Description

A kind of rotary drilling rig

One, technical field

The utility model relates to rig, particularly novel a kind of rotary drilling rig.

Two, background technology

As everyone knows, Atlas excavator stable performance, high efficiency, be the leader in the excavator industry, 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 to the Atlas excavator so, make it to become rotary drilling rig, to satisfy the demand in market?

Three, summary of the invention

At above-mentioned situation, for overcoming the defective of prior art, the purpose of the utility model just provides a kind of rotary drilling rig, can effectively solve rotary drilling rig expense height, use inconvenience and waste fund, problem of resource.

The technical scheme of its solution is, on the structure of Atlas excavator, 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, structure of the present utility model is to comprise the triangle linking arm, pile frame and chassis, the triangle linking arm is housed on the chassis, on the triangle linking arm oil cylinder is housed, the triangle linking arm links to each other respectively at pile frame with oil cylinder, pile frame is fixed on the chassis, dynamic head on the pile frame, drilling rod is housed on the unit head, there is rope the drilling rod upper end, the top pulleys that the rope other end is walked around pile frame upper end is fixed on the main winch on the chassis, and there is drill bit the drilling rod lower end.

The utility model structure uniqueness, easy to use, cost is low, economize on resources, and really realized the brand-new transformation of excavator and the utilization once more of waste product, and the effect higher than original utilization rate, is the innovation on the rotary drilling rig.

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 triangle linking arm, pile frame and chassis, triangle linking arm 12 is housed on the chassis 1, oil cylinder 4 is housed on the triangle linking arm 12, triangle linking arm 12 links to each other respectively at pile frame 5 with oil cylinder 4, pile frame 5 is fixed on the chassis 1, on the pile frame 5 dynamic 10, drilling rod 9 is housed on the unit head 10, there is rope 7 drilling rod 9 upper ends, the top pulleys 6 that rope 7 other ends are walked around pile frame 5 upper ends is fixed on the The One On The Chassis main winch 3, and there is drill bit 11 drilling rod 9 lower ends.

In order to guarantee result of use, secondary hoist engine 2 is arranged on the said chassis 1, on the secondary hoist engine 2 rope is arranged, the top pulleys 6 that the rope other end is walked around pile frame 5 upper ends is connected to suspension hook 13.

On the said pile frame 5 guide rail is arranged, unit head 10 is on the fixed oil cylinder on the pile frame 58 is fixed on guide rail on the pile frame 5.

Said oil cylinder 4 is two, is symmetrically placed on the triangle linking arm 12.

Concrete enforcement of the present utility model is, at first, triangular form linking arm 12 usefulness bearing pins are connected on the chassis 1, be used to promote the main winch 3 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, rear end of triangular form linking arm, 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 following joint of pile frame 5, going up between joint and the following joint of pile frame 5 is hinged by bearing pin, 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, 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.

By said structure as can be seen, disassemble the big arm of excavator during transformation, dipper and scraper bowl and with parts such as oil cylinder, keep chassis 1 and on the system that comprised, unit head 10 moves up and down at oil cylinder 8 effect lower edge guide rails, drilling rod 9 promotes up and down under the effect of main winch 3, can reach the necessary height of rotary drilling rig work, during work, the dynamical system that connects top bottom-disc 1, operating system etc., guarantee that pile frame 5 becomes 90 ° with horizontal plane, handle electric switch, unit head 10 begins rotation, handling fixed oil cylinder 8 simultaneously presses down, the rotation of unit head 10 has at this moment driven the rotation of drilling rod 9, and the rotation of drilling rod 9 drives the rotation of drill bit 11, adds the downforce of fixed oil cylinder 8, impel drill bit 11 constantly to the deep under ground rotary drill, treat soil, after sand etc. were filled drill bit, steering maneuver head 10 stopped the rotation, and promoted master winch 3 simultaneously, drilling rod 9 and drill bit 11 are risen together, after rising to more than the ground, handle chassis 1 and rotate to the appropriate location, open drill bit 11, pour out foreign material such as earth, make rotation position just now, chassis once more, whereabouts drilling rod and drill bit, rotary power head, handle so repeatedly, dig to desired depth up to revolving.

Do not work or when transporting, dismounting is drilling rod 9 and drill bit 11 (herein be that bearing pin is hinged) down, master cock stretches out oil cylinder 4, and pile frame 5 keeps flat, the top and the bottom of folding pile frame 5, not only safely but also save the space.Favourable solution the problem of main equipment transportation inconvenience.

The utility model utilizes existing rotary drilling rig, the functional performance of the excavator of Ti Gaoing not only, and realize the utilization once more of waste and old equipment, cost and resource had both been saved, its value is improved, and is the innovation on the rotary drilling rig, has remarkable economical and social benefit.
