DETAILED DESCRIPTION

[0017] A specific implementation mode of the present utility model is described in detail below in conjunction with the accompanying drawings, but it should be understood that the protection scope of the present utility model is not limited by the specific implementation mode.

[0018] Embodiment 1:

[0019] like Figure 1 As shown, a tool for lifting tires of engineering vehicles comprises a basic beam 1 and a lifting connector 2 slidably connected to the top of the basic beam 1. Specifically, a sliding plate 51 is connected to the lifting connector 2. Both left and right ends of the sliding plate 51 are slidably guided by guide rods 52. The lower end of the guide rod 52 is fixedly connected to the basic beam 1.

[0020] The upper end of the lifting connection part 2 has a lifting connection end 21. Specifically, the lifting connection end 21 is a lifting ring, which is used to connect the lifting equipment. The lower end of the lifting connection end 21 is connected to the clamp automatic closing device 3. The clamp automatic closing device 3 is a clamp automatic closer, and its lower end is connected to the T-hook 31. The upper end of the basic beam 1 is connected to the hanging rod 32 that cooperates with the T-hook 31. The two sides of the lifting connection part 2 are respectively hingedly connected to the connecting rod assemblies. The ends of the connecting rod assemblies on both sides are connected to the lifting claws 41. There is a rotating fulcrum 42 between the connecting rod assembly and the basic beam 1. Through the up and down movement of the lifting connection part 2, the lifting claws 41 are opened and retracted under the drive of the connecting rod assembly.

[0021] Specifically, the connecting rod assembly includes a straight connecting rod 43 and a bent connecting rod 44 which are hingedly connected to the lifting connecting member 2. The middle part of the bent connecting rod 44 is connected to the base beam 1 through a rotating fulcrum 42, and the end of the bent connecting rod 44 is connected to the lifting claw 41.

[0022] The working principle or use method of the utility model:

[0023] Special combination Figure 2-3 As shown, first, the tire and the rim are assembled and laid flat, and at the same time, the T-shaped hook 31 is hooked on the hanging rod 32, so that the hanger is in a locked state;

[0024] Insert the lifting claw 41 into the middle of the wheel rim and continue to lower the tool. When the lower end surface of the base beam 1 contacts the upper end surface of the tire, the T-shaped hook 31 of the clamp automatic closing device 3 hits the base beam 1 under the action of gravity. The T-shaped hook 31 will automatically rotate 90 degrees after being hit, so that the T-shaped hook 31 is parallel to the hanging rod 32, and the locking state is released at this time.

[0025] The tool is lifted, and the lifting connector 2 drives the lifting claws 41 to open to both sides through the connecting rod assembly, and the lifting claws 41 hook the inner edge of the rim to lift the entire tire;

[0026] After the transfer is completed, the tool is lowered, and the T-shaped hook 31 hits the foundation beam 1 again, and the T-shaped hook 31 rotates again. After the collision, the T-shaped hook 31 is hooked with the hanging rod 32, and the entire sling is in a locked state.

[0027] The above disclosures are only several specific embodiments of the present invention. However, the embodiments of the present invention are not limited thereto. Any changes that can be conceived by those skilled in the art should fall within the protection scope of the present invention.
