[0043] As shown in Figure 3 , the limiting assembly 2 is arranged in the mounting seat 1 and comprises a bottom plate 21, a first vertical plate 23, a limiting block 24 and a second vertical plate 25. The bottom plate 21 is horizontally placed in the mounting seat 1, the bottom plate 21 is provided with a protruding portion 22 near a top portion of a middle portion of the mounting seat 1, the first vertical plate 23 is welded to one side of the bottom plate 21 away from the protruding portion 22, the first vertical plate 23 is vertically arranged, and the limiting block 24 is detachably arranged on an upper portion of one side of the first vertical plate 23 near the protruding portion 22.

[0044] In the embodiment of the present application, the thickness of the protruding portion 22 near one side of the first vertical plate 23 is smaller than the thickness of the protruding portion 22 away from the first vertical plate 23. When the stand rod 3 is inserted into the mounting seat 1 and continues to move, the protruding portion 22 can be in contact with the bottom of the stand rod 3, and the slope surface of the protruding portion 22 can drive the bottom plate 21 to move when the stand rod 3 continues to move, so as to drive the limiting block 24 to approach the stand rod 3 and limit the position of the stand rod 3.

[0045] In the embodiment of the present application, the limiting block 24 is a metal quadrangular prism, and the limiting block 24 is arranged on the outer wall slope surface of the top and the bottom. The limiting block 24 is provided with a through hole, and the limiting block 24 is threadedly connected with the first vertical plate 23 through the bolt inserted into the through hole 31. The limiting block 24 is detachably connected with the first vertical plate 23 through the bolt inserted into the through hole 31, so as to facilitate the removal of the limitation of the position of the stand rod 3 when the stand rod 3 needs to be replaced.

[0046] In the embodiment of the present application, the second vertical plate 25 is vertically arranged on the side of the bottom plate 21 near the protruding portion 22, and the second vertical plate 25 is welded with the bottom plate 21.

[0049] Specifically, when the upright pole 3 needs to be installed, the construction personnel can place two limiting assemblies 2 in the mounting seat 1, and insert the upright pole 3 into the mounting seat 1 through the insertion hole 11. When the upright pole 3 is inserted into the mounting seat 1 and continues to move, the protruding part 22 can be in contact with the bottom of the upright pole 3, and the slope surface of the protruding part 22 can drive the bottom plate 21 to move when the upright pole 3 continues to move, so as to drive the limiting block 24 to be inserted into the through hole 31 of the upright pole 3, and limit the position of the upright pole 3. When the upright pole 3 has a tendency to move upward, the first vertical plate 23 abuts against the inner wall of the top of the mounting seat 1, so as to limit the tendency of the upright pole 3 to move upward through the limiting block 24. When the upright pole 3 moves upward without the limiting block 24 being removed, after the first vertical plate 23 abuts against the inner wall of the top of the mounting seat 1, the limiting assembly 2 has a tendency to rotate toward the inside of the mounting seat 1 with the limiting block 24 as the axis. At this time, the two second vertical plates 25 abut against each other, which can limit the tendency of the two limiting assemblies 2 to rotate, and ensure that the two first vertical plates 23 can abut against the inner wall of the top of the mounting seat 1.

[0050] When the upright pole 3 needs to be replaced individually, the limiting block 24 inserted into the upright pole 3 through the through hole 31 can be removed through the maintenance hand hole 32, so as to release the limitation on the position of the upright pole 3, thereby enabling the construction personnel to pull out the upright pole 3 from the mounting seat 1 and replace the upright pole 3, and improving the problem that the existing gantry cannot replace the upright pole 3 individually.

The hand hole cover 33 can protect the structure inside the upright pole 3 from the influence of the external environment during non-maintenance period, such as preventing the invasion of moisture, dust and other impurities, thereby prolonging the service life of the upright pole 3.

[0053] As Figure 5As shown, the cross frame 4 includes a first cross bar 41, a second cross bar 42 and a height limiting bar 46, the first cross bar 41 is horizontally arranged, two ends of the first cross bar 41 are respectively detachably connected with the two vertical rods 3 through bolts, the first cross bar 41 is detachably connected with the signboard 43 through bolts, the second cross bar 42 is horizontally arranged, two ends of the second cross bar 42 are respectively detachably connected with the two vertical rods 3 through bolts, the second cross bar 42 is located below the first cross bar 41, and the second cross bar 42 is detachably connected with the LED display screen 44 through bolts; the first cross bar 41 and the second cross bar 42 bring flexibility and versatility to the installation and use of the cross frame 4, the first cross bar 41 or the second cross bar 42 can be detached alone, and the maintenance and replacement process is simplified; the detachable connection of the first cross bar 41 and the signboard 43 enables the signboard 43 to be quickly replaced or updated according to different traffic needs; the detachable connection of the second cross bar 42 and the LED display screen 44 also provides convenience for maintenance and replacement.

[0054] The detachable connection design of the cross frame 4 and the vertical rod 3 facilitates the retention of the cross frame 4 when the vertical rod 3 is replaced, and the signboard 43 and the LED display screen 44 arranged on the cross frame 4 can provide more rich and dynamic traffic information; it should be noted that the model of the LED display screen 44 in the embodiment of the application needs to be set according to the actual construction situation, and the model of the LED display screen 44 is not specifically limited in the application; for the convenience of understanding, the LED display screen 44 in the embodiment of the application includes but is not limited to the LED display screen 44 of the SID-005 solar traffic warning LED radar speed display sign screen.

[0055] The height limiting bar 46 is detachably suspended below the second cross bar 42 through a plurality of suspension cables 45, the height limiting bar 46 can quickly adjust the position or height of the height limiting bar 46 through the suspension cables 45 according to the needs of traffic management, so as to adapt to different traffic conditions or the passing needs of special vehicles, and by adjusting the height limiting bar 46, the passage of vehicles with excessive height through a specific road section can be prevented, and the damage to road facilities can be reduced.

[0056] Specifically, when the vertical rod needs to be replaced, the first cross bar 41 and the second cross bar 42 can be detached without detaching the signboard 43 on the first cross bar 41, the LED display screen 44 on the second cross bar 42 and the height limiting bar 46 on the second cross bar 42; after the replacement of the vertical rod is completed, the detached first cross bar 41 and the second cross bar 42 are reinstalled on the newly replaced vertical rod, which not only improves the problem that the existing gantry cannot replace the vertical rod 3 alone, but also reduces the maintenance cost and reduces the occurrence of long-term traffic interruption, ensuring the normal use of the road.

[0057] The above are all preferred embodiments of the present application, and do not limit the protection scope of the present application, so that: all equivalent changes made according to the structure, shape, principle of the present application should be covered in the protection scope of the present application.
