This utility model relates to the field of rehabilitation training medical device technology, specifically to a correction device for the sliding track of an H-rail transfer machine. The correction device has at least one component mounted on the sliding track, dividing it into at least two segments. Each correction device includes a fixed unit and a moving unit. The fixed unit is fixedly connected to the left side of the sliding track segment, and the moving unit is fixedly connected to the right side of the sliding track segment. The moving unit can move left and right relative to the fixed unit, allowing the length of the sliding track to extend or retract. The correction device in this utility model allows for a certain degree of extension or retraction of the sliding track, thereby preventing jamming caused by non-parallelism when the sliding track reaches the H-shaped track joint.

The invention discloses a granular gel-based living body material as well as a preparation method and application thereof. The particle gel-based living body material comprises hydrogel particles, sulfydryl-modified sulfate group-containing macromolecules and platelet-rich plasma dispersion liquid, and the particle gel-based living body material is of a cross-linked structure; photosynthetic oxygen production microorganisms are wrapped in the hydrogel particles. The hydrogel particles are prepared from branched macromolecules with double bonds and modified natural macromolecules through Michael addition polymerization, and the modified natural macromolecules are amino or sulfydryl modified natural macromolecules. The living body material is high in biological safety and stability, controllable release of the growth factors can be achieved, burst release and overhigh local concentration of the growth factors are prevented, and therefore the bioavailability of the growth factors is improved, and the lasting period of the growth factors is prolonged.

This utility model discloses a feeding mechanism and an extruder, belonging to the field of extruder technology. The feeding mechanism includes a first outer shell containing a feeding valve. The feeding valve is driven to rotate by a first motor and connected to a cover plate. The cover plate is displaced by a cylinder to drive the feeding valve in conjunction. The feeding valve encloses a feeding space, within which a scraper is installed. The scraper moves synchronously within the feeding space as the feeding valve rotates. The extruder includes a storage mechanism and an extrusion mechanism, both connected to the material cavity of the first outer shell. The storage mechanism includes a material box and a stirring section, while the extrusion mechanism includes a second outer shell and an extrusion auger. This utility model effectively avoids material jamming and clogging problems by using a scraper to clean residual material in the feeding space in real time, ensuring continuous and stable operation of the equipment.

This invention relates to a port data sharing method based on intelligent scheduling, applicable to data demander systems, data provider systems, and data sharing platforms. The demander submits a sharing ticket, which the platform sends to the provider. The provider returns a commitment result based on pruning rules: when the sharing policy corresponding to the purpose identifier is "only allow judgment" or "prohibit judgment," only the judgment result field is delivered; when the time limit requirement exceeds the committable range, the committable time limit and delivery window are returned; when the range identifier meets the splitting conditions, sub-tickets are obtained and delivery fields and delivery windows are determined separately; the provider forms a delivery package; the demander initiates a delivery request within the validity period calculated from the time the delivery package is published; the platform verifies the request and delivers it; if the time limit is exceeded or the scope is crossed, the request is rejected and a new ticket is required; the demander sends back the signature information, and the platform updates the subsequent ticket scheduling parameters accordingly, lowering the priority of tickets without signatures and restricting delivery methods.

The utility model relates to the field of oil and natural gas drilling technology, especially relate to a walking device for oil drilling iron roughneck. Walking device includes walking frame, drive mechanism and walking mechanism, can install iron roughneck on walking frame, and iron roughneck is installed in the front end of walking frame through connecting piece. Through the rolling contact of the rolling surface of first gyro wheel unit and the inner side lower surface of guide rail, the rolling surface in second gyro wheel unit and the inner side upper surface of guide rail rolling contact, can effectively balance the forward torque generated by iron roughneck, ensure that walking frame moves smoothly, avoid the jamming phenomenon, greatly improve the stability and reliability of walking device operation. The walking device for oil drilling iron roughneck can install iron roughneck on the front end of walking frame, and when the drive mechanism drives walking frame to move to the far end along guide rail, the iron roughneck on walking frame extends the far end of guide rail, and can retract into guide rail when iron roughneck is on standby, effectively release the wellhead space.
