Description

Technical Field

[0001] This invention relates to the field of acrylic sheet transportation technology, and in particular to an auxiliary device for transporting ultra-large acrylic sheets. Background Technology

[0002] Acrylic sheets are widely used in architectural decoration, advertising displays, and furniture manufacturing due to their excellent light transmittance, lightweight, and weather resistance. However, extra-large acrylic sheets (such as sheets exceeding 3 meters in length and 5 mm in thickness) are susceptible to cracking, scratches, or edge damage during transportation due to external impacts, vibrations, or improper clamping. Therefore, specialized transportation aids are needed to provide stable support and cushioning protection. Currently, common transportation methods include wooden frames, foam-filled boxes, or simple metal supports, but these solutions still have significant room for improvement in terms of safety, ease of operation, and adaptability.

[0003] Existing transport devices mostly employ fixed support structures, such as rigid partitions combined with localized foam padding. While these provide basic protection, manual lifting and unloading of the panels is cumbersome and prone to damage due to uneven stress. Some improved solutions use rollers for assisted propulsion, but these rollers cannot automatically retract during transport, causing the panels to easily shift or collide with the container during bumps. Furthermore, traditional clamping mechanisms are mostly rigid clamps, applying only point pressure to the edges of the panels, which can easily cause stress concentration, especially for thin or extra-large acrylic panels, resulting in a higher risk of edge breakage. Existing cushioning designs often rely on single airbags or foam filling, failing to balance dynamic load-bearing and vibration absorption. This makes it difficult to effectively suppress resonance effects during long-distance transport. Container structures generally lack adjustability, making it difficult to adapt to the transport needs of panels of different sizes or quantities. Moreover, most solutions do not achieve full-surface soft protection, leaving the corners and edges of the panels vulnerable to localized impact risks.

[0004] How to solve the above-mentioned technical problems is the challenge facing this invention. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides an auxiliary device for transporting ultra-large acrylic sheets. This device utilizes inflatable lifting rollers and cushioning airbags to facilitate easy loading, unloading, and stable fixing of acrylic sheets, providing dual cushioning, adjustable number of layers and size, and achieving efficient transportation and comprehensive protection.

[0006] The technical solution adopted by the present invention to solve its technical problem is: the present invention provides an auxiliary device for transporting ultra-large acrylic sheets, including a box, wherein a number of fixing plates are arranged inside the box, and clamping mechanisms are arranged on both sides of the top of each fixing plate. The fixing plate includes a honeycomb support structure, and a transport unit and an inflation unit are provided inside the honeycomb support structure. The transport unit includes rollers, and the rollers are slidably connected to the honeycomb support structure. The inflation unit includes several upper airbags and lower airbags. The upper airbags include support airbags and cushioning airbags. The support airbags and the cushioning airbags share the same inflation system.

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

[0008] The fixing plate includes receiving plates at the front and rear ends and several support plates in the middle. The receiving plates and the support plates are evenly distributed and arranged in parallel. Several connecting rods are fixedly connected between the receiving plate and the supporting plate.

[0009] Both ends of the receiving plate are provided with vertical plates perpendicular to the receiving plate, and the side of the support plate near the inner wall of the box is also provided with a vertical plate perpendicular to it. The top and bottom surfaces of the vertical plates of each fixing plate respectively abut against the adjacent fixing plate. The clamping mechanism is connected to the inner side of the upright plate.

[0010] The clamping mechanism includes two sets of clamping plates, which are respectively located in the two side uprights of the fixed plate; Each set of clamping plates is fixedly connected by a connecting rod. The clamping plates are parallel to the upright plates and each clamping plate corresponds to one upright plate. Each set of clamping plates is slidably connected to the receiving plate at both ends. The receiving plate has a hollow structure inside. A threaded rod parallel to the receiving plate is rotatably connected inside the receiving plate. A drive motor is coaxially arranged in the middle of the threaded rod. The threaded teeth of the threaded rod on both sides of the drive motor are symmetrically arranged. A slider is symmetrically threaded to each side of the threaded rod. The slider has a T-shaped structure and passes through a groove on the top surface of the receiving plate and is fixedly connected to the bottom of the clamping plate. The two drive motors on each of the fixed plates are synchronously electrically connected; Each of the clamping plates has a soft pad on its inner side.

[0011] Each of the receiving plates and the support plates has a honeycomb support mechanism on its top and bottom surfaces. The honeycomb support mechanism includes several uniformly arranged honeycomb support rings. Some of the honeycomb support rings contain the transport unit and the inflation unit, and the honeycomb support rings containing the transport unit and the inflation unit are uniformly arranged.

[0012] The inner wall of the honeycomb support ring is provided with symmetrical lifting grooves, and a lifting shaft is slidably connected in the lifting groove. The two ends of the lifting shaft are cross structures that slide with the lifting groove. The roller is connected to the bearing in the middle of the lifting shaft.

[0013] The upper airbag is disposed within the honeycomb-shaped support ring located on the top surface of the fixed plate, and the lower airbag is disposed within the honeycomb-shaped support ring located on the bottom surface of the fixed plate. The support airbag is located below each of the buffer airbags, and the support airbag is located on the remaining inner wall of the honeycomb support ring where the lifting groove is not provided; When the support airbag is inflated, the buffer airbag is deflated.

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

[0015] Each of the honeycomb support rings has a soft pad on its top surface.

[0016] The beneficial effects of the present invention are as follows: The present invention controls the lifting and lowering of the rollers through the inflation unit. The acrylic sheet can be easily pushed into the designated position inside the box by sliding with the help of the rollers, which greatly reduces the difficulty of manual handling. The alternating inflation and deflation mechanism of the support airbag and the buffer airbag allows the sheet to seamlessly switch from the transportation state, i.e., the roller support, to the fixed state, i.e., the buffer airbag support. This simplifies the operation process and avoids the risk of surface scratches caused by the displacement of the sheet. The clamping mechanism of this invention adopts a symmetrical thread drive design, which applies pressure evenly through the soft pad contact surface, adapts to acrylic sheets of different thicknesses and has no local stress concentration. The linkage structure between the clamping plate and the upright plate ensures the clamping force while avoiding edge breakage of the sheet caused by rigid clamping. The soft pad at the top of the honeycomb support ring further disperses the pressure, making it especially suitable for the protection of large-area acrylic sheets that are easily scratched. The present invention features soft pads on the inside of the door and bottom plate, and the uprights on both sides are evenly distributed. Compared with the current transport boxes that only protect the four corners, the present invention provides cushioning protection for the entire surface of the acrylic sheet. When traditional transport boxes are bumped or vibrated, the edges and four corners of the sheet are prone to cracking due to concentrated force. However, the soft pads of the present invention cover the entire contact surface, which can evenly distribute the impact force and effectively avoid the risk of damage caused by excessive local stress. In addition, the even distribution of the uprights further enhances the integrity of the box structure and prevents the sheet from lateral displacement or collision during transportation. The layered independent lower airbag inflation system of this invention can provide dynamic buffering for the lower sheet material during transportation. It can offset the impact of bumps by adaptively adjusting the gas pressure. The buffer airbag and the lower airbag achieve physical isolation of the load-bearing and energy absorption functions. Compared with a single airbag structure, it can more effectively suppress vibration transmission and reduce the probability of sheet material breaking due to resonance. The detachable connection design between the fixing plate and the box body of this invention makes it easy to adjust the number of layers according to transportation needs. The functional units in the honeycomb support structure can be increased or decreased proportionally to adapt to different sizes of plates. This device reduces manufacturing costs by using standardized components while ensuring the core functions. The honeycomb structure of this invention has extremely high compressive and bending strength, which can provide a stable support base for the airbag, prevent the airbag from shifting or collapsing during inflation and deflation, and ensure that the plate is always in a horizontal state. If the airbag fails in extreme cases (such as air leakage or abnormal air pressure), the honeycomb support ring of this invention can still provide basic support through the soft pad on its top, preventing the plate from directly impacting the rigid structure, forming a dual protection mechanism.

[0025] To clearly illustrate the technical features of this solution, the following detailed implementation method will be used to explain the solution.

[0026] See Figures 1 to 7As shown, this embodiment is an auxiliary device for transporting extra-large acrylic sheets, including a box body 1. The box body 1 includes a top plate, a bottom plate, a rear plate, and side plates on both sides. A box door 101 is provided on the front side of the box body 1. Several layers of fixing plates 2 are provided inside the box body 1. The fixing plates 2 include supporting plates 201 at the front and rear ends and several supporting plates 202 in the middle. The supporting plates 201 and the supporting plates 202 are evenly distributed and arranged in parallel. Several connecting rods 203 are fixedly connected between the supporting plates 201 and the supporting plates 202.

[0027] Each of the fixed plates 2 has a clamping mechanism on both sides of its top. The receiving plate 201 has vertical plates 204 perpendicular to it at both ends. The support plate 201 also has a vertical plate 204 perpendicular to it on the side closest to the inner wall of the housing 1. The top and bottom surfaces of the vertical plates 204 of each fixed plate 2 abut against the adjacent fixed plate 2. The clamping mechanism is connected to the inner side of each vertical plate 204. The clamping mechanism includes two sets of clamping plates 6, located within the vertical plates 204 on both sides of the fixed plate 3. Each set of clamping plates 6 is fixedly connected to the other two sets via connecting rods 203. The clamping plates 6 are parallel to the vertical plates 3, and each clamping plate 6 corresponds to one vertical plate 204. Each set of clamping plates... The clamping plates 6 located at both ends of the holding plate 6 are slidably connected to the receiving plate 201. The receiving plate 201 has a hollow internal structure. A threaded rod 601 parallel to the receiving plate 201 is rotatably connected inside the receiving plate 201. A drive motor 602 is coaxially arranged in the middle of the threaded rod 601. The threaded teeth of the threaded rod body on both sides of the drive motor 602 are symmetrically arranged. A slider 603 is symmetrically threaded to the two sides of the threaded rod 601. The slider 603 has a T-shaped structure. The slider 603 passes through the sliding groove 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 drive 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 fixing plate 2 includes a honeycomb support structure 3, and a transport unit and an inflation unit are provided inside the honeycomb support structure 3. The transport unit includes a roller 4, which is slidably connected to the honeycomb support structure 3. The inflation unit includes several upper airbags and lower airbags 501. The upper airbags 5 include a support airbag 5 and a buffer airbag 502. The support airbag 5 and the buffer airbag 502 share the same inflation system.

[0029] Each of the receiving plates 201 and the support plates 202 has a honeycomb support mechanism 3 on its top and bottom surfaces. The honeycomb support mechanism 3 includes several evenly arranged honeycomb-shaped support rings 301. Some of the honeycomb-shaped support rings 301 contain the transport unit and the inflation unit, and the honeycomb-shaped support rings 301 containing the transport unit and the inflation unit are evenly arranged. The inner wall of each honeycomb-shaped support ring 301 has symmetrical lifting grooves 302. A lifting shaft 401 is slidably connected within each lifting groove 302. The lifting shaft 401 has cross-shaped ends that slide in conjunction with the lifting groove 302. The roller 4 is connected to the central bearing of 01. The upper airbag is provided in the honeycomb support ring 301 located on the top surface of the fixed plate 3. The lower airbag 501 is provided in the honeycomb support ring 301 located on the bottom surface of the fixed 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 support ring 301 without the lifting groove 302. When the support airbag 5 is inflated, the buffer airbag 502 is deflated. The lower airbag 501 is located in the middle of the honeycomb support ring 301. The top surface of each honeycomb support ring 301 is provided with a soft pad.

[0030] In actual use, after opening the door 101, the inflation system is inflated via the control panel, filling the support airbags 5 in the honeycomb support rings 301 at the top of each fixed plate 2 with air. During inflation, the four support airbags 5 in each honeycomb support ring 301 push the lifting shaft 401 to lift, so that the roller 4 is positioned above the honeycomb support ring 301, i.e., above the fixed plate 2. At the same time, the buffer airbag 502 is deflated. At this point, the acrylic plate can be transported to the innermost part of the fixed plate 2 via the rollers 4 on the fixed plate 2. After determining the position, the support airbags 5 of this fixed plate 2 are deflated, and the gas flows to the buffer airbag 502. Since the buffer airbag 502 is located at the support airbag 502, the gas is deflated. Above the airbag 5 and above the lifting shaft 401, as the lifting shaft 401 descends, the top surface of the airbag 502 is above the honeycomb support ring 301, that is, above the surface of the fixing plate 2. The roller 4 returns to the inside of the honeycomb support ring 301. At this time, the acrylic plate will be located on the top surface of the airbag 502. At this time, the drive motor 602 can be turned on through the control panel to make the threaded rod 601 rotate and drive the sliders 603 on both sides and the clamping plate 6 to move symmetrically towards the acrylic plate. After clamping the acrylic plate, the movement can be stopped. After each layer of fixing plate 2 is placed in sequence, the lower airbag 501 can be opened to inflate and buffer and protect the lower acrylic plate. The fixing plate 2 of this invention is detachably connected to the box body 1.
