4results about How to "Large lifting stroke" patented technology

The invention discloses an X-ray photography system and a detection bed thereof, the detection bed comprises a base, a lifting support, a gravity balance part and an electric driving part, the gravity balance part provides upward self-adaptive supporting force for the lifting support, and the self-adaptive supporting force is used for balancing and offsetting the gravity borne by the lifting support; the electric driving part is used for electrically driving the upper end of the lifting support to lift relative to the lower end so as to drive the bearing platform to lift. Due to the fact that the detection bed is provided with the gravity balance part and the electric driving part, the gravity balance part can provide supporting force matched with the gravity balance part according to the gravity borne by the lifting support, and stable hovering of the bearing platform can be achieved no matter whether a patient exists on the bearing platform or not; on the basis of gravity balance of the gravity balance part, the electric driving part only needs to output small thrust or pulling force to drive the bearing platform to electrically ascend and descend, rapid ascending and descending driving of the detection bed can be achieved, and meanwhile the ascending and descending stroke of the detection bed can be increased.

This invention discloses a lifting worktable, including a work platform, a base, a locking mechanism, and a lifting assembly. The lifting assembly includes at least one set of lifting arms, each set of lifting arms including at least two support arms hinged in the middle in an X-shape: a first support arm and a second support arm. The lifting assembly also includes a first rotating bracket and a second rotating bracket. The first rotating bracket includes two first rotating arms and two first traction arms that simultaneously fold towards the center or simultaneously unfold to both sides, with the two first traction arms respectively connected to the two first rotating arms. The second rotating bracket includes two second rotating arms and two second traction arms that simultaneously fold towards the center or simultaneously unfold to both sides, with the two second traction arms respectively connected to the two second rotating arms. When the lifting worktable is raised or lowered, the center of gravity of the supporting lifting arm remains relatively unchanged with respect to the center of gravity of the load on the work platform, avoiding tipping over, providing good support stability, and having a large lifting stroke, allowing it to be used on the ground.

The utility model discloses a solar energy compression peel box, and the peel box body is provided with a solar power generation device, the solar power generation device comprises a solar panel, a solar charging controller and a battery, the solar panel is installed on the top of the outer side of the peel box body, the solar panel is connected with the solar charging controller, the solar charging controller is connected with the battery, and a compression device is further installed in the peel box body, the compression device comprises a driving motor, a scissors lifting frame structure and a compression plate, the driving motor can drive the scissors lifting frame structure to lift, the compression plate can enter and exit the garbage can, and the garbage in the garbage can can be compressed.
