Hydraulic walking type percussion reverse circulation slot repairing machine

Abstract

The invention discloses a hydraulic walking type percussion reverse circulation slot repairing machine, belonging to the technical field of well drilling equipment. A chassis is arranged below a frame and connected with the frame through a revolving support, a guide frame comprises a columnar pile, guide tracks and a connecting rod, the bottom of a mast is articulated at the front of the frame, the two ends of a variable amplitude oil cylinder are respectively connected on the mast and the frame, a gooseneck boom is arranged at the top end of the mast, the guide tracks are arranged on the left side surface and right side surface of the mast, the guide frame is positioned in front of the mast and connected with the mast, the top end of the guide frame is connected with an auxiliary winch steel wire rope, the other end of the auxiliary winch steel wire rope is connected onto an auxiliary winch through a pulley on the gooseneck boom, a percussion bit is positioned in front of the guide frame and clamped on the guide tracks through guide claws, the top end of the percussion bit is connected with a main winch steel wire rope, the other end of the main winch steel wire rope is connected onto a main winch through the pulley on the gooseneck boom, and an air compressor is connected with a curved pipe at the lower part of the columnar pile through an air conveying pipe. The hydraulic walking type percussion reverse circulation slot repairing machine can flatly enlarge and excavate the edges of a channel, ensure that the bottom of the channel is through and simultaneously remove the soil and rock at the bottom of the channel during repair of the channel.

Description

technical field [0001] The invention relates to a hydraulic walking type impact reverse circulation groove repairing machine, which belongs to the technical field of drilling equipment. Background technique [0002] The Golmud area of ​​Qinghai Province in my country is extremely rich in resources. In addition to the exploitation of traditional resources such as oil and coal mines, the rich salt mine resources in Golmud also need to be exploited. Generally, salt mines are stored in brine at a depth of 40 meters underground. Therefore, if you want to mine salt mines, you must first Excavate a 40-meter-deep channel. The traditional machine for excavating the channel is an excavator. The excavator is used to excavate in stages. The drop of each layer is 8 meters. The final section of the trench is stepped. Excavator excavation footage efficiency is very low. In order to improve the efficiency of canal digging, the rotary drilling rig is used instead of the excavator, and the rot...

[0002] The Golmud area of ​​Qinghai Province in my country is extremely rich in resources. In addition to the exploitation of traditional resources such as oil and coal mines, the rich salt mine resources in Golmud also need to be exploited. Generally, salt mines are stored in brine at a depth of 40 meters underground. Therefore, if you want to mine salt mines, you must first Excavate a 40-meter-deep channel. The traditional machine for excavating the channel is an excavator. The excavator is used to excavate in stages. The drop of each layer is 8 meters. The final section of the trench is stepped. Excavator excavation footage efficiency is very low

In order to improve the efficiency of canal digging, the rotary drilling rig is used instead of the excavator, and the rotary drilling rig drills holes along the channel on the ground (such as Image 6 shown), and then re-drill a new hole in the middle of two adjacent holes, and finally form a channel. However, only a single hole can be used to dig a channel with a rotary drilling rig, and soil cannot be taken. If soil is to be taken, the reaming drill bit and Sand buckets should be used alternately, and frequent replacement of drill bits will seriously affect the construction efficiency; in addition, the force on the drill bit is not uniform during reaming, and it is easy to deviate when drilling in hard rock, resulting in the inability to penetrate the bottom of the canal and fail to meet the construction requirements
