, 5 outer sliding body, 6 friction plates, 7 booster piston, 8 cylinder head II and 9 Pull the ear right.
如图1所示,缸体2为圆筒状结构且水平放置,缸体左端通过螺纹与左拉耳相连接,缸盖Ⅰ4通过螺纹安装在缸体2中部,缸盖Ⅱ8通过螺纹安装在缸体2右端,缸盖Ⅰ4、缸盖Ⅱ8中间开有通孔,活塞杆3两端的细长杆分别插入到缸盖Ⅰ4、缸盖Ⅱ8中间的通孔中,活塞杆3中部活塞与缸体2内壁接触,缸体2、缸盖Ⅰ4、缸盖Ⅱ8和活塞杆3构成密闭油腔,如图4所示,活塞杆3中部活塞上开有两个阻尼小孔31,阻尼小孔的作用是当活塞杆移动时让油液通过阻尼小孔产生阻尼力,如图2所示,缸体2侧壁上开有四个通孔21,四个通孔21中设有四个增压活塞7,缸体2外壁与通孔21相对应的位置安装有四个摩擦片6,摩擦片6内壁与增压活塞7相接触,外壁与外滑体5内壁相接触,外滑体5套在缸体2外部,一端敞口另一端通过螺纹与右拉耳9相连,右拉耳9内部开有螺纹孔,与活塞杆一端相连。 As shown in Figure 1, the cylinder body 2 is a cylindrical structure and placed horizontally. The left end of the cylinder body is connected to the left pull ear through threads. At the right end of body 2, there is a through hole in the middle of cylinder head I4 and cylinder head II8. The inner walls are in contact, and the cylinder body 2, cylinder head I4, cylinder head II8 and piston rod 3 form a closed oil chamber. As shown in Figure 4, there are two small damping holes 31 on the piston in the middle of the piston rod 3. The function of the small damping holes is When the piston rod moves, let the oil pass through the damping holes to generate damping force, as shown in Figure 2, four through holes 21 are opened on the side wall of the cylinder body 2, and four booster pistons 7 are arranged in the four through holes 21 , four friction plates 6 are installed at the positions corresponding to the outer wall of the cylinder body 2 and the through hole 21, the inner walls of the friction plates 6 are in contact with the booster piston 7, the outer walls are in contact with the inner walls of the outer sliding body 5, and the outer sliding body 5 is set in the cylinder Outside the body 2, one end is open and the other end is connected to the right pull ear 9 through threads, and the inside of the right pull ear 9 has a threaded hole, which is connected to one end of the piston rod.
安装时,左拉耳1与地基相连,右拉耳9与震源相连,工作时,右拉耳9、外滑体5和活塞杆3与震源一起振动,活塞杆3中部活塞在油腔内左右移动,由于阻尼小孔31的作用当油液通过时会产生粘滞阻尼力,达到减震的目的,同时,当活塞杆3向左移动时,油腔左半部分的油压会升高,油液压力通过增压活塞7传递到摩擦片6上,从而摩擦片6与外滑体5之间产生挤压摩擦,从而达到减震的目的,当活塞杆3向右移动时,油腔右半部分的油压会升高,油液压力通过增压活塞7传递到摩擦片6上,从而摩擦片6与外滑体5之间产生挤压摩擦,从而达到减震的目的,这样该粘滞-摩擦阻尼器就实现了阻尼力由粘滞阻尼力和摩擦阻尼力两部分构成的目的,同时也实现了当震源不震动时,摩擦片与外滑体之间没有压力,延长摩擦片的使用寿命,降低使用成本的目的。 During installation, the left pull ear 1 is connected with the foundation, and the right pull ear 9 is connected with the seismic source. When working, the right pull ear 9, the outer sliding body 5 and the piston rod 3 vibrate together with the shock source, and the piston in the middle of the piston rod 3 is left and right in the oil chamber. Due to the function of the damping hole 31, when the oil passes through, a viscous damping force will be generated to achieve the purpose of shock absorption. At the same time, when the piston rod 3 moves to the left, the oil pressure in the left half of the oil chamber will increase. The oil pressure is transmitted to the friction plate 6 through the booster piston 7, so that extrusion friction occurs between the friction plate 6 and the outer sliding body 5, so as to achieve the purpose of shock absorption. When the piston rod 3 moves to the right, the oil chamber moves to the right Half of the oil pressure will rise, and the oil pressure will be transmitted to the friction plate 6 through the booster piston 7, so that extrusion friction will be generated between the friction plate 6 and the outer sliding body 5, so as to achieve the purpose of shock absorption, so that the viscous The hysteresis-friction damper realizes the purpose that the damping force is composed of two parts: the viscous damping force and the frictional damping force. At the same time, when the source does not vibrate, there is no pressure between the friction plate and the outer sliding body, and the life of the friction plate is extended. service life and reduce the cost of use.
