Steel wire rope clamping device for drilling crane

Abstract

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.

Description

technical field [0001] The invention belongs to the technical field of drilling and workover equipment in the petroleum industry, in particular to a wire rope clamping device for a drilling crane. Background technique [0002] After the oil drilling and well workover operation equipment is hoisted on the construction site, the ground fastening operation of the windproof guy rope of the derrick must be carried out. In order to meet the requirements of windproof management, the derrick guy rope must be installed. The guy rope is an important support for the operation derrick to bear the tension and prevent the derrick from tipping over. Generally, four to eight steel wire ropes are used. The platform on the second floor is fixed on the ground at a certain angle with the ground surface. [0003] In the process of realizing the present invention, the inventor found that there are at least the following problems in the prior art: the upper end of the stay rope is connected to th...

Problems solved by technology

[0004] The object of the present invention is to provide a wire rope clamping device for a drilling crane. Through the mutual cooperation of the right-angled trapezoidal structure of the main tong block and the auxiliary tong block, the arc-shaped brake pads can firmly tighten the stay rope. Solve the problem that the existing stay rope is difficult to fasten after adjustment
