Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention.

The invention comprises a main steel pipe 1, wherein the main steel pipe 1 is fixed on a steel pipe base. The steel tube base comprises a bottom steel tube 2, and the bottom of the main body steel tube 1 is inserted in the bottom steel tube 2. Preferably, bolt holes are formed in the side surface of the bottom steel pipe 2, and the bottom steel pipe 2 and the main steel pipe 1 are more firmly fixed together by bolts penetrating through the bolt holes.

The main steel pipe 1 is sleeved with a connecting piece 3, and the connecting piece 3 is used for connecting an internal steel frame structure of a bridge and is a known piece, and the description is omitted here. The connecting piece 3 can move up and down along the main body steel pipe 1, and the inner diameter of the connecting piece 3 is slightly larger than the outer diameter of the main body steel pipe 1. All be equipped with ring 4 from top to bottom at connecting piece 3, the equal fixed connection annular handle 5 of 4 outer walls of ring, 4 inner walls of ring are equipped with the internal thread. Vertical bar grooves are symmetrically formed in the side wall of the main steel pipe 1, threaded bars 6 are fixed in the vertical bar grooves, external threads matched with the internal threads of the circular ring 4 are arranged on the outer surfaces of the threaded bars 6, and the circular ring 4 is connected with the main steel pipe 1 in a threaded mode. The ring-shaped handle 5 is rotated to move the ring 4 upwards or downwards, and the middle connecting piece 3 can move upwards and downwards along with the ring-shaped handle. When the connecting piece 3 reaches the required height, the connecting piece 3 is tightly clamped between the upper ring and the lower ring by rotating the upper ring 4 and the lower ring 4, so that the height of the connecting piece 3 is adjusted and the connecting piece 3 is fixed.
