Description

Technical Field

[0001] The utility model relates to the field of side-dumping semi-trailers, in particular to a vehicle frame with an integrally formed flip fixing seat and a side-dumping semi-trailer. Background Art

[0002] At present, for side-unloading semi-trailers in the market, the flip fixing seat is mostly a split structure, that is, the left and right flip plates are directly welded through the flip pin. The flip plate generally adopts a flat structure, which results in the diagonal support under the flip seat cannot be reinforced to the bottom of the flip point. The stress generated by the flipping of the goods can only be supported by the strength of the flip plate. Therefore, the flip plate meets the strength requirements by sacrificing its own weight, and the welding part between the flip plate and the through-square tube is also prone to tearing.

[0003] The utility model patent with the authorization announcement number CN221188850U discloses an integrated flip fixing plate structure and flip fixing structure of a side-unloading semi-trailer, including a first flip fixing plate, a second flip fixing plate and a connecting plate; the first flip fixing plate and the second flip fixing plate both include a plate body, a folded edge, a pivot hole and a mounting hole; a raised area is arranged at the front end of the plate body, the pivot hole is arranged in the raised area, and the mounting hole is arranged on the plate body below the pivot hole; the upper rear end portion of the first flip fixing plate and the upper rear end portion of the second flip fixing plate are connected to form an integrated seamless structure through a connecting plate; the connecting plate is perpendicular to the plate body of the first flip fixing plate and the plate body of the second flip fixing plate, respectively, to form a supporting overlap positioning portion. The integrated design of the integrated flip fixing plate structure of the side-unloading semi-trailer solves various precision problems caused by welding connection, but the structure still independently bears the stress generated when the goods are flipped, and the bearing capacity is not strong. Utility Model Content

[0004] In order to realize the use of diagonal braces to mainly bear the stress generated when the goods are turned over and increase the structural strength of the turning fixing seat, the technical solution adopted by the utility model is: a frame with an integrally formed turning fixing seat, comprising a pair of longitudinal beams and a cross beam arranged between the pair of longitudinal beams, and a cross brace and a diagonal brace are arranged on the outer side of the longitudinal beam;

[0005] The outer end of the horizontal support is sleeved with an integrally formed flip fixing seat, and the outer end of the integrally formed flip fixing seat is provided with a flip shaft for rotating with the flip card, and the top of the diagonal support is connected to the lower surface of the integrally formed flip fixing seat and is located directly below the flip shaft.

[0006] Based on the above, in order to improve the structural strength, the one-piece molded flip fixing seat includes a flip seat bottom plate and flip seat side walls vertically arranged on both sides of the flip seat bottom plate, and the edges of the flip seat side walls and the edges of the flip seat bottom plate are respectively provided with flanges, and the flanges, the flip seat bottom plate and the flip seat side walls are integrally molded to form a U-shaped flip fixing seat.

[0007] Based on the above, in order to increase the structural stability, the width of the bottom plate of the flip seat is greater than the top width of the diagonal brace.

[0008] Based on the above, in order to improve the load-bearing capacity of the frame, the transverse brace is located directly above the diagonal brace.

[0009] Based on the above, in order to increase the structural stability, a connecting beam is further connected between the transverse brace and the longitudinal beam.

[0010] Based on the above, in order to facilitate installation, the height value of the outer end of the U-shaped flip fixing seat is higher than the height value of the inner end of the U-shaped flip fixing seat.

[0011] The utility model also provides a side-unloading semi-trailer, which is equipped with the frame with the integrally formed flip fixing seat.

[0012] The utility model has substantial features and progress compared with the prior art. Specifically, the utility model provides a frame with an integrally formed flip fixing seat, and the periphery of the integrally formed flip fixing seat adopts a flanging process to increase the strength of the integrally formed flip fixing seat; at the same time, the integrally formed flip fixing seat adopts a U-shaped structure, which can be sleeved on the end of the cross-bracing square tube, and can ensure that the diagonal brace is directly fixed to the lower part of the flip axis, and the stress at the flip axis is directly decomposed to the beam through the diagonal brace, thereby increasing the strength at the flip fixing seat, thereby solving the problem of insufficient strength and heavy weight of the traditional flip fixing seat.

[0013] Furthermore, the frame with the integrally formed flip fixing seat adopts an integrally formed process, which reduces the number of parts, simplifies the manufacturing process, and reduces assembly and welding. BRIEF DESCRIPTION OF THE DRAWINGS

The outer end of the integrally formed flip fixing seat 3 is provided with a flip shaft 4 for rotationally cooperating with a flip card 8. The top of the diagonal brace 2 is connected to the lower surface of the integrally formed flip fixing seat 3 and is located directly below the flip shaft 4. Specifically, the flip card 8 is installed on the lower surface of the vehicle box bottom plate 9.
