The invention discloses a ship floating maintenance platform which comprises longitudinal floating bodies on the two sides and a transverse floating body vertically and fixedly connected with the longitudinal floating bodies. A ship tail lifting device stretches across the middles of the two longitudinal floating bodies, and comprises a pair of vertical gantries, a ship tail lifting beam and a ship tail lifting beam lifting mechanism, and the ship tail lifting beam stretches across the inner sides of the two longitudinal floating bodies and comprises a lower cross beam and a pair of stand columns. The lower ends of the vertical segments of the stand columns are fixedly connected with the two ends of the lower cross beam respectively, and the ship tail lifting beam lifting mechanism comprises a fixed pulley set, a movable pulley set and a loading winch. A stand column lifting guide mechanism is arranged between concave openings in the inner sides of the longitudinal floating bodies and the vertical segments of the stand columns, and stand column locking mechanisms are symmetrically arranged on the two sides of the stand columns. The ship floating maintenance platform is reasonable in arrangement and fast and convenient to use, the tail of a ship can be lifted fast, a rudder blade and a propeller are made to be out of water for maintenance, and maintenance cost is lowered. Use time is short, and work efficiency is high. The ship repairing cost is greatly lowered.

The invention provides a warming and humidifying machine for tobacco storing. The machine comprises a rack, tank wall boards arranged on the rack, a fabric trolley, a covering device and a warming and humidifying device, wherein the tank wall boards are mounted on the rack to form a storing cabinet with an upper end opening, the upper sides of the tank wall boards on two sides of a body of the storing cabinet are connected with a fabric trolley rail, and the fabric trolley is glidingly arranged on the fabric trolley rail; the covering device comprises a fabric coiling roller, a cable coiling wheel, a fabric coiling roller motor connected with the fabric coiling roller, a cable coiling wheel motor connected with the cable coiling wheel and covering fabric, wherein the fabric coiling roller, the cable coiling wheel, the fabric coiling roller motor, the cable coiling wheel motor and the covering fabric are arranged on two sides of the upper part of the rack; the fabric coiling roller motor is used for driving the fabric coiling roller to rotate to realize coiling of the covering fabric, and the cable coiling wheel motor is used for driving the cable coiling wheel to coil a stay cable on the cable coiling wheel; the warming and humidifying device is used for spraying water and steam to leaves in the storing cabinet to play a role in warming and humidification. The warming and humidifying machine can store leaves, can perform moisture regain on the leaves and can reduce occupied ground, save cost, reduce rags and save energy.

The invention discloses a transcoding method for a denary shift of a transformer on-load tap-changer and a transcoder. The transcoding method aims to convert denary output shift pressure regulating signals of a transformer on-load tap-changer to one-to-one correspondence pressure regulating signals through a shift transcoder and comprises on-site display, remote display, on-site and remote display directly used for the denary shift. Converting the denary output shift pressure regulating signals to the one-to-one correspondence pressure regulating signals comprises the following steps: I. the transcoder outputs one-to-one correspondence shift pressure regulating signals W1-W7; II. the transcoder outputs one-to-one correspondence shift pressure regulating signals W8-W10; and III. the transcoder outputs one-to-one correspondence shift pressure regulating signals W11-W17. The invention is suitable for a 110KV denary shift on-load transformer and can convert the denary shift information ofthe transformer to one-to-one correspondence shift information which can be identified by a main transformer measurement and control system. The invention has the advantages of simple design, low cost, convenient installation and great reliability.

The invention belongs to the field of concrete preparation, in particular to the field of preparing high-strength anti-fracture concrete by using waste materials. The invention discloses a method for preparing high-strength anti-fracture concrete by utilizing waste materials, wherein the raw materials are coarse aggregate, rapid-hardening sulphoaluminate cement, modified waste residue, lime, sand, water reducer, early strength agent and thickener And modified polypropylene fiber, the coarse aggregate is preliminarily crushed and finely crushed, mixed with the rest of the material, and distributed evenly through the rotating chute, and at the same time, the spray assembly is turned on to spray water, and the motor is turned on to stir. The beneficial effect of the present invention is that the strength and toughness of the concrete are improved through the modified waste slag and the modified polypropylene fiber, and the concrete mixing drum has the advantages of high mixing efficiency, integration of raw material preparation and mixing device, real-time dynamic control of material ratio, etc. Excellent effect.

The invention discloses a blast furnace coal powder injection combustion adjuvant and an application method thereof. The combustion adjuvant is a powdery mixture, and is composed of, by mass: 50-80% iron oxide red, 0-20% of rare earth oxide, 0-20% CaO, 0-20% of MgO, 0-30% of manganese-series oxide, and balance of impurities. According to the invention, the coal powder is injected into a blast furnace raceway by using a coal gun according to a formula that: AP=Vad / 16.99-(FCad-62.17%) / 18.16+(T-817.15)*100% / 609.45+(CSR-55.52%) / 24.14+OEB / 5.27. According to the invention, on a basis that a coal injection effect is ensured, iron oxide red can be more effectively recovered and utilized, such that enterprise by-products can be recycled, outsourcing cost can be reduced, and enterprise operation cost reduction can be finally realized. With the combustion adjuvant and the method, a novel approach is developed for blast furnace energy saving and emission reducing.
