[0032] Please refer to Figures 1 to 4 As shown, the utility model proposes a kiln oiling device 100, which includes a kiln, a bracket 2, a sealing assembly 3 and an oil gun 41 mechanism 4, wherein the kiln is provided with an oil gun hole 1; the bracket 2 is provided with an installation space 21 and a connecting hole 22 connected to the installation space 21, and the connecting hole 22 is used to communicate with the oil gun hole 1 correspondingly; the sealing assembly 3 is movably connected to the bracket 2 to block or open the oil gun hole 1; the oil gun 41 mechanism 4 includes an oil gun 41 and a transmission assembly 43, the oil gun 41 is movably arranged in the installation space 21 and arranged corresponding to the connecting hole 22, one end of the transmission assembly 43 is connected to the oil gun 41, and the other end of the transmission assembly 43 is connected to the sealing assembly 3; wherein, when the oil gun 41 moves in the installation space 21 to approach or move away from the connecting hole 22, the sealing assembly 3 is driven by the transmission assembly 43 to open or block the oil gun hole 1.

[0033] In this embodiment, the kiln oiling device 100 is composed of a kiln, a bracket 2, a sealing component 3 and an oil gun 41 mechanism 4. The sealing component 3 is movably arranged on a side of the bracket 2 facing the oil gun hole 1 to block or open the oil gun hole 1. The oil gun 41 is movably arranged in the installation space 21 enclosed by the bracket 2 and connected to the sealing component 3 through the transmission component 43. When the oil gun 41 moves toward the connecting hole 22, the oil gun 41 drives the sealing component 3 to gradually move away from the connecting hole 22 and the oil gun hole 1 through the transmission component 43 to open the oil gun hole 1 until the sealing component 3 completely opens the oil gun hole 1 and the oil gun 41 is opened. 1 extends into the kiln through the oil gun hole 1 to replenish the kiln with oil. When the oil gun 41 finishes refueling, the oil gun 41 moves toward the installation space 21 and is pulled out from the oil gun hole 1. At this time, the oil gun 41 drives the sealing component 3 to move toward the connecting hole 22 and the oil gun hole 1 through the transmission component 43 until the oil gun 41 is reset and the sealing component 3 blocks the oil gun hole 1 again. In this way, the oil gun 41 drives the sealing component 3 to move. When the oil gun 41 moves toward the oil gun hole 1, it drives the sealing component 3 to synchronously open the oil gun hole 1. When the oil gun 41 is pulled out from the oil gun hole 1, it drives the sealing component 3 to synchronously block the oil gun hole 1. There is no need to manually move the sealing component 3 alone to open or block the oil gun hole 1, so that the movement of the sealing component 3 can be accurately controlled, and the convenience of the kiln oil replenishment operation is improved.

[0034] In actual implementation, the oil gun hole 1 of the kiln is a bottom-inserted oil gun hole 1, which is approximately parallel to the ground. The movement of the oil gun 41 can be driven manually or by a driving member 42, which is not specifically limited here. When the sealing component 3 blocks the oil gun hole 1, the side of the sealing component 3 facing the oil gun hole 1 abuts against the kiln wall near the oil gun hole 1 to ensure the sealing effect of the sealing component 3.

[0035] In the embodiment of the present utility model, Figures 1 to 3 As shown, two sets of slide rails 23 are provided on one side of the bracket 2 facing the oil gun hole 1 , the two sets of slide rails 23 are arranged opposite to each other, the sealing assembly 3 is slidably connected to the two sets of slide rails 23 , and the connecting hole 22 is located between the two sets of slide rails 23 .

[0036] In this embodiment, the sealing assembly 3 is movably arranged on the bracket 2 through two sets of slide rails 23, and the two sets of slide rails 23 are arranged on both sides of the connecting hole 22, so that the sealing assembly 3 is arranged across the connecting hole 22, and at the same time, the stability of the sealing assembly 3 moving on the bracket 2 is improved. It can be understood that the slide rail 23 is arranged on the side of the bracket 2 facing the oil gun hole 1, so that the sealing assembly 3 is arranged close to the oil gun hole 1, and the bracket 2 may include a crossbeam and two longitudinal beams, that is, the bracket 2 is arranged in a gantry shape, and the crossbeam and the longitudinal beams enclose to form an installation space 21, and the installation space 21 is located on the side of the crossbeam facing the ground, and the slide rail 23 is arranged on the side of the crossbeam facing away from the ground, and the crossbeam is provided with a connecting hole 22, which is not specifically limited here.

[0037] In the embodiment of the present utility model, Figure 1 and Figure 4 As shown, the sealing assembly 3 is provided with a connecting block 311 corresponding to the slide rail 23, and a limiting groove is provided on the side of the connecting block 311 facing the slide rail 23, and a ball 312 is provided in the limiting groove. The slide rail 23 has a slide groove, and at least part of the ball 312 extends into the slide groove.

[0038] In the present embodiment, a connecting block 311 is provided on the side of the sealing component 3 facing the slide rail 23. The connecting block 311 is detachably connected to the main body of the sealing component 3. The connecting block 311 is provided with a limiting groove. The ball 312 is rotatably limited in the limiting groove. At least part of the ball 312 extends out of the limiting groove and at least part of it extends into the slide groove of the slide rail 23. In this way, the sealing component 3 can slide along the slide rail 23. It can be understood that there is a gap between the connecting block 311 and the slide rail 23 to avoid excessive movement resistance of the sealing component 3 due to the friction between the connecting block 311 and the slide rail 23 when the sealing component 3 moves along the slide rail 23, thereby affecting the normal movement and service life of the sealing component 3.

[0039] In the embodiment of the present utility model, Figure 1 and Figure 4 As shown, the sealing assembly 3 includes a mounting plate 31 and a refractory brick 32 . The mounting plate 31 is slidably connected to the slide rail 23 , and the refractory brick 32 is connected to a side of the mounting plate 31 facing away from the slide rail 23 .

[0040] In this embodiment, the sealing assembly 3 is composed of a mounting plate 31 and a refractory brick 32. The mounting plate 31 serves as a bearing plate, bearing the refractory brick 32 to move along the slide rail 23. Optionally, the mounting plate 31 is a high-temperature resistant carbon steel plate, so that the mounting plate 31 has good heat resistance and rigidity, ensuring that the mounting plate 31 is not easily deformed during movement, resulting in the refractory brick 32 being unable to completely block the oil gun 41 or unable to move normally on the slide rail 23, affecting the service life of the mounting plate 31; the thickness of the mounting plate 31 can be 10 mm, so as to further improve the bearing capacity of the mounting plate 31, so as to improve the stability of the mounting plate 31 when driving the refractory brick 32 to move along the slide rail 23; the refractory brick 32 is a sillimanite refractory brick 32, and sillimanite has the characteristics of low thermal expansion coefficient, good corrosion resistance and high refractoriness, so that the refractory brick 32 can be well adapted to the high-temperature use environment of the kiln; the thickness of the refractory brick 32 is 5 mm, and the thickness of the refractory brick 32 can be selected according to actual needs, and is not specifically limited here.

[0041] In the embodiment of the present utility model, Figure 1 and Figure 2As shown, the transmission assembly 43 includes a first pulley 431, a second pulley 432, a connecting rope 433, a counterweight rope 434 and a counterweight block 435. The first pulley 431 and the second pulley 432 are respectively arranged at both ends of the slide rail 23 and are rotatably connected to the bracket 2. The counterweight rope 434 is connected to one end of the sealing assembly 3, and the counterweight rope 434 is wound around the first pulley 431. A counterweight block 435 is provided at the end of the counterweight rope 434. The other end of the sealing assembly 3 is connected to the oil gun 41 through the connecting rope 433, and the connecting rope 433 is wound around the second pulley 432.

[0042] In this embodiment, when the sealing assembly 3 is arranged on the slide rail 23, one end of the sealing assembly 3 is connected to the counterweight block 435 through a counterweight rope 434, wherein the counterweight rope 434 is wound around a first pulley 431 arranged at the end of the slide rail 23, and the counterweight rope 434 is suspended. The extension direction of the counterweight rope 434 from the sealing assembly 3 to the first pulley 431 is parallel to the slide rail 23, and the extension direction of the counterweight rope 434 from the first pulley 431 to the counterweight block 435 is consistent with the direction of gravity. The other end of the sealing assembly 3 is connected to the oil gun 41 through a connecting rope 433, and the connecting rope 433 is wound around a second pulley 432 arranged at the other end of the slide rail 23. The extension direction of the connecting rope 433 from the sealing assembly 3 to the second pulley 432 is parallel to the slide rail 23.

[0043] Under the action of gravity of the counterweight 435, when the oil gun 41 is in a stationary state, the counterweight rope 434 and the connecting rope 433 are in a taut state. When the oil gun 41 moves toward the connecting hole 22, the connecting rope 433 from the second pulley 432 to the oil gun 41 is shortened, and the connecting rope 433 is in a relaxed state. Under the action of gravity, the counterweight 435 pulls the sealing assembly 3 toward the first pulley 431 through the counterweight rope 434, so that the sealing assembly 3 opens the oil gun hole 1 until the oil gun 41 extends into the oil gun hole 1. At this time, the oil gun 41 stops moving, the counterweight rope 434 and the connecting rope 433 are in a taut state and no longer move, and the sealing assembly 3 also stops moving. When the oil gun 41 is pulled out of the oil gun hole 1 and moves to the original position, the oil gun 41 pulls the sealing assembly 3 toward the second pulley 432 through the connecting rope 433 until the oil gun 41 is reset and stops moving. At this time, the sealing assembly 3 blocks the oil gun hole 1. Due to the arrangement of the first pulley 431 and the second pulley 432 , the transmission assembly 43 is pulled parallel to the slide rail 23 by the tension of the counterweight rope 434 and the connecting rope 433 , so as to ensure the stability of the sealing assembly 3 when moving along the slide rail 23 .

[0044] It can be understood that the bracket 2 can be provided with two sets of slide rails 23, and the first pulley 431, the second pulley 432, the connecting rope 433 and the counterweight rope 434 can be provided with two sets, and each set of the first pulley 431, the second pulley 432, the connecting rope 433 and the counterweight rope 434 is respectively provided corresponding to one set of slide rails 23, and the ends of the two sets of connecting ropes 433 are connected to the oil gun 41, and the ends of the two sets of counterweight ropes 434 are connected to the counterweight block 435, so as to prevent the vertical projection of the connecting rope 433 or the counterweight rope 434 from overlapping with the connecting hole 22 or the oil gun hole 1 when the sealing assembly 3 moves along the slide rail 23, thereby affecting the oil gun 41 from extending into the oil gun hole 1 or being pulled out of the oil gun hole 1. At this time, the moving tracks of the oil gun 41 and the counterweight rope 434 are both in the central position between the two sets of slide rails 23 to ensure the force balance of the sealing assembly 3.

[0045] Optionally, a connecting shell can be set on the outer periphery of the oil gun 41, and a buckle is provided on the connecting shell for connection of the connecting rope 433. The connecting shell can be detachably mounted on the oil gun 41, and a buffer can be set between the oil gun 41 and the connecting shell to prevent the tension of the connecting rope 433 from damaging the oil gun 41.

[0046] In the embodiment of the present invention, the connecting rope 433 and / or the counterweight rope 434 are steel ropes to ensure the connection strength between the connecting rope 433 and the counterweight rope 434 to avoid accidents.

[0047] In the embodiment of the present utility model, Figure 1 and Figure 3 As shown, the transmission assembly 43 includes a push rod 436, a limiting rail 437, a push rod 438, a first connecting rod 439a and a second connecting rod 439b. The limiting rail 437 is arranged on the bracket 2. The extending direction of the limiting rail 437 is arranged parallel to the connecting line of the connecting hole 22 and the oil gun hole 1. One end of the first connecting rod 439a is slidably connected to the limiting rail 437, and the other end of the first connecting rod 439a is hinged to one end of the second connecting rod 439b and is connected to the sealing assembly 3 through the push rod 438. The other end of the second connecting rod 439b is slidably connected to the limiting rail 437 and is connected to the oil gun 41 through the push rod 436.

[0048] In this embodiment, the transmission assembly 43 is composed of a push rod 436, a limiting rail 437, a push rod 438, a first connecting rod 439a and a second connecting rod 439b. The setting direction of the limiting rail 437 is parallel to the moving direction of the oil gun 41. The hinged ends of the first connecting rod 439a and the second connecting rod 439b are connected to the sealing assembly 3 through the push rod 438. The push rod 438 is arranged in parallel with the slide rail 23. The end of the first connecting rod 439a away from the second connecting rod 439b and the end of the second connecting rod 439b away from the first connecting rod 439a are both slidably arranged on the limiting rail 437. The second connecting rod 439b is away from the first connecting rod 439a. One end of the first connecting rod 439a is also connected to the oil gun 41 through the push rod 436. When the oil gun 41 moves toward the oil gun hole 1, the oil gun 41 drives the push rod 436 to move the sliding end of the second connecting rod 439b toward the direction close to the first connecting rod 439a. At this time, the sliding end of the first connecting rod 439a moves toward the direction close to the second connecting rod 439b, and the hinged ends of the first connecting rod 439a and the second connecting rod 439b move away from the oil gun hole 1, and then drive the sealing assembly 3 along the slide rail 23 away from the oil gun hole 1 through the push rod 438, so that the oil gun hole 1 is opened and the oil gun 41 extends into the oil gun hole 1. When the oil gun 41 is pulled out from the oil gun hole 1 and moves to the original position, the oil gun 41 drives the sliding end of the second connecting rod 439b to move away from the first connecting rod 439a through the push rod 436. At this time, the sliding end of the first connecting rod 439a moves away from the second connecting rod 439b, and the hinged ends of the first connecting rod 439a and the second connecting rod 439b move toward the oil gun hole 1, and then the seal assembly 3 is driven by the push rod 438 to approach the oil gun hole 1 along the slide rail 23, so that the seal assembly 3 blocks the oil gun hole 1, and the oil gun 41 returns to the original position. In this way, the seal assembly 3 opens or blocks the oil gun hole 1 as the oil gun 41 moves, which improves the convenience of kiln oil replenishment.

[0049] In actual implementation, the oil gun 41 is lifted and lowered in the vertical direction, the slide rail 23 is extended in the horizontal direction, and the limit rail 437 is extended in the vertical direction, which is not specifically limited here.

[0051] In this embodiment, the push rod 436 is arranged in an L shape to avoid the push rod 438 or the sealing assembly 3, so as to prevent the push rod 436 from colliding with the push rod 438 or the sealing assembly 3 when the oil gun 41 is extended into the oil gun hole 1, thereby affecting the movement of the oil gun 41 and the normal transmission of the transmission assembly 43. When the oil gun 41 is in the original position or extended into the oil gun hole 1, the first connecting rod 439a and the second connecting rod 439b are connected at an angle, so that the hinged ends of the first connecting rod 439a and the second connecting rod 439b always move on one side of the limiting slide rail 23, and correspondingly, the sealing assembly 3 also moves on one side of the oil gun hole 1, so as to ensure that when the oil gun 41 is in the original position, the sealing assembly 3 blocks the oil gun hole 1, and when the oil gun 41 moves toward the oil gun hole 1, the sealing assembly 3 opens the oil gun hole 1.
