The invention discloses a steel
wire rope clamping device for a drilling crane, and relates to the technical field of drilling and
workover equipment in the
petroleum industry. The steel
wire rope clamping device comprises a base, an adjusting
assembly, a fastening
assembly, a guide wheel and ground anchor assemblies arranged at the four corners of the base in a sleeving mode; the adjusting
assembly is fixedly installed on the upper surface of the base; the adjusting assembly comprises a wire spool fixedly installed on the upper surface of the base; a wire winding
handle is fixedly installed on one side surface of the wire spool; the fastening assembly is fixedly installed on the upper surface of the base and located on one side of the adjusting assembly; and the guide wheel is fixedly installed on the upper surface of the base and located on the side, away from the adjusting assembly, of the fastening assembly. According to the steel
wire rope clamping device for the drilling crane, after the length of a guy
rope is adjusted through the adjusting assembly, a main clamp block and an auxiliary clamp block of a
right trapezoid structure in the fastening assembly are matched with eachother, so that a
brake pad of an arc-shaped structure can stably tighten the guy
rope, the structure is simple, it can be guaranteed that gaps between the two sides of a main clamp and the two sidesof an auxiliary clamp are uniform, meanwhile the guy
rope can be effectively tightened in the fixing assembly, and the stability of a derrick is improved.
