[0002] The induction furnace melts the scrap steel inductionly in the furnace body. After the furnace is full of molten steel, the steel tapping operation is carried out. The steel tapping method adopts the hydraulic tilting furnace shell method. Specifically, the hydraulic cylinder lifts the furnace body, and the furnace body rotates around the rotating bracket. The molten steel flows out along the steel tapping trough into the ladle.

[0003] During the process of tilting the furnace and tapping steel, the entire furnace working platform rises along with the furnace body, revealing a large gap on the charging platform (that is, during normal melting work, the furnace working platform is laid flat to cover the gap). This is very dangerous. If you are not careful, it may easily cause the workpiece to fall or even the operator to fall into the air.

[0004] This gap is a necessary space for the furnace tilting operation, and it is impossible to fix the cover. Generally, a fixed railing enclosure is made along the edge of the platform to prevent danger, but the fixed railing enclosure causes a lot of operational inconveniences. For example, during the normal melting process of the furnace, workers entering or materials being transported often collide with the fixed railing enclosure, causing a lot of inconvenience; Utility Model Content

A supporting cylinder is connected to the lower end of the rear baffle, and the other end of the supporting cylinder is connected to the base.

[0008] Preferably, the side baffle comprises a plurality of side connecting rods and a side connecting net, the plurality of side connecting rods form a fan shape, and the side connecting net is fixed in the fan shape formed by the plurality of side connecting rods.

[0009] Preferably, the rear baffle comprises a plurality of rear connecting rods and a rear connecting net, the plurality of rear connecting rods form a rectangle, and the rear connecting net is fixed in the rectangle formed by the plurality of rear connecting rods.

[0010] Preferably, a rotation support shaft is fixedly connected to the side connecting rod.

[0011] Preferably, the lower end of the rear connecting rod is connected to a support seat, and the support seat is connected to the telescopic end of the support cylinder.

[0012] Preferably, the side connecting rods and the rear connecting rods are square tubes.

[0013] Compared with the prior art, the utility model provides an automatic lifting fence protection device for an induction furnace, which has the following beneficial effects:

[0014] The parts not involved in the device are the same as the existing technology or can be implemented by the existing technology. The utility model can ensure the safety of the operator by setting up a U-shaped guardrail, and the set cylinder can automatically support and be compressed. No additional operating device is required, the operation of the furnace body is not affected, and no additional installation space is occupied. BRIEF DESCRIPTION OF THE DRAWINGS
