Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of exploration and drilling, in particular to a drilling tool pulling device. Background Art
[0002] The twist drill is a very commonly used manual drill in water conservancy and hydropower line projects. Because it is light and easy to carry, it has great advantages in mountainous areas with inconvenient transportation and cultivated areas where land acquisition is difficult.
[0003] However, the spiral groove drill bit structure of the twist drill determines that it is easy to drill in but difficult to pull out during drilling operations; drilling only requires human rotation, and the drill bit can destroy the soil structure by drilling, but pulling out requires human power to pull out and cut the soil, and the pulling force must be greater than the shear resistance of the drilled soil. The more you drill, the greater the shear resistance of the soil, and the greater the required pulling force. The length of the twist drill bit is generally 20-30cm, but in actual drilling operations, it is often necessary to pull out the drill after drilling 2-5cm. This is mainly because the shear resistance of the soil on the drill bit makes it very difficult to pull out the twist drill, which in turn leads to extremely low drilling efficiency of the twist drill, which is only 10%-25% of the design. Therefore, it is necessary to develop a pulling device that increases the pulling force to improve the drilling efficiency of the twist drill.
[0004] Patent CN202320952116.X discloses a lightweight gear-type twist drill. Although it can facilitate the pulling out of the twist drill to a certain extent, it requires modification of the entire set of twist drill tools, that is, adding structures such as racks to the twist drill rod, so that the drill rod is no longer smooth and straight, affecting the drilling of the twist drill and reducing the drilling efficiency.

[0031] Further, it should be explained that the drill tool pulled out by the drill tool pulling out device 100 in this embodiment may be a twist drill 200. Of course, other small-sized artificial drill tools may also be pulled out according to different work requirements.
[0032] In this embodiment, if Figure 1 and Figure 3 As shown, the lifting frame 102 mainly includes a base plate and a support frame, the base plate is used to be placed flat on the ground 301, the support frame is vertically arranged on the base plate, and the pedal mechanism 101 is rotatably connected to the support frame through a first pin shaft 105; wherein, the first pin shaft 105 is horizontally arranged and perpendicular to the length direction of the base plate, so that the pedal mechanism 101 can rotate up and down.
[0033] In this embodiment, the front end of the base plate extends beyond the clamp 103, so that the length of the base plate is longer and the overall stability can be ensured; and a groove 109 is provided at the front end of the base plate, and the groove 109 is located below the clamp 103 for the drill rod of the drilling tool to pass through.
[0034] In this embodiment, an anti-slip structure 104 is also provided on the footrest to improve the anti-slip effect and facilitate the staff to apply force with their feet; as a preferred implementation, the anti-slip structure 104 can be an anti-slip pattern, or other anti-slip structures 104 can be selected according to work needs, for example, an anti-slip mat can be laid on the footrest as the anti-slip structure 104.
