Description

Technical Field

[0001] The utility model belongs to the technical process and safety technical field of ore-fired furnaces, and in particular relates to an anti-dropping device for an additional hopper of a furnace tamping machine. Background Art

[0002] Domestic ore-blast furnaces are divided into fully enclosed ore-blast furnaces and semi-enclosed ore-blast furnaces. Fully enclosed ore-blast furnaces use a distributor to regularly distribute the material surface in the furnace, and do not require manual maintenance and adjustment of the material surface; while semi-enclosed ore-blast furnaces require the use of a tamping machine to assist in the maintenance of the material surface in the furnace and additional adjustment of other materials for the furnace condition during the smelting process. In order to stabilize and adjust the furnace condition, some peer companies also use manual maintenance of the material surface and additional adjustment of materials. The safety risks during the operation are extremely great and the labor intensity is high. Most semi-enclosed ore-blast furnaces basically use tamping machines, which are relatively simple to operate, have low safety risks and low labor intensity.

[0003] The additional hopper is an indispensable auxiliary equipment and facility in the semi-closed ore-fired furnace smelting operation process. However, the additional hopper equipment of the current furnace tamping machine has deformation and usage defects after being subjected to long-term high-temperature baking and wear during long-term use. There are several problems: First, it is difficult to reinstall the additional hopper of the furnace tamping machine after it falls off during use, and it cannot be restored due to the weight of the hopper and no suitable auxiliary facilities can be found; second, the reinstallation process of the hopper push plate after it falls off requires manual installation, and the working space is small and the safety risk is high. Utility Model Content

[0004] The utility model aims to provide an additional hopper anti-dropping device for a tamping machine to solve the above problem.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0006] A furnace tamping machine additional hopper anti-slip device comprises a furnace tamping machine support arm and a hopper, a push plate is arranged in the hopper, a U-shaped clip is arranged on the top surface of the furnace tamping machine support arm, an anti-slip pin is passed through the U-shaped clip, lifting ears I are symmetrically arranged on the end wall of the hopper close to the furnace tamping machine support arm, lifting ears II are arranged between the lifting ears I, lifting ears III are arranged on the push plate, a chain I is arranged between the two lifting ears I, the chain I is passed through the U-shaped clip, and a chain II is arranged between the lifting ears II and the lifting ears III to connect.

[0007] In order to further realize the utility model, the open end of the U-shaped clip is arranged in a direction away from the hopper, and the axes of the U-shaped clip, the lifting ear nose II and the lifting ear nose III are in the same plane with the axis of the tamping machine support arm.

[0008] In order to further realize the utility model, the lifting ear nose II is arranged at the midpoint of the two lifting ear noses I.

[0009] In order to further realize the utility model, the bottom end of the anti-dropping pin is fixedly connected to the supporting arm rod of the tamping machine.

[0010] Compared with the prior art, the utility model has the following beneficial effects:

[0011] The utility model adds a U-shaped self-locking clip on the support arm of the tamping machine, uses a chain to connect it with the lifting ear nose I, and during use, the chain is clamped into the U-shaped clip, and an anti-dropping pin is installed to realize the anti-dropping function of the hopper; and respectively installs a lifting ear nose II and a lifting ear nose III at the center position of the hopper body and the pusher plate, and uses a chain with a U-shaped clip for fixed connection, thereby preventing the pusher plate from falling off during the process of adding material (pushing material); the utility model improves the production operation rate, reduces the operation difficulty and safety risks, and stably ensures the safe, stable and smooth operation of the ore-heating furnace and the start-up productivity of the ore-heating furnace.
