Description

Technical Field

[0001] This utility model relates to the field of deflection testing instruments, and in particular to equipment for testing the deflection performance of bridge trusses. Background Technology

[0002] A bridge deflection meter is an instrument used to measure deflection. A deflection meter can measure the change in vertical distance from an object above it at any angle. It is mainly used for measuring the static and dynamic deflection of bridges, bridge completion acceptance and appraisal, inspection of special bridges such as military pontoon bridges and suspension bridges, deformation and vibration displacement monitoring of dams and wharves, or deformation and vibration displacement of beams and columns of large-span structures, high-rise buildings, lifting machinery, drilling platforms, etc.

[0003] Bridge deflection meters can also be used to test the deflection performance of bridge trusses. However, when using a deflection meter, since the monitoring of the bridge truss is outdoors, outdoor dust may accumulate on the lens of the deflection meter in a short period of time, affecting the normal operation of the meter and causing inaccurate results. This requires the testing personnel to stop the test and clean the lens with a cloth, thus interrupting the testing progress and making the meter inconvenient to use. Utility Model Content

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] This utility model provides, for example Figure 1-4 The bridge truss deflection performance testing equipment shown includes a deflection tester 1, a storage plate 3, a rotating plate 4, a cleaning plate 5, and a drive mechanism 6. The outer wall of the deflection tester 1 is equipped with a lens 2. The storage plate 3 is fixedly connected to the outer wall of the deflection tester 1. The cross-section of the storage plate 3 is L-shaped. The rotating plate 4 is rotatably positioned between the deflection tester 1 and the storage plate 3 via a rotating shaft. The cleaning plate 5 is set on the rotating plate 4. The cleaning plate 5 is made of sponge material. The sponge is soft and will not scratch the lens 2 of the deflection tester 1. It is also highly absorbent. If water splashes onto the lens 2 outdoors, it can be cleaned up as well. Its porous structure can effectively absorb dust. When rotating for cleaning, it can wipe away dirt from the surface of the lens 3 from all directions. It is reusable and easy to disassemble and clean, ensuring that each cleaning is clean and effective. The drive mechanism 6 is located inside the storage plate 3 and is used to drive the rotating plate 4 to rotate. When not in use, the entire deflection detector 1 can be stored in a special storage box to avoid dust accumulation. However, when in use, because the bridge is an open ground, it will get dusty at any time, affecting its use. Therefore, the cleaning plate 5 can be driven by the drive mechanism 6 for cleaning.

[0032] Specifically, the drive mechanism 6 includes a gear 61, a rack 62, and a pulling component 63. The outer wall of the rotating plate 4 has a groove, and the gear 61 is located inside the groove. The gear 61 is fixedly inserted and connected to the rotating shaft. The rack 62 is located inside the storage plate 3 and meshes with the gear 61. The pulling component 63 is located inside the storage plate 3 and is used to pull the rack 62 to move. The pulling component 63 can drive the rack 62 to slide in the horizontal direction, so that the rack 62 can drive the gear 61 to rotate 180°. This can drive the cleaning plate 5 on the rotating plate 4 to rotate through the rotating shaft, and clean the lens 2 during the rotation.

[0033] Furthermore, the pulling assembly 63 includes a slider 631, a pull rod 632, a compression spring 633, and a pull plate 634. A groove is provided at the bottom end of the storage plate 3. The slider 631 is fixedly connected to the bottom end of the rack 62, and the slider 631 is slidably inserted into the inner cavity of the groove. One end of the pull rod 632 is fixedly connected to the slider 631, and the other end of the pull rod 632 is slidably inserted into the storage plate 3. The compression spring 633 is sleeved on the outside of the pull rod 632, with one end fixedly connected to the slider 631 and the other end fixedly connected to the slider 631. The compression spring 633 is always in a compressed state, thereby lifting the slider 631. A stable elastic force is provided so that, without the influence of external force, the rack 62 on the slider 631 can keep the rotating plate 4 connected to the gear 61 in a horizontal state. At this time, the rotating plate 4 is horizontally stored inside the storage plate 3, which will not affect the normal use of the lens 2. Moreover, after each pull of the lever 632, it can be reset under the elastic force of the compression spring 633, which is convenient to use. The end of the lever 632 is fixedly connected to the pull plate 634. The outer wall of the pull plate 634 is symmetrically provided with arc-shaped grooves. The arc-shaped grooves make it convenient for the operator to pull the lever 632 by inserting their fingers into the arc-shaped grooves and then pulling the lever 632 through the pull plate 634, which is convenient to use.

[0034] Furthermore, a mounting block 7 is fixedly connected to the outer wall of the cleaning plate 5, and an installation groove is provided on the inner wall of the rotating plate 4. The mounting block 7 is slidably inserted into the inner cavity of the installation groove. The cross-section of the mounting block 7 is T-shaped. A positioning hole is provided on the outer wall of the rotating plate 4, and a bolt 8 is threadedly inserted into the inner cavity of the positioning hole to restrict the sliding of the mounting block 7. The T-shaped mounting block 7 ensures that after the cleaning plate 5 is installed inside the installation groove, it can only be removed by sliding out of the installation groove. The installation position of the bolt 8 is exactly in contact with the outer wall of the mounting block 7, thereby restricting the sliding of the mounting block 7 inside the installation groove. This allows the cleaning plate 5 to be stably installed inside the rotating plate 4, and it is also convenient to disassemble. Only the installation of this one bolt 8 needs to be removed, and the dirty cleaning plate 5 can be taken out through the mounting block 7 and replaced with a new cleaning plate 5, which is convenient for use.

[0035] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
