The invention discloses a universal anchorage device test centering lifting device. The universal anchorage device test centering lifting device comprises a base, a bearing table and a lifting device,wherein the lifting device is connected between the base and the bearing table and controls the bearing table to ascend and descend; the lifting device comprises a lead screw and four plate type rods; the lead screw is horizontally arranged and screwed into a nut; the four plate type rods are arranged in a diamond shape on a vertical plane and are hinged to the lead screw and the nut respectively; the two plate type rods located on the upper side of the diamond shape are hinged to the bearing table; and the two plate type rods located on the lower side of the diamond shape are hinged to the base, so that the nut can move linearly along the lead screw by rotating the lead screw, and the bearing table is driven to ascend and descend through the four plate type rods. Smooth and continuous lifting and leveling of accessories such as a loading jack and a load sensor in an anchorage device mechanical property test are realized, time and labor are saved, and the operation safety and reliability are improved.
本发明公开了一种具有通用性的锚具试验对中升降装置,包括底座、承重台和升降装置,所述升降装置连接在底座与承重台之间控制承重台的升降,所述升降装置包括丝杠和四根板式杆,所述丝杠水平设置并旋入螺母中,四根板式杆在竖直平面呈菱形排布并分别与丝杠和螺母铰接,位于菱形上侧的两板式杆与承重台铰接,位于菱形下侧的两板式杆与底座铰接,使得转动丝杠能够使螺母沿丝杠直线运动,从而通过四根板式杆带动承重台升降。本发明实现了锚具力学性能试验中加载千斤顶和荷载传感器等配件的平滑连续升降调平,既省时省力,也提高了操作的安全性和可靠性。
