[0026] Specifically, when encountering strong winds, the windproof locking rod 17 is passed through the walking wheel hole above the walking wheel 3. After the windproof locking rod 17 is adjusted to the buckle, the upper card plate positioning adjustment hole 10 and the lower card plate positioning adjustment hole 12 of the card plate 7 are aligned with the corresponding upper card plate positioning screw 9 and the lower card plate positioning bolt 8 respectively, and the nut is tightened to fix the card plate 7 and the arc baffle 6. At the same time, starting the hydraulic rod 13 can drive the moving block 14 to move toward the bottom of the walking trolley 1, and the L-shaped clamping plate 15 is pulled by the first spring 16 to be in an open state. When the L-shaped clamping plate 15 contacts the fixed rail 4, the L-shaped clamping plate 15 will gradually clamp with the continued extension and contraction of the hydraulic rod 13 until the L-shaped clamping plate 15 completely clamps the fixed rail 4, which can further prevent the walking wheel 3 of the walking trolley 1 from rolling due to wind blowing in gusts, strong typhoons, etc., and can effectively prevent the walking wheel from rolling left and right.

[0028] Specifically, when inserting the windproof locking rod 17, pulling the sliding column 201 can drive the pulling column 202 and the hollow block 203 and the disc baffle 204 above it to move together. At this time, the disc baffle 204 contacts the movable plate 207 and drives the movable plate 207 to move together. At the same time, the movable plate 207 contacts the V-shaped hollow cylinder 205, which will cause the movable plate 207 to move relatively and drive the clamping column 206 to move together, and the second spring 208 will be squeezed. When the windproof locking rod 17 is installed to the desired position, release the sliding column 201, and under the reset of the second spring 208, the entire thing will return to its original position. At this time, the clamping column 206 will engage with the clamping hole 209 above the cylinder 11, so that the windproof locking rod 17 can be firmly fixed and will not accidentally loosen and fall off.

[0029] Reference Figure 1 and Figure 2 The front end of the outer wall of the sliding column 201 is rotatably connected with a lock rod handle 18, and the outer wall of the lock rod handle 18 is provided with a lock rod connecting chain 19; the front top of the walking trolley 1 is fixedly connected with a cylinder 20, the lock rod connecting chain 19 is fixedly connected with the cylinder 20, and the right side of the top of the walking trolley 1 is fixedly connected with a windproof lock rod frame 21;

[0030] Specifically, the lock rod handle 18 can facilitate pulling the sliding column 201, the lock rod connecting chain 19 can prevent the windproof lock rod 17 from being lost, and the windproof lock rod frame 21 can store the windproof lock rod 17 when not in use.

[0031] Reference Figure 1 , Figure 2 and Figure 3 The front side of the top of the traveling trolley 1 is fixedly connected with a fixed column 22, and the outer wall of the fixed column 22 is rotatably connected with a semicircular rotating rod 23; the rear side of the top of the traveling trolley 1 is fixedly connected with a base 24, and the top of the base 24 is rotatably connected with a weather vane 25; the right side of the front end of the traveling trolley 1 is fixedly connected with a controller 26, and the controller 26 is electrically connected to the hydraulic rod 13; the outer side of the controller 26 is fixedly connected with a housing 27, and the outer side of the housing 27 is rotatably connected with a protective cover 28;

[0032] Specifically, the current wind speed can be known through the semicircular rotating rod 23, the current wind direction can be known through the wind vane 25, the starting and operating power of the hydraulic rod 13 can be controlled through the controller 26, the outer shell 27 can prevent the controller 26 from being damaged due to bumps, and the protective cover 28 can prevent dust and rain from entering the interior of the controller 26 and causing damage to its internal electronic components.

[0033] Working principle: Before using the device, first, in case of strong winds, in order to ensure the stability of the walking trolley, the windproof lock rod 17 is passed through the walking wheel hole 5 above the walking wheel 3, and the buckle position is appropriately adjusted to ensure its stability. Subsequently, the upper card plate positioning adjustment hole 10 and the lower card plate positioning adjustment hole 12 are respectively aligned and installed with the corresponding upper card plate positioning screw 9 and the lower card plate positioning bolt 8, and the nuts are tightened to firmly fix the card plate 7 and the arc baffle 6. At the same time, the hydraulic rod 13 is started to drive the moving block 14 to move toward the bottom of the walking trolley 1. During this process, the L-shaped clamping plate 15 is in an open state under the tension of the first spring 16. When the L-shaped clamping plate 15 contacts the fixed rail 4, as the hydraulic rod 13 continues to retract, the L-shaped clamping plate 15 will gradually clamp the fixed rail 4 until it is completely clamped. Through the above measures, the walking wheel 3 can be effectively prevented from rolling left and right due to wind blowing under severe weather conditions such as gusts and strong typhoons, thereby ensuring the stability and safety of the walking trolley.

[0034] And through the engaging and fixing mechanism 2, during the insertion process of the windproof lock rod 17, by pulling the sliding column 201, the pulling column 202 and the hollow block 203 above it and the disc baffle 204 can be linked to move in coordination. During this process, the disc baffle 204 forms contact with the movable plate 207, thereby driving the movable plate 207 to move synchronously. At the same time, the movable plate 207 interacts with the V-shaped hollow cylinder 205, so that the movable plate 207 is relatively displaced and drives the clamping column 206 to move together. During this process, the second spring 208 is compressed. When the windproof lock rod 17 is installed to the predetermined position, the pulling force on the sliding column 201 is released. At this time, the second spring 208 exerts its reset function to push the relevant components to return to the initial state. During this process, the clamping column 206 is engaged with the clamping hole 209 above the cylinder 11, thereby ensuring that the windproof lock rod 17 can be firmly fixed in the specified position and effectively preventing it from falling off due to accidental loosening.

[0035] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
