The invention provides a portable rope clamping and loosening device. The portable rope clamping and loosening device comprises a supporting frame and a rope clamping device, wherein one end of the supporting frame is fixed, one side of the suspending end of the supporting frame is provided with a wedge-shaped base, one end of the rope clamping device is inserted in the wedge-shaped base, and therope clamping device comprises two wedge-shaped blocks which are symmetrically arranged. A gap is formed between the two wedge-shaped blocks, the front view of the wedge-shaped blocks is in a shape ofa right-angled trapezoid, the short edges of the wedge-shaped blocks are inserted in the wedge-shaped base, the long sides of the wedge-shaped blocks protrude on the supporting frame, the slant edgesof the wedge-shaped blocks fit the wedge-shaped base, semicircular grooves matched with a rope are formed in the right-angled sides of the wedge-shaped blocks, and are opposite to each other, the wedge-shaped base is matched with the two spliced wedge-shaped blocks in shape, and the bottom face of the wedge-shaped base is larger than the bottom face of the two spliced wedge-shaped blocks. By means of the portable rope clamping and loosening device, rope clamping, rope lifting, and rope loosening at a limited speed are conducted, and on-spot detection of an elevator speed limiter is achieved.The portable rope clamping and loosening device is simple in overall structure, convenient to operate and capable of being applicable to a narrow space without a machine room. Moreover, there is no need to detach the elevator speed limiter for detection, the working efficiency is improved, the detection time is shortened, and the maintenance cost is reduced.

    本发明提供一种便携式夹绳松绳装置,包括支撑架和夹绳器,所述的支撑架的一端固定,支撑架的悬空端一侧设有楔型座,所述的夹绳器一端插入到楔型座内,所述的夹绳器包括相互对称设置的两块楔形块,两块楔形块之间设有间隙,所述的楔形块的正视图成直角梯形,楔形块的短边插入到楔型座内,楔形块的长边突出于支撑架之上,楔形块的斜边与楔型座贴合,楔形块的直角边上设有与绳索匹配的半圆弧凹槽,两块楔形块的半圆弧凹槽相向设置,楔型座的形状与两块拼合后的楔形块的形状相匹配,楔型座的底面大于两块拼合后的楔形块的底面。通过该装置来进行夹绳、提绳、限速度松绳操作,进行电梯限速器的现场检测,其整体结构简单,操作方便,能够适用于无机房内的狭小的空间,且不需要将电梯限速器拆下来进行检测,提高了工作效率,缩短了检测时间,且节约了维护成本。
