Description

Technical Field

[0001] This utility model relates to the field of engineering surveying auxiliary equipment technology, specifically to a support frame device for field surveying engineering. Background Technology

[0002] In field surveying projects, it is often necessary to use support frames to hold surveying instruments such as total stations and levels, as well as auxiliary supplies such as drawings, recording boards, and surveying tools. Existing support frames generally have the following problems:

[0003] Firstly, conventional support structures have a single function, only suitable for setting up instruments. Surveyors often need to record data, view drawings, draw sketches, or use various hand tools on-site. These activities usually require finding or carrying a simple platform, which is quite inconvenient. Secondly, the terrain in the field is rugged and uneven. Traditional support frames lack effective shock absorption structures, making surveying instruments susceptible to ground vibrations during operation, leading to a decrease in measurement accuracy. Thirdly, the workbench and support structure are fixed as one piece, making it impossible to flexibly disassemble or adjust according to operational needs. Furthermore, conventional workbenches lack effective design for securing drawings and storing tools, resulting in limited practicality.

[0004] To address the aforementioned technical problems, this utility model proposes an integrated, multifunctional, and structurally stable field surveying engineering support device, aiming to improve the convenience of field surveying operations. Utility Model Content

[0005] This invention aims to overcome the shortcomings of existing technologies and provide a support frame device for field surveying engineering. This device not only stably supports surveying instruments but also allows for flexible disassembly, providing a workbench with functions such as drawing fixation, tool storage, and shock absorption, thus solving problems such as the lack of work platforms and shock absorption capabilities in field operations.

[0006] To solve the above-mentioned technical problems, the present invention provides a support frame device for field surveying engineering: comprising a support assembly and a worktable assembly; the support assembly includes a base plate, a tripod, a support rod, a support plate, and a shock-absorbing spring; the tripod is rotatably connected to the bottom of the base plate; the lower end of the support rod is connected to the base plate, and the upper end is connected to the support plate; the support rod has an axial through hole inside; the shock-absorbing spring is sleeved on the outside of the support rod in a pre-compressed state, and its two ends are respectively connected to the base plate and the support plate;

[0007] The workbench assembly includes a connecting rod, a work plate, and at least one mesh bag. The lower part of the connecting rod has a threaded hole, and a pad is fixed to its upper part. The diameter of the pad is larger than the diameter of the connecting rod. The connecting rod can pass through the through hole of the support rod from bottom to top and is fastened to the support assembly by a fixing bolt that mates with the threaded hole at the bottom of the connecting rod. At this time, the lower surface of the pad is in contact with the upper surface of the support plate. The work plate is fixedly installed above the pad. The upper surface of the work plate is a magnetic plate. The at least one mesh bag is disposed on the lower surface of the work plate.

[0008] In some embodiments of the present invention, the workbench assembly further includes a plurality of magnets that can be attached to the magnetic surface of the workbench.

[0009] In some embodiments of this utility model, the magnetic plate surface of the working plate is covered with a scratch-resistant protective layer.

[0010] In some embodiments of this utility model, the upper surface of the support plate is provided with anti-slip texture or anti-slip pad.

[0011] In some embodiments of this utility model, the number of nets is two or more, and they are symmetrically arranged on the lower surface of the working plate.

[0012] In some embodiments of this utility model, the connecting rod and the pad are integrally formed.

[0013] In some embodiments of this utility model, the support rod is detachably connected to the base plate and / or the support plate.

[0014] In some embodiments of this utility model, the tripod legs are multi-section telescopic sleeve structures, and their length is locked and released by a locking knob.

[0015] The advantages of this invention compared to existing technologies are as follows: It integrates the instrument tripod structure with the surveying auxiliary workbench, allowing surveyors to obtain a stable work area using the shock-absorbing tripod support structure, effectively improving the efficiency and convenience of fieldwork. The shock-absorbing springs effectively isolate low-frequency vibrations caused by uneven ground, personnel movement, or wind, ensuring the stability of the surveying instrument or work surface and guaranteeing the quality of fieldwork results. The magnetic workbench, with its magnetic stickers, effectively secures drawings of various sizes and resists wind damage. A mesh pocket under the board provides dedicated storage space for small tools such as screwdrivers, measuring tapes, and markers, preventing tools from scattering, being lost, or getting dirty, keeping the work site clean and orderly. The workbench assembly can be quickly assembled and disassembled from the support assembly via connecting rods and fixing bolts. When the workbench is not needed, the support assembly can be used alone to set up the instrument; when needed, it can be quickly assembled, making the entire device easy to carry and transport in the field.

[0024] To facilitate understanding of this application, a more complete description will be provided below with reference to the accompanying drawings, which illustrate embodiments of the present application. However, the present application can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that the disclosure of this application will be thorough and complete.

[0025] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.

[0026] like Figure 1-6As shown, a support frame device for field surveying engineering includes a support assembly and a workbench assembly.

[0027] In some embodiments of this utility model, such as Figure 1 As shown, the support assembly includes a circular metal base plate 1. A conventional tripod 2 is rotatably connected to the base plate 1 via a central hinge seat. Each leg of the tripod 2 is composed of three sections of aluminum tubing joined together. The length can be adjusted and locked by rotating the locking knob 21. The three legs are evenly distributed to ensure support stability. A metal tube serving as a support rod 3 is vertically welded and fixed to the center of the base plate 1, and a circular support plate 4 is welded and fixed to its top. The support rod 3 is detachably connected to the base plate 1 and / or the support plate 4, specifically using threaded or snap-fit ​​connections, facilitating disassembly, transportation, and maintenance / replacement of components. The support rod 3 is a hollow tube, and its inner cavity forms an axial through hole 31, such as... Figure 4 and Figure 5 As shown. The upper surface of the support plate 4 is provided with anti-slip textures or anti-slip pads. The anti-slip pads are made of rubber or silicone material and are fixed to the support plate 4 by adhesive, increasing the friction between the pad 61 and the support plate 4 and preventing the workbench assembly from sliding during operation. Figure 1 As shown, a stainless steel compression spring 5 is fitted around the support rod 3, with its lower end abutting the base plate 1 and its upper end abutting the support plate 4. In its natural state, it has a certain amount of pre-compression, forming an elastic support. During use, the spring absorbs vibration energy through elastic deformation, thus achieving the function of shock absorption and buffering.

[0028] In some embodiments of this utility model, such as Figure 4 and Figure 5 As shown, the workbench assembly includes a connecting rod 6, a rectangular work plate 7, and two mesh bags 8. The connecting rod 6 is a round steel rod with a screw hole 62 machined at its lower center, and its upper part is welded to a disc-shaped steel pad 61 to form an integral structure. The diameter of the pad 61 is larger than the diameter of the connecting rod 6, forming a limiting support structure. The connecting rod 6 can pass through the through hole 31 of the support rod 3 from bottom to top, and is fastened to the support assembly by a fixing bolt 9 that mates with the screw hole 62 at the lower part of the connecting rod 6. At this time, the lower surface of the pad 61 is in close contact with the upper surface of the support plate 4, and the workbench assembly and the support assembly are firmly connected by bolt locking.

[0029] In some embodiments of this utility model, the working board 7 adopts a composite structure of a metal backing plate and a magnetic soft whiteboard. The surface of the magnetic board is covered with a transparent, scratch-resistant PET protective film, which prevents the magnetic board surface from being scratched by surveying tools without affecting the magnetic adsorption effect. For example... Figure 3As shown, the worktable 7 is fixed to the upper surface of the pad 61 by bolts. Two or more mesh bags 8 are symmetrically arranged on the lower surface of the worktable 7. The mesh bags 8 are made of wear-resistant nylon cloth or canvas, with reinforced stitching along the edges and an elasticated bottom design. They can be used to categorize and store small tools such as screwdrivers, measuring tapes, markers, and spare batteries, preventing them from being scattered or lost. They are also used to store small surveying tools. As a preferred embodiment of this invention, the workbench assembly also includes multiple magnets 10. The magnets 10 are circular or rectangular permanent magnets that can firmly adhere to the magnetic surface of the worktable 7. Through the attraction between the magnets 10 and the magnetic surface, drawings and recording papers of different sizes can be fixed to the worktable 7, effectively resisting wind in the field.

[0030] Assembly and usage process:

[0031] When only surveying instrument 11 needs to be set up, such as Figure 6 As shown, the instrument can be directly mounted on the support plate 4 via its base. The support plate 4, with the cushioning effect of the shock-absorbing spring 5, effectively filters out minor vibrations from the ground, providing a stable platform for the instrument.

[0032] When operators need to draw, record, or frequently use tools, the workbench assembly is installed. During installation, first, with the end of the connecting rod 6 containing the pad 61 facing upwards, pass the connecting rod 6 through the through hole 31 inside the support rod 3 from below. Figure 4 , Figure 5 As shown, continue until the lower surface of the pad 61 is completely resting on the anti-slip pad of the support plate 4. Then, screw the fixing bolt 9 in from below the base plate 1, tightening it into the screw hole 62 at the center of the lower part of the connecting rod 6. During tightening, the head of the fixing bolt 9 pulls the connecting rod 6, pressing the pad 61 against the support plate 4, thereby firmly fixing the workbench assembly to the top of the support assembly, as shown. Figure 1 As shown.

[0033] After installation, the user can lay the survey drawing flat on the magnetic surface of the work board 7 and secure it firmly with multiple magnets 10. Pens, rulers, calculators, small tools, etc., can be placed in the mesh pockets 8 on both sides. The entire device integrates support, shock absorption, work, and storage functions, facilitating comprehensive field surveying operations.

[0034] After the work is completed, unscrew the fixing bolt 9 in the opposite direction to remove the entire workbench assembly. It can then be stored and transported separately from the support assembly, making it flexible and convenient.

[0035] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
