[0033] Second Embodiment
[0034] Please refer to Figure 6 Based on the rear-dumping semi-trailer with good stability provided in the first embodiment of this application, the second embodiment of this application proposes another rear-dumping semi-trailer with good stability. The second embodiment is only the preferred way of the first embodiment, and the implementation of the second embodiment will not affect the independent implementation of the first embodiment.
[0035] Specifically, the difference of the rear-dumping semi-trailer with good stability provided in the second embodiment of this application is that a cross beam 35 is fixedly connected to the frame 1, a lifting frame 36 is fixedly connected to the right side of the frame 1, a force-bearing rod one 37 is fixedly connected to the lifting frame 36, a force-bearing beam 38 is fixedly connected to the bottom of the frame 1, and a force-bearing rod two 39 is fixedly connected to the force-bearing beam 38. When blanking, since most of the pressure in the carriage acts on the rear part of the frame 1 during rear-dumping, the rear half of the frame 1 is lifted, and a part of the pressure is transferred to the force-bearing beam 38 and the front part of the frame 1 by using the force-bearing rod one 37 and the force-bearing rod two 39, reducing the risk of flatness and fracture of the rear part of the frame 1.
[0036] Compared with the related technology, the rear-dumping semi-trailer with good stability provided by the utility model has the following beneficial effects:
[0037] The semi-trailer frame 1 transfers part of the rear force to the front part and the force-bearing beam 38, avoiding stress concentration at the rear of the frame 1, making the force on the entire frame 1 more uniform, greatly enhancing the structural stability of the semi-trailer; reducing stress fatigue at the rear of the frame 1 caused by excessive force, reducing the risk of deformation and fracture of the frame 1, and extending the service life of the semi-trailer.
[0038] The above are only the embodiments of the present invention, and do not limit the patent scope of the present invention accordingly. Any equivalent structure or equivalent process transformation made by using the content of the specification and drawings of the present invention, or directly or indirectly applied to other related technical fields, shall be similarly included in the patent protection scope of the present invention.
