Background technology

At present, the construction machinery that often adopts in the well-digging operation is the stepped type trepan, CZ-150 type trepan (anti-circulating) as the production of Wuchang City, Heilongjiang Province water conservancy machinery Co., Ltd, this machine is a vehicle body by 6 tons of cab-over-engine trucks that are power with 6110 type Diesel engines, is loaded with derrick, hydraulic pressure pole, hoist engine, hoisting rope, operative position, water injecting pump and suction pump (working barrel), hydraulic pressure spike and hydraulic power system etc. on it.

There are rotating disk, tap and main drilling rod, suspender, device for exerting and drilling rod to move changing device on the derrick.

Before the construction operation, needing earlier four hydraulic pressure spikes on the vehicle body to be propped, is that power erects derrick come after the upright rotating shaft rotation of inclining with hydraulic pressure pole.

The power of hydraulic pressure pole and four hydraulic pressure spikes is from hydraulic power system, and hydraulic oil pump wherein provides hydraulic power, is exported by the power that the hydraulic control switch is controlled on each branch's oil circuit.

Motor is rotating disk, hoist engine, water injecting pump and suction pump by power transmission, and hydraulic oil pump provides power.

During drilling well, rotating disk drives main drilling rod, driving the interior a plurality of secondary drilling rods that are connected of well and the drill bit of lowermost end again tunnels downwards, main drilling rod and a plurality of secondary drilling rod that joins and drill bit all are hollow tubulars, main drilling rod is connected on the suction pump by tap and main sebific duct, the bottom of drill bit is uncovered, directly facing to soil layer, rock stratum to be tunneled.

Water injecting pump is connected with suction pump by serises connecting tube.Before the driving, pass through suction pump, main pump pipe, main sebific duct, tap and main drilling rod fills with water in well head by water intaking in the water injecting pump puddle from the side earlier, discharge air in the well; When spudding in, suction pump brings out the ground mud that produces in the pick commentaries on classics upwards with water back suction backwater hole, and the water in the puddle constantly replenishes in well by irrigation canals and ditches and keeps water circulation, and this is called as anti-circulating drilling well.

In driving, rotate jointly by the main drilling rod a plurality of secondary drilling rods that join of drive and the drill bit of bottom, truck engine transmits power by power transmission and gives rotating disk, drive engageable with it main drilling rod (also can drive the secondary drilling rod that is engaged with) by rotating disk again, downwards then relying on manually of the device for exerting of the application of force constantly moved the runner of the left back position of iron pipe lever drives vehicle body with hand (runner had two, each can put an iron pipe lever, can operate simultaneously by two people, also can be by one man operation) drive a cover chain on the derrick and drive tap and main drilling rod to pressing down, reach drill bit.Because of being that manpower drives, strength is very limited, and maximum also only can reach 1 ton.It is best suited for the mud stone condition, makes a call to 100 meters well this moment, needs 8～10 hours; When running into above the 1300MPa rock-soil layer, driving is difficult to downwards, hardly may.

The course of work that drilling rod moves changing device is, promote main drilling rod after, need the manual driven sprocket wheel to drive chain after pin-and-hole inserts pin, main drilling rod and tap could be moved inward at derrick and put in place, go into well and abdicate the space for hanging secondary drilling rod; Otherwise, they are shifted out before in the derrick enter the headwork position, need again manually take off pin from pin-and-hole.Changing-over successively will be with 5～7 minutes time, and subsequent process also is to switch so repeatedly, and time-consuming, efficient is also low, particularly ought be at dark, and the workman is difficult to see clearly, accurately operation.

During construction operation, need four-player usually at least, comprise hoist engine driver one people on the operative position, totally three people, quite lost labor lift secondary drilling rod, lift and exert pressure; And the secondary drilling rod of delivery fortune needs the special transport vehicle of adapted, at first needs secondary drilling rod is lifted on the other assigned work platform of trepan in car behind the scene, can be lifted by crane by suspender, and the workman lifts secondary drilling rod and very easily accidentally drops and cause serious industrial injury under tired situation.

When drilling well reaches the predetermined degree of depth, main drilling rod, secondary drilling rod and drill bit are proposed, the stepped type trepan moves backward, and hoist engine drives hoisting rope and through pipe of cement pulley down pipe of cement one joint one saved land and be lowered in the well always sign indicating number and then finish whole operations to well head.

With above-mentioned traditional mechanical system well-digging, exert pressure because of there being the dependence manpower; Hoist engine lifts main drilling rod (with the system of the iron chains on the suspender), secondary drilling rod (connecting with the drill rod thread on the suspender) in turn; Main drilling rod and tap are stopped in derrick, when leaving, are needed manually to insert, take off pin by turns, are unfavorable for very much operation after the darkness.So automation is poor, efficient is low, and when taking a lot of work, easily tired out, the cycle is long, and incompatible geological environment and operation from far-off regions in complexity are unfavorable for trying to meet the deadline for the project, and the wound benefit has not been given play to the potential that has trepan equipment now.

And, power relies on on-board engine fully, it as unique power when long-time, the big load operation, especially when environment temperature is higher than 25 ℃, the recirculated water of motor and the temperature of hydraulic oil rise very easily rapidly, can force the cooling that quits work of motor and hydraulic power system.

Also have, the power of hoist engine is from on-board engine and power transmission, operation power is steady inadequately, the moment of torsion of output is also big inadequately, also waste very much diesel fuel, meet water in the rainy day because of mechanical braking device and easily skid and can not work, the shut-down that causes of raining continuously may cause landslide in the well, loss drilling rod, drill bit and destroy in the past engineering, duration, quality and property all can be subjected to very big influence.
