Abstract
The utility model provides a nozzle with adjustable height. A round cover is arranged on the gravity center of the upper end face of the nozzle body, a T-shaped head at the lower end of a screw rod is movably connected into the round cover, the upper end of the screw rod penetrates through a protection hood and a lower box body and then is connected in a bolt hole in the center of a worm wheel, and the worm wheel is meshed with a worm. The worm wheel and the worm are fixed on an upper box body, the upper box body is connected with the lower box body through a bolt, the lower box body is arranged on a base, and the base is fixed on the protection hood through a bolt. The lower ends of two water inlet pipes penetrate through the protection hood and are connected to the nozzle body, the upper end of the screw rod is provided with a protection sleeve, and the protection sleeve is fixed on the upper box body through screws in a sleeved mode. The nozzle can be driven to move up and down by the worm, the worm wheel and the screw rod according to the shape of water sprayed by the nozzle, the distance between the nozzle and a steel plate to be cooled is adjusted, cooling evenness of the steel plate is improved, cooling capacity of a system is improved, and surface quality of the steel plate is improved.
Description
Technical field
The utility model belongs to rolling mill refrigerating mechanism field, relates in particular to a kind ofly for hot-rolled sheet strip steel, to roll rear cooling height-adjustable nozzle.
Background technology
Control cooling be by the cooling velocity after controlling hot rolled steel plate and rolling to reach the object of improving its tissue and performance, common are spray, aerosol, laminar flow, water curtain and the ultrafast type of cooling such as cold.Existing hot-rolled sheet strip steel rolls the mounting means that rear cooling jet adopts conventionally, is that nozzle and pressing plate are welded together, and is being fixed by bolts on protective cover.As disclosed in patent publication No. 99217245.4 " lengthening type atomized spraying nozzle " and number of patent application 200920128125.7 disclosed " a kind of aerosol nozzle for cooling of intermediate slab ", are all the fixing mounting means in position, so the height of nozzle distance steel plate to be cooled can not regulate.
Because nozzle distance cooling roller bed (steel plate to be cooled) highly immobilizes, while therefore using, just there is a problem: different because hot rolled steel plate rolls rear process for cooling, institute's water consumption is also not quite similar, if the flow of water is seldom time, from the current of nozzle ejection, there will be bifurcated, while being ejected on upper surface of steel plate to be cooled, can cause steel plate inhomogeneous cooling phenomenon.
Summary of the invention
The utility model aims to provide a kind ofly can adjust the distance between nozzle and steel plate to be cooled according to the water shape of ejection, thereby improves the cooling uniformity of steel plate, the height-adjustable nozzle of raising system cools ability.
For this reason, the solution that the utility model is taked is:
A height-adjustable nozzle, is characterized in that, nozzle, screw rod, protective cover, water inlet pipe, screw, protective sleeve, worm gear, worm screw, upper box, lower box, base, dome and bolt, consists of; In upper end of nozzle face center of gravity, a dome is fixed at place, the "T"-shaped head in screw rod lower end is movably connected in dome, screw rod upper end is connected in the bolt hole at worm gear center through protective cover and lower box, worm gear and worm engaging, worm gear and worm screw are fixed on upper box, upper box is bolted lower box, and lower box is installed on base, and base is bolted on above protective cover; Two water inlet pipe lower ends are connected on nozzle through protective cover, in the upper end of screw rod, are covered with protective sleeve, and protective sleeve is screwed on upper box.
The beneficial effects of the utility model are:
Because the utility model adopts the secondary transmission forming between worm gear and worm screw, worm gear bolt hole and screw rod secondary, can be according to the water shape of nozzle ejection, pass through rotary worm, drive worm gear and screw rod, and drive nozzle to move up and down under the guide function of two water inlet pipes, adjust the distance between nozzle and steel plate to be cooled, thereby guarantee the cooling uniformity of steel plate, improve system cools ability, and improve surface quality and the performance of steel plate.
Accompanying drawing explanation
Fig. 1 is height-adjustable nozzle arrangements schematic diagram.
In figure: nozzle 1, screw rod 2, protective cover 3, water inlet pipe 4, screw 5, protective sleeve 6, worm gear 7, upper box 8, connecting bolt 9, worm screw 10, lower box 11, base 12, set bolt 13, dome 14.
The specific embodiment
As seen from Figure 1, the height-adjustable nozzle of the utility model system is comprised of nozzle 1, screw rod 2, protective cover 3, water inlet pipe 4, screw 5, protective sleeve 6, worm gear 7, upper box 8, connecting bolt 9, worm screw 10, lower box 11, base 12, set bolt 13, dome 14.
Center of gravity place in nozzle 1 rectangle upper surface is fixed with a grooved dome 14, screw rod 2 lower ends are with "T"-shaped head, "T"-shaped head is movably connected in dome 14, and the upper end of screw rod 2 through after protective cover 3 and lower box 11, is threaded connection in the worm gear 7 tapped bolts hole in center successively.Worm gear 7 and worm screw 10 engaged transmission, worm gear 7 and worm screw 10 are fixed on upper box 8, upper box 8 connects lower boxes 11 by connecting bolt 9, lower box 11 is arranged on base 12, base 12 by set bolt 13 be fixed on protective cover 3 above.On nozzle 1, to be arranged with 4, two water inlet pipes 4 of two water inlet pipes spacing in the water pipe hole of protective cover 3 respectively in the left and right sides, and one is responsible for nozzle 1 and provides into water, and another limits guide function to having moved up and down of nozzle 1.For preventing that foreign matter from entering or clashing into screw rod 2, therefore in the upper end of screw rod 2, be also covered with protective sleeve 6, protective sleeve 6 is fixed on upper box 8 by screw 5.
