The structure that slides axially is provided between block 4331, shown in figure is axially to offer sliding groove on the transmission shell 4332, institute
The sliding shoe that transmission nut sliding block 4331 is provided with embedded sliding groove is stated, the end of the transmission shell 4332 can block transmission
Nut slider 4331, the both ends of the spring 4333 withstand on transmission nut sliding block 4331 and the transmission end set of shell 4332 respectively
Transmission bottom on, corresponding to be disposed on transmission outer for the pretension limit switch 4335 and pretension stop spacing switch 4336
On shell 4332, the one end of pretension limit switch driving lever 4334 connection transmission nut sliding block 4331, the other end is corresponding to be limited in pretension
Between bit switch 4335 and pretension stop spacing switch 4336, the transmission nut sliding block 4331 can make pretension spacing when sliding
Switch shift lever 4334 triggers pretension limit switch 4335 or pretension stop spacing switch 4336, the feed He of reset switch 4337
Feed shutdown switch 4338 corresponds to screw mandrel 432 and is driven the setting of stroke both ends respectively, and the transmission nut sliding block 4331 slides into silk
The triggering of transmission shell 4332 feed shutdown switch 4337 or feed reset switch 4338, the biography can be made during 432 stroke both ends of bar
Dynamic shell 4332 connects connection sheet 434.
The pipe-line system connects jetting overall apparatus 4 through walls and is used to supply water, and specifically connects water cannon connecting tube 443, described
Pipe-line system as shown in figure 1, include the fixing pipe 51 being respectively fixedly disposed on each cursor 2 and adjacent two fixing pipe 51 it
Between the flexible pipe 52 that connects, flexible pipe 52 can arbitrarily bend, and the turning point of its corresponding cursor 2, pipeline connects when such cursor 2 is bent
Connect unaffected.
With reference to Fig. 2, operation principle is described below, makes jetting overall apparatus 4 through walls is corresponding extremely to be 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 rotated, and interlocks drilling pipe 42 and rotates, and drilling pipe 42 starts to bore to metope
Cut, drive screw mandrel 432 to rotate to stepper motor 431, because 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 mount 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 the other end of screw mandrel 432 in transmission shell 4332 of transmission nut sliding block 4331 to slide, compression 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 promotes 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 advantageous 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 mandrel 432 in transmission shell 4332 of transmission nut sliding block 4331 is another
One end is slided drives pretension limit switch driving lever 4334 simultaneously, the movement of 4336 directions is switched to pretension stop spacing, in drilling pipe 42
When can not continue to promote, it is pre- that the meeting compression spring 4333 of transmission nut sliding block 4331 drives pretension limit switch driving lever 4334 to trigger
Tight stop spacing switch 4336, makes to be stopped to stepper motor 431, and drilling pipe still can under the elasticity tension effect of spring 4333
Enough persistently to withstand on metope, the elasticity tension effect same purpose of spring 4333 is in transmission nut sliding block 4331, in drilling pipe slowly
While creeping into one section, transmission nut sliding block 4331 retracts drive pretension limit switch driving lever also slowly to feed motor drive direction
4334 move to pretension limit switch 4335, until triggering pretension limit switch 4335, starts and worked to stepper motor, drive silk
Bar transmission transmission nut sliding block 4331 repeats the above steps, until completion through walls, while it is fed the transmission shell of start stop apparatus 433
4332 are moved to screw mandrel other end triggering feed reset switch, make feed motor reversal, under the drive of transmission nut sliding block 4331
Feed start stop apparatus 433 retracts initial position, drives the drilling pipe of drill bit connecting tube 443 to shrink back back initial position, while be driven shell
4332 triggering feed shutdown switches, that is, stop the work to stepper motor, and manipulation rig motor is stopped, that is, completes once to creep into
Work, then manipulate water cannon big gun head and start jetting and put out a fire, jetting washes away cooling, water cannon big gun head if needed in drilling
Jetting can be carried out, can open video camera in the course of work of jetting overall apparatus 4 through walls carries out shooting observation.Manipulated after the completion of fire extinguishing
Cursor folding.
Above-described embodiment and schema and non-limiting product form of the present utility model and style, any art
The appropriate change or modification that those of ordinary skill is done to it, all should be regarded as not departing from patent category of the present utility model.
