This utility model discloses an optical glass drying device, including a drying chamber, a conveyor line, and a carrier. The carrier consists of a U-shaped portion and symmetrically arranged clamping and limiting portions. The clamping portions are positioned between the symmetrically arranged limiting portions, forming a clamping area for holding the optical glass. A limiting area is formed in the middle of the limiting portions, and the U-shaped portion is located within the gap. This optical glass drying device conveys the optical glass to be dried through the cooperation of the conveyor line and the carrier. The carrier can restrict the position of the optical glass while ensuring contact with the optical glass with a minimal contact area, thus preventing damage to the surface of the optical glass and ensuring its smoothness. This helps to prevent any damage to the optical glass during drying while shortening the drying time and accelerating the drying speed.

This invention provides a reference threshold setting device for an axle counting system, comprising: a main control unit for collecting button operation information and generating a safe reference threshold setting command; and a method for setting a reference threshold for an axle counting system, comprising: the axle counting board collecting detection parameters of axle counting detection points in real time, and the detection parameters when there are no vehicles within a specified range of the axle counting detection points being the target object for setting the reference threshold; the method further comprising the setting device sending a reference threshold setting command to the axle counting board through the axle counting host bus or the axle counting board interface. Compared with the prior art, this invention has the following advantages: it uses software commands to set the current no-vehicle detection parameters as the reference threshold, eliminating the need for hardware debugging of the reference threshold, greatly reducing the workload of axle counting system debugging, and making on-site debugging of axle counting equipment more convenient; by changing the reference threshold adjustment method to software adjustment, there will be no parameter drift or hardware damage.

A safety hook capable of being automatically disassembled after a lifting steel wire rope is broken comprises a pulley and a hook head, and the pulley and the hook head are connected through a stable connecting assembly so that a heavy object can be kept stable when being lifted; the stable connecting assembly comprises a connecting frame and a balance beam, the connecting frame is connected with the pulley and the balance beam, and the balance beam is connected with the connecting frame and the lifting hook head; the connecting frame is connected with the pulley through a rotating shaft on the pulley connecting lug plate, a safety device is arranged at the joint of the connecting frame and the pulley, and the safety device triggers the safety hook to be disassembled when a rope breaking accident occurs; the safety lifting hook is disassembled, so that a lifting and hoisting mechanism on one side of the lifting equipment without rope breakage can be prevented from being damaged due to excessive overload, metal structures except the lifting hook head are prevented from being damaged due to serious unbalance loading, the caused damage and property loss are reduced, and the safety of the lifting equipment in the using process is also greatly improved.
