Description

Technical Field

[0001] This utility model relates to the field of lifting equipment technology, and in particular to a car carrier lifting structure. Background Technology

[0002] The lifting structure of a car carrier is an important component of the car carrier, enabling the upper loading platform to be lifted up and down, thus facilitating loading and unloading.

[0003] Current car carrier lifting structures have limitations. They are not easy to raise and lower the upper platform significantly, and the height adjustment of the upper platform is not flexible enough, making it difficult to make full use of the space resources of the semi-trailer. In addition, existing car carrier lifting structures lack safety and stability during transportation, thus affecting the overall carrying capacity and service life of the car carrier.

[0004] Therefore, it is essential to provide a car carrier lifting structure to address the shortcomings of existing technologies. Utility Model Content

[0005] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a car carrier lifting structure, including a car carrier lower frame body, adjustable front support components and adjustable rear support components installed on both the left and right sides of the car carrier lower frame body, an upper platform installed on the adjustable front support components and adjustable rear support components, and a loading auxiliary component installed at the rear of the upper platform.

[0006] The above-mentioned objectives of this utility model are achieved through the following technical means.

[0007] A car carrier lifting structure is provided, including a car carrier lower frame body. Adjustable front support components and adjustable rear support components are installed on both the left and right sides of the car carrier lower frame body. An upper platform is installed on the adjustable front support components and the adjustable rear support components, and a loading auxiliary component is installed at the rear of the upper platform.

[0008] Specifically, the adjustable rear support assembly includes a rear lifting cylinder, the bottom of which is fixed to the lower frame of the car carrier, the top of which is installed at the bottom of the upper platform, an upper swing arm is hinged to the bottom of the upper platform, a lower swing arm is hinged to the bottom of the upper swing arm, the lower swing arm has an arched structure, a positioning element A is installed between the upper and lower swing arms, and a positioning support assembly is installed on one side of the lower swing arm.

[0009] Preferably, the bottom of the positioning support assembly and the lower swing arm are respectively hinged to the upper part of the car carrier's lower frame body to form a triangular structure. A positioning element B is installed at the hinge point between the bottom of the telescopic sleeve and the lower frame body of the car carrier. The positioning support assembly includes a telescopic sleeve, the two ends of which are respectively hinged to the upper part of the lower frame body of the car carrier and the bottom of the upper swing arm. Several circular through holes are equally spaced on the telescopic sleeve, and a positioning pin is horizontally engaged between two circular through holes.

[0010] The adjustable front support assembly includes a front column, the bottom of which is fixedly installed above the car carrier's lower frame. A front lifting cylinder is installed at the top of the front column, and a movable pulley is installed below the front lifting cylinder. A steel wire rope is slidably connected to the movable pulley, and a fixed pulley is slidably connected to the steel wire rope. The fixed pulley is installed at the top of the front column. One end of the steel wire rope is fixedly installed on the inside of the front column, and the other end of the steel wire rope is connected to a slider. The slider is slidably connected to a slide rail, which is located inside the front column. The slider is fixedly installed on the side of the upper platform.

[0011] A telescopic rod is installed on the lower end of the upper platform. The bottom end of the telescopic rod is installed above the car carrier's lower frame body. A positioning buffer platform is installed above the car carrier's lower frame body. The positioning buffer platform is movably connected to the lower part of the upper platform.

[0012] The loading auxiliary components include a ramp support plate, on both sides of which slide grooves are engaged. The two grooves are symmetrically opened on the inner side of the rear end of the upper platform, which has a ramp-shaped structure at the rear end.

[0013] This invention enables a significant lifting and lowering of the upper platform through an adjustable front support assembly in conjunction with an adjustable rear support assembly. This allows the upper platform to be raised to a certain height when needed to accommodate loading requirements at different heights, further maximizing the use of the semi-trailer's space resources. At the same time, when the upper platform is lowered to its lowest position, it ensures close proximity to the car carrier's undercarriage, facilitating loading and unloading while guaranteeing safety and stability during transportation. This, in turn, improves the overall carrying capacity and service life of the car carrier. Attached Figure Description

[0044] The present invention will be further described in conjunction with the following embodiments.

[0045] Example 1.

[0046] like Figure 1-3 As shown, a car carrier lifting structure includes a car carrier lower frame body 1, adjustable front support assembly 2 and adjustable rear support assembly 3 are installed on both the left and right sides of the car carrier lower frame body 1, an upper platform 4 is installed on the adjustable front support assembly 2 and the adjustable rear support assembly 3, and a loading auxiliary assembly 5 is installed at the rear of the upper platform 4.

[0047] By using the adjustable front support assembly 2 in conjunction with the adjustable rear support assembly 3, the upper platform 4 can be raised and lowered significantly, and the height of the upper platform 4 can be flexibly adjusted, further making full use of the space resources of the semi-trailer, while ensuring safety and stability during transportation, thereby improving the overall carrying capacity and service life of the car carrier.

[0048] Because the height of the upper platform 4 is adjustable, this semi-trailer can transport a variety of different types of goods. When the upper platform 4 is raised, it can load taller vehicles or other heavy goods. When the upper platform 4 is lowered to the ground, it can load one standard 40-foot container or two 20-foot containers, greatly expanding the transportation range.

[0049] like Figure 1-3 As shown, the adjustable rear support assembly 3 includes a rear lifting cylinder 6. The bottom of the rear lifting cylinder 6 is fixed on the car carrier's lower frame body 1. The top of the lifting cylinder is installed on the bottom of the upper platform 4. An upper swing arm 7 is hinged to the bottom of the upper platform 4. A lower swing arm 8 is hinged to the bottom of the upper swing arm 7. The lower swing arm 8 has an arched structure. A positioning element A 9 is installed between the upper swing arm 7 and the lower swing arm 8 to position the opening and closing angle of the upper swing arm 7 and the lower swing arm 8. A positioning support assembly 10 is installed on one side of the lower swing arm 8.

[0050] like Figure 1-3 As shown, the bottom of the positioning support assembly 10 and the lower swing arm 8 are respectively hinged to the upper part of the car carrier's lower frame body 1 to form a triangular structure. The bottom of the telescopic sleeve 12 is fitted with a positioning element B11 at the hinge point between it and the car carrier's lower frame body 1 to position the rotation angle of the telescopic sleeve 12. The positioning support assembly 10 includes the telescopic sleeve 12, the two ends of which are respectively hinged to the upper part of the car carrier's lower frame body 1 and the bottom of the upper swing arm 7. Several circular through holes 13 are equidistantly opened on the telescopic sleeve 12, and a positioning pin 14 is horizontally engaged between two circular through holes 13.

[0051] The triangular structure formed by the positioning support component 10, the lower swing arm 8, and the car carrier underframe body 1 can improve safety and stability. The positioning support component 10, which can be adjusted in rotation angle and length, can stably support and position the hinge of the upper swing arm 7 and the lower swing arm 8. It supports and positions the upper swing arm 7 and the lower swing arm 8 with different opening and closing angles. The upper swing arm 7 and the lower swing arm 8 with different opening and closing angles, together with the vertically telescopic rear lifting cylinder 6, can achieve the purpose of stably adjusting the height of the upper platform 4.

[0052] The adjustable front support assembly 2 and the adjustable rear support assembly 3 work together to achieve a large lifting height of the upper platform 4, so that the upper platform 4 can be raised to a certain height when needed to adapt to different loading requirements. At the same time, when the upper platform 4 is lowered to its lowest position, it can ensure that it is close to the car carrier's lower frame body 1, which facilitates loading and unloading.

[0053] like Figure 1-3 As shown, the adjustable front support assembly 2 includes a front column 15. The bottom of the front column 15 is fixedly installed above the car carrier's lower frame body 1. A front lifting cylinder 16 is installed at the top of the front column 15. A movable pulley 17 is installed below the front lifting cylinder 16. A steel wire rope 18 is slidably connected to the movable pulley 17. A fixed pulley 19 is slidably connected to the steel wire rope 18. The fixed pulley 19 is installed at the top of the front column 15. One end of the steel wire rope 18 is fixedly installed on the inner side of the front column 15. The other end of the steel wire rope 18 is connected to a slider 20. The slider 20 is slidably connected to a slide rail 21. The slide rail 21 is opened inside the front column 15. The slider 20 is fixedly installed on the side of the upper platform 4.

[0054] The extension of the current lifting cylinder 16 can drive the movable pulley 17 to move downwards. The downward-moving movable pulley 17 drives one end of the wire rope 18 to lift the slider 20. The slide rail 21 provides vertical guidance for the rising slider 20, thereby the slider 20 drives the upper platform 4 to rise. Similarly, the front lifting cylinder 16 retracts and descends.

[0055] like Figure 1-3 As shown, a telescopic rod 22 is installed on the lower middle surface of the upper platform 4, and its extension and retraction are electrically controlled. The bottom end of the telescopic rod 22 is installed above the car carrier underframe body 1 to support the middle of the upper platform 4 and ensure the stability of the upper platform 4. A positioning buffer platform 23 is installed above the car carrier underframe body 1. The positioning buffer platform 23 is movably connected to the lower part of the upper platform 4. The positioning buffer platform 23 can ensure that the upper platform 4 is close to the car carrier underframe body 1 when it is lowered to its lowest position, while playing the role of shock absorption, buffering and positioning.

[0056] like Figure 1-3As shown, the loading auxiliary component 5 includes a ramp support plate 24. The ramp support plate 24 has sliding grooves 25 on both sides. The two grooves 25 are symmetrically opened on the inner side of the tail end of the upper platform 4, so that the ramp support plate 24 slides on the tail end of the upper platform 4 which has a ramp structure. By placing the ramp support plate 24 on the ground, it is convenient to load the vehicle.

[0057] This utility model includes a car carrier underframe body 1. Adjustable front support components 2 and adjustable rear support components 3 are installed on both the left and right sides of the car carrier underframe body 1. An upper platform 4 is installed on the adjustable front support components 2 and the adjustable rear support components 3. A loading auxiliary component 5 is installed at the rear of the upper platform 4. By using the adjustable front support components 2 in conjunction with the adjustable rear support components 3, the upper platform 4 can be raised and lowered significantly. The height of the upper platform 4 can be flexibly adjusted, further making full use of the space resources of the semi-trailer. At the same time, it ensures safety and stability during transportation, thereby improving the overall carrying capacity and service life of the car carrier.

[0058] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit the scope of protection of this utility model. Although this utility model 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 this utility model without departing from the essence and scope of the technical solutions of this utility model.
