The application discloses a rotary drilling rig multistage dynamic verticality control device, which comprises a high-precision inclinometer, a drill rod verticality real-time monitoring mechanism, a hydraulic adjusting sliding frame, a power head and a self-adaptive controller; four directionally arranged through holes are reserved in the drill rod, and one set of drill rod verticality real-time monitoring mechanism is arranged in each through hole. The self-adaptive controller is electrically connected with the drill rod verticality real-time monitoring mechanism, the high-precision inclinometer and the hydraulic adjusting sliding frame; the self-adaptive controller controls the hydraulic adjusting sliding frame to adjust the power head according to the inclination of the drill bit top plane measured by the high-precision inclinometer, so that the drill rod is coarsely leveled; the self-adaptive controller controls the hydraulic adjusting sliding frame to adjust the power head according to the inclination of the drill bit top plane measured by the high-precision inclinometer, so that the drill rod is coarsely leveled; and the self-adaptive controller controls the hydraulic adjusting sliding frame to adjust the power head according to the detection distance L and the initial detection distance L0, so that the drill rod is finely leveled.

This invention provides a differential-type continuously variable transmission (CVT) for automobiles. The transmission housing contains a differential, with a driven gear fixedly connected to the differential housing. A driving gear is fixedly connected to the power input shaft beside the differential, meshing with the driven gear. A generator is located on the left side of the transmission housing. The generator rotor shaft is connected to the shaft of the left sun gear of the differential and is equipped with a speed sensor. A torque detection device for detecting the forward and reverse torque of the generator rotor shaft is located at the junction of the transmission housing and the generator. The generator is also equipped with a generator brake. An electric motor is located on the right side of the transmission housing. The shaft of the right sun gear of the differential is connected to the rotor shaft of the electric motor and is equipped with a speed sensor. The electric motor rotor shaft serves as the power output shaft. This transmission is suitable for both hybrid electric vehicles and pure gasoline vehicles. The generator brake and differential work together to replace the function of a clutch, resulting in a simpler transmission system, the ability to withstand greater torque, and higher operational reliability.
