Between the hose 52 that connects, hose 52 can arbitrarily bend, it corresponds to the turning point of cursor 2, and pipeline connects when such cursor 2 is bent
Connect unaffected.
With reference to Fig. 2, operation principle is described below, jetting overall apparatus 4 through walls is corresponded to being worn in manipulation cursor 2
After the wall locations of wall jetting, start jetting overall apparatus 4 through walls, drilling motor 441 and give stepper motor 431 to start work, drilling
Motor 441 is driven drill bit connecting tube 443 by travelling gear 445 and rotates, and interlocks drilling pipe 42 and rotates, and drilling pipe 42 starts to bore to metope
Cut, drive screw 432 to rotate to stepper motor 431, since transmission shell 4332 is connected with connection sheet 434, connection sheet 434 connects again
Bearing fixed seat 442, and bearing fixed seat 442 is fixedly disposed on fixed frame 41, so as to understand that transmission shell 4332 is not
Rotatably, and transmission nut sliding block 4331 slide axially structure limitation under can transmission shell 4332 in slide axially, because
This leading screw 432 rotates, and drives 432 other end of screw in transmission shell 4332 of transmission nut sliding block 4331 to slide, compresses spring
4333, the elasticity tension of spring 4333 acts on transmission shell 4332, and transmission shell 4332 drives drill bit to connect by connection sheet 434
Adapter 443 is promoted to metope, the feed of drilling pipe 42 is carried out drilling, or perhaps drilling pipe 42 is pressed in metope all the time to metope pressure
On be conducive to drilling work progress because during drilling drilling pipe 42 be slowly drilling polishing pierce rather than
At every moment pushing ahead, drilling pipe 42 can not promote always under the reaction force of metope, therefore to stepper motor without when
Feed work is carved, and the start and stop work to stepper motor is, the screw 432 in transmission shell 4332 of transmission nut sliding block 4331 is another
End is slided drives pretension limit switch driving lever 4334 at the same time, switchs the movement of 4336 directions to pretension stop spacing, in drilling pipe 42 not
When can continue to promote, transmission nut sliding block 4331 can compress spring 4333 and drive the triggering pretension of pretension limit switch driving lever 4334 to stop
Only limit switch 4336, make to be stopped to stepper motor 431, and drilling pipe is still able to hold under the elasticity tension effect of spring 4333
Continuous to withstand on metope, the elasticity tension effect same purpose of spring 4333 is slowly crept into drilling pipe in transmission nut sliding block 4331
While one section, transmission nut sliding block 4331 retracts drive pretension limit switch driving lever 4334 also slowly to feed motor drive direction
Moved to pretension limit switch 4335, until triggering pretension limit switch 4335, starts and work to stepper motor, drive screw rod transmission
Transmission nut sliding block 4331 repeats the above steps, until completion through walls, while the transmission shell 4332 for being fed start stop apparatus 433 moves
Move to the screw other end and trigger feed reset switch, make feed motor reversal, be fed open under the drive of transmission nut sliding block 4331
Stop device 433 retracts initial position, drives 443 drilling pipe of drill bit connecting tube to shrink back back initial position, while it is tactile to be driven shell 4332
To issue into shutdown switch, that is, stop the work to stepper motor, manipulation drilling machine motor is stopped, that is, completes once to creep into work,
Then manipulation water cannon big gun head starts jetting and puts out a fire, and in drilling, jetting washes away cooling if needed, and water cannon big gun head also can be into
Row jetting, can open video camera in the course of work of jetting overall apparatus 4 through walls and carry out shooting observation.Manipulate and rotate after the completion of fire extinguishing
Arm folding.
The product form and style of above-described embodiment and schema and non-limiting the utility model, any technical field
The appropriate change or modification that those of ordinary skill does it, all should be regarded as not departing from the patent category of the utility model.
