The invention provides an elevator safety tongs structure, and belongs to the technical field of safety tongs. The elevator safety tongs structure comprises first wedge blocks, roller pin rows, secondwedge blocks, a lifting rod, fixing pieces, connecting pieces and expansion extrusion pieces. According to the elevator safety tongs structure, through each fixing piece, one end of the correspondingfirst wedge block and one end of a guide rail are kept parallel and the distance between the end of the first wedge block and the end of the guide rail is unchanged, and thus the situation that the first wedge block is inclined so that it cannot be convenient for the corresponding second wedge block to extend to the position between the first wedge block and the guide rail to stop the first wedgeblock is avoided; through each connecting piece, the other end of the corresponding first wedge block and the corresponding second wedge block are respectively and rotatably connected to an elevatorcar, and the lifting rod pulls the second wedge block to move towards the direction close to the first wedge block; and when each expansion extrusion piece is impacted by the lower end of the elevatorcar, the expansion extrusion piece expands and extrudes the lower end of the corresponding second wedge block to make the second wedge block move towards the direction close to the first wedge block,so that the second wedge block is accelerated to move towards the direction of the first wedge block, and the efficiency of stopping the elevator car is improved.
本发明提供一种电梯安全钳结构,属于安全钳技术领域。该电梯安全钳结构包括第一楔形块、滚针排、第二楔形块、提拉杆、固定件、连接件和膨胀挤压件。本发明中的固定件将第一楔形块一端与导轨一端保持平行且两者之间的距离不变,避免第一楔形块发生倾斜而不利于第二楔形块伸入第一楔形块和导轨之间以将第一楔形块制停,连接件分别将第一楔形块另一端、第二楔形块转动连接于轿厢,提拉杆拉到第二楔形块朝着靠近第一楔形块的方向运动,膨胀挤压件在其受到轿厢下端的撞击而膨胀挤压第二楔形块下端使得第二楔形块朝着靠近第一楔形块的方向运动,从而加速推动第二楔形块朝着第一楔形块的方向运动,提高制停轿厢的效率。
