Abstract
The utility model relates to a device enabling to realize consecutive mechanical cleaning of slime adhered between blades of a helix drilling rod during helix forming, in particular to a helix forming mechanical scraper, which comprises a scraper housing (1), a scraping cutter assembly (2), a sliding slip (3), a drive head (4), a middle protective barrel (5), a column (60, a column slide-way (7), a helix drilling road (8) and a bottom protective barrel (9). When the scraping cutter (2-1) of the scraping cutter assembly (2) is let in and positioned between two blades of the helix drilling road (8) mechanically or manually, the drive head (4) is started and the helix drilling road (8) is revolved; then the scraping cutter (2-1) can achieve consecutive automatic slime cleaning. After cleaning being finished, the scraping cutter (2-1) of the scraping cutter assembly (2) withdraws between the two blades. The utility model solves the technologic difficulty of consecutive mechanical slime cleaning in helix forming which has been confusing the engineering industry for a long time.
Description
Technical field:
The utility model relates to a kind of in the foundation pile construction of civil engineering, the device of clay between its drilling rod and the bit blades is removed in auger boring, be specifically related to a kind of motor-driven scraper, belong to International Classification of Patents E21B10/00 " drill bit " and B08B " scavenge unit " technical field.
Background technology:
In the foundation pile construction of civil engineering, auger boring is one of important hole forming method of in situ pile, but, in viscous soil horizon, be bonded between the auger stem blade owing to clay during auger boring, blocked the native passage of returning of drill bit, drill bit is drilling depth no longer, have only the drill bit of proposition and drilling rod this moment, go out the clay between drilling rod and the bit blades clearly, again bore down and could recover normal drilling depth, at present clear soil relies on manually fully, and artificial clear native recruitment is many, physical labor intensity is very big, work efficiency is extremely low, and owing to the clear soil time is long, often cause undergauge even cause the hole of collapsing, not only influence the construction party economic benefit but also influence pile quality.
Summary of the invention:
The purpose of this utility model provides a kind ofly in the spiral pore-forming, carries out device---the motor-driven scraper of spiral pore-forming of the clear soil of motor-driven continuous high-efficient to sticking to foundry loam between the auger stem blade.
The purpose of this utility model is achieved through the following technical solutions.
The motor-driven scraper of a kind of spiral pore-forming is that the motor-driven scraper of spiral pore-forming is made up of scraper frame, the native cutter assembly of shovel and sliding shoes by the motor-driven scraper of installation spiral pore-forming on the column slideway of auger machine; Make the shovel soil cutter of the native cutter assembly of shovel push, finish between geotechnological clearly preface retreats for auger stem two blades with flexible or level to swing, wander to change in conjunction with auger stem and realize clear native function automatically.Concrete scheme is as follows:
Shoveling native cutter assembly 2 is installed on the scraper frame 1 that can slide up and down along column slideway 7.
The middle casing 5 of spiral drilling machine also can be used as scraper frame 1 and uses, promptly also the native cutter assembly 2 of shovel can be installed on the middle casing 5
The shovel soil cutter (2-1) that shovels native cutter assembly 2 radially stretches into and is positioned temporarily facing space between two helical blades (8-1) up and down mutually, realizing shovel soil of auger stem 8 with motor-driven or manual mode along auger stem 8, shovel native cutter (2-1) also can be motor-driven or manual mode withdraw from the space between two blades.
Shoveling the linkage that native cutter assembly 2 swings with horizontal direction is installed on the scraper frame 1, shoveling native cutter (2-1) is that folding mode that center, along continuous straight runs swing is positioned facing space between two helical blades (8-1) up and down mutually, realizing shovel soil of auger stem 8 temporarily with hinge axis 1-2, shovel native cutter (2-1) but also backswing return from the space between two blades.
Shovel the middle part that native cutter assembly 2 can be installed in scraper frame 1 or middle casing 5 and also can be installed in upper surface or lower surface.
The utility model has solved the clear native technical barrier of the auger boring of long-term puzzlement engineering circle; Make at spiral to become in the hole operation, can implement motor-driven continuous high-efficient soil clearly the foundry loam that sticks between the auger stem blade.The utility model and traditional artificial clear soil phase ratio alleviate labor strength, work efficiency improves more than 10 times significantly, and can guarantee the construction works quality, reduce engineering cost, so have tangible economic benefit and social benefit.
