Description

Technical Field

[0001] This utility model relates to the field of engineering measurement technology, specifically a bridge deck slope measuring device for municipal roads and bridges. Background Technology

[0002] Detecting bridge slope is a crucial step in ensuring the structural safety, traffic function, and service life of bridges. Its core purpose is to identify potential problems, verify design compliance, and guide operation and maintenance decisions by accurately measuring slope parameters. Since bridge slope is not constant and is affected by factors such as vehicle load, temperature changes, geological settlement, and material aging over a long period of time, non-design slope deviations may occur. Therefore, slope detection can promptly identify these hidden structural defects and prevent risks from escalating.

[0003] Traditional fixed slope meters and separate leveling instrument kits typically lack integrated moving parts, requiring multiple people to carry them or external tools for transport. In large-scale testing scenarios such as long-span bridges and viaducts, this is inefficient and prone to damaging internal precision components due to collisions. Furthermore, some traditional devices require adjusting the testing angle by tightening bolts or manually prying the testing components to change their tilt, which is laborious and lacks the ability to quickly fine-tune adjustments, making it difficult to adapt to different bridge slope requirements. These shortcomings make them unsuitable for practical use. Therefore, we propose a bridge deck slope measuring device for municipal roads and bridges. Utility Model Content

[0004] The purpose of this invention is to provide a bridge deck slope measuring device for municipal roads and bridges to solve the problems mentioned in the background art.

[0005] To address the aforementioned technical problems, this application provides a bridge deck slope measuring device for municipal roads and bridges, comprising a vehicle body, a support plate fixedly installed on the upper end of the vehicle body, a rotating groove formed in the middle of the support plate, mounting plates fixedly installed on both sides of the middle of the rotating groove, angle pointers on the surfaces of both mounting plates, a rotating ring rotatably installed in the middle of the rotating groove, a gear ring fixedly installed on the outer side of the rotating ring, an adjusting rotating groove formed on one side of the middle of the support plate, a gear rotatably installed in the middle of the adjusting rotating groove, a crank handle fixedly installed at both ends of the gear, a fixing tube fixedly installed in the middle of the rotating ring, a columnar level clamped in the middle of the fixing tube, and pointers fixedly installed above and below the middle of both sides of the rotating ring.

[0006] In some embodiments, fixing plates are fixedly installed at the four corners of the lower end of the support plate, and the support plate is fixedly connected to the vehicle body through the fixing plates.

[0007] In some embodiments, omnidirectional wheels are fixedly installed at the four corners of the lower end of the vehicle body.

[0008] In some embodiments, a push handle is fixedly installed at one end of the vehicle body.

[0009] In some embodiments, the rotating groove and the adjusting rotating groove are connected, the gear and the gear ring mesh, and the rotating ring is located in the middle of the two mounting plates.

[0010] In some embodiments, a slot is provided in the middle of the fixed tube, the columnar level is engaged in the middle of the slot, and the center line of the pointer and the air bubble filled with liquid in the columnar level are on the same center line.

[0011] This utility model has at least the following beneficial effects:

[0012] 1. This utility model offers high flexibility in adjustment and movement during use, effectively adapting to multi-area bridge deck inspection. Through the meshing transmission structure formed by the adjusting groove of the support plate, gears, and the toothed ring of the rotating ring, simply turning the crank handle drives the rotating ring to rotate within the groove, thereby adjusting the tilt angle of the fixed tube and columnar level. This allows for rapid adaptation to different inspection requirements regarding the transverse and longitudinal slopes of the bridge deck. Furthermore, the limiting design of the groove on the rotating ring ensures safe and non-deviation-prone adjustment. Combined with the omnidirectional wheels and push handle of the vehicle body, operators can easily move the device to any area of ​​the bridge deck, making it suitable for full-area inspection of large-span bridges.

[0013] 2. When using this utility model, the slot in the middle of the fixing tube adopts a snap-fit ​​design, and the columnar level can be directly plugged in and replaced. When the level has problems such as glass breakage or liquid leakage, there is no need to disassemble the rotating ring, support plate and other overall structures. Only the level needs to be replaced separately, which greatly shortens the maintenance time and reduces equipment downtime costs, and has high practicality. Attached Figure Description

[0019] 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.

[0020] Example 1: Please refer to Figure 1 - Figure 4 This utility model provides a technical solution: a bridge deck slope measuring device for municipal roads and bridges, including a vehicle body 1, with a support plate 2 fixedly installed on the upper end of the vehicle body 1. The device is characterized by: a rotating groove 21 in the middle of the support plate 2; mounting plates 31 fixedly installed on both sides of the middle of the rotating groove 21; angle pointers 32 on the surface of both mounting plates 31; a rotating ring 22 rotatably installed in the middle of the rotating groove 21; a toothed ring 23 fixedly installed on the outer side of the rotating ring 22; an adjusting rotating groove 24 on one side of the middle of the support plate 2; and a gear 25 rotatably installed in the middle of the adjusting rotating groove 24. A crank handle 26 is fixedly installed at both ends of the wheel 25. A fixed tube 28 is fixedly installed in the middle of the rotating ring 22. A columnar level 30 is snapped into the middle of the fixed tube 28. A pointer 27 is fixedly installed above and below the middle of both sides of the rotating ring 22. The rotating groove 21 and the adjusting rotating groove 24 are connected. The gear 25 and the gear ring 23 mesh. The rotating ring 22 is located in the middle of the two mounting plates 31. A slot 29 is opened in the middle of the fixed tube 28. The columnar level 30 is snapped into the middle of the slot 29. The center line of the pointer 27 and the air bubble filled with liquid in the columnar level 30 are on the same center line.

[0021] In this embodiment, the operator can rotate the handle 26 to drive the gear 25 to rotate, which in turn drives the rotating ring 22 to rotate within the rotating groove 21 through meshing with the gear ring 23. This allows for quick adjustment of the tilt angle of the fixed tube 28 and the internal columnar level 30, adapting to different testing requirements such as the transverse slope and longitudinal slope of the bridge deck. The rotation range of the rotating ring 22 is limited by the rotating groove 21, preventing it from shifting. The angle pointers 32 on the surfaces of the two mounting plates 31 provide a scale reference for the rotation angle of the rotating ring 22. Because the pointers 27 on both sides of the rotating ring 22 are... The bubble centerline of the columnar level 30 is preset to the same reference. When measuring the rotating ring 22, it is only necessary to observe whether the bubble of the columnar level 30 is in the middle of the columnar level 30. If the bubble of the columnar level 30 is in the middle, the slope angle can be read directly by the index pointed to by the pointer 27. If the columnar level 30 is damaged, such as glass breakage or liquid leakage, it is not necessary to disassemble the entire rotating ring 22 or the fixing tube 28. The old level can be directly taken out from the slot 29 and the new level can be inserted, thereby greatly shortening the maintenance time.

[0022] Example 2: As Figure 1 - Figure 3 As shown, a fixing plate 13 is fixedly installed at each of the four corners of the lower end of the support plate 2. The support plate 2 is fixedly connected to the vehicle body 1 through the fixing plate 13. A universal wheel 12 is fixedly installed at each of the four corners of the lower end of the vehicle body 1. A push handle 11 is fixedly installed at one end of the vehicle body 1.

[0023] In this embodiment, the vehicle body 1 is used to support the entire device. With the help of the casters 12 and push handle 11 below, the entire device can be moved quickly. The push handle 11 is fixed to one end of the vehicle body 1, which conforms to the ergonomic design. The operator can stand behind the device and easily control the direction and speed of the device's movement through the push handle without having to bend over or exert force, thus avoiding fatigue in the waist and arms caused by long-term testing.

[0024] Working principle:

[0025] like Figure 1 - Figure 4 As shown, during use, the entire device is moved to the bridge to be tested using the push handle 11 and the casters 12. At this time, the columnar level 30 and the pointer 27 are in their initial positions, i.e., parallel, and the pointer 27 is at the zero mark of the angle pointer 32. Then, the operator moves the entire device forward along the bridge using the push handle 11. During this process, as the slope of the bridge changes, the air bubbles in the liquid of the columnar level 30 will shift and will not be at the center line. The user can rotate the gear 25 by turning the crank handles 26 on both sides, which in turn drives the meshing gear ring 23 to drive the rotating ring 22 fixedly connected to it to rotate. When the rotating ring 22 rotates, it will drive the columnar level 30 in the middle of the internal fixed tube 28 to rotate synchronously until the air bubbles in the liquid inside the columnar level 30 are at the highest point in the middle of the columnar level 30. At this time, the user can observe that the pointer 27 will move to a certain mark of the angle pointer 32, and record the mark to obtain the slope of the bridge surface. The inspector can move to a certain point and stop, waiting for the liquid in the columnar level 30 to stabilize before recording the accurate value. If the columnar level 30 is damaged, such as by broken glass or liquid leakage, there is no need to disassemble the entire rotating ring 22 or the fixing tube 28. The old level can be directly removed from the slot 29 and the new level can be inserted, thus greatly shortening the maintenance time.
