Description

Technical Field

[0001] This invention relates to the field of building component transportation equipment, and in particular to a transportation tool for transporting large-span prestressed wall panels. Background Technology

[0002] With the development of industrialized construction, large-span prestressed wall panels have been widely used in modern buildings due to their advantages such as light weight, high strength, and fast construction efficiency. However, these wall panels are usually large in size and heavy in weight, making them extremely susceptible to damage during transportation due to bumps, vibrations, and collisions.

[0003] To address the aforementioned problems, various transportation reinforcement devices have emerged in the prior art. For example, Chinese invention patent CN221585504U discloses a "transportation and reinforcement device for large-span wall panels." This device secures the wall panels by installing support seats, clamping devices, and lateral clamping devices on a transport vehicle. Its support seats and clamping devices are typically complex frame structures, and their height and width are adjusted using fasteners such as bolts.

[0004] However, this existing technical solution has the following drawbacks: Its complex structure and numerous parts: its support and clamping mechanism consists of multiple rods, connectors and adjusting parts, resulting in a complex overall structure, high manufacturing and assembly costs, and inconvenience for quick loading and unloading.

[0005] Insufficient cushioning performance: The parts that come into contact with the wall panel are mostly rigid or only have simple pads in some areas. They lack a systematic and comprehensive elastic cushioning design, and may still damage the wall panel during severe bumps.

[0006] Inconvenient adjustment and stacking: Although it can be adjusted, the adjustment process usually requires turning multiple bolts, which is cumbersome. Its structural design also makes it difficult to achieve rapid and stable stacking of multi-layer wall panels.

[0007] Therefore, designing a transportation tool for large-span prestressed wall panels that is more streamlined in structure, has better cushioning performance, is more convenient to adjust, and can adapt to multi-layer stacking remains a technical problem that urgently needs to be solved in this field. Summary of the Invention

[0008] (a) Technical problems to be solved The purpose of this invention is to overcome the shortcomings of existing technologies in transporting large-span prestressed wall panels, such as complex structure, insufficient cushioning, and inconvenient adjustment, and to provide a transportation tool with a simplified structure, robust reliability, excellent cushioning performance, and flexible adjustment to adapt to multi-layer stacking. To this end, this invention incorporates the following targeted designs: By employing linearly distributed side mounting components and central mounting brackets, a multi-point, symmetrical support and clamping structure is formed, replacing the complex frame-type support, resulting in a more stable structure with fewer parts.

[0009] The main and secondary buffer components are designed as a modular structure that can be stacked in multiple layers. The number of layers can be adjusted by simple plug-in connection, which is far superior to the cumbersome adjustment by bolts in the existing technology.

[0010] Elastic buffer pads are installed at all critical points in contact with the wall panel (including the contact surfaces and overlapping surfaces of the main and secondary buffer components) to form all-round buffer protection, solving the problem of insufficient buffering in existing technologies.

[0011] A top-level limiting mechanism has been added to specifically address bumps and vibrations during transportation, particularly to effectively restrain the topmost wall panel and ensure transportation safety.

[0012] (II) Technical Solution To achieve the above objectives, the present invention provides the following technical solution: A large-span prestressed wall panel transport vehicle includes a vehicle platform, side mounting components, a main buffer component, a mounting bracket, a secondary buffer component, and a front baffle.

[0013] Several side mounting members are provided on both sides of the vehicle panel, arranged linearly, to support and position the wall panel from both sides. The main buffer member cooperates with the side mounting members to bear the weight of the wall panel and provide cushioning. The mounting bracket is located on one side of the vehicle panel, in the middle of the adjacent side mounting members, and is used to install the secondary buffer member. The secondary buffer member cooperates with the mounting bracket to assist in clamping and cushioning the wall panel from the side. The front baffle is located at one end of the vehicle panel to limit the end position of the wall panel.

[0014] Furthermore, the side mounting component includes an L-shaped plate, a rectangular pad A, a slot A, and an elastic buffer pad. The rectangular pad A is disposed on the top side of the L-shaped plate to increase the contact area with the main buffer component. The slot A is formed on the top edge of the L-shaped plate for insertion and mating with the main buffer component. Several mounting holes are also formed on the side of the L-shaped plate for fixing the side mounting component to the vehicle panel with bolts.

[0015] Furthermore, the main buffer component includes a straight plate, an insert plate, a slot B, and a rectangular pad B. The insert plate is located at the bottom of the straight plate and is used to connect with the slot A of the side mounting component or the slot B of another main buffer component. The slot B is located at the top of the straight plate to allow for multi-layer stacking of the main buffer components. The rectangular pad B is located on one side of the straight plate and is used to directly contact and support the wall panel. Elastic buffer pads are provided on the top and bottom surfaces of the rectangular pad B, as well as on the side of the straight plate facing the rectangular pad B, to maximize the buffering effect and prevent damage to the wall panel.

[0016] Furthermore, the main buffer can be coupled with the slot B of another main buffer through a plug plate to achieve multi-layer stacking, thereby adapting to the stacking requirements of wall panels with different numbers of layers.

[0017] Furthermore, the secondary buffer component includes a straight rod, a protruding post, a groove, a support rod, and a circular pad. The protruding post is located at the bottom end of the straight rod, and the groove is located at the top of the straight rod. The protruding post is used to insert into a mounting bracket or to insert into another secondary buffer component when stacked. The support rod is located on one side of the top of the straight rod, and the circular pad is located at one end of the support rod, used to abut against the wall panel from the side. Both sides of the circular pad are provided with elastic buffer pads; one side is used to buffer contact with the wall panel, and the other side is used to buffer contact with another secondary buffer component when stacked.

[0018] Furthermore, the elastic cushioning pad is made of polyurethane elastomer, which has excellent elasticity, abrasion resistance and anti-aging properties, and can provide long-lasting and effective cushioning protection.

[0019] Furthermore, the secondary buffer can be coupled with the groove of another secondary buffer through a protrusion to achieve a multi-layer stacking arrangement, matching the number of stacking layers of the main buffer, ensuring that each wall panel can be effectively buffered and clamped.

[0020] (III) Beneficial Effects Compared with the prior art, the present invention has the following beneficial effects: Simplified structure, easy to manufacture and use: It abandons the complex frame structure and adopts a modular plug-in design, resulting in fewer parts, a clear structure, and easy standardized production, assembly, and maintenance. The loading and unloading process is convenient, effectively improving work efficiency.

[0021] Comprehensive and excellent cushioning performance: Elastic cushioning pads are systematically set at all key points where the main and secondary cushioning components contact the wall panel, forming 360-degree cushioning protection without dead angles. This can absorb vibration and impact energy during transportation to the maximum extent, far exceeding the local cushioning effect of existing technologies.

[0022] Highly adaptable and versatile: Both the main and secondary buffer components are designed as modular structures that can be stacked in multiple layers. They can be flexibly adjusted according to the actual number of stacked wall panels by simple plugging and unplugging. The adjustment method is far superior to the cumbersome operation of turning multiple bolts in the existing technology, which greatly improves the applicability and loading efficiency of the transport vehicle.

[0023] The structure is robust and securely fixed: Side mounting brackets on both sides of the vehicle panel and a central mounting bracket, along with main and auxiliary buffer components, provide comprehensive, enveloping fixation to the wall panel from the bottom, sides, and ends. In particular, the added top-level limiting design effectively prevents the wall panel from jumping during transportation, ensuring transport safety. Attached Figure Description

[0030] Example 1: The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0031] like Figure 1 and Figure 2 As shown, the large-span prestressed wall panel transport vehicle of the present invention mainly consists of a vehicle platform 1, a side mounting component 2, a main buffer component 3, a mounting bracket 4, a secondary buffer component 5, and a front baffle 6.

[0032] The platform 1 serves as the basic load-bearing component of the entire transport vehicle. Several side mounting pieces 2 are installed on both sides of the platform 1 using bolts or other fasteners, and these side mounting pieces 2 are linearly and evenly distributed along the length of the platform. On one side of the platform 1, at the midpoint between every two adjacent side mounting pieces 2, a mounting bracket 4 is provided. The front baffle 6 is fixedly installed at the front end of the platform 1.

[0033] like Figure 3 As shown, the side mounting component 2 has an overall L-shaped structure, and mounting holes 24 are provided on the vertical surface of its L-shaped plate 21 for connection with the vehicle plate 1. A rectangular pad A22 is welded or bolted to one side of the horizontal top surface of the L-shaped plate 21, and a slot A23 is provided on the edge of the top surface.

[0034] like Figure 4As shown, the bottom of the straight plate 31 of the main buffer 3 is provided with a downwardly extending insert plate 32, and the top is provided with a slot B33. A rectangular pad B34 is provided on one side of the straight plate 31. Elastic buffer pads 25 made of polyurethane elastomer are attached or vulcanized on the upper and lower surfaces of the rectangular pad B34 and on the side of the straight plate 31 facing the rectangular pad B34.

[0035] like Figure 5 As shown, the bottom end of the straight rod 51 of the secondary buffer 5 is provided with a protrusion 52, and the top end is provided with a groove 53. A support rod 54 extending outward is provided on one side of the upper part of the straight rod 51, and a circular pad 55 is provided at the end of the support rod 54. The two end faces of the circular pad 55 are also provided with elastic buffer pads 25.

[0036] The assembly and usage process is as follows: Basic installation: First, fix all side mounting parts 2 and mounting brackets 4 on the vehicle plate 1 according to the preset positions.

[0037] Place the first wall panel: Hoist the first wall panel onto the vehicle platform 1, so that its bottom edge is placed on the rectangular pads A22 of the corresponding side mounting parts 2 on both sides.

[0038] Install the first layer of buffer: Insert the insert plate 32 of the main buffer 3 into the slot A23 of the side mounting 2, so that the elastic buffer pad 25 on its rectangular pad B34 is in close contact with the side of the wall panel.

[0039] Insert the protrusion 52 of the secondary buffer 5 into the mounting bracket 4, so that the elastic buffer pad 25 on its circular pad 55 presses against the wall panel from the other side. By adjusting the positions of the primary and secondary buffers, the wall panel is initially clamped.

[0040] Add a second layer of wall panels: hoist the second wall panel above the first wall panel.

[0041] Take the new main buffer 3 and insert its insert plate 32 into the slot B33 of the first layer main buffer 3, so that its rectangular pad B34 is in close contact with the side of the second layer wall panel.

[0042] Take a new secondary buffer 5 and insert its protrusion 52 into the groove 53 of the first secondary buffer 5, so that its circular pad 55 presses against the second wall panel from the other side.

[0043] Repeat the process: Based on the required total number of wall panels to be stacked, repeat step 4, stacking the wall panels and buffers layer by layer until the desired height is reached.

[0044] End limiting: After all wall panels are stacked, their front ends contact the front baffle 6 to achieve end limiting and buffering.

[0045] Top-floor height restriction and anti-jumping measures: To prevent the wall panels from jumping upwards during transportation, especially the topmost wall panels, additional height restriction and anti-jumping fixation are required. Setting a limiting rod: Limiting holes can be pre-drilled on the straight plate 31 of the uppermost main buffer component 3. After the wall panels are stacked, an adjustable-length horizontal bar or steel cable is passed through the corresponding limiting holes of the main buffer components 3 on both sides and fixed. This horizontal bar or steel cable will cross the top of the wall panels, forming a physical "ceiling" that restricts the upward displacement of the wall panels.

[0046] Use tie-down straps: Use high-strength, flexible tie-down straps to diagonally or longitudinally tie the uppermost wall panel to the front or side mounting bracket 2 of the transport vehicle. The tie-down straps should be taut to ensure the wall panel is firmly pressed against the supporting structure below, effectively preventing jumping.

[0047] In this way, the present invention not only provides a stable, safe and well-buried transportation guarantee for large-span prestressed wall panels, but its modular stacking design also gives it extremely high flexibility and versatility. Furthermore, through a special top-level height restriction operation, absolute safety during transportation is further ensured.

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