Car dress multipurpose engineering driller

The utility model relates to a kind of engineering the drilling equipment that industry grounds such as construction work, energy communications are handled, especially a kind of simple and efficient car dress multipurpose engineering driller.

In the prospect technology, along with carrying out of market Large scale construction engineering, bored pile has become the leading role of engineering foundations such as high-rise building, highway, bridge, large-scale factories and miness, according to the construction needs, drilling machine also improves step by step and develops, as rigs such as positive and negative circulation, impacts, though its advantage is arranged, but all belong to the mud pore-forming, produce a large amount of mud during pore-forming, get rid of the difficult problem that mud has become domestic and international rig industry.Domestic solid revolves the formula of digging does not have mud to be popular, but its equipment mostly adopts the in bulk at the tripod structure rig of the seventies production, this brill is by A-frame, simple and easy twin drum winch, compositions such as rig floor, operating principle is to rotate drilling rod by the rig floor square hole of frame on A-frame, drilling bucket creeps into, use the twin drum winch of laying on the spot to promote drilling rod and drilling bucket, artificial spoil disposal on the spot, every one-tenth one drilling machine removes and installs and moves the hole once, this machine advantage is simple, expense is low, but it is low that its shortcoming is an efficient, because the dismounting of semi-mechanized operation rig is frequent, workload is big, and personnel's equipment breakdown is many.The telescopic drill rod of external import revolves control rig, walking hydraulic drive, and its advantage is that pore-forming creeps into high efficiency, and shortcoming is a function singleness, costs an arm and a leg the operating expenses height.

The purpose of this utility model is in order to overcome the weak point in the above-mentioned background technology, to develop a kind of car dress multipurpose engineering driller, and is simple and efficient, accelerating construction progress, and the reduction construction cost can either have the rotary digging drilling hole purposes, also has pump and lifts anti-circulatory function.

The novel technical solution of this reality is as follows:

Comprise: vehicle bracket (1) is gone up assembling hoist engine (2), the arm that can erect supports (10) and arm support (7), wherein arm supports the end square arm of the hinged framework that erects (8) of (10) and hydraulic prop (9), it is characterized in that: hoist engine (2) is gone up the drilling tool of the wire rope (11) of output through arm (8) upper end top block (13) connecting band drilling rod guiding (14), ground way (18) on the arm (8) is gone up slip rig floor (17) and the drilling rod guiding (14) that assembling can independently move up and down, six side's vertical shafts (6) pass the interior Hollow Transmission Shafts of slip rig floor (17), be connected with the gear-box (4) that is positioned at arm (8) below, gear-box (4) input connects hoist engine (3) front axle through universal transmission (3).

Technical solution of the present utility model also comprises:

Described drilling tool is the telescopic drill rod (16) that has drilling rod guiding (14), up and down telescopic drill rod (16) passes the slip rig floor (17) of driving, telescopic drill rod (16) lower end connects drilling bucket (20), and there is the liftable hydraulic pressure spoil disposal plate (21) that is the inclined-plane drilling bucket (20) below.

Described drilling tool is the kelly bar (25) that has water tap (23) and slip power supply (24), and kelly bar (25) lower end connects the drilling rod (27) that has submersible pump (26), and drilling rod (27) passes the slip rig floor (17) of driving.

The square arm of framework (8) the below hinged liftable hydraulic pressure supporting plate (22) in hydraulic prop (9) end of hydraulic control, this supporting plate (22) is gone up the hinged liftable hydraulic pressure spoil disposal plate (21) that is the inclined-plane in useful hydraulic prop (9) end.

Advantage of the present utility model and effect:, creep into so be more convenient for operation fast owing to adopt hydraulic pressure supporting plate and spoil disposal plate (1), has improved drilling efficiency, has reduced manpower.(2) owing to self-contained telescopic drill rod rotary drilling rig on automobile, adopt machine driving and hydraulic pressure to pass the technical scheme that combines, solved to promote and crept into, pressurize, the simplification of operations such as spoil disposal, reduce the machine-building cost, improved construction speed, reduced construction cost.(3) owing to adopt the technical scheme of assembling transmission vertical shaft in the middle of the square arm, power is delivered on the rig floor that can slide up and down by vertical shaft, has solved motor and be contained on the rig floor Fraquent start and the problem of easy to change speed not, saved motor and power consumption.(4) integrally-built change, cost of the present utility model has reduced more than 20 times than the rotary drilling rig of foreign import; Compare with domestic similar rig, make original 3 people operation be embodied as 1 people operation, saved manpower greatly, improved efficiency of construction, also reduced construction cost simultaneously.

The utility model description of drawings is as follows: Fig. 1 is overall structure and telescopic drill rod structural representation, and Fig. 2 is that overall structure and pump are lifted the anti-structural representation that follows.Above-mentioned number in the figure is described as follows: 1-vehicle bracket, 2-hoist engine, the universal transmission of 3-, 4-(circular cone) gear-box, 5-supporting leg, 6-six side's vertical shafts, 7-arm support, 8-framework square arm, 9-hydraulic prop, 10-hangs wall and supports, 11-wire rope, 12-intermediate pulley, the 13-top block, 14-drilling rod guiding, 15-rig floor, hydraulic cylinder, the 16-telescopic drill rod, 17-slip rig floor, 18-slideway, 19-(hook at the bottom of the drilling bucket) bumps pin, 20-drilling bucket, 21-hydraulic pressure spoil disposal plate, 22-hydraulic pressure supporting plate, the 23-water tap, 24-slip power supply, 25-kelly bar, 26-(sandstone) submersible pump, the 27-drilling rod.

Following adjoint is described in further detail: referring to Fig. 1, vehicle bracket 1 bottom connects supporting leg 5, top wire rope hoist 2, hinged arm support 10 and the hydraulic prop 9 that erects, the arm support 7 hinged framework square arms of fixing on the carriage 18 that erect, circular cone that arm 8 lower bottom parts are fixing or 4 outputs of the gear-box of other form connect driving six side's vertical shafts 6, six side's vertical shafts 6 pass Hollow Transmission Shafts in the up and down slip rig floor 17, transferring power, up and down telescopic drill rod 16 are also passed rig floor 17 and are obtained torque.
