In order to ensure the safety and smoothness of road traffic, the use of tow trucks is a very important part. Existing tow trucks generally include a flatbed frame and a lifting device on the frame, which can lift the faulty vehicle or obstacle and move it to a safe area. However, the existing flatbed devices of tow trucks are often large in size and cannot handle two vehicles at the same time, which limits their scope of application and efficiency. Utility Model Content

[0003] The utility model provides a hidden double-layer integrated flatbed tow truck, the upper flatbed and the lower flatbed of which can carry a car respectively, and reduce the overall height and length of the vehicle when fully loaded, thereby meeting the requirements of the new standard. At the same time, the structure is simple and reliable, and can realize free switching between single-layer and double-layer, adapt to different working scenes, and improve work efficiency.

[0004] In order to achieve the above-mentioned purpose, the utility model provides the following technical solutions: a hidden double-layer integrated flatbed tow truck, comprising: a lower flatbed, which is matched on the carrier through a flip slide, and the front end of the lower flatbed is provided with a front guard frame, and the tail is hinged with a rear support plate; an upper flatbed, the front end of the upper flatbed is hinged with the front guard frame, and a lifting cylinder is hinged between the two sides of the middle part of the upper flatbed and the lower flatbed; the lifting cylinder is connected to the hydraulic control system of the carrier.

[0005] Preferably, a storage groove is provided on the top of the lower flat plate corresponding to the upper flat plate, and when the upper flat plate is flipped down, it is located in the storage groove.

[0006] Preferably, the front end of the upper flat plate is an upwardly inclined lifting slope, and is hinged to the middle part of the front guard frame through the front end of the lifting slope; a stop slope is provided at the top of the lifting slope.

[0007] Preferably, it also includes a safety strut, which is composed of a nested outer cylinder and an inner core, and the inner core is hinged to the middle part of the lower flat plate, the top of the outer cylinder is provided with a connecting hole that penetrates radially, and the two sides of the tail of the upper flat plate are respectively provided with pin holes, and each of the pin holes is matched with a pin shaft; the inner core and the outer cylinder are respectively provided with a plurality of transversely penetrating adjustment holes arranged along the length direction, and an adjustment pin penetrating the adjustment hole.

[0008] Preferably, guard plates are respectively provided on both sides of the top of the lower flat plate corresponding to the front guard frame, and the front end of the upper flat plate is located inside the two guard plates.

[0009] The beneficial effect of the utility model is that the upper plate and the lower plate can carry a car respectively. In the actual operation process, the staff uses the hydraulic system of the vehicle to drop the upper plate to fit the lower plate, and then uses the flip slide to slide the lower plate backward as a whole, and makes the rear support plate touch the ground. At this time, the first car can be moved to the top of the upper plate through the rear support plate and the lower plate. After the vehicle is fixed, the staff operates the lifting cylinder through the hydraulic system to flip the rear part of the upper plate upward, thereby freeing up the carrying space of the lower plate. After that, the second car is smoothly moved to the lower plate through the rear support. Finally, the staff continues to operate the hydraulic system to make the flip slide reset the lower plate as a whole to complete the loading operation of the two cars. In the unloading operation, its operation sequence is opposite to that of the loading operation. In addition, in the actual operation process, the lifting cylinder and the flip slide can work simultaneously through the hydraulic system, so that the loading and unloading operation of the lower plate does not affect the upper plate. The structure also reduces the overall height and length of the vehicle when fully loaded, thus meeting the requirements of the new standard. At the same time, the structure is simple and reliable, and can realize the free switching between single-layer and double-layer, adapting to different working scenes and improving work efficiency. When the upper flatbed is loading the vehicle, the lifting slope lifts the front wheel of the vehicle, so that the front of the vehicle is tilted up, avoiding the problem of excessive tilting of the rear of the vehicle after the tail of the upper flatbed is flipped and lifted. In addition, it is convenient to make a larger accommodation space for the front of the vehicle loaded on the lower flatbed. The stop slope is used to block the front wheels of the upper flatbed vehicle to prevent it from rushing out of the upper flatbed. When the upper flatbed is lifted into place, a support structure is formed between the tail of the upper flatbed and the middle of the lower flatbed through the safety support rod, thereby ensuring the stability and safety of the upper flatbed. During operation, when the tail of the upper flatbed is lifted to an appropriate height, the staff aligns the connection hole at the top of the outer cylinder with the pin hole and connects them through the pin shaft, and then locks the length of the safety support rod by adjusting the pin and the adjustment hole. The front guard frame is reinforced by a guard plate, and a containment structure is formed for the front end of the upper flat plate, thereby providing lateral protection for the upper vehicle.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0016] according to Figure 1 , Figure 2 , Figure 3 As shown, a hidden double-layer integrated flatbed tow truck comprises: a lower flatbed 1, which is matched on the carrier through a flip slide, and the front end of the lower flatbed 1 is provided with a front guard frame 2, and the tail is hinged with a rear support plate 3; an upper flatbed 4, the front end of the upper flatbed 4 is hinged to the front guard frame 2, and the two sides of the middle part of the upper flatbed 4 are hinged with a lifting cylinder 5 between the lower flatbed 1; the lifting cylinder 5 is connected to the hydraulic control system of the carrier.

[0017] Through the above arrangement, the upper plate 4 and the lower plate 1 can carry a car respectively. In the actual operation process, the staff uses the hydraulic system of the vehicle to lower the upper plate 4 to fit with the lower plate 1, and then uses the flip slide of the vehicle to slide the lower plate 1 backward as a whole, and make the rear support plate 3 touch the ground. At this time, the first car can be moved to the top of the upper plate 4 through the rear support plate 3 and the lower plate 1. After the vehicle is fixed, the staff operates the lifting cylinder 5 through the hydraulic system to flip the rear part of the upper plate 4 upward, thereby freeing up the carrying space of the lower plate 1. After that, the second car is smoothly moved to the lower plate 1 through the rear support. Finally, the staff continues to operate the hydraulic system to make the flip slide reset the lower plate 1 as a whole to complete the loading operation of the two cars. In the unloading operation, its operation sequence is opposite to that of the loading operation. In addition, in the actual operation process, the lifting cylinder 5 and the flip slide can work simultaneously through the hydraulic system, so that the loading and unloading operation of the lower plate 1 does not affect the upper plate 4. This structure also reduces the overall height and length of the vehicle when fully loaded, thus meeting the requirements of the new standard. At the same time, the structure is simple and reliable, and can achieve free switching between single and double layers, adapting to different work scenarios and improving work efficiency.

[0018] In addition, a receiving groove 6 is provided on the top of the lower plate 1 corresponding to the upper plate 4, and when the upper plate 4 is turned down, it is located in the receiving groove 6. Therefore, the vehicle on the upper plate 4 is more stable and smooth during loading and unloading.

[0019] The front end of the upper plate 4 is an upwardly inclined lifting slope 7, and is hinged to the middle part of the front guard frame 2 through the front end of the lifting slope 7; a stop slope 8 is provided on the top of the lifting slope 7.

[0020] Through the above arrangement, when the upper flat plate 4 is loaded with a vehicle, the lifting slope 7 lifts the front wheels of the vehicle so that the front of the vehicle is tilted up, thereby avoiding the problem of excessive tilting of the rear of the vehicle after the rear of the upper flat plate 4 is turned over and lifted. In addition, it is convenient to free up a larger accommodation space for the front of the vehicle loaded on the lower flat plate 1. The stop slope 8 is used to block the front wheels of the vehicle on the upper flat plate 4 to prevent it from rushing out of the upper flat plate 4.

[0021] It also includes a safety strut, which is composed of a nested outer cylinder 10 and an inner core 11, and the inner core 11 is hinged to the middle of the lower plate 1, and a connecting hole 12 is provided at the top of the outer cylinder 10 and penetrates radially, and pin holes 13 are provided on both sides of the tail of the upper plate 4, and each pin hole 13 is matched with a pin shaft 14; the inner core 11 and the outer cylinder 10 are respectively arranged along the length direction with a plurality of transverse penetrating adjustment holes 15, and an adjustment pin 16 penetrating the adjustment hole 15.

[0022] Through the above arrangement, when the upper plate 4 is lifted into place, a support structure is formed between the tail of the upper plate 4 and the middle of the lower plate 1 through the safety strut, thereby ensuring the stability and safety of the upper plate 4. During operation, when the tail of the upper plate 4 is lifted to an appropriate height, the staff aligns the connecting hole 12 at the top of the outer cylinder 10 with the pin hole 13, and connects them through the pin shaft 14, and then locks the length of the safety strut by adjusting the pin 16 and the adjusting hole 15.

[0023] Guard plates 17 are respectively provided on both sides of the top of the lower plate 1 corresponding to the front guard frame 2 , and the front end of the upper plate 4 is located inside the two guard plates 17 .

[0024] Through the above arrangement, the front guard frame 2 is reinforced by the guard plate 17, and a containment structure is formed for the front end of the upper plate 4, thereby providing lateral protection for the upper vehicle.

[0025] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
