[0024] 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.

[0025] like Figure 1-2 As shown, a bridge crack surface repair glue 8 thickness measuring tool includes a fixed base 2, a dial indicator 5 is fixed to one side of the fixed base 2, the dial indicator 5 and the fixed base 2 are bonded or bolted, and the two ends of the fixed base 2 are connected to support legs 1, the lower end of the support leg 1 is flush with the lower end of the measuring head of the dial indicator 5, and the upper end of the fixed base 2 is provided with a handle 3.

[0026] The dial indicator 5 is a digital dial indicator 5, which can accurately read.

[0027] The lower end of the support leg 1 is covered with a detachable anti-skid cover 4, and the lower end surface of the anti-skid cover 4 is flush with the lower end of the measuring head of the dial indicator 5. The anti-skid cover 4 is directly covered on the lower end of the support leg 1. In order to ensure that the support leg 1 is flush with the lower end of the dial indicator 5, the anti-skid cover 4 is replaced in time when it is worn.

[0028] The outer side of the measuring rod of the dial gauge 5 is covered with a protective cover 6, and a clearance groove 601 is provided on the upper side wall of the protective cover 6. The protective cover 6 is rotatably connected to the fixing seat 2. Figure 3-4 As shown, a support block 201 is provided at the lower end of the fixing seat 2, and the protective cover 6 is connected to the support block 201 via a rotating shaft 602. The friction resistance between the rotating shaft 602 and the support block 201 prevents the protective cover 6 from rotating under the action of gravity after it is opened.

[0029] When measuring, the protective cover 6 rotates to one side. When not in use, the protective cover 6 shields and protects the measuring rod of the dial indicator 5 to avoid collision damage.

[0030] The maximum rotation angle of the protective cover 6 is 90°.

[0031] The fixing seat 2 is a cylindrical structure. Figure 5 As shown, the upper end of the supporting leg 1 is vertically connected with a slider 101, and the slider 101 is plugged into the fixing seat 2. The upper end of the slider 101 is provided with a long limiting groove 102, and the upper end of the fixing seat 2 is provided with a positioning bolt 7 that cooperates with the limiting groove 102. The positioning bolt 7 can not only prevent the slider 101 from escaping from the fixing seat 2, but also fix the slider 101.

[0032] like Figure 6 As shown, when in use, first, adjust the distance between the two supporting legs 1 to be greater than the width of the repair glue 8, open the protective cover 6, and press the measuring head of the dial indicator 5 on the upper end of the repair glue 8. The two supporting legs 1 are located on both sides of the repair glue 8, and push the handle 3 to make the supporting legs 1 contact with the bridge concrete on both sides of the repair glue 8. At this time, the reading of the dial indicator 5 is the thickness of the repair glue 8.

[0033] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
