According to the utility model, electrical modularized centralized accommodating arrangement can be realized, power supply is supplied in a centralized manner, the requirement of effectively shortening the length of electrical connection wires of required loads and circuits can be met, the space in the cabinet is saved, electrical connection between a plurality of loads at different positions and the same circuit can be facilitated, the connection is stable and reliable, and the convenience and effectiveness of power supply are improved.

The utility model discloses a loading and unloading unit of an automatic spindle loading and unloading device. The loading and unloading unit comprises a sliding bracket, an adjusting frame and a push-pull assembly, a plurality of supporting rods are arranged on the sliding bracket, every two supporting rods form a group to form a supporting station, the supporting rods are movably inserted into an adjusting frame, and the adjusting frame is rotatably arranged on the frame; the push-pull assembly comprises a main push cylinder, a push plate and an auxiliary push cylinder; the main push cylinder is arranged on the adjusting frame; a push rod of the main push cylinder is connected with the sliding bracket; the auxiliary pushing cylinder is arranged on the sliding bracket, the pushing plate is connected to a pushing rod of the auxiliary pushing cylinder, and the pushing plate is located above the supporting rod of the supporting station; when the spindles are loaded, the main pushing cylinder drives the sliding bracket, and the auxiliary pushing cylinder drives the pushing plate to push the spindles into the working positions of the spindle shafts in a step-by-step pushing mode. Spindles are loaded in a step-by-step propelling mode, the requirement for the length of a spindle shaft is lowered, the loading efficiency of the spindles is improved, and the spindle loading device is suitable for old machine transformation projects.

The invention discloses a method for measuring the flow of an auxiliary air pipeline of a combustion-supporting air pipeline system of a melting furnace, and the auxiliary air pipeline is a Venturi tube and is connected with auxiliary air branch pipes of a group of paired small furnaces of the melting furnace; the method comprises the steps that S1, the air pressure of a negative pressure point of a throat section of an auxiliary air pipeline is detected and compared with the air pressure of an atmospheric reference positive pressure point, the pressure difference is obtained, and a pressure difference signal representing the auxiliary air flow in the throat section of the auxiliary air pipeline is obtained; s2, acquiring a real-time temperature signal and a real-time pressure signal of gas in the air assisting pipeline; and S3, by means of the real-time temperature signal and the real-time pressure signal, temperature and pressure compensation correction is conducted on the initial flow obtained through calculation based on the pressure difference signal, so that an accurate real-time auxiliary air flow signal is obtained. According to the method, by integrating real-time collection and temperature and pressure compensation correction of temperature and pressure signals, measurement errors caused by working condition fluctuation are effectively eliminated, and the accuracy and stability of flow data and the adaptability to the production environment are remarkably improved.
