The second slider 32 is vertically slidably connected to the connecting plate 12. The two ends of the second scissor arm 31 are respectively rotatably connected to the fixed plate 11 and the second slider 32. The first scissor arm 21 is installed with a connecting sleeve 24, and the connecting sleeve 24 is rotatably connected to the second scissor arm 31. The connecting plate 12 is installed with a first pin shaft 23 rotatably connected to the first scissor arm 21. The fixed plate 11 is installed with a second pin shaft 33 rotatably connected to the second scissor arm 31. The two ends of the telescopic drive member 13 are respectively rotatably connected to the first pin shaft 23 and the second pin shaft 33. The telescopic drive member 13 is a hydraulic cylinder. The second scissor arm 31 is fixedly connected with a fixing sleeve 34, and the fixing sleeve 34 is rotatably connected to the connecting sleeve 24.

[0038] The rolling mechanism includes a rotating oil cylinder 41 and a rolling frame 42. The rotating oil cylinder 41 is fixedly mounted on the connecting plate 12, and the rolling frame 42 is mounted on the output shaft of the rotating oil cylinder 41. An observation port 14 is provided at the upper end of the connecting plate 12.

[0039] The clamp arm 51 is rotatably mounted on the rolling frame 42, and the rolling frame 42 is fixedly connected to the support frame 43. A clamping drive 52 is provided between the support frame 43 and the clamp arm 51. The two ends of the clamping drive 52 are rotatably connected to the support frame 43 and the clamp arm 51, respectively. The clamping drive 52 is a hydraulic cylinder. The connecting sleeve 24 is slidably connected to the first scissor arm 21. The first slider 22 is provided with a third pin 25 rotatably connected to the first scissor arm 21. A flip drive 26 is provided between the third pin 25 and the connecting sleeve 24. The two ends of the flip drive 26 are connected to the connecting sleeve 24 and the third pin 25, respectively.

The clamp arm 51 is provided with a clamping plate 53, which is perpendicular to the clamp arm 51 and fixedly connected to the lower part of the clamp arm 51. The clamp arm 51 is provided with a weight reduction groove 54.

[0040] The fixing plate 11 is mounted on a forklift, and the clamping driving member 52 drives the clamping arm 51 to rotate on the supporting frame 43, so that the clamping arm 51 drives the clamping plate 53 to clamp the tire, thereby achieving the function of clamping the tire.

[0041] This embodiment has the following advantages:

[0042] The telescopic drive member 13 extends and shortens to drive the connecting plate 12 to extend or retract. During the movement of the connecting plate 12, the first scissor arm 21 and the second scissor arm 31 rotate with the movement of the connecting plate 12, and the first slider 22 and the second slider 32 slide with the rotation of the first scissor arm 21 and the second scissor arm 31, respectively, to adjust the tire loading and unloading position, which is convenient for loading and unloading tires. When the telescopic drive member 13 and the flip drive member 26 stop moving, the first scissor arm 21, the second scissor arm 31 and the telescopic drive member 13 form a stable triangular structure, so that the scissor arm mechanism remains in a locked state. The clamping arm 51 is driven to rotate by the rolling mechanism, so that the clamped tire rolls around the horizontal axis, which plays a role in adjusting the tire angle and is convenient for loading and unloading tires.

[0043] The scissor arm mechanism and the rolling mechanism can be used to adjust the position and angle of the tire, which is suitable for narrow and complex loading and unloading environments. The structure is stable and reliable, and the advantage of convenient loading and unloading of tires is achieved.

[0044] The rotating oil cylinder 41 drives the rolling frame 42 and the clamping arm 51 to rotate around the horizontal axis, thereby realizing the function of driving the clamping arm 51 and the clamped tire to roll around the horizontal axis through the rolling mechanism.

[0045] The tire is placed between the two clamping arms 51 , and the clamping arms 51 are driven to rotate on the rolling frame 42 , so that the two clamping arms 51 are brought close to each other and tighten the tire, thereby achieving the function of clamping the tire.

[0046] The clamping drive member 52 is extended and shortened to drive the clamping arm 51 to rotate on the rolling frame 42 , thereby realizing the function of driving the clamping arm 51 to rotate on the rolling frame 42 .

[0047] refer to Figure 2 and Figure 3 Sliding the connecting sleeve 24 on the first scissor arm 21 can drive the second scissor arm 31 to rotate, so that the second scissor arm 31 pushes the connecting plate 12 to tilt, thereby driving the clamping arm 51 and the clamped tire to tip over, thereby driving the tire to flip in different directions, facilitating the adjustment of the tire loading and unloading angle, and achieving the advantage of easy use.

[0048] The connecting sleeve 24 is driven to slide on the first scissor arm 21 by the flip driving member 26 to extend and shorten, thereby realizing the function of driving the connecting sleeve 24 to slide on the first scissor arm 21 .

[0049] The clamping plate 53 clamps the tire, increasing the contact area between the clamping arm 51 and the tire, making the tire clamping more reliable, reducing the risk of the tire falling and being damaged, and being able to carry multiple tires at a time. The clamping plate 53 is fixedly connected to the lower half of the clamping arm 51, thereby reducing the length of the clamping plate 53 extending from the bottom of the clamping arm 51, preventing the clamping plate 53 from being stuck by a forklift when the flip driving member 26 drives the clamping arm 51 to tip forward, thereby improving reliability.

[0050] The weight-reducing groove 54 can reduce the weight of the clamp arm 51 , reduce the load on the scissor arm mechanism and the rolling mechanism, and improve reliability.

[0051] An observation port 14 is provided at the upper end of the connecting plate 12 to facilitate observation of the relative position of the tire and the clamping arm 51 , thereby facilitating loading and unloading of the tire.

[0052] The second scissor arm 31 and the connecting sleeve 24 are connected by the fixing sleeve 34 , so as to strengthen the function of the second scissor arm 31 and improve the structural stability between the second scissor arm 31 and the connecting sleeve 24 .
