The construction of bridges requires detailed planning, design, and the construction process involves considerations in aspects such as engineering technology, geological conditions, and environmental protection.

[0003] In the prior art, in the height measurement and survey of bridges, generally a suitable location is found at the bottom of the bridge and measurements are taken upwards. Not only is it difficult to find a horizontal position, but it is also not easy for the operators to go down. Based on this demand, we have proposed a height surveying device for bridge engineering. Content of the Utility Model

[0004] The purpose of the utility model is to provide a height surveying device for bridge engineering to solve the problems existing in the prior art proposed in the above background technique.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0006] A height surveying device for bridge engineering includes an L-shaped plate, which is jointly composed of a horizontal plate and a vertical plate. A fixing device is penetrated through the horizontal plate. A placing seat is fixedly connected to the side wall of the vertical plate. A placing groove is penetrated through the placing seat.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0017] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0018] Refer to Figure 1-2, A height survey device for bridge engineering, including an L-shaped plate 1. The L-shaped plate 1 is composed of a horizontal plate and a vertical plate. A spirit level 3 is fixedly connected to the side wall of the horizontal plate. The spirit level 3 is used to determine whether the L-shaped plate 1 is placed horizontally. A fixing device is arranged through the horizontal plate. The fixing device includes a threaded groove arranged through the horizontal plate. An adjusting stud 2 is threadedly connected through the threaded groove. The lower end of the adjusting stud 2 is rotatably connected to a pressing plate 8.

[0019] Wherein, a placing seat 5 is fixedly connected to the side wall of the vertical plate. A placing groove is arranged through the placing seat 5. A laser measuring instrument main body 4 is arranged in the placing groove. An adjusting device is threadedly connected through the inner wall of the placing groove. The adjusting device includes an adjusting screw 7 threadedly connected through the inner wall of the placing groove. The tail end of the adjusting screw 7 is rotatably connected to a fixing plate 6. The side wall of the fixing plate 6 abuts against the side wall of the laser measuring instrument main body 4.

[0020] Specifically, a bottom plate 10 is arranged below the vertical plate. The lower end of the vertical plate is connected to the bottom plate 10 through two first electric push rods 9. A limiting device is fixedly connected to the lower end of the bottom plate 10. The limiting device includes a second electric push rod 11 fixedly connected to the lower end of the bottom plate 10. A clamping plate 12 is fixedly connected to the extending end of the second electric push rod 11. A moving screw 13 is threadedly connected through the side wall of the clamping plate 12. The tail end of the moving screw 13 is rotatably connected to a limiting plate 14. The limiting plate 14 is located behind the bottom plate 10.

[0021] Specifically, when the limiting plate 14 completely abuts against the side wall of the clamping plate 12, the rear side of the limiting plate 14 just remains flush with the rear side of the bottom plate 10. When the limiting plate 14 is not in use and remains flush with the bottom plate 10, it can avoid the limiting plate 14 affecting the perpendicularity between the L-shaped plate 1 and the bridge side wall. The vertical plate, the bottom plate 10 and the limiting plate 14 can be on the same vertical line.

[0022] In the present utility model, the operator makes the L-shaped plate 1 stuck on the railing of the bridge, and touches the ground with the pressing plate 8 by adjusting the corresponding adjusting stud 2 for fixing and leveling the L-shaped plate 1. The operator steps on the ground to stabilize the position of the L-shaped plate 1. At the same time, rotate the adjusting screw 7 on one side to drive the fixing plate 6 to move forward. After fixing the measuring instrument main body 4 in the placing groove, the bridge measurement can be started.

[0023] When it is necessary to subtract the thickness of the bridge itself, the second electric push rod 11 can be used to drive the clamping plate 12 to move directly below the laser measuring instrument body 4. The clamping plate 12 provided on one side can play a role in positioning the bottom of the bridge. Remove the L-shaped plate 1 from the railing and adjust the corresponding moving screw 13 to make the limiting plate 14 protrude backward. Then re-place the L-shaped plate 1. Use the two first electric push rods 9 to move the bottom plate 10 downward so that the limiting plate 14 can move to the bottom of the bridge. Then let the two first electric push rods 9 return to their original positions. At this time, when the limiting plate 14 rises to a certain extent, it will be clamped to the bottom of the bridge. After observing that the bottom plate 10 cannot rise, the corresponding laser measuring instrument body 4 can be started. At this time, the measured distance is the distance reflected back by the clamping plate 12, which is the thickness of the bridge itself. Then subtraction can be used to obtain the actual height of the bridge.

[0024] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
