Pile foundation anchor rod anti-pulling testing device
The invention relates to a testing device, in particular to a pile foundation anchor rod anti-pulling testing device which comprises an air cylinder, a moving ring, first elastic pieces, a clamping block and the like, the moving ring is arranged in the air cylinder in a sealed sliding mode, the multiple first elastic pieces are connected between the top of the moving ring and the top in the air cylinder, and an inclined face is arranged on the lower portion in the moving ring. The inclined face gradually extends to the circle center position of the moving ring from bottom to top, and a plurality of clamping blocks used for clamping the anchor rod are evenly arranged on the inclined face of the moving ring in a sliding mode at intervals. The air pump can inject air into the air cylinder, the air pushes the moving ring to move downwards, the moving ring extrudes the clamping blocks, the clamping blocks are closed, the anchor rod is clamped, the moving ring exerts downward pulling force on the anchor rod, an anti-pulling test is conducted on the anchor rod, the ejector rod can abut against the construction position, the air cylinder is prevented from inclining, and the test result is more accurate; and through the action of the second elastic piece, the ejector rod can adapt to different construction positions.
本发明涉及一种测试装置，尤其涉及一种桩基锚杆抗拔测试装置，包括有气筒、移动环、第一弹性件和夹块等，气筒内密封滑动式设有移动环，移动环顶部和气筒内顶部之间连接有多个第一弹性件，移动环内下部设有斜面，该斜面从下往上逐渐向移动环的圆心位置延伸，移动环的斜面上均匀间隔的滑动式设有多个用于将锚杆夹住的夹块。本发明的气泵可以将空气注入气筒内，空气推动移动环向下移动，移动环挤压夹块，使夹块合拢，将锚杆夹住，移动环对锚杆施加向下的拉力，对锚杆进行抗拔测试，顶杆可以顶在施工位置，避免气筒发生倾斜，使得测试结果更加准确，并且通过第二弹性件的作用，能够使顶杆适应不同的施工位置。
