Description

Technical field:

[0001] The utility model relates to the technical field of calcium carbide production, in particular to a clamping device for hoisting a burn-through device busbar. Background technology:

[0002] The burner is the main equipment used for the eye opening operation of the calcium carbide furnace. The burner is powered by the burner busbar. Usually, the burner busbar is exposed on the ground, which is very dangerous. Therefore, the burner busbar is fixed between two clamps by bolts. A certain gap is left between the burner busbars to avoid contact and short circuit, and the two clamps are hung on the beams by hooks. The current problem is that when the burner busbar moves with the burner, it is easy to cause the bolts to loosen, which will cause the burner busbars between the two clamps to contact for a long time, forming a circuit, and thus causing sparks.

[0003] Therefore, it is necessary to propose a new technical solution to solve the problems existing in the current actual production process. Utility model content:

[0004] The utility model aims to provide a clamping device for hoisting a burn-through device busbar, so as to solve the problems raised in the above background technology.

[0005] The utility model is implemented by the following technical solutions:

[0006] A clamping device for hoisting a burn-through device busbar comprises a lower pressing plate, a lower insulating plate, an upper insulating plate and an upper pressing plate arranged in sequence from bottom to top, wherein the lower pressing plate, the lower insulating plate, the upper insulating plate and the upper pressing plate are fixed together by bolts, three threading holes are evenly opened between the lower insulating plate and the upper insulating plate, and a lifting lug is fixed to the middle of the upper surface of the upper pressing plate.

[0007] Preferably, the lower pressing plate, the lower insulating plate, the upper insulating plate and the upper pressing plate are symmetrically provided with a plurality of through holes on both sides close to the threading hole.

[0008] Preferably, the bolt is inserted into the through hole and its end is fixedly connected by a nut.

[0009] The utility model has the advantages that the burn-through device busbar is passed through the threading hole, and the lower insulating plate and the upper insulating plate are used to insulate and isolate the adjacent burn-through device busbars. Even if the bolts are loose, it can ensure that there is no contact between the two adjacent burn-through device busbars, thereby avoiding short circuits and preventing sparks.
