[0027] refer to Figure 2 The left and right sides of the inner wall of the fixed box 3 and the positions corresponding to the slider 51 are both provided with slide grooves 6 , and the slide grooves 6 are used in conjunction with the slider 51 .

[0028] As a technical optimization solution of the present invention, the slide 51 can be moved up and down in the slide 6 by setting the slide 6, and at the same time play a role of limiting, thereby avoiding the phenomenon of displacement of the slide 51 during the movement.

[0029] refer to Figure 2 An oblique groove 7 is provided at the front end of the connecting plate 53 and corresponds to the position of the transmission rod 57 , and the oblique groove 7 is used in conjunction with the transmission rod 57 .

[0030] As a technical optimization solution of the present invention, the oblique groove 7 is provided to enable the transmission rod 57 to move inside the oblique groove 7 and at the same time play a limiting role, thereby avoiding the transmission rod 57 from being separated during the movement.

[0031] refer to Figure 2 A limiting ring 8 is fixedly sleeved on the surface of the forward and reverse screws 54 and located on the inner side of the shaft sleeve 56 , and the limiting ring 8 is used in conjunction with the shaft sleeve 56 .

[0032] As a technical optimization solution of the present invention, the setting of the limit ring 8 can assist the shaft sleeve 56 in working and play a protective role at the same time, thereby avoiding the phenomenon of collision caused by the shaft sleeve 56 moving beyond the distance.

[0037] The working principle and use process of the utility model are as follows: when in use, the material is placed on the top of the fixed box 3, and then the handle 55 is manually rotated clockwise. The rotation of the handle 55 drives the forward and reverse screws 54 to rotate. The forward and reverse screws 54 rotate to cooperate with the internal threads of the shaft sleeve 56 to be screwed inward. The movement of the shaft sleeve 56 drives the transmission rod 57 to follow the movement. The movement of the transmission rod 57 cooperates with the oblique groove 7 to force the connecting plate 53 to move upward. The upward movement of the connecting plate 53 drives the limit frame 52 and the slider 51 to move synchronously. The slider 51 cooperates with the slide groove 6 to move upward stably until the limit frame 52 extends out of the top of the fixed box 3 through the rectangular opening 9 to circle and limit the material.

[0038] To sum up: the steel structure rigidity detection device for water conservancy bridge construction, through the cooperation of testing machine 1, support platform 2, fixing box 3, press machine 4, limiting mechanism 5, slider 51, limiting frame 52, connecting plate 53, forward and reverse screws 54, turning handle 55, bushing 56 and transmission rod 57, solves the problem that the existing steel structure detection equipment cannot limit the material during operation, resulting in the material being easily squeezed and ejected during the test.
