Description

Technical Field

[0001] The utility model relates to the technical field of loaders, in particular to a dual-purpose fork and a loader. Background Art

[0002] The clamping fork is composed of an upper fork tine and a lower fork body. The upper fork tine is connected to the lower fork body through a pin shaft, and the upper fork tine is driven by a cylinder. The cylinder drives the upper fork tine to rotate relative to the pin shaft, thereby causing the upper fork tine and the lower fork tine of the lower fork body to clamp the material.

[0003] There are two types of forks. One is that the middle surface of the upper fork tine coincides with the middle surface of the lower fork tine on the same side. When the upper fork tine rotates downward, the front end of the upper fork tine will collide with the front end of the lower fork tine, forming a mutually opposing posture. This type of fork is called a top-to-top fork. The other is that the middle surface of the upper fork tine does not coincide with the middle surface of the lower fork tine on the same side, and there is a certain distance between the two middle surfaces. When the upper fork tine rotates downward, it will not collide with the front end of the lower fork tine, but will be offset from the lower fork tine and continue to move downward until the material is clamped. This type of fork is called a staggered tooth fork.

[0004] In order to save costs and increase the versatility of the fork in the prior art, a dual-purpose fork with two working states, namely, aligned teeth and staggered teeth, has emerged. Usually, an offset structure is provided on the upper fork tine for changing the position of the upper fork tine so that the upper fork tine and the lower fork tine are aligned or staggered. However, during adjustment, the pin shaft connecting the upper fork tine and the oil cylinder driving the upper fork tine also need to be changed, which results in low adjustment efficiency and affects the switching efficiency of the fork.

[0005] Therefore, a dual-purpose forklift and loader are needed to solve the above problems. Utility Model Content

[0047] As Figures 1 to 4 shown, in this embodiment, a dual-purpose fork is provided. The dual-purpose fork includes a fork body 10, lower fork teeth 30 and a driving mechanism 40. The fork body 10 is provided with a support frame 11. The support frame 11 is provided with a slideway 1111. Two upper fork teeth 20 are rotatably arranged on the fork body 10. Two lower fork teeth 30 are slidably arranged on the slideway 1111. The driving mechanism 40 is in transmission connection with both of the two lower fork teeth 30. The two lower fork teeth 30 slide along the slideway 1111 under the drive of the driving mechanism 40, so that the two lower fork teeth 30 approach or move away from each other. Specifically, in this embodiment, the two upper fork teeth 20 are rotatably arranged on the fork body 10 through a pin shaft, and a telescopic oil cylinder is arranged between the upper fork teeth 20 and the fork body 10 for driving the upper fork teeth 20 to rotate around the pin shaft, so as to clamp or loosen the material by the upper fork teeth 20 and the lower fork teeth 30. The two lower fork teeth 30 are slidably arranged on the slideway 1111 of the support frame 11, and the lower fork teeth 30 are in transmission connection with the driving mechanism 40. The driving mechanism 40 can drive the lower fork teeth 30 to slide along the slideway 1111, so that the two lower fork teeth 30 approach or move away from each other. When the front ends of the lower fork teeth 30 and the upper fork teeth 20 can touch each other, the dual-purpose fork is in the tooth-aligning state, and at this time, the opposite-tooth fork operation can be carried out. When the front ends of the lower fork teeth 30 and the upper fork teeth 20 cannot touch each other, the dual-purpose fork is in the staggered-tooth state, and at this time, the staggered-tooth fork operation can be carried out. This dual-purpose fork can drive the two lower fork teeth 30 to approach or move away from each other through the driving mechanism 40, so that the dual-purpose fork can be switched between the tooth-aligning and staggered-tooth states. The structure is simple, the switching is convenient, the use convenience of the dual-purpose fork can be improved, and the fork efficiency can be improved.

[0048] In this embodiment, the support frame 11 includes an upper support plate 111, a lower support plate 112 and a connecting plate 113. The two connecting plates 113 are respectively connected between the upper support plate 111 and the lower support plate 112. The slideway 1111 is arranged on the upper support plate 111.

[0049] Further, as Figure 5 and Figure 6As shown in the figure, the driving mechanism 40 includes a first driving member 41 and a second driving member 42. The first driving member 41 is installed at one end of the support frame 11, and the second driving member 42 is installed at the end of the support frame 11 away from the first driving member 41. The first driving member 41 is used to drive one of the lower fork teeth 30 to slide along the slideway 1111, and the second driving member 42 is used to drive the other lower fork tooth 30 to slide along the slideway 1111. Specifically, in this embodiment, the first driving member 41 and the second driving member 42 are respectively used to drive the two lower fork teeth 30, so that the two lower fork teeth 30 can be controlled separately, thereby improving the flexibility of the sliding of the lower fork teeth 30.

[0050] In this embodiment, please refer to Figure 9 and Figure 10 , the first driving member 41 and the second driving member 42 are telescopic oil cylinders. In other embodiments, the first driving member 41 and the second driving member 42 can also adopt other components with the same technical effects, such as telescopic air cylinders, which will not be elaborated here.

Specifically, a hinge seat 1131 is arranged on the connecting plate 113, and the cylinder body of the telescopic oil cylinder is rotatably arranged on the hinge seat 1131 through a rotating pin 1132. One end of the rotating pin 1132 can abut against the hinge seat 1131, and an opening is arranged at the other end of the rotating pin 1132, and a split pin 1133 is arranged in the opening, thereby fixing the cylinder body of the telescopic oil cylinder to the hinge seat 1131.

[0052] Furthermore, as shown in Figure 7 and Figure 8 , the driving mechanism 40 further includes a first bracket 43 and a second bracket 44. The first bracket 43 is arranged at the output end of the first driving member 41, and the first bracket 43 is used to limit the position of one of the lower fork teeth 30. The second bracket 44 is arranged at the output end of the second driving member 42, and the second bracket 44 is used to limit the position of the other lower fork tooth 30. Specifically, in this embodiment, the first bracket 43 can limit the position of one of the lower fork teeth 30, and the first driving member 41 drives the first bracket 43 to adjust the position of the lower fork tooth 30 limited by the first bracket 43, thereby avoiding the reduction of the strength of the lower fork tooth 30 caused by the direct connection between the first driving member 41 and the lower fork tooth 30, and ensuring the use performance of the dual-purpose fork. The purpose of the second bracket 44 is the same and will not be elaborated here.

[0053] In another embodiment, the first driving member 41 and the second driving member 42 may also be a lead screw and a lead screw nut assembly. The lead screw is driven by a motor. The lead screw nut is mounted on the first bracket 43.
