Abstract
The utility model relates to a direct and reverse circulation drilling machine. Motor vehicle chassis's upper end fixed distribution box and hoist engine, the rear end is fixed little, and little is articulated with big frame, and fixed unit head assembly is gone up to big frame, and direct -reversed circulation conversion equipment is fixed to the unit head assembly, and direct -reversed circulation conversion equipment's upper end communicates with each other with pump body assembly is sealed, and direct -reversed circulation conversion equipment's lower extreme communicates with each other with the hole of drilling rod is sealed. Its simple structure can realize the direct and reverse circulation drilling machine conversion fast.
Description
Technical field
This utility model belongs to rig, the rig that more particularly to a kind of energy reverse circulation is used.
Background technology
Although clean-out machine has many good qualities, but when thick sand bed is run into, easily steps on sky, it is impossible to the slip casting into wellhole
Water conservation hole wall.
The content of the invention
In order to overcome the shortcoming of prior art, this utility model to provide a kind of direct and reverse circulation drilling machine, its simple structure can be fast
Speed realizes that direct and reverse circulation drilling machine is changed.
The technical scheme in the invention for solving the technical problem is：Distribution box is fixed in the upper end of motor-vehicle chassis
And hoist engine, rear end fixes little frame, and little frame is hinged with big frame, and unit head assembly is fixed on big frame, and unit head assembly is fixed positive and negative
Cycle conversion device, the upper end of reverse circulation conversion equipment are communicated with the sealing of pump housing assembly, the lower end of reverse circulation conversion equipment
Communicate with the endoporus sealing of drilling rod.
This utility model has following advantages：1), possess whole operation functions of clean-out machine；2), need not move
Main frame, by simple dismounting, adds direct circulation device, you can realize whole operation functions of circulation drill；3) just, remove
Circulating device, you can revert to clean-out machine, realizes positive and negative rig rapid translating；4), quickly cut by reverse circulation device
Change, inject water into bottom hole portion, mud of gushing out completes deep bores operation；5) frost boiling protection hole wall operation, is realized during pile hole.
Description of the drawings
With reference to the accompanying drawings and examples this utility model is further illustrated.
Fig. 1 is this utility model schematic diagram；
Fig. 2 is enlarged drawing at the A in this utility model Fig. 1.
Specific embodiment
As shown in Figure 1, 2, distribution box 7 and hoist engine 5 are fixed in the upper end of motor-vehicle chassis 6, and little frame 9, little frame 9 are fixed in rear end
It is hinged with big frame 1, on big frame 1, fixes unit head assembly 4, unit head assembly 4 fixes reverse circulation conversion equipment 3, reverse circulation
The upper end of conversion equipment 3 is communicated with the sealing of pump housing assembly 2, and the lower end of reverse circulation conversion equipment 3 and the endoporus of drilling rod 8 seal phase
It is logical.
Described reverse circulation conversion equipment 3 includes threeway 10, lower threeway 11, suction hose 12 and water inlet pipe 13, upper three
Logical 10 and lower 11 series seal of threeway fix, the inlet seal with pump housing assembly 2 suitable for reading of upper threeway 10 is communicated, pump housing assembly
2 outlet is communicated by the side mouth of a river sealing of water inlet pipe 13 and lower threeway 11, the collector nozzle of lower threeway 11 and the endoporus of drilling rod 8
Sealing is communicated, and the side mouth of a river of upper threeway 10 is communicated with one end sealing of suction hose 12, and the other end of suction hose 12 is communicated with pond.
Water fender 14 is hinged with the inwall of the upper threeway 10 and lower 11 junction of threeway.Threeway 10 can be made with
Threeway 11 is connected or is disconnected.
During reacting cycle operation, water inlet pipe 13 and suction hose 12 are laid down, by the outlet of pump housing assembly 2, the side of upper threeway 10
The side mouth of a river sealing of the mouth of a river and lower threeway 11.Water fender 14 is opened, and water fender 14 is fixed on the side wall of upper threeway 10.Pump
Body assembly 2 is by drilling rod 17 by outside mud out well.
During direct circulation operation, put down water fender 14 and tighten, upper threeway 10 and lower threeway 11 are disconnected.Suction hose is loaded onto respectively
12 and water inlet pipe 13.During work, water enters pump housing assembly 2 from suction hose 12, is pressurizeed by pump housing assembly 2, is sequentially entered into water
Pipe 13, lower threeway 11, drilling rod 8, finally enter shaft bottom, and mud is extruded well chamber to ground.
