Description
Technical field
The utility model relates to a kind of counterforce device, specifically relates to a kind of counterforce device of the static sounding on hard abundant pavement of road.
Background technology
The counterforce device of current static sounding is mainly applicable to hard thinner road surface, while settling on hard abundant road surface, wastes time and energy, and especially on more abundant road surface, settles inconvenience, has increased use difficulty.For this reason, the utility model proposes a kind of counterforce device that counter-force is provided quickly and easily, is applicable to the static sounding on more abundant road surface.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, proposes a kind of counterforce device that can fast and easy provides counter-force, is applicable to the static sounding on more abundant road surface.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is as follows:
A kind of counterforce device of static sounding, described device comprises nut, sleeve, hinge, expansion pawl, screw rod and sloped footing, described screw rod is fixed on sloped footing top, described screw rod is fixed on sloped footing top, and described screw rod upper outside is provided with sleeve, and described screw rod is connected by nut with sleeve, described expansion pawl is positioned at sloped footing upper outside, inner side, expansion pawl lower end is with tapering, and described sleeve lower end is provided with hinge, and described hinge is connected with expansion pawl upper end.
Described screw rod and sloped footing adopt welding or screw thread to fix.
Described hinge is welded on sleeve lower end, and hinge outside is concave shape.
Described expansion pawl end is convex shape, and quantity is 2-6 and symmetrical.
Described expansion pawl, quantity are 4 and symmetrical.
Described spiro rod length is 0.8-1.2m.
Described spiro rod length is 1m.
The beneficial effects of the utility model:
(1) on hard abundant pavement of road during static sounding, the utility model is put into the road pit and hole of holding successfully in advance, by tightening nuts, just can provide static sounding required counter-force, convenient to use, and can on hard and thicker road surface, provide counter-force completely;
(2) can on any hard abundant road surface, not need dig on a wide area just can provide required counter-force, can greatly save expense and the maintenance and repair cost of dig on a wide area, again can rapid repairing road surface, reduce as much as possible the road safety hidden danger of being brought by road surface dig on a wide area, and can meet the requirement of civilized construction.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is top view of the present utility model;
Fig. 3 is use view of the present utility model;
In figure: nut 1, sleeve 2, hinge 3, expansion pawl 4, screw rod 5, sloped footing 6.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
In the drawings, the counterforce device of a kind of static sounding of the present utility model is mainly comprised of nut 1, sleeve 2, hinge 3, expansion pawl 4, screw rod 5 and sloped footing 6.
Described screw rod 5 adopts and is weldingly fixed on sloped footing 6 tops, described screw rod 5 length are 1m, described screw rod 5 upper outside are provided with sleeve 2, described screw rod 5 is connected by nut 1 with sleeve 2, described sleeve 2 moves axially along screw rod 5, described expansion pawl 4 is positioned at sloped footing 6 upper outside, quantity is 4 and symmetrical, expansion pawl 4 inner sides, lower end are with tapering, expansion pawl 4 ends are convex shape, described sleeve 2 lower ends are welded with hinge 3, and described hinge 3 outsides are concave shape, and the concave shape in hinge 3 outsides is connected with the convex shape of expansion pawl 4 ends.
During use, device of the present utility model is put under original state to the road pit and hole of holding successfully in advance, after being packed into screw rod 5, steel plate lies in road surface, then tightening nuts 1, screw rod 5 drives sloped footing 6 to move up, sleeve 2 is done axially to move in opposite directions along screw rod 5 with screw rod 5, thereby the sloped footing 6 of screw rod 5 bottoms and the expansion pawl 4 of sleeve 2 bottoms are moved in opposite directions, expansion pawl 4 is expanded outwardly by the extruding of sloped footing 6, lateral surface at expansion pawl 4 forms very large normal pressure, thereby produce very large frictional force with the hole wall of pavement of road hole, it is the required counter-force of static sounding.
