Description

Technical Field

[0001] This utility model belongs to the field of engineering geological surveying and mapping technology, and in particular relates to an auxiliary device for engineering geological surveying and mapping. Background Technology

[0002] Geological mapping is the science and technology of systematically recording and mapping the geological features of the Earth's surface and subsurface through field investigations, data collection, and analysis. Its core objective is to construct geological maps, revealing the distribution and interrelationships of geological elements such as strata, rocks, structures, and minerals, providing fundamental data for resource development, disaster prevention, and engineering construction.

[0003] In geological surveying engineering, surveying instruments are frequently used. These instruments require a surveying tripod for support to ensure they remain level during surveying, making the images easier to observe. However, in areas with sandy soil or uneven terrain such as hillsides, it is difficult to keep the surveying tripod level. Existing surveying tripods typically require repeated adjustments to maintain levelness, which is cumbersome. Utility Model Content

[0004] In view of the above situation and to overcome the shortcomings of the existing technology, the purpose of this utility model is to provide an auxiliary device for engineering geological surveying, which effectively solves the problem of cumbersome operation.

[0005] The technical solution to the technical problem is as follows: it includes a surveying instrument, a gimbal, and a leg assembly. The leg assembly includes a support plate, the gimbal is installed above the support plate, and multiple brackets are evenly hinged around the lower circumference of the support plate. A sleeve is fixed to the other end of the bracket, and a leg is slidably connected inside the sleeve. A base is hinged to the other end of the leg, and a cone is fixed to the lower end of the base. A protective sleeve is threaded to the lower end of the base, and the cone is located inside the protective sleeve. A vertical lead screw is rotatably connected to the middle position of the support plate, and a nut is threaded to the lead screw. A connecting rod is hinged to the sleeve, and the other end of the connecting rod is hinged to the nut.

[0006] Preferably, the sleeve has a square cross-section and is fitted with locking bolts corresponding to the outriggers.

[0007] Preferably, a base is provided below the support plate, and guide rails are provided on the left and right sides of the lead screw. The support plate and the base are fixed together by the guide rails, the nut slides up and down along the guide rails, and the lead screw is rotatably connected to the base.

[0008] Preferably, the lead screw is coaxially fixed with a knob located below the base.

[0009] Preferably, the number of the supports is three.

[0010] This utility model has the following advantages over traditional equipment: ingenious structure, simple operation, the outriggers extend and retract within the sleeve, and the length of a single outrigger can be freely adjusted, making it suitable for supporting operations on uneven soil. It is easy to adjust, has good linkage, and through the screw and nut structure, the opening and closing angles of three outriggers can be adjusted simultaneously, resulting in high work efficiency. The threaded connection has self-locking properties, high stability, and is economical and durable. Attached Figure Description

[0014] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings.

[0015] Depend on Figures 1 to 2 An auxiliary device for engineering geological surveying is provided, comprising a surveying instrument 1, a gimbal 2, and a leg assembly. The leg assembly includes a support plate 3. The gimbal 2 is mounted above the support plate 3. Multiple supports 4 are evenly hinged around the lower circumference of the support plate 3. A sleeve 5 is fixed to the other end of the support 4. A leg 6 is slidably connected inside the sleeve 5. A base 7 is hinged to the other end of the leg 6. A cone 8 is fixed to the lower end of the base 7. A protective sleeve 9 is threaded to the lower end of the base 7. The cone 8 is located inside the protective sleeve 9. A vertical lead screw 10 is rotatably connected to the middle position of the support plate 3. A nut 11 is threaded to the lead screw 10. A connecting rod 12 is hinged to the sleeve 5. The other end of the connecting rod 12 is hinged to the nut 11.

[0016] To ensure the stability of the outrigger 6 sliding within the sleeve 5 and to prevent the outrigger 6 from rotating within the sleeve 5, the sleeve 5 has a square cross-section and is equipped with locking bolts 13 corresponding to the outrigger 6.

[0017] The support plate 3 is provided with a base 14 below it, and the lead screw 10 is provided with guide rails 15 on both sides. The support plate 3 and the base 14 are fixed together by the guide rails 15. The nut 11 slides up and down along the guide rails 15, and the lead screw 10 is rotatably connected to the base 14.

[0018] To facilitate the rotation of the lead screw 10, a knob 16 located below the base 14 is coaxially fixed to the lead screw 10.

[0019] The number of brackets 4 is three.

[0020] In use, during engineering geological surveying, a suitable location is selected, and knob 16 is rotated. Knob 16 drives screw 10 to rotate, and screw 10 drives nut 11 to slide up and down along guide rail 15. Under the action of connecting rod 12, the opening angle of the three sleeves 5 is adjusted synchronously. The sleeves 5 drive the support legs 6 to adjust their opening angle synchronously, thus achieving synchronous opening of the three support legs 6. The linkage is good and the adjustment is convenient. The protective sleeve 9 is removed by rotating the thread. The protective sleeve 9 is a sleeve structure that protects the cone head 8, preventing the cone head 8 from scratching personnel or equipment during transportation. The base 7 is hinged to the support legs 6, allowing adjustment of the base 7 and the cone head. The overall swing angle of the 8-axis facilitates the insertion of the cone 8 into the geological structure, ensuring the stability of the outrigger assembly. Due to the unevenness of the geological conditions during outdoor operations, the locking bolt 13 is loosened, allowing the outrigger 6 to slide within the sleeve 5. The length of the outrigger 6 can be flexibly adjusted to suit different geological conditions for support and fixation. Then, the locking bolt 13 is tightened to fix the outrigger 6 inside the sleeve 5, ensuring good stability. The gimbal 2 and the surveying instrument 1 are then turned on to perform geological surveying. After the surveying is completed, the knob 16 is reversed, causing the lead screw 10 to drive the nut 11 to reset. The three supports 4 simultaneously move towards the lead screw 10 for easy storage. The protective sleeve 9 is then threaded onto the base 7 to protect the cone 8, ensuring safety and stability.

[0021] This embodiment does not impose any limitation on the shape, material, structure, etc. of this utility model. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of this utility model shall fall within the protection scope of this utility model.
