Description
Technical Field
The utility model belongs to the technical field of the technique of digging the rig soon and specifically relates to a be used for clearing up auxiliary device who digs the last barrel drill of rig soon.
Background
The existing rotary drilling rig is a comprehensive drilling rig and is suitable for a construction process of hole forming operation in building foundation engineering. The drilling machine is widely used for foundation construction projects such as municipal construction, highway bridges and high-rise buildings, is matched with different drilling tools, and is suitable for hole forming operation of dry (short spiral) or wet (barrel drilling) and rock strata (core drilling). The drill bit form of the rotary drilling rig is preferably a cylindrical drill when the rotary drilling rig drills in the viscous soil layer.
The Chinese utility model with the bulletin number of CN203978270U and publication number of 20141203 discloses a rotary drilling rig adopting air-charging pressure control, which comprises a drill bit of the rotary drilling rig, an air-charging pressure device, a pressure gauge, an air duct, a duct connecting joint and a movable plug; the air charging pressure device is installed on the rotary drilling rig, a control valve is installed at the outlet of the air charging pressure device, the air charging pressure device is communicated with an air duct by opening the control valve, the air duct is directly communicated to a movable plug at the bottom of a drill bit of the rotary drilling rig through a pressure gauge and a duct connecting joint, the pressure gauge is arranged on the air duct and used for displaying the air pressure value of the space at the lower part of the drill bit, the movable plug is installed at the bottom of the drill bit of the rotary drilling rig and at the tail end of the air duct, the duct connecting joint is arranged at the connecting part of the upper part of the drill bit of the rotary drilling rig and the air duct, and the duct connecting joint can simultaneously separate the air ducts connected with the upper end. When the negative pressure is high, the gas pushes the movable plug away through the vent pipe and enters the bottom of the drill bit, and the drill bit of the rotary drilling rig adopts a barrel drill. The flushing pressure device is opened when the drill bit is lifted, and the control valve is opened before the flushing pressure device is opened.

Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
As shown in FIG. 1, for the utility model discloses an auxiliary device for clearing up rotary drilling rig upper barrel bores, including clean subassembly 200, clean subassembly 200 is used for clearing up the inner wall of barrel bores 100.
As shown in fig. 2, the cleaning assembly 200 (see fig. 1) includes a rectangular base 210, and a pole 220 is vertically disposed on the base 210. The supporting rod 220 comprises a first supporting rod 221 and a second supporting rod 222, the second supporting rod 222 is in threaded connection with the base 210, the first supporting rod 221 is rotatably connected with the second supporting rod 222, the first supporting rod 221 is in threaded connection with an installation block 230, a scraper 240 is welded on the installation block 230, and the scraper 240 is abutted to the inner wall of the barrel drill 100. After the cylinder drill 100 discharges soil in the hole to a place outside the hole, the cylinder drill 100 is placed above the scraper 240, and then the cylinder drill 100 is driven to descend, so that the scraper 240 automatically scrapes the inner wall of the cylinder drill 100. When the rotary drilling rig finishes working, the scraper 240 also finishes cleaning the inner wall of the cylindrical drill 100, and then the scraper 240 and the second support rod 222 are rotated, so that the scraper 240 and the second support rod 222 are detached, and therefore workers can carry the scraper and replace the damaged scraper 240 conveniently.
In order to enhance the cleaning effect of the scraper 240 on the inner wall of the barrel drill 100, one end of the scraper 240 abutting against the inner wall of the barrel drill 100 is provided in an inclined shape, and the end of the scraper 240 abutting against the barrel drill 100 is higher than the end thereof not abutting against the inner wall of the barrel drill 100.
After the scraper 240 has finished cleaning the inner wall of the barrel drill 100, the first lever 221220 is rotated to rotate the scraper 240 so that the clods on the scraper 240 are disengaged from the scraper 240. In order to prevent the scraper 240 from rotating during operation, a horizontal first bolt 250 is screwed to the second support rod 222, and a nut 260 is screwed to an end of the first bolt 250 that extends through the first support rod 221. When the scraper 240 is working normally, the first bolt 250 passes through the first support rod 221 and the second support rod 222, the nut 260 is screwed on the first bolt 250, so that the first support rod 221 is locked, when the mud cake on the scraper 240 is disengaged, the nut 260 is unscrewed, and then the first bolt 250 is rotated, so that the first bolt 250 is disengaged from the first support rod 221, so that the first support rod 221 can be rotated on the second support rod 222.
In order to facilitate the carrying of the working personnel and save labor, and make full use of space resources, a first circular placing groove 300 is formed at one end of the upper surface of the base 210, and the scraper 240 is placed in the first placing groove 300. A rectangular second placing groove 330 is formed along the length of the base 210, and the supporting rod 220 is placed in the second placing groove 330.
As shown in fig. 1 and 2, in order to prevent the scrapers 240 and the supporting rods 220 from being separated from the first placing grooves 300 and the second placing grooves 330 during the transportation process; in order to prevent the clods from entering the first and second storage grooves 300 and 330 when the scrapers 240 are operated, a first circular protection cover 310 is hinged to one end of the first storage groove 300, and a second rectangular protection cover 340 is hinged to one end of the second storage groove 330, so that the first and second protection covers 310 and 340 completely cover the first and second storage grooves 300 and 330. A second bolt 320 is connected to one end of the first shield 310 far away from the hinge in a threaded manner, a third bolt 350 is connected to one end of the second shield 340 far away from the hinge in a threaded manner, and both the second bolt 320 and the third bolt 350 are connected to the base 210 in a threaded manner, so that the first shield 310 and the second shield 340 are locked.
The specific working process of this embodiment: after the barrel drill 100 shifts the soil in the hole to the place outside the hole, the barrel drill 100 is moved to the position right above the scraper 240, and then the barrel drill 100 is driven to descend, so that the scraper 240 automatically cleans the inner wall of the barrel drill 100, thereby ensuring that the barrel drill 100 has enough space therein and improving the hole forming efficiency. After cleaning, the nut 260 is unscrewed, the first bolt 250 is then turned so that the first bolt 250 is disengaged from the first leg 221, and then the first leg 221 is turned so that the clod is disengaged from the scraper 240.
