Problems solved by technology

[0012] The present invention aims at the above-mentioned problems such as the dismantling of many people, difficult operation, high requirements for dismantling tools, personnel and operating space, and provides a front-inserted upper nozzle dismantling device, which solves the problems of too long time for dismantling the upper nozzle and too many people. , the key technology of the dismantling device of the present invention is that it can be inserted from the bottom of the upper nozzle (mechanism side), and then the device slider flap is opened to pull the upper end of the upper nozzle, and then the distance between the oil cylinders is locked to improve the effectiveness of the oil cylinder as much as possible. In the working stroke, another worker operates the hydraulic station to drive the cylinder to pull down the upper water port

Embodiment 1

[0034] to combine figure 1 and figure 2 It can be seen that the front plug-in type upper nozzle disassembly device of the present invention includes a double-rod hydraulic cylinder 1, a piston rod I2, a piston rod II12 and a pull rod 71. The double-rod hydraulic cylinder 1 is a hollow structure. The limit plate 3 is fixed at the end of the piston rod I2; the tie rod 71 runs through the double-rod hydraulic cylinder 1 and the limit plate 3, and the piston rod II12 is fixedly connected with the pull rod 71 through the piston rod protection head 8; the tie rod 71 is close to the limit plate 3 The end of one end of the pull rod is a pull rod head 7, and the pull rod head 7 is provided with a hollow groove, and a flap 6 is fixed in the hollow groove through a rotating shaft 5, and a limit hole 9 is arranged on the rod body at the other end of the pull rod, and the limit hole is matched with the limit hole. pin 91.

[0035] The end of the piston rod I2 fixes the limit plate 3 thr...

Embodiment 2

[0038] In this embodiment, the hydraulic station is attached to the device, which can also be used when there is no hydraulic station in the operation site, and also includes a small mobile hydraulic station 11. Station connection, the hydraulic system is provided with a hydraulic operation panel, and a height adjustment rod 13 can also be provided to meet the needs of different situations and facilitate operation.

[0039] All the other technical features are the same as in Embodiment 1.

[0040] image 3 The reference diagram showing the use state of the device of the present invention shows that the front-inserted upper nozzle removal device, when in use, the operator stands on the side of the mechanism at the bottom of the ladle, extends the pull rod head 7 from the upper nozzle hole into the ladle, and rotates The pull rod 71 and the flap 6 rotate along the rotating shaft. The operator pulls the pull rod 71 outward. The flap is pushed against the upper edge of the upper ...

Abstract

The invention belongs to the technical field of steel-ladle upper nozzle disassembling equipment, and particularly relates to a front insertion type upper nozzle disassembling device. According to the key technology, the disassembling device can be inserted from the bottom of an upper nozzle (the mechanism side), and a turning plate of a pull head of the device is opened and holds the upper end of the upper nozzle, and then locks an oil cylinder for increasing the effective working stroke of the oil cylinder as much as possible; and another worker operates a hydraulic station to drive the oil cylinder to pull down the upper nozzle.

Description

technical field [0001] The invention belongs to the technical field of ladle upper nozzle dismantling equipment, in particular to a front insertion type upper nozzle dismantling device. Background technique [0002] Replacing the upper nozzle is the most labor-intensive job in the ladle hot repair section of the steelmaking plant. Especially in summer, the working environment for workers is even worse. At present, some steel mills have adopted tooling to dismantle the used upper nozzle, but the effect is not ideal. [0003] At present, the disassembly of the upper nozzle is mainly to use a pick to break the upper nozzle whose service life has expired, and then remove and clean this traditional method, which takes a long time and causes great damage to the seat brick, which affects the online service life of the ladle. , workers need to work at close range, the operating environment is harsh, and the labor intensity of workers is high. In terms of the number of hot repair per...
