Abstract
The utility model relates to a novel ladle nozzle opening and closing device, which mainly consists a fixing plate, a front clamp plate, a rear clamp plate, a mounting hole, an oil cylinder push rod, a hydraulic oil cylinder, an oil cylinder fixing groove and a fastening slot, wherein the front clamp plate and the rear clamp plate are connected with the fixing plate, the mounting hole is arranged on the front clamp plate, the oil cylinder push rod is arranged between the rear clamp plate and the front clamp plate, the hydraulic oil cylinder is connected with the oil cylinder push rod, and the fastening slot is arranged on the oil cylinder push rod. The novel ladle nozzle opening and closing device is characterized in that the mounting hole on the front clamp plate is convex. The access position for mounting the head of the oil cylinder push rod is fixed and the size of the rest part of the mounting hole is reduced so that the oil cylinder push rod cannot fall off the mounting hole and reliability thereof is improved. Accidents that steel is discharged from a seat tank or the oil cylinder push rod falls off when the oil cylinder push rod is moved due to misoperation of hot-repair operators are avoided, and further, the oil cylinder push rod is easy to be lubricated, motion resistance of the oil cylinder push rod is reduced and the service life thereof is prolonged since the contact area of the oil cylinder push rod is reduced during sliding.
Description
Technical field
The utility model relates to steelmaking equipment, specifically belongs to the ladle nozzle opening and closing device.
Background technology
The molten steel jar is the imperative equipment of transhipment molten steel in the steel manufacture process.Mouth of a river opening and closing device be molten steel from steel ladle pouring to the key component of Baogang, the security relationship of its use is to the safety in production of ladle.
In hot repair production operation process, find under the state that slide plate is opened, still can oil cylinder be unloaded, not following jar of accident potential that receives steel of closed condition of slide plate takes place because of negligence of operation in existence; In addition, the oil cylinder hydraulic piston rod is prone to produce the phenomenon that drops in opening or closing process, through investigation and analysis, and the reason that it produces for problem:
1, because the load hole total length on the front plate is wide shape; The width dimensions in hole is greater than the push rod head diameter; In the length range in hole; The oil cylinder hydraulic piston rod all can advance to go out, and is difficult to guarantee that slide plate is in closed condition when seat jar receives steel, exists slide plate not close and seat jar tapping, oil cylinder are dropped in opening or closing the skateboarding process and caused accident potential such as big bag slide plate is out of control.
2, because cylinder putter and push rod chute wall contact area are big, cause the push rod slideway resistance of motion big, and be difficult for lubricating, have when moving by the card phenomenon so exist.
The utility model content
The purpose of the utility model is to solve the deficiency of present existence, provides a kind of and can prevent that cylinder putter from dropping, and can reduce its cylinder putter resistance of motion, eliminates the ladle nozzle opening and closing device of the potential safety hazard that causes thus.
Realize the technical measures of above-mentioned purpose:
New steel water-coating port opening and closing device; Mainly be made up of the draw-in groove on the cylinder putter between the load hole on fixed head, the front plate that is connected with fixed head and rear plate, the front plate, rear plate and the front plate, the hydraulic jack that is connected with cylinder putter, oil cylinder holddown groove, the cylinder putter, it is: the load hole on the front plate is a convex.
It is characterized in that: top and both sides on the cylinder putter surface are respectively equipped with the drag reduction groove.
The utility model compared with prior art; Fix because the turnover position of push rod head will be installed, reduce the remainder size in hole, cause to drop its load hole from front plate; Thereby improved the reliability of cylinder putter operation; Guaranteed that from equipment push rod opens the continuity the motion at the mouth of a river, avoided hot repair personnel's careless maloperation, made push rod drop by tapping of seat jar or cylinder putter under the situation and cause accident opening; Owing to reduced the contact area of cylinder putter in sliding process, make it easy to lubricate, and reduce its resistance of motion, help the increase of its life cycle.
Description of drawings
Fig. 1 is the structural representation of new steel water-coating port opening and closing device
Fig. 2 is the cross section structure sketch map of cylinder putter among Fig. 1
Among the figure: 1-fixed head, 2-front plate, 3-rear plate, 4-load hole, 5-cylinder putter, 6-hydraulic jack, 7-oil cylinder holddown groove, 8-draw-in groove, 9-drag reduction groove.
The specific embodiment
Do below in conjunction with accompanying drawing and to further describe:
New steel water-coating port opening and closing device mainly is made up of the draw-in groove 8 on the cylinder putter 5 between the load hole 4 on fixed head 1, the front plate 2 that is connected with fixed head 1 and rear plate 3, the front plate 2, rear plate 3 and the front plate, the hydraulic jack 6 that is connected with cylinder putter 5, oil cylinder holddown groove 7, the cylinder putter 5.It is processed as convex with the load hole on the front plate 24; When cylinder putter 5 is in when closing, draw-in groove 8 and feed in the stub end of convex load hole 4 head of the piston rod of oil cylinder hydraulic 6 in the stub end of convex load hole 4.
In order to reduce the resistance of motion of cylinder putter 5, process drag reduction groove 9 respectively in the top and the both sides on its cylinder putter 5 surfaces.
This embodiment is merely and gives an example.
Claims (2)
1. new steel water-coating port opening and closing device; Mainly be made up of the draw-in groove on the cylinder putter between the load hole on fixed head, the front plate that is connected with fixed head and rear plate, the front plate, rear plate and the front plate, the hydraulic jack that is connected with cylinder putter, oil cylinder holddown groove, the cylinder putter, it is characterized in that: the load hole on the front plate is a convex.
2. new steel water-coating port opening and closing device as claimed in claim 1 is characterized in that: top and both sides on the cylinder putter surface are respectively equipped with the drag reduction groove.
