Technical field
The utility model belongs to the locking and unlocking mechanism when producing seamless steel pipe, is specifically related to a kind of seamless steel pipe three-roll hot-rolling mill locking and unlocking mechanism.
Background technology
At present, the construction of the sustained, stable growth of China's economic and Development of China's Urbanization in recent years and infrastructure has promoted the health of steel industry, quick and stable development.Seamless steel pipe is widely used in industry-by-industry as raw material, and the level of production of seamless steel pipe also becomes an important indicator of weighing iron and steel production level.The three-roll hot-rolling mill of using in the seamless steel tube production at present adopts overall structure mostly, and adjustment and maintenance for equipment in actual production are very inconvenient.
Summary of the invention
The purpose of the utility model is to solve adjustment that exists in the three-roll hot-rolling mill production process in the prior art and the problem of safeguarding inconvenience, and a kind of seamless steel pipe three-roll hot-rolling mill locking and unlocking mechanism is provided.
The technical scheme of the utility model is achieved in that a kind of seamless steel pipe three-roll hot-rolling mill locking and unlocking mechanism; Comprise gantry base, be arranged on gantry base top lower bearing bracket, cooperate and to be installed in the upper spider on lower bearing bracket top and to be installed on the upper and lower frame and the roll of corresponding cooperation; Upper spider is connected with the rotary pin shaft hinge of lower bearing bracket through the one of which side, is separately installed with locking cylinder at the four corners position of gantry base, said locking cylinder upper end with lock connecting lever and be connected; This locking connecting lever hinge is connected the corresponding site of lower bearing bracket; Upper spider is provided with and the upper spider locking bed of locking the corresponding cooperation of connecting lever, is provided with the relay oil cylinder in the side with rotary pin shaft, and gantry base is provided with the unlatching oil cylinder; This unlatching oil cylinder one end is connected with gantry base, and the other end is connected with upper spider.
When this unlatching oil cylinder was opened to certain angle, the relay oil cylinder stretched out and cooperates and supports upper spider, shrinks through the relay oil cylinder, makes upper spider reach the enable possition.
The good effect of the utility model: this mechanism of the utility model is used for seamless steel pipe three-roll hot-rolling mill locking and unlocking mechanism; Be an exclusive locking and unlocking mechanism that cooperates the seamless steel pipe three-roll hot-rolling mill to use, can accomplish the locking and the unlatching work of three-roll hot-rolling mill.
Description of drawings
Fig. 1 is the front view of the utility model three-roll hot-rolling mill opening.
Fig. 2 is the front view of the utility model three-roll hot-rolling mill locking state.
Among the figure: 1 gantry base, 2 open oil cylinder, 3 lower bearing brackets, 4 locking cylinders, 5 locking connecting levers, 6 rotary pin shafts, 7 upper spider locking beds, 8 upper spiders, 9 rolls, 10 relay oil cylinders.
The specific embodiment
Embodiment: like Fig. 1, shown in 2; Following based on this seamless steel pipe three-roll hot-rolling mill locking and unlocking mechanism practical implementation of the present invention: this seamless steel pipe three-roll hot-rolling mill locking and unlocking mechanism comprises gantry base 1, is arranged on the lower bearing bracket 3 on gantry base 1 top, cooperate and be installed in the upper spider 8 on lower bearing bracket 3 tops and be installed on upper spider, the lower bearing bracket and the roll 9 of corresponding cooperation; Upper spider 8 is connected with rotary pin shaft 6 hinges of lower bearing bracket 3 through the one of which side; Have rotary pin shaft 6 one sides and be provided with relay oil cylinder 10 said; Gantry base 1 is provided with opens oil cylinder 2; These unlatching oil cylinder 2 one ends are connected with gantry base 1, and the other end is connected with upper spider 8, are provided with locking device at upper spider 8 and 3 of lower bearing brackets.
Described locking device comprises the locking cylinder 4 that is installed on the gantry base 1; Said locking cylinder 4 upper ends are connected with locking connecting lever 5; These locking connecting lever 5 hinges are connected the corresponding site of lower bearing bracket 3; Upper spider 8 is provided with and the upper spider locking bed 7 of locking connecting lever 5 corresponding cooperations, and this locking connecting lever 5 is arranged on the upper spider locking bed 7 during locking.
Locking cylinder 4 lower ends are connected on the three-roll hot-rolling mill gantry base 1, and the upper end links to each other with locking connecting lever 5, and locking connecting lever 5 is fixed in the corresponding site of three-roll hot-rolling mill lower bearing bracket 3, and the lower end of locking connecting lever links to each other with locking cylinder 4; Three-roll hot-rolling mill upper spider 8 links together through rotary pin shaft 6 and three-roll hot-rolling mill lower bearing bracket 3; Opening oil cylinder 2 one ends is connected with three-roll hot-rolling mill gantry base 1; The other end links to each other with three-roll hot-rolling mill upper spider 8; When unlatching oil cylinder 2 is opened with 10 elongations of relay oil cylinder; Relay oil cylinder 10 is connected with upper spider 8, and this mechanism is used for the seamless steel pipe three-roll hot-rolling mill, can accomplish the locking and the unlatching work of three-roll hot-rolling mill.
Its groundwork process is following: locking: under the effect of locking cylinder 4 elongations, the other end of locking connecting lever 5 moves on upper spider locking bed 7 positions, fixes 8, four fixing points of three-roll hot-rolling mill upper spider and plays the locking effect.
Open: under the effect of locking cylinder 4 compressions; 5 motions of locking connecting lever break away from upper spider locking bed 7; Open oil cylinder 2 elongations simultaneously; Three-roll hot-rolling mill upper spider 8 is opened to certain position under 2 effects of unlatching oil cylinder, when 10 elongations of relay oil cylinder, be connected with upper spider 8, plays the unlatching effect through 10 compressions of relay oil cylinder.
Although the invention is set forth, it should be appreciated by those skilled in the art that and to carry out various modifications and distortion and not break away from its scope to the invention with reference to preferred embodiment.
