Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Referring to fig. 1, in an embodiment of the present invention, a height limiting device for a road and bridge building includes a height limiting rod 1, a first upright 2 is connected to one end of the height limiting rod 1, a second upright 10 is connected to the other end of the height limiting rod 1, a left pier 3 is disposed on the left side of the first upright 2, a right pier 13 is disposed on the right side of the second upright 10, a second hydraulic press 14 is disposed inside the right pier 13, a motor 12 is disposed above the second hydraulic press 14 and drives a screw rod 4 to rotate, scale marks 9 are disposed on the first upright 2 and the second upright 10, a height limiting rod chute 6 is disposed inside the height limiting rod 1, a first upright chute 8 is disposed inside the first upright 2, a second upright chute 7 is disposed inside the second upright 10, a slider 5 is disposed at a connection position between the height limiting rod 1 and the first upright 2 and the second upright 10, the slider 5 can move on the height limiting rod 1, the hydraulic machine can also slide on the first upright post 2 and the second upright post 10, a first hydraulic machine 4 is arranged inside the left pier body 3, a screw rod 11 is arranged inside the second upright post sliding groove 7, and the screw rod 4 can drive the height limiting rod 1 to move.
