Description

Technical Field

[0001] This utility model relates to the field of surveying and mapping equipment technology, and in particular to an engineering surveying and mapping device. Background Technology

[0002] Engineering surveying is a fundamental task in fields such as engineering construction, topographic surveying, and urban planning. Its accuracy and efficiency directly affect the quality and progress of subsequent work. In engineering surveying operations, tripods, as one of the most common support devices, are widely used to support precision surveying instruments such as total stations, levels, GPS receivers, and laser scanners.

[0003] In existing technology, traditional surveying tripods typically consist of a top gimbal and three manually adjustable support legs. Height adjustment mainly relies on two methods: one is through sliding engagement between multiple leg sections, secured by knobs or lever-type locking mechanisms; the other is through coarse or fine adjustment via the lifting screw on the tripod's central axis.

[0004] However, the aforementioned existing technologies have revealed many shortcomings in practical use: poor terrain adaptability and low setup efficiency: When working on rugged, steep, or stepped terrain, operators need to repeatedly adjust the length of multiple sections on each support leg manually and repeatedly adjust the bubble level to make the instrument platform roughly level. Limited adjustment precision affects instrument centering and leveling: Manual adjustment has a large degree of subjectivity and uncertainty, making precise fine-tuning difficult. Cumbersome operation and heavy workload: The entire setup, leveling, and centering process is complicated, increasing operator fatigue and reducing overall work efficiency. The contradiction between stability and portability: In pursuit of stability, traditional tripods often use metal materials and increase structural strength, resulting in a large weight that is inconvenient for long-distance field transport.

[0005] Therefore, those skilled in the art urgently need a new type of support structure for engineering surveying devices, in order to achieve rapid, accurate, and automated leveling functions, and significantly improve the efficiency and adaptability of surveying operations. Utility Model Content

[0006] Therefore, it is necessary to provide an engineering surveying device that addresses the technical problem of insufficient leveling function of the support structure in existing engineering surveying devices.

[0007] An engineering surveying device includes a support mechanism and a supporting mechanism, with the supporting mechanism located at the top of the support mechanism.

[0008] The support mechanism includes a connecting rod and a tripod. The top of the connecting rod is movably connected to the bottom of the support mechanism; the top of the tripod is movably fitted onto the side surface of the connecting rod.

[0009] The tripod includes a main body and three support legs, the tops of which are connected to the side surfaces of the main body. The main body is movably fitted to the side surfaces of the connecting rod. Each support leg includes a first support portion, a second support portion, a coupling, a ball screw, and a micro motor. The top of the first support portion is connected to the side surface of the main body, and the bottom of the first support portion is connected to one end of the coupling. The top of the ball screw is connected to the other end of the coupling, and the bottom of the screw extends into the interior of the second support portion. The second support portion is a hollow, closed tube structure. The nut of the ball screw is located at the top opening of the second support portion and is connected to the screw, thus forming a telescopic structure between the first and second support portions. The micro motor is movably housed inside the second support portion, and the micro motor slides against the inner wall of the second support portion to limit the circumferential rotation between the micro motor and the second support portion. The output end of the micro motor is connected to the bottom end of the screw.

[0010] In one embodiment, the aforementioned support mechanism is equipped with several tilt sensors and a controller, thereby constituting a horizontal detection system for the support mechanism.

[0011] In one embodiment, each of the second support portions is provided with a guide rail and a slide block inside. The guide rail is disposed on the inner wall of the second support portion along the length direction of the second support portion. The slide block is slidably connected to the inner wall surface of the second support portion and slidably engaged with the guide rail.

[0012] In one embodiment, the corresponding micro motor described above is mounted on the slide.

[0013] In one embodiment, the aforementioned mating body includes three hinged portions and a first locking member. The three hinged portions are distributed at equal angles to the side surface of the mating body with the geometric central axis of the mating body as the axis. The first locking member is disposed through the side wall of the mating body and abuts against the side surface of the connecting rod.

[0014] In one embodiment, the aforementioned mating body is hinged to the top of the three first support portions via three hinged parts.

[0015] In one embodiment, the first locking member described above is threadedly engaged with the mating body.

[0016] In one embodiment, the aforementioned support mechanism includes a first connecting plate and a first rotary motor, with the bottom surface of the first connecting plate movably connected to the top end of the connecting rod; the output end of the first rotary motor is connected to the top surface of the first connecting plate.

[0017] In one embodiment, the support mechanism further includes a second connecting plate, a second rotary motor, and a mounting base. The second rotary motor is connected to the first rotary motor via a linkage group; the second connecting plate is connected to the output end of the second rotary motor; and the mounting base is connected to the second connecting plate.

[0018] In one embodiment, the bottom of the first connecting plate is provided with a connecting ball head, and correspondingly, the top of the connecting rod is movably provided with a connecting seat; the connecting ball head is movably fitted into the top of the connecting seat.

[0019] In one embodiment, the connecting seat is provided with a second locking member, which is threadedly engaged with the side wall of the connecting seat and abuts against the side surface of the connecting rod.

[0020] In one embodiment, the above-mentioned engineering surveying device further includes a surveying instrument body, which is mounted on a mounting base.

[0021] Compared to traditional tripods that require manual adjustment of the length of each leg section, the engineering surveying device described above features a micro-motor and ball screw mechanism within the three support legs that can independently and precisely extend and retract automatically. The operator only needs to roughly position the tripod, and the system can quickly restore the top support mechanism to a horizontal state by controlling the different strokes of the three motors. This greatly simplifies the setup process in complex terrain and saves a significant amount of adjustment time. It also provides a mechanical foundation for the subsequent integration of tilt sensors and control units. Based on the equipment's level detection or tilt detection system, the three micro-motors can be remotely controlled to extend and retract until the equipment is horizontal without manual intervention, while ensuring adjustment accuracy. The ball screw is used as the transmission core. The ball screw pair is a high-precision, high-efficiency mechanism that converts rotary motion into linear motion, providing the support legs with self-locking capability and extremely high rigidity.

[0029] Please see Figures 1 to 3This utility model discloses an engineering surveying device 1, which includes a support mechanism 10 and a support mechanism 20. The support mechanism 20 is disposed at the top of the support mechanism 10, thus forming a support module for the engineering surveying device 1 to support the main body of the adapted engineering surveying instrument, thereby providing a stable and easily adjustable surveying platform for the instrument, and thus collaboratively completing the surveying work. Specifically, the support mechanism 10 includes a connecting rod 11 and a tripod. The top of the connecting rod 11 is movably connected to the bottom of the support mechanism 20; the top of the tripod is movably fitted to the side surface of the connecting rod 11, so that the tripod can move along the length direction of the connecting rod 11, thereby adjusting the height difference between the tripod and the support mechanism 20, and realizing the first-level height adjustment of the support mechanism 20. Based on this, more specifically, the tripod includes a mating body 12 and three support legs 13, the tops of which are respectively connected to the side surfaces of the mating body 12; the mating body 12 is movably fitted to the side surface of the connecting rod 11; wherein, each support leg 13 includes a first support part 131, a second support part 132, a coupling 133, a ball screw, and a micro motor 134; the top of the first support part 131 is connected to the side surface of the mating body 12, and the bottom of the first support part 131 is connected to one end of the coupling 133; the top of the ball screw 135 is connected to the other end of the coupling 133, and the bottom of the screw 135 extends into the interior of the second support part 132; the second support part 132 is configured as a hollow closed tube structure, and the nut 136 of the ball screw is disposed on the second support part 132. The top opening of part 132 is connected to the screw 135 to form a telescopic structure between the first support part 131 and the second support part 132. The micro motor 134 is movably housed inside the second support part 132 and slides with the inner wall of the second support part 132 to limit the circumferential rotation between the micro motor 134 and the second support part 132. The output end of the micro motor 134 is driven to the bottom end of the screw 135, so that the micro motor 134 can drive the screw 135 to rotate relative to the nut 136, thereby enabling the first support part 131 and the second support part 132 to make adaptive telescopic adjustments according to the actual surveyed terrain. During this process, the coupling 133 enables free rotation between the first support part 131 and the screw 135.Traditional tripods require manual adjustment of the length of each leg section, making setup on uneven ground with varying elevations extremely time-consuming and labor-intensive. In contrast, the micro motors 134 and ball screw mechanisms within the three support legs 13 in this solution can independently and precisely extend and retract automatically. The operator only needs to roughly position the tripod, and the system can quickly restore the top support mechanism 20 to a horizontal state by controlling the different strokes of the three motors. This greatly simplifies the setup process in complex terrain and saves a significant amount of adjustment time. It also provides a mechanical foundation for the subsequent integration of tilt sensors and control units. Based on the equipment's level detection or tilt detection system, the three micro motors 134 can be remotely controlled to extend and retract until the tripod is horizontal without manual intervention, while ensuring adjustment accuracy. The use of ball screws as the transmission core, a high-precision and high-efficiency mechanism that converts rotary motion into linear motion, provides the support legs 13 with self-locking capability and extremely high rigidity.

[0030] Furthermore, in one embodiment, the support mechanism 20 is provided with a plurality of tilt sensors (not shown) and a controller (not shown) to form a level detection system for the support mechanism 20, and then automatically controls the micro motor 134 based on the level state of the support mechanism 20, thereby realizing the second-level height and level adjustment of the support mechanism 20.

[0031] Furthermore, each second support portion 132 is provided with a guide rail 1321 and a slide block 1322 inside. The guide rail 1321 is disposed on the inner wall of the second support portion 132 along the length direction of the second support portion 132. The slide block 1322 is slidably connected to the inner wall surface of the second support portion 132 and slidably engaged with the guide rail 1321. Based on this, the corresponding micro motor 134 is installed on the slide block 1322, so that the micro motor 134 can follow the relative displacement between the screw 135 and the second support portion 132. In this process, while ensuring the sliding stability of the micro motor 134, the slide block 1322 can limit the axial rotation between the micro motor 134 and the second support portion 132 through its engagement relationship with the guide rail 1321.

[0032] Furthermore, the mating body 12 includes three hinged portions 121 and a first locking member 122. The three hinged portions 121 are evenly distributed at angles to the side surface of the mating body 12 with the geometric central axis of the mating body 12 as the axis. The first locking member 122 is disposed through the side wall of the mating body 12 and abuts against the side surface of the connecting rod 11. Based on this, the mating body 12 is hinged to the top ends of the three first support portions 131 through the three hinged portions 121 respectively. The first locking member 122 is threadedly engaged with the mating body 12, so that the relative position between the mating body 12 and the connecting rod 11 can be locked by rotating the first locking member 122.

[0033] Furthermore, the supporting mechanism 20 includes a first connecting plate 21 and a first rotary motor 22. The bottom surface of the first connecting plate 21 is movably connected to the top of the connecting rod 11. The output end of the first rotary motor 22 is connected to the top surface of the first connecting plate 21, thereby realizing the rotational action between the first rotary motor 22 and the connecting rod 11.

[0034] Furthermore, the support mechanism 20 also includes a second connecting plate 23, a second rotary motor 24, and a mounting base 25. The second rotary motor 24 is connected to the first rotary motor 22 via a linkage assembly; the second connecting plate 23 is connected to the output end of the second rotary motor 24; and the mounting base 25 is connected to the second connecting plate 23. Based on this, the main body of the surveying instrument is mounted on the mounting base 25, thereby enabling the second rotary motor 24 to work in conjunction with the first rotary motor 22 to achieve multi-level rotational adjustment of the surveying instrument.

[0035] Furthermore, a connecting ball head 211 is provided at the bottom of the first connecting plate 21, and correspondingly, a connecting seat 111 is movably provided at the top of the connecting rod 11; the connecting ball head 211 is movably fitted into the top of the connecting seat 111, thereby realizing the movable connection between the first connecting plate 21 and the connecting rod 11.

[0036] Furthermore, in one embodiment, the connecting seat 111 is provided with a second locking member 1111, which is threadedly engaged with the side wall of the connecting seat 111 and abuts against the side surface of the connecting rod 11, thereby achieving locking between the connecting seat 111 and the main body of the connecting rod 11.

[0037] Furthermore, in one embodiment, the engineering surveying device 1 also includes a surveying instrument body (not shown), which is mounted on the mounting base 25 to form the entire engineering surveying device 1.

[0038] In summary, compared to traditional tripods that require manual adjustment of the length of each leg section, the engineering surveying device disclosed in this invention allows for independent and precise automatic extension and retraction of the micro-motors and ball screw mechanisms within the three support legs. The operator only needs to roughly position the tripod, and the system can quickly restore the top support mechanism to a horizontal state by controlling the different strokes of the three motors. This greatly simplifies the setup process in complex terrain and saves significant adjustment time. It also provides a mechanical foundation for the subsequent integration of tilt sensors and control units. Based on the equipment's level or tilt detection system, the three micro-motors can be remotely controlled to extend and retract until the device is horizontal without manual intervention, ensuring adjustment accuracy. Furthermore, the use of ball screws as the transmission core, a high-precision and high-efficiency mechanism that converts rotary motion into linear motion, provides the support legs with self-locking capability and extremely high rigidity.

[0039] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0040] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
