[0028] Embodiment 1:

[0029] See also Figure 1 - Figure 3 As shown, a height limiting device for transportation includes:

[0030] A rod body 1, height limiting rods 11 are movably installed on both sides of the rod body 1, an extension rod 12 is movably installed inside the height limiting rod 11, and two identification plates 13 are movably installed outside the height limiting rod 11;

[0031] The lifting assembly 2 is arranged on both sides of the rod body 1. The lifting assembly 2 includes grooves 21 symmetrically opened on both sides of the rod body 1. A threaded rod 22 is movably installed inside the groove 21. A threaded block 23 is movably installed outside the threaded rod 22. One side of the threaded block 23 is fixedly connected to the height-limiting rod 11.

[0032] The fixing assembly 3 is arranged at one side of the top of the height limiting rod 11. The fixing assembly 3 includes two U-shaped frames 31 fixedly installed at the top of the height limiting rod 11. Bolts 32 are movably installed inside the two U-shaped frames 31. A plurality of threaded holes 33 are opened at the top of the extension rod 12;

[0033] The disassembly and assembly component 4 is arranged on one side of the height limit pole 11. The disassembly and assembly component 4 includes a mounting frame 41 fixedly installed on one side of the height limit pole 11. A mounting block 42 is movably installed inside the mounting frame 41. Two locking plates 45 are movably installed inside the mounting block 42. One side of the mounting block 42 is fixedly connected to the identification plate 13.

[0034] Specifically, grooves 21 are symmetrically provided on both sides of the rod body 1, and a threaded rod 22 is movably installed inside the groove 21 through a bearing, and a threaded block 23 is installed on the outer side of the threaded rod 22 through a threaded screw. The threaded block 23 slides and fits with the inner wall of the groove 21, and the threaded block 23 is fixedly connected to the height limiting rod 11 on the side away from the groove 21. Two servo motors 24 are installed on the top of the rod body 1 through a fixed seat, and the two servo motors 24 are respectively arranged corresponding to the two grooves 21. The output ends of the two servo motors 24 are connected to the shaft of the threaded rod 22 through a coupling. A rain shield 25 is fixedly installed on the top of the rod body 1, and the rain shield 25 is arranged outside the two servo motors 24.

[0035] As can be seen from the above, height limit rods 11 are respectively arranged on both sides of the rod body 1 to realize the height limit requirements for different lanes so that the height of the lanes on both sides can be limited. Threaded blocks 23 that can move up and down are respectively arranged inside the two grooves 21. The threaded rod 22 is used to drive the threaded block 23 to move to synchronously drive the height limit rod 11 to move up and down. The servo motor 24 provides power output for the rotation of the threaded rod 22, and the rain shield 25 can prevent rainwater from invading the inside of the servo motor 24.

[0036] Specifically, two U-shaped frames 31 are fixedly installed on the top of the height limiting rod 11 away from the rod body 1, and bolts 32 are installed inside the two U-shaped frames 31 through threaded engagement.

After the extension rod 12 is extended, the position of the extension rod 12 is locked to prevent the extension rod 12 from sliding inside the height limit rod 11, and also to prevent the extension rod 12 from escaping from the height limit rod 11 and falling onto the road, causing an impact on traffic.

[0038] Embodiment 2:

[0039] See also Figure 1 and Figure 4 - Figure 5 As shown, two mounting frames 41 are fixedly installed on one side of the height limit pole 11, and the two mounting frames 41 are arranged corresponding to the two identification plates 13. Mounting blocks 42 are movably installed inside the two mounting frames 41, and the mounting blocks 42 are slidably fitted with the inner walls of the mounting frames 41, and the top of the mounting blocks 42 is fixedly connected to one side of the identification plate 13.

[0040] Specifically, locking grooves 43 are symmetrically provided on both sides of the mounting block 42, and locking frames 44 are symmetrically provided on both sides of the mounting frame 41. The locking frames 44 are arranged corresponding to the locking grooves 43. A locking plate 45 is movably installed inside the locking frame 44 through a groove. One end of the locking plate 45 passes through the interior of the mounting frame 41, and the locking plate 45 extends into the locking groove 43 on the side close to the mounting block 42. An arc surface is provided on the side close to the locking groove 43 of the locking plate 45, and a reset plate 46 is fixedly installed on the outer side of the locking plate 45.

[0041] As can be seen from the above, a mounting frame 41 and a mounting block 42 are set on one side of the height limit pole 11, and the mounting block 42 is installed inside the mounting frame 41 to realize the rapid disassembly and assembly of the identification plate 13. At the same time, the mounting block 42 is locked by the cooperation of the locking plate 45 and the locking groove 43, thereby improving the stability of the installation of the identification plate 13. An arc surface is set on one side of the locking plate 45 to realize the rapid installation of the mounting block 42, and the reset plate 46 and the reset spring 47 can drive the locking plate 45 to complete the reset.

[0042] During specific use, the mounting block 42 is first pressed down along the inner wall of the mounting frame 41. During the pressing process, the edges of the mounting block 42 will first contact the arc surface of the locking plate 45, and then the locking plate 45 will move to both sides under the push of the mounting block 42. At this time, the reset spring 47 is in a compressed state until the mounting block 42 is pressed to the bottom of the mounting frame 41. At this time, the position of the locking plate 45 and the locking groove 43 just correspond to each other, and then the locking plate 45 will extend into the locking groove 43 under the action of the reset spring 47 to complete the locking of the mounting block 42.
