Abstract
The utility model provides a sliding pressing mechanism for a sliding water port. The sliding pressing mechanism comprises a track and a track wheel matched with the track. The track is formed by a slope and a plane connected with the slope, the slope is located at one end of the track, the track wheel is installed at the end of a wheel shaft, the wheel shaft is connected with a support, and the cross section of the track wheel is in a regular polygon shape. By means of the structural style, on one hand, the track wheel and the track form surface contact so that pressure between the track wheel and the track is stable and is not subjected to influence of mixed sundries easily; on the other hand, after the sliding pressing mechanism is used for a certain times, abrasion conditions of the working surface of the track wheel can be detected through a detection device, the contact surface between the track wheel and the track is replaced when the track wheel is at a low position, so that the service life of the track wheel is effectively prolonged, and the steel-making cost is reduced.
Description
Technical field
The utility model relates to a kind of slide gate nozzle, especially a kind of slide gate nozzle slip pressure exerting arrangement.
Background technology
At present, sliding nozzle device both domestic and external mostly is elastic mechanism, and the mode of its face press contacts is divided into the plane contact mode of track matching track and the line way of contact of roller matching track.Wherein, in the way of contact of track matching track, mechanism will adopt side to open the door usually, presses bolt to compress by clamping sides or face, its advantage is that face press contacts mode is the face contact, face is pressed stable, has guaranteed the security of mechanism, and shortcoming is complicated operation, contact area between two orbit planes is large, cause the track rate of wear fast, service life is short, thereby has improved steel-making cost; In the way of contact of pair of rollers track, " climbing " that can be by roller be generation face pressure automatically, its advantage is simple to operate, the rolling of the line way of contact and roller makes the frictional force between roller and the track less, has prolonged the service life of parts, shortcoming is the impact that this kind way of contact is subjected to field trash easily, add upper rail and roller under long-time high temperature action, local deformation occurs easily, cause face to press unbalance and cause security incident.The existing weak point of prior art that Here it is.
Summary of the invention
The technical problems to be solved in the utility model is exactly for the existing deficiency of prior art, and a kind of slide gate nozzle slip pressure exerting arrangement of pressing stable and long service life is provided.
This programme is achieved by the following technical measures: this slide gate nozzle comprises that with the slip pressure exerting arrangement end is the track on slope and the rail wheel that cooperates with track, and rail wheel is installed on the end of wheel shaft, and the cross section of described rail wheel is regular polygon.
In order to reach better result of use, above-mentioned regular polygon adopts square, regular pentagon, regular hexagon, positive heptagon or octagon.
The beneficial effect of this programme can be learnt according to the narration to such scheme, this slide gate nozzle is with in the slip pressure exerting arrangement, the cross section of described rail wheel is regular polygon, this version, on the one hand rail wheel is contacted with track formation face, thereby make pressure stability between the two not be subject to the field trash impact, on the other hand, after mechanism uses certain number of times, can detect by checkout gear the abrasion condition of rail wheel working face, and when rail wheel is in low level, change the contact-making surface of itself and track, thus effectively prolonged the service life of rail wheel, reduced steel-making cost.This shows that the utility model compared with prior art has substantive distinguishing features and progress, the beneficial effect of its enforcement also is apparent.
Description of drawings
Fig. 1 is the structural representation of the utility model specific embodiment.
Among the figure, 1 is track, and 2 is rail wheel, and 3 is wheel shaft.
The specific embodiment
For clearly demonstrating the technical characterstic of this programme, below by the specific embodiment, and in conjunction with its accompanying drawing, this programme is set forth.
A kind of slide gate nozzle slip pressure exerting arrangement, as shown in Figure 1, it comprises track 1 and the rail wheel 2 that cooperates with track 1, track 1 reaches the plane that links to each other with the slope by the slope and consists of, the slope is positioned at an end of track 1, and rail wheel 2 is installed on the end of wheel shaft 3, and wheel shaft 3 links to each other with support, the cross section of described rail wheel 2 is regular polygon, can adopt square, regular pentagon, regular hexagon, positive heptagon or octagon according to concrete needs.
When mechanism works, hydraulic means drive track wheel 2 moves along track 1, make a face of rail wheel 2 produce relative fricting movement with track 1, and rail wheel 2 can rotate around wheel shaft 3, when rail wheel 2 contacts with the slope of track 1, rail wheel 2 can rotate around wheel shaft 3, and a face of rail wheel 2 is contacted with track 1 close contact and formation face all the time, produces stable face and presses.
Face of rail wheel 2 can detect by checkout gear the abrasion condition of this working face after using certain number of times, and changes itself and the contact-making surface of track 1 when rail wheel 2 is in low level, takes turns for 2 service life with advancing the track.
Can pass through existing techniques in realizing without the technical characterictic of describing in the utility model, not repeat them here.
