Overall test and data testing device for large-tonnage horizontal directional drilling machine

Abstract

The invention discloses an overall test and data testing device for a large-tonnage horizontal directional drilling machine. The overall test and data testing device comprises a basic connecting plate, a power input connector, a carriage, a dynamometer, a computer torsion control circuit, a computer torsion control operating table, a computer push-pull force control operating table, a computer push-pull force control circuit, a push-pull force sensor and a hydraulic damping system. The hydraulic damping system is composed of a damping oil cylinder, a hydraulic pipeline and a hydraulic station. The torque, the rotating speed and the power of the dynamometer are connected to the computer torsion control operating table through the computer torsion control circuit, and signals of the push-pull force sensor of the hydraulic damping system are input in the computer push-pull force control operating table through the computer push-pull force control circuit. After power is input in the overall test and data testing device for the large-tonnage horizontal directional drilling machine by the horizontal directional drilling machine, overall tests and testing can be conducted on push force and pull force of the horizontal directional drilling machine and the output torque, the rotating speed and the power of a power head of the horizontal directional drilling machine.

Description

Technical field [0001] The invention relates to a complete machine test equipment for a horizontal directional drilling rig, in particular to a complete machine test and data testing device for a large-tonnage horizontal directional drilling rig. Background technique [0002] The horizontal directional drilling rig is a construction machine that lays a variety of underground utilities (pipes, cables, etc.) without excavating the ground surface. It is widely used in the laying of pipelines for water supply, electricity, telecommunications, natural gas, gas, and oil. During construction, it is suitable for sand, clay, pebbles and other ground conditions. It can be constructed in most non-hard rock areas in my country. [0003] At present, after the large-tonnage horizontal directional drilling rig has been installed on the assembly line, there are not enough detection methods for the design technical parameters to meet the needs. The technical parameters can only be detected by actual...

Problems solved by technology

[0003] At present, after the large-tonnage horizontal directional drilling rig is off the assembly line, there are not enough detection methods for the design technical parameters to meet the needs. Only when it is empty or on the ground is the actual drilling to detect the technical parameters. Problem: The technical indicators measured at no-load are inaccurate; the ground of the test site is a limited resource, and it is impossible to use it repeatedly for a long time
