Description

Technical Field

[0001] The utility model relates to the technical field of water conservancy engineering surveying and mapping, in particular to a positioning bracket for water conservancy engineering surveying and mapping. Background Art

[0002] Water conservancy projects are projects built to control and allocate natural surface water and groundwater to achieve the purpose of eliminating harm and promoting benefits. They are also called water projects. Water is a valuable resource that is indispensable to human production and life, but its natural state does not fully meet human needs. Only by building water conservancy projects can we control water flows, prevent floods and waterlogging disasters, and regulate and distribute water to meet people's needs for water resources in life and production. Water conservancy projects require the construction of dams, dikes, spillways, sluices, water inlets, channels, ferries, rafts, fishways and other different types of hydraulic structures to achieve their goals. Surveying and mapping instruments are needed for surveying and positioning during construction, and surveying and mapping instruments require brackets for leveling, positioning, support and installation.

[0003] A surveying and mapping instrument surveying and mapping bracket described in publication number CN220828703U includes a supporting circular plate, the top of the supporting circular plate is fixedly connected with a universal tube, the inside of the universal tube is rotatably connected with a universal ball, the top of the universal ball is fixedly connected with a connecting column, the top of the connecting column is fixedly connected with a placement plate, the top of the placement plate is provided with a first sliding groove, the inside of the first sliding groove is slidably connected with a slider, the number of the sliders is two, and the facing surfaces of the sliders are fixedly connected with fixing clamps. When the user installs the surveying and mapping instrument, the connecting column can be rotated to drive the universal ball to adjust the angle in the universal tube. When it is adjusted to a suitable angle, the user can place the surveying and mapping instrument on the placement plate and pull the fixing clamp inward, so as to clamp and fix surveying and mapping instruments of different sizes, thereby facilitating the user to quickly install the surveying and mapping instrument and improving work efficiency.

[0004] Although the above bracket solves certain problems, it still has the following disadvantages:

[0005] (1) The bracket is supported by three independent support rods. When installing and placing, the support rods need to be opened one by one, and the support and stability are achieved through the friction between the lower end of the support rod and the ground. The installation is more troublesome and the stability is poor.

[0006] (2) The bracket is troublesome to level the instrument, and the instrument cannot be accurately leveled, which affects the accuracy of surveying and mapping. Utility Model Content

[0036] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. Instead, they are merely examples of devices consistent with some aspects of the present disclosure as detailed in the appended claims.

[0037] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0038] Embodiment 1:

[0039] like Figures 1 to 7 As shown, this embodiment proposes a positioning bracket for water conservancy engineering surveying and mapping, including a tripod 1, a column 2, a mounting groove 10, a telescopic rod 11, a mounting rod 8, a linkage assembly 3, a limiting mechanism 4, a locking assembly 5 for positioning the telescopic rod 11, and a support assembly 6 installed at the lower end of the telescopic rod 11.

[0040] The tripod 1 is used as a base for installing the surveying instrument. A column 2 is hinged on the three outer sides of the tripod 1. A mounting groove 10 is provided at the other end of the column 2 connected to the tripod 1. A telescopic rod 11 is provided inside the mounting groove 10. The telescopic rod 11 can be extended and retracted from the inside of the mounting groove 10 to adjust the length of the overall foot support of the bracket. In order to facilitate the positioning of the telescopic rod 11, a connecting hole 13 is provided at the outer lower end of the column 2 away from the tripod 1. Each connecting hole 13 is provided inside A bolt 502 is provided, and the bolt 502 is connected to the internal thread of the connecting hole 13 together. One end of the bolt 502 is inserted into the interior of the mounting groove 10 through the connecting hole 13, and an extrusion friction plate 501 is fixedly connected to the end of the bolt 502 inserted into the interior of the mounting groove 10. By rotating the bolt 502, the extrusion friction plate 501 squeezes the surface of the telescopic rod 11, and the telescopic rod 11 is positioned by a sufficiently large friction force. The telescopic rod 11 is adjusted by turning the bolt 502, which increases the convenience of adjusting the height of the bracket.

[0041] In order to prevent the telescopic rod 11 from falling off from the inside of the installation groove 10, a limit block 401 is fixedly connected to the lower ends of both sides inside the installation groove 10, and a limit groove 402 for cooperating with the limit block 401 is opened on both sides of the telescopic rod 11. The limit groove 402 is opened at one end in the middle of both sides of the telescopic rod 11, and a certain distance is left at both ends, so that the telescopic rod 11 can only move up and down inside the installation groove 10 along the limit block 401 through the limit groove 402, and the upper and lower ends inside the limit groove 402 are fitted with the limit block 401, so that the telescopic rod 11 can only move up and down within a certain distance.

[0042] In order to enable the three columns 2 to expand outward or contract inward synchronously, a mounting rod 8 is fixedly connected to the lower end of the tripod 1, and a lifting ring 301 is sleeved on the outside of the mounting rod 8. The lifting ring 301 moves up and down along the outside of the mounting rod 8. The lifting ring 301 and the three columns 2 are connected together by three evenly distributed connecting rods 302. The two ends of the connecting rod 302 are respectively hinged to the side of the outside of the column 2 that is close to each other and to the outer wall of the lifting ring 301. When the column 2 expands outward, the lifting ring 301 will move downward. As the lifting ring 301 moves downward, the other two connecting rods 302 will support the other two columns 2 outward, allowing the three columns 2 to expand outward synchronously, making it convenient to quickly install and store the bracket.

[0043] Embodiment 2:

[0044] The solution in Example 1 is further introduced below in combination with a specific working method, as described below:

[0045] In order to keep the bottom and the surveying location stable after the telescopic rod 11 is extended and retracted and the column 2 is unfolded, a connecting groove 12 is opened at the lower end of the telescopic rod 11, and a damping rubber sheet 602 is fixedly connected to both sides of the interior of the connecting groove 12, and a foot 601 is arranged at the lower end of the telescopic rod 11, and a circular hole is opened on the upper side of the foot 601, and the sides of the upper ends of the outer ends of the foot 601 that are close to each other are hinged together with the interior of the connecting groove 12, and the foot 601 is squeezed by the damping rubber sheets 602 on both sides, and the friction force generated by the damping rubber sheets 602 is used to provide damping, so as to position the rotation of the foot 601, so as to facilitate the inclination adjustment of the tripod 1 through the extension and retraction of the telescopic rod 11 inside different columns and through the angle of the foot 601, and a support column 603 is threadedly connected to the hole opened in the foot 601, and the support column 603 is used to fix the column 2 and the telescopic rod 11 to prevent the bracket from shaking at will.

[0046] The tripod 1 is observed by three universal bubble levels 14 fixedly connected around the upper side of the tripod 1 to determine whether the bracket is leveled. When the bubbles inside the three universal bubble levels 14 are centered, it means that the bracket has been leveled. The telescopic rod 11 inside the column 2 facing the corresponding universal bubble level 14 is extended outward to the direction where the bubble is biased, and then the foot 601 at the lower end of the telescopic rod 11 is rotated to be parallel to the ground to ensure support. The up and down movement of the lifting ring 301 is limited by the baffle 9 installed at the lower end of the mounting rod 8. A laser pen 15 is installed at the lower end of the baffle 9. The laser pen is used to illuminate the surveying point to facilitate vertex surveying. When the column is opened, ensure that the lower side of the lifting ring 301 and the upper side of the baffle 9 are fitted together, so that the column 2 is fully opened to ensure the stability of the bracket. When the column is folded, the upper end of the lifting ring 301 is fitted with the lower side of the tripod 1 to ensure that the column 2 is fully retracted.

[0047] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
