Description

Technical Field

[0001] The utility model relates to the technical field of automobile transportation, in particular to a double-layer automobile transportation frame. Background Art

[0002] Double-decker car transport, as an innovative technology in the modern logistics industry, has significantly improved transportation efficiency. It adopts a double-layer structure design, which enables the same transport vehicle to stack two layers of cars, thereby carrying more vehicles in one trip and effectively reducing transportation costs. This design not only improves logistics efficiency, but also helps alleviate urban traffic pressure.

[0003] The construction of double-decker car transporters takes full consideration of stability and safety. Through precision design, it ensures that the stacked vehicles will not slide or collide during transportation, greatly enhancing the reliability of transportation. In addition, the double-decker structure is compact, reducing space occupation, making long-distance transportation more efficient and economical.

[0004] However, despite the many advantages of double-decker car transport, there are still some challenges in practical application, especially in the design of safety systems. First, safety systems such as chains may cause excessive rotation during transportation due to factors such as road conditions, vehicle acceleration and deceleration, thereby increasing the risk of wear and damage to the equipment. Such wear and tear may accumulate over a long period of time and may reduce the performance of the equipment and even cause safety hazards.

[0005] Secondly, the lack of flexibility of existing safety systems is also worthy of attention. On the one hand, safety devices such as chains may be too rigid and unable to fully adapt to the complex shaking conditions during car transportation, which increases the risk of the car slipping or tipping over. On the other hand, these devices have a limited adjustment range and may not be able to adapt to cars of different sizes and weights, limiting the widespread application of double-layer car transport racks.

[0006] Therefore, while promoting double-decker car transport, we also need to pay attention to and address these potential safety and flexibility issues to ensure that it continues to serve the logistics industry in a stable and stable manner. Utility Model Content

[0007] The main purpose of the utility model is to provide a double-layer automobile transport rack, which can effectively solve the problems raised in the background technology.

[0008] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0009] A double-layer automobile transport rack comprises a transport vehicle body, a bottom placement plate, an upper placement plate, a protective roof, a side frame and a lifting device, wherein the bottom placement plate, the upper placement plate and the protective roof are sequentially arranged on the transport vehicle body from bottom to top, the bottom placement plate, the upper placement plate and the protective roof are supported and connected by the side frame, and the tails of the bottom placement plate and the upper placement plate are provided with lifting devices for automobile entry and exit, and the positions of the two sets of lifting devices are staggered;

[0010] The bottom placement plate and the upper placement plate are provided with displacement adjustment grooves, and a plurality of fixing tubes are inserted into the displacement adjustment grooves. The upper ends of the fixing tubes are provided with embedded holes, and chassis hooks are inserted into the embedded holes and fixed by locking components. The chassis hooks hook the automobile chassis on the placement plate to achieve safe hanging.

[0011] The tube wall of the fixing tube is sleeved with a first cross fastener and a second cross fastener, which restrict the fixing tube from falling out of the displacement adjustment groove. The movable range of the fixing tube is restricted by a horizontal bar in the displacement adjustment groove, so as to protect the connection between the chassis hook and the chassis when the car shakes.

[0012] As a further preferred embodiment of the present invention, the end faces of the first cross fastener and the second cross fastener are provided with waist holes, which are aligned with the waist holes provided on the bottom placement plate or the upper placement plate, and the bolts pass through the waist holes and are fixed with the nuts, and the movable range of the fixing tube is limited by the waist holes on the first cross fastener and the second cross fastener;

[0013] As a further preferred embodiment of the present invention, the first cross fastener and the second cross fastener are welded and fixed on the fixed pipe, and the first cross fastener and the second cross fastener are respectively located on the upper and lower end surfaces of the bottom placement plate or the upper placement plate;

[0014] As a further preferred embodiment of the present invention, a plurality of displacement adjustment grooves are provided on the bottom placement plate or the upper placement plate, and horizontal bars are evenly distributed in each displacement adjustment groove, and the horizontal bars are fixed to the bottom placement plate or the upper placement plate by bolts and nuts;

[0015] As a further preferred embodiment of the present invention, a waist hole is provided on the side wall of the fixing tube, and the locking assembly is a screw, a nut and an anti-skid gasket. The screw passes through the waist hole of the fixing tube and the ring at the lower end of the chassis hook and is fixed to the fixing tube through the nut and the anti-skid gasket.

[0016] As a further preferred solution of the utility model, the chassis hook moves along the displacement adjustment groove as the car shakes, and also moves along the waist hole opened in the fixing tube as the car shakes, and the chassis hook is a James-type car hook.

[0017] Compared with the prior art, the utility model has the following beneficial effects:

[0018] In the utility model, the design of the chassis hook fully considers the stability requirements during automobile transportation. Through the locking assembly, the chassis hook is firmly fixed on the fixing tube to ensure a stable connection between the automobile and the transport rack. Even if the automobile shakes during transportation, the chassis hook can move freely within a certain range by virtue of the design of the displacement adjustment slot and the waist hole of the fixing tube, thereby adapting to such shaking, effectively preventing the separation between the automobile and the transport rack, and significantly improving the stability of transportation.

[0019] The chassis hook adopts the James-style hook design. Its excellent load-bearing capacity and stable hanging effect enable it to firmly fix the car chassis and prevent the car chassis from any damage or scratches during transportation. The combination design of the displacement adjustment slot and the fixing tube gives the chassis hook a high degree of flexibility, allowing it to adjust its position according to car chassis of different sizes and shapes. At the same time, the waist hole design on the fixing tube further enhances the adaptability of the chassis hook, allowing it to move freely when the car shakes and maintain a stable connection.

[0020] The installation process of the chassis hook is simple and quick, and the introduction of the locking assembly makes installation easy. In addition, the setting of the first cross fixing piece and the second cross fixing piece greatly simplifies the installation and fixing process of the fixing pipe, and improves the overall work efficiency. The installation structure of the chassis hook not only ensures the stable connection between the car and the transport rack, but also effectively prevents the chassis hook from loosening or falling off during transportation through the setting of multiple fixing points and the restriction of the horizontal bars, providing a solid safety guarantee for the entire transportation process.

DETAILED DESCRIPTION

[0027] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0028] like Figure 1 - Figure 5 As shown, a double-layer automobile transport rack is unique in design and rich in functions, and mainly consists of the following parts: a transport vehicle body 1, a bottom placement board 2, an upper placement board 3, a protective roof 4, a side frame 5, and a lifting device 6. These components work together to ensure the stability and convenience of automobile transportation.

[0029] From bottom to top, the bottom placement board 2, the upper placement board 3 and the protective ceiling 4 are sequentially installed on the transport vehicle body 1 to form a stable frame. The side frame 5 serves as a supporting structure to tightly connect the bottom placement board 2, the upper placement board 3 and the protective ceiling 4 together to ensure the stability of the entire structure.

[0030] In particular, the tails of the bottom placement board 2 and the upper placement board 3 are equipped with two sets of lifting devices 6, and the positions of these lifting devices 6 are staggered, which provides great convenience for the entry and exit of the car. This design not only improves the transportation efficiency, but also ensures the safety of operation.

[0031] In order to further enhance the stability of the car, displacement adjustment grooves 7 are provided on the bottom placement plate 2 and the upper placement plate 3. Multiple fixing tubes 8 are inserted into the displacement adjustment grooves 7, and the positions of the fixing tubes 8 can be flexibly adjusted as needed. The upper ends of the fixing tubes 8 are provided with embedded holes 12, and the chassis hooks 11 are fixed in the embedded holes 12 through locking components 13, thereby hooking the chassis of the car to achieve safe hanging.

[0032] In order to prevent the fixing tube 8 from falling or shifting in the displacement adjustment groove 7, we specially design the first cross fastener 9 and the second cross fastener 10. The two cross fasteners are respectively sleeved on the tube wall of the fixing tube 8 and fixed to the waist holes of the bottom placement plate 2 or the upper placement plate 3 by bolts passing through the waist holes. In this way, even if the car shakes, the connection between the chassis hook 11 and the chassis can be well protected.

[0033] In addition, each displacement adjustment groove 7 has horizontal bars equidistantly distributed therein, which are fixed to the bottom placement plate 2 or the upper placement plate 3 by bolts and nuts, limiting the range of movement of the fixed tube 8 in the displacement adjustment groove 7. This design enables the fixed tube 8 to move with the shaking of the car, but at the same time will not deviate from the preset track.

[0034] We also specially open a waist hole on the side wall of the fixing tube 8 to install the locking assembly 13. The locking assembly 13 is composed of a screw, a nut and an anti-skid washer, which passes through the waist hole of the fixing tube 8 and the ring at the lower end of the chassis hook 11, and is fixed by the nut and the anti-skid washer. In this way, the chassis hook 11 can move in the displacement adjustment groove 7 and the waist hole of the fixing tube 8 with the shaking of the car without loosening or falling off.

[0035] We have selected the Zhan type coupler as the chassis coupler 11. This coupler has good stability and reliability, and can ensure the safety of the car during transportation.

[0036] This double-layer car transport rack ensures the stability and safety of car transportation through its carefully designed structure and components. At the same time, its flexibility and convenience also bring great convenience to users.

[0037] When in use: The chassis hook 11 is an indispensable part of the double-layer automobile transport rack, which is responsible for tightly connecting the automobile chassis to the transport rack. During use, the chassis hook 11 firmly hooks the automobile chassis through its unique hook-shaped design to ensure the stability of the automobile during transportation. When the automobile shakes, the chassis hook 11 can move freely in the displacement adjustment slot 7 and on the fixing pipe 8 to adapt to different amplitudes of shaking, thereby protecting the automobile from damage.

[0038] The installation process of the chassis hook 11 is simple and efficient. First, insert the corresponding number of fixing tubes 8 into the preset displacement adjustment grooves 7 on the bottom placement plate 2 and the upper placement plate 3 according to actual needs. Then, align the embedding hole 12 of the chassis hook 11 with the top of the fixing tube 8, and use the locking assembly 13 (including screws, nuts and anti-slip gaskets) to fix the chassis hook 11 to the fixing tube 8. In order to ensure the stability of the fixing tube 8, we also install the first cross fixing piece 9 and the second cross fixing piece 10 at its upper and lower ends. These two fixing pieces are connected to the reserved holes on the bottom placement plate 2 or the upper placement plate 3 by bolts and nuts, which effectively prevents the fixing tube 8 from shaking in the displacement adjustment groove 7.

[0039] In addition, we also set horizontal bars in the displacement adjustment groove 7 to further limit the range of motion of the fixed pipe 8. These horizontal bars are fixed to the bottom placement plate 2 or the upper placement plate 3 by bolts and nuts, providing a more stable support for the chassis hook 11.

[0040] The chassis hook 11 has been successfully installed on the double-layer automobile transport frame. During transportation, it can effectively connect the automobile chassis with the transport frame to ensure the stability and safety of the automobile during transportation.

[0041] The chassis hook design of this utility model emphasizes transportation stability, and the locking assembly ensures a stable connection between the car and the transport rack. The chassis hook adopts the James-style car hook design, which has a strong load-bearing capacity and stable hanging to prevent chassis damage. The displacement adjustment slot and the waist hole design of the fixed pipe give the chassis hook a high degree of flexibility to adapt to chassis of different sizes. The installation process is simple and quick, and the first and second cross fixings simplify the installation process and improve work efficiency. Multiple fixing points and horizontal bar restrictions prevent loosening and fall off, providing a solid and safe guarantee.

[0042] The above are the preferred embodiments of the utility model and the technical principles used therein. For those skilled in the art, without departing from the spirit and scope of the utility model, any obvious changes such as equivalent transformation, simple replacement, etc. based on the technical solution of the utility model shall fall within the protection scope of the utility model.
