Technical Field

[0001] This utility model relates to the field of coal loading technology, specifically to a bin wall inspection door and a large-span single-bin double-track loading station using the same. Background Technology

[0002] In warehousing, mining, and grain processing, various types of warehouses (such as storage silos, buffer silos, and transfer silos) are the core equipment for the temporary storage and transfer of materials. To ensure the long-term stable operation of the warehouses, regular inspections and maintenance of the interior are required. Therefore, inspection doors are usually installed on the warehouse walls for operators to enter and exit or for tools to be inserted for work.

[0003] The existing warehouse wall access doors and connecting structures are mostly simple flat plates fixed with bolts. The flat plate is fixed at the warehouse wall access port with bolts. In actual installation, the position of the flat plate and the warehouse wall access port must be repeatedly adjusted to achieve the alignment of the bolt holes, resulting in low installation efficiency. Utility Model Content

[0004] To address the technical problems existing in the background art, this utility model provides a warehouse wall inspection door and a large-span single-warehouse double-track loading station using the same.

[0005] The technical solution of this utility model is as follows: A warehouse wall inspection door includes an inspection passage and a sealing plate disposed on its outer side. The inspection passage has an installation plate on its outer periphery, and the installation plate has several installation holes. The sealing plate has an insertion hole on its outer ring corresponding to the installation holes, and its center is recessed to form a concave part that can be inserted into and cooperate with the inner wall of the inspection passage. The interior of the concave part is provided with a handle.

[0006] Furthermore, the cross-sectional shape of the maintenance access passage is rectangular.

[0007] Furthermore, the grip is perpendicular to the insertion direction of the concave portion.

[0008] Preferably, at least two grips are provided at intervals.

[0009] Furthermore, a rubber pad is provided between the mounting plate and the sealing plate, and an avoidance through hole is provided on the pad corresponding to the mounting hole.

[0010] Preferably, the maintenance passage is a cylindrical structure formed by bending and butt welding a single plate. The concave part includes a rectangular base plate and four side plates on its outer ring, and adjacent side plates are welded together.

[0011] This utility model also provides a large-span single-compartment double-track loading station, including a compartment body and an inspection device provided on the outer wall of the compartment body. The inspection device is a compartment wall inspection door as described above, and the end of the inspection channel away from the sealing plate is connected to the interior of the compartment body.

[0012] Furthermore, the top surface of the concave portion is flush with the inner wall of the compartment.

[0013] As one implementation method, a protective component is provided on the upper side of the outer wall of the warehouse corresponding to the maintenance device. The lower side of the protective component is open and covers the maintenance device.

[0014] As a further implementation, the outer wall of the warehouse is provided with a storage device on the lower side corresponding to the maintenance device, and an upward-facing receiving groove is provided on the upper side of the storage device.

[0015] The beneficial effects of this utility model are as follows: by providing an insertion guide for the recessed part of the sealing plate through the maintenance channel, the insertion hole of the sealing plate can be automatically aligned with the mounting hole of the mounting plate, eliminating the need for repeated hole adjustments as required by traditional flat maintenance doors, thus significantly shortening the installation time; moreover, the fit between the recessed part and the maintenance channel not only improves the installation positioning accuracy of the sealing plate, but also reduces the seepage of material dust from the gap between the maintenance channel and the sealing plate; at the same time, the handle is located on the side of the recessed part away from the silo body, making it convenient for operators to apply force when opening and closing the sealing plate, further optimizing the convenience of maintenance operations.

Detailed Implementation

[0017] Combination Figure 1 This embodiment provides a large-span single-compartment double-track loading station, including a compartment 1, a maintenance device 2 disposed on the outer wall of the compartment 1, a protective component 3 disposed on the upper side of the maintenance device 2 on the outer wall of the compartment 1, and a storage component 4 disposed on the lower side of the maintenance device 2 on the outer wall of the compartment 1.

[0018] It should be noted that the large-span single-compartment double-track loading station can adopt existing technologies, such as the double-track single-line loading system disclosed in patent publication number CN202007040U. The compartment 1 can be any compartment 1 on the large-span single-compartment double-track loading station, such as a storage compartment, buffer compartment, transfer compartment, etc. The maintenance device 2 is designed for the compartment 1 to prevent the difficulty of clearing the blockage after the material in the compartment 1 is blocked, and to facilitate the clearing and maintenance of the compartment 1.

[0019] Combination Figure 3 The lower opening of the protective component 3, which covers the maintenance device 2, can prevent materials (such as coal blocks and ore) or maintenance tools from falling during loading operations from hitting the maintenance device 2, thus avoiding deformation or damage to the components. At the same time, the protective component 3 can shield the maintenance device 2 from rainwater and dust, reduce the risk of rust, and extend the overall service life of the maintenance device 2.

[0020] The upper side of the storage unit 4 is provided with an upward-facing receiving slot, which can be used to place maintenance tools (such as screwdrivers, wrenches) or small parts such as removed bolts, so that operators do not need to go back and forth to retrieve tools, reducing the ineffective time in the maintenance process, further improving maintenance efficiency, and ensuring the cleanliness and orderliness of the maintenance work site.

[0021] As one implementation method, both the placement component 4 and the protective component 3 are made of H-shaped channel steel (such as...). Figure 3 (As shown).

[0022] For maintenance device 2, combined with Figure 2 and Figure 3 For example, the maintenance device 2 includes a maintenance channel 21 and a sealing plate 24 located on its outer side. The maintenance channel 21 has an installation plate 22 on its outer periphery, and the installation plate 22 has a plurality of installation holes. The sealing plate 24 has an insertion hole on its outer ring corresponding to the installation holes, and its middle part is recessed to form a concave part 23 that is inserted and matched with the inner wall of the maintenance channel 21. The interior of the concave part 23 is provided with a handle 25.

[0023] The maintenance channel 21 of the maintenance device 2, at one end away from the sealing plate 24, is connected to the interior of the silo 1. In use, the maintenance channel 21 can provide an insertion guide for the recessed portion 23 of the sealing plate 24, so that the insertion hole of the sealing plate 24 can automatically align with the mounting hole of the mounting plate 22. Unlike traditional flat maintenance doors, there is no need to repeatedly adjust the hole position, which greatly shortens the installation time. The fit between the recessed portion 23 and the maintenance channel not only improves the installation positioning accuracy of the sealing plate 24, but also reduces the seepage of material dust from the gap between the maintenance channel and the sealing plate 24. At the same time, the handle 25 is located inside the recessed portion 23, that is, on the side away from the silo 1, which makes it convenient for the operator to apply force when opening and closing the sealing plate 24, further optimizing the convenience of maintenance operations.

[0024] A rubber pad 26 is provided between the mounting plate 22 and the sealing plate 24. A clearance through hole is provided on the rubber pad corresponding to the mounting hole. The rubber pad 26 achieves a complete circumferential seal between the mounting plate 22 and the sealing plate 24, effectively preventing material dust in the silo 1 from leaking from the gap between the mating surfaces. At the same time, the rubber pad 26 can also buffer the impact of the loading device vibration on the connection structure between the mounting plate 22 and the sealing plate 24, reducing the risk of bolt loosening.

[0025] The cross-sectional shape of the maintenance channel 21 is rectangular, which makes the concave part 23 fit and fit tightly with the rectangular cross-section of the maintenance channel. The asymmetric characteristics of the rectangular structure can limit the circumferential rotation of the sealing plate 24 relative to the maintenance channel, and prevent the sealing plate 24 from shifting or the insertion hole and installation hole from being misaligned due to vibration of the loading device. Compared with the circular cross-section (which is easy to rotate), this further improves the assembly stability of the maintenance device 2. At the same time, the tightly fitted inner wall can also reduce the seepage of material dust from the gap, and help enhance the sealing effect.

[0026] The insertion direction of the handle 25 is perpendicular to that of the recess 23, so that the direction of force applied by the operator when opening and closing the sealing plate 24 is consistent with the direction of movement of the sealing plate 24, avoiding strenuous operation or jamming of the sealing plate 24 due to deviation of the direction of force application; at the same time, the vertical handle 25 is more ergonomically designed, allowing the operator to hold it naturally and apply force, reducing hand fatigue and improving the comfort and stability of maintenance operations.

[0027] The grip bar 25 has at least two bars spaced apart, which can be used with both hands when installing and removing it, avoiding bending, deformation or falling off of a single grip bar 25 due to concentrated force, thus extending the service life of the grip bar 25; in addition, multiple grip bars 25 can also adapt to different operating scenarios, such as two-person collaborative operation.

[0028] The top surface of the concave portion 23 is flush with the inner wall of the silo body 1, that is, the inner side of the concave portion 23 facing the silo body 1 is flush with the inner side wall of the silo body 1, so as to avoid material being stuck on the upper side of the concave portion 23. At the same time, the flush inner side can reduce the scouring and wear of the material on the sealing plate 24 and extend the service life of the sealing plate 24.

[0029] The maintenance passage 21 is a rectangular cylindrical structure formed by bending and butt welding a single plate. Compared with the structure of splicing multiple plates, it reduces the splicing gaps and improves the overall sealing of the maintenance passage 21. The structure of bending a single plate has higher strength, stronger resistance to deformation, and relatively simpler processing technology.

[0030] Mounting plate 22 is an annular plate, and its inner ring is welded to the end edge of the inspection channel 21.

[0031] The recessed portion 23 includes a rectangular base plate and four side plates on its outer ring, and the adjacent side plates are welded together. This not only makes the processing technology convenient, but also ensures that the recessed portion 23 can stably block the maintenance passage.

[0032] Combination Figure 2 and Figure 3 The distance between the inner side of the mounting plate 22 and the outer wall of the chamber 1 is set to allow a person's hand to reach in. During installation, the bolt is inserted from the mounting hole between the inner side of the mounting plate 22 and the outer wall of the chamber 1, and then passed through the clearance hole and the insertion hole in sequence. Finally, the locking nut is tightened on the bolt extending out of the outer side of the sealing plate 24 to fix the sealing plate 24. The bolts and tools used in this process can be placed in the receiving groove before and after disassembly for easy access.
