Accompanying drawing explanation
In order to be illustrated more clearly in the embodiment of the present invention or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment below, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is that of the present invention revolving digs guide rod type narrow wall Seepage hydraulic grab one example structure schematic diagram;
In figure: 1 capstan winch; 2 hydraulic oil pipes; 3 leading trucks; 4 hydraulic cylinders; 5 adpting flanges; 6 grab buckets; 61 topping machanisms; 62 gear engagement mechanisms; 7 rotary drill rods; 8 masts; 9 unit heads.
Detailed description of the invention
Below in conjunction with the accompanying drawing in the embodiment of the present invention, be clearly and completely described the technical scheme in the embodiment of the present invention, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, the every other embodiment that those of ordinary skill in the art obtain, all belongs to the scope of protection of the invention.
As shown in Figure 1, one is revolved and is dug guide rod type narrow wall Seepage hydraulic grab, comprising: unit head 9, rotary drill rod 7, leading truck 3, hydraulic cylinder 4 and two grab buckets 6; The two ends of rotary drill rod 7 are connected with leading truck 3 and unit head 9 respectively, and unit head 9 drives rotary drill rod 7 to drive leading truck 3 to move; Hydraulic cylinder 4 is arranged on leading truck 3, and two grab buckets 6 are all connected on the piston rod of hydraulic cylinder 4, and hydraulic cylinder 4 drives two grab buckets 6 close up or open.Wherein two grab buckets 6 can be coupled together by axis of rotation, do relatively to rotate close up to complete or open around axis of rotation.
During work, unit head 9 drives rotary drill rod 7 to rotate, and then drive leading truck 3 and two of being connected with leading truck 3 by hydraulic cylinder 4 to grab bucket 6 to rotation, when two grab buckets 6 rotate to correct operating position, the piston rod of hydraulic cylinder 4 stretches out and two grab buckets 6 is opened, cut the earth along with rotary drill rod 7 declines, being retracted by the piston rod of hydraulic cylinder 4 after allowing makes two grab buckets 6 close up, complete and grab geotechnique's work, and by the rising of rotary drill rod 7 with rotate the soil dug is moved to other positions, stretched out by the piston rod of hydraulic cylinder 4 again and make two to grab bucket 6 to open soil is discharged, complete a work period.Driving two grab buckets 6 to close up by hydraulic cylinder 4 or having opened to grab soil and unload geotechnique makes the work period become shorter.
Wherein operating personnel adjust rotary drill rod 7 according to the depth requirements of grooving, can be adjusted the verticality on two grab bucket 6 and ground by adjustment rotary drill rod 7 and the verticality on ground simultaneously, thus the overall verticality of the equipment of guarantee.Thus ensure that the verticality of grooving, improve operating efficiency.This revolves and digs guide rod type narrow wall Seepage hydraulic grab and directly can carry out excavation slot grooving at preposition, does not need to carry out in advance leading native operation, and perfusion mud can carry out with fluting simultaneously.This equipment is used for narrow wall impervious wall technology, such as, become slot thickness to be 300mm, 400mm, 500mm, 600mm.
More preferably, two grab buckets 6 are provided with pitch wheel engaging mechanism 62.Gear engagement mechanism 62 can be the identical and intermeshing sector gear of two moduluses as described in Figure 1, when one of them grab bucket 6 rotates, by the engagement of gear engagement mechanism 62, makes another grab bucket 6 can do synchronous relative rotation.Ensure that the work uniformity of two grab buckets 6.
More preferably, two grab buckets 6 all arrange topping machanism 61.Topping machanism 61 can be the metal derby with cutting edge be welded in grab bucket 6, when two grab buckets 6 carry out grabbing geotechnique do time, topping machanism 61 can directly cut cell wall, makes cell wall more regular, avoids fluting to occur caving in, ensure that work quality.
Can the examination of the side of enforcement as one, also comprise capstan winch 1 and hydraulic motor, capstan winch 1 is connected with hydraulic motor, and rotates under the driving of hydraulic motor; The hydraulic tube 2 of hydraulic cylinder 4 is wrapped on capstan winch 1.
When rotary drill rod 7 drives leading truck 3 to decline, hydraulic cylinder 4 also sleeping leading truck 3 declines, the hydraulic tube 2 of two hydraulic cylinders 4 can elongate or shorten along with the change in location of hydraulic cylinder 4, rotate by adopting fluid motor-driven capstan winch 1, adjustment is wrapped in the length of the hydraulic tube 2 on capstan winch 1, and hydraulic tube 2 can be made to adapt to the change in location of hydraulic cylinder 4 in real time.Wherein capstan winch 1 can be arranged on the support of unit head 9, it should be noted that and other driving mechanism also can be adopted to rotate to drive capstan winch 1.
Particularly, the quantity of hydraulic cylinder 4 is two, and two hydraulic cylinders 4 are grabbed bucket with two respectively and 6 to be in transmission connection; The quantity of capstan winch 1 is two, and the hydraulic tube 2 of two hydraulic cylinders 4 is wrapped on two capstan winches 1 respectively.
As a kind of embodiment, also comprise adpting flange 5; Rotary drill rod 7 is connected with leading truck 3 by adpting flange 5.Can be convenient to this like this and revolve the dismounting or installation of digging guide rod type narrow wall Seepage hydraulic grab, bring conveniently to the replacing of service work and rotary drill rod 7.And leading truck 3 is connected on rotary drill rod 7 by adpting flange 5 and is convenient to adjust leading truck 3, be conducive to rectification work
As a kind of embodiment, also comprise the mast 8 be connected with external mobile device; Unit head 9 is arranged on mast 8.Like this can by mast 8 this is revolved dig guide rod type narrow wall Seepage hydraulic grab mobile device mounted externally (as rotary drilling rig or other can the equipment of movement) on
In sum, by means of technique scheme of the present invention, described rotary drill rod is driven to drive described leading truck to move by adopting described unit head; And grab bucket described in described hydraulic cylinder and two and be in transmission connection, close up in order to drive two described grab buckets or the technical scheme opened to make the present invention have structure simple, with low cost, construction technology is simple, short construction period, the advantage that operating efficiency is high.
