[0002] In many large-scale engineering constructions, it is necessary to carry large-tonnage equipment (facilities) on slopes or in inclined tunnels. Due to terrain conditions or space limitations, it is impossible to directly use transport vehicles for transportation. Instead, a winch (or hoist) is used in combination with a steel wire rope or a lifting pulley and a guiding pulley (guide wheel) for pulling and hauling. Among them, when using a guiding pulley (guide wheel), a standardized product is generally selected according to the magnitude of the traction force and the diameter of the traction steel wire rope. Since the weight of the equipment (facilities) to be transported in large-scale projects is often large, the size and weight of the selected guiding pulley are large, which is not only inconvenient for on-site installation and use, but also difficult to purchase and expensive.

There are two radially symmetrical grooves 15 adapted to the clamping plate 14 on the outside of the sleeve 5, the through hole 22 penetrates through the groove 15, a tapered rod 18 is abutted between the two push plates 16, a guide rod 13 is concentrically fixed at the end of the tapered rod 18 and axially slidably connected inside the sleeve 5, two mirror-symmetrical guide grooves 4 are axially opened on the inner wall of the sleeve 5, a guide block 12 is slidably connected in each guide groove 4, the guide block 12 is fixedly connected to the guide rod 13, the end of the sleeve 5 is movably connected to a limiting block 2, an external thread 6 is opened at one end of the sleeve 5, a thread groove 3 adapted to the external thread 6 is opened on the inner side of the limiting block 2, the limiting block 2 is threadedly sleeved on the end of the sleeve 5 and abuts against the outside of the support plate 1, and the limiting block 2 is hexagonal.
