Description

Technical Field

[0001] This utility model relates to the field of surveying tripod technology, specifically a rotatable and telescopic engineering cost surveying tripod. Background Technology

[0002] In on-site surveying operations for engineering cost estimation, the surveying tripod serves as a core auxiliary tool supporting the surveying instrument. Its stability and protection of the surveying instrument directly affect the accuracy of the surveying data and the service life of the equipment.

[0003] Because the clamping force of existing technologies is difficult to control, excessive tightness can easily cause scratches and wear on the surface of the surveying instrument or damage to internal precision components due to vibration, while excessive looseness can easily cause the surveying instrument to slip or shift during operation, affecting the reliability of the surveying data. In addition, when fixing the surveying instrument, it is usually necessary to manually adjust the clamping parts multiple times, such as tightening the bolts one by one, which is a cumbersome and inefficient process. To address these issues, we provide a rotatable and telescopic tripod for on-site engineering cost surveying. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a rotatable and telescopic tripod for on-site engineering cost surveying.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a rotatable and telescopic tripod for on-site engineering cost surveying, comprising a tripod body, an mounting block fixedly connected to the inner wall of the tripod body, and a telescopic rod hinged to the inner side of the mounting block. One end of the telescopic rod is hinged to a telescopic cylinder, and a guide cylinder is movably connected inside the telescopic cylinder. A threaded rod is threadedly connected inside the guide cylinder, and a bevel gear is fixedly connected to the outer wall of the threaded rod. A support platform is movably connected to the outer wall of the threaded rod, and the outer wall of the support platform is hinged to one end of multiple tripod bodies. A bevel gear is arranged inside the support platform, and the bevel gear meshes with the bevel gear. A rotating rod is fixedly connected inside the bevel gear, and a drive rod is fixedly connected to one end of the rotating rod. A rotating mechanism is fixedly connected to the top of the threaded rod, and a rotating platform is rotatably connected to the outside of the rotating mechanism. A worktable is fixedly connected to the top of the rotating platform, and a surveying instrument is arranged on the top of the worktable. A set of symmetrical clamping mechanisms is arranged on the outer wall of the surveying instrument.

[0006] The aforementioned clamping mechanism includes a clamping block, a linkage block, a rolling rod, rollers, and a linkage rod. The bottom end of the clamping block is fixedly connected to the top end of the linkage block, and the interior of the linkage block is rotatably connected to the outer wall of the rolling rod. The two ends of the rolling rod are respectively fixedly connected to the interiors of the two rollers. One end of the linkage block is fixedly connected to one end of the linkage rod.

[0007] As described above, one side of the card block is in contact with the outer wall of the surveying instrument, the roller is rotatably connected to the top surface of the workbench, and a spring is sleeved on the outer wall of the linkage rod.

[0008] As described above, one end of the spring is fixedly connected to one end of the linkage block, and the other end of the spring is fixedly connected to a slider.

[0009] As described above, the interior of the slider is fixedly connected to the outer wall of the linkage rod, and the bottom end of the slider is slidably connected to the top of the worktable. The end of the linkage rod away from the linkage block is movably connected to a fixed block.

[0010] The aforementioned rotating mechanism includes a rotating column, a rotating ring, a limiting ring, a limiting rod, and a driving wheel. The outer side of the rotating column is fixedly connected to the inner wall of the rotating ring, and the outer wall of the rotating column is in close contact with the inner wall of the limiting ring. The inner side of the limiting ring is rotatably connected to one end of the limiting rod, and the other end of the limiting rod is fixedly connected to one end of the driving wheel.

[0011] As described above, the outer walls of the rotating column and the rotating ring are rotatably connected to the interior of the rotating platform, and the interior of the rotating platform is threadedly connected to the outer wall of the limiting rod.

[0012] Compared with existing technologies, this rotatable and telescopic tripod for on-site engineering cost surveying has the following advantages:

[0013] I. This utility model, through its clamping mechanism, pulls down the telescopic cylinder, causing it to drive the telescopic rod to open the tripod body. Then, if it is necessary to fix the surveying instrument, first place the surveying instrument in the groove at the top of the workbench to form an initial clamping position. At this time, two clamping blocks are pressed against both sides of the surveying instrument, causing the clamping blocks to push the linkage block to move. The linkage block then drives the slider to move via the linkage rod, and the roller moves on the workbench with the help of the rolling rod. The spring is then compressed, causing the clamping blocks to elastically clamp the surveying instrument and ultimately fit against its outer wall. This prevents the surveying instrument from slipping during actual operation and ensures data accuracy. Furthermore, the elastic buffer clamping provides a uniform and controllable clamping force on the surveying instrument, preventing surface wear or internal component vibration damage, thereby extending the service life of the surveying instrument.

[0014] II. This utility model, through its rotating mechanism, allows the rotating platform to rotate synchronously with the surveying instrument when the rotating platform is turned, thus adjusting the angle. Once the angle of the surveying instrument is adjusted to the correct position, the driving wheel drives the limiting rod to rotate. The limiting rod then pushes the limiting ring towards the rotating column until the limiting ring is tightly attached to the surface of the rotating column. Since the diameter of the rotating ring is larger than that of the rotating column, the rotating column will not accidentally fall off the rotating platform during rotation, effectively avoiding the problem of accidental rotation and accidental fall of the surveying instrument due to human operation errors, thereby ensuring the accuracy of the surveying data.

[0015] Other advantages, objectives and features of this invention will be set forth in part in the description which follows, and in part will be apparent to those skilled in the art from the following examination or study, or may be taught from the practice of this invention.

Detailed Implementation

[0021] 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.

[0022] like Figure 1-4As shown, this utility model provides a technical solution: a rotatable and telescopic tripod for on-site engineering cost surveying, including a tripod body 1, an mounting block 2 fixedly connected to the inner wall of the tripod body 1, and a telescopic rod 3 hinged to the inner side of the mounting block 2. One end of the telescopic rod 3 is hinged to a telescopic cylinder 4, and a guide cylinder 5 is movably connected inside the telescopic cylinder 4. A threaded rod 6 is threadedly connected inside the guide cylinder 5, and a bevel gear 7 is fixedly connected to the outer wall of the threaded rod 6. A support platform 10 is movably connected to the outer wall of the threaded rod 6, and the outer wall of the support platform 10 is respectively connected to multiple tripods. One end of the tripod body 1 is hinged. The support platform 10 is equipped with a second bevel gear 11, which meshes with a first bevel gear 7. A rotating rod 12 is fixedly connected inside the second bevel gear 11, and a drive rod 13 is fixedly connected to one end of the rotating rod 12. A rotating mechanism 9 is fixedly connected to the top of the threaded rod 6, and a rotating table 14 is rotatably connected to the outside of the rotating mechanism 9. A worktable 15 is fixedly connected to the top of the rotating table 14, and a surveying instrument 16 is installed on the top of the worktable 15. A set of left-right symmetrical clamping mechanisms 8 is provided on the outer wall of the surveying instrument 16.

[0023] First, pull down the telescopic cylinder 4, causing it to drive the telescopic rod 3 to open the tripod body 1. Next, if it is necessary to fix the surveying instrument 16, place the surveying instrument 16 in the groove at the top of the workbench 15 to form an initial clamping position. At this time, the two sides of the surveying instrument 16 press against the two locking blocks 801, causing the locking blocks 801 to push the linkage block 802 to move. Then, the linkage block 802 drives the slider 18 to move via the linkage rod 805, and the roller 804 moves on the workbench 15 with the help of the rolling rod 803. When the spring 17 is compressed, the locking block 801 elastically clamps the surveying instrument 16, ultimately fitting it against its outer wall. This prevents slippage of the surveying instrument 16 during operation and ensures data accuracy. The elastic buffer clamping provides a uniform and controllable clamping force on the surveying instrument 16, preventing surface wear or internal component vibration damage, thus extending its service life. Furthermore, when the rotary table 14 is rotated, it synchronously rotates the surveying instrument 16, adjusting the angle to be measured. After the plotter 16 is adjusted to the correct angle, the drive wheel 905 drives the limit rod 904 to rotate. The limit rod 904 then pushes the limit ring 903 towards the rotating column 901 until the limit ring 903 is tightly fitted against the surface of the rotating column 901. Because the diameter of the rotating ring 902 is larger than that of the rotating column 901, the rotating column 901 will not accidentally detach from the rotary table 14 during rotation. This effectively avoids the problem of the plotter 16 accidentally rotating or detaching due to human error, thus ensuring the accuracy of the surveying data. For accuracy, when adjusting the height of the surveying instrument 16, the drive rod 13 is rotated, which in turn drives the bevel gear 11 to rotate via the rotating rod 12. Since the bevel gear 11 meshes with the bevel gear 7, the bevel gear 7 drives the threaded rod 6 to rotate, and the threaded rod 6 moves up and down within the guide cylinder 5, thereby driving the surveying instrument 16 to move up and down. This allows for flexible adaptation to the height adjustment range requirements of different surveying instruments 16 and meets the compatibility requirements of different models of surveying instruments 16 on the engineering cost site.

[0024] like Figure 1-3As shown, the clamping mechanism 8 includes a clamping block 801, a linkage block 802, a rolling rod 803, a roller 804, and a linkage rod 805. The bottom end of the clamping block 801 is fixedly connected to the top end of the linkage block 802, and the interior of the linkage block 802 is rotatably connected to the outer wall of the rolling rod 803. Both ends of the rolling rod 803 are fixedly connected to the interiors of the two rollers 804, respectively. One end of the linkage block 802 is fixedly connected to one end of the linkage rod 805. One side of the clamping block 801 is in contact with the outer wall of the surveying instrument 16. The roller 804 is rotatably connected to the top surface of the workbench 15. A spring 17 is sleeved on the outer wall of the linkage rod 805. One end of the spring 17 is fixedly connected to one end of the linkage block 802, and the other end of the spring 17 is fixedly connected to a slider 18. The interior of the slider 18 is fixedly connected to the outer wall of the linkage rod 805, and the bottom end of the slider 18 is slidably connected to the top of the workbench 15. A fixing block 19 is movably connected to the end of the linkage rod 805 away from the linkage block 802.

[0025] Pull down the telescopic cylinder 4 to cause it to drive the telescopic rod 3 to open the tripod body 1. Then, if it is necessary to fix the surveying instrument 16, place the surveying instrument 16 in the groove at the top of the workbench 15 to form an initial clamping position. At this time, the two sides of the surveying instrument 16 press against the two locking blocks 801, causing the locking blocks 801 to push the linkage block 802 to move. At this time, the linkage block 802 drives the slider 18 to move through the linkage rod 805, and the roller 804 moves on the workbench 15 with the help of the rolling rod 803. At this time, the spring 17 is compressed, which causes the locking blocks 801 to elastically clamp the surveying instrument 16 and finally fit against its outer wall, preventing the surveying instrument 16 from slipping in actual work and ensuring the accuracy of the data. Moreover, the elastic buffer clamping provides uniform and controllable clamping force on the surveying instrument 16, avoiding surface wear or internal component vibration damage, thereby extending the service life of the surveying instrument 16.

[0026] like Figure 1 , Figure 2 and Figure 4 As shown, the rotating mechanism 9 includes a rotating column 901, a rotating ring 902, a limiting ring 903, a limiting rod 904, and a drive wheel 905. The outer side of the rotating column 901 is fixedly connected to the inner wall of the rotating ring 902, and the outer wall of the rotating column 901 is in close contact with the inner wall of the limiting ring 903. The inner side of the limiting ring 903 is rotatably connected to one end of the limiting rod 904, and the other end of the limiting rod 904 is fixedly connected to one end of the drive wheel 905. The outer walls of the rotating column 901 and the rotating ring 902 are both rotatably connected to the interior of the rotating table 14, and the interior of the rotating table 14 is threadedly connected to the outer wall of the limiting rod 904.

[0027] When the rotary table 14 is rotated, the rotary table 14 will synchronously drive the surveying instrument 16 to rotate, completing the angle adjustment. After the angle of the surveying instrument 16 is adjusted to the correct position, the drive wheel 905 drives the limit rod 904 to rotate. The limit rod 904 then pushes the limit ring 903 to move towards the rotating column 901 until the limit ring 903 is tightly attached to the surface of the rotating column 901. Since the diameter of the rotating ring 902 is larger than that of the rotating column 901, the rotating column 901 will not accidentally fall off the rotary table 14 during the rotation process. This effectively avoids the problem of the surveying instrument 16 accidentally rotating or falling off due to human operation errors, thereby ensuring the accuracy of the surveying data.

[0028] Working principle: First, pull down the telescopic cylinder 4, causing it to drive the telescopic rod 3 to open the tripod body 1. Next, if it is necessary to fix the surveying instrument 16, place the surveying instrument 16 in the groove at the top of the workbench 15 to form an initial clamping position. At this time, the two sides of the surveying instrument 16 press against the two locking blocks 801, causing the locking blocks 801 to push the linkage block 802 to move. At this time, the linkage block 802 drives the slider 18 to move through the linkage rod 805, and the roller 804 moves on the workbench 15 with the help of the rolling rod 803. At this time, the spring 17 is compressed, which causes the locking blocks 801 to elastically clamp the surveying instrument 16 and finally fit against its outer wall. Second, when the rotary table 14 is rotated, the rotary table 14 will synchronously drive the surveying instrument 16 to rotate, completing the angle adjustment. After the angle of the surveying instrument 16 is adjusted to the correct position, the limit rod 904 is driven to rotate by the drive wheel 905. The limit rod 904 then pushes the limit ring 903 to move towards the rotating column 901 until the limit ring 903 is tightly attached to the surface of the rotating column 901. Since the diameter of the rotating ring 902 is larger than that of the rotating column 901, the rotating column 901 will not accidentally fall off the rotating table 14 during rotation. Finally, if the height of the surveying instrument 16 needs to be adjusted, the drive rod 13 is rotated, which drives the bevel gear 11 to rotate through the rotating rod 12. Since the bevel gear 11 meshes with the bevel gear 7, the bevel gear 7 drives the threaded rod 6 to rotate, and the threaded rod 6 moves up and down in the guide cylinder 5, thereby driving the surveying instrument 16 to move up and down.
