Description

Technical Field

[0001] This utility model relates to the field of bridge engineering technology, specifically to an angle measuring instrument for bridge engineering inspection. Background Technology

[0002] A beam generally refers to a structure erected over rivers, lakes, and seas to allow vehicles and pedestrians to pass smoothly. To adapt to the modern, rapidly developing transportation industry, the term "bridge" has also been extended to refer to a structure erected to cross mountains, adverse geological conditions, or meet other transportation needs, making passage more convenient. When constructing bridge projects, angle measuring instruments are needed to inspect the bridge structure.

[0003] Chinese patent discloses an angle measuring instrument for bridge engineering inspection, publication number CN115290049A. It includes a rotating base, with a support plate fixedly connected to the top of the rotating base. An adjusting wheel is mounted on the top of the support plate, and a theodolite is mounted on the side of the adjusting wheel. A dust cap is movably connected to one end of the theodolite. By inserting a locking block from a limiting plate into the side of the instrument, the protective cap can be further reinforced, resulting in a better fixation of the protective cap. This ensures that the instrument's lens is not corroded by dust from the outside air, thus extending the instrument's service life.

[0004] However, the following drawbacks still exist: the angle measuring instrument used for bridge engineering inspection cannot accurately adjust the level of the measuring instrument during inspection. Therefore, an angle measuring instrument for bridge engineering inspection was designed. Utility Model Content

[0027] Example 1

[0028] Please see Figures 1-5 As shown, an angle measuring instrument for bridge engineering inspection includes a base 1, a leveling mechanism 2 fixedly mounted on the top surface of the base 1, and a measuring mechanism 3 fixedly mounted on the top surface of the leveling mechanism 2. The leveling mechanism 2 includes a leveling part and a power part, with the front and back of the power part fixedly connected. The power part includes a fixing plate 201, with the bottom surfaces of the left and right ends of the base 1 respectively fixedly connected to the top surfaces of the two fixing plates 201, and motors 202 fixedly mounted on the back of each of the two fixing plates 201. The measuring mechanism 3 includes a measuring part and a connecting part, with the top surface of the connecting part fixedly connected to the bottom surface of the measuring part. The connecting part includes a hinge block 301, with two support frames 302 respectively disposed inside the two hinge blocks 301.

[0029] During operation, the level of the measuring instrument 303 is observed to determine if it is level. If it is not level, leveling is required. The motor 202 corresponding to the side that is not level is activated to make the turntable 203 rotate.

[0030] Furthermore, the front of the output rods of the two motors 202 extends through the back of the two fixing plates 201 to the front of the two fixing plates 201 respectively. The model of the motors 202 is Y2-112M-6. Two turntables 203 are fixedly installed on the front of the output rods of the two motors 202 respectively. A connecting plate 204 is hinged to the front surface of the turntables 203.

[0031] When in operation, the corresponding motor 202 is started, causing the turntable 203 to rotate, thereby pulling the connecting plate 204 to move.

[0032] Furthermore, two sliding plates 205 are respectively hinged to the inner walls of the top of the two connecting plates 204, and two placement plates 207 are respectively sealed on the left and right sides of the top of the base 1. The left and right sides of the top of the base 1 are respectively hinged to the inner sides of the two placement plates 207 by hinge rods.

[0033] During operation, the turntable 203 rotates, thereby pulling the connecting plate 204 to move, and the sliding plate 205, which is hinged to the connecting plate 204, moves up and down.

[0034] Furthermore, the sides of the two slide plates 205 respectively rub against and slide in contact with the interior of the left and right ends of the base 1, and two connecting blocks 206 are respectively hinged to the inner walls of the top of the two slide plates 205, and the top surfaces of the two connecting blocks 206 are respectively fixedly connected to the bottom surfaces of the two placement plates 207.

[0035] During operation, the slide plate 205, which is hinged to the connecting plate 204, moves up and down, while simultaneously causing the placement plate 207 to deflect at an angle along the hinge rod. Observe the horizontal position, and adjust it to allow the measuring instrument body 303 to work.

[0036] Furthermore, two movable bases 208 are fixedly installed on the bottom surfaces of the front and rear ends of the base 1, and multiple movable wheels are installed inside the movable base 208. The top surfaces of the two placement plates 207 are fixedly connected to the bottom surfaces of the two hinge blocks 301, and the interiors of the two hinge blocks 301 are hinged to the inner walls of the two support frames 302.

[0037] During operation, the base 1 is moved to the position where the bridge angle needs to be detected by moving the base 208.

[0038] Furthermore, a measuring instrument body 303 is fixedly mounted on the top surface of the two support frames 302, a level is mounted on the front of the measuring instrument body 303, a rotating rod 305 is mounted inside the fixed seat below the measuring instrument body 303, the surface of the rotating rod 305 and the inner wall of the fixed seat below the measuring instrument body 303 are rotatably connected by a bearing, and a handle 304 is fixedly mounted on the bottom surface of the rotating rod 305.

[0039] During operation, rotating the handle 304 causes the rotating rod 305 to drive the measuring instrument body 303 to rotate 360 ​​degrees, thereby completing the measurement work.

[0040] Working principle: In use, the base 1 is moved to the position where the bridge angle needs to be detected by moving the base 208. The level of the measuring instrument body 303 is observed by observing whether it is level. If it is not level, it needs to be leveled. The motor 202 of the side that is not level is started, so that the turntable 203 rotates, thereby pulling the connecting plate 204 to move. The sliding plate 205 hinged to the connecting plate 204 moves up and down, while the placement plate 207 is driven to bend along the hinge rod at an angle. Observe the horizontal position. Once leveled, the measuring instrument body 303 can start working. Turn the handle 304 so that the rotating rod 305 drives the measuring instrument body 303 to rotate 360 ​​degrees, thereby completing the measurement work.
