Description

Technical Field

[0001] The present invention relates to the technical field of acrylic plate transportation, and particularly to a transportation auxiliary device for extra-large acrylic plates. Background Art

[0002] Due to its excellent light transmittance, light weight and weather resistance, acrylic plates are widely used in fields such as architectural decoration, advertising display, and furniture manufacturing. However, extra-large acrylic plates (such as plates with a length exceeding 3 meters and a thickness of more than 5 mm) are prone to cracking, scratching or edge damage during transportation due to external force impact, vibration or improper clamping. Therefore, a special transportation auxiliary device is needed to provide stable support and buffer protection. Currently, common transportation methods include wooden frames, foam-filled boxes or simple metal brackets, but there is still much room for optimization in terms of safety, operation convenience and adaptability.

[0003] Existing transportation devices mostly adopt fixed support structures, such as rigid partitions combined with local foam pads. Although they can provide basic protection, the plates need to be manually lifted and placed during loading and unloading, which is cumbersome and prone to breakage due to uneven stress. Some improved solutions use roller-assisted propulsion, but the rollers cannot be automatically retracted during transportation, resulting in the plates being prone to displacement or collision with the box during bumpy rides. In addition, traditional clamping mechanisms are mostly rigid jigs, which only apply dot-like pressure to the edges of the plates, easily causing stress concentration. Especially for thin or extra-large acrylic plates, the risk of edge cracking is relatively high. Existing buffer designs mostly rely on single airbags or foam filling, unable to balance dynamic load-bearing and vibration absorption, and difficult to effectively suppress resonance effects during long-distance transportation. The box structure generally lacks adjustment capabilities, making it difficult to adapt to the transportation needs of different sizes or quantities of plates, and most solutions do not achieve full-surface soft protection, and there is still a risk of local impact at the four corners and edges of the plates.

[0004] How to solve the above technical problems is the subject faced by the present invention. Summary of the Invention

[0005] In order to solve the deficiencies of the prior art, the present invention provides a transportation auxiliary device for extra-large acrylic plates that realizes easy loading and unloading and stable fixation of acrylic plates through inflatable lifting rollers and buffer airbags, provides double buffering, adjustable layers and sizes, and realizes efficient transportation and comprehensive protection.

[0006] The technical solution adopted by the present invention to solve its technical problems is: The present invention provides a transportation auxiliary device for extra-large acrylic plates, including a box body, wherein a plurality of layers of fixing plates are arranged inside the box body, and clamping mechanisms are arranged on both sides of the top of each layer of fixing plate; The fixing plate includes a honeycomb support structure, and a transportation unit and an inflation unit are arranged inside the honeycomb support structure. The transportation unit includes rollers, and the rollers are slidably connected to the honeycomb support structure; The inflatable unit includes a number of upper airbags and lower airbags. The upper airbag includes a support airbag and a buffer airbag, and the support airbag and the buffer airbag share the same inflation system.

[0007] The box body includes a top plate, a bottom plate, a rear plate and side plate strips on both sides; A box door is provided on the front side of the box body.

[0008] The fixing plate includes receiving plates at both front and rear ends and a number of support plates in the middle. The receiving plates and the support plates are evenly arranged and parallel to each other; A number of connecting rods are fixedly connected between the receiving plate and the support plate.

[0009] Vertical plates perpendicular to the receiving plate are provided at both ends of the receiving plate, and vertical plates perpendicular to it are also provided on the side of the support plate close to the inner wall of the box body. The top and bottom surfaces of the vertical plates of each fixing plate are respectively in contact with the adjacent fixing plates; The clamping mechanism is connected to the inside of the vertical plate.

[0010] The clamping mechanism includes two groups of clamping plates, and the two groups of clamping plates are respectively located inside the vertical plates on both sides of the fixing plate; Each group of clamping plates is fixedly connected by a connecting rod. The clamping plates are parallel to the vertical plates and each clamping plate corresponds to one vertical plate; The clamping plates at both ends of each group of clamping plates are slidably connected to the receiving plate. The inside of the receiving plate is a hollow structure. A threaded rod parallel to the receiving plate is rotatably connected inside the receiving plate. A driving motor is coaxially arranged in the middle of the threaded rod. The thread teeth on the rod bodies of the threaded rod on both sides of the driving motor are symmetrically arranged. Sliders are respectively symmetrically threadedly connected to the rod bodies on both sides of the threaded rod. The slider is a T-shaped structure. The slider passes through a chute opened on the top surface of the receiving plate and is fixedly connected to the bottom of the clamping plate; The two driving motors on each fixing plate are synchronously electrically connected; A soft pad is provided on the inner side of each clamping plate.

[0011] The honeycomb support mechanism is provided on the top and bottom surfaces of each receiving plate and support plate. The honeycomb support mechanism includes a number of evenly arranged honeycomb-shaped support rings. The transportation unit and the inflatable unit are arranged in some of the honeycomb-shaped support rings, and the honeycomb-shaped support rings provided with the transportation unit and the inflatable unit are evenly arranged.

[0012] Symmetrical lifting grooves are provided on the inner wall of the honeycomb-shaped support ring. Lifting shafts are slidably connected in the lifting grooves. The two ends of the lifting shaft are cross-shaped structures and are slidably matched with the lifting grooves; The middle part of the lifting shaft is connected to the roller by a bearing.

[0013] The upper airbag is arranged inside the honeycomb support ring on the top surface of the fixed plate, and the lower airbag is arranged inside the honeycomb support ring on the bottom surface of the fixed plate; The support airbag is located below each buffer airbag, and the support airbag is located on the remaining inner walls of the honeycomb support ring where the lifting grooves are not provided; When the support airbag is inflated, the buffer airbag deflates.

[0014] The lower airbag is located in the middle of the honeycomb support ring.

[0015] A soft pad is arranged on the top surface of each honeycomb support ring.

[0016] The beneficial effects of the present invention are as follows: The present invention controls the lifting of the rollers through the inflation unit, and the acrylic plate can be easily pushed into the designated position inside the box by sliding on the rollers, greatly reducing the difficulty of manual handling. The alternating inflation and deflation mechanism of the support airbag and the buffer airbag enables the seamless switching of the plate from the transportation state supported by the rollers to the fixed state supported by the buffer airbag, which not only simplifies the operation process but also avoids the risk of surface scratches caused by the displacement of the plate; The clamping mechanism of the present invention adopts a symmetric screw drive design, uniformly presses through the contact surface of the soft pad, adapts to acrylic plates of different thicknesses without local stress concentration. The linkage structure between the clamping plate and the vertical plate ensures the clamping force while avoiding the edge cracking of the plate caused by rigid clamping, and further disperses the pressure in cooperation with the soft pad on the top of the honeycomb support ring, especially suitable for the protection of large-area acrylic plates that are easily scratched; Soft pads are arranged on the inner sides of the box door and the bottom plate of the present invention, and the vertical plates on both sides are evenly arranged. Compared with the current transportation box that only protects the four corners, the present invention realizes the buffer protection of the entire surface of the acrylic plate. When the traditional transportation box is jolted or vibrated, the edges and four corners of the plate are prone to cracking due to concentrated stress. However, the soft pads of the present invention cover the entire contact surface, can evenly disperse the impact force, and effectively avoid the risk of damage caused by excessive local stress. In addition, the uniform distribution of the vertical plates further enhances the integrity of the box structure and prevents the plate from undergoing lateral displacement or collision during transportation; The layered and independent lower airbag inflation system of the present invention can provide dynamic buffering for the lower-layer plates during transportation, adaptively offset the jolt impact through gas pressure. The buffer airbag and the lower airbag achieve the physical isolation of the load-bearing and energy-absorbing functions, and are more effective in suppressing vibration transmission than a single airbag structure, reducing the probability of the plate cracking due to resonance; The detachable connection design of the fixed plate and the box of the present invention is convenient for adjusting the number of layers according to transportation needs. The functional units in the honeycomb support structure can be increased or decreased in proportion to adapt to different sizes of plates. On the premise of ensuring the core functions, the present device reduces the manufacturing cost through standardized components; The honeycomb structure of the present invention has extremely high compressive and bending strengths, which can provide a stable support base for the airbag, prevent the airbag from shifting or collapsing during inflation and deflation, ensure that the plate is always in a horizontal state. If the airbag fails under extreme conditions (such as air leakage or abnormal air pressure), the honeycomb support ring of the present invention can still provide basic support through the soft pad on its top, preventing the plate from directly hitting the hard structure, forming a double protection mechanism.

Vertical plates 204 perpendicular to the receiving plate 201 are provided at both ends of the receiving plate 201. Vertical plates 204 perpendicular to the inner wall of the box body 1 are also provided on the side of the support plate 201 close to the inner wall of the box body 1. The top and bottom surfaces of the vertical plates 204 of each fixed plate 2 are respectively abutted against the adjacent fixed plates 2. The clamping mechanism is connected to the inner side of the vertical plate 204. The clamping mechanism includes two groups of clamping plates 6. The two groups of clamping plates 6 are respectively located inside the vertical plates 204 on both sides of the fixed plate 3. Each group of clamping plates 6 is fixedly connected by a connecting rod 203. The clamping plates 6 are parallel to the vertical plate 3 and each clamping plate 6 corresponds to a vertical plate 204. The clamping plates 6 at both ends of each group of clamping plates 6 are slidably connected to the receiving plate 201. The inside of the receiving plate 201 is a hollow structure. A threaded rod 601 parallel to the receiving plate 201 is rotatably connected inside the receiving plate 201. A driving motor 602 is coaxially arranged in the middle of the threaded rod 601. The thread teeth on the rod bodies of the threaded rod 601 on both sides of the driving motor 602 are symmetrically arranged. Slide blocks 603 are symmetrically threaded on both sides of the rod body of the threaded rod 601. The slide block 603 is of a T-shaped structure. The slide block 603 penetrates through a chute 604 opened on the top surface of the receiving plate 201 and is fixedly connected to the bottom of the clamping plate 6. The two driving motors 602 on each fixed plate 2 are synchronously electrically connected. A soft pad is provided on the inner side of each clamping plate 6.

[0028] The fixed plate 2 includes a honeycomb support structure 3. A transportation unit and an inflation unit are arranged inside the honeycomb support structure 3. The transportation unit includes rollers 4. The rollers 4 are slidably connected to the honeycomb support structure 3. The inflation unit includes a number of upper air bags and lower air bags 501. The upper air bag 5 includes a support air bag 5 and a buffer air bag 502. The support air bag 5 and the buffer air bag 502 share the same inflation system.

[0029] Each of the receiving plates 201 and the top and bottom surfaces of the support plate 202 are provided with the honeycomb support mechanism 3. The honeycomb support mechanism 3 includes a number of honeycomb-shaped support rings 301 arranged uniformly. The transportation unit and the inflation unit are arranged in some of the honeycomb-shaped support rings 301, and the honeycomb-shaped support rings 301 provided with the transportation unit and the inflation unit are arranged uniformly. Symmetrical lifting grooves 302 are provided on the inner wall of the honeycomb-shaped support ring 301. A lifting shaft 401 is slidably connected in the lifting groove 302. Both ends of the lifting shaft 401 are in a cross structure and are slidably matched with the lifting groove 302. The middle part of the lifting shaft 401 is connected by a bearing to the roller 4. The upper airbag is arranged in the honeycomb-shaped support ring 301 on the top surface of the fixing plate 3, and the lower airbag 501 is arranged in the honeycomb-shaped support ring 301 on the bottom surface of the fixing plate 3. The support airbag 5 is located below each of the buffer airbags 502. The support airbag 5 is located on the remaining inner wall of the honeycomb-shaped support ring 301 where the lifting groove 302 is not provided. When the support airbag 5 is inflated, the buffer airbag 502 deflates. The lower airbag 501 is located in the middle of the honeycomb-shaped support ring 301. A soft pad is provided on the top surface of each honeycomb-shaped support ring 301.

[0030] When the present invention is actually used: After opening the box door 101, the inflation system is used to inflate through the control panel, so that the support airbags 5 in the honeycomb-shaped support rings 301 at the top of each fixing plate 2 are filled with gas. During the inflation process, the four support airbags 5 in each honeycomb-shaped support ring 301 push up the lifting shaft 401, so that the wheel surface of the roller 4 is located above the honeycomb-shaped support ring 301, that is, above the plate surface of the fixing plate 2. At the same time, the buffer airbag 502 deflates. At this time, the acrylic plate can be transported to the innermost part above the fixing plate 2 through the several rollers 4 on the fixing plate 2. After determining the position, the support airbag 5 of this fixing plate 2 is deflated, and the gas flows to the buffer airbag 502. Since the buffer airbag 502 is located above the support airbag 5 and above the lifting shaft 401, when the lifting shaft 401 descends, the top surface of the buffer airbag 502 is located above the honeycomb-shaped support ring 301, that is, above the plate surface of the fixing plate 2, and the roller 4 returns to the inside of the honeycomb-shaped support ring 301. At this time, the acrylic plate will be located on the top surface of the buffer airbag 502. At this time, the driving motor 602 can be turned on through the control panel to rotate the threaded rod 601 to drive the sliders 603 on both sides and the clamping plates 6 to move symmetrically towards the acrylic plate. After clamping the acrylic plate, the movement can be stopped. After placing each layer of the fixing plate 2 in sequence, the lower airbag 501 can be inflated to buffer and protect the acrylic plate in the lower layer. The fixing plate 2 of the present invention is detachably connected to the box body 1.
