Description

Technical Field

[0001] The present application relates to the field of ceramic kilns, and in particular to a kiln car. Background Art

[0002] At present, the firing kilns for sanitary ceramics in the industry generally use an integral frame composed of silicon carbide columns, beams, flat beams, and thin plates to support multiple products to be sintered. However, when part of the frame is damaged, it needs to be repaired or scrapped as a whole, which not only takes time to repair, but also requires the firing operation to be suspended, resulting in high kiln car costs and low output efficiency. Summary of the invention

[0003] In order to improve the maintenance method of a kiln car and increase the efficiency of firing products, the present application provides a kiln car.

[0004] The kiln car provided in this application adopts the following technical solution: A kiln car comprises a car body, wherein the car body is provided with four evenly distributed upright posts, the upright posts are plugged with support rods, the support rods are provided with a plurality of plug holes evenly distributed from top to bottom, the plug holes on all the support rods are arranged with corresponding heights, wherein a crossbeam horizontally plugged into the plug holes is arranged between two adjacent support rods, a corresponding crossbeam is arranged between another two support rods, longitudinal beams arranged in pairs are overlapped on two opposite crossbeams, and a support plate for holding products is arranged between the pair of longitudinal beams.

[0005] By adopting the above technical solution, the crossbeam is inserted into the insertion hole between the two support rods to connect with the support rods. Then the two ends of the longitudinal beam are respectively overlapped on the corresponding crossbeams to form a detachable frame. Then the support plate is placed on the adjacent longitudinal beams. When part of the structure is damaged, the components of the damaged part can be directly replaced without overall repair or scrapping, thereby reducing maintenance costs and improving maintenance efficiency.

[0006] Optionally, a pair of longitudinal beams are provided with limiting grooves parallel to the longitudinal beams on one side close to each other, and the support plate is overlapped in the limiting grooves.

[0007] By adopting the above technical solution, both ends of the support plate are respectively placed in the limiting grooves, so that the support plate is connected to the two longitudinal beams, whereby the longitudinal beams and the support plate cooperate to support the product to be fired.

[0008] Optionally, an upper plate mechanism for laying a support plate is provided on the cross beam, and the upper plate mechanism includes a material storage box. Connecting blocks are provided below both sides of the material storage box, and connecting grooves for accommodating longitudinal beams are provided on the connecting blocks. A limiting assembly for lowering the support plate is provided between the two connecting blocks.

[0009] By adopting the above technical solution, the connecting block slides on the longitudinal beam through the connecting groove, so that the material storage box can slide above the two longitudinal beams. When the connecting block moves a certain distance, the limiting assembly lowers a support plate in the material storage box so that the support plate is overlapped between the two longitudinal beams. This process is repeated. When the connecting block passes through the entire longitudinal beam, the space between the two longitudinal beams is fully paved with support plates, thereby enabling the support plates to be laid quickly and conveniently, thereby improving the kiln loading efficiency.

[0010] Optionally, the limiting assembly includes a limiting plate slidably connected to the connecting block, the limiting plates on the two connecting blocks are arranged opposite to each other, and a partition plate is also provided on the side of the limiting plate close to the material storage box, the partition plate is slidably connected to the connecting block, and a driving member for driving the limiting plate and the partition plate to move is provided in the connecting block, and the limiting plate and the partition plate move in opposite directions.

[0011] By adopting the above technical solution, the support plates of the storage box are stacked and supported by the limiting plates. When the limiting plates move toward the inside of the connecting block, the partition plates move toward the support plates and separate the lowest support plates from the other support plates. When the limiting plates completely enter the inside of the connecting block, the support plates between the partition plates and the limiting plates fall between the two longitudinal beams. Then the partition plates move toward the inside of the connecting block. At this time, the limiting plates move to their original positions. When the partition plates completely enter the inside of the connecting block, all the support plates fall onto the limiting plates. Therefore, during the movement of the connecting block along the longitudinal beams, the movement of the limiting plates and the partition plates is controlled, so that the support plates can be laid between the two longitudinal beams in sequence.

[0012] Optionally, a cavity is opened inside the connecting block, the limiting plate and the partition plate are both inserted into the cavity, the driving member includes a driving gear arranged in the cavity and rotatably connected to the connecting block, the driving gear is located between the limiting plate and the partition plate, and a driving rack meshing with the same driving gear is arranged on the side where the limiting plate and the partition plate are close to each other, the limiting plate at one end located in the cavity is hinged with a connecting rod, the connecting rod at one end away from the limiting plate is hinged with a transmission gear, and the hinge point is located at the eccentric point of the transmission gear, and the transmission gear is rotatably connected to the connecting block.

[0013] By adopting the above technical solution, the transmission gear rotates and drives the limit plate to slide back and forth through the connecting rod. The limit plate drives the driving gear to rotate through the driving rack, and the driving gear simultaneously drives another driving rack to move, thereby the partition plate and the limit plate move in opposite directions.

[0014] Optionally, a roller is rotatably connected to the inner wall of the connecting groove, and the roller abuts against the side wall of the longitudinal beam at the same time. The connecting block is provided with a driving motor, and the output shaft of the driving motor is fixedly connected to the roller coaxially, and a gear set connecting the output shaft and the transmission gear is provided between the two.

[0015] By adopting the above technical solution, the connecting block is overlapped on the longitudinal beam through the roller. When the driving motor drives the roller to rotate, the roller drives the connecting block to move along the direction of the longitudinal beam. At the same time, the output shaft of the driving motor drives the transmission gear to rotate, so that the connecting block lays the support plate downward while moving.

[0016] Optionally, the material storage box includes a left shell and a right shell, and a telescopic component is further provided between the left shell and the right shell.

[0017] By adopting the above technical solution, the distance between the two longitudinal beams is determined by the specifications of the product to be fired. Therefore, the telescopic assembly between the left shell and the right shell can adjust the distance between the left shell and the right shell, thereby adjusting the length of the corresponding support plate so that the support plate can meet the distance between the two longitudinal beams.

[0018] Optionally, the telescopic assembly includes an adjustment rack arranged on the left shell, and the end of the adjustment rack away from the left shell is inserted into the right shell. The right shell is rotatably connected to a rotating rod, and an adjustment gear meshing with the adjustment rack is fixed at one end of the rotating rod located in the right shell. A clamping part for clamping the adjustment gear is also provided inside the right shell.

[0019] By adopting the above technical solution, the clamping piece is opened, and then the rotating rod is driven. The rotating rod drives the adjusting rack to slide through the adjusting gear, thereby adjusting the distance between the left shell and the right shell. After the distance is determined, the clamping piece fixes the distance between the left shell and the right shell, thereby improving the stability of the storage box.

[0020] Optionally, the rotating rod is slidably connected to the right shell along its axial direction, the clamping member includes a clamping tooth arranged inside the right shell, the adjusting rack can be engaged with the clamping tooth, and a return spring is also provided between the adjusting gear and the right shell.

[0021] By adopting the above technical solution, the sliding rotating rod disengages the adjusting gear from the engaging teeth, while the adjusting gear remains engaged with the adjusting rack. Thus, rotating the adjusting gear can drive the sliding of the adjusting rack, thereby adjusting the distance between the left shell and the right shell. When the rotating rod is released, the return spring returns the adjusting gear to its original position, so that the adjusting gear engages with the engaging teeth and the adjusting rack at the same time, thereby fixing both the adjusting gear and the adjusting rack.

[0022] In summary, the present application includes at least one of the following beneficial technical effects: When a prefabricated kiln car is installed, when part of the structure is damaged, the components of the damaged part can be directly replaced without the need for overall repair or scrapping, thereby reducing maintenance costs and improving maintenance efficiency; The upper plate mechanism can quickly and conveniently lay the support plate between the two longitudinal beams, improving the kiln loading efficiency; The telescopic assembly between the left shell and the right shell can adjust the distance between the left shell and the right shell, thereby adjusting the length of the corresponding support plate so that the support plate can conform to the distance between the two longitudinal beams, thereby corresponding to the specifications of the product to be fired, thereby improving the applicability of the kiln car.

DETAILED DESCRIPTION

[0028] The present application is further described in detail below in conjunction with the accompanying drawings.

[0029] The embodiment of the present application discloses a kiln car. Example

[0030] Reference Figure 1 A kiln car comprises a car body 1, four corners of the upper side of the car body 1 are fixedly connected with columns 11, support rods 2 are plugged into the columns 11, a plurality of plug holes 21 evenly distributed from top to bottom are provided on the support rods 2, corresponding plug holes 21 are provided at the same horizontal height of other support rods 2, a crossbeam 3 horizontally plugged into the plug hole 21 is provided between two adjacent support rods 2, a corresponding crossbeam 3 is provided between the other two support rods 2, two opposite crossbeams 3 are overlapped with longitudinal beams 4 arranged in pairs, and a support plate 5 for holding products is provided between the pair of longitudinal beams 4.

[0031] The crossbeam 3 is inserted into the insertion hole 21 between the two support rods 2, thereby connecting with the support rods 2, and then the two ends of the longitudinal beam 4 are respectively overlapped on the corresponding crossbeam 3, thereby forming a detachable frame, and then the support plate 5 is placed on the adjacent longitudinal beam 4. When part of the structure is damaged, the components of the damaged part can be directly replaced without the need for overall repair or scrapping.

[0032] Both sides of the longitudinal beam 4 are provided with limiting grooves parallel to the longitudinal beam 4, and the support plate 5 is overlapped in the limiting grooves on two adjacent longitudinal beams 4. Both ends of the support plate 5 are respectively placed in the limiting grooves, so that the support plate 5 connects the two longitudinal beams 4, so that the longitudinal beam 4 and the support plate 5 can cooperate to support the product to be fired.

[0033] The implementation principle of Example 1 is: gradually assume each layer of cross beams 3 and longitudinal beams 4 on the support rods 2 from bottom to top, and lay support plates 5 between two adjacent longitudinal beams 4. After each layer of support plates 5 is laid, the product to be fired is placed on the support plates 5, and then the next layer of support plates 5 is built, thereby completing the construction of the entire kiln car. Example

[0034] Reference Figure 2 and Figure 3 The difference between this embodiment and embodiment 1 is that an upper plate mechanism 6 for laying the support plate 5 is provided on the cross beam 3, and the upper plate mechanism 6 includes a storage box 61 for storing a stack of support plates 5, and the storage box 61 includes a left shell 611 and a right shell 612, and a telescopic component 62 is also provided between the left shell 611 and the right shell 612.

[0035] The distance between the two longitudinal beams 4 is determined by the specifications of the product to be fired, so the telescopic assembly 62 between the left shell 611 and the right shell 612 can adjust the distance between the left shell 611 and the right shell 612, thereby adjusting the length of the corresponding support plate 5. In order to improve the applicability of the storage box 61, the storage box 61 adjusts the distance between the left shell 611 and the right shell 612 through the telescopic assembly 62, so as to store support plates 5 of different lengths, so that the support plates 5 can meet the distance between the two longitudinal beams 4.

[0036] The telescopic assembly 62 includes an adjusting rack 621 slidably connected to the left shell body 611, and one end of the adjusting rack 621 away from the left shell body 611 penetrates into the right shell body 612. A rotating rod 622 is rotatably connected to the right shell body 612, and the rotating rod 622 is slidably connected to the right shell body 612 along its axial direction. An adjusting gear 623 meshing with the adjusting rack 621 is fixed to one end of the rotating rod 622 located in the right shell body 612, and a clamping piece for clamping the adjusting gear 623 is also fixed inside the right shell body 612.

[0037] Open the card connector, then drive the rotating rod 622, the rotating rod 622 drives the adjustment rack 621 to slide through the adjustment gear 623, so as to adjust the distance between the left shell 611 and the right shell 612. After the distance is determined, the card connector fixes the distance between the left shell 611 and the right shell 612.

[0038] A snap-fitting tooth 624 is also provided inside the right housing 612, and the adjusting rack 621 can mesh with the snap-fitting tooth 624, and a return spring 625 is also provided between the adjusting gear 623 and the right housing 612. The sliding rotating rod 622 disengages the adjusting gear 623 from the snap-fitting tooth 624, while the adjusting gear 623 remains meshed with the adjusting rack 621, and thus the adjusting gear 623 can be rotated to drive the sliding of the adjusting rack 621, thereby adjusting the distance between the left housing 611 and the right housing 612, and when the rotating rod 622 is released, the return spring 625 returns the adjusting gear 623 to its original position, so that the adjusting gear 623 meshes with the snap-fitting tooth 624 and the adjusting rack 621 at the same time, and thus both the adjusting gear 623 and the adjusting rack 621 are fixed.

[0039] Reference Figure 3 and Figure 4 A connecting block 63 is fixed below both sides of the storage box 61. A connecting groove for accommodating the longitudinal beam 4 is opened on the connecting block 63. A limiting component 64 for lowering the support plate 5 is provided between the two connecting blocks 63.

[0040] The connecting block 63 slides on the longitudinal beam 4 through the connecting groove, so that the storage box 61 can slide above the two longitudinal beams 4. When the connecting block 63 moves a certain distance, the limiting assembly 64 lowers a support plate 5 in the storage box 61, so that the support plate 5 is overlapped between the two longitudinal beams 4. This is repeated. When the connecting block 63 passes through the entire longitudinal beam 4, the space between the two longitudinal beams 4 is fully paved with support plates 5, so that the support plates 5 can be laid quickly and conveniently, thereby improving the kiln loading efficiency.

[0041] The limiting assembly 64 includes a limiting plate 641 slidably connected to the connecting block 63. The limiting plates 641 on the two connecting blocks 63 are arranged opposite to each other. A partition plate 642 is also provided on the side of the limiting plate 641 close to the material storage box 61. The partition plate 642 is slidably connected to the connecting block 63. A driving member for driving the limiting plate 641 and the partition plate 642 to move is provided in the connecting block 63, and the moving directions of the limiting plate 641 and the partition plate 642 are opposite.

[0042] The support plates 5 of the storage box 61 are stacked and supported by the limiting plates 641. When the limiting plates 641 move toward the inside of the connecting block 63, the partition plates 642 move toward the support plates 5 and separate the lowest support plates 5 from the other support plates 5. When the limiting plates 641 completely enter the inside of the connecting block 63, the support plates 5 located between the partition plates 642 and the limiting plates 641 fall between the two longitudinal beams 4. Then the partition plates 642 move toward the inside of the connecting block 63. At this time, the limiting plates 641 move to their original positions. When the partition plates 642 completely enter the inside of the connecting block 63, all the support plates 5 fall onto the limiting plates 641. Therefore, during the movement of the connecting block 63 along the longitudinal beam 4, the movement of the limiting plates 641 and the partition plates 642 is controlled, so that the support plates 5 can be laid in sequence between the two longitudinal beams 4.

[0043] A cavity is defined inside the connecting block 63, a limiting plate 641 and a partition plate 642 are both inserted into the cavity, a driving member comprises a driving gear 643 disposed in the cavity and rotatably connected to the connecting block 63, the driving gear 643 is located between the limiting plate 641 and the partition plate 642, a driving rack meshing with the same driving gear 643 is disposed on the side where the limiting plate 641 and the partition plate 642 are close to each other, a connecting rod 647 is hinged at one end of the limiting plate 641 located in the cavity, a transmission gear 644 is hinged at one end of the connecting rod 647 away from the limiting plate 641, and a hinge point is located at an eccentric point of the transmission gear 644, and the transmission gear 644 is rotatably connected to the connecting block 63.

[0044] The transmission gear 644 rotates and drives the limit plate 641 to slide back and forth through the connecting rod 647. The limit plate 641 drives the driving gear 643 to rotate through the driving rack. The driving gear 643 simultaneously drives another driving rack to move, so that the partition plate 642 and the limit plate 641 move in opposite directions.

[0045] A roller 645 is rotatably connected to the inner wall of the connecting groove, and the roller 645 abuts against the side wall of the longitudinal beam 4. The connecting block 63 is provided with a driving motor 646, and the output shaft of the driving motor 646 is coaxially fixedly connected to the roller 645. A gear set connecting the output shaft and the transmission gear 644 is provided between the two.

[0046] The connecting block 63 is overlapped on the longitudinal beam 4 through the roller 645. When the driving motor 646 drives the roller 645 to rotate, the roller 645 drives the connecting block 63 to move along the direction of the longitudinal beam 4. At the same time, the output shaft of the driving motor 646 drives the transmission gear 644 to rotate, thereby the connecting block 63 lays the support plate 5 downward while moving.

[0047] The implementation principle of Example 2 is: place the connecting block 63 on the longitudinal beam 4, and then drive the motor 646 to drive the connecting block 63 and the storage box 61 to move along the length direction of the longitudinal beam 4. During this process, the partition plate 642 and the limit plate 641 move in opposite directions, so that the support plate 5 is lowered in turn between the two longitudinal beams 4, thereby completing the laying of the support plate 5.

[0048] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
