Description
Technical field
The utility model relates to civil engineering technique with the apparatus, particularly relates to the technology of the swollen footpath of a kind of endoporus formula dart.
Background technology
In pile foundation construction, its drilling construction has crept into by rigidly connected drilling rod, bit.In drilling and forming hole construction, due to impacts such as geological conditions sudden change, depth of pore forming, drilling technical parameter variation, drilling tool mechanical strengths, the situation of drilling string broken off in stake hole is difficult to avoid.
Because the aperture of boring is less, and the degree of depth of boring is larger, in hole, also mix and have mud, clod etc., it is very large that the disconnected drilling tool dropping in a hole is salvaged difficulty, and the fall fracture of drilling tool of breaking is mostly irregular, further increased salvaging difficulty, had a strong impact on the pile foundation construction cycle, processing cost is also higher.
Utility model content
For the defect existing in above-mentioned prior art, technical problem to be solved in the utility model is to provide a kind of swollen footpath of the endoporus formula dart that can salvage quickly and easily the drilling tool in boring that drops.
In order to solve the problems of the technologies described above, the swollen footpath of a kind of endoporus provided by the utility model formula dart, is characterized in that: comprise guide rod, connecting rod;
Dock with guide rod upper end the lower end of described connecting rod, and the upper end of connecting rod is equipped with flange socket;
The lower end of described guide rod is tapered, the side face of guide rod offers at least three chutes, each chute is laid around the central axis axial symmetry interval of guide rod, described chute is linear straight trough, the radial section of chute is the T shape of mouthful narrow bottom width, each chute all tilts towards the central axial direction of guide rod in the axial direction from bottom to top, is equipped with a slide block in each chute, and the lower end of each chute is all fixed with the block gliding for block resistance slide block;
The outer face of described slide block is the cambered surface of taper, the inner of slide block is T-shaped, on slide block, be fixed with caudal peduncle, the inner of each slide block embeds respectively in each chute with gap fiting mode, the outer end of each slide block extends respectively each chute outside, is all equipped with the spring for ordering about this slide block down sliding on the caudal peduncle of each slide block.
Further, on the outer face of described slide block, be formed with the multiple resistance of the increasing for increasing frictional force grooves.
The swollen footpath of the endoporus formula dart that the utility model provides, utilizes the disconnected endoporus that drops on the drilling tool in boring of insertion that the tapered lower end of guide rod can be promptly and accurately, utilizes coordinating of slide block and spring, can salvage quickly and easily the drilling tool dropping in holing.

Detailed description of the invention
Below in conjunction with brief description of the drawings, embodiment of the present utility model is described in further detail, but the present embodiment is not limited to the utility model, every employing analog structure of the present utility model and similar variation thereof, all should list protection domain of the present utility model in.
As Figure 1-Figure 4, the swollen footpath of a kind of endoporus formula dart that the utility model embodiment provides, is characterized in that: comprise guide rod 1, connecting rod 5;
Dock with guide rod 1 upper end the lower end of described connecting rod 5, and the upper end of connecting rod 5 is equipped with flange socket 6;
The lower end of described guide rod 1 is tapered, the side face of guide rod 1 offers at least three chutes 7, each chute 7 is laid around the central axis axial symmetry interval of guide rod 1, described chute 7 is linear straight trough, the radial section of chute 7 is the T shape of mouthful narrow bottom width, each chute 7 all tilts towards the central axial direction of guide rod 1 in the axial direction from bottom to top, is equipped with a slide block 3 in each chute 7, and the lower end of each chute 7 is all fixed with the block 4 gliding for block resistance slide block 3;
The cambered surface that the outer face 34 of described slide block 3 is taper, the inner 31 of slide block is T-shaped, on slide block, be fixed with caudal peduncle 33, the inner 31 of each slide block embeds respectively in each chute 7 with gap fiting mode, the outer end of each slide block extends respectively each chute outside, is all equipped with the spring 2 for ordering about this slide block down sliding on the caudal peduncle 33 of each slide block.
In the utility model embodiment, on the outer face 34 of described slide block, be formed with the multiple resistance of the increasing for increasing frictional force grooves 32.
The using method of the utility model embodiment is as follows:
While needing to salvage the disconnected drilling tool dropping in boring, guide rod is stretched in boring, the tapered lower end of guide rod can be promptly and accurately the disconnected endoporus that drops on the drilling tool in boring of insertion, then apply downforce by the flange socket of connecting rod upper end to guide rod, guide rod is moved down, each slide block of drilling tool endoporus ejection immediately, make each slide block along the relative guide rod upward sliding of chute, because chute tilts from bottom to top towards the central axial direction of guide rod in the axial direction, slide block can be towards the center position retraction of guide rod in sliding process, guide rod moves down after certain distance, flange socket by connecting rod upper end promotes guide rod, now each slide block is under the elastic force effect of spring and the frictional force effect of slide block outer face and drilling tool endoporus hole wall, outwards drilling tool endoporus is blocked in swelling, now by the flange socket of connecting rod upper end, guide rod pull-out is holed, drilling tool can be taken out smoothly, whole salvaging process is convenient, fast, to pile foundation drilling construction quality, duration ensures, cost control all has positive meaning.
