Description

Technical Field

[0001] This utility model relates to the field of measuring devices, and in particular to a measuring device for the height difference between expansion joints and bridge decks. Background Technology

[0002] Current technology for detecting the height difference between bridge expansion joints and the bridge deck typically uses a traditional 3-meter straightedge placed above the expansion joint. Inspectors squat beside the straightedge and manually observe the point with the largest gap below it, then use a feeler gauge to verify each gap and find the lowest point. This is then used as the test data for the height difference between the expansion joint and the bridge deck. However, relying on manual observation of the gap between the straightedge and the ground to determine the height difference is difficult, and since bridge decks are usually open to traffic, the inspection process often carries high safety risks. This results in low inspection efficiency and significant safety risks. Utility Model Content

[0023] This embodiment provides a measuring device for the height difference between an expansion joint and a bridge deck, including a ruler 1 and several movable feeler gauges 2. The movable feeler gauges 2 are movably connected to the ruler 1 and are perpendicular to the ruler 1. The several movable feelers are arranged parallel to each other along the scale 24 of the ruler 1.

[0024] like Figure 1 , Figure 3 As shown, the movable feeler gauge 2 extends into the first side surface 12 of the ruler 1 and extends out from the second side surface 13. The movable feeler gauge 2 can extend and retract on both sides of the ruler 1. The end of the movable feeler gauge 2 that extends out from the second side surface 13 is provided with a scale 24.

[0025] When one end of the movable feeler gauge 2 is aligned with the first side surface 12 of the ruler 1, the 0 mark 24 line on the end of the movable feeler gauge 2 with the scale 24 is aligned with the second side surface 13 of the ruler 1.

[0026] When in use, ruler 1 is placed along the bridge direction on the expansion joint of the bridge deck (ruler 1 is parallel to the expansion joint), with both ends of ruler 1 on the bridge deck and the middle part on the expansion joint. The end of the movable feeler gauge 2 without the scale 24 touches the ground. The movable feeler gauge 2 is aligned with the first side surface 12 of ruler 1 and touches the ground, indicating that the point is horizontal. The 0 mark 24 line of the movable feeler gauge 2 at this point is aligned with the second side surface 13 of ruler 1. If the first side surface 12 is suspended, one end of the movable feeler gauge 2 will still touch the ground due to gravity. The length of the movable feeler gauge 2 extending from the first side surface 12 of ruler 1 represents the height difference between the expansion joint and the bridge deck at that point. The scale 24 line on the other end of the movable feeler gauge 2 is aligned with the second side surface 13. The scale 24 corresponding to this line represents the height difference between the expansion joint and the bridge deck at that point. Example 2

[0027] like Figure 1 , Figure 2 As shown, the difference between this embodiment and the previous embodiment is that: a through hole 11 for installing a movable feeler gauge 2 is provided on the ruler 1. The through hole 11 extends from the first side surface 12 to the second side surface 13. Several through holes 11 are equidistantly distributed on the ruler 1. When the movable feeler gauge 2 is placed in the through hole 11, both ends can be extended and retracted.

[0028] Ruler 1 is made of 3-meter aluminum alloy.

[0029] like Figure 3 , Figure 4 As shown, the movable feeler gauge 2 includes an end cap 21, a straight section 22, and a triangular cone 22. The end cap 21 and the triangular cone 22 are detachably mounted on both ends of the straight section 22. The detachable end cap 21 and triangular cone 22 prevent the movable feeler gauge 2 from sliding out of the through hole 11 of the straight ruler 1. The detachable mounting also makes it easy to remove the movable feeler gauge from the straight ruler 1. If a single movable feeler gauge 2 is damaged during use, it can be removed and replaced. All movable feeler gauges 2 can also be removed for cleaning.

[0030] When in use, the pointed end of the triangular pyramid 22 contacts the ground, and the width of the end connected to the ruler section 22 is greater than that of the ruler section 22. The end cap 21 has a cuboid structure and its width is greater than that of the ruler section 22.

[0031] The ruler section 22 is a cuboid structure with a width of 1 cm. A scale 24 is provided on the ruler section 22. The 0 mark of the scale 24 is located on the ruler section 22. The length between the triangular pyramid 22 and the 0 mark is the same as the width of the ruler 1. The scale 24 extends towards the end cap 21. The accuracy of the scale 24 is 1 mm.

[0032] In use, ruler 1 is placed above the expansion joint along the bridge direction, with its first side surface 12 close to the ground. Personnel observe the height of the movable feeler gauge 2. The mark 24 on the scale where the movable feeler gauge 2 aligns with the second side surface 13 of ruler 1 represents the bridge deck height difference. Workers read and record the data from mark 24 on the movable feeler gauge 2 on ruler 1. This embodiment has a simple structure, can quickly measure the height difference between the expansion joint and the bridge deck, and is easy to operate.

[0033] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
