This invention discloses a crankshaft axis inspection instrument based on machine vision, belonging to the field of crankshaft inspection technology. The machine vision-based crankshaft axis inspection instrument includes an inspection table and a primary lead screw slide mounted on the inspection table. A primary slide is slidably mounted on the primary lead screw slide, and a mounting frame is fixed on the primary slide. A vision camera for visually inspecting the crankshaft axis is mounted on the mounting frame. A support frame is vertically fixed on the mounting frame, and an illumination component coaxial with the vision camera is mounted on the support frame. Two sets of follow-up support wheels are provided below the crankshaft main journal to prevent deformation due to their own weight. A base component is provided on the support frame to adjust the position and angle of the follow-up support wheels. A base is mounted on the base component, and an adaptive support sensing component is provided on the base to sense the pressure of the follow-up support wheels supported below the crankshaft main journal. This inspection instrument can support and limit the crankshaft main journal, reduce axis inspection interference, and improve the accuracy of visual inspection.

The utility model relates to the field of household appliances, and specifically provides a cooking utensil. The cooking utensil comprises a main body, a juice receiving disc and an upper cover, the juice receiving disc is used for being placed on the main body, the upper cover is used for being placed on the juice receiving disc, the juice receiving disc is provided with a water seal groove and a buffer groove extending along the circumference of the juice receiving disc, the buffer groove surrounds the water seal groove, when the upper cover is placed on the juice receiving disc, the side wall of the upper cover extends into the water seal groove, the bottom wall of the buffer groove is provided with a backflow hole, and water in the buffer groove can flow into the inner cavity of the main body through the backflow hole. The cooking utensil of the utility model sets the juice receiving disc between the main body and the upper cover, the side wall of the upper cover extends into the water seal groove, so that water forms a water seal in the water seal groove, when the water forming the water seal overflows, the water flows into the buffer groove from the outer groove part, then is discharged through the backflow hole and flows into the inner cavity of the main body, thereby avoiding that water escapes from the cooking utensil to affect the operation environment and even scald personnel.

This invention relates to a bidirectional protection device and method for lifting beams and wire ropes. The device includes at least one protection module, comprising an upper protection seat and a lower protection seat, which are fixedly connected by a plug-in mechanism. The upper protection seat has a rebar clearance groove; the lower protection seat has a connecting groove that connects to a wedge-shaped connecting plate and is equipped with the plug-in mechanism. The upper and lower arc-shaped rope support grooves together form a wrapping channel, which has an arc-shaped groove in which an arc-shaped slider is installed. Both the upper and lower protection seats have inner grooves containing elastic damping mechanisms. The inner walls of both the upper and lower protection seats are covered with a biomimetic damping protective layer. This invention converts tensile force into self-increasing clamping force through wedge self-locking, is adaptable to various types of precast concrete beams, is easy to assemble and disassemble, reusable, and equipped with standardized protection methods, significantly improving lifting safety and construction efficiency.

This invention discloses an intelligent displacement-type straw stacking device with compaction function, belonging to the technical field of straw stacking devices. It includes a base, a pressing assembly, an adjusting assembly, a guide cylinder, an electric rotating drum, and a guiding assembly. During the edge expansion process, the movable side column drives the bottom adjusting component to move synchronously to both sides. Through the cooperation of the sliding column and the inclined groove, the drive roller and the detection roller achieve stable clamping of the row of straws. After the detection roller and the drive roller clamp the row of straws, under the drive of a second motor, the detection roller and the drive roller rotate synchronously through transmission components such as gears, force transmission rings, and arc-shaped piston rods, applying a stable downward traction force to the row of straws, pulling out the blockage material in the expansion channel and achieving deblocking. After deblocking is completed, the control system automatically resumes the operation of the electric rotating drum and reverses the drive of the edge expansion assembly and the deblocking and anti-breakage assembly to reset, achieving seamless connection between the deblocking process and normal feeding, avoiding prolonged equipment shutdown due to material blockage.
