Description
Technical Field

[0002] The clamping mechanism of the tipper unhooking robot is an important component of the unhooking robot and is used to realize the automatic unhooking function.
[0003] In the prior art, the clamping assembly of the traditional unhooking robot is clamped by a clamping cylinder or a clamping claw. When the train is unhooked, the unhooking is performed by clamping the unhooking rod and then flipping, pushing and pulling. In the above operation process, the clamping assembly needs to withstand a large tensile force or torque, and must have a good clamping strength to meet the train unhooking. The clamping methods such as the cylinder claw are controlled by air pressure. While the clamping force is limited and varies with the change of air pressure, the clamping effect can be affected when the air pressure is unstable. Secondly, the traditional design of clamping by claws also has certain disadvantages. When the air pressure is insufficient or the tension or torque borne by the claws is large, the unhooking rod may be separated from the inner walls of the two claws, thereby causing the unhooking to fail and affecting the unhooking efficiency. Therefore, a clamping mechanism of a tipping machine unhooking robot is urgently needed to solve the above problems. Utility Model Content
