The invention discloses an integrated sealed contact group for railway, comprising a bottom shell, an upper shell, a central swing body, a static point unit, a moving contact, a drive block, an insulating protective cover and a terminal. The integrated sealed contact group for railway is a sealed and insulated integrated contact unit, the original installation and external dimensions are almost unchanged, and it can be completely interchangeable with existing contacts, the function is greatly upgraded, and no adjustment is required during installation and use, which is simple and fast; electrical contact redundancy technology, reciprocating linear motion technology, concave-convex nested physical isolation technology, integrated sealing technology and interchangeability technology are adopted; optical axis, bearing and rolling technology are adopted in many places, so that the contact group has low wear during use, flexible movement and rotation, no card group, reliable electrical action, long life, no trouble, and maintenance-free, and has met the highest requirements of the railway company for the contact group after various tests, and the electrical performance is reliable, stable and safe.

The invention relates to an integrated redundant contact group for a railway switch machine, comprising a static point combination, a moving point combination and a moving contact linear motion mechanism, etc.; three units, two static contact groups and one moving contact group, which are traditionally used in a dispersed manner, are designed to be a new integrated contact unit; the contact switch combination maintains the traditional left and right unit structure, but the plates and rings of the traditional contact group are rotated 90 degrees from the vertical direction to the horizontal direction, and are designed as upper and lower spring plates with the same potential and a moving point wheel at both ends, and a group of contact points are added to form an electrical contact redundant structure, and the upper plate or lower plate on any side can be connected to any upper and lower contact plate on the other side through the moving contact for electrical conduction; three paths are maintained on the left and right, and the moving point combination is the same, and the traditional three moving point rings are changed to six roller contacts, and a new moving point linear reciprocating motion mechanism is adopted to form an either-or electrical interlocking relationship, and the middle position is not in contact, so that an equivalent interlocking relationship is achieved.

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.
