Abstract

The invention relates to the field of drilling machines, in particular to a drill bit fishing device for self rescue in collapse. According to the drill bit fishing device for self rescue in collapse, manual fishing in water is avoided, existing fishing equipment is improved, the collapse risk in the fishing process is reduced, and self rescue can be achieved even if collapse occurs. The invention discloses a collapse self-rescue drill bit fishing device. The collapse self-rescue drill bit fishing device comprises a drill rod, four collapse self-rescue devices are fixedly installed on the outer side of the drill rod at equal angles, each collapse self-rescue device comprises a fishing box body which prevents a drill bit from being clamped underground during collapse through an inclined face, and a clamping device is arranged in each fishing box body. The clamping devices comprise bottom electric push rods used for wrapping the drill bit, two clamping mechanisms which are symmetrical up and down are arranged on the upper sides of the bottom electric push rods, and the clamping mechanisms can rotate and extend.

Description

technical field [0001] The invention relates to the field of drilling machines, in particular to a drill bit salvage device for self-rescue after collapse. Background technique [0002] When piling on the construction site, the drill bit may fall off or break. If the drill bit is not salvaged, the entire drill pile cannot be used. The position of the drill pile is determined by calculation. Once the position is changed, more drill piles need to be added, and a The cost of the drill bit and the cost of piling are very high, and it is impossible to continue drilling without salvage. [0003] Most of the existing salvage methods are salvaged by people, which is dangerous, and some are salvaged by drill bits. Most of these devices are claw-shaped. When the claws are stretched, they will touch the hole wall, which is easy to cause collapse and is more difficult Before salvage, it is necessary to determine the specific position of the drill bit. Contents of the invention [00...
