However, adverse weather conditions, especially strong winds, can pose a threat to the stability and safety of cranes. Traditionally, solutions to this problem have focused on improving the structure of the crane or adding additional support equipment.

[0003] However, past solutions may have some limitations, such as increasing overall weight, complexity, or difficulty in operation. Therefore, an innovative anti-wind and anti-skid device is needed to improve the operational stability of the crane in adverse weather conditions while maintaining the simplicity and convenience of the machine.

For example, some designs may require a lot of manpower or equipment to install or uninstall, which increases operating costs. In addition, some solutions may have a negative impact on the maneuverability and operability of the crane, limiting its application in narrow or complex construction sites.

[0005] Based on this, the present application provides an innovative wind-resistant and anti-skid device, which can prevent the crane from being affected by wind and improve the stability of the crane, while being simple, light and easy to operate. Utility Model Content

Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0037] See also Figures 1 to 8 :

[0038] The present application provides an embodiment of a wind-resistant and anti-slip wedge rail device for a lifting machinery, the embodiment comprising:

[0039] A supporting structure 01, a connecting rod structure 02, a wedge block 03 and a cylinder 04, wherein the connecting rod structure 02, the wedge block 03 and the cylinder 04 are arranged on the supporting structure 01, the connecting rod structure 02 is rotatably connected to the cylinder shaft 041 of the cylinder 04, the wedge block 03 is rotatably connected to the connecting rod structure 02, the supporting structure 01 is arranged in front of the crane wheel 002, the cylinder 04 drives the wedge block 03 to be lifted or lowered through the connecting rod structure 02, and when the wedge block 03 is lowered, the wedge block 03 is located in front of the crane wheel 002 and abuts against the crane track 001.

[0040] Support structure 01: Support structure 01 is the foundation of the crane's wind-resistant and anti-slip wedge rail device and can be constructed of solid materials to ensure sufficient stability. Support structure 01 is set in front of the crane wheel 002 and provides a reliable foundation for the entire device.

[0041] Connecting rod structure 02: Connecting rod structure 02 is provided on supporting structure 01, and its main function is to connect cylinder 04 and wedge block 03. Connecting rod structure 02 is designed to be rotatably connected with cylinder shaft 041 to realize the motion drive of cylinder 04. Connecting rod structure 02 is also rotatably connected with wedge block 03, so that the motion of cylinder 04 can be transmitted to wedge block 03 through connecting rod, so as to realize the lifting motion of wedge block 03.

[0042] Cylinder 04: Cylinder 04 is the power source of the anti-wind and anti-skid device. It is connected to the cylinder shaft 041 of the connecting rod structure 02 to drive the wedge 03. Cylinder 04 provides sufficient power while maintaining the stability of the device. Cylinder 04 controls the movement of wedge 03 by inflating or exhausting air to ensure that it can quickly respond to changes in wind force.

[0043] Wedge 03: Wedge 03 is a key component of the anti-slip device, which realizes the lifting movement through the rotation connection with the connecting rod structure 02. When the cylinder 04 lowers the wedge 03 through the connecting rod structure 02, the wedge 03 is located in front of the crane wheel 002 and abuts against the crane track 001, thereby providing additional support and stability.

[0044] When the crane encounters strong winds, the operator can control the cylinder 04 to lower the wedge 03 through the connecting rod structure 02. After the wedge 03 is lowered, it abuts against the track, so that the wheels of the crane cannot move, thereby reducing the impact of wind on the crane and improving the overall stability.

[0045] When the wind force decreases or there is no wind force, the operator can control the wedge block 03 to lift up through the cylinder 04 to make it disengage from the track, thereby moving the crane.

[0046] A simple and effective wind-resistant and anti-skid device is provided to improve the operational stability of the crane under strong wind conditions. It is easy to operate and has fewer parts, which helps to reduce manufacturing costs and improve maintainability. Through the design of the cylinder 04 and the connecting rod structure 02, the ability to quickly respond to wind changes is achieved, which improves the overall safety of operation. The device is highly versatile and suitable for different types of cranes and various working scenarios, providing possibilities for a wide range of applications.

[0047] See also Figures 1 to 6: In an optional embodiment, the connecting rod structure 02 includes a first rotating shaft 05, a first connecting block 06 and a thrust rod 07, the first rotating shaft 05 is connected to the cylinder shaft 041, the first rotating shaft 05 is rotatably arranged on the supporting structure 01, one end of the first connecting block 06 is fixed to the first rotating shaft 05, and the other end is rotatably connected to the thrust rod 07, and the wedge block 03 is rotatably connected to the bottom of the thrust rod 07.

[0048] In this optional embodiment, the connecting rod structure 02 is further refined to include a first rotating shaft 05, a first connecting block 06 and a thrust rod 07 to enhance the structure and operational performance of the device.

[0049] The first rotating shaft 05: The first rotating shaft 05 is connected to the cylinder shaft 041, realizing the mechanical coupling between the cylinder 04 and the connecting rod structure 02.

[0050] The first rotating shaft 05 is rotatably disposed on the supporting structure 01 , providing the cylinder shaft 041 with the ability to rotate in the horizontal direction.

[0051] First connection block 06:

[0052] The first connecting block 06 is a key connecting component, one end of which is fixed to the first rotating shaft 05, and the other end is rotatably connected to the thrust rod 07. Through the first connecting block 06, the movement of the cylinder shaft 041 is transmitted to the thrust rod 07, so that the cylinder 04 controls the thrust rod 07.

[0053] Thrust rod 07:

[0054] The thrust rod 07 is a key element connecting the first connection block 06 and the wedge block 03. One end of the thrust rod 07 is connected to the first connection block 06 through a rotatable connection, and the other end is rotatably connected to the wedge block 03. When the cylinder 04 pushes the thrust rod 07 through the first connection block 06, the movement of the thrust rod 07 will cause the wedge block 03 to rise and fall.

[0055] Wedge 03:

[0056] The wedge block 03 is a core component of the anti-skid device and is rotatably connected to the bottom of the thrust rod 07 .

[0057] When the thrust rod 07 is pushed, the wedge block 03 rises and falls accordingly, thereby achieving connection or separation with the track.

[0058] The working principle of this embodiment is as follows:

[0059] The cylinder 04 drives the first connecting block 06 to rotate through the first rotation, and the first connecting block 06 transmits the motion to the thrust rod 07 .

[0060] The movement of the thrust rod 07 causes the wedge 03 to rise and fall, connecting or disconnecting it from the track, providing anti-slip support according to actual needs.

[0061] When the stability of the crane needs to be improved, the cylinder 04 pushes the thrust rod 07 to lower the wedge 03 and abut against the track. When the wind force decreases or no additional support is needed, the cylinder 04 moves the thrust rod 07 to lift the wedge 03 out of contact with the track.

[0062] This embodiment has the following advantages: The rotatable setting of the first rotating shaft 05 improves the adaptability and maneuverability of the device in the horizontal direction. The design of the first connecting block 06 and the thrust rod 07 enables the movement of the cylinder 04 to be effectively transmitted to the wedge block 03, thereby realizing efficient operation of the device. The connecting rod structure 02 is further optimized, thereby improving the stability and reliability of the entire device. The rotatable connection of the wedge block 03 to the bottom of the thrust rod 07 ensures smooth movement during the anti-slip support process. Through the design of this embodiment, the device increases some structural flexibility and operational performance while maintaining simplicity.

[0064] In an optional embodiment, it further includes a second connecting block 08 , one end of which is fixed to the first rotating shaft 05 , and the other end of which is rotatably connected to the cylinder shaft 041 .

[0065] In this optional embodiment, a second connecting block 08 is added to further optimize the connecting rod structure 02 and improve the operating performance and stability of the device.

[0066] Second connecting block 08: The second connecting block 08 is a component connected to the first rotating shaft 05 and the cylinder shaft 041. One end is fixed to the first rotating shaft 05, and the other end is rotatably connected to the cylinder shaft 041, thus realizing the mechanical connection between the first rotating shaft 05 and the cylinder shaft 041. The design of the second connecting block 08 enables the movement of the cylinder shaft 041 to be effectively transmitted to the entire connecting rod structure 02.

[0067] Working principle:

[0068] The movement of the cylinder shaft 041 is transmitted to the first rotating shaft 05 through the second connecting block 08 .

[0069] The rotation of the first rotating shaft 05 drives the first connecting block 06, which is then transmitted to the thrust rod 07. The movement of the thrust rod 07 causes the wedge block 03 to rise and fall, thereby achieving connection or separation with the track.

[0070] In an optional embodiment, the cylinder 04 is longitudinally mounted on the supporting structure 01, and the cylinder shaft 041 drives the second connecting block 08 to rotate by moving up and down.

[0071] In an optional embodiment, the cylinder shaft 041 is rotatably connected to the second connecting block 08 via a second rotating shaft 09 .

[0072] In this optional embodiment, the cylinder 04 is installed vertically on the support structure 01, perpendicular to the ground. Such a vertical installation makes the movement direction of the cylinder 04 more suitable for the lifting movement in the vertical direction.

[0073] The cylinder shaft 041 drives the second connection block 08 to rotate by longitudinal up and down movement. The second connection block 08 is fixed to one end of the first rotating shaft 05, so as to realize the transmission of the movement of the cylinder shaft 041 and the first rotating shaft 05.

[0074] In this optional embodiment, the cylinder shaft 041 is rotatably connected to the second connecting block 08 via the second rotating shaft 09 .

[0075] This design enables the movement of the cylinder shaft 041 to more flexibly affect the entire connecting rod structure 02.

[0076] When the cylinder 04 rises, the rising movement of the cylinder shaft 041 is transmitted to the first rotating shaft 05 through the second connecting block 08 .

[0077] The rotation of the first rotating shaft 05 drives the first connecting block 06 , and then is transmitted to the thrust rod 07 .

[0078] The movement of the thrust rod 07 causes the wedge 03 to rise and fall, thereby connecting or disconnecting from the track.

[0079] The second connecting block 08 is driven to rotate by the up and down movement of the cylinder shaft 041, making the entire system more flexible and efficient.

[0080] The rotational connection between the second connecting block 08 and the cylinder shaft 041 increases the connection flexibility of the system, making the influence of the movement of the cylinder shaft 041 on the entire connecting rod structure 02 more controllable.

[0081] This optional embodiment improves the movement efficiency and adaptability of the device by changing the installation method of the cylinder 04 and adding a connection design.

[0082] In an optional embodiment, the first connecting block 06 is rotatably connected to the thrust rod 07 via a third rotating shaft 10 .

[0083] In an optional embodiment, the wedge block 03 is provided with an arc surface 11, and the arc surface 11 faces the crane wheel 002. The bottom of the wedge block 03 is provided with an abutment plane 12, and the abutment plane 12 is parallel to the crane track 001.

[0084] In this optional embodiment, the design of the wedge block 03 is further optimized, and a curved surface 11 is provided on the upper portion.

[0085] The arc surface 11 faces the crane wheel 002. Such a design helps to better adapt to the shape of the wheel and provide a wider abutment surface.

[0086] The bottom of the wedge block 03 is provided with an abutment plane 12 which is parallel to the crane rail 001 .

[0087] The provision of the abutment plane 12 helps ensure that the wedge block 03 remains stable when abutting the rail, providing a more secure support.

[0088] When the cylinder 04 drives the wedge 03 to be lowered, the arc surface 11 faces the crane wheel 002.

[0089] The arcuate surface 11 adapts to the shape of the wheel, ensuring that the wedge 03 maintains stable contact with the wheel when it is raised.

[0090] The abutment plane 12 is parallel to the track, ensuring that the abutment between the wedge block 03 and the track is more secure in the vertical direction.

[0091] The setting of the arc surface 11 enables the wedge 03 to better adapt to the shape of the crane wheel 002, and improves the fit with the wheel. The design of the abutment plane 12 ensures that the abutment between the wedge 03 and the track is more stable, which helps to provide reliable support. The design optimization of this optional embodiment increases the stability of the wedge 03 when abutting the track, and improves the performance of the entire device. By considering the shape and abutment method of the wedge 03, the adaptability and connection firmness between the anti-wind and anti-skid device and the crane wheel 002 are improved.

The two connecting plates 13 constitute the main structure of the thrust rod 07, which can better share the thrust and withstand the lifting movement of the wedge block 03.

[0094] The connecting column 14 is connected between the connecting plates 13 to play the role of connection and support. The connecting column 14 forms a stable thrust rod 07 structure by connecting the connecting plates 13.
