Description

Technical Field

[0001] This utility model relates to the field of tobacco processing equipment technology, specifically to a portable maintenance platform for tobacco processing tube equipment. Background Technology

[0002] Currently, tobacco processing enterprises use various types of tubular equipment in their tobacco processing production, such as loosening and rehydration machines, leaf feeders, and tobacco drying machines. When a production task is completed or a new grade needs to be changed during production, operators must clean the inside of these tubular equipment. Additionally, when components such as lifting plates, rakes, or nozzles malfunction inside the tubular equipment, maintenance personnel must enter the equipment to perform repairs.

[0003] Vibrating conveyors are installed at the discharge end of cylindrical equipment such as loosening and rehumidifying machines, leaf feeders, and tobacco drying machines to transport tobacco materials after processing. When operators or maintenance personnel perform maintenance work on cylindrical equipment, they usually first climb onto the vibrating conveyor via a mobile staircase, and then step over the vibrating conveyor to enter the cylindrical equipment. This method of entry requires stepping on the side or surface of the vibrating conveyor trough and the inner wall of the cylinder. Since there is a certain distance between the side of the vibrating conveyor trough and the inner wall of the cylinder, and the surface of the vibrating conveyor trough is smooth, operators and maintenance personnel are prone to bumping, slipping, or tripping when entering the cylinder, which poses certain safety hazards.

[0017] The specific implementation of this embodiment will now be described with reference to the accompanying drawings.

[0018] A portable maintenance platform for tobacco processing tube equipment, referring to Figure 1 and Figure 2The system includes a pedal body 1, with a straight plate 92 fixedly mounted on the front side of the pedal body 1. A connecting hinge 6 is fixedly mounted on the straight plate 92. A pair of rod-shaped overlapping hooks 2 are fixed to the front side wall of the connecting hinge 6. A pair of L-shaped plates 9 are invertedly mounted on both sides of the pedal body 1. An overlapping plate 3 is fixedly mounted on the rear side of the pedal body 1. An overlapping interface 4 is opened at the junction of the overlapping plate 3 and the L-shaped plate 9. Through the overall structural design, a rigid channel is formed across the gap between the cylinder and the vibrating conveyor, completely replacing the risky operation of stepping on the sidewall of the original trough. The synergistic effect of the overlapping hooks 2 and the overlapping interface 4 anchors both ends of the platform to the outer edge 8 of the inner wall of the cylinder and the sidewall of the vibrating conveyor trough 7, respectively, providing a stable support surface. The L-shaped plate 9 enhances the edge deformation resistance of the pedal body 1 and prevents it from tipping over. The connecting hinge 6 allows the overlapping hooks 2 to adaptively adjust their angle to adapt to the differences in the size of different equipment, comprehensively solving the risks of personnel slipping and bumping, and achieving safe passage.

[0019] The pedal 1 body is a rectangular plate, and the top of the pedal 1 body is provided with several anti-slip protrusions 11. The rectangular plate provides sufficient working area to ensure the stability of personnel standing and tools being placed. The anti-slip protrusions 11 on the surface significantly increase the friction coefficient of the shoe sole, especially in humid environments (such as the maintenance of dehumidifiers), effectively resisting slipping and preventing falls caused by the smooth surface of the trough.

[0020] The anti-slip protrusions 11 are provided with several horizontal protrusions 12 and vertical protrusions 13. The crisscrossing protrusions form a grid-like anti-slip pattern, achieving multi-directional anti-slip resistance. The horizontal protrusions 12 resist the forward and backward movement of the maintenance personnel's shoes (such as when stepping over), while the vertical protrusions 13 suppress lateral slippage (such as when turning), comprehensively improving the stability of the personnel's feet during dynamic operations.

[0021] The connecting hinge 6 includes a fixing plate 61. A cylinder 62 is provided at the bottom of the fixing plate 61 and near both sides of the fixing plate 61. The fixing plate 61 ensures that the hinge is rigidly connected to the pedal 1 body. The symmetrically distributed cylinder 62 structure provides precise positioning and support for the rotating shaft 63, ensuring the structural reliability of the hook 2 when it rotates and avoiding deformation failure caused by single-point force.

[0022] A rotating shaft 63 is installed inside the cylinder 62, and the overlapping hook 2 is fixedly installed on the rotating shaft 63. The design of the rotating shaft 63 allows the overlapping hook 2 to rotate around the shaft, realizing free adjustment at multiple angles. When there are differences in the thickness of the cylinder wall or the shape of the outer edge, the overlapping hook 2 can adaptively fit the attachment point, significantly improving the platform's compatibility with different models and equipment in different wear conditions, and simplifying the installation operation.

[0023] The lap hook 2 includes a straight rod 21, and a bent rod 22 is provided at the end of the straight rod 21. The straight rod 21 provides an extension length to cross the gap; the bent rod 22 at the end forms a barb structure, which generates a mechanical self-locking effect when it is attached to the outer edge of the cylinder wall, preventing the platform from accidentally disengaging when it is stepped on or vibrated, and ensuring the anchoring safety during long-term use.

[0024] The L-shaped plate 9 has several diagonal strips 91 on its surface. The texture of the diagonal strips 91 increases the surface roughness of the L-shaped plate 9, providing extra anti-slip protection when a person's foot accidentally touches the edge of the side plate; at the same time, it enhances the structural bending stiffness, suppresses the torsional deformation of the pedal 1 caused by concentrated load, and extends its service life.

[0025] A groove 5 is formed at the bend of the L-shaped plate 9 and at its center. This groove 5 creates an ergonomic grip handle for easy single-person handling and transport. The L-shaped plate 9 combines structural reinforcement with a carrying handle function, avoiding the added weight or interference caused by adding an extra handle, thus optimizing the platform's portability and storage efficiency. The hook 2 is attached to the outer edge 8 of the inner wall of the cylinder, using the existing structure of the cylinder (outer edge of the inner wall) as the load-bearing point. There is no need to modify the equipment body. The hook method disperses local stress, avoids indentation damage to the thin-walled cylinder, and provides a stable lever support foundation.

[0026] The interlocking interface 4 is fastened to the trough side 7 of the vibrating conveyor. The snap-fit ​​connection between the interlocking interface 4 and the trough side forms a quick-installation node, achieving instant fixation using the existing structure of the conveyor. The snap-fit ​​design restricts the platform's forward and backward and left and right displacements, forming a two-way constraint in conjunction with the interlocking hook 2, eliminating the risk of platform displacement during use.

[0027] When in use, the maintenance platform can be placed between the outer edge 8 of the inner wall of the cylindrical equipment and the sidewall 7 of the vibrating conveyor trough, as per [reference needed]. Figure 3 The platform is secured to the vibrating conveyor trough 7 via the interlocking interface 4, and the hook 2 is attached to the outer edge 8 of the inner wall of the cylinder, forming a passage platform between the vibrating conveyor and the cylinder. Operators can safely and quickly enter the cylinder equipment through the maintenance platform to carry out internal maintenance and cleaning operations, preventing bumps, slips, or trips when entering or leaving the cylinder equipment. After use, the operator can lift the platform through the slots 5 on both sides and remove it. The hook 2 is then flipped backward and hidden under the pedal 1 for storage, achieving quick storage of the maintenance platform.

[0028] Although the specific embodiments of the present utility model have been described above in conjunction with the accompanying drawings, this is not intended to limit the scope of protection of the present utility model. Those skilled in the art should understand that various modifications or variations that can be made by those skilled in the art without creative effort based on the technical solution of the present utility model are still within the scope of protection of the present utility model.
