Abstract

The invention discloses a large torque and super-large torque test system for engineering equipment. The large torque and super-large torque test system for the engineering equipment comprises a friction disk, friction sheets and a dynamometry disk, wherein the friction disk is fixedly provided with a fixed part connected with a drill pipe; the dynamometry disk and the friction disk are coaxially installed and are not directly contacted; the friction disk is driven by the drill pipe connected with the fixed part to rotate; the dynamometry disk independently rotates; the dynamometry disk is provided with at least one pressure device to press the friction disk and the dynamometry disk; the friction sheets are respectively installed between the friction disk and the dynamometry disk as well as between the pressure device and the friction disk; the dynamometry disk is provided with at least one dynamometry disk extending end; and the dynamometry disk extending end is arranged in a dynamometry device and is connected with the dynamometry end of the dynamometry device via a fixed point transmission ball. According to the large torque and super-large torque test system for the engineering equipment, which is disclosed by the invention, the maximum value of the static torque can be directly tested, and the dynamic torque value can be directly tested, thereby being favorable for debugging a product system parameter, a predelivery test and design evaluation.

Description

technical field [0001] The invention relates to a large torque and super large torque testing system for engineering equipment. Background technique [0002] At present, the output torque of the power head of large and super-large engineering equipment (such as rotary drilling rig) is very large (up to 400kN. Refer to GB21582-2008, through the indirect test of power head pressure, flow rate and output shaft speed, and then use the formula T=P*Q*η / (6.28*n 0 ) to calculate the torque. This is an approximate test method, the cumulative error is large, and when n 0 When it is zero, the maximum value of the static torque cannot be calculated, and other test methods need to be reconsidered, which brings great troubles to product design and development, product factory debugging and product application. Contents of the invention [0003] The purpose of the present invention is to provide an engineering equipment with high torque and super large torque which can not only direct...
