Description

Technical Field

[0001] The utility model relates to the field of semi-trailer frames, in particular to a reversible gooseneck connecting slope and a frame. Background Art

[0002] A gooseneck trailer is a type of heavy-duty semi-trailer. The front looks like a gooseneck. This type of semi-trailer has no guardrails and the load-bearing points are mainly in the middle and rear part of the carriage. It is generally used to transport large excavators and other engineering equipment or large machinery.

[0003] Chinese utility model patent publication number CN203544179U discloses a gooseneck semi-trailer and its front neck support structure. This front neck support structure includes a front neck support platform, which is mounted on the front neck and forms a support surface; and a front neck ladder, located at the junction of the front neck and the cargo platform, forming a slope connecting the support surface and the cargo platform. However, this front neck support structure requires manual installation and disassembly, making it inconvenient to use.

[0004] Therefore, this field needs a new technical solution to solve the above problems. Summary of the Invention

[0005] To improve or resolve the inconvenient manual installation and removal of the front neck support structure in the prior art, the present invention provides a reversible gooseneck connection ramp. The gooseneck connection ramp comprises: a support frame, one end of which is adapted to form an articulated connection with the vehicle frame body and the other end of which is adapted to overlap the gooseneck; a driving member, one end of which is articulated with the support frame and the other end of which is adapted to form an articulated connection with the gooseneck; the support frame having a sloped surface that connects the gooseneck support surface and the cargo platform of the vehicle frame body when one end of the support frame is raised.

[0006] The present invention provides a reversible gooseneck ramp, comprising a carrier and a drive member. The carrier has a first end hingedly connected to the vehicle frame, and the other end is attached to the gooseneck. This allows the drive member to rotate the carrier, connecting the carrier's ramped surface to the gooseneck's load-bearing surface and the vehicle frame's cargo platform. The drive member has one end hingedly connected to the carrier, and the other end hingedly connected to the gooseneck, enabling one end of the carrier to be raised and lowered. When the ramped surface is raised, it connects the load-bearing surface and the cargo platform, facilitating the parking of machinery on the load-bearing surface. When the ramped surface is lowered, it cooperates with the cargo platform, serving as a partial cargo platform, facilitating the parking of machinery on the cargo platform. Through the aforementioned arrangement, the present invention uses the drive member to drive the carrier to rotate. When the ramped surface is raised, it connects the load-bearing surface and the cargo platform, facilitating the parking of machinery on the load-bearing surface. When the ramped surface is lowered, it cooperates with the cargo platform, serving as a partial cargo platform, facilitating the parking of machinery on the cargo platform. This arrangement eliminates the need for manual disassembly, making it easy to use.

[0007] Furthermore, the supporting frame includes a first side panel, a second side panel arranged opposite to the first side panel, a first end panel connecting the first side panel and the second side panel, an intermediate panel arranged opposite to the first end panel, and a mounting plate connected to the driving member; an articulated seat is provided on the mounting plate to form an articulated connection with the driving member.

[0008] Furthermore, a reinforcing plate is provided between the first side plate and the second side plate; one end of the mounting plate is connected to the reinforcing plate, and the other end is connected to the middle plate.

[0009] Furthermore, the supporting frame also includes a second end plate arranged opposite to the first end plate, and the second end plate is suitable for abutting against the gooseneck.

[0010] Furthermore, the supporting frame further includes a bottom plate arranged above the first side plate and the second side plate, and the slope surface is formed on the bottom plate.

[0011] Furthermore, the driving component is a hydraulic cylinder.

[0012] To improve or resolve the technical problem in the prior art of the front neck supporting structure requiring manual installation and removal, resulting in inconvenience in use, the present invention provides a frame. The frame comprises a frame body having a cargo platform; a gooseneck fixedly connected to the frame body and having a load-bearing surface; a gooseneck connecting ramp as described above; a supporting frame of the gooseneck connecting ramp having one end articulated with the frame body and the other end overlapped on the gooseneck, the supporting frame having a sloped surface connecting the load-bearing surface and the cargo platform; and a driving member having one end articulated with the supporting frame and the other end articulated with the gooseneck.

[0013] Furthermore, the vehicle frame includes a main beam and side brackets arranged on both sides of the main beam, and the load-bearing frame is hingedly connected to the side brackets.

[0014] Furthermore, the gooseneck includes a lap joint supporting the supporting frame, a bearing portion having the bearing surface, and a connecting portion connecting the lap joint and the bearing portion; one end of the driving member forms a hinged connection with the lap joint.

[0015] In summary, compared with the prior art, the present invention has the following beneficial effects:

[0016] The first end of the carrier is hingedly connected to the frame body, and the other end is overlapped on the gooseneck, so that the driving part drives the carrier to rotate, so that the sloped surface of the carrier is connected to the bearing surface of the gooseneck and the cargo platform of the frame body; one end of the driving part is hingedly connected to the carrier, and the other end is hingedly connected to the gooseneck, which can drive one end of the carrier to rise and fall; when the sloped surface is raised, it can connect the bearing surface and the cargo platform, which is convenient for parking the machine on the bearing surface; when the sloped surface is lowered, it can cooperate with the cargo platform and serve as a part of the cargo platform, which is convenient for parking the machine on the cargo platform.

Figure 3 This is a second isometric view of an embodiment of the vehicle frame of the present invention. Figure 1 、 Figure 2 and Figure 3As shown, one end of the carrier frame 1 is hingedly connected to the vehicle frame body 100, and the other end is attached to the gooseneck 200. In one or more embodiments, the carrier frame 1 includes a first side panel 11, a second side panel 12, a first end panel 13, an intermediate panel 14, a second end panel 15, a mounting panel 16, and a bottom panel 17. The first and second side panels 11, 12 are arranged opposite each other and have identical shapes and structures. The ends of the first and second side panels 11, 12 proximate the gooseneck 200 are recessed upward to form a groove that matches the gooseneck 200, so that the sloped surface 171 on the bottom panel 17 is flush with the cargo platform of the vehicle frame body 100. Furthermore, the first end panel 13 is disposed at the end away from the gooseneck 200 and connects the first and second side panels 11, 12. A hinged seat is provided on the first end panel 13, which forms an hinged connection with the vehicle frame body 100 via the hinged seat. Specifically, two hinged seats are provided, one near each end of the first end plate 13. Furthermore, an intermediate plate 14 is located near the gooseneck 200 and connects the first side plate 11 and the second side plate 12.
