Description

Technical Field

[0001] This utility model relates to the field of vehicle anti-sinking technology, and in particular to a load-bearing device for preventing vehicles from sinking. Background Technology

[0002] As is commonly known, a vehicle sinking-proof load-bearing device is a device laid on the ground in areas with heavy dust, loose soil, poor road conditions, and where vehicles are prone to sinking, in order to increase the contact area between the wheels and the ground to prevent wheeled equipment from sinking.

[0003] In existing technologies, most devices use large-area steel plate-like structures that are laid directly on surfaces with poor road conditions and then retracted after vehicles have passed. However, the existing devices have a simple overall structure, making them inconvenient to install, transport, and store, thus failing to meet people's needs. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of existing devices, which have a simple overall structure and are inconvenient to install, transport, and store. This invention provides a load-bearing device to prevent vehicles from sinking. The device has a foldable structure; during transport, it can be rolled into a vertical cylindrical shape (second form), reducing its space requirements and facilitating transportation and storage. When needed, it can be unfolded into its second form and laid flat on sand or soft ground. When a vehicle drives over the device, it distributes the vehicle's weight, preventing the vehicle from sinking and ensuring driving safety. Furthermore, the device has a detachable connection structure, allowing the number of sleepers to be adjusted according to actual needs, thus broadening its applicability.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] This utility model discloses a load-bearing device for preventing vehicles from getting stuck, which is applied to sandy or soft ground. It includes several sleepers and multiple connecting components for connecting adjacent sleepers. Each sleeper has a plug hole on both sides. The connecting component includes two plug plates and a connecting chain for connecting the two plug plates.

[0007] Several sleepers, under external constraints, have a first form and a second form. The first form is that all the sleepers are laid flat in a planar shape, and the second form is that all the sleepers are rolled up into a vertical cylindrical shape. All the sleepers can be controlled to be rolled up from the first form to the second form. When transporting, the device rolls them up into a vertical cylindrical shape, i.e., the second form, which reduces the space occupied by the device and facilitates transportation and storage. When needed, they are unfolded into the second form and laid flat on sand or soft ground. When a vehicle travels over the device, the device distributes the vehicle's load, thereby preventing the vehicle from sinking and ensuring driving safety.

[0008] As a further description of the above technical solution: each of the sleepers has threaded holes at both ends, and a winding and fixing component is screwed into the threaded holes. The winding and fixing component can wrap and fix the top and bottom of the sleeper when the sleeper is controlled to be wound into the second form. In this way, the sleeper as a whole can be fixed when it is wound into the second form, which is convenient for storage and transportation.

[0009] As a further description of the above technical solution: the winding and fixing assembly includes a threaded winding post and a strap, wherein the strap is fixed on the threaded winding post, and the threaded part of the threaded winding post is screwed into the threaded hole. When the sleeper is wound into the second form, the winding and fixing assembly is inserted into the innermost and outermost ends of the sleeper respectively, and then the strap on the winding and fixing assembly is tightened and fixed, thereby realizing the shape fixation of the sleeper. The operation is convenient and quick.

[0010] As a further description of the above technical solution: the connecting component is detachably installed, and a locking mechanism is provided in the plug plate. The connecting component and the sleeper are detachably snapped together by the locking mechanism. This structural design makes it possible to increase the number of sleepers by connecting the connecting component when the overall length of the device needs to be changed, thereby making the device more applicable and simple to operate.

[0011] As a further description of the above technical solution: the inner wall of the insertion hole is provided with a pin hole, the interior of the insertion plate is provided with a cavity, the locking mechanism includes a pin shaft and a connecting plate, the connecting plate is movably installed in the cavity and connected to the inner wall of the cavity through an elastic component, one end of the pin shaft is fixed to the connecting plate, and the other end extends to the outside of the insertion plate. When the connecting plate is inserted into the insertion hole, the pin shaft can be pinned into the pin hole, thereby realizing the connection between the insertion plate and the sleeper.

[0012] As a further description of the above technical solution: the locking mechanism also includes a pressing rod, one end of which is fixedly connected to the connecting plate, and the other end extends to the outside of the plug-in plate. The pressing rod is located outside the sleeper. Therefore, when it is necessary to disassemble the connecting assembly, the pressing rod is pushed directly to make the connecting plate and the pin move synchronously. When the pin is completely removed from the pin hole, the connecting assembly is disassembled.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] The device features a foldable structure. During transportation, it can be rolled up into a vertical cylindrical shape, i.e., its second form, which reduces the space occupied by the device and facilitates transportation and storage. When needed, it can be unfolded into its second form and laid flat on sand or soft ground. When a vehicle drives over the device, the device distributes the vehicle's load, thereby preventing the vehicle from sinking and ensuring driving safety. Furthermore, the device adopts a detachable connection structure, so the number of sleepers can be changed according to actual needs, thus broadening the device's applicability.

[0015] The device is designed with a focus on the structure of the gathering structure (installation of the straps) and the structure of the connecting components, making it convenient and quick to operate in practical applications, whether it needs to be retracted or the overall length needs to be changed.

[0021] The following is in conjunction with the appendix Figure 1 -Appendix Figure 4This invention further illustrates a specific embodiment of a load-bearing device for preventing vehicles from sinking. It overcomes the shortcomings of existing devices, which have simple overall structures and are inconvenient for installation, transportation, and storage. This device adopts a foldable structure, allowing it to be rolled into a vertical cylindrical shape (second form) during transportation, reducing its footprint and facilitating transport and storage. When needed, it can be unfolded into its second form and laid flat on sand or soft ground. When a vehicle travels over the device, it distributes the vehicle's weight, preventing the vehicle from sinking and ensuring driving safety. Furthermore, the device uses a detachable connection structure, allowing the number of sleepers to be adjusted according to actual needs, thus broadening its applicability. This invention, a load-bearing device for preventing vehicles from sinking, is not limited to the description in the following embodiments.

[0022] Example 1:

[0023] This embodiment provides a load-bearing device for preventing vehicles from getting stuck, such as... Figure 1 As shown, it is used on sandy or soft ground and includes several sleepers 1 and multiple connecting components 2 for connecting adjacent sleepers 1. Each sleeper 1 has a plug hole 10 on both sides. The connecting component 2 includes two plug plates 20 and a connecting chain 21 for connecting the two plug plates 20.

[0024] Several sleepers 1 have a first form and a second form under external constraints. The first form is that all sleepers 1 are laid flat in a planar shape, and the second form is that all sleepers 1 are rolled up into a vertical cylindrical shape. All sleepers 1 can be controlled to be rolled up from the first form to the second form. When transporting, the device is rolled up into a vertical cylindrical shape, i.e., the second form, which can reduce the space occupied by the device and facilitate transportation and storage. When needed, it is unfolded into the second form and laid flat on sand or soft ground. When a vehicle is driving over the device, the device distributes the vehicle's load, thereby preventing the vehicle from sinking and ensuring driving safety.

[0025] Specifically, such as Figures 1-2 As shown, in order to facilitate storage when the sleeper 1 is controlled to be rolled up into the second form, in this embodiment, each sleeper 1 has threaded holes 11 at both ends, and a winding and fixing component 3 is screwed into the threaded holes 11. The winding and fixing component 3 can wrap and fix the top and bottom of the sleeper 1 when it is controlled to be rolled up into the second form. In this way, when the sleeper 1 is rolled up into the second form, the entire sleeper 1 can be fixed, which is convenient for storage and transportation.

[0026] Specifically, such as Figures 1-4As shown, in order to achieve the winding and fixing of the sleeper 1, in this embodiment, the winding and fixing component 3 includes a threaded winding post 30 and a strap 31. The strap 31 is fixed on the threaded winding post 30, and the threaded part of the threaded winding post 30 is screwed into the threaded hole 11. When the sleeper 1 is wound into the second form, the winding and fixing component 3 is inserted into the innermost and outermost ends of the sleeper 1 respectively, and then the strap 31 on the winding and fixing component 3 is tightened and fixed, so that the form of the sleeper 1 can be fixed. The operation is convenient and quick.

[0027] Example 2

[0028] Based on Example 1, such as Figures 1-4 As shown, in order to adjust the overall length of the device according to actual needs, in this embodiment, the connecting component 2 is detachably installed, and the plug plate 20 is provided with a locking mechanism 22. The connecting component 2 and the sleeper 1 are detachably snapped together by the locking mechanism 22. This structural setting makes it possible to increase the number of sleepers 1 by connecting the connecting component 2 when the overall length of the device needs to be changed, thereby making the device more applicable and simple to operate.

[0029] Specifically, such as Figures 1-4 As shown, in order to achieve a detachable connection of the connecting component 2, in this embodiment, the inner wall of the insertion hole 10 is provided with a pin hole 12, the inside of the insertion plate 20 is provided with a cavity 200, and the locking mechanism 22 includes a pin 223 and a connecting plate 222. The connecting plate 222 is movably installed in the cavity 200 and is connected to the inner wall of the cavity 200 through an elastic member 220. One end of the pin 223 is fixed to the connecting plate 222, and the other end extends to the outside of the insertion plate 20. When the connecting plate 222 is inserted into the insertion hole 10, the pin 223 can be pinned into the pin hole 12, thereby realizing the connection between the insertion plate 20 and the sleeper 1.

[0030] Specifically, such as Figures 1-4 As shown, in order to control the pin 223 and make the connecting assembly 2 detachable, in this embodiment, the locking mechanism 22 also includes a pressing rod 221. One end of the pressing rod 221 is fixedly connected to the connecting plate 222, and the other end extends to the outside of the plug plate 20. The pressing rod 221 is located outside the sleeper 1. Therefore, when it is necessary to disassemble the connecting assembly 2, the pressing rod 221 is pushed directly to make the connecting plate 222 and the pin 223 move synchronously. When the pin 223 is completely removed from the pin hole 12, the connecting assembly 2 is disassembled.
