Description
Technical field
The utility model relates to building machinery field, particularly relates to a kind of two embedding rock drilling machine of column high pulling torque long spire.
Background technology
As everyone knows, long-spiral drilling machine is mainly used in northern China and west area, completes creeping into-guncreting-rear slotting reinforcing cage pile in the good soil layer of soil mechanical properties.Have that speed of application is fast, mud-less pollution and the advantage such as construction costs is lower.But existing long-spiral drilling machine all adopts list or bi-motor to drive, power of motor 45-75kw, moment of torsion 3.5-8 ton rice.So long-spiral drilling machine can only creep into soil layer or the compressive strength soft rock lower than 20MPa.
At the building of China coast soft clay area, when upper soil horizon mechanical property is poor, engineering pile stake end can be embedded the hard rock 1-3 times of stake footpath that compression strength value is 60-120MPa, to improve bearing capacity and the resistant slide of stake by designer.Embed the hard rock being greater than 60MPa, cannot construct with existing long-spiral drilling machine, this type of pile foundation existing can only adopt the percussive drill that cost is high, have mud contamination, or construction cost is higher, the down-hole hammer drilling machine construction that more consumes energy.
Utility model content
The utility model provides a kind of two embedding rock drilling machine of column high pulling torque long spire, and its unit head can export large-tonnage moment of torsion, and quick, low cost completes a footpath 0.6-2 rice, the construction piercing the castinplace pile of block stone gravel layer or hard rock of the long 60-100 rice of stake.The compression strength value of hard rock described herein is 60-120MPa, mud-less pollution in construction.China's soft clay area bearing course at pile end buried depth is in the majority with 50-80m, and adopt two pillar construction can construct on earth at the drilling rod of a column, the drilling rod connecting of another column continues construction, and avoid single stand column pile machine extension bar, workman must go up to pile frame top anchor tip.
The technical solution adopted in the utility model is: a kind of two embedding rock drilling machine of column high pulling torque long spire, it is characterized in that, on walking or stride-cterpillar drive, erection chassis, chassis is established two column, two column diclinic support is adjustable fixing, chassis is also provided with undercarriage, control cabinet and 2-4 platform hoist engine; Two column tops top sheave group hangs unit head, and unit head is made up of 4 75-110 kilowatt of variable-frequency motors, frequency converter, reductor, driver pinion, driven gear wheel and hexagonal jointings; Power head device output speed is 1-60 rev/min, and output torque is 20-100 ton rice; Connect long screw drill rod under unit head, under drilling rod, connect embedding rock drill bit.Stride-cterpillar drive described herein is the long stride retaining walking, and replaced by crawler unit by short stride, purer walking action is rapider.Comparatively crawler type device, because contact area increases, pile frame construction is safer stable.
A kind of two embedding rock drilling machine of column high pulling torque long spire compared with prior art, there is obvious superiority, large-tonnage moment of torsion can be exported, drive auger stem and carbide drill in the stratum of 60-120MPa ragstone or gravel layer, very fast high-bearing capacity engineering pile of constructing out, also reduces mud-less pollution in Foundation Design cost and construction.
Accompanying drawing explanation
Fig. 1 is the utility model embodiment side elevational cross-section schematic diagram.
Fig. 2 is that the utility model embodiment faces generalized section.
Drawing illustrates: 1 top pulleys group, 2 columns, 3 unit head lifting wire ropes, 4 open frame wire rope, 5 diagonal braces, 6 undercarriages, 7 hoist engines, 8 switch boards, 9 chassis, 10 long stride oil cylinders, 11 long strides, 12 short stride oil cylinders, 13 short strides, 14 assembly pulleys, 15 embedding rock drill bits, 16 locators, 17 auger stems, 18 unit heads.
Detailed description of the invention
Below in conjunction with accompanying drawing 1, the utility model is described in further detail: the construction sequence of a kind of pair of embedding rock drilling machine of column high pulling torque long spire comprises:
1. each for the utility model rig parts are transported to job site assembling, at field boundary on the ground, first be well placed the long stride of two pieces (11) and the short stride of two pieces (13), installation chassis (9) on it, column (2) is installed on chassis (9), undercarriage (6), diagonal brace (5), hoist engine (7), switch board (8), and column (2) is erected, by top pulleys group (1) and assembly pulley (14) and hoist engine (7), by unit head (18), long screw drill rod (17) and drill bit (15) hang on column (2),
2. walked by long stride (11) and short stride (13), mobile drill is on stake position;
3. start frequency converter and 2 motors, frequency converter leaves to 50HZ, and the rotating speed of motor is 960 revs/min, through reductor, unit head (18) exports little moment of torsion height rotating speed, drives long screw drill rod (17) and drill bit (15), creeps into soil layer;
4. when drill bit (15) will enter gravel layer, turned down gradually from 50HZ by frequency converter, the rotating speed of motor also reduces gradually, and through reductor, unit head output torque increases, and drives long screw drill rod and drill bit, creeps into gravel layer;
5. when entering the hard rock of 60-120MPa, increasing and start another 2 motors and turn down frequency converter, making rotating speed be down to 2-4 rev/min, unit head moment of torsion exports and reaches 60-100 ton rice, ensures that drill bit creeps into hard rock until projected depth;
6. pumping high slump concrete enters stake holes from drilling rod center cavity by drill bit valve, pours into high slump concrete to design elevation with carrying boring to stake holes;
7. when after auger stem and carbide drill lift-off stake holes, stake machine moves next position and goes round and begins again, and continues the 3. to 5. step construction;
8. hang reinforcing cage and be inserted into setting absolute altitude from the vibration of concrete center vibrating hammer, namely complete the construction of this project long spire piles set into rock.
