Abstract
Claims
1. An engineering surveying device, comprising a support plate (1), a load-bearing box (2) fixed to the bottom surface of the support plate (1), and a level main body (3) installed on the top surface of the support plate (1), characterized in that, Also includes: The first expansion unit (4) and the second expansion unit (5) are disposed on the carrier box (2); The first expansion unit (4) includes a lead screw (401), a guide rod (402), a support block (403), and an expansion box (404). The lead screw (401) is movably disposed on the inner wall of one end of the carrier box (2), and the guide rod (402) is fixedly disposed on the inner wall of the other end of the carrier box (2). There are four support blocks (403) in total, which are divided into two groups. One group of support blocks (403) is respectively matched with the two symmetrically arranged positive and negative threads on the lead screw (401). The other group of support blocks (403) is movably sleeved on the outer circumferential surface of the guide rod (402). Between every two support blocks (403) located on the same longitudinal center horizontal plane, there is an expansion box (404) that extends movably to the outside of the carrier box (2). The second expansion unit (5) includes a slide rod (501), a slider (502), an expansion strip (503), an anti-slip rubber strip (504), and a limiting bolt (505). The slide rod (501) is T-shaped and fixedly mounted on the inner wall of one end of the expansion box (404). The slider (502) is movably mounted on the outer circumferential surface of the slide rod (501). One side of the expansion strip (503) is fixedly connected to the end face of the slider (502) and extends movably to the outside of the expansion box (404). A strip-shaped groove is provided on the top surface of the expansion strip (503). The anti-slip rubber strip (504) is fixedly mounted on the strip-shaped groove. The limiting bolt (505) is threadedly connected to the top surface of one end of the expansion box (404) and extends into the strip-shaped groove.
2. The engineering surveying device of claim 1, wherein: The lead screw (401) extends movably to the outside of the bearing box (2) and a turntable (6) is fixedly installed at one end.
3. The engineering surveying device of claim 1, wherein: The slide bar (501) and the lead screw (401) are arranged parallel to each other.
4. The engineering surveying device of claim 1, wherein: The limiting bolt (505) and the slide bar (501) are arranged perpendicular to each other.
5. The engineering surveying device of claim 1, wherein: Each pair of sliders (501) are arranged symmetrically inside the expansion box (404), and the slider (502) is arranged in a one-to-one correspondence with the slider (501).
6. The engineering surveying device of claim 1, wherein: The support plate (1) has two lifting handles (7) symmetrically and movably installed on its two sides.
