Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of building component transportation equipment, in particular to a transportation tool for transporting large-span prestressed wallboards. BACKGROUND

[0002] With the development of the building industry, large-span prestressed wallboards have been widely used in modern buildings due to their light weight, high strength, and fast construction efficiency. However, such wallboards are usually large in size and heavy in weight, and are prone to damage due to jolting, vibration, and mutual collision during transportation.

[0003] To solve the above problems, various transportation reinforcement equipment has appeared in the prior art. For example, a Chinese invention patent with the patent number CN221585504U discloses a "transportation matching reinforcement equipment for large-span wallboards". The equipment fixes the wallboard by setting a supporting seat, a pressing device, and a lateral jacking device on the transport vehicle. The supporting seat and the pressing device are usually complex frame structures and are adjusted in height and width by bolts and other fasteners.

[0004] However, the prior art solution has the following defects: Complex structure and numerous parts: the supporting and pressing mechanism is composed of multiple rod members, connecting members, and adjusting members, resulting in a complex overall structure, high manufacturing and assembly cost, and inconvenience for quick disassembly and assembly.

[0005] Insufficient buffering performance: the parts in contact with the wallboard are mostly rigid contact or only have simple gaskets in local parts, lacking systematic and comprehensive elastic buffering design, and the wallboard may still be damaged in severe jolting.

[0006] Adjustment and stacking are inconvenient: although adjustment is possible, the adjustment process usually requires turning multiple bolts, which is tedious. The structural design also does not facilitate quick and stable stacking of multiple layers of wallboards.

[0007] Therefore, designing a large-span prestressed wallboard transportation tool with a more compact structure, superior buffering performance, more convenient adjustment, and the ability to accommodate multiple layers of stacking is still a technical problem that needs to be solved in the field. SUMMARY

[0008] (I) Technical problems to be solved The purpose of the present application is to overcome the defects of complex structure, insufficient buffering, and inconvenient adjustment in the prior art for transporting large-span prestressed wallboards, and to provide a transportation tool with a compact structure, stable and reliable, superior buffering performance, and flexible adjustment to accommodate multiple layers of stacking. To this end, the present application makes the following targeted design: Linearly distributed side mounting pieces and middle mounting brackets are used to form a multi-point, symmetrical supporting and clamping structure, replacing a complex frame support, and the structure is more stable and has fewer parts.

[0009] The main and auxiliary buffers are designed as a modular structure that can be stacked in multiple layers, and the number of layers can be adjusted by simple plug-in cooperation, which is much easier than the tedious adjustment by bolts in the prior art.

[0010] Elastic buffer pads are arranged at all key positions in contact with the wallboard, including the contact surfaces and stacking surfaces of the main and auxiliary buffers, to form all-around buffer protection, solving the problem of insufficient buffering in the prior art.

[0011] A top limiting mechanism is added to effectively constrain the uppermost wallboard during transportation, especially for jolting and jumping, to ensure transportation safety.

[0012] (II) Technical solutions To achieve the above object, the present application provides the following technical solutions: A large-span prestressed wallboard transportation tool includes a vehicle plate, side mounting pieces, main buffers, mounting brackets, auxiliary buffers, and a front bumper.

[0013] A plurality of side mounting pieces are arranged on both sides of the vehicle plate and are linearly distributed to support and position the wallboard from both sides. The main buffers cooperate with the side mounting pieces to bear the weight of the wallboard and provide buffering. The mounting brackets are arranged on one side of the vehicle plate and are located at the middle position between adjacent side mounting pieces to mount the auxiliary buffers. The auxiliary buffers cooperate with the mounting brackets to assist in clamping and buffering the wallboard from the side. The front bumper is arranged at one end of the vehicle plate to limit the end of the wallboard.

[0014] Further, the side mounting piece includes an L-shaped plate, a rectangular pad A, a slot A, and an elastic buffer pad. The rectangular pad A is arranged on one side of the top of the L-shaped plate to increase the contact area with the main buffer. The slot A is opened in the top edge of the L-shaped plate to plug-in cooperate with the main buffer. A plurality of mounting holes are also opened in the side of the L-shaped plate to fix the side mounting piece on the vehicle plate by bolts.

[0015] Further, the main buffer includes a straight plate, a plug-in plate, a slot B, and a rectangular pad B. The plug-in plate is arranged at the bottom of the straight plate to plug-in with the slot A of the side mounting piece or the slot B of another main buffer. The slot B is opened at the top of the straight plate to realize the multi-layer stacking of the main buffer. The rectangular pad B is arranged on one side of the straight plate to directly contact and support the wallboard. The upper and lower surfaces of the rectangular pad B and the side of the straight plate facing the rectangular pad B are provided with elastic buffer pads to maximize the buffering effect and avoid damage to the wallboard.

[0016] Further, the main buffer can be matched with the slot B of another main buffer through the insertion plate to realize multi-layer stacking, thereby meeting the stacking requirements of wallboards of different layers.

[0017] Further, the auxiliary buffer comprises a straight rod, a convex column, a groove, a supporting rod and a circular pad. The convex column is arranged at the bottom end of the straight rod, and the groove is arranged at the top of the straight rod. The convex column is used for being inserted into the mounting seat or being inserted into another auxiliary buffer when stacking. The supporting rod is arranged at one side of the top of the straight rod, and the circular pad is arranged at one end of the supporting rod and used for abutting against the wallboard from the side. The circular pad is provided with elastic buffer pads on two sides, one side is used for buffering the contact with the wallboard, and the other side is used for buffering the contact with another auxiliary buffer when stacking.

[0018] Further, the elastic buffer pad is a polyurethane elastomer, which has excellent elasticity, wear resistance and aging resistance and can provide long-term and effective buffer protection.

[0019] Further, the auxiliary buffer can be matched with the groove of another auxiliary buffer through the convex column to realize multi-layer stacking, thereby matching the stacking layers of the main buffer and ensuring that effective lateral buffering and clamping can be provided for each layer of wallboard.

[0020] (Three) beneficial effects Compared with the prior art, the present application has the following beneficial effects: The structure is simple, and the present application is easy to manufacture and use: the complex frame structure is abandoned, the modular insertion design is adopted, the number of parts is small, the structure is clear, and the present application is easy to standardize production, assembly and maintenance. The loading and unloading process is convenient, and the working efficiency can be effectively improved.

[0021] The buffering performance is comprehensive and excellent: the elastic buffer pads are arranged in all key positions where the main buffer and the auxiliary buffer contact the wallboard, forming 360-degree buffer protection without dead angles, and the vibration and impact energy in the transportation process can be maximally absorbed, which is much better than the local buffering effect of the prior art.

[0022] The adaptability is high, and the universality is good: the main buffer and the auxiliary buffer are designed as a modular structure that can be stacked in multiple layers, and the actual stacking layers of the wallboard can be flexibly adjusted through simple insertion and extraction, which is much better than the complicated operation of screwing multiple bolts in the prior art, and the application range and loading efficiency of the transportation tool are greatly improved.

[0023] The structure is stable and fixed: through the side mounting pieces on both sides of the wallboard and the mounting seat in the middle, the main buffer and the auxiliary buffer are matched to form omnibearing surrounding fixation of the wallboard from the bottom, the side and the end. In particular, the top limiting design can effectively prevent the wallboard from jumping during transportation, thereby ensuring the transportation safety. BRIEF DESCRIPTION OF DRAWINGS

DETAILED DESCRIPTION

[0030] The invention will be further described in detail below in conjunction with the drawings and specific examples.

[0031] As shown in Figure 1 and Figure 2 , the large-span prestressed wall plate transport tool of the invention is mainly composed of a vehicle plate 1, a side mount 2, a main buffer 3, a mounting bracket 4, an auxiliary buffer 5, and a front baffle 6.

[0032] The vehicle plate 1 serves as the basic load-bearing component of the entire transport tool. On both sides of the vehicle plate 1, a plurality of side mounts 2 are installed through fasteners such as bolts, and these side mounts 2 are linearly and uniformly distributed along the length direction of the vehicle plate. On one side of the vehicle plate 1 and at the middle position between every two adjacent side mounts 2, a mounting bracket 4 is arranged. The front baffle 6 is fixedly installed at the front end of the vehicle plate 1.

[0033] As shown in Figure 3 , the side mount 2 is in the overall L-shaped structure, and the vertical surface of the L-shaped plate 21 is provided with a mounting hole 24 for connection with the vehicle plate 1. The horizontal top surface of the L-shaped plate 21 is welded or bolted with a rectangular pad A 22 on one side, and the edge of the top surface is provided with a slot A 23.

[0034] As shown in Figure 4As shown, the straight plate 31 of the main buffer 3 is provided with an insertion plate 32 extending downward at the bottom and an insertion slot B33 at the top. The straight plate 31 is provided with a rectangular pad B34 at one side. The upper and lower surfaces of the rectangular pad B34 and the side of the straight plate 31 facing the rectangular pad B34 are all pasted or vulcanized with elastic buffer pads 25 made of polyurethane elastomer.

[0035] As shown, Figure 5 the straight rod 51 of the auxiliary buffer 5 is provided with a protruding column 52 at the bottom end and a recess 53 at the top end. The upper side of the straight rod 51 is provided with an outwardly extending support rod 54, and the end of the support rod 54 is provided with a circular pad 55. The two end faces of the circular pad 55 are also provided with elastic buffer pads 25.

[0036] The assembly and use process is as follows: Basic installation: first, all the side installation pieces 2 and the installation clamps 4 are fixedly installed on the vehicle plate 1 according to the predetermined position.

[0037] Place the first layer of wallboards: hoist the first wallboard onto the vehicle plate 1, with the bottom edge placed on the rectangular pad A22 of the corresponding side installation piece 2.

[0038] Install the first layer of buffers: Insert the insertion plate 32 of the main buffer 3 into the insertion slot A23 of the side installation piece 2, so that the elastic buffer pads 25 on the rectangular pad B34 tightly abut against the side surface of the wallboard.

[0039] Insert the protruding column 52 of the auxiliary buffer 5 into the installation clamp 4, so that the elastic buffer pads 25 on the circular pad 55 abut against the wallboard from the other side. By adjusting the positions of the main and auxiliary buffers, the wallboard is preliminarily clamped.

[0040] Stack the second layer of wallboards: hoist the second wallboard above the first wallboard.

[0041] Take a new main buffer 3 and insert the insertion plate 32 into the insertion slot B33 of the first layer of main buffers 3, so that the rectangular pad B34 tightly abuts against the side surface of the second layer of wallboards.

[0042] Take a new auxiliary buffer 5 and insert the protruding column 52 into the recess 53 of the first layer of auxiliary buffers 5, so that the circular pad 55 abuts against the second layer of wallboards from the other side.

[0043] Repeat the operation: according to the total number of wallboards to be stacked, repeat step 4 to stack the wallboards and buffers layer by layer until the desired height is reached.

[0044] End limiting: after all the wallboards are stacked, the front ends of the wallboards are in contact with the front stop plate 6, achieving end limiting and buffering.

[0045] Top layer height limiting and anti-jumping operation: In order to prevent the wallboard from jumping upward due to bumps during transportation, especially the uppermost wallboard, additional height limiting and anti-jumping fixing need to be performed: Set the limiting rod: On the straight plate 31 of the uppermost main buffer 3, a limiting hole can be pre-drilled. After the wallboard is stacked, a horizontal rod or steel cable with adjustable length is passed through the limiting holes of the corresponding main buffers 3 on both sides and is fixed. This horizontal rod or steel cable will cross the top of the wallboard, forming a physical "ceiling" that limits the upward displacement of the wallboard.

[0046] Use the binding belt: Use a high-strength flexible binding belt to diagonally or longitudinally bind the uppermost wallboard with the front end of the vehicle plate or the side mounting part 2 of the transportation tool. The binding belt should be tensioned to ensure that the wallboard is firmly pressed on the support structure below, effectively preventing jumping.

[0047] In this way, the present application not only provides stable, safe and fully cushioned transportation protection for large-span prestressed wallboards, but also has high flexibility and universality due to its modular stacking design. Through special top layer height limiting operation, the absolute safety during transportation is further ensured.

[0048] Finally, it should be noted that the above examples are only used to illustrate the technical solutions of the present application, and are not intended to limit the scope of protection of the present application. Although the present application has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present application can be modified or replaced by equivalents without departing from the essence and scope of the technical solutions of the present application.
