Abstract
The utility model relates to a novel percussion drilling tool which belongs to engineering drillers. The purpose of the utility model is to solve the problem of low deslagging efficiency, to improve percussive drilling efficiency and to lower the manufacturing cost of percussive drilling equipment. The utility model is characterized in that in a percussion drilling tool assembled on the front part of a driller, a percussion drill bit is connected with a cable wire; a deslagging high-strength rubber hose is connected to a percussion drill bit 7. The utility model has the advantages that drill rod-free single cable wire backcycling percussion is much more effectively realized, and construction is convenient to carry out under the condition of one pump and multiple machines; pore-forming percussion efficiency is improved; the structure of the utility model is simple, materials and energies are saved; after being tried out, the effect of the utility model is favorable.
Description
The utility model relates to engineering driller, refers in particular to a kind of novel churn drilling tools.
In background technology, the Churn drill of engineering driller has two kinds.A kind of is to grab drill bit and jump bit towards grabbing dashing in the rig; A kind of is the percussion drilling of preparing on the remodeling engineering machine.Its weak point is to liquidate and grab rig: 1. in the construction, use earlier the jump bit fractured rock, grab the rock that the drill bit extracting is broken with dashing then, frequently change drilling tool, non-cutting time is long, inefficiency; 2. in the impact grinding process, with the particle of catalase to diameter less (being generally less than 5 millimeters), by the direct circulation deslagging, the mud preparation requires high, and deslagging efficient is low.Because can not continuous discharging slag, in shattering process repeatedly, form the sand grains layer in working face, the existence of sand grains layer works to absorb impact energy, reduces impact grinding efficient, and energy consumption is big.To the percussion drilling of preparing on the remodeling engineering driller, 1. adopt jump bit and the supporting use of reverse circulation drilling bar in the construction, duplex type promotes jump bit; 2. to adopt special-purpose impact elevator equipment; 3. in creeping into, want frequent adjunction reverse circulation drilling bar, also can not work continuously, influence the raising of efficiency of construction.4. a work drilling rod is joined a deslagging pump, the function surplus, and energy consumption is big.
The purpose of this utility model is the defective that overcomes above-mentioned construction equipment and method existence, develops a kind of novel churn drilling tools, solves the problem of poor efficiency deslagging effectively, equipment manufacturing cost is low, and is in light weight, easy construction, realize that the anti-circulation impact of no drilling rod list rope creeps into, work continuously, improve target efficiency.
Technical solution of the present utility model is as follows:
Impact elevator (dash grab rig and other engineering driller elevator all can) churn drilling tools 2 of traction, comprise connecting wire rope 5 on the drill hammer 7.Be characterized in: 1. connect high strength deslagging flexible pipe 6 on the drill hammer 7, to realize the anti-continuous discharging slag that circulates; 2. deslagging flexible pipe 6 is synchronized with the movement in the construction operation process with drill hammer 7.
Technical solution of the present utility model also comprises:
In high strength deslagging flexible pipe 6, be connected with holding ring 4 with tube connector 3 between the flexible pipe 6.Be characterized in: 1. hose length can once be provided with according to the construction needs; 2. flexible pipe is along wire rope rising and fixing; 3. the flexible pipe of many churn drilling toolss can be implemented anti-circulation deslagging with a deslagging pump.
Description of drawings of the present utility model is as follows:
Fig. 1 is the overall structure schematic diagram.
Fig. 2 is the churn drilling tools structural representation.
Number in the figure is described as follows:
1-engineering driller, 2-churn drilling tools, 3-tube connector, 4-holding ring, 5-wire rope, 6-high strength deslagging flexible pipe, 7-drill bit.
Embodiment of the present utility model is described as follows:
Referring to Fig. 1, engineering driller 1 is positioned on the pebble layer, and its Foundation Design is constructed, and the churn drilling tools 2 of engineering driller 1 front portion is under the pulling of wire rope 5, lift by crane and freely fall and construct, referring to Fig. 2, in the drilling tool 2, the flexible pipe 6 that connects inverse circulation pump is connected with churn drilling tools 7, drilling tool 7 is by wire rope 5 tractions, flexible pipe 6 is fixed along wire rope, and in the construction, flexible pipe 6 is synchronized with the movement with drilling tool 2.Be connected with holding ring 4 with tube connector 3 between the flexible pipe 6.Whole operating principle is: utilize anti-circulation impact, along with construction needs, connect prolongation with tube connector 3 and holding ring 4 between the high-intensity flexible pipe 6.
Advantage of the present utility model and effect are as follows:
1, owing to adopt technical solutions of the utility model, effectively realizes the anti-circulation impact of single rope, in time have The deslagging of effect in time exposes the new section after the impact grinding, is convenient to follow-up fragmentation, thereby effectively improves Construction effect.
2, adopt technical solutions of the utility model, realize substituting counter circulation drill rod with flexible pipe, work continuously, Saved drilling rod and changed the time, easy construction further improves work efficiency.
3, the enforcement of new technique scheme, construction equipment is simplified greatly, and operating expenses has bigger reduction. Effective work capacity of equipment increases substantially, functions of the equipments cost ratio height.
4, realize many bench drills machine with a deslagging pump, mud pit is concentrated to be used, and has made things convenient for the pipe of job site Reason. Because weight of equipment is light, also the convenient construction tissue.
Claims (3)
