Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of semitrailer, in particular to a semitrailer frame and a working method thereof. BACKGROUND

[0002] The semitrailer frame is an important part of the semitrailer, not only supporting the structure of the whole vehicle, but also bearing the heavy task of transporting goods. The frame is the basis of the semitrailer, and its design and manufacture directly affect the performance, safety and service life of the vehicle. The semitrailer frame is the main structure of the semitrailer, usually composed of girders, welded I-beams, support crossbeams, connecting crossbeams, side beams, lock heads, draw pin connecting devices, face plates, etc. The main function of the frame is to support and fix other components such as the carriage, suspension system, running gear, etc., to ensure the stability and safety of the vehicle during driving.

[0003] According to the search, the patent with the publication number CN217124929U discloses a semitrailer frame, which comprises an integrated traction plate and a load-bearing plate, two parallel support longitudinal beams are connected along the length direction of the load-bearing plate, the two support longitudinal beams are symmetrically arranged along the center line of the load-bearing plate, at least two parallel support crossbeams are transversely arranged between the two support longitudinal beams, the support crossbeams and the support longitudinal beams intersect and form at least two intersection points on the same support longitudinal beam, and a steel plate spring is elastically connected between each two adjacent intersection points. The support longitudinal beams can effectively collapse and absorb energy, and the support crossbeams are additionally arranged between the support longitudinal beams to further collapse and absorb energy. The steel plate spring releases the collapsed and absorbed energy by force deformation, and avoids directly impacting the frame where the load-bearing plate is located. Through the comprehensive action, the damage to the frame can be effectively avoided, and the cracks in the frame can be avoided.

[0004] However, the above-mentioned semitrailer frame still has the following optimization points. Since the load-bearing plate and the support longitudinal beam are fixedly connected, when the semitrailer suddenly brakes, the goods will rush forward due to inertia, and this impact force will directly act on the frame, which may cause the frame to deform or even break. For example, it is often reported that the driver's cab is deformed due to the forward rush of goods when the semitrailer suddenly brakes, and the frame is subjected to a large pressure. Although the inertial impact force during sudden braking is one-time, if it happens frequently, the frame material will be damaged due to repeated stress, which may not be easily detected in the short term, but long-term accumulation may cause cracks or breakage of the frame, increasing the risk of accidents. For example, the frame is usually composed of multiple steel plates welded together, and the impact force during sudden braking may cause the welded parts to bear excessive stress, resulting in cracking of the weld. This problem is particularly evident after long-term use of the vehicle, and frequent maintenance may be required. Therefore, there is an urgent need for a semitrailer frame to solve the above technical problems. SUMMARY

10. A method for assembling and unassembling a semi-trailer frame according to any one of claims 1 to 9, characterized in that: The method includes the following steps: S1, as described above, the longitudinal beam frame (1), the cross beam (2), the connecting panel (501), the bearing panel (502), the first bolt (504), the guide column (506), the slider (507), the first spring (508), the telescopic support column (509) and the second bolt (512) are assembled into a panel mechanism (5), and the longitudinal beam frame (1) can be connected to the traction seat mechanism of the traction head through the traction pin mechanism (3) during operation. In the subsequent process of fixing the carriage to the bearing panel (502) and loading the cargo for transportation, if an emergency brake occurs, multiple groups of The relative expansion and contraction of the first spring (508) causes the slider (507) to move horizontally on the guide column (506), and the connection between the telescopic support column (509) and the load-bearing panel (502) causes the load-bearing panel (502) and the connection panel (501) to move relative to each other, thereby effectively buffering the inertial impact force generated by the fully loaded carriage during sudden braking, thereby effectively preventing the large inertial impact force from damaging the connection and fixing mechanism between the carriage and the load-bearing panel (502) and the frame, and effectively preventing the large inertial impact force from damaging the cargo, thereby reducing the transportation loss of the cargo; S2, as described above, the first groove (601), the second groove (602), the second spring (603), the mounting bracket (604), the damping rod (606) and the roller (605) are assembled into a support mechanism (6), and in the subsequent process of fixing the carriage to the load-bearing panel (502) and loading the goods for transportation, the load-bearing panel (502) can be auxiliary supported by the cooperation between the roller (605), the mounting bracket (604), the second spring (603) and the damping rod (606), thereby effectively sharing the load of the telescopic support column (509) and increasing the support range of the load-bearing panel (502), making it less likely to tilt easily. The anti-tilt stability of the load-bearing panel (502) and the carriage fixed on the load-bearing panel (502) is effectively improved. At the same time, the second spring (603) can be extended and contracted in conjunction with the damping rod (606) to effectively buffer and reduce the bumps and vibrations generated during the vehicle's travel, further protecting the carriage, cargo, and frame. Moreover, when relative movement occurs between the load-bearing panel (502) and the connecting panel (501), the roller (605) can roll in the first groove (601), ensuring that the mounting frame (604), the second spring (603), and the damping rod (606) can continuously provide auxiliary support for the load-bearing panel (502). S3, as described above, the reinforcing connecting plate (701) and the connecting column (702) are assembled into a reinforcing mechanism (7), so that the longitudinal beam frame (1) and the cross beam (2) can be reinforced and connected by the reinforcing connecting plate (701) in conjunction with the connecting column (702), thereby improving the connection strength and connection stability between the longitudinal beam frame (1) and the cross beam (2), making it less likely for the connection between the longitudinal beam frame (1) and the cross beam (2) to be broken, separated, and twisted, thereby effectively extending the overall service life of the vehicle frame.
