The upper surface of the measuring device 03 is fixedly connected with a chuck 611. Through the arrangement of the first fixing rod 601, the fixing hole 602, the positioning rod 603, the positioning hole 604, the first spring 605, the first stopper 606, the bayonet 607, the second fixing rod 608, the second stopper 609, the compression spring 610 and the chuck 611, the height of the chuck 611 can be adjusted according to the size of the object to be measured. When adjustment is required, the first stopper 606 is pulled to make the first spring 605 pull the bayonet 607 out of the fixing hole 604. , the compression spring 610 slowly relaxes and moves upward on the surface of the second fixing rod 608, thereby driving the chuck 611 to move upward. When it moves to the highest position, the second stopper 609 will resist the chuck 611, so that the chuck 611 stops moving upward. At this time, the first stopper 606 is released, and the first spring 605 will bounce the pin 607 into the positioning hole 604, thereby completing the height positioning of the chuck 611. In this process, there is no need for manual measurement to adjust the chuck 611, which greatly reduces the error caused by manual labor.

[0022] Furthermore, the pushing mechanism 5 includes a first slide groove 501, a second slide groove 502, a slider 503, a first moving block 504, a gasket 505, a threaded rod 506, a fixed block 507 and a hand crank 508. The inner wall surface of the base 2 is provided with a first slide groove 501, and the inner wall surfaces at both ends of the base 2 are provided with second slide grooves 502. The bottom surface of the support plate 4 is fixedly connected with the slider 503, the inner wall surface of the first slide groove 501 is slidably connected with the first moving block 504, one end surface of the first moving block 504 is fixedly connected with the gasket 505, one end surface of the gasket 505 is fixedly connected with the threaded rod 506, one end surface of the threaded rod 506 is fixedly connected with the fixed block 507, and the inner wall surface of the fixed block 507 is slidably connected with the hand crank The rocker 508 is arranged through the first slide groove 501, the second slide groove 502, the slider 503, the first moving block 504, the gasket 505, the threaded rod 506, the fixed block 507 and the hand rocker 508. When the object to be measured is placed on the workbench 3, the hand rocker 508 on the inner wall of the fixed block 507 is rotated to make the threaded rod 506 push the first moving block 504 to move in the first slide groove 501, and at the same time, the slider 503 fixedly connected to the first moving block 504 moves in the second slide groove 502, thereby completing the adjustment of the position of the support plate 4. In this process, the gasket 505 is made of silicone material, which can increase the friction between the threaded rod 506 and the first moving block 504, and at the same time, it can also preserve the integrity of the contact surface between the threaded rod 506 and the first moving block 504.

[0023] Furthermore, the inner wall size of the first slide groove 501 is consistent with the outer wall size of the first movable block 504, and the hand crank 508 and the threaded rod 506 cooperate with each other to form a rotating structure. Through the setting of the first slide groove 501, the first movable block 504, the threaded rod 506 and the hand crank 508, the first slide groove 501 limits the first movable block 504, so that the first movable block 504 can move more smoothly when the hand crank 508 shakes the threaded rod 506.

[0024] Furthermore, the outer wall size of the pin 607 is consistent with the inner wall size of the fixing hole 602, and multiple groups of positioning holes 604 are arranged on the surface of the positioning rod 603. Through the arrangement of the fixing hole 602, the positioning rod 603, the positioning hole 604 and the pin 607, the fixing hole 602 limits the pin 607, so that the positioning rod 603 will not slide when being fixed on the inner wall of the first fixing rod 601. The arrangement of multiple groups of positioning holes 604 can quickly position the height of the chuck 611.

[0025] Furthermore, the limiting mechanism 7 includes a moving groove 701, an adjusting hole 702, a limiting plate 703, a second moving block 704, a clamping hole 705, a second spring 706 and a limiting block 707. The inner wall surface of the workbench 3 is provided with a moving groove 701, the inner wall surface of the moving groove 701 is provided with an adjusting hole 702, the upper surface of the workbench 3 is slidably connected to the limiting plate 703, the bottom surface of the limiting plate 703 is fixedly connected to the second moving block 704, the bottom surface of the second moving block 704 is provided with a clamping hole 705, the outer wall surface of the clamping hole 705 is fixedly connected to the second spring 706, one end surface of the second spring 706 is fixedly connected to the limiting block 707, and the moving groove 701, the adjusting hole 702, the limiting plate 701 and the limiting block 707 are connected to the workbench 3. 03. With the arrangement of the second moving block 704, the clamping hole 705, the second spring 706 and the limit block 707, when an object is placed on the workbench 3, it may slide left and right or forward and backward due to the uneven terrain. At this time, the distance between the limit plates 703 can be adjusted according to the size of the object, and the limit plates 703 are moved so that the second moving block 704 drives the limit plates 703 to move in the moving groove 701. The second spring 706 will bring the limit block 707 into the clamping hole 705 under the action of force. When it moves to a suitable position, the clamping hole 705 is aligned with the adjustment hole 702, and the second spring 706 will bounce the limit block 707 into the adjustment hole 702 to fix the limit plate 703, and at the same time clamp the object without shaking.

[0026] Furthermore, multiple groups of adjustment holes 702 are arranged on the inner wall surface of the movable groove 701, and two groups of limit plates 703 are symmetrically arranged around the central axis of the workbench 3. Through the arrangement of the movable groove 701, the adjustment holes 702 and the limit plates 703, the position of the limit plates 703 can be quickly adjusted.

[0027] Working principle: first, when the object to be measured is placed on the workbench 3, the hand crank 508 on the inner wall of the fixed block 507 is rotated to make the threaded rod 506 push the first moving block 504 to move in the first slide groove 501, and at the same time, the slider 503 fixedly connected to the first moving block 504 moves in the second slide groove 502, thereby completing the adjustment of the position of the support plate 4. In this process, the gasket 505 is made of silicone material, which can increase the friction between the gasket 505 and the threaded rod 506, and at the same time, it can also preserve the integrity of the contact surface between the threaded rod 506 and the first moving block 504. Secondly, the height of the chuck 611 can be adjusted according to the size of the object to be measured. When adjustment is required, the first stopper 606 is pulled to make the first spring 605 pull the bayonet 607 out of the fixing hole 604, and the compression spring 610 is slowly relaxed and moved upward on the surface of the second fixed rod 608, thereby driving the chuck 611 to move upward. When it moves to the highest position, the second stopper 609 will resist the chuck 611, so that the chuck 611 stops The first spring 705 will push the stopper 707 into the positioning hole 604 to complete the height positioning of the clamp 611. In this process, there is no need to manually adjust the clamp 611, which greatly reduces the error caused by manual operation. When the object is placed on the workbench 3, it may slide left and right or forward and backward due to uneven terrain. At this time, the distance between the limit plates 703 can be adjusted according to the size of the object. The limit plate 703 is moved so that the second moving block 704 drives the limit plate 703 to move in the moving groove 701. The second spring 706 will bring the limit block 707 into the clamping hole 705 under the action of force. When it moves to a suitable position, the clamping hole 705 is aligned with the adjusting hole 702, and the second spring 706 will push the limit block 707 into the adjusting hole 702 to fix the limit plate 703. At the same time, the object is clamped and there will be no shaking. This completes the use process of the inspection tool for the bridge support.
