Description

Technical Field

[0001] The invention relates to the field of geotechnical engineering investigation, and in particular to a wheel-type shallow-layer threaded drill straightening device and a use method thereof. Background Art

[0002] Shallow threaded drills can be used to determine the thickness of fill layers, the depth of hidden bays, the depth of shallow soil bearing layers, etc., and are widely used in geotechnical engineering surveys of natural foundations and poor geological conditions. The traditional drilling method for shallow threaded drills is to use two pipe wrenches to clamp the two sides of the threaded drill rod in parallel, and use manual pressure to drill. This drilling method usually requires three people to operate together, one person to straighten the threaded drill rod, and two people to press the pipe wrench to manually shake the drilling. It is also difficult to straighten automatically, which has become a major problem in the process of geotechnical engineering surveys.

[0003] The traditional method of disassembling shallow threaded drill pipes is to clamp one drill pipe with a pipe wrench and another drill pipe with another pipe wrench, and then turn the wrenches in opposite directions to achieve disassembly. This method requires two people to work together. During the disassembly process, the sliding rod can easily cause injuries to people, which not only wastes manpower but is also unsafe.

[0004] In the existing geotechnical engineering survey technology, the commonly used solution is to add a cross bar, a tripod, a leveling bubble and other devices to the drill rod of the shallow threaded drill to achieve the drilling and straightening of the threaded drill. No matter which method is used, it cannot drill quickly and straighten automatically, and it also wastes manpower. Summary of the invention

The wheel is connected to the threaded drill through the drill rod joint. The threaded drill passes through the straightening frame to straighten the threaded drill during drilling. The pipe wrench is hinged on the bottom plate of the straightening frame to disassemble and assemble the threaded drill.

[0008] As a preferred technical solution, the wheel is composed of a handle, a turntable and at least two bolts. The handle and the turntable are an integrated structure, and the turntable is fixed to the drill pipe joint by bolts.

The top of the drill rod is fixed in a drill rod joint. The soil-extracting threaded portion and the drill bit are an integrated structure, and the soil-extracting threaded portion is connected to the drill rod by threads.

[0011] As a preferred technical solution, the straightening frame includes a base, a bottom plate, a cover plate and two brackets. The bottom plate is mounted on the base. The two ends of the cover plate are fixedly connected to the two ends of the cover plate below through a bracket respectively. There are straightening openings arranged opposite to each other in the middle of the bottom plate and the cover plate, and the threaded drill passes through the two straightening openings.

[0012] As an optimal technical solution, the pipe wrench includes a handle, a nut and a front chuck. A hinge bolt is provided on the base plate. The tail of the handle is hinged to the base plate through the hinge bolt. The front chuck is installed on the head of the handle. The clamping width of the front chuck is adjusted by turning the nut.

[0013] As a preferred technical solution, a method for using a wheel-type shallow threaded drill straightening device comprises the following steps:

[0014] Step 1: Pass the threaded drill through the two straightening holes on the straightening frame.

[0015] Step 2: Rotate the wheel to drive the threaded drill to drill downward and take soil;

[0016] Step 3. When the drill bit needs to be replaced, hinge the pipe wrench to the bottom plate in the straightening frame, adjust the front chuck of the pipe wrench to clamp the lower part of the threaded drill, rotate the wheel in reverse, and remove the soil-taking threaded part and the drill bit.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] The wheel-type shallow threaded drill straightening device and the use method of the present invention realize automatic straightening of the threaded drill during drilling by arranging two straightening ports on the straightening frame, and realize quick disassembly of the threaded drill by hingedly connecting a pipe wrench to the bottom plate of the straightening frame.
