Steel support structure capable of automatically regulating and controlling axial force along with dynamic load of foundation pit
The steel support structure comprises a steel support body and an axial force adjusting device, the axial force adjusting device comprises an outer shell and an inner shell, one end of the outer shell is connected to an outer ring of a bearing, the inner shell is coaxially arranged in the outer shell, one end of the inner shell is connected to an inner ring of the bearing, and the other end of the inner shell is coaxially arranged in the inner ring of the bearing. A hydraulic cylinder is arranged in the inner shell, an ejector rod is arranged at one end of the hydraulic cylinder, external threads are arranged on the periphery of the ejector rod, a locking mechanism is arranged on the inner wall of the outer shell, the locking mechanism is provided with internal threads matched with the external threads of the ejector rod, and when the hydraulic cylinder cannot drive the ejector rod to extend, the outer shell is rotated to drive the locking mechanism to rotate around the ejector rod. And the locking mechanism not only plays a locking role, but also is used as a driving mechanism capable of driving the ejector rod to do linear motion, so that the axial force can be conveniently adjusted in time when the device breaks down, and potential safety hazards are eliminated.
本发明公开了一种随基坑动载自动调控轴力的钢支撑结构，包括钢支撑主体和轴力调节装置，轴力调节装置包括外壳体和内壳体，外壳体一端连接在轴承外圈，内壳体同轴设于外壳体内部，内壳体一端连接于轴承内圈上，轴承嵌设于安装板上，内壳体内设有液压缸，液压缸的一端设有顶杆，顶杆外周设有外螺纹，外壳体内壁上设有锁定机构，锁定机构设有与顶杆外螺纹相适配的内螺纹，当出现液压缸无法驱动顶杆伸长时，旋转外壳体带动锁定机构绕顶杆转动，使顶杆向围护墙方向进行直线运动以补偿轴力，避免轴力失效，锁定机构不仅起到锁定作用，同时用作能够带动顶杆进行直线运动的驱动机构，方便在装置出现故障时能及时调整轴力，以消除安全隐患。
