Description

Technical Field

[0001] This invention belongs to the field of safety protection technology, and in particular relates to a self-adjusting safety protection component and the safety guardrail composed thereof. Background Technology

[0002] In production workshops, logistics transfer warehouses, and other places, delivery equipment is often used to transport goods, such as forklifts. During the use of forklifts, it is easy for them to collide with corners, shelves or other equipment. In order to avoid damage to the goods themselves, delivery equipment and the objects being hit, it is necessary to add guardrails in relevant locations.

[0003] Traditional crash barriers use rigid connections between the base and the posts, as well as between the posts and the fence. Therefore, in the event of a collision, the connecting parts and the barrier will be directly damaged. Moreover, due to the structural strength of the barrier itself, it can also damage the delivery equipment and, in severe cases, cause damage to the goods.

[0004] The applicant uses imported European polymers as the base material and incorporates more than a dozen internationally standardized environmentally friendly materials such as high-toughness polymers, antioxidants, ultraviolet absorbers, light stabilizers, antistatic agents, nucleating agents, and scratch-resistant agents to polymerize and modify them, forming the unique LB-FS2019 polymer material.

[0005] The LB-FS2019 polymer material features a stable and robust integration of polymer chains, resulting in products with exceptional rigidity and flexibility, and excellent mechanical strength. It effectively distributes localized stress to other parts of the product, achieving stress relief and buffering, preventing damage and cracking. This robust molecular structure also allows the product to quickly recover its shape after being subjected to stress, maintaining its original form. Products made of LB-FS2019 polymer material maintain excellent impact resistance and flexibility between -40°C and 80°C. After undergoing 24-hour low-temperature and 24-hour high-temperature cyclic high-temperature tests by authoritative institutions, followed by a 2 / 3 compression deformation test, no embrittlement or cracking was observed. Products made of LB-FS2019 polymer material exhibit UV resistance according to Toyota's TSF7365G 5.2.5 Jan. 2017 standard, undergoing an extreme test in a xenon chamber for over 1500 hours (equivalent to 3 years outdoors) without embrittlement, discoloration, deformation, or cracking. LB-FS2019 polymer material, with an ignition point of 290°C, does not release toxic or harmful gases after combustion in ultra-high temperature combustion tests. The material is insulating and non-conductive, corrosion-resistant, acid and alkali-resistant, and wear-resistant, making the product suitable for use in various indoor and outdoor conditions.

[0006] Therefore, the inventors have discovered that by using the above-mentioned material as the main protective element, its high elasticity can effectively improve the protection level in workshops and other similar settings. Summary of the Invention

[0007] The purpose of this invention is to provide a self-adjusting safety protection component and a safety guardrail thereof. This self-adjusting safety protection component can autonomously change the buffering and energy absorption capacity of the crossbeam according to the change of pressure, thus providing good protection against collision forces of different magnitudes. At the same time, the safety guardrail constructed using this self-adjusting safety protection component can be adjusted in shape as needed, making it widely applicable.

[0008] To achieve the above objectives, the present invention provides the following technical solution: a self-adjustable safety protection component and a safety guardrail thereof. The self-adjustable safety protection component includes a connecting frame and a crossbeam detachably connected to the connecting frame. A first buffer core is fixed inside the connecting frame with screws. A connecting buffer body is sleeved outside the first buffer core. The crossbeam is inserted and installed between two connecting bodies. A self-adjusting component is provided inside the connecting body. The self-adjusting component includes an abutting arc plate that slides inside the connecting buffer body and a pressure sensor module installed inside the crossbeam.

[0009] In a preferred embodiment of the present invention, the connecting buffer body has a T-shaped structure, and an insertion interface is provided on one side of the connecting buffer body. The two ends of the crossbeam are trapezoidal and are inserted into the insertion interface. A waist-shaped travel groove is provided on the side of the insertion interface, and a screw is inserted into the travel groove to lock the crossbeam.

[0010] In a preferred embodiment of the present invention, the self-adjusting component further includes a connecting seat fixed inside the contact arc plate, a moving rod fixed inside the connecting seat, the end of the moving rod away from the contact arc plate extending along one end of the connecting buffer body, a cylinder fixedly connected to the extended end of the moving rod, the cylinder being electrically connected to the pressure sensor module, and the connecting buffer body having an oblong groove for sliding the contact arc plate.

[0011] In a preferred embodiment of the present invention, a spring is sleeved on the outside of the moving rod, one end of the spring is fixed to the inner wall of the connecting buffer body, and the other end is fixed to the connecting seat.

[0012] In a preferred embodiment of the present invention, connecting ring blocks are snapped onto both ends of the first buffer core, and the connecting ring blocks are fixedly connected to the connecting frame with screws.

[0013] In a preferred embodiment of the present invention, the pressure sensor is provided with a support frame on the outside, the pressure sensor is snapped into the inside of the support frame, a second buffer core is inserted into the end of the support frame away from the pressure sensor module, a plurality of second buffer cores are provided, and all the plurality of second buffer cores are inserted into the inside of the support frame, and the pressure sensor module is located in the middle of the crossbeam.

[0014] In a preferred embodiment of the present invention, a third buffer core is also fixed inside the crossbeam. Two third buffer cores are provided near both ends of the crossbeam. A cooperative sensing plate is sleeved and fixed between the two third buffer cores. An abutment block is fixed on the cooperative sensing plate, and the abutment block is provided at the position corresponding to the pressure sensor module.

[0015] The present invention also discloses a safety guardrail, including the aforementioned self-adjusting safety guardrail component, characterized in that the connecting frame is a right angle or a flat plate, a crossbeam is installed between two connecting frames, and the overall safety guardrail is composed of a plurality of connecting frames and a plurality of crossbeams.

[0016] In a preferred embodiment of the present invention, a rubber end cap is fitted onto the connecting frame located at the end, and the rubber end cap is fixedly disposed away from the end of the crossbeam.

[0017] In a preferred embodiment of the present invention, the pressure sensor module is electrically connected to an electrical control motherboard, which is located outside the safety guardrail and is integrated thereon. The electrical control motherboard is electrically connected to the cylinder, and all the electrical control motherboards are connected in series and then connected to an external 220V power supply.

[0018] The beneficial effects of this invention are:

[0019] 1. This self-adjusting safety protection component, through its multi-level buffer core structure, enables both the crossbeam and the connecting frame to have good buffering and energy absorption effects, resulting in high safety protection under impact.

[0020] 2. The overall safety guardrail incorporates a pressure sensor module connected to a cylinder within the crossbeam. When the crossbeam surface is impacted, the cylinder can be activated to adjust the distance between the contact arc plate and the first buffer core, thereby altering their deformation resistance. The greater the impact force, the smaller the distance between the contact arc plate and the first buffer core, resulting in a lower probability of deformation. Consequently, the crossbeam's resistance to bending increases, enabling it to autonomously adjust its buffering and energy absorption capacity based on pressure changes.

[0021] 3. Set up a cooperative sensing plate. The cooperative sensing plate can be bent at the same position. At this time, the bending of the cooperative sensing plate will affect the middle position of the cooperative sensing plate. Then, set up an abutment block so that different parts of the crossbeam are subjected to force, which can trigger the pressure sensor module. Attached Figure Description

[0029] To further understand the invention's content, features, and effects, the following embodiments are provided, and detailed descriptions are given in conjunction with the accompanying drawings.

[0030] Please also refer to Figures 1 to 6 The self-adjustable safety protection component and the safety guardrail it constitutes according to the embodiments of the present invention will be described in detail below with reference to the accompanying drawings. This bracket can be used in conjunction with the lifting structure.

[0031] like Figure 1 As shown, the self-adjusting safety protection component and the safety guardrail it constitutes include a connecting frame 1 and a crossbeam 2 detachably connected to the connecting frame 1. A first buffer core 3 is fixed inside the connecting frame 1 with screws. A connecting buffer body 4 is sleeved on the outside of the first buffer core 3. The crossbeam 2 is inserted and installed between the two connecting bodies. A self-adjusting component is provided inside the connecting body. The self-adjusting component includes an abutting arc plate 5 that slides inside the connecting buffer body 4, and a pressure sensor module 6 installed inside the crossbeam 2.

[0032] The connecting buffer body 4 has a T-shaped structure. A plug-in interface 7 is provided on one side of the connecting buffer body 4. The two ends of the crossbeam 2 are trapezoidal and are plugged into the plug-in interface 7. A waist-shaped travel groove 8 is provided on the side of the plug-in interface 7. A screw is inserted into the travel groove 8 and the crossbeam 2 is locked by the screw.

[0033] The first buffer core 3 has connecting ring blocks 14 snapped at both ends, and the connecting ring blocks 14 are fixedly connected to the connecting frame 1 with screws.

[0034] During installation, firstly, the connecting ring block 14 is inserted into both ends of the first buffer core 3. Then, the first buffer core 3 is placed in the installation position. The connecting ring block 14 on the first buffer core 3 is fastened to the through hole position on the connecting frame 1 with screws. Then, both ends of the crossbeam 2 are inserted into the insertion interface 7 on the connecting buffer body 4. After insertion, screws are used to fasten the crossbeam 2 to the connecting frame 1. At the same time, a certain stroke groove 8 is provided at the screw connection between the insertion interface 7 and the crossbeam 2.

[0035] The self-adjusting component also includes a connecting seat 9 fixed inside the contact arc plate 5. A moving rod 10 is fixed inside the connecting seat 9. The end of the moving rod 10 away from the contact arc plate 5 extends along one end of the connecting buffer body 4. A cylinder 11 is fixedly connected to the extended end of the moving rod 10. The cylinder 11 is electrically connected to the pressure sensor module 6. The connecting buffer body 4 is provided with a waist-shaped groove 12, which is used for sliding of the contact arc plate 5.

[0036] A spring 13 is sleeved on the outside of the moving rod 10. One end of the spring 13 is fixed to the inner wall of the connecting buffer body 4, and the other end is fixed to the connecting seat 9.

[0037] Furthermore, in the above structure, the crossbeam 2 receives the impact force. After being impacted, the crossbeam 2 bends, acting as the first buffer body. Due to the stroke groove 8 at the insertion interface 7, the bending of the crossbeam 2 causes the connecting buffer bodies 4 at both ends to move, while the first buffer core 3 remains fixed. Therefore, the connecting buffer body 4 moves relative to the first buffer core 3. At this time, the internal abutting arc plate 5 abuts against the side of the first buffer core 3. A pressure sensor module 6 is installed inside the crossbeam 2, located on the side of the crossbeam 2. When the surface is subjected to impact, it generates an electrical signal. Through the existing control module, the cylinder 11 can be opened. After the cylinder 11 is opened, the output end of the cylinder 11 moves towards the interior of the connecting buffer body 4, thereby changing the distance between the contact arc plate 5 and the first buffer core 3. The smaller the distance, the smaller the distance between the contact arc plate 5 and the first buffer core 3. Combined with the contraction of the spring 13, the deformation resistance between the contact arc plate 5 and the first buffer core 3 is stronger, thereby enhancing the overall energy absorption effect of the crossbeam 2.

[0038] In one embodiment, a support frame 15 is provided outside the pressure sensor, and the pressure sensor is snapped into the support frame 15. A second buffer core 16 is inserted into the end of the support frame 15 away from the pressure sensor module 6. A number of second buffer cores 16 are provided, and all of the second buffer cores 16 are inserted into the support frame 15. The pressure sensor module 6 is located in the middle of the crossbeam 2.

[0039] Inside the crossbeam 2, there is also a third buffer core 17. There are two third buffer cores 17 near both ends of the crossbeam 2. A cooperative sensing plate 18 is sleeved and fixed between the two third buffer cores 17. A contact block 19 is fixed on the cooperative sensing plate 18. The contact block 19 is set at the position corresponding to the pressure sensor module 6.

[0040] Specifically, in actual buffer protection, the surface of the crossbeam 2 is subjected to impact force, causing the crossbeam 2 to bend. At this time, the bending of the crossbeam 2 causes the internal cooperative sensing plate 18 to bend. Therefore, regardless of whether the crossbeam 2 bends in the middle or at the end, the cooperative sensing plate 18 can bend accordingly at the same position. At this time, the bending of the cooperative sensing plate 18 will affect the middle position of the cooperative sensing plate 18. Then, a contact block 19 is set so that after the end of the crossbeam 2 is subjected to force, the contact effect of the pressure sensor module 6 surface can be enhanced, and an electrical signal can be generated, thereby controlling the cylinder 11 to work through the existing control module.

[0041] The connecting buffer 4, crossbeam 2, first buffer core 3, second buffer core 16, and third buffer core 17 all use the buffer material developed by the applicant. Specifically, it is made by polymerizing and modifying imported European polymers into more than a dozen international standard environmentally friendly materials such as high-toughness polymers, antioxidants, ultraviolet absorbers, light stabilizers, antistatic agents, nucleating agents, and scratch-resistant agents to form the unique LB-FS2019 polymer material.

[0042] In another embodiment, a safety guardrail is provided, including the aforementioned self-adjusting safety guardrail component, wherein the connecting frame 1 is a right angle type or a flat plate type, and a crossbeam 2 is installed between two connecting frames 1. The overall safety guardrail is composed of a plurality of connecting frames 1 and a plurality of crossbeams 2.

[0043] A rubber end cap 20 is fitted onto the connecting frame 1 located at the end, and the rubber end cap 20 is fixedly installed away from the end of the crossbeam 2.

[0044] The pressure sensor module 6 is electrically connected to the electrical control motherboard, which is located outside the safety guardrail and is integrated. The electrical control motherboard is electrically connected to the cylinder 11, and all the electrical control motherboards are connected in series and then connected to an external 220V power supply.

[0045] The safety guardrail consists of multiple connecting frames 1 and crossbeams 2. Each connecting frame 1 is equipped with a connecting buffer 4. For safety protection at corners, right-angle connecting frames 1 can be used for installation. All electrical control boards are centrally managed and powered. The control wires of the pressure sensor module 6 and the cylinder 11 can extend along the crossbeams 2 and be integrated into the electrical control board. Thus, each crossbeam 2 can be autonomously adjusted to change its buffering and energy absorption capacity according to pressure changes.

[0046] In this embodiment, the pressure sensor module used is model JY-PS040. Its control principle for controlling the cylinder with electrical signals is based on existing technology, using the control module as a control intermediary.

[0047] Notably, when used as a safety barrier, the bottom of each connecting frame can be fixed to the ground with bolts.

[0048] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
