The application discloses a carrying robot mechanical arm and a use method, and relates to the technical field of medical auxiliary devices.The mechanical arm comprises a multi-axis bending part, which has at least three degrees of freedom and is used for realizing pitching, yawing, lifting actions and bending shape adjustment along a tangent direction of a contact surface; and an end execution component, which is fixedly connected to a free end of the multi-axis bending part and is used for exploring under a patient's body and performing a lifting action.The multi-axis bending part has at least three degrees of freedom, and is combined with a bionic spine joint or a flexible continuum structure, so that the mechanical arm can realize active bending shape adjustment along the tangent direction of the contact surface during the exploration under the patient's body and the lifting process, stress concentration caused by a pose error of a traditional rigid mechanical arm on a local part of the patient's body is effectively avoided, and the risk of secondary injury in a spinal column injury or postoperative patient transfer process is significantly reduced.

This invention relates to the field of automotive power steering pump technology, specifically to a dual-source electric power steering pump switching control system and its power steering pump. The system includes a motor housing and a stator winding fixed inside and within the motor housing. The stator winding consists of a high-voltage winding and a low-voltage winding, which operate independently. When the vehicle's high-voltage power supply fails, the stator winding switches from high-voltage to low-voltage operation. This dual-source electric power steering pump switching control system, combined with the single-motor, dual-winding design of the dual-source electric power steering pump, enables switching to the low-voltage winding when the vehicle's high-voltage power supply fails. This drives the power steering pump to provide degraded but safe power steering assistance, achieving a "limp-home" function, preventing the vehicle's steering wheel from completely losing power assist, facilitating parking, and improving safety redundancy.

The invention relates to Chinese art paper manufacturing, in particular to a curtain grain conveying belt, a belt body of the conveying belt comprises a curtain grain belt used for filtering paper pulp and intercepting paper fibers, the curtain grain belt is formed by weaving plastic bamboos and braided ropes in a criss-cross mode, and the belt body of the conveying belt further comprises a base mesh belt with the belt face arranged in a porous mode.

The conveying belt is formed by combining a base mesh belt and a curtain stripe belt, on the basis that the curtain stripe belt can form a wet paper sheet with curtain stripes, the base mesh belt serves as a framework layer and can provide enough supporting strength for the curtain stripe belt, and the problems that the curtain stripe belt is pressed when bearing paper pulp and is prone to bending deformation, and gaps of thin bamboo strips on a belt body are enlarged are effectively solved; and a more reliable quality guarantee is provided for subsequently formed paper products.

The application relates to the field of building construction, in particular to an embedded overhead heat-preservation and sound-isolation integrated floor system, which comprises a prefabricated floor with a thickness of 5-10 cm, an overhead heat-preservation layer with a thickness of 2-4 cm arranged above the prefabricated floor; an array of reserved holes is arranged on the heat-preservation layer, and the spacing between adjacent reserved holes is 20-60 cm; sound-isolation support columns are arranged in the reserved holes; the sound-isolation support columns are arranged in an array on the heat-preservation layer; cast-in-situ concrete is arranged above the heat-preservation layer; an overhead floor is arranged above the cast-in-situ concrete through the array of sound-isolation support columns; and a cavity layer is formed between the overhead floor and the cast-in-situ concrete. The application can improve the sound-isolation performance and heat-preservation performance of the prefabricated laminated floor.

This invention discloses a basket frame with a lower left frame rotatably connected to the left side of the middle frame and a lower right frame rotatably connected to the right side. The upper end of a left linkage rod is rotatably connected to the upper left frame, and the lower end is rotatably connected to the left side of the middle frame. The upper end of a right linkage rod is rotatably connected to the upper right frame, and the lower end is rotatably connected to the right side of the middle frame. A left sliding sleeve is provided on the left linkage rod, and a first left connecting rod is provided between the left sliding sleeve and the lower left frame. A second left connecting rod is provided between the left sliding sleeve and the right linkage rod. A right sliding sleeve is provided on the right linkage rod, and a first right connecting rod is provided between the right sliding sleeve and the lower right frame. A second right connecting rod is also provided between the right sliding sleeve and the left linkage rod. When the upper left and upper right frames rotate relative to each other at their connection point and move closer to the middle frame, the lower left and lower right frames rotate and move closer to the middle frame. This invention also discloses an infant carrier using the aforementioned basket frame. This invention is easy to fold, has strong load-bearing capacity, and has a small folded size.

The utility model discloses a quadruped robot wheel foot cover tire, which is in a circular ring shape and comprises a mounting area, a tire cover and a tire cover, and is characterized in that the mounting area is used for connecting a quadruped robot wheel hub; the buffer area is provided with a hollow part, and the hollow part extends inwards from the outer side face in the width direction of the outer tire; the action area can be in contact with the ground, and anti-skid ribs are formed in a circle in the circumferential direction; the mounting area, the buffer area and the action area are sequentially arranged outwards in the radial direction from the center of the outer tire and are concentric and coaxial. The utility model further discloses a quadruped robot wheel foot. Due to the arrangement of the hollow parts in the buffer area, the weight of the outer tire is reduced, vibration generated by the outer tire can be effectively absorbed, and the movement stability of the quadruped robot is high due to the overall structure; the mounting area, the buffering area and the acting area are sequentially and concentrically arranged from inside to outside, the stability of the hub in the circumferential direction in the movement process is guaranteed, and deviation and even slipping are avoided.
