Comprehensive performance test and debugging test device and test method of rotary drilling rig

Abstract

The invention discloses a comprehensive performance test and debugging test device and test method of a rotary drilling rig. A dynamometer motor in the test device is arranged on a foundation; a torque transmission gear box is fixed on a gear box anchoring plate through a gear box adapter plate; a speed-up corner gear box is arranged on the torque transmission gear box, and is connected with the dynamometer motor through a transmission shaft, a torque sensor and a motor coupler in sequence; a driving sleeve is arranged in a connecting shaft of they torque transmission gear box, the lower end of a driving sleeve is connected with a hydraulic load oil cylinder through a slewing bearing I, a slewing support and a tension and pressure sensor, the slewing support is fixed in they foundation, and the hydraulic load oil cylinder is connected to a hydraulic station through a hydraulic pipeline; a tension and pressure sensor and a load oil cylinder pressure control valve in the hydraulic station are connected to a calculation software machine control system; the torque sensor is connected with a computer software control system; the dynamometer motor is connected in parallel with a distribution room power grid and a water-cooled resistance box. The control is more accurate, the actual working condition can be simulated, and the comprehensive data analysis capability is stronger.

Description

technical field [0001] The invention relates to the field of rotary drilling rigs, in particular to a comprehensive performance testing and debugging test device for rotary drilling rigs based on an electric dynamometer and feeder system. Background technique [0002] Rotary drilling rig is a kind of construction machine suitable for hole-forming operations in building foundation engineering. It is widely used in drilling construction in various stratum structures such as silt, clay, mud sand, gravel, silt pebbles, rocks, etc., and it is extremely difficult to meet the working conditions. complex. [0003] At present, there are two main methods for off-line commissioning of rotary drilling rigs: drilling commissioning and comprehensive test bench commissioning. Drilling and debugging need to occupy the ground space, and the torque value can only reach 20% of the design value, the debugging effect is not ideal, and it is impossible to measure whether the technical parameters...

AI Technical Summary

Problems solved by technology

However, the torque load is provided by the water eddy current dynamometer, the load is relatively stable, the loading speed is slow, and it cannot simulate the sudden change of load caused by the formation change in the actual working condition, and there is a certain gap between the provided debugging environment and the actual working condition
