This invention relates to the field of trestle bridges, specifically to a trestle bridge for construction across railway lines and its usage method. The trestle bridge includes a trestle bridge module, approach bridge modules, a traveling module, and a support and guide module. The trestle bridge module is erected within a reserved passage area on the external track line. The approach bridge module is mounted on one side of the trestle bridge module via a rotating shaft and is pulled by the trestle bridge module. Two sets of traveling modules are installed on both sides of the ends of the trestle bridge module. The support and guide module is erected on the side of the reserved passage area facing the track. The hydraulic motor in the traveling module, in conjunction with the traveling wheels, drives the trestle bridge module to move rapidly along the guide roller seats of the support and guide module. Combined with the folding and unfolding functions of the approach bridge module, this enables rapid erection and dismantling of the trestle bridge, significantly shortening construction preparation time and dismantling cycle, avoiding prolonged interruptions to railway operations, and effectively solving the problems of long construction cycles and dismantling interference with normal railway operations caused by traditional trestle bridges.

This invention discloses a heated tobacco cooling unit with enhanced thermal conductivity and a heated tobacco product, comprising a carrier sheet, several metal foils, and several phase change cooling materials. The carrier sheet has several perforated holes. Several metal foils are disposed on at least one side of the carrier sheet and cover the perforated holes. The metal foils are spaced apart and discretely arranged. The phase change cooling materials are filled within the perforated holes using the metal foils as a carrier. The carrier sheet containing the metal foils and phase change cooling materials is formed into the heated tobacco cooling unit by at least one of the following methods: winding, folding, gathering, bending, and pleating. The metal foils are regularly and intermittently distributed along the longitudinal direction of the tobacco strip. The cooling unit has multiple longitudinally extending channels, and the porosity of the cross-section is 40%-90%. The heated tobacco cooling unit with enhanced thermal conductivity of this invention has the advantages of high latent heat of phase change, low thermal hysteresis effect, high heat absorption efficiency, apparent stability without collapse, and no leakage.

In this utility model, through the linkage design of the universal wheels, threaded rod, sliding rod, and foot plate, the device can be quickly deployed and withdrawn. In use, rotating the threaded rod makes the foot plate fit with the ground, providing stable support, and can be further reinforced with fixing holes or counterweights; during transfer, the reverse operation makes the foot plate lift off the ground, and the universal wheels can be used for easy movement, greatly reducing manpower consumption and significantly improving the efficiency of facility transfer.

This application discloses an adaptive energy-saving operation control system and method for escalators that detects passenger flow, relating to the field of intelligent control technology. It solves the technical problem in existing technologies where the threshold is generally set to a fixed value when comparing passenger flow with a threshold. This can lead to congestion and potentially stampedes during peak periods like holidays. This application utilizes data sensors to collect real-time passenger flow data entering the escalator area; it controls the escalator's start and stop based on the real-time passenger flow; it adjusts the escalator's operating speed based on the real-time passenger flow; it predicts passenger flow based on historical data; and it determines the escalator's maintenance and inspection time based on the prediction results. This system not only controls start and stop but also adjusts the operating speed based on real-time passenger flow. Appropriate speed reduction can bring exponential energy savings, directly reducing electricity costs and extending equipment lifespan.
