Abstract
Description
Technical Field
[0001] This utility model relates to the field of industrial kiln technology, and in particular to a movable kiln top channel. Background Technology
[0002] In current industrial kiln applications, operators often need to access the kiln roof for maintenance or work. Because there are no dedicated walkways for operators at the top, they must walk directly on the surface, resulting in concentrated and uneven pressure on the roof. Furthermore, the thermal expansion and contraction caused by temperature changes during daily production gradually leads to fatigue and loosening of the kiln roof's structural materials. Combined with the continuous pressure from operators, this persistent adverse effect gradually weakens the kiln roof's load-bearing capacity, ultimately posing a very high risk of collapse. Utility Model Content
[0003] In response to the problems raised in the background technology, the purpose of this utility model is to propose a movable kiln roof channel, which solves the problem that directly stepping on the kiln roof during the existing kiln production process can easily cause the kiln structure to loosen, posing a significant production safety risk.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0031] The following is in conjunction with the appendix Figures 1 to 6 The technical solution of this utility model will be further illustrated through specific implementation methods.
[0032] A movable kiln top channel includes a horizontal channel plate 1, a number of mounting legs 2 and a number of fixed legs 3;
[0033] Several mounting legs 2 are installed at the bottom of the horizontal channel plate 1, and several fixed legs 3 are fixedly installed on the top of the kiln 0. The mounting legs 2 and the fixed legs 3 are detachably assembled and connected.
[0034] When the mounting leg 2 is assembled and connected with the fixed leg 3, the horizontal channel plate 1 is horizontally positioned above the top 0 of the kiln.
[0035] By installing several mounting legs 2 at the bottom of the horizontal channel plate 1 and several fixed legs 3 at the top of the kiln, the horizontal channel plate 1 forms a passable channel 01 above the kiln roof after the mounting legs 2 and fixed legs 3 are assembled and connected. By setting up the force transmission system of the horizontal channel plate 1 and the legs, the point contact load that was originally applied to the kiln roof by the operator's direct stepping is transformed into a line load that is evenly distributed through multiple legs. The concentrated load generated when the operator walks on the horizontal channel plate 1 is diffused to multiple mounting legs 2 and then transmitted to each fixed leg 3 on the kiln roof, effectively avoiding local crushing.
[0036] The kiln roof passage in this design is a detachable passage 01, allowing it to be installed at different locations on the kiln roof according to actual usage. This resolves the interference issues caused by fixed passages, particularly conflicts with critical areas such as the kiln roof emergency access point. Therefore, this design employs a detachable structure of mounting legs 2 and fixed legs 3. When operation is required on a specific area of the kiln roof (e.g., near the emergency access point), the position of passage 01 can be quickly adjusted, and mounting legs 2 and the original fixed legs 3 can be removed, moved, and installed in other locations. This avoids interference areas and provides sufficient space for maintenance, inspection, and other operations. This not only improves operational convenience but also enables rapid response in emergencies, timely handling of potential kiln roof malfunctions, and increased production efficiency.
[0037] After the horizontal channel plate 1 is installed with the mounting legs 2 and the fixed legs 3 set on the top of the kiln 0, the horizontal channel plate 1 is located above the top of the kiln 0, rather than being directly laid on the top of the kiln 0. This gives the horizontal channel plate 1 a certain vertical isolation space from the top surface of the kiln, forming a forced convection heat dissipation space. This avoids the problem of unprotected contact with the high-temperature surface of the kiln when walking directly through the top of the kiln, which could easily lead to safety accidents.
[0038] In summary, this utility model constructs a dedicated walking passage 01 by setting up a detachable kiln top passage, so that the load of the operator can be transferred to the load-bearing structure of the kiln top through the installation of support legs and fixed support legs system, avoiding the point load concentration caused by direct stepping; and avoiding the high-risk behavior of walking directly on the top of the high-temperature kiln.
[0039] Furthermore, the fixed support 3 is a vertical pipe 30, the lower end of which is welded to the top of the kiln 0, and the vertical pipe 30 extends in the vertical direction;
[0040] The mounting support 2 is a hollow vertical sleeve 20, and the upper end of the vertical sleeve 20 is fixedly connected to the bottom of the horizontal channel plate 1.
[0041] When the mounting leg 2 is assembled and connected with the fixed leg 3, the vertical sleeve 20 is sleeved on the outside of the vertical tube 30.
[0042] The vertical tube 30 and the vertical sleeve 20 adopt a nested fitting design. The inner diameter of the vertical sleeve 20 is 2mm-3mm larger than the outer diameter of the vertical tube 30 to form a guide gap, which ensures the quick assembly of the mounting leg 2 and the fixed leg 3. Compared with other assembly structures that require the assembly of multiple structural components, the vertical sleeve 20 in this solution only needs to be inserted into the vertical tube 30 from top to bottom in the vertical direction to complete the assembly.
[0043] To further explain, the assembly of several mounting legs 2 and fixed legs 3 mutually restricts each other, preventing the passage 01 from moving forward, backward, left, or right, thus improving the safety of the passage 01. In addition, the disassembly direction of the passage 01 (lifting it upward) is opposite to the force exerted by personnel stepping on the passage during use, further ensuring the stability and safety of the passage 01.
[0044] Furthermore, several of the mounting legs 2 are spaced apart along the length extension direction of the horizontal channel plate 1.
[0045] By optimizing the spacing of the mounting legs 2 (recommended spacing 600mm-800mm), a multi-support continuous beam structure is formed. This layout effectively reduces the maximum deflection of the horizontal channel plate 1, avoiding problems such as bending or damage to the horizontal channel plate 1 due to excessive local spacing of the mounting legs 2. It is worth noting that the fixed legs 3 are distributed at different positions on the top 0 of the kiln, which can accommodate the adjustment and movement of the channel 01 to avoid interference. The mounting legs 2 of the channel can be assembled and connected with the fixed legs 3 in other positions.
[0046] Furthermore, the horizontal channel plate 1 includes a horizontal pedal 11 and two right-angle plates 12. The two right-angle plates 12 are respectively located at the bottom of both sides of the horizontal pedal 11. The two right-angle plates 12 are arranged at right angles to each other. The two right-angle plates 12 and the horizontal pedal 11 enclose a bottom-opening receiving space 10. The receiving space 10 is provided with heat insulation cotton 4.
[0047] By placing two right-angled plates 12 at the bottom of both sides of the horizontal step 11, with them facing each other at right angles, a stable support structure is formed (viewed in cross-section), thus significantly enhancing the overall structural stability of the horizontal passageway 1. This design can effectively resist external forces, such as the weight of people walking and possible lateral forces, ensuring the safety and reliability of the passageway.
[0048] Insulating cotton 4 is installed within the accommodating space 10 formed by the horizontal footplate 11 and two right-angle plates 12 at the bottom opening, effectively improving the heat insulation effect of the passage. As a highly efficient heat insulation material, insulating cotton 4 prevents heat from being transferred from the kiln roof to the passage surface, reducing the surface temperature and providing operators with a more comfortable and safer working environment. The addition of insulating cotton 4 not only improves heat insulation performance but also plays a role in fire prevention and flame retardancy to a certain extent. In the environment of the kiln roof, where high temperatures and ignition sources may exist, the flame-retardant properties of insulating cotton 4 provide additional safety for operators.
[0049] To further explain, the receiving space 10 with the bottom opening makes the installation, inspection, and replacement of the insulation 4 relatively easy. Operators can easily access the receiving space 10 through the opening to perform necessary maintenance or replacement of the insulation 4 without large-scale disassembly or modification of the entire channel structure.
[0050] Furthermore, the right-angle plate 12 includes a right-angle vertical plate 121 and a right-angle horizontal plate 122. One side of the right-angle vertical plate 121 is connected to one side of the right-angle horizontal plate 122, and the other side of the right-angle vertical plate 121 is connected to the horizontal pedal 11. The right-angle horizontal plate 122 is parallel to the horizontal pedal 11.
[0051] Several mounting feet 2 are respectively located at the bottom of the two right-angled horizontal plates 122.
[0052] The right-angle plate 12 is subdivided into right-angle vertical plates 121 and right-angle horizontal plates 122, which are connected to form a stable right-angle structure, further enhancing the overall strength and stability of the horizontal channel plate 1. This allows the horizontal channel plate 1 to withstand greater loads and impacts, improving its durability and safety.
[0053] By using the right-angle horizontal plate 122, the stress that might have been concentrated at the connection between the right-angle vertical plate 121 and the horizontal pedal 11 is distributed over a larger area, reducing stress concentration and thus lowering the risk of material fatigue and damage caused by stress concentration. Furthermore, the right-angle horizontal plate 122 increases the sealing of the receiving space 10. After the insulation cotton 4 is installed in the receiving space 10, it is supported by the right-angle horizontal plate 122 on both sides of its bottom, effectively preventing the insulation cotton 4 from falling off during stepping or vibration.
[0054] By placing the mounting feet 2 at the bottom of the right-angle horizontal plate 122 (equivalent to the bottom sides of channel 01), greater flexibility is provided for the installation and adjustment of channel 01. This design allows channel 01 to be precisely positioned and fixed according to actual needs, while also facilitating future maintenance and replacement.
[0055] Furthermore, several of the mounting legs 2 are spaced apart along the length extension direction of the horizontal channel plate 1.
[0056] The mounting feet 2 are spaced apart along the length of the horizontal channel plate 1, providing multi-point support for the entire channel 01 along its length. This multi-point support design effectively distributes the load borne by the channel 01, enhances its stability in all directions, and prevents deformation or damage caused by excessive force at a single point.
[0057] The spaced mounting feet 2 increase the contact area between the passage 01 and the kiln roof, thereby improving the load-bearing capacity of the entire passage. This allows the passage to withstand greater personnel and equipment loads, meeting more diverse usage needs.
[0058] Furthermore, the horizontal channel plate 1 also includes a reinforcing steel 13, which extends along the width direction of the horizontal tread 11, and the two sides of the reinforcing steel 13 are respectively connected to the right angle plates 12 on both sides.
[0059] The addition of reinforcing steel 13, extending particularly along the width of the horizontal tread 11 and connecting with the right-angle plates 12 on both sides, provides an additional support frame for the horizontal passageway 1. The tight connection between the reinforcing steel 13, the right-angle plates 12, and the horizontal tread 11 forms a more stable triangular support structure (reflected in both the cross-section and longitudinal direction). This design improves the overall stability of the passageway 01, preventing safety hazards caused by deformation or torsion. This significantly enhances the overall structural strength of the passageway, enabling it to withstand greater loads and impacts, thus improving its durability and reliability.
[0060] The reinforcing steel 13 not only increases the rigidity of channel 01 but also helps optimize stress distribution. Under load, the reinforcing steel 13 effectively disperses stress, preventing material fatigue and failure caused by stress concentration. This helps extend the service life of the channel and reduce maintenance costs. Furthermore, in some cases, the channel may be subjected to accidental impacts or collisions. The addition of reinforcing steel 13 improves the channel's impact resistance, reducing damage and safety accidents caused by impacts.
[0061] Furthermore, several of the reinforcing steels 13 are spaced apart along the length extension direction of the horizontal pedal 11.
[0062] The reinforcing steel 13 is spaced apart along the length of the horizontal tread 11, which can evenly distribute stress along the length of the horizontal channel plate 1. When the horizontal channel plate 1 is under load, this design can effectively prevent stress concentration, reduce deformation or damage caused by excessive force at a single point, and improve the overall strength and stability of the channel 01.
[0063] The spaced reinforcing steel 13 enhances the bending resistance of the horizontal channel plate 1. Under lateral loads or impacts, the reinforcing steel 13 resists bending deformation, maintaining the straightness and stability of the channel and ensuring its safe use.

These descriptions are merely for explaining the principles of this utility model and should not be construed as limiting the scope of protection of this utility model in any way. Based on this explanation, those skilled in the art can readily conceive of other specific embodiments of this utility model without any inventive effort, and these embodiments will all fall within the scope of protection of this utility model.
