Description
Technical field
The utility model is specifically related to a kind of long-spiral drilling machine, belongs to drilling rig technique field.
Background technology
At present, the feature that long-spiral drilling machine has in construction " environmental protection, efficient ", is therefore obtained for extensive use, particularly in present building pile foundation engineering field in all kinds of house and civilian construction.But when hard formation is constructed, the efficiency of construction of long-spiral drilling machine is low, execute cause creep into resistance large, creep into the problem working medium amount such as difficult and be difficult to ensure.Be mainly manifested in: 1. when guncreting, concrete particle easily blocks tracheae; 2. after desired depth is got in boring, guncreting is carried out to stake holes, need to promote drilling rod concrete perfusion, the too fast easily collapse hole of hoisting velocity, the too slow easily plugging even booster of hoisting velocity.Therefore the speed promoted of holing determines the quality of stake holes, also causes very large impact to workmanship and duration
Utility model content
For above-mentioned prior art Problems existing, the utility model provides a kind of long-spiral drilling machine, and when pressing filling, tracheae blocking number of times obviously reduces, and efficiency of construction significantly promotes, and also solves the problem that difficulty is crept in hard formation construction simultaneously.
To achieve these goals, a kind of long-spiral drilling machine of the present utility model, comprise drill main body and the air compressor machine that is connected with drill main body and concrete pump, described air compressor machine is connected with the interface A of slip casting mechanism by tracheae, installs one way valve at interface A place; Described concrete pump is connected with slip casting mechanism by concrete flexible pipe, and described slip casting mechanism is flexibly connected with extension bar, and described extension bar is flexibly connected with drilling rod, and described drilling rod is flexibly connected with drill bit, and drill bit arranges an air outlet; Described extension bar is by key card unit head, and described unit head can at slide on rails.
Between described slip casting mechanism and concrete flexible pipe, concrete pressure sensor is installed.
The switch being used for controlling air compressor machine startup or cutting out is installed in the driver's cabin of described drill main body.
Described slip casting mechanism and extension bar are bolted.
Described extension bar and drilling rod are by pinned connection, and described drilling rod and drill bit pass through pinned connection.
Beneficial effect: this long-spiral drilling machine passes into pressure-air to drilling rod constantly by air compressor machine in hard formation construction, pressure-air flows out from drill bit air outlet, by blowouts such as the clay on drill bit and drilling rod, rubbles, decrease and creep into resistance, shorten the pore-forming time; Install one way valve at the interface A place of slip casting mechanism, prevent the concrete particle when pressing tank from entering tracheae and result in blockage, efficiency of construction obviously promotes, and also solves construction and creeps into difficult problem.
Concrete pressure sensor is installed between slip casting mechanism and concrete flexible pipe, then when long-spiral drilling machine guncreting, concrete pressure sensor detects injection pressure in real time, the hoisting velocity of drilling rod is controlled according to injection pressure, avoid the generation of collapse hole, plugging and booster phenomenon, effectively improve efficiency of construction and workmanship.
In the driver's cabin of drill main body, install the switch being used for controlling air compressor machine startup or closing, operating personnel only just can need operate in driver's cabin, more convenient, fast.
The slip casting mechanism of this long-spiral drilling machine and extension bar with bolts, preferably adopt high strength exploitation, stress performance is good, replaceable, endurance, particularly under dynamic load(loading) effect unlikely loosen etc. advantage.
Extension bar in long-spiral drilling machine and drilling rod are by pinned connection, and drilling rod and drill bit are also by pinned connection, so both ensure that static state was fixedly connected with, and also can do relative motion with connected piece, reliable operation, convenient disassembly.

In figure: 1, air compressor machine, 2, concrete pump, 3, drill main body, 4, slip casting mechanism, 5, concrete pressure sensor, 6, concrete flexible pipe, 7, extension bar, 8, unit head, 9, drilling rod, 10, drill bit.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 1, this long-spiral drilling machine, the air compressor machine 1 comprising drill main body 3 and be connected with drill main body 3 and concrete pump 2, air compressor machine 1 is connected with the interface A of slip casting mechanism 4 by tracheae, and installs one way valve at interface A place, and concrete pump 2 is connected with slip casting mechanism 4 by concrete flexible pipe 6, slip casting mechanism 4 is flexibly connected with extension bar 7, extension bar 7 is flexibly connected with drilling rod 9, and drilling rod 9 is flexibly connected with drill bit 10, and arranges an air outlet on drill bit 10; Extension bar 7 is stuck on unit head 8 by key, and described unit head 8 can be free to slide on guide rail; Concrete pressure sensor 5 is installed between slip casting mechanism 4 and concrete flexible pipe 6.
For easy to operate, install in the driver's cabin of described drill main body 3 and be used for controlling air compressor machine 1 switch that starts or close.
The course of work: the unit head 8 of this long-spiral drilling machine drags extension bar 7 by key and rotates, and drives the rotary drilling of drilling rod 9 and drill bit 10 or get out with this.Opening installation starts and closing switch at the air compressor machine 1 of drill main body 3 driver's cabin, open air compressor machine 1, the gases at high pressure that air compressor machine 1 produces flow through slip casting mechanism 4, extension bar 7, drilling rod 9 successively, finally flow out from the air outlet of drill bit 10, by the blowout such as clay, the rubble ground on drilling rod 9 and drill bit 10, reduce and creep into resistance, improve efficiency of construction; Meanwhile, be arranged on the one way valve at the joint A place of slip casting mechanism 4, concrete particle blocking tracheae when can effectively prevent pressure from filling with;
After rig creeps into desired depth, close air compressor machine 1, open concrete pump 2, concrete flows through slip casting mechanism 4, extension bar 7, drilling rod 9 successively by concrete flexible pipe 6, finally reach drill bit 10 place, concrete pressure sensor 5 detects concrete pressure in real time, controls the hoisting velocity of drilling rod 9, complete guncreting according to injection pressure, avoid the generation of the phenomenons such as collapse hole, plugging, booster, effectively improve workmanship and efficiency of construction.
In order to convenient disassembly, reliable operation, slip casting mechanism 4 and the extension bar 7 of long-spiral drilling machine are bolted; The extension bar 7 of long-spiral drilling machine is with drilling rod 9 by pinned connection, and drilling rod 9 and drill bit 10 also pass through pinned connection.
