[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0019] In the description of the present invention, it should be understood that terms such as "opening", "upper", "lower", "thickness", "top", "middle", "length", "inside", "all around" and the like indicating orientation or positional relationship are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as limiting the present invention.

[0020] Example

[0021] In order to solve the problem that the dust-free crane in the prior art is prone to cause the goods to shake during the movement of suspended goods, which is a high risk problem, refer to Figure 1-Figure 3As shown, the present application discloses an anti-sway assembly for a mechanical arm of a dust-free crane, including a power hoist 10, a fixed tube 20 and a guide rod 30. The guide rod 30 is inserted into the fixed tube 20 and can be movably extended and retracted from the bottom of the fixed tube 20. A linear slide rail 31 is fixed to at least one side of the guide rod 30 in its height direction. A slider 21 is fixed to the inner wall of at least one side of the fixed tube 20 in its height direction and is slidably connected to the linear slide rail 31. In a specific implementation, at least two sliders 21 are arranged in the fixed tube 20. An anti-slip baffle 32 is arranged on the top of the guide rod 30. The interior of the fixed tube 20 is fixed to the linear slide rail 31 for sliding. A stop structure 22 is arranged above the block 21. When the anti-slip baffle 32 is pressed against the stop structure 22, the guide rod 30 will stop extending from the fixed tube 20. A connecting seat 40 is fixed to one side of the bottom of the guide rod 30 (the connecting seat 40 can be used to fix a clamp 50 for clamping goods). The power hoist 10 is arranged outside the fixed tube 20, and the chain rope 11 of the power hoist 10 is connected to the connecting seat 40. Specifically, a hook 111 is arranged on the chain rope 11 of the power hoist 10 of the present application, and a lifting ear 41 is arranged above the connecting seat 40, and the hook 111 is hooked in the lifting ear 41.

[0022] In addition to the above structure, the present application also has an integral mounting plate 23 on the top of the fixed pipe 20. During the specific installation process, the mounting plate 23 is to be installed with the electric hoist trolley of the dust-free crane or with the crossbeam of the dust-free crane (the electric hoist trolley or the crossbeam is not shown in the present application). Together with it, the power hoist 10 of the present application is also to be installed on the electric hoist trolley of the dust-free crane or the crossbeam of the dust-free crane.

[0023] In one specific implementation scheme, the stop structure 22 includes four stop rods 221, which are inserted in pairs on opposite sides of the interior of the fixed tube 20. When the anti-slip baffle 32 is pressed against the four stop rods 221, the guide rod 30 will stop extending from the fixed tube 20, thereby avoiding the risk of the guide rod 30 falling off the fixed tube 20 and having a higher safety factor.

[0024] It can be selected that the power hoist 10 is an electric hoist or a winch. In the specific implementation, if other types of power hoists 10 can also meet the use requirements of this application, personnel in this technical field can also choose them adaptively.

[0025] The specific implementation principle of this application is described below:

[0026] Driven by the power hoist 10, the connecting seat 40 will realize lifting and lowering movement, and in the process of the connecting seat 40 performing the lifting and lowering movement, the linear slide rail 31 on the guide rod 30 will cooperate with the slider 21 in the fixed tube 20 to make the guide rod 30 stably extend and retract in the fixed tube 20. In addition, by arranging four stop rods 221 in the fixed tube 20 to cooperate with the anti-slip baffle 32 on the top of the guide rod 30, it can be ensured that the guide rod 30 will not slip, thereby avoiding the guide rod 30 from slipping out and hitting the operator or other equipment in the workshop, thereby improving the overall safety factor.
