The utility mode relates to a stock anchor rope installation boost motor, the problem that the degree of difficulty is big, the low just construction quality of efficiency of construction can not get effective assurance is installed in the existence when having solved the anchor of stock anchor rope extension. Including stock anchor rope body and roofbolter, the bottom cover of stock anchor rope body has stock anchor rope erector, stock anchor rope erector sub -unit connection has the boosting output shaft, the bottom mounting of boosting output shaft has from the driving wheel, roofbolter's top is fixed with the action wheel, be provided with the transfer line between roofbolter and the stock anchor rope body, the upper end of transfer line is provided with the last drive gear who meshes with the action wheel, the transfer line lower extreme is provided with and follows the lower drive gear that the driving wheel meshed, and the direction snap ring that the cover has with roofbolter is fixed on the transfer line. The utility model discloses shorten or cancelled the distance of artifical propulsion stock anchor rope, reduced the extra long anchored installation degree of difficulty, reduced field force's intensity of labour moreover, guaranteed construction quality's reliable performance simultaneously.
