The invention provides a hencoop with height adjusted by a pin shaft. The hencoop comprises an upper cover and a lower cover, wherein the upper cover and the lower cover are provided with a plurality of through holes; the upper cover and the lower cover are of the same shape; the upper cover is larger than the lower cover in size; the perimeter of the section of the upper cover is larger than that of the section of the lower cover; the upper cover and the lower cover can be buckled and connected together; fixing plates are arranged at the two ends of a wall of the upper cover; the fixing plates are provided with a plurality of fixing holes; the fixing holes and the fixing plate are formed integrally during manufacturing; the fixing plates are fixedly connected with the upper cover; the two ends of a wall of the lower cover are provided with locking plates; the locking plates are provided with a plurality of locking holes; the locking holes and the locking plates are formed integrally during manufacturing; the locking plates are fixedly connected with the lower cover; fixing rods are fixed in the fixing holes; the fixing holes correspond to the locking holes one by one; the fixing rods can pass through the fixing holes and the locking holes, so that the upper cover and the lower cover are fixed. The hencoop is simple in structure, is convenient to use, has a good ventilation effect, and is adjustable in height.

The invention relates to the field of metallurgical equipment, in particular to a continuous casting machine tundish submersed nozzle baking furnace. The continuous casting machine tundish submersed nozzle baking furnace comprises a furnace body, wherein two baking chambers are arranged in the furnace body, each baking chamber is provided with a spraying nozzle, each spraying nozzle is connected with a mixing valve, each mixing valve is connected with an air inlet pipe and a fuel gas inlet pipe, each air inlet pipe and each fuel gas inlet pipe are respectively provided with a control hand valve, an installation plate is arranged at the top of each baking chamber, a clamping groove is formed in each installation plate to fix a submersed nozzle, the furnace body is provided with a furnace door, a heat-preservation layer is arranged at the inner side of the furnace door, a flame retardant layer is arranged on the inner wall of each baking chamber, a heat preservation plate is formed at the top of the furnace body and provided with openings matched with the submersed nozzles, pulleys are arranged at the bottom of the furnace body, and pothooks are arranged at the top of the furnace body. The continuous casting machine tundish submersed nozzle baking furnace has the advantages of being safe to operate, capable of meeting production requirements, capable of guaranteeing baking quality and convenient to move and transport, saving energy and the like.

The invention discloses a quick connection method for prefabricated steel pipe constraint type steel concrete pier columns and a cover beam. The method comprises the steps that when the steel concrete cover beam is prefabricated, reserved holes used for connecting the two elements are formed in the portions, corresponding to the pier columns, of the steel concrete cover beam; at the bottom interfaces of the steel pipe constraint type steel concrete pier columns and the cover beam, profile steel flange plates extend to the positions under stressed reinforcing steel bars arranged at the top of the cover beam, steel pipes at the peripheries of the pier columns do not extend, and steel bars connected with the cover beam need to be embedded in stand column sections at the top ends of the pier columns, wherein the anchorage length of the steel bars and the depth that the steel bars are embedded into the cover beam need to meet the related bridge design specification construction requirements; transverse steel bars are arranged in profile steel flange plate anchorage holes formed in the reserved holes of the cover beam in a penetrating mode and connected together with the steel bars arranged at the peripheries of the reserved holes of the cover beam, and concrete is poured in the reserved holes. According to the method, the problems that the construction occupation site is large, the construction period is long, part of connection work procedures are trouble, and welding is difficult are solved, the connection reliability and bearing capacity of this kind of bridge piers are guaranteed, and the resistance, the shock resistance and the rigidity of the bridge piers are improved.

The invention provides a method for using a hencoop with height adjusted by a pin shaft. The method comprises the following steps: using a lower cover separately: putting baby chicks into the lower cover, making fixing rods pass through locking holes, and exposing the two ends of the fixing rods outside locking plates so as to bring convenience to manual lifting, loading and transporting; or using an upper cover separately: flipping the upper cover, putting the baby chicks into the upper cover, making the fixing rods pass through fixing holes and exposing the two ends of the fixing rods outside the fixing plates so as to bring convenience to manual lifting, loading and transporting; or using the upper cover and the lower cover in a combined way: making the opening direction of the upper cover face the opening direction of the lower cover, after introducing the baby chicks, buckling the upper cover and the lower cover together, making fixing holes in the upper cover correspond to the locking holes in the lower cover, selecting appropriate fixing holes corresponding to the locking holes according to a needed height, and making the fixing rods pass through the fixing holes and the locking holes to fix the upper cover and the lower cover together. The method disclosed by the invention is simple; and a used product is simple in structure, is convenient to use, has a good ventilation effect, and is adjustable in height.
