This utility model discloses a hook assembly and lifting equipment based on anti-disengagement of steel ingot molds, relating to the field of steel ingot mold lifting. The key technical points are: it includes an installation part and an elastic telescopic part located below the installation part. A hook is installed on the telescopic part of the elastic telescopic part. The elastic telescopic part has a high-strength spring and a damper. The effect is that when the hook lifts the steel ingot mold, the shaking and impact forces generated during the lifting process due to starting and stopping inertia and running vibrations are first transmitted to the elastic telescopic part. The high-strength spring in the elastic telescopic part absorbs some energy through its own elastic deformation, reducing the impact force. At the same time, the damper plays a buffering role, effectively dissipating the remaining energy, reducing the vibration amplitude and frequency, thereby reducing the periodic alternating load borne by the connection between the hook and the steel ingot mold, avoiding hook fatigue fracture, preventing relative displacement or disengagement between the steel ingot mold and the hook, and ensuring lifting safety.

The application discloses a compressor assembly and an air conditioner. The compressor assembly comprises a compressor, a pipeline connected with the compressor, a buffer assembly and a mounting seat. The buffer assembly is connected with the mounting seat and the compressor and comprises an elastic member.

When the buffer assembly is used for buffering the torsion generated by the shutdown of the compressor, the elastic member can generate a reaction force to buffer the torsion of the compressor, thereby, it is beneficial to avoid the swing of the pipeline (the suction pipe and / or the exhaust pipe) connected with the compressor, and further, it is beneficial to avoid the problem that the stress of the pipeline exceeds the standard or even the pipeline is broken due to fatigue. When the buffer assembly is used for buffering the torsion generated by the start of the compressor, the working principle and the role of the buffer assembly are the same as the foregoing, and details are not described herein.

This invention relates to the field of construction waste recycling technology, specifically to a multi-stage anti-clogging vibrating screen for asphalt pavement milling materials. The screen includes a screen box containing a first screening component, a limiting component, and a clearing mechanism. The first screening component includes multiple cantilever screen bars. The limiting component includes a limiting plate with multiple limiting grooves. A clearing mechanism is located beside the limiting component, comprising a drive component and rake teeth. An air outlet is located beside the clearing mechanism. The rake teeth insert into the gaps between the multiple cantilever screen bars to break the mechanical jamming of the material. Simultaneously, the directional airflow from the air outlet continuously cools the core area of ​​frictional heat generation between the rake teeth and the limiting grooves, strictly controlling the contact surface temperature below the asphalt softening point. This physical breaking combined with temperature control fundamentally eliminates the problem of screen clogging caused by asphalt melting and stringing due to frictional heat.
