The invention relates to an integral dropper anti-abrasion protection device. The device is characterized in that a clamping groove and a boss I extend from an inner end surface of a left end protection piece of the integral dropper anti-abrasion protection device, and an umbrella-shaped buckle extends from the center of the boss I, a clamping column and a boss II extend from an inner end surfaceof a right end protection piece, and a through hole is formed in the center of the boss II, the left end protection piece and the right end protection piece are oppositely arranged on two sides of thewhole dropper heart-shaped protection ring, the clamping column is inserted into a clamping groove, the boss I and the boss II are embedded into the whole dropper heart-shaped protection ring, the umbrella-shaped buckle penetrates through a through hole and then is clamped on an outer end surface of the right end protection piece to connect the left end protection piece and the right end protection piece together, inclined planes on two sides of the trapezoids at upper parts of the boss I and the boss II are tightly attached to two inner side surfaces of the integral dropper heart-shaped protective ring, and a certain gap is formed between a semicircular boss at lower parts of the boss I and the boss II and the top of the integral dropper lifting ring. The device is advantaged in that abrasion of a dropper line at the bottom of the heart-shaped protective ring can be effectively prevented, and safe operation of the line is guaranteed.

    一种整体吊弦防磨防护装置,其左端防护件内端面延伸有卡槽、凸台Ⅰ,所述凸台Ⅰ中央延伸有伞形卡扣;其右端防护件内端面延伸有卡柱、凸台Ⅱ,所述凸台Ⅱ中央设有通孔;所述左端防护件和右端防护件相对设置在整体吊弦心形护环两侧,且所述卡柱插装在卡槽内,所述凸台Ⅰ、凸台Ⅱ嵌入整体吊弦心形护环内,所述伞形卡扣穿过所述通孔后卡在右端防护件的外端面,将左端防护件和右端防护件连接在一起;并使所述凸台Ⅰ、凸台Ⅱ上部梯形两侧斜面与整体吊弦心形护环两内侧面密贴,所述凸台Ⅰ、凸台Ⅱ下部的半圆形凸台与整体吊弦吊环顶部之间具有一定间隙。本发明能有效防止心形护环底部吊弦线的磨损,保证线路安全运行。
