Novel standard penetration test elevator
The invention provides a novel standard penetration test elevator which can be widely applied to the field of geotechnical engineering investigation. The device specifically comprises a sleeve, a guide rod is arranged in the sleeve in a sleeved mode, the guide rod is divided into an upper section and a lower section, the lower section is an equal-diameter rod, the upper section is a variable-diameter rod, and the diameter of the variable-diameter rod is gradually reduced; two swing rods which are symmetrically distributed are hinged to the bottom face of the sleeve, and first extrusion balls are arranged at the bottom ends of the swing rods. A cushion block is fixedly arranged at the bottom of the guide rod, a center penetrating hammer is arranged above the cushion block in a sleeving mode, and a lifting clamping ring is arranged above the center penetrating hammer in a sleeving mode. A right-angle ball containing cavity is formed in the lifting clamping ring, and a first extrusion ball and a second extrusion ball are arranged in the right-angle ball containing cavity. The first extrusion ball is located in a lower groove of the right-angle ball containing cavity, the second extrusion ball is located in a right groove of the right-angle ball containing cavity, and a through hole with the diameter smaller than that of the second extrusion ball is formed in the outer wall of the lifting clamping ring. An annular cavity with the outer diameter larger than the outer diameter of the lifting clamping ring and the inner diameter equal to the outer diameter of the lifting clamping ring is formed in the center penetrating hammer.
本发明提供一种新型标准贯入试验提引器，可广泛应用于岩土工程勘察领域；具体包括套管，套管内套设有导向杆，导向杆分为上下两段，下段为等径杆，上段为变径杆，变径杆的直径逐渐减小；套管底面铰接有对称分布的两根摆动杆，摆动杆的底端设置有第一挤压球；导向杆底部固定设置有垫块，垫块上方套设有穿心锤，穿心锤上方套设有提引卡环；提引卡环的内部开设有直角容球腔，直角容球腔内有第一挤压球和第二挤压球；第一挤压球位于直角容球腔的下槽内，第二挤压球位于直角容球腔的右槽内，提引卡环外壁上开设有直径小于第二挤压球直径的通孔；穿心锤内开设有外径大于提引卡环外径，内径等于提引卡环外径的环形空腔。
