Description

Technical Field

[0001] This utility model relates to the technical field of anti-collision equipment for baggage conveyors, specifically an anti-collision device for baggage conveyors. Background Technology

[0002] Baggage conveyors are mechanical devices used in airports, train stations, and other places to automatically transport baggage. They consist of conveyor belts, drive units, and supports, and are used to efficiently sort and transport passenger baggage. Anti-collision devices are safety devices used to protect luggage, packages, and other items from collisions during the baggage conveyor's transport process. They prevent damage to luggage, packages, and other items when they slide down and collide with equipment components, and also prevent abnormal impacts from causing structural damage or malfunctions to the conveyor.

[0003] For example, a Chinese patent document discloses an airport luggage anti-collision device (publication number: CN213594550 U). Although this patent reduces labor costs by adopting mechanized operations, the principle of this device is very simple, the materials used are also very common, the cost is low, the cost-effectiveness is high, the subsequent maintenance cost is low, and the effect is significant. It is conducive to improving the service level of airports and reducing economic disputes.

[0004] However, this method relies solely on sponge tubes for cushioning. Its energy absorption method is simple and the cushioning threshold is fixed. When faced with heavy luggage or violent impacts from high-speed drops, the sponge tubes are prone to saturation due to deformation and lose their cushioning effect, making the luggage still susceptible to impact damage. The protection is significantly limited. Utility Model Content

[0005] The purpose of this utility model is to provide an anti-collision device for a baggage conveyor in order to solve the above problems.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an anti-collision device for a luggage conveyor, comprising: a base, an inverted U-shaped frame vertically slidably connected above the base, an L-shaped back panel fixedly connected to one end of the lower part of the inverted U-shaped frame, a cylinder fixedly connected to the other end of the base, a support rod fixedly connected to the upper front end of the L-shaped back panel, a limit block engaging at the head end of the support rod, a buffer mechanism provided at one end of the support rod, and an airbag mechanism fixedly connected to the center of the front side of the L-shaped back panel.

[0007] As a further embodiment of this utility model: the buffer mechanism includes a threaded short rod, a through hole, and a limiting lock cover. The threaded short rod is movably inserted into one end of a support rod, the through hole is opened in the upper middle part of the threaded short rod, the support rod is adapted to the through hole, and the limiting lock cover is threadedly connected to the outside of the threaded short rod; an inner rod and a limiting bottom block, the inner rod is fixedly connected to the bottom of the threaded short rod, and the limiting bottom block is fixedly connected to the bottom of the inner rod; a ball and a roller, the ball is movably embedded in the middle of the bottom of the limiting bottom block, and the roller is movably inserted into the outside of the inner rod.

[0008] As a further embodiment of this utility model: the airbag mechanism includes an airbag, an elastic honeycomb plate and air holes. The airbag is fixedly connected to the center of the front of the L-shaped back panel, the elastic honeycomb plate is fixedly connected to one end inside the airbag, and the number of air holes is provided in multiple sets, symmetrically opened on both sides of the airbag.

[0009] As a further improvement of this utility model: the number of cylinders is provided in two sets, and the movable end of the cylinder is fixedly connected to the bottom of the L-shaped back panel.

[0010] As a further improvement of this utility model: multiple sets of the support rod, the limiting block and the buffer mechanism are provided, and multiple sets of the support rod are symmetrically arranged on the front of the L-shaped back panel.

[0012] As a further embodiment of this utility model: the number of elastic honeycomb panels is provided in multiple groups, symmetrically located inside the airbag, the airbag is made of thermoplastic polyurethane material, and the elastic honeycomb panels are made of polyurethane foam material.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This invention relates to a device installed at a point on a baggage conveyor where slippage is likely. The vertical position of the L-shaped back panel can be adjusted via a cylinder according to the height of the conveyor or baggage, aligning it with the impact point of the slipping baggage. The inverted U-shaped frame and base connection ensure stable adjustment. Its advantages are significant: Firstly, it reduces scratches and facilitates maintenance. When baggage slips, it first contacts multiple symmetrical buffer mechanisms, transforming sliding friction into rolling friction upon impact with the rollers, reducing scratches. The axial displacement of the rollers is restricted to prevent detachment, and the bottom ball bearings ensure smooth movement. This initially dissipates impact energy, and the buffer mechanism is easy to disassemble, allowing for quick roller replacement. Secondly, it achieves dual buffering and graded protection. After impact, the buffer mechanism impacts the airbag mechanism, causing the airbag to be compressed and expelled. The elastic honeycomb plate disperses the impact force and maintains its shape. After the external force disappears, the airbag rebounds and retracts air to reset. The buffer mechanism's "rolling friction + axial buffering" is suitable for light baggage or minor impacts, while the airbag mechanism's "gas expulsion + honeycomb deformation" handles heavy baggage or severe impacts, forming a graded protection system. Furthermore, the cylinder height adjustment and multiple symmetrical buffer units can adapt to baggage of different sizes and weights, effectively preventing collisions and reducing the risk of conveyor breakage.

Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance. In the description of this utility model, it should be noted that unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "setting" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of 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. The embodiments of this utility model will be described below based on its overall structure.

[0022] Reference Figures 1 to 4 In this embodiment of the utility model, an anti-collision device for a baggage conveyor includes: a base 1, an inverted U-shaped frame 2 vertically slidably connected above the base 1, the base 1 serving as the basic fixing component of the device, providing stable support for the overall structure, and also serving as the sliding track of the inverted U-shaped frame 2 to ensure stability during height adjustment, and an L-shaped back panel 3 fixedly connected to one end of the lower part of the inverted U-shaped frame 2, serving as the installation base for supporting multiple mechanisms and transmitting the impact force to each protective component.

[0023] A cylinder 4 is fixedly connected to the other end of the base 1 as a power adjustment component. A support rod 5 is fixedly connected to the upper front end of the L-shaped back panel 3 as a support bracket. The head end of the support rod 5 is engaged with a limit block 6, which is adapted to the support rod 5 as a limiting component. A buffer mechanism 7 is provided at one end of the support rod 5. An airbag mechanism 8 is fixedly connected to the middle of the front of the L-shaped back panel 3. There are two sets of cylinders 4. The movable end of the cylinder 4 is fixedly connected to the bottom of the L-shaped back panel 3. There are multiple sets of support rods 5, limit blocks 6 and buffer mechanisms 7. Multiple sets of support rods 5 are symmetrically arranged on the front of the L-shaped back panel 3.

[0024] Reference Figure 1 and Figure 3 The buffer mechanism 7 includes a threaded short rod 71, a through hole 72 and a limiting lock cover 73. The threaded short rod 71 is movably inserted into one end of the support rod 5. The through hole 72 is opened in the middle of the upper part of the threaded short rod 71. The support rod 5 is adapted to the through hole 72. The limiting lock cover 73 is threadedly connected to the outside of the threaded short rod 71.

[0025] The inner rod 74 and the limiting bottom block 75 are fixedly connected to the bottom of the threaded short rod 71, and the limiting bottom block 75 is fixedly connected to the bottom of the inner rod 74; the ball 76 and the roller 77 are movably embedded in the middle of the bottom of the limiting bottom block 75, and the roller 77 is movably inserted into the outside of the inner rod 74.

[0026] Both the limit lock cover 73 and the limit base block 75 are movably connected to the roller 77, which is made of silicone material. When luggage slides off the conveyor belt and approaches the device, it first contacts multiple symmetrically arranged buffer mechanisms 7. The luggage impacts the roller 77, and the roller rotates along the inner rod 74, converting sliding friction into rolling friction and reducing scratches on the luggage surface. When the impact force pushes, it is guided by the through hole 72 and the support rod 5, causing the threaded short rod 71 to move axially along the support rod 5. The limit lock cover 73 and the limit base block 75 restrict the axial displacement of the roller 77 to prevent it from falling off. At the same time, the ball bearings 76 at the bottom of the limit base block 75 move with the edge of the luggage conveyor, making its movement smoother. This can initially dissipate the impact energy. Furthermore, by removing the limit clip 6, the entire buffer mechanism 7 can be disassembled. Then, by loosening the limit lock cover 73, the roller 77 can be removed and replaced. The operation is very convenient and quick.

[0027] Reference Figure 1 and Figure 4 The airbag mechanism 8 includes an airbag 81, an elastic honeycomb plate 82, and air holes 83. The airbag 81 is fixedly connected to the center of the front of the L-shaped back panel 3. The elastic honeycomb plate 82 is fixedly connected to one end of the airbag 81. The air holes 83 are provided in multiple sets and are symmetrically opened on both sides of the airbag 81.

[0028] Multiple sets of elastic honeycomb panels 82 are symmetrically arranged inside the airbag 81. The airbag 81 is made of thermoplastic polyurethane, and the elastic honeycomb panels 82 are made of polyurethane foam. When the buffer mechanism 7 is impacted, it directly impacts the airbag mechanism 8. The thermoplastic polyurethane material of the airbag 81 is compressed and deformed. Due to the increased pressure, the internal gas is quickly discharged from the symmetrically opened air holes 83 on both sides. The gas flow further absorbs the impact energy. The multiple sets of elastic honeycomb panels 82 inside the airbag 81 are simultaneously compressed. Their closed-cell structure disperses the impact force through its own deformation, while also helping to maintain stability. The airbag's shape stability prevents excessive collapse. After the conveyor belt takes the luggage away and the external force disappears, the airbag 81 expands due to the high resilience of thermoplastic polyurethane, creating a negative pressure inside. It then draws in external air through the air holes 83, restoring its initial inflation state. The polyurethane foam material of the elastic honeycomb panel 82, due to its own elasticity, pushes the inner wall of the airbag to rebound synchronously, accelerating the air intake process. At the same time, the buffer mechanism 7, without the action of external force, resets itself through the support force of the support rod 5. The cooperation between the ball bearing 76 and the inner rod 74 ensures that all components return to their initial positions, waiting for the next luggage impact.

[0029] The working principle of this utility model is as follows: When in use, the device is installed at the easy-to-slip position of the baggage conveyor. The vertical position of the L-shaped back panel 3 can be adjusted by the cylinder 4 according to the height of the baggage conveyor or the average height of the baggage, so as to ensure that it is aligned with the impact position of the slipping baggage and improve the protection. The connection between the inverted U-shaped frame 2 and the base 1 is to maintain the stability during adjustment.

[0030] When luggage slides off the conveyor belt and approaches the device, it first contacts multiple symmetrically arranged buffer mechanisms 7. The luggage impacts the roller 77, which rotates along the inner rod 74, converting sliding friction into rolling friction and reducing scratches on the luggage surface. When the impact force pushes, it is guided by the through hole 72 and the support rod 5, causing the threaded short rod 71 to move axially along the support rod 5. The limit lock cover 73 and the limit bottom block 75 restrict the axial displacement of the roller 77 to prevent it from falling off. At the same time, the ball bearings 76 at the bottom of the limit bottom block 75 move with the edge of the luggage conveyor, making its movement smoother. This can initially consume the impact energy. Furthermore, by removing the limit block 6, the entire buffer mechanism 7 can be disassembled. Then, by loosening the limit lock cover 73, the roller 77 can be removed for replacement. The operation is very convenient and quick.

[0031] After the buffer mechanism 7 is impacted, it directly impacts the airbag mechanism 8. The thermoplastic polyurethane material of the airbag 81 is compressed and deformed. Due to the increased pressure, the internal gas is rapidly discharged from the symmetrically opened air holes 83 on both sides, using the gas flow to further absorb the impact energy. The multiple sets of elastic honeycomb plates 82 inside the airbag 81 are simultaneously compressed. Their closed-cell structure disperses the impact force through its own deformation, while also helping to maintain the shape stability of the airbag and prevent excessive collapse. When the conveyor belt takes away the luggage and the external force disappears, the airbag 81 expands due to the high resilience of the thermoplastic polyurethane. A negative pressure is created, and external air is re-drawn in through the air hole 83 to restore the initial inflation state. The polyurethane foam material of the elastic honeycomb panel 82 returns to its original elasticity, pushing the inner wall of the airbag to rebound synchronously, accelerating the air intake process. At the same time, the silicone roller 77 and the threaded short rod 71 return to their original positions under the support of the support rod 5 without the action of external force. The cooperation between the ball bearing 76 and the inner rod 74 ensures that each component returns to its initial position, waiting for the next luggage impact. In this way, the buffer mechanism 7 achieves the first level of force relief through "rolling friction + axial buffering", which is suitable for light luggage or slight impacts.

[0032] The airbag mechanism 8 achieves a second level of strong buffering through "gas exhaust and suction + honeycomb deformation" to cope with heavy luggage or severe impacts. The combination of the two forms a graded protection system. At the same time, the height adjustment function of the cylinder 4 and multiple symmetrically distributed buffer units can adapt to luggage of different sizes and weights, ultimately achieving efficient anti-collision protection for slipping luggage and reducing the risk of damage during transportation.

[0033] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
