Accompanying drawing explanation
Fig. 1 is the overall structure schematic diagram of a kind of construction material perforating device of the present invention.
Detailed description of the invention
Below in conjunction with Fig. 1, the present invention is described in detail.
According to a kind of construction material perforating device of embodiment, in order to the construction material 94 of lower section is punched, bag
Include to be resisted against the housing 91 of thing 9 fixed above, the upper side wall of described housing 91 be provided with two top pressure screw arbor assemblies 8,
Said two top pressure screw arbor assembly 8 is symmetrical arranged about the longitudinal axis of described housing 91 and each includes: be fixed on described
Screwed hole 821 spiral shell being screwed in the lower end wall of sleeve 82 and the described sleeve 82 that is screwed on the upper side wall of housing 91
Top pressure screw rod 81 that stricture of vagina coordinates, be positioned at described in be screwed under sleeve 82 and with the described top fixing spiral shell being connected of pressure screw rod 81
Bar gear 813 and the adapter sleeve barrier part 88 being connected with the lower end of described top pressure screw rod 81 by lower thrust-bearing 811, described
Adapter sleeve barrier part 88 by jointed shaft neighboring edge position with boring assemblies installing plate 72 hinged, boring assemblies installing plate
The downside of 72 is provided with the drilling driving device 7 coupled with drill head 71 power, thus drives described drill head 7 to build described
Build material 94 to hole;Wherein, the interior top pressure that is provided above at described screw gear 813 of described housing 91 drives motor liter
Fall erecting bed 62, described top pressure drives and is provided with and drives gear 61 power to join on the downside of the centre position of motor lifting erecting bed 62
The top pressure connect drives motor 6 and is each passed through the sleeve 82 that is screwed of said two top pressure screw arbor assembly 8 at two ends, left and right
In vertical chute 820 and stretch in the sleeve 82 that is screwed accordingly and with the upper end of corresponding top pressure screw rod 81 by push away
Power bearing 812 connects, described top pressure drive motor lifting erecting bed 62 upper side by Flexible Connector 629 with described shell
The upper side wall of body 91 connects;Described driving gear 61 engages with two described screw gears 813 simultaneously, thus, when described top pressure
Drive motor 6 to rotate and drive the top pressure screw rod 81 of said two top pressure screw arbor assembly 8 can be relative to described screw thread when rotating
Fixing sleeve 82 moves downward and presses described boring assemblies installing plate 72 from top, two ends, so that the neck of described drill head 71
In portion's sliding eye in the lower wall of described housing 91 slide downward and make the end of described drill head 71 pierce described in build
Build in material 94;When described when described top pressure drive motor 6 reversely rotate time, it is possible to drive described drill head 71 to rise and leave
Described construction material 94,
Wherein, the lower right-hand side of described housing 91 is provided with a high-power blower 23, and described high-power blower 23 connects a gas transmission
Pipeline 21, one end of described gas pipeline 21 is connected with described high-power blower 23, and the other end of described gas pipeline 21 is arranged
Having purge nozzle 20, described purge nozzle 20 to be positioned at the right of described drill head 71, described gas pipeline 21 is along described housing
The bottom of 91 extends and described gas pipeline 21 is fixed by the bottom of snap close 22 with described housing 91, described high-power blower
23 in order to the end of described drill head 71 is pierced described construction material 94 punches time produced building chip blow away
Scatter, so that produced building chip will not be deposited in the periphery of described drill head 71 and affect described boring during punching
71 carry out drilling operation to described construction material 94.
Valuably or exemplarily, described top pressure drives motor lifting erecting bed 62 to be screwed in sleeve 82 with described
Vertical chute 820 is slidably matched for plane formula, thus prevents described top pressure from driving motor lifting erecting bed 62 relative to described spiral shell
Stricture of vagina is fixed sleeve 82 and is rotated.
Alternatively or exemplarily, described Flexible Connector 629 is spring.
Owing to can utilize symmetrical two top pressure screw rods that plate-like drill bit erecting device is carried out top pressure, therefore can keep away
Exempt from the generation of deflection in drill process, it is provided that stability during punching.Be additionally, since whole top hydraulic driver be positioned at centre and
Screw drive is pressed on the top of both sides simultaneously, therefore decrease the quantity of driver part.Due to plate-like erecting device and thereon
Drive motor trailing type to move up and down, therefore, it is possible to make full use of shell space, reduce whole shell dimension.Driven by top pressure
Motor lifting erecting bed is connected by elastic component with housing upper side wall, therefore, it is possible to trailing type partly or entirely offsets pressure-bearing and spiral shell
Load on pit, it is to avoid screw thread transships.Whole apparatus structure is stable, uses reliable, it is possible to effectively solve of the prior art
Problem.
By with upper type, those skilled in the art can make various within the scope of the invention according to mode of operation
Change.
