Anti-falling device for well
The anti-falling device for the well comprises an outer ring support, an inner ring support and elastic pull rods, the outer ring support is coaxially and internally supported and fixed to the well wall, the inner portion of the outer ring support is circumferentially distributed, is in radial limiting hanging connection and is axially and elastically connected with one ends of the elastic pull rods, and the other ends of the elastic pull rods penetrate through the inner ring support in a hanging connection mode; the outer ring support is of a multi-petal type annular splicing structure, and a plurality of hanging boxes are fixedly arranged on the circumferential inner wall of the outer ring support. A plurality of long holes are formed in the hanging boxes, elastic pull rods are inserted into the long holes in a one-to-one correspondence and penetrating mode, the inner walls of the long holes are in sliding fit with the outer walls of the elastic pull rods, and the elastic pull rods are hung on the side walls of the end faces of the long holes in a radial limiting mode. The falling impact resistance rigidity of the anti-falling device for the well can be effectively improved, the situation that the impact resistance limit is reduced due to aging for a long time is avoided, and the anti-falling device is particularly suitable for falling prevention of the deep well.
本发明公开了一种井用防坠落装置，包括外圈支架、内圈支架及弹性拉杆，其中外圈支架同轴内撑固定在井壁上，外圈支架的内部周向分布、径向限位挂接并轴向弹性连接多根弹性拉杆的一端，该弹性拉杆的另一端均穿透挂接在内圈支架上；外圈支架为多瓣式环向拼接结构，该外圈支架的周向内壁上固设有多个挂盒；挂盒上均开设有多个长孔，该长孔内一一对应并穿透插接弹性拉杆，长孔的内壁与弹性拉杆的外壁滑动配合，且长孔的端面侧壁径向限位挂接弹性拉杆。该装置可有效提高井用防坠落装置抗坠落冲击的刚度，且不会因年久老化而导致抗冲击极限下降，尤其适适合深井防坠落使用。
