DETAILED DESCRIPTION

The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

As shown in Figures 1 to 4, a verticality detection device for bridge construction includes a base 1 and a column 8. Four movable supporting feet 2 are arranged at the bottom of the base 1. The movable supporting feet 2 are arranged to slide vertically with the base 1, and a first adjusting member 3 is arranged between the movable supporting feet 2 and the base 1. Level meters 12 are arranged on all sides of the base 1. The column 8 is arranged vertically with the base 1, and a mounting rod 5 is arranged on one side of the column 8. The mounting rod 5 is arranged parallel to the column 8, and two sliding rods 11 penetrating the column 8 are arranged on the mounting rod 5. A second adjusting member for adjusting the mounting rod 5 relative to the column 8 is arranged on the column 8. A level ruler 4 is slidably arranged at both upper and lower ends of the mounting rod 5. The end of the level ruler 4 away from the column 8 is a pointed structure, and a pressing member 6 for pre-tightening the level ruler 4 is arranged on the mounting rod 5.

The first adjusting member 3 includes a first adjusting bolt 15 and a first nut 14. One end of the movable supporting foot 2 is provided with a limiting portion 13 that cooperates with the base 1. One end of the first adjusting bolt 15 passes through the base 1 and is threadedly connected to the limiting portion 13. The first nut 14 is threadedly connected to the first adjusting bolt 15 and provides support for the base 1. When the movable supporting foot 2 is unevenly in contact with the ground, the first adjusting bolt 15 is adjusted by turning the knob. At this time, the movable supporting foot 2 cannot rotate under the limitation of the limiting portion 13, and the length of the first adjusting bolt 15 screwed into the movable supporting foot 2 changes. In this way, the height of the first nut 14 also changes, so that the height of a certain vertex angle of the base 1 can be adjusted. By observing the level ruler 4, it is ensured that the top surface of the base 1 is in a horizontal state and the column 8 is in a vertical state.

The second adjusting member includes a first spring 9, a second adjusting bolt 10 and a second nut 21. Two of the first spring 9 and the second nut 21 are provided. The second nut 21 is threadedly connected to one end of the sliding rod 11 passing through the column 8. The first spring 9 is sleeved on the sliding rod 11 and exerts a force on the mounting rod 5 to approach the column 8. When it is necessary to use the level 4 to measure the verticality of the bridge, by rotating the second adjusting bolt 10, one end of the second adjusting bolt 10 is pushed away from the column 8, so that the mounting rod 5 can drive the level 4 to move and approach the side wall of the bridge, thereby completing the verticality measurement of the bridge.

The pressure piece 6 includes a limit bolt 17, a third nut 18 and a second spring 16. A recess 20 is provided at the position of the mounting rod 5 corresponding to the level 4. One end of the limit bolt 17 passes through the mounting rod 5 and extends into the recess 20. The third nut 18 is threadedly connected to the limit bolt 17. The second spring 16 is located in the recess 20 and applies a force to the limit bolt 17 to resist the level 4. During the verticality measurement process, when the two levels 4 hit the side wall of the bridge and then the base 1 is removed, the level 4 will not shake easily and the readings of the two levels 4 will not be disturbed, so as to ensure the accuracy of the verticality measurement data.

A limit block 7 is provided at one end of the level 4 close to the column 8, and two pins 19 are provided between the limit block 7 and the level 4. The limit block 7 can be provided to push the level 4 in a direction away from the column 8 so that the reading of the level 4 returns to zero, thereby making it convenient to measure the verticality of the bridge.

Working principle: The device is placed at the position of the bridge to be tested, and the base 1 is separated from the ground by four movable supporting feet 2. When the ground is uneven, the height of a certain top angle of the base 1 is adjusted by the first adjusting member 3, and the level 12 is combined to ensure that the top surface of the base 1 is in a horizontal state, so that the column 8 remains vertical, and then the reading of the level 4 is reset to zero, and then the second adjusting bolt 10 is turned to make the second adjusting bolt 10 push the mounting rod 5 and the level 4 to move horizontally until one end of the two levels 4 both touch the side wall of the bridge. Combined with the length difference of the other ends of the two levels 4 extending out of the mounting rod 5 and the height difference of the two levels 4, the inclination angle of the side wall of the bridge can be calculated, and it can be determined whether the verticality of the bridge meets the requirements.
