Description

Technical Field

[0001] This utility model belongs to the field of testing equipment technology, and in particular relates to a non-contact rotary leveling intelligent bridge deflection testing instrument. Background Technology

[0002] The non-contact rotary leveling intelligent bridge deflection detector is an instrument used to measure deflection. 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, and deformation and vibration displacement of beams and columns of large-span structures, high-rise buildings, lifting machinery, drilling platforms, etc.

[0003] Currently, deflectometers used to measure bridge deflection can perform multi-point measurements and provide relatively accurate data. However, since most bridges are located in remote areas with limited natural environments, deflectometers require on-site scaffolding, making them inconvenient to use. Due to terrain conditions, deflectometers are prone to swaying or tipping, causing them to deviate and affecting the stability and consistency of their height during actual use. This, in turn, affects the accuracy of bridge deflection measurements.

[0004] To address this, a non-contact rotary leveling intelligent bridge deflection detector is proposed. Utility Model Content

[0026] 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.

[0027] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0028] Reference Figures 1 to 5 As shown, this embodiment provides a non-contact rotary leveling intelligent bridge deflection detector, including:

[0029] Total station;

[0030] The connecting mechanism includes an upper turntable 5 and a lower turntable 6, which are rotatably connected. The upper turntable 5 is fixedly connected to the bottom of the instrument base 1 on the total station.

[0031] The support frame includes several telescopic legs 7, which are evenly fixed to the bottom of the lower turntable 6. The bottom of the telescopic legs 7 is hinged to an anti-slip plate 8 via a ball joint. Several anti-slip nails 9 are fixed to the bottom surface of the anti-slip plate 8. Ground nails 10 are slidably connected through the anti-slip plate 8.

[0032] The total station is used to detect bridge deflection. The connecting mechanism allows the total station to be connected to the support frame while also allowing the total station to rotate circumferentially, facilitating adjustment of the measurement orientation. The support frame supports the total station on the ground, and the telescopic legs 7 can change the height of the total station. Under harsh outdoor conditions, if the bottom surface is relatively flat and smooth, the anti-slip plate 8 can increase the contact area between the bottom of the telescopic legs 7 and the ground, and the anti-slip studs 9 further increase the friction, making the detector stable and preventing it from sliding. For uneven ground, when the contact area between the anti-slip plate 8 and the ground is small, the anti-slip studs 9 can be inserted into the ground to make the detector stable. This application, through the anti-slip plate 8, anti-slip studs 9, and ground spikes 10, can cope with the harsh outdoor environment of outdoor deflection detection, allowing the detector to be placed stably and preventing it from sliding, whether on smooth and flat ground or uneven ground.

[0033] The design is further optimized. A fixing sleeve 11 is fixedly connected to the top surface of the anti-slip plate 8. A ground nail 10 passes through the fixing sleeve 11 and the anti-slip plate 8. A pin hole 12 is opened at the bottom of the ground nail 10 and on the side of the fixing sleeve 11, and a fixing pin 13 is inserted into the pin hole 12.

[0034] When the testing instrument is used on a smooth and flat surface, only the anti-slip plate 8 and anti-slip nail 9 need to be in contact with the ground. Without the need for the ground nail 10, the fixing pin 13 is inserted into the pin hole 12 to fix the ground nail 10 inside the anti-slip plate 8, preventing the tip of the ground nail 10 from injuring people and also protecting the tip of the ground nail 10 from wear.

[0035] The scheme is further optimized. The measuring lens 4 on the total station is connected to a protective cover 14 by an external thread. The display screen 2 on the total station is covered with a dust cover 15. The top of the dust cover 15 is rotatably connected to the instrument base 1 on the total station above the display screen 2.

[0036] The protective cover 14 is placed over the lens when the lens is not in use to protect the lens. The dust cover 15 protects the display screen 2 from dust or scratches, and also blocks outdoor sunlight to prevent the display screen 2 from reflecting light and causing unclear readings by the testers.

[0037] The scheme is further optimized. A rotating collar 16 is fixed to the outside of the bracket 3 on the total station. A rotating column 17 is rotatably connected inside the rotating collar 16. The top side of the rotating column 17 extends outward and is fixed to a mounting frame 18. A rangefinder 19 is fixed inside the mounting frame 18.

[0038] The distance measuring instrument 19 can measure the height between the total station and the ground. By monitoring, it ensures that the height of the total station remains constant during the measurement process, avoiding measurement errors and making the measurement results more accurate. The distance measuring instrument 19 is rotated outward when in use and rotated back to the position close to the bracket 3 when not in use, which can reduce the impact of the distance measuring instrument 19 during movement.

[0039] The design is further optimized by providing several slots 20 evenly spaced around the top of the rotating collar 16, and the rotating column 17 is engaged with corresponding slots 20 by locking teeth 21.

[0040] The locking tooth 21 is locked in the locking groove 20, and its position can be changed by lifting and rotating. The locking between the locking groove 20 and the locking tooth 21 can fix the position of the rangefinder 19 before and after rotation, so as to avoid the rangefinder 19 from rotating freely and causing inaccurate measurement results.

[0041] The design has been further optimized. A plug-in post 22 is fixedly connected to the upper turntable 5, and a folding umbrella 23 is inserted into the plug-in post 22.

[0042] A folding umbrella 23 is inserted into the plug post 22 to prevent the detector from being exposed to direct sunlight and irreversible damage caused by heavy rain. It also provides a place for the testing personnel to be shaded and sheltered from the rain, which is beneficial to the comfort and convenience of the operators.

[0043] In a further optimized design, a first gear 24 is rotatably connected to the bottom center of the upper turntable 5, and a gear cavity 25 is opened at the top of the lower turntable 6. The first gear 24 is meshed with a second gear 26. Both the first gear 24 and the second gear 26 are located in the gear cavity 25. The bottom end of the gear shaft of the first gear 24 passes through the lower turntable 6 and is threadedly connected to a fastening nut 27.

[0044] By inserting the first gear 24 at the bottom of the upper turntable 5 into the gear cavity 25 to mesh with the second gear 26, and having its gear shaft pass through the lower turntable 6 and connect to the fastening nut 27, the upper turntable 5 and the lower turntable 6 can be installed quickly, thereby quickly installing the total station and the support frame; the meshing connection of the first gear 24 and the second gear 26 allows the upper turntable 5 to rotate stably.

[0045] In a further optimized design, a friction ring 28 is abutted below the second gear 26. The friction ring 28 is located in the gear cavity 25. Several sliding pillars 29 are circumferentially fixed to the bottom surface of the friction ring 28. A spring 30 is provided on the outer sleeve of the sliding pillars 29. The bottom end of the sliding pillars 29 passes through the lower turntable 6 and is fixed to a connecting plate 31. A handle 32 is fixed to the lower end of the connecting plate 31.

[0046] In the initial state, the spring 30 pushes up the friction ring 28, causing the friction ring 28 to abut against the second gear 26, which restricts the rotation of the second gear 26, and in turn restricts the rotation of the first gear 24, the upper turntable 5, and the total station, preventing the total station from rotating freely in the initial state. During adjustment, the friction ring 28 is pulled down by the handle 32, the spring 30 is compressed, and a gap is created between the friction ring 28 and the second gear 26, at which point the total station wheel can rotate freely.

[0047] Any aspects of this utility model that are not detailed herein are conventional technical means known to those skilled in the art.
