This invention relates to the field of humanoid robot technology and discloses a humanoid robot torso waist rotation linkage adjustment device, including a torso lower mounting plate, a central rotation axis, an intermediate connecting bracket, a left hip connecting seat, and a right hip connecting seat. The torso lower mounting plate is horizontally disposed at the bottom of the robot torso. The central rotation axis is arranged vertically and its upper end is coaxially fixedly connected to the lower surface of the torso lower mounting plate. The intermediate connecting bracket is fitted into the middle of the central rotation axis and rotatably connected to the central rotation axis. The left hip connecting seat and the right hip connecting seat are symmetrically arranged on both sides of the lower end of the intermediate connecting bracket. This invention achieves synchronous adjustment of torso waist rotation and lower limb posture through a mechanical linkage structure, which can adjust the lower limb posture in time during waist rotation, effectively counteract the center of gravity shift caused by torso rotation, and improve the robot's balance stability in dynamic motion scenarios.

This utility model provides a foldable flue transport vehicle, relating to the field of construction technology. It includes a support frame, inside which are arranged a set of solid shafts (set one and set two). Limiting plates are respectively installed on one side of each of the solid shafts. A reinforcing bar connecting ring is fitted onto the solid shaft, with a seamless steel pipe welded to one end of the first connecting ring. Similarly, a reinforcing bar connecting ring is fitted onto the solid shaft, with a seamless steel pipe welded to one end of the second connecting ring. After use, gently pushing the load-bearing horizontal plate inward causes the reinforcing bar connecting rings to deform as the frame rotates, bringing the two frames closer together to achieve a folded state. After folding, the volume is reduced to 1 / 3 to 1 / 2 of the original volume, facilitating on-site transport and storage.

This utility model relates to the field of fiber fabric processing technology, specifically to a fabric flipping device for fiber fabric processing. It includes a processing table and two sets of flipping connection units. Each flipping connection unit includes a bracket, a right-angle plate, a U-shaped frame, a slide rod, a spring, a lower pressure plate, an adjusting bolt, a rotating assembly, and a support assembly. In use, the U-shaped frame is pushed upwards to open the space between the lower pressure plate and the right-angle plate. Then, the air conditioning fiber is spread out and placed between them. Releasing the U-shaped frame causes the lower pressure plate to contact the air conditioning fiber due to gravity. At this point, the spring compression provides elastic cushioning, preventing rigid compression from damaging the air conditioning fiber. Simultaneously, the clamping force of the lower pressure plate can be finely adjusted by adjusting the depth of the adjusting bolt's screw into the threaded hole. This method secures the air conditioning fiber, preventing it from falling to the ground during flipping, reducing the number of times workers need to clean it, and ensuring processing efficiency and quality.

The application discloses a hoisting equipment for steel box girder bridge construction and relates to the technical field of hoisting equipment, which comprises a machine body, a positioning device and a stabilizing device. The machine body comprises a connecting seat and a movable seat. The positioning device comprises four positioning components. The positioning component comprises a positioning structure, a first rope, a first winding roller and a first driving piece. The stabilizing device comprises two stabilizing components. The stabilizing component comprises a stabilizing piece, a second rope, a second winding roller and a second driving piece. A first locking pin is arranged on the movable seat, and a first locking groove is formed in the first winding roller. A second locking pin is arranged on the connecting seat, and a second locking groove is formed in the second winding roller. The application can effectively protect the driving piece during the hoisting of the steel box girder, reduce the probability of safety accidents caused by the imbalance of the steel box girder due to the failure of the driving piece, and realize the stable placement of the hoisting equipment without the need of workers to bear risks and assist in the stable placement.

The utility model discloses an impeller and a fan, and relates to the technical field of impeller machinery, the impeller comprises a main body and a top cover; the top cover is connected with the main body, the top cover is provided with a plurality of balance ribs, and the plurality of balance ribs are uniformly arranged on the surface of the top cover. According to the technical scheme, the balance stability of the impeller can be improved.

The utility model discloses an adjustable hanging fence safe operation platform, including operation platform, adjustable derrick and top truss, operation platform includes platform steel sheet and platform fence, and the bottom of platform fence is connected with the edge position of platform steel sheet, adjustable derrick includes channel steel, I -beam and adjusting bolt, and I -beam is movably arranged in channel steel, channel steel and I -beam are connected through adjusting bolt that sets up in adjusting screw hole respectively and is set up adjusting screw hole respectively, and the bottom of adjustable derrick is connected with platform fence, and top truss is connected with the top of adjustable derrick, and it does not need the complex system of electrical control elevator, steel wire rope, safety lock and the like, and it is beneficial to the stress concentration of hanging fence safe operation platform in multidirectional direction to be conducted to pier body side and pier top, thereby avoiding the complex counterweight problem of traditional hanging basket and the risk of unbalanced overturning, and improving safety and stability.

The application discloses a complete iron accessory of a power distribution transformer substation, relates to the technical field of iron accessory installation, and comprises a limiting rod, clamping seats are symmetrically and slidingly installed outside the limiting rod, a rail seat is installed at the outer curved bottom of the clamping seat, a stand column is installed at the top of the rail seat, a supporting rod is slidingly installed by being embedded into the bottom end of the stand column, a pressing plate and a guide block are respectively installed at the two ends of the supporting rod, and a rail rod is embeddedly installed at the end of the rail seat corresponding to the position of the guide block. The application can realize triple utilization of self gravity, non-Newtonian fluid gravity and cable gravity, can convert and absorb external wind disturbance, collision and beating force and ground vibration force suffered by erected rod frames, effectively combines the reliability of hard support and the flexibility of flexible limiting, realizes displacement compensation of the internal structure of the iron accessory and relative sliding between the erected rod frames, can effectively absorb vibration interference, avoids loosening and sliding of the iron accessory, indirectly realizes noise reduction, and improves the compatibility of the iron accessory.
