This invention discloses a fixing structure for a high-power frameless motor used in humanoid robots, relating to the field of frameless motor technology. It includes: a stator assembly with positioning blocks fixed to both end faces of the stator assembly, two positioning blocks on each end face; and a rotor assembly housed within the stator assembly. This invention employs a structure with a double-disc body, double rotating rings, and a connecting seat. Relying on the positioning blocks and positioning grooves, and the protrusions and grooves forming a double alignment design, combined with a locking mechanism, it can quickly achieve concentric positioning of the stator assembly and rotor assembly, while effectively limiting radial movement of the rotor assembly. Furthermore, the connecting mechanism adopts an adjustable clamping structure design, which can adapt to output shafts of different sizes, ensuring coaxiality between the output shaft and the stator and rotor assemblies. This eliminates the need to replace the motor body or customize an adapter flange, significantly improving the equipment's versatility and adaptability to different operating conditions.

This utility model relates to the field of concrete composite jacking technology, specifically a steel-socket type reinforced concrete composite jacking pipe, including a jacking pipe with a sealing mechanism fitted on it. The sealing mechanism includes a pressure plate and a bushing. The bushing is snapped onto the jacking pipe, and several inserts are fixedly connected in a ring at equal intervals on the bushing. The bushing and inserts are snapped onto the pressure plate. A sleeve is fitted onto the pressure plate, and several inserts are fixedly connected at equal intervals on the sleeve. A water-stop rubber plate and a pressure plate are fitted onto the inserts, and the pressure plate is fixed to the inserts with bolts. Through bushing snap-fit ​​positioning, axial pressing of the water-stop rubber plate, and bolt fixing and locking, a triple seal is formed. The water-stop rubber plate expands radially after being pressed by the pressure plate, completely filling the gap of the jacking pipe interface, which helps to prevent leakage.

The utility model discloses a tail gas aftertreatment assembly. The tail gas after-treatment assembly comprises a shell, a carrier, heat insulation cotton located between the carrier and the shell in the radial direction of the tail gas after-treatment assembly, a first check ring assembly located on one side of the carrier in the axial direction of the tail gas after-treatment assembly, and a second check ring assembly located on the other side of the carrier in the axial direction of the tail gas after-treatment assembly. The first check ring assembly comprises a first check ring and first steel wool located between the first check ring and the carrier in the axial direction of the tail gas aftertreatment assembly. The second check ring assembly comprises a second check ring and second steel wool located between the second check ring and the carrier in the axial direction of the tail gas aftertreatment assembly. Compared with the prior art, the tail gas after-treatment assembly omits a traditional gasket, and cost is saved.

The utility model discloses a corrugated roller with a tooth-shaped wave structure, and belongs to the technical field of corrugated rollers. The corrugated roller comprises the connecting roller, the connecting grooves are formed in the two ends of the connecting roller, the connecting blocks are clamped in the connecting grooves, the connecting roller and the connecting disc can be rapidly disassembled and assembled through clamping of the connecting grooves and the connecting blocks, parts can be conveniently maintained and replaced, and the corrugated roller can be independently replaced when parts of corrugated teeth of the corrugated roller are damaged due to abrasion, collision and the like. Therefore, the maintenance time and cost are greatly reduced, the economical efficiency and sustainability of production are improved, then a moving ring is used for driving a moving block to slide in a sliding groove, through clamping and fixing of a locking column and a positioning groove, the position of the corrugated roller in the circumferential direction of the connecting roller can be adjusted, the production requirements of different wave shapes or tooth shapes are met, the equipment universality is improved, and the production efficiency is improved. And meanwhile, the sliding blocks are matched with the sliding grooves, radial movement of the corrugated roller is limited, stability during rotation is ensured, and deviation or shaking is avoided.
