Further, a limiting clamping block is arranged on the side wall of the rack, and a clamping column is arranged on the top of the disc.
The utility model has the beneficial effects that: the rack and the cross rod are driven to shrink towards the center direction of the disc through gear rotation, so that the clamping arms can gradually clamp soil sample columns, extraction of soil sample columns with different diameters is achieved, time and labor are saved, the soil sample columns are prevented from being left in drilling holes, the times of re-drilling and sampling are reduced, and the overall construction progress of road bridge construction is guaranteed.
Description of the drawings:
FIG. 1 is a schematic diagram of the overall structure of the present utility model;
FIG. 2 is a schematic cross-sectional view of section A-A of FIG. 1;
in the figure, 1 disc, 2 gear, 3 bull stick, 4 racks, 5 horizontal pole, 6 fixed plates, 7 clamp arm, 8 screw rods, 9 ratchet, 10 pawl, 11 draw handle, 12 spacing fixture block, 13 draw-in posts.
The specific embodiment is as follows:
for a clearer understanding of technical features, objects, and effects of the present utility model, a specific embodiment of the present utility model will be described with reference to the accompanying drawings:
referring to fig. 1 to 2, a road and bridge detection sample extraction device includes a disc 1, a gear 2 is rotatably connected to the top of the disc 1, a rotating rod 3 is coaxially and vertically installed at the top of the gear 2, racks 4 are meshed with two sides of the gear 2, a cross rod 5 is installed at the outer end of each rack 4, a fixing plate 6 is installed on the disc 1, a through hole is formed in each fixing plate 6, the cross rod 5 slides in the through hole, a clamping arm 7 is vertically and downwardly installed at the outer end of each cross rod 5, a screw hole is vertically and downwardly formed at the outer end of each cross rod 5, a screw rod 8 is screwed in the screw hole, the bottom end of each screw rod 8 is fixedly connected with each clamping arm 7, each clamping arm 7 is in a half-arc shape, and anti-skid bumps are installed at the inner sides of the corresponding clamping arms 7.
Specifically, the rack 4 drives the cross rod 5 to move to shrink towards the center direction of the disc 1 by rotating the gear 2, the clamping arms 7 gradually tighten the side wall of the soil sample column, and at the moment, the extraction handles 11 are gripped by two hands to pull out the soil sample column, so that time and labor are saved, the punching quantity is reduced, and the detection construction progress is improved.
In the actual use, firstly rotate bull stick 3 according to the difference of the soil sample post diameter that draws for gear 2 rotates and drives horizontal pole 5 that rack 4 is connected and take place to remove, when clamp arm 7 is close to the gap between drilling and the soil sample post gradually, stretches into the gap with clamp arm 7, then rotates gear 2 again and makes clamp arm 7 press from both sides the lateral wall of soil sample post tightly, pulls out the soil sample post at last.
