Abstract

The utility model discloses a movable overflow tank trolley which comprises two movable trolleys and a driving mechanism, wherein overflow tanks are arranged on the movable trolleys, and the driving mechanism drives the two movable trolleys to synchronously move so that the overflow tank on any movable trolley can move to or move out from the position below an overflow port of a tundish. The utility model provides a movable overflow tank trolley capable of replacing an overflow tank during continuous casting.

Description

Portable overflow tank dolly

Technical Field

The utility model relates to the field of continuous casting equipment. More particularly, the present utility model relates to a mobile overflow tank cart.

Background

Overflow tanks used on existing caster platforms typically receive a small amount of molten steel at the beginning of casting, between the tundish and the turret. The overflow tank can not only accept the overflow of the tundish, but also accept the molten steel flowing out of the swinging groove at the bottom of the tundish. After the overflow tank is full, it needs to be quickly replaced. At present, when the overflow tank is replaced, the overflow tank is transferred in a hoisting mode, but because the overflow tank is arranged below a large ladle turret, a ladle above the middle tank needs to be removed during hoisting, and then the overflow tank is hoisted. Therefore, when continuous casting is performed, the overflow tank can not be replaced in time after the overflow tank is filled, and the overflow tank can be replaced after casting is stopped, so that the efficiency of continuous casting operation is affected.

Disclosure of Invention

The utility model aims to provide a movable overflow tank trolley capable of replacing an overflow tank during continuous casting.

The technical scheme for solving the technical problems is as follows: the utility model provides a portable overflow tank dolly, includes two travelling wagons and actuating mechanism, all be equipped with the overflow tank on the travelling wagons, actuating mechanism drives two travelling wagons synchronous motion, so that arbitrary overflow tank on the travelling wagons can be moved to the tundish overflow mouth below or shift out from the tundish overflow mouth below.

Preferably, in the mobile overflow tank trolley, the driving mechanism comprises a linear rail and two driving units, the two mobile trolleys are slidably arranged on the linear rail, one ends of the two mobile trolleys, which are close to each other, are connected, and the two driving units are respectively arranged at two ends of the linear rail and are respectively in transmission connection with the two mobile trolleys.

Preferably, in the mobile overflow tank trolley, the driving unit is a winch, and a steel rope of the winch is connected with the corresponding mobile trolley.

Preferably, in the mobile overflow tank trolley, two ends, away from each other, of the mobile trolley are respectively provided with a proximity switch, two ends of the rail are respectively provided with a limiting plate corresponding to the two proximity switches, and the limiting plates are provided with sensing surfaces corresponding to the proximity switches.

According to the movable overflow tank trolley, the two movable trolleys are driven to synchronously move through the driving mechanism, so that one overflow tank on the two movable trolleys is selectively moved to molten steel connected below an overflow port of the tundish, and meanwhile, the overflow tank on the other movable trolley can be lifted, and therefore the overflow tank can be replaced during continuous casting.

Additional advantages, objects, and features of the utility model will be set forth in part in the description which follows and in part will become apparent to those having ordinary skill in the art upon examination of the following or may be learned from practice of the utility model.

Detailed Description

The present utility model is described in further detail below with reference to the drawings to enable those skilled in the art to practice the utility model by referring to the description.

It should be noted that, in the description of the present utility model, the terms "transverse", "longitudinal", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, merely for convenience in describing the present utility model and simplifying the description, and do not indicate or imply that the apparatus or elements referred to must have a specific orientation, be configured and operated in a specific orientation, and thus should not be construed as limiting the present utility model.

Fig. 1-2 are diagrams of a mobile overflow tank trolley provided by an embodiment of the utility model, which comprises two mobile trolleys 1 and a driving mechanism, wherein overflow tanks 2 are arranged on the mobile trolleys 1, and the driving mechanism drives the two mobile trolleys 1 to synchronously move so that the overflow tank 2 on any mobile trolley 1 can move to or from the lower part of an overflow port of a tundish.

In this embodiment, the driving mechanism drives the two travelling wagons 1 to move synchronously, so that one of the overflow tanks 2 on the two travelling wagons 1 moves to molten steel connected below the overflow port of the tundish, at this time, the overflow tank 2 on the other travelling wagons 1 moves to the outer side below the ladle turret, at this time, the overflow tank 2 on the other travelling wagons 1 can be lifted, in this embodiment, the two overflow tanks 2 are fixed by the two travelling wagons 1, and the two overflow tanks 2 are used alternately, thereby realizing the replacement of the overflow tank 2 during continuous casting.

Preferably, as another embodiment of the present utility model, the driving mechanism includes a linear rail 3 and two driving units, both of the two travelling carriages 1 are slidably disposed on the linear rail 3, one ends of the two travelling carriages are connected to each other, and the two driving units are disposed at two ends of the linear rail 3 and are in transmission connection with the two travelling carriages 1, respectively.

In this embodiment, as one specific implementation method, the driving unit is a winch 4, a steel rope of the winch 4 is connected with the corresponding travelling car 1, when one travelling car 1 needs to be moved out from the lower part of the overflow port of the tundish, the winch 4 close to the travelling car 1 is wound, and the winch 4 far from the travelling car 1 is unwound, so that the travelling car 1 is pulled out from the lower part of the overflow port of the tundish, and the other travelling car 1 is pulled out from the lower part of the overflow port of the tundish.

Preferably, as another embodiment of the present utility model, proximity switches 5 are respectively disposed at one ends of the two moving trolleys 1 away from each other, two limiting plates 6 corresponding to the two proximity switches 5 are respectively disposed at two ends of the track, and sensing surfaces corresponding to the proximity switches 5 are disposed on the limiting plates 6.

In this embodiment, in order to prevent the moving trolley 1 from moving excessively, limiting plates 6 are respectively arranged at two ends of the track, then proximity switches 5 are arranged on the two moving trolleys 1, and the proximity switches 5 are connected to a control circuit of the moving trolley 1, when any moving trolley 1 moves to a limit position, the proximity switch 5 on the control circuit senses the sensing surface of the corresponding limiting plate 6, so that the driving unit stops working.

Although embodiments of the present utility model have been disclosed above, it is not limited to the details and embodiments shown, it is well suited to various fields of use for which the utility model is suited, and further modifications may be readily made by one skilled in the art, and the utility model is therefore not to be limited to the particular details and examples shown and described herein, without departing from the general concepts defined by the claims and the equivalents thereof.
