This invention belongs to the field of X-ray nondestructive testing technology, and particularly relates to a variable-diameter adaptive X-ray fluoroscopic inspection platform. It includes an inspection platform, a column, a lifting screw, and mounting bases. A downward-opening semi-circular hollow stator disk is connected between two mounting bases, and a rotor disk is rotatably mounted inside the stator disk. Radial guide grooves are formed on the stator disk, and corresponding arc-shaped cam grooves are formed on the rotor disk. Slide seats are slidably connected within both the grooves and the cam grooves. By adjusting the motor to drive the worm gear transmission, the rotor disk rotates, and the arc-shaped cam grooves push each slide seat to slide synchronously radially along the radial guide grooves, achieving multi-point synchronous diameter change from a single drive source. The X-ray source and detector are mounted on the slide seats, maintaining a positive-relative scanning configuration at all times, eliminating image distortion and detection blind spots inherent in traditional L-shaped architectures. This invention features a simple and reliable structure, adaptively adjusts the inspection aperture, accommodates both large-diameter vehicles and small-diameter vehicles, and is suitable for efficient passage of multiple vehicle types in mixed traffic.

This utility model discloses an energy-saving drying device for stretch film, relating to the field of stretch film drying technology. It includes a chassis and a chiller. A winding mechanism is installed on the inner wall of the chassis, and a sliding groove is formed on the outer surface of the chassis. This utility model, through the cooperation of a slidingly connected limiting ring in a limiting component, a magnetic pull plate, and an arc-shaped magnetic block embedded in the rotating shaft, constitutes a magnetic adaptive adjustable limiting system. This system has the function of quickly adapting to and clamping stretch film rolls of different widths. It solves the problem that traditional fixed baffles or limiting devices with non-adjustable spacing cannot flexibly adapt to film rolls of various lengths. The effective distance between the sliding limiting ring and the support plate can be easily changed to accommodate paper cores of different lengths. Magnetic attraction is used to achieve pre-fixation and rapid release of the pull plate, avoiding the cumbersome operation and low efficiency problems caused by mechanical methods such as threaded locking.
