As everyone knows, CAT excavator high efficiency, quality is good, account for the leading position in excavator market, but because the restriction of excavator structure, can only carry out digging operation, and can not carry out stake work industry as rotary drilling rig, and along with the development of excavator technology, a lot of manufacturing firms are all at the excavator of production different model, this has just caused the saturated of excavator market, and it is limited to add the excavator construction ability, makes a lot of excavator clients must not abandon original excavator, and remove to buy expensive rotary drilling rig, therefore, make the client both waste fund and resource, can not participate in again among the construction of engineering, particularly under the situation of excavator Market competition, can carry out structural improvement and innovation to blocking special excavator so, make it to become rotary drilling rig, to meet the need of market?

Three, summary of the invention

At above-mentioned situation, overcome the defective of prior art, the purpose of the utility model just provides a kind of novel rotary drilling rig, can effectively solve existing rotary drilling rig uses inconvenient, cost height and resource, the problem of fund waste, the technical scheme of its solution is, on the basis of the special excavator of card, make improvements and innovate, promptly remove the big arm of excavator, equipment such as dipper and scraper bowl, keep the original chassis of excavator and (comprise running gear, engine system, the driver's cabin system, hydraulic system and electric system), design the pile frame of rotary drilling rig then by the existing performance parameter of excavator, unit head, the devices such as major-minor hoist engine of drill rod boring tool and lifting usefulness, at last by being connected with the chassis of original excavator and installing, and to original chassis secondary debugging, reach the duty of rotary drilling rig, in view of the above, the utility model comprises drilling rod, pile frame, linking arm and chassis, linking arm is housed on the chassis, oil cylinder is arranged on the linking arm, linking arm links to each other with pile frame respectively with oil cylinder, pile frame is fixed on the chassis, dynamic head on the pile frame, drilling rod is arranged on the unit head, there is drill bit the drilling rod lower end, there is rope the drilling rod upper end, the assembly pulley that the other end of rope is walked around pile frame upper end is fixed on the main winch on the linking arm, the utility model structure uniqueness, easy to use, cost is low, really realized the brand-new transformation of existing excavator and the utilization once more of waste product, and the effect higher than original utilization rate.

Four, description of drawings

Fig. 1 is a front view of the present utility model.

Fig. 2 is a left view of the present utility model.

Five, the specific embodiment

Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described in further detail.

Provide by Fig. 1, Fig. 2, the utility model comprises drilling rod, pile frame, linking arm and chassis, linking arm 12 is housed on the chassis 1, oil cylinder 4 is arranged on the linking arm 12, linking arm 12 links to each other with pile frame 5 respectively with oil cylinder 4, pile frame 5 is fixed on the chassis 1, on the pile frame 5 dynamic 10, drilling rod 9 is arranged on the unit head 10, there is drill bit 11 drilling rod 9 lower ends, there is rope 7 drilling rod 9 upper ends, and the assembly pulley 6 that the other end of rope 7 is walked around pile frame 5 upper ends is fixed on the main winch 2 on the linking arm 12.

In order to guarantee result of use, said linking arm 12 is the triangle linking arm.

Said assembly pulley 6 is fixed on the top of pile frame 5 through bearing pin.

Said pile frame 5 is made of inside and outside two-layer contractile hollow cylinder, on the pile frame 5 guide rail is arranged, and unit head 10 is fixed on the guide rail of pile frame 5 through oil cylinder 8.

Secondary hoist engine 3 is arranged at said pile frame 5 bottoms, on the secondary hoist engine 3 rope is arranged, and the assembly pulley 6 that the rope other end is walked around pile frame 5 tops is connected to suspension hook 13.

Of the present utility model being embodied as, at first, triangular form linking arm 12 usefulness bearing pins are connected on the chassis 1, be used to promote the main winch 2 of drilling rod 9 and drill bit 11 then by being bolted to the front end of triangular form linking arm 12, the secondary hoist engine 2 of other article of being used to sling is fixed by bolts to the side of pile frame 5, the front end pin-and-hole of triangular form linking arm 12 is used and hinged pile frame 5, hinged two oil cylinders 4 of the upper end pin-and-hole of triangular form linking arm, the other end of oil cylinder 4 is hinged on the mid portion of pile frame 5, pile frame 5 is divided into inside and outside two-layer, the internal layer convergent-divergent is in skin, can be flexible freely in skin, four top pulleys 6 are fixed with bearing pin in the top of pile frame 5, wire rope 7 one ends are fixed on the major-minor hoist engine, the other end is fixed on drilling rod 9 upper ends, the centre then is placed in the top pulleys 6, drilling rod 9 is through in the keyway of unit head 10, drill bit 11 is being fixed in the lower end, unit head 10 upper ends are connected on the pile frame 5 with oil cylinder 8, the side is through on the guide rail of pile frame 5, unit head just can move up and down at oil cylinder 8 effect lower edge guide rails like this, and drilling rod can promote up and down under the effect of main winch, has so just reached the necessary device of rotary drilling rig work.
