Technical Field

The invention relates to the field of tundish tipping equipment, in particular to a tundish tipping device.

Background

After a certain number of furnaces are poured into the tundish, the residual slag blocks such as cold steel, refractory bricks and the like in the tundish must be poured out by using a tundish tipping device. The prior tundish tilting device generally comprises a processing chamber and a tilting machine, wherein the processing chamber is provided with at least one tilting pit, the top of each tilting pit is provided with an inlet, the tilting machine is assembled in the processing chamber, and the side surface of each tilting pit is provided with an outlet. Firstly, the tundish is put into the tipping machine from the inlet through a crane and is installed on the tipping machine, then the tipping machine drives the tundish to turn over, the slag blocks in the tundish are poured into the tipping pit to be accumulated, and finally the slag blocks in the tipping pit are removed by a forklift or manually. A large amount of dust is easily generated when the slag blocks are dumped in the process, the production environment is influenced, and even the surrounding environment is polluted.

The notice number is: CN202097398U, the chinese utility model discloses a tundish tilting device with dust removing function. The device comprises a body of the tundish tipping device, wherein three walls (i.e. tipping pits) are built on the periphery of the body of the tundish tipping device, one side of the body is provided with two oppositely-opened gates to enclose the tundish tipping mechanism on four sides, and the top of each wall is provided with two tracks for moving a movable roof; the inner side of the wall body is provided with a plurality of water spray nozzles for preventing dust from rising. The scheme has the following defects: (1) a large amount of space needs to be reserved on the right side of the roll-over pit so that the movable roof can be conveniently moved to be normally opened, and the occupied space is large. More serious problem is that because steel materials with different lengths are produced in batches in actual production, a workshop is usually provided with a plurality of intermediate tanks with different lengths and a plurality of tipping pits with different lengths. For convenience of management and space saving, the tipping pits with different lengths are designed to be compact and side by side. The notice number is: the scheme of CN202097398U, chinese utility model patent, is designed for only one independent tipping pit, and cannot be applied to actual production, and the specific principle is as follows: assume that the publication number is: when the scheme of chinese utility model patent of CN202097398U is applied to two big and little tipping pits that set up side by side and length differs, the length of removal activity roof need not be less than big tipping pit in order to can shield big tipping pit completely. Therefore, when a small tipping pit with a smaller length is shielded, one end of the movable roof is inevitably beyond the small tipping pit and extends to the upper part of the large tipping pit, so that the intermediate tank cannot be lifted into or taken out of the large tipping pit by a crane, and the normal operation of the large tipping pit is influenced. (2) A large amount of space needs to be reserved in front of the roll-over pit so that two oppositely-opened gates can be normally opened, and the occupied space is large. In addition, when the tipping device dumps the slag, the slag can directly impact the gate and the wall body and even damage the gate and the wall body.
