A comprehensive performance testing and debugging test device and test method of a rotary drilling rig

Abstract

A test device and test method for comprehensive performance testing and debugging of a rotary drilling rig. The dynamometer motor in the test device is set on the foundation; the torsion transmission gearbox is fixed on the gearbox anchor plate through the gearbox adapter plate; The gearbox is installed on the torque transmission gearbox, and the speed-increasing angle gearbox is connected with the dynamometer motor through the transmission shaft, torque sensor and motor coupling in turn; the drive sleeve is inserted into the connecting shaft of the torque transmission gearbox, and the lower end of the drive sleeve is passed through Support Ⅰ, slewing support, tension pressure sensor are connected with the hydraulic load cylinder, the slewing support is fixed in the foundation, and the hydraulic load cylinder is connected to the hydraulic station through the hydraulic pipeline; among them, the tension pressure sensor and the pressure control valve of the load cylinder in the hydraulic station Connected to the computer software control system; the torque sensor is connected to the computer software control system; the dynamometer motor is connected in parallel with the power distribution room power grid and the water-cooled resistance box. The invention has more precise control, can simulate actual working conditions and has stronger comprehensive data analysis ability.

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
