Description

Technical Field

[0001] This utility model relates to the field of measuring equipment technology, specifically to a road and bridge construction measuring device. Background Technology

[0002] Current road and bridge construction surveying equipment has several shortcomings. The height adjustment of its support structure is complex, making it difficult to accurately position to the ideal height. Furthermore, the locking mechanism is unreliable and prone to loosening and displacement. Additionally, the measuring instrument is not securely mounted on the equipment; in the complex environment of a construction site, even slight vibrations or impacts can cause inaccurate measurement data. These problems result in low measurement efficiency and insufficient accuracy, failing to effectively meet the high-precision construction surveying requirements for roads and bridges, seriously affecting project quality and progress, and urgently requiring improvement and refinement.

[0003] Chinese patent document CN219223723U discloses a road and bridge construction surveying device. It includes a support plate, the upper surface of which is fixedly connected to the bottom end of a connecting sleeve. A rotating column is connected to the top end of the connecting sleeve, and a placement plate is fixedly connected to the top end of the rotating column. This application utilizes a design incorporating a glass cup, a horizontal floating plate, a horizontal line, a spiral connecting cylinder, and an adjusting spiral rod. The adjusting spiral rod is rotated according to the ground flatness. Finally, the support plate causes the liquid in the glass cup to sway along a rope, so that when the glass cup stops swaying, the edge of the horizontal floating plate coincides with the horizontal line. Finally, the level laser on the placement plate is in a horizontal position, making the process convenient and quick.

[0004] Although the device described in the aforementioned literature can improve the water balance of the equipment, its structure is relatively simple, making it inconvenient to adjust the length of the support structure and slightly lacking in flexibility in use. In addition, the placement of the measuring instrument is not stable enough, resulting in low practicality. Utility Model Content

[0005] The main purpose of this invention is to provide a road and bridge construction surveying device that can effectively solve the above-mentioned problems.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A road and bridge construction surveying device includes a support frame, with support devices fixedly connected to all four walls of the support frame, a hook fixedly connected to the middle of the lower end of the support frame, an installation structure fixedly connected to the upper end of the support frame, and a measuring instrument movably connected to the upper end of the installation structure. The support device includes a first connecting seat, which is fixedly mounted on the four walls of the bracket; The mounting structure includes a connecting plate, the lower end of which is fixedly connected to the upper end of the bracket.

[0007] Preferably, the upper end of the bracket is provided with a reserved hole, and a control button is fixedly connected to one side of the bracket.

[0008] Preferably, a first rotating handle is movably connected to one side of the first connecting seat, a damping shaft is provided between the first rotating handle and the lower end of the first connecting seat is movably connected to a rotating plate.

[0010] Preferably, the lower end of the telescopic rod is fixedly connected to a second connecting seat, one side of the second connecting seat is movably connected to a second rotating handle, and the lower end of the second connecting seat is movably connected to a support leg.

[0011] Preferably, a gear is movably connected to the upper middle part of the connecting plate, a third rotating handle is connected to one side of the gear, and a first rotating rod is fixedly connected to the lower end of the third rotating handle.

[0012] Preferably, a second rotating rod is fixedly connected to the upper end of the gear, a placement platform is fixedly connected to the upper end of the second rotating rod, and a fixing plate is fixedly connected to the upper end of the placement platform.

[0013] Preferably, an electric telescopic rod is fixedly connected to one side of the fixed plate, a clamping plate is fixedly connected to one end of the electric telescopic rod, and a protective pad is fixedly connected to one side of the clamping plate.

[0014] Compared with the prior art, the present invention has the following beneficial effects: This utility model provides a road and bridge construction surveying device. The device is equipped with a support system, and the adjustable support legs can adapt to different terrains, ensuring the device remains level and stable in complex environments. The quick-locking spring clips reduce the risk of loosening after adjustment, further enhancing stability. The spring clip design allows for quick fixation after the support leg length is adjusted, eliminating cumbersome operations, significantly shortening setup time and improving construction efficiency. By flexibly adjusting the support leg length, the device can adapt to uneven construction ground. The stability of the spring clips ensures that measurement accuracy is unaffected by terrain changes. The quick-locking function reduces the difficulty of manual operation, allowing even non-professionals to quickly set up the device, reducing human error. The adjustable support leg design makes the device more compact when stored, and the lightweight structure of the spring clips facilitates transportation and carrying. Rotating the first handle clockwise or counterclockwise causes the support components to open and close at different angles. The telescopic rod allows for adjustment of the support component length, flexibly changing the device height. The spring clips provide quick locking and fixation, making the structural connection more stable. Similarly, rotating the second handle in different directions facilitates adjustment of the tilt angle of the support legs.

[0015] This utility model provides a road and bridge construction surveying device. The device is equipped with an installation structure, and the gear transmission provides smooth and continuous steering control, which can finely adjust the orientation of the measuring instrument, avoid the error of manual adjustment, and improve the accuracy of the measurement angle. The adjustable clamping structure can adapt to measuring instruments of different sizes, achieve fixation in seconds, and reduce setup time. The combination of gear steering and clamping structure allows a single person to quickly switch the measurement direction or change instruments without moving the main body of the device, adapting to multi-task scenarios. The clamping structure fixes the instrument by applying force evenly, avoiding the offset or shaking caused by traditional binding methods. Combined with the damping feel of gear steering, it further ensures measurement accuracy. The integrated steering and clamping modules reduce the need for additional accessories, making the device structure more compact, easy to transport and deploy on site. Turning the third handle causes the gear to rotate, which in turn causes the second rotating rod to drive the placement platform to rotate until it is adjusted to a suitable angle. After the measuring instrument is placed on the placement platform, the position of the clamping plate is adjusted by the extension and retraction of the electric telescopic rod until the measuring instrument is clamped and fixed.

Supporting devices 2 are fixedly connected to all four walls of the support frame 1. Adjustable support legs adapt to different terrains, ensuring the device remains horizontally stable in complex environments. The quick-locking spring clips reduce the risk of loosening after adjustment, further enhancing stability. The spring clip design allows for quick fixing after support leg length adjustment, eliminating cumbersome operations and significantly shortening setup time, thus improving construction efficiency. By flexibly adjusting the support leg length, the device can adapt to uneven construction ground. The stability of the spring clips ensures that measurement accuracy is unaffected by terrain changes. The quick-locking function reduces the difficulty of manual operation, allowing even non-professionals to quickly set up the device, reducing human error. The adjustable support legs make the device more compact when stored, and the lightweight structure of the spring clips facilitates transportation and carrying. The lower middle of the bracket 1 is fixedly connected to a hook 3, and the upper end of the bracket 1 is fixedly connected to an installation structure 4. The gear transmission provides smooth and continuous steering control, which can finely adjust the orientation of the measuring instrument, avoid the error of manual adjustment, and improve the accuracy of the measurement angle. The adjustable clamping structure can adapt to measuring instruments of different sizes, achieve second-level fixation, and reduce setup time. The combination of gear steering and clamping structure allows a single person to quickly switch the measurement direction or change the instrument without moving the main body of the device, adapting to multi-task scenarios. The clamping structure fixes the instrument by applying force evenly, avoiding the offset or shaking caused by traditional binding methods. Combined with the damping feel of gear steering, it further ensures measurement accuracy. The integrated steering and clamping module reduces the need for additional accessories, making the equipment structure more compact and convenient for transportation and on-site deployment. The upper end of the installation structure 4 is movably connected to the measuring instrument 5. The support device 2 includes a first connecting seat 21, which is fixedly mounted on the four walls of the bracket 1; The mounting structure 4 includes a connecting plate 41, the lower end of which is fixedly connected to the upper end of the bracket 1. The upper end of bracket 1 is provided with a reserved hole, and a control button is fixedly connected to one side of bracket 1.

[0020] like Figure 2As shown, a first rotating handle 22 is movably connected to one side of the first connecting seat 21. A damping shaft is provided between the first connecting seat 21 and the first rotating handle 22. A rotating plate 23 is movably connected to the lower end of the first connecting seat 21. A sliding plate 24 is fixedly connected to the lower end of the rotating plate 23. Slots are provided at the bottom of both sides of the sliding plate 24. A telescopic rod 25 is slidably connected to the inner wall of the sliding plate 24. Spring buckles 26 are fixedly connected to the upper parts of both sides of the telescopic rod 25. A second connecting seat 27 is fixedly connected to the lower end of the telescopic rod 25. A second rotating handle 28 is movably connected to one side of the second connecting seat 27. A support leg 29 is movably connected to the lower end of the second connecting seat 27. Rotating the first rotating handle 22 clockwise or counterclockwise causes the support component to open and close at different angles. The telescopic rod 25 allows the length of the support component to be adjusted, flexibly changing the height of the equipment. The spring buckles 26 can be quickly locked and fixed, making the structural connection more stable. Similarly, rotating the second rotating handle 28 in different directions facilitates the adjustment of the tilt angle of the support leg 29. like Figure 3 and Figure 4 As shown, a gear 42 is movably connected to the upper middle part of the connecting plate 41. A third rotating handle 43 is connected to one side of the gear 42. A first rotating rod 44 is fixedly connected to the lower end of the third rotating handle 43.

After the measuring instrument 5 is placed on the placement platform 46, the position of the clamping plate 49 is adjusted by the telescopic movement of the electric telescopic rod 48 until the measuring instrument is clamped and fixed.

[0021] The working principle of this utility model is as follows: By rotating the first handle 22 clockwise or counterclockwise through the support device 2, the support component can be opened and closed at different angles. The telescopic rod 25 allows the length of the support component to be adjusted, flexibly changing the height of the equipment. The spring buckle 26 can be quickly locked and fixed, making the structural connection more stable. Similarly, rotating the second handle 28 in different directions facilitates the adjustment of the tilt angle of the support leg 29. Using the mounting structure 4, the third handle 43 is turned, causing the gear 42 to rotate, thereby causing the second rotating rod 45 to drive the placement platform 46 to rotate until it is adjusted to a suitable angle. After the measuring instrument 5 is placed on the placement platform 46, the position of the clamping plate 49 is adjusted by the telescopic adjustment of the electric telescopic rod 48 until the measuring instrument is clamped and fixed.
