Description

Technical Field

[0001] This utility model relates to the field of collision protection technology, and in particular to a collision protection structure for cargo handling. Background Technology

[0002] Collision protection during cargo handling is a crucial aspect of logistics, transportation, and warehousing operations, playing a vital role in ensuring the safety of goods and minimizing losses during transport. In various industrial production and commodity circulation scenarios, the frequent handling of goods continuously increases the risk of collisions.

[0003] Traditional collision protection structures typically employ simple, fixed guardrails with non-adjustable heights, making them extremely unsuitable for handling goods of varying heights. When moving taller goods, insufficient guardrail height fails to provide effective protection, easily leading to tilting or falling during transport due to vehicle vibrations or steering, resulting in collision damage. Conversely, for shorter goods, excessively high guardrails waste space and increase handling inconvenience. Furthermore, traditional structures lack effective monitoring and warning devices, failing to promptly notify operators of impending collisions, making it difficult for them to take timely measures to prevent accidents and further increasing the likelihood of cargo damage.

[0004] To address this issue, this invention proposes a collision-resistant protection structure for cargo handling. Through an innovative design, it features a side rail assembly with adjustable height, utilizing multi-stage telescopic rods and a convenient locking structure to tightly adapt to cargo of varying heights, effectively enhancing cargo protection. Simultaneously, a monitoring and warning system with an adjustable-angle infrared alarm and warning lights is added, enabling real-time monitoring and hazard warning of the handling environment. This system quickly alerts operators when potential collision risks occur, significantly improving the safety and reliability of cargo handling and reducing the probability of cargo damage. Utility Model Content

[0005] The technical problem to be solved: poor adaptability to cargo of different heights and the lack of effective monitoring and warning devices in traditional structures.

[0006] To achieve the above objectives, this utility model proposes a cargo handling anti-collision protection structure, including a shelf tray. The top of the shelf tray has a slot and a side rail assembly. The side rail assembly includes a side rail frame and a plurality of locking rods are fixedly connected to the bottom of the side rail frame. The side rail frame is connected to the shelf tray by locking the locking rods inside the side rail frame.

[0007] The side railing is equipped with a multi-stage telescopic rod in the middle. Each extension rod of the multi-stage telescopic rod has a crossbar at its top. The upper middle part of the side railing and the middle part of the multiple crossbars are provided with opposing moving slots. Each of the multiple moving slots is slidably connected with a locking rod II. Each of the multiple locking rod IIs is fixedly connected with a pressing plate in the middle. Each of the multiple locking rod IIs is fitted with a spring on its outer side. The upper and lower sides of the opposite sides of each extension rod of the multi-stage telescopic rod on both sides of the side railing are provided with locking slots II.

[0008] In one example, latches are installed on both sides of the top of the side rail and on both sides of the multiple crossbars.

[0009] In one example, an infrared alarm and a warning light are fixedly connected to the middle of the top crossbar. The infrared alarm has a hinge in the middle, and the angle of the infrared alarm can be adjusted by the hinge.

[0010] In one example, spring grooves extend from the center of each of the multiple moving slots, and the extrusion plate and spring are disposed inside adjacent spring grooves.

[0011] In one example, pull rings are fixedly connected to the opposite ends of the two clamps that are set opposite each other on the upper middle part of the side rail frame and the middle part of the multiple crossbars.

[0012] In one example, the card slots are provided on all four sides of the shelf tray.

[0013] In one example, the end of the second lever away from the pull ring engages with the adjacent second slot.

[0014] The cargo handling anti-collision protection structure proposed in this utility model has the following beneficial effects:

[0015] 1. In this utility model, the adjustable height side rail component design achieves precise adaptation and effective protection for goods of different heights. The multi-stage telescopic rod and crossbar structure in the side rail component, together with the unique locking rod, locking groove and spring device, can easily adjust the height to fit the actual size of the goods. During the handling process, whether it is a tall fragile item or a low small item, it can be properly protected, avoiding displacement, falling or collision of goods when the vehicle shakes or bumps due to unsuitable side rail height, greatly reducing the risk of damage to goods and ensuring handling safety and the integrity of goods.

[0016] 2. This utility model achieves comprehensive intelligent monitoring and efficient warning of the handling environment through the coordinated operation of the infrared alarm and warning light, and the adjustable sensing range. The angle of the infrared alarm can be adjusted using a hinge to expand or shrink the sensing range as needed, accurately capturing potential collision risks in complex and diverse handling environments. Once an alarm is triggered abnormally, the warning light immediately illuminates simultaneously, providing multi-dimensional visual and auditory alerts to surrounding personnel in noisy workshops or situations where personnel are distracted, effectively preventing accidents and improving the safety and reliability of goods handling.

Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more solutions or examples.

[0034] like Figures 1-9As shown, an embodiment of this utility model proposes a cargo handling anti-collision protection structure, which includes a rack tray 1, similar to a traditional forklift rack, which can be transported by a forklift. The top of the rack tray 1 is provided with a slot 2, and the top of the rack tray 1 is provided with a side rail assembly, which includes a side rail frame 3. The bottom of the side rail frame 3 is fixedly connected with multiple levers 4. The side rail frame 3 is connected to the rack tray 1 by locking the levers 4 inside the side rail frame 3. The slots 2 are provided around the rack tray 1, so the side rail frame 3 can be randomly installed on any side of the rack tray 1, or multiple sides can be installed simultaneously.

[0035] A multi-stage telescopic bar 5 is installed in the middle of the side rail frame 3. A crossbar 6 is installed at the top of each extension bar of the multi-stage telescopic bar 5. Oppositely arranged moving grooves 7 are provided in the upper middle of the side rail frame 3 and in the middle of the multiple crossbars 6. Spring grooves 8 extend from the middle of each of the multiple moving grooves 7. Locking rods 9 are slidably connected inside each of the multiple moving grooves 7. A pressing plate 10 is fixedly connected to the middle of each of the multiple locking rods 9. Spring elements 11 are sleeved on the outer sides of each of the multiple locking rods 9. The opposite ends of the locking rods 9, which are oppositely arranged in the upper middle of the side rail frame 3 and in the middle of the multiple crossbars 6... Each side rail is fixedly connected with a pull ring 12. The upper and lower sides of the various extension rods of the multi-stage telescopic rods 5 on both sides of the side rail frame 3 are provided with slots 2 13. When the side rail assembly is installed at the top of the shelf tray 1, the height of the side rail assembly can change according to the height of the goods. First, pull two adjacent pull rings 12 simultaneously inwards. The pull rings 12 drive the slots 2 9 to move simultaneously to the opposite side. Then, the slots 2 9 drive the pressing plate 10 to press the spring 11. As the slots 2 9 move inwards, the outer ends of the adjacent slots 2 9 separate from the lower slots 2 13, thus releasing the lock. The second lever 9 restricts the extension and retraction of the multi-stage telescopic rod 5. At this point, lifting the horizontal bar 6 on the upper side of the pulled ring 12 will extend the rod. During this lifting process, the horizontal bar 6 will cause the extension rod of the first stage of the multi-stage telescopic rod 5 connected to it to extend upwards. Simultaneously, the pulled ring 12 is released. After the pull ring 12 is released, the compressive force of the spring 11 is released, and the spring 11 rebounds. The springs 11 on both sides push the compression plates 10 on both sides, causing the connecting lever 9 connected to them to move to the opposite side until the opposite ends of the connecting levers 9 on both sides compress the multi-stage telescopic rod 5. On the outer wall, after the extension rod on the multi-stage telescopic rod 5 extends upward to a certain height, the slot 13 on the lower side of the extension rod coincides with the opposite end of the locking rod 9. Under the push of the spring 11's rebound force, the outer end of the spring 11 engages with the slot 13, thereby fixing the height of the extension rod of the multi-stage telescopic rod 5. When it is necessary to lower it, simply pull the pull ring 12 to pull the locking rods 9 on both sides inward again, releasing the restriction of the opposite ends of the two adjacent locking rods 9 on the slot 13. The extended part of the multi-stage telescopic rod 5 then falls down under the action of gravity and then returns to its original position.

[0036] Locking buckles 14 are installed on both sides of the top of the side rail frame 3 and on both sides of the multiple crossbars 6. By interlocking the locking buckles 14 on adjacent side rail frames 3 or crossbars 6, the connection between multiple sets of side rail components can be made more secure, thereby preventing the side rail components from shaking during use, such as during the handling of goods, due to vehicle shaking or bumps during driving. This stable connection can ensure the overall stability of the anti-collision protection structure for handling goods and better perform its function of protecting goods.

[0037] Infrared alarm devices 15 and warning lights 17 are fixedly connected to the middle of the top crossbar 6 of the side rail assembly. A hinge 16 is provided in the middle of the infrared alarm device 15, and the angle of the infrared alarm device 15 can be adjusted by tightening the hinge 16. Figure 10 As shown, when the angle of the infrared alarm 15 continuously decreases, its infrared sensing range continuously shrinks; when the angle of the infrared alarm 15 continuously increases, its infrared sensing range continuously expands. Adjusting the angle of the infrared alarm 15 via the hinge 16 changes the infrared sensing range, adapting to different scenarios and needs. For example, in situations with limited space and requiring focused monitoring of nearby areas, the angle of the infrared alarm 15 can be adjusted downwards to shrink the sensing range and concentrate monitoring of specific nearby areas; conversely, when expanding the monitoring range, such as for perimeter security in open areas, the angle can be raised to expand the sensing range and achieve monitoring of a wider area.

[0038] Together with the warning light 17, it is installed in the middle of the top horizontal bar 6 of the side rail assembly. When the infrared alarm 15 senses an abnormal situation and triggers the alarm, the warning light 17 will light up simultaneously, using visual signals to assist the sound alarm. In noisy environments or when people's attention is distracted, it will visually attract people's attention, enhance the warning effect, and promptly remind people around of potential dangers.
