Description

Technical Field

[0001] This utility model relates to the field of auxiliary equipment technology for iron and steel smelting, and in particular to an integrated feeding and pressing device for medium frequency furnaces. Background Technology

[0002] The working frequency of the medium frequency induction furnace (hereinafter referred to as medium frequency furnace) is between 50 and 2000 Hz. Its heating principle is electromagnetic induction, and it has the characteristics of fast heating speed, high production efficiency and less oxidation and decarburization.

[0003] As the main equipment for metal smelting in enterprises such as casting, special steel, and non-ferrous metal smelting, the smelting efficiency of the intermediate frequency furnace determines the overall production efficiency of the enterprise. Given a fixed furnace life, the charging speed is the key factor determining the smelting efficiency of the intermediate frequency furnace. Therefore, improving the effective charging speed of the intermediate frequency furnace is extremely important for improving the production efficiency of the enterprise.

[0004] When feeding materials into an intermediate frequency furnace, irregular sizes and shapes of materials can easily cause jamming. Currently, the method used is to manually use tools such as shovels and steel pipes to push the material stuck at the furnace opening into the intermediate frequency furnace. However, this method has the disadvantages of being highly dangerous, producing high temperatures and large amounts of smoke at the furnace opening, resulting in a very harsh working environment and low work efficiency.

[0005] Therefore, there is a need for an integrated feeding and pressing device for medium-frequency furnaces, which can promptly press the material when a jam occurs during feeding, thereby increasing the feeding speed of medium-frequency furnaces. Summary of the Invention

[0006] This invention provides an integrated feeding and pressing device for a medium-frequency furnace, which can press the material in a timely manner and improve the feeding speed.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] An integrated feeding and pressing device for a medium-frequency furnace includes a vehicle body and a counterweight mechanism; the vehicle body includes an upper vehicle body and a lower vehicle body; the lower vehicle body includes a lower frame, on which a slewing mechanism is provided; wheels are provided at the bottom of the lower frame;

[0009] The upper body includes an upper frame and a hopper. The hopper is hinged to the upper frame. A first driving device is provided on both sides of the upper frame. One end of the first driving device is hinged to the upper frame and the other end is hinged to the hopper.

[0010] The hammer mechanism includes a hammer frame, a hammer head, and a second drive device. The hammer frame includes a crossbeam with side beams at both ends. The side beams are composed of a large arm, a small arm, and a transition arm. The hammer head is located in the middle of the crossbeam. One end of the large arm is fixedly connected to the crossbeam, and the other end is hinged to the upper frame. The end of the small arm is hinged to one end of the second drive device, and the other end of the second drive device is hinged to the upper frame.

[0011] The slewing mechanism includes an internal gear slewing bearing and a slewing motor; the lower frame is bolted to the inner ring of the internal gear slewing bearing, and the upper frame is bolted to the outer ring of the internal gear slewing bearing; the housing of the slewing motor is fixedly connected to the upper frame, and the internal gear slewing bearing and the slewing motor are driven by gear meshing.

[0012] The upper arm and lower arm of the side beam form an included angle α, which ranges from 45° to 65°.

[0013] The upper frame is equipped with a counterweight.

[0014] The first and second driving devices are hydraulic cylinders.

[0015] The wheel includes a driven wheel and a driving wheel; the driven wheel is located at the front end of the bottom of the lower frame; the driving wheel is located at the rear end of the bottom of the lower frame and is driven by a hydraulic motor.

[0016] The bottom of the lower frame is provided with a synchronous shaft, and the driven wheel is connected to both ends of the synchronous shaft through a coupling.

[0017] Both the driven wheel and the driving wheel have a double-sided double-rim structure.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] 1) This utility model has both feeding and pressing functions. When feeding, if irregular material gets stuck, the second driving device can drive the heavy hammer head to work and press the stuck material into the furnace, thereby improving the efficiency of clearing the stuck material and thus increasing the feeding speed.

[0020] 2) The new type of hammer frame is equipped with a second driving device on each side for pressing the material, which makes the cleaning and pressing force large and the hammer frame is evenly stressed, resulting in a stable overall structure and a long service life.
