Description

Technical Field

[0001] This utility model relates to the field of logistics and transportation technology, specifically to an anti-tipping component for tobacco transport cages. Background Technology

[0002] In small-scale material transfer scenarios within the tobacco industry, such as the cross-regional transportation and warehousing of tobacco leaf samples, cigarette cartons, and auxiliary materials, existing technologies generally employ wheeled cages as the core carrier container to improve the convenience of subsequent unloading, secondary transfer within the warehouse, and material supply to the production line. These cages are neatly stacked inside the cargo box for overall transportation. Tobacco materials have stringent requirements for cleanliness and integrity during the transfer process. These wheeled cages, with their enclosed structure and ease of cleaning, not only prevent tobacco from getting damp and contaminated with impurities, but also effectively reduce handling resistance during loading, unloading, and internal warehouse relocation through the roller structure. This significantly simplifies the multi-stage operation process from transport vehicles to warehouse shelves and then to the production workshop, and therefore has been widely used in tobacco logistics and cigarette production support.

[0003] However, in actual tobacco unloading operations, wheeled cages have certain drawbacks, impacting the safety and efficiency of tobacco transport. Commonly used cages for tobacco transport typically hold multiple layers of cigarette cartons or neatly stacked tobacco bales. While individual items are not particularly heavy, the overall center of gravity is concentrated, and the stability of the stack depends on its regularity. Routine operations such as dragging and tilting the cages during unloading easily disrupt their balance, exacerbating their instability and significantly increasing the risk of them tipping over.

[0004] Given the unique nature of tobacco materials, the consequences of tipping over tobacco cages are more severe: Firstly, cigarette cartons are prone to packaging damage and cigarette deformation due to impact, directly leading to a decline in product grade or even scrapping. Scattered tobacco bales may become unusable due to ground contamination, causing not only direct economic losses but also significantly reducing transport efficiency due to inventory, sorting, and rework. Secondly, tobacco warehousing and logistics involve densely populated areas, and tipped cages can cause collision injuries to personnel. Furthermore, if scattered tobacco materials come into contact with electrical equipment or open flames in the work area, there are certain safety hazards, contradicting the tobacco industry's strict safety production management regulations. In addition, some tobacco accessories, such as filter rods and packaging paper, are lightweight and fragile items. After tipping over, they are not only difficult to recover and organize but may also generate dust pollution due to breakage, affecting the cleanliness of the working environment. Utility Model Content

[0005] The purpose of this invention is to solve the problem that existing wheeled cages are prone to tipping over during unloading, causing harm to workers and goods, and to provide an anti-tipping component for tobacco transport cages.

[0006] To address the shortcomings of the aforementioned technical problems, the present invention adopts the following technical solution: an anti-tipping component for a tobacco transport cage, comprising a support unit and at least one pulling unit slidably connected to the support unit; The support unit includes a slide rail that can be installed on the top surface inside the cargo box. The slide rail includes an integrally formed straight section and a unloading section. The straight section extends along the depth of the cargo box, and the unloading section is located on the cargo door side of the cargo box. The unloading section is perpendicular to the straight section, and the unloading section and the straight section have a rounded transition at their ends. The pulling unit includes a slider that is slidably disposed in a slide rail. A support frame is fixedly connected to the bottom of the slider. A rotating shaft is provided on the support frame. A pulling rope with a C-shaped buckle fixedly connected to one end is wound around the rotating shaft. The working length of the pulling rope is fixed so that when the slider slides to the unloading section, the pulling rope can tighten the cage located on the unloading ground of the cargo box to prevent the cage from tilting to the side.

[0007] As a further optimization of the anti-tipping component for tobacco transport cage of this utility model: the bottom surface of the unloading section chute has a lower height relative to the bottom surface of the straight section chute, and the chute of the unloading section smoothly transitions to the chute of the straight section through an inclined section.

[0008] As a further optimization of the anti-tipping component for tobacco transport cage of this utility model: the rotating shaft is provided with two limiting discs and a reset torsion spring. The two limiting discs are coaxially fixed at both ends of the rotating shaft, and the reset torsion spring is sleeved between the support frame and the limiting discs.

[0009] As a further optimization of the anti-tipping component for tobacco transport cage of this utility model: multiple bolt seats are evenly distributed along the extension direction of the slide rail, and the slide rail is fixed to the reinforcing beam on the inner wall of the top of the cargo box by the fixing bolts.

[0010] As a further optimization of the anti-tipping component for tobacco transport cages of this utility model: the slide rail is made of high-strength aluminum alloy extrusion molding, and the slide rail groove is T-shaped; the slider is made of nylon reinforced with glass fiber injection molding into a T-shape, and the top of the slider is slidably connected in the slide groove.

[0011] As a further optimization of the anti-tipping component for tobacco transport cage of this utility model: baffles are provided at both ends of the slide rail, and the baffles are fixedly connected to the slide rail by closing bolts.

[0012] As a further optimization of the anti-tipping component for tobacco transport cage of this utility model: buffer pads made of elastic material are provided on both the front and rear end faces of the slider, and wear-resistant polytetrafluoroethylene bushings are embedded on the contact surface between the slider and the slide rail.

[0013] As a further optimization of the anti-tipping component for tobacco transport cage of this utility model: the outer side of the opening of the C-shaped buckle is provided with an external thread, and a screw sleeve is threaded on the external thread. After the screw sleeve is tightened, the opening of the C-shaped buckle can be locked, and the inner side of the screw sleeve is provided with an anti-slip rubber pad.

[0014] Compared with the prior art, the present invention has the following beneficial effects: This invention uses a preset anti-fall length for the pull rope to physically limit the cage during unloading, fundamentally preventing it from tipping over. A return torsion spring is used only before and after loading and unloading to automatically extend and retract the pull rope, making operation more convenient. The pull unit is connected to the cage. Specifically, when the cage is unloaded from the cargo box and placed on the unloading surface, the pull rope is tightened, limiting the distance between the cage and the top of the cargo box's inner wall, thereby reducing the probability of the cage tipping over and injuring workers or damaging goods when unloaded.

[0016] To better understand this utility model, the following embodiments further illustrate the content of this utility model, but the content of this utility model is not limited to the following embodiments.

[0017] like Figure 3 As shown, the support unit 1 serves as the mounting base for the fall arrestor, and includes a slide rail 102 and multiple bolt seats 103 fixedly connected to the slide rail 102. The slide rail 102 is made of high-strength aluminum alloy extrusion molding, with an overall rectangular cross-section and a T-shaped groove in the center. The slide rail 102 ensures smooth sliding of the slider 201 in the pulling unit 2 while meeting the load-bearing requirements.

[0018] The straight section 1021 of the slide rail 102 is arranged along the length of the cargo box 3, and its total length is adapted to the internal depth of the cargo box 3. In addition, the slide rail 102 also includes an unloading section 1022 integrally formed with the straight section 1021. The straight section 1021 occupies most of the length of the slide rail 102 and extends horizontally along the inner top wall of the cargo box 3, providing the main sliding stroke for the pulling unit 2. The unloading section 1022 and the straight section 1021 are connected by an arc transition at their ends, and the unloading section 1022 is flush with the side of the cargo door of the cargo box 3. This allows the pulling units 2 to be evenly distributed at the side of the cargo door of the cargo box 3, preventing the pulling units 2 from accumulating inside the straight section 1021 and affecting the unloading process of the cage 4. The T-shaped groove inside the unloading section 1022 slopes downward from the end of the straight section 1021. The T-slot of the unloading section 1022 allows the pulling unit 2, which slides to the unloading section 1022, to be temporarily stored in the unloading section 1022 under the action of gravity, or to not slide back to the straight section 1021 due to a change in position after being pushed to this area, thus achieving a temporary storage function. At the same time, it also makes it easier for operators to hold the pulling unit 2 and adjust its position, avoiding interference caused by the pulling unit 2 at the straight section 1021 at the cargo door. The lower setting of the T-slot of the unloading section 1022 also allows the pulling unit 2 to move downward, helping to keep the pulling unit 2 connected to the cage 4 while unloading the cage 4 into the cargo box 3.

[0019] Bolt seats 103 are L-shaped, stamped from steel plates. Bolt holes are provided on the horizontal plate, and the vertical plate is fixedly connected to the side of the slide rail 102. Bolt seats 103 are evenly distributed along the extension direction of the slide rail 102. Bolt holes allow fixing bolts to pass through, securing the bolt seats 103 to the inner top wall of the cargo box 3. High-strength expansion bolts are used for fixing, allowing the slide rail 102 to be detachably fixed to the reinforcing beam on the inner top wall of the cargo box 3 via the bolt seats 103, ensuring the slide rail 102 is firmly fixed without any loosening.

[0020] Both ends of the slide rail 102 are equipped with retaining plates 101, which are fixed to both ends of the slide rail 102 by closing bolts. Each retaining plate 101 has two threaded holes, which are threadedly connected to the blind threaded holes at both ends of the slide rail 102 by closing bolts, thereby fixing the retaining plate 101 and sealing both ends of the slide rail 102. The retaining plates 101 effectively prevent the slider 201 from detaching from both ends of the slide rail 102 and facilitate disassembly and maintenance.

[0021] like Figure 4As shown, the pulling unit 2 slides in conjunction with the support unit 1, and each pulling unit 2 independently corresponds to a cage 4. The pulling unit 2 includes a slider 201 that slides in conjunction with the slide rail 102 and a wear-resistant bushing. The slider 201 is injection molded into a T-shape using nylon reinforced with glass fiber. Its top is embedded in a T-shaped groove opened in the center of the slide rail 102, and a polytetrafluoroethylene wear-resistant bushing is inlaid on the contact surface with the slide rail 102 to extend its service life. The bottom of the slider 201 is provided with a cylindrical connecting post with external threads on its outer surface for fixed connection with the support frame 202. Low-friction buffer pads can be provided on the front and rear end faces of the slider 201. The buffer pads are made of rubber or engineering plastic. When multiple pulling units 2 are densely arranged on the slide rail 102 or in contact with each other, the buffer pads can effectively absorb collision energy, prevent jamming or damage caused by rigid impact, and ensure that each pulling unit 2 can still slide independently.

[0022] The support frame 202 is a welded steel plate structure, consisting of an upper connecting plate, a lower support plate, and two side uprights. The upper connecting plate has a threaded hole in its center that matches the connecting column, allowing the lower support plate to be connected and fixed to the slider 201 via a threaded connection. The lower support plate and the two side uprights form a U-shaped receiving space, and symmetrical bearing mounting holes are provided on the two side uprights for installing the support bearings of the connecting shaft 203.

[0023] One end of a pull rope 206 is mounted on the rotating shaft 203, and the other end of the pull rope 206 is connected to a C-shaped buckle 207. A threaded sleeve 208 is threaded into the opening of the C-shaped buckle 207. The length of the pull rope 206 is fixed. Specifically, the effective working length of the pull rope 206 is preset so that when the slider 201 is located within the unloading section 1022 and the cage 4 is stably placed on the unloading ground, the pull rope 206 is just taut. One end of the pull rope 206 is fixed to the rope groove in the middle of the rotating shaft 203 by a wire rope clamp. The width of the rope groove matches the diameter of the pull rope 206, and the depth is 1.2 times the diameter of the pull rope 206. The other end is fixedly connected to the C-shaped buckle 207 by a crimp connector. The outer side of the opening of the C-shaped buckle 207 has external threads, and the sleeve 208 is a stainless steel nut with an anti-slip rubber pad on the inner side. After tightening, the opening of the C-shaped buckle 207 can be locked to prevent it from detaching from the cage 4.

[0024] The rotating shaft 203 is equipped with two limiting discs 205 and two return torsion springs 204. The two limiting discs 205 are coaxially fixed at both ends of the rotating shaft 203, which can limit the winding range of the pull rope 206. The return torsion spring 204 is made of spring steel and is sleeved on the rotating shaft 203. One end is embedded in the slot of the support frame 202, and the other end is embedded in the positioning hole of the limiting disc 205. In the initial state, the return torsion spring 204 is in a pre-tensioned state, providing a return torque to ensure that the pull rope 206 can automatically wind onto the rotating shaft 203 when no force is applied.

[0025] Support unit 1 is detachably connected to the reinforcing beam on the inner wall of the top of cargo box 3 via fixing bolts, ensuring that the slide rail 102 is arranged horizontally. The slider 201 of the pulling unit 2 is embedded in the slide rail 102 to achieve sliding engagement. Each slide rail 102 can accommodate 4 to 8 pulling units 2, with the specific number adapted according to the width of cargo box 3 and the size of cage box 4. The C-shaped buckle 207 of the pulling unit 2 is used to connect with the lifting ring or reinforcing rib on the top of cage box 4. Through the length limitation of the pulling rope 206 and the reset action of the return torsion spring 204, the cage box 4 is protected against tipping.

[0026] In practical use, first, select the appropriate length of the slide rail 102 according to the size of the cargo box 3, namely the straight section 1021 and the unloading section 1022. Place the slide rail 102 at the position of the reinforcing beam on the inner wall of the top of the cargo box 3, and adjust the levelness of the slide rail 102 to ensure that the straight section 1021 is level and the unloading section 1022 is flush with the side of the cargo door of the cargo box 3. The unloading section 1022 can bear all the pulling units 2 on the slide rail 102 to maintain the effect of unloading by the operator. Next, evenly arrange the bolt seats 103 along the length of the slide rail 102, and fasten the bolt seats 103 to the reinforcing beam on the top of the cargo box 3 with fixing bolts to ensure that each bolt seat 103 is evenly stressed and has no loosening. Next, insert the slider 201 of the pulling unit 2 into the slide rail 102, push the pulling unit 2 to slide along the slide rail 102, and check whether the sliding is smooth. At the same time, pull the pulling rope 206 to check whether the reset torsion spring 204 resets flexibly and whether the pulling rope 206 is neatly wound without misalignment or entanglement. Then, fix the baffle 101 to both ends of the slide rail 102 with the closing bolts, check the installation of the baffle 101 to ensure that the slider 201 cannot come out from both ends of the slide rail 102.

[0027] like Figure 2 As shown, cages 4 are then loaded into cargo boxes 3 one by one. Depending on the placement of cages 4 within cargo box 3, the corresponding pulling unit 2 is slid to position it directly above or slightly above the top of cage 4. Next, the C-shaped buckle 207 of the pulling unit 2 is pulled, simultaneously hooking the opening of the C-shaped buckle 207 onto the lifting ring or reinforcing rib at the top of cage 4. After ensuring a secure connection, the threaded sleeve 208 at the opening of the C-shaped buckle 207 is tightened. The anti-slip rubber pad inside the threaded sleeve 208 locks the opening in place, preventing it from falling off during transport. Finally, the sliding, pulling, hooking, and tightening operations are repeated to complete the connection of all cages 4 to the pulling unit 2, ensuring that each cage 4 is connected to at least one pulling unit 2. Larger cages 4 can be connected to two pulling units 2 and arranged symmetrically.

[0028] During unloading and separation, the cargo door 3 is opened first after the truck arrives at its destination. Then, the sliding block 201 is pulled into the unloading section 1022, preventing multiple sliding blocks 201 from piling up at the end of the straight section 1021 facing the cargo door 3. Figure 1 and Figure 2As shown, during unloading, the slider 201 is pushed from the straight section 1021 to the unloading section 1022, and the cage 4 is pulled out. Since the effective working length of the pull rope 206 is fixed, when the cage 4 is placed on the unloading ground, the pull rope 206 is immediately tightened, thereby limiting the overturning range of the cage 4 and preventing tipping. Before the pull rope 206 is tightened, the weight of the cage 4 will pull the pull rope 206, causing the pull rope 206 to drive the rotating shaft 203 to overcome the torque of the return torsion spring 204, and the pull rope 206 wrapped on the rotating shaft 203 will be released. Then the cage 4 will be unloaded from the cargo box 3 and placed on the unloading ground. After the cage 4 is unloaded and stably placed on the unloading ground of the cargo box 3, the screw sleeve 208 on the corresponding C-shaped buckle 207 can be loosened to open the opening and remove the C-shaped buckle 207 from the lifting ring or reinforcing rib on the top of the cage 4. After the C-shaped buckle 207 separates from the cage 4, the pull rope 206 will automatically wind up onto the rotating shaft 203 under the reset torque of the reset torsion spring 204. The limiting plate 205 restricts the winding range of the pull rope 206 to prevent misalignment. If further unloading is required, repeat the above loosening, removing, and pulling operations to separate other cages 4 from the pull unit 2 in sequence. Finally, after all cages 4 have been unloaded, slide all pull units 2 to any position on the straight section 1021 of the slide rail 102 for easy use next time.

[0029] The specific model parameters of the reset torsion spring 204 in this embodiment should be understood as prior art.

[0030] The specific embodiments of this utility model have been described above. It should be understood that this utility model is not limited to the specific embodiments described above, and those skilled in the art can make various modifications or variations within the scope of the claims, which do not affect the substantive content of this utility model.
