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.
本发明公开了一种用于钻井吊车的钢丝绳夹紧装置,涉及石油行业钻修井设备技术领域。本发明包括底座、调节组件、紧固组件、导向轮和分别套设在底座四角的地锚组件,调节组件固定安装在底座上表面;调节组件包括固定安装在底座上表面绕线盘;绕线盘一侧面固定安装有绕线把手;底座上表面且位于调节组件一侧固定安装有紧固组件;底座上表面且位于紧固组件远离调节组件一侧固定安装有导向轮。本发明通过调节组件对绷绳长度进行调节后紧固组件中的直角梯形结构的主钳块与副钳块的相互配合可以使得弧形结构的制动片能够稳固的加紧绷绳,结构简单,能确保主副钳两侧间隙均匀,同时时能使绷绳有效加紧在固定组件内上,提高了井架的稳定性。
