Wrap angle adjustable tension measuring device for hoisting rope

The invention relates to a wrap angle adjustable tension measuring device for a hoisting rope. The wrap angle adjustable tension measuring device comprises a support, wherein a head sheave for a to-be-measured hoisting rope to bypass is arranged at the top of an upright post of the support; a locating seat for being connected with the first end of the to-be-measured hoisting rope is arranged on the support; a hoist drum for applying traction acting force to the second end of the to-be-measured hoisting rope is also arranged on the support; the support is also provided with reverse wheels capable of moving towards the left side and the right side. Actual use conditions of the hoisting rope are simulated by using the hoist drum, the upright post, the head sheave and the locating seat; wrap angles formed by the to-be-measured hoisting rope and two leads of the head sheave can be adjusted by changing the positions of the reverse wheels so as to adapt to different testing conditions; during measurement, the tensio
