[0002] With the improvement of people's living standards, private cars are becoming increasingly common, and automobile import and export trade is growing daily. Containerized multimodal transport is currently the most widely used mode of transport globally, effectively achieving the goals of cost reduction, energy conservation and emission reduction, and improved time efficiency. To maximize the use of the container space, many vehicle transport racks generally include a liftable upper platform. When loading vehicles onto the upper platform, the platform is lowered to its lowest position, and the car is moved onto and secured using the walkway structures on both sides of the upper platform. Finally, the upper platform is raised. After being raised to a certain angle, the lower platform can also be used to place vehicles.

[0003] Currently, most truck carrier platforms on the market are raised using forklifts. However, in certain scenarios where forklifts are unavailable, it is impossible to raise the upper platform. Therefore, a new type of truck carrier needs to be developed. A search revealed no identical technical solutions to this invention. Utility Model Content

[0021] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0022] like Figures 1 to 4 As shown in the figure, this utility model embodiment provides a novel vehicle transport frame, the overall structure of which includes a base frame 100, a second-layer frame 200, a monkey climbing pole jack, a hinge shaft, a synchronous linkage structure, and related connecting components; the following describes in detail the structure, connection relationship, working principle and advantages of each component.

[0023] The base frame 100 is a rectangular frame structure welded from high-strength steel, with symmetrical hinge seats and guide rails on both sides. The second-layer frame 200 is arranged parallel to the base frame 100, with one end being a fixed end connected to the hinge seats of the base frame 100 via hinge shafts on both sides, forming a hinged structure that can rotate around the shaft; the other end is a lifting end, with reinforcing ribs distributed in a grid pattern welded to its bottom to enhance load-bearing capacity. A self-lubricating bearing is installed between the hinge shaft and the hinge seat. The outer ring of the self-lubricating bearing is fixed inside the hinge seat, and the inner ring is interference-fitted with the hinge shaft, significantly reducing frictional resistance and extending service life.

[0024] After the connecting pin 306 is inserted into the socket 305, the anti-disengagement spring 501 is embedded in the annular groove on the outside of the socket 305 to form an axial mechanical lock, preventing the connecting pin 306 from loosening due to vibration during transportation and improving structural reliability.

[0025] The self-lubricating bearing between the hinge shaft and the hinge seat does not require external lubrication. The internal lubricating material continuously reduces friction, lowers the maintenance frequency, and ensures that the second-layer frame rotates 200 flexibly.

[0026] The grid-like reinforcing ribs at the bottom of the lifting end are staggered from the insertion holes 305 of the connecting plate 304, which not only improves the load-bearing strength of the second-layer frame 200, but also avoids interference with the connecting structure, ensuring uniform force distribution.

[0027] The monkey-climbing pole jacks are symmetrically arranged on both sides of the base frame 100. Each jack includes a fixed base 301, a support rod 302, and a lifting mechanism 303. The fixed base 301 is welded to the two edges of the base frame 100. The bottom of the support rod 302 is connected to the fixed base 301 through a hinge shaft and can swing with the extension and retraction of the lifting mechanism 303. The lifting mechanism 303 is a manually driven scissor-type lifting arm, composed of multiple sets of cross-hinged connecting rods. The ends of the connecting rods are equipped with rollers, which slide within the guide rails of the base frame 100 to ensure smooth lifting and controllable trajectory. A connecting plate 304 is fixed to the inner side of the lifting mechanism 303. Two insertion holes 305 are opened on the connecting plate 304. A connecting pin 306 is vertically welded to the side of the lifting end of the second-layer frame 200. The connecting pin 306 is inserted into the insertion hole 305 and locked by the anti-dislodgement spring 501 at the end to prevent vibration from causing it to fall off, forming a rigid linkage.

[0028] The working principle of the above structure is as follows: When the operator manually presses down or lifts the lever handle, it drives the connecting rod of the scissor-type lifting arm to extend or retract. Through the rollers sliding along the guide rail, it drives the support rod 302 to swing around the hinge point of the fixed seat 301, thereby pushing the connecting plate 304 and the lifting end of the second-tier frame 200 to move vertically. The scissor-type structure provides a larger lifting stroke and stability, while the guide rail restricts the movement trajectory to prevent deviation. When one side of the lever handle is activated, the pull rod transmits the pulling force to the other side lever handle through the positioning ring 401, forcing the jacks on both sides to move synchronously. The cooperation between the elastic locking pin and the positioning hole allows for quick adjustment of the pull rod length, ensuring consistent lifting amplitude on both sides at different heights and preventing the second-tier frame 200 from tilting.

[0029] The monkey-climbing jacks on both sides of the second-level frame 200 achieve synchronous lifting and lowering through a synchronous linkage structure. The synchronous linkage structure includes a positioning ring 401 fixed to the lever handle and a telescopic tension rod 402 connecting the positioning rings 401 on both sides. The tension rod consists of an inner sleeve and an outer sleeve. The surface of the inner sleeve has equally spaced positioning holes, and the outer sleeve is equipped with an elastic locking pin. The length of the tension rod can be adjusted by inserting it into the positioning holes at different positions to meet different lifting height requirements.

[0030] The working principle of this technical solution is as follows: During operation, the worker simultaneously presses down the lever handles on both sides, driving the lifting mechanism 303 of the two monkey-climbing jacks to unfold synchronously through the synchronous linkage structure, pushing the lifting end of the second-level frame 200 vertically to the target height. During this process, the stability of the scissor-type lifting arm and the guiding effect of the guide rail ensure smooth lifting; the self-lubricating bearing reduces the resistance at the hinge point, making operation more effortless; the reinforcing ribs and rigid connection design ensure structural strength, allowing it to bear heavy vehicles or cargo; when it is necessary to lower the second-level frame 200, the lever handles are operated in the opposite direction, the lifting mechanism 303 retracts, and the tension rod retracts synchronously, driving the lifting end to descend smoothly to the initial position. Throughout the process, the design of the anti-detachment spring 501 and the adjustable tension rod significantly improves safety and adaptability, especially suitable for operating environments with limited space inside containers.

[0031] The advantages of this technical solution are: high synchronous lifting accuracy: through the rigid linkage and length adjustment function of the tension rod, the jacks on both sides move synchronously, avoiding the risk of uneven load; stable and durable structure: the scissor lift arm is designed with guide rails, self-lubricating bearings, and reinforcing ribs to improve mechanical strength and service life; convenient and safe operation: manual drive eliminates reliance on external power, and detailed designs such as anti-detachment spring 501 and elastic locking pins ensure operational safety; strong adaptability: the adjustable tension rod and modular structure make it easy to adapt to containers of different sizes and load requirements.

[0032] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made using the content of this utility model specification, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
