Abstract
The utility model discloses a ladle nozzle automatic pulling-out device, which belongs to the technical field of casting, and comprises a hydraulic cylinder, a cylindrical top sleeve, a cylindrical water pulling-out nozzle joint and a water pulling-out nozzle pull rod, wherein the cylindrical top sleeve is coaxially sleeved outside a piston rod of the hydraulic cylinder and is fixedly connected with a cylinder body of the hydraulic cylinder through a flange, the water pulling-out nozzle pull rod and the hydraulic cylinder are coaxially arranged, a chuck is arranged on one end of the water pulling-out nozzle pull rod relative to the piston rod of the hydraulic cylinder, a shoulder is arranged on the other of the water pulling-out nozzle pull rod, one end of the cylindrical water pulling-out nozzle joint is arranged relative to the piston rod of the hydraulic cylinder through threads, and a neck which is matched with the chuck which is arranged on the end portion of the water pulling-out nozzle pull rod is arranged on the other end of the cylindrical water pulling-out nozzle joint. The ladle nozzle automatic pulling-out device connects a ladle nozzle and the piston rod of the hydraulic cylinder together by utilizing the water pulling-out nozzle pull rod and the cylindrical water pulling-out nozzle joint, and pulls out the ladle nozzle by utilizing the hydraulic cylinder to drive the water pulling-out nozzle pull rod, thereby greatly reducing labor strength of workers, reducing take-down time of the ladle nozzle, and improving turnover efficiency of a ladle.
Description
Technical field
The utility model relates to a kind ofly can extract the device of filling pipe end to be replaced on the ladle fast in the situation that do not destroy ladle pocket block, belongs to casting technology field.
Background technology
Steel ladle sliding water gap is an important device of molten steel flow in the control ladle, mainly comprises filling pipe end, upper slide, lower skateboard and the lower mouth of a river (referring to Fig. 1), and its operation principle is by making the upper lower skateboard changing of the relative positions regulate the size of molten steel flow.Ladle in use often need to be changed slide gate nozzle, and the upper slide of slide gate nozzle, lower skateboard and lower mouth of a river ratio are easier to remove, and filling pipe end closely links together by bonding agent and ladle pocket block, removes relatively difficulty.Owing to also there not being special-purpose filling pipe end detaching device at present, the mode that the filling pipe end that exceeded standard by molten steel erosion hole enlargement can only adopt artificial chisel to hit is carried out destructiveness and is removed, so not only increased workman's labour intensity, and the time spent is longer, greatly reduces all transfer efficients of ladle.
The utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of ladle upper nozzle automatic extracting apparatus, to reduce workman's labour intensity, improves all transfer efficients of ladle.
The alleged problem of the utility model realizes with following technical proposals:
The automatic extracting apparatus of a kind of ladle upper nozzle comprises hydraulic cylinder, cylindric top cover, cylindricly pulls out water outlet connector and pull out mouth of a river pull bar in the formation, described top cover coaxial package is outside and affixed by the cylinder body of flange and hydraulic cylinder at the piston rod of hydraulic cylinder; Described to pull out mouth of a river pull bar coaxial with hydraulic cylinder, and its end relative with the piston rod of hydraulic cylinder is provided with chuck, and the other end is provided with shoulder block, behind the shoulder block for putting in the long-armed bar that ladle is used; A described end that pulls out water outlet connector docks with the piston rod of hydraulic cylinder by screw thread, and the other end is provided with the draw-in groove that is complementary with the chuck that pulls out mouth of a river tie rod end.
The automatic extracting apparatus of above-mentioned ladle upper nozzle, also comprise cantilever crane in the formation, described cantilever crane comprises cantilever crane support and electric hoisting dolly, described electric hoisting dolly is installed on the horizontal rail on the cantilever crane support, and the steel wire rope binding on its crampon is on the suspension ring of hydraulic cylinder and top cover.
The utility model utilization is pulled out mouth of a river pull bar and is pulled out water outlet connector the piston rod of ladle upper nozzle and hydraulic cylinder is linked together, utilizing Driven by Hydraulic Cylinder to pull out mouth of a river pull bar extracts the filling pipe end of ladle, greatly reduce workman's labour intensity, shorten the take-down time of filling pipe end, improved all transfer efficients of ladle.

The specific embodiment
Referring to Fig. 2～Fig. 8, the utility model mainly comprises hydraulic cylinder 9, the top cover that is connected with hydraulic cylinder 9 10 and pull out water outlet connector 14, be used for cantilever crane, the tension filling pipe end 2 of mobile hydraulic cylinder 9 and pull out water outlet connector 14 pull out mouth of a river pull bar 15, Hydraulic Station and control system.
The course of work of this device is: will pull out the mode that water outlet connector 14 is threaded connection and be fixed on the piston rod of hydraulic cylinder 9, operation cantilever crane mobile hydraulic cylinder 9 and top cover 10, make top cover 10 withstand ladle outer wall 6, the operative employee uses steel pipe greater than the ladle height to entangle drag link sleeve axle 18 will to pull out mouth of a river pull bar 15 and pass filling pipe end 2 and will pull out mouth of a river pull bar 15 and pull out water outlet connector 14 with an end of chuck 13 and link together by chuck 13 and draw-in groove 11 from ladle is suitable for reading, the shoulder block 12 that pulls out on the mouth of a river pull bar 15 leans against the side that filling pipe end 2 is positioned at ladle, and operation hydraulic cylinder 9 is intactly slowly extracted filling pipe end.
This device is easy to operate, has greatly alleviated labor strength, has avoided the environmental pollution that causes in the operation.When using this device to remove filling pipe end, the activity duration reduced to 3 minutes by original about 10 minutes, improved all transfer efficients of ladle.
