Description

The ampere of dry-and wet-type auger shows and the hand automatic operation device

The ampere that the utility model relates to a kind of dry-and wet-type auger shows and the hand automatic operation device, specifically, be meant a kind of one ampere of display unit of above the motor of dry-and wet-type auger, installing, and be expected when its bit bore, keep its drill bit in optimum state, avoid bursting apart or wearing and tearing of drill bit, but and this penetration rate of automatic or manual operation control and torsion, finish the work fast and ensure bit life and be expected to reach.

Present building adopts steel concrete to build more, after building is finished, when carrying out operations such as water power, air-conditioning, fire engineering and electric pipe arrangement, meet with sometimes that metope stops and need to implement bore operation, facility in order to construction is carried out, and traditional bore operation system carries out with the vibrating type electric drill, stirs up a cloud of dust but control difficult and easily cause when operate because of it, cause the pollution of workplace and the trouble of dealing with problems arising from an accident, thereby the use of dry-and wet-type auger is just arranged.

Commonly use the Wet-dry auger, the mode of its drilling mainly makes drill bit pressurized drilling wall with manual hand lever, its control mode is to hole with artificial feeling, yet, because the control of sensation, so situation that overexerts or firmly kick the beam when often drilling being arranged and can't knowing, when overexerting, make its drill bit burst apart or wear and tear easily, and when firmly kicking the beam, can make the empty mill of brill tooth and not have drilling, cause the abrasion of its drill bit.

The purpose of this utility model provides a kind of ampere in the wet boring machine and shows and the hand automatic operation device, makes auger be in optimum Working so that can control, and can prolong the application life of drill bit.

The utility model is to realize like this, it comprises that a holder and its rank establish a profile of tooth guide rail and hold for the motor guide bracket and establish, and one hand lever control motor guide bracket along the feeding of profile of tooth guide rail or give up the throne, hold in the motor guide bracket and to establish a motor, motor spindle is with an adapter and is unitary rotation, and this adapter inside is provided with suitable space, and establish a water inlet pipe at a side joint, and this adapter can connect and establish suitable joint, prolong pipe and drill bit, and this bit exterior is overlapped a water-collecting tray, establishes gutter at this water-collecting tray; And the action of this auger is driven via motor drive shaft by motor, the transmission of power transmission shaft and main shaft and drive drill bit drilling on the main shaft, characteristics are: the top of this motor is provided with one ampere of display unit, force value when the pointer of this display unit shows its boring at any time, and on its apparatus surface, establish a best boring value range, when its bit drills during to the higher position of reinforcing bar or hardness, the show value of ampere display unit improves, this moment can be rapidly with the pressure reduction of its hand lever, and can keep the boring of its drill bit at one's best at any time, and avoid bursting apart or wear and tear and protecting motor of drill bit, clutch, there are not gear wheel and pinion on the power transmission shaft in addition, and its main shaft is provided with pinion and gear wheel, make its main shaft pinion produce drilling effect at a high speed by engaged transmission axle gear wheel by manually controlling its hand gear, be applicable to little drill bit; Or its main shaft gear wheel engaged transmission axle pinion produces the drilling effect of low speed, be applicable to big drill bit, and detect number with its ampere and cooperate control cabinet and can produce and quicken feed fractional motor pace when its auger starts power supply, the feed fractional motor of drill bit contact and beginning drilling work is replied normal speed, drill bit slows down feed fractional motor pace when meeting with reinforcing bar, descend rapidly when recording electric current, control cabinet promptly cuts off the power supply, stops the action of feed fractional motor and auger automatically, and realizes finishing fast drilling work.

Further, sheathed big pinion on the main shaft of the present utility model, in the boring of the main shaft between its two gear, set firmly a latch, big pinion latch ends tool brake groove, and end is urged by spring in addition, big pinion is little, the gear wheel of engaged transmission axle respectively, and its big pinion is pressed by dialling of striking gear, make it have only a gear brake groove blocking latch, reaching dialling of striking gear according to this cuts and the total number of teeth in engagement ratio is changed, thereby the change speed of mainshaft, make it be applicable to the drive drilling of big or small drill bit respectively;

The utility model also has one to be integral the gear shift lever of setting with this striking gear, make also swing thereupon of this gear shift lever when changeing its hand gear, and its gear shift lever length extends on the adjacent surface of large and small gear, and when striking gear was stirred, its gear shift lever can push the large and small gear of main shaft; Or this striking gear also may be made in the gear shift lever of hand gear, is arranged on the slide rail, and the front end of this gear shift lever extends on the adjacent surface of large and small gear, equally can the large and small gear of main shaft forced to move.

The utility model has the advantages that:

1, eliminates the shortcoming of prior art, can show its drilling state at any time, and make the operator can be, operation can be finished smoothly and can not make drill bit motor overload or clutch excessive slip impaired with the drilling pressure drilling hole of the best;

2, be provided with the safe holding device of overload in the ampere display unit, when making boring, action take place promptly to stop at once, protection facility safety if any the situation of transshipping;

3, can be manually or the control of automaticallying switch, the drill bit that makes auger reduction of speed and increase torsion when getting into reinforcing bar, be beneficial to the drilling reinforcing bar, and when its drill bit gets into the cement place, automatically switching to speed up the place and torsion reduces, make drill bit bore the cement part, reach drilling time decreased and bit life and prolong with fast speeds;

4, can be by striking gear, control its pinion gear wheel and produce high torsion and change, enable to cut hard objects such as reinforcing bar.

5, can control pinion middle gear wherein and the variation that produces higher rotation speed and less torsion by striking gear, make softer objects such as machinable cement, and fulfil assignment with fast speeds.
