Thus, a feature identified as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, "plurality" means two or more, unless otherwise specifically defined.

[0029] Reference below Figures 1 to 4 An adjustable anti-tipping forklift frame according to an embodiment of the present invention is described.

[0030] An embodiment of the present application discloses an adjustable anti-tipping forklift frame, comprising: a frame body 1, a front top cylinder 2 and an adjustable structure 3.

[0031] Among them, arc-shaped guide rails 11 and adjustment holes 12 are symmetrically provided on the two side panels of the front part of the frame body 1; there are two front top cylinders 2, and the two front top cylinders 2 are symmetrically arranged on the inner side of the frame body 1; the adjustable structure 3 includes an adjusting rod 1 31, an adjusting rod 2 32, a connecting piece and an auxiliary wheel 34, the adjusting rod 1 31 is hinged to the end of the adjusting rod 2 32 through a cylindrical pin 5, the auxiliary wheel 34 is installed at the other end of the adjusting rod 2 32, the cylindrical pin 5 is installed in the adjustment hole 12, and the two ends of the connecting piece are respectively connected to the adjusting rod 1 31 and the adjusting rod 2 32; there are two groups of adjustable structures 3, and the two groups of adjustable structures 3 are symmetrically distributed on the outside of the frame body 1; the telescopic end of the front top cylinder 2 is connected to the adjusting rod 1 31 through the front top cylinder pin 6, and the front top cylinder pin 6 is passed through the arc-shaped guide rail 11.

[0032] In this embodiment, the adjustable structure 3 is driven by the front oil cylinder 2 to adjust the center of gravity of the vehicle. Specifically, when the telescopic rod of the front oil cylinder 2 is extended, the telescopic rod synchronously drives the movable end of the adjusting rod 1 31 of the adjustable structure 3 to move along the trajectory of the arc-shaped guide rail 11 through the front oil cylinder pin 6. When the movable end of the adjusting rod 1 31 moves synchronously, because the adjusting rod 1 31 is connected to the adjusting rod 2 32 by a connector and the other end is mounted on the side panel together with the adjusting rod 2 32 via a fixed pin, when the movable end of the adjusting rod 1 31 moves with the telescopic rod, the other fixed end rotates together with the adjusting rod 2 32 about the fixed pin. During the rotation process, the auxiliary wheel 34 mounted on the adjusting rod 2 32 also falls from the raised state. When the auxiliary wheel 34 falls to the ground, the auxiliary wheel 34 can provide auxiliary support for the entire vehicle and adjust the center of gravity of the entire vehicle, shifting the center of gravity of the entire vehicle backward, thereby effectively preventing the vehicle from tipping over.

[0033] When the telescopic rod of the front oil cylinder 2 retracts, the movable end of the adjusting rod 1 31 moves in the opposite direction along the arc guide rail 11 together with the telescopic rod. At the same time, the fixed end of the adjusting rod 1 31 rotates in the opposite direction around the fixing pin together with the adjusting rod 2 32. In this way, the auxiliary wheel 34 is lifted together with the adjusting rod 2 32 and returns to the lifted state.

[0034] In some embodiments, the connecting member is a downward-pressing oil cylinder 33 , and the telescopic end and the fixed end of the downward-pressing oil cylinder 33 are hinged to the adjusting rod 1 31 and the adjusting rod 2 32 respectively.

[0035] When the lifting lever 31 is lifted up, the second adjusting lever 32 is lifted up, and the second adjusting lever 32 is lifted up, so that the lifting lever 31 and the second adjusting lever 32 can be lifted up and down synchronously.

[0036] In some embodiments, the connecting member can also be other connecting structures, such as connecting rods, connecting steel ropes, etc., which are not specifically limited here.

[0037] In some embodiments, for example Figure 3As shown, the adjusting rod 1 31 includes: a clamping plate 1 311 and a clamping plate 2 312 . The clamping plate 1 311 and the clamping plate 2 312 are spliced ​​together to form the adjusting rod 1 31 . The end of the adjusting rod 2 32 is located between the clamping plate 1 311 and the clamping plate 2 312 .

[0038] For example Figure 3 As shown, the hinged structure of the downward-pressing oil cylinder 33 and the adjusting rod 1 31 is specifically as follows: the fixed end of the downward-pressing oil cylinder 33 is hinged between the clamping plate 1 311 and the clamping plate 2 312. Such a design can make the force on the adjusting rod 1 31 more balanced and effectively protect the safety of the adjusting rod 1 31. At the same time, the adjusting rod 1 31 can provide a more stable supporting force for the downward-pressing oil cylinder 33.

[0039] For example Figure 3 As shown, the hinged connection between the downward-pressing cylinder 33 and the second adjusting rod 32 is specifically as follows: a mounting slot is defined on the upper end surface of the second adjusting rod 32, with support bosses 321 symmetrically arranged on either side of the mounting slot. The telescopic end of the downward-pressing cylinder 33 is located within the mounting slot and connected to the support bosses 321 via the downward-pressing cylinder pin 4. The design of the support bosses 321 enhances the structural strength of the connection between the downward-pressing cylinder 33 and the second adjusting rod 32.

[0040] In some embodiments, a front jacking cylinder support plate 81 is provided inside both side panels of the front portion of the vehicle frame body 1, and the fixed end of the front jacking cylinder 2 is hingedly connected to the front jacking cylinder support plate 81. The front jacking cylinder support plate 81 can provide sufficient support for the front jacking cylinder 2 to ensure the stability of the front jacking cylinder 2 during operation.

[0041] For example Figure 2 As shown, a mounting hole 81 is opened on the front top cylinder support plate 81 , and the fixed end of the front top cylinder 2 is hinged to the front top cylinder support plate 81 through a frame locating pin 7 , and the frame locating pin 7 is installed in the mounting hole 81 .

[0042] The present invention also provides an anti-tipping forklift, comprising the adjustable anti-tipping forklift frame in the above embodiment. Therefore, the anti-tipping forklift with the adjustable anti-tipping forklift frame has all the above technical effects, which will not be described one by one here.

[0043] Other structures and operations of the adjustable anti-tipping forklift frame and the anti-tipping forklift according to the embodiment of the present invention are well known to those skilled in the art and will not be described in detail here.
