The utility model aims to provide a folding ladder stand which is used for being installed on a water tank and comprises a ladder main body and a folding assembly, the top end of the ladder main body is rotatably connected with the top of the water tank, the folding assembly comprises two long arms and two short arms, one ends of the two long arms are rotatably connected with the bottom end of the ladder main body, and the two long arms are located on the two sides of the ladder main body respectively. One ends of the two short arms are rotationally connected with the bottom of the water tank, the other ends of the two short arms are rotationally connected with the other ends of the two long arms respectively, and the length of the long arms is larger than that of the short arms; the minimum distance between one end of the short arm connected to the water tank and one end of the long arm connected to the ladder main body is equal to the length difference between the long arm and the short arm. Therefore, under the matching action of the ladder main body, the long arm and the short arm, the folding ladder stand can be folded so as to be convenient to transport, and space occupation is avoided when the folding ladder stand is not used.

The utility model discloses a wind pressure resistant door and window hinge, which belongs to the technical field of hinges, and comprises a bottom plate, a support arm, a long arm, a short arm and a reinforcing arm which are mutually hinged and matched, the bottom plate is provided with a bottom plate positioning part, the support arm is provided with a support arm first positioning part and a support arm second positioning part, and when the support arm is hinged and opened relative to the bottom plate, the long arm and the short arm are fixed. The short arm is positioned on the bottom plate positioning part and the first supporting arm positioning part, and the long arm is positioned on the second supporting arm positioning part. According to the door and window hinge, positioning stress during opening is achieved between the bottom plate and the supporting arm through the bottom plate positioning part, the first supporting arm positioning part and the second supporting arm positioning part, so that acting force generated after a door and a window are opened is effectively dispersed to all parts of the whole door and window hinge; therefore, the deformation resistance, the bearing capacity and the wind pressure resistance of the door and window hinge are improved, a series of problems such as shaking, vibration, even reset rotation or excessive opening of the door and window due to external force after the supporting arm is hinged and opened relative to the bottom plate are avoided, and the use safety of the door and window is ensured.

A large-angle rotation robot joint includes a thigh and a lower leg. The lower end of the thigh is hinged to the upper part of the lower leg to form a knee joint. A through hole at the upper end of the thigh serves as a hip joint. The lower leg is L-shaped, consisting of a long arm and a short arm. The hinge point between the lower leg and the thigh is at the junction of the long and short arms. A primary link is hinged to the thigh, and the other end of the primary link is hinged to a secondary link. The other end of the secondary link is hinged to the short arm of the lower leg. A hydraulic cylinder is hinged between the thigh and the primary link, with the hinge point between the hydraulic cylinder and the thigh located above the hinge point between the primary link and the thigh. This invention uses a four-bar linkage to meet the needs of large-angle rotation of the hydraulic cylinder-driven robot joint; it uses a double thigh arm design to facilitate component installation and avoid interference; and the left and right drive components are symmetrically arranged for balance.

This invention discloses a tilting and straightening device for large-tonnage components, relating to the field of component tilting technology. The device includes a frame, a first L-shaped hinged frame, a second L-shaped hinged frame, and a hydraulic cylinder. The short arms of the two hinged frames are nested and interlocked on the same horizontal plane. The device has a gravity-pneumatic linkage support system on the inner surfaces of the second short arm and the second long arm, and a mechanical locking mechanism between the two arms. The gravity-pneumatic linkage support system includes at least one first elastic pad, at least one second elastic pad, and a pneumatic circuit assembly connecting the two. The first elastic pad is vertically movable and protrudes from the surface of the second short arm, while the second elastic pad is vertically movable and flush with the surface of the second long arm in its natural state. When the component is pressed against the second short arm, the first elastic pad retracts, and gas pushes the second elastic pad to protrude and fill the gap between the side of the component and the long arm, preventing the component from sliding and colliding during tilting.
