Description

Technical Field

[0001] This utility model belongs to the field of water conservancy engineering surveying technology, specifically a new type of water conservancy engineering surveying support frame. Background Technology

[0002] During the construction of water conservancy projects, surveying instruments are usually used, and these instruments are used in conjunction with support frames.

[0003] Utility model patent CN211203332U discloses a novel support frame for water conservancy engineering surveying. It solves the problem that traditional support frames are mostly assembled, requiring workers to assemble and set up the measuring instruments, and then disassemble them when not in use. They cannot be extended or retracted, making them inconvenient for workers and causing inconvenience. Furthermore, they cannot be adjusted according to terrain or angles from multiple directions to ensure optimal performance and ease of use. However, this new design utilizes a second spring and a limiting plate. The second spring compresses the limiting plate to secure the measuring instrument. While this method is simple and can secure measuring instruments of different sizes, in practice, when the instrument is narrow, the compression of the second spring is small, resulting in less spring force and less pressure between the limiting plate and the instrument, making stable fixation impossible. Utility Model Content

[0004] To address the problems mentioned in the background art, the purpose of this utility model is to provide a new type of hydraulic engineering surveying support frame, which has the advantages of good fixing effect and ease of use.

[0005] This utility model provides the following technical solution: A novel hydraulic engineering surveying support frame, comprising a support plate, a lifting and adjusting assembly on the top of the support plate, a movable plate above the support plate, a rotating adjusting assembly on the top of the movable plate, a fixed platform above the rotating adjusting assembly, a sliding groove on the top of the fixed platform, and sliders slidably connected to both sides of the sliding groove. A threaded rod with both positive and negative threads is rotatably connected inside the sliding groove, and the threaded rod is threadedly connected to the slider. The right side of the threaded rod extends to the right side of the fixed platform and is fixedly connected to a first rotating handle. A fixed plate is fixedly connected to the top of the slider. The internal sliding connection includes four first limiting rods. A clamping plate is fixedly connected to the surface of each first limiting rod. A compression spring is fixedly connected to the surface of the clamping plate. The end of the compression spring away from the clamping plate is fixedly connected to the clamping plate. The surface of the compression spring is coated with anti-rust paint. A groove is provided on the surface of the clamping plate, and a sliding groove is provided on the inner wall of the groove. An extension plate is slidably connected inside the sliding groove. The extension plate is slidably connected to the clamping plate. A fixing block is fixedly connected to the top of the clamping plate. A first threaded rod is threadedly connected inside the fixing block. A second rotating handle is fixedly connected to the surface of the first threaded rod. The first threaded rod is in contact with the extension plate.

[0006] The beneficial effects of this utility model are as follows:

[0007] 1. This utility model places the measuring instrument between two clamping plates. By rotating the first handle, the positive and negative threaded rods are rotated, which in turn causes the sliders and fixing plates on both sides to move closer to each other, and then causes the clamping plates on both sides to move closer to each other. When the clamping plates are in contact with the sides of the measuring instrument, the fixing plates on both sides are further adjusted to move closer to each other, thereby reducing the distance between the fixing plates and the clamping plates, and thus compressing the compression spring. Under the action of the compression spring, the clamping plates are tightly attached to the measuring instrument, thereby improving the stability of fixing the measuring instrument.

[0008] 2. With the lifting and adjusting component, the operator can rotate the cylinder. Since the second threaded rod is threadedly connected to the cylinder and fixedly connected to the movable plate, the second threaded rod moves up or down when the cylinder rotates, thereby finely adjusting the height of the movable plate, the rotating shaft and the fixed platform, and thus adjusting the height of the measuring instrument on the top of the fixed platform.

[0015] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0016] like Figures 1 to 6 As shown, the novel hydraulic engineering surveying support frame of this embodiment includes a support plate 1, a lifting adjustment component 2 on the top of the support plate 1, a movable plate 3 above the support plate 1, a rotation adjustment component 4 on the top of the movable plate 3, a fixed platform 5 above the rotation adjustment component 4, a slide groove on the top of the fixed platform 5, and sliders 6 slidably connected to both sides inside the slide groove. A threaded rod with positive and negative threads is rotatably connected inside the slide groove and threaded to the sliders 6. The right side of the threaded rod extends to the right side of the fixed platform 5 and is fixedly connected to a first rotating handle. A fixed plate 7 is fixedly connected to the top of the sliders 6, and a first limiting mechanism is slidably connected inside the fixed plate 7. The number of first limiting rods 8 is four. A clamping plate 9 is fixedly connected to the surface of the first limiting rod 8. A compression spring 10 is fixedly connected to the surface of the fixing plate 7. The end of the compression spring 10 away from the fixing plate 7 is fixedly connected to the clamping plate 9. The surface of the compression spring 10 is sprayed with anti-rust paint. The surface of the clamping plate 9 is provided with a groove, and the inner wall of the groove is provided with a sliding groove. An extension plate 11 is slidably connected inside the sliding groove. The extension plate 11 is slidably connected to the clamping plate 9. A fixing block 12 is fixedly connected to the top of the clamping plate 9. A first threaded rod 13 is threadedly connected inside the fixing block 12. A second rotating handle is fixedly connected to the surface of the first threaded rod 13. The first threaded rod 13 is in contact with the extension plate 11.

[0017] refer to Figure 1 and Figure 6 The lifting adjustment assembly 2 includes a second limiting rod 14 slidably connected inside the support plate 1. There are three second limiting rods 14. A cylinder 15 is rotatably connected to the top of the support plate 1. A second threaded rod 16 is threadedly connected inside the cylinder 15. The top of the second threaded rod 16 is fixedly connected to the bottom of the movable plate 3. Anti-slip strips are fixedly connected to the surface of the cylinder 15. There are several anti-slip strips, and the anti-slip sleeves are evenly distributed in a ring on the surface of the cylinder 15.

[0018] In this embodiment, by setting up the lifting adjustment component 2, the operator can rotate the cylinder 15. Since the second threaded rod 16 is threadedly connected to the cylinder 15 and fixedly connected to the movable plate 3, when the cylinder 15 rotates, the second threaded rod 16 moves up or down, thereby finely adjusting the height of the movable plate 3, the rotating shaft 17 and the fixed platform 5, and thus adjusting the height of the measuring instrument on the top of the fixed platform 5.

[0019] refer to Figure 1 and Figure 3 The rotary adjustment assembly 4 includes a rotating shaft 17 rotatably connected to the top of the movable plate 3. The top of the rotating shaft 17 is fixedly connected to the bottom of the fixed platform 5. A worm gear 18 is sleeved on the surface of the rotating shaft 17. Support blocks 19 are fixedly connected to both sides of the top of the movable plate 3. A worm 20 is rotatably connected inside the support block 19. The worm 20 meshes with the worm gear 18. A third rotating handle is fixedly connected to the right side of the worm 20.

[0020] In this embodiment, by setting the rotation adjustment component 4, the operator can rotate the worm 20 to drive the worm wheel 18 to rotate, which in turn drives the rotating shaft 17 to rotate, which in turn drives the fixed platform 5 and the measuring instrument on the top of the fixed platform 5 to rotate, thereby adjusting the angle of the measuring instrument on the top of the fixed platform 5.

[0021] refer to Figure 1 , Figure 4 and Figure 6 A positioning block 21 is fixedly connected to the surface of the support plate 1. A hinge block 22 is hinged inside the positioning block 21. A disc 23 is fixedly connected to the surface of the hinge block 22. A first through-hole 24 is opened on the surface of the disc 23. There are several first through-holes 24. The first through-holes 24 are evenly distributed in a ring on the surface of the disc 23. A third threaded rod 25 is threaded inside the positioning block 21. The third threaded rod 25 is movably connected to the first through-hole 24. A fourth rotating handle is fixedly connected to the surface of the third threaded rod 25.

[0022] In this embodiment, by setting up a positioning block 21, a hinge block 22, a disc 23, a first through-hole 24, and a third threaded rod 25, the operator can rotate the hinge block 22 to adjust its angle, thereby adjusting the tilt angle of the sleeve 26. When the hinge block 22 is adjusted to a suitable angle, the rotation of the hinge block 22 causes the disc 23 on its surface to rotate. By passing one end of the third threaded rod 25 through the first through-hole 24 and threadedly connecting it to the positioning block 21, the disc 23 is limited to prevent it from rotating, thereby preventing the hinge block 22 from rotating.

[0023] refer to Figure 1 and Figure 6The bottom of the hinge block 22 is fixedly connected to a sleeve 26. The inside of the sleeve 26 is slidably connected to a movable column 27. The surface of the movable column 27 is provided with a second through-hole 28. There are several second through-holes 28. The inside of the sleeve 26 is threadedly connected to a fourth threaded rod 29. The fourth threaded rod 29 is inserted into the second through-hole 28. The surface of the fourth threaded rod 29 is fixedly connected to a fifth rotating handle.

[0024] In this embodiment, with the sleeve 26, movable column 27, second port 28 and fourth threaded rod 29, the operator can adjust the position of movable column 27, thereby adjusting the height of the device, and thus making a rough adjustment of the height of the device. By tightening the fourth threaded rod 29, the fourth threaded rod 29 is inserted into the second port 28, thereby locking the position of movable column 27.

[0025] refer to Figure 1 The surface of the movable column 27 is hinged to a base plate 30, and the interior of the base plate 30 is slidably connected to a positioning rod 31.

[0026] In this embodiment, by setting up the base plate 30 and the positioning rod 31, the base plate 30 can increase the contact area between the movable column 27 and the ground, and the positioning rod 31 can be inserted into the ground, thereby preventing the device from shifting and improving the stability of the device.

[0027] This invention places the measuring instrument between two clamping plates 9. By rotating the first handle, the positive and negative threaded rods are rotated, which in turn causes the sliders 6 and the fixing plates 7 on both sides to move closer to each other, which in turn causes the clamping plates 9 on both sides to move closer to each other. When the clamping plates 9 are in contact with the sides of the measuring instrument, the fixing plates 7 on both sides are adjusted to move closer to each other, thereby reducing the distance between the fixing plates 7 and the clamping plates 9, and thus compressing the compression spring 10. Under the action of the compression spring 10, the clamping plates 9 are tightly attached to the measuring instrument, thereby improving the stability of fixing the measuring instrument.

[0028] When fixing measuring instruments of any width, this device allows adjustment of the compression amount of the spring 10, thus ensuring stable fixation of the measuring instruments. Furthermore, the device is simple to operate; simply rotating the first handle with one hand adjusts the clamping plates 9 on both sides to bring them closer together. The device can also adjust the height of the extension plate 11 according to the height of the measuring instrument, thereby improving the stability of fixing the measuring instrument. For example, when the measuring instrument is high, the operator can pull the extension plate 11 upwards to move it to a suitable height. By rotating the first threaded rod 13, the first threaded rod 13 is brought into close contact with the extension plate 11, thus positioning the extension plate 11.
