The invention discloses a boarding ladder for a ship. The boarding ladder comprises handrails, a boarding ladder body and pedals. Two fixing supporting rods are symmetrically arranged on the boardingladder body and welded through second supporting rods which are arranged from top to bottom at equal intervals. The pedals are welded to rotary shafts correspondingly, rotary discs are rotatably connected to one sides of the ends of the fixing supporting rods, and the other sides of the ends of the fixing supporting rods are rotatably connected with a limiting frame through shaft sleeves. In the boarding ladder for the ship, when the height of the ship is not consistent with the elevation of a dock, the pedals are made to be parallel to the horizontal plane by rotating the rotary discs so thatthe stairway-shaped boarding ladder can be formed; when the height of the ship is consistent with the elevation of the dock, similarly, the pedals are made to be parallel to the horizontal plane so that a horizontal bridge can be formed; and through the structure, the applicability of the boarding ladder can be higher, bridge connection of different positions and heights can be met simultaneously, and convenience is brought to boarding.

The invention discloses a drawing frame device for yarn production and its use method, which comprises a support seat, a lifting plate, a side plate, a bundler, a winding seat and a conveying seat. The two ends of the top of the support seat are slidingly connected with side plate; the two side plates are slidably connected with a lifting plate; the present invention drives the two sliders 5 to move relative to each other or away from each other by rotating the screw mandrel 3, and then adjusts the distance between the dust removal rollers. Different distances can be used to remove dust and guide different types of yarns; by rotating the outer ring, the rocker arm is driven to rotate, so that the connecting rod moves in the linear groove, and then drives the movable bar to insert or protrude into the winding reel to adjust the rewinding reel The size of the radius can rewind yarns of different sizes, avoiding that conventional equipment can only rewind one type of yarn.

The invention prepares the austenitic stainless steel with stronger chloride corrosion resistance, which fills up the technical blank of the high-carbon austenitic stainless steel.

The invention discloses a chemical analysis method for measuring molybdenum content in high-tungsten molybdenum recycled materials. According to the different properties of the high-tungsten molybdenum recycled materials, different pre-treatment methods are used with a total differential spectrophotometric method and visible spectrophotometry to eliminate interference of tungsten to detection andcorrect the molybdenum content of residues generated during the process so as to obtain accurate results. The chemical analysis method includes the steps of preparing a reagent; measuring molybdenum in molybdenic acid and sodium molybdate; measuring molybdenum in commercial molybdenum oxides; correcting the detection of molybdenum in the residues; determining the detection results. The chemical analysis method performs pre-treatment on the high-tungsten molybdenum recycled materials different in property, effectively eliminates the interference of tungsten to the detection via the total differential spectrophotometric method and corrects the molybdenum in the residues via the visible spectrophotometry; the chemical analysis method has the advantages of good result accuracy, high precisionand good applicability.

The invention provides a wheel braking stored-energy machine which not only can convert kinetic energy generated by rotation of a wheel into mechanical energy and store, but also can converted the stored mechanical energy into kinetic energy to release to the wheel so as to lead the wheel to rotate without the action of external force. The stored-energy machine takes the wheel as a driving link and arranges a barrel-packaged casing on a relevant position of the wheel, and the external end surface of the casing connected with an annular gear in a mechanical manner is engaged with a primary gear to deliver motive power; a shaft is provided with a roller assembly which can axially move and is composed of a spline, a roller, a gear and a control mechanism; a loopy spring is a stored-energy member, and the inner and outer ends thereof are respectively fixed on the roller and the casing; the primary gear and an intermediate gear are arranged on a support of the shaft in a mechanical manner; and the gear of the roller assembly and the intermediate gear are engaged to perform braking and store energy through operating the control mechanism by external motive power, and the kinetic energy is released to the wheel so as to lead the wheel to rotate at a certain stroke when the gear of the roller assembly and the intermediate gear are separated.

The invention belongs to the field of technologies for manufacturing and applying sports equipment, and particularly relates to an ice and land dual-purpose detachable ice hockey puck. The ice and land dual-purpose detachable ice hockey puck comprises a puck, an upper puck cover, a lower puck cover, balls and ball balance weights. Grooves are formed in the upper surface and the lower surface of the puck, a plurality of inserting and pulling holes are formed in the grooves in a perforated manner, the balls and the ball balance weights can be fixedly inserted into the inserting and pulling holes or can be pulled out from the inserting and pulling holes, and projections which are matched with the grooves in the puck are arranged on the upper puck cover and the lower puck cover, so that the upper puck cover and the lower puck cover can be fastened on the puck or can be separated from the puck. The ice and land dual-purpose detachable ice hockey puck has the advantages that the ice hockey puck can be used on ice and lands, and accordingly requirements that ice hockey sports enthusiasts can carry out ice hockey sports without constraints of special places at any seasons can be met.

The invention provides a treatment agent for water-based drilling fluid drilling cuttings. The treatment agent is composed of 70-85wt% of intermediate product, 10-20wt% of clay powder and 5-10wt% of gypsum powder, the intermediate product is composed of 200-300ml of water, 21-37g of alcohol-type monomer, 12-18g of cyanate-type monomer, 32-45g of propionic acid type monomer, 6-9g of dopamine, 1.5-3.0g of dicyclohexyl carbodiimide and 0.5-1.0g of organic amine. The invention further provides a preparation method of the treatment agent. The treatment agent is low in adding amount, good in solidifying effect and high in suitability.

The present invention relates to a kind of chocolate which can be used for 3D printing to make the chocolate particles finer and solve the problem of clogging the printing head and its preparation method, which comprises the following components: cocoa butter substitute, xylitol, maltitol, milk powder, phospholipid, polyglycerin Ricinol Ester, Vanillin, Salt and Fragrance.
