Friction test adjustable limiting device

摩擦试验可调限位装置

Abstract

一种摩擦试验可调限位装置,包括承力套筒,调压板安装在承力套筒内,调压板上分布有多个通孔,调压板通过螺杆与耳板连接,螺杆上设有定位螺母和限位螺母。耳板上设有导向螺杆,导向螺杆上设有固定螺栓。本发明提供的摩擦试验可调限位装置,由于采用了调压板通过螺杆与耳板连接的结构,实现了调压板可移,在进行摩擦试验试验时,可同时满足被动端测力油压及钢束锚固时对锚固夹片的位置要求,解决多次造成摩擦试验测试数据不准确或钢束锚固时钢绞线产生断裂及滑移的问题,能确保试验钢束的拉力正常传递到被测部位,测试完毕钢束得到可靠锚固。
The invention discloses a friction test adjustable limiting device which comprises a bearing sleeve, wherein a pressure adjustment plate is arranged in the bearing sleeve; a plurality of through holes are formed in the pressure adjustment plate; the pressure adjustment plate is connected with a lug plate through screws; positioning nuts and limiting nuts are arranged on the screws; guide screws are arranged on the lug plate; fixing bolts are arranged on the guide screws. According to the friction test adjustable limiting device, due to adoption of a structure that the pressure adjustment plate is connected with the lug plate through the screws, the pressure adjustment plate is movable; in the friction test, a position requirement for an anchoring fixed sheet during passive end oil pressure measurement and steel bundle anchoring can be met; the problem of inaccurate friction test data or fracture and slippage of a steel stranded wire during the steel bundle anchoring is solved; tension of a test steel bundle can be normally transmitted to a measured part; after the test is finished, the steel bundle can be reliably anchored.
