Replaceable self-returning joint energy consumption connecting device
The invention discloses a replaceable self-returning joint energy consumption connecting device, and relates to the technical field of wind power generation. The device is composed of a pull plate anda pressing plate, wherein the pull plate and the pressing plate are embedded and fixed together through a corrugated surface, and sand blasting treatment is carried out on a contact surface. The pullplate comprises a T-shaped pull plate and a U-shaped pull plate; an I section of the T-shaped plate and an II section of the U-shaped plate are punched in the thickness direction, are connected in series through a screw rod and apply pre-tension. The pressing plate is divided into an upper pressing plate and a lower pressing plate; the pressing plates are connected through a prestress pull rod; and a corrugated groove position is reserved in the pressing plate so as to be embedded with the corrugated surface of the pull plate. C-shaped steel is welded to the outer surface of the pressing plate in the length direction to enhance the outer rigidity of the surface. According to the device, input energy is dissipated through the friction force of the contact surface and the corrugated surface, and self-returning of a component is achieved through the returning force of the prestress pull rod. The device is easy to replace, clear in force transmission, easy and convenient to install, goodin energy consumption effect and suitable for connecting joint energy consumption of a wind power lattice type tower frame, and has wide engineering application prospects in other lattice type fields.
本发明公开了一种可更换的自复位节点耗能连接装置，涉及风力发电技术领域。该装置由拉板和压板组成，拉板与压板之间通过波纹面嵌固在一起，并对接触面做喷砂处理。所述的拉板包括T形拉板和U形拉板两部分，T形板I段和U形板II段沿厚度方向打孔，利用螺杆串接并施加预拉力。所述压板分为上压板与下压板，压板之间通过预应力拉杆连接，压板预留波形槽位以便与拉板波纹面嵌合。压板外表面沿长度方向焊接C形钢加强面外刚度。该装置通过接触面和波纹面的摩擦力耗散输入的能量，通过预应力拉杆的回复力实现构件的自复位。该装置更换简单，传力明确，安装简便，耗能效果好，适用于风电格构式塔架的连接节点耗能，在其他格构式领域也具有广阔的工程应用前景。
