DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] like Figure 1 As shown, a detection rod automatic slag knocking device includes a knocking hammer 1, a cantilever 2, a rotating drive member 3 and a supporting connecting member 4. The knocking hammer 1 is rotatably connected to one end of the cantilever 2, and the other end of the cantilever 2 is connected to the rotating end of the rotating drive member 3. The rotating drive member 3 is used to drive the cantilever 2 to rotate, and the rotating drive member 3 is connected to the supporting connecting member 4.

[0025] Its working principle is that the cantilever 2 is driven to rotate by the rotating driving member 3, thereby driving the percussion hammer 1 to rotate and percuss the detection rod 01. The supporting connecting member 4 can be matched and designed to support the percussion hammer 1, the cantilever 2 and the rotating driving member 3 according to the installation requirements, and connected to the installation position. In this way, the detection rod can be continuously cleaned of the gap, and the metal slag is kept from adhering to the surface to affect the detection.

[0026] According to the above working principle, some preferred embodiments or implementation structures are provided, such as Figure 1The hammer 1 is in the shape of a long strip. In this way, when the detection rod 01 rises vertically, it can knock against it for many times to keep in contact with it. If it is short, it is not easy to contact with the detection rod 01, so it is not easy to knock for many times.

[0027] like Figure 2 As shown, the cantilever 2 includes an upper arm beam 21 and a lower arm beam 21 and a stopper 22. A space 201 for the percussion hammer 1 to pass through is provided at one end of the upper arm beam 21. One end of the percussion hammer 1 is rotatably connected in the space 201. The stopper 22 is installed at one end of the upper arm beam 21 to limit the rotation angle of the percussion hammer 1. The other end of the upper arm beam 21 is connected to the rotating end of the rotating driving member 3. In this way, the mass of the cantilever 2 can be reduced. Those skilled in the art should be able to imagine that the structure of the cantilever 2 can also be in the form of a plate plus a bearing connected to the percussion hammer.

[0028] There is an arc-shaped protrusion 211 in the space 201 at one end of the upper and lower arm beams 21, and the arc-shaped protrusion 211 is used to be tangent to the upper and lower surfaces of the percussion hammer 1. This can reduce friction and limit the rotation of the percussion hammer 1.

[0029] See also Figure 1 and Figure 2 As shown, one end of the percussion hammer 1 is connected to the upper and lower arm beams 21 through a pin 23 and a cotter pin 24, or an arc groove is provided on the upper and lower surfaces of the percussion hammer 1, and the arc groove and the arc protrusion 211 cooperate with each other to connect to the upper and lower arm beams 21. This is simple to install, and the pin 23 can be installed and disassembled, and the percussion hammer 1 can be installed by only pulling out or buckling the cotter pin. Those skilled in the art should be able to think that other structures of snap-fit ​​parts or pins can also realize the rotational installation of the percussion hammer 1, such as a pin with a thread and a pin with a rivet head.

[0030] The rotating drive member 3 includes a motor 31, a belt assembly 32 and a rotating shaft 33. The motor 31 and the belt assembly 32 are both mounted on the supporting connector 4. The belt assembly 32 is driven by the motor 31, and the rotating shaft 33 is driven to rotate by the belt assembly 32. The rotating shaft 33 is used as the rotating end of the rotating drive member 3 to connect the other end of the cantilever 2. Those skilled in the art should know that the rotating shaft 33, the upper and lower arm beams 21, and the gear lever 22 are connected by welding, and the rotating shaft and the pulley on the belt assembly 32 can be connected by a keyway. In this way, the motor can be installed at the far end, and the rotating drive member 3 has a simple structure and is easy to manufacture. Those skilled in the art should be able to imagine that the rotating drive member 3 can also be other structures for driving the percussion hammer 1 to rotate.

[0031] A protective housing 34 is disposed outside the exposed rotating ends of the motor 31 and the belt assembly 32 .

[0032] The rotating shaft 33 is rotatably connected to the supporting connecting member 4 through a bearing. This can reduce the rotation resistance at the rotating shaft 33.

[0033] The automatic slag knocking device may further include a protective enclosure 35, which is sleeved outside the rotation area of ​​the knocking hammer 1 and connected to the supporting connector 4. This can improve operational safety.

[0034] The automatic slag knocking device may further include a lifting assembly 5, which is arranged on one side of the knocking hammer 1 and is used to lift the detection rod 01 to within the knocking range of the front end of the knocking hammer 1. The lifting assembly may be an electric hoist installed on the furnace top platform, or a self-designed hoist, which will not be described in detail.

[0035] When in use, the detection rod 01 is inserted into the furnace from the detection port 03 on the top platform 02 of the smelting furnace, stays for 10 seconds, and then is lifted out of the furnace from the detection port 03 through the lifting assembly. The detection rod 01 is attached with a thick layer of metal slag 04 on the surface of the detection rod formed after the metal objects in the furnace are cooled. The second pulley in the belt assembly 32 is driven to rotate by the speed regulating motor 31, and then the first pulley is driven to rotate by the V-belt in the belt assembly, thereby driving the rotating shaft 33 to rotate; after the rotating shaft 33 is connected to the two seat bearings, it is fixed on the bracket as a whole, and the protective enclosure 35 is welded on the bracket to prevent the rotating shaft 33 from injuring people when it rotates; the protective shell 3 4 is fixed on the bracket, and the V-belt in the belt assembly and the motor end are protected for safety. The percussion hammer 1 is connected and prevented from falling off with the upper and lower arm beams 21 through the pin shaft 23 and the cotter pin 24; the rotation of the first pulley drives the rotation of the rotating shaft 33, and the upper and lower arm beams 21 in the rotating shaft 33 drive the percussion hammer 1 to hit the metal slag 04 on the surface of the probe rod 4 on the probe rod 01. The metal slag will fall off the probe rod 01 after being struck, and the percussion hammer 1 will bend at the pin shaft 23 by itself after being acted upon by the reaction force of the probe rod 01 during the percussion, so as to ensure that the percussion hammer 1 passes through the obstacle smoothly. At the same time, after leaving the obstacle, it will open by itself under the action of centrifugal force to perform the next percussion. The speed and direction of the percussion can be achieved by controlling the speed regulating motor 31 through the PLC.
