Rotary drilling rig develops well at home in recent years, in the middle of engineering construction, the use of rotary drilling rig is more and more frequent, now widely used rotary drilling rig product is reassembling type, need mast or other critical pieces to split when moving and transport to come, then assemble again in new building site, waste time and energy, affect operating efficiency and programming.
Along with the continuous maturation of rotary drilling rig technology, domestic market requires more and more higher to the compliance of the various operating modes of rotary drilling rig, also the scope of application of rotary drilling rig is extended, not only in the construction of the major works such as railway construction, bridge construction, use rotary drilling rig, even be applied under low clearance environment in building construction, workshop building tunnel etc., because existing rotary drilling rig build is huge, be a very large obstacle therefore rotary drilling rig being constructed under low clearance environment.
Summary of the invention
It is simple that the purpose of this utility model is to provide a kind of structure, and convenient transportation, need not disassemble on a large scale, operates easier rotary drilling rig.
In order to achieve the above object, the technical solution of the utility model there is provided a kind of all hydraulic caterpillar mast height and balance weight stepless regulates back type rotary drilling rig, comprise assembly of getting off, assembly of getting on the bus is connected with assembly of getting off by revolving support, jib lubbing mechanism pinned connection is got on the bus assembly, mainmast pinned connection jib lubbing mechanism, guide rail is provided with at the front end face of mainmast, unit head hangs on this guide rail, drilling rod is hung with in mainmast front, drilling rod is through unit head, it is characterized in that: rear counterweight assembly is connected to the rear of assembly of getting on the bus by infinitely variable horizontal extension mechanism, the vertical telescoping mechanism of infinitely variable is provided with in mainmast, the bottom of secondary mast is connected with this vertical telescoping mechanism, catead is provided with at its top, after catead walked around by the wire rope of drawing below catead, drilling rod is hung on mainmast front.
Preferably, described mainmast cavity structure, described vertical telescoping mechanism is located in the cavity of mainmast.
Preferably, described catead is connected to the top of described secondary mast by bearing pin and bolt.
The utility model by mast height can the distance at step-less adjustment and rear counterweight assembly distance complete machine center can step-less adjustment, make rotary drilling rig can keep balance under different workloads, meet more construction operating modes, eliminate more greatly the restriction that aerial barrage thing is constructed to rotary drilling rig.

Fig. 2 is mast height of the present utility model and balance weight stepless duty front view when regulating back type rotary digging driller mast indentation minimum state;
Fig. 3 is that mast height of the present utility model and balance weight stepless regulate back type rotary drilling rig travel position front view.
Detailed description of the invention
For making the utility model become apparent, hereby with preferred embodiment, and accompanying drawing is coordinated to be described in detail below.
As shown in Figure 1, all hydraulic caterpillar mast height of the present utility model and balance weight stepless regulate back type rotary drilling rig to comprise assembly 8 of getting off, and assembly 7 of getting on the bus is connected with assembly 8 of getting off by revolving support.Rear counterweight assembly 9 connects the rear with assembly 7 of getting on the bus by infinitely variable horizontal extension mechanism.Jib lubbing mechanism 6 is being got on the bus on assembly 7 by pinned connection, mainmast 4 by pinned connection on jib lubbing mechanism 6.Unit head 5 hangs on the guide rail of mainmast 7 front end face.Drilling rod 3 by the front of steel wire hang in mainmast 4, and through unit head 5, is connected with drilling tool in the lower end of drilling rod 3.
Composition graphs 2, all hydraulic caterpillar mast height of the present utility model and balance weight stepless regulate back type rotary drilling rig to comprise secondary mast 2.Mainmast 4 is cavity structure, and the vertical telescoping mechanism of infinitely variable is located in the cavity of mainmast 4.Secondary mast 2 is connected with mainmast 4 by the vertical telescoping mechanism be located in mainmast 4, and catead 1 is connected to the top of secondary mast 2 by bearing pin and bolt, after catead 1 walked around by the wire rope of drawing below catead 1, drilling rod 3 is hung on mainmast 4 front.
When rotary drilling rig works, assembly 8 of getting off is responsible for walking and displacement, be located at the dynamical system of getting on the bus in assembly 7, hydraulic system and electric-control system provide power and action to guide to rig, its each action is normally worked, jib lubbing mechanism 6 regulates the verticality of mast and supports mainmast 4, mainmast 4 is provided with master winch and moves up and down to promote drilling rod 3, mainmast 4 is provided with a pressurization oil cylinder simultaneously, drag unit head 5 to move up and down, pressure is applied to drilling rod 3, drilling rod 3 drives drilling tool to creep into by the rotation of unit head 5 and pressurization and soil is unloaded in lifting, complete boring action.
When rotary drilling rig works out of doors, the height of mast can be regulated according to the environment of job site, install and secondary mast 2 can be driven to do upper and lower stepless free-extension with the vertical telescoping mechanism in mainmast 4 chamber, the height that secondary mast 2 stretches out is higher, machine gravity will move forward, after being now located at rear counterweight assembly 9 break-in at assembly 7 rear of getting on the bus, stepless stretches, and to ensure that the center of gravity of complete machine can not offset, makes rotary drilling rig can smooth working.
Otherwise, when rotary drilling rig is constructed under low clearance environment in factory building, in tunnel etc., secondary mast 2 can be recovered to the height of requirement by stepless, the rear counterweight assembly 9 being now located at assembly 7 rear of getting on the bus is recycled to certain distance ensures that complete machine center can not offset by telescoping mechanism is also corresponding, thus ensures that rig works stably.
When rotary drilling rig is when transporting, secondary mast 2 is retracted to minimum by the vertical telescoping mechanism being located at mainmast 4 inside, rear counterweight assembly 9 is also received to nearest from assembly 7 of getting on the bus, by jib lubbing mechanism 6 and the mast oil cylinder being located at mast rear, mainmast 4 was fallen, back with get on the bus above assembly 7, catead 1 is rotated by bearing pin and fell to certain position, assembly 8 of getting off is received to the narrowest, disassemble drilling rod and drilling tool can carry out entrucking transport, not superelevation not overlength when ensureing transport, not ultra-wide and shorten complete machine transportation lengths, disassembling of big-movement need not be carried out can conveniently shift.
