Abstract

The utility model relates to a stopper control device of a conticaster pouring box to control the molten steel flow, and control ways of the device are hand control and electric control. The installation of an electric cylinder of the device is simple and rapid, and a duckbill-shaped connecting piece (7) at the upper end of the electric cylinder (8) is rapidly jointed with a rotating axle (6) in a connection guiding device (5). Through the rotation of a hand handle (17), the close connection can be realized. When hand operation is carried out, a function lever (11) is depressed and uplifted, a dead axle of a bent axle (10) rotates, causing a bearing (18) at the other end of the bent axle (10) to roll in a lifting guide groove (9) and causing the lifting guide groove (9) to move up and down, thereby driving a lifting axle (3) to move up and down. The structure does not generate horizontal force component and reduces the friction of the lifting axle (3) and an axle sleeve (4), and the stopper control device has the advantages of labor saving, flexible operation and long service life.

Description

The stopper control device

Technical field

The utility model relates to a kind of stopper control device of controlling conticaster tundish steel flow outflow.

Background technology

At present, conticaster tundish stopper control device has two kinds of design forms, the one, side-mounted, be left side or the right side that electronic cylinder is installed in lifting shaft, adopt fixed installation, the necessary electronic cylinder of supporting installation of every suit mechanism, cost is than higher, and electronic cylinder is installed in the control accuracy of the side effect stopper of lifting shaft.Another kind is positive formula, it is the front that electronic cylinder is installed in lifting shaft, adopt the Fast Installation mode, reduced the usage quantity of electronic cylinder, but employing at present is the mode that installs and fixes of upper and lower bearing pin basically, electronic cylinder must insert upper pin in the fixing hole in vertical direction with miter angle when installing, change miter angle and be vertical direction, fix fixed pin shaft under the electronic cylinder again, installation is wasted time and energy, and is difficult to reach the effect of Fast Installation.

The transmission of the manual control of these two kinds of stopper mechanisms design simultaneously all is to adopt the rack-and-pinion mode, when manual operation, can produce the power of a horizontal direction, increase the frictional force of lifting shaft and upper and lower axle sleeve, influence is the flexibility of control manually, and operation is effort relatively.

Summary of the invention

Install and waste time and energy and manually control inflexible shortcoming in order to overcome the electronic cylinder of current conticaster tundish stopper control device, the utility model provides a kind of stopper control device, this control device can reach electronic cylinder Fast Installation, reduces cost, and improves the purpose of stopper control accuracy; More flexible laborsaving during manual operation.

The technical scheme that the utility model adopted is: the stopper control device comprises stopper, crossbeam, is loaded on the lifting shaft in the casing, the lower end of casing is provided with down mount pad, lifting shaft top is installed and is connected guider, in be provided with rotating shaft, the duck of electronic cylinder by the upper end chews the shape connector and is connected with rotating shaft, and duck chews the gradient opening of shape connector.The rotating shaft middle part is milled with planar section, in its end handle is housed, and by handle, the rotating shaft rotation reaches tight connection.Make the arc surface of rotating shaft and duck chew shape connector inner hole surface and reach interference fit, promptly finish top and install.

In manual control structure, the lifting guide groove is installed on the lifting shaft bottom, bent axle is fixed in casing one side by bearing block, the groove that bearing one end is arranged in the lifting guide groove is housed in the bent axle, at the other end action bars is installed, when pressing and lift action bars, the bent axle dead axle rotates, the bearing of bent axle one end rolls in guide groove, drives lifting shaft simultaneously and moves up and down.

The beneficial effects of the utility model are:

1) realize electronic cylinder Fast Installation, time saving and energy saving;

2) manually control flexiblely, reduce friction, increase the service life axle sleeve.

Description of drawings:

Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described further.

Fig. 1 is the structural representation of the utility model specific embodiment;

Fig. 2 is that A among Fig. 1 is to connecting the guider schematic diagram;

Fig. 3 chews the shape connector schematic diagram that combines with the rotating shaft planar section for duck;

Fig. 4 chews shape connector and the tight connection diagram of rotating shaft arc surface for duck;

Fig. 6 is that C among Fig. 5 is to view.

Among the figure: 1, stopper, 2, crossbeam, 3, lifting shaft, 4, axle sleeve, 5, connect guider, 6, rotating shaft, 7, duck chews the shape connector, 8, electronic cylinder, 9, the lifting guide groove, 10, bent axle, 11, manual lever, 12, installation shaft under the electronic cylinder, 13, mount pad down, 14, casing, 15, guide plate, 16, guide wheel, 17, handle, 18, bearing, 19, install bin side bearing block.

The specific embodiment

Electronic cylinder upper end Fast Installation such as Fig. 1～shown in Figure 4, lifting shaft 3 makes crossbeam 2 and stopper 1 make corresponding mobile when moving up and down, and when automatic, lifting shaft is driven by electronic cylinder, moves up and down.Installation shaft 12 is advanced in the following mount pad 13 of casing 14 bottoms under the electronic cylinder, as the strong point of electronic cylinder motion.The top of lifting shaft is equipped with and connects guider 5, and rotating shaft 6 wherein is housed, and it can have in the middle of the rotating shaft and mill flat planar section by handle 17 rotations.Electronic cylinder upper end is equipped with duck and chews connector 7, duck chews the opening that shape connector 7 has gradient, promotes electronic cylinder 8, makes duck chew the planar section that shape connector 7 is easy to enter into rotating shaft 6, realize that duck chews the shape connector and is connected with rotating shaft, advance also to be close to, make rotating shaft 6 half-twists by handle 17, arc surface and duck chew shape connector 7 and reach and closely cooperate in the rotating shaft 6, and interference arranged, i.e. upper end installation is so just finished electronic cylinder and is installed immediately at the scene, and its installation is accomplished quick and convenient.

New-type hand gear is by the lifting guide groove 9 that is installed on the lifting shaft bottom, bent axle 10, bent axle is positioned on the casing side by the bearing block 19 that is installed on the casing side, as the standard shaft that rotates, one end of bent axle is equipped with rolling bearing 18, and it matches with the slotted eye of lifting guide groove.The other end is equipped with manual lever 11, and action bars can load and unload fast.When depressing or lift action bars, bent axle will rotate in fixed axis, when its bearing 18 is rolled along the lifting guide groove, lifting shaft is risen or decline, in whole process, do not produce lifting shaft 3 horizontal (level) component, the friction of lifting shaft and bearing holder (housing, cover) is little, makes easy to operately, increases the service life.

Though described embodiment of the present utility model in conjunction with the accompanying drawings, those of ordinary skill in the art can make various distortion or modification in the scope of described claim.
