Description

Technical Field

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

[0002] In road construction, the accuracy and efficiency of measurement and positioning directly affect the construction quality. RTK real-time dynamic positioning technology, with its centimeter-level high precision, has become a core technical support for construction layout, topographic mapping, and other processes, and is widely used in infrastructure construction such as highways and bridges. Currently, RTK measuring instruments are mainly used in two scenarios: fixed measurement requires the use of a tripod to ensure positioning stability; handheld mobile measurement relies on a centering rod, which allows for flexible operation by staff to adapt to diverse on-site work needs. However, in actual construction, measurement tasks often require frequent switching between fixed and mobile modes depending on site conditions. This necessitates repeated disassembly and assembly of the tripod and centering rod. The overall operation is quite cumbersome, causing inconvenience to personnel's daily work and increasing the time required for measurement preparation, thereby affecting the efficiency of the measurement operation. Utility Model Content

[0003] The purpose of this utility model is to provide a road engineering measurement locator that allows personnel to quickly disassemble and switch the support method according to actual needs. It is easy and quick to operate, bringing great convenience to the measurement work of personnel.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a road engineering surveying and positioning device, comprising a fixed base, a support foot hinged to the lower end of the outer surface of the fixed base via a pin, a column slidably connected to the lower end of the inner cavity of the fixed base, a strut hinged between the lower end of the column and the middle end of the support foot via a pin, a rod placed between the inner cavity of the fixed base and the top of the column, a movable rod placed in the inner cavity of the rod, an RTK measuring instrument fixedly mounted on the top of the movable rod, positioning blocks fixedly connected to the lower ends of both sides of the outer surface of the rod, an annular groove provided at the upper end of the outer surface of the fixed base, a rotating sleeve movably sleeved at the upper end of the outer surface of the fixed base, the top of the positioning block contacting the top of the inner cavity of the rotating sleeve, through holes provided at both ends of the top of the rotating sleeve, and a torsion spring fixedly installed between the lower end of the inner cavity of the rotating sleeve and the bottom of the annular groove.

[0005] As a preferred embodiment, both sides of the inner cavity of the support foot are provided with sliding grooves, and an adjusting rod is slidably connected between the surfaces of the two sliding grooves. The lower end of the support foot is threadedly connected with a first locking bolt, and the lower end of the first locking bolt contacts the surface of the adjusting rod.

[0006] As a preferred embodiment, the upper end of the right side of the rod is threaded with a second locking bolt, and the left side of the second locking bolt contacts the surface of the movable rod.

[0007] As a preferred embodiment, an annular plate is fixedly connected to the middle end of the inner cavity of the rotating sleeve, and the top of the annular plate contacts the top of the annular groove.

[0008] As a preferred embodiment, the outer surface of the rotating sleeve is provided with anti-slip ridges.

[0009] As a preferred embodiment, positioning grooves are provided at the upper ends of both sides of the inner cavity of the fixed seat, and the surface of the positioning block is slidably connected to the surface of the positioning groove.

[0010] As a preferred embodiment, the number of supporting legs and struts is three.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] This invention, through the design of a torsion spring, a rotating sleeve, a positioning block, and a through hole, facilitates quick installation and disassembly of the rod and the fixed base. When the RTK measuring instrument needs to be handheld, the rotating sleeve can be rotated to align the through hole with the positioning block, allowing the rod to be removed from the fixed base for handheld movement via the rod and movable rod. When the RTK measuring instrument needs to be placed, the rod can be inserted back into the fixed base, and the rotating sleeve will rotate and reset under the action of the torsion spring, causing the through hole and positioning block to be misaligned, thus completing the installation of the rod and the fixed base. During the installation of the rod, it provides support to the top of the column, and the column and support rod together cause the three sets of support legs to open and form a triangular support with the ground, facilitating the placement of the entire instrument. The overall operation is convenient and quick, allowing personnel to quickly switch between different support modes as needed. Attached Figure Description

Detailed Implementation

[0019] 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.

[0020] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0021] The components in this application, such as the fixed base 1, rod 2, RTK measuring instrument 3, support foot 4, slide groove 5, adjusting rod 6, first locking bolt 7, column 8, support rod 9, rotating sleeve 10, through hole 11, movable rod 12, second locking bolt 13, positioning block 14, positioning groove 15, annular groove 16, torsion spring 17, and annular plate 18, are all general standard parts or parts known to those skilled in the art. Their structure and principle are common knowledge and can be learned by those skilled in the art through technical manuals or conventional experimental methods.

[0022] Example 1:

[0023] Please see Figures 1-5As shown, this utility model provides a road engineering measurement locator, including a fixed base 1. The lower end of the outer surface of the fixed base 1 is hinged to a support foot 4 by a pin. The lower end of the inner cavity of the fixed base 1 is slidably connected to a column 8. The lower end of the column 8 and the middle end of the support foot 4 are hinged to a support rod 9 by a pin. A rod body 2 is placed between the inner cavity of the fixed base 1 and the top of the column 8. A movable rod 12 is placed in the inner cavity of the rod body 2. An RTK measuring instrument 3 is fixedly installed on the top of the movable rod 12. Positioning blocks 14 are fixedly connected to the lower ends of both sides of the outer surface of the rod body 2. An annular groove 16 is provided at the upper end of the outer surface of the fixed base 1. A rotating sleeve 10 is movably sleeved at the upper end of the outer surface of the fixed base 1. The top of the positioning block 14 contacts the top of the inner cavity of the rotating sleeve 10. Through holes 11 are provided at both ends of the top of the rotating sleeve 10. A torsion spring 17 is fixedly installed between the lower end of the inner cavity of the rotating sleeve 10 and the bottom of the annular groove 16.

[0024] In this technical solution, the fixed base 1, the rod 2, and the movable rod 12 provide support for the RTK measuring instrument 3 during use. Simultaneously, the rotating sleeve 10, in conjunction with the positioning block 14, limits the movement between the rod 2 and the fixed base 1, preventing the rod 2 from detaching from the fixed base 1. Furthermore, the rod 2 limits the top of the column 8 during installation. With the support of the column 8 and the support rod 9, the support legs 4 at the lower end of the fixed base 1 can be opened, allowing the entire unit to be placed on the ground in a triangular support configuration. When hand-held movement is required, the rotating sleeve 10 can be rotated. While the torsion spring 17 in the annular groove 16 is being pressed, the rotating sleeve 10 rotates, causing the through hole 11 to rotate until the through hole 11 is above the positioning block 14. Then, the operator can remove the rod 2 from the fixed base 1. The operator can then use the rod 2 and the movable rod 12 to move the RTK measuring instrument 3 by hand. During the removal of the rod 2 from the fixed base 1, the limit at the top of the column 8 disappears. Then, the operator can push the support foot 4 to rotate. The support rod 9 pushes the column 8 upward until the three sets of support feet 4 can be vertically stored, which greatly facilitates the operator's carrying and working.

[0025] It should be noted that during use, personnel can additionally install a bubble level on rod 2 for leveling purposes.

[0026] Example 2:

[0027] Based on Embodiment 1, this utility model is as follows: Figures 1-5As shown, the inner cavity of the support foot 4 is provided with sliding grooves 5 on both sides, and an adjusting rod 6 is slidably connected between the surfaces of the two sliding grooves 5. The lower end of the support foot 4 is threadedly connected with a first locking bolt 7, and the lower end of the first locking bolt 7 contacts the surface of the adjusting rod 6. The upper end of the right side of the rod body 2 is threadedly connected with a second locking bolt 13, and the left side of the second locking bolt 13 contacts the surface of the movable rod 12. The middle end of the inner cavity of the rotating sleeve 10 is fixedly connected with an annular plate 18, and the top of the annular plate 18 contacts the top of the annular groove 16. The outer surface of the rotating sleeve 10 is provided with anti-slip ridges. The upper ends of both sides of the inner cavity of the fixed seat 1 are provided with positioning grooves 15, and the surface of the positioning block 14 is slidably connected to the surface of the positioning groove 15. There are three support feet 4 and three support rods 9.

[0028] In this technical solution, the sliding groove 5, adjusting rod 6, and first locking bolt 7 allow personnel to pull the adjusting rod 6 along the surface of the sliding groove 5 during use, and use the first locking bolt 7 to lock and fix the adjusting rod 6 and the support foot 4, so that personnel can adjust the support height of each set of support feet 4 according to their needs. The second locking bolt 13 allows personnel to adjust the support height between the rod body 2 and the movable rod 12. The annular plate 18 limits the movement between the rotating sleeve 10 and the annular groove 16, preventing the rotating sleeve 10 from coming loose from the upper end of the fixed seat 1. The positioning groove 15 accommodates and positions the positioning block 14, preventing the positioning block 14 from rotating with the rod body 2.

[0029] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit the scope of protection of this utility model. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the essence and scope of the technical solutions of this utility model.
