Description
Technical field
The utility model relates to a kind of old stake plucking device, belongs to field of engineering technology.
Background technology
Urban construction at present is very fast, need to be to originally removing with regard to building construction, and old pile foundation is pulled out, therefore the longer larger stake of constructing, need to pull out existing pile foundation, and guarantee the safety of surrounding environment, reduce the disturbance to the soil body, just need special device to realize this purpose; But present equipment has greater environmental impacts, easily causes the soil body of old stake periphery loosening and larger to the destruction of old stake in demolishing process.
Summary of the invention
The utility model has greater environmental impacts, easily causes for present equipment the problem that the peripheral soil body of old stake is loosening, destroy old stake in demolishing process, proposed a kind of protection of the environment and reduced soil disturbance, old stake is damaged less old stake plucking device.
Old stake plucking device described in the utility model, comprise pile press, with the extractor of fixture, it is characterized in that: also comprise hollow cylinder, the top of described hollow cylinder arranges installation gap, and described hollow cylinder is connected with described pile press by described installation gap.
On the sidewall of described hollow cylinder, circular hole is set.
Described hollow cylinder axially arranges equidistant circular hole along sidewall.
The top symmetry of described hollow cylinder two installation gaps are set.
Described installation gap is L-type.
During use, first cannulated sleeve is socketed in the old stake that to extract outside, optionally use pile press to press the upper end of hollow cylinder, make hollow cylinder insert in the old stake soil body on every side, then pile press and hollow cylinder are broken away from, the fixture on extractor is clipped in the upper end of old stake and screws, then extractor clockwise or be rotated counterclockwise, thereby drive old stake clockwise or be rotated counterclockwise, make the soil body around old stake be plastic state, extract old stake.
The beneficial effects of the utility model are: construction is simple, and manufacturing installation is simple, and is easy to use, reusable, and good endurance is safe.

Fig. 1 is the structure chart of pile press of the present utility model.
Fig. 2 is the structure chart of extractor of the present utility model.
Fig. 3 is the structure chart of hollow cylinder of the present utility model.
Fig. 4 is the structure chart of fixture of the present utility model.
The specific embodiment
Further illustrate the utility model below in conjunction with accompanying drawing
With reference to accompanying drawing:
Old stake plucking device described in the utility model, comprise pile press 1, with the extractor 2 of fixture 21, also comprise hollow cylinder 3, the top of described hollow cylinder 3 arranges installation gap 31, and described hollow cylinder 3 is connected with described pile press 1 by described installation gap 31.
Described hollow cylinder 3 axially arranges equidistant circular hole 32 along sidewall.
The top symmetry of described hollow cylinder 3 two installation gaps 31 are set.
Described installation gap 31 is L-type.
During use, first cannulated sleeve 3 is socketed in the old stake that to extract outside, optionally use pile press 1 to press the upper end of hollow cylinder 3, make hollow cylinder 3 insert in the old stake soil body on every side, then pile press 1 and hollow cylinder 3 are broken away from, the fixture 21 on extractor 2 is clipped in the upper end of old stake and screws, then extractor 2 clockwise or be rotated counterclockwise, thereby drive old stake clockwise or be rotated counterclockwise, make the soil body around old stake be plastic state, extract old stake.
The described content of this manual embodiment is only enumerating the way of realization of utility model design; protection domain of the present utility model should not be regarded as only limiting to the concrete form that embodiment states, protection domain of the present utility model also reaches the equivalent technologies means that design can be expected according to the utility model in those skilled in the art.
