Description

Technical Field

[0001] This utility model relates to the field of grate technology, and in particular to a grate bar and load-bearing beam structure that can be detached separately. Background Technology

[0002] Grate bars are components in boilers or industrial furnaces used to hold solid fuels and ensure their efficient combustion. Their main function is to support and propel the fuel bed forward, thereby ensuring a continuous supply and combustion of fuel.

[0003] In existing grate structures, such as the high-pressure grate structure device for waste incinerators disclosed in patent CN207049943U, the grate bars are arranged in a stacked manner, and the grate bars are connected to the load-bearing beam by bolt assemblies. When the grate bars are worn or broken, they need to be disassembled and replaced.

[0004] However, if the damage doesn't occur in the first row of grate bars, replacing the damaged grate bar requires starting from the first row and dismantling until the damaged one is found. After replacement, the grate bars are then reinstalled row by row in the reverse direction of dismantling. Therefore, this method of grate bar dismantling and reinstallation is extremely time-consuming and labor-intensive, severely impacting normal production progress and thus requiring improvement. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model discloses a separately detachable grate plate and supporting beam structure, including a grate plate body and a supporting beam body. The grate plate body includes a working surface, a support portion extending downward from the front end of the working surface, a positioning seat extending downward from the rear end of the working surface, and a connecting portion located near the middle of the bottom of the working surface. The supporting beam body includes an I-beam, an extension arm located at the front end of the I-beam, a through hole located on the positioning seat, and a bolt hole located at the top of the I-beam corresponding to the through hole. The through hole and the bolt hole are connected by bolts. Multiple limiting blocks are located on the inner side of the bottom end of the connecting portion, and an anti-tilting plate is located at the front end of the extension arm. The limiting blocks are engaged with the bottom of the anti-tilting plate.

[0006] Furthermore, the inner diameter of the through hole is larger than the outer diameter of the bolt.

[0007] Furthermore, the front end of the support portion is provided with an auxiliary disassembly hole along the lateral direction.

[0008] Compared with the prior art, the beneficial effects of this utility model are:

[0009] This utility model connects the grate plate body to the rear end of the supporting beam body with bolts, and engages with the anti-tilting plate through a limiting block, so that the grate plate body can be disassembled individually without having to be disassembled in sequence, thereby improving the maintenance efficiency of the grate plate.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0017] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0018] Furthermore, the use of terms such as "first" and "second" in this utility model is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features.

[0019] In the description of the embodiments, unless otherwise expressly specified and limited, the terms "set," "connect," etc., should be interpreted broadly. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or a connection through an intermediate medium, or it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0020] like Figure 1-2 As shown, the separately detachable grate plate and supporting beam structure in this embodiment includes a grate plate body and a supporting beam body. The grate plate body includes a working surface 1 for supporting the movement of fuel; a support part 2 extends downward from the front end of the working surface 1 for supporting the working surface 1 of the adjacent grate plate body; a positioning seat 3 extends downward from the rear end of the working surface 1; and a connecting part 4 is provided at the bottom of the working surface 1 near the middle.

[0021] The supporting beam body includes an I-beam 5, with an extension arm 6 at the front end. A through hole 7 is provided on the positioning seat 3. A bolt hole 8 is provided at the top of the I-beam 5 corresponding to the through hole 7. The through hole 7 and the bolt hole 8 are connected by bolts 9, used to fix the grate body and the rear end of the supporting beam body, preventing the grate body from swaying left and right during movement and controlling the gap between the grate bodies. The inner diameter of the through hole 7 is larger than the outer diameter of the bolt 9, ensuring that the bolt 9 can pass smoothly through the through hole 7; specifically, the inner diameter of the through hole 7 can be set to 18mm, and the bolt 9 can be a standard M16 bolt.

[0022] Multiple limiting blocks 10 are provided on the inner side of the bottom end of the connecting part 4, and an anti-tilting plate 11 is provided at the front end of the extension arm 6. The limiting blocks 10 are snapped into the bottom of the anti-tilting plate 11.

[0023] The front end of the support part 2 is provided with an auxiliary disassembly hole 12 along the lateral direction to facilitate the disassembly of the grate plate body. The auxiliary disassembly hole 12 can be either a through hole or a blind hole.

[0024] like Figure 3 As shown, when this utility model is used, several grate plates are stacked together in sequence. The grate plate body is connected to the rear end of the supporting beam body by bolts 9. The middle part is connected to the anti-tilting plate 11 by a limiting block 10. The limiting block 10 can prevent the front end of the grate plate body from swaying left and right, and plays a positioning and distance-fixing role. The anti-tilting plate 11 can prevent the grate plate body from tilting upward.

[0025] When the incinerator and other equipment move the load-bearing beam forward, the bolts 9 and the limit blocks 10 can provide forward thrust, thereby driving the grate body forward; when the load-bearing beam moves backward, the bolts 9 provide backward tension, thereby driving the grate body backward.

[0026] When one of the grate bars is damaged and needs to be disassembled, the bolts 9 on the grate bar body can be removed first. Then, a tool can be inserted into the auxiliary disassembly hole 12 to slightly lift the upper grate bar body by about 1mm. In this way, the damaged grate bar body can be slid out diagonally upward along the lower grate bar body, thereby achieving the disassembly of the damaged grate bar body.

[0027] The new grate body can be pushed in along the gap created by the damaged grate body, so that the through hole 7 is aligned with the bolt hole 8, and the limit block 10 is locked at the bottom of the anti-tilting plate 11. Then, the grate body and the load-bearing beam body are connected together with the bolt 9, thereby completing the replacement of the grate body.

[0028] This invention allows for the individual disassembly and replacement of a damaged grate plate without the need for sequential disassembly, effectively shortening working hours and improving the maintenance efficiency of the grate plates.

[0029] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model. Furthermore, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the protection scope claimed by this utility model.
