Description
Technical field
The utility model relates to architectural engineering testing equipment fields, more specifically, it relates to a kind of dead load test on pile foundation
Pile pulling device.
Background technique
Simulation pile static loading test is to fill soil in the ground case of comprehensive geotechnological case, by loading device by Model Pile
It is pressed into soil, by data such as the strains of the load of collection analysis piling process and test pile pile body, analyzes the stress shape of pile body
State.After the test, it is stood in the soil of geotechnological case because pile body buries, manually force is pulled out very difficult, need to draw sandy soil around
Sky is likely to extract pile body, useless power when giving up.Although can also be extracted using simple tether, rope ridding bitt cognition rolls
It touches geotechnological case glass and generates destruction.
Utility model content
In view of the deficienciess of the prior art, the purpose of this utility model is to provide a kind of pile foundations to solve the above problems
Static test pile pulling device grips pile body from top, and uplink is pulled out, easy to operate, laborsaving.
To achieve the above object, the utility model provides following technical solution:
Dead load test on pile foundation pile pulling device, including bracket, clamping device and elevating mechanism, the bracket are erected in ground case
Two sides, which is provided with gliding groove, and the clamping device includes being suspended from plier above the ground case clamp upward to lower plier handle,
Two clamp handle tail ends are rotatablely connected nut set respectively, and nut covers spinning on the screw rod being horizontally set with, and screw rod outer end is slidably connected at bracket
In sliding slot, connecting spring I between two clamp handles, nut set outside, pocketed springs II on screw rod, elevating mechanism is drivingly connected clamping machine
Structure is run up and down.
It is the plier end face semicircular in shape of the clamp that the utility model, which is further improved technical solution, and two semi-cavities are closed
It embraces into open tubular column.Two cavity of plier holds tight pile body from two sides, and clasping is firm.
The utility model is further improved technical solution, is equipped with annular groove, nut set on the outside of the clamp handle tail end of the clamp
Inner end active card in annular groove, formed rotary connection structure.Withdrawing nut set is revolved along screw rod precession, adjusts distance between two clamp handles,
Realize the loose clip pile body of plier, nut set rotates and clamp handle, screw rod are motionless.
The utility model is further improved technical solution, is equipped with bullet in nut set inner cavity, between screw rod and clamp handle
Spring III.Gap between III retractable support clamp handle of spring and screw rod shakes clamp stabilization not.
The utility model is further improved technical solution, and the elevating mechanism is flexible on fixed top of support cross bar
Cylinder, the clamping device of the telescopic rod connection lower section of telescoping cylinder.
The utility model the utility model has the advantages that
To intermediate rotating nuts set when use, two clamp handle distances are pushed towards, then two semicircular plier firm grip pile body, spring I,
The locked entire clamping device of tensioning of spring II is stablized, and elevating mechanism traction clamping device is run up, and extracts pile body, and operation is light
It is laborsaving.
Detailed description of the invention
FIG. 1 is a schematic structural view of the utility model；
Fig. 2 is clamp schematic cross-section.
Specific embodiment
As shown in Figure 1, 2, the utility model includes bracket 1, clamping device and elevating mechanism, and the bracket 1 is erected in rock
Native 4 two sides of case, which is provided with gliding groove 11, and the clamping device includes that the plier that is suspended from above ground case is upward to lower plier handle
Clamp 21,211 end face semicircular in shape of plier, two semi-cavities fill the span of a man's arms into open tubular column, annular groove are equipped on the outside of two clamp handles, 212 tail end
213, the inner end active card of nut set 22 forms rotary connection structure in annular groove 213, and nut covers 22 outer end spinnings and is being horizontally set with
On screw rod 23,23 outer end of screw rod is slidably connected in bracket chute 11, connecting spring I 24 between two clamp handles, nut set outside,
Pocketed springs II 25 on screw rod, nut cover in inner cavity, are equipped with spring III 26 between screw rod and clamp handle, rotate the nut set of two sides
To intermediate opposite propulsion, clamp handle spacing becomes smaller, while two semicircle pliers of lower section are bonded 5 outer wall obvolvent of pile body, spring I, bullet
Integral retaining mechanism is tensioned by spring II, spring III, and elevating mechanism is the telescoping cylinder 3 on fixed top of support cross bar, and telescoping cylinder is stretched
The clamping device of contracting bar connection lower section, traction clamping device are run up, and extract pile body.
The above is only the preferred embodiment of the utility model, and the protection scope of the utility model is not limited merely to
Above-described embodiment, technical solution belonging to the idea of the present invention belong to the protection scope of the utility model.It should refer to
Out, for those skilled in the art, it is without departing from the principle of the utility model it is several improvement and
Retouching, these improvements and modifications also should be regarded as the protection scope of the utility model.
