The utility model discloses a horizontal oil cylinder dismounting machine, which relates to the technical field of horizontal oil cylinder dismounting and comprises a frame and an oil cylinder body, the oil cylinder body is fixedly connected with the inside of the frame, a piston rod is slidably mounted in the oil cylinder body, and one end of the piston rod extends out of the inside of the oil cylinder body. A controller is fixedly installed on the top of the rack, a fixing frame is fixedly connected to one end of the rack, a lead screw is rotationally connected into the fixing frame, a motor is fixedly installed at one end of the fixing frame, an output shaft of the motor is fixedly connected with one end of the lead screw, and a movable frame is installed on the outer surface of the lead screw in a threaded mode. The other end of the movable frame is provided with a limiting part for limiting the rotating speed of the lead screw. According to the oil cylinder, the lead screw is matched with the movable frame, the motor is used for driving the two-way screw rod to rotate according to needs, the contact area of the two-way screw rod and the protruding block is adjusted, then the rotating speed of the lead screw is limited, and therefore the speed that the piston rod rushes out of the oil cylinder body is reduced to a certain degree.

The present application belongs to the technical field of lower limb training robot, and specifically discloses a robot lower limb training method, comprising the following steps: step 1, fitting a hip joint rotation angle change curve, a center of gravity up and down position change curve and a center of gravity forward speed change curve according to gait information of a human body; step 2, using a gravity compensation PD control algorithm to control rotation of an exoskeleton motor according to the hip joint rotation angle change curve; using a PD control algorithm with weight reduction bias to control rotation of a lifting motor according to the center of gravity up and down position change curve; and using a PI control algorithm to control rotation of a bottom wheel according to the center of gravity forward speed change curve; the present application provides a robot and a lower limb training method capable of improving human-computer interaction compliance.

The utility model relates to a steel wire forcing device which comprises a fixing support, a guide wheel set, a brake disc, brake calipers and a controller, a cavity is arranged in the fixing support, the guide wheel set is arranged in the cavity and comprises at least two guide wheels, the guide wheels are in running fit with the fixing support, the brake disc is installed on a rotating shaft of the guide wheels, and the brake calipers are arranged on the brake disc. The brake caliper is installed on the fixing support and matched with the brake disc, the controller is arranged on the fixing support, and the brake caliper is electrically connected with the controller. According to the steel wire forcing device, in the steel wire guiding process, firstly, a steel wire is guided into the guide wheel set and wound on the guide wheels, the steel wire inlet and the steel wire outlet are formed in the fixing support, when the steel wire is not wound tightly, the brake calipers are controlled to brake, the rotating speed of the guide wheels is reduced, and then the output speed of the steel wire is reduced; the steel wire winding speed is larger than or equal to the steel wire output speed, and finally steel wire winding is tighter.

The utility model discloses a height adjusting device for automobile detection platform relates to automobile detection platform technical field. The height adjusting device for automobile detection platform includes the mount, the upper portion of mount is provided with adjusting mechanism: drive assembly, including fixed mounting on the upper portion of mount and is increased height frame, the upper portion fixed mounting of height frame has the shell, the upper end fixed mounting of shell has the top, the upper portion fixed mounting of top has drive motor, rotates through drive motor and drives gear, and two groups of planetary gears are under the double restraint of the tooth profile structure of shell inner wall and drive gear, transmission frame bottom gear -like convex, revolve around drive gear, and also carry out autogyration, realize deceleration and increase the moment, and the tooth profile convex of transmission frame bottom and the planetary gear of output frame upper portion secondary reduce output speed and improve output torque, so that drive motor can select low output torque's model, thereby reduce the volume of drive motor, avoid the device volume too big.
