Exercise device
The invention provides a motion device. The motion device comprises a base, a first linear motor, a second linear motor, a first flexible assembly, a second flexible assembly and a middle beam structure. The base has a surface extending in an x-direction and in a y-direction, a z-direction perpendicular to the base surface. The first and second linear motors are mounted on the surface of the base parallel to the x direction. The first end of the middle beam structure is connected with the first linear motor rotor through a first flexible part, and the second end of the middle beam structure is connected with the second linear motor rotor through a second flexible part. The first flexible member has Rz-direction flexibility, rigidity for suppressing movement in the x-direction, rigidity for suppressing movement in the z-direction, rigidity for suppressing movement in the Rx-direction, and rigidity for suppressing movement in the Ry-direction. The second flexible part has Rz-direction flexibility, y-direction flexibility, rigidity for restraining movement in the x-direction, rigidity for restraining movement in the z-direction and rigidity for restraining movement in the Ry-direction.

Counterweight guide rail bracket for guiding elevator direction
The invention relates to the technical field of supports, and discloses an elevator direction guide counterweight guide rail bracket which comprises a counterweight housing, a guide part mounted on the counterweight housing and used for providing accurate guide compensation for a counterweight and ensuring stable operation of an elevator, and a cooperative part mounted on the guide part and used for cooperative work and guide linkage of the guide part. By adopting the structure formed by the cross beam, the U-shaped frame, the L-shaped arm, the buffer pad, the spring and the like of the buffer part, when an elevator breaks down, collision impact of a counterweight can be effectively buffered, when the counterweight frame rushes to the top, the L-shaped arm extending out of the upper portion makes contact with a ceiling preferentially and slides along the inner wall of the U-shaped frame through extrusion, meanwhile, the spring is stretched for buffering, and the service life of the counterweight frame is prolonged. The L-shaped arm is inserted between the two gears to be meshed, the gears are driven to rotate in the opposite direction, the counterweight frame rebounds and resets by a certain distance along the guide rail, and the situation that the counterweight frame directly collides with a ceiling to cause scrapping and huge safety risks is avoided.
