Problems solved by technology
[0003] Generally, the depth of the pull rod entering the furnace eye is 3-4 meters, and the distance of 3-4 meters at the front end is called the working section. Since the working section is inserted into the furnace eye, it will be subjected to high temperature, so after being pulled out, the front end 3-4 meters will become soft. , When the pull rod is finished dredging the furnace hole, it withdraws from the furnace hole. The soft working section has no support, and the pull rod will slowly bend and deform under the action of gravity. If the bending is too large, the pull rod must be replaced or straightened, which affects the Normal use with increased workload

The invention provides an ore smelting hole-pulling dredging device which comprises a rail, a pull rod, a pull rod clamping mechanism, a pull rod guide mechanism and a pull rod drive mechanism. At least one pull rod supporting trolley capable of sliding front and back is arranged on the portion, located between the pull rod guide mechanism and the pull rod clamping mechanism, on the rail. The pull rod penetrates through the pull rod supporting trolleys to be supported by the pull rod supporting trolleys. Flexible ropes are connected between the pull rod mechanism and the pull rod supporting trolleys and between the pull rod supporting trolleys and the pull rod clamping mechanism. By means of the ore smelting hole-pulling dredging device, the pull rod for dredging smelting holes can be prevented from being bent and deformed downwards excessively, the service life of the ore smelting hole-pulling dredging device is prolonged, and inconvenience caused by pull rod replacement or straightening is avoided or reduced.
Description
technical field [0001] The invention relates to a furnace hole pulling device for a submerged arc furnace, in particular to a dredging device for a submerged arc hole. Background technique [0002] The eye pulling machine for submerged arc furnace is mainly composed of track, pull rod, pull rod clamping mechanism, pull rod guiding mechanism and pull rod driving mechanism. One end of the track is equipped with a first sprocket, the other end is equipped with a second sprocket matching the first sprocket, a chain is set between the first sprocket and the second sprocket, and the second sprocket and the second sprocket are connected to each other. The pull rod driving mechanism is connected; the pull rod guide mechanism is fixedly installed on the front part of the track, and the pull rod guide mechanism is provided with a guide hole, and the pull rod passes through the guide hole and is fixed with the pull rod clamping mechanism; the pull rod clamping mechanism Set on the tra...
