[0026] The exemplary embodiments will now be described more fully with reference to the accompanying drawings. However, the exemplary embodiments can be implemented in various forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that this invention will be thorough and complete, and will fully convey the concept of the exemplary embodiments to those skilled in the art. Like reference numerals in the figures denote like or similar structures, and thus their detailed description will be omitted.

[0027] See Figures 1 to 5 , an embodiment of the present invention discloses a lifting device 10 for lifting the front part of a vehicle 60 for rescue when the vehicle 60 breaks down. This lifting device 10 is installed on the towing arm 50 of a trailer and can lift the front end of the vehicle 60 off the ground, so that the trailer can tow away the vehicle 60.

[0028] The lifting device according to the embodiment of the present invention includes a main beam 1, at least two lifting parts 2 and a connecting part. Among them, the lifting part 2 and the connecting part are both connected to the main beam 1. The lifting part 2 is used for lifting the vehicle, and the connecting part is used for connecting with the towing arm 50 of the trailer so that the towing arm 50 can lift the vehicle 60. In this embodiment, the main beam 1 is made of a pipe fitting. More specifically, the main beam 1 is a square pipe, the outer dimension of its cross-section is (90 - 130) mm × (100 - 140) mm, and / or the thickness is 3 - 8 mm, and / or the length is 900 - 1500 mm, and the material is Q345C. Those skilled in the art should understand that the main beam 1 can also be other structures such as a casting, or be manufactured using an I-beam, etc., and is not limited to a pipe fitting. Preferably, the outer dimension of the cross-section of the main beam 1 is 110 mm × 120 mm, the thickness is 5 mm, and the length is 1200 mm. The main beam 1 of this size can adapt to most vehicle models and has a wide application range.

[0029] In a preferred embodiment, it includes two lifting parts 2. The two lifting parts 2 are arranged at intervals on the main beam 1, and the lifting part 2 has a connecting part 3 for combining with the front part of the vehicle 60.

[0030] The lifting part 2 can be directly fixed on the main beam 1. In a preferred embodiment, the lifting part 2 is movably arranged on the main beam 1, and a fastener is arranged between the lifting part 2 and the main beam 1. In this way, the position of the lifting part 2 on the main beam 1 can be adjusted, so as to adapt to different vehicles.

[0031] See Figures 1 to 3, the lifting part 2 includes a sliding part 21 and a lifting part 22. The sliding part 21 is slidably connected to the main beam 1, and the lifting part 22 is disposed on the sliding part 21 in a liftable manner. The implementation form of the sliding connection relationship between the sliding part 21 and the main beam 1 is not limited. In this embodiment, the sliding part 21 has a frame structure sleeved on the main beam 1 made of a pipe fitting. The sliding connection between the sliding part 21 and the main beam 1 can also be achieved by providing structures such as mutually cooperating dovetail grooves and slide rails. The lifting method of the lifting part 22 is not limited either. In this embodiment, the lower end of the lifting part 22 is a threaded rod, and a threaded hole cooperating with the threaded rod is provided on the sliding part 21. The diameter specifications of the threaded hole and the threaded rod can be M50. By rotating the lifting part 22, the lifting and lowering of the lifting part 22 can be achieved. In addition, the lifting and lowering can also be achieved by adding or reducing cushion blocks below the lifting part 22. The top of the lifting part 22 is provided with the engaging part 3, and the structure of the engaging part 3 is a groove structure so as to be able to engage with the lifting beam (see the relevant description later) under the vehicle 60 and lift the vehicle 60.

[0032] As Figure 1 shown, a plurality of position adjustment holes 11 are provided on the main beam 1, and fixing holes corresponding to a part of these position adjustment holes 11 are provided on the sliding part 21. The sliding part 21 can be connected to at least one of the position adjustment holes 11 through a fastener, so as to achieve the purpose of adjusting the position of the lifting part 2 and fixing the lifting part 2 on the main beam 1. The position adjustment holes 11 are located at positions on the main beam 1 close to both ends. The position adjustment holes 11 close to each end form a group, and the number of each group is about 10, with a diameter of 10 - 20 mm, preferably 15 mm.

[0033] When the lifting device according to the embodiment of the present invention is in use, it is first connected to the towing arm 50 of the trailer, and then inserted under the front end of the vehicle 60. After being combined with the vehicle 60 by using the engaging part 3, the vehicle 60 is lifted by using the towing arm 50, and then the vehicle 60 can be towed away. It should be noted that the vehicle mentioned in the present invention refers to a vehicle that needs to be towed for rescue after breaking down, such as a passenger car carrying multiple people, etc., and does not include vehicles such as bicycles, motorcycles, and electric bicycles that do not require towing for rescue.

[0034] This lifting device is directly connected to the towing arm of the trailer, without the need to weld a towing hook or other structures on the vehicle to be rescued, reducing the weight of the whole vehicle, reducing the energy consumption of the vehicle, and avoiding the interference between the towing hook and the front end of the vehicle during towing, avoiding the risk of vehicle damage. When lifting, the front wheels of the vehicle can be lifted off the ground, which also improves the passing performance of the vehicle. In addition, by adjusting the position of the lifting part and the height of the lifting part, the versatility can be enhanced, and all the operating vehicles of the enterprise can be satisfied.

[0035] An embodiment of the present invention also discloses a vehicle lifting system, which includes a trailer with a lifting arm and also includes the lifting device of this embodiment. When in use, the vehicle lifting system can be provided with a lifting beam at the front of the vehicle that can cooperate with the lifting part, further improving the safety of the vehicle during lifting and enabling the lifting part to be more reliably combined with the vehicle.

[0036] The exemplary embodiments of the present invention have been specifically shown and described above. It should be understood that the present invention is not limited to the disclosed embodiments. On the contrary, the present invention is intended to cover various modifications and equivalent arrangements included within the spirit and scope of the appended claims.
