Description

Technical Field

[0001] The present application relates to the technical field of bridge detection devices, and in particular to a non-destructive detection device for bridges. Background Art

[0002] Nondestructive testing technology, also known as non-destructive testing, is an inspection method used to obtain physical and chemical information such as content, properties or components related to the quality of the object to be tested without destroying the original state and chemical properties of the object to be tested. Nondestructive testing uses the sound, light, magnetism and electricity characteristics of the material to detect whether there are defects or unevenness in the object to be tested, and provide information such as defect size, location, nature and quantity without damaging or affecting the performance of the object to be tested.

[0003] In order to ensure the quality of the bridge and the pass rate in many aspects, after the bridge deck inspection is completed, staff are required to take a ladder and carry the inspection equipment to conduct inspections at the bottom of the bridge. During the inspection process, the staff needs to hold the inspection reference instrument in one hand and the inspection head in the other hand and attach it to the bridge deck. When checking the data, the staff needs to hold the inspection head up for a long time, which not only consumes physical strength, but also when changing the inspection position, the distance is close and the staff cannot reach it, so the position of the ladder needs to be adjusted, which is more troublesome.

[0019] The following is combined with Figure 1-Figure 3 This application is described in further detail.

[0020] The present application embodiment discloses a bridge nondestructive testing device. Figure 1-Figure 3 A bridge nondestructive testing device includes a detector body 1 and a detection head body 2, the detector body 1 and the detection head body 2 are connected by a long wire, a pair of connecting plates 3 are fixed on the detection head body 2 using screws, both connecting plates 3 are provided with fixing holes 10, and the notches 10 are provided with chamfers 18; it also includes an auxiliary mechanism, the auxiliary mechanism includes a No. 1 plate 4, a No. 2 plate 5 and a connecting assembly that are connected and fixed, and the connecting assembly is used to connect and fix the connecting plate 3 and the No. 1 plate 4; a fixing rod 6 is fixed on the No. 2 plate 5, a sleeve rod 8 is sleeved on the fixing rod 6, and the fixing rod 6 is slidably connected to the sleeve rod 8.

[0021] The connecting assembly includes a movable plate 16, a pair of extension plates 11 are fixed on the No. 1 plate 4, a neutral plate 15 is fixed between the two extension plates 11, a support pole 13 is fixed between the neutral plate 15 and the extension plate 11, a spring 14 is sleeved on the outer side of the support pole 13, the movable plate 16 is sleeved on the support pole 13, the spring 14 is respectively connected to the neutral plate 15 and the movable plate 16, the two connecting plates 3 are respectively connected to the extension plates 11, the two movable plates 16 can move closer to or away from each other, a fixed column 12 is fixed on the movable plate 16, the fixed column 12 is adapted to the fixed hole 10, a corresponding hole 20 adapted to the fixed column 12 is opened on the extension plate 11, a pair of rectangular long holes 21 are opened on the No. 1 plate 4, and an operating plate 19 is fixed on the side of the two movable plates 16 facing the rectangular long holes 21.

[0022] During installation, take the detection head body 2, and use two fingers of the other hand to pinch the operating plate 19 respectively, so that the two movable plates 16 are close to each other. At this time, the spring 14 is compressed, and the fixing column 12 is located between the two extension plates 11, so that the two connecting plates 3 are moved on the two extension plates 11. When the fixing hole 10 is aligned with the corresponding hole 20, the operating plate 19 is released. At this time, the two movable plates 16 are pushed away from each other according to the elastic reset force of the spring 14, and the fixing column 12 is inserted into the fixing hole 10 respectively, and the installation is completed. Because the fixing column 12 is a cylinder, the detection head body 2 can be rotated on the No. 1 plate 4, so that it fits more closely on the bridge deck, which facilitates detection.

[0023] In this embodiment, if Figure 1 As shown, an adjusting bolt 7 is screwed on one end of the sleeve rod 8 close to the fixed rod 6, and the adjusting bolt 7 is connected to the fixed rod 6. This arrangement can facilitate length adjustment as needed, so that the detection head body 2 can change the detection position, and can avoid small-amplitude displacement of the ladder, which is convenient and quick. During the detection process, pick up the sleeve rod 8 to make the detection head body 2 fit the bridge deck.

[0024] In this embodiment, if Figure 2 As shown, it also includes guide rods 17. Two guide rods 17 are fixed on the extension plate 11. The two guide rods 17 slide through the movable plate 16. The guide rods 17 can enable the movable plate 16 to move on the same straight line to avoid position deviation caused by rotation, so that the fixed column 12 and the corresponding hole 20 are misaligned, and the practicality is high.

[0025] In this embodiment, if Figure 1 As shown, an L-shaped plate 9 is fixed on the sleeve rod 8. When the inspection is completed, the L-shaped plate 9 can be hung on the ladder guardrail, thereby saving manpower.

[0026] The implementation principle of a bridge nondestructive testing device in an embodiment of the present application is as follows: during installation, take the test head body 2, and use two fingers of the other hand to pinch the operating plate 19 respectively, so that the two movable plates 16 can be moved closer to each other. At this time, the spring 14 is compressed, and the fixing column 12 is located between the two extension plates 11, so that the two connecting plates 3 are moved on the two extension plates 11. When the fixing hole 10 is aligned with the corresponding hole 20, the operating plate 19 is released. At this time, the two movable plates 16 are pushed away from each other according to the elastic reset force of the spring 14, and the fixing column 12 is inserted into the fixing hole 10 respectively, and the installation is completed. Because the fixing column 12 is a cylinder, the test head body 2 can be rotated on the No. 1 plate 4, so that it fits more closely on the bridge deck, which facilitates detection.
