Disclosed is a spinning-drawing-winding device for industrial polylactic-acid fiber, including a double-surface oiling mechanism (11), a filament shearing-suctioning device (12), a pre-interlacer (13) and a splitting filament roller (14) disposed in sequence according to a production process; a drawing-winding device (200) cooperates with a spinning device(100), a tow passing from the spinning device (100) through the double-surface oiling mechanism (11), the filament shearing-suctioning device(12), and the pre-interlacer (13) in sequence until the tow is conveyed to the splitting filament roller (14); the drawing-winding device (200) and the spinning device (100) are configured as a parallel configuration, so that the tow between the spinning device (100) and the splitting filament roller (14) are arranged in a vertical direction and is tangential to the splitting filament roller (14), and therefore the tow is without deflection, thereby avoiding damaging the tow due to a friction caused by a higher deflection.

The present disclosure provides a rotor lock prevention system for an electric vehicle and related methods. Rotor lock prevention systems and related methods are disclosed. An example apparatus includes an electric motor having an output shaft; a drive axle for driving one or more wheels of the vehicle; a torque converter for operatively coupling the output shaft of the electric motor and the drive shaft; and a clutch movable between an open position and a closed position. The clutch fluidly couples the output shaft and the drive shaft of the electric motor when the clutch is in the open position. When the clutch is in the closed position, the clutch enables the electric motor to bypass the torque converter to mechanically couple the output shaft and the drive shaft of the electric motor.

A photovoltaic tracking system with special cross section and eccentricity overcoming device, the main beam cross section is a rounded square tubular structure; the eccentricity overcoming device is installed between the common column and the main beam of the photovoltaic tracking system, and comprises a mechanism support, a mechanism body and a mechanism fixing seat which cooperate with each other; the mechanism support is fixed on the main beam, and the mechanism fixing seat is fixed below the common column of the photovoltaic tracking system; the mechanism body comprises a hydraulic cylinder and a cylinder barrel which cooperate with each other, the upper end of the cylinder barrel is hinged on the mechanism support and moves under the drive of the mechanism support on the main beam, the tail end of the hydraulic cylinder is hinged on the mechanism fixing seat and forms relative movement with the cylinder barrel, the limiting structure of the cylinder barrel and the two springs act on the springs respectively to compress the springs and generate a thrust on the mechanism support to overcome the gravity eccentricity of the rotation of the photovoltaic tracking system, the torsional performance of the main beam is improved and the torsional deflection is reduced, the damping effect is achieved, and the rotation eccentricity of the photovoltaic tracking is overcome.

This invention discloses a construction method for a pipeline installation lifting gantry device suitable for confined spaces. The pipeline installation is completed through steps including modular gantry assembly, pipeline traction or coordinated transport, synchronous lifting and lateral positioning, segmented acceptance, and hydrostatic testing. Laterally movable pulley assemblies are installed on the upper and lower parts of the gantry, working in conjunction with a self-locking lifting mechanism to achieve synchronous lateral movement and alignment of the pipeline while it is being lifted, allowing the pipeline to quickly align with the bracket and be secured. This method reduces reliance on large hoisting equipment in confined environments such as culverts and pipe galleries, minimizing manual handling and repeated lifting and lowering, and improving installation efficiency and alignment accuracy. Simultaneously, measures such as travel limiters, segmented inspection stops, diagonal bracing for stability, and base leveling enhance operational safety and overall stability, and reduce the risk of collision and wear on the pipeline's external anti-corrosion layer.
