[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0020] Example 1
[0021] Please see Figure 1-4 The present invention provides the following technical solution: a limiting device for loading and unloading kiln cars, including a bottom box 2, the bottom box 2 is set inside the ground 5, a kiln car body 1 is set above the bottom box 2, and a plurality of movable wheels 6 are fixedly installed below the kiln car body 1 and above the bottom box 2. The kiln car body 1 and the bottom box 2 are connected by a limiting fixing device 3, and the bottom box 2 is connected to the ground 5 by two installation connecting devices 4.
[0022] Specifically, the limiting and fixing device 3 includes a first motor 31, a first lead screw 32, a lifting block 33, a lifting plate 34, a fixing component 35, and a friction rubber plate 36. The first motor 31 is fixedly installed on the inner side of the base box 2. The first lead screw 32 is fixedly installed below the output end of the first motor 31. The lifting plate 34 is threadedly installed on the outer side of the first lead screw 32 and on the inner side of the base box 2. Two lifting blocks 33 are fixedly installed on the upper part of the lifting plate 34 and between the two sides of the first motor 31 and the multiple moving wheels 6. The friction rubber plate 36 is fixedly installed on the upper part of the lifting blocks 33 and below the kiln car body 1. The fixing component 35 is provided on the top of the two lifting blocks 33.
[0023] By adopting the above technical solution, the staff can increase the movement resistance of the kiln car body 1 by cooperating with the first motor 31 and friction rubber plate 36 when needed, thereby limiting the kiln car body 1 and ensuring the normal loading and unloading of air-dried blanks on the kiln car body 1.
[0024] Specifically, the shape and size of the inner cross-section of the base box 2 are the same as the shape and size of the outer cross-section of the lifting plate 34.
[0025] By adopting the above technical solution, the device can ensure that the inner side of the base box 2 and the outer side of the lifting plate 34 fit together, thereby preventing the lifting plate 34 from shifting during movement and ensuring the normal operation of the work.
[0026] Specifically, the fixing component 35 includes a limiting block 351, an insert block 352, a connecting box 353, and an electric telescopic rod 354. The limiting block 351 is fixedly installed below the kiln car body 1 and between the two friction rubber plates 36. The connecting box 353 is fixedly installed on the top of the lifting block 33. The electric telescopic rod 354 is fixedly installed on the inner side of the connecting box 353. The insert block 352 is fixedly installed on the side of the electric telescopic rod 354 near the limiting block 351.
[0027] By adopting the above technical solution, the staff can fix the kiln car body 1 by using the cooperation of structures such as the limiting block 351 and the insert block 352 when needed, thereby better meeting the needs of the work.
[0028] In this embodiment, when the kiln car 1 needs to be limited due to the loading and unloading of air-dried blanks, an external power source is connected. When the kiln car 1 moves to the bottom box 2 in the ground 5 via the various moving wheels 6, the operator starts the first motor 31 in the limiting and fixing device 3. The first motor 31 drives the first lead screw 32 to rotate. The first lead screw 32 is threadedly connected to the lifting plate 34, and the outer side of the lifting plate 34 is in contact with the inner side of the bottom box 2. Therefore, the first lead screw 32 drives the lifting plate 34 to rise, which in turn drives the two lifting blocks 33 to rise until the friction rubber plates 36 on the two lifting blocks 33 are in close contact with the kiln car 1, thereby increasing the movement resistance of the kiln car 1. Then, the electric telescopic rod 354 in the two fixing components 35 is activated, thereby driving the two insert blocks 352, which were originally in the two connecting boxes 353, to insert into the limiting block 351 under the kiln car 1, thereby limiting and fixing the kiln car 1. Then, the loading and unloading of air-dried blanks can be carried out.
[0029] Example 2
[0030] The difference between this embodiment and embodiment 1 is that the installation and connection device 4 includes a second motor 41, a movable plate 42, a connecting block 43, a connecting sleeve 44, a second lead screw 45, and a fixing box 46. The fixing box 46 is fixedly installed on the inner side of the ground 5 and on both sides of the base box 2. The second motor 41 is fixedly installed on the inner side of the fixing box 46. The second lead screw 45 is fixedly installed on the side of the output end of the second motor 41 near the base box 2. The movable plate 42 is threadedly installed on the outer side of the second lead screw 45 and on the inner side of the fixing box 46. Two connecting sleeves 44 are fixedly installed on both sides of the base box 2 near the edge. Two connecting blocks 43 are fixedly installed on the side of the movable plate 42 near the two connecting sleeves 44 and on the inner side of the two connecting sleeves 44.
[0031] By adopting the above technical solution, the staff can assist in loading and unloading the bottom box 2 and other limiting structures when needed by using the cooperation of connecting block 43 and connecting sleeve 44, thereby reducing the difficulty of loading and unloading and alleviating the workload of the staff.
[0032] Specifically, the inner side of the fixed box 46 and the outer side of the movable plate 42 are fitted together.
[0033] By adopting the above technical solution, the device can limit the movement of the moving plate 42 by the fixed box 46, thereby preventing the moving plate 42 from deviating during the movement and ensuring the normal operation of the work.
[0034] In this embodiment, when it is necessary to disassemble the base box 2 and other structures, the workers start the second motors 41 in the two installation and connection devices 4 respectively, thereby driving the two second lead screws 45 to rotate. The second lead screws 45 are threadedly connected to the moving plate 42, and the outer side of the moving plate 42 is in contact with the inner side of the fixed box 46. Therefore, the two second lead screws 45 drive the two moving plates 42 to move, thereby driving each connecting block 43 to disengage from each connecting sleeve 44 on the base box 2. Then, the workers take the base box 2 and other structures out of the ground 5. After disassembly, when it is necessary to install the base box 2 and other structures, the workers put the base box 2 and other structures into the ground 5, and then start the two second motors 41 in reverse, thereby driving each connecting block 43 to insert into each connecting sleeve 44 on the base box 2. After installation, it is convenient for the workers to carry out loading and unloading work.
[0035] The working principle and usage process of this utility model are as follows: When the kiln car body 1 needs to be limited due to the loading and unloading of air-dried blanks, an external power supply is connected. When the kiln car body 1 moves to the bottom box 2 in the ground 5 via each moving wheel 6, the operator starts the first motor 31 in the limiting and fixing device 3. The first motor 31 drives the first lead screw 32 to rotate. The first lead screw 32 is threadedly connected to the lifting plate 34, and the outer side of the lifting plate 34 is in contact with the inner side of the bottom box 2. Therefore, the first lead screw 32 drives the lifting plate 34 to rise, which in turn drives the two lifting blocks 33 to rise until the friction rubber plates 36 on the two lifting blocks 33 are in close contact with the kiln car body 1, thereby increasing the moving resistance of the kiln car body 1. Then, the electric telescopic rod 354 in the two fixing components 35 is activated, thereby driving the two insert blocks 352 originally in the two connecting boxes 353 to insert into the limiting block 351 under the kiln car body 1, thereby controlling the kiln. After the furnace car body 1 is fixed in place, the air-dried blanks can be loaded and unloaded. When it is necessary to disassemble the bottom box 2 and other structures, the workers start the second motors 41 in the two installation and connection devices 4, which drives the two second lead screws 45 to rotate. The second lead screws 45 are threadedly connected to the moving plate 42, and the outer side of the moving plate 42 is in contact with the inner side of the fixed box 46. Therefore, the two second lead screws 45 drive the two moving plates 42 to move, thereby causing each connecting block 43 to disengage from each connecting sleeve 44 on the bottom box 2. Then, the workers take the bottom box 2 and other structures out of the ground 5. After disassembly, when it is necessary to install the bottom box 2 and other structures, the workers put the bottom box 2 and other structures into the ground 5, and then start the two second motors 41 in reverse, which drives each connecting block 43 to insert into each connecting sleeve 44 on the bottom box 2. After installation, it is convenient for the workers to carry out loading and unloading work.
