Description

Technical Field

[0001] This utility model relates to the field of kiln car technology, specifically a novel tunnel kiln car. Background Technology

[0002] A tunnel kiln is a continuous thermal equipment widely used in firing or heat treatment processes in industries such as ceramics, refractory materials, bricks and tiles, metallurgy, and chemicals. The kiln car is a transport device used inside the tunnel kiln to carry products. The kiln car is used in a cycle on the track of the tunnel kiln to transport the products to be fired from outside the kiln into the kiln. After passing through the preheating zone, firing zone, and cooling zone, the products are fired and then transported out of the kiln.

[0003] Announcement No. CN220018127U discloses a layered tunnel kiln car. This patent addresses the shortcomings of existing layered kiln cars, which lack a structure for protecting and stabilizing materials in the upper layer, making it difficult to ensure the stability of the upper layer materials and causing them to easily tip over and fall during transportation. By setting a combination of hydraulic rods and sleeved springs between the upper and lower partitions, the hydraulic damping absorbs vertical impact energy, while the springs provide static support force, achieving basic shock absorption during transportation. Protective side plates of fixed height are added to both sides of the upper partition to form physical barrier boundaries, preventing lateral slippage of materials and thus improving the stability of materials during transportation.

[0004] However, the height of the protective side plate is fixed and cannot be adjusted. When the height of the transported material exceeds the height of the side plate, the top of the material is prone to slipping off the side plate due to centrifugal inertia or sudden stop of the kiln car. The slipping material may hit the hydraulic system of the kiln car or the track sensor, causing equipment failure and shutdown, affecting the yield of the entire batch of products. Therefore, a new type of tunnel kiln car is proposed to solve the above problems. Utility Model Content

[0015] 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.

[0016] Please see Figure 1-5 A novel tunnel kiln car in this embodiment includes a kiln car bottom plate 1, a lower placement plate 2 and an upper placement plate 3. Two first protective side plates 4 are fixedly installed on the surface of the lower placement plate 2, and two second protective side plates 5 are fixedly installed on the surface of the upper placement plate 3. An adjustable protective structure 6 is provided on the second protective side plate 5. The adjustable protective structure 6 includes two sleeves 61 fixedly installed on the surface of the second protective side plate 5. A top spring 62 is fixedly installed inside the sleeve 61. A connecting top rod 63 extending out of the sleeve 61 is fixedly installed on the top of the top spring 62. A protective railing 64 is fixedly installed on the top of the connecting top rod 63. A connecting frame 65 is fixedly installed at the bottom of the protective railing 64. An elastic buckle 66 is rotatably installed inside the connecting frame 65. A strip groove 67 is opened on the surface of the upper placement plate 3. A locking rod 68 is fixedly installed between the opposite surfaces inside the strip groove 67. A shock-absorbing support assembly 7 is provided between the opposite surfaces of the kiln car bottom plate 1 and the lower placement plate 2.

[0017] In this embodiment, the guardrail 64 has a hollow structure. A tension spring 641 is fixedly installed inside the guardrail 64. A steel wire rope 642 extending to the top of the guardrail 64 is fixedly installed at one end of the tension spring 641. A hook 643 is fixedly installed at the end of the steel wire rope 642 away from the tension spring 641. By setting a retractable steel wire rope 642, when the object placed on the upper placement plate 3 is high, the steel wire rope 642 can be used to bind and lock the object, which can prevent the object from shaking on the upper placement plate 3 and improve the stability of the object on the upper placement plate 3. The tension spring 641 between the steel wire rope 642 and the guardrail 64 can realize the storage of the steel wire rope 642, and at the same time, it can prevent the steel wire rope 642 from being too tight and causing wear on the surface of the object.

[0018] In this embodiment, both ends of the first protective side plate 4 and the second protective side plate 5 are provided with protective end plates 8. One side of the protective end plate 8 is rotatably connected to one end of one of the first protective side plate 4 or the second protective side plate 5, and the other side of the protective end plate 8 is snapped into one end of the other first protective side plate 4 or the second protective side plate 5. By setting the protective end plates, it is beneficial to prevent items on the kiln car from sliding off from both ends of the kiln car.

[0019] In this embodiment, a buckle is provided on one side of the protective end plate 8, and a slot corresponding to the buckle is provided at one end of the first protective side plate 4 or the second protective side plate 5, so as to facilitate the fixed connection of the protective end plate 8 with the first protective side plate 4 and the second protective side plate 5.

[0020] In this embodiment, the shock-absorbing support assembly 7 includes a hydraulic rod 71 and a spring 72 fixedly installed on the upper surface of the kiln car bottom plate 1. A telescopic protective sleeve 73 is fixedly installed between the opposite surfaces of the kiln car bottom plate 1 and the lower placement plate 2. The spring 72 is sleeved on the outside of the hydraulic rod 71, and the hydraulic rod 71 and the spring 72 are located inside the telescopic protective sleeve 73. By setting the shock-absorbing support assembly, it can play a shock-absorbing and buffering role during the operation of the kiln car, protecting the items and the kiln car structure.

[0021] In this embodiment, there are multiple locking rods 68, and grooves 9 are provided on the opposite side surface of the elastic buckle 66. The distance between two adjacent locking rods 68 is adapted to the thickness of the elastic buckle 66, and the locking rods 68 are adapted to the grooves 9.

[0022] In this embodiment, the surfaces of the first protective side plate 4, the second protective side plate 5, and the protective end plate 8 are all provided with a number of evenly distributed strip holes, and the surface of the upper placement plate 3 is provided with a number of evenly distributed through holes. The upper placement plate 3 is fixedly installed on the top of the first protective side plate 4.

[0023] The working principle of the above embodiments is as follows: When placing items, the protective end plate 8 can be rotated open. After placement, the protective end plate 8 is snapped in place. When the height of the protective railing 64 needs to be adjusted, press down on the protective railing 64. The connecting top rod 63 will compress the top spring 62 and retract into the sleeve 61. At this time, the protective railing 64 can be adjusted to a suitable position according to the height of the item. After adjusting the height of the protective railing 64, rotate the elastic buckle 66 so that the elastic buckle 66 is snapped between two adjacent locking rods 68. At the same time, the locking rods 68 are embedded in the groove 9, thereby fixing the protective railing 64. When the object is high, pull the steel wire ropes 642 on both sides out from inside the protective railing 64 and hook the hooks 643 of the steel wire ropes 642 on both sides together to limit and bind the object, thereby improving the stability of the object placement. When the kiln car encounters bumps or vibrations during operation, the lower placement plate 2 will be impacted and tend to move up and down. At this time, the spring 72 will undergo elastic deformation, absorbing some of the impact energy and playing a preliminary buffering role; at the same time, the hydraulic rod 71 will further buffer and stabilize the movement of the lower placement plate 2 through its internal hydraulic system, preventing the lower placement plate 2 from generating excessive vibration amplitude, thereby protecting the items placed on the lower placement plate 2 and the upper placement plate 3 from damage. The telescopic protective sleeve 73 can prevent dust, debris and other objects from entering the hydraulic rod 71 and the spring 72.

[0024] All electrical components mentioned in the text are electrically connected to the main controller and power supply. The main controller can be a conventional and known device such as a computer, and the existing publicly available power connection technology will not be elaborated in the text.
