Description

Technical Field

[0001] This utility model relates to the field of road engineering surveying technology, and specifically to a road engineering surveying device. Background Technology

[0002] In road engineering surveying, the horizontal accuracy of the surveying equipment directly affects the accuracy of the data. Traditional equipment relies heavily on manual leveling, especially when working on sloping roads, where the support structure must be manually adjusted to ensure a level position. When the construction section has many continuous slopes or undulating terrain, operators need to frequently stop the machine for leveling, which not only increases the intensity of manual labor but also leads to frequent interruptions in surveying operations, severely reducing overall work efficiency and making it difficult to meet the needs of rapid surveying in modern road engineering.

[0003] Patent publication number CN214470955U discloses a road construction surveying system, which relates to the field of surveying equipment technology, specifically a road construction surveying system. The system includes a protective shell, a mobile base, and a monitoring instrument body. A wheel frame is rotatably connected to the lower part of the mobile base, and a roller is rotatably connected to one end of the wheel frame. A level is fixedly connected to the upper surface of the mobile base. A connecting block is fixedly connected to the lower part of the protective shell, and a fixing block is fixedly connected to the inner bottom wall of the protective shell. A cover plate is hinged to one side of the protective shell, and a rotating hydraulic rod is rotatably connected to one side of the cover plate.

[0004] When the above-mentioned device encounters a sloping road surface, it is manually leveled. However, when there are many sloping roads, the device needs to be leveled frequently, which leads to low work efficiency. Frequent adjustments can also cause wear and tear on the device parts, resulting in a decrease in surveying accuracy. Utility Model Content

[0033] 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.

[0034] like Figure 1-5 As shown, this utility model has the following three specific embodiments.

[0035] Example 1

[0036] This utility model provides a road engineering surveying device, including a protective shell 11, a sealing corrugated sleeve 12 fixedly connected to the top of the protective shell 11, a top plate 13 fixedly connected to the top of the sealing corrugated sleeve 12, a surveying instrument 14 movably connected to the top of the top plate 13, and a light shield 15 fixedly connected to the front of the surveying instrument 14.

[0037] It also includes an automatic leveling mechanism 2, a drive mechanism 3, a shock absorption mechanism 4, and a quick installation mechanism 5;

[0038] The automatic leveling mechanism 2 is located inside the protective shell 11 and is used to quickly level the surveying instrument 14;

[0039] The drive mechanism 3 is located at the bottom of the protective shell 11 for driving the device to move;

[0041] The quick-installation mechanism 5 is located at the connection between the surveyor 14 and the top plate 13, and is used for quick replacement of the surveyor 14.

[0042] In this embodiment, as Figure 1 As shown, the surveying instrument 14 is quickly installed via the quick-installation mechanism 5, and then the drive mechanism 3 is activated to move the device. When encountering a slope, traditional devices usually require manual leveling before continuing the survey. When encountering many slopes, the device needs to be leveled frequently, which is cumbersome. This device can automatically level itself via the automatic leveling mechanism 2, thereby greatly improving work efficiency. The vibration damping mechanism 4 can reduce the vibration of the device during operation, thereby improving the surveying quality of the surveying instrument 14. During the surveying process, the sunshade 15 can reduce the interference of sunlight on the surveying results. The sealing corrugated sleeve 12 can prevent the device from rotating circumferentially.

[0043] Example 2

[0044] The difference from Embodiment 1 is that this embodiment discloses a drive mechanism 3 and a quick-installation mechanism 5.

[0045] Preferably, the drive mechanism 3 includes a motor 31, which is fixedly connected to the bottom of the protective shell 11.

Adjacent pulleys 32 are connected by transmission through the belt 33. A driven wheel assembly 35 is rotatably connected to the rear bottom of the protective shell 11. A track 36 engages with the surfaces of the drive wheel assembly 34 and the driven wheel assembly 35. The drive wheel assembly 34 and the driven wheel assembly 35 are connected by transmission through the track 36.

[0046] The quick-installation mechanism 5 includes a connecting sleeve 51, which is fixedly connected to the top of the top plate 13. A slot 52 is provided inside the connecting sleeve 51. A connecting block 53 is inserted into the inside of the connecting sleeve 51. A locking block 54 is fixedly connected to the surface of the connecting block 53. The locking block 54 is inserted into the inside of the slot 52. A magnetic ring 55 is fixedly connected to the outside of the connecting block 53. The bottom of the magnetic ring 55 is magnetically connected to the top of the connecting sleeve 51.

[0047] In this embodiment, as Figure 3 and 5As shown, by aligning the card block 54 with the card slot 52 and engaging it inside the card slot 52, and then rotating the connecting block 53, the magnetic ring 55 is attracted to the top of the connecting sleeve 51, thereby quickly fixing the surveying instrument 14. Different surveying instruments 14 can be replaced according to road conditions for surveying work. By starting the motor 31, the motor 31 drives the drive wheel set 34 to rotate through the pulley 32 and belt 33. The drive wheel set 34 then drives the driven wheel set 35 to move through the track 36, thereby driving the device to move.

[0048] Example 3

[0049] The difference from Embodiment 2 is that this embodiment discloses an automatic leveling mechanism 2 and a shock absorption mechanism 4.

[0050] Preferably, the automatic leveling mechanism 2 includes a support frame 21, which is disposed on the top of the protective shell 11. A ball joint mounting ring 22 is fixedly connected to the middle of the support frame 21. A universal joint 23 is connected to the inside of the ball joint mounting ring 22. A counterweight 24 is fixedly connected to the bottom of the universal joint 23. The counterweight 24 is inverted conical. The top of the universal joint 23 is fixedly connected to the bottom of the top plate 13.

[0051] The shock absorption mechanism 4 includes a sleeve 41, which is fixedly connected to the bottom of the inner wall of the protective shell 11. A piston 42 is slidably connected inside the sleeve 41. A push rod 43 is fixedly connected to the top of the piston 42. A connecting plate 47 is connected to the top of the push rod 43 by a spherical hinge. The side of the connecting plate 47 is fixedly connected to the side of the support frame 21. A drain check valve 44 is provided on the top surface of the piston 42. The drain check valves 44 are arranged in a circumferential array. A return check valve 45 is fixedly connected to the side of the sleeve 41. The two ends of the return check valve 45 are respectively provided on the upper and lower sides of the piston 42. A spring 46 is provided on the outside of the sleeve 41.

[0052] The protective shell 11 and the counterweight 24 are made of high-density metal, the sealing corrugated sleeve 12 is made of flexible material, and the weight of the top plate 13 and the surveying instrument 14 is about three times that of the counterweight 24.

[0053] In this embodiment, as Figure 2 and 4 As shown, due to the gravity, the left and right counterweights 24 are always vertically downward. The counterweights 24 drive the universal ball joint 23 to rotate inside the ball joint mounting ring 22. Since the counterweights 24 are perpendicular to the top plate 13, the top plate 13 is kept in a horizontal state, thereby leveling the device. When encountering uneven road surfaces, the entire device will shake during movement. By draining the hydraulic oil inside the sleeve 41 through the drain check valve 44 and then returning it through the return check valve 45, the kinetic energy is absorbed, reducing the impact on the surveying instrument 14.

[0054] The working principle of this utility model is as follows.

[0055] By aligning the card block 54 with the card slot 52 and engaging it inside the card slot 52, and then rotating the connecting block 53, the magnetic ring 55 is attracted to the top of the connecting sleeve 51, thereby quickly fixing the surveying instrument 14. This allows for the replacement of different surveying instruments 14 according to road conditions for surveying work. By starting the motor 31, the motor 31 drives the drive wheel assembly 34 to rotate via the pulley 32 and belt 33. The drive wheel assembly 34 then drives the driven wheel assembly 35 to move via the track 36, thus moving the drive device. The counterweight 24 is always vertically downward, and the counterweight 24 drives the universal ball joint 23 to rotate inside the ball joint mounting ring 22. Since the counterweight 24 is perpendicular to the top plate 13, the top plate 13 is kept in a horizontal state, thus leveling the device. When encountering uneven road surfaces, the entire device will shake during movement. The hydraulic oil inside the sleeve 41 is discharged through the drain check valve 44 and then flows back through the return check valve 45, thereby absorbing kinetic energy and reducing the impact on the surveying instrument 14.

[0056] The preferred embodiments of this utility model disclosed above are merely illustrative of the present utility model. These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to any specific implementation. Clearly, many modifications and variations can be made based on the content of this specification. The selection and detailed description of these embodiments in this specification are intended to better explain the principles and practical applications of this utility model, thereby enabling those skilled in the art to better understand and utilize it.
